Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a cooking utensil. Background Art

[0002] Existing cooking appliances, such as grills, are typically equipped with thermostats. These thermostats typically consist of a temperature sensor and a housing positioned outside the sensor. During operation, the housing contacts the cooking container, transferring heat from the container to the housing, which then transfers it to the temperature sensor, thereby detecting the temperature. The fit between the temperature sensor and the housing significantly affects the accuracy of temperature detection, and existing research has addressed this issue.

[0003] For example, patent CN205880706U discloses a thermostat comprising a fixedly connected aluminum cover and bracket, which together form a mounting cavity containing a thermistor. To ensure the thermistor's tight fit against the aluminum cover, an elastic member is positioned below the thermistor to press it upward. Furthermore, a spring is positioned at the lower end of the bracket to ensure the thermostat maintains different compression states depending on operating conditions. This patent utilizes two elastic members, one to maintain the thermistor's tight fit against the aluminum cover and the other to ensure the thermostat's floating mounting. This results in a relatively complex structure and high cost.

[0004] In addition, the prior art also has a solution of directly fixing the temperature sensing element on the inner surface of the shell, such as fixing the temperature sensing element to the shell by gluing, riveting, etc. This solution has the problem that the temperature sensing element is easy to loosen after long-term use, which affects the fit between the temperature sensing element and the shell, which is not conducive to improving the accuracy and reliability of temperature detection. Utility Model Content

[0005] The utility model provides a cooking utensil, which aims to solve the problem of a complicated structure and high cost of a temperature control component caused by the prior art that a temperature sensing element is movably arranged in a heat-conducting shell and two elastic members are required: one is arranged below the temperature sensing element to hold the temperature sensing element close to the heat-conducting shell, and the other is arranged outside the temperature control component to make the temperature control component contact with the cooking container, thereby improving the temperature measurement accuracy of the temperature sensing element.

[0006] The utility model discloses a cooking utensil, comprising an outer shell and a cooking container arranged on the outer shell, a heating plate is provided between the outer shell and the cooking container, the heating plate is provided with an avoidance hole, a detection assembly is provided between the heating plate and the outer shell, the detection assembly comprises a first shell, a temperature sensing element, a pressure ring, an elastic member and a second shell, the first shell has an accommodating cavity with an opening facing downward, the pressure ring moves along the side wall of the accommodating cavity in a direction away from the opening under the action of the elastic member, so that the pressure ring abuts the temperature sensing element against the inner top wall of the accommodating cavity, the second shell is fixed to the heating plate, at least a portion of the first shell can extend from the avoidance hole, and the first shell floats up and down along the avoidance hole relative to the second shell through the elastic member.

[0007] The cooking utensil of the present invention also has the following additional technical features:

[0008] The temperature sensing element includes a horizontally extending temperature sensing portion and a vertically extending connecting portion connected to the bottom of the temperature sensing portion. The top of the pressure ring is provided with a receiving groove, and the side wall of the pressure ring is provided with an avoidance recess. After the temperature sensing portion is embedded in the receiving groove and the connecting portion is embedded in the avoidance recess, the pressure ring moves along the side wall of the accommodating cavity in a direction away from the opening.

[0009] One of the first shell and the second shell is provided with a limiting portion, and the other is provided with a matching portion that matches the limiting portion, so that the first shell can be movably connected to the second shell.

[0010] The limiting portion is a hook provided on the first shell and extending toward the second shell, the matching portion is an assembly hole provided on the second shell, and the hook has a first position hooked on the outer edge of the assembly hole and a second position sliding to below the assembly hole.

[0011] When the first shell is fixed to the heating plate through the second shell, the first shell is sandwiched between the second shell and the heating plate.

[0012] The pressure ring has a pressure ring side wall surrounding the upper end of the elastic member, which is used to limit the radial deviation of the elastic member and provide guidance for the axial movement of the elastic member.

[0013] The second shell has a shell side wall extending upward and a flange portion extending outward from the top end of the shell side wall. The flange portion is provided with a screw hole, and the heating plate is provided with a screw column extending downward and corresponding to the screw hole.

[0014] The bottom of the second shell is provided with a through hole for the connecting portion or a wire connected to the connecting portion to pass through.

