DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] See also Figure 1 and Figure 2 The embodiment of the present application provides a filtering device 110, including a first shell 10 and a second shell 20, wherein the first shell 10 is provided with a first air inlet 115, and the second shell 20 is provided with a plurality of filtering micropores 215 arranged at intervals, and the first shell 10 and the second shell 20 are connected by relative rotation, so that the first shell 10 and the second shell 20 can be opened and closed, and when the first shell 10 and the second shell 20 are closed, a filtering space is enclosed between the first shell 10 and the second shell 20.

[0033] The filter device 110 provided in the embodiment of the present application can be installed in the condenser 100 of the washer-dryer, and is used to filter the hair debris in the air circulation system of the washer-dryer, thereby avoiding the problem of the air inlet channel of the drying system being blocked, increasing the air intake volume, and thus improving the drying efficiency and user experience; the first shell 10 and the second shell 20 of the filter device 110 can be opened and closed. When the filter device 110 is needed to filter the hair debris, the first shell 10 and the second shell 20 can be closed and installed in the condenser 100. When a lot of hair debris is collected in the filtering space of the filter device 110, the filter device 110 can be removed from the condenser 100 and the first shell 10 and the second shell 20 can be opened to remove the hair debris accumulated therebetween.

[0034] See also Figure 1 and Figure 2 , the first shell 10 and the second shell 20 are connected by a flexible connector 30. It can be understood that, since the flexible connector 30 has good bending resistance, when the first shell 10 and the second shell 20 are opened or closed, the flexible connector 30 can effectively buffer the stress generated inside itself, thereby realizing the rotation connection between the first shell 10 and the second shell 20.

[0035] Exemplarily, the material of the flexible connector 30 may be an organic polymer, such as PET (polyethylene terephthalate) or the like.

[0036] For example, the number of the flexible connector 30 may be one or more (ie, two or more), see Figure 1 and Figure 2 In some embodiments, the first shell 10 and the second shell 20 are connected by two flexible connectors 30 that are spaced apart.

[0037] See also Figure 1 and Figure 2 The first shell 10 includes a first bottom plate 11 and a first side plate 12 connected to the first bottom plate 11 , and the first bottom plate 11 is provided with a plurality of first air inlets 115 arranged at intervals.

[0038] See also Figure 1 The second shell 20 includes a second bottom plate 21 and a second side plate 22 connected to the second bottom plate 21 , and the second bottom plate 21 is provided with a plurality of filtering micropores 215 arranged at intervals.

[0039] See also Figure 1 The second bottom plate 21 may include multiple filter screens 211, and any two adjacent filter screens 211 are connected by reinforcing ribs 212, both ends of the reinforcing ribs 212 are connected to the second side plate 22, and the edge of each filter screen 211 except the connection area with the reinforcing ribs 212 is connected to the second side plate 22.

[0040] It is understandable that by dividing the second bottom plate 21 into multiple filter screens 211 and using reinforcing ribs 212 to connect adjacent filter screens 211, the mechanical strength of the second bottom plate 21 can be improved, and its service life can be extended, thereby extending the service life of the filter device 110.

[0041] See also Figure 1 and Figure 2When the first shell 10 and the second shell 20 are closed, the side of the first side plate 12 facing away from the first bottom plate 11 abuts against the side of the second side plate 22 facing away from the second bottom plate 21 .

[0042] See also Figure 2 When the first shell 10 and the second shell 20 are closed, the orthographic projection of the first side panel 12 on the first bottom panel 11 / the second bottom panel 21 completely overlaps with the orthographic projection of the second side panel 22 on the first bottom panel 11 / the second bottom panel 21.

[0043] See also Figure 1 and Figure 2 The first side plate 12 in the first shell 10 and the second side plate 22 in the second shell 20 are connected via a flexible connector 30 .

[0044] See also Figure 1 The first air inlet 115 and the filtering micropores 215 can both be circular holes.

[0045] Exemplarily, the diameter of the first air inlet 115 is 1 mm to 3 mm (eg, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.).

[0046] Exemplarily, the diameter of the filtering micropores 215 is 0.1 mm to 0.3 mm (eg, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, etc.).

[0047] See also Figure 1 The first shell 10 also includes a first hook 41 and a second hook 51 connected to the first side plate 12 and spaced apart, and the second shell 20 also includes a third hook 42 and a fourth hook 52 connected to the second side plate 22 and spaced apart.

[0048] See also Figure 2 When the first shell 10 and the second shell 20 are closed, the first hook 41 and the third hook 42 are fitted together to form a first hook assembly 40 , and the second hook 51 and the fourth hook 52 are fitted together to form a second hook assembly 50 .

[0049] See also Figure 1 and Figure 2 The first shell 10 and the second shell 20 may both be triangular in shape. When the first shell 10 and the second shell 20 are closed, the filter device 110 is triangular in shape as a whole, and the first hook assembly 40 and the second hook assembly 50 are respectively located at two vertices of the triangle.

[0050] See also Figures 3 to 6The embodiment of the present application also provides a condenser 100, including a third shell 120 and a filter device 110 arranged in the third shell 120, the third shell 120 has a second air inlet 123 and an air outlet 124, the filter device 110 is arranged in the air inlet channel between the second air inlet 123 and the air outlet 124, and the filter device 110 is the filter device 110 in any of the above embodiments.

[0051] See also Figure 5 The filter device 110 divides the inner cavity of the third shell 120 into a front cavity and a rear cavity.

[0052] See also Figure 4 The condenser 100 further includes a water inlet pipe 130 , which is connected to the third shell 120 , and one end of the water inlet pipe 130 extends into the front cavity of the third shell 120 .

