Description

Technical Field

[0001] The utility model relates to household appliances, in particular to a cooking appliance. Background Art

[0002] There are many types of products included in cooking appliances, such as electric hot pots, rice cookers, etc.

[0003] Cooking appliances all have a housing and an electric heating device arranged inside the housing. The electric heating device is connected with a wire. At present, the main wire installation method is to set an installation groove at the bottom of the housing, and then set a junction box in the installation groove. In this way, the wire on the electric heating device needs to pass through the inside of the housing, then extend to the junction box in the installation groove, and finally lead out from the junction box.

[0004] When the above cooking appliance is working, the electric heating device will generate a large amount of heat, resulting in an increase in the temperature of the housing. Since the junction box is directly attached to the installation groove, the heat of the housing will be directly conducted to the junction box through the wall of the installation groove, resulting in a relatively high temperature at the position where the junction box abuts against the wall of the installation groove, causing the wire in the junction box to have an excessive temperature rise problem, and ultimately affecting the service life of the cooking appliance.

[0005] Therefore, how to avoid the problem of excessive temperature rise of the wire in the junction box is a problem that needs to be solved. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a cooking appliance to avoid the problem of excessive temperature rise of the wire in the junction box.

[0007] The utility model is realized by adopting the following technical scheme: A cooking appliance includes a housing and a junction box. An installation groove is provided at the bottom of the housing. The junction box is located in the installation groove, and a suspension connection structure is provided between the junction box and the housing to suspend the junction box in the installation groove.

[0008] Thus, by adopting the method of suspending the junction box, the junction box is installed on the housing, thereby changing the traditional installation method in which the junction box is directly attached to the housing or the junction box is partially attached to the housing, thus avoiding the heat in the housing from being conducted into the junction box by direct transfer, and further avoiding the problem of excessive temperature rise of the wire in the junction box.

[0009] In one embodiment, an installation cavity for the wire to pass through is provided inside the junction box, and a first supporting portion for lifting the wire is provided at the bottom of the installation cavity.

[0010] In one embodiment, the first supporting portion includes a supporting platform disposed at the bottom of the installation cavity and a supporting bracket disposed on the supporting platform.

[0011] In one embodiment, a second supporting portion for lifting the junction box is disposed at the bottom of the installation groove.

[0012] In one embodiment, the second supporting portion is a rib disposed on the installation groove, and an installation position for positioning the junction box is disposed on the rib; when the junction box is placed on the installation position, the front portion and the side portion of the junction box are both in contact with the rib.

[0013] In one embodiment, the second supporting portion is prepared from phenolic foam or fiberglass material.

[0014] In one embodiment, the hanging connection structure includes a connection arm disposed on the surface of the junction box and a connection column disposed on the housing, and the connection arm is fixedly connected to the connection column.

[0015] In one embodiment, the connection column is located in the installation groove.

[0016] In one embodiment, the distance between the bottom of the junction box and the bottom wall of the installation groove is h, and 4 mm ≤ h ≤ 6 mm.

[0017] In one embodiment, the distance between the side portion of the junction box and the side wall of the installation groove is c, and 3 mm ≤ c ≤ 5 mm.

[0018] Compared with the prior art, the present utility model has the following beneficial effects: By adopting the method of hanging the junction box, the junction box is installed on the housing, thus changing the traditional installation method in which the junction box is directly attached to the housing or the junction box is partially attached to the housing, thereby avoiding the heat in the housing from being conducted into the junction box by direct transfer, and further avoiding the problem of excessive temperature rise of the wires in the junction box.

[0025] To further elaborate on the technical means and effects adopted by this application to achieve the intended purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features, and their effects according to this application. In the following description, different "one embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0026] As Figures 1-5 shown, a cooking appliance includes an outer shell 1 and a junction box 2. An installation groove 11 is provided at the bottom of the outer shell 1, and the installation groove 11 is used to place the junction box 2. Specifically, the junction box 2 is located in the installation groove 11, and a suspension connection structure is provided between the junction box 2 and the outer shell 1, so that the junction box 2 is suspended in the installation groove 11 through the suspension connection structure, so that the junction box 2 is far away from the installation groove 11 that is prone to excessive temperature rise during use. Specifically, it means that the outer surface of the junction box 2 is far away from the bottom wall and side wall of the installation groove 11 with excessive temperature rise.

