Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, specifically relating to a water cup assembly and a dishwasher. Background Technology

[0002] During the draining process, dishwashers often cannot completely drain the water from the cup assembly, leaving water stains inside the cup. These residual water stains can provide a breeding ground for bacteria, affecting the cleanliness of the tableware. In addition, long-term water accumulation can also cause corrosion and damage to the inside of the cup assembly, shortening its lifespan. Furthermore, water stains on the cup assembly negatively impact the user experience. Summary of the Invention

[0003] This application provides a water cup assembly and a dishwasher, aiming to at least partially solve the technical problem that water stains remain inside the cup of the water cup assembly, affecting the cleanliness of tableware and causing corrosion and damage inside the cup of the water cup assembly, so as to improve the service life of the dishwasher and the user experience.

[0004] In a first aspect of this application, a water cup assembly is provided, the water cup assembly comprising: a cup body having a water outlet; a drain component having a drain cavity and an inlet and a drain outlet communicating with the drain cavity, the inlet and the outlet being connected, the inlet being disposed at the top of the drain cavity; and a pump body having an output portion disposed within the drain cavity to guide water from the cup body into the drain cavity from the inlet and out through the drain outlet.

[0005] The water cup assembly provided in this application features a design where the water outlet of the cup body is connected to the water inlet of the drain component, and both the water inlet and outlet of the drain component are connected to the drain chamber. Under the action of the pump's output section, water from the cup body is introduced into the drain component through the water outlet and the water inlet of the drain component, and then discharged into the municipal water supply network through the drain outlet of the drain component. Because the water inlet is located at the top of the drain chamber, the drain chamber is lower than the water outlet of the cup. Even if the water introduced into the drain chamber cannot fill it completely, backflow of water from the drain chamber into the cup body is prevented, thus avoiding water stains remaining inside the cup. This improves the cleanliness of the tableware and prevents internal corrosion and damage to the cup body, thereby extending the dishwasher's lifespan and enhancing the user experience.

[0006] In some implementations, the heights of the water outlet, the water inlet, and the water outlet decrease sequentially, so that the contents of the cup can be discharged through the water outlet by their own weight, which can also avoid water stains remaining in the draining component to a certain extent.

[0007] In some implementations, the drain outlet is connected to the periphery or bottom of the drain cavity.

[0008] In some embodiments, the drainage component includes: a housing with a built-in drainage cavity, the housing having the water inlet and the drain outlet.

[0009] In some embodiments, the drain element further includes a sealing plate that is detachably attached to the bottom of the drain cavity.

[0010] In some implementations, a limiting member is provided at the bottom of the periphery of the housing, and a first connecting member is provided on the periphery of the sealing plate, the first connecting member being snapped onto the limiting member.

[0011] In some embodiments, the pump body includes a support shaft and an impeller, the support shaft being rotatably connected to the drainage chamber, the impeller being rotatably connected to the support shaft, and the impeller being configured as the output portion of the pump body.

[0012] In some embodiments, the pump body further includes a drive unit connected to the housing, and the support shaft is connected to the output shaft of the drive unit.

[0013] In some embodiments, a second connector is provided at the top of the periphery of the housing, and the bottom of the drive member is connected to the second connector.

[0014] In some implementations, the cup assembly further includes a one-way valve connected to the drain outlet of the drain fitting.

[0015] In a second aspect, this application also provides a dishwasher that includes the aforementioned water cup assembly.

[0016] Dishwashers equipped with the aforementioned cup assembly can prevent water stains from remaining inside the cup, thus improving the cleanliness of the tableware and preventing internal corrosion and damage to the cup, thereby extending the dishwasher's lifespan and enhancing the user experience.

[0039] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] Dishwashers are an indispensable appliance in modern home and commercial kitchens, greatly simplifying the dishwashing process. Figure 1 A schematic diagram of the structure of a water cup assembly in the related art is shown. Figure 2 It shows Figure 1 A cross-sectional schematic diagram of AA. Combined with... Figure 1 as well as Figure 2 In related technologies, the water cup assembly includes a cup body 100' and a drain component 200'. The bottom of the cup body 100' is provided with a water outlet 101', and the drain component 200' is provided with a water inlet 201' and a drain outlet 202'. The drain component 200' is provided with a drain chamber 203' that is connected to both the water inlet 201' and the drain outlet 202'. A rotatable impeller 300' is provided in the drain chamber 203'. Water in the body 100' is introduced into the drain chamber 201' of the drain component 200' through the water outlet 101' and the water inlet 201' of the drain component 200'. Driven by the rotating impeller 300', the water introduced into the drain chamber 203' is discharged into the municipal pipe network through the drain outlet 202' of the drain component 200'.

