[0042] Figure 1 is a schematic view of a dehumidifier 10 according to one embodiment of the present utility model; Figure 2 is a schematic top view of the inside of the dehumidifier 10 according to one embodiment of the present utility model.

[0043] Reference Figure 1 and Figure 2 As shown in the drawings, the present embodiment provides a dehumidifier 10, which includes a casing 12, a heat exchanger set 14 and an electrical box 16, and generally also includes a water tank, a fan, a compressor, a throttling device, a temperature sensor and the like components (not shown in the drawings). The casing 12 is provided with an air inlet 12A and an air outlet 12B, the heat exchanger set 14 is arranged inside the casing 12 and includes an evaporator and a condenser, and the fan is arranged inside the casing 12 and causes the air to flow through the evaporator and the condenser in sequence after entering the casing 12 from the air inlet 12A, and then is blown out of the casing 12 from the air outlet 12B.

[0044] 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, thereby achieving the purpose of reducing the humidity of the air. The air flowing through the evaporator is also cooled in the process of reducing the humidity. These air is then heated by the condenser and discharged from the casing 12 through the air outlet 12B, 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 during dehumidification.

[0045] The heat exchanger set 14 is usually arranged at the upper part inside the casing 12, and the water tank is arranged at the lower part inside the casing 12, so that the condensed water formed on the surface of the evaporator flows downward under the action of its own gravity and finally flows into the water tank, and therefore the air inlet 12A of the dehumidifier 10 is also arranged at the upper part of the side wall of the casing 12.

[0046] The casing 12 of the dehumidifier 10 of the embodiment has a plurality of first side walls 121 with air inlets 12A and a second side wall 122 without air inlets 12A, and has a top wall 123 with an air outlet 12B. The casing 12 is generally designed as a cuboid, and has three first side walls 121 and one second side wall 122. The second side wall 122 without air inlets 12A can be used as the back side wall of the dehumidifier 10, so that the dehumidifier 10 can be placed against a wall. The other side walls of the casing 12 are used as the first side walls 121, and the surfaces of the first side walls 121 are provided with air inlets 12A, so as to increase the air intake of the dehumidifier 10 and improve the dehumidification efficiency. The top wall 123 is provided with the air outlet 12B, so that the interference between the air intake and the air outlet of the dehumidifier 10 is small, thereby improving the overall flow efficiency of the ambient air. In addition, the casing 12 can also be designed as a triangular prism, a hexagonal prism or other shapes, and has a different number of first side walls 121 and one second side wall 122, which are not limited herein.

[0047] Referring to Figure 1 As shown in the figure, the air inlets 12A of the dehumidifier 10 can be divided into a plurality of smaller ventilation holes by a mesh grille, so as to prevent foreign matters from being sucked into the dehumidifier 10.

[0048] Referring to Figure 2 As shown in the figure, the heat exchanger group 14 is arranged in a U shape in the casing 12, and the U shape here refers to the cross section of the heat exchanger group 14 being in a U shape, so that the side surface of the heat exchanger group 14 can be arranged as close as possible to the air inlets 12A on the plurality of first side walls 121, so as to increase the facing area of the air inlets 12A and the heat exchanger group 14, and make the air entering the casing 12 more fully contact the heat exchanger group 14. Figure 2 As shown in the figure, the heat exchanger group 14 is arranged in multiple layers, and each of the evaporator and the condenser has at least one layer. The evaporator is arranged on the side closest to the first side wall 121, and the condenser is arranged on the side farthest from the first side wall 121.

[0049] The electric appliance box 16 itself has a small heat generation but has a heat dissipation problem. In order to avoid the electric appliance box 16 from accumulating heat seriously, the two end portions of the heat exchanger group 14 of the dehumidifier 10 of the embodiment are at least partially spaced from the second side wall 122, and the electric appliance box 16 is arranged between the end portion of the heat exchanger group 14 and the second side wall 122. Since the electric appliance box 16 is arranged at the end portion of the heat exchanger group 14 close to the air flow path, the air around the electric appliance box 16 can be driven to flow, so that the electric appliance box 16 can avoid accumulating heat seriously, and the heat dissipation efficiency of the electric appliance box 16 is improved.

[0050] Figure 3 is a schematic exploded view of the dehumidifier 10 according to an embodiment of the utility model.

