Description

Technical Field

[0001] This application belongs to the technical field of dishwashers, and particularly refers to a water supply system for a dishwasher. Background Art

[0002] With the increasing development of technology and the improvement of living standards, especially the rapid development of home appliance technology, there are specialized dishwashing devices for tableware cleaning. A multifunctional dishwasher generally has functions such as spraying, drying, and sterilization. Users only need to put tableware such as bowls and chopsticks into the dishwasher, and the dishwasher can automatically complete a series of cleaning tasks according to the user's settings. It is convenient to use and fully automated, effectively reducing the user's operation. Therefore, dishwashers are becoming more and more popular among thousands of households and are deeply loved by users.

[0003] Currently, dishwashers on the market generally have a water filling connector connected to a water source. Through this water filling connector, it is connected to the tap water source to add water to the dishwasher, so that the dishwasher can operate normally. When there is no tap water source, the tap water source pressure is insufficient, or the layout of the external tap water pipe is difficult to connect, etc., it is impossible or difficult to connect to the tap water source, resulting in the dishwasher being unable to be used normally, thereby limiting the use environment of the dishwasher, with low applicability and unable to meet the needs of the use environment of the majority of users. Regarding the water supply problem of dishwashers, manufacturers of existing technologies have developed a solution to add an external water supply device to the dishwasher. A common solution is to externally place a water supply device and connect it to the water filling connector of the dishwasher through a pipeline, so that when the dishwasher cannot be directly connected to the tap water source, the water supply device can add water to the dishwasher, so that the dishwasher can be used normally.

[0004] The existing external water supply device of the prior art is generally independently set, with a large volume, occupying a large area and a lot of space, which is not conducive to the use environment of users with narrow spaces. Moreover, in order to facilitate water filling of the water supply device, a water filling structure is generally set on the upper part of the water supply device, such as opening a water filling port or setting a water filling connector and other structures, resulting in a more complex structure of the entire water supply device, cumbersome operation, and a relatively high cost for separate mold manufacturing.

[0005] Therefore, for the solution of setting a water supply system outside the dishwasher, it is still a research problem that needs to be improved by dishwasher manufacturers at present. Summary of the Invention

[0006] The purpose of the embodiments of this application is to provide a water supply system for a dishwasher, which improves the external water supply device connected to the dishwasher, has a simple structure, low manufacturing cost, and can be better combined with the dishwasher for use, effectively saving the occupied space and improving the applicability of the dishwasher.

[0007] To achieve the above object, the technical solution adopted in this application is as follows: A water supply system for a dishwasher is provided, which includes a water storage container for connecting with the dishwasher. The water storage container is provided with an upper cover plate. The upper cover plate is provided with a water delivery pipe and a surrounding edge for fixing the dishwasher. The water delivery pipe is respectively connected to the inside of the dishwasher and the water storage container. An adding water port is provided on the outer periphery of the surrounding edge. The upper cover plate is further provided with an adding water tray and a guiding mechanism for displacing the adding water tray on the adding water port to extend or be received into the water storage container.

[0008] The beneficial effects of the water supply system for the dishwasher provided in this application are as follows: Compared with the prior art, an external water storage container is provided and connected to the dishwasher. The water storage container is provided with an upper cover plate. The upper cover plate is provided with a surrounding edge and a water delivery pipe. The water delivery pipe is respectively connected to the inside of the dishwasher and the water storage container. The surrounding edge encloses the upper surface of the upper cover plate from the outside to fix the dishwasher installed on the water storage container, so that the entire water storage container forms a support base and is spliced at the bottom of the dishwasher. Let the water storage container be used as a base to form an up-and-down splicing connection structure with the dishwasher, effectively saving the occupied space and reducing the space area occupied in the user's usage environment. Moreover, the connection operation is more convenient. The user can directly place the dishwasher on the water storage container to complete the installation operation, effectively improving the installation efficiency.

