Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning equipment, and in particular to an air conditioner. Background Art

[0002] Air conditioners mainly consist of indoor and outdoor units. The indoor unit is usually used for cooling, heating, and ventilation in indoor environments.

[0003] The indoor unit includes a casing, a driving mechanism, a door body and other structures. The casing has an indoor air outlet and the driving mechanism is arranged inside the casing. The door body is installed at the indoor air outlet and connected to the driving mechanism. The driving mechanism is used to drive the door body to move to block or open the indoor air outlet so as to realize the function of the indoor unit.

[0004] Currently, the door body of the indoor unit usually adopts a rotating door to block the indoor air outlet or a sliding door to block the indoor air outlet. In the air conditioner that uses the sliding door to block the indoor air outlet, a driving mechanism is usually used to drive the sliding door to slide along the width direction of the indoor air outlet.

[0005] In the related art, to prevent the indoor unit's housing panel and panel holder from being too tightly mounted during installation, hindering installation and removal of the sliding door, and to prevent interference with the sliding door's movement due to a small gap between the panel and panel holder, a gap is typically left between the housing panel and panel holder on one side of the indoor air outlet widthwise. However, with this arrangement, cold air can easily flow in through the gap between the panel and panel holder during cooling, creating a temperature difference between the inside and outside of the panel and potentially increasing condensation on the panel. Utility Model Content

[0006] An embodiment of the present application discloses an air conditioner, which is used to reduce condensation on a casing panel and improve the overall appearance of an indoor unit of the air conditioner.

[0007] In order to achieve the above-mentioned object, the present application discloses an air conditioner, comprising:

[0008] Indoor unit;

[0009] The indoor unit includes:

[0010] A housing having an inner cavity, an indoor air outlet provided on the housing, and the indoor air outlet communicating with the inner cavity;

[0011] A door body, the door body being arranged at the indoor air outlet;

[0012] a driving mechanism, the driving mechanism being disposed in the inner cavity and configured to drive the door body to slide so as to cover or open the indoor air outlet;

[0013] The chassis includes:

[0014] A panel having the inner cavity, the panel comprising a first plate and a second plate, wherein the indoor air outlet is constructed between the first plate and the second plate;

[0015] a panel seat, the panel seat being disposed in the inner cavity, a gap being formed between the panel seat and the first plate, and a sliding space being formed between the panel seat and the second plate, the sliding space being configured for sliding of the door body;

[0016] The panel also includes:

[0017] a first flange, the first flange being connected to the first plate and located in the gap, the first flange protruding from the panel seat along a first direction, the first flange extending along a second direction, and being configured to at least partially block the gap;

[0018] The first direction is the width direction of the indoor air outlet, and the second direction is the air outlet direction of the indoor air outlet.

[0019] The present application also discloses an air conditioner, comprising:

[0020] Indoor unit;

[0021] The indoor unit includes:

[0022] A housing having an inner cavity, an indoor air outlet provided on the housing, and the indoor air outlet communicating with the inner cavity;

[0023] A door body, the door body being arranged at the indoor air outlet;

[0024] a driving mechanism, the driving mechanism being disposed in the inner cavity and configured to drive the door body to slide so as to cover or open the indoor air outlet;

[0025] The chassis includes:

[0026] A panel having the inner cavity, the panel comprising a first plate and a second plate, wherein the indoor air outlet is constructed between the first plate and the second plate;

[0027] a panel seat, the panel seat being disposed in the inner cavity, a gap being formed between the panel seat and the first plate, and a sliding space being formed between the panel seat and the second plate, the sliding space being configured for sliding of the door body;

[0028] The panel also includes:

[0029] a first convex edge, the first convex edge being provided on the first plate and located in the gap, the first convex edge protruding from the panel seat along a first direction, and the first convex edge extending along a second direction such that the first convex edge at least partially corresponds to the panel seat along the first direction;

[0030] The first direction is the width direction of the indoor air outlet, and the second direction is the air outlet direction of the indoor air outlet.

[0031] The air conditioner disclosed in the present application provides a first convex edge at the gap between the panel and the panel seat, and uses the first convex edge to form a blockage at the gap, thereby blocking the cold air that rushes into the gap when the indoor unit blows out cold air, which is beneficial to prevent a large temperature difference from forming between the inside and outside of the panel, thereby reducing the formation of condensation on the panel.

[0032] In addition, the first convex edge is set at the panel instead of at the panel seat near the indoor air outlet, which helps prevent the sliding door from contacting the first convex edge when sliding, thereby avoiding interference with the movement of the sliding door.

[0033] As an optional embodiment, the first convex edge is inclined relative to the second direction, and the first convex edge is configured to guide wind to be guided out of the indoor air outlet along the second direction.

[0034] When air is discharged from the indoor air outlet, it flows through the first convex edge. To prevent the first convex edge from blocking the air flow, the first convex edge is tilted relative to the second direction. This allows the air flowing out from the second direction to be effectively guided by the first convex edge. This prevents cold air from accumulating at the first convex edge during cooling, preventing overcooling of the panel and reducing condensation.

