DETAILED DESCRIPTION OF THE INVENTION

Below is a detailed description of embodiments of the invention, examples of which are illustrated in the drawings, with the same or similar reference numbers used to denote the same or similar components or components with the same or similar purposes. The embodiments described with reference to the drawings in this document are explanatory and illustrative and are intended, in general, to provide an understanding of the proposed invention. These options for execution should not be construed as limiting the proposed invention.

Below with reference to FIG. 1-6, a top cover assembly 100 is described in accordance with embodiments of the first aspect of the present invention.

As shown in FIG. 3, the top cover assembly 100 in accordance with embodiments of the invention comprises a support portion 10, a face plate 3, and a face cover 2.

The face plate 3 is held on the support part 10, while the face cover 2 defines an opening 21 (the hole 21 is located in the center of the face cover 2), through which a portion of the face plate 3 is visible. The face cover 2 is located on the outside of the face plate 3, and encloses it in circumferential direction and closes the outer edge of the face plate 3.

In addition, the front cover 2 extends inward to a certain width in the radial direction of the front plate 3, closing the outer edge of the front plate 3. This, on the one hand, has a locking effect on the front plate 3, and, on the other hand, prevents damage to the front plate 3 , due to the contact of the front plate 3 with other surrounding products, thereby eliminating the possibility of scratching the consumer during operation.

As for the top cover assembly 100 in accordance with embodiments of the invention, closing the outer edge of the face plate 3 in the circumferential direction of the face plate 3 by the face cover 2 reduces the possibility of scratching the consumer, which ensures safety and reliability during operation. In addition, damage to the face plate 3 is prevented due to direct contact of the face plate with the surrounding product, thereby ensuring effective protection of the face plate 3.

In accordance with one embodiment of the proposed invention, the area of the face plate 3 exceeds the area of the hole 21, while the face plate 3 covers the hole 21, and the width between the outer edge of the face plate

3 and the edge of the hole 21 is 0.5-20 mm, for example 0.5 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm or 20 mm. In particular, the width over which the front cover 2 covers the outer edge of the front plate 3 can be selected in accordance with a real situation. The width over which the front cover 2 covers the outer edge of the front plate 3 is limited by the above range, reducing the possibility of scratching the consumer, which ensures safety and reliability during operation. In addition, damage to the face plate 3 is prevented due to direct contact of the face plate 3 with the surrounding product, thereby ensuring effective protection of the face plate 3.

In accordance with one embodiment of the proposed invention, the face plate 3 is made in the form of a polygon. In particular, the face plate 3 may be triangular, quadrangular, pentagonal, hexagonal, etc. (for example, octagonal, as shown in Fig. 5). The face plate 3 has many vertices and many edges. For example, if the faceplate 3 is octagonal, then it has eight vertices and eight edges, which facilitates installation and complicates the occurrence of display deviation.

According to another embodiment of the invention, the upper end of the front cover 2 is adjacent to and attached to the front plate 3, that is, the cover 2 is pressed against the upper surface of the front plate 3, and the lower end of the cover 2 is attached directly to the supporting part 10 by snap fastening. Compared with the method of connecting the front cover and front plate 3, known from the prior art, the proposed invention replaces the gluing process with a mechanical connection process, provides easy assembly and convenient operation, fewer assembly procedures, improved assembly efficiency, as well as ease and convenience of installation and dismantling.

As shown in FIG. 3, alternatively, the support portion 10 comprises an inner cover 1 and a display unit 4. The inner cover 1 is provided with a support stand, the display unit 4 being located on the inner cover 1 between the inner cover 1 and the face plate 3, while the support stand of the inner cover 1 and the display unit 4 have a supporting effect on the face plate 3.

Alternatively, the display unit 4 or the inner cover 1 limits the plurality of edges of the face plate 3. In particular, the display unit 4 can fix and limit the many edges of the face plate 3, or the inner cover 1 can fix and limit the many edges of the face plate 3, or the display unit 4 and the inner cover 1 can jointly fix and limit the many edges of the face plate 3, providing relative immobility of the face plate 3 and the inner cover 1.

