In this embodiment, the first panel 11, the second panel 13, the third panel 15, and the fourth panel 17 are all vertically arranged and connected in sequence, and the vertical side of the fourth panel 17 that is not connected to the third panel 15 is connected to the vertical side of the first panel 11 that is not connected to the second panel 13. At this time, the first panel 11, the second panel 13, the third panel 15, and the fourth panel 17 are collectively enclosed to form a prismatic tubular structure (i.e., a peripheral wall of the casing 10), and the tubular structure may be provided with components such as the cross flow fan 20, the dehumidification unit, the air make-up condenser 30, and the compressor of the dehumidifier 100. Specifically, the first panel 11 is disposed opposite to the third panel 15, and the second panel 13 is disposed opposite to the fourth panel 17. And, the second air inlet 151 is disposed adjacent to the second panel 13, and the third air inlet 153 is disposed adjacent to the fourth panel 17.

The impeller 23 extends in the height direction of the casing 10, and at this time, the height of each air inlet in the height direction of the casing 10 corresponds to the height of the impeller 23, and the height of the air outlet 171 in the height direction of the casing 10 corresponds to the height of the impeller 23.

Of the three heat exchangers, two are dehumidification assemblies (first dehumidification assembly 30 and second dehumidification assembly 40), and one is a make-up condenser 50. In this embodiment, the first dehumidifying component 30 is a first heat exchanger 30a, which is disposed corresponding to the first air inlet 111. The second dehumidifying component 40 is a second heat exchanger 40a, which is disposed corresponding to the second air inlet 151. The air-supplementing condenser 50 is a third heat exchanger 50a, which is disposed corresponding to the third air inlet 153. Specifically, the first dehumidifying assembly 30 includes a first dehumidifying evaporator 31 and a first dehumidifying condenser 33, the first dehumidifying evaporator 31 and the first dehumidifying condenser 33 are respectively connected in the refrigerant circulation line, and the first dehumidifying evaporator 31 and the first dehumidifying condenser 33 are sequentially stacked along the air inlet direction of the first air inlet 111. The second dehumidifying assembly 40 includes a second dehumidifying evaporator 41 and a second dehumidifying condenser 43, wherein the second dehumidifying evaporator 41 and the second dehumidifying condenser 43 are also respectively connected in the refrigerant circulation pipeline, and the second dehumidifying evaporator 41 and the second dehumidifying condenser 43 are sequentially stacked along the air inlet direction of the second air inlet 151.

Thus, when the cross-flow fan 20 works, the air flow introduced from the first air inlet 111 can be condensed and dehumidified by the first dehumidification evaporator 31, and then heated by the first dehumidification condenser 33 to raise the temperature, so as to complete the dehumidification process; the air flow introduced from the second air inlet 151 may be condensed and dehumidified by the second dehumidifying evaporator 41, and then heated by the second dehumidifying condenser 43 to complete the dehumidifying process; the air flow introduced from the third air inlet 153 may pass through the supplementary air condenser 50 to complete the heating and warming process. Then, the three airflows are converged in the air duct 10a in the casing 10 and flow along the air duct 10a, pass through the cross-flow fan 20, and finally are discharged from the air outlet 171.

In the technical scheme of the invention, a first panel 11, a second panel 13, a third panel 15 and a fourth panel 17 which are sequentially connected are arranged on a shell 10 of a dehumidifier 100, a first air inlet 111 is formed in the first panel 11, a second air inlet 151 and a third air inlet 153 are formed in the third panel 15, an air outlet 171 is formed in the fourth panel 17, a heat exchanger is respectively arranged corresponding to the first air inlet 111, the second air inlet 151 and the third air inlet 153, the three heat exchangers are a combination of a two-dehumidification component and a one-air-supply condenser 50, and meanwhile, a cross-flow fan 20 is arranged in an air duct 10a in the shell 10 of the dehumidifier 100. In this way, two air flows of the three air flows introduced from the first air inlet 111, the second air inlet 151 and the third air inlet 153 pass through the dehumidifying component to dehumidify, and then become dry cold air; the other air flow passing through the air-supplementing condenser 50 is heated to be warmed up and changed into warm air. After the three airflows are converged, the air outlet temperature of the airflows sent out through the air outlet 171 of the dehumidifier 100 can be more approximate to the room temperature, and the use comfort of a user is ensured.

Compared with single air inlet, the design of the three air inlet can effectively increase the air inlet area, improve the air quantity of the fan at the same rotating speed, reduce the power consumption under the same air quantity, reduce the power of the whole machine, and further improve the energy efficiency level of the dehumidifier 100. Meanwhile, after the air inlet area is increased, the air inlet speed under the same air quantity can be reduced, the time of the air passing through the dehumidification assembly and the air supplementing condenser 50 is prolonged, the dehumidification time of the air flow and the heating time of the air flow are improved, the dehumidification quantity, the dehumidification energy efficiency and the heat exchange efficiency of the heat exchanger are improved, and the energy efficiency level of the dehumidifier 100 is further improved. In addition, the air quantity is increased, and the surging of the air outlet 171 can be effectively avoided or weakened.