[0035] As an optional embodiment, the first convex edge has a first surface along the second direction and a second surface along the first direction, the second surface is connected to the first surface, and the indoor air outlet is constructed between the second surface and the second plate;

[0036] The panel seat has an air outlet surface along the first direction, the air outlet surface is close to the indoor air outlet, and along the second direction, a first angle is formed between the air outlet surface and the first surface, and the first angle is an obtuse angle.

[0037] When the wind is discharged from the indoor air outlet, it passes through the air outlet surface and then flows through the first convex edge. In order to avoid the first convex edge blocking the air outlet, the angle between the first surface of the first convex edge and the air outlet surface is set to an obtuse angle, so that the wind is discharged toward the outside of the indoor air outlet by the first surface after passing through the air outlet surface, thereby avoiding the accumulation of cold air on the first convex edge when the indoor unit is cooling, preventing the panel from being overcooled, and reducing the generation of condensation.

[0038] As an optional embodiment, the panel seat has an air outlet surface along the first direction, and the air outlet surface is close to the indoor air outlet;

[0039] The first convex edge has a second surface along the first direction, and a minimum distance between the second surface and the air outlet surface in the first direction is d, where d≥1 mm and d≤2 mm.

[0040] When setting the first convex edge, this application took into account the varying effects of the distance from the first convex edge to the air outlet during indoor cooling. Specifically, when the minimum distance is less than 1mm, the first convex edge's shielding effect on the gap is poor, hindering the flow of cold air. If the minimum distance is greater than 2mm, it can easily block the flow of cold air, hindering its diversion and causing it to accumulate on the first convex edge, leading to increased condensation. Thus, setting the minimum distance between 1mm and 2mm effectively shields the gap while also reducing airflow obstruction.

[0041] As an optional embodiment, the door body has an outer surface, and when the door body blocks the indoor air outlet, the first convex edge is at least partially projected onto the outer surface along the second direction.

[0042] Considering that the door body may not completely block the indoor air outlet, resulting in a portion of the indoor air outlet being exposed, the first convex edge can overlap with the door body in the second direction when the door body blocks the indoor air outlet. In this way, even if the door body does not completely block the indoor air outlet, leaving a gap, the first convex edge can cover the gap, thereby improving the overall appearance of the indoor unit.

[0043] As an optional embodiment, the first convex edge further has a third surface facing away from the inner cavity, the third surface forms a second angle with the first plate, and the second angle is an obtuse angle.

[0044] The third surface connects the first convex edge to the first plate. When air is discharged from the indoor air outlet, some of the air will pass through the first convex edge and finally be directed outward through the third surface. When the third surface forms an obtuse angle with the first plate, the indoor air outlet formed by the third surface and the second plate has a wider air outlet range than the indoor air outlet formed by the second surface and the second plate, which helps improve the air outlet effect.

[0045] As an optional embodiment, the panel also includes a first air cavity structure, which is arranged between the first plate and the first convex edge, and a first cavity is formed inside the first air cavity structure. The first air cavity structure is configured to enhance the structural strength of the panel.

[0046] Because the first flange and the first plate are connected at an angle, cracks, dents, and other structural defects are prone to forming at the junction during panel production. Providing a first air cavity structure at the junction of the first flange and the first plate allows air to flow into the first air cavity during panel production, which helps maintain pressure at the junction and stabilizes the formation of the junction. This reduces the likelihood of structural defects and improves the structural strength of the panel.

[0047] As an optional implementation, no baffle is provided on a portion of the first plate corresponding to the gap.

[0048] In the original panel structure, a baffle is provided on the side of the panel facing the inner cavity, adjacent to the gap, to block the cold air. However, the baffle can only block the cold air flowing into the space between the panel and the panel seat, and cannot effectively block the gap between the panel and the door body when the door body blocks the indoor air outlet. In the present application, by adopting a first convex edge, it is possible to effectively block the cold air flowing into the space between the panel and the panel seat, and also effectively block the gap between the panel and the door body when the door body blocks the indoor air outlet, so that the user cannot see the gap from the outside, thereby improving the overall appearance of the indoor unit.

[0049] As an optional embodiment, the door body includes a first edge side and a second edge side along the first direction, the first edge side can slide in the sliding space in the first direction, and a second convex edge is provided on the side of the first edge side facing away from the inner cavity. When the door body blocks the indoor air outlet, the first edge side is located in the sliding space, and the second convex edge is configured to at least block part of the sliding space.

[0050] Since the door body of this application is a sliding door, a sliding space is provided between the panel seat and the first plate for sliding considerations of the door body. Furthermore, when the door body blocks the indoor air outlet, a large gap remains between the door body and the first plate. This results in a large black edge visually appearing on the door body and panel of the indoor unit, affecting the user experience. However, this application provides a second convex edge on the door body, so that when the door body blocks the indoor air outlet, the second convex edge can block part of the sliding space, thereby reducing the visual impact of the black edge on the indoor unit's appearance.

[0051] As an optional embodiment, the first edge side extends along the second direction to form the second convex edge; and / or

[0052] The connection between the second convex edge and the first edge side is an arc-shaped transition, the door body is configured as an arc-shaped door body that bulges away from the inner cavity, the second convex edge is an arc-shaped bulge, and the bulging direction of the second convex edge is opposite to the bulging direction of the door body.