[0041] In related technologies, the drain chamber is positioned no lower than the water outlet of the cup. Water introduced into the drain chamber can only be completely drained when the chamber is fully filled. However, because the water inlet is located in the middle of the side of the drain component, during the final stage of the dishwasher's draining process, the water introduced into the drain chamber cannot completely fill it. This results in the water not being completely drained, often leading to incomplete drainage and even backflow into the cup. This leaves water stains inside the cup assembly, which can provide a breeding ground for bacteria, affecting the cleanliness of the tableware. Furthermore, long-term water accumulation can cause corrosion and damage to the inside of the cup assembly, shortening its lifespan. The water stains also negatively impact the user experience, indicating room for improvement.

[0042] Based on the above-mentioned technical problems, this application provides a water cup assembly and a dishwasher, aiming to at least partially solve the technical problems of water stains remaining inside the cup body of the water cup assembly, which affects the cleanliness of tableware and causes corrosion and damage inside the cup body of the water cup assembly, so as to improve the service life of the dishwasher and the user experience.

[0043] In a first aspect of this application, a water cup assembly is provided. Figure 3 A schematic diagram of the structure of a water cup assembly according to one or more embodiments of this application is shown. Figure 4 It shows Figure 3 BB cross-sectional diagram, Figure 5 It shows Figure 3 A schematic diagram of the water cup assembly without the cup body. Figure 6 It shows Figure 5 A cross-sectional schematic diagram. Combined with... Figures 3-6 The water cup assembly includes a cup body 100, a drain component 200, and a pump body 300. The cup body 100 is provided with a water outlet 101. The drain component 200 is provided with a drain chamber 204 and a water inlet 201 and a drain outlet 202 connected to the drain chamber 204. The water inlet 201 and the water outlet 101 are connected. The water inlet 201 is located at the top of the drain chamber 204. The output part of the pump body 300 is located in the drain chamber 204 to guide the water in the cup body 100 to flow from the water inlet 201 into the drain chamber 204 and be discharged through the drain outlet 202.

[0044] The water cup assembly provided in this application has a water outlet 101 of the cup body 100 and a water inlet 201 of the drain component 200 connected. The water inlet 201 and the drain outlet 202 of the drain component 200 are both connected to the drain chamber 204. Under the action of the output part of the pump body 300, the water in the cup body 100 is introduced into the drain component 200 through the water outlet 101 and the water inlet 201 of the drain component 200, and discharged into the municipal pipe network through the drain outlet 202 of the drain component 200. Because the water inlet 201 is located at the top of the drain chamber 204, the drain chamber 204 is lower than the water outlet 101 of the cup 100. Even at the end of the dishwasher's draining process, the water introduced into the drain chamber 204 cannot fill the drain chamber 204, which can prevent the water in the drain chamber 204 from flowing back into the cup body 100. This avoids the phenomenon of water stains remaining in the cup body 100, thereby improving the cleanliness of the tableware and preventing corrosion and damage inside the cup body 100, thus improving the service life of the dishwasher and the user experience.

[0045] In addition, combined Figure 6 In this application, the heights of the water outlet 101, water inlet 201, and drain outlet 202 decrease sequentially, so that the water in the cup body 100 is completely drained into the drain component 200 by the weight of the water. This can, to a certain extent, prevent water stains from remaining in the cup body 100, thereby improving the cleanliness of the tableware and preventing corrosion and damage inside the cup body 100, thus improving the service life of the dishwasher and the user experience.

[0046] Combination Figure 3 as well as Figure 4 The cup body 100 of this application has a receiving cavity 102, the top of which is open to store residual water formed after the cleaning water sprayed by the dishwasher's spray assembly cleans the dishes. A circulation port (not shown) is also provided on the side wall of the cup body 100 to filter the residual water in the cup body 100 before sending it to the spray assembly to clean the dishes again. This cycle is repeated to complete the cleaning of the dishes in the dishwasher. After the dishes are cleaned, the drain component 200 operates, introducing water from the main body into the drain component 200 through the outlet 101 and the inlet 201, and then discharging it into the municipal sewer network through the drain outlet 202.

[0047] Combination Figure 4In one embodiment, the outlet 101 can be located on the side of the bottom of the cup body 100, and the drain component 200 is located adjacent to the cup body 100. The inlet 201 of the drain component 200 and the outlet 101 of the cup body 100 are connected by a water supply pipe 400 to reduce the space occupied by the pipe. In another embodiment, the outlet 101 can also be located in the middle of the bottom of the cup body 100. In one embodiment, the supply pipe can be inclined, that is, the height of the end of the supply pipe connected to the outlet 101 is higher than the height of the end of the supply pipe connected to the inlet 201, to avoid water in the cup body 100 remaining in the supply pipe. In another embodiment, the drain pipe 600 can also be arranged horizontally, without limitation.

