DETAILED DESCRIPTION

[0037] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] like Figures 1 to 7 The pumping assembly 23 according to the embodiment of the present application is used in a household appliance, and includes a pump housing 231, wherein the pump housing 231 has a quantitative cavity 2301 and a first opening 2302 and a second opening 2303 connected to the quantitative cavity 2301. The first quantitative cavity 2301 and the second quantitative cavity 2301 can allow fluid to flow in and out.

[0039] The pumping assembly 23 further includes a switch member 232 and a driving member 233. The switch member 232 is connected to the pump housing 231 and has a first state and a second state. The switch member 232 closes the first opening 2302 and opens the second opening 2303 in the first state, and opens the first opening 2302 and closes the second opening 2303 in the second state. The driving member 233 is connected to the switch member 232.

[0040] The first opening 2302 can be set to allow fluid to flow in, and the second opening 2303 can be set to allow fluid to flow out; the first opening 2302 can also be set to allow fluid to flow out, and the second opening 2303 can be set to allow fluid to flow in. In the following description of the present application, the first opening 2302 is mainly used for fluid to flow in, and the second opening 2303 is used for fluid to flow out. This is not intended to limit the scope of protection of the present application.

[0041] Specifically, when the switch 232 is in the second state, the first opening 2302 is opened and the second opening 2303 is closed. At this time, the consumable will flow from the first opening 2302 into the quantitative cavity 2301 and fill the quantitative cavity 2301; then the switch is switched to the first state, at which time the first opening 2302 is closed and the second opening 2303 is opened, and the fluid will be discharged from the second opening 2303, thereby achieving the purpose of pumping the consumable.

[0042] Among them, since the consumables flow from the first opening 2302 into the quantitative chamber 2301 and are collected, they will remain in the quantitative chamber 2301. Therefore, when the first opening 2302 is opened and the second opening 2303 is closed, only a predetermined amount of consumables can be put into the quantitative chamber 2301; and when the first opening 2302 is closed and the second opening 2303 is opened, since the first opening 2302 is closed, the consumables will not be able to enter the quantitative chamber 2301 through the first opening 2302, and the consumables in the quantitative chamber 2301 will also be discharged through the second opening 2303. At this time, the discharge amount of the second opening 2303 can only be the amount of consumables retained in the quantitative chamber 2301. Therefore, through the pumping component 23, the predetermined amount of consumables can be put.

[0043] According to the pumping component 23 of the embodiment of the present application, its structure is simple, and only the switch member 232 is required to open and close the first opening 2302 and the second opening 2303. In addition, during the pumping process, the limitation of the quantitative chamber 2301 can be utilized. During a cycle of one state switching of the switch member 232, only a predetermined amount of consumables can be delivered. When more consumables need to be delivered, it is only necessary to switch the state of the switch member 232 multiple times. Therefore, the pumping component 23 of the present application can well deliver the consumables in a quantitative manner.

[0044] The present application is particularly suitable for the delivery of rinse aid in the dishwasher 100. Since the rinse aid has a low viscosity, it can smoothly flow into and out of the washing chamber 101, thereby achieving quantitative delivery of consumables. Of course, the pumping assembly 23 in the present application can also be used for delivery of other types of consumables.

[0045] The present application can allow the fluid to flow into the quantitative cavity by opening the first opening 2302 and closing the second opening 2303; and allow the fluid to flow out of the quantitative cavity by opening the second opening 2303 and closing the first opening 2302. Quantitative delivery of consumables is achieved, wherein the opening and closing of the first opening 2302 and the second opening 2303 can be adopted in a variety of ways. For example, a first closing portion is provided to open and close the first opening 2302; a second closing portion is provided to open and close the second opening 2303. For another example, a closing portion is provided to open and close the first opening 2302 and the second opening 2303. The first opening 2302 and the second opening 2303 of the present application can be arranged at different positions on the pump housing 231, for example, the first opening 2302 and the second opening 2303 are arranged on the same side wall or on different side walls on the pump housing 231. The first opening 2302 and the second opening 2303 may be arranged on opposite side walls of the pump housing 231; the first opening 2302 and the second opening 2303 may also be arranged on adjacent side walls of the pump housing 231; the first opening 2302 and the second opening 2303 may also be arranged on the same side wall of the pump housing 231. In addition, the switch element 232 in the present application may be one or more, for example, two switch elements 232 are arranged to open and close the first opening 2302 and the second opening 2303 respectively; for another example, one opening is arranged to open and close the first opening 2302 and the second opening 2303, etc. The present application will be described in detail below, which is not intended to limit the scope of protection of the present application.

