Description

Technical Field

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

[0002] With the improvement of living standards, air conditioners have become an indispensable household appliance. Vertical air conditioners, which can meet the heating and cooling needs of large areas, are often installed in places such as living rooms and offices. Vertical air conditioners typically consist of an indoor unit and an outdoor unit. The indoor unit consists of a housing and an air outlet frame. The air outlet frame is connected to the housing and has an air outlet on the housing to blow air into the room.

[0003] In the prior art, vertical air conditioner indoor units typically feature a sliding door at the air outlet, which slides to cover or open the air outlet. To prevent the housing from deforming or collapsing, which could interfere with the movement of the door, sheet metal components are typically installed inside the housing to increase strength. However, this approach requires separate assembly, increasing the number of parts, resulting in low assembly efficiency and increased costs. Utility Model Content

[0004] The embodiment of the present application discloses a vertical air conditioner, which can effectively strengthen the strength of the casing to prevent deformation, while also improving the assembly efficiency of the casing and reducing costs.

[0005] In order to achieve the above-mentioned objectives, the present application discloses a vertical air conditioner, comprising:

[0006] Indoor unit, the indoor unit includes

[0007] a casing having an interior space and provided with an air outlet communicating with the interior space;

[0008] an air outlet frame, the air outlet frame being located in the internal space and connected to the housing to form a sliding space between the air outlet frame and the housing that is connected to the internal space;

[0009] A sliding door structure, the sliding door structure being slidably disposed on the air outlet;

[0010] The sliding door structure comprises:

[0011] A driving mechanism, the driving mechanism being arranged on the air outlet frame;

[0012] a door body, the door body being connected to the driving mechanism, and the door body being driven by the driving mechanism to slide in the sliding space to cover or open the air outlet;

[0013] The casing is provided with an air cavity structure protruding toward the internal space. The air cavity structure is located on the sliding path of the door body. The air cavity structure extends along the height direction of the casing. The air cavity structure is integrally formed with the casing, and a cavity is formed inside the air cavity structure.

[0014] The present application also provides a vertical air conditioner, comprising:

[0015] Indoor unit, the indoor unit includes

[0016] a casing having an interior space and provided with an air outlet communicating with the interior space;

[0017] an air outlet frame, the air outlet frame being located in the internal space and connected to the housing to form a sliding space between the air outlet frame and the housing that is connected to the internal space;

[0018] A sliding door structure, the sliding door structure being slidably disposed on the air outlet;

[0019] The sliding door structure comprises:

[0020] A driving mechanism, the driving mechanism being arranged on the air outlet frame;

[0021] a door body, the door body being connected to the driving mechanism, and the door body being driven by the driving mechanism to slide in the sliding space to cover or open the air outlet;

[0022] The casing is provided with an air cavity structure protruding toward the internal space, the air cavity structure is located on the sliding path of the door body, the air cavity structure extends along the height direction of the casing, the air cavity structure includes a side wall portion, the side wall portion is enclosed and connected to the casing to form a cavity therebetween, the side wall portion is integrally formed with the casing, and the air cavity structure is configured to strengthen the strength of the casing.

[0023] The vertical air conditioner provided by the present application is provided with an air cavity structure protruding toward the internal space on the casing, and the air cavity structure is located on the sliding path of the door body to enhance the strength of the casing corresponding to the sliding space. Compared with the method of additionally providing sheet metal parts to improve the strength of the casing in the related art, the present application utilizes an air cavity structure with a cavity formed inside that is integrally formed with the casing, which can reduce, eliminate or minimize surface defects such as warping, deformation, and collapse caused by internal residual stress during the molding process of the casing, thereby strengthening the structural strength of the casing itself, and further preventing the deformation of the casing from interfering with the door body in movement. In addition, the air cavity structure is integrally formed with the casing, which simplifies the number of parts of the casing, does not require additional assembly, improves the assembly efficiency of the casing, and can save materials, thereby reducing production costs.

[0024] In some embodiments of the present application, the housing includes:

[0025] First panel;

[0026] a second panel, wherein the air outlet is constructed between the second panel and the first panel, and the sliding space is formed between the first panel and the air outlet frame;

[0027] The air cavity structure includes a first air cavity, the first panel is provided with the first air cavity, and the second panel is connected to the air outlet frame.

[0028] By forming a sliding space between the first panel and the air outlet frame for the door to slide, that is, the door slides toward one side of the housing, compared to the method of sliding the door on both sides, there is no need to split the door into two parts, which can simplify the door structure and facilitate the assembly of the entire sliding door structure. When the door is closed, no gap is formed on the exterior surface of the vertical air conditioner due to the closure of the two parts of the door, thereby improving the aesthetics of the vertical air conditioner. At the same time, forming this sliding space on one side of the housing not only allows the door to slide to open or cover the air outlet, but also does not excessively occupy the internal space of the housing, thereby facilitating the arrangement of internal components.

[0029] In some embodiments of the present application, the first panel has a first edge close to the air outlet, the first edge extends along the height direction of the housing, and the first air cavity is provided at the first edge.

