Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a water cup used for washing machines and a washing machine. Background Art

[0002] Dishwashers have been widely used in home kitchens. Dishwashers are generally equipped with spray arms for spraying water columns, and a concave return water area is set at the bottom of the box. The top of the return water area is covered with a filter plate. A water pump is used to pump water from the return water area to the spray arm above the filter plate to achieve a circulating spray of washing water. Using an open water pump to draw water for the spray arm can greatly shorten the return water path, improve the return water efficiency, and facilitate the maintenance of the water pump. However, compared with dishwashers using closed water pumps, since dishwashers using open water pumps need to install the water pump in the return water area, affected by the flow characteristics of the fluid, it has higher requirements for the structure of the return water area.

[0003] The authorization announcement number CN215838898U, "A Cleaning Machine" (application number: CN202023352193.7), discloses a water cup structure for installing an open water pump. The overall shape of the water cup is semicircular. Considering that the spray arm needs to be arranged in the center relative to the box body to better cover the tableware cleaning range, the return water area needs to be offset on the bottom wall of the box body, and the slag collection basket located next to the spray arm is also offset on the bottom wall of the box body. During the return water process, the ideal effect is that the return water enters the return water area after filtering the residue through the slag collection basket, and then is further drawn into the spray arm through the water suction port of the open water pump located in the return water area. However, since the offset distance of the slag collection basket relative to the bottom wall of the box body is too large, the return water enters the return water area before it flows to the slag collection basket, the slag collection effect is poor, and there is a problem of residue retention on the filter plate. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a water cup for a cleaning machine that can maximize the use of space to arrange various functional parts so as to improve the slag collection effect, save water and improve water efficiency in view of the current status of the existing technology.

[0005] The second technical problem to be solved by the utility model is to provide a washing machine using the above-mentioned water cup in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve at least one of the above technical problems is:

[0007] A water cup for a cleaning machine has a concave water return area, which is arranged centrally relative to the bottom wall of the cleaning machine. The water return area is a triangular structure with a smooth transition at the corner, including a first straight edge, a second straight edge, and a third straight edge connected end to end, and each straight edge is smoothly connected by an arc segment at the intersection.

[0008] Preferably, the return water area has three corners, and each corner and its adjacent straight side portion respectively enclose a first installation area for installing a water pump, a second installation area for installing a heater, and a third installation area for installing a slag basket. That is, the first corner of the triangular return water area and its adjacent straight side portion enclose a first installation area for installing a water pump, the second corner of the triangular structure and its adjacent straight side portion enclose a second installation area for installing a heater, and the third corner of the triangular structure and its adjacent straight side portion enclose a third installation area for installing a slag basket. The return water area is divided into blocks using the corners of the triangular structure, and the installation requirements of each area are clarified, so that the water pump, slag basket, and heater are installed compactly in the return water area, thereby making full use of the installation space to reduce the overall volume of the return water area, thereby saving water and improving water efficiency.

[0009] Preferably, the first straight edge and the second straight edge are connected at the intersection by a first arc segment, the main body of the water pump is disc-shaped, and the first arc segment cooperates with the outer edge of the disc-shaped main body to form a radial limit. The first arc segment is exactly matched with the disc-shaped main body of the water pump, which not only reduces the assembly gap between the two and saves assembly space, but also the shapes of the first arc segment and the main body of the water pump are mutually matched and constrained, which facilitates the installation of the water pump.

[0010] Preferably, the second straight edge and the third straight edge are connected at the intersection by a second arc segment, the heating element is disc-shaped, and the second arc segment is matched with the outer edge of the disc-shaped heating element. The above structure not only saves assembly space, but also the inner wall of the return water area corresponding to the second arc segment can guide the return water so that it converges to the heating element and then is sucked into the water pump, which is conducive to improving the heating effect.

[0011] Preferably, the first straight edge and the third straight edge are connected at the intersection by a third arc segment, the slag collecting basket is cylindrical, and the third arc segment is adapted to the outer wall of the cylindrical slag collecting basket. The above structure not only saves assembly space, but also the inner wall of the return water area corresponding to the third arc segment can guide the return water to avoid the return water from being retained outside the slag collecting basket, thereby avoiding the accumulation of residue outside the slag collecting basket and improving the slag collecting effect and return water efficiency.

[0012] Preferably, the depths of the second installation area, the first installation area, and the third installation area in the vertical direction increase successively. This structure is beneficial to improving water pumping efficiency, heating effect, and slag collection effect.

[0013] Preferably, the first installation area, the second installation area and the third installation area have a smooth transition at the connection point. This structure is conducive to reducing fluid energy loss.

