Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cooking utensil. Background Art

[0002] Cooking appliances such as induction cookers have the advantages of fast heating, no open flame, safety and convenience, and are increasingly favored and recognized by consumers. The induction cooker includes a bearing plate, a shell and a heating structure, the bearing plate is arranged on the top of the shell, the bearing plate and the shell enclose a cavity, and the heating structure is located in the cavity.

[0003] The load plate is a key component of the induction cooker, which supports the pot.

After the load plate breaks, the liquid in the pot spills on the load plate and easily enters the inside of the shell. The liquid flows into the heating structure, power cord and other conductive parts in the shell, which is likely to cause safety hazards. Utility Model Content

[0017] The glue gap can be used to accommodate sealant. During the assembly process of the insulation sheet, the sealant can be used to fill the gap so that the insulation sheet and the installation port are sealed and connected by the sealant. In addition, the glue gap can also provide an installation gap for the insulation sheet to improve the convenience of installation of the insulation sheet.

[0018] According to one embodiment of the present application, the housing has a mounting recess, the mounting port is arranged on the bottom surface of the mounting recess, along the thickness direction of the supporting plate, the supporting plate is located between the bottom surface and the heating structure, and the supporting plate covers the bottom surface.

[0021] The depth of the mounting recess is equal to the thickness of the carrying plate.

[0022] After the insulating sheet is sealed and connected to the mounting opening, the surface of the insulating sheet facing the bearing plate can be flush with the surface of the mounting recess facing the bearing plate, so as to improve the flatness of the mounting of the bearing plate.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0060] Induction cookers, electric ceramic cookers, electric pressure cookers, etc. are commonly used cooking utensils, and the cooking utensils include a carrying plate, a shell and a heating structure. The carrying plate and the shell can enclose a relatively closed cavity to shield the internal power board, control board, heating structure and other live parts during the working process. Among them, the control board is electrically connected to the heating structure to control the opening and closing of the heating structure through the control board. The heating structure can be an electromagnetic coil. When working, high-frequency current passes through the heating structure to generate countless closed magnetic field forces. Magnetic lines of force cutting the pot can generate countless small eddy currents to heat the pot placed on the carrying plate. When in use, the pot is placed on the carrying plate of the cooking utensil. The cooking utensil can be used to cook the ingredients in the pot.

[0061] The support plate supports the pot and is a key component of the cooking utensil. When the user uses the cooking utensil to heat the pot, the pot may sometimes dry burn, and the temperature at the bottom of the pot is relatively high. Therefore, when the pot is placed on the support plate, it is easy for the support plate to break. After the support plate breaks, the liquid in the pot spills on the support plate and easily flows into the inner part of the shell. The liquid flows into the heating structure, power cord and other conductive parts in the shell, which is easy to cause safety hazards.

[0062] Cooking utensils need to undergo safety tests before leaving the factory. Safety tests for cooking utensils usually test insulation and water resistance. If the carrier plate is broken, it will be difficult to meet safety requirements, especially when the carrier plate is made of low-cost materials. For example, when the carrier plate is made of ceramic material, since the ceramic material carrier plate has a large porosity, its strength is reduced. When conducting a water overflow pressure test, it is easy to cause the carrier plate to break, and the liquid will flow into the conductive parts in the shell, which can easily affect the working performance of the conductive parts and cause damage to the conductive parts. On the other hand, it is also easy to cause safety hazards.

[0063] Based on the above technical problems, the applicant has improved the structure of the existing cooking utensils. In the present application, an insulating sheet is provided between the heating structure and the outer shell. The insulating sheet has insulation, pressure resistance and waterproof properties, and can be used to meet the safety test of the cooking utensils. The insulation of the insulating sheet can be used to block the conductive parts in the outer shell, and avoid the problem of internal conductive parts being exposed and causing safety hazards after the supporting plate is broken. In addition, the possibility of liquid flowing into the internal conductive parts through the mounting port after the supporting plate is broken can be reduced by sealing the mounting port of the insulating sheet and the outer shell. The pressure resistance of the insulating sheet can assist in supporting the pot after the supporting plate is broken.

