Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] In some related technologies, ducted air conditioners use horizontal lateral airflow. In heating mode, the hot air is blown out horizontally. Because hot air has a lower density, it rises, and since people's heat needs are at a height of 1.6 meters or below, the hot air is difficult to deliver to the area where people are active, resulting in poor heating performance. In other related technologies, a downward airflow method is used. In cooling mode, cold air is blown directly onto people, resulting in poor comfort.

[0003] Existing technologies typically employ reverse fan rotation to achieve reverse airflow, enabling the ducted air conditioner to simultaneously deliver horizontal and vertical air. However, the airflow is relatively small when the fan rotates in reverse. If the ducted air conditioner is cooling when the fan is rotating forward, it needs to rotate in reverse when heating, resulting in poor heating capacity. Similarly, if the ducted air conditioner is heating when the fan is rotating forward, it needs to rotate in reverse when cooling, resulting in poor cooling capacity. Both solutions severely impact the heat exchange efficiency of the ducted air conditioner. Utility Model Content

[0004] To address the technical problem that fan reversal in existing technologies cannot guarantee heat exchange efficiency, an air conditioning indoor unit and air conditioner are provided that utilize a movable volute and baffles to adjust the air supply direction without adjusting the fan rotation direction to ensure heat exchange efficiency.

[0005] An indoor unit for an air conditioner includes:

[0006] The housing includes a first return air inlet and a second return air inlet;

[0007] A fixed volute is disposed within the housing. The fixed volute includes a first air outlet and a second air outlet, and an air inlet is provided on the fixed volute.

[0008] A movable volute is movably disposed within the fixed volute, and the movable volute is capable of shielding the first air outlet and avoiding the second air outlet, or avoiding the first air outlet and shielding the second air outlet.

[0009] A baffle is connected to the movable volute. The baffle is connected to the movable volute and can isolate the first return air inlet and the air inlet or isolate the second return air inlet and the air inlet.

[0010] A sealing structure is provided on the housing. When the baffle isolates the first return air inlet and the air inlet or the second return air inlet and the air inlet, the baffle and the sealing structure are sealed together.

[0011] The baffle has two opposing edges. When the baffle is sealed with the sealing structure, one edge is sealed with one sealing structure and the other edge is sealed with the other sealing structure.

[0012] A raised structure is provided at the edge. When the baffle and the sealing structure are sealed together, the raised structure abuts against the corresponding sealing structure.

[0013] The sealing structure includes a first sealing element, a second sealing element, and a third sealing element distributed sequentially around the rotation axis of the baffle. The two opposing edges include a first edge and a second edge. When the baffle isolates the second return air inlet and the air inlet, the first edge and the first sealing element are sealed together, and the second edge and the second sealing element are sealed together. When the baffle isolates the first return air inlet and the air inlet, the first edge and the second sealing element are sealed together, and the second edge and the third sealing element are sealed together.

[0014] The sealing structure includes a support member and a flexible member. The support member is fixedly disposed on the housing, and the flexible member is disposed on the support member. When the baffle is sealed with the sealing structure, the baffle can compress the flexible member.

[0015] When the movable volute is in a state of blocking the first air outlet or blocking the second air outlet, the movable volute and a portion of the fixed volute form a complete fixed volute-like structure.

[0016] The movable volute and the baffle together constitute a movable component, which has a first working state and a second working state:

[0017] When the movable component is in the first working state, the movable volute shields the second air outlet, and the baffle isolates the second return air outlet and the air inlet, so that the airflow enters the fixed volute through the first return air outlet and flows out from the first air outlet.

[0018] When the movable component is in the second working state, the movable volute shields the first air outlet, and the baffle isolates the first return air outlet and the air inlet, so that the airflow enters the fixed volute through the second return air outlet and flows out from the second air outlet.

[0019] The first return air vent is located on the bottom wall of the housing, and the second return air vent is located on the side wall of the housing; the first air outlet is connected to the outside of the housing via the side wall of the housing, and the second air outlet is connected to the outside of the housing via the bottom wall of the housing.

[0020] The indoor unit of the air conditioner has a cooling mode and a heating mode. When the indoor unit of the air conditioner is in the cooling mode, the moving part is in the first working state; when the indoor unit of the air conditioner is in the heating mode, the moving part is in the second working state.

[0021] An air conditioner, comprising the above-mentioned indoor unit.

[0022] The air conditioner indoor unit and air conditioner provided by this utility model can adjust the air inlet and outlet directions of the indoor unit by setting a movable volute and a baffle. The return air inlet and outlet can be selected as needed, and the return air and outlet positions can be changed to achieve bottom return air and side air outlet, so as to achieve cold air blowing horizontally and avoid the discomfort caused by direct cold air blowing; it can also achieve side return air and bottom air outlet, so as to achieve hot air blowing downward and improve the heating effect. Moreover, by using a sealing structure in cooperation with the baffle, the baffle can ensure the isolation effect of the first return air inlet and the air inlet or the second return air inlet and the air inlet, further ensuring the reliability of the air conditioner indoor unit and the heat exchange effect.

