[0031] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0032] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or server including a series of steps or units does not necessarily have to include only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device.

[0033] The door panel structure of the dishwasher is generally as shown in Figure 1 The connecting line 11 of the preset element 10 passes through the outlet hole 21 on the door panel body 20 to connect with the target element outside the door panel body 20, which makes the water droplets inside the dishwasher easily enter the door panel body 20 along the outlet hole and flow to the position of the preset element 10 along the connecting line 11, resulting in water entering the preset element.

[0034] Based on this, the door panel structure of the dishwasher according to an example embodiment of the present disclosure is provided, as shown in Figure 2 The door panel structure includes a door panel body 20 and a preset element 10. The door panel body 20 includes a first surface 22, and the preset element 10 is arranged on the first surface 22.

[0035] The preset element 10 can be generally an element for user interaction, including but not limited to a display, a control panel, a button, etc., facilitating the user to control the operation of the dishwasher and master the cleaning process of the dishwasher. Therefore, the first face 21 can be a face of the door panel body 20 facing the outside of the dishwasher, specifically a face facing the user.

[0036] For example, if the dishwasher is a conventional built-in dishwasher, the first face 21 of the door panel body 20 is in the direction of the cabinet opening in which the door panel body 20 is built in. If the dishwasher is a sink dishwasher, the first face 21 of the door panel body 20 is a face facing upward.

[0037] The door panel body 20 further comprises a second face 23 disposed in a first preset positional relationship with the first face 22, and the inside of the door panel body 20 is provided with a guide pipe 30.

[0038] The first preset positional relationship can be an adjacent positional relationship, i.e., the second face 23 is disposed on a face of the door panel body 20 adjacent to the first face 22, or can be an opposite positional relationship, i.e., the second face 23 is disposed on a face of the door panel body 20 opposite to the first face 22.

[0039] The first end 31 of the guide pipe 30 is in communication with the preset element 10, and the second end 32 of the guide pipe 30 is disposed on the second face 23 and in communication with the outside of the door panel body 20. The guide pipe 30 is provided with a first drain hole 33. The connecting line 11 of the preset element 10 passes through the guide pipe 30 and is guided to the outside of the door panel body 20 via the guide pipe 30.

[0040] When the dishwasher is in a working state, water inside the dishwasher can enter the door panel body 20 along the connection between the guide pipe 30 and the second face 23 of the door panel body 20. Since the first end segment 31 of the guide pipe 30 connected to the preset element 10 is disposed on the first face 22 of the door panel body 20, and the second end 32 of the guide pipe 30 connected to the door panel body 20 is disposed on the second face 23 of the door panel body 20, there is a positional difference between the two ends of the guide pipe 30 from the first end 31 to the second end 32, which makes it difficult for the water entering the door panel body 20 to directly flow to the position of the preset element 10. At the same time, the guide pipe 30 is provided with the first drain hole 33, so that the water entering the door panel body 20 via the connecting line 11 can directly flow into the cavity of the door panel body 20 via the first drain hole 33, further effectively reducing the probability of water flowing to the preset element 10, thereby effectively improving the service life of the element on the dishwasher.

[0041] In an embodiment, the guide pipe 30 comprises at least one guide portion 34.

[0042] When the at least one guide portion 34 comprises at least two guide portions 34, the connection between two adjacent guide portions 34 among the at least two guide portions 34 is at a preset angle.

[0043] The preset angle can be set according to the number of guide portions 34 and the positional relationship between the first end and the second end of the guide tube, which is not particularly limited here. For example, Figure 3 As shown in the figure, the connection between two adjacent guide portions 34 is at an angle of 90°.

[0044] Similarly, in the guide tube 30, the connection between the guide portion 34 close to the first end 31 and the preset element 10 is at a preset angle, and the connection between the guide portion 34 close to the second end 32 and the second surface 23 is at a preset angle.

[0045] In addition, at least one first drainage hole 35 is arranged on the guide portion 34 among the at least one guide portion 34. Similarly, reference can be made to Figure 3 At least one first drainage hole 35 is arranged in the entire guide tube 30, and in order to accelerate the drainage efficiency and reduce the probability of water entering, one first drainage hole 35 can be arranged on each guide portion 34, or one first drainage hole 35 can be arranged every interval of guide portions 34.

[0046] In this embodiment, the purpose of arranging multiple guide portions 34 is to design the guide tube 30 as a folded track, so that the water flow path in the guide tube 30 is more complex and it is not easy for water to quickly flow to the switch plate. When no first drainage hole is encountered, water accumulates in the wiring track, and when the amount of accumulated water increases, it flows to the first drainage hole and is then discharged from the first drainage hole. This effectively reduces the probability of water entering the connection between the second end 32 and the second surface 23 to the preset element 10, greatly reducing the water entry failure rate of the preset element 10.

[0047] In one embodiment, the first end 31 of the guide tube 30 and the second end 32 of the guide tube 30 are arranged at a preset direction.

