[0002] The bathroom heater is a common device installed in the bathroom. When the warm air mode is turned on, the bathroom heater can inhale the air in the bathroom, heat the inhaled air and then blow it out into the bathroom to prevent the indoor temperature of the bathroom from being too low. In order to relieve the stuffiness in the bathroom and to improve the ventilation efficiency of the bathroom, some bathroom heaters on the market also have a fresh air function. That is, the bathroom heater can also introduce outdoor air into the bathroom.

[0003] In order to make the bathroom reach a comfortable temperature, some traditional bathroom heaters without fresh air function will control their operation according to the indoor temperature.

[0041] To facilitate the introduction of the fresh air bathroom heater control method of the present invention (hereinafter referred to as the control method), one of the fresh air bathroom heaters 100 that can be controlled by the control method of the present invention is first introduced below.

[0042] Reference Figure 2 and Figure 3 The fresh air bathroom heater 100 includes a housing 101, a heater 204, a fresh air valve 109, a return air valve 210, an air inlet fan 305, an indoor sensor 203, an outdoor sensor 211 and a controller (the controller is not shown in the drawings).

[0043] The housing 101 is provided with a fresh air inlet 102, a return air inlet 201 and an air outlet 104. The return air inlet 201 and the air outlet 104 are arranged in the bathroom, for example, the return air inlet 201 and the air outlet 104 are exposed from the ceiling of the bathroom. The air outlet 104 is arranged in the outdoor environment, or the air outlet 104 is located inside the building but communicated with the outdoor environment through a pipeline.

[0044] Reference Figure 3 The fresh air valve 109 is installed at the fresh air inlet 102, and the fresh air valve 109 can open or close the fresh air inlet 102. When the fresh air inlet 102 is opened, the fresh air (outdoor air) can enter the interior of the fresh air bathroom heater 100 through the fresh air inlet 102. The return air valve 210 is installed at the return air inlet 201, and the return air valve 210 can open or close the return air inlet 201. When the return air inlet 201 is opened, the indoor air can enter the interior of the fresh air bathroom heater 100 through the return air inlet 201.

[0045] Reference Figure 7 In one embodiment, the fresh air valve 109 includes a first motor 108 and a first baffle 107, and the first motor 108 is connected to the first baffle 107 and is used to drive the first baffle 107 to rotate. Figure 7 As shown, when the first baffle 107 rotates to an angle that does not completely block the fresh air inlet 102, the fresh air inlet 102 is in an open state, and outdoor air can enter the interior of the fresh air bathroom heater 100 through the fresh air inlet 102. Figure 7 If the first baffle 107 rotates to the point where both the upper and lower ends abut against the inner wall of the fresh air inlet 102, the first baffle 107 completely blocks the fresh air inlet 102, and the fresh air inlet 102 is in a closed state, and outdoor air cannot enter the interior of the fresh air bathroom heater 100 through the fresh air inlet 102. It should be noted that the fresh air bathroom heater 100 also includes a filter screen 302, which is disposed downstream of the fresh air valve 109. The filter screen 302 has mesh holes and will not completely block air from entering the air inlet duct 301.

[0046] Similarly, refer to Fig.10 In one embodiment, the return air valve 210 includes a second motor 202 and a second baffle 402, and the second motor 202 is connected to the second baffle 402 and is used to drive the second baffle 402 to rotate. Fig.10 As shown, when the second baffle 402 completely blocks the return air inlet 201, the return air inlet 201 is in a closed state, and the indoor air cannot enter the interior of the fresh air bathroom heater 100 through the return air inlet 201. Fig.11 As shown, when the second baffle 402 and the return air inlet 201 are offset by a certain angle, the return air inlet 201 is in an open state, and indoor air can enter the interior of the fresh air bathroom heater 100 through the return air inlet 201.

[0047] like Figure 3As shown, the indoor sensor 203 is installed at the return air inlet 201, and the indoor sensor 203 is set as a temperature and humidity sensor. The indoor sensor 203 is used to detect the indoor temperature and indoor humidity. The outdoor sensor 211 is installed at the fresh air inlet 102, and the outdoor sensor 211 is set as a temperature sensor. The outdoor sensor 211 is used to detect the outdoor temperature. The indoor sensor 203 and the outdoor sensor 211 are both connected to the controller for communication. The controller can receive the detection result of the indoor sensor 203 to obtain the indoor temperature and indoor humidity, and the controller can receive the detection result of the outdoor sensor 211 to obtain the outdoor temperature.

