[ detailed description ] embodiments

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail. In the following embodiments, the cooking range is described by taking a gas stove as an example, and the cooking range of the present invention may also be an electromagnetic stove or an electromagnetic gas combination stove.

Referring to fig. 1 to 3, fig. 1 is a partial sectional view of a cooking stove according to an embodiment of the present invention; fig. 2 is a perspective view of a bottom case of a cooking appliance according to an embodiment of the present invention; fig. 3 is a rear view of a panel assembly according to an embodiment of the present invention.

The hob 1 comprises a bottom shell 10 and a panel assembly 20. The panel assembly 20 includes a first panel 21 and a second panel 22 which are disposed in parallel and connected to each other, and the thickness of the first panel 21 is smaller than that of the second panel 22. The first plate 21 has a first surface 21a and a second surface 21b opposite each other, the first surface 21a constituting an upper surface of the hob 1 in a use state. The bottom case 10 defines an accommodating space S. Specifically, the bottom case 10 includes a bottom wall 11 and a side wall 12, a top end of the side wall 12 is provided with an extending portion 13 extending outward and parallel to the first plate 21, an upper portion of the side wall 12 is provided with a stepped portion 15, and the stepped portion 15 has a stepped surface 150 parallel to the first plate 21. Here, it should be noted that the space inside the step portion 15 is a part of the accommodation space S. As shown in fig. 1, the first plate 21 is disposed on the bottom case 10, and the second plate 22 is at least partially located in the accommodating space S. In the use state of the hob 1, the second plate 22 is hidden.

The extension 13 and the step 15 shown in fig. 1 are integrally formed by the side wall 12. However, there may be other ways, such as the extension and the step being formed as a separate piece, riveted or screwed to the side wall. As shown in fig. 2, the bottom case 10 of this embodiment has an open square box shape, steps 15 are integrally formed on four sides of the open end, and a space is formed between adjacent steps 15, and at this time, the periphery of the portion of the accommodating space inside the steps 15 is not closed.

The first plate 21 shown in fig. 1 is a metal plate, and the second plate 22 is a glass plate. And, the thickness of the first plate 21 is smaller than that of the second plate 22. Specifically, in the present embodiment, a stainless steel plate with a thickness of 0.8mm is used as the first plate member 21, and a crystallized glass plate with a thickness of 4mm is used as the second plate member 22. The first plate 21 and the second plate 22 are connected together by means of a high temperature resistant silicone adhesive. In a further improvement of this embodiment, the periphery of the first plate 21 has a flange 210 bent toward the bottom shell 10, and when the cooking utensil 1 is installed on a table, the height H of the flange 210 constitutes the thickness of the panel assembly 20 relative to the table. In this embodiment, the height H of the flange 210 is 3.5mm. During manufacturing, the periphery of a rectangular stainless steel plate may be bent to form the flange 210. At least one liquid containing tray 30 is arranged on the first surface 21a of the first plate 21 in an adhering manner through silica gel 31.

Since the thickness of the first plate is extremely thin, the first plate is only 0.8mm in this embodiment, and if the bottom case is designed to contact with the first plate during installation, the first plate is easily pushed by the bottom case to deform due to tolerance and the like during assembly, so in this embodiment, when the first plate 21 is covered on the bottom case 10, a gap exists between the first plate 21 and the extending portion 13 at the top end of the bottom case 10, as shown in fig. 1, for example, a gap of 1.0mm to 1.5mm exists. Therefore, in a strict sense, the second plate 22 shown in fig. 1 is not completely located in the accommodating space S, but is located in the accommodating space S and a range of the accommodating space S extending perpendicularly to the first plate 21.

When the cooking utensil 1 is installed on a table top 2 (not shown in fig. 1, refer to fig. 6), the extension 13 is placed on the edge of the opening of the table top 2, the flange 210 is located on the table top 2, and the extension 13 is located on the inner side of the flange 210 and hidden in the first plate 21. Thus, the cooking utensil 1 presents a panel thickness of only 3.5mm in appearance, and the first surface 21a of the first plate 21 is a plane, and after the cooking utensil 1 is installed, the ultra-thin and flat panel is presented in appearance. And the second plate 22 of the microcrystalline glass material with high flatness and good strength is connected to the second surface 21b of the first plate 21, so that when the first plate 21 is kept to have an ultrathin and flat appearance effect, the deformation of the first plate 21 in use is effectively prevented.