[0030] With the sliding space formed between the first panel and the air outlet frame, most of the first panel is suspended in the air, making it very susceptible to inward deformation. Furthermore, the edges of the first panel, being relatively weak, are more susceptible to damage or deformation. Therefore, by providing a first air cavity at the first edge of the first panel near the air outlet, the structural strength and stability of the first panel can be more effectively improved, making it less susceptible to deformation and thus preventing movement interference with the door body. Furthermore, the gap between the first panel and the door body when the air outlet is blocked can be effectively maintained in the vertical direction, thereby forming a uniform gap from top to bottom.

[0031] In some embodiments of the present application, the first edge is provided with a first rib protruding toward the interior space, the first rib extending from the top of the air outlet to the bottom of the air outlet along the height direction of the housing, and the first rib is configured to block a gap between the first panel and the door body when the door body blocks the air outlet;

[0032] The first air cavity is located at the connection between the first rib and the first edge.

[0033] By arranging a first rib protruding toward the interior space on the first edge, when the door body blocks the air outlet, the gap between the first panel of the casing and the door body can be made smaller, and no large black seam can be seen between the first panel and the door body in appearance, thereby improving the appearance of the vertical air conditioner.

[0034] In some embodiments of the present application, the second panel has a second edge close to the air outlet, the second edge extends along the height direction of the housing, and the second edge is provided with a second rib protruding toward the interior space, and the second rib is configured to cover the gap between the second panel and the door body when the door body covers the air outlet;

[0035] The air cavity structure further includes a second air cavity, which is provided at the connection between the second rib and the second edge;

[0036] The second air cavity is provided with a first clamping portion, the air outlet frame is provided with a second clamping portion, and the first clamping portion and the second clamping portion are cooperatively connected.

[0037] By providing a second rib protruding toward the interior space on the second edge of the second panel, the gap between the second panel and the door body is reduced when the door body blocks the air outlet, eliminating a large black gap between the second panel and the door body, thereby further improving the aesthetics of the vertical air conditioner. Furthermore, by providing a second air cavity at the intersection of the second rib and the second edge, the structural strength of the second panel is increased, thereby preventing deformation or collapse of the second panel, which could affect the reliability of its installation.

[0038] On the basis that the door body can slide toward one side of the first panel to achieve blocking or opening the air outlet, the second panel does not need to reserve sliding space. Based on this, a first clamping portion is set on the second edge of the second panel, which cooperates with the second clamping portion set on the air outlet frame, and the first clamping portion and the second air cavity are combined. This can greatly enhance the strength of the panel itself while improving the stability of the connection of the second panel. The setting of the second air cavity increases the wall thickness at the second edge. On this basis, the first clamping portion is set to provide it with better bearing capacity, thereby reducing the possibility of the first clamping portion breaking due to too thin a wall thickness.

[0039] In addition, when the second edge is connected to the air outlet frame by the cooperation of the first clamping portion and the second clamping portion, a second retaining edge is also protruded from the second edge, which can absorb and disperse the external force acting on the second edge to a certain extent, thereby improving the bearing capacity of the second panel.

[0040] In some embodiments of the present application, the air cavity structure extends from the top end of the air outlet to the bottom end of the air outlet; and / or,

[0041] The air cavity structure is formed with a plurality of air nozzles protruding toward the internal space, and the air nozzles are configured to inject gas into the interior of the air cavity structure to form the cavity. The plurality of air nozzles are spaced apart along an extension direction of the air cavity structure.

[0042] The air cavity structure extends from the top of the air outlet to the bottom of the air outlet, that is, the entire air cavity structure is arranged in the length direction of the air outlet, and its extension length is roughly the same as the length of the air outlet, which can greatly enhance the strength of the casing.

[0043] The air cavity structure can be formed by injecting gas through an air nozzle, and the air nozzle protrudes from the outer surface of the air cavity structure. In this way, the wall thickness of the air cavity structure can be thicker, thereby more effectively improving the strength of the casing.

[0044] In some embodiments of the present application, the air cavity structure is a cylindrical convex strip, the diameter of the air cavity structure is D1, the wall thickness of the housing is D2, and the ratio of D1 / D2 satisfies: D1 / D2≥1.6, and / or, D1 / D2≤4.

[0045] Meeting this condition allows the diameter of the air cavity structure to be relatively large while maintaining the same casing wall thickness. This allows the high-pressure gas in the cavity to flow more easily, thereby further promoting the filling of the casing with molten plastic and improving the casing molding quality. At the same time, the diameter of the air cavity structure can be controlled to prevent the cavity from being too large, thereby minimizing problems such as casing dents, warping, and shrinkage, thereby ensuring optimal casing molding quality and structural strength.

[0046] In some embodiments of the present application, D1 satisfies: D1 ≥ 5 mm, and / or, D1 ≤ 10 mm; and / or,

[0047] D2 satisfies: D2 ≥ 2.5 mm, and / or, D2 ≤ 3 mm.