According to another embodiment of the invention, the front cover 2 delimits a plurality of edges of the front plate 3 along its peripheral part, the front cover 2 surrounding the peripheral edge of the front plate 3, defining and fixing the peripheral edge (i.e., a plurality of edges continuously connected to each other) of the front plate 3 with the immobility of the front plate 3 relative to the front cover 2.

According to a possible embodiment of the invention, the lower end of the front cover 2 and the inner cover 1 or the display unit 4 are connected to each other by a snap connection. It should be understood that the front cover 2 and the inner cover 1 are connected to each other by a snap connection, the front cover 2 and the display unit 4 are connected to each other by a snap connection, or the inner cover 1 and the display unit 4 can be connected separately to the front cover 2 by snap fit. The lower end of the front cover 2 and the inner cover 1 or the display unit 4 are connected to each other by a snap connection, while the upper end of the front cover 2 is adjacent to the front cover to ensure that the face plate 3 is clamped between the cover 2 and the inner cover 1.

Next, with reference to FIG. 1-6, a top cover assembly 100 is described in accordance with embodiments of the first aspect of the present invention.

As shown in FIG. 6, the face plate 3 is made in the form of a polygon. In particular, the face plate 3 may be triangular, quadrangular, pentagonal, hexagonal, etc. (for example, octagonal, as shown in Fig. 6), while the front cover 2 surrounds the outer side of the front plate 3 in its circumferential direction and limits the hole 21 (the hole 21 is located in the center of the front cover 2), through which a part of the front plate 3 is visible .

Thus, in the node 100 of the top cover in accordance with the variants of the proposed invention, the front plate 3 is made in the form of a polygon, which is easily installed during assembly without deviations and exerts uniform stress on the plate 3, thereby eliminating its damage compared to the glass front plate 3 in the prior art.

As shown in FIG. 6, in accordance with one embodiment of the present invention, a plurality of vertices of the face plate 3 are located along its circumferential direction at certain intervals. The distances between the plurality of vertices and the inner side wall of the front cover 2 may be the same, while the distances between the plurality of vertices and the inner side wall of the front cover 2 may also be different. The front plate 3 is made essentially in the form of a rectangle, its eight vertices are indicated by the positions A, B, C, D, E, F, G and N., respectively. The vertices A, B and the vertices G, H are located on the left side of the front plate 3 and the vertices C, D and the vertices E, F are located on the right side of the face plate 3. Eight peaks A, B, C, D, E, F, G, and H are located along the circumferential direction of the face plate 3 at equal or unequal distances from the inner the side wall of the face plate 3 with the location of the face plate 3 precisely without deviation and uniform stress on it along the circumferential direction.

According to a possible example of the invention, the distance between each vertex and the inner side wall of the front cover 2, designated as L1, satisfies the following relationship 0 <L1 <5 mm. That is, the value of L1 is greater than 0, but less than or equal to 5 mm, for example, 1 mm, 2 mm, 3 mm, 4 mm and 5 mm. The specific value of L1 can be selected in accordance with existing requirements. The distance L1 is limited within the above range to prevent direct contact of each vertex with the inner side wall of the front cover 2 and to prevent separation of the front plate 3 and the front cover 2 from each other due to the excessive distance between each vertex and the inner side wall of the front cover 2.

Turning to FIG. 6, in accordance with another embodiment of the invention, the plurality of edges of the face plate 3 are connected in series and continuously along its circumferential direction. For example, with regard to the plurality of edges AB, BC, CD, DE, EF, FG, GH, ON of the face plate 3, the distance between the midpoint of each edge and the inner side wall of the face cover 2 may be the same separately, as well as the distance between the middle the point of each edge and the inner side wall of the front cover 2 may be different. For example, the distance from the midpoint of the edge AB to the inner side wall of the cover 2 is equal to or unequal the distance from the midpoint of the edge of the aircraft BC to the inner side wall of the cover 2, thereby ensuring accurate installation of the face plate 3 with the exception of deviation.

