Description

Technical Field

[0001] This invention relates to the field of small household appliances, and more specifically, to a housing assembly and a cooking appliance. Background Technology

[0002] Cooking appliances in related technologies generally include a housing assembly, which includes the housing and a control panel. Users can operate the cooking appliance to perform various cooking tasks through the control panel.

[0003] The outer casing is typically made of metal. During manufacturing, to install the panel assembly, the metal plates must first be connected into a ring, and then mounting holes are made in the ring to install the panel assembly.

[0004] This approach makes the manufacturing process of the housing components complex and inefficient. Summary of the Invention

[0005] The main objective of this invention is to provide a housing assembly and a cooking appliance to solve the problem of low processing efficiency of housing assemblies in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a housing assembly is provided, comprising: a housing formed by a plate having two free ends that are not connected to each other to form a mounting opening; and a panel assembly disposed at the mounting opening and connected to the two free ends of the plate.

[0007] By applying the technical solution of this invention, when processing the outer shell, a plate of a predetermined length is cut, and then the plate is shaped into the required shape of the outer shell. An installation opening is directly formed between the two free ends of the plate, and the panel assembly is placed at the installation opening. The two free ends of the plate are then connected to form a single outer shell assembly. Compared with the processing method mentioned in the prior art, this method reduces the following steps: first, it avoids connecting the plates into a ring; second, it avoids opening installation holes in the plate for mounting the panel assembly. Therefore, it reduces the processing steps of the outer shell assembly and improves the production efficiency of the outer shell assembly. Furthermore, since the length of the installation opening needs to be removed when cutting the plate, the amount of material used in the plate can be reduced, thereby lowering the production cost of the outer shell processing.

[0008] Furthermore, the panel assembly includes an interconnected panel and a back cover. The panel has multiple button areas, and the portions of the housing located on both sides of the mounting opening are sandwiched between the panel and the back cover. In the above structure, the portions of the housing located on both sides of the mounting opening are sandwiched between the panel and the back cover, allowing the housing and panel assembly to be connected more tightly, forming a closed whole, thereby ensuring that the housing assembly has sufficient strength.

[0009] Furthermore, the rear cover includes a rear cover body and support plates connected to both sides of the rear cover body, with the support plates fitting against the inner surface of the outer shell. In the above structure, the support plates of the rear cover are located inside the outer shell, the rear cover body extends into the mounting opening, the panel covers the outer side of the rear cover body, and the inner wall of the circumferential edge of the panel abuts against the outer wall of the outer shell. When the rear cover and the panel are clamped together, the support plates can apply an outward resisting force to the inner surface of the outer shell, and the inner wall of the panel can apply an inward resisting force to the outer surface of the outer shell, thereby clamping the outer shell between the panel and the rear cover, allowing the panel assembly to be tightly connected to the outer shell. In addition, the fitting of the support plates against the inner surface of the outer shell increases the area supporting the outer shell, further improving the strength of the outer shell assembly.

[0010] Furthermore, the housing assembly also includes a middle plate disposed at the upper edge of the housing, the middle plate including a mounting plate, a rear cover located between the mounting plate and the front panel, and fasteners passing through the mounting plate, the rear cover, and the front panel to connect the housing, the front panel assembly, and the middle plate together. This structure, through the fasteners, enhances the connection stability of the housing, the front panel assembly, and the middle plate.

[0011] Furthermore, a limiting plate is provided at the bottom of the back cover, and the surface of the limiting plate near the panel forms a limiting surface. In the above structure, the limiting surface can cooperate with the base of the cooking appliance, and the base is provided with upwardly extending ribs. The limiting surface can abut against the inner surface of the ribs, thereby preventing the lower end of the back cover from tilting outward and causing the panel to be pushed up, resulting in a gap between the panel and the outer shell. This increases the difficulty for water to enter the interior of the outer shell through the gap, ensuring the service life of the electronic components inside the panel assembly.

[0012] Furthermore, the housing assembly also includes a grounding plate disposed on the housing. This structure enhances the safety of the housing assembly and improves the user experience.

[0013] Furthermore, the grounding plate and the outer casing are either an integral structure or separate structures, and the grounding plate and the outer casing are made of the same material. This structure allows the grounding plate to be made from scrap materials from the outer casing manufacturing process, thereby reducing the production cost of the outer casing assembly.

[0014] Furthermore, the upper edge of the outer casing and / or the lower edge of the panel are rolled edges. In the above structure, the rolled edges can improve the strength of the outer casing and reduce the probability of deformation of the outer casing after long-term use.