[0048] D1 satisfies the above relationship, so that the cavity of the air cavity structure will not be too small, thereby providing a good channel for the gas, which is beneficial to the flow of the plastic melt of the casing and improves the molding quality of the casing. At the same time, the diameter of the air cavity structure will not be too large, and the air cavity structure will not be too protruding to affect the movement of the door body 32.

[0049] When D2 satisfies the aforementioned relationship, the casing wall thickness is minimized, preventing uneven flow of the casing's molten plastic within the mold. This maintains uniformity and consistency in the finished casing, while also ensuring the required strength of the molded casing. Furthermore, this ensures smooth flow of the casing's molten plastic, shortening cooling time and minimizing surface defects such as shrinkage and bubbles. This results in improved molding quality and ideal structural strength.

[0050] In some embodiments of the present application, the internal space includes a first space and a second space along the height direction of the housing, the second space is located below the first space, and the air outlet frame is located in the first space;

[0051] The housing is provided with a maintenance port, the maintenance port and the air outlet are spaced apart in the height direction of the housing, a partition is constructed between the maintenance port and the air outlet, the maintenance port is located below the air outlet and is connected to the second space;

[0052] The indoor unit further includes:

[0053] an electrical appliance box, the electrical appliance box being located in the second space and disposed near the maintenance port;

[0054] A maintenance panel is detachably connected to the housing to cover the maintenance port.

[0055] By forming a separate maintenance port in the housing and placing the electrical box near the maintenance port, when the electrical box needs to be repaired, the electrical box can be repaired or replaced by simply removing the maintenance panel that corresponds to the electrical box without having to disassemble the entire housing, simplifying the maintenance process and thus improving the convenience of maintenance. In addition, it can be understood that the air outlet is located on the main exterior surface of the housing that is visible to the user, and the maintenance port is set below the air outlet, and the maintenance panel is used to cover the maintenance port. The maintenance panel is integrated with the housing of the vertical air conditioner, so that maintenance can be carried out directly when necessary without having to move the entire vertical air conditioner significantly, which can further improve the convenience of maintenance of the vertical air conditioner.

[0056] In some embodiments of the present application, the maintenance panel is provided with a first connection portion, and the housing is provided with a second connection portion, and the first connection portion and the second connection portion are configured to allow a fastener to pass through;

[0057] The maintenance panel is provided with a third clamping portion, the housing is provided with a fourth clamping portion, and the third clamping portion is cooperatively connected with the fourth clamping portion.

[0058] This arrangement allows the maintenance panel to be more firmly fixed to the casing, thereby improving the stability of the maintenance panel connection.

[0059] In some embodiments of the present application, the partition portion has a first inner wall surface, the second connecting portion is protruded from the first inner wall surface, and the second connecting portion is provided with a through hole penetrating along the height direction of the housing;

[0060] The maintenance panel has a second inner wall surface, the first connecting portion is protruding from the second inner wall surface, and the fastener is configured to pass through the second connecting portion and connect with the first connecting portion along the height direction of the housing;

[0061] The third clamping portion is provided on both sides of the maintenance panel in the width direction of the air outlet.

[0062] By arranging the snap-fitting portions on both sides of the maintenance panel and arranging the first connection portion connected by the fastener at the end of the maintenance panel, the connection points of the maintenance panel can be more evenly distributed, thereby making the connection of the maintenance panel more stable. In addition, the first connection portion requiring fastener connection is arranged at the end of the maintenance panel near the air outlet, and the second connection portion is arranged on the partition between the air outlet and the maintenance port. On the one hand, the connection portion can be hidden inside the housing so that the fastener is not exposed on the exterior surface, thereby improving the appearance of the housing. On the other hand, the fastener can be connected to the connection portion in a vertical direction. When the fastener is removed, maintenance can be carried out from the air outlet. This arrangement position is more reasonable and more convenient for maintenance and disassembly.

[0063] In some embodiments of the present application, the driving mechanism is disposed at the partition portion and is located above the second connecting portion to shield the second connecting portion;

[0064] The driving mechanism is provided with a knock-out hole, and the knock-out hole is arranged corresponding to the second connecting portion.

[0065] When the driving mechanism is arranged on the air outlet frame, a partition can be set between the driving mechanism corresponding to the air outlet and the maintenance port. The partition can be used to cover the driving mechanism so that the driving mechanism will not be exposed at the air outlet. On this basis, the driving mechanism can be used to cover the fasteners so that the fasteners are hidden under the driving mechanism and will not be exposed to affect the appearance. At the same time, a knock-out hole is set at the position of the driving mechanism corresponding to the fastener. When the electrical box needs to be repaired, the knock-out hole can be destroyed to facilitate disassembly of the fasteners.

[0066] In some embodiments of the present application, the maintenance panel extends upward along the height direction of the casing to the bottom end of the air outlet to cover the partition and the bottom of the door body.

[0067] The upper and lower parts of the partition define the air outlet and the maintenance port. The maintenance panel is used to cover the maintenance port, and the door body is used to cover the air outlet. Since the door body slides toward the inside of the casing, in order to improve the appearance of the casing, the maintenance panel can extend upward to cover the bottom of the partition and the door body, so that the maintenance panel and the door body appear visually integrated, thereby improving the appearance of the casing.

