Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

As shown in fig. 1, the embodiment of the present application provides an indoor unit 10, which can solve the technical problems of low thermal comfort and high energy consumption of a fresh air conditioner in the related art.

The indoor unit 10 includes a casing 11, and the casing 11 is provided with a fresh air inlet 111 and at least one fresh air supply end 112 communicated with the fresh air inlet 111. The fresh air inlet 111 can be communicated with the outdoor environment through a fresh air pipe to introduce outdoor fresh air into the indoor unit 10; the fresh air supply end 112 is communicated with the indoor environment to supply the outdoor fresh air in the indoor unit 10 to the indoor environment. The number of the fresh air supply ends 112 may be determined according to actual needs, and may be one or more, and may be independently controlled, which is not limited in the embodiment of the present application.

Here, the fresh air supply end 112 is configured to movably change its fresh air supply state, and the fresh air supply state of the fresh air supply end 112 includes at least one of an air outlet position and an air supply direction of the fresh air supply end 112. The fresh air supply end 112 has freedom of movement, and the spatial position and the attitude angle of the fresh air supply end can be changed through a movement mode. Here, the spatial position and the attitude angle of the fresh air blowing end 112 may be collectively referred to as the attitude of the fresh air blowing end 112.

The air outlet position of the fresh air supply end 112 refers to a position where fresh air leaves the indoor unit 10 and enters an indoor environment, that is, an air outlet position of the fresh air; here, the air outlet position of the fresh air supply end 112 can be controlled by the spatial position of the fresh air supply end 112. The air supply direction of the fresh air supply end 112 refers to the flow direction of fresh air when the fresh air leaves the indoor unit 10 and enters the indoor environment, i.e. the air supply direction of the fresh air; here, the blowing direction of the fresh air blowing end 112 can be controlled by the attitude angle of the fresh air blowing end 112.

Therefore, the air outlet position and the air supply direction of the fresh air supply end 112 can be reflected by the pose of the fresh air supply end 112; by changing the pose of the fresh air supply end 112, at least one of the air outlet position and the air supply direction of the fresh air supply end 112 can be changed. By changing at least one of the air outlet position and the air supply direction of the fresh air supply end 112, the fresh air can be blown to an indoor target position, and the directional blowing of the fresh air is realized.

Compared with the common fresh air blowing mode of the fresh air conditioner through the air conditioner outlet 114 to the indoor space in the related art, the indoor unit 10 provided by the embodiment of the present application can directionally blow the fresh air to the indoor target position or the specific target without blowing the fresh air to the whole indoor space. Like this, the area that actual need carries out the new trend and blow and the required new trend amount of wind of target location is less, can reduce the temperature influence to indoor zone on the one hand, reduce the fluctuation of indoor temperature to increase indoor user's thermal comfort, on the other hand benefits from less intake and temperature fluctuation, can reduce indoor set 10's work load and energy consumption, reduction noise at work.

In some embodiments, only the air outlet position of the fresh air supply end 112 may be changed without changing the air supply direction of the fresh air supply end 112. Accordingly, the fresh air supply end 112 can have at least one translational degree of freedom. Thus, the fresh air supply end 112 can translate along at least one direction, so that a connecting line between the air outlet position and the target position is parallel to the air supply direction of the fresh air supply end 112; correspondingly, the fresh air blown from the air outlet position reaches the target position along the air supply direction, and the directional fresh air blowing of the specific area is realized. Here, the fresh air supply end 112 may be connected to the casing 11 through a linear motion mechanism to achieve translational motion, and the linear motion mechanism may be in a form such as a linear guide rail mechanism, an electric push rod mechanism, a telescopic cylinder mechanism, and the like, which is not limited in this embodiment of the application.

In other embodiments, only the air blowing direction of the fresh air blowing end 112 may be changed, and the air outlet position of the fresh air blowing end 112 may not be changed. Accordingly, the fresh air supply end 112 may be provided with an air guide structure such as a rotatable air guide plate, so as to change the air supply direction of the fresh air without changing the air outlet position. Thus, the air supply direction of the fresh air supply end 112 can be rotated to face the target position; correspondingly, the fresh air blown from the air outlet position reaches the target position along the air supply direction, and the directional fresh air blowing of the specific area is realized. Here, changing the air supply direction of the fresh air supply end 112 by the air guide structure is regarded as controlling the posture of the fresh air supply end 112.

In still other embodiments, the air outlet position and the air supply direction of the fresh air supply end 112 can be changed simultaneously. Here, the fresh air supply end 112 may have at least one degree of rotational freedom.

