DETAILED DESCRIPTION

[0054] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0055] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 1 It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. Figure 1 For reference, the direction indicated by arrow R1 in the figure is the up-down direction.

[0056] In the description of the embodiments of the present application, Figure 2 For reference, the direction indicated by arrow R2 in the figure is the front-to-back direction.

[0057] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the reasons why the sewage pump has the risk of being entangled in the related art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0058] In the related art, the sewage of the clothing treatment equipment will be more or less mixed with lint and other debris dropped from the clothes. Taking the clothes dryer as an example, the airflow used to treat the clothes often carries lint and other debris after flowing through the clothes in the clothing treatment drum. The airflow used to treat the clothes circulates in the clothing treatment equipment, and the lint and other debris carried in the airflow will adhere to the corresponding parts. The lint and other debris attached to these parts need to be cleaned off, and the sewage formed by cleaning the lint and other debris needs to be discharged. In the prior art, the sewage is usually directly sucked by a sewage pump, and the sewage is discharged through the sewage pump. The lint and other debris in the sewage will be entangled on the pump blades of the sewage pump when flowing through the sewage pump, which will hinder the rotation of the pump blades of the sewage pump to a certain extent, and may affect the normal operation of the sewage pump.

[0059] In view of this, the present application embodiment provides a clothes processing device, please refer to Figures 1 to 8 The clothes processing device includes a housing assembly 100, a host 200 and a sewage system. The host 200 is installed on the housing assembly 100, and the host 200 is used to process clothes. The sewage system is connected to the housing assembly 100, and the sewage system is used to receive sewage discharged by the host 200.

[0060] In one embodiment, the clothes treating device may be a clothes dryer.

[0061] In one embodiment, please refer to Figure 1 to Figure 6 The host 200 includes a laundry processing drum 201, and the laundry processing drum 201 is installed on the housing assembly 100. The laundry processing drum 201 is used to process the laundry.

[0062] In one embodiment, please refer to Figure 1 to Figure 6 The host 200 further includes a filter device 202, which is mounted on the housing assembly 100. The airflow for treating clothes circulates between the filter device 202 and the clothes treatment drum 201. In such a structural form, since the airflow for treating clothes circulates between the filter device 202 and the clothes treatment drum 201, the airflow flows through the clothes in the clothes treatment drum 201, so that the airflow carries the fluff and other debris of the clothes. The airflow flowing out of the clothes treatment drum 201 flows through the filter device 202, and the fluff and other debris in the airflow flowing through the filter device 202 is filtered out by the filter device 202, thereby reducing the influence of the fluff and other debris in the airflow on the parts through which the subsequent airflow flows.

[0063] It is understandable that the fluff and other debris filtered out by the filter device 202 will adhere to the filter device 202, and the filter device 202 needs to be cleaned to remove the fluff and other debris on the filter device 202. In one embodiment, the sewage system is used to receive sewage discharged by cleaning the filter device 202.

[0064] In one embodiment, please refer to Figure 2 The host 200 further includes a heat exchanger 203, which is mounted on the housing assembly 100. The airflow for treating clothes circulates between the clothes treatment tub 201 and the heat exchanger 203. In this structural form, the airflow flowing out of the clothes treatment tub 201 is heated by the heat exchanger 203, and the hot airflow flowing out of the heat exchanger 203 enters the clothes treatment tub 201 to dry the clothes in the clothes treatment tub 201.

[0065] It is understandable that, during the process of the airflow for treating clothes circulating between the clothes treating drum 201 and the heat exchanger 203, some of the fluff and other debris carried in the airflow may adhere to the heat exchanger 203, and the heat exchanger 203 needs to be cleaned. In one embodiment, the sewage discharge system is used to receive sewage discharged from the heat exchanger 203 after cleaning.

[0066] In one embodiment, please refer to Figure 2 The heat exchanger 203 includes an evaporator 2031 and a condenser 2032, both of which are mounted on the housing assembly 100, and the air used to process the clothes circulates in sequence between the clothes processing tub 201, the evaporator 2031, and the condenser 2032. In this structural form, the airflow from the clothes processing tub 201 flows through the evaporator 2031 and the condenser 2032 in sequence to form a hot airflow, and then flows back to the clothes processing tub 201 to dry the clothes in the clothes processing tub 201.

