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] Existing air conditioner products include indoor units and outdoor units. The indoor unit is usually used for functions such as cooling, heating, and ventilation in the indoor environment.

[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] In related technologies, when a door is driven by a drive mechanism, the excessive weight of the door itself can easily affect the drive mechanism, causing it to be overloaded. Reducing the door's own weight can easily reduce its structural strength, causing it to be damaged when subjected to heavy loads during installation, transportation, and movement.

[0022] A door body, the door body being arranged at the indoor air outlet;

[0023] An air guide structure, the air guide structure being provided at the indoor air outlet and located in the inner cavity;

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

[0025] The door body comprises:

[0026] a main body portion, the main body portion being connected to the driving mechanism and having an inner surface;

[0027] a blocking portion, the blocking portion being disposed at an edge of the inner surface and protruding from the inner surface; and

[0028] an air cavity structure, the air cavity structure being provided on the inner surface and located at the connection between the enclosure portion and the inner surface, the air cavity structure extending along a first direction, the air cavity structure being provided protruding from the inner surface, and forming a cavity therein, the air cavity structure being configured to enhance the structural strength of the main body;

[0029] The first direction is the length direction of the housing.

[0030] In some embodiments of the present application, the air conditioner is provided with an air cavity structure at the main body and the enclosure of the door body, and the main body and the enclosure are connected by the air cavity structure to enhance the connection strength between the enclosure and the main body, thereby facilitating the enhancement of the overall structural strength of the door body. Moreover, during the production process of the door body, gas can be injected into the cavity formed by the cavity wall of the air cavity structure and the main body and the enclosure. This helps to maintain the pressure of the structure at the connection between the enclosure and the main body when the main body and the enclosure are being formed, thereby avoiding, eliminating, or minimizing cracks caused by thermal expansion and contraction of the main body and the enclosure during molding, thereby enhancing the structural strength of the door body after molding.

[0031] As an optional embodiment, the driving mechanism is configured to drive the door body to move along a second direction, the inner surface has a first edge side and a second edge side along the second direction, the enclosure portion and the air cavity structure are both provided on the first edge side, and the enclosure portion is configured to abut against the casing when the door body blocks the indoor air outlet;

[0032] The second direction is the width direction of the indoor air outlet, and the second direction intersects with the first direction.

[0033] When the first edge side of the door body abuts against the housing, the air cavity structure located on the first edge side can enhance the structural strength of the first edge side, thereby preventing the door body from being damaged when the door body abuts against the housing.

[0034] As an optional embodiment, a plurality of reinforcing ribs are provided on the second edge side, and the plurality of reinforcing ribs are sequentially spaced apart along the first direction.

[0035] For example, in a sliding door, the first edge side is used to contact the casing to stop the door from sliding, and has high strength requirements. Therefore, a barrier portion and an air cavity structure are provided on the first edge side to enhance the structural strength. The second edge side is the main moving side of the door body when sliding, and the second edge side slides toward the inner cavity. In order to prevent interference with the movement of the second edge side, a barrier portion cannot be provided on the second edge side. Taking into account the structural strength of the second edge side, a plurality of reinforcing ribs are provided on the second edge side to strengthen the structural strength of the second edge side of the door body to prevent the door body from being damaged during installation and transportation.

[0036] As an optional embodiment, the cavity wall of the air cavity structure includes an inner wall surface and an outer wall surface, the outer wall surface is connected to the enclosure portion and the inner surface, and the outer wall surface is a curved surface.

[0037] By setting the cavity wall of the air cavity structure to an arc shape, the formation of sharp corners on the periphery of the air cavity structure is avoided, so that the air cavity structure forms a soft transition between the enclosure part and the main body, avoiding scratches to technicians when transporting and installing the door body.

[0038] As an optional embodiment, the main body includes a first end and a second end along the first direction, and the air cavity structure extends from the first end to the second end.

[0039] In this way, the air cavity structure can have a sufficient length so that the air cavity structure can connect the main body and the enclosure as much as possible in the first direction, thereby facilitating strengthening the overall strength of the enclosure and the main body.

[0040] As an optional implementation, the air cavity structure is integrally formed with the housing, and / or both ends of the air cavity structure in the first direction are sealed to enclose the cavity.

[0041] Such an arrangement enables the cavity of the air cavity structure to be closed at both ends in the first direction, so as to prevent the gas from escaping from both ends in the first direction when gas is introduced into the air cavity structure.

[0042] As an optional embodiment, the air cavity structure further includes a vent portion, which is provided on the cavity wall of the air cavity structure, the vent portion is communicated with the cavity, and the vent portion is configured to introduce gas into the cavity.

