[0045] Figure 1 is a schematic diagram of an indoor unit 20 of an air conditioner according to an embodiment of the present utility model; Figure 2 is Figure 1Schematic diagram of the front panel 22 of the indoor unit 20 of the air conditioner shown.

[0046] Reference Figure 1 and Figure 2 As shown, the present utility model provides an indoor unit 20 of an air conditioner. The indoor unit 20 of the air conditioner includes a housing 21 and a front panel 22. The front panel 22 is arranged on the front side of the housing 21; an air inlet 22B is provided at the upper part of the front panel 22, and an air outlet 22A is provided at the lower part of the front panel 22; there is a gap between the air inlet 22B and the air outlet 22A, and the ratio of the longitudinal width of the gap to the longitudinal width of the air outlet 22A is greater than or equal to 2:3.

[0047] In the indoor unit 20 of the air conditioner in this embodiment, both the air inlet 22B and the air outlet 22A are provided on the front panel 22, so that the indoor unit 20 of the air conditioner intakes air and discharges air from the front side at the same time. Among them, the air inlet 22B is provided at the upper part of the front panel 22, and the air outlet 22A is provided at the lower part of the front panel 22, so that the indoor unit 20 of the air conditioner intakes air from a relatively high position and discharges air to a relatively low position.

[0048] If the air inlet 22B and the air outlet 22A are provided on the same side, because the distance between the air inlet 22B and the air outlet 22A is too close, convection is likely to occur at the position between the air inlet 22B and the air outlet 22A. When the indoor unit 20 of the air conditioner is refrigerated, since the temperature of the outgoing air flow is often significantly lower than the temperature of the incoming air flow, it is easy to cause condensation at the position between the air inlet 22B and the air outlet 22A of the indoor unit 20 of the air conditioner.

[0049] Therefore, the indoor unit 20 of the air conditioner in this embodiment particularly sets a gap with an appropriate longitudinal width between the air inlet 22B and the air outlet 22A, so that the air inlet 22B and the air outlet 22A are far away from each other, thereby reducing the convection between the air inlet 22B and the air outlet 22A, and further solving the condensation problem of the indoor unit 20 of the air conditioner.

[0050] The air inlet 22B and the air outlet 22A of the indoor unit 20 of the air conditioner in this embodiment are respectively provided at the upper and lower parts of the front panel 22 and extend horizontally on the front panel 22 respectively. Therefore, the width of the gap between the air inlet 22B and the air outlet 22A is the distance between the lower side edge of the air inlet 22B and the upper side edge of the air outlet 22A. It can also be understood that the longitudinal width of the air outlet 22A is the distance between the upper side edge and the lower side edge of the air outlet 22A.

[0051] In this embodiment, specifically, the ratio of the longitudinal width between the air inlet 22B and the air outlet 22A to the longitudinal width of the air outlet 22A is set to be greater than or equal to 2:3, so as to ensure that there is a sufficiently wide interval between the air inlet 22B and the air outlet 22A. When the air outlet flow and the air inlet flow are far away from each other, it is more difficult to form convection near the front panel 22, thus reducing the condensation of water vapor here.

[0052] Furthermore, in some alternative embodiments, the air conditioner indoor unit 20 can set the ratio of the longitudinal width of the air inlet 22B to the longitudinal width of the front panel 22 to be greater than or equal to 1:3, so as to prevent the interval between the air inlet 22B and the air outlet 22A from being too wide, resulting in the air inlet 22B being too small.

[0053] Figure 3 Yes Figure 1 Another schematic diagram of the air conditioner indoor unit 20 shown.

[0054] Reference Figure 3 As shown, in some alternative embodiments, the air conditioner indoor unit 20 further includes a computer board installation groove 23 and a computer board 24. The computer board installation groove 23 is arranged inside the housing 21; and the computer board installation groove 23 defines an installation cavity with an opening facing the interval. The computer board 24 is arranged in the installation cavity.

[0055] Since the air conditioner indoor unit 20 of this embodiment has a relatively wide interval between the air inlet 22B and the air outlet 22A, this embodiment further sets a computer board installation groove 23 in the housing 21 that is directly opposite to this interval position front and back, and arranges the computer board 24 in the computer board installation groove 23, thus making full use of this interval space. The front panel 22 of the air conditioner indoor unit 20 of this embodiment can be detachably arranged relative to the housing 21, so that after the front panel 22 is removed, the opening of the installation cavity of the computer board installation groove 23 is exposed forward, facilitating operations such as wiring and maintenance of the computer board 24 therein by the staff.