[0048] The air inlet fan 305 can drive the indoor air from the return air inlet 201 into the interior of the fresh air bathroom heater 100, and drive the outdoor air from the fresh air inlet 102 into the interior of the fresh air bathroom heater 100. In addition, the air inlet fan 305 can also drive the air to flow through the heater 204 and the air outlet 104 in sequence. To explain the air duct structure of the fresh air bathroom heater 100, the housing 101 is first introduced below. Figure 2 and Figure 3 In one embodiment, the housing 101 includes a body 207, a partition 209, a cover 208 and a panel 401. The panel 401 is provided with a first grille 105, the first grille 105 shields the return air inlet 201, and the air outlet 104 can be provided on the panel 401. Figure 6 and Figure 7 The partition plate 209 is disposed inside the body 207 and defines a first installation cavity 406 together with the body 207. The air intake fan 305 is installed in the first installation cavity 406. Figure 6 and Figure 7 The housing 208 is connected to the partition 209 and defines an air inlet duct 301. One end of the air inlet duct 301 is connected to the fresh air inlet 102. The return air inlet 201 is provided on the housing 208. Figure 7 and Figure 8 The partition plate 209 is provided with an air port 403, which is connected to the air inlet duct 301. The air port 403 is provided at the inlet end of the air inlet fan 305. The air inlet fan 305 is a centrifugal fan. Under the drive of the air inlet fan 305, indoor air or outdoor air can enter the air inlet duct 301, then enter the first installation cavity 406 from the air port 403, and then flow to the Fig. 9 The heater 204 can be installed in the A area (i.e., the right end of the first installation cavity 406). The heater 204 can be installed in the A area, and the outlet end of the heater 204 faces the air outlet 104. In this way, the air inlet fan 305 can drive the outdoor air or the indoor air to flow to the heater 204 and the air outlet 104 in sequence. The heater 204 can heat the air, so that the fresh air bathroom heater 100 blows out higher temperature air.

[0049] The heater 204, the fresh air valve 109, the return air valve 210, and the air inlet fan 305 are also connected to the controller for communication, and the controller can control the operation of the heater 204, the fresh air valve 109, the return air valve 210, and the air inlet fan 305. The fresh air bathroom heater 100 has a fresh air mode and a warm air mode. Figure 5 When the fresh air bathroom heater 100 operates in the fresh air mode, the fresh air inlet 102 is opened, the return air inlet 201 is closed, the heater 204 is turned on, and the air inlet fan 305 drives the outdoor air to flow through the fresh air inlet 102, the heater 204 and the air outlet 104 in sequence. Figure 4 When the fresh air bathroom heater 100 operates in warm air mode, the fresh air inlet 102 is closed, the return air inlet 201 is opened, the heater 204 is turned on, and the air inlet fan 305 drives the indoor air to flow through the return air inlet 201, the heater 204 and the air outlet 104 in sequence.

[0050] The operation of the fresh air bathroom heater 100 can be controlled by the control method of the present invention, and the control method provided by the present invention can be executed by the controller of the fresh air bathroom heater 100. Figure 1 The control method includes executing the main steps, and the main steps include:

[0051] S10: Obtain indoor temperature, indoor humidity and outdoor temperature;

[0052] S20: According to the indoor temperature, indoor humidity and outdoor temperature, the fresh air bathroom heater 100 is controlled to operate in the fresh air mode or the warm air mode, and the power of the heater 204 is adjusted.

[0053] Through this control method, the fresh air mode or warm air mode can be automatically selected in real time according to the indoor and outdoor environments, and the heating power of the heater 204 can be automatically adjusted, thereby improving the comfort of the wind blown by the fresh air bathroom heater 100, thereby making the bathroom reach a comfortable temperature.

[0054] The control method is introduced and supplemented in detail below. For the convenience of description, the indoor temperature is recorded as T N , let the indoor humidity be α and the outdoor temperature be T W .