[0043] By setting up the ventilation part, it is possible to facilitate the introduction of gas into the cavity through the ventilation part during the production of the door body, so as to facilitate the pressure maintenance of the structure when the main body and the enclosure are formed, thereby avoiding, minimizing or eliminating cracks in the main body and the enclosure due to thermal expansion and contraction during molding, thereby improving the structural strength of the door body after molding.

[0044] As an optional embodiment, the vent portion is provided to protrude from the cavity wall, and the vent portion extends to connect with the inner surface.

[0045] That is, the ventilation part also has a certain thickness, so the ventilation part can also strengthen the structural strength of the cavity wall of the air cavity structure, thereby connecting the cavity wall and the inner surface to strengthen the connection strength between the cavity wall and the main body, which is beneficial to improving the overall structural strength of the door body.

[0046] As an optional embodiment, the ventilation portion includes multiple ventilation portions, and the multiple ventilation portions are sequentially spaced apart along the first direction.

[0047] The plurality of ventilation parts are arranged in sequence along the first direction on the door body, so that the structural strength of the door body can be enhanced by the ventilation parts at multiple positions in the first direction, which is beneficial to improving the overall structural strength of the door body.

[0048] As an optional embodiment, a protruding height of the air cavity structure on the inner surface is smaller than a protruding height of the enclosure portion on the inner surface.

[0049] In this way, the cavity wall of the air cavity structure can be prevented from protruding too high outward and exceeding the enclosure part, and the air cavity structure can be prevented from contacting the casing before the enclosure part when the door body closes the indoor air outlet, thereby causing the air cavity structure to interfere with the movement of the door body.

[0050] As an optional embodiment, the inner surface is provided with a protrusion, and the protrusion extends along the second direction;

[0051] The air guide structure is provided with a slide groove, the slide groove extends along the second direction, the protrusion is slidably connected to the slide groove, and the protrusion is configured to slide relative to the slide groove along the second direction under the drive of the driving mechanism, so that the door body slides along the second direction;

[0052] The second direction is the width direction of the indoor air outlet.

[0053] By arranging the protrusion on the inner surface of the door body, the protrusion further strengthens the structure of the door body. Moreover, the protrusion can be slidably connected to the slide groove on the air guide structure, so that when the door body slides under the drive mechanism, the protrusion can also slide relative to the slide groove.

[0054] As an optional embodiment, the protruding member includes a first protrusion and a second protrusion, the first protrusion protruding from the inner surface, the second protrusion connected to a side of the first protrusion facing away from the inner surface, the second protrusion slidably connected to the slide groove, and the second protrusion extending along the first direction so that the inner surface, the first protrusion, and the second protrusion enclose a sliding space for the side wall of the slide groove to slide;

[0055] The protruding member further includes a plurality of ribs, the ribs are located in the sliding space, and the ribs are connected between the first convex portion and the second convex portion, and the plurality of ribs are sequentially spaced along the second direction.

[0056] In this way, the protrusion uses ribs to strengthen the connection strength between the main body, the first protrusion, and the second protrusion, thereby improving the structural strength of the protrusion, so that when the second protrusion is connected to the slide groove, the second protrusion can be stably located in the slide groove, so that the two can slide effectively.

[0057] As an optional embodiment, the second protrusion has a first surface and a second surface along the thickness direction of the door body, and the first surface and the second surface are both provided with a plurality of protrusions, and the outer peripheral surface of the protrusions is an arc surface. When the second protrusion slides relative to the slide groove, the protrusions can be slidably connected to the slide groove to assist the second protrusion in sliding relative to the slide groove.

[0058] When the second convex portion slides relative to the slide groove, the arc surface of the convex column can contact the slide groove, so that the contact portion between the two is smoother when they slide relative to each other, which is conducive to the sliding of the second convex portion relative to the slide groove.

[0059] As an optional embodiment, the protruding member further includes a reinforcing plate, and the reinforcing plate is connected to at least one end of the protruding member in the second direction;

[0060] The inner surface has a first edge side and a second edge side in the second direction, and the reinforcing plate extends along the second direction so that the reinforcing plate is connected to the first edge side and / or the second edge side.

[0061] A reinforcing plate is arranged at one or both ends of the protrusion in the second direction, so that the protrusion can be connected to the first edge side and / or the second edge side of the inner surface in the second direction through the reinforcing plate, and the connection strength between the protrusion and the main body is strengthened by the reinforcing plate, and the reinforcing plate extends to thereby help improve the overall structural strength of the door body.

