Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
Please refer to fig. 1 to 3 for an embodiment of an air conditioner indoor unit according to the present invention, wherein fig. 1 to 3 are schematic structural diagrams of the air conditioner indoor unit in a first state, a second state and a third state, respectively. Specifically, fig. 1 is a schematic structural view of the air deflector in the air guiding assembly in a closed state, fig. 2 is a schematic structural view of the second air deflector 52 in the air deflector in a first position and the indoor unit in a rapid heat exchange state, and fig. 3 is a schematic structural view of the auxiliary air outlet 8 formed and the indoor unit in an anti-condensation state.
As shown in fig. 1, the indoor unit of the air conditioner in this embodiment includes an air outlet 1, a front air duct sidewall 3 and a rear air duct sidewall 4 forming an air outlet duct 2 of the indoor unit. The heat exchange air after heat exchange by a heat exchanger (not labeled in the figure) in the indoor unit is blown to the indoor through the air outlet duct 2 and the air outlet 1 under the action of an indoor fan, such as a cross-flow fan, so that the indoor air is adjusted. An air guide assembly is formed at the air outlet 1 and comprises at least two sections of air guide plates. Specifically, in the embodiment, the air guiding assembly includes two air guiding plates, namely a first air guiding plate 51 and a second air guiding plate 52. The first air deflector 51 is close to the air duct front side wall 3, the second air deflector 52 is close to the air duct rear side wall 4, and when the first air deflector 51 and the second air deflector 52 are in the closed state shown in fig. 1, the two air deflectors are arranged in sequence and close the air outlet 1. That is, the first and second deflectors 51 and 52 form an integrated deflector that closes/opens the outlet 1. The indoor unit further comprises an air inducing piece 6, and particularly in the embodiment, the air inducing piece 6 is an air inducing plate. The air inducing piece 6 is formed outside the air outlet 1 and close to the second air deflector 52, and an air inducing duct 7 is formed between the remaining second air deflectors 52 of the air inducing piece 6.
When the indoor unit works, the air outlet 1 blows out heat exchange air, and when the heat exchange air is blown out forwards from the air outlet 1, a certain negative pressure is generated in the air inducing duct 7. Under the action of negative pressure, non-heat exchange air outside the indoor unit is guided to the air outlet 1 from the air guide channel 7 under the carding of the air guide channel 7, and is mixed with the heat exchange air blown out from the air outlet 1 at the air outlet 1 to form mixed air, and the mixed air is sent out in the direction away from the air outlet 1. The mixed air is softer, the mixed air is blown to a human body to feel more comfortable, and the air supply comfort is improved.
As shown in the schematic structural diagram of the indoor unit in fig. 2 in the second state, the second air guiding plate 52 has a first position, and in the first position, the inner air guiding surface 521 of the second air guiding plate 52 is an extension surface of the air guiding surface 41 of the duct rear wall 4. That is, the inner air guide surface 521 of the second air guide plate 52 is arranged to have an air guide surface that is predetermined to coincide with the air guide surface 41 of the duct rear wall 4, and thus the inner air guide surface 521 of the second air guide plate 52 extends to form the air guide surface 41 of the duct rear wall 4.
Because the air guiding assembly is configured to include two air guiding plates, namely, the first air guiding plate 51 and the second air guiding plate 52, the second air guiding plate 52 is close to the air duct rear side wall 4, and the inner air guiding surface 521 of the second air guiding plate 52 is an extending surface of the air guiding surface 41 of the air duct rear side wall 4, so that the second air guiding plate 52 forms the extending surface of the air duct rear side wall 4, then, the second air guiding plate 52 can be used as a part of the air duct rear side wall, and the original air duct rear side wall can be shortened, for example, the length of the second air guiding plate 52 can be shortened to the maximum. Because the air duct rear side wall 4 shortens, according to the air duct air-out theory, after the air duct rear side wall 4 shortens, the static pressure conversion rate of the air-out airflow in the air-out air duct 2 can be reduced, so that the heat exchange airflow blown out from the air outlet 1 has a higher initial speed. And because the induced air duct 7 is formed between the second air deflector 52 and the induced air member 6, after the heat-exchange air with a larger initial speed at the air outlet 1 is blown out, a larger negative pressure is generated in the induced air duct 7, under the action of the larger negative pressure, the non-heat-exchange air outside the indoor unit is guided to the air outlet 1 from the induced air duct 7, mixed with the heat-exchange air at the air outlet 1 to form mixed air, and the mixed air is sent out in the direction far away from the air outlet, so that softer mixed air is sent out. Because the initial speed of the heat exchange air blown out from the air outlet is high, the air quantity of the guided non-heat exchange air is also high, and the large induced air quantity is realized.
When the second air deflector 52 is at the first position, the second state of the indoor unit is a rapid heat exchange state. Specifically, when the second air guiding plate 52 is located at the first position, the second air guiding plate 52, as an extension of the air duct rear side wall 4, can perform a certain diffusion effect on the heat exchange air in the air outlet duct 2 by using the inner air guiding surface 521, effectively solves the problem of air volume loss of the heat exchange air due to the shortening of the air duct rear side wall 4, and ensures that the air outlet 1 can deliver the heat exchange air with a large air volume. And the air quantity of the sent heat exchange air is large, so that the indoor heat exchange can be carried out quickly. Therefore, by using the air conditioner indoor unit of the embodiment, the air is guided by the indoor unit to send soft comfortable air on the basis of ensuring the air guiding quantity and reducing the air supply loss as much as possible.
