[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] The following is for reference. Figure 1 and Figure 2 This invention describes the air outlet structure and heat pump dehumidifier according to embodiments of the present invention.

[0026] The air vent structure of the first aspect of this utility model includes an air vent body 201 and a rain cover 200 covering the outside of the air vent body 201. The axial direction of the air vent body 201 is transverse. The rain cover 200 includes a transversely extending cylindrical shell and two baffles disposed inside the cylindrical shell. The left and right ends of the cylindrical shell are open. The two baffles are vertically arranged and spaced apart in the transverse direction. The two baffles are staggered front to back. A drain outlet 230 is provided at the bottom of the cylindrical shell.

[0027] The air vent body 201 is located on the outer casing 100 of the heat pump dehumidifier. The air vent body 201 can be used to draw in fresh air. The outer side of the outer casing 100 of the heat pump dehumidifier is the outer side of the air vent body 201. The air vent body 201 is rectangular, and the cylindrical shell is rectangular. Taking the air vent body 201 located on the left side of the outer casing 100 of the heat pump dehumidifier as an example, the cylindrical shell is located on the left side of the air vent body 201, and the right end of the cylindrical shell is sleeved outside the air vent body 201 and sealed to the left side of the outer casing 100.

[0028] The two baffles are referred to as the first plate 210 and the second plate 220, respectively. The first plate 210 is located to the left of the second plate 220. The top edge of the first plate 210 is connected to the top wall of the cylindrical shell, the front edge of the first plate 210 is connected to the front wall of the cylindrical shell, the bottom edge of the first plate 210 is connected to the bottom wall of the cylindrical shell, and a first air duct is formed between the rear edge of the first plate 210 and the rear wall of the cylindrical shell. The top edge of the second plate 220 is connected to the top wall of the cylindrical shell. The rear edge of plate 0 is connected to the rear wall of the cylindrical shell, the bottom edge of plate 220 is connected to the bottom wall of the cylindrical shell, and a second air duct is formed between the front edge of plate 220 and the front wall of the cylindrical shell; the sum of the front and rear dimensions of plate 210 and plate 220 is greater than the front and rear dimensions of the cylindrical shell, so that the first air duct and the second air duct are misaligned to block rainwater; the drain outlet 230 is a drainage through hole provided on the bottom wall of the cylindrical shell, and the number of drainage through holes can be multiple.

[0029] When in use, the air vent structure can be set in the heat pump dehumidifier as the fresh air inlet of the heat pump dehumidifier. When fresh air needs to be drawn in, the airflow needs to pass through the cylindrical shell laterally to reach the air vent body 201. Due to the two baffles that are staggered front and back, the airflow cannot pass through the cylindrical shell in a straight line, but needs to turn. This causes raindrops to hit the baffles and the side wall of the cylindrical shell under the action of inertia, or fall to the inner wall of the cylindrical shell under the influence of gravity, and then be discharged from the drain outlet 230. This achieves the purpose of separating rainwater from airflow and reduces the short circuit risk of the heat pump dehumidifier.

[0030] In some embodiments of this utility model, the vertical dimension of the air vent body 201 is larger than its front-to-back dimension. This results in a smaller front-to-back dimension of the baffle, lower wind resistance of the rain cover 200, and a larger flow area of ​​the air vent body 201.

[0031] In some embodiments of this utility model, an air vent body 201 is connected to an air valve 240, which is located between the air vent body 201 and two baffles. By providing the air valve 240, it is convenient to control the opening or closing of the air vent body 201. The rain cover 200 also protects the air valve 240, allowing it to be located on the outside of the heat pump dehumidifier to save internal space. The air valve 240 can be an electrically controlled valve; it is a conventional component in this field, and its specific structure will not be described in detail here.

[0032] The heat pump dehumidifier of the second aspect of this utility model includes a housing 100 and a heat pump dehumidification system. The housing 100 is provided with at least one of the above-mentioned air vent structures. An airflow channel is provided inside the housing 100, and the air vent body 201 is connected to the airflow channel. The airflow channel has an air inlet section 101, an air outlet section 103, and a dehumidification section 102 connected between the air inlet section 101 and the air outlet section 103. The air inlet section 101 is provided with a dehumidification inlet 110, and the air outlet section 103 is provided with a dehumidification outlet 120. The heat pump dehumidification system is located inside the dehumidification section 102.

