[0029] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection or can communicate with each other; it can be directly connected, or indirectly connected through intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The present application provides a washing machine to solve the problem that the drain bellows is easy to produce peculiar smell. The following will be described with reference to the accompanying drawings.

[0030] In the embodiments of the present application, as shown in the washing machine, the washing machine comprises a washing tub 1, a detection module, a sterilization module and a control module; the washing tub 1 is communicated with a drain pipe 15; the detection module is used for detecting the turbidity in the drain pipe 15; the control module is electrically connected with the sterilization module and the detection module, and the control module is used for controlling the sterilization module to perform sterilization treatment on the drain pipe 15 based on the turbidity detected by the detection module. Figure 1

[0031] It should be noted that the control module refers to a functional module capable of processing, analyzing, judging and deciding countermeasures and issuing control instructions for signals from the detection module, mainly including a controller. The turbidity refers to the degree of hindrance of the object (mainly water, detergent and clothing fiber impurities, etc.) in the drain pipe 15 to the light. The control module is electrically connected with the sterilization module and the detection module, which means that the control module is connected with the sterilization module and the detection module through entity lines such as wires or wire lines which can transmit electrical signals.

[0032] It can be understood that by setting the detection module which can detect the turbidity in the drain pipe 15, the degree of dirt in the drain pipe 15 is known, and then the sterilization module is used to perform sterilization treatment on the drain pipe 15, thereby solving the peculiar smell problem caused by the growth of bacteria in the drain pipe 15. At the same time, when the drain pump on the drain pipe is not turned on, since the drain pipe is communicated with the washing tub, the sterilization module can also play a sterilization role on the washing water and rinsing water in the washing tub, thereby sterilizing the clothes.

[0033] Specifically, the detection module is used for collecting the turbidity parameters in the drain pipe 15 and sending the parameters to the control module in the form of electrical signals, the control module processes the electrical signals of the detection module, and compares with the preset value of the control module, when it is higher than or equal to the preset value, the sterilization module is controlled to perform sterilization treatment, when it is lower than the preset value, the sterilization module is controlled to be closed. The preset value here refers to the turbidity.

[0034] In some embodiments, as shown in Figure 2 , Figure 3 and​Figure 4 As shown, the sterilization module comprises an electrolysis device 2 for electrolyzing the liquid in the drain pipe 15.

[0035] It should be noted that the electrolysis device 2 is used to electrolyze the liquid in the drain pipe 15, which means that the water in the drain pipe 15 can be electrolyzed to produce hydrogen peroxide, which can kill various microorganisms such as bacteria, fungi, spores and viruses, and has a high sterilization effect. Here, the liquid in the drain pipe mainly refers to washing water, rinsing water and residual water in the drain pipe.

[0036] In some embodiments, as shown in Figure 4 The electrolysis device 2 comprises two electrode sheets electrically connected to each other, which are spaced apart and located at the bending part of the drain pipe 15.

[0037] It should be noted that the bending part of the drain pipe 15 refers to the bending of the drain pipe 15 when it is laid to adapt to the position of the water pump, and the bending part is very easy to leave impurities, so the electrode sheet is arranged at the bending part to better sterilize the microorganisms breeding in the impurities and improve the sterilization effect. The bending part of the drain pipe 15 can also refer to the position of the corrugated structure of the drain pipe 15. The two electrode sheets are an anode electrode sheet and a cathode electrode sheet. After the electrolysis device 2 is powered on, water molecules near the electrode sheets react chemically to obtain hydrogen peroxide. It should be noted that the two electrode sheets cannot be indirectly connected by an object, otherwise a path will be formed, so that hydrogen peroxide cannot be generated.

[0038] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 The washing machine 1 comprises an outer tub 11 and an inner tub 12 located in the outer tub 11. The inner tub 12 is spaced apart from the inner wall of the outer tub 11 to form a drain cavity 14, and the drain cavity 14 is in communication with the drain pipe 15. One end of the inner tub 12 is rotationally connected to one end of the outer tub 11, and the other end of the outer tub 11 is provided with a door seal 13. The door seal 13 is provided with a drain port 132 in communication with the drain cavity 14. The door seal 13 is provided with a washing pipe 16 in communication with the drain port 132, and the washing pipe 16 is also used to communicate with a water source.

[0039] It should be noted that the present application mainly aims at a drum-type washing machine, that is, the rotating shaft of the inner tub 12 of the washing machine is horizontally arranged. The door seal 13 is provided with a washing pipe 16 in communication with the drain port 132, and the washing pipe 16 is also used to communicate with a water source. This means that the washing pipe 16 can wash the drain pipe 15 with clean water source.

[0040] Understandably, after prolonged use, some impurities may remain between the two electrode plates, causing them to become conductive. The clean water flowing through the rinsing pipe 16 can remove these impurities, thus ensuring the normal electrolysis function of the electrolysis device 2. This water source can be the existing water supply to the washing machine, or an additional water source can be connected. Specifically, the rinsing pipe 16 can be turned on after the washing machine has completed its washing and rinsing cycles.

[0041] In some embodiments, such as Figure 8 As shown, the door seal 13 is provided with a groove 131 extending circumferentially thereon, and the drain outlet 132 is provided on the side wall of the groove 131.