In addition, the distance between the midpoint of each edge and the inner wall of the cover 2, indicated by the symbol L2, satisfies the following relationship 0≤L2≤20 mm. That is, the distance L2 is greater than or equal to 0, but less than or equal to 20 mm, for example, 1 mm, 3 mm, 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, 17 mm, 19 mm and 20 mm The specific value of L2 can be selected in accordance with existing requirements. The distance L2 is limited within the above range to ensure that direct contact between the face plate 3 and the face cover 2 is avoided and at the same time that the face plate 3 is securely fixed to the cover 2.

The cooking apparatus S in accordance with the embodiments of the second aspect of the proposed invention comprises a top cover assembly 100 in accordance with the above embodiments.

As for the cooking apparatus S in accordance with embodiments of the invention, the distances between the vertices of the polygon formed by the face plate 3 and the inner side wall of the face cover 2 are equal, and the distances between the plurality of edges and the inner side wall of the face cover 2 are equal, so that the face plate 3 is securely and reliably fixed, and also experiences a more uniform voltage exerted on it, which prevents cracking of the edge of the face plate 3, copulating voltage. In addition, a more accurate installation of the face plate 3 is provided with the exception of the problem of deflecting the display of the cooking apparatus S and thereby improving the consumer's view.

Below with reference to FIG. 7-13, a top cover assembly 100 for a cooking apparatus in accordance with embodiments of the first aspect of the invention is described.

As shown in FIG. 9-11, the top cover assembly 100 for the cooking apparatus according to the embodiments of the first aspect of the invention comprises an inner cover 1, a face cover 2, a face plate 3 and a display unit 4. Preferably, the face plate 3 is a glass glass face plate.

In particular, the front cover 2 completely covers the inner cover 1, while the upper surface of the cover 2 limits the opening 21. The front plate 3 is located on the inside of the cover 2 and closes the hole 21 in the upper surface of the cover 2. The display unit 4 is mounted on the front plate 3. In particular, the display unit 4 is attached to the face plate 3 by means of a snap connection, at least a portion of the display unit 4 is located below the face plate 3, and the display unit 4 is made so that it faces up towards the face plate 3 to display information. For example, the display unit 4 is equipped with an indicator board with the possibility of displaying information of the indicator board in the direction of the front plate 3.

It should be noted here that the face plate in the prior art is attached to the face cover by means of an adhesive holder, and then the face plate is centered on the display unit of the face cover, which leads to a relatively long dimensional chain (face plate - adhesive holder - face cover - display block) between the front plate and the display unit, which provides ease of occurrence of deviations in alignment of the front plate with the display unit, which causes ue holes formed by the screen printing method, for the indicator lamps in the display unit boards relative faceplate.

However, in the present application, the display unit 4 is mounted directly on the face plate 3 by means of a snap connection. For example, the edge of the face plate 3 is latched with a first snap hook 42 located on the display unit 4. In other words, the display unit 4 is firmly fixed to the face plate 3 by a snap connection. Thus, the display unit 4 can have a positioning effect on the front plate, while the dimension chain between the front plate 3 and the display unit 4 can be shortened, the possibility of accumulation of errors during assembly is excluded, the displacement of the holes formed by the screen printing method for the indicator board lamps is prevented in the display unit 4 with respect to the face plate 3, and the build quality can be improved.

As for the top cover assembly 100 for the cooking device in accordance with the embodiments of the proposed invention, the display unit 4 is mounted on the front plate 3, while the dimensional chain between the front plate 3 and the display unit 4 can be shortened, the displacement of the holes formed by screen printing, for indicator board lamps in the display unit 4, relative to the face plate 3, and the build quality can be improved.

In one embodiment of the invention, as shown in FIG. 9 and 10, the inner circumferential surface of the opening 21 of the front cover 2 contains a shelf 22, while the peripheral part of the front plate 3 is adjacent to the lower surface of the shelf 22. The front plate 3 is located below the front cover 2, while the shelf 22 is adjacent to the peripheral part of the front plate 3 Thus, the shelf 22 can cover the peripheral part of the face plate 3, while the shape of the edge of the face plate 3 is not limited to the shape of the edge of the face cover 2, so that the edge of the face plate 3 can be made in the form of a curved edge from straight ineynyh segments in contrast to the prior art, when the plate 3 is located above the cover 2, and the edge of the plate 3 must correspond to the front edge of the lid 3 and to be formed into an arc shape. Thus, the cost of machining the face plate 3 can be reduced and the added value of the product can be increased.

