[0058] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.
[0059] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.
[0060] The utility model provides a cooking utensil, which can be an electric rice cooker, an electric pressure cooker, an air fryer, a stew pot, a steamer, a frying machine, an oven, a cooking machine, an electric kettle or other cooking utensil.
[0061] The cooking utensil comprises a cover 10 and a pot body. The pot body is used for cooking food, and the cover 10 is used to cover the pot body, for example, the cover 10 is connected to the pot body in an openable and closable manner, and is used to cover the pot body. When the cover 10 covers the pot body, a cooking space is formed between the cover 10 and the pot body.
[0062] It should be noted that the directional terms used herein to describe the various components, parts, etc. of the cooking appliance, such as "up", "down", "above", "below", "upward", "downward", "upward", "downward", etc., are relative to the cooking appliance in a horizontal and upright state. If there is no other qualification, the directional terms "inward", "outward", "inwardly", "outwardly", "inside", "outside", etc., in which "inside" refers to the direction close to the center of the cooking appliance, and "outside" refers to the direction away from the center of the cooking appliance.
[0063] The pot body is provided with a pot inner body for accommodating food materials, a heating device, a control module and a temperature sensor. The pot inner body for holding food materials is removably arranged in the pot body. When the cover body 10 covers the pot body, a cooking space is formed between the cover body 10 and the pot inner body. The heating device is arranged at the bottom of the pot body, below the pot inner body, to heat the food in the pot inner body. The control module can be, for example, a micro control unit (MCU) for realizing cooking control of the cooking utensil. The temperature sensor is used to detect the temperature of the pot inner body, which can be arranged at the cover body 10, the bottom center of the pot body, or at the side of the pot body. The heating device and the temperature sensor are both electrically connected to the control module. The temperature sensor feeds back the sensed temperature to the control module, so that the control module can realize more precise control of, for example, the heating device based on the temperature information.
[0064] like Figure 1As shown, the cover body 10 includes a face cover, an inner lining 11 and a removable cover 12. The face cover is located at the outermost side (i.e., the uppermost side) of the cover body 10 to form the outer shell of the cover body 10. The inner lining 11 is arranged below the face cover and connected to the face cover. For example, the inner lining 11 can be connected to the face cover by fasteners or buckles. The inner lining 11 is mainly used to centrally install various functional parts of the cover body 10 that sense and control the working state of the cooking appliance, such as sensors, control modules, etc. The removable cover 12 is located at the innermost side (i.e., the lowermost side) of the cover body 10 and is arranged below the inner lining 11. The removable cover 12 is detachably connected to the inner lining 11, for example, by a buckle connection, so as to facilitate cleaning and replacement. The removable cover 12 is used to face the cooking space, that is, when the cover body 10 is covered on the pot body, the removable cover 12 is located directly above the cooking space. The removable cover 12 is made of metal material.
[0065] A sandwich layer may be formed between the inner liner 11 and the removable cover 12 to arrange a steam channel. During the cooking process, water vapor generated by heating food rises through the steam channel and enters the sandwich layer between the inner liner 11 and the removable cover 12. The steam channel is arranged in the sandwich layer to discharge steam in a preset manner.
[0066] In the present utility model, if Figure 2-4 As shown, the lining 11 is provided with a mounting hole 111. The mounting hole 111 is connected to the interlayer between the lining 11 and the removable cover 12. The removable cover 12 has a first surface and a second surface arranged opposite to each other, the first surface facing the lining 11, and the second surface facing the pot body. The heating element 20 is fixed to the mounting hole 111, and the heating element 20 contacts the second surface for heat transfer. Among them, the heating element 20 is electrically connected to the control module. During cooking or after cooking of the cooking utensil, the heating element 20 can be heated by the control module, and the heating element 20 transfers the temperature to the removable cover 12. The removable cover 12 with the increased temperature can then evaporate the condensed water on the surface, avoiding the accumulation of condensed water on the surface of the removable cover 12. In this embodiment, the heating element 20 is directly fixed to the cover body 10 through the mounting hole 111, and can be easily disassembled and replaced without the need for an additional adhesive layer. In the utility model, the heating element 20 adopts a heating rod. Optionally, the heating rod is a resistance wire heating rod, a ceramic heating rod, etc. The heating rod is an independent component and can be used directly. In the present invention, since the heating element 20 is fixedly mounted to the lining 11 and is in contact with the removable cover 12, the user will not affect the heating element when removing and cleaning the removable cover 12, and the problem of residual adhesive on the insulation line is avoided, making the product easier to maintain and clean. Since there is no insulation line on the removable cover 12, the safety risks that may be caused when the removable cover 12 contacts water are avoided. In the present invention, the heating element 20 will not interfere with the normal use of the removable cover 12, ensuring the normal function of the product.
