step S3: if the outlet air temperature t is greater than or equal to the first temperature threshold value and less than the second temperature threshold value, the power supply between the electric heater 100 and the electric device 200 is cut off.
As shown in fig. 2 and 3, the electric heater 100 includes a housing 1, a fixing bracket 11 disposed in the housing 1, four heating wires 12, and a temperature sensing device 13, wherein the four heating wires 12 and the temperature sensing device 13 are respectively fixed on the fixing bracket 11, and the temperature sensing device 13 is disposed opposite to the four heating wires 12. The temperature sensing device 13 includes a temperature sensor and a metal housing, such as a stainless steel housing, covering the outer circumference of the temperature sensor for detecting the temperature of a predetermined location.
In this embodiment, the temperature sensing device 13 is used for detecting the air outlet temperature t of the electrical equipment 200, so as to ensure that the user can clearly and intuitively know the air outlet temperature t through temperature display, and the user can manually control the operation state of the electric heater 100 according to the comfort level of the user. For example, when the protection device of the electric heater 100 fails, the user finds that the temperature exceeds the standard, and can manually turn off the electric heater 100 to ensure that no safety accident occurs. If this function is not required, the temperature sensing device 13 may be short-circuited or the temperature sensing device 13 may not be connected. If the temperature sensing device 13 detects an open circuit or a short circuit, the electric heater 100 cannot be activated.
The electrical equipment 200 can be electrical equipment such as an air conditioning unit and a wall-mounted furnace, and the electrical heater 100 can be used independently of the electrical equipment 200, and when the heating effect of the air conditioning unit or the wall-mounted furnace installed in the home of a user is poor, the electrical heater 100 can be purchased independently for household heating. For convenience of explanation, the embodiment of the present application will be described taking the electrical apparatus 200 as an air conditioning unit.
Specifically, when the heating effect of the air conditioning unit is poor, the heat pump and the electric heater 100 of the air conditioning unit are started at the same time; the air outlet temperature t of the air conditioning unit is obtained through a temperature sensing device 13 arranged in the shell 1 of the electric heater 100; if the air outlet temperature t meets the following conditions: and T1 is less than or equal to T < T2, cutting off the power supply between the electric heater 100 and the electrical equipment 200. The temperature interval formed by the first temperature threshold T1 and the second temperature threshold T2 is determined by the user according to the comfort of the user, when the air outlet temperature T detected by the temperature sensing device 13 is located in the temperature interval, it is indicated that the user body senses that the temperature is hot, the first re-protection mechanism of the electric heater 100 starts to act, a temperature signal is transmitted to the air conditioning unit, the power supply between the electric heater 100 and the electrical equipment 200 is cut off, the purpose of turning off the electric heater 100 is achieved, and the optimal comfort temperature of the user can be achieved only through heating by the heat pump. The linkage protection mechanism of the air conditioning unit and the electric heater 100 can be triggered before the self-protection of the electric heater 100 is started, so that the absolute safety effect is achieved, and the use cost of the electric heater 100 is effectively reduced.
According to the temperature control method for the electric heater, the temperature sensing device 13 is arranged in the shell 1 of the electric heater 100 to monitor the air outlet temperature T of the electric appliance 200, so that real-time linkage of the electric heater 100 and the electric appliance 200 can be realized, and when the air outlet temperature T is greater than or equal to the first temperature threshold T1 and less than the second temperature threshold T2, the power supply between the electric heater 100 and the electric appliance 200 is cut off, namely, the electric heater is triggered before self-protection of the electric heater 100 is started, the use cost of the electric heater 100 is effectively reduced, the safety of the electric heater 100 is improved, and the comfort level of a user is improved.
In some embodiments, the electric heater 100 further comprises a relay 14, the relay 14 being electrically connected to the plurality of sets of heating wires 12, the temperature control method further comprising:
step S4: if the outlet air temperature t is greater than or equal to the second temperature threshold value, the relay 14 is controlled to be powered off so as to cut off the power supply of the heating wire 12.
