Description

Technical Field

[0001] The present invention relates to the field of washing machine control, and in particular to a cleaning device and a washing machine. Background Art

[0002] As people's living standards improve, washing machines are becoming more and more popular, and people are paying more attention to healthy washing. First, people pay more attention to the washing effect of clothes. The full mixing of detergent and water can improve the washing effect of clothes; second, people pay more attention to the cleaning of dirt in the washing machine itself. When the washing machine is running, the washing water flows between the inner and outer barrels of the washing machine and the inner barrel. Dirt is easily accumulated on the outer wall of the inner barrel and the inner wall of the outer barrel, which becomes a hotbed for germs and causes secondary pollution to clothes. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the inner and outer barrels of washing machines are easy to accumulate dirt and difficult to clean, the present invention provides a cleaning device and a washing machine.

[0004] The technical solution adopted by the present invention is:

[0005] The present invention provides a cleaning device, comprising: a water pipeline arranged between an outer barrel and an inner barrel of a washing machine, a plurality of water outlet holes are arranged on a side wall of the water pipeline, and the water pipeline is connected to a water inlet flow path of the washing machine.

[0006] Furthermore, the inlet end of the water pipeline is connected to a three-way pipe, and the other two pipes of the three-way pipe are respectively connected to the detergent box and the water inlet valve, and the water inlet valve is connected to the water inlet flow path of the washing machine. A pressure regulating valve for adjusting the water pressure of the water inlet is provided on the pipe connecting the three-way pipe to the water inlet valve, and a detergent box valve is provided at the connection between the detergent box and the three-way pipe.

[0007] Preferably, the water pipeline is arranged on the inner wall of the outer barrel and is arranged spirally around the inner barrel from top to bottom.

[0008] The present invention also includes a controller for controlling the gear positions and / or switches of various valves in various washing modes of the washing machine.

[0009] When the washing machine operates in a weighing mode, the controller determines the amount of detergent added and the amount of water taken in according to the weighing information.

[0010] When the washing machine is running in the washing mode and / or the rinsing mode, the controller opens the detergent box valve and the water inlet valve, and adjusts the pressure regulating valve to the first preset gear position to determine whether the determined detergent dosage has been reached. If so, the controller closes the detergent box valve and increases the gear position of the pressure regulating valve. After increasing the gear position of the pressure regulating valve, the controller determines whether the water inlet volume determined in the weighing mode has been reached. If so, the water inlet valve and the pressure regulating valve are closed.

[0011] A specific embodiment is as follows:

[0012] When the washing machine is in the washing mode, the controller opens the detergent box valve and the water inlet valve, and adjusts the pressure regulating valve to the first preset gear position to determine whether the determined detergent dosage has been reached. If so, the controller closes the detergent box valve and increases the gear position of the pressure regulating valve. After increasing the gear position of the pressure regulating valve, the controller determines whether the water inlet volume determined in the weighing mode has been reached. If so, the water inlet valve and the pressure regulating valve are closed.

[0013] When the washing machine runs in the rinsing mode, the controller opens the water inlet valve and adjusts the pressure regulating valve to the second preset gear position, and the detergent box valve is closed. When the water inlet volume reaches the water inlet volume determined by the weighing mode, the water inlet valve and the pressure regulating valve are closed.

[0014] When the washing machine runs in dehydration mode and the water level of the washing machine is 0, the controller controls the drain valve of the washing machine to remain open, starts the motor of the inner drum of the washing machine to rotate the inner drum, opens the water inlet valve, adjusts the gear of the pressure regulating valve to the maximum gear or to the third preset gear, and determines whether the preset flushing time is reached. If so, closes the water inlet valve and the pressure regulating valve.

[0015] The present invention also provides a washing machine, comprising the above-mentioned cleaning device.

