Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a zero-wind-feel air conditioner and its control method. Background Technology

[0002] As people's living standards improve, air conditioners have become one of the essential home appliances. As a widely used household appliance, air conditioners have become an integral part of people's lives.

[0003] Existing zero-wind-feel air conditioners have ventilation holes set on the air guide plate. When the air is ventilated, the ventilation holes can disperse the airflow to reduce the wind speed and disrupt the direction of airflow, thus avoiding direct airflow onto the human body.

[0004] However, the above solution has the following problems: (1) Only the air guide plate can produce air in the zero wind mode. The air outlet area on the air guide plate is small and condensation is very easy to occur; (2) When the air conditioner is cooling, the temperature of the air outlet is low and the indoor temperature is much different, which causes water vapor in the air to condense and accumulate, making it easy for condensation to form on the surface of the air guide plate. A large amount of condensation accumulated on the air guide plate will hinder the air outlet, reduce the air volume, and the blown air will carry water vapor, resulting in poor user comfort. Summary of the Invention

[0005] In view of this, the present invention aims to propose a zero-wind-feel air conditioner and its control method. This addresses the problems in existing technologies where only the air guide plate emits air in zero-wind-feel mode, resulting in a small air outlet area on the air guide plate that easily leads to condensation. Furthermore, when the air conditioner is cooling, the temperature at the air outlet is low, while the indoor temperature differs significantly, causing water vapor in the air to condense and accumulate. This makes it easy for condensation to form on the surface of the air guide plate. A large amount of condensation accumulating on the air guide plate obstructs airflow, reducing the air volume, and the blown air contains moisture, resulting in poor user comfort.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A zero-wind-feel air conditioner includes an air conditioning body, which includes an air outlet and an electric heater. An air guide plate is disposed on the outside of the air outlet, and the electric heater is connected to the air guide plate. The air guide plate has a first microporous structure, and the electric heater has a second microporous structure. The pore size of the first microporous structure is larger than that of the second microporous structure. The electric heater includes a flexible body and a connecting part. The second microporous structure is located on the flexible body, and the connecting part is located at both ends of the flexible body. The electric heater is connected to a power supply unit through a connecting wire.

[0008] This invention improves the zero-wind-feel effect by setting an electric heater with a microporous structure on the air guide plate, so that the airflow is diffused secondary after passing through the air guide plate and the electric heater. In addition, the electric heater applies a certain voltage to appropriately increase the outlet air temperature, which can effectively prevent condensation and avoid large fluctuations in indoor temperature, thereby improving user comfort.

[0009] Furthermore, the air guide plate is a plate structure, the electric heater is disposed on the inner or outer side of the air guide plate, the air guide plate is provided with a groove, the connecting part is disposed in the groove, and the groove allows the flexible body to be in close contact with the air guide plate.

[0010] This setting allows the heat generated by the electric heater to quickly reach the air guide plate, appropriately increasing the outlet temperature of the air guide plate and preventing condensation.

[0011] Furthermore, the flexible body covers the air guide plate.

[0012] This design increases the contact area between the flexible body and the air guide plate, allowing the air guide plate to heat up more quickly when the flexible body is heated. This also appropriately increases the outlet temperature of the air guide plate, preventing condensation and improving user comfort.

[0013] Furthermore, the air guide plate has a cavity structure, and the electric heater is disposed at one end close to the cavity structure, and the electric heater slides within the cavity structure.

[0014] This setting can provide multiple zero-wind-feel airflow modes for user convenience and can prevent condensation.

[0015] Furthermore, the electric heater is mounted on a reel, and the reel is mounted on the air conditioner body.

[0016] This feature allows the electric heater to be rolled up when not in use, thus extending its lifespan.

[0017] Furthermore, the air conditioner body includes a rotating shaft, the two ends of which are movably connected to the air conditioner body.

[0018] A method for controlling a zero-wind-feel air conditioner, comprising the aforementioned zero-wind-feel air conditioner, includes the following steps:

[0019] S1. In air conditioning cooling mode, turn on zero-wind mode;

[0020] S2, Real-time monitoring of indoor temperature T 内 Relative humidity (RH) and outlet air temperature (T) of the air guide plate 出 ;

[0021] S3. Determine the dew point temperature T based on the indoor temperature and relative humidity.LU ;

[0022] S4. Determine the dew point temperature T LU With T 出 The critical temperature difference L between them 临 To determine whether the electric heater is activated in a zero-wind-feel state.

[0023] This setting not only improves human comfort in a zero-wind state, but also prevents condensation from forming on the air deflector.