[0062] As an optional embodiment, the protrusion is located in the middle of the inner surface along the first direction, and the door body is provided with a first convex edge and a second convex edge at both ends along the first direction respectively. There are two driving mechanisms, and the two driving mechanisms are respectively arranged at the two ends of the indoor air outlet in the first direction, one of the driving mechanisms is installed in cooperation with the first convex edge as a hole column, and the other driving mechanism is installed in cooperation with the second convex edge as a hole column.

[0063] In this way, the door body can form a uniform three-point connection with the air guide structure and the drive mechanism at both ends and the middle portion in the first direction. When the door body is subjected to external force, the external force can be dispersed to the drive mechanism and the air guide structure through the protrusion and the first and second flanges, thereby achieving effective force distribution and facilitating the protection of the door body when subjected to external force.

[0064] As an optional embodiment, in the second direction, the width of the housing is L1, the width of the indoor air outlet is L2, and L2 ≥ L1 / 2;

[0065] Wherein, the second direction is the width direction of the door body.

[0066] Through parameter settings, the width of the indoor air outlet occupies a larger proportion of the width of the casing, which is conducive to forming a larger indoor air outlet in size and appearance, resulting in better air outlet effect and beneficial to the user experience.

[0081] 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.

[0082] In this application, terms such as "upper," "lower," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," and "horizontal" indicate positions or locations based on the positions or locations 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 to being constructed or operated in a specific orientation.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Commonly used air conditioners in households include indoor units and outdoor units. For indoor units, 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 blocking and opening of the door body for the indoor air outlet.

[0087] In the related art, the door body is relatively thin and light, and the door body is easily damaged by external forces during the use, transportation or installation of the indoor unit. To this end, ribs and sheet metal parts are usually set on the door body to enhance the thickness of the door body in order to improve the structural strength of the door body. However, although this approach enhances the structural strength of the door body, the additional structural part increases the weight of the door body, which makes it easy for the drive mechanism to cause a large load when driving the door body to move, affecting the flexibility of the door body when it moves relative to the indoor air outlet, and is not conducive to the sealing or opening effect of the indoor air outlet. In addition, the additional ribs and sheet metal parts also increase the production cost. However, if the weight of the door body is reduced, it is easy to cause the structural strength of the door body to be insufficient, increasing the risk of damage to the door body.

[0088] Therefore, how to balance the door weight and structural strength of the air conditioner indoor unit has become one of the important research topics in indoor unit design.

[0089] In response to the above problems, this application discloses an air conditioner that improves the door structure by providing an air cavity structure, thereby increasing the door structural strength and reducing the number of ribs and sheet metal parts on the door. This not only helps reduce the weight of the door, but also helps reduce production costs.

[0090] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0091] 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.

[0092] Please also see Figures 2 to 4In some embodiments, the indoor unit 100 includes a casing 1 having an inner cavity 1 a , and the casing 1 is provided with an indoor air outlet 1 c and an indoor air inlet 1 b , and the indoor air outlet 1 c and the indoor air inlet 1 b are connected to the inner cavity 1 a .

[0093] In some embodiments, the indoor unit 100 includes a door body 2 , which is provided at the indoor air outlet 1 c , and is used to cover or open the indoor air outlet 1 c on the casing 1 .

[0094] In some embodiments, the indoor unit 100 includes a heat exchange volute (not shown).

[0095] In some embodiments, the heat exchange volute is disposed in the inner cavity 1a.

[0096] In some embodiments, the indoor unit 100 includes an indoor heat exchanger 3 .

[0097] 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.

[0098] In some embodiments, the indoor unit 100 includes a heat exchange blower (not shown).

[0099] 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.

[0100] Driven by the heat exchange fan, the indoor air enters the heat exchange volute from the heat exchange indoor air inlet 1b 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 1c.

[0101] 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.

[0102] 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, and then enter the rotor. The rotor then acts to blow the air out of the indoor air outlet 1c.

[0103] In some embodiments, the indoor unit 100 includes an air guide structure 4 , which is provided at the indoor air outlet 1 c and located in the inner cavity 1 a .

[0104] Optionally, the air guide structure 4 includes an air guide plate 41, which is located at the indoor air outlet 1c. The air guide plate 41 can be rotated along the height direction of the indoor air outlet 1c and connected to the air outlet frame. The air guide plate 41 can guide the wind direction of the indoor air outlet 1c, so that the vertical air conditioner has a larger blowing range.

[0105] 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 1c.

[0106] In some embodiments, the indoor unit 100 includes a driving mechanism (not shown), which is disposed in the inner cavity 1a. The driving mechanism is configured to drive the door body 2 to move so that the door body 2 blocks or opens the indoor air outlet 1c.

[0107] 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.

[0108] In some embodiments, the power source may be, for example, an electric motor.