[0042] In some embodiments, such as Figure 4 As shown, two electrode plates are located at one end of the drain pipe 15 near the drain cavity 14 and are oriented toward the drain cavity 14.

[0043] Understandably, by placing the electrode plates close to the drain chamber 14, water can be electrolyzed from the inlet of the drain pipe 15. The generated hydrogen peroxide can flow with the water through the entire drain pipe 15, thus providing comprehensive sterilization and achieving better sterilization results. By placing the electrode plates towards the drain chamber 14, the water flowing into the drain pipe 15 impacts the electrode plates, and all the mechanical energy of the water flow acts on the electrode plates, quickly carrying away impurities between the two electrode plates.

[0044] In some embodiments, such as Figure 4 As shown, the drain outlet 132 is located near the lower side of the door seal 13, the first end of the flushing pipe 16 is connected to the upper side of the door seal 13, and the end of the drain pipe 15 connected to the drain cavity 14 is located near the door seal 13.

[0045] It is understandable that by connecting the first end of the flushing pipe 16 to the upper side of the door seal 13, the gravitational potential energy of the water in the flushing pipe 16 is increased, thereby enhancing the impact force of the water flowing through the drain pipe 15. At the same time, the end of the drain pipe 15 that connects to the drain chamber 14 is positioned close to the door seal 13, so that the water flowing into the drain chamber 14 can quickly enter the drain pipe 15 with greater kinetic energy.

[0046] In some embodiments, the washing machine further includes a water inlet valve and a water inlet pipe. The water inlet valve has a water inlet and two water outlets. The water inlet is used to communicate with a water source, and the two water outlets are respectively connected to the second end of the water inlet pipe and the rinsing pipe 16. The water inlet pipe is also used to communicate with the inner tub 12.

[0047] It should be noted that the inlet valve and inlet pipe are structures used to add water to the inner tank 12. Understandably, by using existing piping, a water source can be provided to the flushing pipe 16 by adding a water outlet to the inlet valve.

[0048] In some embodiments, the control module is further configured to control the opening or closing of the water inlet between the water inlet and the two water outlets. When the washing machine is in the washing process, the water inlet is opened to the water outlet connected to the water inlet pipe, and when the washing process is completed, the water inlet is opened to the water outlet connected to the rinsing pipe 16.

[0049] In some embodiments, as shown in Figure 4 The detection module includes a turbidity sensor 3, at least part of the turbidity sensor 3 is arranged in the drain pipe 15.

[0050] It should be noted that at least part of the turbidity sensor 3 arranged in the drain pipe 15 means that the part of the turbidity sensor 3 having the detection function is located in the drain pipe 15.

[0051] Specifically, the turbidity sensor 3 includes a probe 31 and a connector 32 electrically connected to each other, the probe 31 is used to detect the turbidity in the drain pipe 15, and the connector 32 is used to be electrically connected to the control module. Specifically, the two probes 31 are arranged at a relative distance, one of the probes 31 is used to emit light to the other probe 31, and the other probe 31 is used to receive the light. The impurities in the drain pipe 15 will affect the amount of light received, so as to know the turbidity of the liquid in the drain pipe 15 based on this. The connector 32 sends the signal of the received light to the control module. Then at least part of the turbidity sensor 3 arranged in the drain pipe 15 means that the two probes 31 of the turbidity sensor 3 are located in the drain pipe 15.

[0052] In some embodiments, as shown in Figure 4 The area between the two probes 31 is arranged towards the drain cavity 14. It can be understood that if one of the probes 31 is located on the side away from the drain cavity 14 of the other probe 31, the probe 31 will block the water flow, making it difficult for the water flow to pass between the two probes 31. The arrangement of the present embodiment can ensure that the water flow can pass smoothly between the two probes 31, thereby improving the detection sensitivity of the turbidity sensor 3. At the same time, the water flow passing between the two probes 31 can also carry away the dirt on the probes 31, improving the detection accuracy. Here, the water flow can be washing water, rinsing water or clean water flow brought by the rinsing pipe 16.

[0053] In some embodiments, as shown in Figure 4 At least part of the sterilization module is located below the turbidity sensor 3.

[0054] It should be noted that at least part of the sterilization module means the part having the sterilization function. It can be understood that by arranging the turbidity sensor 3 above the sterilization module, the turbidity in the drain pipe 15 can be fed back to the control module more timely, so as to perform sterilization treatment.

[0055] In some embodiments, the sterilization module comprises one or more of an ozone generator, a UV sterilizer, and a silver ion sterilizer. The sterilization purpose can also be achieved by the above-mentioned ways, and the various ways can be used in combination to meet different cleaning requirements.

[0056] In some embodiments, the turbidity sensor 3 and the sterilization module are arranged on the sidewall of the drain pipe 15 opposite to each other, and the turbidity sensor 3 is arranged above the electrolytic device 2 at intervals. In this way, not only can the turbidity in the drain pipe 15 be fed back to the control module more timely, but also the water flow passing through the electrolytic device 2 can be prevented from being blocked by the turbidity sensor 3, so as to ensure that the electrolytic device 2 can generate sufficient hydrogen peroxide.