[0055] In one embodiment, step S20 includes: when T N ≤18℃ and 0℃<T W ≤18°C, the fresh air bathroom heater 100 is operated in the fresh air mode, and the power of the heater 204 is adjusted to the first power; when T N ≤18℃ and 18℃<T W When the temperature is ≤26°C, the fresh air bathroom heater 100 is operated in the fresh air mode, and the power of the heater 204 is adjusted to a second power, wherein the first power is greater than the second power.

[0056] That is, in T N ≤18℃ and 0℃<T W ≤26℃, the fresh air bathroom heater 100 can operate in fresh air mode, providing heated fresh air for the bathroom to improve the comfort of the bathroom environment. W When the temperature is ≤26℃, the fresh air still needs to be heated, but due to the high temperature of the fresh air, the heater 204 can be operated at a lower power to prevent the outlet temperature of the fresh air bathroom heater 100 from being too high. The specific values ​​of the first power and the second power are not specifically limited here. The description of the first power and the second power is mainly to express: 0℃<T W When the temperature is less than 18℃, the heater 204 operates at a higher power. W When the temperature is ≤26°C, the heater 204 operates at a lower power.

[0057] In one embodiment, step S20 further includes: when T N ≤18℃ and T W When the temperature is ≤0℃, the fresh air bathroom heater 100 is operated in the warm air mode, and the power of the heater 204 is adjusted to the first power.

[0058] The purpose of this setting is to prevent cold outdoor air from being introduced into the room. W When the temperature is ≤0℃, if outdoor air is introduced into the fresh air bathroom heater 100, there is a risk of frost inside the fresh air bathroom heater 100. W ≤0℃, the outdoor air temperature is low, heating it to a temperature that can provide heating for users requires a higher heating power, which will increase the energy consumption of the fresh air bathroom heater 100. The indoor air temperature will be higher than the outdoor air temperature, so at T N ≤18℃ and T W When the temperature is ≤0℃, the warm air mode can be turned on and the heater 204 can be operated at a higher power, so that the fresh air bathroom heater 100 can quickly provide warm air outlet and reduce the energy consumption of the fresh air bathroom heater 100 and the risk of damage to the fresh air bathroom heater 100.

[0059] In one embodiment, step S20 further includes: when 18°C ​​< T N <26℃ and T W ≤18℃, the fresh air bathroom heater 100 is controlled to operate in the fresh air mode, and the power of the heater 204 is adjusted to the first power; when 18℃<T N <26℃ and 18℃<T W When the temperature is ≤26℃, the fresh air bathroom heater 100 is controlled to operate in the fresh air mode, and the power of the heater 204 is adjusted to the second power, and the first power is greater than the second power. This setting can also enable the fresh air bathroom heater 100 to provide warm fresh air for the bathroom, improve the comfort of the bathroom environment, and reduce energy consumption.

[0060] In one embodiment, step S20 further includes: when 18°C ​​< T N <26℃ and T W >26℃, control the fresh air bathroom heater 100 to operate in fresh air mode and turn off the heater 204. This setting is mainly considered when T W When the temperature is greater than 26°C, the temperature of the outdoor air is relatively high, and the heater 204 may be turned off to reduce energy consumption.

[0061] In one embodiment, step S20 further includes: when T N ≥26℃, α≥98%, and T W When the temperature is ≤0℃, the fresh air bathroom heater 100 is controlled to operate in the ventilation mode for a first preset time, and then the fresh air bathroom heater 100 is controlled to operate in the warm air mode.

