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 (not shown) and the like, can also 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 a heat generating plate 31 and an outer pot 32 as shown in fig. 2 and 3. The heating plate 31 and the outer pot 32 are both provided in the pot body housing 11. Wherein, the heating plate 31 is positioned below the inner pan 12 and is directly or indirectly contacted with the bottom surface of the inner pan 12 for heating the inner pan 12.

As shown in fig. 2 and 3, the outer pot 32 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 heat generating plate 31 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 plate 31 from other components from below and from the side. Therefore, heat exchange between the heating plate 31 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.

It is understood that, in the above-described structure, at least the main body portion of the heat generating plate 31 for generating heat is disposed inside the outer pot 32, and the heat generating plate 31, such as the terminal and the clamping structure, protrudes to the outside of the outer pot 32 through the bottom wall 321 of the outer pot 32.

In addition, the pot body assembly 10 further comprises a thermostat 33 for sensing the temperature of the heating plate 31 and controlling the heating plate 31 to stop heating when the temperature thereof exceeds a predetermined standard, thereby performing a safety protection function. According to the utility model discloses, temperature controller 33 directly fixes on outer pot 32, and it indirectly judges the temperature of dish 31 that generates heat through the temperature of sensing outer pot 32. The direct fixing mode can omit parts such as a fastener and a bracket which are specially used for fixing the temperature controller 33, can simplify the assembly process, improve the production efficiency, and reduce the production cost in the aspects of labor, time, materials and the like.

Specifically, as shown in fig. 3, the thermostat 33 is generally configured as a cylindrical structure having a sensing end 331 and an electrical connection end 332 at both ends of the cylindrical structure. The thermostat 33 is fixed to the outside of the bottom wall 321 of the outer pot 32, and the sensing end 331 thereof abuts on the bottom wall 321, indirectly sensing the temperature of the heating plate 31 through the outer pot 32. In order to ensure the accuracy of temperature measurement, it is preferable that the heating plate 31 abuts against the inner side surface of the bottom wall 321 of the outer pot 32 to ensure good heat conduction efficiency between the heating plate 31 and the sensing end 331, so that the outer pot 32 can correctly reflect the real temperature level of the heating plate 31.

The electrical connection terminal 332 may be connected to a power supply circuit of the heat generating plate 31. For example, it may be connected in series to the power supply circuit of the heat generating plate 31. It is understood that when the temperature of the hot plate 31 exceeds a predetermined level, parts adjacent to the hot plate 31 are easily damaged by overheating, and even a fire may be caused. Therefore, when the temperature sensed by the thermostat 33 through the sensing terminal 331 exceeds a predetermined level, it can be automatically switched to an off state, so that the power supply circuit of the heat generating tray 31 is turned off, and heating is stopped, so as to prevent the temperature of the heat generating tray 31 from continuously rising. When the sensed temperature is lower than the allowable value, the thermostat 33 may be switched to the on state again, and the heating plate 31 may be turned on to heat.

In order to fix the thermostat 33 on the outer pot 32, as shown in fig. 3, the outer side surface of the bottom wall 321 of the outer pot 32 is provided with a fixing rib 323 and a receiving groove 325. The fixing ribs 323 extend outward in the vertical direction. The receiving groove 325 has a lateral opening facing the fixing rib 323. The fixing rib 323 is spaced from the lateral opening of the receiving groove 325. Accordingly, the thermostat 33 has a laterally extending fin 333. The tabs 333 are configured to extend in different directions.

As shown in fig. 4, when assembling, the tab 333 of the thermostat 33 may be inserted into the receiving groove 325 at a side thereof adjacent to the receiving groove 325. The receiving groove 325 vertically limits it so that the thermostat 33 can only move in the direction of the lateral opening, but remains vertically fixed with respect to the outer pot 32. At this time, the sensing end 331 of the thermostat 33 abuts against the bottom wall 321 of the outer pot 32.

Alternatively, as shown in fig. 5, the fixing rib 323 may be bent to press against the other tab 333. Thus, the thermostat 33 is fixed by the fixing rib 323 at the opposite side of the receiving groove 325. The fixing rib 323 is engaged with the receiving groove 325 to integrally fix the thermostat 33. The installation mode is simple, can be completed only by inserting and bending, is easy to operate, and can obviously improve the production efficiency.

In addition, to avoid loosening, as shown in fig. 3, the tab 333 is disposed near the sensing end 331 so that the tab 333 can abut against the bottom wall 321 of the outer pot 32 when connected to the outer pot 32.

Preferably, the opening of the receiving groove 325 is disposed opposite to the fixing rib 323, and the fins 333 of the thermostat 33 are configured to laterally extend toward opposite sides. So set up, can make temperature controller 33 atress even, fixed effect is better. However, it is understood that the tab 333 may be configured to extend at other angles in different directions so long as securement is achieved.

Preferably, at least one of the fixing rib 323 and the receiving groove 325 can be formed by punching the bottom wall 321 of the outer pot 32. The manufacturing method is very simple and easy to realize. As shown in fig. 5, the fixing rib 323 may be bent toward the thermostat 33. Therefore, the fixing rib 323 can generate a pushing force for moving the thermostat 33 toward the receiving groove 325 when bending, which is beneficial to enhancing the fixing function of the thermostat 33. In addition, after bending, the bent portion of the fixing rib 323 is pressed against the tab 333, and the fixing action in the vertical direction can be ensured.

Preferably, the receiving groove 325 remains closed in other directions except for the opening toward the fixing rib 323. That is, the receiving groove 325 has only one opening, so that the fixing action of the wing 333 can be ensured.

Preferably, as shown in fig. 3, the bottom wall 321 of the outer pot 32 is further provided with a recess 324 at a position corresponding to the sensing end 331 of the thermostat 33. It is understood that the recess 324 is recessed from the outside of the bottom wall 321 toward the inside. When the thermostat 33 is fixed to the outer pot 32, the sensing end 331 thereof is disposed in the recess 324. Therefore, the concave portion 324 can limit the temperature controller 33 in the transverse direction, so as to prevent the temperature controller 33 from moving relative to the bottom wall 321 of the outer pot 32 in the transverse direction, and facilitate fixing. On the other hand, the sensing end 331 can have a fixed and unique sensing position, which is beneficial to uniformity of sensed temperature every time, so that the control accuracy can be improved.

Preferably, the recess 324 may be made by stamping the bottom wall 321. In addition, for the thermostat 33, the distance between the fins 333 and the end of the sensing end 331 should be not less than (i.e., greater than or equal to) the depth of the recess 324. Therefore, the sensing end 331 can be tightly abutted against the inner bottom surface of the recess 324, and inaccurate temperature measurement caused by a gap is avoided.

According to the utility model discloses, be provided with holding tank and fixed muscle on the diapire of outer pot, can insert the fin in the holding tank and buckle fixed muscle and press fixed mode and fix the temperature controller on outer pot, can be from this in order to omit the spare part such as fastener and the support of being exclusively used in fixed temperature controller, can simplify the assembly process, improve production efficiency, reduce the manufacturing cost in the aspects such as manual work, time and material.