[0053] The second flange extends and forms on the door body, making it integral with the door body for easier manufacturing. Furthermore, the connection between the door body and the second flange and the shape of the two are curved to reduce the sharp angles between the door body and the second flange, preventing scratches on the human body and facilitating installation and transportation of the door body.

[0054] As an optional implementation, a protrusion height of the second protrusion along the second direction is L, where L is ≥ 2 mm and L is ≤ 5 mm.

[0055] By setting the second convex edge within a certain numerical range, it is helpful to prevent the convex height of the second convex edge from being too high and completely blocking the sliding space, thereby avoiding the second convex edge from affecting the sliding of the door body.

[0056] As an optional embodiment, the door body includes a first edge side and a second edge side along the first direction. When the door body blocks the indoor air outlet, the second edge side abuts against the panel seat. The second edge side is provided with a guard edge, and the guard edge is located on the side of the second edge side facing the inner cavity. The guard edge is configured to enhance the structural strength of the door body.

[0057] In a sliding door, the first edge is the primary moving side, and the door slides into the inner cavity from the second edge toward the first edge. To prevent interference with the movement of the first edge, the first edge is not provided with a flange. However, when the door slides out of the inner cavity, the second edge abuts the panel seat, stopping the door's movement. To prevent damage to the door from abutting the panel seat, a flange is provided on the second edge to enhance the door's structural strength and prevent damage.

[0058] As an optional embodiment, the door body also includes a second air cavity structure, which is connected between the second edge side and the retaining edge, and a second cavity is formed inside the second air cavity structure. The second air cavity structure is configured to strengthen the structural strength of the door body.

[0059] Since the sidewall is bent and connected to the door body, structural defects such as cracks and dents are easily generated at the connection between the sidewall and the second edge side during the production and molding of the door body. By providing a second air cavity structure at the connection between the second edge side and the sidewall, gas is introduced into the second air cavity during the production and molding of the door body, which helps to maintain pressure at the connection between the sidewall and the second edge side, thereby stabilizing the molding of the connection between the sidewall and the second edge side, thereby reducing the probability of structural defects in the door body and improving the structural strength of the door body.

DETAILED DESCRIPTION

[0074] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0075] In this application, the terms "inside" and "outside" indicate positions or location relationships based on the positions or location relationships shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments, and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or being constructed and operated in a specific orientation.

[0076] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0077] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0078] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0079] Commonly used air conditioners in households include indoor units and outdoor units. The indoor unit is usually used for cooling, heating, ventilation and other functions in the indoor environment. For the indoor unit, the indoor air outlet on the casing of the indoor unit is usually blocked by a door body, and then a driving mechanism is used to drive the door body to move relative to the indoor air outlet, thereby realizing the door body blocking and opening the indoor air outlet. Among them, the door body of the indoor unit often uses a rotating door to block the indoor air outlet or a sliding door to block the indoor air outlet. In air conditioners that use a sliding door to block the indoor air outlet, a driving mechanism is usually used to drive the sliding door to slide along the width direction of the indoor air outlet.

[0080] For sliding doors, the key is to achieve effective sliding of the sliding door. To avoid interference with the sliding door's movement, in related art, when the panel holder and panel of the housing are installed, a sliding space is left on one side of the width direction of the indoor air outlet to facilitate the sliding of the door body along the width direction of the door body. However, when the door body blocks the indoor air outlet, one side of the door body is located in the sliding space, and a large gap is left between the door body and the panel holder. This will result in a large black edge between the door body and the panel in terms of visual appearance, which may affect the user's perception. In addition, on the other side of the width direction of the indoor air outlet, for installation considerations of the panel and panel holder, a gap is usually left between the panel and the panel holder to facilitate the disassembly and assembly of the panel and the panel holder. After the panel is removed, the door body can be installed. However, during the cooling process of the indoor unit, cold air can easily flow through the gap between the panel holder and the panel, causing the panel temperature to drop. This creates a large temperature difference between the inside and outside of the panel, which can easily cause increased condensation on the panel and affect the normal use of the indoor unit.

[0081] Therefore, the gap problem between the panel seat and the panel has become an urgent problem to be solved in the design process of the indoor unit.

[0082] Based on this, the present application discloses an air conditioner indoor unit having a first convex edge disposed in the gap between the panel and the panel holder, thereby blocking cold air from entering between the panel and the panel holder. Furthermore, a second convex edge is disposed between the door and the panel on the side of the indoor air outlet, away from the first convex edge in the width direction. When the door blocks the indoor air outlet, the gap exposed by the sliding space is blocked, thereby reducing the visual black edge between the door and the panel, thereby improving the visual effect of the gap between the door and the panel.

[0083] In order to better understand the solution of the present application, the technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0084] See Figure 1 The embodiment of the present application discloses an air conditioner, which may include an indoor unit 100 and an outdoor unit (not shown). The indoor unit 100 is usually arranged indoors and exchanges heat with the indoor air through an indoor evaporator. The outdoor unit is arranged outdoors and connected to the indoor unit 100, mainly compressing the refrigerant and transporting it to the indoor unit 100 to achieve a cooling or heating effect.

[0085] In some embodiments, the air conditioner may be a wall-mounted air conditioner, and in this case, the indoor unit may be a wall-mounted indoor unit.