[0051] Referring to Figure 3As shown, in some alternative embodiments, the second side wall 122 is detachably arranged relative to the plurality of first side walls 121. As the rear wall of the casing 12 of the dehumidifier 10 is not provided with the air inlet 12A, the second side wall 122 can be arranged to be detachable relative to the other side walls, so as to facilitate the installation and maintenance of the dehumidifier 10. The other side walls of the casing 12, including the first side walls 121 and the top wall 123, can be integrally formed, so as to improve the appearance and enhance the strength.

[0052] In some alternative embodiments, the electrical box 16 can be in the shape of a long strip. The two ends of the heat exchanger group 14 include a first end and a second end. The first end of the heat exchanger group 14 is spaced apart from the second side wall 122, and the electrical box 16 is vertically arranged between the first end of the heat exchanger group 14 and the second side wall 122.

[0053] The heat exchanger group 14 described in the present embodiment includes both the fin portions arranged in a spaced apart manner and the refrigerant coil portions penetrating through the fins, but does not include the refrigerant connection pipes connecting the heat exchanger group 14 with the compressor. The ends of the heat exchanger group 14 of the present embodiment are located outside the fin portions and form the bent refrigerant coil portions. The first end and the second end of the heat exchanger group 14 are not distinguished as left or right, i.e., the first end can be close to the left side or the right side of the dehumidifier 10 in the transverse direction. The first end of the heat exchanger group 14 is spaced apart from the second side wall 122, so that at least a portion of the electrical box 16 can be located between the first end of the heat exchanger group 14 and the second side wall 122. The second end of the heat exchanger group 14 can be connected with the compressor through the refrigerant connection pipes.

[0054] In other alternative embodiments, the upper portions of the first end and the second end of the heat exchanger group 14 can be spaced apart from the second side wall 122, respectively, and the electrical box 16 can be horizontally arranged in the casing 12, with the two ends of the electrical box 16 located between the upper portions of the first end and the second end of the heat exchanger group 14 and the second side wall 122, respectively.

[0055] Figure 4 is Figure 3 The schematic exploded view of the electrical box 16 of the dehumidifier 10 is shown.

[0056] In some alternative embodiments, the electrical box 16 includes a box body portion 161, a cover body portion 162, and a computer board 163. The box body portion 161 defines a receiving space with an opening on the side away from the heat exchanger group 14; the cover body portion 162 is detachably arranged at the opening of the box body portion 161 to close the opening; and the computer board 163 is arranged in the receiving space.

[0057] Since the dehumidifier 10 is generally set in an environment with high air humidity, if the computer board 163 is set bare in the casing 12, the surface components of the computer board 163 are prone to aging and failure due to long-time contact with water vapor. In order to protect the computer board 163, the present embodiment specially sets the electrical box 16 with a box body 161 and a cover body 162 detachable relative to the box body 161, so that the interior of the electrical box 16 is relatively closed. The box body 161 defines a containing space away from the side of the heat exchanger group 14, so as to accommodate the computer board 163 and facilitate installation and maintenance.

[0058] In some optional embodiments, the box body 161 can be made of metal to improve the heat conduction efficiency of the electrical box 16, and to ensure the structural strength of the electrical box 16 while thinning the thickness of the box body 161. However, considering that the computer board 163 is not suitable for direct contact with the metal box body 161, the present embodiment further sets an insulating plate 164 made of non-metal material in the box body 161. The insulating plate 164 is fixed to the inner side of the box body 161; the computer board 163 is set on the insulating plate 164 to avoid direct contact with the box body 161.

[0059] Of course, in some optional embodiments, the insulating plate 164 made of non-metal material can also be set while the box body 161 made of non-metal material is set.

[0060] Reference Figure 4 As shown in the drawings, in some optional embodiments, the surface of the box body 161 is formed with at least one matching port 161A. The insulating plate 164 extends outward and downward from each matching port 161A to form a wire management groove 1641, and each wire management groove 1641 has a cable passage along the extension direction to communicate the containing space with the outside of the electrical box 16.

[0061] The computer board 163 needs to be connected to other components including fans, temperature sensors, and display control panels through cables, so the surface of the box body 161 inevitably needs to be opened for the cables to pass through, which will weaken the sealing of the electrical box 16 and cause water vapor to enter the electrical box 16 more easily. The prior art generally adopts the method of isolating the electrical box from other spaces to avoid water vapor entering, but due to the limited internal space of the dehumidifier, such a setting causes the electrical box to be generally close to the compressor, which is affected by the heat emitted by the compressor while itself is also difficult to dissipate heat effectively.

