As shown in fig. 1 to 11, an embodiment of the present invention provides a cooking utensil 100, which includes a bottom casing and a panel 20 disposed on the bottom casing, wherein the bottom casing includes a lower cover and an upper cover 10 connected above the lower cover, the panel 20 is bonded on the upper cover 10, and the lower cover, the upper cover 10 and the panel 20 together enclose an accommodating cavity 30.

The end 41 of the upper cover 10 near the panel 20 is provided with a flange 40, the root 42 of the flange 40 is connected with the upper cover 10, and the end 41 of the flange 40 extends toward the center of the accommodating cavity 30.

A glue groove 50 is formed in the surface of the turned-over edge 40, which faces one side of the panel 20, and the glue groove 50 is filled with glue; the glue groove 50 is located in the middle of the flange 40, and the glue groove 50 and the end 41 and the root 42 of the flange 40 are spaced from each other, and the upper cover 10 is a metal piece.

A first distance is formed between the notch edge of the glue groove 50 close to the end part 41 of the flanging 40 and the end part 41 of the flanging 40, and the first distance is not less than 3 mm.

It should be noted that the cooking appliance 100 provided in this embodiment may be a ceramic electric stove, which may be a square planar ceramic electric stove shown in the drawings, and the specific shape of the ceramic electric stove is not limited in this embodiment.

The lower cover and the upper cover 10 can be connected by a fastener, the upper cover 10 is bonded with the panel 20, a metal piece is generally selected based on the upper cover 10, the panel 20 can be a ceramic panel 20 or a microcrystalline panel 20, and the connection with the metal piece is completed by a bonding mode, so that the damage to the panel 20 is reduced. The adhesive used for bonding can be high temperature resistant adhesive, such as phenolic resin adhesive, organic silica gel or inorganic silica gel.

Since the thickness of the upper cover 10 is generally limited, the panel 20 is attached to the top end surface of the upper cover 10 with a small attachment area. In view of this, in the present embodiment, the flange 40 is disposed on one side of the upper cover 10 close to the panel 20, the end 41 of the flange 40 may extend toward the center of the receiving cavity 30, and the panel 20 is adhered to the upper surface of the flange 40, so that the connecting area between the panel 20 and the upper cover 10 may be adjusted by adjusting the distance between the end 41 and the root 42 of the flange 40, and the stability of connection between the panel 20 and the upper cover 10 is increased.

Wherein, the end 41 of the flange 40 extends towards the center of the accommodating cavity 30, and hides the end 41 of the flange 40 in the accommodating cavity 30, and the root 42 of the flange 40 is close to the outer wall surface of the upper cover 10, so that the end 41 of the flange 40 can not be seen from the outer surface of the cooking utensil 100, and the root 42 of the flange 40 is connected with the upper cover 10, thus ensuring the flatness of the outer surface of the cooking utensil 100.

In order to ensure the stable adhesion of the adhesive on the surface of the turned-up edge 40 close to the panel 20, the face of the turned-up edge 40 close to the panel 20 is provided with an adhesive groove 50, and the adhesive groove 50 can be used as a filling adhesive. In order to avoid the adhesive from overflowing to the outside, the present embodiment provides the adhesive groove 50 in the middle of the flange 40, i.e. the middle of the flange 40 in the direction from the end 41 to the root 42, and has a distance from both the end 41 and the root 42. This arrangement distributes the glue in the glue groove 50, even if there is an overflow of glue, in the area between the glue groove 50 and the end 41 of the flange 40, and between the glue groove 50 and the root 42 of the flange 40. Further, the glue groove 50 is located in the middle of the flange 40, so that the uniformity of the adhesion between the flange 40 and the panel 20 can be ensured.

And because the upper cover 10 is a metal piece, the flanging 40 connected to the upper cover 10 is also a metal piece, the glue groove 50 formed on the flanging 40 can be formed by punching or the like, and the flanging 40 is easily warped and deformed in the forming process of the glue groove 50. Because the root 42 of the flanging 40 is connected with the upper cover 10 and is restrained by the upper cover 10, the deformation condition of one side close to the root 42 of the flanging 40 is less obvious, and the end part 41 close to the flanging 40 is the free end of the flanging 40 and is not restrained by other structural parts, so the deformation condition is more serious. It is often the case that the end 41 of the flange 40 is turned up and curled, which may result in a reduced fit of the flange 40 to the panel 20, thereby seriously affecting the stability of the bonding of the flange 40 to the panel 20. In this regard, the present embodiment restricts the glue groove 50 from having a first distance between the notch edge on the side close to the end 41 of the flange 40 and the end 41 of the flange 40, and the first distance is defined to be not less than 3 mm. Referring to fig. 10, the first pitch may be a portion shown as d in fig. 10. With such a limitation, it can be avoided that the formation of the glue groove 50 causes the end 41 of the flange 40 to warp when the glue groove 50 is too close to the end 41 of the flange 40.

