Description

Technical Field

[0001] The invention belongs to the field of electric heating, and in particular relates to an electric heater. Background Art

[0002] The skirting board electric heater has gradually become the leading product of heating equipment due to its many advantages such as fast heating effect, convenient use and small space occupation. The general structure of the skirting board electric heater includes front and rear shells, with air outlets designed above the front and rear shells and air inlets below. After power is turned on, the air around the internal electric heating tube is heated and rises, flowing out from the air outlet, while the surrounding cold air enters from the air inlet for replenishment. This cycle is repeated to increase the indoor temperature. The existing skirting board electric heaters in the industry are not high in height, but they are long in length, and there are still large space restrictions on the user's use site and environment.

[0003] There are also folding skirting board products on the market, which solve the problem of space limitations in usage scenarios. However, due to the concentration of heat in the folded state, the surface temperature of the appliance is too high. In order to meet the standard requirements, the overall power of the product is relatively low. Summary of the invention

[0004] The present invention aims to provide an electric heater to solve the potential safety hazard caused by the operation of two heating elements after the electric heater is folded.

[0005] To achieve the above purpose, the specific technical solution of the electric heater of the present invention is as follows:

[0006] An electric heater comprises at least two half shells which rotate relative to each other, and further comprises:

[0007] The distance detection module is installed on each half shell and collects the distance information of adjacent half shells;

[0008] The control module receives the distance information of the adjacent half shells and reduces the upper power limit of the heating element in the half shells as the adjacent half shells get closer.

[0009] Furthermore, it also includes a base, and one end of the half shell is rotatably connected to the base.

[0010] Furthermore, a rotating shaft is fixedly connected to the base, a rotating arm is formed on the half shell, and the rotating arm is rotatably connected to the rotating shaft.

[0011] Furthermore, the rotating shaft is cylindrical, and the rotating arm is annular and sleeved outside the rotating shaft.

[0012] Furthermore, the distance detection module is installed on the rotating arm. As the rotating arm rotates, the distance detection module detects the distance between corresponding points, thereby collecting distance information between adjacent half shells.

[0013] Furthermore, the distance detection module is an infrared distance sensor, which includes an emitter and a receiver respectively mounted on two rotating arms.

[0014] Furthermore, the rotating arm forms an annular groove, the lower ends of the emitter and the receiver are respectively fixed in the corresponding annular grooves, and the upper ends extend out of the annular grooves.

[0015] Furthermore, an upper and a lower connecting sleeve are formed on the base, and the connecting sleeve is coaxially arranged on the outer side of the rotating shaft.

[0016] Furthermore, the two connecting sleeves are respectively located on both sides of the axial direction of the rotating arm, and the outer wall of the connecting sleeve is flush with the rotating arm.

[0017] Furthermore, two half shells are provided, and as the two half shells rotate relative to each other, the side surfaces of the two half shells fit each other.

[0018] The electric heater of the present invention has the following advantages: as the adjacent half shells are brought closer together, the upper limit of the power of the heating element in the half shells is reduced, thereby eliminating the potential safety hazard caused by the high-power operation of the two heating elements after the electric heater is folded.

[0023] In order to better understand the purpose, structure and function of the present invention, an electric heater of the present invention is further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the electric heater of the present invention is a baseboard electric heater, comprising a base 1. Figure 2 As shown, two half shells 6 are rotatably connected to the base 1, so that the skirting board heater can be folded in half by rotating the two half shells 6, so that the skirting board heater can be stored easily.

[0025] In order to prevent potential safety hazards from occurring when the two half shells 6 are brought close together, the upper limit of the power of the heating element in each half shell 6 needs to be reduced as the adjacent half shells 6 are brought close together. Therefore, a control system needs to be provided to achieve the above function.

[0026] A rotating shaft 2 is fixedly connected to the base 1 , and a rotating arm 3 fixedly connected to one end of a half shell 6 is rotatably connected to the rotating shaft 2 ; the rotating shaft 2 is columnar, and the rotating arm 3 is annular and sleeved outside the rotating shaft 2 .

[0027] In order to detect the distance, the electric heater is also provided with a distance detection module.

[0028] The distance detection module is installed on each half shell 6 and collects the distance information of adjacent half shells 6;

[0029] The control module receives the distance information of the adjacent half shells 6 and reduces the upper power limit of the heating element in the half shells 6 as the adjacent half shells 6 get closer.

[0030] In this way, the upper limit of the power of the heating element is adjusted according to the distance between the two half shells 6. When the two half shells 6 are folded in half, the heating element is automatically controlled to be close or even closed through the control module to ensure safety.

[0031] In order to prevent the distance detection module from being damaged, the distance detection module is installed on the rotating arm 3 . As the rotating arm 3 rotates, the distance detection module detects the distance between corresponding points, thereby collecting distance information between adjacent half shells 6 .

[0032] Generally, the distance detection module is an infrared distance sensor 4, which includes an emitter 41 and a receiver 42 respectively mounted on two rotating arms 3. The rotating arms 3 form an annular groove, and the lower ends of the emitter 41 and the receiver 42 are respectively fixed in the corresponding annular grooves, and the upper ends extend out of the annular grooves to form a continuous light path.

[0033] For example, when the angle between the adjacent half shells 6 is 180°, the distance between the two sensors is the minimum distance I; when the angle between the adjacent half shells 6 is 0°, the distance between the two sensors is the maximum distance L. When the distance between the two sensors is greater than I and less than 2I, the whole machine runs at full power. When the distance between the two sensors is greater than 2I and less than 0.5L, the duty cycle is adjusted to run at medium power. When the distance between the two sensors is greater than 0.5L and less than L, the whole machine runs at low power.

[0034] The base 1 is formed with an upper and a lower connecting sleeve 5, which are coaxially arranged on the outside of the rotating shaft 2; the upper and lower connecting sleeves 5 are respectively located on both sides of the axial direction of the rotating arm 3, and the outer wall of the connecting sleeve 5 is flush with the rotating arm 3. In this way, while ensuring the appearance, the infrared distance sensor 4 is built-in to avoid interference.

[0035] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
