Some equipment that has not been turned on cannot be turned on due to the low ambient temperature. The temperature at the personnel location is difficult to control and the comfort level is extremely poor.

[0033] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] In a preferred embodiment 1 of the present invention, a control method for an electric heating device is provided, and the control method can be directly applied to an electric heating device with upward and downward air outlets. Figure 1 An optional structural schematic diagram of an electric heating device is shown. Figure 1 For the left view, Figure 1 As shown, the electric heating device provided by the present invention comprises:

[0036] An upper fan 1 and a lower fan 2, wherein the upper fan 1 comprises an upper crossflow fan blade and an upper PG motor, and the lower fan 2 comprises a lower crossflow fan blade and a lower PG motor;

[0037] The upper PTC electric heater 3 (upper heating element) and the lower PTC electric heater 4 (lower heating element) are used for heating;

[0038] The upper air outlet unit and the lower air outlet unit are respectively provided with an air outlet frame with adjustable wind direction. According to the difference in human body's perception of temperature, the temperature requirements of different areas can be met by adjusting the angle of the air outlet frame. The air outlet frame includes: an upper air outlet frame 5 and a lower air outlet frame 6;

[0039] like Figure 1 As shown, the electric heating device is also provided with an upper air outlet temperature sensing package 7, a lower air outlet temperature sensing package 8, an electrical box 9, and an ambient temperature temperature sensing package 10;

[0040] In addition, it also includes the rear panel, front panel and other parts. The return air vent is designed on the front panel, and the arrow direction is the air inlet direction.

[0041] The upper and lower fans are the same PG motors, each with 3 gears. The upper and lower crossflow blades are used to increase the air volume of the unit. The upper and lower PTC electric heaters are the same PTC electric heaters. The fan and electric heater are controlled separately by the drive board. The heating capacity of the PTC electric heater will change with the wind speed flowing through the surface. The greater the wind speed flowing through the surface, the greater the heating capacity of the PTC electric heater. Since PTC electric heaters are used to generate heat, the heat generation is closely related to the wind speed flowing through the PTC surface. Therefore, corresponding control strategies are used at different wind speeds to maintain the same air outlet temperature and achieve the best air supply effect.

[0042] When the electric heating device is working, the upper and lower fans and PTC electric heaters can be adjusted separately. The speed of the upper and lower fans can be adjusted separately through the control system, and the upper and lower PTC electric heaters can be controlled in multiple gears. The gear control can be combined with the air volume and the detected air outlet temperature to achieve the purpose of controlling the air outlet temperature.

[0043] The return air outlet is set on the front panel, and the air only needs to be returned from the front of the unit, so it can be used in a narrow environment. The indoor return air enters from the front panel, and there is an electrical box in the middle to divide the air into two paths, which pass through the upper and lower PTC electric heaters for heat exchange, and then pass through the upper and lower crossflow fan blades to be blown out from the upper and lower air ducts respectively. The air outlet needs to be away from the front panel opening so that the air outlet has a certain angle, improves the air supply effect, solves the problem of uneven distribution of indoor temperature field, and improves the uniformity of indoor temperature.

[0044] At the same time, the electrical box is placed in the middle of the unit, which plays the role of separating the upper and lower air ducts. Under the action of the fan to make the air flow, the wind directly takes away the heat on the surface of the electrical box, so there is no risk of high temperature when the electrical box is placed in the middle of the unit.

[0045] The electric heating element adjusts the heating value according to the control instruction, controls the upper and lower air outlet temperatures, and realizes temperature regulation. The control method for adjusting the heating value is mainly to collect the ambient temperature data using the temperature sensing package installed near the air inlet, and calculate the optimal air outlet temperature of the upper and lower air outlets in combination with the temperature value set by the user, determine the power of the electric heating element, and realize the precise control of the upper and lower air outlet temperatures respectively through two sets of electric heating element control systems.

[0046] For the control of the fan, the control module performs real-time processing and analysis, determines the adjustment direction of the fan speed according to the difference between the ambient temperature and the set value, outputs instructions to control the motor speed, and automatically adjusts the air volume to maintain a uniform distribution of indoor temperature.

[0047] The wind direction can be adjusted by adjusting the angle of the air outlet frame to avoid strong wind blowing directly on the human body and making the user feel uncomfortable. At the same time, the air outlet temperature and air volume can be automatically adjusted to maintain a uniform distribution of indoor temperature and improve user comfort.