[0109] For example, the drive mechanism can drive the door body 2 to slide relative to the indoor air outlet 1c, or can drive the door body 2 to rotate relative to the indoor air outlet 1c to open or block the indoor air outlet 1c. 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.

[0110] In some embodiments, an air conditioner outdoor unit includes an indoor casing, an outdoor heat exchanger, and an outdoor fan.

[0111] In some embodiments, an outdoor accommodation space is provided in the housing, wherein the outdoor fan and the outdoor heat exchanger are provided in the outdoor accommodation space.

[0112] In some embodiments, the housing is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are in communication with the outdoor receiving space. The outdoor air inlet is used to introduce outdoor air into the outdoor receiving space, and the outdoor air outlet is used to draw air from the outdoor receiving space to the outside of the outdoor receiving space.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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 cycle, the vertical type can regulate the temperature of the indoor space.

[0121] 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.

[0122] See Figure 4 In some embodiments, the door body 2 includes a main body 21 and a surrounding portion 22. The main body 21 is connected to the driving mechanism. The main body 21 has an inner surface 21a. The surrounding portion 22 is arranged at the edge of the inner surface 21a and protrudes from the inner surface 21a.

[0123] Optionally, the main body 21 can be a plate, and the enclosure 22 can be a convex edge protruding from the edge of the plate. The enclosure 22 can be set at each edge of the main body 21, or only at one edge of the door body 2.

[0124] Taking the door body 2 as a sliding door as an example, for example, when the door body 2 slides in the second direction to block the indoor air outlet 1c, the drive mechanism drives the door body 2 to slide in the second direction. The door body 2 stops sliding due to the contact between the edge blocking portion 22 and the housing 1, thereby blocking the indoor air outlet 1c. In this way, the main body 21 is prevented from directly contacting the housing 1 during the movement of the door body 2, thereby protecting the main body 21.

[0125] In some embodiments, the door body 2 includes an air cavity structure 23, which is provided on the inner surface 21a and located at the connection between the enclosure portion 22 and the inner surface 21a. The air cavity structure 23 protrudes from the inner surface 21a and extends along the first direction on the inner surface 21a.

[0126] In one example, the air cavity structure 23 includes a cavity wall 231, which is interconnected with the enclosure 22 and the inner surface 21a to enclose and form a cavity 232, so that the air cavity structure 23 is integrally arranged with the enclosure 22 and the inner surface 21a.

[0127] In another example, an air cavity structure 23 is separately provided at the connection between the inner surface 21 a and the enclosure portion 22 . The air cavity structure 23 has a cavity 232 formed therein, so that the air cavity structure 23 is configured to enhance the structural strength of the main body 21 .

[0128] In some embodiments of the present application, the air conditioner is provided with an air cavity structure 23 at the main body 21 and the enclosure 22 of the door body 2. The main body 21 and the enclosure 22 are connected via the air cavity structure 23 to enhance the connection strength between the enclosure 22 and the main body 21, thereby facilitating the enhancement of the overall structural strength of the door body 2. Furthermore, during the production process of the door body 2, gas can be injected into the cavity 232 of the air cavity structure 23. This helps maintain the pressure of the main body 21 and the enclosure 22 during molding, eliminates cracks caused by thermal expansion and contraction of the main body 21 and the enclosure 22 during molding, and thus enhances the structural strength of the door body 2 after molding.

[0129] It should be noted that in Figure 1 or Figure 2 In the example shown, the direction indicated by X is the first direction, which can be the length of the housing 1, the length of the door 2, or the length of the indoor air outlet 1c. In a wall-mounted indoor unit 100, the length of the housing 1 is the length of the entire unit. In a floor-standing indoor unit 100, the length of the housing 1 is the height of the entire unit.

[0130] In some embodiments, the cavity wall 231 of the air cavity structure 23 includes an inner wall surface 231 a and an outer wall surface 231 b .

[0131] It can be understood that no matter the cavity wall 231 of the air cavity structure 23, the enclosure portion 22 and the inner surface 21a form the cavity 232 or the cavity wall 231 of the air cavity structure 23 alone forms the cavity 232, the cavity wall 231 has an inner wall surface 231a facing the cavity 232 and an outer wall surface 231b away from the cavity 232.

[0132] Optionally, the outer wall surface 231b of the cavity wall 231 of the air cavity structure 23 is a curved surface, and the outer wall surface 231b is connected to the enclosure portion 22 and the inner surface 21a. In this way, by setting the cavity wall 231 of the air cavity structure 23 as a curved surface, the outer periphery of the air cavity structure 23 is prevented from forming sharp corners, so that the air cavity structure 23 forms a soft transition between the enclosure portion 22 and the main body 21, thereby preventing technicians from scratching the door body 2 during transportation and installation.

