Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to a drying component for a cleaning machine and the cleaning machine. Background Art

[0002] A dishwasher is a household appliance used for automatic dishwashing, which is very popular among consumers. However, after washing, there is a lot of residual water in the inner tank and on the dishes. This residual water is dried by the residual heat of the inner tank and the dishes. However, due to the large amount of residual water in the inner tank and the rapid cooling of the inner tank, the residual heat of the inner tank is not enough to evaporate the residual water, so there is still a lot of water in the inner tank for a long time after washing the dishes. If the dishwasher door is closed for a long time, the odor in the dishwasher will be strong and bacteria will easily breed.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN201820319612.0 (publication number CN208958049U) discloses a "drying system for a dishwasher", including an inner tank and a breather, the breather is arranged outside the inner tank, the breather is provided with an exhaust channel, the exhaust channel connects the inside and outside of the inner tank, and also includes a hot air generating device, the hot air generating device is provided with a hot air output end, the hot air output end is connected to the inside of the inner tank, the inner tank is provided with an air duct nut corresponding to the hot air output end, the air duct nut fixes the hot air output end to the inner tank wall, the air duct nut is provided with a hole position, the hole position is connected to the inside of the inner tank and the hot air output end, the hole position includes a central hole and peripheral holes, and the peripheral holes are evenly distributed in a ring shape around the central hole.

[0004] However, the air outlet cross-sectional area of ​​the duct nut (i.e., the airflow guide member hereinafter) is large, resulting in a slow flow rate and a short airflow path, making it impossible to dry the parts of the inner tank that are far away from the duct nut; although the airflow will be dispersed by the holes of the duct nut when passing through the duct nut, the duct nut mainly serves to disperse the airflow and has limited guiding effect on the airflow. As a result, the direction of the airflow after entering the inner tank is disordered, and the overall drying effect in the inner tank needs to be further improved.

[0005] In addition, the exhaust channel of the patent only has an exhaust function, and its function is relatively simple. To address this problem, the Chinese invention patent application with patent number CN201910127515.0 (publication number CN109700409A) discloses "A dishwasher breather and its dishwasher", which includes an upper shell and a lower shell, and a breathing port is provided on the upper shell or the lower shell. The upper shell and the lower shell are fixedly connected to each other, and a water supply channel, a drainage channel, a condensation channel, a first anti-siphon channel, a second anti-siphon channel and a regenerated water chamber that are interconnected are formed inside the two; wherein, a disconnected threaded portion is provided on the inner wall of the breathing port, and is fixedly arranged on the inner tank of the dishwasher through the disconnected threaded portion, and the breathing port is connected to the water supply channel, and / or the drainage channel, and / or the condensation channel, and / or the first anti-siphon channel, and / or the second anti-siphon channel, and / or the regenerated water chamber; the first anti-siphon channel is at least partially located below the water supply channel and passes through below the water supply channel.

[0006] The water inlet siphon of this patent can, on the one hand, relieve pressure to prevent the water supply channel from being blocked and the respirator from being cracked; on the other hand, it can prevent the water in the water supply channel from flowing back. Although theoretically, water will not flow out from the water inlet siphon after cutting through the arc-shaped circuitous channel, a small amount of water will still drip under the action of gravity. Because the water inlet siphon, the atmospheric vent and the respirator are interconnected, the water dripping from the water inlet siphon will enter the inner tank from the respirator. The problem caused by this is that the water flowing into the inner tank is hard water that has not been softened by a water softener. If the hardness of the water is high, on the one hand, scale will form on the surface of the heating device in the dishwasher, which will seriously hinder heat conduction and cause perforating corrosion, leading to damage to the heating element; on the other hand, the surface of the dishwasher and the washed tableware will be dirty, affecting the washing quality of the dishwasher. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a drying component capable of accelerating the flow rate of hot air flow in view of the current status of the prior art.

[0008] The second technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned airflow guide member in view of the current status of the prior art.