[0053] See also Figure 4 and Figure 6 A plurality of diversion plates are provided in the front cavity of the third shell 120, wherein a diversion plate closest to the water inlet pipe 130 is used to receive the water flow introduced from the water inlet pipe 130 and guide the water flow to the remaining diversion plates, so that the water flow flows on the plurality of diversion plates in sequence, thereby prolonging the time that the water flow stays in the front cavity of the third shell 120.

[0054] It should be noted that the working principle of the condenser 100 of the embodiment of the present application is as follows: cold water with a lower temperature is introduced into the front cavity of the third shell 120 through the water inlet pipe 130. When the water flow reaches the extension plate, it can spread on the extension plate, thereby expanding the contact area between the water flow and the humid hot air entering the condenser 100, and then the water flow with a lower temperature can be used to condense the water vapor in the humid hot air into liquid water. This part of the condensed water is mixed with the water flow and discharged from the bottom of the condenser. Since the water vapor in the humid hot air is reduced, the humidity of the humid hot air is reduced and converted into relatively dry air. The dry air then passes through the filter device 110, and the hair in the air is filtered out by the filter device 110. The filtered air is then discharged from the air outlet 124 of the condenser 100. The air can then enter the drying channel assembly for heating to obtain dry air with a higher temperature. The dry air with a higher temperature can then enter the inner drum of the washer-dryer and contact the wet clothes, thereby drying the clothes.

[0055] It can be understood that the condenser 100 of the embodiment of the present application dries the hot and humid air by utilizing cold water with a lower temperature to condense the water vapor in the hot and humid air. While removing the water vapor in the hot and humid air, this method can also utilize the water flow to adsorb and remove a portion of the dander in the hot and humid air, thereby reducing the dander content in the hot and humid air before the filter device 110 works.

[0056] Exemplarily, the temperature of the cold water used in the condenser 100 of the embodiment of the present application can be 0-15°C, such as 1°C, 3°C, 5°C, 7°C, 10°C, 13°C, 15°C, etc.

[0057] See also Figure 4 and Figure 6 The inner wall of the front cavity of the third shell 120 includes a first side wall 141 and a second side wall 142 arranged opposite to each other, and the multiple flow extension plates include multiple first flow extension plates 151 and multiple second flow extension plates 152. The multiple first flow extension plates 151 are all connected to the first side wall 141 and keep a gap between the second side wall 142. The multiple second flow extension plates 152 are all connected to the second side wall 142 and keep a gap between the first side wall 141. The first flow extension plates 151 and the second flow extension plates 152 are alternately stacked and kept at a gap.

[0058] It can be understood that the structure in which the first flow diversion plate 151 and the second flow diversion plate 152 are alternately stacked can make the water flow alternately on the first flow diversion plate 151 and the second flow diversion plate 152, and ensure that all the first flow diversion plates 151 and the second flow diversion plates 152 are covered with water, thereby maximizing the time for the water flow to stay in the front cavity of the third shell 120 while saving space, that is, the contact time between the water flow and the hot and humid air can be increased, thereby improving the condensation effect of the hot and humid air, and further improving the dryness of the air discharged from the condenser 100.

[0059] See also Figures 3 to 5 The third shell 120 is provided with an opening 171, and the outer surface of the third shell 120 is provided with a boss 172 arranged around the opening 171. The filtering device 110 includes a first hook assembly 40 and a second hook assembly 50 arranged at intervals. The first hook assembly 40 and the second hook assembly 50 are respectively connected to the opposite sides of the boss 172 by hook connection.

[0060] See also Figure 3 and Figure 5It can be understood that the installation and disassembly method of the filter device 110 in the condenser 100 can be: the filter device 110 is placed in the third shell 120 through the opening 171, and the filter device 110 is installed in the condenser 100 by using the hook connection between the first hook assembly 40 and the second hook assembly 50 of the filter device 110 and the boss 172 on the third shell 120. When the filter device 110 needs to be removed to collect the hair debris collected therein, the first hook assembly 40 and the second hook assembly 50 can be lifted upwards, and the filter device 110 can be taken out of the third shell 120 through the opening 171, and then put back in place for continued use after cleaning.

[0061] See also Figure 3 , Figure 5 and Figure 6 The third shell 120 may include a main body 122 and a cover body 121, the main body 122 is provided with the second air inlet 123 and the air outlet 124, the cover body 121 includes a connected third bottom plate 61 and a third side plate 62, the water inlet pipe 130 is connected to the third side plate 62, and the multiple flow extension plates (including multiple first flow extension plates 151 and multiple second flow extension plates 152) are all connected to the third side plate 62.

[0062] See also Figure 6 , a guide plate 160 is further provided in the front cavity of the third shell 120, and the guide plate 160 is provided between the outlet of the water inlet pipe 130 and a diversion plate closest to the water inlet pipe 130, and a plurality of through holes 161 arranged at intervals are provided on the guide plate 160, so that the water flow can pass through the through holes 161 to reach a diversion plate closest to the water inlet pipe 130 and spread on the diversion plate, that is, the guide plate 160 can play a role in uniformly dispersing the water flow, so that the water flow on the surface of the diversion plate closest to the water inlet pipe 130 is evenly dispersed, which is conducive to achieving uniform spreading of the water flow on multiple diversion plates, please refer to Figure 6 The guide plate 160 and a flow extension plate closest to the water inlet pipe 130 can be connected to the same side (ie, the first side wall 141) of the inner wall (ie, the third side plate 62) of the third shell 120.