The first distance may be further smaller than 5mm, and when the first distance is too large, the overall length of the flange 40 may be too large, which not only consumes raw materials and increases manufacturing cost, but also causes the end 41 of the flange 40 to affect the installation of the electronic component in the receiving cavity 30. Preferably, in the present embodiment, the first pitch may be 3.5 mm. In practical use, the user can also adjust the specific value of the first distance within the above range according to needs.

Wherein the projection of the root 42 of the flange 40 on the panel 20 coincides with the edge of the panel 20. Since root portion 42 of flange 40 is connected to upper cover 10 and is close to the outer surface of cooking utensil 100, and thus end portion 41 of flange 40 is clamped between panel 20 and upper cover 10 when adhered to panel 20, the above definition can ensure that the joint between upper cover 10 and panel 20 has a high flatness near the outer surface of cooking utensil 100, and improve the appearance.

Because the glue groove 50 has an effect not only on the end 41 of the flange 40 but also on the root 42 of the flange 40 during the forming process, for this purpose, the present embodiment defines that the notch edge of the glue groove 50 on the side close to the root 42 of the flange 40 has a second distance from the root 42 of the flange 40. The second pitch is in the range of 8-15 mm. Referring to fig. 10, the second pitch may be a portion shown as e in fig. 10. When the second distance is too small, the portion of the flange 40 near the root 42 will be warped and deformed during the molding process of the glue groove 50. When the second distance is too large, the distance from the end 41 to the root 42 of the flange 40 is too large, which increases the amount of raw materials and increases the manufacturing cost. Preferably, in the present embodiment, the second pitch may be 9.5 mm. In actual use, the user can also adjust the specific value of the second distance within the above range as required.

Specifically, the groove depth of the glue groove 50 ranges from 1 mm to 2 mm. Referring to fig. 10, the groove depth of the glue groove 50 may be a portion shown in f in fig. 10, when the groove depth of the glue groove 50 is too small, the glue groove 50 contains too little glue, which affects the stability of the bonding between the panel 20 and the flange 40, and when the groove depth of the glue groove 50 is too large, the portion of the glue groove 50 located in the accommodating cavity 30 is too large, which affects the assembly of the electronic component in the accommodating cavity 30 and increases the difficulty of forming the flange 40 of the upper cover 10. Therefore, in practical use, the user can select a specific value of the groove depth of the glue groove 50 within the above range according to needs, which is not limited in this embodiment.

Referring to fig. 9, the glue groove 50 includes a glue applying groove 51 and a glue overflowing groove 52, and the glue applying groove 51 and the glue overflowing groove 52 are arranged at intervals in the direction from the end 41 of the flange 40 to the root 42 of the flange 40; the glue applying groove 51 and the glue overflowing groove 52 are communicated with each other. It should be noted that the glue applying groove 51 may serve as a main groove for filling glue, and the glue overflowing groove 52 may not be filled with glue during the initial glue filling operation. In order to ensure the sufficient amount of the glue, the glue filling groove 51 can be filled with the glue, and in the process of attaching the panel 20 to the flange 40, the glue in the glue filling groove 51 overflows in the extrusion process of the panel 20, and the overflowed glue can be contained in the glue overflowing groove 52, so that the glue overflowing is prevented from leaking to the outer surface of the cooking utensil 100 or the accommodating cavity 30.

The extension of glue groove 51 and glue overflow groove 52 in the direction from end 41 to root 42 of flange 40 determines the amount of glue contained. The extension length of the glue groove 51 may be a portion shown in a of fig. 10, and the extension length of the glue overflow groove 52 may be a portion shown in b of fig. 10. The value range of a and b can be 2-6mm, and the value range of a and b can be equal or unequal. Preferably, in this embodiment, a and b are equal and 3 mm. In actual use, the user can adjust the specific values of a and b within the above ranges as desired.

Wherein, in order to guarantee that the viscose in the gluing groove 51 flows to the glue overflow groove 52, a region for communicating the gluing groove 51 and the glue overflow groove 52 is arranged between the gluing groove 51 and the glue overflow groove 52, a stopping bulge 53 is arranged between the gluing groove 51 and the glue overflow groove 52, and a fourth distance is arranged between the end part 41 of the stopping bulge 53 and the notch of the glue groove 50. The panel 20 abuts against the notch of the glue groove 50, and a gap is formed between the panel 20 and the end part 41 of the stopping projection 53, and the gap is communicated with the glue pouring groove 51 and the glue overflowing groove 52.

Specifically, the height of the stopper projection 53 may be in the range of 0.2 to 0.5 mm. The fourth pitch may range from 0.5 to 0.8 mm. In the direction from the end 41 to the root 42 of the flange 40, the extension length of the stopping protrusion 53 may range from 2mm to 6mm, the extension length of the stopping protrusion 53 may be the portion c shown in fig. 10, and in this embodiment, the value of c may be 2 mm. In actual use, the user can adjust the specific value of c within the above range as desired.

