Finally, the air is blown out through the air outlet 171 via the cross flow fan 20.

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 on the first panel 11, a second air inlet 151 is formed on the third panel 15, an air outlet 171 is formed on the fourth panel 17, a sensible heat exchanger 30 is arranged in the shell 10 of the dehumidifier 100, a first air inlet 311 is communicated with the first air inlet 111, a second air inlet 331 is communicated with the second air inlet 151, meanwhile, a cross flow fan 20 is arranged in the shell 10 of the dehumidifier 100, an air inlet side is communicated with a first air outlet 313 and a second air outlet 333 of the sensible heat exchanger 30, an air outlet side is communicated with the air outlet 171, a first evaporator 40 and a first condenser 60 are arranged at corresponding positions in a first air path 10a in the shell 10, and a second evaporator 50 and a second condenser 70 are arranged at corresponding positions in a second air path 10b in the shell 10.

In addition, according to the technical scheme of the invention, only one sensible heat exchanger 30 is arranged in the dehumidifier 100, and is tightly matched with related structures, so that the internal structure of the dehumidifier 100 is compact, the transverse width of the dehumidifier 100 is reduced, the whole dehumidifier is smaller in size, the manufacturing cost is reduced, and the dehumidifier is more convenient for users to accept. Meanwhile, the dehumidifier 100 has small wind resistance and large wind quantity, and can effectively avoid or weaken the surge phenomenon of the air outlet 171.

In this embodiment, the end of the partition plate 131 away from the second panel 13 abuts against the junction of the first air inlet 311 and the second air inlet 331 of the sensible heat exchanger 30, and a flow channel can be formed between the junction of the partition plate 131 and the first air inlet 311 and the second air outlet 333 of the sensible heat exchanger 30, wherein one end of the flow channel is communicated with the first air inlet 111, and the other end is communicated with the first air inlet 311. The flow channel can guide the air flow introduced from the first air inlet 111, so that the air flow can smoothly pass through the first evaporator 40 and enter the first air channel 31 of the sensible heat exchanger 30 through the first air inlet 311. On the one hand, the wind resistance is effectively reduced, and the air quantity is improved, so that the cooling and dehumidifying efficiency of the first evaporator 40 and the heating and warming efficiency of the first condenser 60 are effectively improved, namely, the heat exchange efficiency of a heat exchanger in the dehumidifier 100 is effectively improved, the energy consumption of the whole dehumidifier is reduced, and the dehumidifying efficiency and the energy efficiency level of the dehumidifier 100 are improved; on the other hand, the effective recovery of the residual cooling by the sensible heat exchanger 30 is also ensured.

In this embodiment, the end of the baffle 155 far from the third panel 15 is connected to the junction between the second air inlet 331 and the first air outlet 313 of the sensible heat exchanger 30 through a connecting plate, and a flow channel is formed between the baffle 155 and the partition 131, and one end of the flow channel is communicated with the second air inlet 151, and the other end is communicated with the second air inlet 331. The flow channel can guide the air flow introduced from the second air inlet 151 so that the air flow can smoothly enter the second air channel 33 of the sensible heat exchanger 30 through the second air inlet 331. Thus, on one hand, the wind resistance is effectively reduced, and the air quantity is improved, so that the cooling and dehumidifying efficiency of the second evaporator 50 and the heating and warming efficiency of the second condenser 70 are effectively improved, namely, the heat exchange efficiency of a heat exchanger in the dehumidifier 100 is effectively improved, the energy consumption of the whole dehumidifier is reduced, and the dehumidifying efficiency and the energy efficiency level of the dehumidifier 100 are improved; on the other hand, the effective utilization of the recovered residual cold by the sensible heat exchanger 30 is also ensured, so that the power consumption of the whole machine is further reduced, and the energy efficiency level of the whole machine is improved.

