The preferred embodiments of the present utility model 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 cover body 10 . The pot body 40 may be roughly constructed in the shape of a rounded cuboid, and an inner pot 41 is provided inside the pot body 40 . The inner pot 41 may be configured to be removably provided in the pot body 40 . For example, in one embodiment, a cylindrical inner pot accommodating portion may be provided in the pot body 40, and the inner pot 41 may be freely placed in or taken out from the inner pot accommodating portion. The removable setting allows the user to conveniently take out the inner pot 41 for cleaning. Of course, in other embodiments, the inner pot 41 may also be fixedly arranged in the pot body 40 in a non-removable manner. A heating device for heating the inner pot 41 is usually also provided in the pot body 40 .

As shown in FIG. 1 , the cover body 10 is provided on the pot body 40 in an openable and closable manner. Therefore, the cover body 10 generally has a shape adapted to the shape of the pot body 40 , so that the pot body 40 can be conveniently covered. When the cover body 10 is opened relative to the pot body 40 , the opening of the inner pot 41 in the pot body 40 is exposed, and the user can add ingredients to the inner pot 41 or take out cooked food from 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 also provided between the cover body 10 and the inner pot 41, so that the cooking space can maintain good sealing.

The cooking appliance 1 according to the present invention is also provided with a steam generating device. As shown in FIG. 2 , a steam generating device 20 is provided in the cover body 10 for generating steam for assisting cooking. Correspondingly, as shown in FIG. 4 , the cover body 10 is provided with a first steam passage 11 . When the cover 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 to assist cooking. Taking the rice cooker as an example, the specific operation of the auxiliary cooking may be, during the cooking process, the steam generated by the steam generator 20 is introduced into the cooking space, and heated from above the rice, so that the rice can be heated evenly 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, so as to maintain a good taste.

Specifically, as shown in FIGS. 2 to 4 , in this embodiment, the steam generating device 20 includes two parts, a steam generating assembly 21 and a steam sealing assembly 22 .

The steam generating assembly 21 is provided with a steam generating chamber 23 for accommodating water to be heated to generate steam. Preferably, the position of the steam generating chamber 23 can form a recessed receptacle (not shown), and a water container 27 is arranged in the receptacle. The accommodating space of the water container 27 constitutes the steam generating chamber 23 . Thus, the steam generating chamber 23 can be conveniently provided. In addition, the water container 27 may be configured to be manually detachable and disposed within the accommodating portion. The user can easily take out the water container 27 for cleaning or replacement. Of course, the steam generating chamber 23 can also be configured in other forms, for example, a concave portion formed integrally with the cover body 10 and the like.

In addition, the steam generating assembly 21 further includes a heating device for heating the water in the steam generating chamber 23 to generate steam. Therefore, the heating device may preferably be provided below or on the side of the steam generating chamber 23 . As shown in FIG. 4 , in this embodiment, the heating device 24 is configured to include a heating plate 241 and an electric heating pipe 242 . Wherein, the heating pan 241 includes a bottom wall and a side wall extending upward from an edge of the bottom wall. Thus, the bottom wall and the side walls constitute a space for accommodating the water container and surround the water container from below and from the side. The electric heating pipe 242 is arranged in the heating plate 241 . In the illustrated embodiment, the electric heating pipe 242 is provided in the side wall of the heating plate 241 . However, the electric heating pipe 242 may also be disposed in the bottom wall of the heating plate 241, or the electric heating pipe 242 may be disposed in both the side wall and the bottom wall. Of course, the heating device can also be constructed in other forms, such as an electromagnetic heating device and the like.

The steam sealing assembly 22 is connected to the cover body 10 and can be opened and closed relative to the steam generating chamber 23 . 3 and 4 show that the steam sealing assembly 22 is in a closed state, and in this state, the steam sealing assembly 22 covers the steam generating chamber 23 . The steam containment assembly 22 is shown in an open state in FIG. 2 . The user can open the steam sealing assembly 22 to observe the water level in the steam generating chamber 23 and the degree of cleanliness (whether there is scale, etc.), and then decide whether to perform operations such as adding water or cleaning the steam generating chamber 23 .

In one embodiment, the steam containment 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 position corresponding to the steam generation chamber 23 on the side facing the steam generation chamber 23 . When the steam sealing assembly 22 is in the closed state, the sealing member 26 is sandwiched between the steam cover plate 25 and the edge of the steam generating chamber 23, so as to play a sealing function and prevent steam leakage.

In order to guide the steam generated in the steam generating chamber 23 into the cooking space in a state that the steam generating chamber 23 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 can be understood that the second steam inlet 252 is located within the sealing area of the sealing element 26 , and the second steam outlet 253 is located outside the sealing area of the sealing element 26 . When the steam sealing assembly 22 is in the closed state, the second steam outlet 253 is connected to the first steam inlet (not shown) of the first steam passage 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 through the butted second steam outlet 253 and the first steam inlet 11. Finally, the first steam outlet 112 flowing out of the first steam channel 11 enters the cooking space below the cover body 10 .

In addition, as shown in FIGS. 4 and 5 , the cover body 10 is further provided with a heat insulating device. The thermal insulation device is used to at least partially isolate the steam generating device 20 from the cover body 10 to reduce unnecessary heat exchange therebetween. In other words, the thermal insulation device is used to reduce the undesired heat transfer from the steam generating device 20 to the cover body 10, so as to prevent the parts of the cover body 10 close to the steam generating device 20 from being overheated and affecting the operation.