[0133] In some embodiments, the driving mechanism is configured to drive the door body 2 to move along the second direction. Taking the door body 2 as a sliding door as an example, illustratively, the door body 2 slides along the second direction under the drive of the driving mechanism.

[0134] It should be noted that in Figure 1 or Figure 2 In the example shown, the direction indicated by Y is the second direction, which can be the width direction of the indoor air outlet 1c or the width direction of the door body 2. Figure 1 or Figure 2 In the example shown, the second direction intersects the first direction.

[0135] Optionally, the inner surface 21a of the main body 21 has a first edge side 211 and a second edge side 212 along the second direction, the enclosure 22 and the air cavity structure 23 are both arranged on the first edge side 211, and the enclosure 22 is configured to abut against the casing 1 when the door body 2 blocks the indoor air outlet 1c.

[0136] Taking the door body 2 as a sliding door, in one example, when the door body 2 slides in the second direction to block the indoor air outlet 1c, the drive mechanism drives the door body 2 to slide in the second direction. The door body 2 stops sliding due to the contact between the blocking portion 22 on the first edge side 211 and the housing 1, thereby blocking the indoor air outlet 1c. In this way, when the door body 2 slides in the second direction to open the indoor air outlet 1c, the door body 2 slides from the first edge side 211 to the second edge side 212 and is hidden in the housing 1.

[0137] In another example, when the door body 2 slides in the second direction to block the indoor air outlet 1c, the drive mechanism drives the door body 2 to slide in the second direction. The second edge side 212 is provided with a blocking portion 22 and an air cavity structure 23. The door body 2 stops sliding due to the abutment between the blocking portion 22 on the second edge side 212 and the housing 1, thereby blocking the indoor air outlet 1c. In this way, when the door body 2 slides in the second direction to open the indoor air outlet 1c, the door body 2 slides from the second edge side 212 to the first edge side 211 and is hidden in the housing 1.

[0138] In this way, the enclosure portion 22 and the air cavity structure 23 set on the main body 21 are conducive to enhancing the structural strength of the main body 21. Regardless of whether the enclosure portion 22 is set on the first edge side 211 and / or the second edge side 212, the enclosure portion 22 can be abutted against the casing 1, and then the air cavity structure 23 can support the enclosure portion 22, thereby preventing damage to the door body 2.

[0139] See Figure 5 and Figure 6 Optionally, when the inner surface 21a of the main body 21 is provided with the enclosing portion 22 and the air cavity structure 23 on the first edge side 211 or the second edge side 212 in the second direction, the other edge side is not provided with the enclosing portion 22 and the air cavity structure 23. A plurality of reinforcing ribs 24 may be provided on the edge side where the enclosing portion 22 and the air cavity structure 23 are not provided, thereby reducing the production difficulty and improving the structural strength of the door body 2.

[0140] Taking the door body 2 as a sliding door as an example, for example, in the sliding door, the first edge side 211 is used to contact the casing 1 to stop the door body 2 from sliding. The strength requirement for the first edge side 211 is relatively high, so the first edge side 211 is provided with a blocking portion 22 and an air cavity structure 23. The second edge side 212 is the main moving side of the door body 2 when sliding, and the second edge side 212 slides toward the inner cavity 1a. In order to prevent interference with the movement of the second edge side 212, the blocking portion 22 cannot be provided on the second edge side 212. Taking into account the structural strength problem of the second edge side 212, a plurality of reinforcing ribs 24 are provided on the second edge side 212, so that the structural strength of the second edge side 212 of the door body 2 is strengthened to prevent the door body 2 from being damaged during installation and transportation.

[0141] In some examples, the first edge side 211 is provided with a blocking portion 22 and an air cavity structure 23 , and the second edge side 212 is provided with a plurality of reinforcing ribs 24 , which are arranged in sequence and spaced apart along the first direction to strengthen the structural strength of the main body 21 .

[0142] In other examples, the second edge side 212 is provided with a blocking portion 22 and an air cavity structure 23 , and the first edge side 211 is provided with a plurality of reinforcing ribs 24 , which are arranged in sequence and spaced apart along the first direction to strengthen the structural strength of the main body 21 .

[0143] In this way, by respectively providing the air cavity structure 23 and the reinforcing ribs 24 on the two edge sides of the main body 21 , the overall structural strength of the door body 2 is enhanced to prevent the door body 2 from being damaged during installation and transportation.

[0144] In some embodiments, the main body 21 includes a first end 21 b and a second end 21 c in a first direction, and the air cavity structure 23 extends from the first end 21 b to the second end 21 c.