[0009] The third technical problem to be solved by the present invention is to provide a cleaning machine capable of preventing water leaking from the siphon port from entering the inner tank in view of the current status of the prior art.

[0010] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a drying component, comprising

[0011] A first shell, wherein the first shell has an air flow channel inside, and the first shell is provided with an air outlet hole in fluid communication with the air flow channel;

[0012] A fan having an air inlet and an air outlet, wherein the air inlet of the fan is in fluid communication with the outside, and the air outlet of the fan is in fluid communication with the air flow channel of the first housing;

[0013] A heating element is arranged in the air flow channel;

[0014] It is characterized in that: it also includes an airflow guide, the airflow guide includes

[0015] A plate body is arranged at the air outlet, and an air inlet hole is arranged on the plate body and is fluidically connected with the air outlet hole;

[0016] The baffle is arranged on the wall surface of the plate body, and the baffle extends toward the air inlet and partially shields the air inlet.

[0017] Preferably, at least the portion of the baffle covering the air inlet is an arc-shaped structure arched in a direction away from the air inlet, so as to reduce energy loss when the air flows through.

[0018] In order to guide the airflow, the air inlet is divided into a first area and a second area, the first area is shielded by a baffle, and a guide plate is provided in the second area, the free end of the guide plate extends to the first area, and there is a gap between the guide plate and the baffle. In this way, the airflow will move along the guide plate, and the design of the guide plate further reduces the flow area of ​​the airflow at the air inlet, so that the flow velocity of the airflow is further increased and the flow path is longer.

[0019] In order to further reduce energy loss when air flows through, the guide plate includes a first portion located in the first area and a second portion located in the second area, and the first portion is in an arc shape arched toward the baffle.

[0020] Preferably, a plurality of guide strips are provided on the second part along the circumference of the air inlet, each of which extends along the flow direction of the airflow, and the guide strips are located downstream of the first part. In this way, the airflow can move along the guide strips extending in different directions, and the guide strips play the role of rectifying and guiding the airflow. The airflow moves in an orderly manner and can flow in multiple directions. If the airflow is a hot airflow, it can dry objects over a large area.

[0021] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a cleaning machine, including an inner tank and the above-mentioned drying component, characterized in that: the first shell is located outside the inner tank and installed on the side wall of the inner tank, the inner tank has a washing chamber, and the side wall of the inner tank is provided with an air inlet fluidly connected to the washing chamber, the air inlet corresponds to the air outlet on the first shell and is fluidly connected, the plate body is located in the inner tank, and the air inlet on the plate body is arranged corresponding to the air inlet, and the flow area of ​​the air inlet after being shielded by the baffle is smaller than the flow area of ​​the air inlet.

[0022] In order to allow the airflow to flow to the lower part of the washing chamber, the baffle shields the upper part of the air inlet when the plate is positioned in the washing chamber. In this way, the airflow can flow downward after entering the air inlet, and because the gas flow rate increases, it can move downward a greater distance. In the case of hot airflow, it can move to the lower part of the washing chamber. At the same time, because the airflow can flow upward, the dishes in the washing chamber can be fully dried.

[0023] In order to release the pressure to balance the pressure inside and outside the inner tank when the pressure in the inner tank is high, a respirator is provided on the outside of the inner tank, and the respirator includes a second shell, and a breathing port and an exhaust port in fluid communication are provided on the second shell. Along the airflow direction, the breathing port is located upstream of the exhaust port, and an exhaust hole in fluid communication with the washing chamber is provided on the side wall of the inner tank. The second shell is arranged outside the inner tank and installed on the side wall of the inner tank. The breathing port is provided on the side wall of the second shell facing the inner tank, and the breathing port is in fluid communication with the exhaust hole. During the tableware drying stage, the hot air flow generated by the drying component enters the inner tank, which can easily cause the pressure in the inner tank to increase. In other words, the high-temperature gas generated when the dishwasher is working causes the air pressure in the inner tank to be too high, and it is necessary to exchange gas with the outside through the respirator to balance the air pressure in the inner tank of the dishwasher. The high-temperature gas in the inner tank is discharged through the breathing port and the exhaust port.

