Description

Air conditioner indoor unit and air conditioner indoor air outlet control method

Technical field

The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and an air outlet indoor air outlet control method.

Background technique

In the current summer air conditioner, in order to quickly reduce the indoor temperature, the temperature of the air outlet of the air conditioner is generally between 10 ° C and 15 ° C, and the temperature of the human body surface is generally between 30 ° C and 33 ° C. "Cold wind" direct blowing people will cause the human sweat gland to close, affecting normal metabolism and secretion. Staying in the air-conditioned room for a long time to blow "cold wind" will produce an "air conditioning disease."

《GB_T18049-2000 In the Medium Thermal Environment, the Measurement of PMV and PPD Index and the Regulations for Thermal Comfort Conditions, the eddy current intensity (DR) is defined as the degree of coldness of the body caused by air flow. The vortex airflow intensity is used to predict the percentage of people affected by the airflow. The vortex airflow intensity (DR) can be calculated as follows:

DR=(34-Ta)(V-0.05)0.62(0.37×V×Tu+3.14) where: DR---the vortex flow intensity, that is, the percentage that is unsatisfactory because of the vortex flow; Ta--- Local air temperature, °C; V --- Local average air flow rate, m / s; Tu - local turbulence intensity, which is defined as the ratio of the standard deviation of the local air flow rate to the local average air flow rate, %.

Generally, the DR value is within 20, and the ambient wind speed can be considered to be comfortable. That is, 20% of people are affected by the airflow and feel a cold feeling in the body. The ambient air state is recognized as comfortable by 80% of people.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides an air conditioner indoor unit. Referring to FIG. 1, in an embodiment, the air conditioner indoor unit is provided with an air outlet 10, a first air diffusing plate 20, a second air diffusing plate 30, a controller, and a humidity detector; The first air diffusing plate 20 and the second air diffusing plate 30 are respectively provided with a plurality of ventilation holes, and the first air diffusing plate 20 and the second air diffusing plate 30 cooperate with each other to block or open the air outlet 10 The humidity detector is for detecting ambient humidity;

In the cooling operation state of the air conditioner indoor unit, after entering the preset operation mode, the controller controls the first air diffusing plate 20 and the second air diffusing plate 30 to be at different rotational positions to form the air outlet 10 Blocking, changing the gap of the air outlet 10 for air outlet;

The controller determines whether to control the rotation of the first air diffusing plate 20 and the second air diffusing plate 30 according to the ambient humidity detected by the humidity detector, so that the air outlet is used for increasing the gap of the air outlet.

In this embodiment, the structures of the first air diffusing plate 20 and the second air diffusing plate 30 may be disposed according to actual needs. Preferably, the first air diffusing plate 20 and the second air diffusing plate 30 are elongated. Plate structure. Specifically, the air conditioner indoor unit further includes a chassis 40 and a face frame 50, wherein an indoor fan, an air inlet duct, and an air outlet duct are disposed in the chassis 40, wherein the face frame 50 is opened at an exit of the air outlet duct The above air outlet 10. The first louver 20 is rotatably mounted on the chassis 40, and the second louver 30 is rotatably mounted on the face frame 50, wherein the first louver 20 is located above the second louver 30. The rotation of the first louver 20 and the second louver 30 is controlled by a motor to open and block the vent 10.

Specifically, the vent hole includes a first vent hole disposed on the first louver 20 and a second vent hole disposed on the second louver 30. The venting hole is configured to allow the wind to enter the room through the vent hole when the first air diffusing plate 20 and/or the second air diffusing plate 30 block the air outlet 10, so as to reduce the air volume and the wind speed. It can be understood that the shape of the vent hole can be set according to actual needs, for example, the first ventilating plate 20 is provided with the first ventilation when the first louver 20 and the second louver 30 block the vent. The direction in which the hole extends from the inner side surface to the outer side surface of the first air diffusing plate 20 is inclined upward by a predetermined angle in the thickness direction of the first air diffusing plate 20; the second air venting hole provided in the second air diffusing plate 30 is the first The direction in which the inner side surface to the outer side surface of the diffuser panel 20 extends coincides with the thickness direction of the second diffuser panel 30.

