The air conditioner indoor unit with the rotary heater structure adopts a spliced rotatable structure, and can rotate the windward side of the heater to be as perpendicular to the airflow direction as possible under heating operation, so that the heat exchange area of a heat exchanger can be effectively increased, the flow loss of airflow is reduced, incoming air and the heater can be fully exchanged, the heat exchange (especially heating) effect of the air conditioner indoor unit is improved, and the technical problem that the heat exchange effect of the existing structural heater is not ideal is solved;
Meanwhile, through the air conditioner indoor unit with the rotary heater structure, the heater can be rotated under the refrigeration condition, so that the heater is parallel to the incoming flow direction of air flow as much as possible, the incoming flow resistance is reduced, the turbulence intensity of the air flow passing through the heater is reduced, the noise of the fan is reduced, the performance of the fan is improved, the power consumption and the noise of the fan are improved, and the technical problems that the turbulence intensity of the air flow at the heater is high and the noise of the air conditioner is high under the existing non-heating condition are effectively solved.
Preferably, the number of the heating structural units is two, namely a first heating unit 61 and a second heating unit 62, and the first heating unit 61 and/or the second heating unit 62 can rotate to form a connected or separated position relationship between the two. The heating structure units are arranged in two modes which are the preferred number and the structural form of the heating structure units, and the air flow passing through the heater part can be controlled to be acted by at least one of the first heating unit and the second heating unit to form a connected or separated position relation between the first heating unit and the second heating unit, so that the channel passing through the heater part can be closed or opened.
Preferably, the first heating unit 61 has a substantially prismatic structure, and one end thereof is connected to the inner wall surface of the housing 1 through a first rotation connection mechanism 71; and/or the second heating unit 62 is also substantially prismatic in structure, and one end thereof is connected to the inner wall surface of the housing 1 by a second rotational connection mechanism 72. The first and/or second heating units are processed and arranged into a structure form of a general prism, which is a preferable shape and structure form, and one ends of the two units are respectively connected to the inner wall surface of the shell through a form of a rotary connecting mechanism, so that at least one of the two heating units can effectively rotate around the corresponding rotary connecting mechanism, and the aim and effect of effectively controlling the airflow path can be achieved.
Preferably, the first rotary connecting mechanism 71 and/or the second rotary connecting mechanism 72 are pin rotary structures. This is a preferred type and form of construction of the first and second rotary connection.
Preferably, the first heating unit 61 is rotatable about the first rotation connection 71 within a range of 90 degrees between a direction parallel to the incoming air flow and a direction perpendicular to the incoming air flow; and/or the second heating unit 62 may be rotated about the second rotation connection mechanism 72 within a range of 90 degrees between a direction parallel to the incoming air flow and a direction perpendicular to the incoming air flow. The first heating unit and the second heating unit rotate within a 90-degree range between the direction parallel to the incoming airflow and the direction perpendicular to the incoming airflow, so that the two heating units can effectively adjust between the vertical blocking of the airflow and the complete unblocking of the airflow, the effect of adjusting and controlling the incoming airflow within the whole range is effectively achieved, the rotation range is small, namely the rotation range is 90 degrees, and the useless rotation range is reduced.
As shown in fig. 1, when the air conditioning indoor unit is in heating operation, the first heating unit 61 and the second heating unit 62 are preferably rotated in opposite directions to each other to a position where they are in contact with each other. When the indoor air conditioner is used for heating, the heat exchange efficiency is required to be improved, and the heating intensity is increased, so that the first heating unit and the second heating unit are rotated to the connecting position of the first heating unit and the second heating unit in the opposite directions, and the first heating unit and the second heating unit can be rotated to the connecting position, so that the windward surfaces of the first heating unit and the second heating unit are perpendicular or approximately perpendicular to the incoming flow direction of the air flow, the blocking degree of the air flow is increased, the contact area between the first heating unit and the air flow is increased, the heat exchange intensity is enhanced, and the heat exchange efficiency is improved.
Preferably, when the first heating unit 61 and the second heating unit 62 are connected, the windward sides of the first heating unit and the second heating unit are perpendicular to the incoming airflow direction. The two heating units are preferably rotated to stop positions, and the blocking effect on the air flow can be effectively realized to the greatest extent by rotating the two heating units to the mode that the windward sides of the two heating units are respectively perpendicular to the incoming flow direction of the air flow, so that the heat exchange area is increased to the greatest extent, and the heat exchange efficiency is improved.
As shown in fig. 2, when the air conditioning indoor unit is in a cooling operation, the first heating unit 61 and the second heating unit 62 are preferably rotated in opposite directions to each other to a position where they are separated from each other. When the indoor air conditioner is in refrigerating operation, the incoming flow does not need to be heated at the moment, so that the first heating unit and the second heating unit are rotated to the positions where the first heating unit and the second heating unit are separated from each other in opposite directions, air flow can be contained to pass through the first heating unit and the second heating unit, air flow resistance is reduced, turbulence intensity is reduced, and accordingly fan noise is reduced, and the working performance of a fan and an air conditioner is improved.
Preferably, the first heating unit 61 and the second heating unit 62 are rotated to separate positions where windward sides of the two are parallel to the incoming direction of the air flow, respectively. This is the preferred separation position of the two heating units, which enables the heater to be as parallel as possible to the incoming flow direction of the air flow, thereby minimizing incoming flow resistance, reducing the turbulence intensity of the air flow inside through the heater, minimizing fan noise and improving fan performance.
The invention also provides an air conditioner which comprises the air conditioner indoor unit with the rotary heater structure. Through the air conditioner indoor unit with the rotary heater structure, the windward side of the heater can be rotated to be as perpendicular to the airflow direction as possible under the heating operation, so that the heat exchange area of the heat exchanger can be effectively increased, the flow loss of airflow is reduced, the incoming air and the heater can be fully exchanged, the heat exchange (especially heating) effect of the air conditioner indoor unit is improved, and the technical problem that the heat exchange effect of the existing structural heater is not ideal is solved;
Meanwhile, the heater can be rotated under the refrigeration condition, so that the heater is parallel to the incoming flow direction of the air flow as much as possible, the incoming flow resistance is reduced, the turbulence intensity of the air flow passing through the heater is reduced, the noise of the fan is reduced, the performance of the fan is improved, the power consumption and the noise of the fan are improved, and the technical problems that the turbulence intensity of the air flow at the heater is high and the noise of the air conditioner is high under the existing non-heating condition are effectively solved.
