The utility model provides a cooking utensil. 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 preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the cooking appliance 1 according to the present invention may include a pot body 40 and a lid body 10. The pot body 40 may be substantially configured in a rounded rectangular parallelepiped shape, and an inner pot 41 is provided inside thereof. The inner pot 41 may be configured to be removably disposed in the pot body 40. For example, in one embodiment, the pot body 40 may be provided with a cylindrical inner pot receiving portion, and the inner pot 41 may be freely put into or taken out of the inner pot receiving portion. The removable arrangement allows the user to easily remove the inner pot 41 for cleaning. Of course, in other embodiments, the inner pot 41 may be fixedly provided in the pot body 40 in a non-removable manner. The pot body 40 is also usually provided therein with a heating means for heating the inner pot 41.

As shown in fig. 1, the lid body 10 is provided to the pot body 40 in a manner openable and closable. Therefore, the lid body 10 generally has a shape conforming to the shape of the pot body 40, so that the pot body 40 can be easily covered. When the lid body 10 is opened with respect to the pot body 40, the opening of the inner pot 41 in the pot body 40 is exposed, and the user can add food materials to the inner pot 41 or take cooked food out of the inner pot 41. When the lid body 10 is closed on the pot body 40, it covers the inner pot 41 and forms a cooking space with the inner pot 41. A sealing member is further provided between the cover body 10 and the inner pot 41 to maintain a good sealing property of the cooking space.

According to the utility model discloses a cooking utensil 1 still is provided with steam generator. As shown in fig. 2, a steam generating device 20 for generating steam for assisting cooking is provided in the cover 10. Accordingly, as shown in fig. 4, a first steam passage 11 is provided on the cover 10. In a state where the lid body 10 covers the pot body 40, the steam generating device 20 can communicate with the cooking space through the first steam passage 11 so as to introduce steam into the cooking space for assisting cooking. Taking an electric cooker as an example, the specific operation of the auxiliary cooking may be to introduce the steam generated by the steam generating device 20 into the cooking space during the cooking process, and heat the rice from above, so that the rice can be uniformly heated, and the heating efficiency is improved; alternatively, after the rice is cooked, the steam generated by the steam generator 20 may be introduced into the cooking space to keep the rice warm and fresh, thereby maintaining a good taste.

Specifically, as shown in fig. 2 to 4, in the present embodiment, the steam generating device 20 includes two parts, namely, a steam generating component 21 and a steam sealing component 22.

The steam generating assembly 21 is provided with a steam generating chamber 23 for containing water to be heated for generating steam. Preferably, the steam generating chamber 23 may be positioned to form a recessed receiving portion (not shown), and a water container 27 is provided in the receiving portion. The accommodating space of the water container 27 constitutes the steam generating chamber 23. Thereby, the steam generating chamber 23 can be conveniently provided. Further, the water container 27 may be configured to be disposed in the accommodating portion in a manually detachable manner. The user can conveniently take out the water container 27 for cleaning or replacement. Of course, the steam generating chamber 23 may also be configured in other forms, such as a recess integrally formed with the cover 10.

Furthermore, the steam generating assembly 21 comprises heating means for heating the water inside the steam generating chamber 23 to generate steam. Therefore, the heating means may preferably be provided below or at the side of the steam generating chamber 23. As shown in fig. 4, in the present embodiment, the heating device 24 is configured to include a heating pan 241 and an electric heating tube 242. Wherein the heating pan 241 includes a bottom wall and a side wall extending upward from an edge of the bottom wall. Thereby, the bottom wall and the side wall constitute a space for accommodating the water container and surround the water container from below and from the sides. The electric heating tube 242 is disposed in the heating plate 241. In the illustrated embodiment, the electric heating tube 242 is disposed inside a sidewall of the heating pan 241. However, the electric heating tube 242 may be provided in the bottom wall of the heating pan 241, or the electric heating tube 242 may be provided in both the side wall and the bottom wall. Of course, the heating device can also be configured in other forms, such as an electromagnetic heating device or the like.