It should be noted that, in this embodiment, preferably, the opening of the air outlet by the first air diffusing plate 20 and the second air diffusing plate 30 means that the normal air outlet of the air outlet 10 is not blocked; the first air diffusing plate 20 and The second louver 30 blocking the air outlet means that the first louver 20 and the second louver 30 block the wind blown from the air outlet duct, so that the first louver 20 and the second louver 30 are blown. The wind on the inner side enters the room through the vent hole, and is performed indoors through a gap between the first louver 20 and the second louver 30 (the gap of the air outlet 10 for air).

The types of the preset operation modes may be defined according to actual needs. In the following embodiments, the preset operation mode is the windless mode as an example, and the detailed description is made. The windless mode means that the air conditioner operates in a cooling operation state, and the direction of the air outlet of the air outlet is controlled to change, so that the indoor wind speed is lowered. The indoor wind speed is the measured wind speed at a distance of 3 m from the horizontal distance of the air conditioner. In the windless mode, the wind speed of the air outlet is lowered by blocking the air outlet, and the indoor wind speed is lowered. Preferably, by blocking the air outlet, the indoor wind speed can be lower than 0.3 m/s, that is, the comfort state is achieved.

Specifically, the controller controls the first louver 20 and the second louver 30 to be at different rotational positions according to the indoor temperature detected by the temperature detector to form an occlusion of the air outlet 10. The effect of the occlusion of the different rotational positions is that the smaller the indoor temperature is, the control of the first louver and the second louver occlude the air outlet, so that the gap of the air outlet for the air outlet is smaller. Thereby the smaller the amount of air flow.

Specifically, after entering the windless mode, the controller controls the first air diffusing plate 20 and the second air diffusing plate 30 to cooperate to reduce the air volume of the air outlet 10 to different degrees. Make settings. For example, it is possible to control the amount of air blown from the air outlet 10 in accordance with the temperature and the ambient humidity. Specifically, when the indoor temperature and the ambient humidity are lower, the amount of wind that fits the first first air diffusing plate 20 and the second air diffusing plate 30 in the room is larger, and the amount of air discharged from the air outlet 10 is smaller. The smaller the amount of air blown from the air outlet 10, the smaller the air flow speed of the environment, thereby improving the comfort of the environment. If the ambient humidity is increased after the air volume is reduced, it is easy to generate condensed water on the first and second diffuser plates. At this time, it is necessary to judge whether it is necessary to return to the state before the air volume adjustment according to the environmental humidity, so as to improve The amount of air discharged from the air outlet 10 avoids the generation of condensed water on the first and second diffuser plates.

In the embodiment of the present invention, after reducing the air volume of the air outlet 10, it is determined in real time whether the air volume of the air outlet 10 needs to be increased according to the environmental humidity, and the state of the first air diffusing plate 20 and the second air diffusing plate 30 is changed to improve the state. The air outlet amount of the air outlet 10 effectively prevents hot air from collecting on the outer side surface of the air diffusing plate, thereby effectively preventing the occurrence of condensed water.

It can be understood that, in this embodiment, the air conditioner indoor unit may include an air deflector or may not include a wind deflector, and the air deflector is used to block or open the air outlet 10, and the operating state of the air deflector may be Actual settings are required, and are not further defined herein.

Further, the controller controls the first air diffuser 20 and the second air diffuser 30 to reduce the airflow of the air outlet 10, including:

The controller controls the first air diffuser 20 and the second air diffuser 30 to rotate to a first preset position to open the air outlet 10; when the first preset condition is met, the controller controls the first The air diffuser 20 is rotated to a second preset position to partially block the air outlet 10; when the second preset condition is met, the controller controls the first air diffuser 20 and the second air diffuser 30 to rotate to In the third preset position, the first louver 20 and the second louver 30 cooperate with each other to block the air outlet 10.

