[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] Please refer to Figure 1 and Figure 2 A low-temperature mixing air cabinet matched with a low-temperature dehumidifier 1, the low-temperature dehumidifier 1 includes a return air duct 11, the return air duct 11 is connected to the room, and the low-temperature mixing air cabinet is arranged between the return air duct 11 and the room; the low-temperature mixing air cabinet includes a low-temperature air bin 2, a return air bin 3, a mixing air bin 4 and a return air fan 5, the low-temperature air bin 2 is connected to the return air duct 11, the return air bin 3 is connected to the room, and a return air fan 5 is arranged between the return air bin 3 and the room; the low-temperature air bin 2 and the return air bin 3 are both connected to the mixing air bin 4, and the mixing air bin 4 is connected to the room.

[0019] From the above description, it can be seen that the beneficial effects of the present invention are: through the design of a low-temperature mixing air cabinet between the return air duct 11 and the indoor room, the low-temperature supply air after dehumidification by the low-temperature dehumidifier 1 can be mixed with the indoor return air delivered by the return air fan 5 to form a supply air with suitable temperature input into the indoor room, thereby avoiding the supply air temperature being too low and avoiding the phenomenon of condensation on the supply air; through the rapid return air to the room by the return air fan 5, compared with the dehumidification and purification treatment that requires a longer process for a single dehumidifier, it can be mixed with the low-temperature supply air of the dehumidifier to make the room quickly reach the appropriate temperature and humidity, reduce the number of ventilation times in the room, and save the energy consumption of the dehumidifier; at the same time, the low-temperature mixing air cabinet can be used as a part of the return air duct 11, thereby reducing the large number of return air ducts originally required to connect the dehumidifier to the indoor room, thereby reducing equipment costs.

[0020] Furthermore, a check valve baffle 7 is provided at the connection point between the low-temperature air bin 2 and the air mixing bin 4 and at the connection point between the return air bin 3 and the air mixing bin 4 .

[0021] It can be seen from the above description that the design of the check valve baffle 7 can prevent the mixed air from flowing back in the mixed air chamber 4, thereby achieving directional control of the air supply.

[0022] Furthermore, the low-temperature air mixing cabinet also includes an air supply bin 8, and the air supply bin 8 is arranged between the air mixing bin 4 and the room.

[0023] From the above description, it can be seen that the air supply chamber 8 is used to directly connect with the indoor room. After the low-temperature supply air of the low-temperature air chamber 2 and the indoor return air of the return air chamber 3 are fully mixed in the mixing air chamber 4, they are sent into the room through the air supply chamber 8.

[0024] Furthermore, a flow equalizing plate 9 is provided in the air supply bin 8 .

[0025] It can be seen from the above description that the arrangement of the flow equalizing plate 9 enables the mixed air in the air mixing chamber 4 to be evenly distributed when output.

[0026] Furthermore, a filter 10 is provided in the air supply bin 8 ; and a flow equalizing plate 9 and a filter 10 are sequentially provided along the air supply direction of the air supply bin 8 .

[0027] It can be seen from the above description that the mixed air in the air mixing chamber 4 is evenly distributed through the flow equalizing plate 9 in the air supply chamber 8, and then filtered and purified by the filter 10, and finally delivered into the room.

[0028] Furthermore, the low-temperature mixing air cabinet also includes an exhaust fan 6 , and the exhaust fan 6 is arranged between the return air duct 11 and the low-temperature air bin 2 .

[0029] From the above description, it can be seen that the design of the exhaust fan 6 in the return air duct 11 and the low-temperature air bin 2 can ensure the input of the processed low-temperature supply air of the dehumidifier, and at the same time can replace the fan in the dehumidifier to ensure the air volume, thereby reducing the components of the dehumidifier and reducing the equipment cost of the dehumidifier.

[0030] Further, the return fan 5 is an EC return fan 5 ; and the exhaust fan 6 is an EC exhaust fan 6 .

[0031] From the above description, it can be seen that the arrangement of the variable frequency EC return fan 5 and the EC exhaust fan 6 can intelligently control the supply air volume, mixed air volume, etc. to ensure that the low-temperature mixing air cabinet can output supply air with appropriate temperature and humidity.

[0032] Furthermore, the connection point between the return air duct 11 and the low-temperature air bin 2 is opposite to the inner wall of the low-temperature air bin 2; the connection point between the indoor room and the return air bin 3 is opposite to the inner wall of the return air bin 3.