In a preferred embodiment, in this embodiment, the second air deflector 52 is further configured to be movable relative to the duct rear side wall 4, and by this movement, an auxiliary air outlet 8 is formed between the second air deflector 52 and the duct rear side wall 4 for discharging the air flow in the air outlet duct 2, specifically for discharging the heat exchange air flow. Thus, a schematic structural view of the indoor unit in the third state as shown in fig. 3 is presented. In the schematic structural diagram shown in fig. 3, the second air deflector 52 moves towards the air outlet duct 2 to leave the duct rear wall 4, and forms the auxiliary air outlet 8. In the third state where the auxiliary outlet 8 is formed, in the cooling mode, the heat-exchange cold air blown out from the auxiliary outlet 8 wraps the outer air guide surface (not shown, the other air guide surface opposite to the inner air guide surface 521) of the second air guide plate 52, so that the temperature difference between the inner and outer air guide surfaces of the second air guide plate 52 is reduced, and the second air guide plate 52 is prevented from being exposed to condensation. Therefore, the third state shown in fig. 3 is a condensation prevention state of the indoor unit.
In the third state of condensation prevention, the second air deflector 52 may move relative to the air duct rear side wall 4 by moving towards the inside of the air outlet duct 2 as shown in fig. 3, or may also move relative to the air duct rear side wall by rotating the second air deflector 52 by a rotating shaft (not shown in the figure) located in the air outlet duct 2 as shown in the embodiment of fig. 4, so as to form the auxiliary air outlet 8.
When the indoor unit with the structure is used for supplying air, at least a first state that the air guide plate in the air guide assembly is in a closed state, a second state that the indoor unit is in a quick heat exchange state when the second air guide plate is in the first position and a third state that the indoor unit is in an anti-condensation state when the auxiliary air outlet is formed are provided. For the first state, the state is entered when a shutdown command is received. For the control of the second state and the third state, the following air supply method is preferably adopted:
after the indoor unit is started, the second air deflector 52 is controlled to be at the first position; continuously judging whether set condensation conditions are met;
if the set condensation condition is not met, the second air deflector 52 is continuously controlled to be positioned at the first position so as to realize rapid heat exchange; if the set condensation condition is met, the second air deflector 52 is controlled to move relative to the rear side wall of the air duct to form the auxiliary air outlet 8, so that the air duct enters the condensation prevention state.
Wherein setting the condensation condition may include: the running time of the indoor unit after being started reaches the set time. Wherein the setting time is a known preset time, for example, 15 min.
In this case, satisfying the set condensation condition includes: the running time of the indoor unit after being started up reaches the set time;
and the condition of not meeting the set condensation condition comprises the following steps: the running time of the indoor unit after being started up does not reach the set time.
That is, the timing is started from the start-up operation of the indoor unit, if the operation time after the start-up does not reach the set time, it is determined that the set condensation condition is not met, and the second air deflector 52 is continuously controlled to be at the first position to perform the rapid heat exchange. If the running time after the start-up reaches the set time, the set condensation condition is judged to be met, and in order to prevent condensation, the second air deflector 52 is controlled to move relative to the rear side wall of the air duct to form the auxiliary air outlet 8, so that the air duct enters the condensation-preventing working state.
In other preferred embodiments, the set condensation condition includes that the operation time of the indoor unit after being started reaches the set time and the indoor temperature reaches or approaches the target temperature. Wherein the set time is a known preset time, for example, 15 min; the target temperature is the temperature that can be achieved in the desired room.
In this case, satisfying the set condensation condition includes: the running time of the indoor unit after being started does not reach the set time, but the indoor temperature reaches or approaches the target temperature; or the running time of the indoor unit after being started reaches the set time.
And the condition of not meeting the set condensation condition comprises the following steps: the running time of the indoor unit after being started does not reach the set time and the indoor temperature does not reach or approach the target temperature.
Specifically, the timing is started from the start-up operation of the indoor unit, the current indoor temperature is continuously acquired, and the current indoor temperature is compared with the target temperature. If the running time after the indoor unit is started does not reach the set time, but the indoor temperature reaches or approaches the target temperature, or the running time after the indoor unit is started reaches the set time, the set condensation condition is judged to be met, in order to prevent condensation, the second air deflector 52 is controlled to move relative to the rear side wall of the air duct to form the auxiliary air outlet 8, and the air duct enters the condensation prevention working state. If the running time of the indoor unit after being started does not reach the set time and the indoor temperature does not reach or approach the target temperature, the set condensation condition is judged not to be met, and the second air deflector 52 is continuously controlled to be positioned at the first position to carry out rapid heat exchange.
By adopting the method to control the air supply of the indoor unit, the quick heat exchange and the condensation prevention can be realized, and the air supply performance is improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
