The present disclosure provides a purification dehumidifier 100.
Referring to
The housing 10 is provided with an air inlet 111, a dehumidified air outlet 113 and a purified air outlet 115. An air duct 11 connecting the air inlet 111, the dehumidified air outlet 113 and the purified air outlet 115 is formed in the housing 10.
The fan 90 is arranged in the air duct 11 to introduce air into the air duct 11 from the air inlet 111 and blow the air in the air duct 11 out from the dehumidified air outlet 113 and the purified air outlet 115.
The dehumidifier assembly 50 is arranged in the air duct 11 and corresponding to the dehumidified air outlet 113.
The purifier assembly 30 is arranged in the air duct 11 and corresponding to the purified air outlet 115.
In the present embodiment, the housing 10 is approximately cylindrical and an axis of the housing 10 is vertical. The air inlet 111, the dehumidified air outlet 113, and the purified air outlet 115 are all arranged on the side wall of the housing 10. Specifically, the dehumidified air outlet 113 is disposed opposite to the air inlet 111, and the purified air outlet 115 is also disposed opposite to the air inlet 111.
The dehumidifier assembly 50 includes a condenser 55, an evaporator 53, and a refrigerant circulation line. The condenser 55 and the evaporator 53 are connected to the refrigerant circulation line. The condenser 55 and the evaporator 53 are both arranged close to the dehumidified air outlet 113, and the evaporator 53 is closer to the dehumidified air outlet 113 than the condenser 55. The evaporator 53 is configured to cover the dehumidified air outlet 113. As such, the air flow entering the air duct 11 from the air inlet 111 can be blown out from the dehumidified air outlet 113 after being heated and warmed by the condenser 55 and condensed and dehumidified by the evaporator 53 in sequence, to complete a dehumidifying process. It should be appreciated that the refrigerant circulation line includes a compressor 51, a throttling device (not shown) and pipelines (not shown) for connecting various components. The compressor 51 compresses the refrigerant to form high-temperature gas. After the heat of the high-temperature gas is dissipated by the condenser 55, low-temperature liquid is formed by the throttling device. In the evaporator 53, the low-temperature liquid absorbs heat from the air and is evaporated, and then returns to the compressor 51 to complete a refrigerant circulation process.
The purifier assembly 30 includes a purification filter layer and a mounting assembly (not shown). The mounting assembly is configured to fix the purification filter layer in the housing 10 and makes the purification filter layer cover the purified air outlet 115. As such, the air flow entering the air duct 11 from the air inlet 111 can be filtered by the purification filter layer before being blown out from the purified air outlet 115 to complete the purifying process.
When the fan 90 operates regularly, the air outside the housing 10 enters the housing 10 from the air inlet 111. After circulating in the housing 10, some of the air is dehumidified by the dehumidifier assembly 50 to become dry air, and is discharged from the dehumidified air outlet 113. The other part of the air is purified by the purifier assembly 30 to become clean air, and is discharged from the purified air outlet 115. As such, the purification dehumidifier 100 simultaneously operates with dehumidification and air purification.
It should be appreciated that, according to the technical solution of the present disclosure, the air inlet 111, the dehumidified air outlet 113 and the purified air outlet 115 are arranged on the housing 10 of the purification dehumidifier 100. The dehumidifier assembly 50 is arranged corresponding to the dehumidified air outlet 113 and the purifier assembly 30 is arranged corresponding to the purified air outlet 115. A part of air entering the housing 10 from the air inlet 111 can be dehumidified by the dehumidifier assembly 50 before being changed into dry air and discharged from the dehumidified air outlet 113. The other part of air entering the housing 10 from the air inlet 111 can be purified by the purifier assembly 30 before being changed into clean air and discharged from the purified air outlet 115. Thus dehumidification and the air purification can be achieved by the purification dehumidifier 100. That is, the purification dehumidifier 100 with dehumidification and purification functions is provided.
As shown in
For example, a separate purification and/or a separate dehumidification may be provided. When air purification is needed, the purified air outlet 115 is opened through the air door assembly, and the dehumidified air outlet 113 is closed. The fan 90 starts and external air enters through the air inlet 111. Dust particles and impurities in the air are filtered through the purifier assembly 30, and then the air flow out through the purified air outlet 115, to complete the purification. When air dehumidification is needed, the dehumidified air outlet 113 is opened through the air door assembly, and the purified air outlet 115 is closed. The fan 90 starts, and external air enters through the air inlet 111, is dehumidified through the dehumidifier assembly 50, and then flows out through the dehumidified air outlet 113, to complete the dehumidification. When the purification and dehumidification are simultaneously needed, both the purified air outlet 115 and the dehumidified air outlet 113 are opened through the air door assembly, and outside air enters the air duct 11 through the air inlet 111 for purification and dehumidification, and then flows out through the purified air outlet 115 and the dehumidified air outlet 113.