[0024] The technical solution adopted by the present invention to solve the third technical problem is as follows: a water inlet and a water outlet are provided on the second shell, a water flow channel is provided in the second shell to fluidically connect the water inlet and the water outlet, and a siphon port penetrating the wall thickness of the water flow channel is provided on the side wall of the water flow channel;

[0025] The respirator also includes

[0026] A compartment, disposed in the second housing, located beside the water flow channel and in fluid communication with the siphon port;

[0027] A water hole is provided on the side wall of the water flow channel and is in fluid communication with the compartment, the water hole is located below the siphon port, and the water hole is located on the water flow path of the water flowing out of the siphon port;

[0028] The cover plate is arranged at the water hole, and the cover plate can move in a direction away from or close to the water hole, so as to open or close the water hole.

[0029] The cover plate can be translated toward or away from the water hole to open or close the water hole, but this requires the design of a mechanism to drive the cover plate to translate and reset. The structure is simple. The cover plate is arranged in the water flow channel, and one of the walls of the cover plate faces the water flow hole. The upper end of the cover plate is rotatably connected to the side wall of the water flow channel through a pin shaft, and the pin shaft is located above the water flow hole. The lower end of the cover plate is a free end and can move in a direction away from or close to the water flow hole. This method involves fewer components, and only the cover plate and the pin shaft need to be designed. When water enters the water flow channel, it is filled with flowing water. Under the action of water pressure, the cover plate deflects toward the direction close to the water hole and keeps the water hole closed. At this time, water leaked from the siphon port will be stored in the compartment; after water enters the water flow channel, since the water flow channel is occupied by air, the cover plate deflects toward the direction away from the water hole under the action of the pressure of the water in the compartment, thereby opening the water hole, and discharging the water in the compartment into the water flow channel and finally flowing to the water outlet; when water enters the water flow channel again, the cover plate will close the water hole again under the action of water pressure.

[0030] In order to reduce the amount of water leakage at the siphon mouth, the water inlet and the water outlet are both arranged at the bottom of the second shell, and the water flow channel includes an upward channel, a downward channel, a bending channel and a turning channel. The lower end of the upward channel is fluidly connected with the water inlet, the upper end of the upward channel extends upward to be fluidly connected with the bending channel, the other end of the bending channel is fluidly connected with one end of the turning channel, the other end of the turning channel is fluidly connected with the upper end of the downward channel, and the lower end of the downward channel extends downward to be fluidly connected with the water outlet. The bending channel and the turning channel are both in an upwardly arched arc, and the turning channel is arranged side by side below the bending channel, and the siphon mouth is arranged on the bottom wall of the turning channel. Due to the arc structure of the bending channel and the rotating channel, the water flow will be accelerated when passing through, and under the action of centrifugal force, it will pass tangentially through the rotating channel and basically will not flow out from the siphon port, and the siphon port can maintain the function of connecting to the atmosphere; when negative pressure is generated at the water inlet, the water in the water flow channel and the water softener connected thereto will have a tendency to flow back due to siphoning, but because the siphon port is connected to the atmosphere, the air in the atmosphere can enter the rotating channel through the siphon port, balance the negative pressure of the water inlet, and ensure that the water in the water flow channel will not flow back.

[0031] In order to form a compartment in the second shell, a partition is provided in the second shell, the upper end of the partition is connected to the revolving channel, the lower end of the partition is connected to the descending channel, and the partition, the revolving channel and the descending channel together form the compartment. In this way, not only can the side wall of the descending channel be used to reduce the number of components required to form the compartment, but it is also convenient to communicate with the water hole and the siphon port.

[0032] In order to make the water flowing out of the siphon port flow smoothly into the water hole, the partition is inclined from top to bottom toward the descending channel, and the water hole is opened on the side wall of the descending channel from the connection between the side wall and the lower end of the partition, and the siphon port is located directly above the partition. The partition plays a role of diversion, and the water leaking from the siphon port falls on the partition and then flows into the water hole along the partition.