[0046] like Figure 3 , Figure 5 and Figure 6 The present application provides some embodiments, in which the first opening 2302 and the second opening 2303 are arranged opposite to each other, and the switch member 232 includes a blocking portion, which is configured to reciprocate between the first opening 2302 and the second opening 2303. In this way, the state of opening the first opening 2302 and opening the second opening 2303 can be switched by reciprocating the blocking portion, so that the switch member 232 switches between the first state and the second state, with a simple structure and convenient control.

[0047] like Figure 3In some embodiments, the blocking portion includes a plug 2321, which is partially inserted into the first opening 2302 in the first state and blocks the first opening 2302. By partially inserting the plug 2321 into the first opening 2302, the plug 2321 can effectively block the first opening 2302, thereby improving the blocking effect of the first opening 2302. In combination with the above, the first opening 2302 can be set as an inlet for the consumables to flow into the quantitative chamber 2301, and the plug 2321 can improve the blocking effect of the first opening 2302. When the consumables do not need to be delivered, the effective blocking of the plug 2321 can also ensure the stability of the pumping assembly 23, thereby avoiding the misdelivery of the consumables.

[0048] The peripheral wall of the first opening 2302 at one end close to the second opening 2303 is provided with an annular groove 2304. That is, a portion of the plug 2321 is inserted into the first opening 2302, and another portion is inserted into the annular groove 2304. The annular groove 2304 can provide a space for the plug 2321, so that the plug 2321 can be better inserted into the first opening 2302, thereby improving the sealing effect of the plug 2321 on the first opening 2302.

[0049] In addition, if Figure 3 and Figure 7 , the plug 2321 can also be configured as a pointed shape with a size gradually increasing in the direction from the first opening 2302 to the second opening 2303, with a portion of the plug 2321 having a size smaller than the first opening 2302, and another portion having a size larger than the first opening 2302. In this way, at least a portion of the peripheral wall of the plug 2321 can be set as a conical surface structure, so that after a portion of the plug 2321 is inserted into the first opening 2302, the other portion will provide a good closure for the first opening 2302, thereby improving the closure effect of the first opening 2302. In addition, in combination with the above, an annular groove 2304 is provided at one end of the first opening 2302, so that the portion not inserted into the first opening 2302 can extend into the annular groove 2304, thereby providing a better closure effect for the first opening 2302.

[0050] Combination Figures 3 to 7In some embodiments, the blocking portion further includes a skirt 2322, which extends along the circumference of the switch member 232. The skirt 2322 is stacked on the periphery of the second opening 2303 in the second state, and the second opening 2303 is sealed by the skirt 2322. The second opening 2303 can be stably sealed by the skirt 2322, and when the consumable enters the quantitative cavity 2301, pressure can be provided to the skirt 2322 to achieve better sealing of the second opening 2303, thereby preventing the consumable in the quantitative cavity 2301 from being sent out from the second opening 2303 during the process of the consumable entering the first opening 2302, thereby effectively improving the stability of the delivery assembly 20 and optimizing the precision of quantitative delivery.

[0051] The skirt 2322 is closer to the second opening 2303 than the plug 2321. Thus, when the switch member 232 moves toward the first opening 2302, the plug 2321 can be inserted into the first opening 2302 to achieve stable closure of the first opening 2302; and when the switch member 232 moves toward the second opening 2303, the plug 2321 can release the closure of the first opening 2302 and open the first opening 2302 when the skirt 2322 closes the second opening 2303. Thus, the switch member 232 can close the first opening 2302 in the first state and the second opening 2303 in the second state.

[0052] In addition, if Figure 2 and Figure 3 The skirt 2322 can be set to an annular sheet shape and constructed to be inclined in the direction from the first opening 2302 to the second opening 2303 from the inside to the outside. In this way, the skirt 2322 can have a certain degree of deformability. When the skirt 2322 approaches the second opening 2303, the periphery of the skirt 2322 will first fit with the periphery of the second opening 2303, and as the switch member 232 moves, the other surfaces of the skirt 2322 gradually fit with the periphery of the second opening 2303, and the second opening 2303 can be quickly closed to limit the amount of consumables flowing into the quantitative chamber 2301 from the first opening 2302. At the same time, the consumables that flowed into the quantitative chamber 2301 in the previous cycle of the switch member 232 can also be discharged, thereby effectively improving the consumable delivery accuracy of the pumping assembly 23 and realizing the quantitative delivery of consumables.