[0062] In order to reduce the moisture entering the electrical appliance box 16, the insulating plate 164 is extended outwardly and downwardly at the matching opening 161 A of the box body 161 to form a cable arranging groove 1641, each of which has a cable channel that communicates the accommodating space with the outside of the electrical appliance box 16 along the extending direction, so that the moisture is not easy to enter the electrical appliance box 16 through the cable channel. The position, number and shape of the matching opening 161 A and the cable arranging groove 1641 are set according to the preset required connection position, number and thickness of the cable, so as to reduce the gap in the cable channel after the cable is connected. Even if the moisture reaches the cable arranging groove 1641, it is easy to condense on the surface of the cable in the cable channel and the inside, and to drip outwardly and downwardly under the action of its own gravity.

[0063] Reference Figure 4 As shown in some optional embodiments, each matching opening 161 A is formed at the edge of the box body 161 close to the cover body 162; and each cable arranging groove 1641 is further formed with an opening that opens the side of the cable channel close to the cover body 162.

[0064] The matching openings 161 A of the box body 161 of the present embodiment are all formed at the edge of the box body 161 close to the cover body 162, so that the installation of the insulating plate 164 is more convenient. Meanwhile, each cable arranging groove 1641 is further formed with an opening that opens the side of the cable channel close to the cover body 162, so that the installation of the cable is more convenient, and the cable no longer has to be inserted into the cable channel, but can be clamped from the side of the cable channel.

[0065] In some optional embodiments, the insulating plate 164 defines a computer board fixing groove, and the computer board 163 is arranged in the computer board fixing groove; at least one cable arranging groove 1641 is opposite to the computer board fixing groove; the insulating plate 164 is further formed with a capacitor fixing frame 1642 for fixing the capacitor 165; and the capacitor fixing frame 1642 is spaced apart from the computer board fixing groove.

[0066] The dehumidifier 10 usually needs to be provided with a single large capacitor 165 for the fan and / or the compressor, and the present embodiment sets the capacitor 165 together with the computer board 163 in the electrical appliance box 16. In order to avoid the interference of the capacitor 165 to the computer board 163, the insulating plate 164 of the present embodiment is formed with a computer board fixing groove for fixing the computer board 163, and is further formed with a capacitor fixing frame 1642 for fixing the capacitor 165 at a position spaced apart from the computer board fixing groove in the length direction of the electrical appliance box 16.

[0067] The capacitor fixing frame 1642 is spaced apart from the computer board fixing groove. The capacitor fixing frame 1642 and the computer board fixing groove can be spaced apart in distance, i.e. there is a certain distance between the capacitor fixing frame 1642 and the computer board fixing groove, or the capacitor fixing frame 1642 and the computer board fixing groove can be spaced apart in space, i.e. a partition is formed between the capacitor fixing frame 1642 and the computer board fixing groove, for example, an insulating plate 164 is formed between the capacitor fixing frame 1642 and the computer board fixing groove to space apart the capacitor fixing frame 1642 and the computer board fixing groove.

[0068] In other optional embodiments, the insulating plate 164 can not be separately arranged in the electric appliance box 16 to form the wire arranging groove 1641, but the corresponding structure of the insulating plate 164 is integrally formed on the box body 161. That is, the box body 161 itself can extend outward and downward from the surface to form at least one wire arranging groove 1641, and each wire arranging groove 1641 has a cable passage that communicates the accommodation space with the outside of the electric appliance box 16 along the extending direction. The box body 161 of the present embodiment is made of non-metallic material.

[0069] In some optional embodiments, similar to the part of the embodiments in which the electric appliance box 16 includes the insulating plate 164, on the basis that the box body 161 itself extends outward and downward from the surface to form at least one wire arranging groove 1641, each wire arranging groove 1641 is formed at the edge of the box body 161 close to the cover body 162; and each wire arranging groove 1641 further has an opening close to the cover body 162 to make the side of the cable passage open.

[0070] At this point, those skilled in the art should recognize that, although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be determined or deduced directly according to the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variations or modifications.