In the steam generating device 20, the heating device 24, as a heat source, has the highest temperature, so it also transfers the most heat to the outside. As shown in FIG. 4, the thermal insulation device is configured as a thermal shield 30 that includes a bottom wall and side walls extending upwardly from an edge of the bottom wall. The heat shield 30 surrounds the heating device 24 from below and from the side. Therefore, the heat shield 30 reduces the heat transfer of the heating device 24 to the lower and outer sides thereof, so that the heat generated by the heating device 24 is concentrated to the upper and inner steam generating chambers 23, thereby reducing unnecessary heat exchange at the same time. , can also improve the utilization of heat.

Preferably, the separation distance between the walls of the heat shield 30 (including the side walls and the bottom wall) and the heating device 24 is less than or equal to 15 mm. This is because, when the distance between the parts of the cover 10 and the heating device 24 exceeds 15 mm, the air between the two has good thermal insulation capability, and the heat transferred from the heating device 24 has been minimized. Therefore, it is only necessary to provide the heat shield 30 within a range of 15 mm from the heating device 24 . Preferably, according to the size of the cover body 10, in order to make the structure compact, the distance between the heat shield 30 and the heating device 24 can be selected as 13mm, 10mm, 7mm, 5mm or 3mm, etc.

Preferably, the heat shield 30 may be made of iron-galvanized or iron-aluminized sheet. As a result, the inner wall surface of the heat shield 30 can reflect the heat radiation emitted by the heating device 24 , so that the heat radiation can be concentrated in the area surrounded by the heat shield 30 . Of course, the heat shield 30 can also be made of other materials with low thermal conductivity, which can play a role of heat insulation by reducing the heat exchange capability of the heat shield 30 .

During the working process, the temperature of the heat shield 30 is also relatively high due to its proximity to the heating device 24 . Further preferably, as shown in FIG. 5 , the heat shield 30 is connected and fixed to the cover body 10 through the fixing frame 302 instead of being directly connected to the cover body 10 . The fixing frame 302 is made of a material with a low thermal conductivity, such as a plastic material. Therefore, the fixing frame 302 can prevent the heat shield 30 from transferring heat to the cover body 10 by means of heat conduction.

In order to facilitate connection, the outer side wall surface of the heat shield 30 is provided with a connection portion 301 protruding outward, and a connection hole is provided thereon. The connecting portion 301 can be connected to the fixing frame 302 by fasteners such as screws or rivets, and then the fixing frame 302 can be connected to the cover body 10 . In order to maintain a stable and firm connection, four connecting parts 301 are provided at even intervals along the circumferential direction. Of course, the number of the connection portion 301 and the fixing frame 302 connected thereto is not limited to this, and can be reasonably set on the premise of ensuring the connection strength.

In addition, a limit ring 31 is also provided on the top of the heat shield 30 . The upper edge of the heat shield 30 abuts on the limiting ring 31 for fixing and limiting the heat shield 30 in the up-down direction. The limiting ring 31 is preferably made of a material with a low thermal conductivity, such as a plastic material, and at the same time can play a role of heat insulation. As shown in FIG. 4 , the limiting 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 , which can facilitate the installation and positioning between the two.

Although the three-dimensional structure of the limit ring 31 is not shown in the figure, it can be understood that the limit ring 31 surrounds the heat shield 30 in a circumferential direction, and extends from the upper edge of the heat shield 30 to the radial direction of the heat shield 30 . It extends inward and abuts against the outer wall of the steam generating chamber 23 . Thereby, the limiting ring 31 closes the upper opening of the heat shield 30 to form a relatively closed space inside, which further prevents the heat from being transferred and dissipated to the outside.

As can be seen from FIG. 4 , above the limiting ring 31 , the components of the cover body 10 and the limiting ring 31 are at least partially spaced apart. In other words, the limiting ring 31 is spaced apart from the components 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. Therefore, the gap 312 can reduce the continued upward transfer of heat through the limiting ring 31 . Wherein, the gap 312 can be formed by being supported between the limiting ring 31 and/or the upper parts thereof by supporting ribs provided on the limiting ring 31 .

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

In the present embodiment, the steam generating chamber 23 is configured in the form of a water container 27, and the water container 27 is provided in a removable manner. Therefore, a heat insulating pad 272 is provided on the outer wall of the opening position of the water container 27 . The heat insulating pad 272 can be made of a material with low thermal conductivity such as plastic or rubber, and is attached to the outer wall. Thus, the thermal insulation pad 272 can reduce the heat transfer of the water container 27 to the outside at the opening. At the same time, if the water container 27 needs to be taken and placed when the temperature of the water container 27 is high, the heat insulating pad 272 can also play a role of preventing scalding. As shown in FIG. 4 , the water container 27 is provided with a flange 271 extending laterally outward at the opening. The heat insulating pads 272 are provided below and outside the flanges 271 . In this way, heat insulation can be achieved under the flange 271 . Of course, the heat insulating pad 272 can also be provided only below or outside the flange 271 as required.

Further, in order to prevent the temperature from being too high, the cooking appliance 1 is further provided with a thermostat 60 to control 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 to avoid danger. Still further, a fuse 50 is also provided. When the current of the heating device 24 is too large (eg short circuit) or continues to heat due to runaway, the fuse 50 disconnects the circuit supplying power to the heating device 24 by fusing to avoid danger. As shown in FIG. 5 , both the thermostat 60 and the fuse 50 are provided in the cover body 10 .

According to the cooking utensil of the present invention, a heat insulating device is provided between the steam generating device and the cover, which at least partially separates the two, thereby reducing unnecessary heat exchange between the steam generating device and the cover, avoiding unnecessary heat exchange between the steam generating device and the cover. In case the cover temperature is too high.
