Description

Technical Field

[0001] The present invention particularly relates to the technical field of chitin household appliances, and more particularly to a side control separable electric pressure cooker.

Background Art

[0002] An electric pressure cooker is a kitchen cooking appliance that combines the advantages of both a pressure cooker and an electric rice cooker. It is widely used in household cooking scenarios due to its high cooking efficiency, good texture of ingredients, and safe and convenient use.

[0003] In conventional electric pressure cookers, the pot body and the base are fixed, making separation difficult. As a result, the overall volume of the electric pressure cooker is large, making storage inconvenient. To facilitate use and storage, currently mainstream electric pressure cooker products on the market generally adopt a base-mounted structure. For example, in the utility model patent application with the patent application number CN201710755804.6 and the title "Separable Electric Pressure Cooker", an electric pressure cooker with such a base-mounted structure is disclosed, which allows the heating base and the pot body to be separated and stored individually. However, in the long-term use of such a structure of electric pressure cooker, some technical drawbacks that are difficult to solve have gradually become apparent. Specifically, they are as follows.

[0004] 1. The planar occupation space of the product is large, making it difficult to store in the kitchen. In the conventional structure, since the base needs to perform the function of supporting the pot body, the dimensions of the placement surface of the base must be not less than the bottom dimensions of the pot body. Regardless of the capacity of the pot body, the base requires an extra planar space equivalent to the pot body. At the same time, since all the heating, power supply, control components, etc. are integrated inside the base, the thickness and volume of the base are further increased, making it easy to occupy a large space during storage in the kitchen, and it is particularly difficult to adapt to the storage space of a narrow kitchen. Also, since the power supply and control components operate in a high-temperature environment for a long time, they are prone to damage.

[0005] 2. The heating plate is exposed, posing a safety hazard. Because the heating plate is located inside the base, there is a risk of burns or electric shock if the hot or live heating plate is touched when removing the pot.

[0006] 3. The pot body and base have poor compatibility, making it difficult to universally accommodate a variety of pot sizes. Although the base and pot body can be stored separately, the base is usually designed to correspond one-to-one with the pot body, resulting in low versatility. For example, a small base will only fit a corresponding small pot body and cannot stably support a large pot body. On the other hand, a large base can accommodate a small pot body, but this results in even more wasted space, and in this case, the heating area of ​​the base becomes larger than the bottom area of ​​the pot, which raises certain safety concerns.

[0007] Therefore, it is necessary to improve existing structures and provide a structural design for electric pressure cookers that is easier to store and offers superior safety and versatility. [Overview of the project] [Problems that the invention aims to solve]

[0008] In view of the above, this invention aims to provide a side-controlled, separate-type electric pressure cooker that solves, at least to some extent, the shortcomings of conventional base-mounted electric pressure cooker products, such as the large planar space required, making storage in kitchens difficult; the susceptibility of power supply and control components to damage in high-temperature environments; the presence of safety hazards such as burns and electric shocks; and the difficulty of universally adapting to various sizes of pots. [Means for solving the problem]

[0009] To achieve the above objective, this invention employs the following technical configuration.

[0010] A side-controlled, separate-type electric pressure cooker, A pot body component comprising a pot body and a heating base, wherein the heating base comprises a base shell, a heating component, and a first coupler, the base shell being fixed to the bottom of the pot body, the heating component being mounted within the base shell, and the first coupler being fixed to the base shell and electrically connected to the heating component. A lateral control component comprising a control assembly and a second coupler, wherein the second coupler is fixed to the outer wall of the control assembly and electrically connected to the control assembly, The first coupler and the second coupler are connected in a removable manner, and when plugged in, the circuit between them can be made conductive.

[0011] The beneficial effects achieved by this invention are as follows: In this invention, the heating component is integrated into the base, the lateral control component is provided as an independent module, and the first and second couplers enable rapid connection between the two. By housing the heating component and control components simultaneously inside the base, the problem of increased base volume, increased occupied space, and inability to fit into narrow storage spaces is solved. At the same time, by integrating the heating component and the pot body, safety hazards that would occur if the pot body and base were separated and the heating plate was exposed are avoided. Furthermore, because the lateral control component and the heating component are separated, the heating component is not affected by high temperatures for extended periods, extending its service life. In addition, the modular design of the lateral control component makes it compatible with a wide variety of electric pressure cooker bases, solving the problem of poor compatibility and low versatility of heating bases, and improving the versatility and flexibility of use of the product.