[0064] When a load-bearing plate made of a relatively low-cost material is used, in order to meet the basic load-bearing capacity and comply with the impact test of the cookware, the thickness of the load-bearing plate itself increases, and the distance between the heating structure and the cookware also increases. Therefore, in order to avoid the increase in the distance between the heating structure and the cookware, which affects the heating power and energy efficiency of the cooking utensil on the cookware, the installation height of the heating structure also needs to be increased. The present application provides a thickness of an insulating sheet so that when the distance between the heating structure and the insulating sheet is less than 2 mm, the safety test of the cooking utensil can be met. The thickness of the insulating sheet is greater than or equal to 2 mm and less than or equal to 5 mm.

[0065] The cooking appliance provided in the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0066] See also Figures 1 to 4 As shown, the cooking appliance 100 according to the embodiment of the present application includes a housing 110 , a heating structure 120 , a carrying plate 130 and an insulating sheet 140 .

[0067] See also Figure 3 and Figure 4 , a mounting opening 110a is provided on the housing 110. The heating structure 120 is provided inside the housing 110 and corresponds to the mounting opening 110a. The carrying plate 130 is located at the mounting opening 110a. The insulating sheet 140 can be located between the heating structure 120 and the carrying plate 130. The insulating sheet 140 is sealed and connected to the mounting opening 110a. Along the thickness direction Z of the carrying plate 130, the distance k between the insulating sheet 140 and the heating structure 120 is less than 2 mm, and the thickness of the insulating sheet 140 is greater than or equal to 2 mm and less than or equal to 5 mm.

[0068] Among them, the distance k between the insulating sheet 140 and the heating structure 120 can be understood as an insulating distance. That is, the greater the distance between the insulating sheet 140 and the heating structure 120, the less likely it is that the bearing plate 130 will contact the internal heating structure 120 when it is broken down. The smaller the distance k between the insulating sheet 140 and the heating structure 120, the easier it is that the bearing plate 130 will contact the internal heating structure 120 and conduct electricity when it is broken down. Therefore, in an embodiment of the present application, when the distance k between the insulating sheet 140 and the heating structure 120 is less than 2 mm, setting the thickness of the insulating sheet 140 to be greater than or equal to 2 mm and less than or equal to 5 mm can meet safety test.

[0069] When the distance k between the insulating sheet 140 and the heating structure 120 is small, the insulating sheet 140 needs to have a larger thickness to isolate the internal heating structure 120 through the insulating sheet 140, thereby meeting the safety test. For example, when the distance k between the insulating sheet 140 and the heating structure 120 is less than 1 mm, the thickness of the insulating sheet 140 can be 3 mm, 4 mm or 5 mm.

[0070] Similarly, when the distance k between the insulating sheet 140 and the heating structure 120 is larger, the insulating sheet 140 may have a smaller thickness. For example, when the distance k between the insulating sheet 140 and the heating structure 120 is close to 2 mm, the thickness of the insulating sheet 140 may be 2 mm.

[0071] In some examples, the insulating sheet 140 in the embodiment of the present application can pass the 3000V withstand voltage test. Therefore, when the safety test is met, the thickness of the insulating sheet 140 can be set as small as possible to reduce the material cost of the insulating sheet 140, thereby helping to reduce the total cost of the cooking appliance 100. For example, the thickness of the insulating sheet 140 can preferably be 2 mm.

[0072] In some examples, the insulating sheet 140 of the present application may be, but is not limited to, a mica sheet. Mica sheets have good insulation, pressure resistance, and waterproof properties, and are relatively low in cost.

[0073] In some possible implementations, see Figures 4 to 6 As shown, the inner wall 110 b of the mounting opening 110 a of the embodiment of the present application may be provided with a support plate 111 . The insulating sheet 140 is disposed on a surface of the support plate 111 facing the carrier plate 130 .

[0074] The support plate 111 of the embodiment of the present application may protrude from the inner wall 110 b of the installation opening 110 a , and the support plate 111 may have a surface facing the carrier plate 130 for supporting the insulating sheet 140 .

[0075] The surface of the support plate 111 facing the carrier plate 130 is a plane to maintain the installation flatness of the insulating sheet 140. The shape of the support plate 111 is not limited in this embodiment.

[0076] In some possible implementations, see Figure 6 As shown, the inner wall 110b of the mounting opening 110a of the embodiment of the present application may also be provided with a positioning protrusion 100a. A positioning recess 100b may be provided on the insulating sheet 140. The positioning protrusion 100a corresponds to the positioning recess 100b. The positioning protrusion 100a and the positioning recess 100b may be matched and connected.