[0086] In some embodiments, the air conditioner may be a vertical air conditioner. In this case, the indoor unit may be a vertical air conditioner.

[0087] Please also see Figures 1 to 5 In some embodiments, the indoor unit 100 includes a casing 1 having an inner cavity 1a, and the casing 1 is provided with an indoor air outlet 1b and an indoor air inlet 1c, and the indoor air outlet 1b and the indoor air inlet 1c are connected to the inner cavity 1a.

[0088] In some embodiments, the indoor unit 100 includes a door body 2 , which is provided at the indoor air outlet 1 b , and is used to cover or open the indoor air outlet 1 b on the casing 1 .

[0089] In some embodiments, the door body 2 may be a rotating door or a sliding door.

[0090] In some embodiments, a driving mechanism (not shown) is provided in the inner cavity 1a, and the driving mechanism is configured to slide the door body 2 along a first direction to cover or open the indoor air outlet 1b.

[0091] Optionally, the driving mechanism may include a power source, a gear and a rack. The power source is connected to the gear transmission to drive the gear to rotate; the gear is engaged with the rack, and the rack is connected to the door body 2 to drive the sliding door to move synchronously, thereby realizing automatic opening or closing of the door body 2 without manual push, thereby improving the degree of automation.

[0092] In some embodiments, the power source may be, for example, an electric motor.

[0093] For example, the drive mechanism can drive the door body 2 to slide relative to the indoor air outlet 1b, or can drive the door body 2 to rotate relative to the indoor air outlet 1b to open or block the indoor air outlet 1b. When the drive mechanism drives the door body 2 to slide, the door body 2 is a sliding door, and when the drive mechanism drives the door body 2 to rotate, the door body 2 is a rotating door.

[0094] In some embodiments, the housing 1 includes a panel 11 and a panel seat 12 . The panel 11 has an inner cavity 1 a , and the panel seat 12 is disposed in the inner cavity 1 a .

[0095] In some embodiments, the panel 11 includes a first plate 111 and a second plate 112 , a gap 111a is formed between the panel seat 12 and the first plate 111 , and a sliding space 112a is formed between the panel seat 12 and the second plate 112 , and the sliding space 112a is configured for the door body 2 to slide along the first direction.

[0096] In some embodiments, the indoor unit 100 includes a heat exchange volute (not shown).

[0097] In some embodiments, the heat exchange volute is disposed in the inner cavity 1a.

[0098] In some embodiments, the indoor unit 100 includes an indoor heat exchanger 3 .

[0099] In some embodiments, the indoor heat exchanger 3 is disposed in the heat exchange volute, and the indoor heat exchanger 3 is used to exchange heat with the indoor air entering the heat exchange volute.

[0100] In some embodiments, the indoor unit 100 includes a heat exchange blower (not shown).

[0101] In some embodiments, the heat exchange fan is provided in the heat exchange volute, and the heat exchange fan is located in front of the indoor heat exchanger 3. The heat exchange fan is used to provide power for the flow of indoor air.

[0102] Driven by the heat exchange fan, the indoor air enters the heat exchange volute from the heat exchange indoor air inlet 1c and exchanges heat with the indoor heat exchanger 3. The indoor air after heat exchange is discharged from the heat exchange volute through the heat exchange outlet and then discharged from the indoor air outlet 1b.

[0103] That is, the heat exchange volute is used to accommodate the indoor heat exchanger 3 and the heat exchange fan, and provide an air cavity for the indoor heat exchanger 3 and the heat exchange fan.

[0104] In some embodiments, the indoor unit 100 includes a rotor (not shown) disposed within the interior cavity 1a along the height of the housing 1, with the rotor's axis of rotation perpendicular to the horizontal plane. The rotor can be driven by a motor. When the vertical air conditioner is operating, the motor drives the rotor to rotate, causing the outside air to first pass through the indoor heat exchanger 3, undergo heat exchange with the indoor heat exchanger 3, enter the rotor, and be blown out through the indoor air outlet 1b.

[0105] In some embodiments, the indoor unit 100 includes an air guide structure 4 , which is provided at the indoor air outlet 1 b and located in the inner cavity 1 a .

[0106] Optionally, the air guide structure 4 includes an air guide plate 41, which is located at the indoor air outlet 1b. The air guide plate 41 can be rotated along the height direction of the indoor air outlet 1b and connected to the panel seat 12. The air guide plate 41 can guide the wind direction of the indoor air outlet 1b, so that the vertical air conditioner has a larger blowing range.

[0107] Optionally, there are multiple air guide plates 41, for example, two, three, four, etc., and the multiple air guide plates 41 can be arranged at intervals along the width direction of the indoor air outlet 1b.

[0108] In some embodiments, an air conditioner outdoor unit includes an indoor casing, an outdoor heat exchanger, and an outdoor fan.

[0109] In some embodiments, an outdoor accommodation space is provided in the outdoor casing 1 , wherein the outdoor fan and the outdoor heat exchanger are provided in the outdoor accommodation space.

[0110] In some embodiments, the outdoor housing 1 is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are connected to the outdoor storage space. The outdoor air inlet is used to introduce outdoor air into the outdoor storage space, and the outdoor air outlet is used to draw air from the outdoor storage space to the outside of the outdoor storage space.