[0053] Combination Figure 3 and Figure 7In some embodiments, the switch member 232 further includes a connecting portion 2323, which is disposed through the second opening 2303 and connected to the blocking portion. The connecting portion 2323 can be connected to the driving member 233, so that the driving member 233 and the connecting portion 2323 drive the switch member 232 to reciprocate, effectively improving the stability of the pumping assembly 23, simplifying the structure of the pumping assembly 23, and reducing the failure rate of the pumping assembly 23.

[0054] In addition, the switch member 232 may further include ribs 2324, which are connected to the outer circumference of the connection portion 2323 and are arranged in plurality around the connection portion 2323, so that there is a gap between the connection portion 2323 and the inner circumference of the second opening 2303. In this way, since the ribs 2324 are arranged at intervals on the outer circumference of the connection portion 2323, a flow channel for the consumables will be formed between adjacent ribs 2324, and the ribs 2324 will separate the connection portion 2323 from the inner circumference of the second opening 2303, ensuring that there is enough space between the connection portion 2323 and the inner circumference of the second opening 2303 for the consumables to flow out, and when the switch member 232 opens the second opening 2303, the consumables can flow out through the flow channel.

[0055] As shown in the figure, in some embodiments, the switch member 232 can be movably passed through the quantitative cavity. Optionally, the movement direction of the switch member 232 is perpendicular to the quantitative cavity. In addition, the driving member and the consumable storage cavity are respectively located on opposite sides of the quantitative cavity. Through the above arrangement, the pumping component liquid pumping effect of the pumping component can be optimized, the component liquid can be pumped stably, and the pumping stability can be improved. In addition, the action of the switch member can be facilitated to facilitate the fluid to enter the pumping component and the fluid to be sent out from the pumping component.

[0056] like Figures 3 to 6 In some embodiments, the pump housing 231 also includes a housing body, a liquid inlet channel 2314 and a liquid outlet channel 2315. The liquid inlet channel 2314 is connected to the first opening 2302, and the liquid outlet channel 2315 is connected to the second opening 2303. The liquid inlet channel 2314 can be used to connect the consumable cavity to facilitate the consumables in the consumable box to flow into the quantitative cavity 2301 through the first opening 2302, and the liquid outlet channel 2315 can provide guidance for the consumables flowing out of the second opening 2303 to discharge the consumables toward a predetermined position.

[0057] Among them, the liquid inlet channel 2314 and the liquid outlet channel 2315 are arranged on the same side of the shell body. It can also be arranged that the peripheral wall of the liquid outlet channel 2315 surrounds the peripheral wall of the liquid inlet channel 2314. By arranging the liquid inlet channel 2314 and the liquid outlet channel 2315 on the same side of the first side wall 2311, it is convenient for the pumping assembly 23 to connect other structures and improve the installation efficiency of the pumping assembly 23. In addition, the nested arrangement of the liquid inlet channel 2314 and the liquid outlet channel 2315 can reduce the space utilization rate of the liquid inlet channel 2314 and the liquid outlet channel 2315. The center line of the liquid outlet channel 2315 is lower than the center line of the liquid outlet channel 2315. Thereby, the consumables in the quantitative cavity 2301 can be conveniently discharged from the liquid outlet channel 2315.

[0058] In some embodiments, the second opening 2303 is disposed near the bottom surface of the quantitative cavity 2301. This facilitates the discharge of the consumables in the quantitative cavity 2301, thereby reducing the long-term retention of the cooking consumables in the quantitative cavity 2301 and optimizing the washing effect.

[0059] like Figure 3 , Figure 5 and Figure 6 In some embodiments of the present application, the pump housing 231 has a first side wall 2311 and a second side wall 2312 opposite to each other, and the first side wall 2311 and the second side wall 2312 are respectively arranged on opposite sides of the quantitative cavity 2301, and the first opening 2302 is arranged on the first side wall 2311, and the second opening 2303 is arranged on the second side wall 2312. Through the relative arrangement of the first opening 2302 and the second opening 2303, the switch member 232 can be used to quickly switch between the first state and the second state, so as to facilitate the switching of the quantitative cavity 2301 between the state of consumables flowing in and the state of consumables flowing out, and realize the rapid pumping assembly to deliver consumables. Especially when the demand for consumables is high, the state of the switch member 232 is quickly switched, so that the consumables can be quickly quantitatively delivered, thereby improving the delivery efficiency and effect of the consumables.

