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. Referring to fig. 4 again, 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 temperature controller 33 on the outer pot 32, as shown in fig. 2 and 4, the outer side surface of the bottom wall 321 of the outer pot 32 is provided with a positioning rib 323. The positioning rib 323 is spaced from the bottom wall 321 and extends in a direction substantially parallel to the bottom wall 321. Thereby, an accommodation space is formed between the positioning rib 323 and the bottom wall 321. Preferably, the positioning rib 323 can be formed by stamping the bottom wall 321 of the outer pot 32. The manufacturing method is very simple and easy to realize. Accordingly, the thermostat 33 has a laterally extending fin 333.

As shown in fig. 4, when assembled, the thermostat 33 may be positioned vertically by snapping the tabs 333 between the positioning ribs 323 and the bottom wall 321. Referring again to fig. 5, after the tabs 333 snap under the positioning ribs 323, the positioning ribs 323 may preferably be bent toward the bottom wall 321 to press against the tabs 333. This prevents the tab 333 from coming out from under the positioning rib 323.

Preferably, the tabs 333 are configured to extend toward opposite sides, respectively. Accordingly, the positioning rib 323 includes two and is respectively located at both sides of the thermostat 33. Each tab 333 snaps under a corresponding positioning rib 323. In this way, the fins 333 can be fixed to both sides of the thermostat 33, and the fixing strength can be increased. Further, as shown in fig. 4, the positioning ribs 323 located at both sides of the thermostat 33 extend in opposite directions. Therefore, the temperature controller 33 can be rotated to insert the fins 333 into the lower portions of the corresponding positioning ribs 323, thereby facilitating installation. On the other hand, the positioning ribs 323 have openings with different orientations. When the thermostat 33 moves in a certain direction in a lateral direction with respect to the outer pot 32, the positioning rib 323 closed in that direction may act as a barrier to keep the thermostat 33 fixed. Whereby the firmness can be increased.

As an alternative embodiment, the positioning ribs 323 at both sides of the thermostat 33 may be configured to extend toward the same direction. The thermostat 33 snaps the fins 333 into place under the corresponding positioning ribs 323 by translating in a certain direction.

Preferably, although not shown in the drawings, it is understood that the bottom wall 321 of the outer pot 32 may be further provided with a recess at a position corresponding to the sensing end 331 of the thermostat 33. The recess may be recessed from the outside toward the inside of the bottom wall 321. When the thermostat 33 is fixed to the outer pot 32, the sensing end 331 thereof is disposed in the recess. Therefore, the concave part can limit the temperature controller 33 along the transverse direction, so that the temperature controller 33 is prevented from moving relative to the bottom wall 321 of the outer pot 32 along the transverse direction, and the fixing is facilitated. 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 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. Therefore, the sensing end 331 can be tightly abutted against the inner bottom surface of the concave part, and inaccurate temperature measurement caused by a gap is avoided.
