Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 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 including a middle frame 110, an air outlet 111 provided on the middle frame 110, an air guide plate 130 provided at the air outlet 111 of the middle frame 110, and a front panel 120 movably provided at the middle frame 110, the air guide plate 130 being in a horizontal blowing state in an initial state, the front panel 120 being restored to the middle frame 110, the multi-mode switching method comprising the steps of:
Step S11, entering a rapid refrigeration mode, wherein the rapid refrigeration mode comprises the movement of the front panel 120 and the increase of the opening and closing degree of the air outlet 111, and the air deflector 130 performs swinging operation;
Step S12, if a first preset condition is triggered, entering a horizontal air outlet mode, wherein the horizontal air outlet mode comprises returning the air deflector 130 to an initial state;
Step S13, if the second preset condition is triggered, entering a stealth wind mode, wherein the stealth wind mode includes the movement of the front panel 120 and minimizes the opening and closing degree of the air outlet 111.
Specifically, regarding the air conditioning structure, the front panel 120 may move on the front end surface of the middle frame 110, preferably, move back and forth and move up and down, an air outlet duct is formed between the front panel 120 and the front end surface of the middle frame 110 in the forward moving process, and the air blown out by the air outlet 111 is blocked by the front panel 120 and blown into the air outlet duct, and then blown out along the edge of the front panel 120, so as to control the air inlet of the air outlet duct by controlling the movement of the front panel 120 and adjusting the spatial position; and, the front panel 120 moves up and down when moving forward to the farthest distance, and gradually opens the air outlet 111 during the upward movement, i.e. increases the opening and closing degree of the air outlet 111. The air deflector 130 can perform large-angle movement on the middle frame 110 to change the direction of the wind blown by the air outlet 111, so as to meet the requirements of wind directions in different functional modes. Wherein, the air deflector 130 is in a horizontal blowing state, which means that the rear end edge of the lower air deflector 130 abuts against the lower end edge of the air outlet 111, and the air blown out by the air outlet 111 flows along the air deflector 130; the homing of the front panel 120 to the center frame 110 means that the front panel 120 rests against the front face of the center frame 110.
The actual purpose of the multi-mode switching method is to effectively combine three refrigeration modes for intelligent refrigeration, and effectively combine the three modes of high-efficiency refrigeration, temperature maintenance and power consumption reduction, namely effectively combine a quick refrigeration mode, a horizontal air outlet mode and a invisible air mode. And through the movement of the front panel and the air deflector and multi-mode switching, the risk of the current condensation can be judged based on parameters such as temperature and/or humidity, wind speed, wind quantity and the like, and corresponding mode or gear switching (can also be combined with compressor frequency adjustment) is provided, so that the condensation problem of the air conditioner is solved, and the excessive frequency reduction of the compressor is avoided, and the cold quantity is sacrificed.
Referring to fig. 2 and 3, the rapid 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, more cold air is blown out from the air outlet 111 and cannot be blocked, the cooling effect is improved, and the air deflector 130 is turned in place and then swings, so that the blown cold air is guided to disturb the ambient air flow, the cold air flows in the environment more quickly, and the cooling efficiency is improved. Referring to fig. 4, the horizontal air-out mode keeps the front panel 120 moving 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, more cold air is blown out from the air outlet 111 and is not blocked, the refrigerating effect is improved, and meanwhile, the air deflector 130 rotates back to the initial state, so that the air blown out from the air outlet 111 is blown out horizontally. Referring to fig. 5, the invisible wind mode moves on the front panel and minimizes the opening and closing degree of the air outlet, that is, the wind blown out by the air outlet 111 is blown into the air outlet duct, so as to realize a soft wind state, and comfortable wind is blown out while maintaining the ambient temperature.
In this embodiment, when the user defines the fan rotation speed, the swing mode of the air deflector 130, the control gear, the swing mode of the swing blade, or the target temperature, the user exits the action corresponding to the multi-mode switching method and performs the user-defined action. With the preference of user selection, although the fan rotation speed, the swing mode of the air deflector 130, the control gear, the swing mode of the swing blade or the target temperature which are already set are all optimal schemes for realizing intelligent refrigeration in the multi-mode switching method, due to different requirements of users, if the users want to refrigerate faster, or the refrigeration efficiency is reduced, the wind speed is not too high, or the wind is required to blow towards one direction, and the like, the intelligent refrigeration system can be correspondingly adjusted according to the user-defined operation. Wherein, the fan rotational speed represents the rotational speed of air conditioner fan.