Further, the air door assembly includes at least one air door structure 70 corresponding to the dehumidified air outlet 113 or the purified air outlet 115.
The air door structure 70 includes a driving member 71, a connection member 73 and at least two swing blades 75. The connection member 73 is connected with the driving member 71 and the swing blades 75. The driving member 71 is configured to drive the connection member 73 to move and drive the swing blades 75 to rotate. A gap may be formed between two adjacent swing blades 75 to open the dehumidified air outlet 113 or the purified air outlet 115; or, the two adjacent swing blades 75 abut each other to block the dehumidified air outlet 113 or the purified air outlet 115.
When the purified air outlet 115 and the dehumidified air outlet 113 are opened or closed, the air door structure 70 is correspondingly adopted. The driving member 71 drives the connection member 73 and drives the swing blades 75 to rotate, so that gaps are formed between adjacent swing blades 75, and air enters the air duct 11 from the gaps; or two adjacent swing blades 75 abut each other to block the path of air entering the air duct 11. As such, the air door structure 70 is relatively simple in nature, and the purified air outlet 115 and the dehumidified air outlet 113 can be opened or closed conveniently and quickly. In some embodiments, the purified air outlet 115 and the dehumidified air outlet 113 each correspond to one air door structure 70. The effect of independently opening or closing the purified air outlet 115 and the dehumidified air outlet 113 can be realized.
The air door structure 70 includes a plurality of swing blades 75 arranged in the housing 10, and each swing blade 75 is elongated and extends in the vertical direction. A plurality of swing blades 75 are arranged along the circumferential direction of the housing 10, and each adjacent two swing blades 75 can form an arc-shaped door body structure after being spliced, with no gap along the circumferential direction of the door body structure. In addition, both ends of the door structure are respectively provided with an annular partition 131. The upper end of the cylindrical structure abuts against the inner edge of the annular partition 131 located above, and the lower end of the door structure abuts against the inner edge of the annular partition 131 located below. When the driving member 71 drives each swing blade 75 to rotate, each adjacent two swing blades 75 are separated from each other to form a gap. The corresponding purified air outlet 115 and/or dehumidified air outlet 113 are in communication with the air duct 11 in the door body structure, and air can enter the air duct 11 through the purified air outlet 115 and/or dehumidified air outlet 113.
The air door assembly may include an air door structure 70 disposed corresponding to the dehumidified air outlet 113. As such, the air outlet modes of the purification dehumidifier 100 can include a combined mode with dehumidification and purification and a separate purification mode. Of course, the air door structure 70 can be arranged corresponding to the purified air outlet 115. As such, the air outlet modes of the purification dehumidifier 100 can include a combined mode with dehumidification and purification, and a separate dehumidification mode. In some embodiments, the air door assembly comprises two air door structures 70. One air door structure 70 is arranged corresponding to the dehumidified air outlet 113 and the other air door structure 70 is arranged corresponding to the purified air outlet 115. As such, the air outlet modes of the purification dehumidifier 100 can include a combined mode with dehumidification and purification, a separate dehumidification mode, and a separate purification mode.
As shown in
The inner wall of the housing 10 is provided with an annular partition 131, which can be provided with an arc-shaped slide rail 1311. Correspondingly, the gear rack 733 is also arranged in an arc shape, matching the arc-shaped slide rail 1311. The gear rack 733 is mounted on the arc-shaped slide rail 1311, and can relatively slide along the arc-shaped slide rail 1311. In addition, the inner teeth of the arc-shaped rack 733 are meshed with each second gear 735. Each second gear 735 is sleeved on the rotating shaft of a swing blade 75. Additionally, the outer teeth of the arc-shaped rack 733 are meshed with the first gear 731, and the first gear 731 is sleeved on the output shaft of the first drive motor 95.
When the driving member 71 operates, its output shaft drives the first gear 731 to rotate. The rotation of the first gear 731 drives the gear rack 733 to slide along the slide rail 1311. The sliding of the gear rack 733 drives each second gear 735 to rotate. The rotation of each second gear 735 drives one swing blade 75 to rotate, realizing splicing or separating of each adjacent two swing blades 75. As such, the synchronous rotation of the swing blades 75 is effectively realized, and the structure is simple and practical.
Further, a guiding inclined surface is provided at the joint of one swing blade 75 and the other adjacent swing blade 75.
As such, the guiding and buffering of the guiding inclined surface can not only reduce the wear at the joint of each adjacent two swing blades 75 and prolong the service life of the swing blades 75, but also improve the sealing effect at the joint of each adjacent two swing blades 75 by abutting the two guiding inclined surfaces and avoid air leakage.