[0111] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor accommodation space from the outdoor air inlet and exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor accommodation space from the outdoor air outlet.

[0112] In some embodiments, the air-conditioning outdoor unit further includes a compressor and a throttling device, and the compressor and the throttling device are both arranged in the outdoor accommodation space.

[0113] In some embodiments, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0114] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0115] In some embodiments, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0116] In some embodiments, the throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0117] In some embodiments, the evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas at a low temperature and low pressure to the compressor.

[0118] In some embodiments, the evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the entire cycle, the temperature of the indoor space can be adjusted.

[0119] In some embodiments, among the indoor heat exchanger 3 and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger 3 is used as a condenser, the air conditioner is used as a heater in the heating mode, and when the indoor heat exchanger 3 is used as an evaporator, the air conditioner is used as a cooler in the cooling mode.

[0120] For ease of explanation, Figures 1 to 10 In this example, a vertical indoor unit is used as an example.

[0121] See Figures 5 to 7 In some embodiments, the panel 11 includes a first flange 13. The first flange 13 is connected to the first plate 111 and is located in the gap 111a between the first plate 111 and the panel seat 12. The first flange 13 is configured to at least partially block the gap 111a. By providing the first flange 13 in the gap 111a between the first plate 111 and the panel seat 12, the housing 1 blocks the gap 111a, thereby reducing the amount of cold air that can enter the gap 111a between the panel 11 and the panel seat 12 during cooling operation of the indoor unit 100.

[0122] For example, since the panel 11 and the panel seat 12 both have a gap 111 a in the length direction of the indoor air outlet 1 b , the first protruding edge 13 is provided in the length direction of the indoor air outlet 1 b .

[0123] In some embodiments, the first protrusion 13 protrudes from the panel seat 12 along the first direction X, and the first protrusion 13 extends along the second direction Y, so that the first protrusion 13 at least partially corresponds to the panel seat 12 along the first direction X.

[0124] For example, when the first flange 13 protrudes from the panel seat 12 in the first direction and extends in the second direction Y, the first flange 13 may cover a portion of the panel seat 12, and when viewed from the second direction Y, the first flange 13 may obscure the panel seat 12. When the indoor air outlet 1b is closed, the first flange 13 may completely obstruct the panel seat 12, preventing it from being exposed. When the indoor air outlet 1b is open, the first flange 13 may obstruct the gap 111a between the panel 11 and the panel seat 12, preventing it from being exposed, thereby enhancing the aesthetics of the indoor unit 100.

[0125] It should be noted that in Figures 1 to 11In the example given, the direction indicated by X is the first direction X, and the direction indicated by Y is the second direction Y. Specifically, in the indoor unit 100, the first direction X can be the width of the indoor air outlet 1b, and the second direction Y can be the direction of air blowing from the inner cavity 1a to the indoor air outlet 1b. The direction indicated by Z is the length of the indoor air outlet 1b. In a vertical indoor unit, the direction indicated by Z can also be the height of the indoor unit 100.

[0126] In some implementations, the first protruding edge 13 is inclined relative to the second direction Y, and the first protruding edge 13 is configured to guide the wind along the second direction Y to exit the indoor air outlet 1 b.

[0127] It is understandable that during the cooling process of the air conditioner, part of the cold air formed in the inner cavity 1a of the casing 1 will flow through the panel seat 12 and then flow through the first plate 111 and / or the second plate 112, and finally be discharged into the room.

[0128] For example, a first flange 13 is provided on the first plate 111, tilted along the second direction Y. When air flows from the panel seat 12 toward the first plate 111, the air passes through the first flange 13 before being discharged. The first flange 13 guides the air flowing through the first plate 111, thereby preventing cold air from accumulating on the first plate 111, causing the first plate 111 to overcool and increase condensation on the first plate 111.

[0129] It can be understood that the first convex edge 13 is located at the gap 111 a , and in order to prevent cold air from being introduced into the gap 111 a , the outlet direction of the first convex edge 13 is a direction away from the gap 111 a .

[0130] In some embodiments, the first flange 13 has a first surface 131 along the second direction Y and a second surface 132 along the first direction. The first surface 131 is connected to the second surface 132 , and an indoor air outlet 1b is constructed between the second surface 132 and the second plate 112 .

[0131] During the cooling process of the air conditioner, part of the cold air generated in the inner cavity 1a of the casing 1 will flow through the panel seat 12 and then through the first surface 131. Finally, the cold air is discharged from the second surface 132 at the indoor air outlet 1b formed by the second surface 132 and the second plate 112. It can be seen that the present application guides the cold air through the first surface 131 to the second surface 132 and finally out of the indoor air outlet 1b, thereby preventing the cold air from entering the gap 111a between the first plate 111 and the panel seat 12.

[0132] Exemplarily, the first surface 131 is inclined relative to the second direction, and the cold air is guided by the first surface 131 to be away from the gap 111 a and out of the indoor air outlet 1 b.

