In existing technology, the multi-functional heater arranges the electric cooking function component in the upper part of the appliance and the heating function component in the lower part of the appliance, combining the whole into the form of a table or coffee table.

[0003] However, in the existing structure, the upper and middle parts of the appliance are usually enclosed. The heating components used for cooking continuously generate heat, causing heat to accumulate in the upper and middle parts of the appliance and not dissipate. This internal heat buildup poses a safety hazard. Utility Model Content

[0004] The main purpose of this utility model is to propose a multi-functional heater, which aims to solve the problem that the components used in the cooking function of existing multi-functional heaters continuously generate heat, causing the accumulated heat inside the appliance to be difficult to dissipate, thus posing a safety hazard. It also facilitates the dissipation of heat by the heating components used for heating.

[0005] To achieve the above objectives, the present invention proposes a multifunctional heater, comprising:

[0006] The main body has a heating platform formed at its upper end and a heating side formed on its side.

[0007] A first heating device, disposed within the main body and corresponding to the heating platform, is used to heat the heating appliance placed on the heating platform; and

[0008] The second heating device is disposed inside the main body and corresponding to the heating side, for radiating heat to the surrounding area of ​​the heating side;

[0009] An air duct is formed inside the main body. The air duct has an air inlet and an air outlet formed on the surface of the main body. The air outlet is formed on the heating side. The air duct is connected to the space where the first heating device is located inside the main body. A fan is installed inside the air duct. The fan is used to drive airflow to enter from the air inlet of the air duct and blow it out from the air outlet.

[0010] In one embodiment, a mounting cavity for mounting the first heating device is formed within the main body, and the mounting cavity constitutes at least a section of the air duct.

[0011] In one embodiment, the air duct further includes an air inlet duct that extends in a vertical direction, with the air inlet located at the lower end of the main body and the upper end of the air inlet duct communicating with the mounting cavity.

[0012] The fan is located in the air inlet duct.

[0013] In one embodiment, a side cavity is formed on the side of the main body, and an opening is provided on the outer side wall of the side cavity;

[0014] The second heating device is installed in the side cavity, and the side cavity is in communication with the mounting cavity;

[0015] The air duct also includes the side cavity, and the air outlet includes the opening.

[0016] In one embodiment, the side cavity is arranged in a ring shape along the circumference of the body;

[0017] The second heating device is arranged in a ring.

[0018] In one embodiment, the second heating device includes a heating element;

[0019] The side cavity has a reflective portion, which is located on the side of the heating element opposite to the opening.

[0020] In one embodiment, the reflective portion is gradually recessed from both the top and bottom ends toward the middle; and / or,

[0021] The reflective part is arranged in a ring.

[0022] In one embodiment, a partition is formed inside the main body to space between the air inlet duct and the mounting cavity, and the air outlet of the air inlet duct is formed on the partition;

[0023] The first heating device is elastically mounted on the upper side of the partition via an elastic element.

[0024] In one embodiment, the fan is fixedly connected to the lower side of the partition.

[0025] In one embodiment, the multifunctional heater further includes a support assembly, which includes a support base and a plurality of support members. The upper end of the support base is connected to the lower end of the main body, and the plurality of support members are disposed at the lower end of the support base.

[0026] In this invention, to prevent heat generated by the first heating device from accumulating inside the main body, an air inlet and an air outlet are provided on the surface of the main body, and an air duct is formed inside the main body, connecting to the space where the first heating device is located. Thus, a fan installed within the air duct drives airflow into the air inlet, which carries away the heat accumulated inside the main body from the first heating device, and the airflow exits through the air outlet. Furthermore, since the air outlet is located on the heating side, the airflow also facilitates the dissipation of heat generated by the second heating device. Therefore, this invention solves the problem of existing multi-functional heaters where the cooking components continuously heat up, leading to accumulated heat inside the appliance that is difficult to dissipate, posing a safety hazard. It also facilitates the dissipation of heat from the heating components used for heating. Attached Figure Description

[0041] A multi-functional heater is a heater that includes multiple functions, generally including a heating component for heating and a heating component for cooking. In existing technology, the multi-functional heater arranges the electric cooking function component in the upper part of the appliance and the heating function component in the lower part of the appliance, combining the whole into the form of a table or coffee table.

[0042] However, in the existing structure, the upper and middle parts of the appliance are usually enclosed. The heating components used for cooking continuously generate heat, causing heat to accumulate in the upper and middle parts of the appliance and not dissipate. This internal heat buildup poses a safety hazard.