[0009] Aiming at the problem that the water storage container is used as a base to form an up-and-down splicing connection structure with the dishwasher, and no water adding structure can be set at the top of the water storage container. The water storage container in this application is provided with an adding water port on the outer periphery of the surrounding edge of the upper cover plate, so that the water adding structure is arranged on the side of the water storage container, and an adding water tray matching with the adding water port is set. For the opening and closing structure of the adding water tray, a guiding mechanism for displacing the adding water tray on the adding water port to extend or be received into the water storage container is arranged on the upper cover plate, so that the adding water tray can extend or be received into the water storage container like opening a drawer. Due to the adoption of this drawer-type adding water tray, the water adding method of the water storage container is more diverse, including but not limited to the traditional way of connecting with a tap water faucet, or the way of directly pouring ordinary barreled water into the adding water tray. The water storage container can be quickly filled with water, thus effectively expanding the water adding method and effectively improving the applicability of the dishwasher to meet the usage needs of a wide range of users.

[0010] Improve the guiding mechanism of the water storage container. The guiding mechanism includes guide rails arranged on both sides of the adding water tray and guide shafts arranged on both sides of the adding water port of the upper cover plate. The guide shafts are mutually embedded with the guide rails to displace the adding water tray on the adding water port, thus forming an opening and closing structure similar to a drawer. The structure is simple, and the mold manufacturing cost is low. The user can operate the adding water tray to slide out from the adding water port, or easily push the adding water tray to slide into the adding water port and be received into the water storage container. The operation is simple and convenient to use.

[0011] Optionally, a guiding groove is provided on the peripheral edge, which is connected to the water filling port and extends obliquely towards the bottom of the water storage container. The water filling tray has an upper opening, and a water filling cover for covering the water filling port is provided around the outer periphery of the upper opening, a water outlet opposite to the position of the water filling cover, and side wall portions provided on both sides of the water filling tray and connected to the water filling cover. The end portions of the side wall portions on both sides of the water outlet are provided with abutting portions that abut against the inner bottom surface of the water storage container. On the one hand, under the restriction of the guiding groove, the water filling tray is inclined, so that after the water filling tray slides out of the water filling port, it is convenient for the user to add water to the water storage container. The water filling tray can be used as a guiding tray, and the user can add water to the water filling tray from the upper opening of the water filling tray. The water flow on the water filling tray is obliquely led into the water storage container from the water outlet, so as to adapt to the access mode of a tap water faucet or directly pour barreled water, and add water to the water storage container, effectively improving the applicability of the water storage container. On the other hand, the abutting portions are provided on the side wall portions of the water filling tray, so that the water filling tray can slide into the water storage container along the guiding groove and extend towards the bottom of the water storage container, so that the abutting portions abut against the inner bottom surface of the water storage container, so that the water filling tray can be inclined and stored in the water storage container, effectively reducing the occupied space and improving the utilization rate of the internal space of the water storage container.

[0012] Optionally, the outer periphery of the surrounding edge is inclined, and abutting tops are further provided at the ends of the side wall portion of the water adding tray on both sides of the water outlet; a limiting portion that abuts against the abutting top is provided on the inner wall of the guiding groove above the water adding port, and a supporting platform for supporting the water adding tray is provided on the inner wall of the guiding groove below the water adding port; the guide rail on the water adding tray is arranged outside the side wall portion, and positioning grooves for the guide shafts to be embedded in and for limiting the extending position of the water adding tray are provided at the ends of the guide rail on both sides of the water outlet. Since the water storage container is used as an up-and-down connection structure for splicing with the dishwasher, the bottom peripheral structure of the dishwasher is relatively close to the water adding port of the water storage container. When the water adding tray is pulled out from the water adding port, it is easily interfered by the bottom peripheral structure of the dishwasher, hindering the water adding operation to the water adding tray. For this reason, the outer periphery of the surrounding edge of the upper cover plate of the water storage container is inclined, so that a stepped structure with an upper and lower dislocation is formed between the upper part and the lower part of the water adding port, and positioning grooves for engaging with the guide shafts on both sides of the water adding port are arranged on the guide rail of the water adding tray. After the water adding tray slides out of the water adding port, by the engagement of the positioning groove and the guide shaft, not only the extending position of the water adding tray is limited, effectively preventing the water adding tray from coming off, but also the water adding tray can rotate with the guide shaft as the rotation axis, thereby changing the extending angle of the water adding tray. Moreover, the limiting portion provided on the inner wall of the guiding groove above the water adding port abuts against the abutting top on the side wall portion of the water adding tray, thus limiting the rotation direction of the water adding tray, so that after the water adding tray extends out of the water adding port, it can only rotate downward with the guide shaft as the axis, thereby increasing the distance from the bottom peripheral structure of the dishwasher. The settable rotatable angle after the water adding tray extends out, on the one hand, can effectively reduce the interference of the bottom peripheral structure of the dishwasher on the water adding tray, enabling the user to smoothly perform the water adding operation on the water adding tray; on the other hand, the water adding tray after the rotation angle adjusts the inclination angle to a large obtuse angle, which is beneficial to slowing down the water inlet flow rate, enabling the user to better control the water addition amount. In addition, the limiting portion provided on the inner wall of the guiding groove above the water adding port and the supporting platform on the inner wall of the guiding groove below the water adding port can respectively abut and fix the abutting top of the water adding tray and the bottom of the water adding tray, thereby forming a supporting structure for fixing the water adding tray after it extends out of the water adding port, effectively improving the fixing effect, so that the user can perform the water adding operation on the water storage container.