[0133] In some embodiments, the panel seat 12 has an air outlet surface 12a along the first direction, the air outlet surface 12a is adjacent to the indoor air outlet 1b, and along the second direction Y, there is a first angle α between the air outlet surface 12a and the first surface 131, and the first angle α can be an obtuse angle.

[0134] For example, in Figure 7 As shown, the air outlet surface 12a is close to the first surface 131, and the air outlet surface 12a and the first surface 131 form a first angle α, which is an obtuse angle, so that when the air conditioner discharges cold air, it can effectively guide the air along the first angle α formed by the air outlet surface 12a and the first surface 131, avoiding the first angle α being too small, so that the second surface 132 blocks the cold air discharged by the air outlet surface 12a.

[0135] In some embodiments, the first angle α is less than 180°, so that the first convex edge 13 can partially cover the panel seat 12 in the second direction Y.

[0136] Exemplarily, when the indoor air outlet 1b is blocked by the door body 2, the first surface 131 faces the inner cavity 1a in the second direction, so that the first protrusion can cover the panel seat 12 in appearance to prevent the panel seat 12 from being exposed.

[0137] In some embodiments, the first angle α is greater than 90°. This prevents the angle between the first surface 131 and the air outlet surface 12a from being too small, preventing the first surface 131 from blocking the cold air from the air outlet surface 12a, and preventing the cold air from gathering on the first convex edge 13, causing the first convex edge 13 to be overcooled and causing increased condensation.

[0138] In some embodiments, the first angle α may range from 90° to 180°. For example, the first angle α may range from 90° to 110°, 100° to 120°, 110° to 130°, 120° to 140°, 130° to 150°, 140° to 160°, 150° to 170°, 160° to 180°, etc. For example, the first angle α may be 91°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 179°, etc.

[0139] The present application sets the range of the first angle α within these numerical ranges, which is beneficial to the effective wind guidance of the first angle α formed by the wind outlet surface 12a and the first surface 131. It can also avoid the situation where the first angle α is too large, resulting in insufficient external shielding effect, and can also avoid the situation where the first angle α is too small, resulting in wind blocking and increased condensation on the first convex edge 13.

[0140] In some embodiments, the minimum distance between the second surface 132 and the air outlet surface 12 a in the first direction X is d.

[0141] It is understandable that in Figure 7 In the example shown, the minimum distance d between the second surface 132 and the air outlet surface 12 a is the distance that the first protruding edge 13 protrudes relative to the panel seat 12 in the first direction X.

[0142] In some embodiments, d ≥ 1 mm.

[0143] For example, if the first flange 13 is not provided and the door 2 blocks the indoor air outlet 1b, a portion of the panel seat 12 is exposed in the second direction Y, resulting in an inconsistent appearance of the indoor unit 100 in the second direction Y. The exposed portion of the panel seat 12 in the first direction X is approximately 1 mm long. Therefore, providing the first flange 13 on the first plate 111 blocks the exposed portion of the panel seat 12, thereby improving the appearance of the indoor unit 100.

[0144] In some embodiments, d≤2 mm.

[0145] For example, since the indoor air outlet 1b will discharge cold air in the second direction Y, to prevent the first flange 13 from blocking the indoor air outlet 1b and thus obstructing the outlet of cold air, the first flange 13 should be minimized. Thus, by setting d to be less than or equal to 2 mm, the first flange 13 can block the panel seat 12 while also reducing the obstruction of the indoor air outlet 1b by the first flange 13.

[0146] In some embodiments, the minimum distance d may be 1.0 mm to 2.0 mm, for example, 1.0 mm to 1.2 mm, 1.1 mm to 1.3 mm, 1.2 mm to 1.4 mm, 1.3 mm to 1.5 mm, 1.4 mm to 1.6 mm, 1.5 mm to 1.7 mm, 1.6 mm to 1.8 mm, 1.7 mm to 1.9 mm, or 1.8 mm to 2.0 mm. For example, the minimum distance d may be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm.

[0147] The present application sets a minimum distance d between the second surface 132 of the first flange 13 and the air outlet surface 12a along the first direction X to limit the distance that the first flange 13 protrudes from the air outlet surface 12a in the first direction X, so that the first flange 13 can block the panel seat 12 while reducing the obstruction of the first flange 13 to the air outlet of the indoor air outlet 1b, thereby improving the appearance of the indoor unit 100 and reducing the accumulation of cold air on the first flange 13, thereby reducing the generation of condensation on the first flange 13.

[0148] In some embodiments, no baffle is provided on the portion of the first plate 111 corresponding to the gap 111 a .

[0149] For example, in the existing panel structure, a baffle is provided on the side of the panel 11 facing the inner cavity 1a, adjacent to the gap 111a, to block cold air. However, the baffle can only block cold air flowing between the panel 11 and the panel seat 12, and cannot effectively block the gap between the panel 11 and the door body 2 when the door body 2 blocks the indoor air outlet 1b. In the present application, by adopting the first flange 13, it is possible to effectively block cold air flowing between the panel 11 and the panel seat 12, and also effectively block the gap between the panel 11 and the door body 2 when the door body 2 blocks the indoor air outlet 1b.

[0150] In some embodiments, the door body 2 has an outer surface 2a.

[0151] It can be understood that the outer surface 2a is the appearance surface of the door body 2 when shielding the indoor air outlet 1b.

