[0044] Figure 1 is a schematic diagram of an air conditioner indoor unit system 10 according to an embodiment of the present utility model; Figure 2 yes Figure 1 A schematic diagram of a vertical air conditioner indoor unit 20 of the air conditioner indoor unit system 10 is shown; Figure 3 yes Figure 2 The diagram is a partial enlarged schematic diagram of part A of the indoor unit 20 of the vertical air conditioner.

[0045] refer to Figure 1 and Figure 2 As shown, the present invention provides a vertical air conditioner indoor unit 20 and an air conditioner indoor unit system 10. The vertical air conditioner indoor unit 20 includes a casing 21 and a front panel 22.

[0046] refer to Figure 3 As shown, a slide groove 21A is formed on each of the two lateral walls of the housing 21 in the front-to-back direction; the slide groove 21A is used to limit the forward and backward sliding of the vertical air conditioner indoor unit 20 along the preset slide rails 14. A front panel 22 is disposed on the front side of the housing 21; and the front panel 22 is provided with an air inlet 22A and an air outlet 22B.

[0047] Figure 2 and Figure 3 Only the slide groove 21A on one side wall of the housing 21 is shown. It is understood that a slide groove 21A is also provided on the other side wall of the housing 21 (not shown). The two slide grooves 21A each extend in the front-to-back direction, thereby cooperating with the preset slide rails 14 to restrict the vertical air conditioner indoor unit 20 to slide only in the front-to-back direction.

[0048] The air inlet 22A and air outlet 22B of the vertical air conditioner indoor unit 20 of this embodiment are both located on the front panel 22, allowing air to flow in and out through the opening of the cabinet 12. This makes it suitable for installation in a built-in environment within the cabinet 12, unlike other existing vertical air conditioner indoor units with rear-side air intake, which can experience poor air flow when installed within the cabinet. Due to the relatively large size and weight of the vertical air conditioner indoor unit 20, uneven thrust may occur during installation into the cabinet 12, causing the vertical air conditioner indoor unit 20 to collide with the cabinet 12 or even become stuck. The vertical air conditioner indoor unit 20 of this embodiment also has slide grooves 21A on both lateral walls of the housing 21. The slide grooves 21A cooperate with slide rails 14 pre-set on the inner wall of the cabinet 12 to guide the vertical air conditioner indoor unit 20 into the cabinet 12 for installation.

[0049] In some optional embodiments, reference Figure 2 and Figure 3 As shown, the rear end of each slide groove 21A extends to the rear end of the housing 21 , and the front end of each slide groove 21A is spaced apart from the front end of the housing 21 .

[0050] In this embodiment, the rear end of the chute 21A extends to the rear end of the housing 21, and the slide rail 14 can extend into the chute 21A from the rear to the front. At the same time, the front end of the chute 21A is spaced from the front end of the housing 21, so that the front ends of the chute 21A and the slide rail 14 do not protrude from the front end of the housing 21.

[0051] In some optional embodiments, the housing 21 is provided with a fixing hole 21B at a position opposite the front end of the slide groove 21A, and each fixing hole 21B connects the front end of the slide groove 21A and the front end of the housing 21 along the front-to-back direction; the fixing hole 21B is used to pass through a fixing screw to fix the housing 21 to the slide rail 14.

[0052] refer to Figure 3 As shown, in order to secure the vertical air conditioner indoor unit 20 after it is in place, this embodiment further defines a fixing hole 21B in the housing 21 at a position directly opposite the front end of the slide groove 21A. The fixing hole 21B connects the front end of the slide groove 21A with the front end of the housing 21 in the front-to-back direction, so that the vertical air conditioner indoor unit 20 is directly opposite the slide rail 14 after it is in place. The installer can insert screws through the fixing hole 21B to secure the housing 21 to the slide rail 14.

[0053] In some optional embodiments, the front upper surface of the slide groove 21A has a recess for cooperating with a protrusion located on the front upper surface of the slide rail 14 to fix the housing 21 to the slide rail 14 .