[0016] Compared with the prior art, the present invention embeds a water pipe with holes in the outer barrel, and sets a water inlet valve, a pressure regulating valve, a three-way pipe, and a detergent box valve to achieve a full mixing of detergent and water, so as to achieve a detergent decontamination effect, and flush water through the water pipe in the washing and rinsing steps, which has a blocking effect on the movement of water, enhances the stirring and surging effect of water, and increases the washing effect of clothes.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, the present invention proposes a cleaning device for a washing machine, comprising: a water pipe 162, the inlet end of the water pipe is connected to the water inlet flow path of the washing machine, the water pipe 162 is arranged at the interval between the outer barrel 16 and the inner barrel 17 of the washing machine, the interval is a mixed flushing area 18 of the water pipe 162, and a certain distance is maintained from the inner barrel 17 to prevent contact with the inner barrel 17 and affect the rotation of the inner barrel, a plurality of water outlet holes 163 are provided on the side wall of the water pipe 162, so that when the water pipe 162 is connected, the outer wall of the inner barrel and the inner wall of the outer barrel can be flushed, and the inner barrel can enhance the flushing effect while rotating, and the water after flushing is discharged from the bottom of the outer barrel from the washing machine to complete the cleaning between the inner and outer barrels of the washing machine.

[0025] In order to improve the cleaning efficiency and facilitate control, the inlet end of the water pipe 162 is connected to the water inlet nozzle 161 provided on the outer barrel, and is connected to a pipe located at the bottom of the three-way pipe 15 through the water inlet nozzle 161. The other two pipes of the three-way pipe 15 are forked upwards, respectively connecting the detergent box and the water inlet valve 11. The water inlet valve 11 is provided on the water inlet flow path of the washing machine. After the water inlet valve 11 is opened, the water on the water inlet flow path can flow to the water pipe 162 through the three-way pipe 15 for flushing, and a pressure regulating valve 14 for adjusting the water pressure of the water inlet is provided on the pipe. The detergent box 12 is provided near the top of the washing machine, and a detergent box valve 13 is provided at the bottom of the detergent box 12. After the detergent box valve 13 is opened, the detergent box is connected to the three-way pipe 15. During washing, the detergent box valve 13 and the water inlet valve 11 are opened at the same time, and both the detergent and water flow downward along the three-way pipe 15 to the water pipe 162. The detergent is driven by the water of the water inlet valve 11 to be sprayed out from the water outlet 163 on the water pipe 162 to rinse the outer wall of the inner barrel and the inner wall of the outer barrel. The detergent and water are mixed and washed during the rinsing process, and the inner barrel can also be kept rotating during washing, so that the mixture of detergent and water is stirred in the mixed rinsing area 18 to further rinse the inner wall of the outer barrel and the outer wall of the inner barrel. After the washing program is completed, the drain valve is opened to discharge the mixed liquid of detergent and water from the drain port at the bottom of the outer barrel out of the washing machine, completing the cleaning between the inner and outer barrels of the washing machine.

[0026] The specific structure of the water pipe 162 can be set in different forms, and as long as the structure can flush the area between the inner and outer barrels, it is within the protection scope of the present invention. Now, an embodiment is specifically described by example.

[0027] like Figure 2 As shown, the water conduit 162 is arranged on the inner side 164 of the outer barrel and is arranged in a spiral shape from top to bottom around the inner barrel. The water outlet holes 163 are evenly arranged on the side of the water conduit 162 facing the outer wall of the inner barrel, and the water conduit 162 can be flat or strip-shaped, with two rows of water outlet holes 163 arranged on it along the length direction.

[0028] The present invention also includes a controller, which can be a controller of the washing machine, or a controller of the cleaning device that can communicate with the controller of the washing machine. By setting the controller to control the switch and gear position of the valve, the cleaning device can automatically run following the washing program.

[0029] like Figure 3 As shown (it should be noted that the water pressures 1, 2, and 3 in the figure correspond to the first, second, and third preset gears), when the washing machine is running in the weighing mode, the controller determines the amount of detergent added to the cleaning device and the amount of water inflow into the water pipe according to the weighing information obtained in the weighing mode. Sensors for detecting the real-time amount of added and the amount of water inflow are already commonly used in the prior art, so they are not specifically described in the present invention.