[0012] Furthermore, the control assembly includes an outer shell, an electrical control board, and an operating panel, wherein the electrical control board is fixed within the outer shell, the operating panel is fixed to an outer wall of the outer shell located away from the pot body and electrically connected to the electrical control board, and the second coupler is attached to a side wall of the outer shell located close to the pot body and electrically connected to the electrical control board.

[0013] The beneficial effects achieved by the above further configuration are as follows: By incorporating an electrical control board, damage due to collisions is effectively avoided. The control panel is separated from the pot body, making it easier to see and operate.

[0014] Furthermore, the outer shell includes a main shell and a cover plate, the main shell having a cover mounting opening on the side away from the pot body, the cover plate being attached to the cover mounting opening, the control panel being attached to the cover plate, and the second coupler being attached to the lower outer wall of the main shell, which is positioned close to the pot body.

[0015] The beneficial effects achieved by the above further configuration are as follows: By making the outer shell a fitting type with the main shell and cover plate, attachment and detachment become easier, and maintenance of the internal control components becomes possible.

[0016] Furthermore, a contact portion is provided on the upper outer wall of the main shell, which is positioned close to the pot body, and this contact portion is for contacting the outer surface of the pot body.

[0017] The beneficial effects achieved by the above further configuration are as follows: When the control assembly is connected to the pot body, the contact portion makes close contact with the surface of the pot body, further increasing the overall stability of the control assembly after it is connected to the pot body, and effectively preventing the control assembly from wobbling or tipping over.

[0018] Furthermore, the contact portion is a hemispherical projection.

[0019] The beneficial effects achieved by the above further configuration are as follows: By designing the contact portion in a hemispherical shape, the contact portion forms a point contact with the surface of the pot body, ensuring that the contact portion effectively contacts the pot body even if the side walls of the pot body have a certain degree of curvature or unevenness. This improves the reliability of the contact and its compatibility with various pot bodies.

[0020] Furthermore, the contact portion is made of a flexible material.

[0021] The beneficial effects achieved by the above further configuration are as follows: By using flexible material, scratches caused by hard contact between the contact area and the surface of the pot body are avoided, protecting the appearance of the pot body. At the same time, because the flexible material has a certain cushioning effect, it can further absorb vibrations transmitted to the control assembly and improve the stability of the connection.

[0022] Furthermore, when the first coupler and the second coupler are inserted, the bottom of the main shell and the bottom of the base shell become flush.

[0023] The beneficial effects achieved by the above further configuration are as follows: With this structure, when the control assembly and the pot body component are placed on the same plane, the bottoms of both are in close contact with the mounting surface, further enhancing the overall installation stability and preventing tilting due to the bottom of the control assembly lifting off the surface.

[0024] Furthermore, support blocks are provided at the bottom of the main shell and / or the base shell.

[0025] The beneficial effects achieved by the above further configuration are as follows. The support block avoids the direct contact and wear of the control assembly and / or the bottom of the pot body component with the installation surface, and also prevents water droplets and oil stains on the installation surface from directly contacting the bottom of the control assembly and / or the pot body component, thereby extending the service life.

[0026] Furthermore, a temperature sensor is further installed. The temperature sensor is mounted within the base shell, in close contact with the outer bottom wall of the pot body, and is electrically connected to the first coupler.

[0027] The beneficial effects achieved by the above further configuration are as follows. The temperature sensor is used to detect the temperature of the pot body in real time, facilitating the adjustment of the heating temperature by the control assembly.

[0028] Furthermore, a power cord is further installed. The power cord is electrically connected to the electric control board.

[0029] The beneficial effects achieved by the above further configuration are as follows. The power cord is used to energize and supply power to the electric control board from an external power source.

[0034] Referring to Figures 1 to 4, an embodiment of the present invention discloses a side-controlled, separated electric pressure cooker. This electric pressure cooker is, The pot body component 100 includes a pot body 110 and a heating base 120, the heating base 120 including a base shell 121, a heating component 122, and a first coupler 123, the base shell 121 being fixed to the bottom of the pot body 110 and having a sealing ring at the connection between the two to ensure airtightness, the heating component 122 being mounted inside the base shell 121 and in close contact with the bottom wall of the pot body 110, and the first coupler 123 being fixed to the base shell 121 and electrically connected to the heating component 122, A lateral control component 200 includes a control assembly 210 and a second coupler 220, wherein the second coupler 220 is fixed to the outer wall of the control assembly 210 and electrically connected to the control assembly 210. The first coupler 123 and the second coupler 220 are connected in a removable manner, and when plugged in, the circuit between them can be made conductive.

[0035] Specifically, referring to Figures 3 and 4, the control assembly 210 includes an outer shell 211, an electrical control board 212, and an operation panel 213. The electrical control board 212 is fixed inside the outer shell 211, and the operation panel 213 is fixed to the outer wall of the outer shell 211, which is located away from the pot body 110, and is electrically connected to the electrical control board 212. The second coupler 220 is attached to the side wall of the outer shell 211, which is located close to the pot body 110, and is electrically connected to the electrical control board 212. By incorporating the electrical control board 212, damage due to collision can be effectively avoided, and because the operation panel 213 is located away from the pot body, visibility and operation are made easier.

[0036] More specifically, the control panel 213 can be a touch-type or mechanical button-type control panel, and may include a power key for turning circuits on and off, and multiple function keys for implementing different cooking functions, allowing the user to operate it according to their needs.

[0037] Specifically, the outer shell 211 includes a main shell 2111 and a cover plate 2112, the main shell 2111 having a cover mounting opening on the side away from the pot body 110, the cover plate 2112 being mounted to the cover mounting opening, and the control panel 213 being mounted to the cover plate 2112. The second coupler 220 is mounted to the lower outer wall of the main shell 2111, which is located close to the pot body 110. The cover plate 2112 is secured to the cover mounting opening by connection methods such as bolts, adhesive, or snap-fit, and a sealing ring or sealant may be provided between the cover mounting opening and the cover plate 2112 for sealing purposes to protect the internal control components.

[0038] Specifically, the main shell 2111 has a roughly L-shaped structure, which increases the contact area between its bottom and the mounting surface, allowing it to be stably placed on the mounting surface.

[0039] Specifically, the cover plate 2112 may be positioned at an angle, with its top edge inclined toward the pot body 110, and the control panel 213 positioned parallel to the cover plate 2112. This upward inclination of the cover plate 2112 ensures that the control panel 213 faces the user, making it easy to see and operate, even when the mounting surface is at a low position. To understand this, depending on the height of the mounting surface, the cover plate 2112 and the control panel 213 can also be positioned vertically or inclined downward (i.e., with the bottom edge inclined toward the pot body 110).

[0040] Specifically, referring to Figures 3 and 4, a contact portion 2113 is provided on the upper outer wall of the main shell 2111, which is positioned close to the pot body 110. The contact portion 2113 is for contacting the outer surface of the pot body 110. When the lateral control component 200 is connected to the pot body 110, the contact portion 2113 makes close contact with the surface of the pot body 110, further enhancing the overall stability after connection and effectively preventing the lateral control component 200 from wobbling or tipping over.

[0041] Specifically, the contact portion 2113 is a hemispherical projection. By designing the contact portion 2113 to be hemispherical, the contact portion 2113 forms a point contact with the surface of the pot body 110, ensuring that the contact portion 2113 effectively contacts the pot body 110 even if the side walls of the pot body 110 have a certain degree of curvature or unevenness. This improves the reliability of the contact and its compatibility with various pot bodies 110.

[0042] Specifically, the contact portion 2113 is made of a flexible material. By using a flexible material, scratches caused by hard contact between the contact portion 2113 and the surface of the pot body 110 are avoided, protecting the appearance of the pot body 110. At the same time, because the flexible material has a certain cushioning effect, it can further absorb vibrations transmitted to the control assembly 210, thereby improving the stability of the connection.

[0043] Specifically, when the first coupler 123 and the second coupler 220 are inserted, the bottom of the main shell 2111 and the bottom of the base shell 121 become flush. This structure ensures that when the control assembly 210 and the pot body component 100 are placed on the same plane, the bottoms of both are in close contact with the mounting surface, further enhancing overall installation stability and preventing tilting caused by the bottom of the control assembly 210 lifting off the ground.

[0044] Specifically, multiple support blocks 2114 are evenly distributed at the bottom of the main shell 2111 and / or base shell 121, enabling close contact with the mounting surface via the support blocks 2114. The support blocks 2114 prevent the bottom of the control assembly 210 and / or pot body component 100 from wearing down due to direct contact with the mounting surface, and also prevent water droplets and oil stains on the mounting surface from directly contacting the bottom of the control assembly 210 and / or pot body component 100, thereby extending the service life. To understand this, when support blocks 2114 are provided at the bottom of the main shell 2111 and / or base shell 121, it is necessary to ensure that the support blocks can make close contact with the mounting surface when the first coupler 123 and the second coupler 220 are inserted.

[0045] Specifically, the support block 2114 is detachably connected to the bottom of the main shell 2111 and / or the base shell 121. Here, the detachable connection type includes at least one of the following connection types: snap-fit ​​connection, screw connection, magnetic adsorption connection, etc.

[0046] Specifically, the heating component 122 includes a heating tube 1221 and a heat conduction plate 1222. The heat conduction plate 1222 is fixed to the outer bottom wall of the pot body 110 and is in close contact with the bottom wall of the pot body 110, and the heating tube 1221 is fixed to the underside of the heat conduction plate 1222. The heating tube 1221 may be connected to the bottom of the heat conduction plate 1222 by brazing, but it may also be connected by other suitable methods. The heat conduction plate 1222 may be connected to the bottom of the pot body 110 by brazing, but it may also be connected by other suitable methods.

[0047] Specifically, a temperature sensor 124 is also installed. The temperature sensor 124 is mounted inside the base shell 121, and its detection end penetrates a relief hole in the center of the heat conduction plate 1222, making close contact with the outer bottom wall of the pot body 110, and is electrically connected to the first coupler 123. The temperature sensor 124 is used to detect the temperature of the pot body 110 in real time, and the detected temperature signal is fed back to the electrical control board 212 to adjust the heating temperature. In a pressure cooker, the pressure is higher with higher temperatures, so the pressure inside the pot can be monitored simply by monitoring the heating temperature, and there is no need to provide a separate pressure monitoring element.

[0048] Specifically, a fuse 125 is further installed inside the base shell 121. The fuse 125 is connected to the electrical circuit of the heating element 1221 and blows if the temperature rises abnormally and exceeds a safety threshold, thus providing a safety protection function to prevent the temperature and pressure inside the pot from becoming uncontrollable.

[0049] Specifically, a power cord 230 is also installed, and the power cord 230 is electrically connected to the electrical control board 212. Power can be supplied by supplying power to an external power source using the power cord 230.

[0050] Specifically, the pot body 110 provided by this invention may be a regular electric heating pot body or a pressure cooker pot body, and a corresponding pot lid component 300 can be attached to the top of the pot body 110 for use.

[0051] The method of using the side-controlled, separate-type electric pressure cooker of this embodiment is as follows:

[0052] When using the product, first the pan body component 100 is placed stably on a kitchen counter or table, and then the lateral control component 200 is placed on one side of the pan body component 100. After that, the second coupler 220 of the lateral control component 200 is inserted into the first coupler 123 on the side wall of the base shell 121 to achieve electrical connection between the two. At this time, the contact portion 2113 of the main shell 2111 contacts the side wall of the pan body component 100, further fixing their relative positions. After they are relatively fixed, the height of the bottom support block 2114 can be adjusted to ensure that both the pan body component 100 and the control assembly 210 make stable contact with the kitchen counter or table.

[0053] When the corresponding cooking parameter is selected using the function keys on the control panel 213 and the power key is pressed to start the device, the heating component 122 activates and heats the pot body 110. During heating, the temperature sensor 124 detects the temperature of the pot body 110 in real time and quickly feeds it back to the control assembly. The control assembly controls the power supply and cut-off of the heating component 122 via a smart switch, thereby adjusting the heating temperature.

[0054] When storing, the pot body component 100 and the lateral control component 200 can be separated and stored simply by removing the second coupler 220 from the first coupler 123. Alternatively, the lateral control component 200 can be placed directly inside the pot body 110 and stored together with the entire pot body component 100, significantly saving storage space. At the same time, a single lateral control component 200 can be fitted to multiple pot body components 100 of the same type and with matching electrical parameters of different capacities, allowing users to swap out the corresponding pot body component 100 according to their cooking needs without having to prepare multiple lateral control components 200 separately.

[0055] The side-control separated electric pressure cooker of this embodiment adopts a modular design, achieving separation of the side control component 200 and the pot body component 100. This not only makes it safer to use and easier to store, but also effectively prevents the control assembly 210 from suffering long-term high-temperature damage, extending its service life. At the same time, the same side control component 200 can be fitted to multiple pot body components 100 of the same type and with matching electrical parameters, improving the versatility and flexibility of use of the product.

[0056] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be realized in other embodiments without departing from the spirit or scope of the present invention. Accordingly, the present invention is not limited to these embodiments shown herein, but is applicable to the broadest scope that is consistent with the principles and novel features disclosed herein.
