The machine shell is provided with a first side wall with an air inlet formed in the upper portion, a second side wall without an air inlet and a top wall with an air outlet. An airflow channel communicated with the air inlet and the air outlet is defined at the upper part in the shell; a mounting cavity is defined in the machine shell on the side close to the second side wall, and the upper portion of the mounting cavity is connected with the rear portion of the airflow channel. The compressor is arranged in the mounting cavity, and part of the compressor is located in the airflow channel.

[0054] Figure 1 is a schematic view of a dehumidifier 10 according to one embodiment of the present application; Figure 2 is Figure 1 is another schematic view of the dehumidifier 10 shown; Figure 3 is Figure 1 is a sectional schematic view of the dehumidifier 10 shown.

[0055] The present embodiment provides a dehumidifier 10, which includes a casing 11 and a compressor 12, and generally also includes a heat exchanger group 13, a water tank 14, an electrical box 15, an axial flow fan 16 and the like. Wherein the casing 11 is provided with an air inlet 11A and an air outlet 11B, the heat exchanger group 13 is arranged in the casing 11 and includes an evaporator and a condenser, and the fan is arranged in the casing 11 and causes the air to flow through the evaporator and the condenser in sequence after entering the casing 11 from the air inlet 11A, and then blows out from the air outlet 11B.

[0056] Since the surface temperature of the evaporator is lower than the dew point temperature of the air, the water vapor in the air condenses on the surface of the evaporator and flows into the water tank 14, thereby achieving the purpose of reducing the humidity of the air. The air flowing through the evaporator is also reduced in temperature while reducing the humidity. These air is then passed through the condenser, heated and discharged from the casing 11 through the air outlet 11B, so that the outlet air temperature of the dehumidifier 10 is close to the inlet air temperature, and the temperature of the ambient air is not significantly affected while dehumidifying.

[0057] The heat exchanger assembly 13 is usually located in the upper part of the casing 11, while the water tank 14 is located in the lower part of the casing 11, so that the condensate formed on the surface of the evaporator flows downward under its own gravity and eventually flows into the water tank 14. Therefore, the air inlet 11A of the dehumidifier 10 is also opened in the upper part of the side wall of the casing 11.

[0058] refer to Figure 1 , Figure 2 and Figure 3 As shown, the dehumidifier 10 of this embodiment has a casing 11 with a first side wall 111 having an air inlet 11A at the top, a second side wall 112 without an air inlet 11A, and a top wall 113 with an air outlet 11B. Figure 1 and Figure 2 In the illustrated embodiment, the housing 11 is designed as a cuboid and has three first sidewalls 111 and one second sidewall 112. The second sidewall 112, which does not have an air inlet 11A, can typically serve as the rear sidewall of the dehumidifier 10 so that the dehumidifier 10 can be placed against a wall. The other sidewalls of the housing 11 serve as the first sidewalls 111, and each surface has an air inlet 11A to increase the air intake of the dehumidifier 10 and improve dehumidification efficiency. In some alternative embodiments, the second sidewall 112 can be detachable relative to other parts of the housing 11 to facilitate the assembly and maintenance of the dehumidifier 10.

[0059] The design of the air outlet 11B on the top wall 113 reduces interference between the air intake and exhaust of the dehumidifier 10, thereby improving the overall airflow efficiency of the environment. In some other embodiments, the casing 11 may also be designed as a triangular prism, hexagonal prism, or other shapes, and has a varying number of first sidewalls 111 and a second sidewall 112, which is not limited here.

[0060] refer to Figure 1 As shown, the air inlet 11A of the dehumidifier 10 can be divided into multiple smaller ventilation holes by a mesh grille to prevent foreign objects from being sucked into the dehumidifier 10.

[0061] Figure 3 The diagram illustrates a vertical cross-section of the dehumidifier 10 in the front-to-back direction. (Reference) Figure 3 As shown, the upper part of the housing 11 defines an airflow channel 10A that connects the air inlet 11A and the air outlet 11B; and the housing 11 also defines a mounting cavity 10B on the side near the second side wall 112, the upper part of the mounting cavity 10B being connected to the rear part of the airflow channel 10A. The compressor 12 is disposed in the mounting cavity 10B, and a portion of the compressor 12 is located within the airflow channel 10A.