[0077] In some examples, the positioning protrusion 100a of the embodiment of the present application can protrude from the inner wall 110b of the installation opening 110a. When the insulating sheet 140 is placed on the support plate 111, the positioning concave portion 100b on the insulating sheet 140 can correspond to the positioning protrusion 100a on the installation opening 110a to preliminarily position the insulating sheet 140.

[0078] In some examples, the positioning protrusion 100a can be disposed on one of the inner walls 110b of the installation opening 110a, so that the insulating sheet 140 can have a fixed installation direction by cooperating with the positioning protrusion 100a and the positioning recess 100b. The positioning protrusion 100a and the positioning recess 100b can realize the anti-mistake installation of the insulating sheet 140, and prevent the insulating sheet 140 from being installed upside down and affecting the working performance of the cooking utensil 100. Specifically, when the direction of the insulating sheet 140 is placed incorrectly, the insulating sheet 140 cannot be installed flatly on the support plate 111, and the installation direction of the insulating sheet 140 needs to be readjusted.

[0079] In other examples, the inner wall 110b of the installation opening 110a may be provided with a positioning recess, and the insulating sheet 140 may be provided with a positioning protrusion, which is cooperatively connected with the positioning recess.

[0080] In some examples, there may be an installation gap between the positioning protrusion 100 a and the positioning recess 100 b to facilitate installation of the insulating sheet 140 on the support plate 111 .

[0081] In some possible implementations, see Figure 5 and Figure 7 As shown, there may be a glue gap 100c between the outer edge of the insulating sheet 140 and the inner wall 110b of the mounting opening 110a. The glue gap 100c may be used to accommodate sealant, which is used to seal the insulating sheet 140 and the mounting opening 110a.

[0082] When the positioning concave portion 100b of the insulating sheet 140 corresponds to the positioning convex portion 100a of the mounting opening 110a, a gluing gap 100c may be provided between the outer edge of the insulating sheet 140 and the inner wall 110b of the mounting opening 110a. The gluing gap 100c may be used to accommodate sealant. During the assembly process of the insulating sheet 140, a sealant may be used to fill the gap so that the insulating sheet 140 is sealed and connected to the mounting opening 110a through the sealant. In addition, the gluing gap 100c may also provide an installation gap for the insulating sheet 140 to improve the convenience of installation of the insulating sheet 140.

[0083] Specifically, the sealant of the embodiment of the present application can seal the gap between the insulating sheet 140 and the mounting opening 110a to reduce the possibility of liquid flowing into the conductive components inside the housing 110 through the gap between the insulating sheet 140 and the mounting opening 110a when the supporting plate 130 is broken.

[0084] In some examples, the sealant may also have the function of fixing the insulating sheet 140. The sealant may fix the insulating sheet 140 to the support plate 111, thereby reducing the possibility that the insulating sheet 140 moves and affects the sealing effect at the gap.

[0085] In some examples, the sealant of this embodiment may be, but is not limited to, silicone sealant.

[0086] In some possible implementations, see Figure 8 and Fig. 9 As shown, the housing 110 may have a mounting recess 112. The mounting opening 110a may be disposed on the bottom surface of the mounting recess 112. Along the thickness direction Z of the carrier plate 130, the support plate 111 may be located between the bottom surface and the heating structure 120. The carrier plate 130 may cover the bottom surface.

[0087] The mounting recess 112 of the embodiment of the present application can be used to mount the carrier plate 130. When the insulating sheet 140 is sealed and connected to the mounting opening 110a, the carrier plate 130 can cover the mounting recess 112 and be sealed and connected to the mounting recess 112.

[0088] In some examples, the support plate 111 may be located inside the mounting recess 112 . That is, along the thickness direction Z of the carrier plate 130 , the orthographic projection of the support plate 111 may be located inside the orthographic projection of the mounting recess 112 .

[0089] In some possible implementations, see Figure 8 and Fig. 9 As shown, along the thickness direction Z of the carrier plate 130 , a distance p between the surface of the support plate 111 facing the carrier plate 130 and the bottom surface of the mounting recess 112 may be equal to the thickness of the insulating sheet 140 .

[0090] In the embodiment of the present application, after the insulating sheet 140 is sealed and connected to the mounting opening 110a, the surface of the insulating sheet 140 facing the carrier plate 130 can be flush with the surface of the mounting recess 112 facing the carrier plate 130 to improve the flatness of the mounting of the carrier plate 130.