Referring to fig. 1, a supporting structure for supporting the second plate 22 is disposed in the accommodating space S, and the second plate 22 is disposed on the supporting structure. Specifically, the side wall 12 of the bottom case 10 is provided with an L-shaped bracket 14, and the second plate member 22 is placed on the bracket 14 and supported by the bracket 14. The bracket 14 is attached to the side wall 12 by welding. While the brackets 14 in the embodiment of fig. 3 are attached to the side walls 12 as shown in fig. 2 by screws and the second plate 22 is attached to the brackets 14 by silicone, fig. 3 shows a plurality of brackets 14 attached to the second plate 22.

Referring to fig. 3, the first plate 21 has a reinforcing member 40 at a corner thereof, the reinforcing member 40 is disposed at each of the four corners in fig. 3, and the reinforcing member 40 is made of a strong metal material and is connected to the sidewall 12 by screwing, riveting or welding. To ensure the integrity of the first surface 21a of the first plate 21, the reinforcing member 40 may be attached to the second surface 21b by means of adhesive. In this embodiment, it is further improved that the reinforcing member 40 is provided with a groove 400, and the second surface 21b is provided with a ring of sponge (not shown) along the edge of the first plate 21, and the sponge is disposed in the groove 400 at the reinforcing member 40. When the cooking utensil 1 is installed on a table, the sponge can prevent water or soup splashed on the cooking utensil 1 from entering the inside of the cooking utensil or the inside of the cabinet.

The above is only one embodiment of the present invention, and the present invention may have further embodiments by way of alteration or modification. For example, as shown in fig. 4, fig. 4 is a perspective view of a panel assembly according to another embodiment of the present invention. The present embodiment is different from the previous embodiments in that the flanges around the first plate 21 are formed by stamping, and the two liquid containing trays 30' are formed on the first plate 21 by stamping at the same time as the first plate 21 is formed. That is, the two drip trays 30' are integrally formed on the first plate member 21.

For another example, the reinforcing member is also used to support the second plate member. Fig. 5 is a rear view of a panel assembly according to another embodiment of the present invention, as shown in fig. 5 and 6; fig. 6 is a partial cross-sectional view of a cooktop of another embodiment of the present invention placed on a countertop. The functions of the components of this embodiment that use the same numbers are the same or similar to those of the previous embodiment, and are not repeated herein, please refer to the related description above. Unlike the previous embodiment, the reinforcement 40' includes the step portion 41', the step portion 41' has the step surface 410', and the step surface 410' is used to support the second plate member 22, so that the present embodiment does not need to provide a support structure to support the second plate member. The reinforcement 40 'has a flange 420', and the flange 420 'of the reinforcement 40' is wrapped inside the flange 210 of the first plate 21, and the height of the flange 420 'of the reinforcement 40' is lower than the height H of the flange 210 of the first plate 21. Therefore, after the cooker 1 is installed on the table top 2, the thickness of the panel component 20 higher than the table top 2 is just the height H of the flanging 210 of the first plate 21, the range of the height H is 3 mm-H, and 3.5 mm-H, and the cooker 1 presents an ultrathin panel in appearance and is easy to clean.

Other modifications of the present invention are possible, for example, the first plate member 21 is an aluminum plate or a galvanized plate. The second plate 22 is a tempered glass plate or a borosilicate glass plate. Alternatively, the second plate 22 is not a glass material but a cold-rolled steel plate. The thickness of the first plate 21 is within 1mm, and the thickness of the second plate 22 is d, which is within a value range of d being not less than 4mm and not more than 8mm. The height H of the flanging of the first plate 21 is within the range of more than or equal to 3mm and less than or equal to 5mm, and the stove can have a very thin panel appearance and is easy to clean. Also for example, the step height of the step 15 at the upper portion of the side wall 12 may be designed according to the thickness of the second plate member 22, so that the second plate member 22 may be directly placed on the step surface 150 of the step 15 and supported by the step surface 150.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
