DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] First embodiment

[0028] See also Figure 1 and Figure 2 This embodiment provides an indoor unit 100. The indoor unit 100 provided in this embodiment can enhance the comfort of users when using the air conditioner.

[0029] Usually, the indoor unit 100 is installed indoors, and is mainly used to re-introduce the air after heat exchange into the room, so that the indoor air reaches a more comfortable temperature range. At present, the existing indoor unit 100 generally discharges air from the front. If it is in summer, the air after heat exchange by the evaporator is cold air. If the cold air blows directly to the user's body surface for a long time, it is easy to cause human discomfort, easy to cause colds and other diseases, which is not conducive to the user's health and leads to a poor user's comfort experience. The indoor unit 100 provided in this embodiment can improve the above problems.

[0030] It should be noted that the indoor unit 100 mentioned in the present embodiment mainly refers to an on-hook unit, and the fresh air refers to the air after heat exchange in the indoor unit 100.

[0031] In this embodiment, the indoor unit 100 includes a middle frame 110, an end cover 120 and a front panel 130. The front panel 130 is installed on the middle frame 110. The end cover 120 is installed on at least one side of the middle frame 110 and forms an air inlet channel 140 with the middle frame 110. A first air outlet 122 is provided on the end cover 120. The first air outlet 122 is used to introduce the fresh air entering the air inlet channel 140 into the room.

[0032] In this embodiment, for the convenience of description, the surface of the middle frame 110 on which the front panel 130 is installed is defined as the front, the side of the surface of one side of the middle frame 110 on which the end cover 120 is installed is defined as the side, the surface above the middle frame 110 is defined as the top, and the surface on which the rear panel 170 is installed is defined as the back. The end cover 120 is installed on the side of the middle frame 110 and forms an air inlet channel 140 with the middle frame 110. The fresh air entering the air inlet channel 140 can enter the room through the first air outlet 122. Since the first air outlet 122 is installed on the end cover 120 arranged on the side, when in the cooling mode, the fresh air temperature is low, and the side air outlet can minimize the fresh air from blowing directly on the user, thereby improving the comfort of using the air conditioner.

[0033] It should be noted that, in the present embodiment, there are two end covers 120, which are respectively arranged on the two sides of the middle frame 110, so that air can be discharged from the two sides of the indoor unit 100, so that the fresh air blown out from both sides forms a circulating convection, and the air discharge from the two sides can increase the angle of the fresh air outlet, improve the coverage of the fresh air, and increase comfort.

[0034] See also Figure 3 In this embodiment, a connection port 112 is provided on the middle frame 110 , and the air inlet channel 140 is connected to the internal cavity of the middle frame 110 through the connection port 112 , so that the fresh air in the internal cavity of the middle frame 110 enters the air inlet channel 140 from the connection port 112 .

[0035] When the indoor air enters the indoor unit 100 for heat exchange, it is mainly concentrated in the internal cavity at the lower part of the middle frame 110. The connection port 112 is arranged below the middle frame 110. The fresh air can enter the fresh air channel from the connection port 112 and then enter the room through the first air outlet 122.

[0036] In this embodiment, the connection port 112 and the first air outlet 122 are staggered.

[0037] Since the first air outlet 122 is staggered with the connection port 112, after the fresh air in the inner cavity of the middle frame 110 enters the air inlet channel 140 through the connection port 112, the fresh air cannot be blown out directly from the first air outlet 122, and the air inlet channel 140 can play a certain buffering role and reduce the wind speed of the fresh air. The wind speed of the fresh air blown out from the first air outlet 122 is relatively low, and even if a user stands on the side of the indoor unit 100, the fresh air felt by the user is relatively gentle due to the low wind speed of the fresh air blown out from the first air outlet 122, which improves the user's experience.

[0038] In this embodiment, the end cover 120 includes an end plate 124 and a connecting plate 126, one side of the connecting plate 126 is connected to the end plate 124, and the side of the connecting plate 126 away from the end plate 124 is connected to the middle frame 110, and the connecting plate 126, the end plate 124 and the middle frame 110 form an air inlet channel 140.