[0060] like Figure 2 and Figure 3 In some embodiments, at least a portion of the switch member 232 is disposed between the first side wall 2311 and the second side wall 2312, and is movable along the arrangement direction of the first side wall 2311 and the second side wall 2312. The switch member 232 can be positioned to switch between the first state and the second state, which not only simplifies the structure of the switch member 232, but also opens the second opening 2303 while closing the first opening 2302, and opens the first opening 2302 while closing the second opening 2303, which improves the stability of the state switching of the switch member 232, avoids the failure of consumables delivery caused by the first opening 2302 being closed and the second opening 2303 not being opened, and effectively improves the stability of consumables delivery.

[0061] like Figure 3 and Figure 6 In some embodiments, the pump housing 231 further includes a third side wall 2313, which is disposed on a side of the second side wall 2312 away from the first side wall 2311, and a positioning cylinder 2316 is disposed on the third side wall 2313, and a part of the switch member 232 is movably disposed in the positioning cylinder 2316 and closes the positioning cylinder 2316. The third side wall 2313 can facilitate the installation of the driving member 233 and the switch member 232, and the positioning cylinder 2316 on the third side wall 2313 can realize the installation and positioning of the switch member 232, thereby improving the stability of the switch member 232 during operation.

[0062] In addition, combined Figure 3 and Figure 7 The switch member 232 also includes a sealing portion 2325, which is constructed into an annular structure and is configured as a flexible membrane structure, wherein one end of the sealing portion 2325 is closed and is suitable for connecting the aforementioned connecting portion 2323, the blocking portion and other structures, and the other end of the sealing portion 2325 is connected to the peripheral wall of the positioning cylinder 2316 to close the positioning cylinder 2316. Through the sealing portion 2325, a stable connection between the driving member 233 and the switch member 232 can be achieved, and the pump housing 231 can be sealed, and the driving member 233 to drive the switch member 232 is convenient.

[0063] Among them, a crimping portion can be set on the positioning cylinder 2316, and the crimping portion cooperates with the positioning cylinder 2316 and cooperates with the positioning cylinder 2316 along the axial or radial direction of the positioning cylinder 2316 to press the other end of the sealing portion 2325 against the positioning cylinder 2316 to achieve sealing of the pump housing 231.

[0064] In addition, the driving member 233 may include a reset member, which may be connected to the switch member 232 and apply force to the switch member 232 to drive the switch member 232 to have an elastic force to switch to the first state.

[0065] Combination Figure 2 and Figure 3 The driving member 233 also includes a positioning part, which is sleeved in the switch member 232 to provide a skeleton support for the switch member 232. The other end of the positioning part cooperates with the driving structure and the reset member. The positioning part can be driven by the driving structure to drive the switch member 232 to the second state, and the reset member can drive the switch member 232 to the first state, so that the switch member 232 can be driven to switch between the first state and the second state through the cooperation of the driving structure and the positioning part. Among them, the other end of the positioning part is provided with a hook, which cooperates with the driving structure so that the driving structure can drive the positioning part.

[0066] In some embodiments, Figure 6A liquid outlet channel 2305 is provided in the pump housing 231, and the liquid outlet channel 2305 is connected to the second opening 2303 and can communicate with the space between the second side wall 2312 and the third side wall 2313. Through the liquid outlet channel 2305, the consumables in the second opening 2303 can be discharged to a predetermined position, thereby improving the efficiency of the pumping assembly 23 in delivering consumables.

[0067] As shown in the figure, in some embodiments, the pump housing 231 further has a first pressure relief channel 2306, which is connected to the quantitative chamber 2301 and is used to balance the air pressure in the quantitative chamber 2301. In other words, the first pressure relief channel 2306 can connect the quantitative chamber 2301 with the space outside the pumping assembly, so that when the air pressure in the quantitative chamber 2301 changes, it can facilitate the air pressure balance inside and outside the quantitative chamber 2301. For example, when the fluid enters the quantitative chamber 2301 through the first opening 2302, the air pressure in the quantitative chamber 2301 increases due to the passage of the fluid, and the fluid is difficult to enter the quantitative chamber 2301. When the air pressure in the quantitative chamber 2301 is balanced, the fluid can smoothly enter the quantitative chamber 2301; when the fluid is discharged from the quantitative chamber 2301 through the second opening 2303, the air pressure in the quantitative chamber 2301 decreases due to the outflow of the fluid, and the fluid is difficult to flow out of the quantitative chamber 2301. When the air pressure in the quantitative chamber 2301 is balanced, the fluid can smoothly discharge the quantitative chamber 2301.

