Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, 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 invention provides a control method of a warm air blower, which is applied to the warm air blower. The air heated by the heating element is sent out from the air outlet of the warm air blower. The heating elements can be PTC (positive Temperature coefficient) electric heaters. The plurality of heating members can be independently operated, and when the number of the heating members to be turned on is larger, the heating amount per unit time is larger. Fig. 1 is a schematic flow chart of a fan heater control method according to the present invention. The warm air blower control method provided by the embodiment of the invention comprises the following steps:
s100, acquiring indoor environment temperature and air outlet temperature of an air outlet. The indoor ambient temperature sensor arranged at the air inlet of the warm air blower can detect the indoor ambient temperature, and the air outlet temperature sensor arranged at the air outlet of the warm air blower can detect the air outlet temperature.

When the warm air blower is started, all heating elements can be started according to a user control instruction or by default so as to accelerate the temperature rise. Or, the number of the heating elements to be started is determined according to the current indoor environment temperature so as to match the more proper heating quantity and avoid unnecessary energy consumption. For example, the number of the heating elements is 3, the target temperature of the indoor environment temperature is 30 ℃, and if the indoor environment temperature is less than 18 ℃, the temperature difference between the indoor environment temperature and the target temperature is large, all the three heating elements are turned on; if the indoor environment temperature is more than or equal to 18 ℃ and less than 23 ℃, only two heating elements are started; when the indoor environment temperature is more than or equal to 23 ℃ and less than 30 ℃, only one heating element is started.
S300, after the operation is carried out for a first preset time period, if the air outlet temperature is higher than a set air outlet temperature, calculating a difference value delta T between the air outlet temperature and the set air outlet temperatureC. Wherein the difference value DeltaTCThe set air-out temperature is the set air-out temperature.
S400, following the indoor environment temperature and the difference value delta TCUntil the number of the heating elements is reducedThe indoor ambient temperature is raised to the target temperature. Wherein the target temperature is a set target indoor environment temperature.
Specifically, after a set number of heating elements are started and the operation is carried out for a first preset time period, if the indoor environment temperature is higher than the target temperature, all the heating elements are closed; if the indoor ambient temperature does not reach the target temperature and the outlet air temperature is raised to be higher than the set outlet air temperature, calculating the difference value delta T between the set outlet air temperature and the outlet air temperatureC. Along with the rise of indoor environment temperature, the temperature of the surface of the heating element rises, the temperature of the air outlet rises, and the difference value delta TCAnd gradually increases. The temperature of the room is gradually increased and the difference value delta TCIn the process of gradual increase, the opening number of the heating elements is properly reduced, and the indoor environment temperature is ensured to be generally still in an increasing trend until the indoor environment temperature reaches the target temperature.
For example, the number of heating elements is 3, the target temperature is 26 ℃, and the outlet air temperature is set to 40 ℃. After the 3 heating elements are started to operate for 20 minutes, if the indoor environment temperature reaches 20 ℃ and the air outlet temperature reaches 45 ℃, the difference value delta T is obtainedCAt 5 deg.c, 1 heating element is turned off according to the current indoor environment temperature of 20 deg.c and the difference of 5 deg.c. If the indoor ambient temperature reaches 23 ℃ and the outlet air temperature reaches 48 ℃, the difference value delta T is obtainedCAnd at 8 ℃, 2 heating elements are closed according to the current indoor environment temperature of 23 ℃ and the difference value of 8 ℃.
According to the control method of the fan heater, after the heating component is started for the preset time period, when the indoor environment temperature and the air outlet temperature are increased to a certain temperature range, the heating quantity of the heating component is reduced by reducing the starting quantity of the heating components, so that energy and electricity are saved, the temperature increase of the air outlet can be slowed down, or the temperature of the air outlet can be reduced, and the problem that the service life of the heating component is influenced by overhigh surface temperature is avoided; the air outlet can be prevented from being overhigh in temperature, the indoor environment temperature can be more smoothly raised, and the user experience is improved.
