Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

The utility model provides a kind of deep pot body subassembly and cooking utensil. The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 shows a cooking appliance 1 according to a preferred embodiment of the present invention, which includes a pot body assembly 10 and a lid 20. According to the utility model discloses a cooking utensil can be for electric rice cooker, electric pressure cooker or other cooking utensil, and according to the utility model discloses a cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee, a kind of deep pot hot water, fried dish.

The pot body assembly 10 includes at least a pot body housing 11 and an inner pot 12. Wherein, the cooker body shell 11 is approximately in the shape of a round-corner cuboid. The inner pot 12 is provided in the pot body housing 11 for providing a space required for cooking. For example, a straight cylindrical inner pot housing portion may be provided in the pot body housing 11. The inner pot 12 can be freely put into or taken out of the inner pot receiving part to facilitate cleaning thereof. Of course, other components related to the cooking function, such as a power supply board or a heating device, etc. (not shown) can be arranged in the cooker body assembly 10.

The lid body 20 is openably and closably provided with respect to the pot body assembly 10. The lid 20 therefore generally has a shape that conforms to the shape of the pot assembly 10. In the present embodiment, the lid body 20 may be connected to the pot body assembly 10 by a pivot shaft (not shown), and opened and closed with respect to the pot body assembly 10 in a manner of pivoting about the pivot shaft. When the cover 20 is opened with respect to the pot body assembly 10, the opening of the inner pot 12 in the pot body assembly 10 is exposed, and a user can add ingredients to the inner pot 12 or take cooked food out of the inner pot 12. When the cover 20 is closed over the pot body assembly 10, it covers the inner pot 12 and forms a cooking space with the inner pot 12 (see fig. 2). A sealing ring (not shown) is provided between the cover 20 and the inner pot 12 to maintain a good sealing property of the cooking space.

Further, the pot body assembly 10 further includes an outer pot 32 as shown in fig. 2 to 5. The outer pot 32 is disposed in the pot body housing 11, and has a bottom wall 321 and a side wall 322. The bottom wall 321 extends generally transversely. The side wall 322 extends upward from the edge of the bottom wall 321 and surrounds the circumference. Thereby, a receiving space is formed between the bottom wall 321 and the side wall 322, and the heating means (e.g., the heat generating plate) and the inner pot 12 are enclosed therein in a direction from below to above. In other words, the outer pot 32 isolates the inner pot 12 and the heating means from other components from below and from the sides. Therefore, heat exchange between the heating device and the inner pot 12 during cooking and the outside can be reduced, the heat preservation and insulation effects are achieved, and the heating efficiency of the inner pot 12 can be improved.

In addition, the pot body assembly 10 further includes a temperature limiter 33. The temperature limiter 33 may be, for example, a magnetic steel temperature limiter or the like. The temperature limiter 33 is mainly used for sensing the temperature of the inner pot 12, and when the temperature of the inner pot 12 reaches a predetermined value, the power supply circuit of the heating device is disconnected, so that the heating is stopped, the temperature of the inner pot 12 is prevented from being continuously increased, and the effect of safety protection is achieved.

As shown in FIG. 2, the temperature limiter 33 includes a sensing end 331 and a mounting end 332. In the assembled state, the sensing end 331 may abut against the bottom wall of the inner pot 12 to sense the temperature of the inner pot 12. The mounting end 332 is provided with a catch 334. In addition, the temperature limiter 33 includes a lever 333 to control the operation of the temperature limiter. Rod 333 is telescopically passable from mounting end 332 and extends outwardly from mounting end 332. According to the utility model discloses, the mode that installation end 332 hooked outer pot 32 through card foot 334 realizes that the installation is fixed.

Specifically, the bottom wall 321 of the outer pot 32 is provided with a through central hole 323 and a side hole 324. The temperature limiter 33 is disposed inside the outer pot 32 with a rod 333 passing through the central hole 323 to be connected with a lever or the like for controlling its operation. The catch 334 passes through the side hole 324 and hooks at the edge of the side hole 324. Further, the pot body assembly 10 further includes an elastic member 34 which applies an elastic force from the mounting end 332 toward the sensing end 331 to the temperature limiter 33 so that the catch 334 is always kept in close contact with the edge of the side hole 324, thereby preventing the hooking connection from failing. Thus, the temperature limiter 33 remains fixed relative to the outer pot 32 in a vertical direction defined between the sensing end 331 and the mounting end 332.

In the illustrated embodiment, the elastic member 34 is configured as a spring. Thus, the elastic member 34 may also be referred to as a spring 34. When installed, the temperature limiter 33 is nested within the spring 34. The first end 341 of the spring 34 abuts against the temperature limiter 33 and the second end 342 abuts against the inner side of the bottom wall 321 of the outer pot 32. In a state where the temperature limiter 33 is mounted in place, the spring 34 is compressed to apply an elastic force to the temperature limiter 33. Preferably, the temperature limiter 33 is provided with a positioning rib 337 protruding laterally outward at a position close to the sensing end 331. The first end 341 of the spring 34 exerts a resilient force on the temperature limiter 33 by abutting against the positioning rib 337.