Specifically, the air-supplementing condenser 50 may be respectively communicated with the first dehumidifying condenser 33 in the first dehumidifying assembly 30 and the second dehumidifying condenser 43 in the second dehumidifying assembly 40, and also communicated with the refrigerant circulation line. At this time, the refrigerant is compressed by the compressor to form a high-temperature and high-pressure gaseous refrigerant, and flows to the air-supplementing condenser 50, the high-temperature and high-pressure gaseous refrigerant is primarily radiated and cooled in the air-supplementing condenser 50, then flows to the first dehumidifying condenser 33 and the second dehumidifying condenser 43 respectively, and is secondarily radiated and cooled in the first dehumidifying condenser 33 and the second dehumidifying condenser 43, then is respectively passed through the throttling device to form a low-temperature and low-pressure liquid refrigerant, and flows to the first dehumidifying evaporator 31 and the second dehumidifying evaporator 41, the low-temperature and low-pressure liquid refrigerant absorbs the heat in the air in the first dehumidifying evaporator 31 and the second dehumidifying evaporator 41 to evaporate, and simultaneously, the air is cooled and condensed, the refrigerant is also converted from a liquid state to a gaseous state, and finally the refrigerant returns to the compressor to complete a refrigerant circulation process. Obviously, when the refrigerant passes through the above process, two gradients and step-by-step heat exchange are realized on the air supplementing condenser 50 and the first dehumidifying condenser 33 (the second dehumidifying condenser 43), and the heat exchange process is more efficient and more sufficient, and is more beneficial to obtaining the refrigerant with low temperature, so that the heat exchange efficiency of the refrigerant in the first dehumidifying evaporator 31 (the second dehumidifying evaporator 41) is further effectively improved, the overall power and the overall energy consumption are reduced, and the energy efficiency level of the dehumidifier 100 is further improved.

In addition, in other embodiments, the refrigerant circulation flow path can be reasonably adjusted according to actual requirements, so that comprehensive performance optimization in various aspects such as structure, energy efficiency and the like can be realized under other conditions. In addition, the positions of the first dehumidifying component 30, the second dehumidifying component 40 and the air compensating condenser 50 can be reasonably adjusted according to actual requirements, for example, the first heat exchanger 30a is the air compensating condenser 50 or the second heat exchanger 40a is the air compensating condenser 50, so that the structural arrangement is more flexible and the practicability is higher.

In addition, the first heat exchanger 30a is fixed by the first partition plate 113 and the second partition plate 131, so that the setting stability of the first heat exchanger 30a can be effectively improved, and the working capacity of the first heat exchanger is ensured.

In addition, the first heat exchanger 30a is disposed at an included angle with the first panel 11, so that the space inside the housing 10 can be effectively and reasonably utilized, and the plurality of condensers and evaporators can be closely arranged, thereby maximally utilizing the space, reducing the size of the dehumidifier 100 and reducing the space occupation ratio of the dehumidifier 100.

And, the third partition plate 133 and the fourth partition plate 155 are utilized to fix the second heat exchanger 40a, so that the setting stability of the second heat exchanger 40a can be effectively improved, and the working capacity of the second heat exchanger is ensured.

Further, the angle between the second heat exchanger 40a and the third panel 15 is defined as α2, and α2 is 0 degree or more and 80 degrees or less.

In addition, the second heat exchanger 40a is disposed at an included angle with the third panel 15, so that the space inside the housing 10 can be effectively and reasonably utilized, and the plurality of condensers and evaporators can be closely arranged, thereby maximally utilizing the space, reducing the size of the dehumidifier 100 and reducing the space occupation ratio of the dehumidifier 100.

In addition, in other embodiments of the dehumidifier 100 of the present invention, the portion of the second panel 13 adjacent to the first air inlet 111 and/or the portion of the second panel 13 adjacent to the second air inlet 151 may be provided with an air supply port, and the air supply port may be communicated with the corresponding air inlet or may be disposed at intervals, so as to further increase the air intake of the dehumidifier 100, improve the heat exchange efficiency of the whole machine, and improve the energy level of the whole machine.

As shown in fig. 1 and 2, the first heat exchanger 30a, the second heat exchanger 40a, and the third heat exchanger 50a may also be sequentially abutted against and disposed around the cross flow fan 20. In this embodiment, two ends of the second dehumidifying component 40 are respectively abutted against the air compensating condenser 50 and the first dehumidifying component 30. Thus, through a reasonable structural design, a compact arrangement of a plurality of condensers and evaporators is realized, space is utilized to the maximum extent, and the body size of the dehumidifier 100 is reduced.