[0039] Existing technologies typically employ reverse fan rotation to achieve reverse airflow, enabling the ducted air conditioner to simultaneously deliver horizontal and vertical air. However, the airflow is relatively small when the fan rotates in reverse. If the unit is cooling when the fan is rotating forward, it needs to rotate in reverse to heat, resulting in poor heating capacity. Similarly, if the unit is heating when the fan is rotating forward, it needs to rotate in reverse to cool, resulting in poor cooling capacity. Both solutions severely impact the heat exchange efficiency of the unit.

[0040] Therefore, this application provides a method such as Figures 1 to 9The air conditioner indoor unit shown includes: a housing 1, including a first return air inlet 11 and a second return air inlet 12; a fixed volute 2, disposed within the housing 1, the fixed volute 2 including a first air outlet and a second air outlet, and an air inlet provided on the fixed volute 2; a movable volute 3, movably disposed within the fixed volute 2, the movable volute 3 capable of shielding the first air outlet and avoiding the second air outlet, or avoiding the first air outlet and shielding the second air outlet; a baffle 4, connected to the movable volute 3, the baffle 4 capable of isolating the first return air inlet 11 and the air inlet, or isolating the second return air inlet 12 and the air inlet; and a sealing structure, disposed on the housing 1, wherein when the baffle 4 isolates the first return air inlet 11 and the air inlet, or isolates the second return air inlet 12 and the air inlet, the baffle 4 and the sealing structure are sealed together. By setting the movable volute 3 and baffle 4, the air inlet and outlet directions of the indoor unit of the air conditioner can be adjusted. Thus, the return air vent and outlet can be selected as needed, and the return air and outlet positions can be changed. It can achieve bottom return air and side air outlet, so that the cold air blows horizontally and avoids the discomfort caused by direct cold air blowing. It can also achieve side return air and bottom air outlet, so that the hot air blows downward and improves the heating effect. Moreover, by using the sealing structure in conjunction with the baffle 4, the isolation effect of the baffle 4 on the first return air vent 11 and the air inlet or the isolation effect on the second return air vent 12 and the air inlet can be guaranteed, further ensuring the reliability of the indoor unit of the air conditioner and the heat exchange effect.

[0041] The baffle 4 has two opposing edges. When the baffle 4 is sealed with the sealing structure, one edge is sealed with one sealing structure and the other edge is sealed with another sealing structure. By cooperating with the edges of the sealing structure, a reliable seal can be achieved between the baffle 4 and the sealing structure, and the movement of the baffle 4 can also be guaranteed to be reliable. In particular, the sealing structure set on the movement path of the baffle 4 can avoid the area between the two edges of the baffle 4 and can also be sealed with the edges.

[0042] Furthermore, to ensure the sealing effect between the edge and the sealing structure, a protruding structure 5 is provided at the edge. When the baffle 4 and the sealing structure are sealed together, the protruding structure 5 abuts against the corresponding sealing structure. The protruding structure 5 increases the thickness of the baffle 4 at the edge, so that the sealing structure on the movement path of the baffle 4 can reliably avoid the baffle 4 to ensure the reliable movement of the baffle 4. At the same time, it allows the sealing structure to cooperate with the corresponding protruding structure 5 to ensure the sealing effect.

[0043] Specifically, the fixed volute 2 is cylindrical, and the movable volute 3 and the baffle 4 both rotate about the axis of the fixed volute 2. The sealing structure includes a first sealing element 61, a second sealing element 62, and a third sealing element 63, which are sequentially distributed about the axis of rotation of the baffle 4. The two opposing edges include a first edge 41 and a second edge 42. When the baffle 4 isolates the second return air inlet 12 and the air inlet, the first edge 41 seals with the first sealing element 61, and the second edge 42 seals with the second sealing element 62. When the baffle 4 isolates the first return air inlet 11 and the air inlet, the first edge 41 seals with the second sealing element 62, and the second edge 42 seals with the third sealing element 63. That is, the second seal 62 is located on the movement path of the baffle 4, and the second seal 62 is located between the first edge 41 and the second edge 42. The first edge 41 can move between the first seal 61 and the second seal 62, and the second edge 42 can move between the second seal 62 and the third seal 63. The positions of the first seal 61, the second seal 62, and the third seal 63 are set according to the rotation range of the baffle 4. Preferably, both the first edge 41 and the second edge 42 are provided with protruding structures 5. The protruding structures 5 increase the height of the first edge 41 and the second edge 42, so that during the rotation of the baffle 4, the baffle 4 between the first edge 41 and the second edge 42 will not interfere with the second seal 62. However, the protruding structure 5 on the first edge 41 can reliably abut and cooperate with the second seal 62, and the protruding structure 5 on the second edge 42 can also reliably abut and cooperate with the second seal 62, ensuring the sealing effect between the baffle 4 and the housing 1.