Additionally, the face plate 3 is fixed and attached to the display unit 4, while the plate 3 is adjacent to the lower surface of the flange 22 of the front cover 2. In this case, it is not necessary to fix the front plate 3 on the front cover 2 by gluing. Accordingly, the processing and assembly efficiency can be significantly increased, cost of production is reduced, and the reliability of fixing the front plate 3 is simultaneously improved.

In some examples, as shown in FIG. 9 and 10, the shelf 22 extends obliquely and downward from the outside to the inside. For example, the shelf 22 attached to the inner surface of the front cover 2 is made in the form of an annular plate extending obliquely inward and downward. In addition, the free end of the shelf 22 is adjacent to the upper surface of the face plate 3. That is, only the free end of the inner end of the shelf 22 comes into contact with the front plate 3 and presses it, while the outer end of the shelf 22 connected to the cover 2 is located from the edge face plate 3 at a given distance.

In this case, when the display unit 4 is attached to the face plate by a snap connection, for example, when the first snap hook 42 of the display unit 4 engages the edge of the face plate 3, the engaging part of the first snap hook 42 may be placed in the gap between the shelf 22 and the face plate 3 with the exception of thereby the interaction between the engaging part of the first hook 42 and the shelf 22.

Additionally, since the shelf 22 is made in the form of a console extending obliquely downward, and only the free end of the shelf 22 presses the front plate down, an interference fit can be formed between the free end of the shelf 22 and the front plate due to the elasticity of the structure of the shelf 22. The shelf 22 is used for pressing the front plate 3 by creating a certain elastic deformation, respectively, while the degree of pressing of the front plate 3 can be increased, and the reliability of the assembly can be increased. At the same time, damage to the face plate 3 due to the hard contact of the face plate 3 with the shelf 22 can be prevented.

Preferably, as shown in FIG. 8, the front plate 3 and the shelf 22 can be made with a sealing element 5 located between them. For example, the sealing element 5 may be located between the upper surface of the plate 3 and the lower surface of the shelf 22. Thus, dirt such as dust can be prevented from entering the upper cover assembly 100 through a gap, contamination of the steam passage in the upper cover assembly 100, and the effect of contaminants on the normal operation of electrical elements in the top cover assembly 100 is prevented.

In addition, in the radially inner direction of the front cover 2, the shelf 22 extends obliquely and downward. Preferably, the bottom surface of the flange 22 may be provided with a locking rib extending downward, with a sealing element located on the inner side of the locking rib in the radial direction of the face plate. Accordingly, the locking rib can effectively limit the displacement of the sealing element and thereby prevent the deflection of the sealing element located between the shelf and the face plate. Alternatively, the sealing element is a sealing ring.

In some embodiments of the proposed invention, as shown in FIG. 12, the display unit 4 is provided with a first snap hook 42 extending upward, wherein a plurality of first snap hooks 42 are formed and spaced apart from each other about the circumferential direction of the face plate 3, and an engaging portion of the first snap hook 42 extending in the direction of the face plate 3, adjacent to its upper surface. Thus, by arranging the plurality of first snap hooks 42 in a circumferential direction from each other to engage the edge of the face plate, a strong connection of the face plate 3 and the display unit 4 can be achieved.

In addition, as shown in FIG. 12, the display unit 4 is provided with a first positioning post 43 extending upward, the plurality of first positioning posts 43 being formed and spaced apart from each other around the circumferential direction of the face plate 3. The first positioning posts 43 are made with horizontal and vertical positioning surfaces, with the front the plate 3 is supported on a horizontal positioning surface, and the peripheral part of the front plate 3 is adjacent to the inner side of the vertical positioning surface . In this case, the upper and lower surfaces of the face plate 3 are separately adjacent to the engaging part of the first latch hook 42 and to the horizontal positioning surface of the first strut 43. In this case, the engaging part of the first latch hook and the horizontal positioning surface of the first strut together provide for mounting and fixing of the face plate 3 up and down. The peripheral part of the face plate 3 is adjacent to the vertical positioning surfaces of the plurality of first mounting posts 43 arranged in the circumferential direction. Thus, the restriction of the face plate 3 in the horizontal direction can be achieved, thereby ensuring a strong connection between the face plate 3 and the display unit 4.