[0015] Furthermore, the housing assembly also includes a middle plate having an upwardly extending first mounting groove, into which the upper edge of the housing is inserted. In the above structure, the first mounting groove can limit the housing and improve the connection stability between the middle plate and the housing.

[0016] According to another aspect of the present invention, a cooking appliance is provided, comprising: a shell assembly, the shell assembly described above; and an inner pot disposed within the shell assembly. In the above structure, since the shell assembly has the advantages of simple processing and high assembly efficiency, the cooking appliance having it also possesses the aforementioned advantages.

[0017] Furthermore, the cooking appliance also includes a base disposed at the lower edge of the outer shell of the outer shell assembly, wherein the base has a downwardly extending second mounting groove, into which the lower edge of the outer shell of the outer shell assembly is inserted. This structure is simple and can hold the outer shell between the first and second mounting grooves, thereby achieving a limiting effect on the outer shell. And / or, the base has an upwardly extending rib, the outer shell assembly is the aforementioned outer shell assembly, and the limiting surface of the outer shell assembly abuts against the inner surface of the rib. In the above structure, the limiting surface on the rear cover can abut against the inner surface of the rib, thereby preventing the lower end of the rear cover from warping outwards and causing the panel to lift, resulting in a gap between the panel and the outer shell. This increases the difficulty for water to enter the interior of the outer shell assembly through the gap, extending the service life of the cooking appliance.

[0018] Furthermore, the cooking appliance also includes: a heat-insulating cover, disposed between the outer shell assembly and the inner pot, the heat-insulating cover being equipped with a grounding device, and the grounding plate of the outer shell assembly being connected to the heat-insulating cover. In the above structure, the heat-insulating cover is equipped with a grounding device, and the grounding plate on the outer shell assembly is connected to the heat-insulating cover, allowing the outer shell assembly to be grounded through the grounding device on the heat-insulating cover. This prevents the user from touching the outer shell assembly and causing injury if the cooking appliance leaks electricity. The above structure improves the safety of the cooking appliance and enhances the user experience. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 4 and Figure 6 As shown, the housing assembly of this embodiment includes a housing 10 and a panel assembly 30. The housing 10 is formed by a plate, the two free ends of which are not connected to each other to form a mounting opening 1; the panel assembly 30 is disposed at the mounting opening 1 to connect the two free ends of the plate.

[0034] Applying the technical solution of this embodiment, when processing the outer shell 10, a plate of a predetermined length is cut, and then the plate is shaped into the required form of the outer shell 10. An installation opening 1 is directly formed between the two free ends of the plate. The panel assembly 30 is disposed at the installation opening 1, connecting the two free ends of the plate to form a whole outer shell assembly. Compared with the processing method mentioned in the prior art, this method reduces the following steps: first, it avoids connecting the plates into a ring; second, it avoids opening installation holes on the plate for mounting the panel assembly. Therefore, it reduces the processing steps of the outer shell assembly and improves the production efficiency of the outer shell assembly. Furthermore, since the length of the installation opening 1 needs to be removed when cutting the plate, the amount of material used in the plate can be reduced, thereby reducing the production cost of processing the outer shell 10.

[0035] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, the panel assembly 30 includes a panel 40 and a back cover 50 connected to each other. The panel 40 has multiple button areas, and the portions of the outer casing 10 located on both sides of the mounting opening 1 are sandwiched between the panel 40 and the back cover 50. In the above structure, the portions of the outer casing 10 located on both sides of the mounting opening 1 are sandwiched between the panel 40 and the back cover 50, allowing the outer casing 10 and the panel assembly 30 to be connected more tightly, forming a closed whole, thereby ensuring that the outer casing assembly has sufficient strength. It should be noted that in the above structure, electronic components such as a substrate 41 are disposed between the panel 40 and the back cover 50. The substrate 41 is connected to the back cover 50 by screws. Users can adjust the cooking appliance through the panel 40 to achieve various cooking methods. In addition, a mica sheet is also disposed between the substrate 41 and the back cover 50 to ensure the safety of the cooking appliance.

