DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the purpose, the technical solutions and the advantages of the present disclosure be clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and comprehensively with reference to the accompanying drawings. It is obvious that, the embodiments described below are only some embodiments of the present disclosure rather than all embodiments. Based on the embodiments in the present disclosure, some other embodiments, which are obtained by the person of ordinary skill in the art without paying creative labor, should all be included in the protection scope of the present disclosure.

At present, when the air conditioner performs a cooling operation under high-temperature weather, in order to improve a heat exchange efficiency of an outdoor unit, a spray cooling method may be used for the heat exchanger of the outdoor unit. Simultaneously, in order to ensure water conservation, an intermittent spraying method may be used generally, a water pump needs to be operated continuously under normal condition. However, when an intermittent spraying mode is used, the water pump needs to be turned on and turned off frequently. In this condition, a fault is prone to occur, so that a service life of the water pump is shortened.

In view of this, a spraying system, a method and an apparatus for controlling the spraying system, and an electronic device are provided in the embodiments of the present disclosure. In particular, the present disclosure relates to a spray cooling device, an air conditioner and a water conservation spraying control method. It can be ensured that, an intermittent spraying can be implemented in a spray cooling system including the water pump through switching of solenoid valves, damage to the water pump may be avoided while the purpose of spraying water and conserving water is achieved, a service life of the water pump is prolonged and user experience is improved.

In order to facilitate understanding of this embodiment, a method for controlling a spraying system disclosed in the embodiments of the present disclosure is described in detail.

The spraying system according to the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

The spraying system may include a water outlet device 1, a spraying branch 2, a backflow branch 3 and a nozzle 4. A water outlet 11 of the water outlet device 1, the spraying branch 2 and the nozzle 4 are communicated sequentially. The spraying branch 2, the backflow branch 3 and a water inlet 12 of the water outlet device 1 are communicated sequentially.

As shown in FIG. 1, a solid line branch in FIG. 1 represents the spraying branch, and a dotted line branch represents the backflow branch. A solenoid valve may be arranged in the spraying branch and/or the backflow branch, and the solenoid valve is configured to control turning on and turning off of the spraying branch and/or the backflow branch. That is, two-way solenoid valves may be respectively provided in the spraying branch and/or the backflow branch, and three-way solenoid valves may also be provided at an intersection of the spraying branch and the backflow branch. Thus, the turning on and turning off of the spraying branch and/or the backflow branch may be controlled through the solenoid valves.

When the spraying branch is turned on, liquid flowing out of the water outlet device may flow out of the nozzle through the spraying branch. When the backflow branch is turned on, the liquid flowing out of the water outlet device may flow into the water outlet device again through the backflow branch. The liquid flows into the water outlet device again through the backflow branch, such that the water pressure of the water outlet device may be improved, which means that, there is no need to increase the water pressure through the water pump.

If the intermittent spraying mode is adopted, the spraying branch may be turned on firstly, and the backflow branch is turned off for a period of time. In this condition, the liquid may flow out of the nozzle through the spraying branch. Then, the backflow branch is turned on, the spraying branch is turned off for a period of time, in this condition, the liquid flows into the water outlet device again through the backflow branch, the water pressure of the water outlet device may be increased, there is no need to increase the water pressure through the water pump in the entire intermittent spraying process, the service life of the water pump may be prolonged, and the damage to the water pump is avoided.

According to the spraying system, the apparatus and the electronic device provided in the embodiment of the present disclosure, the spraying system may enable the liquid flowing out of the water outlet device to flow back to the water outlet device through the backflow branch. In this method, it can be guaranteed that, the intermittent spraying in the spraying system including the water pump may be realized through switching of the solenoid valves, and a water supply pressure is improved through the backflow branch. Thus, the water pump does not need to be turned on and turned off frequently, occurrence of temperature rise in the pump would not be caused, the service life of the water pump may be prolonged, the damage to the water pump is avoided, and the user experience is improved.

Another spraying system according to the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Another spraying system is provided in the embodiments of the present disclosure. This spraying system is implemented on the basis of the above-mentioned embodiments. FIG. 2 illustrates a schematic structural diagram of another spraying system. In the spraying system in this embodiment, the spraying branch 2 may include a first spraying branch 21 and a second spraying branch 22, and a water pump 5 is arranged in the first spraying branch 21.

Where, a water outlet 11 of the water outlet device 1, the first spraying branch 21, the second spraying branch 22 and the nozzle 4 may be connected in sequence. A water outlet 11 of the water outlet device 1, the first spraying branch 21, the backflow branch 3, and a water inlet 12 of the water outlet device 1 may be connected in sequence.

