The present invention relates to a mobile air conditioner and, more particularly, to a mobile air conditioner with a circulation device.
A conventional mobile air conditioning apparatus 1 in accordance with the prior art shown in
Another conventional mobile air conditioner was disclosed in the applicant's Chinese Patent application serial No. 201621102787.3, Japanese Patent application serial No. 2016-5559, German Patent application serial No. 20201606472 and Australian Patent application serial No. 2017100009. Such a mobile air conditioner comprises a circulation device for collecting hot wasted air and wasted water produced by the mobile air conditioner. The hot wasted air from an air blower is introduced by an air drain pipe into the bottom of the circulation device. The wasted water is collected in the circulation device to cool and reduce the temperature of the hot wasted air. However, when the hot wasted air is delivered from the air blower, the air blower does not apply any pressure to force the hot wasted air, so that the hot wasted air cannot be introduced smoothly into the wasted water of the circulation device.
The primary objective of the present invention is to provide a mobile air conditioner with a circulation device having environmental protection and energy-saving.
In accordance with the present invention, there is provided a mobile air conditioner comprising a circulation device for collecting hot wasted air and wasted water produced by the mobile air conditioner. The circulation device includes a water tank and a radiating pipe placed on a bottom of the water tank. The radiating pipe has a first end connected to an air blower and a second end connected to an air draining device. The air draining device has an outlet provided with an active carbon for filtering impurities in the hot wasted air. The radiating pipe is located under a water level of the water tank. The second end of the radiating pipe is located above the water level of the water tank. The hot wasted air flows from the air blower into the radiating pipe. The wasted water is collected in the water tank. The wasted water cools and returns the hot wasted air, and the active carbon purifies the hot wasted air, to release a clean air.
Preferably, the air draining device has a top provided with an oblique cooling plate.
Preferably, the circulation device further includes a plurality of heatsink plates surrounding the radiating pipe.
Preferably, the radiating pipe has different length and shapes without affecting flowing movement of the hot wasted air.
Preferably, the circulation device includes at least one radiating pipe.
The mobile air conditioner in accordance with the present invention includes four features as follows:
(1) living: the mobile air conditioner produces clean air which is the living source of the mankind;
(2) delivery: the mobile air conditioner forms a circulation by operation of the compressor to produce cold air, wasted water and hot wasted air;
(3) guidance: the wasted water and the hot wasted air are guided into the circulation device which cooperates the active carbon to cool and purify the hot wasted air; and
(4) burning: the hot wasted air is cooled, purified and returned to release the clean air.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The design point of the present invention is in that, the mobile air conditioner 2 further comprises a circulation device 3. The circulation device 3 includes a water tank 31 and a radiating pipe 32 mounted in the water tank 31. The water tank 31 has a top provided with an opening 310. The radiating pipe 32 has a first end provided with an entrance 321 connected to an air outlet 50 of an air blower 5 and a second end connected to an air draining device 322. The hot wasted air produced by the mobile air conditioner 2 passes through the entrance 321 into the radiating pipe 32. The air draining device 322 has an outlet provided with an active carbon 4.
The air draining device 322 is provided with an oblique cooling plate 3220 that is inclined downward. The wasted water (cold water) produced by the mobile air conditioner 2 passes through a drain pipe, drops onto the cooling plate 3220 and is guided by the cooling plate 3220 into the water tank 31, so that the wasted water is collected in the water tank 31. The water tank 31 has a determined water level. The radiating pipe 32 has a bottom placed on a bottom of the water tank 31 and is immersed into the water of the water tank 31.
In operation, when the mobile air conditioner 2 is started, the refrigerator is compressed by the compressor to have high temperature and high pressure. Then, the refrigerator is condensed into a liquid by the condenser. Then, the refrigerator is evaporated by the evaporator to achieve a heat-absorbing effect, and to deliver a cold air to cool down the indoor room gradually. At this time, hot wasted air and wasted water are produced during operation of the mobile air conditioner 2. The circulation device 3 is used to collect, filter, purify and return the hot wasted air and the wasted water produced by the mobile air conditioner 2. The wasted water passes through the drain pipe, drops onto the cooling plate 3220 and is guided by the cooling plate 3220 into the water tank 31, so that the wasted water is collected in the water tank 31 of the circulation device 3. The hot wasted air from the air blower 5 is delivered through the radiating pipe 32 of the circulation device 3 so that the hot wasted air is cooled by the radiating pipe 32. When the hot wasted air flows in the radiating pipe 32 to reach the bottom of the water tank 31, the hot wasted air is cooled by the radiating pipe 32 and by the water in the water tank 31. Then, the hot wasted air continues to flow through the radiating pipe 32 and is cooled by the radiating pipe 32 successively. Then, the hot wasted air is drained from the radiating pipe 32 into the air draining device 322. Then, the hot wasted air is filtered by the active carbon 4 and is revived into a clean air under a normal temperature. Then, the clean air is drained from the air draining device 322. The active carbon 4 filters impurities contained in the hot wasted air and drains the clean air, thereby preventing the hot wasted air from causing an air pollution.