[0033] Preferably, the wall surface of the cover plate facing the water hole is provided with a convex strip, and the lower end of the partition plate is provided with a slot for the convex strip to be locked in, so as to ensure the closing effect of the cover plate on the water hole and prevent water from entering the compartment when water flows into the water channel.

[0034] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention provides a baffle on the plate body, which partially shields the air inlet hole, so that the flow area of ​​the gas through the air inlet hole is reduced, the flow rate is increased, and the flow path of the gas is extended, so that it can contact more objects; when the air flow guide is used in a cleaning machine, because the flow path of the gas is extended, it can contact the inner pot and the tableware in the inner pot over a large area, so that the residual water in the inner pot and on the tableware can be dried, and because the air flow rate is increased, the drying effect is also improved; 2. The present invention designs a compartment and a cover plate in the second shell, and when water enters the water flow channel, it is filled with flowing water. Under the action of water pressure, the cover plate moves toward the direction close to the water hole and keeps the water hole closed. At this time, the water discharged from the siphon port The exposed water will be stored in the compartment; after the water flow channel is filled with water, since the water flow channel is occupied by air, the cover moves in the direction away from the water hole under the pressure of the water stored in the compartment, thereby opening the water hole and discharging the water stored in the compartment into the water flow channel and finally flowing to the water outlet; when the water flow channel is filled with water again, the cover will close the water hole again under the action of water pressure, thus it can be seen that the water leaked from the siphon port will not flow into the breathing port, but will flow into the water flow channel; when the respirator is used on the cleaning machine, it can prevent the water leaked from the siphon port from entering the inner tank, and avoid hard water that has not been softened by the water softener from directly entering the inner tank and generating scale; and integrating the water flow channel on the respirator not only saves space, but also can use the waste heat of the inner tank to heat the water in the water flow channel.

[0052] The present invention is further described in detail below with reference to the accompanying drawings.

[0053] like Figures 1 to 3As shown, the cleaning machine of this preferred embodiment includes an inner tank 1, a drying component, a respirator A and a water softener (not shown in the figure), the drying component includes an airflow guide 2 and a heating component 3, the inner tank 1 has a washing chamber 11 inside, the inner tank 1 is provided with an air inlet 12 in fluid communication with the washing chamber 11, the airflow guide 2 includes a plate 21, the plate 21 is provided with an air inlet 22 penetrating the wall thickness thereof, the plate 21 is located in the washing chamber 11, and the air inlet 22 on the plate 21 can be in fluid communication with the air inlet 12 on the inner tank 1. In this way, the airflow entering from the air inlet 12 on the inner tank 1 enters the washing chamber 11 through the air inlet 22.

[0054] like Figures 1 to 7 As shown, the heating component 3 includes a first shell 31, a fan 32 and a heating element 33. The first shell 31 has an air flow channel 34 inside, and the first shell 31 is provided with an air outlet 35 which is fluidly connected to the air flow channel 34. The fan 32 has an air inlet 321 and an air outlet 322. The air inlet 321 of the fan 32 is fluidly connected to the outside, and the air outlet 322 of the fan 32 is fluidly connected to the air flow channel 34 of the first shell 31. The heating element 33 is arranged in the air flow channel 34, and the heating element 33 can be a PTC resistance heating element or other heating elements.

[0055] The first shell 31 is located outside the inner liner 1 and is installed on the side wall of the inner liner 1. The air inlet 12 on the inner liner 1 corresponds to the air outlet 35 on the first shell 31 and is fluidically connected. The plate body 21 is located in the inner liner 1, and the air inlet 22 on the plate body 21 is arranged corresponding to the air inlet 12.