Liquid may be extracted from the water outlet device through the water pump. Where, the water outlet device may be a water tank or a water net, the liquid may be water or coolant liquid. The pumped liquid may flow out of the nozzle through the first spraying branch and the second spraying branch. Alternatively, the liquid flows into the water outlet device again through the first spraying branch and the backflow branch.

Regarding the solenoid valves in the spray system, in this embodiment, the solenoid valves may be arranged in the form of a two-way solenoid valve or a three-way solenoid valve. Referring to the arrangement of the solenoid valve in the first spray system shown in FIG. 3, a first solenoid valve 61 may be arranged in the second spraying branch 22, a second solenoid valve 62 may be arranged in the backflow branch 3. Both the first solenoid valve 61 and the second solenoid valve 62 are two-way solenoid valves. The first solenoid valve 61 may control turning on and turning off of the second spraying branch 22, the second solenoid valve 62 may control turning-on and turning-off of the backflow branch 3.

Referring to the schematic diagram of the arrangement of the solenoid valves in the second spray system shown in FIG. 4, a third solenoid valve 63 may be disposed at the intersection point of the first spraying branch 21, the second spraying branch 22 and the backflow branch 3. Where, the third solenoid valve 63 is a three-way solenoid valve. It needs to be noted that the three-way solenoid valve has the function of switching between accesses and cannot turn off the accesses. That is, even if the three-way solenoid valve only has the following two conditions: the second spraying branch is turned on and the backflow branch is turned off, or the second spraying branch is turned off and the backflow branch is turned on, the second spraying branch and the backflow branch cannot be turned off completely, the second spraying branch and the backflow branch cannot be turned on simultaneously, too.

Therefore, in order to turn off the second spraying branch and the backflow branch simultaneously, in this embodiment, a switch module may be arranged in the water pump, the water pump is turned on or turned off through the switch module. If the water pump is turned off, even though the second spraying branch and the backflow branch cannot be turned off, liquid cannot flow through the second spraying branch and the backflow branch. That is, if the switch module is arranged in the water pump, none of the second spraying branch and the backflow branch is provided with the solenoid valve.

Alternatively, the second spraying branch and the backflow branch may be turned off simultaneously by arranging two-way solenoid valves in the second spraying branch and the backflow branch. For example, a fourth solenoid valve is arranged in the second spraying branch or a fifth solenoid valve is arranged in the backflow branch, if the switch module is not arranged in the water pump. Where, both the fourth solenoid valve and the fifth solenoid valve are two-way solenoid valves.

Referring to the schematic diagram of the arrangement of the solenoid valves in the third spraying system shown in FIG. 5, a fourth solenoid valve 64 may be arranged in the second spraying branch 22, and the fourth solenoid valve 64 may control the second spraying branch 22 to be turned off and turned on. In this condition, if the second spraying branch 22 and the backflow branch 3 need to be turned off simultaneously, the backflow branch 3 may be controlled to be turned off and the second spraying branch 22 may be controlled to be turned on through the third solenoid valve 63 first, then, the second spraying branch 22 is controlled to be turned off through the fourth solenoid valve 64.

Referring to the schematic diagram of the arrangement of the solenoid valves in the fourth spraying system shown in FIG. 6, a fifth solenoid valve 65 may be arranged in the backflow branch 3, and the fifth solenoid valve 65 may control turning off and turning on of the backflow branch 3. In this condition, if the second spraying branch 22 and the backflow branch 3 need to be turned off simultaneously, the backflow branch 3 may be controlled to be turned on and the second spraying branch 22 may be controlled to be turned off through the third solenoid valve 63, then, the backflow branch 3 is controlled to be turned off through the fifth solenoid valve 65.

According to the spraying system provided in the embodiments of the present disclosure, a purpose of controlling turning on and turning off of the spraying branch and the backflow branch through the solenoid valves may be achieved by arranging the two-way solenoid valve or the three-way solenoid valve in the spraying branch and the backflow branch, the spraying system has a low cost and it is convenient to implement the spraying system.

Additionally, with reference to the structural schematic diagram of another spraying system shown in FIG. 7, the spraying system may further include a detection module 7. The detection module 7 is configured to detect a startup-shutdown and a spraying mode of the spray system.

