Detailed ways

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 6 , the present invention provides a preferred embodiment of a multi-mode switching method.

A multi-mode switching method of an air conditioner. The air conditioner includes a middle frame 110 , an air outlet 111 arranged on the middle frame 110 , an air guide plate 130 arranged at the air outlet 111 of the middle frame 110 , and an air outlet 110 movably arranged on the middle frame 110 . For the front panel 120, in the initial state, the air deflector 130 is in a horizontal blowing state, and the front panel 120 is returned to the middle frame 110. The steps of the multi-mode switching method include:

Step S11, enter the fast cooling mode, the fast cooling mode includes moving the front panel 120 and increasing the opening and closing degree of the air outlet 111, and the air deflector 130 performs a swing operation;

Step S12, if triggering the first preset condition, enter the horizontal air outlet mode, and the horizontal air outlet mode includes that the wind deflector 130 returns to the initial state;

Step S13 , when the second preset condition is triggered, the invisible wind mode is entered, and the invisible wind mode includes the movement of the front panel 120 and the minimum opening and closing degree of the air outlet 111 .

Specifically, regarding the air conditioning structure, the front panel 120 can move on the front end surface of the middle frame 110, preferably forward and backward and up and down, and the front panel 120 forms an air outlet duct between the front panel 120 and the front end surface of the middle frame 110 during the forward movement process. Part of the air blown out from the air outlet 111 is blocked by the front panel 120 and blows into the air outlet air duct, and then blows out along the edge of the front panel 120, and the movement of the front panel 120 is controlled and the spatial position is adjusted to control the air intake volume of the air outlet duct; And, the front panel 120 moves up and down when it moves forward to the farthest distance, and gradually opens the air outlet 111 during the upward movement, that is, increases the opening and closing degree of the air outlet 111 . The wind deflector 130 can move at a large angle on the middle frame 110 to change the direction of the wind blowing from the air outlet 111 to meet the requirements of the wind direction in different functional modes. The wind deflector 130 is in a horizontal blowing state, indicating that the rear end edge of the lower wind deflector 130 abuts against the lower end edge of the air outlet 111 , and the wind blown out from the air outlet 111 flows along the air deflector 130 ; the front panel 120 returns to its original position. To the middle frame 110 means that the front panel 120 abuts on the front end surface of the middle frame 110 .

The actual purpose of the multi-mode switching method is for intelligent cooling, effectively combining three cooling modes, effectively combining efficient cooling, maintaining temperature and reducing power consumption, that is, effectively combining fast cooling mode, horizontal air outlet mode and invisible air mode. . And, through the movement of the front panel and the wind deflector and multi-mode switching, the current risk of condensation can be judged based on parameters such as temperature and/or humidity, wind speed, and air volume, and the corresponding mode or gear switching can be given (or Combined with compressor frequency adjustment), solve the condensation problem of air conditioners and avoid excessive frequency reduction of compressors and sacrifice cooling capacity.

2 and 3, the fast cooling mode moves through the front panel 120 and increases the opening and closing degree of the air outlet, so that the opening and closing degree of the air outlet 111 is larger, so that more cold air is blown out from the air outlet 111 and does not It can be blocked to improve the cooling effect, and the wind deflector 130 can be turned in place and then swing operation to divert the blown cold air to disturb the ambient air flow, so that the cold air can flow in the environment faster and improve the cooling efficiency. Referring to FIG. 4 , the horizontal air outlet mode keeps the front panel 120 in motion and increases the opening and closing degree of the air outlet, so that the opening and closing degree of the air outlet 111 is larger, so that more cold air is blown out from the air outlet 111 without being blocked, improving the At the same time, the air deflector 130 is rotated back to the initial state, so that the air blown from the lower air outlet is blown out horizontally. Referring to Figure 5, the invisible wind mode moves on the front panel and minimizes the opening and closing degree of the air outlet, that is, the air part of the lower air outlet blows into the air outlet air duct, achieving a soft wind state, maintaining the ambient temperature and blowing out comfortably at the same time. wind of.

In this embodiment, when the user defines the speed of the fan, the swing mode of the wind deflector 130, the control gear, the swing mode of the swing blade, or the target temperature, the action corresponding to the multi-mode switching method is exited and the user-defined action is performed. The user's choice is given priority. Although the fan speed, the swing mode of the wind deflector 130, the control gear, the swing mode of the swing blade or the target temperature are the best solutions for realizing intelligent cooling in the multi-mode switching method, due to the user's Different needs, such as wanting faster cooling, or reducing the cooling efficiency and not wanting too much wind speed, or needing the wind to blow in one direction, etc., can be adjusted according to user-defined operations. The fan speed represents the speed of the air-conditioning fan.

In this embodiment, in step S11, after entering the fast cooling mode, the air deflector 130 and the front panel 120 return to the initial state. It is convenient to make the front panel 120 and the air deflector 130 better synchronously cooperate, especially since the front panel 120 and the air deflector 130 are both controlled by corresponding motors, the rotation angle of the motor can be controlled, so as to realize the front panel 120 and the air deflector Different positions of the plate 130 are moved. Of course, it is also not necessary to return to the initial state, the front panel 120 and the air deflector 130 continue to move in the current position, and move to the position where rapid cooling can be achieved. This method requires higher coordination, but the overall control The process is more efficient and faster.

The multi-mode switching method according to claim 9, wherein the steps of the multi-mode switching method further comprise:

Step S211, comparing the temperature difference with the second preset temperature value;

Step S212, if the temperature difference is greater than the second preset temperature value, re-enter the horizontal air outlet mode;

Step S213 , if the temperature difference is less than the second preset temperature value, re-enter the invisible wind mode.
The multi-mode switching method according to claim 10, wherein the steps of the multi-mode switching method further comprise:

Step S25, when the third control gear is changed, the front panel returns to the initial state;

Step S26, repeating steps S211 to S25.
The multi-mode switching method according to claim 1, wherein: when the user defines the fan speed, the wind deflector swinging mode, the control gear, the swinging blade swinging mode or the target temperature, the action corresponding to the multi-mode switching method is exited. And perform user-defined actions.
The multi-mode switching method according to claim 1, wherein in step S11, after entering the fast cooling mode, the air deflector and the front panel return to the initial state.
