[0029] The box-type dehumidifier unit according to the embodiment of the present invention comprises a box body 100, a sterilizing device and a heat pump dehumidification device.

[0030] like Figure 1 As shown, the box body 100 is in the shape of a rectangular parallelepiped, and an air inlet chamber 110, a dehumidification chamber 120 and an exhaust chamber 130 are arranged inside the box body 100. The air inlet chamber 110, the dehumidification chamber 120 and the exhaust chamber 130 are arranged in sequence from left to right, and the air inlet chamber 110, the dehumidification chamber 120 and the exhaust chamber 130 are connected in sequence; the air inlet chamber 110 is provided with a fresh air inlet and a return air inlet 112, the fresh air inlet can be arranged on the left side of the air inlet chamber 110, and the return air inlet 112 can be arranged on the top of the air inlet chamber 110, the fresh air inlet is used to connect to the outdoor environment, the fresh air inlet can be provided with a fresh air duct, and the two ends of the fresh air duct are respectively connected to the fresh air inlet and the outdoor environment; the return air inlet 112 is used to connect For the indoor environment that needs dehumidification, the return air outlet 112 can be provided with a return air duct, and the two ends of the return air duct are respectively connected to the return air outlet 112 and the indoor environment that needs dehumidification; the fresh air outlet is provided with a fresh air valve 111, and the fresh air valve 111 can be a shutter valve to control whether fresh air is allowed to enter; the exhaust chamber 130 is provided with an exhaust outlet 133, and the exhaust outlet 133 is used to be connected to the indoor environment that needs dehumidification. The exhaust outlet 133 can be provided with an exhaust duct, and the two ends of the exhaust duct are respectively connected to the exhaust outlet 133 and the indoor environment that needs dehumidification; the exhaust chamber 130 is provided with a flow-promoting fan 132, and the flow-promoting fan 132 is used to supply air from the dehumidification chamber 120 to the exhaust outlet 133.

[0031] The sterilization device is disposed between the air inlet chamber 110 and the dehumidification chamber 120;

[0032] The heat pump dehumidification device is arranged in the dehumidification chamber 120, wherein the dehumidification chamber 120 can also be provided with a wire trough for routing power lines, signal lines and other wires. The wire trough is arranged horizontally and at the top of the dehumidification chamber 120 to prevent leakage or failure caused by flooding to a certain extent.

[0033] During use, the air in the indoor environment that needs to be dehumidified enters the box body 100 from the return air outlet 112, passes through the air inlet chamber 110, the dehumidification chamber 120 and the exhaust chamber 130 in sequence, and is then transported back to the indoor environment that needs to be dehumidified from the exhaust air outlet 133.

[0035] In some embodiments of the present invention, the box-type dehumidifier unit further includes a filter device 200, which is disposed at one end of the air inlet chamber 110 close to the dehumidification chamber 120. The filter device 200 can filter dust and other debris in the air, so that the air sucked into the air inlet chamber 110 can be filtered before reaching the location of the germicidal lamp, which is conducive to keeping the surface of the germicidal lamp clean and preventing dust from covering the germicidal lamp.

[0036] In some embodiments of the present invention, reference Figure 2 The filter device 200 includes a mounting frame 210 and a plurality of filter components 220. The mounting frame 210 is provided with a plurality of mounting locations 230. The plurality of filter components 220 are arranged in a one-to-one correspondence at the plurality of mounting locations 230. The filter components 220 are detachably connected to the mounting frame 210. The plurality of mounting locations 230 are arranged in a rectangular array in the flow cross section of the air inlet chamber 110. The mounting locations 230 are provided with a second through hole that transversely penetrates the mounting frame 210. The filter components 220 are arranged in the second through hole. The filter components 220 may be a filter net. The filter components 220 and the mounting frame 210 may be detachably connected by bolt connection, clamping or other suitable means; this facilitates the replacement of a filter component 220 individually.

[0037] In some embodiments of the present invention, a germicidal lamp is disposed at the mounting portion 230, and the germicidal lamp is detachably connected to the mounting frame 210. A germicidal lamp is disposed in each second through hole, and multiple germicidal lamps are evenly disposed in multiple second through holes. When the germicidal lamp needs to be replaced, the filter component 220 disposed at the same mounting portion 230 is first removed, and then the lamp can be disassembled and assembled from the air inlet chamber 110. Both the germicidal lamp and the filter component 220 can be disassembled and assembled from the air inlet chamber 110, and there is no need to remove the evaporator 350 located on the right side of the mounting frame 210. The operation is relatively simple, and there is no need to leave space between the mounting frame 210 and the evaporator 350 to disassemble and assemble the germicidal lamp. The structure of the box-type dehumidifier unit is more compact. Among them, the germicidal lamp and the mounting frame 210 can be detachably connected by bolt connection, clamping or other suitable methods.