The driving member 71 is a step motor. As the precision of each step of the step motor is between 3% and 5%, the error of one step will not accumulate to the next. The step motor has advanced position precision and movement repeatability.
As shown in
Specifically, the cross-flow fan includes a volute 91, an impeller 93 arranged in the volute 91, and a motor 95 driving the impeller 93 to rotate. The volute 91 is positioned in the housing 10 and fixed to the side wall of the housing 10. The motor 95 is fixed to the upper end of the housing 10. The volute 91 has an air inlet side 911 and an air outlet side 913. The air inlet side 911 is in communication with the air inlet 111, and the air outlet side 913 is in communication with the dehumidified air outlet 113 and the purified air outlet In addition, the impeller 93 is extended in the height direction of the housing 10, and the height of the air inlet 111 is matched with the height of the impeller 93.
As such, the air inlet area of the purification dehumidifier 100 can be effectively increased and the air resistance can be reduced, thereby greatly improving the purifying and dehumidifying capability and the purifying and dehumidifying efficiency of the purification dehumidifier 100. And the purifying and dehumidifying effects of the purification dehumidifier 100 are further effectively enhanced. In addition, the application of the cross-flow fan can also enable the air intake of the purification dehumidifier 100 more uniform, thus improving the dehumidification effect of the dehumidifier assembly 50 and the purification effect of the purifier assembly 30. Additionally, the air flow flows through the impeller 93 with two times of force that that of the blades. The wind force on the air outlet side 913 of the volute 91 can be more stabilized, thus improving the dehumidification and purification. In addition, the application of cross-flow fan may produce relatively less noise.
As shown in
Specifically, the housing 10 includes a cylinder 13 and an end cap 15 that covers the upper end of the cylinder 13. The peripheral wall of the cylinder 13 is formed with an air inlet 111, a dehumidified air outlet 113, and a purified air outlet 115. In some embodiments, the air inlet 111, the dehumidified air outlet 113, and the purified air outlet 115 are all in a grid shape formed by a plurality of small circular holes distributed at intervals. The purified air outlet 115 is located above the dehumidified air outlet 113, both of which are opposite to the air inlet 111.
Understandably, since the dehumidified air outlet 113 and the purified air outlet 115 are arranged at interval in the height direction of the housing 10, the dehumidified air outlet 113 and the purified air outlet 115 can respectively occupy the side wall surfaces at different height positions of the housing 10, thereby being beneficial to increasing the dehumidified air outlet area and the purified air outlet area. It may also increase the volumes of the condenser 55, the evaporator 53 and the purification filter layer, further greatly improving the dehumidification and purification capacity and efficiency, and improving the dehumidification and purification effects.
Further, the air inlet 111, the dehumidified air outlet 113, and the purified air outlet 115 are all distributed along the circumferential direction of the housing 10.
Specifically, the air inlet 111, the dehumidified air outlet 113, and the purified air outlet 115 are all distributed along the circumferential direction of the cylinder 13. As such, the dehumidifier assembly 50 correspondingly includes a condenser 55 and an evaporator 53 which are in an arc shape. The condenser 55 and the evaporator 53 are sequentially provided along the air outlet direction of the dehumidified air outlet 113. As such, the evaporator 53 is positioned outside the condenser 55 and covers the dehumidified air outlet 113. The purifier assembly 30 includes a purification filter layer with an arc shape, which covers the purified air outlet 115.
It can be appreciated that when the fan 90 operates, under the drive of the fan 90, a part of the air in the purification dehumidifier 100 changes into dry air after passing through the arc-shaped condenser 55 and evaporator 53, and the dry air diffuses into the room from the dehumidified air outlet 113. The dehumidified air outlet 113 is distributed along the circumferential direction of the housing 10, not only effectively increasing the volume of the condenser 55 and evaporator 53, but improving the dehumidification capacity, dehumidification efficiency and dehumidification effect of the purification dehumidifier 100. And the air outlet area of the dehumidified air outlet 113 is also increased, so that dehumidified air can fill the room more quickly, further improving the dehumidification effect of the purification dehumidifier 100. Additionally, another part of the air in the purification dehumidifier 100 is changed into clean air by the purified air outlet 115 after being acted by the arc shape purifying filter layer and diffused into the room. As such, the purified air outlet 115 is distributed along the circumferential direction of the housing 10, not only effectively increasing the volume of the purifying filter layer, but also improving the purifying capacity, the purifying efficiency and the purifying effect of the purification dehumidifier 100. The air outlet area of the purified air outlet 115 is also increased, and the purified air can fill the room more quickly, thereby further improving the purifying effect of the purification dehumidifier 100. In addition, the air inlet 111 being distributed along the circumferential direction of the housing 10 can further increase the air inlet area and reduce the air resistance, thereby further improving the purification and dehumidification capability of the purification dehumidifier 100 and improving its purification and dehumidification efficiency.