[0056] Reference Figure 2 And Figure 3 As shown, in some alternative embodiments, the front panel 22 includes a main board body 222 and a shielding plate 224. The air outlet 22A is opened at the lower part of the main board body 222, and the main board body 222 has an opening that penetrates front and back at the interval. The shielding plate 224 is arranged on the front side of the main board body 222 and is used to open and close the opening of the main board body 222 at the interval.

[0057] In order to make it more convenient to wire, repair, etc. the computer board 24, in this embodiment, the front panel 22 is set to include two parts, namely a main board body 222 and a shielding plate 224. The main board body 222 has an opening that penetrates through from front to back at the interval between the air inlet 22B and the air outlet 22A, and the shielding plate 224 is arranged on the front side of the main board body 222 and is used to open and close such an opening. The shielding plate 224 can be detachably arranged relative to the main board body 222, or can be rotatably arranged relative to the main board body 222. When the shielding plate 224 is opened, the opening of the main board body 222 at the interval between the air inlet 22B and the air outlet 22A is exposed, and the opening of the installation cavity of the computer board installation groove 23 is just opposite to the opening of the main board body 222, so that the staff can wire, repair, etc. the exposed computer board 24 without disassembling the front panel 22.

[0058] If the distance between the air inlet 22B and the air outlet 22A of the air conditioner indoor unit 20 is too close, it is not suitable to set the computer board 24, which is easily damaged after being affected by moisture, at the interval between the air inlet 22B and the air outlet 22A. However, in this embodiment, the interval between the air inlet 22B and the air outlet 22A is specifically set to be large enough so that it is not easy to condense moisture here, thus avoiding the problem that the computer board 24 is easily damaged by moisture when set here, and making full use of the interval space here.

[0059] Figure 4 It is a schematic diagram of the front panel 22 of the air conditioner indoor unit 20 according to another embodiment of the present invention.

[0060] Reference Figure 4 As shown, in some alternative embodiments, the air inlet 22B is opened in the upper part of the main board body 222. The front panel 22 further includes an air inlet baffle 226. The air inlet baffle 226 is rotatably arranged on the upper front side of the main board body 222 and is used to open and close the air inlet 22B.

[0061] The air conditioner indoor unit 20 of this embodiment can use an air inlet baffle 226 rotatably arranged on the main board body 222 of the front panel 22 to open and close the air inlet 22B as shown Figure 4 so that the air inlet 22B can be closed when the air conditioner indoor unit 20 is not working, avoiding the entry of dust and sundries, and making the appearance surface on the front side of the air conditioner indoor unit 20 more beautiful.

[0062] Further, in some alternative embodiments, the rotation axis of the air inlet baffle 226 is located at the lower side edge of the air inlet 22B.

[0063] Reference Figure 4As shown, the air conditioner indoor unit 20 of this embodiment makes the air inlet baffle 226 rotate around the rotation axis located at the lower side of the air inlet 22B, so that the air inlet area between the air inlet 22B of the main body 222 and the air inlet baffle 226 is mainly opened upward. The air conditioner indoor unit 20 mainly takes in air from the area higher than the air inlet baffle 226 and basically does not take in air from the side of the air inlet baffle 226 close to the air outlet 22A, thereby greatly reducing the situation of convection between the air inlet airflow and the air outlet airflow, and effectively solving the condensation problem of the air conditioner indoor unit 20.

[0064] refer to Figure 2 As shown, in some optional embodiments, the front panel 22 further includes an air inlet grille 226. The air inlet grille 226 is disposed on the upper front portion of the main body 222; the air inlet grille 226 is provided with a grille-shaped air inlet 22B.

[0065] The air inlet 22B of the air conditioner indoor unit 20 of this embodiment is provided on the air inlet grille 226 provided on the main body 222. The air inlet grille 226 forms a grille-like structure, so that the air inlet 22B is also grille-shaped. The grille-like structure on the air inlet grille 226 is used to prevent large-sized debris from falling in, and to shield the interior of the air conditioner indoor unit 20, so that the appearance of the front side of the air conditioner indoor unit 20 is more beautiful.

[0066] Figure 5 yes Figure 1 A cross-sectional schematic diagram of an air conditioner indoor unit 20 is shown.