[0091] In some achievable embodiments, the depth q of the mounting recess 112 may be equal to the thickness of the carrier plate 130 .

[0092] After the carrying plate 130 is installed in the installation recess 112 , the surface of the carrying plate 130 away from the heating structure 120 can be flush with the outer surface of the housing 110 , so as to improve the aesthetics of the cooking appliance 100 .

[0093] In some examples, the mounting opening 110a of the housing 110 may be a square hole. The carrying plate 130 may be a square structure, which is not limited in this embodiment.

[0094] In some possible implementations, see Figure 6 and Fig.10As shown, the mounting recess 112 of the embodiment of the present application may be provided with a glue groove 112a and a glue overflow groove 112b. The glue groove 112a and the glue overflow groove 112b may be recessed toward the heating structure 120. The glue overflow groove 112b is located outside the glue groove 112a.

[0095] The glue groove 112a and the overflow glue groove 112b of the embodiment of the present application can be located on the surface of the mounting recess 112 facing the carrier plate 130. Among them, the glue groove 112a can be used to accommodate the connecting glue. The connecting glue has fluidity. In order to improve the connection reliability between the carrier plate 130 and the mounting recess 112, when gluing, the connecting glue located in the glue groove 112a can protrude from the surface of the mounting recess 112 facing the carrier plate 130. The overflow glue groove 112b can be used to accommodate the connecting glue overflowing from the glue groove 112a. When the carrier plate 130 is placed on the second mounting surface, the carrier plate 130 can press the excess connecting glue into the overflow glue groove 112b. The connecting glue in the overflow glue groove 112b can be used to increase the contact area between the carrier plate 130 and the mounting recess 112 to improve the connection stability between the two.

[0096] In addition, the excess connecting glue flowing into the glue overflow groove 112b can also reduce the possibility that, after the connecting glue is cured, part of the connecting glue protrudes from the surface of the mounting recess 112 facing the carrier plate 130, resulting in uneven installation of the carrier plate 130. It can also reduce the possibility that part of the connecting glue protrudes from the surface of the mounting recess 112, thereby affecting the sealing effect between the carrier plate 130 and the outer shell 110.

[0097] In some examples, the glue groove 112a and the glue overflow groove 112b can both be closed annular grooves. The glue groove 112a can be arranged along the outer side of the installation opening 110a. The glue overflow groove 112b can be arranged along the outer side of the glue groove 112a.

[0098] In some possible implementations, see Figure 3 , Figure 4 and Fig.11 As shown, the cooking appliance 100 of the embodiment of the present application may further include a temperature sensor 150. The temperature sensor 150 may be disposed in the central area of ​​the heating structure 120. The temperature sensor 150 may include a sensor body 151. A through hole 140a may be provided on the insulating sheet 140, and one end of the sensor body 151 may pass through the through hole 140a to abut against the surface of the carrier plate 130 facing the heating structure 120.

[0099] The temperature sensor 150 of the embodiment of the present application can be used to measure the temperature on the carrier plate 130 to control the heat provided to the pot by the cooking utensil 100 through the control panel. One end of the sensor body 151 directly abuts against the carrier plate 130, thereby improving the accuracy of the temperature sensor 150 in monitoring the temperature.

[0100] In some examples, the temperature sensor 150 of the embodiments of the present application may be located at the center of the heating structure 120 .

[0101] In some possible implementations, see Figure 3 and Fig.11 As shown, along the thickness direction Z of the carrier plate 130 , the end of the sensor body 151 facing the carrier plate 130 may be provided with a contact head 1511 . The contact head 1511 may pass through the through hole 140 a to be connected to the carrier plate 130 , and may be interference fit with the carrier plate 130 .

[0102] The interference fit between the contact head 1511 and the carrier plate 130 in the embodiment of the present application can enable the contact head 1511 to maintain contact with the carrier plate 130 , thereby improving the accuracy of the temperature sensor 150 in measuring temperature.

[0103] Along the thickness direction Z of the carrier plate 130 , the interference m between the contact head 1511 and the carrier plate 130 may be greater than or equal to 1.5 mm and less than or equal to 4 mm. For example, the interference m between the contact head 1511 and the carrier plate 130 may be 2.5 mm.

[0104] It can be understood that, since the contact head 1511 of the sensor body 151 passes through the through hole 140 a on the insulating sheet 140 , the size of the through hole 140 a on the insulating sheet 140 is greater than or equal to the size of the contact head 1511 .