In addition, it can be appreciated that in other embodiments, the housing 10 can also be provided as a cavity structure with an oval or polygonal cross section.
Further, the purification filter layer includes an activated carbon filter layer and a high-efficiency air filter layer, which are sequentially provided along the air outlet direction of the purified air outlet 115. As such, the air blown out from the purified air outlet 115 can pass through the activated carbon filter layer and the high-efficiency air filter layer successively before being blown out, effectively improving the air purification effect.
It should be appreciated that, the activated carbon filter layer can utilize porous activated carbon to adsorb one or more substances in the air on its surface and remove them. The removed objects include soluble organic substances, microorganisms, viruses and a certain amount of heavy metals. It may also decolorize, deodorize and purify the air. The activated carbon lattice can form developed pores with different shapes and sizes, thus greatly increasing the specific surface area and improving the adsorption capacity.
High efficiency particulate air filter (HEPA) is mainly used to collect dust particles and various suspended substances smaller than 0.5 micrometer. The filter layer of the high efficiency air filter is featured that air can pass through, but fine particles is blocked. Its count transmittance for particles with particle diameter ≥0.1 micrometer is ≤0.001% (i.e., efficiency ≥99.999%), and it is the most effective filter medium for pollutants such as smoke, dust and bacteria. The filter layer of the high-efficiency air filter can be a PP filter paper, a glass fiber, a composite PP-PET filter paper, a meltblown polyester nonwoven fabric or a meltblown glass fiber, etc.
Therefore, through the filtration of the active carbon filter layer and the high-efficiency air filter layer, organic pollutants and particles in the air can be purified, thus improving the purification effect and the air quality.
It should be appreciated that the shape, size and arrangement of the condenser 55 and the evaporator 53 can match those of the dehumidified air outlet 113 to achieve the optimal dehumidification effect. Additionally, the shape, size and arrangement of the purification filter layer can match those of the purified air outlet 115 to achieve the optimal purification effect. In addition, both the condenser 55 and the evaporator 53 can be provided with a plurality of heat exchange fins to increase the heat exchange area and improve the heat exchange efficiency.
Referring further to
Further, the compressor 51 is located below the condenser 55 and the evaporator 53, and provided opposite to the water tank 59. The compressor 51 is arranged below the condenser 55 and the evaporator 53 to facilitate the communication of pipelines. Since both the water tank 59 and the compressor 51 are heavy components, the installation of the purification dehumidifier 100 can be more stable by arranging both the water tank 59 and the compressor 51 at the lower end of the housing 10. Additionally, arranging the water tank 59 opposite to the compressor 51 can save the arrangement space inside the housing 10, so that the overall structural layout of the purification dehumidifier 100 is more compact.
The purification dehumidifier 100 may further include a first air door assembly (not shown) and a second air door assembly (not shown), where the first air door assembly is provided corresponding to the purified air outlet 115 to open or close the air flow passage at the purified air outlet 115, while the second air door assembly is provided corresponding to the dehumidified air outlet 113 to open or close the air flow passage at the dehumidified air outlet 113. In addition, the purification dehumidifier 100 may also be provided with an air quality monitoring device, including a particle sensor, a humidity sensor, etc. The air quality monitoring device is electrically connected with the main controller, and when more dust in the air is detected, the main controller controls the first air door assembly to open the airflow channel at the purified air outlet 115 to purify indoor air. When the humidity in the air is detected high, the main controller controls the second air door assembly to open the air flow passage at the dehumidified air outlet 113 to dehumidify the air indoor. Of course, when more dust and moisture are simultaneously detected, the main controller controls the two air door assemblies to open the air flow passages at the purified air outlet 115 and the dehumidified air outlet 113 respectively to purify and dehumidify the air.
It can be appreciated that the purification dehumidifier 100 can also be a part of the smart home Internet of Things. For example, the purification dehumidifier 100 is provided with a signal transmission device which is wirelessly connected with a mobile terminal (e.g., smart phone, tablet computer, etc.), and the wireless connection mode can be WiFi, Bluetooth, infrared or 4G. Through the signal transmission device, the mobile terminal can receive monitoring data and working status of the purification dehumidifier 100. The mobile terminal can control the operation mode of the purification dehumidifier 100, and additionally, the purification dehumidifier 100 can also form an air quality report and send it to the mobile terminal for users to check.
The above are only some embodiments of the present disclosure and do not therefore constitute a limitation to the present disclosure. Any equivalent structure modification perceived by using the contents of the present specification and drawings, or directly or indirectly applied in other related technical fields, shall be included in the scope of the present application.