[0086] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0087] An embodiment of the present application discloses a vertical 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.

[0088] In some embodiments, see Figure 1 and Figure 2 The indoor unit 100 includes a housing 10 having an interior space 101. The housing 10 is provided with an air outlet 10a and an air inlet 10b communicating with the interior space 101. The housing 10 can be placed on the ground. The indoor unit 100 outputs hot air or cold air to the outside through the air outlet 10a.

[0089] In some embodiments, the indoor unit 100 includes an air outlet frame 20 , which is located in the internal space 101 and connected to the casing 10 to form a sliding space 20 a between the air outlet frame 20 and the casing 10 that is connected to the internal space 101 .

[0090] In some embodiments, the indoor unit 100 includes a sliding door structure 30 , which is slidably disposed at the air outlet 10 a .

[0091] In some embodiments, see Figure 2 and Figure 3 The sliding door structure 30 includes a driving mechanism 31, which is provided on the air outlet frame 20. Since the air outlet 10a has a longer extension length in the vertical air conditioner, the size of the door body 32 is also larger, in order to make the door body 32 run smoothly, so as to better drive the door body 32.

[0092] In some embodiments, the number of driving mechanisms 31 can be at least two, and the two driving mechanisms 31 can be respectively arranged at both ends of the air outlet 10a in the height direction, and respectively connected to the top and bottom ends of the door body 32, thereby driving the door body 32 to move more smoothly.

[0093] In some embodiments, the sliding door structure 30 further includes a door body 32 , which is connected to the driving mechanism 31 . The door body 32 slides in the sliding space 20 a under the drive of the driving mechanism 31 to cover or open the air outlet 10 a .

[0094] Optionally, the drive mechanism 31 may include a motor, a gear and a rack. The motor may be 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 32 to drive the sliding door to move synchronously, thereby realizing automatic opening or closing of the door body 32 without manual push, thereby improving the degree of automation.

[0095] In some embodiments, the indoor unit 100 of the vertical air conditioner is substantially cylindrical in shape, wherein the door body 32 may be arc-shaped, and the door body 32 may perform circular motion under the drive of the driving mechanism 31 .

[0096] In some embodiments, the indoor unit 100 includes a heat exchanger 40, which is disposed in the internal space 101 and located at the air inlet 10b. The heat exchanger 40 is used to exchange heat with the external air, absorb or release heat, and achieve cooling or heating effects.

[0097] In some embodiments, the indoor unit 100 includes a rotor 50 disposed within the interior space 101 along the height direction X of the housing 10, i.e., the rotation axis of the rotor 50 is perpendicular to the horizontal plane. The rotor 50 can be driven by a motor. When the vertical air conditioner is in operation, the motor drives the rotor 50 to rotate. External air first passes through the heat exchanger 40, undergoes heat exchange therewith, enters the rotor 50, and is blown out of the air outlet 10a under the action of the rotor 50.

[0098] In some embodiments, the indoor unit 100 further includes an air guide plate 60, which is located at the air outlet 10a. The air guide plate 60 can be rotated along the height direction of the air outlet 10a and connected to the air outlet frame 20. The air guide plate 60 can guide the wind direction of the air outlet 10a, so that the vertical air conditioner has a larger blowing range.

[0099] Optionally, there are multiple air guide plates 60, for example, two, three, four, etc., and the multiple air guide plates 60 can be arranged at intervals along the width direction Y of the air outlet 10a.

[0100] In some embodiments, the housing 10 includes a base 13 , which is disposed on the ground and can serve as a base for the vertical air conditioner, so that the vertical air conditioner can be placed more stably.

[0101] In some embodiments, the housing 10 includes a first panel 11 , which can be mounted on a base 13 .

[0102] In some embodiments, the housing 10 includes a second panel 12, with an air outlet 10a formed between the second panel 12 and the first panel 11. A sliding space 20a is formed between the first panel 11 and the air outlet frame 20. Specifically, the first panel 11 and the second panel 12 are spaced apart in the left-right direction to form the air outlet 10a therebetween. To open the air outlet 10a, the door 32 slides toward the first panel 11 and is concealed within the first panel 11.

[0103] In some embodiments, the casing 10 includes a rear shell 14, on which an air inlet 10b is provided. The two sides of the rear shell 14 can be connected to the air outlet frame 20, and the two sides of the air outlet frame 20 can be connected to the first panel 11 and the second panel 12, thereby forming an internal space 101 between the rear shell 14, the first panel 11 and the second panel 12.

[0104] In one example, the first panel 11 may be a panel located on the right side of the air outlet 10a. When a sliding space 20a is formed between the first panel 11 and the air outlet frame 20, the door body 32 may slide to the right to open the air outlet 10a.

[0105] In another example, the first panel 11 may be a panel located on the left side of the air outlet 10a. When a sliding space 20a is formed between the first panel 11 and the air outlet frame 20, the door body 32 may slide to the left to open the air outlet 10a.