[0145] Exemplarily, when the air cavity structure 23 extends from the first end 21b to the second end 21c, the air cavity structure 23 can extend to no longer contact the second end 21c, so that the air cavity structure 23 does not completely cover the edge side of the door body 2 in the first direction, or the air cavity structure 23 can extend to contact the second end 21c, so that the air cavity structure 23 can completely cover the edge side of the door body 2 in the first direction.

[0146] In one example, the air cavity structure 23 is provided on the first edge side 211 , and the air cavity structure 23 extends on the first edge side 211 so that the air cavity structure 23 can cover the entire first edge side 211 , thereby effectively enhancing the structural strength of the entire first edge side 211 .

[0147] In one example, the air cavity structure 23 is provided on the second edge side 212 , and the air cavity structure 23 extends on the second edge side 212 so that the air cavity structure 23 can cover the entire second edge side 212 , thereby effectively enhancing the structural strength of the entire second edge side 212 .

[0148] In this way, when the air cavity structure 23 is disposed on and covers any edge side of the main body 21 , the structural strength of the main body 21 can be effectively enhanced.

[0149] Taking the production of the door body 2 of the present application as an example, the door body 2 is an injection-molded door body 2. When the door body 2 is injection-molded, gas is injected into the connection between the main body 21 and the enclosure 22 of the door body 2 to form an air cavity structure 23 at the connection. The air cavity structure 23 is used to strengthen the connection strength between the enclosure 22 and the main body 21.

[0150] Considering that the air cavity structure 23 can flow gas and extend along the first direction, in some embodiments, both ends of the air cavity structure 23 in the first direction are sealed to enclose the cavity 232 inside the air cavity structure 23. In this way, when the air cavity structure 23 is formed, it is convenient for gas to flow along the first direction after entering the cavity 232, so that the cavity structure extends along the first direction.

[0151] Optionally, the closed shapes of the seals at both ends of the air cavity structure 23 in the first direction may be a gradually narrowing shape or a truncated seal shape, which is not specifically limited in this application.

[0152] See Figure 7 Taking the production of the door body 2 of the present application as an example, when the air cavity structure 23 is injected with gas for molding, a vent 233 is left for letting in gas. In some embodiments, the air cavity structure 23 further includes a vent 233, which is provided on the cavity wall 231 of the air cavity structure 23. The vent 233 is in communication with the cavity 232, and the vent 233 is configured to let in gas into the cavity 232. In this way, when the air cavity structure 23 is molded, gas is introduced into the cavity 232 through the vent 233, so that the main body 21 and the surrounding part 22 can be pressurized during molding, thereby eliminating cracks caused by thermal expansion and contraction of the main body 21 and the surrounding part 22 during molding, thereby improving the structural strength of the door body 2 after molding.

[0153] Optionally, the vent portion 233 may be a solid columnar structure connected to the cavity wall 231 , or an opening directly opened on the cavity wall 231 .

[0154] Taking the example of a solid columnar structure of vent 233, vent 233 can optionally be arranged to protrude from cavity wall 231 and extend to connect with inner surface 21a. Specifically, when the columnar structure of vent 233 is formed, a portion of vent 233 connects to cavity wall 231, allowing vent 233 to communicate with cavity 232, while a portion of vent 233 connects to inner surface 21a. In this way, vent 233 connects cavity wall 231 to inner surface 21a, thereby increasing the connection strength between cavity wall 231 and inner surface 21a, which helps improve the overall structural strength of door body 2.

[0155] Optionally, when the vent portion 233 is a columnar structure, the vent portion 233 may be in a square column shape, a cylindrical shape, etc., which is not specifically limited in this application.

[0156] Optionally, taking the vent portion 233 as a solid columnar structure as an example, in order to further improve the structural strength of the door body 2 in the first direction, the vent portion 233 includes multiple vent portions 233, and the multiple vent portions 233 are sequentially spaced along the first direction.

[0157] Specifically, there can be two, three, four, etc. vents 233. Setting at least two is beneficial to improving the structural strength of the door body 2 in the first direction. Setting a maximum of four vents 233 can avoid too many physical structures of the vents 233 causing an increase in the weight of the door body 2.

[0158] In some embodiments, the protrusion height of the air cavity structure 23 on the inner surface 21a is less than the protrusion height of the enclosure portion 22 on the inner surface 21a. Taking the production of the door body 2 of the present application as an example, for example, when gas is introduced into the connection between the enclosure portion 22 and the main body 21, the unformed injection molding material at the connection protrudes relative to the inner surface 21a of the main body 21 under the support of the injected gas, and forms the air cavity structure 23 after solidification. In order to prevent the unformed injection molding material from protruding too high on the inner surface 21a, the molding height of the air cavity structure 23 is controlled.

