As patent (CN204388229U) discloses a built-in air conditioner, which comprises: the air conditioner comprises a shell, wherein an air inlet and an air outlet are formed in the shell, the air outlet is arranged around the air inlet, and the air outlet comprises a main air outlet and an auxiliary air outlet communicated with the main air outlet; the air inlet grille is arranged on the shell and is positioned at the air inlet; the air deflector is arranged on the outer side of the air inlet grille and is positioned at the main air outlet; and the cover plate is arranged on the shell, and the auxiliary air outlet is limited between the cover plate and the shell. In the scheme, the auxiliary air outlet is used as a supplement of the main air outlet and is mainly used for eliminating air supply dead angles which are not in the air supply range of the main air outlet. That is, the above improvement of the scheme is to add a new air supply form mainly by introducing a new component, and the improvement of the new air supply form on the whole air supply amount and the air supply direction is very limited.
Accordingly, there is a need in the art for a new outlet adjustment solution to solve the above problems.
Disclosure of Invention
In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the air output and the air supply direction of the air outlet of the existing indoor unit of an air conditioner are to be further improved, the present invention provides an air outlet adjusting method of an indoor unit of an air conditioner, on one hand, the indoor unit of an air conditioner includes a body, an air supply unit disposed in the body, and a panel frame disposed at the bottom of the body, a fixed air outlet structure is disposed on the panel frame, a movable air outlet structure capable of extending and retracting between a highest stroke point and a lowest stroke point along an axial direction of the body is disposed in the body, the fixed air outlet structure and the movable air outlet structure form an air outlet of the indoor unit of the air conditioner, and the air supply unit is capable of supplying cold air to the air outlet, and the air outlet adjusting method includes: under the condition that the indoor unit of the air conditioner is in a refrigeration working condition, acquiring an ambient temperature and comparing the ambient temperature with a preset threshold value; determining the axial position and/or the movement posture of the movable air outlet structure along the machine body according to the comparison result; and determining the air supply parameters of the air supply unit according to the comparison result.
The invention realizes the change of the air output and the air supply direction of the air outlet through the adjustment of the air supply parameters of the air supply unit and the axial extension of the movable air outlet structure along the machine body. Particularly, the change of air supply volume and air supply direction has been realized through same air outlet, makes the air supply scope of air outlet can adjust in a flexible way. The highest stroke point and the lowest stroke point are points capable of representing the highest position and the lowest position of the movable air outlet along the axial direction of the machine body, such as but not limited to: the highest stroke point and the lowest stroke point are respectively the intersection points of the movable air outlet and the axis of the machine body when the movable air outlet is at the highest position and the lowest position along the axial direction of the machine body. Preferably, the movable air outlet structure is substantially flush with the fixed air outlet structure at the highest stroke point.
Under the condition that air supply parameters are not changed, in the process that the movable air outlet structure moves downwards from the uppermost position, namely the highest point of the stroke, to the lowermost position, namely the lowest point of the stroke, the air supply amount of the air outlet can be increased, the boundary of the air outlet at the radial outer side and the radial inner side can be enlarged, particularly the air direction of the part close to the radial inner side can be gradually changed into steep, and therefore the problem of dead angles of air supply can be solved within a certain range according to different air supply requirements. And along with the removal of activity air-out structure, to same target windward point, even do not belong to the air supply dead angle from beginning to end, the air supply direction also changes, consequently can satisfy diversified air supply demand. The air supply parameters and the adjustment mode of the movable air outlet structure are determined through the ambient temperature, so that the air supply quantity of the air outlet and the adjustment mode of the air supply mode can better meet the real air supply requirement of a user, the user experience is improved, and the overall air outlet performance is improved.
In a preferred technical solution of the above-mentioned air outlet adjusting method, "the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body is determined according to the comparison result; and the step of determining the air supply parameter of the air supply unit according to the comparison result comprises the following steps: when the difference value between the ambient temperature and the preset threshold value is larger than a first preset value, the indoor unit of the air conditioner is enabled to operate in a first air outlet mode; the first air outlet mode is that the movable air outlet is continuously located at a position corresponding to the highest stroke point, and the air supply unit is operated according to a first air supply parameter.