[0013] Optionally, a guiding inclined surface matching the contour of the limiting portion is provided on the abutting top of the water adding tray; sockets for the guiding shafts to slide into the guide rails are provided at the two ends of the guide rails on both sides of the water outlet, and a check rib for preventing the guiding shafts from disengaging from the sockets is provided on the sockets of the guide rails. On the one hand, the guiding inclined surface on the abutting top is in abutting cooperation with the inner wall of the guiding groove, so that when the water adding tray is stored, it can rotate along the guiding groove by an angle, and thus return to the inclined state of sliding into the interior of the water storage container from the guiding groove, so that the water adding tray can be close to the inner side wall of the water storage container after being stored, effectively reducing the occupied space inside the water storage container. On the other hand, when the water adding tray is installed on the water adding port, it can be directly inserted into the guide rail through the socket, and the check rib can effectively prevent the guiding shaft from disengaging, so as to quickly install the water adding tray on the water storage container, effectively improving the installation efficiency.

[0014] The structure of the water adding tray is improved. A buckle edge is provided on the water adding cover of the water adding tray, and a buckle groove for buckling with the buckle edge is provided on the support platform; the outer surface of the water adding cover matches the outer peripheral surface contour of the surrounding edge, and a handle groove for a user to insert a finger is further provided on the water adding cover. When the water adding tray is stored in the water storage container, the buckle edge provided on the water adding cover is in buckling cooperation with the buckle groove on the support platform, so that the water adding cover can be hung on the water adding port, thereby fixing the storage state of the water adding tray. The outer surface of the water adding cover matches the outer peripheral surface contour of the surrounding edge, so that the outer surface of the water adding cover can completely cover the water adding port, making the outer peripheral surface of the surrounding edge of the upper cover plate flat and beautiful. Among them, the handle groove on the water adding cover facilitates the user to open and close the water adding tray.

[0015] Optionally, a plurality of anti-splash bumps for preventing water splashing are further provided on the water adding tray, and the plurality of anti-splash bumps are staggered and distributed on the inner bottom surface of the water adding tray. The shape of the anti-splash bumps can preferably be a cylindrical or inverted trapezoidal bump, or can preferably be a rectangular or semi-circular rib, which can effectively prevent the added water flow from splashing on the water adding tray, keep the use environment hygienic, and avoid affecting the calculation of the water adding amount.

[0016] Improve the structure of the water supply system. A water level detection device for detecting the water addition amount of the water storage container is further provided on the upper cover plate. The water level detection device includes a float and a guide post, and the guide post extends towards the bottom of the water storage container; the float is sleeved on the guide post and can move up and down relative to the guide post with the change of the water level to change the distance from the dishwasher located on the upper cover plate; an induction member is provided on the float, and an induction trigger device for making induction cooperation with the induction member of the float is provided at the bottom of the dishwasher. Combining the combined application mode of the water storage container and the dishwasher, a water level detection device is arranged on the upper cover plate of the water storage container. By using the fact that the upper cover plate is located at the top of the entire water storage container and the upper surface of the upper cover plate contacts the bottom of the dishwasher, a float and a guide post are arranged on the upper cover plate, the guide post extends into the water storage container, the float is sleeved on the guide post, and moves up and down with the change of the water level in the water storage container, so as to change the distance between the float and the bottom of the dishwasher, and make the induction member arranged on the float cooperate with the induction trigger device arranged at the bottom of the dishwasher in position. When the float moves up and approaches the bottom of the dishwasher, it will produce a triggering effect with the induction trigger device at the bottom of the dishwasher, thereby sending out an alarm signal. The form of the alarm signal can be the display on the control screen of the dishwasher, buzzer alarm or the combination of the two, etc., effectively reminding the user to stop adding water to the water storage container. Therefore, there is no need to set electrical components on the water storage container to avoid the problem of easy water-related damage, keep the structure of the water storage container simple and convenient to use, and effectively reduce the manufacturing cost.