[0024] Furthermore, step S4 also includes the following steps:

[0025] S41, when L 临 > First preset value: Zero-wind air conditioner blows air normally, electric heater is in the off state;

[0026] S42, When the second preset value ≤ L 临 If the value is less than or equal to the first preset value, start the electric heater.

[0027] S43, when L 临 <Second preset value: Do not start the electric heater, increase the fan speed.

[0028] This setup aims to ensure the safety of the electric heater while effectively preventing condensation on the air guide plate and improving comfort for people in a zero-wind-feel state.

[0029] Further, step S42 includes the following steps:

[0030] S421. Based on the voltage applied to the electric heater, obtain the heating temperature T on the electric heater. 发 ;

[0031] S422, when T 发 ≥T 出 When +ΔT, reduce the voltage applied by the electric heater and return to step S421;

[0032] S423, when T 出 ≤T 发 <T 出 At +ΔT, the electric heater operates at T. 发 Run for the first preset time t 设 Then, return to step S2;

[0033] S424, when T 发 <T 出 Increase the voltage applied by the electric heater and return to step S421.

[0034] This setting ensures normal airflow even in zero-wind conditions, while preventing excessive fluctuations in indoor temperature due to heat generation, and ultimately avoiding condensation.

[0035] Furthermore, it also includes a control device, comprising the following:

[0036] The first detection unit is used to detect the current indoor temperature and humidity.

[0037] The calculation unit is used to calculate the current critical temperature difference in the room based on the indoor temperature and indoor humidity.

[0038] The second detection unit is used to obtain the air outlet temperature of the air guide plate;

[0039] The third detection unit is used to obtain the heating temperature of the electric heater based on the voltage applied by the electric heater;

[0040] A control unit is used to control the electric heater according to the critical temperature difference;

[0041] The control unit is also used to control the voltage applied to the electric heater based on the heating temperature of the electric heater and the air outlet temperature of the air guide plate.

[0042] The control device in this setup enables the zero-wind-feel mode of the zero-wind-feel air conditioner and prevents condensation from forming on the air deflector.

[0043] Compared with existing technologies, the zero-wind-feel air conditioner and its control method described in this invention have the following advantages:

[0044] 1) This invention improves the zero-wind-feel effect by setting an electric heater with a microporous structure on the air guide plate, so that the airflow is diffused secondary through the air guide plate and the electric heater. In addition, the electric heater applies a certain voltage to appropriately increase the outlet air temperature, which can effectively prevent the generation of condensation and avoid large fluctuations in indoor temperature, thereby improving user comfort.

[0045] 2) The control method of the present invention can ensure the safety of the electric heater, and at the same time effectively avoid the indoor temperature from fluctuating too much due to the heating temperature, and finally avoid condensation on the air guide plate, thereby improving the comfort of the human body in the zero-wind state.

Detailed Implementation

[0057] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] In existing technologies, to avoid condensation during zero-wind operation, the compressor frequency is usually changed. However, changing the compressor frequency increases the noise of the air conditioning system, resulting in a poor user experience. Furthermore, changing the compressor frequency causes large fluctuations in indoor temperature, causing discomfort to the human body. Therefore, this application is hereby filed.

[0059] Example 1

[0060] like Figure 1-4 As shown, the present invention proposes a zero-wind-feel air conditioner, including an air conditioner body 1, the air conditioner body 1 including an air outlet 11, an air guide plate 12 disposed on the outside of the air outlet 11, the air guide plate having a first microporous structure 122, an electric heater 2 disposed on the air guide plate 12, the electric heater 2 having a second microporous structure 211, and the electric heater 2 being detachably connected to the air guide plate 12.

[0061] The present invention provides an electric heater 2 on the air guide plate 12, which can increase the temperature of the air guide plate, prevent condensation from forming on the air guide plate, and reduce human comfort.

[0062] Specifically, the two ends of the electric heater 2 are connected to the power supply unit 4 via connecting wires 3. As an embodiment of this application, the electric heater 2 is supplied with a certain voltage by the power supply unit, which causes the surface of the electric heater to heat up, thereby increasing the temperature of the air guide plate surface, thus increasing the temperature of the air outlet and preventing condensation from occurring on the air guide plate.

[0063] Specifically, one end of the electric heater is connected to the positive terminal of the power supply unit 4, and the other end of the electric heater is connected to the negative terminal of the power supply unit 4.

[0064] Specifically, the electric heater 2 is disposed on the inner or outer side of the air guide plate 12.