[0027] It can be seen that the present utility model changes the traditional installation method in which the junction box 2 is directly attached to the outer shell 1 or the junction box 2 is partially attached to the outer shell 1 by adopting the method of suspending the junction box 2, so as to avoid the heat in the outer shell 1 from being conducted into the junction box 2 by direct transfer, and further avoid the problem of excessive temperature rise of the wires in the junction box 2.

[0028] Wherein, an installation cavity 21 is provided inside the junction box 2, and the installation cavity 21 is used for the wires to pass through. A first support part is provided at the bottom of the installation cavity 21, and the first support part is used to lift the height of the wires, so that the wires installed in the installation cavity 21 are in a lifted state, thereby reducing the contact area between the wires and the bottom wall of the installation cavity 21, so as to avoid the heat in the outer shell 1 from being conducted to the wires in the junction box 2 by direct transfer, and further avoid the problem of excessive temperature rise of the wires in the junction box 2.

[0029] It can be seen that the utility model first reduces the contact area between the junction box 2 and the installation groove 11 by hanging the junction box 2. Subsequently, by lifting the wire, the contact area between the wire and the junction box 2 is reduced. Thus, through the above two methods, the contact area between the wire and the installation groove 11 is minimized, thereby achieving the effect of minimizing heat conduction to the greatest extent and avoiding the problem of excessive temperature rise of the wire in the junction box 2.

[0030] Among them, the first supporting part includes a supporting platform 31 and a supporting bracket 32. The supporting platform 31 is arranged at the bottom of the installation cavity 21, and the supporting bracket 32 is arranged on the supporting platform 31. That is to say, the first lift of the wire height is realized through the supporting platform 31, and the second lift of the wire height is realized through the supporting bracket 32, thereby realizing two lifts of the wire height.

[0031] Among them, optionally, a second supporting part is arranged at the bottom of the installation groove 11, and the second supporting part is used to lift the junction box 2. By arranging the second supporting part, the distance between the bottom of the junction box 2 and the bottom wall of the installation groove 11 can be ensured, thereby ensuring the stability of the size of the heat insulation gap.

[0032] Among them, the second supporting part is a rib 4 arranged on the installation groove 11, and an installation position for positioning the junction box 2 is arranged on the rib 4; when the junction box 2 is placed on the installation position, the front part and the side part of the junction box 2 are both abutted against the rib 4. Thus, under the action of the rib 4, the junction box 2 is prevented from moving, and it can play the role of quickly installing and positioning the junction box 2 during installation, improving the assembly speed of the product.

[0033] Among them, the second supporting part is made of phenolic foam or glass fiber. Both phenolic foam and glass fiber are materials with low thermal conductivity, so it is beneficial to reduce heat conduction.

[0034] Among them, the hanging connection structure includes a connecting arm 5 and a connecting column 6. The connecting arm 5 is arranged on the surface of the junction box 2, the connecting column 6 is arranged on the outer shell 1, and the connecting arm 5 is fixedly connected to the connecting column 6. In one embodiment, a through hole is arranged on the connecting arm 5, a threaded hole is arranged on the connecting column 6, and the connecting arm 5 and the connecting column 6 are fixedly connected by a screw. Further, the connecting column 6 is located in the installation groove 11, that is, the connecting column 6 is hidden in the installation groove 11, thereby avoiding the connecting column 6 protruding from the surface of the outer shell 1.

[0035] Among them, such as Figure 4As shown, the distance between the bottom of the junction box 2 and the bottom wall of the installation groove 11 is h, and 4 mm ≤ h ≤ 6 mm. The inventor found through testing that problems would occur if the distance value h was too large or too small. For example, if the distance value h was too small, the heat insulation effect would be reduced, and it was not conducive to the heat dissipation in the heat insulation gap. If the distance value h was too large, the depth of the installation groove 11 would increase, which would easily interfere with the internal structure of the housing 1, thus disturbing the overall design of the product.

[0036] Similarly, as Figure 5 shown, the distance between the side of the junction box 2 and the side wall of the installation groove 11 is c, and 3 mm ≤ c ≤ 5 mm. The inventor found through testing that problems would occur if the distance value c was too large or too small. For example, if the distance value c was too small, the heat insulation effect would be reduced, and it was not conducive to the heat dissipation in the heat insulation gap. If the distance value c was too large, the width of the installation groove 11 would increase, which would easily interfere with the internal structure of the housing 1, thus disturbing the overall design of the product.

[0037] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