[0033] For example, such as Figure 1 As shown, the heat pump dehumidifier's outer casing 100 is rectangular, with a horizontally arranged airflow channel. The air inlet section 101 is located at the left end inside the casing 100, the exhaust section 103 is located at the right end inside the casing 100, and the dehumidification section 102 is located between the air inlet section 101 and the exhaust section 103. The dehumidification inlet 110 is located on the left side wall of the casing 100, and the dehumidification outlet 120 is located on the right side wall of the casing 100. The airflow direction in the airflow channel is from left to right. The dehumidification inlet 110 is connected to the indoor environment to draw indoor air into the dehumidification section 102 for dehumidification, and the dehumidification outlet 120 is connected to the indoor environment to return the dehumidified air to the room.

[0034] The heat pump dehumidification system includes a compressor 610, a condenser 620, a throttling device 630, and an evaporator 640. The compressor 610 has a refrigerant outlet and a refrigerant inlet. The condenser 620, the throttling device 630, and the evaporator 640 are connected sequentially between the refrigerant outlet and the refrigerant inlet. Both the evaporator 640 and the condenser 620 are vertically arranged, with the evaporator 640 located to the left of the condenser 620. This allows air entering from the dehumidification inlet 110 to first pass through the evaporator 640 for cooling and dehumidification, then pass through the condenser 620 for heating and temperature restoration, and finally be discharged from the dehumidification outlet 120. In addition, the heat pump dehumidification system may also include components such as a liquid receiver, a gas-liquid separator, and an oil separator. The heat pump dehumidification system is a conventional technology in this field, and its specific structure will not be described in detail here.

[0035] The air vent structure can be set in the air inlet section 101, dehumidification section 102, or exhaust section 103, as long as it can replenish fresh air. By setting the above-mentioned air vent structure, when fresh air needs to be drawn in, the airflow needs to pass through the cylindrical shell axially to enter the airflow channel. Since there are two baffles, the airflow cannot pass through the cylindrical shell in a straight line, but needs to turn. This causes raindrops to hit the baffles and the side wall of the cylindrical shell under the action of inertia, or fall to the inner wall of the cylindrical shell under the influence of gravity, thereby achieving the purpose of separating rainwater from airflow and reducing the short-circuit risk of the heat pump dehumidifier.

[0036] In some embodiments of this utility model, the exhaust section 103 is provided with a flow-promoting fan 130. The flow-promoting fan 130 promotes the circulation of air between the indoor unit and the heat pump dehumidifier.

[0037] In some embodiments of this invention, a sterilization component 400 is provided between the air inlet section 101 and the dehumidification section 102. Thus, in addition to dehumidification, the heat pump dehumidifier can also sterilize the air drawn from the room before returning it to the room.

[0038] In some embodiments of this invention, the sterilization component 400 is an ultraviolet germicidal lamp. This results in a simple structure and easy installation.

[0039] In some embodiments of this utility model, a filter element 300 is provided between the air inlet section 101 and the dehumidification section 102. The filter element 300 can be a filter screen; thus, in addition to dehumidification, the heat pump dehumidifier can also filter the air drawn from the room before returning it to the room.

[0040] In some embodiments of this utility model, the outer casing 100 is provided with two air vent structures, one of which is equipped with an exhaust fan 510. One air vent structure serves as a fresh air inlet, and the other serves as an exhaust outlet 500, with the exhaust fan 510 located at the exhaust outlet 500. When the exhaust fan 510 is activated, a portion of the air in the airflow channel is discharged outward from the exhaust outlet 500. To replenish this discharged air, the fresh air inlet can naturally draw in fresh air, making it easy to control the amount of fresh air drawn in. The exhaust fan 510 can be located inside the outer casing 100 and can be a centrifugal fan.

[0041] In some embodiments of this utility model, the dehumidification inlet 110 is located at the left end of the outer casing 100, and the air inlet section 101, dehumidification section 102, and exhaust section 103 are arranged sequentially from left to right. Two air vent structures are respectively located on the front and rear sides of the dehumidification inlet 110. In this way, the air drawn in from the fresh air inlet can also be filtered by the filter component 300 and sterilized by the sterilization component 400, and then dehumidified by the dehumidification section 102 before being sent to the room. In addition, by setting the exhaust vent 500 and the fresh air inlet on the front and rear sides of the dehumidification inlet respectively, the indoor air drawn in from the dehumidification inlet 110 can be separated from the exhaust vent 500 and the fresh air inlet. This allows the fresh air drawn in from the fresh air inlet to be delivered to the right to the dehumidification channel, and the air discharged from the exhaust vent 500 is the indoor air drawn in from the dehumidification inlet 110, preventing the fresh air drawn in from the fresh air inlet from being discharged from the exhaust vent 500, thus improving the effect of supplying fresh air to the room.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