[0062] The air inlet 11A of the dehumidifier 10 of the present embodiment is formed in the upper portion of the first side wall 111 of the casing 11, and the air outlet 11B is formed in the top wall 113 of the casing 11. Therefore, the air flows into the casing 11 from the air inlet 11A in the horizontal direction, and flows out of the casing 11 from the air outlet 11B in the vertical direction, so that the upper portion of the interior of the casing 11 becomes the air flow passage 10A for the air flow. Meanwhile, the interior of the casing 11 is also defined as the installation cavity 10B on the side close to the second side wall 112 where the air inlet 11A is not formed, and the installation cavity 10B is in communication with the air flow passage 10A. It can be understood that, as shown in Figure 3 the air flow passage 10A is the region that is horizontally opposite to the air inlet 11A of the casing 11 or vertically opposite to the air outlet 11B of the casing 11, and the installation cavity 10B is the region that is close to the second side wall 112 and is not divided between the top wall 113 and the bottom plate of the casing 11. Therefore, when the upper portion of the installation cavity 10B is connected to the rear portion of the air flow passage 10A as shown in Figure 3 the installation cavity 10B and the air flow passage 10A can partially coincide.

[0063] On this basis, the height of the compressor 12 of the present embodiment is higher than the lower end of the air inlet 11A, so that a part of the compressor 12 can be located in the air flow passage 10A. When the air flow enters the casing 11 from the air inlet 11A on the first side wall 111, part of the air flow can flow in the air flow passage 10A on the side close to the second side wall 112 and pass through the compressor 12, so as to solve the heat dissipation problem of the compressor 12.

[0064] Referring to Figure 3 the lower portion of the interior of the casing 11 is also defined as the water tank accommodating cavity 10C. The dehumidifier 10 further comprises the heat exchanger group 13 and the water tank 14. The heat exchanger group 13 is arranged in the air flow passage 10A, so that the air entering the casing 11 from the air inlet 11A passes through the heat exchanger group 13 and is blown out from the air outlet 11B. The water tank 14 is arranged in the water tank accommodating cavity 10C and is used to collect the condensed water from the heat exchanger group 13.

[0065] In some optional embodiments, the casing 11 further has a bottom plate 114, and a support frame 115 arranged below the heat exchanger group 13. The support frame 115 has a rear wall that separates the installation cavity 10B from the water tank accommodating cavity 10C.

[0066] The rear wall of the support frame 115 separates the installation cavity 10B from the water tank accommodating cavity 10C in front and back, and the upper part of the support frame 115 also separates the air flow channel 10A from the water tank accommodating cavity 10C in up and down. The support frame 115 is used to support the heat exchanger group 13, and the support frame 115 can form a water collecting groove on the surface in contact with the heat exchanger group 13 to guide the condensed water from the heat exchanger group 13. In some alternative embodiments, the water tank accommodating cavity 10C can form an opening on a first side wall 111 of the cabinet 11 so that the water tank 14 can be pullably arranged. It can be understood that the support frame 115, the first side wall 111 and the bottom plate 114 of the cabinet 11 jointly define the water tank accommodating cavity 10C.

[0067] Figure 4 is Figure 1 a schematic top view of the inside of the dehumidifier 10.

[0068] Referring to Figure 4 In some alternative embodiments, the compressor 12 is arranged at the middle of the bottom plate 114 close to the second side wall 112. The middle of the rear wall of the support frame 115 is recessed away from the second side wall 112 to avoid the compressor 12.

[0069] Since the compressor 12 is arranged in the installation cavity 10B communicating with the air flow channel 10A in the present embodiment, the middle of the rear wall of the support frame 115 is recessed away from the second side wall 112, so that the air flow in part of the air flow channel 10A can drive the air flow between the rear wall of the support frame 115 and the compressor 12, thereby improving the heat dissipation efficiency of the lower part of the compressor 12. At the same time, it also avoids the problem that the support frame 115 is heated for a long time due to the close distance between the support frame 115 and the compressor 12, thereby accelerating the aging of the support frame 115.