Additionally, as shown in FIG. 7, the spraying system may further include a control module 8. The control module 8 may be in communication connection with the detection module 7, and the control module 8 is connected to solenoid valves (i.e., the first solenoid valve 61 and the second solenoid valve 62) of the spraying system. The control module is configured to control turning on and turning off of the solenoid valves based on a detection mode.

The detection module and the control module may be arranged on the same circuit board, the detection module and the control module may be in communication connection. The control module is communicated with the solenoid valve and the water pump through wires, and controls power on and power off of the solenoid valve and the water pump through a relay mounted in the control module, and thereby controls the turning on and turning off states of the solenoid valve and the water pump. A floating ball valve is arranged in the water outlet device, when a liquid level is lower than a preset height, the floating ball valve is started to supply water into the water outlet device to ensure that the water outlet device is in a state of being filled with water. After the detection module detects a enable signal of the spraying system, whether the spraying system is in the intermittent spraying mode or in the continuous spraying mode is further determined.

The method for controlling the spraying system according to the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

A method for controlling a spraying system is provided in the embodiments of the present disclosure, this method is applicable to the spraying system provided in the aforesaid embodiment. Where, the spraying system in this embodiment may include a water outlet device (in this embodiment, a water tank is taken as an example, which is not repeatedly described here), a water pipe, a water pump, a solenoid valve, a nozzle, a heat exchanger, a detection module, and a control module. In all embodiments of the present disclosure, a water pipe branch where the nozzle is located is defined as the spraying branch, and a branch flowing back to the water tank is defined as the backflow branch.

Based on the above description, referring to the flow diagram of the method for controlling the spraying system shown in FIG. 8, the method for controlling the spraying system may include the following steps:

In a step of S802, a spraying mode of the spray system is determined.

The spraying mode of the spraying system may be input by a user through a button on an air conditioner, a remote controller of the air conditioner or an application program of a terminal device. The spraying system may determine the spraying mode of the spraying system through the detection module.

The determination of the spraying mode of the spraying system may include a continuous spraying mode or an intermittent spraying mode. The continuous spraying mode may be interpreted as liquid in the water tank continuously flows out of the nozzle, and the intermittent spraying mode may be interpreted as the liquid in the water tank intermittently flows out of the nozzle. The liquid in the water tank may be cooling water or water, different spraying times and intermittent times may be set in the intermittent spraying mode. For example, the spraying time is 10 seconds, the intermittent time is 6 seconds, it may be understood that the liquid flows out from the nozzle between for 0-10 seconds, the liquid stops flowing out of the nozzle for 10-16 seconds, etc.

In a step of S804, the spraying branch of the spraying system is controlled to be turned on, and the backflow branch of the spraying system is controlled to be turned off, such that the liquid in the water outlet device of the spraying system continuously flows out of the nozzle of the spraying system, if the spraying mode is the continuous spraying mode.

If the spraying mode is the continuous spraying mode, the spraying branch may be controlled to be turned on and the backflow branch is controlled to be turned off through the solenoid valve of the spraying system. Where, the number and the type of the solenoid valve of the spraying system are not limited, that is, the spraying system may include a plurality of solenoid valves, and each of the solenoid valves may be a two-way solenoid valve or a three-way solenoid valve, and the like.

If the spraying branch is turned on and the backflow branch is turned off, the liquid in the water tank of the spraying system may sequentially flow out of the nozzle of the spraying system through the spraying branch, and water in the spraying system cannot flow into the water inlet of the water tank from the water outlet of the water tank through the backflow branch in sequence, in this condition, the liquid in the water tank continuously flows out of the nozzle.

In a step of S806, the spraying branch is controlled to be turned on, the backflow branch is controlled to be turned off, or the spraying branch is controlled to be turned off and the backflow branch is controlled to be turned on, such that the liquid in the water outlet device intermittently flows out of the nozzle, in response to the spraying mode being the intermittent spraying mode.

If the spraying branch is turned off, the backflow branch is turned on, in this condition, the liquid in the water tank of the spraying system may sequentially flow into the water inlet of the water tank from the water outlet of the water tank through the backflow branch, the liquid in the water tank cannot sequentially flow out of the nozzle of the spraying system through the spraying branch. That is, the liquid in the water tank stops flowing out of the nozzle, and the liquid flows into the water inlet of the water tank from the water outlet of the water tank, such that the water supply pressure may be increased, and maintenance of continuous operation of the water pump is unnecessary.

