Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in this specification in order not to obscure the core of the present application with unnecessary detail, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

The application provides a cooking heating device capable of heating a cooking appliance to cook food, and the cooking heating device can comprise but is not limited to an electromagnetic oven, an electric ceramic oven, a gas stove, a mixed stove and other devices capable of heating the cooking appliance. The cooking appliance may be used to hold food materials, which may include, but is not limited to, various pots, grills, and other appliances.

Referring to fig. 1-3, in some embodiments, the cooking heating apparatus is illustrated as an induction cooker 1, but in other embodiments, the cooking heating apparatus may be other cooking heating apparatuses such as an electric ceramic stove, a gas stove, and a mixing range.

Referring to fig. 1-3, in some embodiments, the induction cooker 1 includes a housing 100, a heating element (not shown), and a temperature measuring element 200, but the induction cooker 1 may also include other related components, such as a control unit (not shown) for controlling the heating element and the temperature measuring element 200. These relevant components can be referred to the existing induction cooker 1.

The housing 100 has a mounting cavity 101, and the heating assembly, the temperature measuring assembly 200, the control unit and other components can be mounted in the mounting cavity 101, so that the appearance of the induction cooker 1 is more concise. The housing 100 is typically formed from two or more sub-components that are joined together. This heating element is located in installation cavity 101 for heat cooking utensil.

The heating component of the induction cooker 1 can realize heating by adopting the electromagnetic induction principle. For example, the heating assembly uses alternating current to pass through the coil to generate a changing alternating magnetic field, eddy current can be generated in the cooking utensil in the alternating magnetic field, and the joule effect of the eddy current can increase the temperature of the conductor, so that heating is realized. Of course, in other types of cooking and heating devices, the heating assembly may take other forms for heating, such as a heating assembly of an electric ceramic stove, a gas range, or a hybrid range.

Referring to fig. 1-3, in some embodiments, the housing 100 includes a panel 110. In some embodiments, the heating assembly may be disposed directly below the panel 110 to heat the cooking appliance on the panel 110. The panel 110 is used to support a cooking utensil and is heated by a heating assembly. Of course, in other cooking and heating devices, such as a gas range, the panel 110 may be only a part of the housing 100 and is not used for supporting the cooking utensil. The panel 110 may be made of various panel materials and structures commonly used in cooking heating apparatuses, for example, the panel 110 may be made of glass, ceramic, etc.

Referring to fig. 1-3, in some embodiments, the panel 110 has a first through hole 111, and the first through hole 111 is used for accommodating the temperature measuring assembly 200. Referring to fig. 4 and fig. 7-9, in some embodiments, the temperature measuring assembly 200 has a temperature measuring head 210 and a supporting base 220, the temperature measuring head 210 has a temperature measuring sensor (not shown), and the temperature measuring sensor can be selected from various structures capable of measuring temperature, such as a thermistor, a thermocouple, or other types of sensors. The temperature measuring head 210 extends out of the panel 110 from the first through hole 111 to measure the temperature of the cooking appliance. The support base 220 is connected to the case 100, and the support base 220 forms a floating support for the temperature measuring head 210, so that the temperature measuring head 210 can move toward the inside of the case 100 under the pressure of the cooking appliance. The floating support is usually an elastic support, and the structure of the floating support provides a supporting force to the temperature measuring head 210, so that the temperature measuring head 210 can keep a state of extending out of the panel 110 from the first through hole 111 in a normal state. When the cooking appliance is placed on the panel 110, the cooking appliance presses down the temperature measuring head 210, causing the temperature measuring head 210 to retract inward. This floating support's structure can make cooking utensil when placing panel 110, temperature probe 210 can keep keeping inseparable contact with cooking utensil under floating support's structure to guarantee that the temperature measurement result is more accurate.

Referring to fig. 4, 9 and 10, in some embodiments, the peripheral outer wall of the thermal probe 210 is formed with a liquid discharge channel 301 (as indicated by the dotted arrow), and the thermal probe 210 can move in the liquid discharge channel 301. The liquid discharge channel 301 at least partially surrounds the peripheral outer wall of the temperature probe 210, wherein the peripheral outer wall of the temperature probe 210 forms at least a portion of the channel wall of the liquid discharge channel 301. This flowing back passageway 301 is used for guaranteeing on the one hand that temperature probe 210 can move relative to panel 110, and this flowing back passageway 301 has inlet 302 and liquid outlet 303 that communicate each other on the other hand, and inlet 302 is higher than liquid outlet 303 to make the liquid that gets into from inlet 302 can discharge to the outside of casing 100 from liquid outlet 303. In order to prevent liquid from entering into the installation cavity 101, in some embodiments, the liquid drainage channel 301 is sealed from the installation cavity 101 to prevent the liquid from entering into the installation cavity 101 from the liquid drainage channel 301 to damage components in the installation cavity 101, and particularly to prevent damage to electrical devices in the installation cavity 101, which may include, but are not limited to, a control unit, a heating assembly, a load cell, a speaker, an antenna, and the like.

At least a part of the drainage channel 301 can be formed by enclosing the temperature measuring head 210 and other components. The other component may be a component in the temperature measuring assembly 200 except for the temperature measuring head 210, or may be a component in the cooking heating apparatus except for the temperature measuring assembly 200.