[0067] It is understandable that the airflow from the laundry treatment tub 201 first flows through the evaporator 2031 and then flows through the condenser 2032. A lot of lint and other debris may be attached to the evaporator 2031, and the evaporator 2031 needs to be cleaned. In one embodiment, the sewage system is used to receive sewage discharged from the evaporator 2031 for cleaning.

[0068] In one embodiment, please refer to Figure 1 to Figure 5 The airflow for treating the clothes circulates among the clothes treating drum 201, the filtering device 202 and the heat exchanger 203 in sequence.

[0069] In one embodiment, please refer to Figure 1 to Figure 5 The airflow for treating the clothes circulates among the clothes treating drum 201, the filtering device 202, the evaporator 2031 and the condenser 2032 in sequence.

[0070] For the sewage system of the present application embodiment, please refer to Figure 1 , Figure 2 , Figure 5 ,as well as Figure 7 to Figure 10The sewage system includes a water storage container 1, a sewage tank 2 and a sewage pump 3. The water storage container 1 is formed with a water storage tank 11 for accommodating sewage. The sewage tank 2 is formed with a sewage chamber 21 and a water inlet 22, a water outlet 23 and a negative pressure suction port 24 connected to the sewage chamber 21. The sewage tank 2 is connected to the water storage container 1 at the water inlet 22 to receive the sewage in the water storage container 1, and the water outlet 23 is used to discharge the sewage in the sewage chamber 21. The sewage pump 3 is connected to the sewage tank 2, and the sewage pump 3 is used to suck the sewage chamber 21 through the negative pressure suction port 24 to form a negative pressure in the sewage chamber 21. With such a structural form, the sewage chamber 21 is formed with negative pressure through the vacuum suction of the sewage pump 3 to suck the sewage in the water tank 11 into the sewage chamber 21 of the sewage tank 2. However, the sewage in the sewage chamber 21 is not discharged through the sewage pump 3, but is discharged from the water outlet 23 of the sewage tank 2. Since the sewage does not flow through the sewage pump 3, the fluff in the sewage will not flow through the sewage pump 3 either, thereby reducing the risk of the pump blades of the sewage pump 3 being entangled by fluff and other debris and affecting the normal operation of the sewage pump 3.

[0071] In one embodiment, when sewage is stored in the water tank 11 of the water storage container 1, the sewage pump 3 sucks the sewage chamber 21 through the negative pressure suction port 24 to form a negative pressure in the sewage chamber 21, and the sewage in the water tank 11 enters the sewage chamber from the water tank 11 through the water inlet 22 under the action of the negative pressure.

[0072] In one embodiment, the sewage in the sewage chamber 21 can be discharged from the water outlet 23 under the action of gravity.

[0073] In one embodiment, after the sewage pump 3 stops pumping the sewage chamber 21 , the sewage in the sewage chamber 21 can be discharged from the water outlet 23 by pressurizing the sewage chamber 21 .

[0074] In one embodiment, during the suction process of the sewage pump 3 , the water level in the sewage chamber 21 is lower than the position of the negative pressure suction port 24 to prevent the sewage in the sewage chamber 21 from being sucked into the sewage pump 3 through the negative pressure suction port 24 .

[0075] In one embodiment, please refer to Figure 7 to Figure 10 The water storage container 1 and the sewage tank 2 are both connected to the housing assembly 100, and the water storage container 1 is used to receive sewage discharged from the host 200. In this structural form, the water storage container 1 and the sewage tank 2 are both connected to the housing assembly 100, so that the water storage container 1 and the sewage pump are arranged more reasonably in the clothes processing device.

[0076] In one embodiment, please refer to Figure 2 and Figure 5 The water storage container 1 is used to receive the sewage discharged from the cleaning filter device 202 and / or the heat exchanger 203.

[0077] In one embodiment, please refer to Figure 2 and Figure 5 The water storage container 1 is used to receive the sewage discharged from the cleaning filter device 202 and / or the evaporator 2031.