[0048] As shown in the figure, Figure 3 The preset direction can be arranged in the up-down direction, specifically, the first end 31 is located at the top and the second end 32 is located at the bottom. The purpose of such arrangement is to cause a positional difference between the second end 32 and the first end 31, so that water entering the door panel body 20 is not easy to directly reach the position of the preset element 10 along the guide tube 30, resulting in water entering the preset element 10.

[0049] In addition, the positional difference between the first end 31 of the guide tube 30 and the second end 32 of the guide tube 30 satisfies a preset length range. The preset length range can be set according to actual conditions, which is not particularly limited here.

[0050] In one embodiment, a first sealing pad (not shown in the figure) is arranged at the connection between the connecting line 11 and the preset element 10, which can fix the connecting line 11 while preventing water from entering the preset element 10 along the connecting line 11.

[0051] In one embodiment, a second sealing pad (not shown in the figure) is arranged at the connection between the connecting line 11 and the second end 32 of the guide pipe 30, which can fix the connecting line 11 while preventing water from entering the guide pipe 30 along the connecting line 11.

[0052] In one embodiment, the material of the guide pipe 30 includes a metal material or a plastic material. The metal material can improve the firmness of the guide pipe 30, while the plastic material can prevent rusting and improve the durability of the guide pipe 30. In the present embodiment, no particular limitation is made, and it can be freely selected.

[0053] In addition, in addition to the above arrangement, the guide pipe 30 can also be a hollow structure.

[0054] In one embodiment, referring to Figure 3 , the door panel body 20 further includes a third face 24 arranged in a second preset positional relationship with the first face 22, and the third face 24 is provided with a drainage assembly 25.

[0055] The second preset positional relationship can be a relative positional relationship, i.e., the third face 24 is arranged on the door panel body 20 opposite to the first face 22. Water entering the door panel body 20 can fall into the drainage assembly 25 arranged on the third face 24 and be drained out of the door panel body 20 along the drainage assembly 25.

[0056] In a specific embodiment, the drainage assembly 25 includes a detachable water accumulation groove. The bottom of the water accumulation groove is detachable towards the outside of the door panel body 20, and the user can detach the bottom of the water accumulation groove for drainage.

[0057] In a specific embodiment, the drainage assembly 25 includes a flow guide groove, and the drainage port of the flow guide groove is open to the outside of the door panel body 20. Water falling into the flow guide groove will be drained out of the door panel body 20 along the drainage port of the flow guide groove.

[0058] In a specific embodiment, the drainage assembly 25 includes a second drainage hole. Water droplets falling in the door panel body 20 will fall onto the third face of the door panel body and be drained out of the door panel body 20 through the second drainage hole arranged on the third face.

[0059] In one embodiment, the door plate body 20 can also not be provided with the drainage assembly 25, and the water entering the door plate body 20 can be directly volatilized from the connection of each component of the door plate body 20 to the external environment to achieve drainage. Since the water entering the door plate body 20 is small in most cases, the water entering the door plate body 20 can be smoothly volatilized.

[0060] In one embodiment, the door plate body 20 can be a tempered glass material. The tempered glass material can facilitate the user to control the working progress of the dishwasher in real time.

[0061] An example embodiment of the present disclosure is a dishwasher, referring to Figure 4 The dishwasher includes a dishwasher body 41 and a door plate structure 42 of the dishwasher as in the above embodiment, and the door plate structure 42 is installed at the opening of the dishwasher body 40.

[0062] Specifically, the first face 22 of the door plate body 20 on the door plate structure 42 faces the opposite direction of the dishwasher body 41, i.e., the external direction, so that the user can interact with the preset element.

[0063] In one embodiment, the dishwasher is preferably a sink dishwasher, which integrates the common sink with the dishwasher, leaves the space of the traditional dishwasher to other kitchen electrical appliances, and greatly improves the kitchen utilization efficiency. At the same time, the sink is integrated and installed without disassembling the cabinet and changing the water and electricity, and the original sink is used, which is convenient to install and saves engineering cost.

[0064] Most of the sink dishwashers are arranged on the countertop and arranged side by side with the sink, so that the opening of the dishwasher body 41 of the sink dishwasher faces upward, the first face 22 also faces upward, and the third face 24 arranged in the second preset positional relationship with the first face faces downward. The water droplets entering the door plate structure 42 can fall on the third face 24 and be discharged through the drainage assembly arranged on the third face 24.

[0065] The dishwasher body 41 of the sink dishwasher can include a sink body of the dishwasher and a working area below the sink body.

[0066] A drain port and a drain valve communicating with the drain port are arranged at the lower part of the sink body, and a spray arm is arranged at the bottom of the sink body of the dishwasher.

[0067] A water pump, a water pump motor, and an electric control board are also arranged in the working area at the lower part of the sink body. The water pump is used to drive the water pump to circulate the water between the spray arm and the sink body of the dishwasher, the water pump motor of the door plate structure 42 is used to drive the water pump to work, and the electric control board is used to control the working state of the water pump motor and the drain valve.