Referring to fig. 4 and fig. 8 and 9, in some embodiments, the support base 220 defines a floating cavity 223 having a thermal head protrusion 2223. The thermal probe 210 has a first portion 201 and a second portion 202, and the second portion 202 is located in the floating cavity 223 and floatingly connected to the support base 220. The first portion 201 extends from the extension port 2223 of the temperature measuring head into the first through hole 111 of the panel 110, and forms a first gap 304 with the wall of the first through hole 111. The second portion 202 forms a second gap 305 with the walls of the floating cavity 223. Wherein the first gap 304 communicates with the second gap 305 to form at least a part of the liquid discharge channel 301. Of course, in some embodiments, the first gap 304 and the second gap 305 may directly form the entire liquid discharge channel 301.

Referring to fig. 8 and 9, in some embodiments, in order to enable the supporting base 220 to form the second gap 305 with the thermal probe 210 and ensure that the thermal probe 210 can move smoothly relative to the supporting base 220, in some embodiments, a plurality of protrusions 2224 facing the thermal probe 210 are disposed on a wall of the thermal probe extension opening 2223 of the supporting base 220, and the protrusions 2224 can limit the thermal probe 210 to ensure that the thermal probe moves according to a specific track. The protrusions 2224 are provided with a gap therebetween, which is used to form the second gap 305.

Of course, the drainage channel 301 may be formed by other structures in other embodiments. Referring to fig. 10, in some embodiments, the supporting base 220 is inserted into and hermetically mounted in the first through hole 111 of the panel 110. At this time, the supporting base 220 is connected to the panel 110 in a sealing and fixing manner, wherein since there is no need to implement a relative movement between the supporting base 220 and the panel 110, a sealing and fixing structure can be implemented more easily, for example, a sealing ring can be used for sealing, and there is no need to leave a gap between the supporting base 220 and the panel 110.

Referring to fig. 10, in some embodiments, the supporting base 220 defines a floating cavity 223 having a temperature probe extending opening 2223, the temperature probe 210 has a first portion 201 and a second portion 202, the second portion 202 is located in the floating cavity 223 and is connected to the supporting base 220 in a floating manner, and the first portion 201 extends from the temperature probe extending opening 2223. At least one part of the liquid discharge channel 301 is enclosed by the temperature measuring head 210 and the supporting seat 220.

In addition, in addition to the structure of forming the liquid discharge channel 301 shown in the above embodiments, in other embodiments, the liquid discharge channel 301 may be formed by other structures.

Further, in order to prevent the drainage channel 301 from communicating with the mounting cavity 101, referring to fig. 4 and fig. 7-9, in some embodiments, the supporting base 220 is hermetically connected to the inner side of the panel 110, so that a sealing structure is formed between the supporting base 220 and the panel 110 to hermetically separate the first gap 304 and the second gap 305 from the mounting cavity 101. In addition, the support base 220 is connected with the panel 110 in a sealing manner, and the drainage channel 301 can also form an independent sealing structure, so that liquid can leak from the drainage channel 301 to other spaces of the equipment. The supporting base 220 and the panel 110 can be fixedly connected by bonding, welding, clamping, screwing or other methods. To achieve or enhance the sealing effect, a sealing member may be disposed between the supporting seat 220 and the panel 110 to enhance the sealing effect.

Referring to fig. 4 and fig. 7-9, in some embodiments, the supporting base 220 has a connecting portion 2221 surrounding the liquid drainage channel 301, and the supporting base 220 is fixedly connected to the panel 110 by the connecting portion 2221. The connection portion 2221 is disposed around the liquid discharge passage 301, and when it is hermetically connected to the panel 110, it is ensured that the liquid does not leak around the liquid discharge passage 301.

Further, referring to fig. 4 and fig. 7-9, in some embodiments, the connection portion 2221 may be designed to be a disk or other plate-shaped structure to increase a contact surface with the panel 110, so as to improve a sealing effect between the connection portion 2221 and the panel 110. In particular, when the connection portion 2221 is adhered or welded to the panel 110, increasing the contact surface of the connection portion 2221 is more advantageous for the adhesion and welding effects.

Further, referring to fig. 4 and fig. 7-9, in some embodiments, the connection portion 2221 is fixed to the panel 110 by adhesion, which not only achieves a fixed connection, but also achieves a sealing effect.

Referring to fig. 4 and fig. 7-9, in some embodiments, in order to achieve better adhesion, a ring of concave glue-receiving grooves 2222 is formed on a surface of the connecting portion 2221 facing the panel 110. The glue containing slot 2222 is filled with glue, and the connection portion 2221 and the panel 110 are fixed by gluing with the glue. The glue groove 2222 is recessed towards the inner side of the connecting portion 2221 (the inner side of the connecting portion 2221 shown in the figure is the lower side of the connecting portion 2221 shown in the figure), and the groove wall of the glue groove 2222 is raised to prevent the glue solution from flowing outwards, especially to prevent the glue solution from flowing into the first gap 304 and the second gap 305.

Further, referring to fig. 4 and fig. 7-9, in some embodiments, the glue receiving groove 2222 is an annular structure at least partially surrounding the liquid discharge channel 301 and the temperature measuring head 210, so as to form an adhesive surface surrounding the liquid discharge channel 301 and the temperature measuring head 210, thereby improving the fixing structure of the supporting base 220 and the panel 110.