The cold air flow mainly comprises a relatively gentle cold air flow and a relatively steep cold air flow. Wherein steep cold air flow is directly blown to the ground and gentle cold air flow is spread out at the position near the upper part of the indoor space. Because the density of the cold air is greater than that of the hot air, the steep cold air flow quickly falls to the ground in a form close to a cold air column, and therefore, only the heat exchange with the local hot air in the indoor space is realized, and the heat exchange is insufficient. After the relatively gentle cold air flow is sent into the indoor space, the relatively gentle cold air flow is firstly sent to a far place from the vicinity of the height of the ceiling to form a relatively large-area cold air surface, and the cold air surface slowly falls to the ground to exchange heat with hot air of each layer, so that the hot air of all layers in the indoor space is fully cooled. After the cold and heat exchange, the cold quantity obtained by the air close to the air outlet in the indoor space is slowly and gradually diffused, so that the whole indoor space is refrigerated. In the case where the movable outlet is continuously located at a position corresponding to the highest stroke point (hereinafter, referred to as state a), the cooling demand is highest, and thus the required amount of air supply is as large as possible and the cool airflow includes as much gentle cool airflow as possible. At the moment, the air supply quantity is enabled to be as large as possible by adjusting the operation parameters of the air supply motor. Through such air-out adjustment mode, guarantee that the air supply volume is the biggest in each mode and have the mild air conditioning of bigger proportion in the air conditioning to because the air outlet is narrow and the air supply volume is big, consequently mild air conditioning can be "sent" farther, can form bigger cold air face, thereby can make the air of interior space can realize the refrigeration fast, comprehensively.
In a preferred technical solution of the above-mentioned air outlet adjusting method, "the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body is determined according to the comparison result; and the step of determining the air supply parameter of the air supply unit according to the comparison result comprises the following steps: when the difference value between the ambient temperature and the preset threshold value is greater than a second preset value and less than or equal to the first preset value, the indoor unit of the air conditioner is enabled to operate in a second air outlet mode; the second air outlet mode is that the movable air outlet reciprocates between the highest stroke point and a boundary stroke point below the highest stroke point, and the air supply unit operates according to a second air supply parameter; when the air supply unit operates according to the second air supply parameter, the air supply quantity of the cold air flow supplied to the air outlet is smaller than the first air supply parameter.
In a preferred technical solution of the above-mentioned air outlet adjusting method, "the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body is determined according to the comparison result; and the step of determining the air supply parameter of the air supply unit according to the comparison result comprises the following steps: when the difference value between the ambient temperature and the preset threshold value is greater than a third preset value and less than or equal to the second preset value, enabling the indoor unit of the air conditioner to operate in a third air outlet mode; the third air outlet mode is that the movable air outlet is continuously positioned at a position corresponding to the demarcation travel point, and the air supply unit is operated according to a third air supply parameter; and when the air supply unit operates according to the third air supply parameter, the air supply quantity of the cold air flow supplied to the air outlet is smaller than the second air supply parameter.
In the case where the movable outlet is continuously in the position corresponding to the demarcation travel point (hereinafter referred to as state C), the refrigeration demand is reduced but still greater. In the case of a reciprocating movement of the movable outlet between the highest point of travel and the dividing point of travel (hereinafter referred to as state B), the refrigeration requirement lies between states a and C. In the state C, the amount of air supply is reduced but still large by adjusting the operation parameters of the air supply motor, but the air supply direction is adjusted at this time, specifically, the portion of the gentle airflow on the radial inner side tends to be steep as the air outlet increases. That is, in the state C, the total amount of the cool airflow is decreased and the proportion of the steep cool airflow is increased, so that the total cooling capacity obtained from the indoor space is decreased, and the time period for which the cooling capacity is uniformly diffused to the indoor space, that is, the achievement time period of the cooling demand is increased. Compared with the state C, the air supply quantity and the gentle airflow proportion of the state B are both between the state A and the state C by adjusting the operation parameters of the air supply motor, and the diffusion of cold airflow sent into the indoor space is increased by the reciprocating motion of the movable air outlet structure. And for the same target windward point, the air supply directions at different moments are different, so that the cold quantity is promoted to be diffused in the indoor space through collision and superposition of cold air flows at different moments and in different directions.
Through setting up of boundary stroke point, can refine the stroke control of activity air-out structure under the different air-out modes better. For the same target windward point, the downward movement of the boundary travel point can increase the air supply amount of the cold air flow obtained in the (second and third) air outlet modes (corresponding to the states B and C) (under the condition that the operation parameters of the air supply motor are not changed), and the air supply direction becomes steep; the upward movement of the boundary travel point can reduce the air supply amount of the cold air flow obtained in the (second and third) air outlet modes (under the condition that the operation parameters of the air supply motor are not changed), and the air supply direction can become gentle.
In a preferred technical solution of the above-mentioned air outlet adjusting method, "the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body is determined according to the comparison result; and the step of determining the air supply parameter of the air supply unit according to the comparison result comprises the following steps: when the difference value between the ambient temperature and the preset threshold value is greater than a fourth preset value and less than or equal to the third preset value, enabling the indoor unit of the air conditioner to operate in a fourth air outlet mode; the fourth air outlet mode is that the movable air outlet reciprocates between the lowest stroke point and the highest stroke point, and the air supply unit operates according to fourth air supply parameters; when the air supply unit operates according to the fourth air supply parameter, the air supply quantity of the cold air flow supplied to the air outlet is smaller than the third air supply parameter.