[0015] The bottom wall of the second shell is provided with a positioning column extending upward, and the lower end of the elastic member is sleeved on the positioning column.

[0016] A step portion extending radially outward is provided at the bottom end of the side wall of the accommodating cavity. The outer diameter of the step portion is larger than the diameter of the avoidance hole. The step portion is used to limit the distance that the first shell moves upward along the avoidance hole.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] 1. In the prior art, two elastic parts are used to respectively realize the assembly of the thermostat itself and the installation of the thermostat on the cooking utensil. The number of accessories is large, resulting in a complex structure and high cost. In order to solve this problem, the detection component of the present application only needs one elastic part to meet the assembly of the detection component itself and the floating installation of the detection component. It uses fewer accessories, has a relatively simple structure, and is low in cost. Moreover, the use of the elastic part to support the temperature sensing element can ensure that the temperature sensing element is always in close contact with the first shell. At the same time, the first shell can be in close contact with the cooking container due to the elastic force of the elastic part. Then, when the temperature is transferred from the cooking container to the first shell, and then from the first shell to the temperature sensing element, the accuracy of the temperature detection can be guaranteed.

[0019] 2. The temperature sensing element is arranged between the first shell and the pressure ring. The top of the pressure ring is provided with a receiving groove that can accommodate the temperature sensing part of the temperature sensing element. The temperature sensing part is usually thin. When installing the temperature sensing element, if the temperature sensing element is first installed into the receiving cavity and then the pressure ring is installed upward, it is easy for the receiving groove of the pressure ring to be difficult to align with the temperature sensing part. When an assembly error occurs, it will affect the pushing effect of the pressure ring on the temperature sensing element, which is not conducive to making the temperature sensing element evenly contact with the inner top wall of the receiving cavity, thereby affecting the accuracy of temperature detection. In order to avoid the above situation, the present application first embeds the temperature sensing part into the receiving groove and then installs the pressure ring and the temperature sensing element as a whole into the receiving cavity. It can ensure that under the action of the elastic member, the pressure ring evenly pushes the temperature sensing part so that it is close to the inner top wall of the receiving cavity, thereby ensuring the accuracy of temperature detection.

[0020] 3. The detection component of the present application can be installed with the heating plate after being assembled into an integral structural part, that is, the first shell is connected to the second shell and wraps the internal components together, which can prevent the components from being scattered during the installation of the detection component and affecting the installation efficiency; and the first shell is movably connected to the second shell, which provides conditions for the first shell to float after the installation of the detection component, so that the user can press down the first shell when placing the cooking container, and the first shell compresses the elastic part so that the elastic part provides an upward elastic force to push the first shell tightly against the cooking container, thereby ensuring the accuracy of temperature detection.

[0021] 4. The detection component of the present application does not need to be assembled into an integral structural component, but the components can be installed in sequence in a certain order. In this way, the structure for connection between the first shell and the second shell can be omitted, thereby simplifying the structure. Moreover, the method of clamping the first shell by the second shell and the heating plate can ensure that the detection component as a whole is firmly installed on the heating plate.

[0022] 5. In the absence of a certain limit, the elastic part is prone to deflection during axial movement, which is not conducive to the elastic force of the elastic part being fully supplied to other components, affecting the contact effect between the temperature sensing element and the inner top wall of the accommodating cavity or the first shell and the cooking container. The present application arranges the side wall of the pressure ring around the upper end of the elastic part, which can prevent the elastic part from deflecting significantly and provide movement guidance for the elastic part.

[0023] 6. The connection part of the temperature sensing element is connected to the control board through an electric wire. By setting a through hole at the bottom of the second shell, the connection part or the electric wire can be conveniently extended from the through hole to connect with the control board, thereby ensuring the reliability of the detection component.

[0024] 7. In order to prevent the elastic member from moving in the axial direction and affecting the pushing effect of the elastic member on the pressure ring, the bottom wall of the second shell is provided with an upwardly extending positioning column to achieve axial limitation of the elastic member.