It should be noted that the stopping protrusion 53 can serve to isolate the glue applying groove 51 and the glue overflowing groove 52, so as to prevent all the glue in the glue applying groove 51 from flowing into the glue overflowing groove 52, and thus, the adhesion between the panel 20 and the flange 40 is not affected. The fourth distance between the end 41 of the position-limiting protrusion and the notch of the glue groove 50 may be a vertical straight line distance therebetween, and may be a portion shown as g in fig. 10. When the fourth distance is too small, the gap is too small, the connectivity between the glue applying groove 51 and the glue overflowing groove 52 is affected, so that the process that glue overflows to the glue overflowing groove 52 is affected, and when the fourth distance is too large, a large amount of glue in the glue applying groove 51 flows to the glue overflowing groove 52, the glue amount in the glue applying groove 51 is affected, and the bonding stability of the panel 20 and the flanging 40 is reduced. Therefore, in practical use, the user can adjust the specific value of the fourth distance according to the requirement. Preferably, in the present embodiment, the fourth pitch may be 0.5 mm. The height of the stopper projection 53 may be 0.5 mm.

Wherein, because the end 41 of the flange 40 is close to the accommodating cavity 30, in order to prevent the excessive glue from flowing into the accommodating cavity 30 and affecting the operation of the electronic component in the accommodating cavity 30, the excessive glue groove 52 may be disposed on the side of the glue applying groove 51 close to the end 41 of the flange 40. The arrangement is such that the adhesive overflowing from the adhesive applying groove 51 flows into the accommodating chamber 30 and can be contained in the adhesive overflowing groove 52.

Further, referring to fig. 9 and 10, the adhesive overflowing from the adhesive applying groove 51 also flows toward the root 42 of the flange 40 and onto the outer wall surface of the cooking utensil 100, and gathers at the connection of the middle panel 20 and the upper cover 10. To address this problem, the glue overflow groove 52 may be disposed on a side of the glue applying groove 51 near the root 42 of the flange 40. The arrangement is such that the glue overflowing from the glue applying groove 51 flows towards the root 42 of the flange 40 and is contained in the glue overflowing groove 52.

And a third distance is formed between the edge of the notch of the glue overflowing groove 52 close to the root part 42 of the flanging 40 and the root part 42 of the flanging 40, and the range of the third distance is 3-6 mm. The third distance may be a portion h shown in fig. 10, when the third distance is too large, the length between the end portion 41 and the root portion 42 of the flange 40 may be increased, which may increase the amount of the raw material of the flange 40, and when the third distance is too small, which may cause a problem that the side of the flange 40 near the root portion 42 may be warped during the molding of the glue groove 50. And the possibility of the spilled glue running to the outer surface of the cooking appliance 100. Therefore, in practical use, the user can adjust the specific value of the third distance within the above range according to the requirement. Preferably, in the present embodiment, the third pitch may be 4 mm.

Specifically, the glue overflowing from the glue applying groove 51 is limited to the first distance, which is the distance between the edge of the notch of the glue applying groove 51 on the side close to the root 42 of the flange 40 and the root 42 of the flange 40. The distance between the edge of the notch of the glue applying groove 51 on the side close to the end 41 of the flange 40 and the end 41 of the flange 40 is the second distance.

Referring to fig. 9, a guide slope 54 is provided at the notch of the glue groove 50. Such an arrangement can facilitate filling of the adhesive into the adhesive groove 50 while increasing the contact area of the adhesive with the panel 20 in the adhesive groove 50, thereby increasing the firmness of the bonding. The specific inclination of the guiding inclined plane 54 can be adjusted according to the requirement, and the embodiment is not limited thereto.

Further, the burring 40 is integrally formed with the upper cover 10. This may improve the structural strength of the cooking appliance 100 while reducing the assembly difficulty. The flanging 40 and the upper cover 10 are both metal pieces, and the end part 41 of the upper cover 10 close to one side of the panel 20 can be bent through stamping, so that the flanging 40 can be formed, and the forming difficulty of the flanging 40 is reduced.

Referring to fig. 9, as an achievable embodiment, the flange 40 is recessed towards the side remote from the panel 20, forming a glue groove 50. The flange 40 may be formed by bending the flange 40 near the glue groove 50 toward the side away from the panel 20 and forming the glue groove 50. The side of the flange 40 facing away from the panel 20 also has a projection that matches the glue groove 50. This is suitable for the case where the thickness of the flange 40 is small.

Referring to fig. 11, as another realizable embodiment, the surface of cuff 40 facing the side of panel 20 is provided with a recess forming glue groove 50. The flange 40 may be cut out by cutting a portion of the flange 40 on the side of the flange 40 adjacent to the panel 20, thereby forming a recess. At this time, the surface of the cuff 40 on the side away from the panel 20 does not have the projection of the above embodiment, but has a planar structure. This is suitable for the case where the thickness of the flange 40 is large.

In practical use, a user can select any one of the two manners as required to improve the flexibility of the structure of the glue groove 50.

Further, the surface of the flange 40 near the panel 20 is a plane. The portion of the flange 40 on the side close to the panel 20, where the glue groove 50 is not provided, may be a plane and extend in the horizontal direction, so that the fitting degree of the panel 20 and the upper cover 10 may be improved, thereby improving the stability of the installation of the panel 20.