[0068] At this time, the target element can be an electric control board, and the preset element can be a touch panel. The electric control board is electrically connected to the touch panel through a connecting line of the touch panel. The touch panel collects a user's setting of the working mode and sends the working mode to the electric control board. The electric control board controls the water pump motor and the drain valve according to the corresponding working mode. The water pump motor and the drain valve have a one-to-one correspondence with the working mode. For example, if the user selects the working mode of the water pump motor as "quick cleaning mode", at this time, the water pump motor will control the water pump to stop working after 15 minutes, and at the same time, the drain valve will drain water after 15 minutes.

[0069] If the water droplets cannot be smoothly drained after entering the door plate structure 42, the water droplets may continue to accumulate, eventually causing the preset element 10 to have the risk of water ingress. The following method is also provided in the embodiment to process the door plate structure 42.

[0070] In a specific embodiment, the dishwasher is also provided with a drain pipe connected to the drain valve to drain the wastewater in the dishwasher to the sewer pipe. At the same time, on the basis that the door plate body in the above embodiment is also provided with a flow guide groove, the drain port of the flow guide groove can be connected to the drain port of the backflow groove. The flow guide groove can directly drain the accumulated water in the door plate structure 42 out of the dishwasher through the drain pipe, further reducing the risk of water ingress of the preset element.

[0071] In a specific embodiment, the dishwasher is also provided with a drying device inside the tank body, which is used to dry the tableware placed inside the tank body of the dishwasher. At the same time, on the basis that the door plate body in the above embodiment is also provided with a second drain hole, under the action of the drying device, the accumulated water inside the door plate body 20 is dried, thereby reducing the risk of water ingress.

[0072] Specifically, the drying device includes a fan, and the drying device is used for heating drying. In order to avoid heat loss, the door plate structure 42 of the dishwasher is in a closed state when the drying device is working, so that the inside of the tank body is separated from the outside of the dishwasher, and the water vapor stays inside the tank body. After the heating drying of the dishwasher is completed, the dishwasher can also be dehumidified. During the dehumidification stage, the water vapor in the dishwasher diffuses to the outside of the tank body, and at this time, the water vapor of the door plate structure 4242 also diffuses to the outside of the tank body together with the water vapor in the dishwasher. Especially when the temperature inside the tank body is greater than the temperature of the external environment of the dishwasher, the temperature difference can realize further evaporation of the residual water vapor on the surface of the tank body, thereby realizing further drying of the tableware in the tank body.

[0073] When the drying device enters the heating and drying stage, if the fan is in the open state, the open state of the fan is maintained; when the drying device enters the heating and drying stage, the fan is in the shutdown state, the fan is controlled to start and run at a set speed, the running speed of the fan can be a fixed speed, or can be specifically determined according to the temperature of the tableware when entering the heating and drying stage, and the fan is mainly used to accelerate the flow of gas in the groove and accelerate the evaporation of water droplets on the surface of the tableware in the groove; in the dehumidification stage, the door plate structure 42 is opened, and the fan can be in the open state or in the closed state; the opening degree of the door plate structure 42 can be a fixed opening degree, or the actual opening degree of the door plate structure 42 can be determined according to the actual drying state. Here, the opening degree of the door plate structure 42 represents the size of the channel formed between the edge of the door plate structure 42 after opening and the edge of the corresponding opening on the dishwasher main body 4141, which is mainly for the diffusion of water vapor from the inside of the groove to the outside. The larger the opening degree, the larger the channel formed, and the more water vapor that can pass through. By first opening the fan to perform drying action on the tableware in the groove, and then opening the door plate structure 42 when the drying action of the tableware reaches the set condition, the water vapor in the groove can diffuse to the outside of the groove, realizing further drying of the tableware. Due to the effect of the fan accelerating the air convection of the washing cavity, the water on the surface of the tableware can evaporate into the air in a short time, avoiding the water remaining on the surface of the tableware, so as to ensure that the tableware can achieve better drying effect. Further, when the drying of the tableware reaches the set condition, the door body of the washing cavity is opened, a large amount of water vapor in the groove diffuses to the outside of the washing cavity through the gap formed by the opening of the door plate structure 42, avoiding the high humidity in the groove, thereby realizing the shortening of the drying time of the dishwasher.

[0074] In one embodiment, a target element (not shown in the figure) is further arranged in the dishwasher main body 41, and the target element is electrically connected with the preset element 10. Specifically, the two are electrically connected through the connecting line 11 of the preset element 10.

[0075] In addition, the preset element provided in the embodiment includes but is not limited to a display, a control panel, a button, etc., and the target element includes but is not limited to a controller, a power supply, a motor, etc., which can be combined according to actual conditions.

[0076] It should be noted that the above-mentioned sequence of the embodiments of the present disclosure is only for description, and does not represent the advantages and disadvantages of the embodiments. The above describes specific embodiments of the present disclosure. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be executed in an order different from that in the embodiments and still achieve the desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