In this embodiment, if the air outlet temperature t detected by the temperature sensing device 13 satisfies the following conditions: t is greater than or equal to T2, which indicates that the linkage mechanism of the electric heater 100 fails, and at the moment, the second protection mechanism can be started, namely, the action of the relay 14 of the electric heater 100 is controlled to trigger protection, and the power supply of the plurality of groups of heating wires 12 is cut off by controlling the power failure of the relay 14. When the air outlet temperature T is lower than the second temperature threshold T2, the relay 14 can be automatically reset, the electric heater 100 cannot be damaged, and after the relay 14 is reset, the circuit of the electric heater 100 is conducted, so that the electric heater can be continuously used, and the use cost of the electric heater 100 is further reduced.
Further, the electric heater 100 further includes a fuse link 15 electrically connected to the heating wires 12, and if the relay 14 is damaged, the fuse link 15 is fused to power off the plurality of groups of heating wires 12.
In this embodiment, if the control of the relay 14 fails due to the reason of too high temperature, a third protection mechanism may be started at this time, that is, the fuse link 15 of the electric heater 100 will automatically blow, the circuit of the electric heater 100 is cut off, the fuse link 15 fuses to be non-self-resetting protection, at this time, the heating wire 12 may be damaged, and the electric heater 100 cannot work normally. Compared with the technical scheme that the electric heater 100 can be completely cut off only once only by the fuse link 15 of the electric heater in the related art, the embodiment adopts a triple protection mechanism, so that the use safety of a user is protected to the greatest extent, and the potential safety hazard is greatly reduced.

In this embodiment, the electric heater 100 may be started and disconnected in a grading manner according to a set temperature profile, when all the heating wires 12 are powered on and started, the temperature may reach a maximum value, and when only part of the heating wires 12 are powered on and started, the temperature may be regulated in a grading manner. In practical use, the air conditioning unit may be directly provided with the electric heater 100 with maximum power, and when a user does not need a higher temperature, for example, T is greater than or equal to T3, and T3 is less than T1, the air conditioning unit may be controlled according to a set manner, for example, only 2 or 3 groups of heating wires 12 of the 4 groups of heating wires 12 are started to perform heating. If the user deems the temperature at which the 2 sets of heating wires 12 are activated to be low, the 4 sets of heating wires 12 may be set to the full on mode. And vice versa, the electric heater 100 can be started and disconnected in a grading manner by controlling the number of the starting groups of the heating wires 12, so that the aim of saving energy is fulfilled while the comfort of a user is ensured.
In some embodiments, the temperature control method further comprises:
step S6: if the outlet air temperature T is greater than the fourth temperature threshold T4, only the electrical device 200 is started, wherein the fourth temperature threshold T4 is smaller than the third threshold T3.
In this embodiment, if the air outlet temperature t detected by the temperature sensing device 13 satisfies the following conditions: when T is more than or equal to T4 and T4 is less than T3, the electric heater 100 is not required to be started, and the air conditioning unit heats by means of the heating capacity of the self heat pump, so that the comfort requirement of a user can be met.
Of course, when the outlet air temperature satisfies the following conditions: when T is less than or equal to T4 or T is less than or equal to T1, the air outlet temperature is lower, and the heat pump of the air conditioning unit and the electric heater 100 are required to be started simultaneously for temperature control, so that the aim of graded control at any time under different environmental temperature conditions is fulfilled, potential safety hazards are reduced, and the use cost of the electric heater 100 is reduced.
Therefore, according to the temperature control method of the electric heater provided by the embodiment of the application, the temperature sensing device 13 is arranged in the shell 1 of the electric heater 100, so that a user can monitor the air outlet temperature of the electric appliance 200 in real time, and the use state of the electric heater 100 is adjusted in a grading manner according to the comfort of the user, so that the optimal comfort temperature of the user is achieved; the linkage protection mechanism of the electrical equipment 200 and the electric heater 100 can trigger before the self-protection of the electric heater 100 is started, so that the absolute safety effect is achieved, and the use cost of the electric heater 100 is effectively reduced; the control logic sequentially adopts a triple protection mechanism for cutting off the power supply between the electric heater 100 and the electrical equipment 200, cutting off the power supply of the plurality of groups of heating wires 12 by cutting off the power supply of the relay, and fusing the fuse link 15 of the electric heater 100 to cause the plurality of groups of heating wires 12 to be powered off and fail, thereby protecting the use safety of users to the maximum extent and greatly reducing the potential safety hazard.
