Electric heating warmer

Abstract

The utility model relates to an electric heating warmer. The electric heating warmer comprises a shell; the electric heating wire is arranged in the shell; the first air inlet and the heat dissipation opening are formed in the top and the bottom of the shell respectively; the fan is arranged at the side end of the shell; the turbulent flow cover is arranged on the fan in a sleeving mode and located in the shell. A hot air inlet and a cold air inlet are formed in the top and the side end of the turbulent flow cover correspondingly. The turbulent flow cover is arranged on the fan, so that air sucked into the fan is mixed air of hot air and cold air, and compared with a traditional mode that only hot air generated by an electric heating wire is sucked, the mixed air of the hot air and the cold air can take away heat generated by a fan motor or a driving motor; and the problem that the temperature of the single side is too high due to the fact that heat in a shell of a traditional warmer from bottom to top inclines towards the side with the fan is effectively solved, the risk that a motor or a driving motor of the fan is burnt out is reduced, and the service life of the motor or the driving motor of the fan is prolonged.

Description

Technical Field

[0001] This application relates to electric heating devices, and more particularly to an electric heater. Background Technology

[0002] A heater is a device used for heating. Based on the different heating media and heating principles, it can be broadly classified into several categories: gas heating devices, electric heating devices, boiler heating devices, and electric wall-hung boiler heating devices.

[0003] Gas-fired heating equipment, boiler heating equipment, and electric wall-hung boiler heating equipment primarily use water as the heating medium, and are mainly used for heating in cold regions. Before heating is provided, and in some areas without heating, people often choose a common type of electric heating equipment, also known as an electric heater, such as... Figure 1 The electric heater shown is increasingly popular due to its small size, portability, and fast heating speed. When in use, it only needs to be powered on, and it can use the internal electric heating wire to heat the space and radiate the heat generated to the surrounding area for heating.

[0004] To quickly dissipate the heat generated by electric heaters into the surrounding space and rapidly raise the temperature, people gradually began to install fans on the outer casing of these heaters. After the heating element in the heater heats up, the fan also starts rotating, thus quickly dissipating the heat and raising the temperature of the surrounding space rapidly, achieving the purpose of rapid heating. However, as the electric heater is used for an extended period, the temperature of the fan's drive motor also increases. Furthermore, since the fan mainly exhausts hot air, the temperature of the drive motor will rise further, making it prone to burnout and reducing its lifespan. Summary of the Invention

[0005] To extend the service life of a fan's drive motor, this application provides an electric heater that incorporates a baffle on the fan, allowing the air drawn into the fan to be a mixture of hot and cold air. Compared to traditional heaters that only draw in hot air generated by the electric heating element, this mixture of hot and cold air effectively removes the heat generated by the fan motor or drive motor. Furthermore, it effectively solves the problem of heat rising from the bottom of the casing of traditional heaters and tilting towards the fan side, resulting in excessively high temperatures on one side. This reduces the risk of the fan motor or drive motor burning out and extends its service life.

[0006] This application provides an electric heater, which adopts the following technical solution:

[0007] An electric heater, comprising:

[0008] shell;

[0009] An electric heating wire, located inside the outer casing, is used to generate heat through electric heating.

[0010] The first air inlet is located at the bottom of the casing;

[0011] The heat dissipation vents are located on the top of the outer casing;

[0012] A fan, located on the side of the casing, is used to dissipate heat from inside the casing; and

[0013] The spoiler is fitted onto the fan and located inside the housing;

[0014] The spoiler has a hot air inlet at the top and a cold air inlet at the side, with the cold air inlet located on the side of the spoiler away from the electric heating wire.

[0015] Preferably, the fan includes a mounting bracket and a fan body, the mounting bracket being mounted on the housing and the fan body being mounted on the mounting bracket.

[0016] Preferably, the fan further includes a grid located at the air outlet of the fan body.

[0017] Preferably, the bottom of the outer casing is provided with support legs.

[0018] Preferably, the hot air inlet is provided with a grille.

[0019] Preferably, the housing has a baffle inside, the baffle is located below the spoiler, and the electric heating wire and the cold air inlet are located on both sides of the baffle.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. This application, by setting a baffle on the fan, makes the gas drawn into the fan a mixture of hot and cold air. Compared with the traditional method of only drawing in hot air generated by electric heating wire, the mixture of hot and cold air can carry away the heat generated by the fan motor or drive motor. It also effectively solves the problem of heat from bottom to top in the shell of traditional heaters tilting towards the side with the fan and causing excessively high temperature on one side, reducing the risk of the fan motor or drive motor burning out and extending the service life of the fan motor or drive motor.

[0022] 2. This application improves the efficiency of the cooling air intake by installing a baffle inside the housing, allowing the hot air and cold air mixture to better remove the heat generated by the fan motor or drive motor, thereby reducing the risk of the fan motor or drive motor burning out and extending its service life.