[0017] Improve the structure of the upper cover plate of the water storage container. A limiting step matching the shape of the bottom of the dishwasher is provided inside the peripheral edge of the upper cover plate; a diversion arc surface connected to the top end of the peripheral edge is provided on the limiting step, and an inner chamfer is formed at the connection between the diversion arc surface and the top end of the peripheral edge. For the up-and-down connection structure where the water storage container is used as a base and spliced with the dishwasher, it is difficult to ensure the central coaxial alignment of the dishwasher and the water storage container. The weight of the dishwasher is difficult to be evenly distributed on the water storage container, and the dishwasher is prone to tipping over, resulting in the dishwasher falling off the water storage container and being damaged. Therefore, on the upper cover plate of the water storage container, in addition to providing a peripheral edge to surround the bottom structure of the dishwasher, a limiting step is also provided inside the peripheral edge. By using the limiting step to fit with the bottom structure of the dishwasher, the installation position of the dishwasher can be effectively positioned. After the dishwasher is installed on the upper cover plate, the central coaxial alignment of the dishwasher and the water storage container can be achieved, so that the weight of the dishwasher can be evenly distributed on the water storage container, improving the supporting effect of the water storage container on the dishwasher, ensuring the structural stability of installing the dishwasher on the top of the water storage container, effectively preventing damage caused by uneven force leading to the dishwasher being easily tipped over and falling off, and ensuring the use safety. Among them, the diversion arc surface provided on the limiting step can effectively collect the overflow water on the dishwasher, avoiding affecting the hygiene of the use environment. Moreover, the inner chamfer formed at the connection between the diversion arc surface and the top end of the peripheral edge can further limit the installation position of the dishwasher, effectively strengthening the positioning effect and playing a role in fixing the dishwasher.

[0018] Optionally, a connection part for connecting with the water delivery pipe is provided at the bottom of the dishwasher. A positioning notch matching the position of the connection part of the dishwasher is also provided on the peripheral edge of the water storage container. An outlet hole through which the water delivery pipe passes through is provided on the upper cover plate at the positioning notch. On the one hand, by aligning the positioning notch with the connection part of the dishwasher, one end of the water delivery pipe is connected to the connection part of the dishwasher, and the other end passes through the outlet hole and extends into the interior of the water storage container, thus realizing the connection of the water supply pipeline; at the same time, the positioning notch can be used as a positioning reference between the dishwasher and the water storage container in the water supply system, effectively limiting the installation position and orientation of the dishwasher installed on the water storage container, so that other components between the dishwasher and the water storage container can be automatically aligned, such as the alignment between the water level detection device of the water storage container and the induction trigger device of the dishwasher, effectively improving the installation positioning between the dishwasher and the water storage container, making the installation operation convenient and enabling automatic alignment. On the other hand, the positioning notch can be used as a drain port, allowing the water flowing into the upper cover plate to drain from the positioning notch, so as to keep the splicing part between the dishwasher and the water storage container hygienic, and at the same time avoid the accumulation of water affecting the induction trigger between the water level detection device and the induction trigger device.

[0043] Please refer to Figure 1 and Figure 2 to illustrate the water supply system of the dishwasher provided by the embodiments of this application. The water supply system includes a water storage container 200 for connecting to the dishwasher 100. The water storage container 200 is provided with an upper cover plate 1. The upper cover plate 1 is provided with a surrounding edge 11 for fixing the dishwasher 100 and a water delivery pipe 12 for waterway connection. The water delivery pipe 12 is respectively connected to the inside of the dishwasher 100 and the water storage container 200. An adding water port 2 is provided on the outer periphery of the surrounding edge 11. The upper cover plate 1 is further provided with an adding water tray 3 and a guiding mechanism for enabling the adding water tray 3 to displace on the adding water port 2 to extend out or be received in the water storage container 200.