[0065] Specifically, the electric heater is detachably installed on the inner or outer side of the air guide plate, wherein the power supply unit is reasonably arranged according to the installation position of the electric heater, as long as it can provide a continuous DC voltage when the electric heater needs to heat.

[0066] Specifically, in this application, the electric heater 2 is a flexible conductive component, which includes a flexible body 21 and a connecting part 22. The connecting part 22 is located at both ends of the flexible body 21. The air guide plate 12 is provided with a groove 123, and the connecting part 22 is disposed in the groove 123, so that the flexible body 21 is in close contact with the air guide plate 12.

[0067] The flexible substrate in this application possesses a certain degree of conductivity, exhibits uniform conductivity, and its size at least covers the air guide plate. Under a certain applied voltage, it can generate a sustained heating temperature on its surface, and this heating temperature is related to the size, resistance, voltage, and other related properties of the flexible substrate. The flexible substrate can be an existing uniformly conductive fabric, a porous polymer membrane, a metal mesh, etc.

[0068] Preferably, the flexible main body is a conductive fabric, and the conductive fabric has a water-repellent function to prevent the heating performance of the conductive fabric from being affected during electric heating. When not heating, the microporous structure of the air guide plate first disperses the airflow to a certain extent, and the conductive fabric disperses the airflow a second time, resulting in a better user experience when the zero-wind mode is turned on.

[0069] The connecting part in this application is a metal conductive plate, and the connecting part is located on the inner surface and outer surface of the flexible body. The connection between the connecting part and the flexible body can also be made by other connecting parts, as long as the connection between the connecting part and the flexible body is firm.

[0070] Specifically, the air conditioner body includes a rotating shaft 13, the two ends of which are mounted on the air conditioner body 1, and the rotating shaft 13 can realize the rotation of the air guide plate.

[0071] This application discloses a zero-wind-feel air conditioner, which also includes a control device, as follows:

[0072] The first detection unit is used to detect the current indoor temperature and humidity.

[0073] The calculation unit is used to calculate the current critical temperature difference in the room based on the indoor temperature and indoor humidity.

[0074] The second detection unit is used to obtain the air outlet temperature of the air guide plate;

[0075] The third detection unit is used to obtain the heating temperature of the electric heater based on the voltage applied by the electric heater;

[0076] A control unit is used to control the electric heater according to the critical temperature difference;

[0077] The control unit is also used to control the voltage applied to the electric heater based on the heating temperature of the electric heater and the air outlet temperature of the air guide plate.

[0078] The proposed solution adjusts the heating temperature of the electric heater by real-time monitoring of parameters such as indoor temperature and humidity when the air conditioner is in zero-wind-feel cooling mode. This improves the cooling capacity of the air conditioner and enhances the user experience while ensuring that condensation does not occur in the zero-wind-feel mode.

[0079] Specifically, the first detection unit is a temperature and humidity sensor, which is installed on the indoor unit of the air conditioner; the second detection unit is a temperature sensor, which is installed on the air guide plate of the indoor unit of the air conditioner; and the third detection unit is an infrared thermal imager, which is installed on the indoor unit of the air conditioner, and the temperature probe of the infrared thermal imager is close to the flexible body.

[0080] This application proposes a control method for a zero-wind-feel air conditioner, employing the aforementioned zero-wind-feel air conditioner, comprising the following steps:

[0081] S1. In air conditioning cooling mode, turn on zero-wind mode;

[0082] In this application, when the zero-wind mode is activated, the air deflector blocks the air outlet.

[0083] S2, Real-time monitoring of indoor temperature T 内 Indoor humidity (RH) and air outlet temperature (T) of the air guide plate 出 ;

[0084] S3. Determine the dew point temperature T based on the indoor temperature and humidity. LU ;

[0085] S4. Determine the dew point temperature T LU With T 出 The critical temperature difference L between them 临 To determine whether the electric heater is started or not;

[0086] Among them, L 临 =T 出 -T LU ,

[0087] It should be noted that the dew point temperature T LU The definition is: in the current indoor environment (indoor temperature T) NH The lowest temperature at which condensation will occur under indoor humidity (RH) conditions. Theoretically, as long as T... 出 -T LU If the value is greater than 0, condensation will not occur.

[0088] S41, when L 临 > The first preset value indicates that there is no risk of condensation on the air guide plate, the zero-wind air conditioner blows air normally, and the electric heater is in the off state;

[0089] Preferably, the first preset value of the present invention is 3 to 6°C.