[0070] In some alternative embodiments, the cabinet 11 has a plurality of first side walls 111 and a second side wall 112. The heat exchanger group 13 is arranged along the inner side of the plurality of first side walls 111; and the side surface of the heat exchanger group 13 is close to the air inlet 11A on the plurality of first side walls 111, and the two end parts are close to the second side wall 112.

[0071] Referring to Figure 4As shown, the heat exchanger assembly 13 is bent along the inner side of multiple first sidewalls 111. Since the housing 11 in this embodiment is cuboid, the heat exchanger assembly 13 is U-shaped. This allows the side surface of the heat exchanger assembly 13 to be as close as possible to the air inlets 11AA on the multiple first sidewalls 111, thereby increasing the facing area between the air inlets 11AA and the heat exchanger assembly 13, and allowing the air entering the housing 11 to contact the heat exchanger assembly 13 more fully. The side surface of the heat exchanger assembly 13 is close to the air inlets 11AA on the multiple first sidewalls 111, and the two ends are close to the second sidewall 112, so that after the air enters the housing 11 from the air inlets 11AA, it passes through the heat exchanger assembly 13 and is blown out from the air outlet 11BB.

[0072] Heat exchanger group 13 Figure 4 The arrangement is multi-layered, with at least one layer each for the evaporator and the condenser. The evaporator is located on the side closest to the first sidewall 111, while the condenser is located on the side relatively far from the first sidewall 111.

[0073] It is understandable that when the casing 11 is different Figure 1 Other shapes of the embodiments, or the extension direction of the first sidewall 111 of the housing 11, may differ. Figure 4 In the embodiment, the bending shape of the heat exchanger assembly 13 may also be different. Figure 4 Example.

[0074] refer to Figure 2 and Figure 4 As shown, in some alternative embodiments, the dehumidifier 10 also includes an electrical enclosure 15. The electrical enclosure 15 is vertically disposed between one end of the heat exchanger assembly 13 and the second sidewall 112.

[0075] Figure 5 yes Figure 1 A schematic diagram of the electrical box 15 of the dehumidifier 10 shown.

[0076] refer to Figure 5 As shown, the electrical box 15 of this embodiment includes a box body 151 and a cover 152, defining an openable and closable accommodating space. The electrical box 15 can be used to house and protect electrical components such as the computer board 153 to prevent them from coming into contact with external moisture. The capacitor 125 of the compressor 12 can also be housed inside the electrical box 15.

[0077] Figure 6 yes Figure 1 A schematic diagram of the compressor 12 of the dehumidifier 10 shown.

[0078] refer to Figure 6As shown, in some alternative embodiments, the compressor 12 comprises a base 121, a main body 122 and a terminal portion 123. The base 121 is fixed on the bottom plate 114. The main body 122 is arranged on the base 121. The terminal portion 123 is arranged on the main body 122. The main body 122 is at least partially located in the air flow passage 10A.

[0079] The compressor 12 generally further comprises a gas-liquid separator 124 arranged on the main body 122. The compressor 12 pumps refrigerant into the heat exchanger group 13, and the refrigerant flows through the condenser and the evaporator in sequence and then passes through the gas-liquid separator 124 to return to the compressor 12. Therefore, the gas-liquid separator 124 is generally arranged on the side of the compressor 12 away from the electrical box 15, so as to be connected to the end of the heat exchanger group 13 not provided with the electrical box 15 through the refrigerant pipe. The refrigerant pipe connecting the compressor 12 and the heat exchanger group 13 is omitted in the figure.

[0080] Since the heat dissipation area of the compressor 12 is mainly the main body 122 through which the refrigerant flows, the main body 122 of the compressor 12 in the present embodiment is at least partially located in the air flow passage 10A, so as to better utilize the air flow in the air flow passage 10A for heat dissipation.