[0067] refer to Figure 2 and Figure 5 As shown, further, in some optional embodiments, the air inlet grille 226 forms a plurality of grid bars spaced apart and extending transversely at the air inlet 22B, and each grid bar extends obliquely upward from the back to the front. The grid bars spaced apart form a grid-shaped air inlet 22B, and each grid bar extends obliquely upward from the back to the front so that the air inlet direction of the air conditioner indoor unit 20 is obliquely downward from the outside to the inside. Therefore, the air inlet 22B of the air conditioner indoor unit 20 of this embodiment inhales less air from the side close to the air outlet 22A, and the formed air inlet airflow is also reduced accordingly, thereby reducing the convection between the air inlet airflow and the air outlet airflow to a certain extent.

[0068] In some optional embodiments, an air supply duct connecting the air inlet 22B and the air outlet 22A is defined in the housing 21; the air conditioner indoor unit 20 further includes an air duct component 25. The air duct component 25 forms at least a part of the side wall of the air supply duct.

[0069] refer to Figure 5As shown, the air duct member 25 of the indoor unit 20 of the air conditioner in this embodiment forms a partial duct wall on the side of the air supply duct close to the air inlet 22B and is arranged close to the computer installation slot. In some alternative embodiments, the air duct member 25 and the computer installation slot can be spliced, that is, they are connected and fixed by snap fasteners, screws or other connection structures in cooperation with their own shapes. In some alternative embodiments, the air duct member 25 and the computer board installation slot 23 are integrally formed.

[0070] A water receiving tray needs to be provided at the bottom end of the evaporator to collect the condensed water formed on the evaporator. In some alternative embodiments, the water receiving tray can be integrally formed on the computer installation slot, and the computer installation slot can be used to support and fix the evaporator at the same time.

[0071] Reference Figure 5 As shown, in some alternative embodiments, the indoor unit 20 of the air conditioner further includes an air outlet baffle 26. The air outlet baffle 26 is rotatably arranged at the air outlet 22A for opening and closing the air outlet 22A. The rotation axis of the air outlet baffle 26 is located at the upper side edge of the air outlet 22A.

[0072] The indoor unit 20 of the air conditioner in this embodiment opens and closes the air outlet 22A through the air outlet baffle 26. Since the rotation axis of the air outlet baffle 26 is located at the upper side edge of the air outlet 22A, when the air outlet baffle 26 rotates to open the air outlet 22A, the air outlet baffle 26 itself will vertically separate the air inlet 22B and the air outlet 22A, thereby effectively reducing the upward flow of the air flow to a position close to the air inlet 22B.

[0073] Figure 6 is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0074] The air conditioner 10 in this embodiment includes an indoor unit 20 of the air conditioner, and may also include an outdoor unit of the air conditioner and a refrigerant pipeline connecting the two. The compressor, condenser, and throttling device in the outdoor unit of the air conditioner are connected to the evaporator in the indoor unit 20 of the air conditioner by the refrigerant pipeline, and together with other necessary components, they constitute the refrigeration cycle system of the air conditioner 10. On the side of the indoor unit 20 of the air conditioner, it can both refrigerate and blow the refrigerated air flow, and can also have a heating function and blow the heated air flow.

[0075] The indoor unit 20 of the air conditioner in this embodiment, as the indoor part of the air conditioner, in addition to having refrigeration and heating functions, can also additionally have functions such as dehumidifying, humidifying, air purifying, and introducing fresh air to the indoor environment.

[0076] The indoor unit 20 of the air conditioner in this embodiment arranges both the air inlet 22B and the air outlet 22A on the front surface of the housing, so that the indoor unit 20 of the air conditioner takes in and discharges air from the front side simultaneously. Therefore, it is especially suitable for being embedded and used in a cabinet, that is, being used as an embedded indoor unit 20 of the air conditioner.

[0077] In the embodiment where the air conditioner 10 is an embedded air conditioner 10, the cabinet for placing the indoor unit 20 of the air conditioner can be various cabinets and can be used for storing items. The specific use of the cabinet in the present utility model is not limited. For example, the cabinet can be for household use and can be specifically applied to the kitchen, bathroom, living room or bedroom. For example, the cabinet can be arranged in the kitchen to accommodate the indoor unit 20 of the air conditioner.

[0078] However, the air conditioner 10 in this embodiment is not limited to the embedded air conditioner 10. The indoor unit 20 of the air conditioner can either be the indoor part of the embedded air conditioner 10 installed in various cabinets or the indoor terminal unit of the central air conditioner, or can be the indoor part of the wall-mounted air conditioner 10 or other indoor units 20 of the air conditioner, which is not limited herein.

[0079] Up to this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, still, without departing from the spirit and scope of the present utility model, many other variations or modifications that conform to the principles of the present utility model can be directly determined or deduced based on the content disclosed in the present utility model.