In some examples, the fresh air supply end 112 may have at least one rotational degree of freedom, but no translational degree of freedom. Thus, the fresh air supply end 112 can rotate around at least one axis, so that the pose of the fresh air supply end 112 is changed, the air outlet position and the air supply direction of the fresh air supply end are changed, and the connecting line between the air outlet position and the target position is parallel to the air supply direction of the fresh air supply end 112. Correspondingly, the fresh air blown from the air outlet position reaches the target position along the air supply direction, and the directional fresh air blowing of the specific area is realized. Here, the fresh air supply end 112 may be connected to the housing 11 through a rotary motion mechanism, and the rotary motion mechanism may be in the form of a turntable, a hinge structure, a joint bearing, and the like, which is not limited in this embodiment. Illustratively, the fresh air supply end 112 may be disposed on the casing 11 through a joint bearing; accordingly, the fresh air supply end 112 can rotate and swing at any angle, and any rotation purpose can be realized.

In still other examples, the fresh air supply end 112 may have at least one rotational degree of freedom and at least one rotational degree of freedom. Thus, the fresh air supply end 112 can translate along at least one direction and rotate around at least one axis, so that the air outlet position and the air supply direction of the fresh air supply end are changed until a connecting line between the air outlet position and the target position is parallel to the air supply direction of the fresh air supply end 112. Correspondingly, the fresh air blown from the air outlet position reaches the target position along the air supply direction, and the directional fresh air blowing of the specific area is realized. Here, the fresh air blowing end 112 can realize the compound movement of translation and rotation through the compound movement mechanism composed of the linear movement mechanism and the rotary movement mechanism.

In some embodiments, the indoor unit 10 further includes a human body detection device 12 disposed on the casing 11, and the human body detection device 12 is configured to detect a position of a human body. Thus, the position of the user can be obtained according to the information detected by the human body monitoring device. Here, the position of the user may be a spatial position where the user is located as a whole, or may be a spatial position where a specific part of the user's body is located. Accordingly, the indoor unit 10 can provide directional fresh air blowing to the user or a specific part of the user's body, such as the head, to ensure that the air around the user is always fresh.

The specific form of the human body detection device 12 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some examples, the human detection device 12 may include at least one of a camera and a pyroelectric infrared sensor. The camera can acquire image information of an indoor environment, and the controller can determine the position of a user or a specific part of the body of the user according to the acquired image information. Illustratively, the camera may directly perform recognition capture on the head of the user. The pyroelectric infrared sensor can sense the human body and the body contour thereof in an infrared thermal sensing mode, has lower cost and is beneficial to privacy protection of users.

The specific structural form of the fresh air supply end 112 may be determined according to actual needs, and is not limited in the embodiment of the present application. In some embodiments, the fresh air supply end 112 may include a fresh air nozzle. The input end of the fresh air nozzle is communicated with the fresh air inlet 111, and the output end of the fresh air nozzle is configured to be communicated with the indoor environment. The new trend nozzle can be with the injection mode with during the new trend blowout to the indoor environment, the new trend speed and the directionality of blowing are better, air output and direction controllability preferred, can reduce required new trend amount of wind.

In some embodiments, the fresh air supply end 112 may further be provided with a first switch member 13, and the first switch member 13 is configured to control the opening degree of the fresh air supply end 112. Here, the opening degree of the fresh air blowing end 112 refers to the opening degree of the fresh air blowing end 112, such as fully open, fully closed, or half open. When the fresh air supply end 112 is completely opened, the opening degree can reach the maximum value, and the fresh air supply quantity of the fresh air supply end 112 can correspondingly reach the maximum value; when the fresh air supply end 112 is completely closed, the opening degree is zero, no fresh air can pass through the fresh air supply end 112, and the fresh air supply quantity of the fresh air supply end 112 is zero; when the fresh air supply end 112 is in a half-open state, the fresh air supply end 112 is partially opened, so that part of fresh air can be allowed to pass through the fresh air supply end 112, and the fresh air supply quantity of the fresh air supply end 112 is between zero and the maximum value. Therefore, the opening degree of the fresh air supply end 112 where the first switch piece 13 is located can be changed through adjustment of the first switch piece 13, so that the fresh air supply quantity is changed, and different air quantity requirements are met. The structural type of the first switch part 13 may be determined according to actual needs, and various valve parts or special opening and closing mechanisms may be adopted, which is not limited in the embodiment of the present application.

