[0055] In the related art, a condensing assembly is arranged in the shell to condense and remove the moisture of the moisture discharge airflow to generate cooling water. However, the condenser condensate and the generated cooling water are both discharged through corresponding pipelines, which causes the pipelines to be densely arranged, which is not conducive to production assembly.

[0058] The condensing assembly C provided by the application has the following advantages. Since the condenser 3 of the condensing assembly C is arranged in the condensing cavity 2, the humid hot air introduced into the condensing cavity 2 is condensed and absorbed by the condenser 3 to form cooling water, which is drained out through the drain port 21. Since the water outlet of the condenser 3 is arranged in the condensing cavity 2, the condensed water of the condenser 3 is also drained out through the drain port 21. Therefore, the condensed water of the condenser 3 and the cooling water can be drained out through one drain port 21. Accordingly, only one pipeline connected with the drain port 21 needs to be arranged, so as to simplify the pipeline arrangement and improve the production assembly efficiency. The condensing assembly C of the application will be further described below. Figures 3-14 The condensing assembly C of the application will be further described below.

[0071] Since the first positioning groove 55 is formed by the first positioning plate 53, the first side wall 24 and the first support 51, and the air inlet 22 is arranged on the first side wall 24, the condenser 3 can be attached to the first side wall 24, so that the dehumidifying air flow introduced from the air inlet 22 can be introduced into the condenser 3 as much as possible, and the condensing efficiency is improved. In addition, since the second positioning groove 56 is formed by the two second positioning plates 54 and the second support 52, there is a distance between the condenser 3 and the second side wall 25, and the water outlet 31 of the condenser 3 can be arranged obliquely towards the second side wall 25.

In addition, since the dehumidifying channel D3, the condenser 3 and the dehumidifying fan cavity D5 for assembling the dehumidifying fan D33 are all arranged in the shell 1, the dehumidifying fan D33 can be connected with the dehumidifying channel D3 by using the internal structure of the shell 1, and the air tightness requirement can be met without the need of arranging a sealing member, so that the structure is simple and compact, and the production and assembly are facilitated.

When the dehumidified air flow passes through the wheel disc module D1, the moisture in the dehumidified air flow can be absorbed by the wheel disc module D1 and heated by the heating element to generate a dry air flow, which is transported to the drum R to remove the moisture in the drum R. While generating dry air flow, the heating area D61 generates dehumidification air, and the dehumidification fan D33 is started to guide the dehumidification air out through the dehumidification channel D3, thereby forming the above-mentioned dehumidification air flow in the dehumidification channel D3.

[0076] In combination with Figure 5 and Figure 6 , the bottom of the condensation cavity 2 is lower than the outlet end D34 of the dehumidification channel D3, so as to avoid the condensate overflowing into the dehumidification wheel in the shell 1 when the condensate is abnormally discharged, affecting the dehumidification and dehumidification effect of the drying module D. In specific implementation, the part of the bottom of the shell 1 where the condensation cavity 2 is located can be appropriately sunken, or the bottom of the dehumidification channel D3 can be appropriately raised, so that the vertical distance H1 between the bottom of the condensation cavity 2 and the outlet end D34 of the dehumidification channel D3 is between 40-60 mm (as shown in Figure 7 and Figure 8 ), and the vertical distance H1 can be 40 mm, 50 mm, 55 mm or 60 mm.

[0077] In combination with Figures 5-8 , the bottom of the outlet end D34 of the dehumidification channel D3 is provided with a first flow guide part D31, one end of the first flow guide part D31 is connected to the outlet end D34 of the dehumidification channel D3, and the other end of the first flow guide part D31 is connected to the bottom of the air inlet 33, and the height of one end of the first flow guide part D31 is higher than the height of the other end of the first flow guide part D31.

The portion of the first side portion D32 opposite to the portion of the second guide portion D32, and the portion of the second guide portion D32 opposite to the second guide portion D32, are configured as the outlet end D34 of the first dehumidification channel D3. The cross-sectional dimension of the dehumidification channel D3 gradually decreases from the inlet end D35 to the outlet end D34, so that the size of the outlet end D34 of the dehumidification channel D3 is reduced, thereby accelerating the flow of dehumidified airflow to the condensing cavity 2 and improving the condensation efficiency. According to another embodiment of this application, only the cross-sectional dimension of the outlet end D34 of the first dehumidification channel D3 can be reduced, which can also accelerate the flow of dehumidified airflow to the condensing cavity 2.