[0056] In order to realize the positioning of the airflow guide 2, the inner liner 1 and the first shell 31, as shown in FIG. Figure 3 , 10 As shown, the plate body 21 is provided with an annular body 23 surrounding the outer periphery of the air inlet hole 22, and a threaded portion 231 is provided on the outer wall surface of the annular body 23. The annular body 23 passes through the air inlet 12 and is threadedly connected to the air outlet hole 35; and the periphery of the plate body 21 is extended along its axial direction to form an annular portion 24, and the annular portion 24 is located at the outer periphery of the annular body 23. When the annular body 23 is threadedly connected to the first shell 31, the annular portion 24 can press the side wall of the inner liner 1 against the first shell 31. A gasket 12 can be designed between the inner liner 1 and the first shell 31 to prevent hard contact between the two, and it can also play a sealing role.

[0057] like Figures 8 to 10As shown, a baffle 25 extending toward the air inlet 22 and partially shielding the air inlet 22 is provided on the wall of the plate body 21. In this embodiment, the baffle 25 and the annular body 23 are respectively arranged on two opposite walls of the plate body 21, that is, the baffle 25 is arranged on the wall of the air flow channel 34 of the plate body 21 away from the first shell 31, and at least the part of the baffle 25 covering the air inlet 22 is an arc-shaped structure arched in the direction away from the air inlet 22, so that the energy loss of the air flow can be reduced when the air flow passes through. Of course, the baffle 25 can also be designed as an arc-shaped structure as a whole. As can be seen from the above, the air outlet 35 on the first shell 31, the air inlet 12 on the liner 1 and the air inlet 22 on the plate body 21 are arranged in sequence and connected to each other. Because the baffle 25 partially shields the air inlet 22, the flow area of ​​the air inlet 22 shielded by the baffle 25 is smaller than the flow area of ​​the air inlet 12. The flow area refers to the area through which the corresponding hole / opening can provide airflow. The larger the flow area, the greater the airflow; the smaller the flow area, the smaller the airflow.

[0058] The air inlet 22 is divided into a first area and a second area. The first area is shielded by the baffle 25. The second area is provided with a guide plate 26. The free end of the guide plate 26 extends to the first area, that is, the baffle 25 and the guide plate 26 partially overlap in the axial direction of the air inlet 22, and there is a gap between the guide plate 26 and the baffle 25. In this way, the airflow moves along the guide plate 26, and the flow path is as follows: Fig.10 As shown by the middle arrow, the design of the guide plate 26 further reduces the flow area of ​​the airflow at the air inlet 22, so that the flow velocity of the airflow is further increased and the flow path is longer.

[0059] like Figure 3 As shown, when the airflow guide 2 is positioned relative to the inner container 1 and the first housing 31, the baffle 25 shields the upper part of the air inlet 22. In this way, the airflow can flow downward after entering the air inlet 22, and because the gas flow rate increases, it can move downward a greater distance. At the same time, because the airflow can flow upward, the tableware in the washing chamber 11 can be fully dried.

[0060] In this embodiment, the guide plate 26 includes a first portion 261 located in the first area and a second portion 262 located in the second area. The first portion 261 is in an arc shape that arches toward the baffle 25 to reduce the energy loss of the airflow. A plurality of guide strips 2620 are provided on the second portion 262 along the circumference of the air inlet 22. Each guide strip 2620 extends along the flow direction of the airflow, and the guide strip 2620 is located downstream of the first portion 261. In this way, the airflow can move along the guide strips 2620 extending in different directions. The guide strips 2620 play the role of rectification and diversion. The airflow moves in an orderly manner and can be dispersed in multiple directions, thereby drying objects over a large area.

[0061] The periphery of the baffle plate 25 includes a first side edge 251 connected to the plate body 21 and a second side edge 252 facing the air inlet hole 22, and the periphery of the guide plate 26 includes a third side edge 263 connected to the plate body 21 and a fourth side edge 264 facing the air inlet hole 22. The first side edge 251 and the third side edge 263 are arranged opposite to each other in the circumferential direction of the air inlet hole 22, the first side edge 251 is located in the first area, the third side edge 263 is located in the second area, and the fourth side edge 264 extends to the first area. In this way, the baffle plate 25 and the guide plate 26 can achieve the best cooperation to guide and rectify the airflow.