The parameters determined by the first preset condition and the second preset condition may be set according to actual needs, for example, when the indoor air temperature and the ambient humidity are used to reduce the air volume of the air outlet 10: after entering the windless mode Firstly, the first air diffusing plate 20 and the second air diffusing plate 30 are controlled to rotate to a first preset position (the state thereof is as shown in FIG. 1) to open the air outlet 10; when the indoor temperature is less than or equal to the first When the preset temperature is lower than the first preset humidity, the first air diffusing plate 20 is controlled to rotate to a second preset position (the state thereof is as shown in FIG. 2) to partially block the air outlet. 10: controlling the first louver 20 and the second louver 30 to rotate to the third when the indoor temperature is less than or equal to the second preset temperature and the ambient humidity is less than the second preset humidity a preset position (the state thereof is as shown in FIG. 3), the first air diffusing plate 20 and the second air diffusing plate 30 cooperate to block the air outlet 10; the first preset temperature is greater than the second preset Temperature; the first preset humidity is greater than the second preset humidity.

Specifically, as shown in FIG. 1, the controller first controls the first air diffusing plate 20 and the second air diffusing plate 30 to open the air outlet 10 so that the indoor air outlet is normally blown out from the air outlet 10. At this time, the cold air is directly blown downward from the air outlet 10. In FIG. 2, a portion of the air outlet 10 is blocked only by the first air diffusing plate 20, so that a part of the blown wind is blocked by the first air diffusing plate 20, and the other part enters the room through the unobstructed portion of the air outlet 10. The portion of the wind blown on the inner side of the first diffuser 30 is blocked, and partially enters the room through the vent hole, thereby reducing the amount of air blown from the air outlet 10 with respect to the state of FIG. In FIG. 3, the air outlet 10 is shielded by the first air diffusing plate 20 and the second air diffusing plate 30, so that the blown air passes only through the air vents provided on the first air diffusing plate 20 and the second air diffusing plate 30. Entering the room; relative to FIG. 2, the amount of air discharged from the air outlet 10 is further reduced.

In this embodiment, the specific location points of the second preset location and the third preset location may be set according to actual needs. Preferably, in this embodiment, when the indoor temperature is between the first preset temperature and the second preset temperature, and the ambient humidity is less than the first preset humidity, only the first air diffusing plate 20 is controlled. The air volume reduction control is performed when the indoor temperature is less than the second preset temperature and the ambient humidity is less than the second preset humidity, and the air volume reduction control is performed by the first air diffusing plate 20 and the second air diffusing plate 30 to maximize the air volume Reduce the amount of air. Specifically, when the first air diffusing plate 20 and the second air diffusing plate 30 are rotated to a third preset position, the first air diffusing plate 20 and the second air diffusing plate 30 are dislocated, and There is a gap between the first diffuser 20 and the second diffuser 30.

In this embodiment, by providing a gap between the first air diffusing plate 20 and the second air diffusing plate 30, while blocking the air outlet 10, a small amount of cold air can be ensured to flow out from the gap, and the first wind is dispersed. The hot air outside the plate 20 and the second diffuser 30 is blown away to prevent condensed water from being generated on the first diffuser 20 and the second diffuser 30. Specifically, the height of the bottom end surface of the first air diffusing plate 20 in the vertical direction is higher than the top end surface of the second air diffusing plate 30 (in the embodiment, the first air diffusing plate 20 is in the width direction) One end surface of the second air diffusing plate 30 is the bottom end surface of the first air diffusing plate 20; the end surface of the second air diffusing plate 30 adjacent to the first air diffusing plate 20 in the width direction is the second air diffusing plate 30. a top end), a gap between the first louver 20 and the second louver 30, so that ventilation is formed between the inner side of the first louver 20 and the inner side of the second louver 30 The passage allows the wind to be blown back to the outer side of the second diffuser 30, thereby reducing the temperature difference between the two sides of the second diffuser 30 and preventing the generation of condensed water.

The following is a detailed description of a preferred example: when the indoor temperature is less than or equal to the first preset temperature, and the ambient humidity is less than the first preset humidity, the first louver 20 is controlled to rotate to the air outlet 10 The direction of the wind is vertical or substantially vertical to reduce the amount of air. When the indoor temperature is further less than or equal to the second preset temperature, and the ambient humidity is less than the second preset humidity, the second air diffuser 30 is controlled to rotate to a position perpendicular or substantially perpendicular to the air outlet direction of the air outlet 10, To minimize the amount of airflow. It can be understood that, in this example, the second preset position of the first louver 20 is at the same position as the third preset position of the first louver.