[0025] 8. When the first shell is not connected to the second shell, in order to prevent the first shell from completely falling out of the avoidance hole during the upward floating process, it is necessary to limit the upward movement distance of the first shell. By setting a step portion with an outer diameter larger than the diameter of the avoidance hole, the step portion can be blocked below the avoidance hole, and only a part of the first shell is allowed to extend out of the avoidance hole, thereby ensuring the reliability of the installation and use of the first shell.

[0044] like Figures 1 to 8As shown, the present application provides a cooking utensil, including a shell 10 and a cooking container arranged on the shell 10, a heating plate 12 is provided between the shell 10 and the cooking container, the heating plate 12 is provided with an avoidance hole 121, a detection component 13 is provided between the heating plate 12 and the shell 10, the detection component 13 includes a first shell 14, a temperature sensing element 15, a pressure ring 16, an elastic member 17 and a second shell 18, the first shell 14 has a accommodating cavity 141 with an opening facing downward, the pressure ring 16 moves along the side wall of the accommodating cavity 141 in a direction away from the opening under the action of the elastic member 17, so that the pressure ring 16 abuts the temperature sensing element 15 against the inner top wall of the accommodating cavity 141, the second shell 18 is fixed to the heating plate 12, at least part of the first shell 14 can extend from the avoidance hole 121, and the first shell 14 floats up and down along the avoidance hole 121 relative to the second shell 18 through the elastic member 17.

[0045] In the prior art, two elastic parts are used to respectively realize the assembly of the thermostat itself and the installation of the thermostat on the cooking utensil. The number of accessories is large, resulting in a complex structure and high cost. In order to solve this problem, the detection component 13 of the present application only needs one elastic part 17 to meet the assembly of the detection component 13 itself and the floating installation of the detection component 13. It uses fewer accessories, has a relatively simple structure, and is low in cost. Moreover, the use of the elastic part 17 to push against the temperature sensing element 15 can ensure that the temperature sensing element 15 is always in close contact with the first shell 14. At the same time, the first shell 14 can be in close contact with the cooking container due to the elastic force of the elastic part 17. Then, when the temperature is transferred from the cooking container to the first shell 14, and then from the first shell 14 to the temperature sensing element 15, the accuracy of the temperature detection can be guaranteed.

[0046] The cooking appliance of the present application can be a frying and roasting machine, an electric kettle, a health pot, etc., and the frying and roasting machine is used as an example for explanation. Figure 1 As shown, the grilling machine 20 includes a housing 10 and a cooking container detachably mounted on the housing 10, wherein the cooking container is a grilling pan 11. Figure 2 and Figure 6 As shown, the detection assembly 13 includes a first shell 14, a temperature sensing element 15, a pressure ring 16, an elastic member 17 and a second shell 18 from top to bottom. The detection assembly 13 is fixed to the heating plate 12 through the second shell 18 and the second shell 18 and the heating plate 12 axially limit the other components of the detection assembly 13 to achieve a firm installation of the detection assembly 13. The baking tray 11 is detachable and cleanable, which provides convenience for cleaning and improves the cleaning effect. When the user installs the baking tray 11, the baking tray 11 is placed down to press the top of the first shell 14 extending from the avoidance hole 121. At this time, the first shell 14 compresses the elastic member 17, which can make the elastic member 17 push the first shell 14 back to close to the baking tray 11, which is conducive to the timely transfer of heat from the baking tray 11 to the first shell 14, ensuring the heat transfer efficiency while providing favorable conditions for the accurate temperature measurement of the detection assembly 13.

[0047] As a preferred embodiment, the temperature sensing element 15 includes a horizontally extending temperature sensing portion 151 and a connecting portion 152 extending vertically below the temperature sensing portion 151. The top of the pressure ring 16 is provided with a receiving groove 161, and the side wall of the pressure ring 16 is provided with an avoidance recess 162. After the temperature sensing portion 151 is embedded in the receiving groove 161 and the connecting portion 152 is embedded in the avoidance recess 162, the pressure ring 16 moves along the side wall of the accommodating cavity 141 in a direction away from the opening.