In this embodiment, in step S11, after entering the rapid cooling mode, the air deflector 130 and the front panel 120 return to the initial state again. The front panel 120 and the air deflector 130 can be matched better synchronously, and particularly, as the front panel 120 and the air deflector 130 are controlled by corresponding motors, the different positions of the front panel 120 and the air deflector 130 can be moved by controlling the rotation angle of the motors. Of course, the front panel 120 and the air deflector 130 may continue to move to a position where rapid cooling can be achieved without returning to the initial state, and in this way, the requirements on cooperation are higher, but the overall control flow is more efficient and faster.
As shown in fig. 2, 3, 4, 6 and 7, the present invention provides a preferred embodiment of the fast cooling mode.
Referring to fig. 6, the step of step S11 further includes:
step S111, entering a fast cooling mode, wherein the front panel 120 moves and increases the opening and closing degree of the air outlet;
step S112, the air deflector 130 swings and maintains a second preset time;
step S113, the air deflector 130 returns to the initial state and maintains the second preset time;
Step S114, the steps S112 and S113 are repeatedly looped.
Specifically, referring to fig. 2 to 4, in order to achieve rapid cooling, the purpose is to make more cool air blow out from the air outlet 111, and since the air conditioner has a front panel 120 structure or makes the air blown out from the air outlet 111 blow out along the air outlet duct, the front panel 120 moves up when entering the rapid cooling mode or moves up again when moving forward furthest, so that the opening and closing degree of the air outlet 111 is sufficiently large and more cool air is blown out from the air outlet 111. And, not only need to make more cold wind blow out from air outlet 111 fast, still need to blow out cold wind and flow in order to disturb the ambient air current, make cold wind flow in the environment more fast, improve refrigeration efficiency, and because the special design of aviation baffle 130, aviation baffle 130 rotation axle center is the top of aviation baffle 130 up end, be 180 degrees or be the rotation that is close 180 degrees after upset in place, aviation baffle 130 should be in air outlet 111's intermediate position, the wind that air outlet 111 blown out is flowed towards aviation baffle 130's angular direction under the effect of aviation baffle 130, through the swing operation of aviation baffle 130, make the wind that flows blow out in different angles, in maintaining the second default time, realize extensive air disturbance. And, after the air deflector 130 swings and maintains the second preset time, the air deflector 130 needs to be turned back to the initial state.
In this embodiment, referring to fig. 7, a plurality of first control gears based on temperature differences are preset, and each first control gear is provided with a corresponding fan rotation speed; the step S11 further includes:
Step S1111, entering a rapid cooling mode, moving the front panel 120 and increasing the opening and closing degree of the air outlet 111, and selecting a first control gear with the maximum fan rotation speed;
Step S1112, controlling the air outlet 111 to blow out wind corresponding to the rotation speed of the fan;
Each first control gear is provided with a corresponding preset variable, and the corresponding first control gear is selected according to different preset variables; the preset variables are at least one of temperature difference, time, humidity, temperature and humidity, human body temperature, number of people, individual difference and physiological condition.
Preferably a temperature difference, i.e. the difference between the ambient temperature and the target temperature. Specifically, the smaller the temperature difference of the different first control gears is, the smaller the corresponding fan rotating speed is. Under the independent rapid refrigeration mode, the current temperature difference can be obtained according to the detected ambient temperature, and the set first control gear is selected, so that the air conditioner is controlled to blow out wind with different fan speeds, the energy consumption is reduced before the rapid refrigeration is completed, and excessive refrigeration can be prevented. However, in the multi-mode switching method, the largest first control gear is directly selected, and the first control gear may refer to the following table (in which RPM represents the rotational speed of the fan):
| Temperature difference | First control gear | Fan speed |
| Greater than 3 degrees | Fourth gear position | Strong wind speed (1200 RPM) |
| Greater than 2 degrees | Third gear position | High wind speed (1000 RPM) |
| Greater than 1 degree | Second gear | Middle wind speed (900 RPM) |
| Less than 1 degree | First gear position | Low wind speed (800 RPM) |
In step S1111, the fourth gear of the first control gear is selected, i.e., the strong wind speed is blown out from the air outlet 111, so as to realize rapid cooling.