[0068] As shown in the figure, the pumping assembly 23 also includes: a cover 234, which is connected to the pump housing 231 and covers the pumping assembly, a first pressure relief channel 2306 is formed between the cover 234 and the pump housing 231, the first side wall and the third side wall are respectively connected to the cover, a gap is provided between the end face of the second side wall and the cover, and the first pressure relief channel is formed after the cover covers the quantitative cavity. The processing and assembly of the pumping assembly 23 can be facilitated, the processing efficiency of the pumping assembly 23 is improved, and the production cost of the pumping assembly 23 is reduced.

[0069] As shown in the figure, the cover body 234 includes a cover body 2341 and an extension 2342. The cover body 2341 is connected to the pump housing 231 and covers the quantitative cavity. The extension 2342 is connected to the cover body 2341 and extends into the quantitative cavity. The quantitative cavity 2301 can be constructed by the cooperation of the extension 2342 and the pump housing 231, and the leakage of the fluid in the quantitative cavity 2301 can be avoided. In addition, by setting the extension 2342, even if the fluid in the quantitative cavity 2301 enters the position where the extension 2342 is located, the space of this part is relatively small, the fluid that can be accommodated is limited, and the impact on the volume of the fluid in the quantitative cavity 2301 is also relatively small. Thereby improving the accuracy of the pumping assembly 23 in the present application.

[0070] In addition, as shown in the figure, the pump housing 231 also has a second pressure relief channel 2307, and the cover 234 covers the second pressure relief channel 2307. Through the second pressure relief channel 2307, the pressure relief of the quantitative chamber 2301 can be facilitated to avoid the pressure increase or decrease in the quantitative chamber 2301, which causes difficulty in fluid circulation.

[0071] In addition, in combination with the above, the pump housing also has a liquid outlet channel 2305, by connecting the liquid storage channel with the second pressure relief channel, and the second pressure relief channel with the first pressure relief channel, the internal and external air pressure of the quantitative chamber is balanced. In other words, the liquid outlet channel is connected to the outside, and the first pressure relief channel, the second pressure relief channel and the liquid outlet channel are connected in sequence to balance the internal and external air pressure of the quantitative chamber. The quantitative chamber 2301 can be connected to the liquid outlet channel 2305 to improve the stability of the pumping assembly 23.

[0072] In addition, the quantitative chamber is arranged between the first side wall and the second side wall; the second pressure relief channel is arranged between the second side wall and the third side wall. The stability of the pumping assembly can be improved, the service life of the pumping assembly can be extended, and the pumping assembly can be conveniently used to deliver liquid. In addition, the quantitative chamber and the second pressure relief channel are arranged adjacent to each other; the second pressure relief channel is arranged between the quantitative chamber and the driving member.

[0073] Among them, the pump housing has a first pressure relief channel, a second pressure relief channel and a liquid outlet channel. The first pressure relief channel is connected to the quantitative chamber, and the liquid outlet channel is connected to the outside. The first pressure relief channel, the second pressure relief channel and the liquid outlet channel are connected in sequence to balance the internal and external air pressures of the quantitative chamber.

[0076] Optionally, the shell 21 has a consumable storage chamber and a delivery channel, the consumable storage chamber is configured to place consumables, and the delivery channel has a water hole, through which water can be supplied to the delivery channel, so that the consumables in the delivery channel are melted in water and discharged from the delivery channel with water, so as to achieve the delivery of consumables, wherein the shell 21 may have one water hole, or may have multiple water holes, that is, water can enter and exit the shell 21 from the same water hole, or from different water holes. In addition, the pumping assembly 23 is connected to the shell 21 and is configured to pump consumables to the delivery channel. Through the pumping assembly 23, the consumables in the consumable storage chamber can be pumped into the delivery channel, so that the consumables are dissolved in the delivery channel and the delivery of the consumables is completed. The drive member and the consumable storage chamber are respectively located on opposite sides of the quantitative chamber.

[0077] In addition, the pumping assembly 23 may be the pumping assembly 23 in the aforementioned embodiment, the first opening 2302 is connected to the consumable storage chamber, and the second opening 2303 is connected to the delivery channel. The structure of the delivery assembly 20 can be simplified, and only the switch 232 is required to open and close the first opening 2302 and the second opening 2303. In addition, during the pumping process, the limitation of the quantitative chamber 2301 can be utilized. During the cycle of one state switching of the switch 232, only a predetermined amount of consumables can be delivered. When more consumables need to be delivered, it is only necessary to switch the switch 232 for multiple times. Therefore, the pumping assembly 23 of the present application can well deliver the consumables quantitatively.
