Description

Technical Field

[0001] This utility model relates to a multifunctional heating device. Background Technology

[0002] Heaters are common heating devices in winter, and can be divided into several types based on their heating principle and usage scenarios. Common classifications include: 1. Oil-filled radiators: Use heat-conducting oil as the medium, providing even and long-lasting heat dissipation, suitable for bedrooms or living rooms. Disadvantages include slow heating and high power consumption. 2. Fan heaters: Utilize ceramic heating elements to heat the air, providing rapid heating, suitable for small spaces. Some models support humidification and intelligent temperature control. 3. Mini-sun heaters (infrared reflective type): Heat through far-infrared radiation, providing strong directionality, suitable for rapid localized heating. However, the surface temperature is extremely high (up to 600℃), so they must be kept away from flammable materials.

[0003] Kitchen heating appliances refer to electrical products specifically designed for food preparation or processing in the kitchen, such as air fryers and ovens.

[0004] Although both heaters and kitchen heating appliances have heating functions, there are very few appliances on the market that combine the two. For example, heaters are limited in function, only used to raise the ambient temperature, resulting in heat waste.

[0005] A prior art example, referring to patent document CN217592549U, discloses a cooking heating device that can be used for heating, including a heating base, an infrared radiation heat groove disposed on the heating base, an infrared heating tube disposed in the infrared radiation heat groove, and a guide cover covering the infrared radiation heat groove. The guide cover includes a reflective body and an emission part disposed on one side of the reflective body. The cooking heating device of this utility model can be used as a heating device for a health pot and also as a heater. It has high electrothermal conversion efficiency, energy saving and consumption reduction, high heating efficiency, rapid heating, and can shorten the cooking time required for food.

[0006] The heating devices described above have the functions of heating and cooking, but they also have obvious drawbacks. The heating components can only radiate heat outwards through radiation, which has low heating efficiency for the space and is also not very effective at heating containers. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a multifunctional heating device with good heating effect on space and cookware.

[0008] The technical solution of this utility model to solve its technical problem is: a multifunctional heating device, comprising:

[0009] The casing has several heat dissipation holes on it;

[0010] A heating element for providing heat, said heating element being disposed within said housing;

[0011] The air circulation component, housed within the housing, includes a motor and fan blades. The air circulation component transfers the heat from the heating component to the outside of the housing through heat dissipation holes.

[0012] The pot body assembly is removably and securely fitted onto the shell.

[0013] The motor can be selectively activated. When the motor is activated, the fan blades apply some heat to create a hot airflow, which dissipates outward through the heat dissipation holes. Simultaneously, another portion of the heat is radiated outward through the heat dissipation holes. When the motor is not activated, heat is radiated outward through the heat dissipation holes. When the pot assembly is detached from the housing, the heating device functions as a heating device; when the pot assembly is assembled onto the housing, the heating device functions as a cooking device.

[0014] When the pot assembly is separate from the outer shell, the outer shell can function as a heater on its own. When the pot assembly is attached to the outer shell, the outer shell acts as the heat source for cooking. When the motor is activated, the fan blades improve heat diffusion, resulting in better space heating. Furthermore, when used with the pot assembly, if heat can enter the container, the heating effect on the container is enhanced. On the other hand, the pot assembly is nested outside the outer shell, resulting in a larger contact area between the pot assembly and the outer shell, which further improves the heating effect on the container.

[0015] In a preferred embodiment of the present invention, the housing includes a base portion and a heat dissipation portion, the heat dissipation portion is formed on the upper end of the base portion, the heating component and the fan blade are disposed inside the heat dissipation portion, and the heat dissipation holes are distributed on the peripheral wall of the heat dissipation portion.

[0016] The pot body assembly is a first pot body, and the bottom of the first pot body has a receiving cavity that fits with the heat dissipation part.

[0017] By employing the technical solution of the above preferred embodiment, the heat dissipation part and the accommodating cavity are spatially coordinated, resulting in a larger heat conduction area between the pot body assembly and the shell, thereby improving the heating rate and obtaining a better cooking experience. The first pot body, in use, can function similarly to a hot pot, soup pot, or wok.

[0018] In another preferred embodiment of the present invention, the housing includes a base portion and a heat dissipation portion, the heat dissipation portion is formed on the upper end of the base portion, the heating component and the fan blade are disposed inside the heat dissipation portion, and the heat dissipation holes are distributed on the peripheral wall of the heat dissipation portion.

[0019] The pot body assembly is a second pot body, with a receiving cavity formed at the bottom that fits with the heat dissipation part. An air inlet is provided on the receiving cavity of the second pot body to receive the hot airflow overflowing from the heat dissipation part.

[0020] The second pot body with the above-described structure has a heat dissipation section and a housing cavity that work together spatially, resulting in a larger heat conduction area between the pot body assembly and the outer shell. This improves the heating rate and provides a better cooking experience. Additionally, the second pot body is equipped with air inlets, allowing the air circulation assembly to direct the hot airflow from the heating element into the second pot body. During use, it provides cooking functions similar to those offered by an air fryer or oven.

[0021] Furthermore, the top of the heat dissipation section is provided with a return air hole, and the accommodating cavity of the second pot body is provided with an air outlet corresponding to the return air hole, so as to make the return air smoother and accelerate the flow efficiency of hot air.

[0022] Using the above structure, the heating component heats the surrounding air, and the air circulation component draws the hot air into the second pot through the heat dissipation holes and air inlet holes to heat the food. Finally, the hot air returns to the fan blades through the air outlet holes of the second pot and the return air holes of the heat dissipation unit, completing the heat circulation.

[0023] Optionally, the fan blades and heating components extend along the height direction of the heat dissipation section.

[0024] With the above structure, the higher the heat dissipation part is, the larger the area of ​​hot air that diffuses outward, which can improve the efficiency of heating and heating the pot body components.

[0025] Optionally, the motor is disposed inside the base portion, and the output shaft of the motor extends into the heat dissipation portion and connects to the fan blades.

[0026] By adopting the above structure, the motor is kept away from high-temperature areas, thus ensuring the operating temperature of the motor.

[0027] Optionally, the base portion is flared, wider at the bottom and narrower at the top.

[0028] This structure allows for a larger contact area between the housing and the supporting surface, resulting in a more stable position. Furthermore, the base will have a larger internal space to better accommodate components such as the motor.

[0029] The above structure allows for a larger contact area between the shell and the supporting surface, resulting in a more stable position.

[0030] In this invention, the housing is provided with a control element, which is electrically connected to the heating component and the air circulation component to control the starting and stopping of the heating component, motor and other components.

[0031] The beneficial effects of this utility model are as follows:

[0032] First, while ensuring heating, the heat emitted can be used for cooking when combined with the pot assembly, achieving multiple functions in one machine. When camping outdoors, this device can meet the needs of heating and cooking food, eliminating the need to carry multiple devices.

[0033] Second, it has a wind circulation component, which can act on the heat of the heating component to form a hot airflow, greatly improving heat dissipation efficiency.

[0034] Third, the motor can be selectively activated, allowing the heat dissipation method to be switched between thermal radiation and hot air convection as needed.

[0035] Fourth, it provides diverse cooking functions. When the pot body component is the first pot body with a closed accommodating cavity, it can perform cooking functions similar to those provided by a hot pot, soup pot, or wok. When the pot body component is the second pot body with an open accommodating cavity, it can perform cooking functions similar to those provided by an air fryer or oven.

[0036] Fifth, the heat dissipation unit and the housing cavity work together spatially, providing a larger heat conduction area, thereby increasing the heating rate and resulting in a better cooking experience. On the other hand, when the heat dissipation unit is located within the housing cavity, the contact area between the heat dissipation unit and the external space of the shell is greatly reduced, thereby reducing heat loss and improving heat utilization.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0047] Reference Figures 1-6 A multifunctional heating device includes: a housing 1 with several heat dissipation holes 122; a heating element 3 for providing heat, the heating element 3 being disposed within the housing 1; a wind circulation component 4 disposed within the housing 1, including a motor 41 and fan blades 42; and a pot body component 5 removably fitted onto the housing 1. The wind circulation component 4 transports the heat from the heating element 3 to the outside of the housing 1 through the heat dissipation holes 122. The motor 41 can be selectively activated; when the motor 41 is activated, the fan blades 42 agitate the airflow, and the hot airflow dissipates to the outside of the housing 1 through the heat dissipation holes 122, while another portion of the heat is also radiated to the outside of the housing 1 through the heat dissipation holes 122; when the motor 41 is not activated, heat is radiated to the outside of the housing 1 through the heat dissipation holes 122.

[0048] Reference Figure 2When the pot assembly 5 is removed from the housing 1, the heating device is used as a heating device; see reference Figure 1 When the pot body assembly 5 is assembled onto the housing 1, the heating device is used as a cooking device.

[0049] The air circulation component 4 has a motor 41 and a fan blade 42, which can act on the heat of the heating component 3 to form a hot airflow, greatly improving heat dissipation efficiency; secondly, while ensuring heating and warmth, it can be used for cooking in conjunction with the pot body component 5; thirdly, it is multi-functional, and the device can meet the needs of heating and cooking food when camping outdoors, eliminating the need to carry multiple devices.

[0050] When used as a heating device, if motor 41 is not activated, the device radiates heat outwards through thermal radiation, similar to a small electric heater. If motor 41 is activated, the device radiates heat outwards through both thermal radiation and convection, similar to a fan heater. When used as a cooking device, the pot assembly 5 is placed on the shell 1, and heat is provided to the pot assembly 5 through thermal radiation and / or convection to achieve the cooking function.

[0051] In this invention, the housing 1 is equipped with a control element, which is electrically connected to the heating assembly 3 and the air circulation assembly 4. The control element is electrically connected to mains power, an outdoor portable power source, or a new energy vehicle, or has a built-in battery module to obtain power. The control element also includes a switch to control the starting and stopping of components such as the heating assembly 3 and the motor 41.

[0052] The fan blades 42 and heating assembly 3 extend along the height of the heat dissipation section 12, so that the fan blades 42 can evenly and fully dissipate the heat generated by the heating assembly 3. In this embodiment, the fan blades 42 are cross-flow fan blades, which are vertically placed in the heat dissipation section 12, discharging air from the periphery and returning air from the axial side; the heating assembly 3 is a heating tube, which is spirally wrapped around the outside of the cross-flow fan blades. The higher the heat dissipation section 12, the larger the area of ​​hot air that diffuses outward, which can improve the efficiency of heating and heating the pot assembly 5.

[0053] Reference Figure 3 , Figure 5The housing 1 includes a base portion 11 and a heat dissipation portion 12. The heat dissipation portion 12 is formed on the upper end of the base portion 11. The heating component 3 and the fan blade 42 are disposed within the heat dissipation portion 12, and the heat dissipation holes 122 are distributed on the peripheral wall of the heat dissipation portion 12. The pot body assembly 5 is a first pot body 51, and the bottom of the first pot body 51 has a receiving cavity 5a that fits and mates with the heat dissipation portion 12. The pot body assembly 5 with the above structure can perform cooking functions similar to those of a hot pot, soup pot, or wok during use.

[0054] The accommodating cavity 5a is formed by recessing from the bottom of the first pot body 51 into the interior of the first pot body 51. The first pot body 51 then fits the accommodating cavity 5a over the heat dissipation part 12 to complete the installation. The heat dissipation part 12 and the accommodating cavity 5a cooperate spatially, resulting in a larger heat conduction area between the pot body assembly 5 and the shell 1, thereby increasing the heating rate and providing a better cooking experience. On the other hand, the cooperation between the heat dissipation part 12 and the accommodating cavity 5a allows the shell 1 to directly provide structural support for the pot body assembly 5. In addition, the pot body assembly 5 surrounds the heat dissipation part 12, preventing it from being exposed, thus providing isolation and protection during the cooking stage and improving safety during use.

[0055] Optionally, the base portion 11 is flared, wider at the bottom and narrower at the top, so that the housing 1 can have a larger contact area with the supporting surface, resulting in a more stable position. On the other hand, the base portion 11 will have a larger internal space to better accommodate components such as the motor 41.

[0056] Preferably, the motor 41 is disposed inside the base portion 11, and the output shaft of the motor 41 extends into the heat dissipation portion 12 and connects to the fan blade 42. This keeps the motor away from high-temperature areas to ensure the motor's operating temperature. Example

[0057] A multifunctional heating device, which differs from Embodiment 1 in that the pot body component 5 is different.

[0058] In this embodiment, the pot assembly 5 is a second pot body 52, with a receiving cavity 5a formed at the bottom that fits with the heat dissipation part 12. An air inlet 521 is provided on the receiving cavity 5a of the second pot body 52 to receive hot airflow overflowing from the heat dissipation part 12. The pot assembly 5 with the above structure can perform cooking functions similar to those provided by an air fryer or oven during use.

[0059] Furthermore, the top of the heat dissipation part 12 is provided with a return air hole 121, and the accommodating cavity 5a of the second pot body 52 is provided with an air outlet hole 522 corresponding to the return air hole 121, so as to make the return air smoother and accelerate the flow efficiency of hot air.

[0060] Reference Figure 4Specifically, the hot airflow first exits from the heat dissipation holes 122 on the outer shell 1 and then enters the second pot body 52 through the air inlet 521. In the second pot body 52, the hot airflow encounters the side wall and flows upwards. It then exits from the air outlet 522 in the second pot body 52 and returns to the outer shell 1 through the return air hole 121, forming a circulating flow effect. After reheating, the next cycle of circulation begins. With this airflow effect, firstly, it can balance the pressure inside and outside the second pot body 52, preventing safety issues caused by excessive pressure inside the second pot body 52; secondly, the circulating hot airflow can improve cooking efficiency.

[0061] It is worth mentioning that the heat dissipation part 12 and the accommodating cavity 5a are spatially coordinated, resulting in a larger heat conduction area between the pot body assembly 5 and the shell 1, thereby increasing the heating rate and providing a better cooking experience. On the other hand, when the heat dissipation part 12 is located in the accommodating cavity 5a, the contact area between the heat dissipation part 12 and the external space of the shell 1 can be greatly reduced, thereby reducing heat loss and improving heat utilization.

[0062] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