[0044] Compared with the prior art, the water supply system of the dishwasher provided by this application is provided with an external water storage container 200 connected to the dishwasher 100. The water storage container 200 is provided with an upper cover plate 1. The upper cover plate 1 is provided with a surrounding edge 11 and a water delivery pipe 12. The water delivery pipe 12 is respectively connected to the inside of the dishwasher 100 and the water storage container 200. The surrounding edge 11 surrounds the upper surface of the upper cover plate 1 from the outside to fix the dishwasher 100 installed on the water storage container 200, so that the entire water storage container 200 forms a support base and is spliced at the bottom of the dishwasher 100. Making the water storage container 200 serve as a base for upper and lower splicing connection with the dishwasher 100 effectively saves the occupied space and reduces the space area occupied in the user's usage environment. Moreover, the connection operation is more convenient. The user can directly place the dishwasher 100 on the water storage container 200 to complete the installation operation, effectively improving the installation efficiency and providing a good user experience.

[0045] Regarding the connection structure where the water storage container 200 is spliced vertically with the dishwasher 100 as the base, and the problem that a water filling structure cannot be set at the top of the water storage container 200. In the water storage container 200 of the present application, a water filling port 2 is provided on the outer periphery of the peripheral edge 11 of the upper cover plate 1, so that the water filling structure is set on the side of the water storage container, and a water filling tray 3 is provided to cooperate with the water filling port 2. Regarding the opening and closing structure of the water filling tray 3, a guiding mechanism is provided on the upper cover plate 1 to enable the water filling tray 3 to displace on the water filling port 2 to extend out or be received into the water storage container 200, so that the water filling tray 3 can extend out or be received into the water storage container 200 like opening a drawer. Due to the adoption of this drawer-type water filling tray 3, the water filling method of the water storage container 200 is more diverse, including but not limited to the traditional connection method of a tap water faucet or the method of directly pouring ordinary barreled water into the water filling tray 3, and the water storage container 200 can be quickly filled with water, thereby effectively expanding the water filling method and effectively improving the applicable performance of the dishwasher 100 to meet the usage requirements of a wide range of users.

[0046] In another embodiment of the present application, the guiding mechanism of the water storage container 200 is optimized. Please refer to Figure 3 and Figure 4 , the guiding mechanism includes guide rails 30 provided on both sides of the water filling tray 3 and guide shafts 21 provided on both sides of the water filling port 2 of the upper cover plate 1. The guide shafts 21 are mutually embedded with the guide rails 30 to enable the water filling tray 3 to displace on the water filling port 2, thereby forming a drawer-like opening and closing structure. The structure is simple, and the mold manufacturing cost is low, allowing the user to operate the water filling tray 3 to slide out from the water filling port or easily push the water filling tray 3 to slide into the water filling port and be received into the water storage container 200. The operation is simple and convenient to use.

[0047] In another embodiment of the present application, please refer to Figure 5 and Figure 6 , a guiding groove 13 is provided on the peripheral edge 11, which is connected to the water filling port 2 and extends obliquely towards the bottom of the water storage container 200. Under the limitation of the guiding groove 13, the water filling tray 3 is inclined, so that after the water filling tray 3 slides out of the water filling port, it is convenient for the user to fill the water storage container 200 with water. The water filling tray 3 can be used as a guiding tray to obliquely guide the incoming water towards the inside of the water storage container 200, so as to adapt to the connection method of a tap water faucet or the method of directly pouring barreled water, and fill the water storage container 200 with water, effectively improving the applicable performance of the water storage container 200.