As shown in fig. 1 and 2, the inner wall surface of the first panel 11 is provided with a baffle 115 adjacent to the fourth panel 17, the baffle 115 extends toward the end of the inner volute of the cross-flow fan 20 adjacent to the air inlet side thereof and is connected with the end of the inner volute adjacent to the air inlet side thereof, one end of the second condenser 70 abuts against the baffle 115, and the other end is connected with the junction of the first air outlet 313 and the second air outlet 333 of the sensible heat exchanger 30.

The end of the baffle 115 away from the first panel 11 may be directly abutted against the end of the inner volute of the cross-flow fan 20 adjacent to the air inlet side thereof, or may be connected by a connection plate.

It can be appreciated that the flow guide plate 115 can guide the air flow flowing out of the sensible heat exchanger 30 from the second air outlet 333 and passing through the second evaporator 50, so that the air flow can smoothly pass through the second condenser 70 and enter the cross flow fan 20, thus effectively reducing wind resistance and improving air quantity, and further improving heat exchange efficiency of the heat exchanger in the dehumidifier 100 and energy efficiency level of the whole machine. In addition, the second condenser 70 is fixed by using the boundary between the first air outlet 313 and the second air outlet 333 of the sensible heat exchanger 30 and the deflector 115, so that the setting stability of the second condenser 70 can be effectively improved, and the working capacity of the second condenser is ensured. Meanwhile, the air flow flowing out of the sensible heat exchanger 30 from the second air outlet 333 and passing through the second evaporator 50 can completely pass through the second condenser 70 and fully contact and exchange heat with the second condenser 70, so that the heat exchange efficiency of the second condenser 70 is improved, the energy consumption of the whole machine is reduced, and the energy efficiency level of the dehumidifier 100 is improved.

In addition, the increase of the air inlet area and the increase of the air quantity can effectively avoid or weaken the surge of the air outlet 171.

As shown in fig. 1 and 4, a fourth air inlet 153 is further formed in the third panel 15 between the baffle 155 and the fourth panel 17, a fourth air path 10d is further formed in the housing 10, the dehumidifier 100 further includes a third condenser 80 disposed in the fourth air path 10d, and the air flow introduced by the fourth air inlet 153 sequentially passes through the third condenser 80 and the cross-flow fan 20 along the fourth air path 10d and is blown out by the air outlet 171.

When the cross flow fan 20 works, the air flow introduced from the fourth air inlet 153 can pass through the third condenser 80 along the fourth air path 10d to complete the heating process, then is converged with the air flow in other air paths, and then passes through the cross flow fan 20 to be blown out from the air outlet 171.

The fourth air inlet 153 and the third condenser 80 corresponding thereto are provided with: on the one hand, the area of the condenser inside the dehumidifier 100 can be effectively increased, so that the heat exchange efficiency (cooling efficiency) of the refrigerant in the condenser is effectively improved, thereby being more beneficial to obtaining low-temperature refrigerant, and further effectively improving the heat exchange efficiency (heating efficiency) of the refrigerant in the first evaporator 40 and the second evaporator 50, namely, the heat exchange efficiency of the first evaporator 40 and the second evaporator 50 is effectively improved, and finally, the power and the energy consumption of the whole dehumidifier 100 are reduced, and the energy efficiency level of the dehumidifier 100 is further improved; on the other hand, the air flow introduced from the fourth air inlet 153 is directly heated and warmed up by the third condenser 80 without being cooled by any evaporator, and the temperature of the air flow is higher than that of the air flows of the first air path 10a and the second air path 10b, and after the air flows are converged, the air outlet temperature of the dehumidifier 100 can be raised, so that the air outlet temperature of the dehumidifier 100 is closer to the room temperature, and the use comfort of a user is ensured. In addition, the air inlet area of the dehumidifier 100 can be increased, the air quantity is increased, and the surging of the air outlet 171 can be effectively avoided or reduced.

