Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a fireplace that integrates heat dissipation and heating functions. Background Technology

[0002] Currently, fire-warmers are widely used in household appliances because they can not only provide warmth but also allow for brewing tea and heating food on the fire platform. Existing fire-warmers typically include a fire platform with an electric ceramic stove embedded in it for heating purposes. In addition, exhaust vents are installed around the perimeter of the stove heater to dissipate heat from the inner cavity of the stove heater. However, in the existing technology, the fan is placed at the bottom of the stove heater, and the output airflow directly acts on the back of the electric ceramic stove. The airflow passing through the electric ceramic stove may still flow back into the inner cavity, affecting the normal operating temperature of the internal electrical control components. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fireplace that integrates heat dissipation and heating functions.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A fireplace with integrated heat dissipation and heating functions includes a shell assembly, a fireplace platform panel disposed above the shell assembly, and an air outlet seat disposed between the fireplace platform panel and the shell assembly. A fan is provided between the air outlet seat and the shell assembly. An electrical cavity for accommodating electrical components is defined inside the shell assembly. An air outlet is provided around the air outlet seat. The air outlet seat is located on the air supply side of the fan, and the electrical cavity is located on the air inlet side of the fan.

[0005] Furthermore, a heating plate is provided on the top of the air outlet seat, the heating plate constitutes the heating area on the furnace platform panel, the air outlet side of the fan is set directly opposite the heating plate, and the air outlet is set on the circumferential outer side of the heating plate.

[0006] Furthermore, the housing assembly includes a base, the bottom of which has an air inlet area communicating with the electrical cavity. The air inlet area includes a first part facing the fan and a second part adjacent to the first part, and the projection of the electrical component is at least partially located within the second part.

[0007] Furthermore, the air outlet extends toward the bottom of the stove panel and the top of the housing assembly in the height direction.

[0008] Furthermore, the heating plate extends at least partially toward the inside of the air outlet seat, and the height of the heating plate inside the air outlet seat is lower than the highest position of the air outlet.

[0009] Furthermore, the housing assembly includes an upper shell and a base that are joined together. The upper shell has a mounting seat that communicates with the air outlet seat and the electrical cavity. The fan is placed in the mounting seat, and the periphery of the mounting seat forms a partition that separates the electrical cavity from the air outlet seat. The partition has wiring through holes.

[0010] Furthermore, a heating tube is provided on the housing assembly, and a reflector is provided between the heating tube and the electrical cavity.

[0011] Furthermore, a mesh cover is provided outside the heating tube, and the mesh cover forms the surface contour of the housing assembly.

[0012] Furthermore, the furnace panel includes a placement area disposed around the heating area, the placement area extending radially around the air outlet seat and covering the air outlet.

[0013] Furthermore, the bottom of the housing assembly is provided with a support leg, which supports the housing assembly and suspends the air intake area.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention features a furnace platform panel, an air outlet seat, and a housing assembly arranged in a vertically partitioned manner. A fan is installed between the air outlet seat and the housing assembly, and the electrical control components are housed within the electrical cavity of the housing assembly. The airflow from the fan removes heat from inside the housing assembly, ensuring that the airflow from the fan passes through the bottom of the heating plate before exiting to the air outlet. The airflow can then be smoothly discharged from the air outlets around the air outlet seat, preventing backflow and effectively dissipating heat from the electrical cavity. This ensures the normal operation of the internal electrical control components and effectively solves the problem in the prior art where backflow affects the normal operating temperature of the internal electrical control components. In addition, a heating plate is installed at the junction of the top of the air outlet and the stove panel. While the stove panel is performing the heating function, the air outlet side of the fan is positioned directly opposite the heating plate, and the air outlet is located on the outer periphery of the heating plate. This allows the output airflow to carry away the heat inside the electrical control cavity while simultaneously dissipating heat from the bottom of the heating plate. In other words, warm air is output through the air outlet, thus integrating heat dissipation and heating functions at the air outlet. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0018] like Figures 1 to 7 As shown, a fireplace integrating heat dissipation and heating functions includes: The system comprises a housing assembly 1, a stovetop panel 2 positioned above the housing assembly 1, and an air outlet seat 3 positioned between the stovetop panel 2 and the housing assembly 1. A fan 4 is located between the air outlet seat 3 and the housing assembly 1. The housing assembly 1 internally defines an electrical cavity 1.3 that accommodates electrical components 10. The stovetop panel 2 serves as the user's operating surface, with a heating area 2.1 in the center for placement of heating components. The air outlet seat 3 has air outlets 3.1 on its periphery. The air outlet seat 3 is located on the air supply side of the fan 4, and the electrical cavity 1.3 is located on the air intake side of the fan 4. The air outlet seat 3 connects the housing assembly 1 and the stovetop panel 2 to form an overall frame, and conducts heat between the heating area 2.1 and the air outlet side airflow in the air outlet seat 3. The air intake side airflow drives the heat output from the housing assembly 1, thus ultimately forming a warm airflow output from the air outlet 3.1, thereby constructing a combined heat dissipation and heating air duct system, making the airflow path clear and unidirectional.