Preferably, the spring 34 is configured to gradually increase in radial dimension thereof in a vertical direction from the sensing end 331 toward the mounting end 332 (i.e., from the first end 341 toward the second end 342). Thus, the spring 34 can maintain a space from the side of the temperature limiter 33. Therefore, the spring 34 does not hinder the vertical movement of the temperature limiter 33 relative to the outer pot 32, and the movement thereof is prevented from being insensitive.

It is understood that in other embodiments, the spring 34 may also exert a spring force on the temperature limiter 33 in a manner that is stretched. Alternatively, the elastic member 34 may be configured in other manners than a spring, such as a silicone member or a rubber member.

In order to stabilize the temperature limiter 33, it is understood that the catches 334 are provided in at least two and are spaced around the rod 333. Correspondingly, the side holes 324 are provided in at least two and are spaced around the central hole 323. Preferably, the catch 334 and the side hole 324 may be provided in the same number and in a one-to-one correspondence. As shown in fig. 2, the catch 334 and the side hole 324 are provided in two. However, in other embodiments, the number of side holes 324 may be greater than the number of catches 334, for example, the number of side holes 324 may be twice or more the number of catches 334, thereby allowing different mounting angles for the temperature limiter 33, increasing flexibility in mounting the temperature limiter 33.

Referring to fig. 4, in the present embodiment, the temperature limiter 33 has an outer case 338. The catch 334 is formed by stamping the housing 338 and includes an extension 335 and a hook 336. Wherein the extension 335 extends vertically outward from the mounting end 332. The hooking portion 336 extends in the lateral direction from the tip of the extending portion 335, and is formed in a substantially L-shape with the extending portion 335. Of course, the hooking portions 336 may also extend laterally from the ends of the extension portions 335 toward opposite directions, so that both are formed in a substantially T-shape. The side holes 324 are generally configured as elongated holes and are slightly arcuate. The temperature limiter 33 allows the hook portion 336 to be hooked at the edge of the side hole 324 in such a manner that the catch 334 passes through the corresponding side hole 324 and rotates.

During installation, the spring 34 is first placed over the temperature limiter 33. The mounting end 332 of the temperature limiter 33 is then moved toward the bottom wall 321 inside the outer pot 32 such that the rod 333 passes through the central hole 323 and the catches 334 pass through the respective corresponding side holes 324, as shown in fig. 3. At this time, the spring 34 is in a compressed state. In order to facilitate the passage of the catch 334, as shown in fig. 2, the side hole 324 is provided with a notch portion 325 such that the size thereof at the notch portion 325 is larger than the lateral size of the hook portion 336 of the catch 334.

After the rod member 333 and the catch 334 pass through the respective holes, the temperature limiter 33 is rotated to the position shown in fig. 4 centering on the rod member 333. At this time, the extension 335 of the catch 334 abuts against the edge of the side hole 324. When the temperature limiter 33 loses the action of the external force, it will move away from the bottom wall 321 of the outer pot 32 under the elastic force of the spring 34, and finally the hooking part 336 of the catch 334 is hooked on the edge of the side hole 324 (i.e. the outer side surface of the bottom wall 321). At this time, the temperature limiter 33 and the outer pot 32 are kept relatively fixed in the vertical direction.

Further, as shown in fig. 2, a limiting rib 326 is further disposed at an edge of at least one side hole 324. The retention rib 326 may be formed by, for example, stamping. Before the temperature limiter 33 is installed, the limiting rib 326 extends away from the side hole 324 to avoid obstructing movement of the catch 334 within the side hole 324. As shown in fig. 4 and 5, after the clip 334 of the temperature limiter 33 is hooked on the side hole 324, the limiting rib 326 may be moved toward the side hole 324 in a bending manner to a moving path of the clip 334 in the side hole 324. The edges of the limiting ribs 326 and the side holes 324 clamp the extension 335 of the catch 334 therein. Under the above-described structure, the at least one catch 334 remains fixed laterally with respect to the lateral hole 324. That is, the temperature limiter 33 and the outer pot 32 are kept fixed in the lateral direction. This realizes the attachment and fixation of the temperature limiter 33.

According to the utility model discloses, the mode that the temperature limiter is hung on outer pot through the card foot hook of self realizes that the installation is fixed to the elastic component can increase the firm degree of installation. The fixing mode can omit a fixing device such as an outer cup cover and a connecting piece such as a screw, so that the required materials are reduced, and the material cost can be reduced. And the installation process is simple to operate, and the operation steps of fixing the outer cup cover, screwing the screw and the like can be omitted, so that the production efficiency is improved, and the labor cost is reduced.