[0062] like Figure 1 , 11 As shown in Figures 1 to 17, the respirator A includes a second shell 2a, which is formed by two half shells. The second shell 2a is arranged outside the inner liner 1 and installed on the side wall of the inner liner 1. The side wall of the inner liner 1 is provided with an exhaust hole 13 in fluid communication with the washing chamber 11. The side wall of the second shell 2a facing the inner liner 1 is provided with a breathing port 21a, and the breathing port 21a is in fluid communication with the exhaust hole 13. The second shell 2a is also provided with an exhaust port 22a. The second shell 2a is provided with an airflow channel 23a connecting the exhaust port 22a and the breathing port 21a. Along the airflow direction, the breathing port 21a is located upstream of the exhaust port 22a. During the tableware drying stage, the hot air flow enters the inner liner 1, which can easily cause the pressure in the inner liner 1 to increase. In other words, the high-temperature gas generated when the dishwasher is working causes the air pressure in the inner tank 1 to be too high, and it is necessary to exchange gas with the outside through the respirator A to balance the air pressure in the inner tank 1 of the dishwasher, so that the high-temperature gas in the inner tank 1 flows out through the breathing port 21a, the air flow channel 23a and the exhaust port 22a in sequence. An exhaust fan 3a is provided in the air flow channel 23a, and the air inlet of the exhaust fan 3a is fluidly connected to the breathing port 21a, and the air outlet of the exhaust fan 3a is fluidly connected to the exhaust port 22a to accelerate the discharge of the high-temperature gas. The exhaust fan 3a can adopt the structure of the existing technology.

[0063] The bottom of the second shell 2a is provided with a water inlet 24a and a water outlet 25a. The water inlet 24a is in fluid communication with an external water source, and the water outlet 25a is in fluid communication with the water inlet hole of the water softener. After being softened by the water softener, the water enters the washing chamber 11 of the inner tank 1 to wash the tableware, fruits and vegetables in the washing chamber 11. Otherwise, the water directly enters the washing chamber 11 without being softened. If the hardness of the water is high, on the one hand, it will cause scale to form on the surface of the heating device in the washing machine, which will seriously hinder heat conduction and cause perforation corrosion, resulting in damage to the heating element; on the other hand, it will make the surface of the washing machine and the tableware after washing not clean, affecting the washing quality of the washing machine. The water softener can adopt an existing structure, such as the "A Water Softener 6 and Dishwasher" disclosed in the Chinese Utility Model Patent No. CN202022a097007.3 (Announcement No. CN214017448U).

[0064] A water flow channel 26a is provided in the second shell 2a, and the water flow channel 26a fluidly connects the water inlet 24a and the water outlet 25a. A water flow meter 265 is provided in the water flow channel 26a, and the water flow meter 265 can adopt the structure of the existing technology. In this embodiment, the water flow channel 26a includes an upward channel 261a, a downward channel 262a, a bending channel 263a and a rotating channel 264a. The lower end of the upward channel 261a is fluidly connected to the water inlet 24a, the upper end of the upward channel 261a extends upward to be fluidly connected to the bending channel 263a, the other end of the bending channel 263a is fluidly connected to one end of the rotating channel 264a, the other end of the rotating channel 264a is fluidly connected to the upper end of the downward channel 262a, and the lower end of the downward channel 262a extends downward to be fluidly connected to the water outlet 25a. The bending channel 263a and the rotating channel 264a are both in an arc shape that arches upward, and the rotating channel 264a is arranged side by side below the bending channel 263a. The bottom wall of the rotating channel 264a is provided with a siphon port 2641 that penetrates its wall thickness, such as Fig.17 shown.