[0106] In some embodiments, see Figures 4 to 7 The casing 10 is provided with an air cavity structure 102 protruding toward the internal space 101. The air cavity structure 102 is located on the sliding path of the door body 32. The air cavity structure 102 extends along the height direction X of the casing 10, and a cavity 102a is formed inside the air cavity structure 102.

[0107] In some embodiments, as Figure 5 The air cavity structure 102 includes a side wall portion 102 b , which is enclosed and connected to the housing 10 to form a cavity 102 a therebetween. The air cavity structure 102 is configured to enhance the strength of the housing 10 .

[0108] In some embodiments, the air cavity structure 102 can be integrally formed with the housing 10 through a gas-assisted injection molding process. During the molding process of the housing 10, the plastic melt of the housing 10 is first injected into the mold cavity, and then high-pressure gas is injected into the plastic melt. The high-pressure gas is used to generate a hollow cross-section inside the plastic part and the gas is used to push the plastic melt to fill various parts in the mold cavity, thereby forming a protruding air cavity structure 102 with a cavity 102a on the surface of the molded housing 10.

[0109] It should be noted that the high-pressure gas may refer to a gas having a higher pressure relative to atmospheric pressure, for example, a gas having a pressure greater than or equal to 1.6 MPa. In addition, the high-pressure gas may be an inert gas, such as nitrogen.

[0110] Compared to traditional injection molding, the high-pressure gas flow generated within the plastic melt effectively transmits pressure, reduces internal stress, and reduces warping of the molded housing 10. Furthermore, the pressure exerted by the high-pressure gas flow causes the housing 10 to shrink from the inside out, preventing any dents from forming on the cured housing 10, thereby improving the structural strength of the housing 10. Furthermore, the housing 10 formed using the gas-assisted injection molding process can save material, thereby helping to reduce production costs.

[0111] The vertical air conditioner provided in the present application has an air cavity structure 102 provided on the casing 10, which protrudes toward the internal space 101. The air cavity structure 102 is located on the sliding path of the door body 32 to enhance the strength of the casing 10 corresponding to the sliding space 20a. Compared to the method of providing additional sheet metal parts to enhance the strength of the casing 10 in the related art, the present application utilizes an air cavity structure 102 integrally formed with the casing 10 and having a cavity 102a formed therein. This can reduce, eliminate, or minimize surface defects such as warping, deformation, and collapse of the casing 10 caused by internal residual stress during the molding process, thereby enhancing the structural strength of the casing 10 itself and preventing deformation of the casing 10 from interfering with the movement of the door body 32. In addition, the air cavity structure 102 is integrally formed with the casing 10, which simplifies the number of components of the casing 10, eliminates the need for additional assembly, improves the assembly efficiency of the casing 10, and saves materials, thereby reducing production costs.

[0112] It can be understood that the air cavity structure 102 formed on the housing 10 by the gas-assisted injection molding process is equivalent to forming a hollow reinforcing rib, which can improve the strength of the housing 10 without increasing the weight of the housing 10 or slightly increasing the weight of the housing 10.

[0113] In some embodiments, the air cavity structure 102 extends from the top of the air outlet 10a to the bottom of the air outlet 10a, that is, the entire air cavity structure 102 is arranged in the length direction of the air outlet 10a, and its extension length is roughly consistent with the length of the air outlet 10a, which can greatly enhance the strength of the casing 10.

[0114] It can be understood that the air cavity structure 102 extends from the top of the air outlet 10a to the bottom of the air outlet 10a, and may include: the extension length of the air cavity structure 102 may be greater than the length of the air outlet 10a, so that the air cavity structure 102 can completely cover the top and bottom of the air outlet 10a, or, the extension length of the air cavity structure 102 may be slightly less than the length of the air outlet 10a, and the air cavity structure 102 may not completely cover the top or bottom of the air outlet 10a.

[0115] In some embodiments, a plurality of gas nozzles 102c protruding toward the internal space 101 are formed on the air cavity structure 102. The gas nozzles 102c are configured to inject gas into the interior of the air cavity structure 102 to form a cavity 102a. The plurality of gas nozzles 102c are arranged at intervals along the extension direction of the air cavity structure 102.

[0116] The air cavity structure 102 can be formed by injecting gas through the air nozzle 102c, and the air nozzle 102c protrudes from the outer surface of the air cavity structure 102. In this way, the wall thickness of the air cavity structure 102 can be thicker, thereby more effectively improving the strength of the housing 10.

[0117] In some embodiments, the air cavity structure 102 is a cylindrical convex strip, the diameter of the air cavity structure 102 is D1, the wall thickness of the housing 10 is D2, and the ratio of D1 / D2 satisfies: D1 / D2≥1.6.

[0118] When this condition is met, while the wall thickness of the casing 10 remains unchanged, the diameter of the air cavity structure 102 can be made relatively large, making it easier for the high-pressure gas in the cavity 102a to flow, thereby better promoting the filling of the plastic melt in the casing 10 and improving the molding quality of the casing 10.