[0048] like Figure 4 and Figure 8 As shown, the temperature sensing element 15 is arranged between the first shell 14 and the pressure ring 16. The top of the pressure ring 16 is provided with a receiving groove 161 that can accommodate the temperature sensing part 151 of the temperature sensing element 15. The temperature sensing part 151 is usually thin. When installing the temperature sensing element 15, if the temperature sensing element 15 is first installed into the receiving cavity 141 and then the pressure ring 16 is installed upward, it is easy for the receiving groove 161 of the pressure ring 16 to be difficult to align with the temperature sensing part 151. When an assembly error occurs, it will affect the pushing effect of the pressure ring 16 on the temperature sensing element 15, which is not conducive to making the temperature sensing element 15 evenly contact with the inner top wall of the receiving cavity 141, thereby affecting the temperature detection accuracy. In order to avoid the above situation, the present application first embeds the temperature sensing part 151 into the accommodating groove 161 and then installs the pressure ring 16 and the temperature sensing element 15 as a whole into the accommodating cavity 141. It can ensure that under the action of the elastic part 17, the pressure ring 16 evenly pushes the temperature sensing part 151 so that it is close to the inner top wall of the accommodating cavity 141, thereby ensuring the accuracy of temperature detection.

[0049] When the side wall of the pressure ring 16 is an arc-shaped wall, it is not conducive to the connection part 152 to be tightly attached to the side wall of the pressure ring 16, which makes the connection part 152 easy to deflect. By providing the avoidance recess 162, the installation position of the connection part 152 can be limited, which can improve the overall installation stability of the temperature sensing element 15 on the pressure ring 16.

[0050] In one embodiment, a through hole is provided at the bottom of the second housing 18 for the connecting portion 152 to pass through. Figure 3 and Figure 7 As shown, after the detection assembly 13 is installed, the lower end of the connecting portion 152 can extend from the through hole so as to be connected to the control board through an electric wire.

[0051] It is understandable that in other embodiments, the length of the connecting portion 152 may be shorter, and the connecting portion 152 may be pre-connected with wires, which extend from the through-holes to connect to the control board.

[0052] The detection component 13 of the present application can be assembled into an integral structure before being installed with the heating plate 12. Alternatively, it is not necessary to assemble the entire structure, but instead install the components in a certain order, which can be selected according to actual needs.

[0053] In one embodiment, one of the first shell 14 and the second shell 18 is provided with a limiting portion, and the other is provided with a matching portion that matches the limiting portion, so that the first shell 14 can be movably connected to the second shell 18.

[0054] like Figures 2 to 5 As shown, the first housing 14 and the second housing 18 are connected and together enclose the internal components, preventing the components from scattering during installation of the detection assembly 13, which could affect installation efficiency. Furthermore, the first housing 14 is movably connected to the second housing 18, allowing the first housing 14 to float after installation. This allows the user to press down on the first housing 14 when placing a cooking container. The first housing 14 compresses the elastic member 17, which provides an upward force that pushes the first housing 14 against the cooking container, thereby ensuring accurate temperature detection. The limiting portion and the mating portion connect the two housings, ensuring that the first housing 14 does not detach from the second housing 18.

[0055] In one embodiment, the limiting portion is a hook 142 provided on the first shell 14 and extending toward the second shell 18, and the matching portion is an assembly hole 181 provided on the second shell 18. The hook 142 has a first position of being hooked on the outer edge of the assembly hole 181 and a second position of sliding to below the assembly hole 181.

[0056] like Figure 5 As shown, after the detection component 13 is assembled, the hook 142 is stuck on the outer edge of the assembly hole 181, so that the detection component 13 forms an integral part. In this state, the elastic member 17 is in a compressed state, which can make the pressure ring 16 press the temperature sensing element 15 against the inner top wall of the accommodating cavity 141, so that the temperature sensing element 15 always maintains contact with the first shell 14. The hook 142 is an L-shaped structure including a vertical main body 1421 and a bent hook 1422 located at the bottom end of the main body 1421. When the baking tray 11 is installed, the baking tray 11 can press down the first shell 14 to move the first shell 14 downward. At this time, the hook 1422 is separated from the second shell 18, and the main body 1421 partially extends downward from the assembly hole 181 to form a shape as shown in FIG. Figure 3 Because the hook 1422 acts as a stop, the first housing 14 will not fall off the second housing 18 when the first housing 14 is reset upward, thus ensuring the connection between the two. In the embodiment with the assembly hole 181, the assembly hole 181 also serves as a through hole for the connecting portion 152 to extend, eliminating the need for a dedicated through hole and further simplifying the structure.