[0048] Figure 7 It shows Figure 5 A schematic diagram of the exploded structure. Combined with... Figures 4-7 The drainage component 200 of this application includes a housing 203, which is provided with an inlet 201 and a drain outlet 202. The output part of the pump body 300 is disposed inside the housing 203 to guide the water in the cup body 100 to flow into the housing 203 from the inlet 201 and out to the municipal pipe network through the drain outlet 202.

[0049] Combination Figure 4 as well as Figure 6 The housing 203 of this application is provided with a drainage chamber 204. A water inlet 201 is provided at the top of the housing 203, and a drain outlet 202 is provided on the periphery of the housing 203. Both the water inlet 201 and the drain outlet 202 communicate with the drainage chamber 204. The output part of the pump body 300 is rotatably disposed within the drainage chamber 204. Residual water collected in the receiving cavity 102 within the cup body 100 is introduced into the drainage chamber 204 through the water inlet 201, and discharged to the municipal water supply through the drain outlet 202 under the drive of the output part of the pump body 300.

[0050] Combination Figure 4 as well as Figure 6 In this application, since the water outlet 101 is located at the bottom of the cup body 100 and the water inlet 201 is located at the top of the shell 203, a water flow path from top to bottom is formed so that water is guided from the cup body 100 to the drain chamber 204 of the shell 203 under its own weight, thus avoiding the cleaning and corrosion problems caused by water remaining in the cup body 100.

[0051] Combination Figure 4 , Figure 6 as well as Figure 7The pump body 300 of this application includes a support shaft 301 and an impeller 302. The support shaft 301 is rotatably connected to the drainage chamber 204, and the impeller 302 is rotatably connected to the support shaft 301. The impeller 302 is configured as the output part of the pump body 300. Driven by the rotating impeller 302, the water in the drainage chamber 204 is led out from the drain outlet 202 to the municipal pipe network.

[0052] Figure 8 It shows Figure 7 A schematic diagram of the supporting shaft in the middle. Figure 9 A cross-sectional structural diagram of the impeller assembled on the support shaft is shown. (Combined with...) Figures 6-9 The support shaft 301 is arranged vertically, and a first partition 303 is provided on the support shaft 301. The top of the impeller 302 is placed under the first partition 303, and the bottom of the impeller 302 rests against the sealing plate 205. Through the support and restriction of the first partition 303 and the sealing plate 205, the impeller 302 can rotate stably in the drainage chamber 204.

[0053] Combination Figure 8 In one embodiment, the cross-section of the support shaft 301 used to connect the impeller 302 is square, and the impeller 302 is fitted onto this part so that the impeller 302 rotates synchronously with the support shaft 301. In another embodiment, the impeller 302 can also be connected to the support shaft 301 by means of a key connection or other methods, and there is no limitation on this.

[0054] Combination Figure 6 , Figure 8 as well as Figure 9 A second partition 304 is also provided on the support shaft 301. The second partition 304 is located on the top lower side of the drainage cavity 204 of the housing 203 to restrict the axial movement of the support shaft 301.

[0055] Combination Figure 6 as well as Figure 7 To facilitate the assembly of the support shaft 301 and impeller 302 within the drainage chamber 204, a detachable sealing plate 205 is provided at the bottom of the drainage chamber 204 in this application. When assembling the support shaft 301 and impeller 302, the sealing plate 205 can be removed from the housing 203 to assemble the support shaft 301 and impeller 302; after the support shaft 301 and impeller 302 are assembled, the sealing plate 205 is then reattached to the housing 203 to seal the bottom of the drainage chamber 204.

[0056] Figure 10 It shows Figure 7 A structural diagram of the drainage components in the diagram. Figure 11 It shows Figure 7 A schematic diagram of the sealing plate structure. (Combined with...) Figure 7 , Figure 10 as well as Figure 11In one embodiment, a limiting member 206 is provided at the bottom periphery of the housing 203, and a first connecting member 207 is provided on the periphery of the sealing plate 205. The first connecting member 207 is snapped onto the limiting member 206 to achieve a detachable connection between the sealing plate 205 and the housing 203. Multiple first protrusions are spaced apart on the periphery of the housing 203, and the first protrusions are integrally formed on the housing 203. Each first protrusion can be configured as a first connecting member 207. Multiple buckles are spaced apart on the periphery of the sealing plate 205, and each buckle corresponds to one of the first protrusions. Each buckle can be configured as a first connecting member 207 and snaps onto the corresponding first protrusion. When assembling the sealing plate 205 onto the housing 203, align the snaps with the gaps between adjacent first protrusions, then rotate the sealing plate 205. The snaps of the sealing plate 205 rotate and engage with the corresponding snaps, thereby connecting the sealing plate 205 to the housing 203. To remove the sealing plate 205 from the housing 203, simply rotate the sealing plate 205 to unscrew the snaps from the corresponding snaps; this process is convenient and quick. In another embodiment, the limiting member 206 and the first connecting member 207 can also be connected by screws; this is not a limitation.