[0039] In this embodiment, there are multiple connecting plates 126, which are connected end to end in sequence and connected to the edge of the end plate 124, so that the end cover 120 is an end cover structure. It can be considered that the end plate 124 is spaced apart from the side of the middle frame 110 and is parallel to each other.

[0040] In this embodiment, the first air outlet 122 is disposed on the end plate 124. This is equivalent to the first air outlet 122 being disposed on the side of the middle frame 110. The fresh air blown out from the first air outlet 122 is discharged from the side of the middle frame 110, which can prevent the cold air from blowing directly downward in the cooling mode, thereby improving the user experience.

[0041] Among them, there are multiple first air outlets 122, and the multiple first air outlets 122 are arranged on the tube plate from top to bottom in sequence. When the fresh air enters the air inlet channel 140, it enters the room from the multiple first air outlets 122. The multiple first air outlets 122 can increase the air outlet from the side of the indoor unit 100, so that the indoor air can reach a more comfortable temperature more quickly.

[0042] See also Figure 4 and Figure 5 In this embodiment, the indoor unit 100 also includes an air guide door 150 and a sliding door 160. The sliding door 160 is slidably connected to the front panel 130, and the air guide door 150 is rotatably connected to the middle frame 110. When the air guide door 150 is opened to the first position, the sliding door 160 can slide relative to the front panel 130 until it contacts the air guide door 150, so that the fresh air in the middle frame 110 can enter the air inlet channel 140.

[0043] See also Figure 6 The air guide door 150 is arranged below the middle frame 110. When the indoor unit 100 is in cooling mode or heating mode, the air guide door 150 is opened, and the fresh air inside the middle frame 110 can enter the room from the air guide door 150. If it is in cooling mode, the fresh air has a lower temperature, and the cold air may blow directly downward onto the user. At this time, the sliding door 160 can be slid down to contact with the air guide door 150, closing the outlet below, and the fresh air is pressed from the front to enter the air inlet channel 140 from the connecting port 112, and blown out from the first air outlet 122.

[0044] It is easy to understand that when the indoor unit 100 receives a cooling command, the indoor unit 100 is in a cooling mode, and when the indoor unit 100 receives a heating command, the indoor unit 100 is in a heating mode.

[0045] When the indoor unit 100 receives a cooling command or a heating command, the sliding door 160 slides relative to the front panel 130 to the lower limit position. When the indoor unit 100 receives a cooling command, it slides to the lower limit position to contact the air guide door 150, closing the outlet on the front of the indoor unit 100.

[0046] That is, if the indoor unit 100 receives a cooling command, the air guide door 150 automatically moves to the first position, and the sliding door 160 slides to the lower limit position relative to the front panel 130 .

[0047] In order to control the position of the air guide door 150, a first driver is provided at the air guide door 150 and is connected to the air guide door 150. The first driver may be a motor, and the rotation angle of the air guide door 150 relative to the middle frame 110 is controlled by controlling the stroke of the motor. Similarly, in order to control the sliding door 160, a second driver is provided at the front and is connected to the sliding door 160. The second driver drives the sliding door 160 to slide relative to the front panel 130 to the lower limit position.

[0048] In this embodiment, a third air outlet 162 is disposed on the sliding door 160 , and the third air outlet 162 can be communicated with the inner cavity of the middle frame 110 .

[0049] In this embodiment, when the sliding door 160 slides and contacts the air guide door 150, the air guide door 150 and the sliding door 160 cooperate to close the front outlet, and the third air outlet 162 is connected to the internal cavity of the middle frame 110, so that part of the fresh air can be blown out through the third air outlet 162. Since the sliding door 160 is disposed on the front of the middle frame 110, the fresh air blown out from the third air outlet 162 is blown toward the front and will not be blown directly onto the user.

[0050] Among them, the aperture of the third air outlet 162 is relatively small, and when the fresh air in the middle frame 110 is blown out from the third air outlet 162, the wind speed is relatively low, the wind feeling is relatively small, and the direct blowing of cold wind from the front is reduced, and the wind outlet effect with zero wind feeling can be achieved.