[0119] In some embodiments, the diameter of the air cavity structure 102 is D1 , the wall thickness of the housing 10 is D2 , and the ratio of D1 / D2 satisfies: D1 / D2 ≤ 4.

[0120] Meeting this condition can control the diameter of the air cavity structure 102 and prevent the cavity 102a from being too large, thereby minimizing problems such as dents, warping, and shrinkage of the housing 10, thereby ensuring a more ideal molding quality and structural strength of the housing 10.

[0121] In some embodiments, the diameter of the air cavity structure 102 is D1, the wall thickness of the housing 10 is D2, and the ratio of D1 / D2 satisfies: 1.6≤D1 / D2≤4. For example, D1 / D2 can be 2, 2.5, 3, or 3.5.

[0122] By satisfying this condition, while maintaining the same wall thickness of the housing 10, the diameter of the air cavity structure 102 can be made relatively large, allowing the high-pressure gas in the cavity 102a to flow more easily, thereby further facilitating the filling of the plastic melt into the housing 10 and improving the molding quality of the housing 10. At the same time, the diameter of the air cavity structure 102 can be controlled, and the cavity 102a will not be too large, thereby minimizing the risk of dents, warping, and shrinkage in the housing 10, thereby ensuring ideal molding quality and structural strength of the housing 10.

[0123] In some embodiments, the air cavity structure 102 may also be semi-cylindrical, that is, the cross-sectional shape of the air cavity structure 102 may be circular or semi-circular, which can make the high-pressure gas flow more smoothly and reduce flow resistance, thereby improving the molding effect and molding quality of the casing 10.

[0124] In some embodiments, the diameter D1 of the air cavity structure 102 satisfies: D1 ≥ 5 mm.

[0125] Satisfying this relationship ensures that the cavity 102 a of the air cavity structure 102 is not too small, thereby providing a good passage for the gas, thereby facilitating the flow of the plastic melt of the housing 10 and improving the molding quality of the housing 10 .

[0126] In some embodiments, the diameter D1 of the air cavity structure 102 satisfies: D1≤10 mm.

[0127] Satisfying this relationship ensures that the diameter of the air cavity structure 102 is not too large, and further ensures that the air cavity structure 102 is not too protruding to affect the movement of the door body 32 .

[0128] In some embodiments, the diameter D1 of the air cavity structure 102 satisfies: 5 mm ≤ D1 ≤ 10 mm. For example, D1 may be 6 mm, 7 mm, 8 mm, or 9 mm.

[0129] By satisfying this relationship, the cavity 102a of the air cavity structure 102 will not be too small, thereby providing a good channel for the gas, which is beneficial to the flow of the plastic melt in the casing 10 and improves the molding quality of the casing 10. At the same time, the diameter of the air cavity structure 102 will not be too large, and the air cavity structure 102 will not protrude too much to affect the movement of the door body 32.

[0130] In some embodiments, the wall thickness D2 of the housing 10 satisfies: D2 ≥ 2.5 mm.

[0131] Satisfying this relationship ensures that the wall thickness of the casing 10 is not too small, which can avoid uneven flow of the plastic melt of the casing 10 in the mold, thereby maintaining the uniformity and consistency of the finished casing 10 and ensuring that the strength of the molded casing 10 meets the requirements.

[0132] In some embodiments, the wall thickness D2 of the housing 10 satisfies: D2≤3 mm.

[0133] Satisfying this relationship can make the plastic melt of the housing 10 flow smoothly, reduce the cooling time, and thus reduce defects such as shrinkage and bubbles on the surface of the housing 10, thereby improving the molding quality of the housing 10.

[0134] In some embodiments, the wall thickness D2 of the housing 10 satisfies: 2.5 mm ≤ D2 ≤ 3 mm. For example, D2 may be 2.6 mm, 2.7 mm, or 2.8 mm.

[0135] Meeting this relationship prevents the wall thickness of the housing 10 from being too small, preventing uneven flow of the plastic melt in the mold, thereby maintaining uniformity and consistency in the finished product, and ensuring that the strength of the molded housing 10 meets requirements. Furthermore, this ensures smooth flow of the plastic melt, reducing cooling time and thus minimizing surface defects such as shrinkage and bubbles on the housing 10 surface. This results in better molding quality and more ideal structural strength for the housing 10.

[0136] In some embodiments, the air cavity structure 102 includes a first air cavity 1021 , the first panel 11 is provided with the first air cavity 1021 , and the second panel 12 is connected to the air outlet frame 20 .

[0137] For example, since the first panel 11 needs to form a sliding space 20a with the air outlet frame 20, there is no connection between the side of the first panel 11 close to the air outlet 10a and the air outlet frame 20. In order to maintain the stable connection of the first panel 11, the side of the first panel 11 away from the air outlet 10a can be connected to the air outlet frame 20, and both sides of the second panel 12 can be connected to the air outlet frame 20.

