[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0026] like Figures 1-3As shown, a dishwasher includes a door 7 and a main body 6. The door 7 is hinged to the main body 6. The main body 6 includes an outer shell and an inner tub placed inside the outer shell. The inner tub has a washing chamber inside. The outer shell includes a cover plate 1. The cover plate 1 includes a heat-resistant part 2 and a frame part 11 arranged around the heat-resistant part 2. The heat-resistant part 2 and the frame part 11 are integrally connected. The door 7 rotates on the main body 6, which is convenient to open or close from the side of the main body 6. When the door 7 is opened, the outer shell of the main body 6 is open, and its inner tub forms a washing chamber, which is convenient to put in dishes and utensils. After the door 7 is closed, the dishwashing work can be carried out. After the heat-resistant part 2 and the frame part 11 are integrally connected, the cover plate 1 is installed on the top of the outer shell. It blocks the heat of the washing chamber through the heat-resistant part 2. At the same time, the cover plate 1 can also place items, which serves as a support for the items and also serves as a heat insulation support.

[0027] A square hole is provided in the middle of the cover plate 1, and the frame part 11 is the edge of the square hole. That is, the frame part 11 serves to connect with the heat-resistant part 2. The square hole can be selected in different shapes, such as parallelogram, trapezoid, etc. A slot 3 is provided on the side of the frame 11 near the heat-resistant part 2. At least one edge of the heat-resistant part 2 is embedded in the slot 3 to integrally connect the frame 11 and the heat-resistant part 2. The heat-resistant part 2 is placed in a square hole. The slot 3 is provided on the side wall of the cover plate 1 located in the square hole and at least covers part of the edge of the heat-resistant part 2 for integrally connecting the cover plate 1 and the heat-resistant part 2. The number of square holes can be multiple, such as two or three, and each square hole can be provided with one heat-resistant part 2. In this application, it is preferred to provide only one square hole on the cover plate 1. One, two, or three sides of the heat-resistant part 2 can be placed in the slot 3. Each side can be partially placed in the slot 3 and the other part exposed. Alternatively, the outer edge of the heat-resistant part 2 can be completely wrapped in the slot 3, so that the cover plate 1 and the heat-resistant part 2 are integrally connected. The whole process does not require the use of a sealing gasket. The heat-resistant part 2 is directly installed on the cover plate 1 without the need for the original glue and nailing methods, which reduces the cost of glue application and avoids the testing problems caused by nailing.

[0028] As one embodiment of this application, such as Figure 2 and Figure 3 As shown, the heat-resistant part 2 and the frame part 11 are connected by integral injection molding. During the injection molding process of the cover plate 1, the heat-resistant part 2 is placed in the mold of the cover plate 1. As the injection process progresses, the injection molding material covers the heat-resistant part 2 in liquid form until the injection molding material cools down, and the cover plate 1 and the heat-resistant part 2 are integrally formed. This method eliminates the need to set a sealing gasket around the heat-resistant part 2, avoids the original glue and nailing methods, greatly improves production cost and production efficiency, and also ensures the product yield.

[0029] When the cover plate 1 is injection molded, the heat-resistant part 2 is designed according to the injection mold so that the slot 3 can partially cover the edge of the heat-resistant part 2. This solution can be adjusted according to the stress on the heat-resistant part 2. For areas with concentrated stress, the area of ​​the slot 3 covering the edge of the heat-resistant part 2 can be increased. For areas with low stress requirements at the edge of the heat-resistant part 2, the area of ​​the slot 3 covering the edge of the heat-resistant part 2 can be reduced or the slot 3 can not cover the edge of the heat-resistant part 2. For areas not covered by the slot 3, they can be sealed by applying glue. In this application, the slot 3 completely covers the edge of the heat-resistant part 2, improving the sealing performance between the heat-resistant part 2 and the cover plate 1, and can be applied to different scenario requirements.

[0030] like Figure 3 As shown, in order to improve the fit between the heat-resistant part 2 and the frame part 11, the cross-section of the slot 3 is U-shaped, which can completely cover the upper and lower sides of the heat-resistant part 2, so that the heat-resistant part 2 can be directly and integrally connected to the cover plate 1, thereby improving the connection stability between the two. In addition, the cross-section of the slot 3 can also be C-shaped, trapezoidal, etc., which can be formed by injection molding of the cover plate 1 according to the edge shape of the heat-resistant part 2.