[0152] Optionally, when the door body 2 blocks the indoor air outlet 1b, the first flange 13 is at least partially projected onto the outer surface 2a along the second direction Y. That is, in the second direction Y, the first flange 13 and the door body 2 overlap in appearance, making the door body 2 and the first plate 111 similar in appearance, making the door body 2 and the panel 11 more integrated in appearance, which is beneficial to improving the overall appearance of the indoor unit 100.

[0153] In some embodiments, the first flange 13 further has a third surface 133 facing away from the inner cavity 1 a , and the third surface 133 forms a second angle β with the first plate 111 .

[0154] It is understandable that in Figure 6 and Figure 7 In the example, the third surface 133 is the connecting surface between the first convex edge 13 and the first plate 111 , and the angle formed by the third surface 133 and the first plate 111 is the second angle β formed by the first convex edge 13 and the first plate 111 .

[0155] In some embodiments, the second angle β is greater than or equal to 90°. For example, if the second angle β is less than 90°, the angle between the first flange 13 and the first plate 111 is small, which causes the first flange 13 to bend toward the gap 111a, resulting in the first flange 13 being unable to effectively block both the panel seat 12 and the gap 111a.

[0156] In some embodiments, the second angle β is less than or equal to 180°. For example, if the second angle β is greater than 180°, the first flange 13 bends away from the inner cavity 1a relative to the first plate 111, causing the first flange 13 to tilt relative to the first plate 111, making it difficult for the first flange 13 to block the gap 111a, causing cold air to enter through the gap 111a.

[0157] In some embodiments, the second angle β may be in the range of 90°-180°. For example, the second angle β may be in the range of 90°-110°, 100°-120°, 110°-130°, 120°-140°, 130°-150°, 140°-160°, 150°-170°, 160°-180°, etc. For example, the second angle β may be 91°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 179°, etc. That is, the second angle β may be an obtuse angle.

[0158] The present application sets the second angle β to an obtuse angle, so that the first flange 13 can effectively block the gap 111a while also blocking the panel seat 12. In the first direction X, the first flange 13 and the second plate 112 form the indoor air outlet 1b. Compared to the indoor air outlet 1b formed by the second surface 132 and the second plate 112, the indoor air outlet 1b formed by the third surface 133 and the second plate 112 has a larger opening due to the obtuse angle formed by the third surface 133 and the first plate 111, which facilitates the air outlet 1b to the indoor unit 100.

[0159] In some embodiments, the panel 11 also includes a first air cavity structure 113, which is arranged between the first plate 111 and the first flange 13, and a first cavity 113a is formed inside the first air cavity structure 113. The first air cavity structure 113 is configured to strengthen the structural strength of the panel 11.

[0160] In the panel 11 of the present application, since the first plate 111 is bent and connected to the first flange 13, in order to enhance the connection strength between the first plate 111 and the first flange 13, a first air cavity structure 113 is provided at the connection between the first plate 111 and the first flange 13 to enhance the connection strength between the first plate 111 and the first flange 13, thereby facilitating the enhancement of the overall structural strength of the panel 11.

[0161] Exemplarily, the panel 11 is produced by injection molding. During the production process of the panel 11, gas can be injected into the first cavity 113a to form a first air cavity structure 113. The injected gas is beneficial to maintaining the structure at the connection between the first plate 111 and the first flange 13 during molding, eliminating cracks caused by thermal expansion and contraction between the first plate 111 and the first flange 13 during injection molding, thereby improving the structural strength of the panel 11 after molding.

[0162] Please also see Figures 8 to 11 In some embodiments, the door body 2 includes a first edge side 21 and a second edge side 22 along the first direction X, and the first edge side 21 can slide in the sliding space 112a in the first direction X.

[0163] It is understandable that when the door body 2 blocks the indoor air outlet 1 b , the second edge side 22 is adjacent to the first plate 111 , and the first edge side 21 is located in the sliding space 112 a and adjacent to the second plate 112 .

[0164] In some embodiments, a second flange 23 is provided on the side of the first edge side 21 facing away from the inner cavity 1a. When the door body 2 blocks the indoor air outlet 1b, the first edge side 21 is located in the sliding space 112a, and the second flange 23 is configured to at least block part of the sliding space 112a.

[0165] To ensure that the door body 2 can effectively slide within the sliding space 112a, a large gap is left between the first edge 21 of the sliding space 112a and the second plate 112 when the door body 2 blocks the indoor air outlet 1b. Consequently, when the door body 2 blocks the indoor air outlet 1b, a large gap is left between the door body 2 and the second plate 112 at the first edge 21. This results in a large black gap between the door body 2 and the panel 11, which affects the appearance of the indoor unit 100.

[0166] In this regard, when the door body 2 blocks the indoor air outlet 1b, the second flange 23 provided on the first edge side 21 of the present application can block the gap between the first edge side 21 and the second plate 112. This helps to enhance the visual integration of the door body 2 and the second plate 112, and helps to improve the overall appearance of the indoor unit 100.

[0167] In some embodiments, the second flange 23 has a height L along the second direction Y, and L is greater than or equal to 2 mm. This configuration facilitates the second flange 23 to at least partially block the sliding space 112a between the door body 2 and the second plate 112 when the door body 2 blocks the indoor air outlet 1b, thereby reducing the visual effect of the black gap caused by the sliding space 112a.