[0062] Here is an explanation of the ventilation modes. Figure 8 and Fig. 9 In one embodiment, the fresh air bathroom heater 100 further includes an exhaust fan 205, and the housing 101 is further provided with an exhaust inlet 206 and an exhaust outlet 103. The second grille 106 of the panel 401 can cover the exhaust inlet 206. The exhaust inlet 206 is arranged in the bathroom, for example, the exhaust inlet 206 and the return air inlet are arranged side by side, and both are exposed from the ceiling; the exhaust outlet 103 can be connected to the exhaust duct in the building. When the fresh air bathroom heater 100 is operated in the exhaust mode, driven by the exhaust fan 205, the indoor air can flow through the exhaust inlet 206 and the exhaust outlet 103 in sequence. Refer to Figure 6 In the exhaust mode, the fresh air bathroom heater 100 can exhaust part of the air in the bathroom to relieve the stuffiness in the bathroom. More specifically, the body 207 and the partition 209 also define a second installation cavity 407 together, the first installation cavity 406 and the second installation cavity 407 are separated from each other, the exhaust fan 205 is arranged in the second installation cavity 407, and the exhaust inlet 206 is arranged on the partition 209. The exhaust fan 205 is also configured as a centrifugal fan, and the indoor air enters the second installation cavity 407 after passing through the exhaust inlet 206, and then flows forward from the second installation cavity 407 to the exhaust inlet 206.

[0063] When T N ≥26℃, α≥98%, the bathroom environment is in a humid and hot state. At this time, the exhaust mode can be turned on to exhaust some of the hot and humid air in the bathroom. The first preset time is pre-set in the program of the fresh air bathroom heater 100. In one embodiment, the first preset time can be 1 minute; of course, the first preset time can also be adjusted appropriately, for example, adjusted to 30 seconds, 2 minutes, etc., which are not listed here. When the exhaust mode ends, due to T W ≤0℃, it is not suitable to introduce cold air from outside, so choose to run in warm air mode.

[0064] Of course, there are other ways to relieve the stuffiness in the bathroom. For example, in one embodiment, step S20 also includes: when T N ≥26℃, α≥98%, and 0℃<T W ≤18℃, the fresh air bathroom heater 100 is controlled to operate in the fresh air mode, and the power of the heater 204 is adjusted to the second power. W When the temperature is ≤18°C, fresh air can be introduced into the bathroom to relieve the stuffiness in the bathroom. Moreover, since the fresh air needs to relieve the stuffiness in the bathroom, the heater 204 operates at a lower power to avoid heating the fresh air to an excessively high temperature.

[0065] In one embodiment, step S20 further includes: when T N ≥26℃, α≥98%, and 18℃<T W ≤26℃, control the fresh air bathroom heater 100 to operate in fresh air mode, and turn off the heater 204. This setting also relieves the stuffy state of the bathroom by introducing fresh air, because at this time 18℃<T W ≤26℃, the outdoor air temperature is relatively high and can be directly introduced into the bathroom without heating.

[0066] The control logic of the above step S20 is shown in the following table: Wherein, "high gear" means that the heater 204 operates at the first power, and "low gear" means that the heater 204 operates at the second power.

[0067]

[0068] In one embodiment, the control method further includes: before executing the main step, executing a preparation step, the preparation step includes:

[0069] S01: Turn on the heating mode and keep it for a second preset time, and turn on the indoor sensor 203;

[0070] S02: Turn off the warm air mode, then turn on the fresh air mode and keep it for a third preset time, and turn on the outdoor sensor 211.

[0071] When the fresh air bathroom heater 100 is in operation, the temperature and humidity values ​​measured by the indoor sensor 203 are "regarded" as the indoor temperature and indoor humidity, and the temperature value measured by the outdoor sensor 211 is "regarded" as the outdoor temperature. However, based on the installation position of the sensor, when the air is not flowing, there is a certain temperature difference between the air in the outdoor environment and the air near the outdoor sensor 211, and there is also a certain temperature difference between the air temperature at the user's position in the bathroom and the air near the indoor sensor 203. The preparation step is mainly performed to make the air flow first, so as to reduce the error between the parameters measured by the indoor sensor 203 and the outdoor sensor 211 and the true value. The second preset time and the third preset time are also pre-set in the program of the controller. In order to enable the fresh air bathroom heater 100 to adjust the temperature and humidity in the bathroom as quickly as possible, in one embodiment, the second preset time and the third preset time can both be set to 10 seconds.

[0072] The present invention also provides a computer-readable storage medium, which stores a computer program, and when the computer program is executed by a processor, the fresh air bathroom heater control method described in any of the above embodiments is implemented. The controller of the fresh air bathroom heater 100 may be integrated with a processor for executing the computer program.

[0073] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