Thus, in response to the spraying mode being the intermittent spraying mode, the spraying branch may be controlled to be turned on and the backflow branch may be controlled to be turned off through the solenoid valve, or alternatively, the spraying branch is controlled to be turned off, and the backflow branch is controlled to be turned on, so that the liquid in the water tank flows out of the nozzle intermittently.

According to the method for controlling the spraying system provided in the embodiment of the present disclosure, in response to the spraying mode being the intermittent spraying mode, the spraying branch is controlled to be turned on and the backflow branch is controlled to be turned off through the solenoid valve, or alternatively, the spraying branch is controlled to be turned off and the backflow branch is controlled to be turned on, so that the liquid in the water tank flows out of the nozzle intermittently. In this way, it may be guaranteed that intermittent spraying is achieved in the spraying system of the water pump through switching of the solenoid valve, and the water supply pressure is improved through the backflow branch. Thus, the water pump does not need to be turned on and turned off frequently, an occurrence of temperature rise in the pump would not be caused, the service life of the water pump may be prolonged, the damage to the water pump is avoided, and the user experience is improved.

Another method for controlling a spraying system provided in one embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

Another method for controlling the spraying system is provided in this embodiment. This method is implemented on the basis of the aforesaid embodiment, FIG. 9 illustrates a flow diagram of another method for controlling the spraying system, the method for controlling the spraying system in this embodiment may include the following steps:

In a step of S902, a spraying mode of the spraying system is determined.

The solenoid valve in this embodiment may have different arrangements, the solenoid valves in the spray system may be arranged according to at least one of the following approaches: a two-way solenoid valve is provided in the spraying branch and the backflow branch; a two-way solenoid valve is provided in the spraying branch, and a three-way solenoid valve is disposed at the intersection of the spraying branch and the backflow branch; or, a two-way solenoid valve is arranged in the backflow branch, and a three-way solenoid valve is arranged at the intersection of the spraying branch and the backflow branch.

In a step of S904, the spraying branch is turned on if the spraying mode is the continuous spraying mode; the water pump of the spraying system is controlled to start to operate after the spraying branch has been turned off for a preset first time.

First, two-way solenoid valves arranged in the spraying branch and the backflow branch are taken as an example. As shown in FIG. 3, the spraying system includes two-way solenoid valves, that is, the first solenoid valve and the second solenoid valve, the first solenoid valve and the second solenoid valve are in a normal turned-off state when they are powered off.

If the spraying mode is determined as the continuous spraying mode, referring to the schematic diagram of the control mode of the first continuous spraying mode shown in FIG. 10, the detection module may transmit a signal to the control module through a communication wire, and the control module controls the first solenoid valve to be turned on firstly.

In order to avoid or alleviate a water hammer phenomenon caused by violent change of waterway pressure which is caused due to the fact that the solenoid valve is not completely turned on and the water pump is in operation. After the first solenoid valve has been energized for a first time t1, the control module controls the water pump to be turned on, and coolant liquid is obtained from the water tank, such that the coolant liquid in the water pipe is sprayed onto the heat exchanger at the nozzle through the first solenoid valve to realize spray evaporation cooling. In the operation process of the entire continuous spraying mode, the second solenoid valve is in a turned-off state.

In this way, turning on the water pump after the first solenoid valve has been turned on for the first time may be realized by setting. Thus, the water hammer phenomenon caused by violent change of the waterway pressure which is caused due to the fact that the solenoid valve is not completely turned on and the water pump is in operation may be avoided or alleviated, and the service life of the water pump is prolonged.

After a stop spraying signal is obtained by the detection module, the signal is transmitted to the control module, the water pump is controlled to stop operation. For example, the stop spraying signal is obtained, and the water pump is controlled to stop operation based on the stop spraying signal. After the water pump stops operation for the first time, the spraying branch is turned off.

After the water pump stops operation for the first time T1, the first solenoid valve is turned off, and the operation of the spray system is terminated. After the system is selected, T1 is usually a constant, however, startup time and shutdown time of different waterway systems, the water pump and the solenoid valves are different, the value of T1 is variable, T1 may be in the range of 1 s≤T1≤4 s.

In a step of S906, in response to the spraying mode being the intermittent spraying mode, the spraying time and the stop spraying time of the intermittent spraying mode are determined. During the spraying time, the spraying branch is controlled to be turned on, and the backflow branch is controlled to be turned off. During the stop spraying time, the spraying branch is controlled to be turned off and the backflow branch is controlled to be turned on.