[0090] S42, When the second preset value < L 临 If the value is less than or equal to the first preset value, the electric heater will be activated. There is a risk of condensation forming on the air guide plate; in this case, the surface of the heat-conducting plate is heated by the electric heater.

[0091] Preferably, the second preset value of the present invention is 0 to 3°C.

[0092] S421. Based on the voltage applied to the electric heater, obtain the heating temperature T on the electric heater. 发 ;

[0093] S422, when T 发 ≥T 出 When +ΔT, reduce the voltage applied by the electric heater and return to step S421;

[0094] S423, when T 出 ≤T 发 <T 出 At +ΔT, the electric heater operates at T. 发 Run for the first preset time t 设 Then, return to step S2;

[0095] S424, when T 发 <T 出Increase the voltage applied by the electric heater and return to step S421.

[0096] In this application, ΔT refers to the temperature difference between the fluctuating air outlet temperature at the human comfort level, that is, the difference between the maximum and minimum set air outlet temperature.

[0097] S43, when L 临 ≤2 preset value. At this point, condensation has already formed on the air guide plate, and the electric heater does not start. This setting prevents the condensation from having an unsafe impact on the electric heater. At this time, the condensation on the air guide plate is evaporated quickly by increasing the fan speed of the air conditioner.

[0098] The heating temperature in this application has certain requirements, preferably between 15 and 37°C. If the heating temperature is too high, the cooling effect will not be achieved; if the heating temperature is too low, the decondensation effect will be insufficient, both resulting in a poor user experience. The voltage applied in this invention starts at a relatively low voltage.

[0099] The control method for the zero-wind-feel air conditioner in this application is applicable not only to the cooling mode of zero-wind-feel mode, but also to the cooling mode with a wind sensation. When there is a wind sensation, the air guide plate is rotated at a certain angle by rotating the rotating shaft so that it does not block the air outlet. By applying voltage to the electric heater, condensation is prevented from forming on the air guide plate.

[0103] Specifically, the electric heater 2 is detachably connected to the air guide plate 12.

[0104] Specifically, the two ends of the electric heater 2 are connected to the power supply unit 24 via connecting wires 23. As an embodiment of this application, the electric heater 2 is heated by applying a certain voltage through the power supply unit, thereby increasing the surface temperature of the electric heater and thus increasing the temperature of the air outlet and preventing condensation from forming on the air guide plate.

[0105] Specifically, one end of the electric heater is connected to the positive terminal of the power supply unit 24, and the other end of the electric heater is connected to the negative terminal of the power supply unit 24.

[0106] Specifically, the electric heater is detachably installed inside the air guide plate cavity structure, wherein the power supply unit 24 is reasonably arranged according to the installation position of the electric heater, as long as it can provide a continuous DC voltage when the electric heater needs to heat.

Under a certain applied voltage, it can generate a sustained heating temperature on its surface, and this heating temperature is related to the size, resistance, voltage, and related properties of the flexible conductive component. The flexible conductive component can be an existing uniformly conductive fabric, a porous polymer membrane, a metal mesh, etc.

[0109] Preferably, the flexible conductive element is a conductive fabric, and the conductive fabric has a water-repellent function to prevent the heating performance of the conductive fabric from being affected during electric heating. When not heating, the microporous structure of the air guide plate first disperses the airflow to a certain extent, and the conductive fabric disperses the airflow a second time, resulting in a better user experience when the zero-wind mode is turned on.

[0113] In a preferred embodiment of this application, the roller is mounted on the air conditioner body and in the cavity structure near the air guide plate. The roller is connected to a motor, enabling the motor to start and allowing the electric heater to roll on the roller. Slide rails are provided at both ends of the cavity. The moving device includes a slider, a drive device, and a controller. The drive device can drive the slider to move along the slide rails. A clamp is provided on the slider to easily clamp the end of the flexible body away from the roller. The controller can control the drive device and the clamp to clamp and release the flexible body. The drive device, controller, slider, and clamp are all existing structures, as long as they satisfy the requirement that the slider moves to drive the flexible conductive component. When the electric heater is not needed, the slider is disconnected from the electric heater; when the electric heater is needed, the slider moves the flexible conductive component.

[0114] This application proposes a control method for a zero-wind-sensor air conditioner, including a first zero-wind-sensor state and a second zero-wind-sensor state, which can be switched between each other. In the first zero-wind-sensor state, the air guide plate blocks the air outlet; in the second zero-wind-sensor state, the air guide plate blocks the air outlet, and the slider is moved so that the flexible conductive element is disposed within the cavity structure.

[0115] Specifically, the control method includes the following steps:
