Description

Technical Field

[0001] This invention relates to the field of kitchenware, and more specifically to a modular kitchenware. Background Technology

[0002] A modular kitchen appliance mainly consists of a base and a container. The container can be used to add water or oil and is equipped with a heating system to heat the container for cooking.

[0003] Heating systems in split-type kitchen appliances can use either electric heating elements or heating coatings, both of which suffer from uneven heating. When using electric heating elements, the heating path of the element itself results in higher temperatures along this path compared to areas with lower temperatures, leading to uneven heating. Furthermore, the high thermal inertia of electric heating elements makes it difficult to control temperature changes promptly. When using heating coatings, the coating area on the container avoids the electrical connection structures on the base. Incomplete coating application results in higher temperatures in the coated areas and lower temperatures in the areas with electrical connections, also causing uneven heating.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0012] A further technical solution is that the second part is a connector assembly, including a terminal block, and the first part is a socket assembly, including a spring contact for contacting the terminal block.

[0013] A further technical solution is that the connector assembly further includes: a fixing frame, fixed to the container body; an electrode, which is an elastic conductive material, fixed to the first end of the terminal post; wherein, the second end of the terminal post passes through and extends out of the fixing frame, and the fixing frame squeezes the electrode and deforms at least a portion of the electrode so that the electrode contacts the conductive interface.

[0014] A further technical solution is that the plug-in assembly further includes: a fixed base, fixed to the base; and a support spring; wherein: the first end of the spring is fixed to the fixed base and used to connect to an external power source, and the second end of the spring is fixed to the fixed base by the support spring and used to contact the terminal block.

[0017] The beneficial effects of the embodiments of the present invention are as follows:

[0018] (I) The split-type kitchen appliance disclosed in the embodiments of the present invention has a heating coating on the outside of the container body. The conductive interface extends from the bottom coating to the side of the pot body and is electrically connected to the second part of the electrical connection component disposed on the side of the container body. The first part of the electrical connection component is disposed on the base. When the container body is placed on the base, the first part and the second part of the electrical connection component are electrically connected. The heating coating is energized and heated, which can ensure that the entire bottom coating is heated evenly. The electrical connection component does not affect the uniformity and integrity of the entire heating coating, and can achieve uniform heating of the entire container body.

[0019] The heating coating is applied by spraying, and the preferred shape is a rounded rectangle, which is easy to process, has a large heating area, and provides uniform heating.

When the container is placed on the base, the post pushes the sliding plate open, making contact with the contact spring, and the conductive coating heats up when energized. When the container is lifted off the base, the post rises, and the return spring pushes the sliding plate back to cover the contact spring, protecting it from exposure. During use, the sliding plate does not obstruct the electrical connection; when not in use, it prevents the contact spring from being contaminated and oxidized. Attached Figure Description

[0033] First embodiment:

[0034] The first embodiment discloses a split-type kitchen appliance. Figure 1 An isometric view of the split-type kitchen appliance provided in the first embodiment of the present invention is shown. Figure 2 An isometric view of the container body 1 in the split kitchen appliance provided in the first embodiment of the present invention is shown. Figure 3 An isometric view of the base 4 in the split kitchen appliance provided in the first embodiment of the present invention is shown. Figure 4An isometric view of the container body 1 in the split kitchen appliance provided in the first embodiment of the present invention is shown from another perspective. Figure 5 An exploded structural diagram of the container body 1 in the split-type kitchen appliance provided in the first embodiment of the present invention is shown.

[0035] For example, a detachable kitchen appliance is a detachable electric hot pot. Existing electric hot pots generally include functions such as steaming, boiling, frying, and deep-frying. They mainly consist of a base, a pot body, a steamer basket, and a lid. Water or oil is added to the pot body, and the heating system heats the pot body to cook various delicious foods. Those skilled in the art will understand that the technical solution disclosed herein can also be applied to other types of detachable heatable kitchen appliances, such as detachable electric frying pans, detachable electric steamers, and detachable electric kettles.

[0036] like Figures 1-5 As shown, the modular cookware includes a container body 1, a heating coating 3, a base 4, and an electrical connection assembly. It may also include a lid 6 covering the container body 1. The container body 1 is placed on the base 4, and the heating coating 3, being a conductive material, is coated on the outside of the container body 1. When the modular cookware is an electric hot pot, the container body 1 is the pot body. The heating coating 3 includes a bottom coating 32 and a conductive interface 31. The bottom coating 32 is coated on the bottom surface of the container body 1, and the conductive interface 31 is coated on the side surface of the container body 1 and communicates with the bottom coating 32, bypassing the connection between the bottom and side surfaces. For example, the heating coating 3 is formed by spraying a conductive paste.

[0037] The electrical connection assembly includes a first part and a second part. The first part is mounted on the base 4. The second part is mounted on the side of the container body 1 and electrically connected to the conductive interface 31 for electrical connection with the first part. In this embodiment, when the container body 1 is placed on the base 4, the first part and the second part are electrically connected, and the heating coating 3 is energized to generate heat, heating the container body 1 and the contents inside the container body 1. Furthermore, the electrical connection assembly is mounted on the side of the container body 1, which does not affect the integrity of the bottom coating 32 of the container body 1, thus improving the uniformity of heating of the split-type kitchen appliance.

[0038] In the embodiments of this disclosure, electrical connection can be understood as the form in which different components in the circuit structure are connected by physical lines that can transmit electrical signals, such as PCB copper foil or wires.

[0039] like Figure 3 As shown, the base 4 further includes a protrusion 42 located on one side of the container body 1 placement position for mounting the first part. This ensures that the bottom coating 32 on the bottom surface of the container body 1 is fully coated without affecting the proper connection of the electrical connection components.

[0040] like Figure 5 As shown, the container body 1 further includes a baffle 12, which is fixed to the outside of the bottom coating 32 to protect the bottom coating 32.

[0041] The container body 1 further includes a raised edge 16, which is disposed around the bottom coating 32 on the bottom surface of the container body 1 and between the baffle 12 and the bottom surface of the container body 1, such that the baffle 12 is fixed at a certain distance from the surface of the bottom coating 32. This does not affect the heating of the bottom coating 32. The raised edge 16 is provided with a raised edge notch, which is located on the coating path of the conductive interface 31 and does not affect the coating of the conductive interface 31. The conductive interface 31 passes through the raised edge notch and the connection between the bottom surface and the side surface of the container body 1, and is coated on the side surface of the container body 1.

[0042] The base 4 further includes a first positioning structure, and the container 1 further includes a second positioning structure. The second positioning structure matches the first positioning structure and positions the container 1 in a fixed position on the base 4, preventing the container 1 from shaking. Figures 3-5 As shown, exemplarily, the second positioning structure is a support foot 11. The first positioning structure is a positioning groove 41. Specifically, a fixing post 17 is provided at the bottom of the container body 1, and the support foot 11 is connected to the fixing post 17 by a connecting structure such as screws, and presses the baffle 12 and the container body 1 together. When the container body 1 is placed on the base 4, the support foot 11 is engaged in the positioning groove 41.

[0043] Second embodiment:

[0044] Based on the first embodiment, the second embodiment further optimizes and refines the conductive connection structure in the first embodiment.

[0045] Figure 6 It shows Figure 5 A magnified structural diagram at point A. Figure 7 An isometric view of the plug-in assembly 5 in the split kitchen appliance provided in the second embodiment of the present invention is shown. Figure 8 An exploded view of the connector assembly 5 in a split-type kitchen appliance according to a second embodiment of the present invention is shown. Figures 1 to 8 As shown, the second part is the connector assembly 2, including the terminal 22. The first part is the socket assembly 5, including the spring 55, for contacting the terminal 22. The terminal 22 is electrically connected to the conductive interface 31. The spring 55 is electrically connected to an external power source. When the terminal 22 contacts the spring 55, the first and second parts are electrically connected, and the heating coating 3 is energized and heats up.

[0046] For example, the connector assembly 5 is disposed on the protrusion 42 on the side of the base 4. The connector assembly 2 is provided with two terminals 22, and the connector assembly 5 is provided with three spring contacts 55. When the container body 1 is placed on the base 4, the terminals 22 press down to contact the spring contacts 55, and the first part and the second part are electrically connected, and the heating coating 3 is energized and heated.

[0047] like Figure 5 , Figure 6 As shown, the connector assembly 2 further includes a mounting bracket 21 and an electrode 23. Exemplarily, a platform 15 with a vertical plane may be provided on the side of the container body 1, and the mounting bracket 21 is fixed to the side of the container body 1, i.e., the vertical plane of the platform 15. The electrode 23 is made of an elastic conductive material, exemplarily such as metal, and is fixed to the first end of the terminal 22. The second end of the terminal 22 passes through and extends out of the mounting bracket 21, which compresses the electrode 23 and deforms at least a portion of the electrode 23 so that the electrode 23 contacts the conductive interface 31, allowing the heating coating 3 to be powered and heated.

[0048] like Figure 6 As shown, exemplarily, electrode 23 includes an integrally formed connecting portion 231 and a bent portion 232. The connecting portion 231 is fixed to the first end of the terminal 22. The bent portion 232 is used to contact the conductive interface 31. Electrode 23 forms two planar structures and an inclined structure for connecting the two planar structures. The included angle between the planar structures and the inclined structure is an obtuse angle, which results in a large contact area and stable current conduction. Of course, in other embodiments, electrode 23 can also be other shapes, such as spring type, circular, hook type, etc., as long as electrode 23 can be compressed to produce elastic deformation and contact the conductive interface 31, the present invention does not impose further limitations on this.

[0049] like Figure 6 As shown, exemplarily, the terminal 22 includes a first post 221 and a second post 222. The second post 222 fixes the electrode 23 by molding. The outer diameter of the second post 222 is larger than the outer diameter of the first post 221. Specifically, the mounting bracket 21 has a first hole 211 through which the first post 221 passes, and the second post 222 abuts against the first hole 211, facilitating the mounting bracket 21 to compress the terminal 22 and the electrode 23.

[0050] like Figure 7 , Figure 8 As shown, the connector assembly 5 further includes a fixed base 51 and a support spring 53. The fixed base 51 is fixed to the base 4. The first end of the spring 55 is fixed to the fixed base 51 and is used to connect to an external power source, such as connecting to the live wire, neutral wire, and ground wire of the external power source respectively. The second end of the spring 55 is fixed to the fixed base 51 by the support spring 53 and is used to contact the terminal 22. A first opening 421 can be provided on the base 4. When the container 1 is placed on the base 4, the terminal 22 is pressed down through the first opening 421 to contact the spring 55. The support spring 53 provides an upward elastic force to ensure that the terminal 22 and the spring 55 are in tight contact.

[0051] The connector assembly 5 further includes a slide plate 52 and a return spring 54. The slide plate 52 is slidably mounted on the fixed base 51 and located above the spring contacts 55. The slide plate 52 includes second openings 522 for exposing the spring contacts 55, the number of which is the same as the number of spring contacts 55. In this embodiment, there are three spring contacts 55, so there are also three second openings 522. A ramp 521 is provided on the side edge of at least one of the second openings 522. For example, the ramp 521 is provided on the side of one of the middle second openings 522. The ramp 521 is used to withstand the downward force of the terminal 22 and convert the downward force into a horizontal force, thereby pushing the slide plate 52 open.

[0052] The return spring 54 is connected between the fixed base 51 and the slide plate 52. The direction of the force storage of the return spring 54 is parallel to the direction of the sliding of the slide plate 52. When the return spring 54 stores force, the second opening 522 exposes the spring piece 55. When the return spring 54 releases force, the slide plate 52 covers the spring piece 55.

[0053] With the sliding plate 52 and return spring 54 installed, when the container 1 is placed on the base 4, the terminal 22 passes through the first opening 421 and presses down on the inclined surface 521. The inclined surface 521 converts the downward force into a horizontal force, pushing the sliding plate 52 open. The position of the second opening 522 aligns with the position of the spring piece 55, exposing the spring piece 55. The terminal 22 contacts the spring piece 55, and the heating coating 3 is energized and heats up. When the container 1 is lifted off the base 4, the terminal 22 is lifted upward, and the return spring 54 pushes the sliding plate 52 back to cover the spring piece 55, protecting the spring piece 55 from exposure and preventing contamination and oxidation when not in use.

[0054] Furthermore, such as Figure 2 As shown, the connector assembly 2 also includes a sealing ring 24, which is fitted onto the fixing frame 21, specifically at the connection between the fixing frame 21 and the container body 1. The sealing ring 24 has a third hole 241 through which the electrode 23 passes. The sealing ring 24 serves to waterproof the connector assembly 2. The third hole 241 is larger than the contact area between the electrode 23 and the conductive interface 31, facilitating the deformation of the electrode 23.

[0055] like Figure 2 As shown, the fixing bracket 21 is further provided with a guide block 213 for the terminal 22 to pass through, and the guide block 213 is used to ensure that the extension direction of the terminal 22 does not deviate.

[0056] Please refer to Figure 2 , Figure 4Furthermore, a grounding post 13 is provided on the side of the container body 1. One end of the grounding post 13 contacts the container body 1, and the other end is flush with the terminal post 22, passing through the fixing frame 21 and the sealing ring 24, for connecting the ground wire to ground the container body 1, and at the same time serving to position the connector assembly 2. Specifically, a second hole 212 is opened in the center of the fixing frame 21 for the grounding post 13 to pass through.

[0057] The installation process of the structure shown in the second embodiment is as follows: Pass the terminal 22 through the fixing frame 21, put the sealing ring 24 on the outside of the fixing frame 21, so that the electrode 23 is exposed through the third hole 241 of the sealing ring 24, pass the grounding post 13 through the sealing ring 24 and the fixing frame 21, and connect the fixing lug 214 of the fixing frame 21 to the stud 14 of the container body 1 with screws. Then the fixing frame 21 is pressed towards the container body 1, so that the bent part 232 of the electrode 23 is deformed and makes tight contact with the conductive interface 31, thus completing the installation of the connector assembly 2.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.

[0060] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. The present invention can be modified in any form without departing from its basic structure.