[0105] In some examples, the size of the through hole 140a on the insulating sheet 140 may be greater than or equal to 5 mm and less than or equal to 30 mm. For example, the size of the through hole 140a may be 10 mm.

[0106] In some possible implementations, see Figure 3 and Fig.11 As shown, the temperature sensor 150 may further include a silicone member 152. The silicone member 152 may be sleeved on the outside of the sensor body 151. The silicone member 152 may be provided with a central protrusion 152a facing the carrier plate 130. The central protrusion 152a may support the contact head 1511. The central protrusion 152a passes through the through hole 140a so that the contact head 1511 abuts against the carrier plate 130.

[0107] The silicone member 152 of the embodiment of the present application can isolate the heating structure 120 and the sensor body 151 to reduce the effect of the heating structure 120 heating on the sensor body 151. In addition, the silicone member 152 can produce elastic deformation. The insulating sheet 140 can press the silicone member 152, and the silicone member 152 produces compression deformation to seal the through hole 140a.

[0108] The central protrusion 152a of the silicone member 152 can be used to support the contact head 1511, and the central protrusion 152a can produce elastic deformation. When the contact head 1511 and the carrier plate 130 are interference fit, the central protrusion 152a can produce compression deformation so that the contact head 1511 can keep pressing against the carrier plate 130. In addition, the pressure on the central protrusion 152a can also reduce the pressure on the panel caused by the contact head 1511, thereby reducing the possibility of deformation or wear of the carrier plate 130 caused by the force.

[0109] In some possible implementations, see Figure 3 and Fig.11 As shown, the silicone member 152 of the embodiment of the present application may also be provided with an end surface 152b facing the carrier plate 130. The central protrusion 152a may protrude from the end surface 152b. The end surface 152b may also be provided with a waterproof protrusion 1521. The waterproof protrusion 1521 may be pressed between the insulating sheet 140 and the end surface 152b to seal the through hole 140a.

[0110] In this embodiment, the waterproof protrusion 1521 of the silicone member 152 can be interference fit with the surface of the insulating sheet 140 facing the heating structure 120. The waterproof protrusion 1521 can generate compression deformation between the insulating sheet 140 and the heating structure 120 to achieve sealing of the through hole 140a on the insulating sheet 140, so that liquid is not easy to enter the housing 110 through the through hole 140a.

[0111] In some examples, the waterproof protrusion 1521 can be a closed annular structure. The waterproof protrusion 1521 can be located outside the through hole 140a. When the carrier plate 130 is broken, the liquid falls on the insulating sheet 140, and the silicone member 152 is correspondingly arranged below the through hole 140a, so the liquid can fall on the silicone member 152 through the through hole 140a. However, since the waterproof protrusion 1521 is located outside the through hole 140a, that is, the inner diameter of the waterproof protrusion 1521 is larger than the diameter of the through hole 140a, the waterproof protrusion 1521 can prevent the liquid from diffusing outward and entering the housing 110 to achieve sealing of the through hole 140a.

[0112] In some examples, the interference n between the waterproof protrusion 1521 and the insulating sheet 140 may be greater than or equal to 0.4 mm and less than or equal to 1 mm. For example, the interference n between the waterproof protrusion 1521 and the insulating sheet 140 may be 0.8 mm.

[0113] In some achievable embodiments, the carrier plate 130 of the embodiment of the present application may be a carrier plate 130 made of a ceramic material.

[0114] The surface of the carrier plate 130 formed by grinding the microcrystalline glass is smooth and aesthetically pleasing. The microcrystalline glass carrier plate has good thermal stability, high insulation, and good chemical corrosion resistance and wear resistance. However, the cost of the carrier plate made of microcrystalline glass is high, resulting in a high overall cost of the cooking utensil 100. Therefore, the carrier plate 130 of this embodiment can be made of a ceramic material with a lower cost, and the cooking utensil 100 can meet safety tests through the insulating sheet 140, thereby reducing costs.

[0115] In some achievable embodiments, the thickness of the ceramic material support plate 130 may be greater than or equal to 4.5 mm and less than or equal to 8 mm.

[0116] The thickness of the ceramic material bearing plate of the embodiment of the present application can be larger to meet the cookware impact test. The thickness of the ceramic bearing plate of the present embodiment can be 6.5 mm.