[0023] 3. This application reduces the risk of foreign objects being sucked into the hot air inlet by installing a grid plate at the hot air inlet, and reduces the risk of the fan being entangled by foreign objects during rotation. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an electric heater.

[0032] Example 1

[0033] Reference Figure 2 and Figure 3 The electric heater includes a shell 1, an electric heating wire 2, a fan 3, and a spoiler 4.

[0034] The bottom of the outer casing 1 is equipped with support legs 11, and the outer casing 1 can be configured as a cuboid shape.

[0035] The electric heating wire 2 is installed inside the outer casing 1, and the electric heating wire 2 is located at the bottom inside the outer casing 1. When the heater is placed on a horizontal surface, the electric heating wire 2 is distributed in a horizontal direction, and the electric heating wire 2 does not cover the bottom inside the outer casing 1. A notch with a distance of one end is reserved between one side of the electric heating wire 2 and the inner wall of the outer casing 1.

[0036] Reference Figure 2 and Figure 3 The bottom of the outer casing 1 has a first air inlet 12, and the electric heating wire 2 is located above the first air inlet 12. The top of the outer casing 1 has a heat dissipation vent 13, which is used to dissipate the heat generated by the electric heating wire 2. The first air inlet 12 and the heat dissipation vent are both grid-shaped to prevent debris from entering the outer casing 1 and improve the safety of the heater.

[0037] The fan 3 is mounted on the side of the housing 1, and the fan 3 can be located at the edge of the connection between the two ends of the housing 1. The housing 1 has mounting holes for mounting the fan 3. The fan 3 includes a mounting bracket 31 and a fan body 32. The mounting bracket 31 is fixedly installed in the mounting holes on the housing 1, and the fan body 32 is fixedly installed on the mounting bracket 31. The fan body 32 is used to expel the gas inside the housing 1, thereby expelling the heat generated by the electric heating wire 2 inside the housing 1, so as to rapidly raise the temperature of the space near the heater.

[0038] To prevent foreign objects or other debris from entering the outlet of the fan body 32, a grid 33 is installed at the outlet of the fan body 32. The grid 33 can prevent larger foreign objects from entering the fan body 32.

[0039] Reference Figure 2 and Figure 4 The spoiler 4 is mounted on the fan 3. Specifically, the spoiler 4 can be fixed to the mounting bracket 31 or the fan body 32 by bolts. The top of the spoiler 4 has a hot air inlet 41, and the side of the spoiler 4 has a cold air inlet 42. The cold air inlet 42 is located on the side of the spoiler 4 away from the electric heating wire 2. At the same time, a corresponding gap is reserved between the cold air inlet 42 and the inner wall of the outer shell 1 so that cold air can enter the cold air inlet 42. In this embodiment, cold air refers to air with a relatively lower temperature than the hot air entering the hot air inlet 41.

[0040] Meanwhile, in order to prevent debris from entering the main fan 3 and affecting its rotation, a grid plate 43 is provided at the hot air inlet 41 at the top of the spoiler 4, or the hot air inlet 41 at the top of the spoiler 4 is opened in a grid shape.

[0041] Reference Figures 2 to 4The operating principle of this embodiment is as follows: by installing a spoiler 4 on the fan 3, the hot air generated by the electric heating wire 2 rises upward during use. Then, under the power of the fan body 32, the hot air rising inside the outer casing 1 is drawn in by the hot air inlet 41 at the top of the spoiler 4, while the cold air inlet 42 draws in cold air at a lower temperature than the hot air inlet 41. The cold air and hot air then merge and are discharged through the fan body 32. The temperature of the gas after the cold air and hot air merge is slightly lower than the temperature of the hot air, thus reducing the temperature of the motor of the fan body 32 and reducing the risk of the motor burning out, thereby extending the service life of the heater.

[0042] Example 2

[0043] Reference Figure 5 In other feasible embodiments, in order to facilitate the entry of cold air into the cold air inlet 42, the heater also includes a baffle 5, which is installed on the inner wall of the outer shell 1. The electric heating wire 2 and the cold air inlet 42 are located on both sides of the baffle 5, and a cold air channel is formed between the baffle 5 and the inner wall of the outer shell 1. This allows the air entering the outer shell 1 through the first air inlet 12 to directly enter the cold air inlet 42 through the cold air channel, where it merges with the hot air generated by the electric heating wire 2 entering the hot air inlet 41. The air then passes through the fan body 32 together, thereby reducing the overall temperature of the air passing through the fan 3 and reducing the risk of the motor or motor of the fan 3 being burned out.

[0044] In this embodiment, by setting a baffle 5 inside the outer casing 1 to separate the electric heating wire 2 from the cold air inlet 42, the possibility of the cold air inlet 42 entering the hot air generated by the electric heating wire 2 is reduced, thus extending the service life of the heater.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
