Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Fig. 1 shows a flowchart of an electric heater control method according to an embodiment of the present invention, it should be noted that, in the embodiment of the present invention, a target object is taken as an example for description, and in practical applications, the target object may also be equipment or animals with heating requirements, and the present invention is not limited thereto. As shown in fig. 1, the method for controlling the electric heater specifically includes the following steps:
step S101: position signals and temperature signals of the target object are acquired respectively.
Specifically, in an embodiment, the position signal and the temperature signal may be obtained by a signal acquisition device disposed outside the electric heater, for example: the infrared human body detection sensor can be arranged outside the electric heater to collect position signals of a human body and temperature distribution signals on the surface of the human body, and then the temperature distribution signals are converted into temperature signals through the temperature sensor connected with the infrared human body detection sensor.
Step S102: and determining the position direction of the target object according to the position signal. In practical application, when the electric heater works, if a human body is sitting right in front of the electric heater, the shielding area of the body part of the human body on an electric heating diaphragm arranged in the electric heater is large, at the moment, an induction signal received by the infrared human body detection sensor is strong, and the induction signal is processed by a processor in the electric heater to determine that the position of a user is right in front of the electric heater; if the human body does not sit in the dead ahead of electric heater, the assumption is located the both sides 45 degrees positions of electric heater, then the sensing signal that foretell human detection sensor of infrared formula received is weaker, handles with the position of confirming the user for being located the both sides of electric heater through the treater in the electric heater.
Step S103: and judging whether the temperature signal of the target object exceeds a preset temperature threshold value. Specifically, the preset temperature threshold is a comfortable body surface temperature value of the body surface of the human body, and may be set according to actual needs, which is not limited in the present invention. In practical application, when the user just got into when indoor adoption electric heater keeps warm, human body feeling temperature is lower, hope straight face electric heater air outlet heating rising body temperature as early as possible this moment, and after user's heating a period, along with human body surface temperature's rising, if continue the air outlet of straight face electric heater will cause human body surface temperature to rise too high and cause human uncomfortable sense, consequently whether the temperature signal through judging foretell target object surpasss and predetermines the temperature threshold value and carry out automatic control to the air-out direction and the mode of operation of electric heater.
Step S104: if the temperature signal of the target object does not exceed the preset temperature threshold, the air outlet direction of the electric heater is controlled to face the position direction of the target object. In practical application, if the body surface temperature of the human body is lower than the preset temperature threshold value, it is indicated that the user's demand is as soon as possible to heat in order to improve the surface temperature of the human body, and at this moment, the air-out direction of the electric heater is controlled to enable the body surface temperature of the user to be improved at the fastest speed towards the position where the user is located, so that the experience and comfort of the user are improved. For example: when the user is sitting in the dead ahead of electric heater, then each electric heating diaphragm in this electric heater of control is in horizontal position and heats, when the user is located the non-dead ahead of electric heater for example when both sides 45 degrees, then control each electric heating diaphragm rotation 45 degrees in this electric heater, heat towards human position direction, thereby guarantee that each electric heating diaphragm is all the time with the maximum area to user radiant heat, thereby realized improving user's body surface temperature's effect fast, strengthen user's heating experience, through the radiation angle of increase electric heater horizontal direction, heating and human activity range have been increased, realize more nimble local heating effect and adjust. Meanwhile, the air flow diffusion and heating effects in the horizontal direction are enhanced.
Step S105: if the temperature signal of the target object exceeds the preset temperature threshold value, the air outlet direction of the electric heater is controlled to rotate by taking the position direction of the target object as the center. In practical application, if the body surface temperature of a human body reaches or exceeds a preset temperature threshold, it is indicated that the body surface temperature of the user reaches a heating effect at the moment, and the user wants the body surface temperature to be maintained at about the preset temperature threshold, so that the heating effect is ensured and the comfort of the human body temperature feeling is also maintained at the same time. Thereby through each electric heating diaphragm of periodic rotation for can produce the disturbance to the inside flow field of electric heater, form the hot gas flow of perpendicular to blade direction of rotation, strengthened the ascending air current diffusion of horizontal direction, both guaranteed user's heating effect, also can not make the user because feel the discomfort that the body surface temperature is too high and arouse, reach the local heating effect of optimal.
Through the steps S101 to S105, according to the electric heater control method provided by the embodiment of the present invention, the position signal and the temperature signal of the target object are obtained, the position direction of the target object is determined according to the position signal, whether the temperature signal exceeds the preset temperature threshold value is determined, if the temperature signal does not exceed the position direction of the target object, the air outlet direction of the electric heater is controlled to rotate around the position direction of the target object, and if the temperature signal exceeds the preset temperature threshold value, the air outlet direction of the electric heater is controlled to rotate around the position direction of the target object, so that the air outlet direction and the rotation of the electric heater are automatically controlled according to the position signal and the temperature signal of the target object, which is simple and convenient, and enables user experience to be more intelligent, the. Thereby can be according to human different positions automatically regulated mode, control electric heat diaphragm rotates, realize intelligent companion's heating, adopt the radiating mode of radiation and natural convection, it is comfortable to keep warm to improved the direct come-up of current electric heater hot gas flow, the horizontal direction hot gas flow diffusion is weak, the problem that local heating effect is not good.
The following describes the electric heater control method provided by the embodiment of the present invention in detail with reference to specific application examples.
In this application example, the electric heating membranes arranged in the electric heater are divided into two groups, and the two groups of electric heating membranes can be controlled respectively.

In addition, the electric heating film is equivalent to a rotating blade, and can generate disturbance to the internal flow field of the electric heater, so that hot air flow perpendicular to the rotation direction of the blade is formed, and air flow diffusion in the horizontal direction is enhanced. Compared with the existing electrothermal film electric heater, the electric heater control method provided by the embodiment of the invention can automatically adjust the working mode according to different positions of a human body, control the rotation of the electrothermal film, increase the horizontal radiation angle of the electric heater, increase the heating and human body activity range and realize more flexible local heating effect adjustment.