[0030] When the washing machine is running in washing mode, the controller opens the detergent box valve 13 and the water inlet valve 11, and adjusts the pressure regulating valve 14 to the first preset gear (the first preset gear is the smallest gear) to allow water to flow in with detergent. Because the water inlet valve 11 is connected to the municipal pipeline, the water entering from the water inlet valve 11 flows through the three-way pipe 15 to the water inlet nozzle, which will cause negative pressure in the three-way pipe 15, and the liquid will automatically flow from the side with high pressure to the side with low pressure (siphon effect). Therefore, when the water inlet valve 11 and the detergent box valve 13 are opened, the detergent in the detergent box will be sucked into the three-way pipe 15 and mixed with water to be sprayed out from the water outlet 163 of the water pipeline 162. Because the water flow rate and pressure of the first preset gear are relatively small, it can prevent the water pressure from being too high and causing the water flow to directly rush into the detergent box, and prevent the detergent from being sucked out too quickly, resulting in the inability to accurately judge the amount of detergent added, thereby ensuring the normal introduction of the detergent, and then judging whether the amount of detergent added determined by the weighing mode is reached. If so, the controller closes the detergent box valve 13 and increases the gear of the pressure regulating valve 14 to the second preset gear. If not, the pressure regulating valve 14 continues to maintain this gear to cooperate with the introduction of the detergent.

[0031] After the controller closes the detergent box valve 13 and increases the gear position of the pressure regulating valve 14 , it determines whether the preset water intake volume determined by the weighing mode is met. If so, the water intake valve 11 and the pressure regulating valve 14 are closed.

[0032] Increasing the gear position of the pressure regulating valve 14 can increase the impact force of water in the water pipeline, so that the detergent is mixed with water, and is fully mixed with water under the action of water pressure through the water outlet holes on the water pipeline, and flows into the outer barrel like a waterfall.

[0033] When the washing machine runs in the rinsing mode, the detergent box valve remains closed, the controller opens the water inlet valve, and adjusts the pressure regulating valve to the second preset gear (the second preset gear is greater than the first preset gear) to determine whether the water inlet volume determined by the weighing mode is reached. If so, close the water inlet valve and the pressure regulating valve.

[0034] Moreover, the water pipes have a blocking effect on the movement of water during the washing and rinsing stages, which can enhance the stirring and surging effects of the water and improve the washing effect on the clothes. In other embodiments, detergent can be added only during the rinsing stage, or detergent can be added during the rinsing stage and the washing mode. The specific setting method can be selected according to the degree of dirtiness and actual needs to improve the cleaning efficiency.

[0035] When the washing machine is running in the dehydration mode and the water level of the washing machine is 0, that is, the water in the inner barrel has been emptied, the controller controls the drain valve of the washing machine to remain open, and starts the motor of the inner barrel of the washing machine to rotate the inner barrel, opens the water inlet valve 11, adjusts the gear of the pressure regulating valve 14 to the maximum gear or to the third preset gear for flushing, and determines whether the preset flushing time has been reached. If so, close the water inlet valve 11 and the pressure regulating valve 14, and the motor continues to run. When the preset dehydration time of the washing machine is reached, close the motor again. When the water level of the washing machine is 0, close the drain valve again. By starting the motor to rotate the inner barrel, when the inner barrel rotates, water is ejected from the water outlet of the water pipe under strong water pressure, flushing the outer wall of the inner barrel and the inner wall of the outer barrel, thereby flushing away the dirt remaining on the outer wall of the inner barrel and the inner wall of the outer barrel. Ensure that no dirt remains in the washing machine every time the clothes are washed, and achieve the effect of no secondary pollution of the washing machine.

[0036] The present invention also provides a washing machine, which may be a pulsator washing machine, comprising the above-mentioned cleaning device.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