It should be noted that the size of the first preset temperature and the second preset temperature may be set according to actual needs. In this embodiment, preferably, in order to consider the influence of the target temperature set by the user on the windless mode, The first preset temperature and the second preset temperature may be adjusted in stages. The target temperature is the target temperature at which the user sets the air conditioning operation.

Specifically, when the set target temperature is greater than the third preset temperature, the first preset temperature is a sum of the target temperature and a preset temperature difference, and the second preset temperature is the target temperature; When the set target temperature is less than or equal to the third preset temperature, the first preset temperature is a first preset threshold, and the second preset temperature is a second preset threshold.

The following preset temperature is 24 ° C, the preset temperature difference is 2 ° C, the first preset temperature is 26 ° C, and the second preset temperature is 24 ° C as an example for detailed description: when the target temperature Ts is greater than 24 When the temperature is °C, the first preset temperature is Ts+2°C, and the second preset temperature is Ts; when the target temperature Ts is less than or equal to 24° C., the first preset temperature is 26° C., and the second preset temperature is 24 ° C. By setting the first preset temperature and the second preset temperature in stages according to the target temperature, the target temperature is effectively prevented from being too low, and the indoor temperature cannot reach a condition smaller than Ts+2 °C.

Further, the controller controls the first air diffuser 20 and the second air diffuser 30 to increase the airflow of the air outlet 10, including:

When the air conditioner indoor unit is in the third preset position, the controller determines whether the current ambient humidity is greater than a first preset value; if yes, the controller controls the The first air diffusing plate 20 is rotated to a second preset position, and the second air diffusing plate 30 is controlled to rotate to a first preset position;

When the air conditioner indoor unit is located at the second preset position of the first air diffusing plate 20 and the second air diffusing plate 30 is located at the first preset position, the controller determines whether the current ambient humidity is greater than the second a preset value; if yes, the controller controls the first louver 20 to rotate to a first preset position; the first preset value is less than a second preset value.

In this embodiment, the first air diffusing plate 20 and the second air diffusing plate 30 are located in three different states as shown in FIGS. 1 to 3. In the first state shown in FIG. 1, the first air diffusing plate 20 and the second air diffusing plate 30 are in a fully open state, wherein the first air diffusing plate 20 and the second air diffusing plate 30 are both located in the first preset. Position; in the second state shown in FIG. 2, the first air diffusing plate 20 partially blocks the air outlet 10, wherein the first air diffusing plate 20 is located at the second preset position, and the second air diffusing plate 30 is located at the first preset Position; in the third state shown in FIG. 3, the first air diffusing plate 20 and the second air diffusing plate 30 cooperate to block the air outlet 10 to minimize the air volume, wherein the first air diffusing plate 20 and the second The diffuser panels 30 are all located at a third preset position.

Specifically, after entering the windless mode, firstly, the first air diffusing plate 20 and the second air diffusing plate 30 are controlled to move to the first state, and after running for a period of time in the first state, it is then determined whether the first The preset condition; if so, the first louver 20 and the second louver 30 are controlled to move to the second state. In the second state, determining whether the second preset condition and the ambient humidity are greater than the second preset value, and when the second preset condition is met, controlling the first air diffuser 20 and the second air diffuser 30 to enter the first The three states; when the ambient humidity is greater than the second preset value, the first louver 20 and the second louver 30 are controlled to enter the first state. In the third state, whether the ambient humidity is greater than the first preset value, and when the ambient humidity is greater than the first preset value, the first air diffuser 20 and the second air diffuser 30 are controlled to enter the second state. In this embodiment, determining whether the first preset condition is met, whether the second preset condition is met, whether the ambient humidity is greater than the second preset value, and whether the ambient humidity is greater than the first preset value is set. The difference value may also be set. For example, the second preset value may be 75%, the first preset value may be 70%, and the first preset condition is: the indoor temperature is less than or equal to 26 ° C and the ambient humidity is less than 65. %, the second preset condition is: the indoor temperature is less than or equal to 24 ° C and the ambient humidity is less than 60%.