[0057] In other embodiments, the limiting portion and the matching portion may also be, for example, a guide rail and a slider structure, as long as the limiting and sliding functions of the first shell 14 can be achieved.

[0058] In another embodiment, when the first shell 14 is fixed to the heating plate 12 through the second shell 18 , the first shell 14 is sandwiched between the second shell 18 and the heating plate 12 .

[0059] like Figures 6 to 8 As shown, the detection component 13 does not need to be assembled into an integral structural component, but the components can be installed in a certain order. In this way, the structure for connection provided on the first shell 14 and the second shell 18 can be omitted, thereby simplifying the structure. Moreover, the method of clamping the first shell 14 by the second shell 18 and the heating plate 12 can ensure that the detection component 13 as a whole is firmly installed on the heating plate 12.

[0060] As a preferred embodiment, the pressure ring 16 has a pressure ring side wall 163 surrounding the upper end of the elastic member 17 to limit the radial displacement of the elastic member 17 and provide guidance for the axial movement of the elastic member 17 .

[0061] Without a certain limit, the elastic member 17 is prone to deflection during the axial movement, which is not conducive to the elastic force of the elastic member 17 being fully supplied to other components, affecting the contact effect between the temperature sensing element 15 and the inner top wall of the accommodating cavity 141 or the first shell 14 and the cooking container. Figure 2 and Figure 6 As shown, the present application arranges the pressure ring side wall 163 around the upper end of the elastic member 17, which can prevent the elastic member 17 from swinging to a large extent and provide movement guidance for the elastic member 17.

[0062] As a preferred embodiment, the bottom wall of the second shell 18 is provided with a positioning column 182 extending upward, and the lower end of the elastic member 17 is sleeved on the positioning column 182 .

[0063] like Figure 3 and Figure 7 As shown, in order to prevent the elastic member 17 from moving in the axial direction and affecting the pushing effect of the elastic member 17 on the pressure ring 16, the bottom wall of the second housing 18 is provided with an upwardly extending positioning column 182, which can realize the axial limitation of the elastic member 17. The elastic member 17 of the present application is a spring.

[0064] As a preferred embodiment, the second shell 18 has a shell side wall extending upward and a flange portion 183 extending outward from the top of the shell side wall. The flange portion 183 is provided with a screw hole 184. The heating plate 12 is provided with a screw column 122 extending downward and corresponding to the screw hole 184. Figure 4 and Figure 8 As shown, the second housing 18 is fixed to the heating plate 12 by screws 19 to realize the installation of the detection component 13, which has a simple structure and a secure installation. The detection component 13 can be disassembled for inspection and maintenance.

[0065] As a preferred embodiment, a step portion 143 extending radially outward is provided at the bottom end of the side wall of the accommodating cavity 141. The outer diameter of the step portion 143 is larger than the diameter of the avoidance hole 121. The step portion 143 is used to limit the distance that the first shell 14 moves upward along the avoidance hole 121.

[0066] When the first housing 14 is not connected to the second housing 18, as in Figure 7 In this solution, to prevent the first housing 14 from completely slipping out of the escape hole 121 during its upward floating process, the distance the first housing 14 can move upward needs to be limited. By providing a step portion 143 with an outer diameter larger than the diameter of the escape hole 121, the step portion 143 can be positioned below the escape hole 121, allowing only a portion of the first housing 14 to extend out of the escape hole 121, thereby ensuring reliable installation and use of the first housing 14. Furthermore, during installation of the detection assembly 13, the step portion 143 prevents the first housing 14 from slipping out of the escape hole 121.

[0067] Of course, in Figure 3 In the solution, a step portion 143 may also be provided to prevent the first shell 14 from completely popping out of the avoidance hole 121 when the hook 142 fails to limit the position, thereby affecting the reliability of use.

[0068] The technical solutions protected by this utility model are not limited to the above-described embodiments. It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the above description of this utility model has been provided in detail using general instructions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
