Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to an electric heating device. Background Art

[0002] Heaters are common household appliances that can provide heat in low-temperature environments and raise indoor temperatures. Existing heaters primarily use infrared heating and convection heating. Infrared heating provides close-range heating and is relatively inexpensive, while convection heating allows for rapid, quiet heating.

[0003] In order to provide users with a good heating experience, some heaters in the existing technology combine the two heating methods. For example, for the patent with application number 202223395214.2 and the name of an electric heater with dual heating functions, users can turn on the convection heating function or the reflection heating function according to their needs, but the structural setting of the electric heater will affect the infrared irradiation range on the one hand, and affect the air circulation on the other hand, resulting in the convection heating effect and the reflection heating effect cannot reach the best, affecting the user's heating experience.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve at least one of the above problems in the prior art, that is, to solve the problem of poor heating effect of existing heaters, the present application provides an electric heating device, comprising:

[0006] a housing, wherein a receiving cavity is formed in the housing, an air inlet is provided at the bottom of the housing, and a first air outlet is provided at the top of the housing;

[0007] a radiation heating module, the radiation heating module being disposed in the accommodating cavity, the radiation heating module comprising a first heating tube and a reflective cover, wherein the first heating tube is located in front of the reflective cover;

[0009] The radiation heating module is located above the convection heating module, and the front side of the shell is provided with a light outlet relative to the radiation heating module and a second air outlet relative to the convection heating module.

[0010] When adopting the above technical solution, the heat radiation range of the radiation heating module is larger, which can give full play to its heating effect, achieve rapid heating, and improve the user's heating experience. In addition, since the density of cold air is greater than the density of hot air, the convection heating module can better heat the cold air and form convection when it is located below, and then the hot air enters the room from the first air outlet, but part of the hot air may be blocked by the radiation heating module when flowing upward. At this time, this part of the hot air can also enter the room through the second air outlet, thereby ensuring the heating effect of the convection heating module.

[0011] In the preferred technical solution of the above electric heating device, the air inlet is at least partially arranged obliquely; and / or

[0012] The first air outlet is at least partially arranged obliquely.

[0013] When adopting the above technical solution, setting the air inlet or the first air outlet obliquely is beneficial to increasing the air inlet and outlet area, ensuring that the convection heating module can fully exert its heating effect, thereby improving the user's heating experience.

[0014] In the preferred technical solution of the above electric heating device, the housing includes a front cover and a rear cover, the front cover is connected to the rear cover, and the top and bottom of the rear cover are arranged obliquely;

[0015] At least part of the air inlet is located at the bottom of the rear cover, and at least part of the first air outlet is located at the top of the rear cover.

[0019] The two mounting plates are both connected to the rear side of the housing.

[0020] In the preferred technical solution of the above electric heating device, the air inlet includes a plurality of elongated holes; and / or

[0021] The first air outlet includes a plurality of elongated holes; and / or

[0022] The second air outlet includes a plurality of circular holes.

[0023] In a preferred technical solution of the above electric heating device, a plurality of the first heating tubes and the reflector are provided, the plurality of the first heating tubes and the reflector are arranged vertically, and each first heating tube is located in front of the corresponding reflector; and / or

[0024] There are multiple second heating tubes, which are arranged vertically, and the heat sink is sleeved on the outer sides of the multiple second heating tubes.

[0025] When adopting the above technical solution, due to the power limitation of the electric heating equipment, when both the radiation heating module and the convection heating module are set to multiple, the user can selectively use only one heating method or use two heating methods at the same time while ensuring the heating effects of various heating methods.

[0026] In a preferred technical solution of the above electric heating device, the electric heating device further comprises a control panel, which is arranged on the front side of the housing; and / or

[0041] As mentioned in the background, heaters are common household appliances that can provide heat in low-temperature environments and raise indoor temperatures. Existing heaters primarily use infrared heating and convection heating. Infrared heating provides close-range heating and is relatively inexpensive, while convection heating allows for rapid temperature increases without generating noise.

[0042] In order to provide users with a good heating experience, some heaters in the existing technology combine the two heating methods. For example, for the patent with application number 202223395214.2 and the name of an electric heater with dual heating functions, users can turn on the convection heating function or the reflection heating function according to their needs, but the structural setting of the electric heater will affect the infrared irradiation range on the one hand, and affect the air circulation on the other hand, resulting in the convection heating effect and the reflection heating effect cannot reach the best, affecting the user's heating experience.