The steam sealing member 22 is connected to the cover 10 and can be opened and closed with respect to the steam generating chamber 23. Fig. 3 and 4 show the steam seal 22 in a closed state, in which the steam seal 22 closes the steam generating chamber 23. The steam containment assembly 22 is shown in an open state in fig. 2. The user can observe the water level and the degree of cleanliness (whether scale is present, etc.) in the steam generation chamber 23 by opening the steam sealing member 22, and then decide whether to perform operations such as adding water or cleaning the steam generation chamber 23.

In one embodiment, the steam enclosure assembly 22 may be configured in the form of a steam cover plate 25, and the steam cover plate 25 is provided with a seal 26 at a location corresponding to the steam generating chamber 23 on a side facing the steam generating chamber 23. When the steam-tight assembly 22 is in the closed state, the sealing member 26 is interposed between the steam cover plate 25 and the edge of the steam generating chamber 23 to perform a sealing function and prevent steam from leaking.

In order to guide the steam generated in the steam generation chamber 23 into the cooking space in a state where it is sealed by the sealing member 26, a second steam passage 251 is provided on the steam cover plate 25. The second steam passage 251 has a second steam inlet 252 and a second steam outlet 253. It will be appreciated that the second steam inlet 252 is located within the sealing area of the seal 26 and the second steam outlet 253 is located outside the sealing area of the seal 26. When the steam enclosure assembly 22 is in the closed state, the second steam outlet 253 interfaces with a first steam inlet (not shown) of the first steam channel 11. As shown in fig. 4, the steam generated in the steam generating chamber 23 can flow into the second steam passage 251 through the second steam inlet 252, continue to flow, and enter the first steam passage 11 through the butted second steam outlet 253 and first steam inlet. And finally flows out of the first steam outlet 112 of the first steam channel 11 into the cooking space under the cover 10.

As shown in fig. 4 and 5, a heat insulating device is provided in the lid body 10. The heat insulation means serves to at least partially insulate the steam generating means 20 from the cover 10 to reduce unnecessary heat exchange therebetween. In other words, the thermal insulation means is used to reduce the undesired heat transfer from the steam generating device 20 to the cover 10, and avoid the temperature of the parts of the cover 10 close to the steam generating device 20 from being too high to affect the operation.

In the steam generator 20, the heating device 24 has the highest temperature as a heat source, and thus the heat quantity transferred to the outside is also the largest. As shown in fig. 4, the heat insulation means is configured as a heat shield 30 including a bottom wall and a side wall extending upward from an edge of the bottom wall. The heat shield 30 surrounds the heating device 24 therein from below and from the sides of the heating device 24. Therefore, the heat shield 30 reduces the heat transfer from the heating device 24 to the lower and outer sides thereof, so that the heat generated by the heating device 24 is concentrated more toward the steam generating chamber 23 on the upper and inner sides thereof, thereby reducing unnecessary heat exchange and improving the heat utilization rate.

Preferably, the walls (including the side and bottom walls) of the heat shield 30 are spaced from the heating device 24 by a distance less than or equal to 15 mm. This is because, when the parts of the lid body 10 are spaced from the heating device 24 by more than 15mm, the air itself between the two has a good heat insulating ability, and the heat transfer from the heating device 24 has been minimized. Therefore, the heat shield 30 only needs to be disposed within 15mm from the heating device 24. Preferably, the distance between the heat shield 30 and the heating device 24 can be selected to be 13mm, 10mm, 7mm, 5mm, 3mm, or the like, according to the size of the cover 10, in order to make the structure compact.

Preferably, the heat shield 30 may be made of a sheet material that is iron-galvanized or iron-aluminized. Thus, the inner sidewall surface of the heat shield 30 reflects the heat radiation emitted from the heating device 24, concentrating the heat radiation in the area surrounded by the heat shield 30. Of course, the heat shield 30 may be made of other materials with small thermal conductivity, and the heat shield may perform a heat insulation function by reducing the heat exchange capability of the heat shield 30.