[0138] By forming a sliding space 20a for the door body 32 to slide between the first panel 11 and the air outlet frame 20, that is, the door body 32 slides toward one side of the housing 10, compared to the method of sliding the door on both sides to open, there is no need to split the door body 32 into two parts, which can simplify the structure of the door body 32, and is more conducive to the assembly of the entire sliding door structure 30. When the door body 32 is closed, no gap is formed on the exterior surface of the vertical air conditioner due to the closure of the two parts of the door body 32, thereby improving the aesthetics of the vertical air conditioner. At the same time, forming the sliding space 20a on one side of the housing 10 not only allows the door body 32 to slide to open or cover the air outlet 10a, but also does not excessively occupy the internal space 101 of the housing 10, thereby facilitating the arrangement of internal components.

[0139] In some embodiments, the first panel 11 has a first edge 11 a close to the air outlet 10 a . The first edge 11 a extends along the height direction X of the housing 10 . The first air cavity 1021 is disposed at the first edge 11 a .

[0140] With the sliding space 20a formed between the first panel 11 and the air outlet frame 20, most of the first panel 11 is suspended in the air, making it very easy for the first panel 11 to sag inward and deform. Furthermore, the edges of the first panel 11, being relatively weak points, are more susceptible to damage or deformation. Therefore, by providing the first air cavity 1021 on the first edge 11a of the first panel 11 near the air outlet 10a, the structural strength and stability of the first panel 11 can be more effectively improved, making it less susceptible to deformation, thereby avoiding motion interference with the door body 32. Furthermore, the gap between the first panel 11 and the door body 32 when the air outlet 10a is blocked can be effectively maintained in the height direction, forming a uniform gap from top to bottom.

[0141] In some embodiments, continue to refer to Figures 4 to 6 The first edge 11a is provided with a first rib 11b protruding toward the internal space 101. The first rib 11b extends from the top of the air outlet 10a to the bottom of the air outlet 10a along the height direction X of the casing 10. The first rib 11b is configured to block the gap between the first panel 11 and the door body 32 when the door body 32 blocks the air outlet 10a, so that the user cannot see the black gap between the first panel 11 and the door body 32, thereby improving the appearance.

[0142] In some embodiments, the first air cavity 1021 is located at the junction of the first rib 11b and the first edge 11a. Since the intersection of the first rib 11b and the first edge 11a generally has a thicker wall, utilizing the thick wall at this intersection to form the first air cavity 1021 can more effectively ensure the molding quality of the first panel 11 having different wall thicknesses.

[0143] By providing a first retaining edge 11b protruding toward the internal space 101 on the first edge 11a, when the door body 32 blocks the air outlet 10a, the gap between the first panel 11 of the casing 10 and the door body 32 can be reduced, and no large black seam can be seen between the first panel 11 and the door body 32 in appearance, thereby improving the appearance of the vertical air conditioner.

[0144] In some embodiments, the second panel 12 has a second edge 12a proximate to the air outlet 10a. The second edge 12a extends along the height direction X of the housing 10. The second edge 12a is provided with a second rib 12b that protrudes toward the interior space 101. The second rib 12b is configured to block the gap between the second panel 12 and the door 32 when the door 32 blocks the air outlet 10a. This structure is consistent with the design of the first panel 11, and no large black gap is visible between the second panel 12 and the door 32, further improving the aesthetic appearance of the floor-standing air conditioner.

[0145] In some embodiments, the air cavity structure 102 further includes a second air cavity 1022, which is located at the junction of the second rib 12b and the second edge 12a. By forming the second air cavity 1022 using the thick wall at this junction, the molding quality of the second panel 12 with different wall thicknesses can be more effectively guaranteed.

[0146] By providing a second rib 12b protruding toward the interior space 101 on the second edge 12a of the second panel 12, the gap between the second panel 12 and the door 32 is reduced when the door 32 blocks the air outlet 10a. This eliminates the appearance of a large black gap between the second panel 12 and the door 32, thereby further improving the aesthetics of the floor-standing air conditioner. Furthermore, by providing a second air cavity 1022 at the intersection of the second rib 12b and the second edge 12a, the structural strength of the second panel 12 is increased, thereby preventing deformation or collapse of the second panel 12, which could affect the reliability of its installation.

[0147] It should be noted that the first panel 11 and the second panel 12 of the casing 10 are both connected to the air outlet frame 20. Specifically, the other edge of the first panel 11 opposite to the first edge 11a can be connected to one side of the air outlet frame 20, and the other edge of the second panel 12 opposite to the second edge 12a can also be connected to the other side of the air outlet frame 20.

[0148] Since the door body 32 can slide toward the first panel 11 and be hidden on the inner side of the first panel 11, the second edge 12a of the second panel 12 can be fully utilized and the second edge 12a of the second panel 12 can also be connected to the air outlet frame 20 to improve the connection stability of the second panel 12.

[0149] In some embodiments, see Figures 5 and 6 A first clamping portion 1022a is provided on the second air cavity 1022, and a second clamping portion 20b is provided on the air outlet frame 20. The first clamping portion 1022a and the second clamping portion 20b are matched and connected to realize the connection between the second edge 12a of the second panel 12 and the air outlet frame 20.