[0014] A cleaning machine includes a box body and a water pump, a slag collecting basket, and a heating element arranged in the box body, and also includes the above-mentioned water cup, wherein the water cup is installed at the bottom of the box body, and the water pump, the slag collecting basket, and the heating element are installed in the return water area and respectively occupy an angle of the triangular structure.

[0015] Preferably, the water return area is arranged in the center of the bottom wall of the box, the second straight side is arranged parallel to the first side of the bottom wall of the box, the third installation area is arranged corresponding to the central part of the second side of the bottom wall of the box, and the second side is arranged opposite to the first side. The above structure is adopted to maximize the water return efficiency, slag collection efficiency and heating efficiency.

[0016] Preferably, a water inlet is provided at the bottom of the water pump, and a flow channel is provided on the side of the water pump, which spirally extends toward the central part of the triangular structure, and the end of the flow channel extends upward and the upper end forms a water outlet, which is arranged in the center of the bottom of the box. Through such a structure, the water outlet of the water pump, which is offset relative to the return water area and the bottom of the washing chamber, is guided to the center of the bottom of the washing chamber to meet the installation requirements of the bottom spray arm.

[0017] In this embodiment, the water return area is arranged in the center of the bottom of the box, the water pump is offset relative to the center of the bottom wall of the box, and the water outlet of the water pump is arranged corresponding to the central part of the bottom of the box. The "water return area is arranged in the center of the bottom of the box" mentioned above means that the center of the water return area roughly overlaps with the center of the bottom wall of the box body, of course, it may not be completely aligned, for example, it can be: a circular area is formed with the center of the bottom wall of the box body as the center of the circle and the diameter is 5 to 10 mm, and the center of the water return area falls within the circular area; "the water pump is offset relative to the center of the bottom wall of the box body" means that the center of the water pump falls outside the above circular area.

[0018] Preferably, the top of the return water area is covered with a filter plate, which includes a first part and a second part that are spliced ​​together. The edge of the first part constitutes the edge of the filter plate. The first part has an opening corresponding to the shape of the second part at the corresponding third installation area. The second part is embedded in the opening, and the second part has an installation opening for installing a slag collection basket. The contour of the filter plate is formed by the edge of the plastic first part, and the metal second part is embedded in the opening. When the functional parts under the filter plate need to be repaired, the second part can be removed and operated through the opening; because the second part is surrounded by the first part, the assembly gap between the two can be easily made small, thereby reducing the accumulation of residues to improve the cleanliness of the filter plate.

[0019] Preferably, the bottom edge of the opening is provided with an inwardly extending support edge, the second part abuts against the support edge, and the support edge is provided with a slag discharge port extending vertically. With the above structure, the slag can be discharged in time while facilitating the splicing and assembly of the first part and the second part.

[0020] Compared with the prior art, the advantages of the utility model are: the utility model sets the return water area of ​​the water cup as a triangular structure, and can use each corner area of ​​the triangular structure to install a water pump, a slag collecting basket, and a heating element, thereby maximizing the use of the space in the return water area, which not only greatly reduces the volume of the return water area, which is beneficial to saving the amount of washing water each time, but also helps to improve the return water speed and water efficiency; since the water pump no longer occupies the central part of the bottom of the cleaning machine, the slag collecting basket can be closer to the central part of the bottom of the cleaning machine, which is beneficial to improving the slag collecting effect.

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6 As shown, the water cup 2 used for the cleaning machine in this embodiment has a concave water return area 21, and the water return area 21 is arranged centrally relative to the bottom wall of the cleaning machine. The water return area 21 is a triangular structure with smooth corner transitions, including a first straight edge 201, a second straight edge 202, and a third straight edge 203 connected end to end, and each straight edge is smoothly connected by an arc segment at the intersection.

[0029] The above-mentioned water return area 21 has three corners, and each corner and its adjacent straight side portion respectively enclose a first installation area 10 for installing the water pump 3, a second installation area 20 for installing the heating element 5, and a third installation area 30 for installing the slag basket 4. That is, the first corner of the triangular water return area 21 and its adjacent straight side portion enclose the first installation area 10 for installing the water pump 3, the second corner of the triangular structure and its adjacent straight side portion enclose the second installation area 20 for installing the heating element 5, and the third corner of the triangular structure and its adjacent straight side portion enclose the third installation area 30 for installing the slag basket 4. The water return area is divided into blocks by using the corners of the triangular structure, and the installation requirements of each area are clarified, so that the water pump 3, the slag basket 4, and the heating element 5 are compactly installed in the water return area 21, thereby making full use of the installation space to reduce the overall volume of the water return area 21, thereby saving water and improving water efficiency.