[0078] In one embodiment, please refer to Figures 9 to 13 The sewage tank 2 includes a main tank assembly 26 , a sewage chamber 21 , a water inlet 22 , a water outlet 23 and a negative pressure suction port 24 are all formed in the main tank assembly 26 , and the water storage container 1 and the sewage pump 3 are both connected to the main tank assembly 26 .

[0079] In one embodiment, please refer to Figures 11 to 17 The sewage tank 2 further includes a one-way valve 27, which is installed on the main tank assembly 26 to open or close the water outlet 23. The one-way valve 27 can be in a state of opening the water outlet 23 to discharge the sewage in the sewage chamber 21. When the sewage pump 3 sucks the sewage chamber 21 through the negative pressure suction port 24, the one-way valve 27 is in a state of closing the water outlet 23. In such a structural form, when the sewage pump 3 sucks the sewage chamber 21 through the negative pressure suction port 24, the one-way valve 27 closes the water outlet 23, and the sewage chamber 21 is roughly in a relatively closed state. The sewage pump 3 sucks the sewage chamber 21 to form a negative pressure, so that the sewage in the storage tank is sucked into the sewage chamber 21 under the action of the negative pressure. When the sewage pump 3 stops sucking the sewage chamber 21, the one-way valve 27 opens the water outlet 23, and the sewage in the sewage chamber 21 is discharged from the water outlet 23 under the action of gravity. Through the one-way valve 27, the state of opening or closing the water outlet 23 of the one-way valve 27 can be switched correspondingly to the action of the sewage pump 3 sucking the sewage chamber 21 to form a negative pressure in the sewage chamber 21. The state of opening or closing the water outlet 23 of the one-way valve 27 is related to the suction force of the sewage pump 3, and the operation of sewage suction and sewage discharge can be completed relatively smoothly.

[0080] In one embodiment, the one-way valve 27 may not be provided depending on the situation, and the water outlet 23 is always in an open state, and the sewage is discharged from the water outlet 23 after being sucked into the sewage chamber 21 .

[0081] In one embodiment, when the water outlet 23 is always in an open state, the negative pressure suction force of the sewage pump 3 can be increased.

[0082] In one embodiment, when the water outlet 23 is always in an open state, the water outlet 23 can be set to an appropriate size so that the sewage pump 3 can suck the sewage chamber 21 to form a negative pressure to suck the water in the water tank 11 into the sewage chamber 21 and discharge it from the water outlet 23.

[0083] In one embodiment, a solenoid valve or a manual valve may be used to open or close the water outlet 23 .

[0084] It is understandable that the specific structural form of the one-way valve 27 is not limited, as long as it can open the water outlet 23 to discharge the sewage in the sewage chamber 21 and close the water outlet 23 when the sewage pump 3 performs negative pressure suction on the sewage chamber 21.

[0085] In one embodiment, the one-way valve 27 may be a normally open valve, which closes the water outlet 23 when the sewage pump 3 pumps the sewage chamber 21 .

[0086] In one embodiment, please refer to Figure 13 to Figure 17 The one-way valve 27 includes a mounting pipe 271 and a sealing plug 272. The mounting pipe 271 is connected to the main box assembly 26. The mounting pipe 271 has a drainage chamber 2711, a mounting chamber 2712 and a step surface 2713. The drainage chamber 2711 is connected to the water outlet 23. The mounting chamber 2712 is located at one end of the drainage chamber 2711 away from the water outlet 23. The step surface 2713 is located at one end of the mounting chamber 2712 facing the drainage chamber 2711. The sealing plug 272 is located in the mounting chamber 2712. When the sewage chamber 21 forms a negative pressure, the sealing plug 272 abuts against the step surface 2713, and the sealing plug 272 is in a state of closing the water outlet 23. When the sewage pump 3 stops pumping the sewage chamber 21, the sealing plug 272 is separated from the step surface 2713, and the sealing plug 272 is in a state of opening the water outlet 23. With such a structural form, the sealing plug 272 in the mounting chamber 2712 corresponds to the suction action of the sewage pump 3. When the sewage pump 3 sucks the sewage chamber 21, a certain negative pressure suction force is formed in the sewage chamber 21 to absorb the plug 272 so that the plug 272 abuts against the step surface 2713, and the water outlet 23 and the drainage chamber 2711 are isolated from the installation chamber 2712, thereby closing the water outlet 23. When the sewage pump 3 stops sucking the sewage chamber 21, the gravity of the sewage in the sewage chamber 21 acts on the plug 272 and the plug 272 is affected by its own gravity, so that the plug 272 will move down and away from the step surface 2713, so that the plug 272 is in a state of opening the water outlet 23, and the sewage is discharged from the water outlet 23.

[0087] In one embodiment, please refer to Fig.15 , the step surface 2713 faces the installation cavity 2712.

[0088] In one embodiment, the sealing plug 272 may be made of a flexible material, for example, rubber or silicone.

[0089] In one embodiment, please refer to Figure 14 to Figure 17The mounting tube 271 forms a limiting portion 2714, and the limiting portion 2714 is located below the sealing plug 272 to prevent the sealing plug 272 from being separated from the mounting cavity 2712. In this structural form, since the limiting portion 2714 is located below the sealing plug 272, the displacement of the sealing plug 272 moving downward is limited, and the sealing plug 272 can be prevented from being separated from the mounting cavity 2712. Under the influence of repeated suction and stopping of suction by the sewage pump 3, the sealing plug 272 can repeatedly open or close the water outlet 23, so that sewage is discharged from the water outlet 23.

[0090] In one embodiment, please refer to Fig.14 The distance between the stopper 2714 and the step surface 2713 along the axial direction of the mounting tube 271 is greater than the axial dimension of the sealing plug 272 along the axial direction of the mounting tube 271. In this way, the sealing plug 272 installed on the mounting tube 271 has enough space to move to open or close the water outlet 23.

[0091] In one embodiment, please refer to Figure 11 to Figure 14 ,as well as Fig.16 The sewage tank 2 includes a drain pipe 28 installed at the water outlet of the one-way valve 27. With such a structural form, the sewage discharged from the one-way valve 27 can be guided to a suitable location for discharge through the drain pipe 28. When the one-way valve 27 needs to be maintained, the drain pipe 28 is removed from the one-way valve 27, and the maintenance personnel can maintain the one-way valve 27 more conveniently.

[0092] In one embodiment, the drain pipe 28 is detachably connected to the one-way valve 27 .

[0093] In one embodiment, the drain pipe 28 is detachably connected to the mounting pipe 271 .

[0094] Exemplarily, the detachable connection may be in various forms such as flange connection or threaded connection.

[0095] It is understandable that the plug 272 is easily worn out and needs to be replaced due to repeated movement of the plug 272. When the plug 272 needs to be replaced, the drain pipe 28 can be removed from the mounting pipe 271 of the one-way valve 27, and the maintenance personnel can easily replace the plug 272 in the mounting cavity 2712 at the bottom of the mounting pipe 271.

[0096] In one embodiment, please refer to Figure 10 to Figure 13 ,as well as Fig.16The main box assembly 26 also includes a box body 261 and a water inlet pipe 262. The sewage chamber 21, the water inlet 22, the water outlet 23 and the negative pressure suction port 24 are all formed in the box body 261, and the sewage pump 3 is connected to the negative pressure suction port 24 of the box body 261. One end of the water inlet pipe 262 is connected to the water inlet 22 of the box body 261, and the other end of the water inlet pipe 262 is connected to the water storage container 1. In this structural form, the water inlet pipe 262 is connected to the box body 261 and the water storage container 1 respectively. By adapting a more suitable water inlet pipe 262, the box body 261 can be located at an appropriate position relative to the water storage container 1, which is convenient for the installation of the box body 261.

[0097] In one embodiment, please refer to Fig.10 The water inlet pipe 262 is partially located in the water storage tank 11 of the water storage container 1.

[0098] In one embodiment, the sewage pump 3 may also be connected to the water inlet pipe 262. The sewage pump 3 pumps the water inlet pipe 262 to suck the water in the water storage tank 11 into the water inlet pipe 262 and pump it to a certain height. The water in the water inlet pipe 262 pumped to a certain height by the sewage pump 3 can fall into the sewage cavity 21 of the box body 261 through the water inlet 22 under the action of gravity.

[0099] In one embodiment, please refer to Fig.13 The water outlet 23 is located at the bottom of the sewage chamber 21, and the bottom surface 25 of the sewage chamber 21 gradually tilts downward along the direction of the water outlet 23 from any position on the bottom surface 25 of the sewage chamber 21. In such a structural form, since the bottom surface 25 of the sewage chamber 21 gradually tilts toward the water outlet 23, the water in the sewage tank will gradually gather toward the water outlet 23 under the action of gravity, which is conducive to the water in the sewage chamber 21 being discharged from the water outlet 23.

[0100] It should be explained that the bottom surface 25 of the sewage chamber 21 gradually slopes downward, which means that the height of the bottom surface 25 of the sewage chamber 21 gradually decreases.

[0101] It is understandable that the bottom surface 25 of the sewage chamber 21 is not limited to gradually inclining toward the water outlet 23. In one embodiment, the heights of various positions on the bottom surface 25 of the sewage chamber 21 can be the same, that is, the bottom surface 25 of the sewage chamber 21 is substantially horizontal.

[0102] In one embodiment, please refer to Fig.13 The positions of the water outlet 23 and the water inlet 22 are both lower than the position of the negative pressure suction port 24. With such a structural form, the sewage entering the sewage tank from the water inlet 22 will basically not enter the sewage pump 3 from the negative pressure suction port 24 due to the suction effect of the sewage pump 3, thereby reducing the risk of the pump blades of the sewage pump 3 being entangled by fluff and other debris.

[0103] In one embodiment, the position of the negative pressure suction port 24 can be slightly lower than the position of the water inlet 22 as appropriate, as long as the water level in the sewage chamber 21 is lower than the position of the negative pressure suction port 24 .

[0104] In one embodiment, please refer to Fig.13 The negative pressure suction port 24 and the water inlet 22 are both located above the water outlet 23 .

[0105] In one embodiment, please refer to Figure 11 to Figure 13 ,as well as Fig.16 The sewage system further includes a mounting base 4, which is connected to the sewage tank 2, and a sewage pump 3 is mounted on the mounting base 4. With such a structural form, the sewage pump 3 can be supported relatively stably by the mounting base 4, and the mounting base 4 is connected to the sewage tank 2, so that the sewage pump 3 is installed close to the sewage tank 2, and the connecting pipe between the sewage pump 3 and the sewage tank 2 can be set shorter, which is conducive to reducing the pressure loss along the way when the sewage pump 3 sucks the sewage tank.

[0106] It is understandable that the sewage pump 3 is not necessarily installed on the mounting base 4 connected to the sewage tank 2. Any method is possible as long as the sewage pump 3 can be well mounted and fixed.

[0107] In one embodiment, please refer to Figure 7 , Figure 8 as well as Fig.10 The water storage container 1 includes a container body 12 and a mounting cover 13.

The guide surface 101 gradually tilts downward along the direction from the filter device 202 to the water tank 11. The water tank 11 and the filter device 202 are located at the same end of the laundry treatment drum 201. With such a structural form, the distance between the water tank 11 and the filter device 202 is relatively close, and for approximately the same height difference, the angle between the guide surface 101 and the horizontal direction can be increased, which is conducive to the smooth flow of lint and other debris in the sewage on the guide surface 101 and toward the water tank 11.

[0110] In one embodiment, please refer to Figure 1 to Figure 5 The water storage tank 11 and the filtering device 202 are both located at the front end of the clothing processing tub 201 along the axial direction.

The sewage after cleaning the filter assembly 2022 is discharged from the sewage discharge channel 2026. In such a structural form, the airflow flowing out of the clothing treatment drum 201 flows into the filter assembly 2022 through the air intake channel 2025 for filtration. After the filter assembly 2022 filters out the fluff and other debris in the airflow, the airflow flows out from the rear shell 2023. After being filtered by the filter assembly 2022, the content of the fluff and other debris in the airflow is reduced. The sewage used to clean the filter assembly 2022 can flow out from the sewage channel 2026 to avoid the accumulation of sewage in the filter device 202.