[0168] For example, if L is less than 2 mm, the portion of the sliding space 112 a cannot be effectively shielded, and the visual impact of the black gap is difficult to weaken.

[0169] In some embodiments, L is less than or equal to 5 mm. To facilitate sliding of the door body 2, a sliding space 112a of approximately 6 mm is left between the door body 2 and the second plate 112. To prevent the second flange 23 from interfering with the sliding of the door body 2, the raised height L of the second flange 23 is set to be less than or equal to 5 mm.

[0170] If L is greater than 5 mm, the second flange 23 may come into contact with the second plate 112 during the sliding process, thereby interfering with the sliding of the door body 2 .

[0171] In some embodiments, the raised height L of the second flange 23 may be 2 mm to 5 mm, for example, 2 mm to 3 mm, 2.5 mm to 3.5 mm, 3 mm to 4 mm, 3.5 mm to 4.5 mm, 4 mm to 5 mm, etc. For example, the raised height L of the second flange 23 may be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc.

[0172] In this way, the second convex edge 23 is prevented from being raised too high, thereby preventing the second convex edge 23 from interfering with the sliding of the door body 2. The second convex edge 23 can also block the sliding space 112a between the door body 2 and the second plate 112, thereby reducing the visual impact of the black gap formed by the sliding space 112a.

[0173] In some embodiments, the first edge side 21 extends along the second direction Y to form a second flange 23 . In other words, the second flange 23 is integrally formed with the first edge side 21 to facilitate the arrangement of the second flange 23 .

[0174] In some embodiments, the connection between the second flange 23 and the first edge side 21 is an arc-shaped transition, and the door body 2 is configured as an arc-shaped door body 2 that bulges away from the inner cavity 1a. The second flange 23 can be an arc-shaped bulge, and the bulging direction of the second flange 23 is opposite to the bulging direction of the door body 2.

[0175] For example, the door body 2 may not be arc-shaped, and the second convex edge 23 may be an arc-shaped convex edge.

[0176] Exemplarily, the door body 2 may be a curved door body 2 , and the second convex edge 23 may be a curved convex edge.

[0177] Since the second flange 23 is located at the edge of the door body 2, in order to prevent the second flange 23 from scratching the human body during the installation and transportation of the door body 2, the second flange 23 itself and the connection with the first edge side 21 are configured to be curved to reduce the sharp corners on the door body 2, thereby facilitating the installation and transportation of the door body 2. The door body 2 can also be configured to be curved, which is beneficial for utilizing the curved shape to improve the overall support performance of the door body 2 and reduce the risk of damage to the door body 2.

[0178] In some embodiments, when the door body 2 blocks the indoor air outlet 1b, the second edge side 22 abuts against the panel seat 12, and the second edge side 22 is provided with a retaining edge 24, which is located on the side of the second edge side 22 facing the inner cavity 1a, and the retaining edge 24 is configured to enhance the structural strength of the door body 2.

[0179] Exemplarily, the retaining edge 24 is bent and connected to the second edge side 22, and the angle formed by the retaining edge 24 and the second edge side 22 is a right angle or an acute angle to avoid the angle between the retaining edge 24 and the second edge side 22 being too large, so that the retaining edge 24 interferes with the movement of the door body 2 when the door body 2 blocks the indoor air outlet 1b.

[0180] Exemplarily, the first edge side 21 is not provided with the rib 24 . Since the first edge side 21 is the main moving side during sliding, in order to avoid the influence of the rib 24 on the sliding of the first edge side 21 , the first edge side 21 is not provided with the rib 24 .

[0181] Considering that the second edge will abut against the panel seat 12 when the door body 2 blocks the indoor air outlet 1b to stop the sliding of the door body 2, in order to avoid damage to the door body 2 during the abutment between the door body 2 and the panel seat 12, the present application provides a retaining edge 24 on the second edge side 22 to enhance the structural strength of the second edge side 22.

[0182] See Figure 11 In some embodiments, the door body 2 also includes a second air cavity structure 25, which is connected between the second edge side 22 and the retaining edge 24. A second cavity 25a is formed inside the second air cavity structure 25, and the second air cavity structure 25 is configured to strengthen the structural strength of the door body 2.

[0183] The door body 2 in the present application has a second edge side 22 that is bent and connected to the retaining edge 24. In order to enhance the connection strength between the second edge side 22 and the retaining edge 24, a second air cavity structure 25 is provided at the connection between the second edge side 22 and the retaining edge 24, thereby enhancing the connection strength between the second edge side 22 and the retaining edge 24, thereby facilitating enhancing the overall structural strength of the door body 2.

[0184] Exemplarily, the door body 2 is produced by injection molding. During the production process of the door body 2, gas can be injected into the second cavity 25a to form a second air cavity structure 25. The injected gas is beneficial to maintaining the pressure of the structure at the connection between the second edge side 22 and the retaining edge 24 during molding, eliminating cracks caused by thermal expansion and contraction between the second edge side 22 and the retaining edge 24 during injection molding, thereby improving the structural strength of the door body 2 after molding.