[0065] Due to the arc structure of the bending channel 263a and the rotating channel 264a, the water flow will be accelerated when passing through, and under the action of centrifugal force, it will pass tangentially through the rotating channel 264a, and basically will not flow out from the siphon port 2641, and the siphon port 2641 can maintain the function of connecting to the atmosphere; when negative pressure is generated at the water inlet 24a, the water in the water flow channel 26a and the water softener connected thereto will have a tendency to flow back due to siphoning, but because the siphon port 2641 is connected to the atmosphere, the air in the atmosphere can enter the rotating channel 264a through the siphon port 2641, balancing the negative pressure of the water inlet 24a and ensuring that the water in the water flow channel 26a will not flow back; or if the water flow channel 26a is blocked, the siphon port 2641 can release pressure to prevent the second shell 2a from being blown up.

[0066] However, a small amount of water will still leak out from the siphon port 2641. If the leaked water flows directly into the inner tank 1 from the breathing port 21a, scale will be generated if the water is hard. Fig.13 , 14 As shown in Figures 15, the second shell 2a is also provided with a compartment 27 located beside the water flow channel 26a and fluidically connected to the siphon port 2641. The compartment 27 in this embodiment is surrounded by the following manner: a partition 28 is provided in the second shell 2a, the upper end of the partition 28 is connected to the rotation channel 264a, and the lower end of the partition 28 is connected to the downward channel 262a. The partition 28, the rotation channel 264a and the downward channel 262a together form the compartment 27.

[0067] The partition 28 is inclined from top to bottom toward the descending channel 262a, and a water hole 2621 is provided on the side wall of the descending channel 262a from the connection between the partition 28 and the lower end thereof, and the water hole 2621 is located below the siphon port 2641, and the siphon port 2641 is located directly above the partition 28, so that the siphon port 2641 and the water hole 2621 are both in fluid communication with the compartment 27. The partition 28 plays a role of diversion, and the water leaking from the siphon port 2641 falls on the partition 28, and then flows into the water hole 2621 along the partition 28, that is, the water hole 2621 is located on the water flow path of the water flowing out from the siphon port 2641.

[0068] A cover plate 5 is provided in the descending channel 262a, one of the walls of the cover plate 5 faces the water hole 2621, the upper end of the cover plate 5 is rotatably connected to the side wall of the descending channel 262a via a pin 51, the pin 51 is located above the water hole 2621, and the lower end of the cover plate 5 is a free end and can move away from or toward the water hole 2621. Of course, the cover plate 5 can open and close the water hole 2621 in a non-rotating manner, and can also open and close the water hole 2621 in a translational manner toward or away from the water hole 2621.

[0069] like Fig.15 As shown, when water flows into the water channel 26a, it is filled with flowing water. Under the action of water pressure, the cover plate 5 deflects toward the direction close to the water hole 2621 and keeps the water hole 2621 closed. At this time, the water leaked from the siphon port 2641 will be stored in the compartment 27. After the water flows into the water channel 26a, since the water flow channel 26a is occupied by air, the cover plate 5 deflects toward the direction away from the water hole 2621 under the action of the water pressure in the compartment 27, thereby opening the water hole 2621. Fig.14As shown, the water in the compartment 27 is discharged into the water flow channel 26a and finally flows to the water outlet 25a, so that the water leaking from the siphon port 2641 can be prevented from entering the inner tank 1, and the hard water that has not been softened by the water softener can be prevented from directly entering the inner tank 1 and generating scale; when the water flow channel 26a is filled with water again, the cover plate 5 will close the water hole 2621 again under the action of water pressure. The water flow path in the water flow channel 26a is as shown in FIG. Fig.16 As shown in path A in FIG. 1 , the water flow path of the water leaking from the siphon port 2641 is as follows Fig.16 As shown in path B.

[0070] like Fig.14 As shown, a convex strip 52 is provided on the wall surface of the cover plate 5 facing the water hole 2621, and a slot 282 is provided at the lower end of the partition plate 28 for the convex strip 52 to be clamped therein, thereby ensuring the closing effect of the cover plate 5 on the water hole 2621 and preventing water from entering the compartment 27 when water enters the water flow channel 26a.

[0071] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts, which are collectively referred to as the first part and the second part respectively below, that is, fluid gas, liquid or a mixture of the two can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