In the embodiment of the present invention, before the step of controlling to turn on the set number of heating elements in step S200, the method further includes the steps of:
s201, determining the set number according to the comparison result between the indoor ambient temperature and the set indoor ambient temperature, specifically:
if the indoor environment temperature is less than the first set indoor environment temperature, the set number is n;
if the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature, the set number is n1；
If the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature, the set number is n2(ii) a Wherein n is2≤n1N is more than or equal to 2, and the number of the heating elements in the heating assembly is at least n.
For example, the number of the heating members is 3, the first setting room inside ring temperature is 15 ℃, the second setting room inside ring temperature is 20 ℃, and the target temperature is 26 ℃. If the indoor environment temperature is less than or equal to 15 ℃, the body feeling of the human body is relatively cold, and all heating elements are turned on to heat as soon as possible; if the indoor environment temperature is more than or equal to 15 ℃ and less than 20 ℃, starting 2 heating elements to ensure that the indoor environment temperature rises at a slow speed; if the indoor environment temperature is more than or equal to 20 ℃ and less than 26 ℃, the indoor environment temperature is higher, the body feeling of a human body is more comfortable, and only 1 heating element is started at the moment, so that the indoor environment temperature is slowly increased.
In the embodiment of the invention, after n heating elements are turned on and run for a first preset time period, the indoor environment temperature is increased along with the difference value delta TCThe increase of (2) reduces the number of the heating elements that are turned on, specifically including:
if the indoor environment temperature is less than the second set indoor environment temperature, and delta TCIf the difference is less than the predetermined difference, the number of the heating elements to be turned on is reduced to n1；
If the indoor environment temperature is less than the second set indoor environment temperature, and delta TCNot less than the preset difference value, the opening number of the heating element is reduced to n2；
If the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature, reducing the opening number of the heating elements to n2。
Specifically, n is 3, n1＝2，n2The example is given by 1. Under the condition that 3 heating elements are started when the indoor environment temperature is less than the first set indoor environment temperature, if the indoor environment temperature is still less than the first set indoor environment temperature after the fan heater operates for the first preset time periodAt the moment, if the air outlet temperature is lower than the set air outlet temperature, the opening number of the heating elements is kept to be 3; if Δ TCIf the difference value is less than the preset difference value, reducing the starting number of the heating elements to 2, namely closing 1 heating element; if Δ TCNot less than the preset difference, then reduce the opening quantity of heating member to 1, close 2 heating members promptly. Wherein, the set air outlet temperature can be set to 40 ℃, and the preset difference value can be set to 5 ℃.
Under the condition that 3 heating elements are started when the indoor environment temperature is less than the first set indoor environment temperature, if the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature after the fan heater operates for the first preset time period, at the moment, if the air outlet temperature is less than the set air outlet temperature or delta TCIf the difference value is less than the preset difference value, reducing the starting number of the heating elements to 2, namely closing 1 heating element; if Δ TCNot less than the preset difference, then reduce the opening quantity of heating member to 1, close 2 heating members promptly.
Under the condition that 3 heating elements are opened when the indoor environment temperature is less than the first set indoor environment temperature, if after the fan heater operates for the first preset time period, the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature, and at the moment, 2 heating elements are closed no matter the magnitude relation between the current air-out temperature and the set air-out temperature.
And under the condition that 3 heating elements are started when the indoor environment temperature is less than the first set indoor environment temperature, if the indoor environment temperature is more than or equal to the target temperature after the fan heater operates for the first preset time period, all the heating elements are closed.
In the embodiment of the invention, n is turned on1After the heating element operates for a first preset time period, the indoor ambient temperature is increased by the difference value delta TCThe increase of (2) reduces the number of the heating elements that are turned on, specifically including:
if the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature, and delta TCNot less than the preset difference value, the opening number of the heating element is reduced to n2；
If the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature, reducing the opening number of the heating elements to n2。
In particular toWhere n is 3, n1＝2，n2The example is 1. Under the condition that 2 heating elements are started when the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature, if the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature after the fan heater operates for the first preset time period, at the moment, if the air outlet temperature is less than the set air outlet temperature or delta TCIf the difference value is less than the preset difference value, the state of opening 2 heating elements is kept; if Δ TCBe greater than or equal to preset difference, then reduce the opening quantity of heating member to 1, close 1 heating member promptly.