During operation, the heat shield 30 itself is also at a higher temperature due to its proximity to the heating device 24. Further preferably, as shown in fig. 5, the heat shield 30 is fixed to the cover 10 by a fixing frame 302, rather than being directly connected to the cover 10. The fixing frame 302 is made of a material with a small thermal conductivity, such as a plastic material. Thus, the fixing frame 302 can prevent the heat shield 30 from transferring heat to the cover 10 by means of heat conduction.

For the convenience of connection, the outer side wall surface of the heat shield 30 is provided with a connection portion 301 protruding outward, on which a connection hole is provided. The connection portion 301 may be connected to the fixing frame 302 by a fastener such as a screw or a rivet, and then the fixing frame 302 may be connected to the cover 10. In order to maintain a stable and firm connection, four connection portions 301 are provided at regular intervals in the circumferential direction. Of course, the number of the connecting portions 301 and the fixing frames 302 connected thereto is not limited thereto, and may be reasonably set on the premise of ensuring the connection strength.

In addition, a stopper ring 31 is provided on the top of the heat shield 30. The upper edge of the heat shield 30 abuts on the stopper ring 31, and is used for fixing and stopping the heat shield 30 in the up-down direction. The stop collar 31 is preferably made of a material with a low thermal conductivity, such as a plastic material, and can also serve as a heat shield. As shown in fig. 4, the retaining ring 31 is provided with a positioning groove 311, and the upper edge of the heat shield 30 is clamped in the positioning groove 311, so as to facilitate installation and positioning between the two.

Although the perspective structure of the retainer ring 31 is not shown in the drawings, it is understood that the retainer ring 31 surrounds the heat shield 30 circumferentially and extends from the upper edge of the heat shield 30 radially inward of the heat shield 30 and abuts against the outer side wall of the steam generation chamber 23. Therefore, the retainer ring 31 closes the upper opening of the heat shield 30 to form a relatively closed space therein, thereby further preventing heat from being transferred and dissipated to the outside.

As can be seen from fig. 4, above the stop collar 31, the components of the cover 10 are at least partially spaced from the stop collar 31. In other words, the stop collar 31 is spaced from the component above it to form a gap 312. It will be appreciated that this gap 312 is filled with air, and that air is a poor conductor of heat. Thus, the gap 312 may reduce the continued upward transfer of heat through the stop collar 31. Wherein the gap 312 can be formed by supporting the support rib arranged on the limiting ring 31 and/or the upper part thereof.

Preferably, a support member 32 is further disposed in the relatively closed space, and is supported between the limiting ring 31 and the heating device 24 in the up-down direction. In addition, the supporting member 32 may also be made of a material with a low thermal conductivity, such as a plastic material, which may further insulate heat.

In the present embodiment, the steam generation chamber 23 is constructed in the form of a water container 27, and the water container 27 is removably provided. Therefore, a heat insulating pad 272 is provided on the outer wall of the water container 27 at the opening position. The insulation pad 272 may be made of a material having a low thermal conductivity, such as plastic or rubber, and attached to the outer wall. Thus, the insulation pad 272 may reduce the transfer of heat from the water container 27 to the outside at the opening. Meanwhile, if the water container 27 needs to be taken and placed when the temperature of the water container 27 is high, the heat insulation pad 272 can also play a role in preventing scalding. As shown in fig. 4, the water container 27 is provided with a flange 271 extending outward in the lateral direction at the opening. Insulation pad 272 is disposed below and outside cuff 271. Therefore, the heat insulation effect can be achieved below the flanging 271. Of course, insulation pad 272 may be provided only below or outside cuff 271 as desired.

Further, in order to avoid the temperature from being too high, the cooking appliance 1 is further provided with a temperature controller 60 for controlling the heating operation of the heating device 24. When the temperature exceeds a preset predetermined value, the thermostat 60 controls the heating device 24 to stop heating so as not to cause danger. Still further, a fuse 50 is also provided. When the heating device 24 is subjected to excessive current (e.g., short circuit) or continues to heat due to runaway, the fuse 50 opens the circuit for supplying power to the heating device 24 by blowing, so as not to cause danger. As shown in fig. 5, the thermostat 60 and the fuse 50 are both disposed in the cover 10.