[0051] In this embodiment, there are multiple third air outlets 162, and the multiple third air outlets 162 are arranged in a matrix. The multiple third air outlets 162 arranged in a matrix are arranged in a square shape, which improves the aesthetic appearance of the entire indoor unit 100.

[0052] It should be noted that, in the present embodiment, the plurality of third air outlets 162 are arranged in a matrix, but are not limited thereto. In other embodiments of the present invention, the third air outlets 162 may be arranged in a trapezoidal, circular or other manners. Schemes equivalent to the present embodiment and capable of achieving the effects of the present embodiment are all within the protection scope of the present invention.

[0053] Furthermore, the connection port 112 may be in a circular, rectangular, or diamond shape.

[0054] In this embodiment, the indoor unit 100 further includes a rear panel 170 disposed opposite to the front panel 130 , and the first air outlet 122 is disposed close to the rear panel 170 .

[0055] In this embodiment, the first air outlet 122 is arranged close to the rear panel 170, and the fresh air blown out from the first air outlet 122 is closer to the rear panel 170, that is, the farther the first air outlet 122 is from the third air outlet 162 on the sliding door 160, the larger the air outlet range of the entire indoor unit 100 can be while achieving three-sided air supply, forming a circulating convection and increasing comfort.

[0056] See also Figure 7 In the present embodiment, when the air guide door 150 is opened to the second position, the sliding door 160 slides relative to the front panel 130 , and a second air outlet 164 communicating with the internal cavity of the middle frame 110 is formed between the air guide door 150 and the sliding door 160 .

[0057] In this embodiment, the second position is below the first position. When the indoor unit 100 receives a heating command, the air guide door 150 opens to the second position, and the sliding door 160 also slides to the lower extreme position. At this time, the sliding door 160 is still some distance away from the air guide door 150 and cannot contact the air guide door 150. The gap between the air guide door 150 and the sliding door 160 forms a second air outlet 164. In the heating mode, the fresh air blown out is hot air. The position of the second air outlet 164 is close to the bottom, so that the hot air can fall to the ground faster, thereby improving the heating comfort.

[0058] In this embodiment, a receiving groove 132 is provided on the front panel 130, and the receiving groove 132 is used to install the sliding door 160. When the sliding door 160 is installed in the receiving groove 132, the front of the sliding door 160 and the front of the front panel 130 are just in the same plane, which improves the flatness of the surface of the entire indoor unit 100 and improves the aesthetics of the indoor unit 100.

[0059] The working principle of the indoor unit 100 provided in this embodiment is as follows: in this embodiment, when the indoor unit 100 receives a cooling command, the first driver controls the air guide door 150 to move to the first position, and the second driver controls the sliding door 160 to slide to the extreme position below the front panel 130. The air guide door 150 and the sliding door 160 abut against each other, closing the air outlet on the front side of the indoor unit 100. The fresh air in the middle frame 110 is subjected to the pressure from the front side, enters the air inlet channel 140 from the connecting port 112, and is blown into the room from the first air outlet 122, and part of the fresh air is blown out from the front side of the third air outlet 162.

[0060] When the indoor unit 100 receives a heating command, the first driver controls the air guide door 150 to run to the second position, and the second driver controls the sliding door 160 to slide to the lower extreme position. The air guide door 150 and the sliding door 160 form a lower second air outlet 164, and most of the hot air is blown out from the second air outlet 164.

[0061] In summary, in the indoor unit 100 provided in this embodiment, the end cover 120 is installed on the side of the middle frame 110 and forms an air inlet channel 140 with the middle frame 110, and the fresh air entering the air inlet channel 140 can enter the room through the first air outlet 122. Since the first air outlet 122 is installed on the end cover 120 arranged on the side, when in cooling mode, the temperature of the fresh air is relatively low, and the side air outlet can minimize the fresh air from blowing directly on the user, thereby improving the comfort of the user when using the air conditioner.