[0159] In this way, the cavity wall 231 of the air cavity structure 23 is prevented from protruding outward too high and exceeding the enclosure 22, so as to avoid the air cavity structure 23 contacting the casing 1 before the enclosure 22 when the door body 2 closes the indoor air outlet 1c.

[0160] This application not only considers the influence of the structure of the door body 2 on the structural strength of the door body 2, but also considers the influence of the connection method of the door body 2 at the indoor air outlet 1c on the structural strength of the door body 2 when the door body 2 is installed at the indoor air outlet 1c.

[0161] Please see again Figure 5 In some embodiments, the inner surface 21a of the main body 21 is provided with a protrusion 25, and the protrusion 25 extends along the second direction. For example, when the protrusion 25 is provided on the inner surface 21a along the second direction, the protrusion 25 can strengthen the structural strength of the main body 21 along the second direction.

[0162] Optionally, taking the door body 2 of the present application as a sliding door as an example, see Figure 8 The air guide structure 4 includes an air guide plate 41 and a slide 42 connected to the air guide plate 41. The slide 42 extends in the second direction corresponding to the protrusion 25. The protrusion 25 is slidably connected to the slide 42. The protrusion 25 is configured to slide relative to the slide 42 in the second direction under the drive mechanism, thereby causing the door body 2 to slide in the second direction. In other words, when the drive mechanism drives the door body 2 to slide in the second direction, the protrusion 25 can move with the door body 2, thereby causing the protrusion 25 to slide within the slide 42.

[0163] Exemplarily, the protruding member 25 may be a slide rail that cooperates with the slide groove 42 so that the slide rail slides in the slide groove 42 .

[0164] Exemplarily, the protrusion 25 can be a ball or roller, etc. When the ball or roller slides in the slide groove 42, the ball can roll relative to the slide groove 42, so that the sliding is converted into rolling, which is more flexible and is conducive to assisting the door body 2 to slide along the second direction.

[0165] Since the door body 2 is connected to the air guide structure 4 through the protrusion 25, part of the external force applied to the door body 2 can be transmitted to the air guide structure 4 through the protrusion 25 to disperse the force applied to the door body 2, thereby preventing the door body 2 from being damaged when subjected to external force.

[0166] See Figure 9 In some embodiments, the protrusion 25 includes a first protrusion 251 and a second protrusion 252. The first protrusion 251 protrudes from the inner surface 21a, and the first protrusion 251 is connected between the inner surface 21a and the second protrusion 252. The second protrusion 252 can be slidably connected to the slide groove 42. The second protrusion 252 extends along the first direction so that the inner surface 21a, the first protrusion 251, and the second protrusion 252 enclose a sliding space 25a.

[0167] Exemplarily, when the second protrusion 252 slides relative to the slide groove 42, a side wall of the slide groove 42 is located in the sliding space 25a, so that when the slide groove 42 slides relative to the second protrusion 252, a side wall of the slide groove 42 slides in the sliding space 25a.

[0168] Optionally, the first protrusion 251 and the second protrusion 252 can both be strip-shaped plates, and the first protrusion 251 and the second protrusion 252 extend along the second direction to enhance the structural strength of the door body 2 in the second direction.

[0169] In some embodiments, the protrusion 25 includes a rib 253 located in the sliding space 25a and connected between the first protrusion 251 and the second protrusion 252. Thus, the rib 253 strengthens the connection strength and structural strength between the first protrusion 251 and the second protrusion 252.

[0170] In some embodiments, there are multiple ribs 253 , and the multiple ribs 253 are sequentially spaced apart along the second direction, thereby further strengthening the connection strength and structural strength of the first protrusion 251 and the second protrusion 252 .

[0171] See Figure 10In order to improve the sliding effect of the second protrusion 252 in the slide groove 42, taking the second protrusion 252 as a slide rail as an example, in some embodiments, the second protrusion 252 has a first surface 252a and a second surface 252b along the thickness direction of the door body 2, and the first surface 252a and the second surface 252b are both provided with a plurality of protrusions 252c, and the outer peripheral surface of the protrusion 252c is an arc surface. When the second protrusion 252 slides relative to the slide groove 42, the protrusion 252c can be slidably connected to the slide groove 42 to assist the second protrusion to slide relative to the slide groove 42.

[0172] It is understood that the contact between the first surface 252a and the second surface 252b of the second protrusion 252 and the chute 42 is between two planes, resulting in a relatively large sliding resistance. When the protrusion 252c contacts the chute 42, the curved surface contacts the flat surface, which reduces the contact area between the two, thereby reducing the sliding resistance between the two and further improving the sliding effect of the second protrusion 252 within the chute 42.