In a preferred technical solution of the above-mentioned air outlet adjusting method, "the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body is determined according to the comparison result; and the step of determining the air supply parameter of the air supply unit according to the comparison result comprises the following steps: when the difference value between the preset threshold and the ambient temperature is less than or equal to the fourth preset value, enabling the indoor unit of the air conditioner to operate in a fifth air outlet mode; the fifth air outlet mode is that the movable air outlet is continuously positioned at a position corresponding to the lowest stroke point, and the air supply unit is operated according to fifth air supply parameters; when the air supply unit operates according to the fifth air supply parameter, the air supply quantity of the cold air flow supplied to the air outlet is smaller than the fourth air supply parameter.
In the case where the active outlet is continuously in the position corresponding to the lowest travel point (hereinafter referred to as state E), the refrigeration demand is the lowest. In the case where the active outlet is reciprocating between the highest and lowest travel points (hereinafter referred to as state D), the refrigeration demand is greater than state E. In the state E, a small amount of relatively gentle cold air flow is firstly blown to the upper position of the indoor space to form a cold air surface, then the hot air is cooled in the falling process, and the obtained cold energy is slowly and gradually diffused, so that the whole indoor space can meet the refrigeration requirement of a relatively small amplitude (the total cold energy is relatively low, and the achievement duration of the refrigeration requirement is relatively long). Compared with the state E, the air supply amount (combining the position adjustment of the movable air outlet and the rotating speed adjustment of the air outlet motor) and the gentle air flow proportion of the state D are both larger than those of the state E, and in the stage that the movable air outlet reciprocates between the boundary travel point and the highest travel point, the air supply amount and the gentle air flow proportion are both smaller than those of the state C. Through the reciprocating motion of the movable air outlet structure in the maximum stroke range, the diffusion of cold air flow after being sent into the indoor space is increased. And for the same target windward point, the air supply directions at different moments are different, so that the cold quantity is promoted to be diffused in the indoor space through collision and superposition of cold air flows at different moments and in different directions. However, since the range of the reciprocating stroke at this time is large, the degree of such collision and superimposition also varies greatly, and specifically, the average severity level of collision and superimposition is reduced as compared with the above-described state B, and therefore the overall cooling demand is smaller than that in the state B.
In a preferred embodiment of the above-described wind outlet adjustment method, an absolute value of a difference between a distance between the maximum stroke point and the boundary stroke point and a distance between the boundary stroke point and the minimum stroke point is not greater than 1/5 of a distance between the maximum stroke point and the minimum stroke point.
In a preferred embodiment of the above-described ventilation adjusting method, a distance between the maximum stroke point and the division stroke point is equal to a distance between the division stroke point and the minimum stroke point.
Having the demarcation trip point near the midpoint of the highest trip point and the lowest trip point, the difference between the different modes is more obvious from the user's perspective, making the mode differentiation more meaningful and more capable of providing different degrees of refrigeration demand closer to the user's expectations. Preferably, the demarcation trip point is above the midpoint to meet the needs of the user in situations where refrigeration needs are greater.
In a preferred technical scheme of the air outlet adjusting method, the air supply unit comprises an air outlet motor and a fan connected with the air outlet motor, and the air supply parameter is an operation parameter of the air outlet motor.
For example, the operation parameters may include, but are not limited to, a rotation speed of the wind outlet motor, an angular acceleration, a wind blowing time at the corresponding rotation speed and angular acceleration, etc., and the rotation speed, the angular acceleration, the wind blowing time at the corresponding rotation speed and angular acceleration, etc., may be changed by adjusting the frequency. Through adjusting the operating parameter to the air-out motor, can realize adjusting the air output. For example, for the same target windward point, under the condition that other conditions are not changed, when the rotating speed of the wind outlet motor is increased by changing the frequency of the wind outlet motor, the air supply amount in the unit time is increased, so that the target windward point can have more obvious cold feeling. For example, the rotating speed of the wind outlet motor can be increased along with the increase of the refrigeration requirement, and the rotating speed in each wind outlet mode can be equal or unequal. It can be understood that the air supply amount can be more flexibly adjusted for different air outlet modes on the premise of not deviating from the refrigeration requirement.
The invention provides an air conditioner indoor unit, which comprises a control unit, wherein the control unit is used for executing the air outlet adjusting method in any one of the schemes. The air conditioner indoor unit has all the technical effects of the air outlet adjusting method, and the details are not repeated herein.