In response to the spraying mode being the intermittent spraying mode, detection parameters may be further compared with an intermittent spraying table preset in the circuit board to determine the intermittent spraying mode (i.e., the spraying time is Tx seconds, the stop spraying time is Ty seconds, and spraying operation is performed periodically according to the rule).

Referring to the schematic diagram of the control mode of the first intermittent spraying mode shown in FIG. 11, the detection module transmits a signal to the control module through the communication wire, the control module first controls the first solenoid valve to be turned on. After the first solenoid valve has been energized for the first time T1, the control module controls the water pump to be turned on, the coolant liquid is obtained from the water tank, and the coolant liquid in the water pipe is sprayed onto the heat exchanger at the nozzle through the first solenoid valve to realize a spray evaporation cooling.

When the solenoid valve starts to be switched, in order to avoid the water hammer phenomenon caused due to instability of waterway, and fatigue stress damage of the system, it needs to ensure that the solenoid valve is switched when the water pump has been in a stable operation state. Following steps may be performed: the backflow branch is turned on when switching from the spraying time to the stop spraying time and the operation time of the water pump is greater than a preset time threshold; after the backflow branch has been turned on for a second time, the spraying branch is turned off.

When the water pump is energized and the operation time of the water pump is greater than a preset time threshold (e.g., at least 5 seconds), the second solenoid valve is controlled to be turned on. In order to prevent the entire waterway from being turned off due to turning off of the first solenoid valve when the second solenoid valve is not turned on. After the second solenoid valve has been turned on for the second time T2, the first solenoid valve is controlled to be turned off, in this condition, the spraying operation is stopped, the coolant liquid returns to the water tank through the second solenoid valve to realize circulation of the coolant liquid. T2 may be in the range of 1 s≤T2≤3 s.

In addition, when switching from the stop spraying time to the spraying time, the spraying branch may be turned on; after the spraying branch has been turned on for the second time, the backflow branch is turned off.

After the first solenoid valve has been turned off for the Ty time, the first solenoid valve is turned on again. After the second time T2 is passed, the second solenoid valve is turned off, and the spray operation is performed. After the second solenoid valve has been turned off for Tx-T2 time, the second solenoid valve is turned on again, and the first solenoid valve is turned off after T2 time is passed. The aforesaid two steps are performed cyclically until a stop spraying signal is received.

In particular, in the process of the intermittent spraying mode, spraying operation may be stopped by performing the following steps: obtaining the stop spraying signal, and controlling the water pump to stop operation based on the stop spraying signal; maintaining turned-off states of the solenoid valves of the spraying branch and the backflow branch if the solenoid valves of the spraying branch and the backflow branch are both in the turned-off state; if the solenoid valve of the spraying branch or the backflow branch is in the turned on state, controlling the solenoid valve of the spraying branch or the backflow branch in the turned on state to be turned on for the second time, and then turning off the solenoid valve of the spraying branch or the backflow branch in the turned state.

After the detection module obtains the stop spraying signal, the signal is transmitted to the control module, the water pump is controlled to stop operation firstly. When the water pump is controlled to stop operation, whether the first solenoid valve and the second solenoid valve are in the turned on state are determined. If the first solenoid valve and the second solenoid valve are in the turned-off state, the turned-off state of the first solenoid valve and the second solenoid valve are kept unchanged. If the first solenoid valve and the second solenoid valve are in the turned on state, the solenoid valve is turned off after the turning on state of the solenoid valve is maintained for T2 time forcibly, and the spraying system is terminated. After the spraying system stops operation, the process returns to the initial detection program, and the next spraying enable signal is waited.

As shown in FIG. 5, in this embodiment, a two-way solenoid valve (i.e., the fourth solenoid valve) may also be arranged in the spraying branch, a three-way solenoid valve (i.e., the third solenoid valve) is arranged at the intersection of the spraying branch and the backflow branch. The spraying system in this embodiment differs from the first spraying system shown in FIG. 3 in that the two-way solenoid valve in the backflow branch is replaced with the three-way solenoid valve, the three-way solenoid valve is arranged between the water pump and the fourth solenoid valve and is located at a branch point. Where, a port A is in communication with the water pump through the water pipe, a port B is in communication with the backflow branch flowing back to the water tank, and a port C is in communication with the fourth solenoid valve through the water pipe.

As shown in FIG. 5, when the port A is communicated with the port C, the coolant liquid flows through the fourth solenoid valve and is sprayed onto the heat exchanger at the nozzle. In this condition, the ports A and B are in the turned-off state, and the coolant liquid cannot flow back into the water tank. When the port A is communicated with the three-way solenoid valve B, the coolant liquid flows back to the water tank through the backflow branch. In this condition, the ports A and C are in a turned-off state, and the coolant liquid cannot be sprayed onto the heat exchanger. In an initial state, both the water pump and the fourth solenoid valve are turned off, the port A and the port C of the third solenoid valve are communicated.

After the detection module detects a enable signal of the spraying system, whether the spraying system is the intermittent spraying mode or in the continuous spraying mode is further determined. If the spraying mode is determined as the continuous spraying mode, referring to the schematic diagram of the control method of the second continuous spraying mode shown in FIG. 12, the detection module transmits a signal to the control module through the communication wire, and the control module controls the fourth solenoid valve to be turned on firstly; after the first time T1 is passed, the water pump is turned on to perform the spraying operation. After the stop spraying signal is received, the water pump is controlled to be turned off, after the water pump has been turned off for the first time T1, the fourth solenoid valve is turned off, and spraying operation is stopped.

If the spraying mode is determined as the intermittent spraying mode, referring to the schematic diagram of the control method of the second intermittent spraying mode shown in FIG. 13, the detection module transmits a signal to the control module through the communication wire, and the control module controls the fourth solenoid valve to be turned on firstly. After the first time T1 is passed, the water pump is turned on to perform the spraying operation; and after the Tx time is passed, the third solenoid valve switches from a AC access to a AB access, the coolant liquid flows back to the water tank, and the spray cooling operation is stopped. After Ty time is passed, the third solenoid valve switches from the AB access to the AC access to perform the spray operation.

The aforesaid steps are executed periodically in order to realize the intermittent spraying. After receiving the stop spraying signal, the water pump is controlled to be turned off. After the water pump has been turned off for the first time T1, the fourth solenoid valve is turned off. If the third solenoid valve is in an AC access state, the current state is maintained unchanged. If the third solenoid valve is in an AB access state, the third solenoid valve is switched to the AC access. After the spraying system stops operation, the process returns to the initial detection program, and the next spraying enable signal is waited.

As shown in FIG. 6, in this embodiment, a two-way solenoid valve (i.e., the fifth solenoid valve) may also be arranged in the backflow branch, and a three-way solenoid valve (i.e., the third solenoid valve) is arranged at the intersection of the spraying branch and the backflow branch. Unlike the second spray system shown in FIG. 5, the two-way solenoid valve on the spraying branch is transferred to the backflow branch. In the initial state, both the water pump and the fifth solenoid valve are turned off, and the third solenoid valve is in a state in which the port A is communicated with the port B.

After the detection module detects the enable signal of the spraying system, whether the spraying system is in the intermittent spraying mode or in the continuous spraying mode is further determined. If the spraying mode is determined as the continuous spraying mode, referring to the schematic diagram of the control method of the third continuous spraying mode shown in FIG. 14, the detection module transmits a signal to the control module through the communication wire, and the control module controls the third solenoid valve to switch from the AB access to the AC access firstly. After the first time T1 is passed, the water pump is turned on to perform the spraying operation. After the stop spraying signal is received, the water pump is controlled to be turned off. After the water pump has been turned off for the first time T1, the third solenoid valve switches from the AC access to the AB access, the spraying operation is terminated.

If the spraying mode is determined as the intermittent spraying mode, referring to the schematic diagram of the control method of the third intermittent spraying mode shown in FIG. 15, the detection module transmits a signal to the control module through the communication wire, the control module first controls the third solenoid valve to switch from the AB access to the AC access firstly, and the fifth solenoid valve is turned on simultaneously. After the first time T1 is passed, the water pump is turned on to perform the spraying operation. After the Tx time is passed, the third solenoid valve switches from the AC access to the AB access, the coolant liquid flows back to the water tank, and the spray cooling operation is stopped. After the Ty time is passed, the third solenoid valve switches from the AB access to the AC access to perform the spraying operation. The aforesaid steps may be performed sequentially and periodically to achieve the intermittent spraying.

After the stop spraying signal is received, the water pump is controlled to be turned off. After the water pump has been turned off for the first time, if the third solenoid valve is in the AB access state, the current state of the third solenoid valve is maintained unchanged, and the fifth solenoid valve is turned off. If the third solenoid valve is in the AC access state, the third solenoid valve is switched to the AB access, and the fifth solenoid valve is turned off. After the spraying system stops operation, the process returns to the initial detection program, and the next spraying enable signal is waited.