[0081] In some alternative embodiments, the dehumidifier 10 further comprises an axial flow fan 16. The axial flow fan 16 is arranged at the air outlet 11B, and is used to promote the formation of the air flow entering the casing 11 from the air inlet 11A and blowing out from the air outlet 11B. The dehumidifier 10 in the present embodiment is provided with the axial flow fan 16 at the air outlet 11B to promote the air flow, and the axial flow fan 16 can uniformly suck in air from the lateral periphery inside the casing 11, so as to better improve the efficiency of air exchange and dehumidification in cooperation with the bent heat exchanger group 13 and the air inlets 11A opened on the plurality of first side walls 111 without increasing the height of the dehumidifier 10.

[0082] The axial flow fan 16 comprises a fan cover 161 and a fan body 162. The fan cover 161 is arranged at the air outlet 11B, and the fan cover 161 is formed with a ventilation grid portion 1611 for the air flow to pass through. The fan body 162 is arranged below the fan cover 161, and is used to promote the formation of the air flow passing through the ventilation grid portion 1611.

[0083] The ventilation grid portion 1611 is opposite to the fan blades on the fan body 162 in an up-down direction and in a ring shape, so that the fan body 162 promotes the air flow to flow upwards and out of the casing 11 after entering the casing 11 from the air inlets 11A opened on the plurality of first side walls 111 of the casing 11 in a lateral direction and passing through the heat exchanger group 13.

[0084] In addition, the axial fan 16 further comprises a driving motor 163 arranged between the fan housing 161 and the fan body 162 for driving the fan body 162 to rotate.

[0085] Figure 4 The projection position of the ventilation grid part 1611 on the water surface is also schematically shown by a dashed line in the figure, wherein the outer edge of the projection of the ventilation grid part 1611 is represented by a dashed line 161a, and the inner edge of the projection of the ventilation grid part 1611 is represented by a dashed line 161b. In some alternative embodiments, the projection of the ventilation grid part 1611 on the horizontal plane coincides with the projection of the main body part 122 on the horizontal plane. The rotation axis of the fan body 162 does not coincide with the projection of the main body part 122 on the horizontal plane.

[0086] When the air flow flows in the air flow channel 10A in the casing 11, the air flow speed in the area directly below the ventilation grid part 1611, i.e., the area coinciding with the projection of the ventilation grid part 1611 on the horizontal plane, is faster. Therefore, the present embodiment makes the main body part 122 of the compressor 12 coincide with the projection of the ventilation grid part 1611 on the horizontal plane, thereby effectively improving the heat dissipation efficiency of the compressor 12. Meanwhile, the air flow speed in the area inside the inner ring of the ventilation grid part 1611 is slower because the area does not have the air outlet 11B. Therefore, the present embodiment also makes the rotation axis of the fan body 162 not coincide with the projection of the main body part 122 of the compressor 12 on the water surface, so as to avoid the compressor 12 being too close to the middle part of the ventilation grid part 1611 and causing the heat dissipation efficiency to decrease.

[0087] In some alternative embodiments, the fan housing 161 further extends downward from the outer side of the ventilation grid part 1611 to form a flow guide wall part 1612, and the lower end of the flow guide wall part 1612 is higher than the compressor 12.

[0088] The height of the compressor 12 is generally not close to the height of the installation cavity 10B. Therefore, when the compressor 12 is arranged on the bottom plate 114 of the casing 11, the top end of the compressor 12 can be far away from the air outlet 11B on the top wall 113. In order to enhance the air flow speed in the air flow channel 10A close to the compressor 12, the fan housing 161 of the present embodiment further extends downward from the outer side of the ventilation grid part 1611 to form the flow guide wall part 1612, so as to reduce the height of the air flow when the air flow converges in the air flow channel 10A toward the air outlet 11B, and enable more air flow to flow through the upper part of the compressor 12, thereby improving the heat dissipation efficiency of the compressor 12.

[0089] At this point, those skilled in the art should recognize that, although the present utility model has been shown and described in detail herein through a plurality of exemplary embodiments, many other variants or modifications conforming to the principles of the present utility model can still be directly determined or deduced from the content disclosed by the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and recognized as covering all these other variants or modifications.