Preferably, the first positioning post 43 and the first snap hook 42 are spaced apart from each other and alternately with each other in the circumferential direction of the face plate 3. In addition, the first positioning post 43 and the first snap hook 42 are arranged in pairs adjacent to each other. Thus, the reliability and stability of the connection between the front plate 3 and the display unit 4 can be further improved.

Additionally, since the size of the display unit 4 in the horizontal plane is obviously smaller than the size of the face plate 3, between the face plate 3 and the inner cover 1, one side is configured to mount and fasten the display unit 4 on it, and the other side in the process assemblies are usually performed with a steam valve. Therefore, if the display unit 4 is provided with only the first snap hook 42 and the first positioning post 43 for securing the face plate 3, then the first snap hook 42 and the first positioning post 43 of the display unit 4 cannot completely surround the periphery of the face plate 3.

Thus, to further ensure the reliability of the fixing of the face plate 3, as well as to prevent its displacement and damage, preferably, as shown in FIG. 12, the inner cover 1 may be provided with a plurality of second positioning posts 11 extending upward. Moreover, the plurality of second positioning posts 11 are spaced apart from each other in the circumferential direction of the face plate 3, while the edge of the face plate 3 is supported on a plurality of first positioning posts 43 and a plurality of second positioning posts 11. A plurality of second positioning posts 11 may be located at another the end of the inner cover 1 opposite the display unit 4. Thus, as a result of the location of the plurality of first positioning posts 43 and the plurality of second positioning posts 11 at a distance d different from each other in the circumferential direction of the face plate 3, the first 43 positioning posts and the second positioning posts 11 can be used to evenly support the peripheral part of the face plate 3 along the circumferential direction. Thus, the stability of the support and the reliability of fixing the front plate 3 can be improved.

In some embodiments of the invention, the display unit 4 and the inner cover 1 are connected by a snap connection. In particular, in accordance with FIG. 11, the display unit 4 is provided with a plurality of snap hooks 41 extending downward and spaced apart from each other in the circumferential direction of the display unit 4, the inner cover 1 being provided with snap holes 14 corresponding to the hooks 41, the hook 41 being latched into the hole 14 for snapping in. Thus, the installation of the display unit 4 can be facilitated.

It should be noted here that the display unit 4 of the prior art is generally not a separate component, since the display unit 4 is a down-hole camera bounded in the front cover 2. In this case, the front plate 3 should be located above the front cover 2. However, in the present application, the display unit 4 is a separate component mounted on the inner cover 1, with the face plate 4 and the display unit 4 connected directly. Thus, the design of the front cover 2 can be simplified, and the manufacture of the front cover 3, the display unit 4 and the front plate 3 can be facilitated, the arrangement of the front plate 3 can be simplified, the dimensional chain between the front plate 3 and the display unit 4 is shortened, increased assembly efficiency and reduced manufacturing cost.

Furthermore, in accordance with FIG. 11, the inner cover 1 may be provided with a plurality of guide ribs 13 extending upward and spaced apart from each other in the circumferential direction of the display unit 4, while the display unit 4 is mounted on the inner sides of the plurality of guide ribs 13. Preferably, the inner sides of the plurality of guide ribs 13 are made in the form of wedges passing with an inclination outward from the bottom to the top. With this method, the space surrounded by the inner side surfaces of the plurality of guide ribs 13 is a horizontal portion gradually decreasing from top to bottom. In this case, the wedge-shaped guide surface of the inner side of the guide rib 13 can provide a gradual direction of the display unit 4 to a predetermined installation position, thereby improving the assembly efficiency.

In some embodiments, the front cover 2 closes the inner cover 1, the display unit 4, and the front plate 3.