[0057] Combination Figure 4 , Figure 9 as well as Figure 10 The bottom of the drainage cavity 204 of this application is provided with a stop 2041, and the sealing plate 205 is provided with a protrusion 2051. The protrusion 2051 is sealed and embedded to the stop 2041 at the bottom of the drainage cavity 204. A first sealing member 208 is provided between the stop 2041 and the protrusion 2051 to ensure the sealing between the sealing plate 205 and the housing 203.

[0058] Combination Figure 9 A first mounting hole 2052 is provided at the center of the top of the sealing plate 205. The bottom end of the support shaft 301 is rotatably connected to the first mounting hole 2052. The first mounting hole 2052 is a blind hole. A first bearing 209 can be provided between the bottom end of the support shaft 301 and the first mounting hole 2052 to improve the smoothness of the rotation of the support shaft 301 on the sealing plate 205.

[0059] Combination Figure 5 as well as Figure 6 In one embodiment, the pump body 300 of this application further includes a drive component 305, which can be a motor connected to the outside of the housing 203. A support shaft 301 is connected to the output shaft of the drive component 305. The drive component 305 drives the support shaft 301 to rotate, thereby causing the impeller 302 to rotate synchronously with the support shaft 301, so as to draw water from the drain chamber 204 out of the drain outlet 202 to the municipal pipe network. In another embodiment, the drive component 305 can also be placed inside the housing 203, but a sealed cavity needs to be configured to house the drive component 305.

[0060] Figure 11 It shows Figure 9 Another structural diagram from the perspective of Figure 12 It shows Figure 6 A schematic diagram of the driving component. (Combined with...) Figure 11 as well as Figure 12 A second connector 210 is provided on the top periphery of the housing 203, and the bottom of the drive member 305 is connected to the second connector 210. In one embodiment, a plurality of second protrusions are spaced apart on the top periphery of the housing 203, and the second protrusions are integrally formed on the housing 203. Each second protrusion can be configured as a second connector 210, and the second protrusions can be connected to the bottom of the drive member 305 by screws to avoid the phenomenon that the connection between the drive member 305 and the housing 203 is not firm due to vibration generated during the operation of the drive member 305. In another embodiment, an annular structure can also be provided on the top periphery of the housing 203, and the annular structure can be configured as a second connector 210. The annular structure can also be connected to the bottom of the drive member 305 by screws.

[0061] Combination Figure 4 as well as Figure 11 A second mounting hole 211 is provided at the top of the housing 203 for the support shaft 301 to pass through. The top end of the support shaft 301 rotatably passes through the second mounting hole 211 to connect with the output shaft of the drive member 305. Similarly, a second bearing 213 can be provided between the support shaft 301 and the second mounting hole 211 to improve the smoothness of the rotation of the support shaft 301 on the housing 203.

[0062] Combination Figure 4 Since the support shaft 301 needs to pass through the housing 203 to connect with the drive component 305, the second mounting hole 211 is a through hole. In order to improve the sealing performance of the drainage chamber 204 of the housing 203, a second seal 212 can be provided between the mounting shaft and the top of the housing 203. The second seal 212 is located below the second bearing 213 to prevent water from entering the second bearing 213 and improve the reliability of the second bearing 213.

[0063] Referring to Figures 1-4, the water cup assembly of this application also includes a one-way valve 500, which is connected to the drain outlet 202 of the drain component 200 via the drain pipe 600. During the drainage phase, the one-way valve 500 opens to discharge the water in the drain chamber 204 to the municipal water supply network. After drainage is completed, the one-way valve 500 closes to prevent the discharged water from flowing back into the drain component 200 and the cup body 100, thus avoiding incomplete drainage and odors, thereby improving the user experience.

[0064] In a second aspect, this application also provides a dishwasher that includes the aforementioned water cup assembly.

[0065] The dishwasher equipped with the aforementioned cup assembly can use the weight of the water to drain all the water in the cup body 100 into the drain component 200, thereby avoiding water stains remaining in the cup body 100 to a certain extent, improving the cleanliness of the tableware, and preventing corrosion and damage inside the cup body 100, thus extending the service life of the dishwasher and improving the user experience.