[0033] From the above description, it can be seen that through the connection between the return air duct 11 and the low-temperature air bin 2 and the connection between the indoor and the return air bin 3, the low-temperature air bin 2 and the return air bin 3 are respectively set relative to the low-temperature air bin 2 and the return air bin 3, so that the low-temperature air bin 2 and the return air bin 3 can play the role of buffer storage.

[0035] Application scenario: When using a dehumidifier, when the cleanliness of the room needs to be improved, the ventilation frequency of the room and the air supply of the dehumidifier need to be increased, but this will increase the cost of the equipment and increase the energy consumption of operation; at the same time, the direct air supply of the low-temperature dehumidifier 1 may have an air supply temperature that is too low, causing discomfort to the human body and causing condensation on the air supply.

[0036] like Figure 1 and Figure 2 As shown, the low-temperature mixing air cabinet of this embodiment is matched with the low-temperature dehumidifier 1, and the matched low-temperature dehumidifier 1 includes a fresh air duct, a dehumidification wheel, a cooling component, a filter component, a return air duct 11, a regeneration air duct and a heating component. After the air enters the fresh air duct, it is dehumidified, cooled and purified through the dehumidification wheel, the cooling component and the filter component, and then sent into the room along the return air duct 11, and then the return air in the room is sent back to the fresh air duct through another section of the return air duct 11; a part of the supply air in the fresh air duct will be sent to the regeneration air duct, and the heat and moisture content will be exchanged with the dehumidification wheel through the heating component to make the dehumidification wheel recycled and finally discharged outdoors.

[0037] The low-temperature mixing air cabinet is arranged between the return air duct 11 and the room, replacing part of the return air duct 11, and reducing the use of the return air duct. The low-temperature mixing air cabinet comprises a cabinet body, a low-temperature air bin 2, an exhaust fan 6, a return air bin 3, a mixing air bin 4, a return air fan 5, an air supply bin 8, a check valve baffle 7 and a flow equalizer. The cabinet body is provided with parallel low-temperature air bins 2 and return air bins 3, mixing air bins 4 and air supply bins 8 in sequence along the air outlet direction.

[0039] The low-temperature air bin 2 and the return air bin 3 are both connected to the mixed air bin 4. The connection between the low-temperature air bin 2 and the mixed air bin 4 and the connection between the return air bin 3 and the mixed air bin 4 are both provided with a check valve baffle 7. The check valve baffle 7 is provided to prevent the mixed air in the mixed air bin 4 from flowing back.

[0040] The air mixing chamber 4 is connected to the air supply chamber 8, and the air supply chamber 8 is connected to the room; the air supply chamber 8 is provided with a flow equalizer 9 and a filter 10 in sequence along the air supply direction of the air supply chamber 8, so that the mixed air can be evenly diverted, filtered and purified in sequence. The flow equalizer 9 is a porous grille plate formed by uniformly opening holes in a steel plate.

[0041] Working principle: After the low-temperature dehumidifier 1 cools, dehumidifies and filters the outdoor fresh air, it is sent to the low-temperature air bin 2 through the exhaust fan 6 of the low-temperature mixing air cabinet, and at the same time, a part of the indoor return air is sent to the return air bin 3 through the return fan 5 of the low-temperature mixing air cabinet; the exhaust fan 6 and the return fan 5 are both variable-frequency EC fans, which can intelligently control the air supply volume, etc.; thereafter, the low-temperature supply air in the low-temperature air bin 2 and the indoor return air in the return air bin 3 are mixed in the mixing air bin 4 to form supply air with appropriate temperature and humidity; thereafter, the air is evenly distributed in the supply air bin 8 through the equalizing plate 9, filtered and purified by the filter 10, and then sent into the room.

[0042] To sum up, the low-temperature mixing air cabinet matched with the low-temperature dehumidifier provided by the utility model can make the low-temperature supply air after dehumidification by the low-temperature dehumidifier and the indoor return air transported by the return air fan mixed to form the supply air with suitable temperature to be input into the indoor, so as to avoid the supply air temperature being too low and the phenomenon of condensation on the supply air; through the rapid return air to the indoor by the return air fan, compared with the dehumidification and purification treatment of a single dehumidifier which requires a longer process, it can be mixed with the low-temperature supply air of the dehumidifier to make the room quickly reach the appropriate temperature and humidity, reduce the ventilation times of the room, reduce the air supply volume of the dehumidifier, and save the energy consumption of the dehumidifier; at the same time, the low-temperature mixing air cabinet can be used as a part of the return air duct, thereby reducing the large number of return air ducts originally required to connect the dehumidifier with the indoor room, thereby reducing the equipment cost.