[0054] This embodiment provides another method for securing the vertical air conditioner indoor unit 20 after it is installed in place, that is, the slide groove 21A forms a recess on the front upper surface, and when the vertical air conditioner indoor unit 20 is installed in place, the protrusion on the front upper surface of the slide rail 14 just extends into the recess, thereby clamping the housing 21 and the slide rail 14 in the front-to-back direction.

[0055] The notch formed on the front upper surface of the slide 21A can be a groove formed concavely on the front upper surface of the slide 21A, or it can be a through hole extending vertically through the front upper surface of the slide 21A. Simultaneously, the raised portion on the front upper surface of the slide rail 14 can be integrally formed with the slide rail 14, or it can be movably disposed vertically within the front end of the slide rail 14 and protrude from the front upper surface of the slide rail 14 under the drive of a spring. In an embodiment in which the raised portion is movably disposed vertically, the raised portion can be retracted into the slide rail 14 during the push-in installation process of the vertical air conditioner indoor unit 20 and can be ejected upward when the vertical air conditioner indoor unit 20 is in place. When the vertical air conditioner indoor unit 20 needs to be pulled outward to be removed, the raised portion can be pressed downward from the notch exposed inside the housing 21 to release the raised portion from securing the housing 21.

[0056] In some optional embodiments, the air inlet 22A and the air outlet 22B extend longitudinally and are spaced apart in the transverse direction.

[0057] refer to Figure 2 As shown, the air inlet 22A and the air outlet 22B of this embodiment extend longitudinally on the front panel 22. Therefore, the air inlet 22A and the air outlet 22B are laterally spaced apart on either side of the front panel 22. The spacing between the air inlet 22A and the air outlet 22B can reduce the possibility that the heat exchange airflow blown out of the air outlet 22B is directly re-inhaled by the air inlet 22A, thereby improving the cooling or heating efficiency of the indoor environment of the vertical air conditioner indoor unit 20.

[0058] Figure 4 yes Figure 1 A cross-sectional schematic diagram of a vertical air conditioner indoor unit 20 of the air conditioner indoor unit system 10 is shown; Figure 5 yes Figure 1 Another cross-sectional schematic diagram of the vertical type air conditioner indoor unit 20 of the air conditioner indoor unit system 10 is shown.

[0059] refer to Figure 4 and Figure 5 As shown, in some optional embodiments, the vertical air conditioner indoor unit 20 further includes one or more vertical guide plates 26. The vertical guide plates 26 are provided at the air outlet 22B and extend longitudinally to change the left-right direction of the air flow.

[0060] In this embodiment, the vertical guide plate 26 extends in the same direction as the air outlet 22B and is used to change the left-right direction of the outlet airflow. It will be appreciated that the rotation axis of the vertical guide plate 26 also extends longitudinally, allowing for lateral swinging. The upper and lower ends of the vertical guide plate 26 can be rotatably connected to the front panel 22 or the housing 21, and at least one end is provided with a drive motor to drive the vertical guide plate 26 for rotation. If there are multiple vertical guide plates 26, the multiple vertical guide plates 26 can be transmission-connected and rotate synchronously.

[0061] In some optional embodiments, the rotation axis of one of the one or more vertical guide plates 26 is located on a side of the air outlet 22B close to the air inlet 22A.

[0062] refer to Figure 5 As shown, the rotation axis of a vertical guide plate 26 of the vertical air conditioner indoor unit 20 of this embodiment is located on the side of the air outlet 22B close to the air inlet 22A. Therefore, when it rotates, it also rotates around the rotation axis close to the side of the air outlet 22B, thereby blocking the outlet air flow when the air outlet 22B is opened, preventing the outlet air flow from flowing in the direction close to the air inlet 22A, so as to further reduce the heat exchange air flow blown out of the air outlet 22B from being directly re-inhaled by the air inlet 22A.