[0036] like Figure 1 , Figure 2 , Figures 4 to 7 As shown, in this embodiment, the rear cover 50 includes a rear cover body 51 and support plates 52 connected to both sides of the rear cover body 51. The support plates 52 are attached to the inner surface of the outer shell 10. In the above structure, the support plates 52 of the rear cover 50 are located inside the outer shell 10, the rear cover body 51 extends into the mounting opening 1, the panel 40 covers the outer side of the rear cover body 51, and the inner wall of the circumferential edge of the panel 40 abuts against the outer wall of the outer shell 10. When the rear cover 50 and the panel 40 are clamped together, the support plates 52 can apply an outward pushing force to the inner surface of the outer shell 10, and the inner wall of the panel 40 can apply an inward pushing force to the outer surface of the outer shell 10, thereby clamping the outer shell 10 between the panel 40 and the rear cover 50, so that the panel assembly 30 can be tightly connected to the outer shell 10. In addition, the attachment of the support plates 52 to the inner surface of the outer shell 10 can increase the area supporting the outer shell 10, further improving the strength of the outer shell assembly.

[0037] like Figures 1 to 3 As shown, in this embodiment, the outer casing assembly further includes a middle plate 60, which is disposed on the upper edge of the outer casing 10. The middle plate 60 includes a mounting plate 61, and the rear cover 50 is located between the mounting plate 61 and the front panel 40. Fasteners pass through the mounting plate 61, the rear cover 50, and the front panel 40 to connect the outer casing 10, the front panel assembly 30, and the middle plate 60 together. The above structure can limit and fix the top of the front panel assembly 30, so that the top of the front panel assembly 30 is firmly connected to the outer casing 10 and the middle plate 60, preventing the top of the front panel assembly 30 from flipping outward relative to the outer casing 10, and improving the reliability of the front panel assembly 30 installation. It should be noted that the rear cover 50 is provided with a first mounting hole 55, the front panel 40 is provided with a mounting post 42 opposite to the first mounting hole 55, the mounting post 42 is provided with a second mounting hole, and the mounting plate 61 is provided with a third mounting hole. The positions of the first mounting hole 55, the second mounting hole, and the third mounting hole are opposite to each other. During installation, the fastener is passed through the third mounting hole and the first mounting hole 55 from the inside out, and finally tightened into the second mounting hole of the mounting post, connecting the outer shell 10, the panel assembly 30, and the middle plate 60 together. The above structure, through the fastener, can improve the connection stability of the outer shell 10, the panel assembly 30, and the middle plate 60.

[0038] It should also be noted that, in this embodiment, a notch is provided on the lower edge of the middle plate 60, which is opposite to the mounting opening 1. There are two mounting plates 61, which are respectively disposed on the two opposite side walls of the notch.

[0039] like Figure 2 , Figure 5 and Figure 8 As shown, in this embodiment, a limiting plate 53 is provided at the bottom of the back cover 50, and a limiting surface 54 is formed on the surface of the limiting plate 53 near the panel 40. In the above structure, the limiting surface 54 can cooperate with the base of the cooking appliance. The base is provided with upwardly extending ribs, and the limiting surface 54 can abut against the inner surface of the ribs, thereby preventing the lower end of the back cover 50 from tilting outward and causing the panel 40 to be pushed up, thus preventing the phenomenon of gaps between the panel 40 and the outer shell 10 from occurring. This increases the difficulty for water to enter the interior of the outer shell 10 from the gaps, ensuring the service life of the electronic components inside the panel assembly 30.

[0040] like Figure 1 and Figure 4As shown, in this embodiment, the housing assembly further includes a grounding plate 70, which is disposed on the housing 10. In the above structure, since the housing 10 is made of metal, the grounding plate 70 can conduct the current carried on the housing 10 to the ground when the cooking appliance leaks electricity, thereby preventing the user from being injured when touching the housing 10. The above structure can improve the safety of the housing assembly and enhance the user experience.

[0041] like Figure 1 and Figure 4 As shown, in this embodiment, the grounding plate 70 and the outer casing 10 are an integral structure. This eliminates the need for a separate installation of the grounding plate 70, thereby improving the assembly efficiency of the outer casing assembly. Of course, in other embodiments not shown in the figures, the grounding plate 70 and the outer casing 10 can also be separate structures, and the grounding plate 70 and the outer casing 10 can be made of the same material. This structure allows the grounding plate 70 to be made from scrap materials from the outer casing 10 manufacturing process, thereby reducing the production cost of the outer casing assembly.