In some embodiments, the indoor unit 10 further includes a fresh air blower, and the fresh air blower is disposed between the fresh air inlet 111 and the fresh air supply end 112. The fresh air fan is used for providing source power required by fresh air circulation, sucking outdoor fresh air from a fresh air inlet 111, and blowing out the fresh air in the indoor unit 10 from a fresh air supply end 112.

In some embodiments, the housing 11 is further provided with an indoor air inlet and an air conditioner outlet 114, which are communicated with each other, and an evaporator is disposed between the indoor air inlet and the air conditioner outlet 114. Indoor air may be drawn into the indoor unit 10 from the indoor air inlet, and then flow through the evaporator to be subjected to temperature/humidity control by the evaporator, and conditioned air may be blown into the indoor environment from the air-conditioning outlet 114. Here, the indoor air inlet and the air outlet 114 may be further provided with an air conditioner fan to provide a source power required for indoor air circulation.

In some examples, the indoor unit 10 further includes an induced air duct 113, and one end of the induced air duct 113 is open between the fresh air inlet 111 and the fresh air supply end 112, and the other end is open between the evaporator and the air conditioner outlet 114. Thus, the air-inducing duct 113 can introduce the air-conditioning air into the space between the fresh air inlet 111 and the fresh air supply end 112 according to the required air volume according to the actual requirement, so as to mix the air-conditioning air with the fresh air, change the temperature of the blown fresh air, and improve the thermal comfort of the user when blowing the fresh air.

Illustratively, the induced air duct 113 is provided with a second switch 14, and the second switch 14 is configured to control the opening degree of the induced air duct 113. Here, the opening degree of the induced air duct 113 refers to the opening degree of the induced air duct 113, such as full open, full close, or half open. When the induced draft air duct 113 is completely opened, the opening degree of the induced draft air duct 113 can reach the maximum value, and the air conditioning air volume of the induced draft air duct 113 can correspondingly reach the maximum value; when the induced draft air duct 113 is completely closed, the opening degree is zero, no air-conditioning air can pass through the induced draft air duct 113, and the air-conditioning air volume of the induced draft air duct 113 is zero; when the induced air duct 113 is in the half-open state, the induced air duct 113 is partially opened, and partial air-conditioned air can be allowed to pass through the induced air duct 113, and the air-conditioned air volume of the induced air duct 113 is between zero and the maximum value. Thus, the opening degree of the induced air duct 113 where the second switch member 14 is located can be changed by adjusting the second switch member 14, so that the air volume of the air-conditioning air for mixing with the fresh air is changed, and the required mixing and adjusting purpose is realized. The structural type of the second switch element 14 may be determined according to actual needs, and various valve elements or special opening and closing mechanisms may be adopted, which is not limited in the embodiment of the present application.

As shown in fig. 2, an embodiment of the present application further provides a fresh air control method for controlling a fresh air blowing process of the indoor unit 10, where the fresh air control method includes S10 to S20.

S10: the head position of a user in an indoor environment is obtained. Here, the head position of the user in the indoor environment can be detected by the human body detecting device 12.

S20: the fresh air supply state of the indoor unit 10 is controlled according to the head position of the user, so that fresh air is supplied to the head of the user. Here, the fresh air blowing state of the indoor unit 10 includes at least one of an air outlet position and an air blowing direction of fresh air. Please refer to the foregoing description for the specific definitions of the air outlet position and the air supply direction of the fresh air, which will not be described herein again.

Compared with the common fresh air blowing mode of the fresh air conditioner through the air conditioner outlet 114 to the indoor space in the related art, the fresh air control method provided by the embodiment of the application can control the fresh air supply state of the indoor unit 10 according to the head position of the user in the indoor environment, so that the indoor unit 10 can directionally blow fresh air to the head of the user, the fresh air blowing to the whole indoor space is not needed, the air around the user can be kept fresh, and the breathing requirement of the user can be met. Like this, the area that actual need carries out the new trend and blow and the required new trend amount of wind of target location is less, can reduce the temperature influence to indoor zone on the one hand, reduce the fluctuation of indoor temperature to increase indoor user's thermal comfort, on the other hand benefits from less intake and temperature fluctuation, can reduce indoor set 10's work load and energy consumption, reduction noise at work.

As shown in FIG. 3, in some embodiments, prior to S20, the fresh air control method may further include S10' S10 ".

S10': it is determined whether a user in an indoor environment is asleep. Here, the current dynamic and static states of the user can be determined by using a human motion state algorithm in the related art. For example, the current state of the user may be determined in combination with the current time and the posture of the user. For example, during the nighttime period between 22:00 of the day and 7:00 of the next day, if the user's inactivity duration exceeds the threshold time, it may be determined that the user is asleep.