[0031] like Figure 1 and Figure 2 As shown, in this application, the heat-resistant part 2 is made of tempered glass. The tempered glass improves the overall structural strength of the cover plate 1, withstands high temperatures, and can be injection molded with the cover plate 1, eliminating the need for nailing or gluing as two-part connection processes, simplifying the production process and reducing manufacturing costs. Simultaneously, the printing process for tempered glass is convenient and simple, easily meeting the diverse appearance requirements of household appliances. Furthermore, the outer surface of the tempered glass is crystal clear, enhancing the visual effect. The thickness of the tempered glass is 4mm to 7mm, preferably 5mm to 6mm, providing sufficient strength and heat resistance to effectively prevent the door from deforming or breaking during high-temperature washing. In addition, the heat-resistant part 2 can also be made of insulated glass, coated glass, or PC board.

[0032] like Figure 2 As shown, in order to improve the structural strength of the cover plate 1, the area of ​​the heat-resistant part 2 occupies at least 60% of the area of ​​the cover plate 1, so that the tempered glass plate, insulated glass, coated glass or PC plate mentioned above can occupy most of the cover plate 1. On the one hand, it can reduce the use of injection molding materials, and on the other hand, it can increase the overall structural strength.

[0033] like Figure 2 and Figure 3As shown, the upper lip of the slot 3 is provided with a guide surface. The lower part of the guide surface is in contact with the heat-resistant part 2. The guide surface can be a slope or an arc surface. The lower part of the slope or arc surface is close to the heat-resistant part 2. The upper lip is the edge of the slot 3 along the direction perpendicular to the large surface of the cover plate 1, so that the slope or arc surface of the upper lip can transition to the heat-resistant part 2. After the cover plate 1 is installed, the height difference between one side of the cover plate 1 and the heat-resistant part 2 is reduced, which can improve the aesthetics of the cover plate 1 and also facilitate the stable placement of items on the cover plate 1. The guide surface prevents items from falling out of the heat-resistant part 2.

[0034] like Figure 2 and Figure 3 As shown, the outer shell includes side plates 61 surrounding the main body 6. Several limiting blocks 5 are provided around the periphery of the frame portion 11. The limiting blocks 5 are connected to the side plates 61 and are located at the lower lip of the slot 3, corresponding to the upper lip. The cover plate 1 is located on one side of the lower lip for installation and positioning, facilitating connection with different devices. A snap-fit ​​connection is preferred.

[0035] like Figure 3 As shown, a support block 4 is provided at at least one corner of the cover plate 1. The support block 4 is connected to the side plate 61, and the side of the cover plate 1 is attached to the side plate 61 to provide support. The support block 4 can be fixed to the side plate 61 by means of bolts, rivets or pins to meet the requirements of the dishwasher top cover. The limiting block 5 is a rib integrally connected to the frame part 11. The frame part 11 is provided with ribs on at least three sides. The ribs are clamped and fixed to the inner wall of the side plate 61 to limit the position of the cover plate 1 and the side plate 61. In this application, it is preferable to provide support blocks 4 at the two corners on the rear side of the cover plate 1 and fasten them to the side plate 61 through the support blocks 4. The ribs are provided on the front side and the left and right sides of the frame part 11 to ensure that the front of the cover plate 1 can be pre-fixed with the side plate 61, and the rear side is tightened by fasteners.

[0036] The cover plate 1 of this application can serve as the top cover of a dishwasher. Since the washing chamber temperature of the dishwasher is too high, the heat-resistant part 2 can provide heat insulation for the dishwasher. At the same time, the sealing requirements of the top cover of the dishwasher are lower than those of the door body of the dishwasher. Therefore, the cover plate 1 of this application fully meets the sealing requirements. The edge of the heat-resistant part 2 is integrally connected with the slot 3, which improves the impact resistance and stress bearing strength of the heat-resistant part 2, making it easy to stack items on the top cover of the dishwasher and meeting daily needs.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