Under the condition that 2 heating elements are opened when the first set indoor environment temperature is less than or equal to the indoor environment temperature and less than the second set indoor environment temperature, if the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature after the fan heater operates for the first preset time period, at the moment, no matter the size relation between the current air-out temperature and the set air-out temperature, the number of the heating elements which are opened is reduced to 1, and 1 heating element is closed.
And under the condition that 2 heating elements are started when the first set indoor environment temperature is less than or equal to the second set indoor environment temperature, if the indoor environment temperature is more than or equal to the target temperature after the fan heater operates for a first preset time period, all the heating elements are closed.
In the embodiment of the invention, n is turned on2And after the heating element operates for a first preset time period, reducing the opening number of the heating element according to the indoor environment temperature.
Specifically, n is 3, n2The example is 1. And under the condition that 1 heating element is started when the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature, if the second set indoor environment temperature is less than or equal to the indoor environment temperature and less than the target temperature after the fan heater operates for the first preset time period, keeping the starting number of the heating elements to be 1 no matter the size relation between the current air outlet temperature and the set air outlet temperature. And if the indoor environment temperature is not lower than the target temperature after the fan heater operates for the first preset time period, all the heating elements are closed.
In the warm air blower control method provided by the embodiment of the invention, the higher the indoor environment temperature is, the delta T isCThe larger the heating element, the smaller the number of heating elements controlled to be turned onSo as to reduce the heating quantity of the heating element to different degrees. The air supply experience at the air outlet is prevented from being influenced by overhigh temperature of the air outlet, so that the air outlet temperature at the air outlet is limited below a certain temperature; meanwhile, the problem that the service life of the heating element is influenced due to overhigh surface temperature of the heating element in a high room temperature environment is avoided. In addition, in the whole process of indoor environment temperature rise, the temperature rise rate is gradually reduced, so that the indoor environment temperature rises at a more moderate rate under the condition of higher indoor environment temperature, and the user experience is improved. In addition, the control method of the fan heater can reduce the energy consumption of the fan heater in the heating process.
In this embodiment of the present invention, before the indoor ambient temperature is increased to the target temperature in step S400, the method further includes:
and after the second preset time period for reducing the number of the heating elements to be started, if the indoor environment temperature is reduced, restarting one or more heating elements.
Specifically, after the number of the heating elements is reduced and the second preset time period is operated, the indoor environment temperature is in a descending trend, and one or more heating elements are restarted to avoid the indoor environment temperature from rising again and ensure that the indoor environment temperature is in an ascending trend. The number of the heating members to be restarted may be determined according to a reduction range of the indoor ambient temperature after the second preset time period. For example, after the number of the heating elements to be turned on is reduced and the operation is performed for 10 minutes, if the indoor ambient temperature is reduced by 3 °, one heating element is restarted; and if the indoor environment temperature is reduced by 8 degrees, restarting the two heating elements.
After restarting a heating element, if the indoor environment temperature obtained at the current moment is still lower than the indoor environment temperature before 2 minutes, continuing restarting the heating element until the current indoor environment temperature is higher than the indoor environment temperature before 5 minutes.
In the embodiment of the invention, all the heating elements are closed after the indoor environment temperature rises to the target temperature. When all the heating elements are in a closed state, the heating elements with the set number are opened according to indoor environment temperature control, and the heating of the fan heater is restarted. The set number is determined according to a comparison result between the indoor ambient temperature and the set indoor ambient temperature, which is specifically referred to in step S201 and is not described herein again.

and acquiring heating mode information selected by a user, wherein the heating mode comprises a quick heating mode and a standard mode. The two heating modes are preset in the heater control system, and heating mode information is obtained according to a control instruction of a user. The number of the heating elements to be turned on is determined according to the heating mode information.
Specifically, if the heating mode is a quick heating mode, the set number is determined to be the number of all the heating members, so that the heating assembly can quickly heat with the highest heating amount in a first preset time period.
If the heating mode is a standard mode, the indoor environment temperature and the difference value delta T are usedCAnd determining the set quantity to enable the heating assembly to slowly heat with a lower heating quantity in a first preset time period.