In a specific implementation, the bottom of the shell 1 can be appropriately sunken at the part of the condensation cavity 2, or the bottom of the moisture removal fan cavity D5 can be appropriately raised, so that a vertical distance H3 between the bottom of the condensation cavity 2 and the bottom of the moisture removal fan cavity D5 is between 40 mm and 60 mm, and the vertical distance H2 can be 40 mm, 50 mm, 55 mm or 60 mm, so that the bottom of the moisture removal fan cavity D5 is substantially at the same height as the bottom of the outlet end D34 of the moisture removal channel D3.

[0085] According to an embodiment of the present application, the bottom of the first flow guide portion D31 can have a height difference with the bottom of the condensation cavity 2, and since the bottom of the moisture removal fan cavity D5 also has a height difference with the bottom of the condensation cavity 2, the bottom of the condensation cavity 2 forms a cavity with a closed peripheral surface, which is used to receive the cooling water generated by the condenser 3. According to another embodiment of the present application, the bottom of the first flow guide portion D31 can also be at the same height as the bottom of the moisture removal fan cavity D5, as long as the inlet end D35 of the condensation cavity 2 is higher than the bottom of the moisture removal channel D3.

[0100] The drying module D provided by the present application can simplify the pipeline connected with the condensing assembly C, and improve the production and assembly efficiency. In addition, since the dehumidifying passage D3, the condenser 3 and the dehumidifying fan cavity D5 for assembling the dehumidifying fan D33 are all arranged in the housing 1, the dehumidifying fan D33 can be connected with the dehumidifying passage D3 by using the internal structure of the housing 1, and the air tightness requirement can be achieved without sealing element, so that the structure is simple and compact, and the production and assembly are facilitated.

[0101] It should be noted that the condensing assembly C of the drying module D can also adopt the technical solution in the related art that the condensing water of the condenser 3 and the generated cooling water are discharged through the corresponding pipeline, or other types of solutions, which are not limited herein. The drying module D of the present application will be further described below in combination with Figure 2 , Figures 5-6 .

When the dehumidifying airflow passes through the wheel disc module D1, the moisture in the dehumidifying airflow can be absorbed by the wheel disc module D1 and heated by the heating element to generate a dry airflow, which is transported to the drum R to remove the moisture in the drum R. At the same time of generating the dry airflow, the dehumidifying air is generated in the heating area D61, the dehumidifying fan D33 is started, and the dehumidifying air is guided out through the dehumidifying passage D3, so that the dehumidifying airflow is formed in the dehumidifying passage D3.

[0103] In combination Figure 5 and Figure 6 , the bottom of the condensation cavity 2 is lower than the outlet end of the dehumidification channel D3, so as to avoid the condensate water overflowing into the dehumidification disc in the shell 1 and affecting the dehumidification and dehumidification effect of the drying module D when the condensate water discharge is abnormal. In specific implementation, the part of the bottom of the shell 1 where the condensation cavity 2 is located can be appropriately sunken, or the bottom of the dehumidification channel D3 can be appropriately raised.

The first flow guide part D31 can be a slope, an arc surface, or a combination of a slope and an arc surface, which is not limited here.

In addition, the extended support part 27 can also limit the displacement of the condenser 3 to prevent the phenomenon that the condenser 3 is separated from the above-mentioned support block due to the vibration generated by the electrical equipment during operation, so as to ensure the normal operation of the condenser 3.

[0106] In combination Figure 5 and Figure 6 , the cross-sectional size of the outlet end of the dehumidification channel D3 is smaller than the cross-sectional size of the remaining part of the dehumidification channel D3, so as to reduce the size of the outlet end of the dehumidification channel D3, so that the dehumidification air flow can accelerate to flow out to the condensation cavity 2, and the condensation efficiency is improved.

[0111] According to an embodiment of the present application, the bottom of the first flow guide portion D31 can have a height difference with the bottom of the condensing cavity 2. Since the bottom of the dehumidifying fan cavity D5 also has a height difference with the bottom of the condensing cavity 2, the bottom of the condensing cavity 2 forms a cavity with a closed peripheral surface, which is used to receive the cooling water generated by the condenser 3. According to another embodiment of the present application, the bottom of the first flow guide portion D31 can also be at the same height as the bottom of the dehumidifying fan cavity D5, as long as the inlet end of the condensing cavity 2 is higher than the bottom of the dehumidifying passage D3.