[0048] Figure 2 The front view of the electric heating device is shown, and the location of the electrical box is shown, such as Figure 2 As shown in , the electrical box is arranged in the middle of the air inlet.

[0049] Based on the above electric heating device, a control method for an electric heating device is provided in a preferred embodiment 1 of the present invention. Specifically, Figure 1 An optional flow chart of the method is shown as follows: Figure 1 As shown, the method includes the following steps S302-S306:

[0050] S302: Detecting the ambient temperature of the electric heating device;

[0051] S304: Determine an operation mode of the electric heating device according to the ambient temperature; wherein the operation mode includes at least: a normal temperature operation mode and a low temperature operation mode;

[0052] S306: Control the operation of the fan, the air outlet unit and the heating element according to the operation mode.

[0053] In the above embodiment, an upper and lower air outlet electric heating device and an electric heating device control scheme are provided. The electric heating device is provided with upper and lower air outlets. Each air outlet is provided with a fan, an air outlet frame and a heating element for adjusting the air volume, air outlet angle and air outlet temperature of each air outlet, so as to achieve separate adjustment of the upper and lower air outlets, and effectively solve the problem that the air outlet mode of the air outlet of the electric heating device in the prior art is fixed and cannot be flexibly adjusted. And the operating mode of the electric heating device is determined by detecting the ambient temperature of the electric heating device, and the operation of the electric heating device is controlled according to the operating mode of the electric heating device. Corresponding control schemes are set for different operating modes, so that the air outlet of the electric heating device meets the air outlet requirements under different operating modes, improves the flexibility of the control of the electric heating device, makes the applicability and comfort of the electric heating device better, and increases the control accuracy, thereby improving the overall performance of the electric heating device.

[0054] Specifically, the operation mode of the electric heating device is determined according to the ambient temperature, including: judging whether the ambient temperature is lower than the preset low temperature; if so, determining that the operation mode of the electric heating device is the low temperature operation mode; otherwise, determining that the operation mode of the electric heating device is the normal temperature operation mode. For example, when the ambient temperature is above -10°C, the electric heating device operates in the normal temperature operation mode. When the ambient temperature is lower than -10°C, the electric heating device operates in the low temperature operation mode. By judging the ambient temperature, the operation mode of the electric heating device is adjusted so that the operation mode of the electric heating device is adapted to the environment and the function of the electric heating device is fully utilized. Based on the purpose of different operation modes, different controls are performed in different operation modes, so as to achieve the control objectives of each operation mode, achieve the effect of intelligent control, and improve the comfort of users and the intelligence of the electric heating device.

In the startup stage, the gears of the electric heating element and the fan are determined according to the ambient temperature, and fully preheated to prepare for the subsequent operation stage.

[0077] S412: When T 设定 +1℃≤T 环境 When the unit is in standby mode, the electric heating element and the fan are not started to avoid overheating of the indoor temperature.

[0078] Based on the different ambient temperatures, the fan gear and the air outlet frame angle are adjusted accordingly. The lower the ambient temperature, the higher the fan gear and the larger the air outlet frame angle are required. Based on the principle of hot air sinking, the lower air outlet frame angle can be made larger than the upper air outlet frame angle, so that the uniformity of the indoor wind field is improved, the problem of uneven air outlet is avoided, the effect of natural wind is achieved as much as possible, and the user's comfort is improved. Electric heating is controlled in multiple gears, and the electric heating gear is automatically adjusted by the control system. The system detects the fan speed and air outlet temperature, and automatically adjusts the gear by comparing the set temperature. The user only needs to adjust the set temperature.

[0079] In another preferred embodiment of the present invention, when the operation mode is the low-temperature operation mode, the operation of the fan, the air outlet unit and the heating element is controlled according to the operation mode, including: obtaining the set temperature of the electric heating device; when the electric heating device is in the startup stage, controlling the operation of the fan, the air outlet unit and the heating element; when the electric heating device is started and in the operation stage, detecting the return air temperature, and controlling the operation of the fan, the air outlet unit and the heating element according to the return air temperature. When the ambient temperature is lower than -10°C, the electric heater operates in the low-temperature operation mode to adapt to the ambient temperature and optimize the effect of the electric heating device. The control strategy is as follows:

[0080] When the electric heating device is in the startup stage, the operation of the fan, the air outlet unit and the heating element is controlled, including: controlling the upper electric heating element and the lower electric heating element to start the first preset gear; after the fifth preset time, the lower fan is controlled to start the highest gear, and the upper electric heating element is controlled to increase one gear, and the opening of the lower air outlet frame is adjusted downward to the preset maximum angle. For example, the upper and lower electric heating are both started, and the wind gear is the highest gear; after △t time (this time is the preset value of the control system, generally 10s to 30s), the lower fan is started, the wind gear is the highest gear, and the lower electric heating is turned to the highest gear, and the upper electric heating is increased by 1 gear (if the upper electric heating is only 2 gears, keep the opening at 1 gear); at the same time, the lower air outlet frame is adjusted to the maximum downward angle. By turning the motor to the highest gear and turning the electric heating to the highest gear, the air outlet temperature is not limited, so that the environment is heated up quickly, and the ambient temperature is increased as soon as possible. It is suitable for cold times such as winter, and the user's heating needs can be met as soon as possible.

[0081] When the electric heating device is turned on and is in the operation stage, the operation of the fan, the air outlet unit and the heating element is controlled according to the return air temperature, including: when the return air temperature is greater than the preset low temperature, the operation of the fan, the air outlet unit and the heating element is controlled according to the normal temperature operation mode; when the return air temperature is greater than the fifth preset temperature, the upper and lower fans are controlled to open to the highest gear, the upper and lower electric heating elements are controlled to open to the highest gear, and the upper air outlet frame is controlled to sweep the air, and the lower air outlet frame is opened to the preset maximum angle; wherein the fifth preset temperature is less than the preset low temperature. When the detected return air temperature is higher than -10°C, the control enters the aforementioned normal temperature operation mode and detects the return air temperature. When the return air temperature is lower than -10°C, the following control is entered: turn on the fan and electric heating. At this time, the state of the electric heating device can include the following two forms:

[0082] a. Lower fan high-end, lower electric heating high-end, lower air outlet frame maximum angle (fixed);

[0083] b. Upper fan high-grade, power-on heating high-grade, upper air outlet frame sweeping air;

[0084] Because the air in the lower and middle parts of the cabin (the height at which most electronic equipment is placed and the height at which personnel are located) has been rapidly heated during the startup phase, the upper air outlet frame sweeps the air, rapidly stirring the ambient air in the middle and upper parts, accelerating the upward movement of the hot air and rapidly increasing the ambient temperature in the middle and upper parts.

[0085] In another preferred embodiment of the present invention, the operation of the fan, the air outlet unit and the heating element is controlled according to the return air temperature, and further includes: when the return air temperature is within the temperature range consisting of the set temperature of the electric heating device and the preset temperature difference, every sixth preset time interval, the lower air sweep mode is operated to control the lower air outlet frame to sweep the air. 设定 -1℃≤T 回风 ≤T 设定 During the +1℃ period, the lower air outlet frame starts the air sweeping function for 10 minutes (settable) every 10 to 20 minutes. Through the above solution, the air in the lower part of the cabin (the height where most electronic equipment is arranged and the height of personnel) is stirred to improve the temperature uniformity.

[0086] Furthermore, controlling the operation of the fan, the air outlet unit and the heating element according to the operation mode also includes: running the upper sweep mode at every seventh preset time interval to control the upper air outlet frame to sweep the air; running the mixed air mode at every eighth preset time interval to control the upper air outlet frame and the lower air outlet frame to sweep the air at the same time; wherein, when the mixed air mode conflicts with the upper sweep mode, the mixed air mode is preferentially run. Because the return air of the electric heating device is the middle return air, although it is based on the mechanism of hot air floating up, according to the return air field conditions, there may be some dead zones in the upper space where no hot air passes for a long time. During normal operation, the upper air outlet frame turns on the sweep function for 15 to 20 minutes every t1 hour (which can be set to 0.5h to 1h) of the electric heating device. Every t2 hours of operation, the upper air outlet frame and the lower air outlet frame turn on the sweep function for 15 to 20 minutes at the same time.

[0087] When the above times overlap, the dual air sweep function is run first. The upper air outlet frame turns on the air sweep function without determining whether the upper electric heating is turned on. Through the above air sweep and mixed air modes, the cabin ambient air is fully stirred to eliminate heating dead corners.

[0088] In addition, when the cabin is unattended and only the upper electronic equipment needs to be turned on, the on-duty mode can be selected. In the on-duty mode, you can choose to turn on only the lower fan or only the upper fan. Through the on-duty mode, the hot air is fixedly blown to the upper or lower part to achieve local ambient temperature heating. In this mode, the sweep function only allows the current fan to run the sweep function, and the mixed air function is not turned on.