Specifically, the third air inlet 113 and the fourth air inlet 153 may be provided with a filter plate (which may be a grid-like structure or other reasonable and effective structure) with a certain porosity, so as to avoid "rushing air" caused to the first air inlet 111 and the second air inlet 151. In addition, when the porosity of the filter plates at the third air inlet 113 and the fourth air inlet 153 is reduced, the air flow is not easy to pass, more air can enter the dehumidifier 100 from the first air inlet 111 and the second air inlet 151, and at this time, more air can be precooled in the second air duct 33 of the heat display exchanger 30; when the porosity of the filter plate at the third air inlet 113 and the fourth air inlet 153 is increased, the air flow is easy to pass, less air can enter the dehumidifier 100 from the first air inlet 111 and the second air inlet 151, but more air can enter the dehumidifier 100 from the third air inlet 113 and the fourth air inlet 153, at this time, although less air is precooled and dehumidified directly, the air inlet is effectively increased, the heat exchange efficiency of the refrigerant is effectively improved, and the heat exchange efficiency of each heat exchanger is effectively improved. It will be appreciated that the porosity ranges from 0 to 1.

As shown in fig. 1 and 4, the inner wall surface of the third panel 15 is further provided with a flow guiding plate 157 in a protruding manner, the flow guiding plate 157 and the baffle 155 are respectively located at two sides of the fourth air inlet 153, and the flow guiding plate 157 extends toward an end of the outer volute of the through-flow fan 20 adjacent to the air inlet side thereof and is connected with an end of the outer volute adjacent to the air inlet side thereof.

The end of the drainage plate 157 away from the third panel 15 may be directly abutted against the end of the outer volute of the cross-flow fan 20 adjacent to the air inlet side thereof, or may be connected by a connection plate.

In this embodiment, the drainage plate 157 is vertically disposed, and the end of the drainage plate 157 facing the third panel 15 is connected to the third panel 15, and the end of the drainage plate 157 away from the third panel 15 is connected to one end of the outer volute of the cross-flow fan 20 adjacent to the air inlet side thereof. It can be appreciated that the flow guiding plate 157 can guide the air introduced from the side of the fourth air inlet 153 far away from the baffle 155, so as to reduce wind resistance and improve air quantity, thereby further improving heat exchange efficiency of the heat exchanger in the dehumidifier 100 and energy efficiency level of the whole dehumidifier.

Further, the third condenser 80 is sandwiched between the drain plate 157 and the baffle 155.

It can be appreciated that the third condenser 80 is fixed by using the drainage plate 157 and the baffle 155, so that the setting stability of the third condenser 80 can be effectively improved, and the working capacity of the third condenser is ensured. Meanwhile, the air flow introduced from the fourth air inlet 153 can completely pass through the third condenser 80 and fully contact and exchange heat with the third condenser 80, so that the heat exchange efficiency of the third condenser 80 is improved, the whole energy consumption is reduced, and the energy efficiency level of the dehumidifier 100 is improved.

At this time, as shown in fig. 1 to 4, the first air inlet 111 and the third air inlet 113 are located at the same side, and both face the air inlet side of the cross flow fan 20; the second air inlet 151 and the fourth air inlet 153 are located on the same side, and the air inlet side of the cross flow fan 20 is opposite to the air inlet side. Thus, uniform air intake in the circumferential direction of the dehumidifier 100 can be realized, so that the heat exchange efficiency of the dehumidifier 100 is further improved, and the energy level of the whole dehumidifier is further improved.

In addition, in order to reduce the difficulty of connection of the heat exchangers and to save costs, the first evaporator 40 and the second evaporator 50 are disposed adjacent to each other, and the first condenser 60, the second condenser 70, and the third condenser 80 are disposed adjacent to each other. In addition, according to the practical requirements, the reasonable positions of the second panel 13, the third panel 15 and the fourth panel 17 can be further provided with an air inlet or an air supplementing opening, so as to improve the air quantity, heat exchange efficiency, power and energy efficiency ratio.