[0042] like Figure 1 and Figure 10 As shown, in this embodiment, the upper edge of the outer shell 10 and the lower edge of the plate are rolled edges 80. In the above structure, the rolled edges 80 can improve the strength of the outer shell 10 and reduce the probability of deformation of the outer shell 10 after long-term use. It should be noted that the rolled edges 80 can be arc-shaped rolled edges or folded edges, and both of these structures can improve the strength of the outer shell 10. Of course, in other embodiments not shown in the figure, rolled edges can be provided only on the upper edge of the outer shell 10 or only on the lower edge of the plate.

[0043] like Figure 1 and Figure 10 As shown, in this embodiment, the housing assembly further includes a middle plate 60, which has an upwardly extending first mounting groove 62, into which the upper edge of the housing 10 is inserted. In the above structure, the first mounting groove 62 can limit the housing 10, improving the connection stability between the middle plate 60 and the housing 10.

[0044] like Figure 9 and Figure 10 As shown, this application also provides a cooking appliance, which includes an outer shell assembly 120 and an inner pot 90. The outer shell assembly 120 is the aforementioned outer shell assembly; the inner pot 90 is disposed within the outer shell assembly 120. In the above structure, since the outer shell assembly 120 has the advantages of simple processing and high assembly efficiency, the cooking appliance having it also possesses the aforementioned advantages.

[0045] like Figure 1 , Figure 8 and Figure 10As shown, in this embodiment, the cooking appliance further includes a base 100, which is disposed at the lower edge of the outer shell 10 of the outer shell assembly 120. The base 100 has a downwardly extending second mounting groove 101, into which the lower edge of the outer shell 10 of the outer shell assembly 120 is inserted. In the above structure, the base 100 has a downwardly extending second mounting groove 101, and the middle plate 60 of the cooking appliance has an upwardly extending first mounting groove 62. The upper edge of the outer shell 10 can extend into the first mounting groove 62, and the lower edge of the outer shell 10 can extend into the second mounting groove 101. This structure is simple and can hold the outer shell 10 between the first mounting groove 62 and the second mounting groove 101, thereby achieving a limiting effect on the outer shell 10.

[0046] like Figure 2 and Figure 8 As shown, in this embodiment, the base 100 has an upwardly extending rib 102, and the outer shell assembly 120 is the aforementioned outer shell assembly 120. The limiting surface 54 of the outer shell assembly 120 abuts against the inner surface of the rib 102. In the above structure, the limiting surface 54 on the rear cover 50 can abut against the inner surface of the rib 102, thereby preventing the lower end of the rear cover 50 from tilting outward and lifting the panel 40, thus preventing a gap from forming between the panel 40 and the outer shell 10. This increases the difficulty for water to enter the interior of the outer shell assembly 120 through the gap, extending the service life of the cooking appliance. It should be noted that the second mounting groove 101 is formed by the rib 102 and the outer edge of the base 100.

[0047] like Figure 4 and Figure 9 As shown, in this embodiment, the cooking appliance further includes a heat-insulating cover 110, disposed between the outer shell assembly 120 and the inner pot 90. The heat-insulating cover 110 is equipped with a grounding device. The outer shell assembly 120 is the aforementioned outer shell assembly 120, and its grounding plate 70 is connected to the heat-insulating cover 110. In this structure, the heat-insulating cover 110 is equipped with a grounding device, and the grounding plate 70 on the outer shell assembly 120 is connected to the heat-insulating cover 110, allowing the outer shell assembly 120 to be grounded through the grounding device on the heat-insulating cover 110. This prevents injury to the user from touching the outer shell assembly 120 if the cooking appliance leaks electricity. This structure improves the safety of the cooking appliance and enhances the user experience.

[0048] It should be noted that during installation, first assemble the outer shell 10 with the panel assembly 30. After assembly, insert the upper edge of the outer shell 10 into the first mounting groove 62 of the middle plate 60. After installation, install the insulation cover 110 on the middle plate 60. After completing the above installation, connect the base 100. When connecting the base, ensure that the limiting surface 54 on the rear cover 50 abuts against the inner surface of the rib plate 102 on the base 100, then extend the lower edge of the outer shell 10 into the second mounting groove 101 of the base 100, and finally fix the base 100.

[0049] It should be noted that the cooking utensil also includes a lid 130, which is placed on the inner pot 90.

[0050] In this embodiment, the cooking appliance is an electric pressure cooker. Of course, in embodiments not shown in the figures, the cooking appliance can also be a rice cooker, a low-pressure rice cooker, a soy milk maker, a food processor, an electric slow cooker, a stir-fry machine, a multi-functional cooker, or other similar products.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
