The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The invention is explained in detail below with reference to the figures and with reference to exemplary embodiments.
As shown in fig. 1 to 4, the utility model discloses at first a structure that sets up two air outlets in air conditioning indoor unit sets up, bottom at air conditioning indoor unit casing 1 is provided with two wind gap structures, first air outlet 31 and second air outlet 41 are arranged in the front and back side and are separated, through the setting to first wind-guiding part 34 and second wind-guiding part 44 above first air outlet 31 and the second air outlet 41, can realize for the more humanized upper and lower air supply of traditional air supply to increase the comfort level that the user used the air conditioner.
The temperature of the air flow sent out from the air outlet of the conventional air conditioner on-hook is single, and the refrigerating or heating air flow is directly blown to the body, so that the poor feeling of supercooling or overheating can be brought to a user. For example in summer, the air conditioner opens behind the cooling mode of a period, can feel that the air that blows off is very cold, but turns off the air conditioner and will feel that indoor temperature has gone up again very fast, the utility model discloses the fine solution this problem.
For example, in summer, a user has an urgent need for using an air conditioner for refrigeration, because the room temperature is high, after the air conditioner is started, a general compressor is started at a high frequency for refrigeration after the temperature difference condition is judged, and because the air conditioner is just started and the indoor temperature is high, the blowing angle of the air conditioner is basically designed to be a standard angle of a refrigeration mode, so that cold air blown out by a heat exchanger can reach a farther distance, and the air conditioner sinks due to the density of the air conditioner to enable the temperature of a room to be more uniform, so that the purpose of rapid refrigeration is achieved. At this time, as shown in fig. 2, the opening angle of the first deflector 341 of the first outlet 31 with respect to the tangential direction of the air-conditioning panel is generally between 10 ° and 75 °, and the second deflector 442 and the third deflector 443 of the second outlet 41 are in a parallel state, and the outlet air direction of the second outlet 41 is substantially the same as the outlet air direction of the first outlet 31.
However, after the air conditioner is turned on for a certain period of time, the indoor temperature drops to the user's set temperature, which is determined according to the comfortable temperature, so that the user feels cold and uncomfortable if the cool air with a low temperature is continuously blown through the heat exchanger. As shown in fig. 4, in the embodiment of the present invention, the first air guiding part 34 disposed at the first air outlet 31 continues to blow the cool air upward so as to keep the indoor temperature at a lower state, and the air outlet angle disposed at the first air outlet 31 in other embodiments is higher, and the air outlet speed is larger, so as to keep the indoor temperature not to rise any more. The second air guiding component 44 of the second air outlet 41 is further disposed, and the direction of the outlet air is changed by the cooperation of the second air guiding plate 442 and the third air guiding plate 443 in the second air guiding component, so as to prevent cold air from directly blowing on a human body, on the other hand, in this embodiment, the outlet air temperature of the second air outlet is closer to the set temperature by disposing the second air supply module 4, and the outlet air angle of the second air outlet 41 is lower, and the outlet air speed is smaller, so that the comfort level can be further improved, therefore, in this specification, the outlet air angle of the first air outlet 31 and the outlet air angle of the second air outlet 41 are separately controlled, and a state where the outlet air temperature of the first air outlet 31 is different from the outlet air temperature of the second air outlet 41 is referred to as a dual temperature control state, and, in the following description, the first air outlet 31 is referred to as an upper air outlet, the second outlet 41 is referred to as a lower outlet, and is only for convenience of description, and the specific orientation of the two is not limited in other embodiments, for example, in some embodiments, the first outlet 31 or the second outlet 41 is on the side of the air conditioning casing 1, and for example, the two are vertically distributed, and the like.

Or in the heating mode, when the air flows through the first group of heat exchange parts 211, the air carries higher temperature to keep the indoor temperature from dropping. In other words, the first group of heat exchange parts keeps a high heat exchange rate, and simultaneously ensures the cooling and heating effects of the air conditioner, when the room temperature approaches the set temperature of the user, the airflow flowing out of the upper air outlet swings upwards, so that the overcooled or overheated airflow is not directly blown to the body of the user.

in short, by controlling the first air guiding member 34 and the second air guiding member 44, for example, the first air blowing module 3 can guide air to the left and the second air blowing module 4 can guide air to the right, or the first air blowing module 3 can guide air to the right and the second air blowing module 4 can guide air to the left, or the first air blowing module 3 can guide air to the left and the second air blowing module 4 can guide air to the right, or the first air blowing module 3 can guide air to the right and the second air blowing module 4 can guide air to the left and the like, so that the partition of the upper, lower, left and right areas can be realized. Meanwhile, the first throttling element 23 and the second throttling element 24 are matched to control the flow of the refrigerant in the first group of heat exchange portions 211 and the second group of heat exchange portions 212, so that the air supply temperature of the first air supply module 3 and the second air supply module 4 is controlled, and the purpose of temperature control in a subarea mode is further achieved.
In addition, as shown in fig. 1 to 4, a partition plate 5 is provided in the casing 1, and the partition plate 5 is spaced between the air inlet side of the first air supply module 3 and the air inlet side of the second air supply module 4. It will be appreciated that the primary purpose of the baffle 5 is to prevent air cross-flow.
Further, as shown in fig. 1 to 4, a heating element 6 is provided at least at one of the air inlet side of the first air supply module 3 and the air inlet side of the second air supply module 4. In the heating mode, for better heating effect and to prevent the occurrence of cold wind during the initial heating, the heating element 6, which may also be referred to as electric auxiliary heating, is basically added in the air duct, but specifically in this embodiment, it is better to add inside the second air duct 41, because the second air duct 41 is distributed downward, and is responsible for supplying air downward in the dual temperature control state, and to add inside the second air supply module 4 to prevent the occurrence of cold wind.
