Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a drying filter cleaning mechanism for a washing machine and a washing machine. Background Art

[0002] In current integrated washing machines or dryers, the fan motor sends hot air into the drum after heating by the heating tube, and the steam in the drum is condensed by the condenser tube, and then the air is returned to form a cycle. However, in this process, the fine fluff washed off the clothes will adhere to the fan motor blades or the return air filter without a filter, blocking the entire drying system.

[0003] The prior art has a solution to solve the above problem by manually disassembling the drying system and cleaning it or by adding a water inlet valve to flush the filter. However, in the above solution of manually disassembling the drying system and cleaning it, since the attachment of fluff cannot be avoided, the entire drying channel system is still easily blocked, causing the fan motor to be unable to effectively supply air, thereby causing the drying heating tube to heat up, and the heat cannot be quickly transferred away, causing the drying protection device to reach the action temperature and then perform protection, and the drying cannot be completed. Therefore, manual disassembly and cleaning must be performed frequently, which is time-consuming and labor-intensive; if a clean water inlet is added specifically for flushing, although the effect of cleaning the drying filter can be achieved, the amount of clean water required will increase, which will increase the cost. Utility Model Content

[0004] The utility model provides a method in which washing water is led to the position of a drying filter screen for washing, so that the fluff attached to the drying filter screen is taken away by the water flow, thereby achieving the effect of cleaning the drying filter screen.

DETAILED DESCRIPTION

[0021] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0022] To achieve the above purpose, the embodiments of the present invention adopt the following technical solutions:

[0023] Embodiment 1:

[0024] Reference Figure 1 A drying filter cleaning mechanism for a washing machine comprises an outer drum 10, a drying filter 20 arranged on the side wall of the outer drum, a drainage component and a cleaning component. The drying filter 20 is used to filter the air to enter the drying channel when the washing machine is drying, and filter out the fine fluff washed from the clothes; the drainage component of the washing machine is arranged at the outer drum drainage port 110, and is used to discharge the washing water from the outer drum.

[0025] In this embodiment, one end of the cleaning component is connected to the inner cavity of the outer drum, and the other end is connected to the drying filter 20. The cleaning component is used to drive the washing water in the inner cavity of the outer drum to flow to the drying filter, that is, the cleaning component is used to guide the washing water in the inner cavity of the outer drum to the drying filter 20, and use the washing water to rinse the drying filter. For example, in each rinsing process, the washing water in the inner drum can be guided to the position of the drying filter through the cleaning component, and the water flow rinses the drying filter. After rinsing, the water flow carrying the above-mentioned fine fluff passes through the inner drum pores and the return air duct and returns to the inner drum. Therefore, the fluff attached to the drying filter after the last washing and drying can be rinsed clean in this washing process, ensuring a smooth drying cycle and the washing machine will not be blocked by the drying channel.

[0026] The drying filter cleaning mechanism for the washing machine of this embodiment can use the cleaning component to clean the drying filter during each washing and rinsing process, thereby getting rid of the original manual disassembly and cleaning work and avoiding the need to increase the water intake for a special rinse. In actual products, a circulating rinse of washing water can be set in each rinsing program, so the drying filter will be rinsed each time, which will reduce the risk of the drying filter being blocked and the risk of subsequent abnormal drying alarms of the whole machine.

[0027] As an optional technical solution of this embodiment, the drainage assembly may further include a water outlet hose 310, which is arranged at the outer drum drain port 110, and a drainage pump 320 is connected to the water outlet hose 310. After the washing work is completed, the drainage pump leads the washing water in the inner drum out of the outer drum 10 through the water outlet hose. Further, the output end of the drainage pump 320 may be provided with a drainage pipe port 321, which is used to connect an external drainage pipe, so as to discharge the washing water from the inside of the whole machine to the outside through the external drainage pipe.

[0028] In this embodiment, in order to monitor the water quality of the washing water discharged from the outer tub 10 , a stain sensor 330 may be further provided on the water outlet hose 310 .

[0029] In order to cope with sudden power outages and other emergencies, there is too much water in the washing machine and the door cannot be opened normally. In order to drain the water in the washing machine, a residual water pipe 322 is provided at the water outlet of the drain pump 320. The residual water pipe can drain the water that cannot be discharged from the washing machine due to emergencies; in addition, sometimes due to water vapor mixing in the water pump and the water pump torque being certain, the water cannot be drained. At this time, the residual water pipe can be used to temporarily drain the water and deflate the air.

[0030] In this embodiment, the drainage component is used to discharge the washing water from the outer drum, and as an optional solution, the cleaning component of this embodiment can be arranged to be connected to the output end of the drainage component to avoid opening too many water blowing channels on the outer drum 10 of the washing machine. In this way, in each washing process, the washing water is led out of the outer drum 10 by the drainage component, and then the washing water is led to the drying filter 20 by the cleaning component, so as to achieve the effect of cleaning the drying filter.

[0031] In actual products, the cleaning assembly in this embodiment is used as a directional driving member for directing washing water to the drying filter, and it can generally include a water pipe connected to the inner cavity of the outer drum, and a water pump driving water to flow in the water pipe. In order to improve the cleaning effect of the washing water output by the water pipe on the drying filter, the water outlet of the water pipe in this embodiment faces the surface of the drying filter 20.

[0032] Regarding the water pipe, it can be set at any position in the inner cavity of the outer drum where washing water can be drawn. However, in order to extract washing water in the inner cavity of the outer drum, a corresponding water outlet must exist in the inner cavity of the outer drum; and in the present embodiment, in order to avoid opening too many water outlets on the outer drum 10 of the washing machine, as a preferred technical solution of the present embodiment, the cleaning component may include a circulating pump 410 arranged at the outer drum drain port 110, and the output end of the circulating pump is connected to a circulating pipe 420, and the end of the circulating pipe away from the circulating pump is connected to the drying filter 20; and the water outlet of the circulating pipe 420 faces the surface of the drying filter 20.

[0033] In this way, the washing water discharged from the outer drum to the outer drum drain port 110 reaches the drying filter 20 along the circulation pipe 420 under the action of the circulation pump, thereby realizing the circulation of the washing water in the outer drum 10 and the drying filter 20. When the washing water reaches the drying filter 20 through the water outlet of the circulation pipe 420, the fluff attached to the drying filter is rinsed.

[0034] Specifically, the circulation pump 410 of this embodiment can be arranged on the water outlet hose 310 to be connected with the outer drum drain outlet 110, and the circulation pump is arranged between the drain pump 320 and the outer drum drain outlet 110 on the pipeline. In this way, the circulation pump is connected with the water outlet hose 310, and the washing water discharged through the water outlet hose 310 can enter the circulation pump 410 and reach the drying filter 20 through the circulation pipe 420.

[0035] When the washing machine is running the washing and rinsing programs, the washing water in the outer drum enters the circulation pump through the water outlet hose, and enters the circulation pipe through the circulation pump, and is led to the position of the drying filter through the water outlet of the circulation pipe. The washing water rinses the drying filter to achieve the purpose of cleaning. In this way, the drying filter can be cleaned during each washing and rinsing process, and the fluff attached to the drying filter will be rinsed and carried away by the water flow. In this way, after the washing and rinsing are completed, the drying filter is also cleaned simultaneously, which has the effect of cleaning the drying filter without increasing additional clean water intake, and at the same time gets rid of the original work of manually disassembling and cleaning the drying filter.

[0036] It should be noted that the cleaning component in the present application document, on the one hand, can be a completely new component on the existing washing machine product, such as adding the aforementioned circulation pump 410 and circulation pipe 420 to the washing machine; on the other hand, it can also partially utilize the existing structure in the washing machine product, such as the following embodiment 2.

[0037] Embodiment 2:

[0038] Reference Figure 2 The implementation scheme of this embodiment is basically the same as that of the above-mentioned embodiment 1, with the difference being that a branch water pipe 421 for circulating spraying is arranged on the circulation pipe 420 in this embodiment.

[0039] As a circulating spray system well known to those skilled in the art, it may include a circulating water pump and a circulating spray pipe. In the prior art, a washing machine provided with a circulating spray system can, during the washing process, the water outlet end of the circulating spray pipe can circulate and spray washing water onto the clothes in the inner barrel of the washing machine. The specific structure and function of the circulating water pump and the circulating spray pipe are not described in detail herein.

[0040] In the present embodiment, a branch water pipe 421 for circulating spraying is arranged on the circulation pipe 420, the circulation pump 420 can be used as a circulating water pump in a circulating spraying system, and the front section of the circulation pipe 420 and the branch water pipe 421 can be used as circulating water pipes in a circulating spraying system to achieve a circulating spraying effect in a washing procedure; wherein, the scheme of how to set the water outlet end of the branch water pipe 421 in the inner drum to achieve a spraying effect belongs to a known technology and will not be described in detail herein.

[0041] In summary, compared with embodiment 1, this embodiment also has a circulating spray washing effect. In this embodiment, when the circulating pump 410 is working, the washing water can be directed to the branch water pipe 421 and the drying filter 20 at the same time, so that the spray washing and the rinsing and drying filter 20 can be performed simultaneously.

[0042] It should be noted that when the water output of the circulation pump 410 is directed to the branch water pipe 421 and the drying filter 20 respectively, the energy of the water flow for circulating spraying and the water flow for flushing the drying filter will be reduced, affecting the effect of circulating spraying and the effect of flushing the drying filter. Therefore, in this embodiment, a switching valve 430 can also be set on the circulation pipe 420, and the switching valve 430 is used to switch the water pumped out by the circulation pump 410 between the branch water pipe 421 and the drying filter 20. That is, the switching valve can control the water pumped out by the circulation pump 410 to be directed to the branch water pipe 421 for circulating spraying, and can also control the water pumped out by the circulation pump 410 to be directed to the drying filter 20 for flushing.