[0019] As a further implementation of the airflow path within the air outlet seat 3, a heating plate 5 is provided on the top of the air outlet seat 3. The heating plate 5 constitutes the heating area 2.1 on the stove panel 2. The air outlet side of the fan 4 is positioned directly opposite the heating plate 5, and the air outlet 3.1 is located on the outer periphery of the heating plate 5. The airflow blown out by the fan 4 directly acts on the heating plate 5. After sufficient heat exchange, the hot air is forced to be horizontally discharged from the air outlet 3.1 on the periphery of the heating plate 5, forming a uniform annular warm flow, providing comfortable surround heating, avoiding heat accumulation at the top of the inner cavity, and improving heating efficiency and user experience.

[0020] Preferably, the air outlet seat 3 is open at the top so that the bottom part of the heating plate 5 can be placed inside the air outlet seat 3, so that the airflow output from the fan 4 can be fully applied to the heating plate 5. The part of the heating plate 5 that is placed inside constitutes the heat dissipation and heat conduction part, heating the airflow output from the air outlet 3.1.

[0021] Preferably, the heating area 2.1 of the furnace panel 2 is provided through, and the heating plate 5 is placed therein to form a heating surface.

[0022] Specifically, the housing assembly 1 is also provided with an air inlet area, which is preferably located below the air outlet 3.1.

[0023] During operation, cool ambient air enters the electrical cavity 1.3 through the air intake area at the bottom of the base 1.2. As the airflow passes through the electrical cavity 1.3 and the electrical components 10 inside, it carries away the heat generated during operation, achieving effective active heat dissipation for the electrical components. Subsequently, the airflow preheated by the electrical cavity 1.3 is drawn in by the fan 4. The heating plate 5 heats the furnace platform 2 during operation, providing heat to the heating area 2.1 and the space above the furnace platform 2, and blows it towards the heating plate 5 located at the top of the air outlet seat 3. The heating plate 5 is directly facing the heating area 2.1 of the furnace platform 2. The airflow carries away the heat from the heating plate 5 itself, thereby achieving heat dissipation for the heating plate 5 and the electrical cavity 1.3. At the same time, the airflow becomes hot air after the above heat exchange and is finally discharged from the air outlet 3.1 provided around the air outlet seat 3.

[0024] In this embodiment, the problems of hot air backflow and turbulence inside the equipment are effectively avoided, ensuring a low-temperature operating environment for the components within the electrical cavity 1.3, and significantly improving the product's reliability and service life. Simultaneously, the airflow used for heat dissipation is cleverly converted into heating airflow, achieving highly efficient functional integration.

[0025] It is worth mentioning that by arranging the air intake area at the bottom of the shell assembly 1 and placing the electrical component 10 at the upper part of the electrical cavity 1.3, the ambient cold air can be fully utilized in the electrical cavity 1.3, optimizing the heat dissipation effect on the electrical component 10. At the same time, combined with the air outlet 3.1 at the top of the shell assembly 1, an air heat circulation path is formed below the stove panel 2, improving the heating effect.

[0026] As a further embodiment of the housing assembly 1, the housing assembly 1 includes an upper shell 1.1 and a base 1.2 that are joined together. The upper shell 1.1 and the base 1.2 are connected to each other by fastening or bolting. To ensure the reliability of the air duct isolation, a mounting seat 1.4 is provided inside the upper shell 1.1. The mounting seat 1.4 is preferably located in the middle of the upper shell 1.1, and the fan 4 is fixedly placed therein. The mounting seat 1.4 is connected to the air outlet seat 3 and the electrical cavity 1.3. The periphery of the mounting seat 1.4 forms a partition 1.5 that separates the electrical cavity 1.3 and the air outlet seat 3. The partition 1.5 isolates the two functional areas of the air outlet seat 3, ensuring unidirectional airflow and sealing from the electrical cavity 1.3 to the air outlet seat 3, preventing hot air backflow, and also providing a stable mounting foundation for the fan 4.

[0027] from Figure 8 As can be seen, the partition 1.5 has only one wiring via 6 to facilitate wiring. The number of wiring via 6 is preferably one, which realizes a compact, safe and reliable integrated design. The wiring via 6 is mainly used to connect the heating plate 5 to the electrical components 10 in the electrical cavity 1.3.

[0028] from Figure 5As can be seen, the housing assembly 1 includes a base 1.2. The bottom of the base 1.2 is provided with an air inlet area that communicates with the electrical cavity 1.3. The air inlet area includes a first part 1.21 facing the fan 4 and a second part 1.22 adjacent to the first part 1.21. The projection of the electrical component 10 is at least partially located within the second part 1.22. In this embodiment, the first part 1.21 and the second part 1.22 are used to ensure airflow. When the electrical component 10 is exposed from the second part 1.22, the cold airflow from the external environment can directly act on the electrical component 10 under the action of the fan 4, achieving a high-efficiency heat dissipation effect.

[0029] Preferably, the first part 1.21 and the second part 1.22 are evenly distributed on the bottom of the base 1.2, the first part 1.21 is located in the middle of the bottom of the base 1.2, and the second part 1.22 is located on the outer periphery of the first part 1.21.

[0030] The housing assembly 1 has a support leg 8 at its bottom, which supports the housing assembly 1 and suspends the air intake area. The entire device is supported by the support leg 8 at the bottom, which suspends the air intake area and ensures that the cooling airflow can enter unimpeded.

[0031] Further reference Figure 6 As shown, to further ensure the airflow output effect after heat exchange, the air outlet 3.1 extends towards the bottom of the stove panel 2 and the top of the shell assembly 1 in the height direction. That is, the air outlet 3.1 extends in the vertical direction, which expands the coverage area of ​​the warm air. The purpose of the upward extension is to allow the airflow through the heating plate 5 to be output more smoothly and to avoid the accumulation of airflow in the air outlet seat 3. The downward extension sends the heat to the lower space to warm the lower part of the user's body, which greatly improves the comfort of heating.

[0032] In this embodiment, the air outlet 3.1 is a vertically extending strip-shaped opening.

[0033] Specifically, the heating plate 5 extends at least partially toward the inside of the air outlet seat 3 to provide a larger heat dissipation area and improve the heat exchange efficiency of the airflow. The height of the heating plate 5 inside the air outlet seat 3 is lower than the highest position of the air outlet 3.1 to avoid airflow obstruction.

[0034] As a further improvement to the stove panel 2, the stove panel 2 includes a placement area 2.2 disposed around the heating area 2.1. The placement area 2.2 extends radially around the top of the air outlet seat 3 and covers the air outlet 3.1. The stove panel 2 covering the air outlet 3.1 guides the airflow output from the air outlet 3.1, which is conducive to guiding the airflow to circumferentially. In addition, to a certain extent, the residual heat discharged from the air outlet 3.1 can continuously keep items such as teapots placed in the area warm.

[0035] Further reference Figure 4 As one embodiment of the furnace platform panel 2 and the heating plate 5, the furnace platform panel 2 includes a connecting plate 2.3 arranged in a ring around the heating plate 5. The heating plate 5 is also provided with a fixing frame 5.1 around its periphery. The heating plate 5 is supported on the fixing frame 5.1. The inner side of the connecting plate 2.3 is fixed to the fixing frame 5.1 by bolts. The outer side of the connecting plate 2.3 is fixed to the placement area 2.2 of the furnace platform panel 2 by bolts. The connecting plate 2.3 is mounted on the air outlet seat 3 and fixed to the end face of the air outlet seat 3 by bolts. The lower end of the air outlet seat 3 is fixed to the top of the housing assembly 1 by bolts.

[0036] The top of the housing assembly 1 is also provided with a positioning groove 1.7 for inserting the lower end of the air outlet seat 3.

[0037] like Figure 3 and Figure 6 As shown, in some other embodiments, to further improve the heating effect of the fireplace, a heating pipe 7 is provided on the shell assembly 1, and a reflector 7.1 is provided between the heating pipe 7 and the electrical cavity 1.3. This allows for effective heating around the shell assembly 1, and the warm air output through the air outlet 3.1 and the heat released by the heating pipe 7 around the shell assembly 1 provide sufficient heating for the user's abdomen and legs.

[0038] Specifically, the heating tube 7 is preferably built into the housing assembly 1. For example, a reflector 7.1 is provided around the periphery of the housing assembly 1, which provides the installation position for the heating tube 7. The reflector 7.1 tends to be concave relative to the housing assembly 1, and a mesh cover 7.2 is provided outside the heating tube 7, which forms the surface contour of the housing assembly 1.

[0039] To further optimize the heat dissipation effect inside the housing assembly, the reflector preferably has an arc-shaped expansion tendency inside the housing assembly. The lower end of the reflector is connected to the base and located on the periphery of the air intake area. The upper end of the reflector is connected to the bottom of the upper shell, and the outer diameter of the upper shell is larger than the outer diameter of the base. Thus, when the airflow enters the housing assembly through the air intake area, part of the airflow can be guided by the reflector and fully act on the electrical cavity, thereby carrying away the heat inside the electrical cavity.

[0040] Preferably, the housing assembly 1 is configured from top to bottom as an electrical cavity 1.3 and a mounting cavity 1.6. The electrical components 10 are all disposed in the upper electrical cavity 1.3. The mounting cavity 1.6 is defined by the reflector 7.1 and the heating pipe 7 on the periphery of the housing assembly 1, so as to separate the electrical components 10 from the area below the electrical cavity 1.3 corresponding to the heating pipe 7, while maintaining airflow communication between the electrical cavity 1.3 and the mounting cavity 1.6, so that the heat from the heating pipe 7 is carried out by the airflow on the air inlet side of the fan 4 and conducted to the inner cavity of the housing assembly 1 through the reflector 7.1.

[0041] from Figure 7 As can be seen, in one embodiment of the heating tube 7 assembly, a hanger 9 is provided between the heating tube 7 and the reflector 7.1. The hanger 9 includes a hole 9.1 through which the heating tube 7 passes, and a bent portion 9.2 through which the reflector 7.1 passes. There are multiple hangers 9, and the hangers 9 are preferably sheet-shaped metal parts. Multiple hangers 9 are spaced apart to ensure the heat release and suspension stability of the heating tube 7. Correspondingly, the reflector 7.1 is provided with a slot 7.3 that matches the bent portion 9.2. During the assembly process, the bent portion 9.2 passes through the slot 7.3 and is bent vertically so that the bent portion 9.2 abuts against the wall of the reflector 7.1 away from the heating tube 7, thereby fixing the heating tube 7 to the reflector 7.1.

[0042] like Figure 8 As shown, specifically, the reflector 7.1 is also provided with a through hole 7.4, which is used to introduce the wiring of the heating tube 7 into the electrical cavity 1.3. The through hole 7.4 is provided with a heat insulation kit.

[0043] This utility model integrates heat dissipation duct and heating function through a unique structural layout. Utilizing a clear unidirectional flow field, it ensures stable operation of internal electrical components at low temperatures while transforming heat dissipation airflow into comfortable heating air, achieving a balance between high efficiency and high reliability.

[0044] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