[0043] In order to solve the problem of poor heating effect existing in existing heaters, the present application provides an electric heating device, including a shell, a radiation heating module and a convection heating module. A accommodating cavity is formed in the shell, an air inlet is provided at the bottom of the shell, and a first air outlet is provided at the top of the shell. The radiation heating module is arranged in the accommodating cavity, and the radiation heating module includes a first heating tube and a reflective cover, and the first heating tube is located in front of the reflective cover. The convection heating module is arranged in the accommodating cavity, and the convection heating module includes a second heating tube and a heat sink, and the heat sink is arranged on the outside of the second heating tube. The radiation heating module is located above the convection heating module, and the front side of the shell is provided with a light outlet relative to the radiation heating module and a second air outlet relative to the convection heating module.

[0044] When adopting the above technical solution, the heat radiation range of the radiation heating module is larger, which can give full play to its heating effect, achieve rapid heating, and improve the user's heating experience. In addition, since the density of cold air is greater than the density of hot air, the convection heating module can better heat the cold air and form convection when it is located below, and then the hot air enters the room from the first air outlet, but part of the hot air may be blocked by the radiation heating module when flowing upward. At this time, this part of the hot air can also enter the room through the second air outlet, thereby ensuring the heating effect of the convection heating module.

[0045] Refer to the following Figures 1 to 6 , the electric heating device of the present application is described. Among them, Figure 1 A front view of the electric heating device of the present application; Figure 2 This is a diagram of the internal structure of the electric heating device of this application; Figure 3 A top view of the electric heating device of the present application; Figure 4 A bottom view of the electric heating device of the present application; Figure 5 This is a first installation diagram of the radiant heating module of the present application;

[0046] Figure 6 This is a second installation diagram of the radiant heating module of the present application.

[0047] like Figures 1 to 6As shown, in a preferred embodiment, the electric heating device includes a housing 10, a radiant heating module 20, a convection heating module 30, a control panel 60, a support portion 70, and a handle 80. The housing 10 defines a receiving cavity, in which the radiant heating module 20 and the convection heating module 30 are disposed. The control panel 60 is disposed on the front side of the housing 10, the support portion 70 is connected to the bottom of the housing 10, and the handle 80 has two ends rotatably connected to two sides of the housing 10.

[0048] Return to Reference Figures 1 to 4 The shell 10 includes a front cover 11 and a rear cover 12. The front cover 11 is connected to the rear cover 12. An air inlet 13 is provided at the bottom of the shell 10, and a first air outlet 14 is provided at the top of the shell. The top and bottom of the rear cover 12 are arranged obliquely. Part of the air inlet 13 and part of the first air outlet 14 are respectively provided at the bottom and top of the rear cover 12, and the air inlet 13 and the first air outlet 14 each include a plurality of long holes. The radiation heating module 20 is located above the convection heating module 30. The convection heating module 20 includes two first heating tubes 21 and two reflective covers 22. The two first heating tubes 21 and the two reflective covers 22 are arranged vertically, and each first heating tube 21 is located in front of a reflective cover 22. The convection heating module 30 includes two second heating tubes 31 and a group of heat sinks 32. The heat sink 32 is sleeved on the outside of the two second heating tubes 31. The housing 10 has a front side formed with a light outlet 16 facing the radiation heating module 20 and a second air outlet 15 facing the convection heating module 30 , and the second air outlet 15 includes a plurality of circular holes.

[0049] Continue reading Figure 5 and Figure 6 The electric heating device also includes two mounting plates 40, both connected to the rear cover 12. Both mounting plates 40 are provided with openings. Connecting plates 50 extend outward from both sides of the first heating tube 21 and the reflector 22. The connecting plates 50 on both sides of the first heating tube 21 and the reflector 22 can extend through the openings to connect the mounting plates 40. When installing the convection heating module 30, the first heating tube 21 and the reflector 22 can first be passed through a mounting plate 40 on each side, and then the two mounting plates 40 can be connected to the rear cover 12 using connectors.