[0048] Among them, please refer to Figure 4 , Figure 6 and Figure 7, the water adding tray 3 is provided with an upper opening 31, and a water adding cover 32 for covering the water adding port 2 is arranged around the outer periphery of the upper opening 31, a water outlet 33 opposite to the position of the water adding cover 32, and side wall portions 34 arranged on both sides of the water adding tray 3 and connected to the water adding cover 32. An abutting portion 341 for abutting against the inner bottom surface of the water storage container 200 is arranged at the end portions of the side wall portions 34 on both sides of the water outlet 33. It allows users to add water to the water adding tray 3 from the upper opening 31 of the water adding tray 3, and the water flow on the water adding tray 3 is inclined and led into the water storage container 200 from the water outlet 33; moreover, an abutting portion 341 is arranged on the side wall portion 34 of the water adding tray 3, so that the water adding tray 3 can slide into the water storage container 200 along the guiding groove 13 and extend towards the bottom of the water storage container 200, so that the abutting portion 341 abuts against the inner bottom surface of the water storage container 200, thereby enabling the water adding tray 3 to be stored in the water storage container 200 in an inclined manner, effectively reducing the occupied space and improving the utilization rate of the internal space of the water storage container 200.

[0049] Since the water storage container 200 is used as an up-and-down connection structure for splicing the base and the dishwasher 100, the bottom peripheral structure of the dishwasher 100 is relatively close to the water adding port 2 of the water storage container 200. When the water adding tray 3 is pulled out from the water adding port 2, it is easily interfered by the bottom peripheral structure of the dishwasher 100, hindering the water adding operation to the water adding tray 3. For this technical problem, in another embodiment of the present application, please refer to Figures 4 to 9 , the periphery 11 of the upper cover plate 1 is inclinedly arranged, and an abutting top portion 342 is further arranged at the end portions of the side wall portions 34 of the water adding tray 3 on both sides of the water outlet 33; among them, as Figure 7 shown, a limiting portion 22 for abutting against the abutting top portion 342 of the water adding tray 3 is arranged on the inner wall of the guiding groove 13 above the water adding port 2, and a supporting platform 23 for supporting the water adding tray 3 is arranged on the inner wall of the guiding groove 13 below the water adding port 2; as Figure 4 , Figure 7 and Figure 9 shown, the guide rail 30 on the water adding tray 3 is arranged outside the side wall portion 34, and a positioning groove 301 for embedding the guide shaft 21 and limiting the extending position of the water adding tray 3 is arranged at the end portions of the guide rail 30 on both sides of the water outlet 33.

[0050] First, the outer periphery of the surrounding edge 11 of the upper cover plate 1 is inclined, so that the upper and lower parts of the water inlet 2 form a stepped structure with vertical displacement, and positioning grooves 301 are provided on the guide rails 30 of the water adding tray 3 to engage with the guide shafts 21 on both sides of the water adding tray 2. After the water adding tray 3 slides out of the water adding tray, the engagement between the positioning grooves 301 and the guide shafts 21 can be used to limit the extension position of the water adding tray 3 and effectively prevent the water adding tray 3 from falling out, and the water adding tray 3 can be rotated with the guide shafts 21 as the rotating shaft, thereby changing the extension angle of the water adding tray 3.

[0051] Secondly, the limiting portion 22 provided on the inner wall of the guide groove 13 located at the upper part of the water inlet 2 acts to limit the abutment portion 342 on the side wall portion 34 of the water adding tray 3, thereby limiting the rotation direction of the water adding tray 3, so that after the water adding tray 3 extends out of the water adding tray 2, it can only rotate downward with the guide shaft 21 as the axis, thereby increasing the distance between the water adding tray 3 and the bottom peripheral structure of the dishwasher 100. Among them, the rotatable angle setting of the water adding tray 3 after it is extended can, on the one hand, effectively reduce the interference of the bottom peripheral structure of the dishwasher 100 on the water adding tray 3, so that the user can smoothly perform the water adding operation; on the other hand, the water adding tray 3 after the rotation angle and the inclination angle of the water adding tray 3 are adjusted to a large obtuse angle, which is conducive to slowing down the flow rate of the added water flow, so that the user can better control the amount of water added.

[0052] Thirdly, the limiting portion 22 provided on the inner wall of the guide groove 13 located at the upper part of the water adding port 2, and the supporting platform 23 on the inner wall of the guide groove 13 located at the lower part of the water adding port 2, can respectively support and fix the top portion 342 of the water adding tray 3 and the bottom of the water adding tray 3, thereby forming a supporting structure for fixing the water adding tray 3 after it extends out of the water adding port 2, effectively improving the fixing effect, so that the user can add water to the water storage container 200.

