Embodiment 1

[0035] Embodiment 1 of the present invention provides a control method for an electric heater, which is applied to a radiation and convection electric heater. figure 1 It is a schematic flow chart of the electric heater control method in Embodiment 1 of the present invention, as figure 1 As shown, the control method of the electric heater in Embodiment 1 of the present invention includes the following steps:

[0036] S101: Obtain the distance between the electric heater and the user.

[0037] As a specific implementation manner, a distance sensor may be used to obtain the distance between the electric heater and the user.

[0038] S102: Obtain a target temperature and a real-time temperature of the current environment, and calculate a temperature difference between the target temperature and the real-time temperature.

[0039] As a specific implementation manner, a temperature sensor may be used to acquire the real-time temperature of the current environment. The target tem...

Embodiment 2

[0044] Embodiment 2 of the present invention provides a method for controlling an electric heater. figure 2It is a schematic flow chart of the electric heater control method in Embodiment 2 of the present invention, as figure 2 As shown, the control method of the electric heater according to Embodiment 2 of the present invention includes the following steps:

[0045] S201: Obtain the distance between the electric heater and the user.

[0046] S202: Obtain a target temperature and a real-time temperature of the current environment, and calculate a temperature difference between the target temperature and the real-time temperature.

[0047] S203: Input the distance and the temperature difference into a preset power control function to obtain the heating power of the electric heater.

[0048] In the embodiment of the present invention, the power control function may be expressed as P=Φ(ΔT, L). As a specific implementation manner, the power control function is a piecewise fun...

example 1

[0054] Among them, Example 1 includes the following steps:

[0055] Step 11: Obtain the distance L=1m between the electric heater and the user;

[0056] Step 12: Obtain the target temperature and the real-time temperature of the current environment, and calculate the temperature difference between the target temperature and the real-time temperature ΔT=15-20°C;

[0057] Step 13: Input ΔT=15-20°C, L=1m into the preset power control function P=Φ(ΔT, L) to obtain the heating power of the electric heater as 2000W (third gear).

[0058] Step 14: Input △T=15~20℃, L=1m into the preset air volume control function Q=f(△T, L) to get the air supply air volume of the electric heater to be 120m 3 / h (fourth gear).

[0059] It can be seen that in Example 1, when the difference between the real-time indoor temperature and the target temperature △T=15~20℃, L=1m, the above method can achieve high power (2000W) and large air volume (120m 3 / h) output. When the radiant convection electric he...

Abstract

The invention discloses a control method and device of an electric heater, the electric heater and a storage medium. The control method comprises the following steps: acquiring the distance between the electric heater and a user; acquiring a target temperature and a real-time temperature of a current environment, and calculating a temperature difference between the target temperature and the real-time temperature; and calculating the heating power and the air supply quantity of the electric heater according to the distance and the temperature difference. The change of the radiation heat transfer amount and the convective heat transfer amount is caused by the change of the heating power and the air supply quantity, so that the radiation heat transfer amount and the convective heat transferamount of the radiation convection type electric heater are automatically adjusted according to different use environments and use requirements, different use conditions are met, and meanwhile, the heat utilization efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a control method and device for an electric heater, an electric heater and a storage medium. Background technique [0002] In order to improve the urban environment and reduce pollution caused by coal-fired heating, many cities encourage the use of clean energy such as natural gas and electricity for heating, and vigorously promote the "coal-to-electricity" project of decentralized heating. Electric heating is clean and pollution-free, in line with the national "energy saving, The policy orientation of "low carbon and environmental protection" has attracted more and more people's attention and has broad application prospects. [0003] According to the heating principle, electric heaters can be divided into convection electric heaters, radiant electric heaters and radiant convective electric heaters. Among them, convection heaters use convection heating, and ...