It is appreciated that, the wasted water is produced successively during operation of the mobile air conditioner 2 so that the circulation device 3 does not need to replenish the water. In addition, the wasted water is evaporated by the hot wasted air so that the circulation device 3 does not need to drain the water. Thus, the circulation device 3 can reduce the temperature of the air, clean the air and replenish the water to form a cycle circulation so as to recycle the hot wasted air and the wasted water produced by the mobile air conditioner 2. In addition, the hot wasted air directly evaporates the wasted water, so that the water in the water tank 31 will not spill outward under normal operation. Thus, the user only needs to replace the active carbon 4 and to clean the circulation device 3 during a period of time.
The hot wasted air is drained from the air blower 5 into the radiating pipe 32 by operation of a fan, so that the air blower 5 does not apply any pressure to drive the hot wasted air. The radiating pipe 32 is used to guide the hot wasted air from the air blower 5 smoothly. The radiating pipe 32 is made of material, such as metal, with greater heat dissipation effect. Preferably, the radiating pipe 32 is made of aluminum. When the hot wasted air flows in the radiating pipe 32, the temperature of the hot wasted air is reduced successively by the radiating pipe 32. The radiating pipe 32 is immersed into the water of the water tank 31, so that when the hot wasted air reaches the bottom of the water tank 31, the hot wasted air is cooled quickly by the water of the water tank 31.
The cooling plate 3220 is located under the drain pipe and above the water tank 31. In such a manner, the wasted water from the drain pipe drops onto the cooling plate 3220 successively and is guided downward by the inclined design of the cooling plate 3220 into the water tank 31. Thus, when the wasted air flows from the radiating pipe 32 into the air draining device 322, the wasted air is cooled again by the cooling plate 3220.
Referring to
Preferably, sensing devices (not shown) are mounted on upper end lower ends of the water tank 31 to detect the water level in the water tank 31 so that when the sensing devices detects that the water level is too high or too low, the sensing devices transmit a warning signal to the user or directly stops operation of the mobile air conditioner 2.
In practice, the length of the radiating pipe 32 is increased to enhance the heat dissipation effect of the radiating pipe 32. Alternatively, the surface area of the radiating pipe 32 is increased to enhance the heat dissipation effect of the radiating pipe 32. Alternatively, the circulation device 3 includes a plurality of radiating pipes 32 to enhance the heat dissipation effect.
Another design point of the present invention is in that, when the hot wasted air is cooled, filtered and returned to a clean air under a normal temperature, the wasted water is evaporated by the hot wasted air, so that the clean air contains moisture volatilized by the water, to prevent the user's skin from being dried, and prevent the user from feeling uncomfortable.
Referring to
In conclusion, the mobile air conditioner 2 in accordance with the present invention has the following features:
(1) high efficiency: By the procedures of living, delivery, guidance and burning, the inner temperature of the mobile air conditioner 2 is reduced, thereby greatly enhancing the air conditioning effect.
(2) clean: The circulation device 3 returns the hot wasted air, and the active carbon 4 filters and purifies the hot wasted air, so as to produce the clean air.
(3) no installation: The mobile air conditioner 2 does not need to mount lines for draining the hot wasted air and the wasted water.
(4) convenience: The hot wasted air directly evaporates the wasted water, to prevent from incurring a water overflow problem.
(5) environmental protection: The circulation device 3 transfers two main pollution sources, including the hot wasted air and the wasted water, into the clean air that is necessary for the mankind.
(6) comfort: The water in the water tank 31 is evaporated to provide a humidifying effect to the indoor room.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