[0063] In some optional embodiments, the vertical air conditioner indoor unit 20 may further include an air inlet grille. The air inlet grille is removably mounted on the front panel 22 and defines a grille-shaped air inlet 22A. Furthermore, the vertical air conditioner indoor unit 20 may further include an air inlet filter positioned behind the air inlet grille. Users can replace or clean the air inlet filter by simply removing the air inlet grille without having to completely disassemble the front panel 22, thereby simplifying cleaning of the vertical air conditioner indoor unit 20. Alternatively, a dust filter may be provided on the air inlet grille, allowing users to simply remove and clean the air inlet grille.

[0064] In some optional embodiments, the vertical air conditioner indoor unit 20 further includes a crossflow fan 23, a heat exchanger 24, and an air supply duct 25. The crossflow fan 23 is disposed longitudinally within the housing 21. The heat exchanger 24 is disposed between the crossflow fan 23 and the air inlet 22A. The air supply duct 25 is disposed within the housing 21 and connects the crossflow fan 23 to the air outlet 22B.

[0065] The vertical air conditioner indoor unit 20 of this embodiment uses a crossflow fan 23 to deliver air. The extension direction of the crossflow fan 23, or the extension direction of its blades, is consistent with the extension direction of the air inlet 22A and the air outlet 22B. The length of the crossflow fan 23 is also similar to or consistent with the length of the air inlet 22A and the air outlet 22B. To fully cover the crossflow fan 23, the longitudinal length of the heat exchanger 24 should be no less than the length of the crossflow fan 23. The length of the crossflow fan 23 refers to the length of its blades.

[0066] To ensure smooth air intake and exhaust from the same side of the front panel 22 of the vertical air conditioner indoor unit 20, the volute formed by the air supply duct 25 of this embodiment is located near the air inlet 22A, thereby bringing the air inlet side of the cross-flow fan 23 closer to the air inlet 22A. To reduce the risk of the heat exchange airflow from the air outlet 22B being directly re-absorbed by the air inlet 22A, the air supply duct 25 of this embodiment extends outward at the air outlet 22B, away from the air inlet 22A, thereby directing the outlet airflow diagonally forward, away from the air inlet 22A. Combined with the air guide plate whose rotation axis is located on the side of the air outlet 22B close to the air inlet 22A, this significantly reduces the risk of the heat exchange airflow from the air outlet 22B being directly re-absorbed by the air inlet 22A.

[0067] refer to Figure 4 As shown, in some optional embodiments, the vertical air conditioner indoor unit 20 may further be provided with a plurality of transverse guide plates 27 spaced apart longitudinally in the air supply duct 25 to change the up and down direction of the outlet air flow.

[0068] refer to Figure 1 As shown, the air conditioner indoor unit system 10 of the present invention includes a vertical air conditioner indoor unit 20 , a cabinet 12 and two slide rails 14 .

[0069] The cabinet 12 defines a forwardly opening mounting cavity. The width of the mounting cavity matches the width of the housing 21 of the vertical air conditioner indoor unit 20 and is configured to accommodate the vertical air conditioner indoor unit 20. Two slide rails 14 are provided on one side wall of the mounting cavity. The shape and position of the slide rails 14 match the shape and position of the slide grooves 21A on the two lateral walls of the housing 21, and the slide rails 14 are configured to restrict the forward and backward movement of the vertical air conditioner indoor unit 20.

[0070] The installation cavity is the space inside the cabinet 12, which is jointly defined by the bottom wall, two lateral inner walls and the top wall of the cabinet 12. The installation cavity may further have a rear wall, which may be provided by the rear side wall of the cabinet 12, or by the wall or other vertical plane against which the rear side of the cabinet 12 is attached.

[0071] The cabinet 12 of this embodiment can be various cabinets 12 in a home environment including a wardrobe, a cupboard, a bookcase, and a TV cabinet, or it can be a cabinet-type storage space with the shape and function of the cabinet 12 formed on the wall, etc., which is not limited here.