S10': in response to determining that the user in the indoor environment is in the sleep state, S20 is performed. In the sleep state, the bedroom is mostly in the closed state, and the carbon dioxide concentration of the indoor environment gradually rises, so that the air quality is continuously reduced. At this time, S20 may be executed to blow fresh air to the head of the user, so as to directly and rapidly improve the air quality around the user, and increase the oxygen content to ensure the respiratory quality and sleep quality of the user.

As shown in fig. 1 and 4, in some embodiments, the indoor unit 10 is provided with at least one fresh air blowing end 112, and S20 may include S21 to S23.

S21: and determining the expected pose of the fresh air supply end 112 according to the head position of the user. The expected pose of the fresh air supply end 112 is the pose expected to be reached by the fresh air supply end 112, and can be calculated according to the head position of the user. Here, the desired pose of the fresh air supply end 112 may include a desired position and a desired attitude angle of the fresh air supply end 112. When the fresh air supply end 112 reaches the expected pose, the air outlet position and the air supply direction of the fresh air supply end 112 both accord with the expectation, and the fresh air can be ensured to be directionally blown to the head of a user.

S22: and determining the motion parameters of the fresh air supply end 112 according to the current pose and the expected pose of the fresh air supply end 112. Here, the current pose of the fresh air supply end 112 may include the current position and the current attitude angle of the fresh air supply end 112, and the motion parameters of the fresh air supply end 112 may include the displacement and the angular displacement required by the fresh air supply end 112. According to the current position and the expected position of the fresh air supply end 112, the displacement required by the fresh air supply end 112 can be determined; the angular displacement required by the fresh air supply end 112 can be determined according to the current attitude angle and the expected attitude angle of the fresh air supply end 112. Thus, the motion parameters of the fresh air supply end 112 can be determined. It should be noted that either one of the displacement and the angular displacement may be zero.

S23: the fresh air supply state of the fresh air supply end 112 is controlled according to the motion parameters of the fresh air supply end 112, so that the fresh air supply end 112 supplies fresh air to the head of a user. According to the displacement of the fresh air supply end 112, the fresh air supply end 112 can be controlled to move horizontally according to the displacement value; according to the angular displacement of the fresh air supply end 112, the fresh air supply end 112 can be controlled to rotate according to the angular displacement. Finally, the air outlet position and the air supply direction of the fresh air supply end 112 are adjusted, so that the fresh air supply end 112 directly blows the fresh air to the head of a user.

Here, each of the fresh air blowing ends 112 can be independently controlled through S21 to S23, so that each of the fresh air blowing ends 112 blows fresh air directionally, and the requirement of blowing fresh air with small air volume and high precision is met.

As shown in fig. 2, in some embodiments, the fresh air control method may further include S30.

S30: the air-conditioning air supply state of the indoor unit 10 is controlled according to the head position of the user so that the air-conditioning air is blown away from the head position of the user, and the air-conditioning air supply state includes at least one of the air-out position and the air supply direction of the air-conditioning air.

The air outlet position of the air outlet 114 refers to a position where the conditioned air exits from the indoor unit 10 and enters the indoor environment, i.e., an air outlet position of the conditioned air; here, the air outlet position of the outlet 114 may be controlled by the spatial position of the outlet 114. The air supply direction of the air-conditioning outlet 114 refers to a flow direction of the air-conditioning air when the air-conditioning air exits from the indoor unit 10 and enters the indoor environment, that is, the air supply direction of the air-conditioning air; here, the blowing direction of the outlet 114 may be controlled by the attitude angle of the outlet 114.

Thus, the air outlet position and the air supply direction of the air conditioning air can be reflected by the pose of the air conditioning air outlet 114; by changing the posture of the air outlet 114, at least one of the air outlet position and the air supply direction of the air conditioning air can be changed. By changing at least one of the air outlet position and the air supply direction of the air-conditioning outlet 114, the air-conditioning air can be blown away from the head of the user, thereby avoiding the impact or discomfort of the user caused by directly blowing the cold air and the hot air, and improving the comfort of the user. For example, the air outlet 114 may be provided with a wind guiding structure such as a rotatable wind guiding plate, so as to change the air supplying direction of the air-conditioned air without changing the wind outlet position, and avoid the head position of the user.

It should be noted that, in the embodiment of the present application, the execution order of S20 and S30 is not limited, and the order of S20 and S30 may be determined according to actual needs.