[0173] In some embodiments, the protrusion 25 further includes a reinforcing plate 254 connected to at least one end of the protrusion 25 in the second direction. Providing the reinforcing plate 254 at one or both ends of the protrusion 25 in the second direction strengthens the structural strength of the protrusion 25, thereby preventing damage to the protrusion 25 and failure of the connection with the chute 42.

[0174] In some embodiments, the reinforcing plate 254 extends along the second direction so as to be connected to the first edge side 211 and / or the second edge side 212 of the inner surface 21a. The reinforcing plate 254 strengthens the connection strength between the protrusion 25 and the main body 21, thereby improving the overall structural strength of the door body 2.

[0175] In some embodiments, the protrusion 25 is located in the middle of the inner surface 21a along the first direction. By setting the protrusion 25 in the middle of the inner surface 21a, the structural arrangement of the door body 2 is more balanced, preventing the uneven weight of the door body 2 from affecting the structural strength of the door body 2.

[0176] In addition, a protrusion 25 is provided in the middle of the door body 2, and an air cavity structure 23 and a reinforcing rib 24 are respectively provided on the two edge sides in the second direction, so that the structure of the door body 2 at three positions is strengthened, which is beneficial to improving the overall structural strength of the door body 2.

[0177] See Figure 5 Optionally, the door body 2 is provided with a first flange 26 and a second flange 27 at both ends along the first direction, and there are two driving mechanisms, which are respectively arranged at the two ends of the indoor air outlet 1c in the first direction, one of which is installed in conjunction with the first flange 26 as a hole column, and the other driving mechanism is installed in conjunction with the second flange 27 as a hole column.

[0178] For example, when the first flange 26 is installed in cooperation with one of the drive mechanism hole columns, the first flange 26 can be provided with a hole portion 26a and the drive mechanism can be provided with a column portion, or the first flange 26 can be provided with a column portion and the drive mechanism can be provided with a hole portion 26a.

[0179] For example, when the second flange 27 is installed in cooperation with another drive mechanism hole column, the second flange 27 can be provided with a hole portion 26a and the drive mechanism can be provided with a column portion, or the second flange 27 can be provided with a column portion and the drive mechanism can be provided with a hole portion 26a.

[0180] Optionally, along the first direction, the first flange 26 and the second flange 27 are connected to the two drive mechanisms, and the protrusion 25 on the inner surface 21a is connected to the slide groove 42 on the air guide structure 4. In this way, the door body 2 forms a three-point connection. When the door body 2 is subjected to external force, the external force can be transmitted from the first flange 26, the second flange 27 and the protrusion 25 to the drive mechanism and the air guide structure 4, thereby preventing damage to the door body 2.

[0181] Considering the increasing demand for indoor unit with 100mm air outlet, please refer to Figure 11 In some embodiments, in the second direction, the width of the casing 1 is L1, the width of the indoor air outlet 1c is L2, and L2 ≥ L1 / 2.

[0182] This application takes into account that if the size of the indoor air outlet 1c is too large, it will cause the size of the door body 2 to be too large, which may cause the weight of the door body 2 to be too heavy, which is not conducive to the driving of the driving mechanism. If the size of the indoor air outlet 1c is too small, it may cause the indoor air outlet 1c to have insufficient air volume and poor air outlet effect, affecting the user experience. Therefore, this application sets the proportion of the indoor air outlet 1c to be greater than or equal to half of the casing 1, so that the size of the indoor air outlet 1c is increased while the proportion of the visual effect of the indoor air outlet 1c on the front appearance is greater than that of the casing 1. In this way, not only the indoor air outlet 1c is larger in structure, but the indoor air outlet 1c also appears larger in appearance, which is conducive to increasing the air volume, improving the user experience, and meeting the user's demand for large air outlets.

[0183] As the size of the indoor air outlet 1c increases, the size of the door body 2 used to shield the indoor air outlet 1c also increases, and the weight of the door body 2 increases. If reinforcing ribs 24 or sheet metal parts are used to enhance the structural strength of the door body 2, the weight of the door body 2 will further increase. However, the door body 2 disclosed in this application is provided with an air cavity structure 23 to enhance the structural strength of the door body 2. Even if the size of the door body 2 increases, it is beneficial to reduce the number of reinforcing ribs 24 and sheet metal parts on the door body 2, thereby avoiding further increase in the weight of the door body 2 and facilitating better movement of the door body 2 in the second direction under the drive of the drive mechanism.

[0184] The above is a detailed introduction to the air conditioner disclosed in the embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the air conditioner of the present application and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