[0067] In some embodiments of the utility model, the cover body 10 is further provided with a seal 30, which is arranged between the inner peripheral wall of the mounting hole 111 and the outer peripheral wall of the heating element 20. That is, the seal 30 is nested between the mounting hole 111 and the heating element 20, the inner peripheral wall of the seal 30 is sealed and connected to the heating element 20, and the outer peripheral wall of the seal 30 is sealed and connected to the mounting hole 111. With the arrangement of the seal 30, during the cooking process of the cooking utensil, water vapor enters the upper part of the liner 11 through the mounting hole 111, thereby reducing the damage of water vapor to the electronic components above the liner 11. Optionally, the seal 30 is made of a heat-insulating non-metallic material. Exemplarily, the seal 30 is made of materials such as silicone, plastic, etc. The heat-insulating performance of the seal 30 can isolate the heat generated by the heating element 20 to a certain extent, prevent excessive heat from being transferred to the upper part of the liner 11, thereby reducing the influence of the heating element 20 on the liner 11. The electrical insulation performance of the seal 30 prevents the electric heating element from contacting the liner 11 or other components to cause a short circuit, thereby improving the safety of the use of the heating element 20. The seal 30 can also have a certain buffering effect, reduce the impact of vibration on the heating element 20, and reduce the wear of the heating element 20 during use.
[0068] In some embodiments of the present invention, Figure 5 As shown, at least one end of the seal 30 in the axial direction is provided with a first flange 31 extending radially outward, and the first flange 31 is in contact with the liner 11. That is, the seal 30 is in contact with the upper surface and / or lower surface of the liner 11, further enhancing the sealing performance of the seal 30. It can be understood that the radial dimension of the first flange 31 is greater than the radial dimension of the mounting hole 111, thereby realizing the upper limit of the axial direction of the seal 30, preventing the seal 30 from loosening or falling off due to vibration or other reasons during operation, and ensuring that the seal 30 can be correctly positioned and fixed during installation.
[0069] In some embodiments of the present invention, Figure 6 As shown, the heating element 20 is provided with a second flange 21 extending radially outward, and the second flange 21 is in contact with the sealing element 30. That is, the second flange 21 is sealed and connected with the sealing element 30, further enhancing the sealing effect between the heating element 20 and the sealing element 30.
[0070] On the basis of the above embodiment, the second flange 21 is arranged above the mounting hole 111, and the radial dimension of the second flange 21 is greater than the radial dimension of the inner peripheral wall of the sealing member 30. It can be understood that the second flange 21 is located above the sealing member 30. While strengthening the sealing effect, the second flange 21 limits the axial downward movement of the heating member 20, prevents the heating member 20 from loosening or falling off due to vibration or other reasons during operation, and ensures that the heating member 20 can be correctly positioned and fixed during installation. At the same time, since the second flange 21 is located above the sealing member 30, it is convenient for the heating member 20 to be disassembled and installed.
[0071] In some embodiments of the present invention, the cooking appliance further comprises a fixing frame 40, which is used to fix the heating element 20. The fixing frame 40 is disposed at least partially above the heating element 20, and in a plane perpendicular to the axial direction, the projection of the fixing frame 40 at least partially overlaps with the projection of the heating element 20. The fixing frame 40 limits the axial upward movement of the sealing element 30.
[0072] In some embodiments of the present invention, Figure 7-8 As shown, the fixing frame 40 is provided with a fixing hole 41, the heating element 20 is passed through the fixing hole 41, and the second flange 21 is located between the liner 11 and the fixing frame 40. The setting of the fixing frame 40 does not affect the sealing effect of the heating element 20 while achieving fixation.
[0073] On the basis of the above embodiment, the radial dimension of the fixing hole 41 is larger than the radial dimension of the end of the heating element 20, and the radial dimension of the fixing hole 41 is smaller than the radial dimension of the second flange 21. The fixing frame 40 is sleeved on the heating element 20, and the fixing frame 40 can be pressed on the second flange 21, so as to fix the heating element 20 and enhance the sealing effect between the heating element 20 and the sealing element 30.
[0074] In some embodiments of the present invention, the fixing frame 40 is configured as an annular structure. The fixing frame 40 is arranged in an annular shape, and can be stably mounted to the liner 11 to avoid displacement while limiting the axial downward position of the heating element 20. Exemplarily, the liner 11 is provided with an annular wall so that the fixing frame 40 is fitted to the annular wall to limit the radial displacement of the fixing frame 40. Exemplarily, the liner 11 is provided with a limiting member, and the limiting member overlaps with a portion of the fixing frame 40 in the projection in a plane perpendicular to the axial direction to limit the axial displacement of the fixing frame 40.
[0075] In some embodiments of the present invention, a plurality of heating elements 20 are connected to the same fixing frame 40, thereby simplifying the installation and maintenance process.
[0076] In some embodiments of the utility model, a plurality of heating elements 20 are arranged in an array and installed at the edge of the liner 11. In order to reduce the impact on other components, the heating element 20 is generally arranged near the edge of the liner 11. The arrangement of multiple heating elements 20 achieves rapid heating and efficient evaporation of water vapor. It can be understood that the heating elements 20 can be arranged in a certain form according to needs, or densely arranged in a local area. Exemplarily, the heating elements 20 are arranged in an arc shape.