[0053] On the basis of the above, please refer to Figure 9 The abutting top portion 342 of the water adding tray 3 is provided with a guide slope 343 that matches the contour of the limiting portion 22. The guide slope 343 on the abutting top portion 342 is used to abut against the inner wall of the guide groove 13, so that when the water adding tray 3 is stored, it can rotate along the guide groove 13, thereby restoring to the inclined state of sliding from the guide groove 13 into the water storage container 200, so that the water adding tray 3 can be close to the inner wall of the water storage container 200 after being stored, effectively reducing the occupied space inside the water storage container 200.

[0054] In another embodiment of the present application, the structure of the guide rail 30 is optimized. Figure 10, at the two ends of the guide rail 30 on both sides of the water outlet 33, there are sockets 302 for the guide shaft 21 to slide into the guide rail 30, and on the sockets 302 of the guide rail 30, there are check ribs 303 to prevent the guide shaft 21 from disengaging from the sockets 302. When the water adding tray 3 is installed on the water adding port 2, it can be directly inserted into the guide rail 30 through the sockets 302, and the check ribs 303 can effectively prevent the guide shaft 21 from disengaging, so as to quickly install the water adding tray 3 on the water storage container 200, effectively improving the installation efficiency.

[0055] In another embodiment of the present application, the structure of the water adding tray 3 is optimized. Please refer to Figures 7 to 9 , on the water adding cover 32 of the water adding tray 3, there is a buckle edge 321, and on the support platform 23, there is a buckle groove 231 that is buckled with the buckle edge 321. When the water adding tray 3 is stored in the water storage container 200, the buckle edge 321 provided on the water adding cover 32 of the water adding tray 3 is buckled and matched with the buckle groove 231 on the support platform 23, so that the water adding cover 32 of the water adding tray 3 can be hung on the water adding port 2, thereby fixing the storage state of the water adding tray 3.

[0056] In another embodiment of the present application, the structure of the water adding tray 3 is optimized. Please refer to Figure 11 , the outer surface of the water adding cover 32 is matched with the outer peripheral contour of the surrounding edge 11, so that the outer surface of the water adding cover 32 can completely cover the water adding port 2, making the outer peripheral surface of the surrounding edge 11 of the upper cover plate 1 flat and beautiful. Among them, on the water adding cover 32, there is also a handle groove 322 for a person's finger to insert, to facilitate the user to open and close the water adding tray 3.

[0057] In another embodiment of the present application, please refer to Figure 4 , on the water adding tray 3, there are also a plurality of splash-proof bumps 35 for preventing water splashing, and the plurality of splash-proof bumps 35 are staggered and distributed on the inner bottom surface of the water adding tray 3. Among them, the shape of the splash-proof bump 35 can preferably be a cylindrical or inverted trapezoidal bump, or can preferably be a rectangular or semi-circular rib, which can effectively prevent the added water flow from splashing on the water adding tray 3, keep the use environment hygienic, and avoid affecting the calculation of the water adding amount.

[0058] Combined with the combined application mode of the water storage container and the dishwasher, in another embodiment of the present application, the structure of the water supply system is optimized. Please refer to Figure 5 and Figure 12, by using the upper cover plate 1 located at the top of the entire water storage container 200, and the upper surface of the upper cover plate 1 being in contact with the bottom of the dishwasher 100, a water level detection device for detecting the water addition amount of the water storage container 200 is further provided on the upper cover plate 1. The water level detection device includes a float 4 and a guide post 5, and the guide post 5 extends towards the bottom of the water storage container 200; the float 4 is sleeved on the guide post 5 and can move up and down relative to the guide post 5 with the change of the water level to change the distance from the dishwasher 100 located on the upper cover plate 1; an induction member (not shown in the figure) is provided on the float 4, and an induction trigger device 6 for inductively cooperating with the induction member of the float 4 is provided at the bottom of the dishwasher 100. When the float 4 moves up and approaches the bottom of the dishwasher 100, an induction trigger effect is generated with the induction trigger device 6 at the bottom of the dishwasher 100, thereby emitting an alarm signal. The form of the alarm signal can be displayed on the control screen of the dishwasher 100, buzzer alarm, or a combination of both, effectively reminding the user to stop adding water to the water storage container 200. Therefore, no electrical components need to be provided on the water storage container 200 to avoid the problem of easy water-related damage, keeping the structure of the water storage container 200 simple and convenient to use, and effectively reducing the manufacturing cost.