[0030] The first straight edge 201 and the second straight edge 202 are connected at the intersection by the first arc segment 01. The main part of the water pump 3 is disc-shaped, and the first arc segment 01 cooperates with the outer edge of the disc-shaped main part to form a radial limit. The first arc segment 01 is exactly adapted to the disc-shaped main part of the water pump 3, which not only reduces the assembly gap between the two and saves assembly space, but also the shapes of the first arc segment 01 and the main part of the water pump 3 are mutually adapted and constrained, which facilitates the installation of the water pump.

[0031] The second straight edge 202 and the third straight edge 203 are connected at the intersection by the second arc segment 02. The heating element 5 is disc-shaped, and the second arc segment 02 is matched with the outer edge of the disc-shaped heating element 5. The above structure not only saves assembly space, but also the inner wall of the return water area 21 corresponding to the second arc segment 02 can guide the return water so that it converges to the heating element 5 and then is sucked into the water pump 3, which is conducive to improving the heating effect.

[0032] The first straight edge 201 and the third straight edge 203 are connected at the intersection by the third arc segment 03, the slag collecting basket 4 is cylindrical, and the third arc segment 03 is adapted to the outer wall surface of the cylindrical slag collecting basket 4. The above structure not only saves assembly space, but also the inner wall of the return water area 21 corresponding to the third arc segment 03 can guide the return water to avoid the return water from being retained outside the slag collecting basket 4, so as to avoid the accumulation of residue outside the slag collecting basket 4, thereby improving the slag collecting effect and the return water efficiency.

[0033] The second installation area 20, the first installation area 10, and the third installation area 30 of this embodiment have increasing depths in the vertical direction. This structure is conducive to improving water pumping efficiency, heating effect, and slag collection effect.

The water pump 3, the slag collecting basket 4, and the heating element 5 are installed in the return water area 21 and each occupies an angle of the triangular structure.

[0035] The water return area 21 is arranged in the center of the bottom wall of the box, the second straight edge 202 is arranged parallel to the first edge 101 of the bottom wall of the box, the third installation area 30 is arranged corresponding to the central part of the second edge 102 of the bottom wall of the box, and the second edge 102 is arranged opposite to the first edge 101. The above structure is adopted to maximize the water return efficiency, slag collection efficiency and heating efficiency.

[0036] The bottom of the water pump 3 is provided with a water inlet 33, and the side of the water pump 3 is provided with a flow channel 34 extending spirally toward the central part of the triangular structure, the end of the flow channel 34 extends upward and the upper end forms a water outlet 31, and the water outlet 31 is arranged in the center of the bottom of the box body 1. Through such a structure, the water outlet 31 of the water pump 3 offset relative to the return water area 21 and the bottom of the washing chamber is guided to the center of the bottom of the washing chamber to meet the installation requirements of the bottom spray arm 6.

[0037] The top of the return water area 21 is covered with a filter plate 7, which includes a first part 71 and a second part 72 that are spliced ​​together. The edge of the first part 71 constitutes the edge of the filter plate. The first part 71 has an opening 712 that matches the shape of the second part 72 at the corresponding third installation area 30. The second part 72 is embedded in the opening 712. The second part 72 has an installation opening 721 for installing the slag collection basket 4. The contour of the filter plate 7 is formed by the edge of the plastic first part 71, and the metal second part 72 is embedded in the opening 712. When the functional parts under the filter plate 7 need to be repaired, the second part 72 can be removed and operated through the opening 712; because the second part 72 is surrounded by the first part 71, the assembly gap between the two can be easily made small, thereby reducing the accumulation of residues to improve the cleanliness of the filter plate.

[0038] The bottom edge of the opening 712 is provided with an inwardly extending support edge 713, on which the second part 72 abuts, and the support edge 713 is provided with a vertically through-going slag discharge port 131. With the above structure, the first part 71 and the second part 72 can be assembled conveniently and the residue can be discharged in time.

[0039] In this embodiment, the water return area 21 of the water cup 2 is configured as a triangular structure, and each corner area of ​​the triangular structure can be used to install the water pump 3, the slag collecting basket 4, and the heating element 5, so that the space of the water return area 21 is utilized to the maximum extent, which not only greatly reduces the volume of the water return area 21, which is beneficial to saving the amount of washing water each time, but also helps to improve the water return speed and water efficiency; because the water pump 3 no longer occupies the central part of the bottom of the cleaning machine, the slag collecting basket 4 can be closer to the central part of the bottom of the cleaning machine, which is beneficial to improve the slag collecting effect.