[0072] In this embodiment, the width of the mounting cavity is adapted to the width of the housing 21 of the vertical air conditioner indoor unit 20. This means that the width of the mounting cavity is equal to or slightly greater than the width of the housing 21 of the vertical air conditioner indoor unit 20, so that the vertical air conditioner indoor unit 20 can be pushed into and installed in the cabinet 12 without leaving a noticeable gap. The width of the mounting cavity being slightly greater than the width of the housing 21 of the vertical air conditioner indoor unit 20 can generally be understood as the ratio of the width of the mounting cavity to the width of the housing 21 of the vertical air conditioner indoor unit 20 being greater than 1:1 and less than or equal to 105:100.

[0073] In some optional embodiments, the two slide grooves 21A have the same height, and the two slide rails 14 have the same height. The distance between the upper surface of each slide rail 14 and the bottom surface of the installation cavity is greater than or equal to the distance between the upper surface of each slide groove 21A and the bottom surface of the housing 21.

[0074] The bottom walls of some cabinets 12 are not close to the ground. Considering that the material of the cabinet 12 is usually wood, in order to prevent the heavy vertical air conditioner indoor unit 20 from being placed on the bottom of the cabinet 12 for a long time, which will cause the bottom of the cabinet 12 to bend and deform, the air conditioner indoor unit system 10 of this embodiment sets the distance between the upper surface of each slide rail 14 and the bottom surface of the installation cavity to be greater than or equal to the distance between the upper surface of each slide groove 21A and the bottom surface of the casing 21, so that the vertical air conditioner indoor unit 20 can be supported on the slide rail 14.

[0075] When the distance between the upper surface of each slide rail 14 and the bottom surface of the installation cavity is equal to the distance between the upper surface of each slide groove 21A and the bottom surface of the casing 21, the slide rail 14 and the bottom surface of the cabinet 12 simultaneously support the vertical air conditioner indoor unit 20, that is, the slide rail 14 and the bottom surface of the cabinet 12 jointly share the weight of the vertical air conditioner indoor unit 20.

[0076] The air conditioner indoor unit system 10 of this embodiment may also include an outdoor unit and a refrigerant pipeline connecting the outdoor unit and the vertical air conditioner indoor unit 20. The compressor, condenser, and throttling device in the outdoor unit are connected to the evaporator in the vertical air conditioner indoor unit 20 via the refrigerant pipeline. Together with other necessary components, they constitute the refrigeration cycle of the air conditioner indoor unit system 10. The vertical air conditioner indoor unit 20 can both cool and blow cooling air, and also have a heating function and blow heating air.

[0077] The vertical air conditioner indoor unit 20 of this embodiment serves as the indoor part of the air conditioner. In addition to the cooling and heating functions, it can also have additional functions such as dehumidification, humidification, air purification, and introduction of fresh air to the indoor environment.

[0078] The vertical air conditioner indoor unit 20 of this embodiment has both the air inlet 22A and the air outlet 22B disposed on the front panel 22, allowing air to enter and exit the vertical air conditioner indoor unit 20 from the front. Therefore, the vertical air conditioner indoor unit 20 is particularly suitable for being embedded in the cabinet 12, i.e., used as a built-in air conditioner indoor unit. However, it is understood that the vertical air conditioner indoor unit 20 of this embodiment can also be used without being disposed in the cabinet 12.

[0079] In the embodiment where the vertical air conditioner indoor unit 20 is installed as a built-in air conditioner indoor unit in the cabinet 12, the cabinet 12 used to house the vertical air conditioner indoor unit 20 can be any of various cabinets 12. The present invention does not limit the specific use of the cabinet 12. For example, the cabinet 12 can be used for household purposes, specifically in the kitchen, bathroom, living room, or bedroom. For example, the cabinet can be a wardrobe, a cupboard, a bookcase, a TV stand, etc.

[0080] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