[0059] For the up-and-down connection structure where the water storage container 200 is used as a base and spliced with the dishwasher 100, it is difficult to ensure the central coaxial alignment of the dishwasher 100 and the water storage container 200. The weight of the dishwasher 100 is difficult to be evenly distributed on the water storage container 200, and it is easy for the dishwasher 100 to be overturned, resulting in damage caused by the dishwasher 100 falling off the water storage container 200. For this reason, in another embodiment of the present application, the structure of the upper cover plate 1 of the water storage container 200 is optimized. Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 11 , a limit step 14 matching the shape of the bottom of the dishwasher 100 is provided inside the perimeter 11 of the upper cover plate 1. On the upper cover plate 1 of the water storage container 200, in addition to providing the perimeter 11 to surround the bottom structure of the dishwasher 100, a limit step 14 is also provided inside the perimeter 11. By using the limit step 14 to fit with the bottom structure of the dishwasher 100, the installation position of the dishwasher 100 can be effectively positioned. After the dishwasher 100 is installed on the upper cover plate 1, the central coaxial alignment of the dishwasher 100 and the water storage container 200 can be achieved, so that the weight of the dishwasher 100 can be evenly distributed on the water storage container 200, improving the supporting effect of the water storage container 200 on the dishwasher 100, ensuring the structural stability of installing the dishwasher 100 on the top of the water storage container 200, effectively preventing damage caused by uneven force leading to the easy overturning and falling of the dishwasher, and ensuring the use safety.

[0060] In another embodiment of the present application, the structure of the peripheral edge 11 of the upper cover plate 1 is optimized. Please refer to Figure 3 , Figure 6 and Figure 7 . A diversion arc surface 141 connected to the top end of the peripheral edge 11 is provided on the limiting step 14, and an inner chamfer 142 is formed at the connection between the diversion arc surface 141 and the top end of the peripheral edge 11. Among them, the diversion arc surface 141 provided on the limiting step 14 can effectively collect the overflow water on the dishwasher 100, avoiding affecting the hygiene of the usage environment. Moreover, the inner chamfer 142 formed at the connection between the diversion arc surface 141 and the top end of the peripheral edge 11 can further define the installation position of the dishwasher 100, effectively enhancing the positioning effect and playing a role in fixing the dishwasher 100.

[0061] In another embodiment of the present application, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 11 and Figure 13 . A connection part 101 for connecting with the water delivery pipe 12 is provided at the bottom of the dishwasher 100. A positioning notch 111 that is in position cooperation with the connection part 101 of the dishwasher 100 is further formed on the peripheral edge 11 of the water storage container 200. An outlet hole 15 through which the water delivery pipe 12 passes through is provided on the upper cover plate 1 located at the positioning notch 111. On the one hand, by aligning the positioning notch 111 with the connection part 101 of the dishwasher 100, one end of the water delivery pipe 12 is connected to the connection part 101 of the dishwasher 100, and the other end extends into the interior of the water storage container 200 through the outlet hole 15, thereby realizing the connection of the water supply pipeline. At the same time, the positioning notch 111 can be used as a positioning reference between the dishwasher 100 and the water storage container 200 in the water supply system, effectively defining the installation position and orientation of the dishwasher 100 installed on the water storage container 200, enabling other components between the dishwasher 100 and the water storage container 200 to be automatically aligned, such as the alignment between the water level detection device of the water storage container 200 and the induction trigger device 6 of the dishwasher 100, effectively improving the installation positioning between the dishwasher 100 and the water storage container 200, making the installation operation convenient and enabling automatic alignment. On the other hand, the positioning notch 111 can be used as a drainage port, allowing the water flowing into the upper cover plate 1 to drain from the positioning notch 111, so as to maintain the hygiene of the splicing part between the dishwasher 100 and the water storage container 200, and at the same time avoid the accumulated water affecting the induction trigger between the water level detection device and the induction trigger device 6.

[0062] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