[0043] This utility model proposes a multifunctional heater 100.

[0044] Please see Figures 1 to 3 In one embodiment of this utility model, the multifunctional heater 100 includes a main body 1, a first heating device 2, and a second heating device 3. The first heating device 2 is disposed within the main body 1 and is positioned corresponding to the heating platform 11, for heating the heating appliance placed on the heating platform 11. The second heating device 3 is disposed within the main body 1 and is positioned corresponding to the heating side 12, for radiating heat to the surrounding area of ​​the heating side 12. An air duct is formed within the main body 1, and the air duct has an air inlet 141 and an air outlet 151 formed on the surface of the main body 1. The air outlet 151 is formed on the heating side 12. The air duct is connected to the space where the first heating device 2 is located within the main body 1. A fan 4 is disposed within the air duct, and the fan 4 is used to drive airflow to enter from the air inlet 141 of the air duct and to blow out from the air outlet 151.

[0045] In this invention, to prevent heat generated by the first heating device 2 from accumulating inside the main body 1, an air inlet 141 and an air outlet 151 are provided on the surface of the main body 1, and an air duct is formed inside the main body 1, connecting to the space where the first heating device 2 is located. Thus, a fan 4 installed within the air duct drives airflow into the air inlet 141, passing through the space where the first heating device 2 is located, thereby carrying away the heat accumulated inside the main body 1 generated by the first heating device 2, and blowing it out from the air outlet 151. Furthermore, since the air outlet 151 is located on the heating side 12, the airflow blowing out from the air outlet 151 also facilitates the dissipation of heat generated by the second heating device 3. Therefore, this invention solves the problem of existing multi-functional heaters 100 where the cooking components continuously heat up, causing accumulated heat inside the appliance to be difficult to dissipate, posing a safety hazard. It also facilitates the dissipation of heat from the heating components used for heating.

[0046] It should be noted that in the embodiments of this utility model, the first heating device 2, the second heating device 3 and the fan 4 can be turned on individually or simultaneously, depending on actual needs. This utility model does not impose any restrictions on this.

[0047] In an embodiment of this utility model, a mounting cavity 13 for mounting the first heating device 2 is formed within the main body 1, and the mounting cavity 13 constitutes at least one section of the air duct. Since the mounting cavity 13 constitutes at least one end of the air duct, and the first heating device 2 is mounted within the mounting cavity 13, it ensures that the airflow from the air inlet 141 will inevitably flow over the surface of the first heating device 2, thereby directly cooling the first heating device 2 and improving its heat dissipation effect.

[0048] It should be noted that this utility model does not limit the specific form of the first heating device 2. For example, in one embodiment of this utility model, the first heating device 2 includes an electric heating plate, and the electric heating plate and the heating platform 11 form an electric ceramic stove assembly to heat the appliance to be heated. In another embodiment of this utility model, the first heating device 2 includes a coil, and the coil and the heating platform 11 form an induction cooker assembly to heat the appliance to be heated.

[0049] To facilitate the intake of airflow from the air inlet 141 by the fan 4, the fan 4 should be positioned close to the air inlet 141. Specifically, in this embodiment of the invention, the air duct further includes an air inlet duct 14, which extends vertically. The air inlet 141 is located at the lower end of the main body 1, and the upper end of the air inlet duct 14 communicates with the mounting cavity 13. The fan 4 is located within the air inlet duct 14. Because the fan 4 is positioned within the air inlet duct 14, close to the air inlet 141, it facilitates the fan 4 in driving external air into the main body 1 and directly blowing it towards the first heating device 2 along the vertically extending air inlet duct 14. This ensures that the first high-temperature object the airflow contacts after entering the main body 1 is the first heating device 2, resulting in the most efficient cooling effect on the first heating device 2.

[0050] After the airflow passes through the first heating device 2, it flows downward and exits from the air outlet 151 of the heating side 12. To facilitate the airflow out of the main body 1 and to facilitate the dissipation of heat generated by the second heating device 3 from the main body 1, in this embodiment of the invention, a side cavity 15 is formed on the side of the main body 1, and an opening is provided on the outer wall of the side cavity 15; the second heating device 3 is installed in the side cavity 15, and the side cavity 15 communicates with the mounting cavity 13; the air duct also includes the side cavity 15, and the air outlet 151 includes the opening. That is, after the airflow passes through the first heating device 2, it flows through the side cavity 15 and then through the second heating device 3, and exits the main body 1 from the opening provided on the outer wall of the side cavity 15.