[0044] like Figures 4 to 6 as well as Figure 8As shown, the sealing structure includes a support member 71 and a flexible member 72. The support member 71 is fixedly mounted on the housing 1, and the flexible member 72 is mounted on the support member 71. When the baffle 4 is in sealing cooperation with the sealing structure, the baffle 4 can compress the flexible member 72. The support member 71 forms a structure close to the baffle 4 inside the housing 1, facilitating the structural design of the housing 1. Simultaneously, the flexible member 72 abuts against the baffle 4, creating flexible contact and avoiding direct collision between the baffle 4 and the support member 71, thus preventing noise. The deformation of the flexible member 72 further enhances the sealing effect between the sealing structure and the baffle 4. Furthermore, the flexible deformation of the flexible member 72 increases the movable range of the baffle 4, controlling potential displacement errors during movement. Compared to directly using the limiting function of the support member 71, this effectively increases the adjustment margin, further ensuring the reliability of the baffle 4's movement. Optionally, the support member 71 may be a sheet metal part, and the flexible member 72 may be a sponge.

[0045] Furthermore, the support plate 71 is L-shaped, and the L-shape includes a connecting section and a mating section. The mating section is connected to the housing 1 through the connecting section, and a flexible element 72 is provided on the side wall of the mating section facing the baffle 4. By increasing the size of the flexible element 72 by utilizing the size of the mating section, the protruding structure 5 can cooperate with the flexible elements 72 at different positions on the mating section to ensure the sealing effect between the baffle 4 and the sealing structure.

[0046] When the movable volute 3 is in a state of blocking the first air outlet or blocking the second air outlet, the movable volute 3 and a portion of the fixed volute 2 form a complete fixed volute 2-like structure. The movable volute 3 can form a complete fixed volute 2-like structure with a portion of the fixed volute 2 when the first air outlet is blocked, thus enabling the second air outlet to operate; conversely, it can form a complete fixed volute 2-like structure with a portion of the fixed volute 2 when the second air outlet is blocked, thus enabling the first air outlet to operate. Therefore, it allows for adjustment of the air outlet position without affecting the fixed volute 2-like structure, achieving normal return and outlet airflow.

[0047] The movable volute 3 and the baffle 4 together constitute a movable component, which has a first working state and a second working state: When the movable component is in the first working state, the movable volute 3 blocks the second air outlet, and the baffle 4 isolates the second return air inlet 12 and the air inlet, so that the airflow enters the fixed volute 2 through the first return air inlet 11 and flows out from the first air outlet; When the movable component is in the second working state, the movable volute 3 blocks the first air outlet, and the baffle 4 isolates the first return air inlet 11 and the air inlet, so that the airflow enters the fixed volute 2 through the second return air inlet 12 and flows out from the second air outlet. At this time, the movable volute 3 and the baffle 4 move synchronously to ensure reliable control of the air inlet and outlet directions of the fan structure formed by the movable volute 3 and the fixed volute 2, thereby ensuring control of the air supply and return directions of the indoor unit of the air conditioner.

[0048] The first return air vent 11 is located on the bottom wall of the housing 1, and the second return air vent 12 is located on the side wall of the housing 1. When the baffle 4 separates the second return air vent 12 from the air inlet, the indoor unit of the air conditioner can return air from the bottom of the housing 1 through the first return air vent 11. When the baffle 4 separates the first return air vent 11 from the air inlet, the indoor unit of the air conditioner can return air from the side of the housing 1 through the second return air vent 12.

[0049] The first air outlet is connected to the outside of the housing 1 through the side wall of the housing 1, and the second air outlet is connected to the outside of the housing 1 through the bottom wall of the housing 1. That is, the air from the first air outlet can blow out to the side of the housing 1, and the air from the second air outlet can blow out to the bottom of the housing 1, thereby realizing the switching of side air supply or downward air supply of the indoor unit of the air conditioner.

[0050] The indoor unit of the air conditioner has a cooling mode and a heating mode. When the indoor unit is in the cooling mode, the moving parts are in the first working state. At this time, the indoor air enters the fixed volute 2 through the first return air inlet 11 located at the bottom, and then is blown out through the first air outlet under the drive of the fan blades in the fixed volute 2. Finally, it is blown out through the side wall of the housing 1, realizing bottom return air and side air outlet, and realizing flat blowing of cold air to avoid the discomfort caused by direct blowing of cold air. When the indoor unit is in the heating mode, the moving parts are in the second working state. At this time, the indoor air enters the fixed volute 2 through the second return air inlet 12 located on the side wall, and then is blown out through the second air outlet under the drive of the fan blades in the fixed volute 2. Finally, it is blown out through the bottom wall of the housing 1, realizing side return air and bottom air outlet, and realizing downward blowing of hot air to improve the heating effect.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