[0050] In this embodiment, the user can selectively control the operation of the first heating tube 21 and the second heating tube 31 through the control panel 60. When the first heating tube 21 is in operation, it generates infrared radiation, and the reflective cover 22 can reflect the infrared light on its surface in a specific direction. The infrared light transfers heat into the room through the light outlet 16 on the front cover 11. When the second heating tube 31 is in operation, the heat generated by the second heating tube 31 is transferred to the heat sink 32. Because the density of cold air is greater than that of hot air, the heat sink 32 first heats the cold air at the bottom, and then the hot air spontaneously flows upward, forming convection, so that cold air continuously enters the interior of the housing 10 from the air inlet 13, and hot air continuously enters the room from the first air outlet 14. Because some hot air is blocked by the first heating tube 21 and the reflective cover 22 during its upward flow, thereby affecting the heating effect of the convection heating module 30, this part of the hot air can now enter the room through the second air outlet 15, thereby ensuring the heating effect of the convection heating module 30. In addition, the obliquely arranged air inlet 13 and the first air outlet 14 can increase the air inlet and outlet area, and the arrangement of the long holes of the air inlet 13 and the first air outlet 14 can also ensure that the air inlet and outlet are not obstructed, thereby further improving the heating effect of the convection heating module 30.

[0051] It should be explained that the specific setting of the shell 10 is not fixed. In an alternative embodiment, the top and bottom of the shell 10 can be set horizontally. In this case, the air inlet 13 and the first air outlet 14 are also set horizontally. In another alternative embodiment, the shell 10 can be set as an assembled shell. For example, the shell 10 can include a top cover, a base and four side panels. In this case, the upper and lower ends of the four side panels are respectively connected to the top cover and the base, and the four side panels are set opposite each other in pairs. Of course, when the front cover 11 and the rear cover 12 are set, the air inlet 13 can be set only at the bottom of the front cover 11 or the rear cover 12, and the first air outlet 14 can also be set only at the top of the front cover 11 or the rear cover 12. In addition, the specific settings of the air inlet 13, the first air outlet 14 and the second air outlet 15 are not fixed. Those skilled in the art can change their specific shapes and apertures according to needs. For example, the air inlet 13 and the first air outlet 14 are both set as round holes.

[0052] It should also be explained that the installation method of the radiation heating module 20 is not fixed, and those skilled in the art can change the installation method of the radiation heating module 20 according to their needs. In an alternative embodiment, the first heating tube 21 can be connected to the back cover 12 through the mounting plate 40, and the reflector 22 can be directly connected to the back cover 12. In another alternative embodiment, the two mounting plates 40 can be connected to the left and right sides of the shell 10 respectively. Of course, the connection method of the first heating tube 21 and the reflector 22 and the mounting plate 40 is not fixed. In an alternative embodiment, folding edges can be set on the left and right sides of the reflector 22. In this case, connecting holes can be opened on the two folding edges and the mounting plate 40, and the connection between the reflector 22 and the mounting plate 40 is achieved by passing a connecting piece through the connecting hole.

[0053] Those skilled in the art will appreciate that, in this embodiment, two first heating tubes 21 and two second heating tubes 31 are provided. When the user uses only radiation heating, the two first heating tubes 21 can be turned on simultaneously to ensure the radiation heating effect. Similarly, when the user uses only convection heating, the two second heating tubes 31 can be turned on simultaneously to ensure the convection heating effect. However, when using both radiation heating and convection heating, due to the power limitation of the electric heating equipment, one first heating tube 21 and one second heating tube 31 can be turned on to combine the advantages of the two heating methods for heating. However, this setting is not required, and those skilled in the art can change the number of the first heating tube 21 and the second heating tube 31 as needed, for example, setting the first heating tube 21 and the second heating tube 31 to one.

[0054] Those skilled in the art will also appreciate that, in this embodiment, the control panel 60 is disposed on the front side of the housing 10 to avoid affecting air circulation while ensuring a good user experience. However, this arrangement is not required. In an alternative embodiment, the control panel 60 can be disposed on the left, right, or top side of the housing 10. Furthermore, the handle 80 is not necessarily fixed. In an alternative embodiment, the rotatable connection between the handle 80 and the housing 10 can be omitted, or the handle 80 can be connected to the top side of the housing 10. In another alternative embodiment, the handle 80 can be omitted.

[0055] Those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of this application and to form different embodiments. For example, in the claims of this application, any of the claimed embodiments may be used in any combination.

[0056] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