[0051] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment of the invention, the side cavity 15 is arranged in a ring along the circumference of the main body 1; the second heating device 3 is also arranged in a ring. By arranging the side cavity 15 and the second heating device 3 in a ring structure, on the one hand, the heating range of the second heating device 3 to the outer periphery is increased, and on the other hand, the middle part of the ring-arranged second heating device 3 forms an air duct, which facilitates the flow of air.

[0052] During the heat generation process of the second heating device 3, a portion of the heat is discharged to the outside of the main body 1 through the opening, while another portion is radiated into the interior of the main body 1. In order to discharge the heat generated by the second heating device 3 as much as possible to the outside, in this embodiment of the present invention, the second heating device 3 includes a heating element 31; a reflective portion 32 is formed in the side cavity 15, and the reflective portion 32 is located on the side of the heating element 31 opposite to the opening. That is to say, by providing a reflective portion 32 in the side cavity 15, and the reflective portion 32 being located on the side of the heating element 31 opposite to the opening, the heat radiated into the interior of the main body 1 by the heating element 31 is reflected to the outside of the main body 1 as much as possible, thereby ensuring that more of the heat generated by the second heating device 3 is discharged out through the opening, and also preventing safety hazards caused by excessive heat accumulation inside the main body 1.

[0053] To ensure that the heat reflected by the reflective part 32 is discharged outward through the opening, in this embodiment of the invention, the reflective part 32 is gradually concave from both the top and bottom ends towards the middle. That is, because the reflective part 32 is gradually concave from both the top and bottom ends towards the middle, the direction of the reflected heat is concentrated, and the gradually concave angle also makes the distributed heat more uniform. Furthermore, since the heating element 31 is located at the corresponding opening, it ensures that the heat reflected by the reflective part 32 is discharged outward through the opening. In another embodiment of the invention, the reflective part 32 is arranged in a ring shape. This arrangement is to cooperate with the ring-shaped side cavity 15 and the second heating device 3, improving the heating range and efficiency. It should be noted that the above embodiments can be used individually or simultaneously, and the invention does not impose any restrictions on this.

[0054] It should be noted that this utility model does not limit the specific number of the heating element 31 and the reflective part 32. Please refer to [link / reference]. Figure 4 and Figure 5 Specifically, in this embodiment of the invention, the number of heating elements 31 is two, and the corresponding number of reflective parts 32 is also two. Thus, by using a smaller number of heating elements 31, the cost is reduced while ensuring the heating angle. Please refer to... Figure 6 and Figure 7 In another embodiment of this utility model, the number of heating elements 31 is one.

[0055] Please see Figure 2In this embodiment of the present invention, a partition 16 is formed inside the main body 1, spaced between the air inlet duct 14 and the mounting cavity 13, and the air outlet 142 of the air inlet duct 14 is formed on the partition 16; the first heating device 2 is elastically mounted on the upper side of the partition 16 via an elastic member 161. That is, the first heating device 2 is elastically mounted on the upper side of the partition 16 via the elastic member 161, which, on the one hand, brings it close to the heating platform 11, allowing the first heating device 2 to better heat the heating appliance on the heating platform 11; on the other hand, since the fan 4 will vibrate the main body 1 during operation, the elastic member 161 provides a shock-absorbing effect. It should be noted that the present invention does not limit the specific location of the first heating device 2. For example, in this embodiment of the present invention, the lower end of the first heating device 2 is elastically mounted on the upper side of the partition 16 via the elastic member 161, and the upper end abuts against the heating platform 11. By using the elastic element 161, the first heating device 2 is kept in close contact with the heating platform 11, even under the condition of possible vibration from the fan 4, thus maximizing the heat conduction efficiency of the first heating device 2. In another embodiment of this utility model, the first heating device 2 is attached to the heating platform 11 by adhesive or electromagnet. This arrangement ensures that there is no direct contact between the first heating device 2 and the partition 16, thereby enhancing the heat dissipation effect of the airflow on the first heating device 2. However, this connection strength may be insufficient, and an appropriate connection method can be selected according to the actual situation. This utility model does not impose any restrictions on this.

