Description

Technical Field

[0001] The utility model belongs to a heater, in particular to a heater with uniform air output. Background Art

[0002] As a heating device, heaters are widely used. The air outlets of many heaters are fixed, such as the heater disclosed in application number 201620588227.7. When heating, the heat around the heating element will be relatively high. Therefore, when heating, it is easy to cause the temperature at the position where the air outlet is facing the heating element to be higher, while the temperature of the air at the surrounding positions is relatively low. The air outlet temperature is uneven, resulting in local overheating during heating, while the temperature nearby is obviously insufficient. Utility Model Content

[0003] The purpose of the present utility model is to provide a heater with uniform air output that can solve at least one of the above problems.

[0004] According to one aspect of the utility model, a heater with uniform air output is provided, comprising an outer shell, a simulated flame cover, a heating element, a fan and an air guide wheel. The simulated flame cover, the heating element, the fan and the air guide wheel are all located inside the outer shell, the heating element is located at the upper part of the outer shell, the fan is located below the heating element, and the air guide wheel is located above the heating element. A third ventilation hole is provided on the top of the outer shell, the air guide wheel corresponds to the third ventilation hole, the outer diameter of the air guide wheel is consistent with the inner diameter of the outer shell, the first ventilation hole is provided around the entire circle of the outer shell, and the first ventilation hole is located above the fan.

[0005] The beneficial effect of the present invention is that by providing a fan and an air guide wheel, when the heating element is working, the heat generated is blown upwards by the action of the fan, and through the guiding action of the air guide wheel, the heat can be guided from the middle to the periphery, so that after the hot air passes through the air guide wheel, it can evenly fill the entire space inside the outer shell above the air guide wheel, and finally the hot air can evenly flow out through the first ventilation hole and the third ventilation hole, avoiding the heat concentration around the heating element, avoiding the phenomenon of excessively high local heating temperature, and improving the comfort during heating.

[0006] In some embodiments, a heater with uniform air flow further includes a cover plate disposed on a top end of the housing, wherein the outer diameter of the cover plate is larger than the outer diameter of the housing. Thus, by providing the cover plate and extending beyond the edge of the housing, the hot air can be blocked, allowing the upward hot air to flow in all directions under the action of the cover plate.

[0007] In some embodiments, the portion of the cover plate that extends beyond the housing is horizontally arranged or tilted downward, thereby allowing the hot air to be better diffused to the surroundings.

[0008] In some embodiments, a heater with uniform air output further includes a conical guide plate, which is located inside the housing and above the guide wheel, and the outer diameter of the top of the conical guide plate is larger than the outer diameter of the bottom. Thus, the fan can blow the hot air generated by the heating element upward and act on the conical guide plate; because the outer diameter of the top of the conical guide plate is larger than the outer diameter of the bottom, when the hot air acts on the conical guide plate, under the guidance of the conical guide plate, the hot air flows along the side walls of the conical guide plate to the surrounding areas and can be dispersed through the first ventilation holes on the surrounding areas, thereby ensuring uniform air output on all sides of the heater, facilitating continuous heating on all sides of the housing and improving comfort during use.

[0009] In some embodiments, the air guide wheel includes an outer peripheral plate and multiple guide plates. The outer peripheral plate is located outside the guide plate. Air guide ports are formed between adjacent guide plates and the outer peripheral plate. The bottom diameter of the air guide port is smaller than the top diameter of the air guide port. Thus, the air guide port guides the hot air from the center to the surrounding area, allowing the hot air to be dissipated through the first ventilation holes on the surrounding area.

[0010] In some embodiments, the outer periphery of the housing is provided with a second ventilating hole, the second ventilating hole being located between the simulated flame cover and the fan, and the simulated flame cover being located at the bottom of the housing. Thus, through the second ventilating hole, it is convenient for outside air to enter the housing, which is beneficial to the normal operation of the fan.

[0011] In some embodiments, a heater with uniform air flow further comprises a bottom cover, which is arranged at the bottom end of the housing, and the simulated flame cover is fixed on the bottom cover. Thus, by providing the bottom cover, the simulated flame cover can be installed and fixed.

[0012] In some embodiments, the bottom cover is provided with a groove, the bottom end of the shell matches the groove, and the width of the groove is consistent with the thickness of the bottom end of the shell. Thus, by providing the groove, the shell and the bottom cover can be quickly matched.

[0013] In some embodiments, a heater with uniform air flow further includes an adjustment button disposed on the outside of the housing and electrically connected to the heating element, thereby facilitating on / off control of the heating element via the adjustment button.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 、 Figure 2 and Figure 5 In one embodiment, a heater with uniform air output includes a shell 1, a simulated flame cover 2, a heating element 3, a fan 4 and an air guide wheel 7. The simulated flame cover 2, the heating element 3, the fan 4 and the air guide wheel 7 are all located in the shell 1, the heating element 3 is located at the upper part of the shell 1, the fan 4 is located below the heating element 3, and the air guide wheel 7 is located above the heating element 3. A third ventilation hole 13 is provided on the top of the shell 1, and the air guide wheel 7 corresponds to the third ventilation hole 13, that is, hot air can flow out through the third ventilation hole 13 through the action of the air guide wheel 7. The outer diameter of the air guide wheel 7 is consistent with the inner diameter of the shell 1. The shell 1 is provided with a first ventilation hole 11 throughout the entire circle, and the first ventilation hole 11 is located above the fan 4.