In this embodiment, the connecting pipeline is supported by the support column, which is conducive to making the structure of the connecting pipeline more stable.

[0040] In some embodiments of the present invention, the support column includes an upper column section 420 and a lower column section 410, the top end of the upper column section 420 is connected to the top wall of the box 100, and the bottom end of the lower column section 410 is connected to the bottom wall of the box 100. In this way, the support column can also play a role in strengthening the structure of the box 100.

[0041] In some embodiments of the present invention, the upper column section 420 and the lower column section 410 are connected by sliding up and down, and a locking mechanism is provided between the upper column section 420 and the lower column section 410. In this way, the support column can be extended and retracted. When manufacturing a box-type dehumidifier unit, the box body 100 and the heat pump dehumidifier can be assembled first, and then the support column can be shortened, and the support column can be set according to the actual route of the connecting pipeline, and then the support column can be extended and fixedly connected to the box body 100. The support column can be flexibly set, which is convenient for the production and manufacturing of the box-type dehumidifier unit. The upper column section 420 and the lower column section 410 are connected with a sliding sleeve 430, the upper sliding sleeve of the sliding sleeve 430 is arranged on the bottom of the upper column section 420, and the lower sliding sleeve of the sliding sleeve 430 is arranged on the top of the lower column section 410 to realize the sliding connection between the upper column section 420 and the lower column section 410; the locking mechanism includes two locking members 431, one of which is connected between the sliding sleeve 430 and the lower column section 410, and the other is connected between the sliding sleeve 430 and the upper column section 420, and the locking member 431 can be a bolt.

[0042] Among them, the height position of the sliding sleeve 430 is located at the upper part of the support column, and the support seat 440 is arranged on the lower column section 410, so that the vertical position of the support seat 440 will not change when the position of the upper column section 420 is adjusted, so that during assembly, the heat pump dehumidification device can be installed in the box body 100 first, and then the support column is placed in the box body 100, and then the support seat 440 is used to connect the lower column section 410 with the connecting pipe, and then the position of the upper column section 420 is adjusted and connected to the box body 100, and the operation is relatively simple.

[0043] In other embodiments of the present invention, referring to Figure 3 The evaporator 350 is provided with a plurality of evaporation pipelines 351, and the condenser 320 is provided with a plurality of condensation pipelines 321; the heat pump dehumidification device includes a plurality of heat pump units, each of which includes a connecting pipeline, a compressor 310, a condensation pipeline 321, a throttling component and an evaporation pipeline 351, and the compressor 310, the condensation pipeline 321, the throttling component and the evaporation pipeline 351 are connected end to end through the connecting pipeline. In this way, each heat pump unit can operate independently, and if one of the heat pump units fails, the remaining heat pump units can also support the operation of the box-type dehumidification unit.

[0044] The evaporator 350 includes a plurality of heat exchange fins, each evaporation pipeline 351 includes a plurality of tube groups 352, each tube group 352 includes a plurality of tube sections, each tube section runs through all the heat exchange fins and contacts the heat exchange fins, so that heat conduction can be performed between the tube sections and the heat exchange fins; the space where the plurality of heat exchange fins are located is called a heat exchange space, and the heat exchange space has a plurality of first areas in vertical partitioning, and the plurality of first areas are arranged in sequence along the vertical direction. For any first area, each evaporation pipeline 351 has a tube group 352 arranged therein; the heat exchange space has a plurality of second areas in horizontal partitioning (i.e., the thickness direction of the evaporator). Area, multiple second areas are arranged in sequence along the horizontal direction, for any second area, each evaporation pipeline 351 has a tube group 352 arranged therein; in this way, each evaporation pipeline 351 has some tube groups 352 that are closer to the air inlet chamber 110, and some tube groups 352 that are farther away from the air inlet chamber 110, so that the heat absorption efficiency of each evaporation pipeline 351 is relatively consistent, which is beneficial to the stable operation of the heat pump dehumidification device, especially when some of the heat pump units fail, the remaining heat pump units can still make full use of the flow area of ​​the evaporator 350 for heat exchange; the structure of the condenser 320 is consistent with the structure of the evaporator 350.