[0056] It should be noted that this utility model does not limit the connection method between the heating element 31 and the reflector 32. In the embodiment of this utility model, a plurality of support plates 17 extending in the vertical direction are formed in the side cavity 15. The upper end of the support plate 17 is fixedly connected to the partition plate 16, and the lower end is fixedly connected to the main body 1. The support plate 17 is used to fix the heating element 31 and the reflector 32. By setting the support plate 17, the heating element 31 and the reflector 32 are fixed, and the overall structural strength of the multifunctional heater 100 is strengthened.

[0057] In an embodiment of this utility model, the fan 4 is fixedly connected to the lower side of the partition 16. By placing the fan 4 on the lower side of the partition 16, the airflow blown by the fan 4 can enter the mounting cavity 13 after exiting the fan 4, resulting in a larger airflow velocity towards the first heating device 2, thereby improving the heat dissipation efficiency of the first heating device 2. It should be noted that this utility model does not impose specific limitations on the placement of the fan 4, as long as the efficiency of the fan 4 in drawing external air meets the requirements. Specifically, in another embodiment of this utility model, the fan 4 is fixedly connected to the lower end of the main body 1 and is positioned corresponding to the air inlet 141.

[0058] During use, the multifunctional heater 100 needs to be kept in a relatively fixed position. Therefore, in this embodiment of the invention, the multifunctional heater 100 further includes a support assembly 5. The support assembly 5 includes a support base 51 and multiple support members 52. The upper end of the support base 51 is connected to the lower end of the main body 1, and the multiple support members 52 are disposed at the lower end of the support base 51. By setting the support assembly 5, one end of the multiple support members 52 is disposed at the lower end of the support base 51, and the other end directly abuts the ground, thus ensuring that the multifunctional heater 100 is kept in a relatively fixed position during use. It should be noted that this invention does not limit the specific form of the support assembly 5. For example, in another embodiment of this invention, the support base 51 is not provided, and the support members 52 are directly connected to the lower end of the main body 1.

[0059] To ensure greater stability of the multifunctional heater 100 during use, in this embodiment of the invention, the support member 52 includes a support rod 521 and a support plate 522. The upper end of the support rod 521 is fixedly connected to the lower end of the support base 51, and the support plate 522 is disposed at the lower end of the support rod 521. The support plate 522 increases the support area, making the support of the multifunctional heater 100 more stable. It should be noted that this invention does not limit the specific number of support members 52. In this embodiment, there are four support members 52, evenly distributed along the circumference of the main body 1. In other embodiments of this invention, the number of support members 52 may also be three, five, or more; this invention does not impose any limitation on this.

[0060] Please see Figure 1 and Figure 2When the multifunctional heater 100 uses the first heating device 2 to heat the heating appliance on the heating platform 11, the space at the upper end of the main body 1 may not be sufficient to place other appliances. Therefore, in this embodiment of the present invention, the main body 1 further includes a tabletop 18, which is located on the outer periphery of the heating platform 11 and extends beyond the side portion of the main body 1. The support assembly 5 also includes multiple support arms 53, which are circumferentially located on the outer side of the side portion of the main body 1. The upper end of each support arm 53 is connected to the tabletop 18, and the lower end is connected to the support base 51. In other words, by extending the tabletop 18 on the outer periphery of the heating platform 11, more appliances can be placed, expanding the placement space at the upper end of the main body 1. In addition, the connection of the support arms 53 also ensures the strength of the overall structure. It should be noted that the present invention does not limit the connection method of the support arms 53 and the support base 51. In another embodiment of the present invention, the support arms 53 and the support base 51 are integrally formed. This enhances the supporting effect of the support arm 53 on the tabletop 18.

[0061] During use, the heating platform 11 needs to conduct heat to the appliance placed on it, resulting in a high heat level. Other appliances placed on the tabletop 18 do not require heating. Therefore, to prevent the tabletop 18 from being affected by the high heat of the heating platform 11, in this embodiment of the invention, a heat insulation section 19 is provided between the tabletop 18 and the heating platform 11. This serves to separate the heating platform 11 and the tabletop 18. It should be noted that this invention does not limit the specific materials of the heating platform 11, the heat insulation section 19, and the tabletop 18, as long as the heat conduction function of the heating platform 11 and the heat insulation function of the heat insulation section 19 are not affected. In this embodiment, the heating platform 11 is made of glass, the heat insulation section 19 is made of plastic, and the tabletop 18 is made of wood. Furthermore, this invention does not limit the specific number of heat insulation sections 19; for example, a single layer of heat insulation sections 19 or multiple layers of heat insulation sections 19 can be used.

[0062] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