Further, when referring to FIG. 4 and FIG. 5 together, when the air conditioner indoor unit opens the air outlet 10 in the first air diffusing plate 20 and the second air diffusing plate 30, the controller determines the current environment. Whether the humidity is greater than a third preset value; if so, when the air deflector 60 of the air conditioner indoor unit blocks the air outlet, the air deflector 60 is controlled to open the air outlet 10.

In this embodiment, if the indoor humidity still rises after the first air diffusing plate 20 and the second air diffusing plate 30 enter the first state, the condensed water is likely to be generated, and at this time, it is necessary to appropriately increase the interval according to the humidity rise. The outlet angle of the large inner fan increases the air volume, and blows the condensed water on the first diffuser 20 and the second diffuser 30 to maintain the drying effect of the diffuser. As shown in FIG. 4 and FIG. 5 , specifically, at this time, it can be determined whether the air deflector 60 completely opens the air outlet 10 , and if the air deflector has a shielding air outlet 10 (as shown in FIG. 4 ), the wind guide is controlled. The plate 60 opens the air outlet 10 (shown in Figure 5) to increase the amount of air.

The present invention also provides an air conditioning indoor air outlet control method, which is applied to the above air conditioning indoor unit, with reference to FIG. 1 to FIG. 6 . In an embodiment, the air conditioning indoor air outlet control method provided by the present invention includes:

Step S10, in the cooling operation state of the air conditioner indoor unit, after entering the preset operation mode, controlling the first air diffusing plate 20 and the second air diffusing plate 30 to be at different rotating positions to form an occlusion of the air outlet 10, Changing the gap of the air outlet 10 for air outlet;

In step S20, it is determined whether to control the rotation of the first air diffusing plate 20 and the second air diffusing plate 30 according to the ambient humidity detected by the humidity detector, so that the air outlet 10 is used for increasing the gap of the air outlet.

Specifically, after entering the windless mode, the control method of controlling the first air diffusing plate 20 and the second air diffusing plate 30 to cooperate to reduce the air volume of the air outlet 10 to different degrees may be set according to actual needs. For example, it is possible to control the amount of air blown from the air outlet 10 in accordance with the temperature and the ambient humidity. Specifically, when the indoor temperature and the ambient humidity are lower, the amount of wind that fits the first first air diffusing plate 20 and the second air diffusing plate 30 in the room is larger, and the amount of air discharged from the air outlet 10 is smaller. The smaller the amount of air blown from the air outlet 10, the smaller the air flow speed of the environment, thereby improving the comfort of the environment. If the ambient humidity is increased after the air volume is reduced, it is easy to generate condensed water on the first and second diffuser plates. At this time, it is necessary to judge whether it is necessary to return to the state before the air volume adjustment according to the environmental humidity, so as to improve The amount of air discharged from the air outlet 10 avoids the generation of condensed water on the first and second diffuser plates.

In the embodiment of the present invention, after reducing the air volume of the air outlet 10, it is determined in real time whether the air volume of the air outlet 10 needs to be increased according to the environmental humidity, and the state of the first air diffusing plate 23 and the second air diffusing plate 30 is changed to improve the state. The air outlet amount of the air outlet 10 effectively prevents hot air from collecting on the outer side surface of the air diffusing plate, thereby effectively preventing the occurrence of condensed water.

Further, referring to FIG. 7, according to the first embodiment of the air conditioning indoor air outlet control method of the present invention, in the second embodiment of the air conditioning indoor air outlet control method of the present invention, the first air diffuser and the second air conditioner are controlled. The air diffusing plate reduces the air volume of the air outlet:

Step S11, after entering the preset operation mode, controlling the first louver 20 and the second louver 30 to rotate to a first preset position to open the air outlet 10;

Step S12, when the first preset condition is met, the first louver 20 is controlled to rotate to a second preset position to partially block the air outlet 10;

Step S13, when the second preset condition is met, the first louver 20 and the second louver 30 are controlled to rotate to a third preset position, and the first louver 20 and the second louver 30 are mutually connected. Cooperate to block the air outlet 10.