[0022] In this embodiment, the third ventilation holes 13 face the air guide wheel 7. Therefore, the fan 4 blows the heat generated by the heating element 3 upward to form hot air. Under the guidance of the air guide wheel 7, the hot air diffuses from the center to the surrounding area, so that the heat can be evenly distributed above the air guide wheel 7. Under the influence of the airflow of the fan 4, the heat can be dissipated from the first ventilation holes 11 and the third ventilation holes 13. As a result, the temperature of the hot air dissipated from the third ventilation holes 13 at various positions above the housing 1 is uniform, and the phenomenon of excessively high local temperatures is avoided.

[0023] like Figures 3 to 6 As shown, in another embodiment, a heater with uniform air output further includes a conical guide plate 5, which is located in the outer shell 1 and above the air guide wheel 7, and the outer diameter of the top end of the conical guide plate 5 is greater than the outer diameter of the bottom end thereof.

[0024] By inverting the conical guide plate 5, hot air can be directed from the center to the surrounding areas, allowing heat to flow evenly around the periphery, facilitating heating of the entire periphery of the housing 1. Even heat distribution can be achieved without the need for a rotating structure, simplifying the overall structure. The simulated flame hood 2 utilizes the simulated flame technology used in existing fan heaters. A light source is installed within the simulated flame hood 2, simulating the flame effect of a real flame through lighting effects. The specific principles will not be elaborated here.

[0025] To ensure that the conical guide plate 5 guides the hot air, the outer diameter of the top of the conical guide plate 5 is consistent with the inner diameter of the outer shell 1. This prevents the hot air from flowing upward between the conical guide plate 5 and the outer shell 1, thereby facilitating the even dispersal of the hot air in all directions. Furthermore, the top of the conical guide plate 5 is flush with the top of the outer shell 1, ensuring that the hot air can flow out uniformly through the first vents 11.

[0026] When in use, heat is generated by the heating element 3, and the fan 4 rotates to blow the heat upward to form upward hot air. The upward hot air acts upward on the conical guide plate 5. Through the guiding effect of the conical guide plate 5, the hot air diffuses from the middle to the surroundings and finally flows out through the first ventilation hole 11. The air is discharged evenly in all directions to achieve the heating effect.

[0027] During the actual installation process, the fan 4 and the heating element 3 can be fixed to the inner wall of the shell 1 by screws; or a mounting plate can be welded and fixed to the inner wall of the shell 1, and the fan 4 and the heating element 3 can be fixed to the mounting plate by screws, which is convenient for installation.

[0028] The heater with uniform air output according to the present invention also includes a cover plate 6, which is positioned over the top of the housing 1. The outer diameter of the cover plate 6 is larger than that of the housing 1. During assembly, the top of the housing 1 can be formed with a folded edge, and the cover plate 6 is screwed to the folded edge of the housing 1. In the first embodiment, the third ventilation hole 13 is formed in the cover plate 6 to facilitate the opening of the corresponding ventilation hole 13.

[0029] The portion of the cover plate 6 that extends beyond the housing 1 is arranged horizontally or tilted downward. The portion of the cover plate 6 that extends beyond the housing 1 allows the hot air to be further diffused to the surrounding areas. Specifically, when the hot air flows out of the first ventilation holes 11, part of the hot air flows upward. At this time, the portion of the cover plate 6 that extends beyond the housing 1 can further block the upward-flowing hot air, allowing the hot air to flow to the surrounding areas under the action of the lower end surface of the cover plate 6.

[0030] The utility model further comprises an air heater with uniform air flow, which is located between the heating element 3 and the tapered guide plate 5. The outer diameter of the air heater 7 is consistent with the inner diameter of the housing 1 and is located directly above the heating element 3. During installation, the air heater 7 can be positioned by mounting the air heater 7 on a protrusion formed on the inner wall of the housing 1.

[0031] The wind guide wheel 7 includes an outer peripheral plate 71 and multiple guide plates 72. The outer peripheral plate 71 is located outside the guide plates 72. Adjacent guide plates 72 form air guide openings 73 between the outer peripheral plate 71. The bottom diameter of the air guide openings 73 is smaller than the top diameter. The outer peripheral plate 71 and the guide plates 72 are integrally formed. The air guide openings 73 guide the hot air, allowing the heat generated by the heating element 3 to gradually diffuse to the surrounding area along the air guide openings 73. This evenly distributes the heat above the wind guide wheel 7, improving the uniformity of the heat dissipation to the surrounding area.

[0032] The outer periphery of the housing 1 is provided with a second ventilation hole 12, which is located between the simulated flame cover 2 and the fan 4, and the simulated flame cover 2 is located at the bottom of the housing 1. Therefore, outside air can enter through the second ventilation hole 12, facilitating the upward flow of air under the action of the fan.

[0033] The utility model further comprises a bottom cover 8, which is provided on the bottom end of the shell 1, and the simulated flame cover 2 is bonded or fixed to the bottom cover 8 by screws. When assembling, the simulated flame cover 2 is first assembled with the bottom cover 8, and then the bottom cover 8 is matched with the shell 1.

[0034] The bottom cover 8 has a groove 81 that fits into the bottom end of the outer shell 1. The width of the groove 81 matches the thickness of the bottom end of the outer shell 1. To mate the outer shell 1 with the bottom cover 8, the bottom end of the outer shell 1 is inserted into the groove 81 and then secured with screws. The fit of the groove 81 with the outer shell 1 allows for quick and secure engagement of the bottom cover 8 with the outer shell 1.

[0035] A heater with uniform air flow also includes an adjustment button 9, which is located on the outside of the housing 1 and is electrically connected to the heating element 3 via a wire. Controlling the on / off state of the heating element 3 and the operating power of the heating element 3 via the adjustment button 9 is a common technique used in existing heaters, and the specific control principles will not be described in detail here. The provision of the adjustment button 9 facilitates control over the operating conditions of the heating element 3, making it easy to use.

[0036] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