[0150] On the basis that the door body 32 can slide toward one side of the first panel 11 to achieve covering or opening the air outlet 10a, the second panel 12 does not need to reserve a sliding space 20a. Based on this, a first clamping portion 1022a is provided on the second edge 12a of the second panel 12, which cooperates with the second clamping portion 20b provided on the air outlet frame 20, and the first clamping portion 1022a and the second air cavity 1022 are combined. This can greatly enhance the strength of the panel itself while enhancing the stability of the connection of the second panel 12. The provision of the second air cavity 1022 increases the wall thickness at the second edge 12a. On this basis, the first clamping portion 1022a is provided to provide it with better bearing capacity, thereby reducing the possibility of the first clamping portion 1022a breaking due to the thin wall thickness.

[0151] In addition, when the second edge 12a is connected to the air outlet frame 20 through the cooperative connection of the first clamping portion 1022a and the second clamping portion 20b, a second retaining edge 12b is also protruded from the second edge 12a, which can absorb and disperse the external force acting on the second edge 12a to a certain extent, thereby improving the bearing capacity of the second panel 12.

[0152] Exemplarily, the first clamping portion 1022a can be a hook or a slot, and the second clamping portion 20b can be the other of the hook and the slot. The connection method of the hook and the slot is simple in structure and easy to assemble.

[0153] In the related art, the casing 10 is usually an integrated type. When the indoor unit 100 of the vertical air conditioner needs to be repaired, the casing 10 usually needs to be disassembled as a whole, which makes the repair process inconvenient.

[0154] Therefore, the researchers of this application considered providing a separate maintenance port 10c on the housing 10 and providing a detachable maintenance panel 80 to cover the maintenance port 10c. During maintenance, only the maintenance panel 80 needs to be removed. This will be described in detail below with reference to some embodiments.

[0155] In some embodiments, see Figure 3 The internal space 101 includes a first space 101 a and a second space 101 b along the height direction X of the housing 10 , and the second space 101 b is located below the first space 101 a .

[0156] In some embodiments, the heat exchanger 40 , the wind wheel 50 , and the air outlet frame 20 are all located in the first space 101 a , and the air outlet 10 a is connected to the first space 101 a .

[0157] In some embodiments, a maintenance port 10c is provided on the casing 10, and the maintenance port 10c and the air outlet 10a are spaced apart along the height direction X of the casing 10. A partition 103 is constructed between the maintenance port 10c and the air outlet 10a. The maintenance port 10c is located below the air outlet 10a and is connected to the second space 101b.

[0158] In some embodiments, the partition 103 can be a strip structure, a plate structure, etc. connected between the first panel 11 and the second panel 12, and the partition 103 can be integrally formed with the casing 10, so that the air outlet 10a and the maintenance port 10c are set at intervals. This is conducive to simplifying the structural design of the casing 10, eliminating the need for additional connections, and improving the assembly efficiency of the casing 10.

[0159] In some embodiments, the indoor unit 100 further includes an electrical box 70, which is located in the second space 101b and near the maintenance port 10c. The electrical box 70 is mainly used to control the working mode of the air conditioner, adjust the indoor temperature and humidity, and ensure the safe operation of the air conditioning system.

[0160] For example, the electrical box 70 may include a control circuit board, a power supply circuit board, and external components such as a pipe temperature sensor, an indoor temperature sensor, a signal receiving circuit, and a transformer.

[0161] In some embodiments, see Figure 8 The indoor unit 100 further includes a maintenance panel 80 , which is detachably connected to the housing 10 to cover the maintenance port 10 c to maintain the appearance of the indoor unit 100 .

[0162] By forming a separate maintenance port 10c in the housing 10 and placing the electrical box 70 near the maintenance port 10c, when the electrical box 70 needs to be repaired, the electrical box 70 can be repaired or replaced by simply removing the maintenance panel 80, which corresponds to the electrical box 70, without having to disassemble the entire housing 10. This simplifies the maintenance process and improves the convenience of maintenance. In addition, it can be understood that the air outlet 10a is located on the main exterior surface of the housing 10 that can be observed by the user, and the maintenance port 10c is set below the air outlet 10a, and the maintenance panel 80 is used to cover the maintenance port 10c. The maintenance panel 80 is combined with the housing 10 of the vertical air conditioner, so that when maintenance is required, it can be carried out directly without having to move the entire vertical air conditioner significantly, which can further improve the convenience of maintenance of the vertical air conditioner.

[0163] In some embodiments, see Figure 9 The maintenance panel 80 is provided with a first connection portion 81, and the housing 10 is provided with a second connection portion 104. The first connection portion 81 and the second connection portion 104 are configured to allow fasteners to pass through.

[0164] Exemplarily, the first connection portion 81 and the second connection portion 104 may both be through holes 104a for fasteners to pass through, or the first connection portion 81 may be a connection column with a threaded hole, and the second connection portion 104 may be a through hole 104a.

[0165] For example, the fastener may be a connecting member such as a screw or a bolt.

[0166] In some embodiments, the maintenance panel 80 is provided with a third clamping portion 82 , and the housing 10 is provided with a fourth clamping portion 105 , and the third clamping portion 82 and the fourth clamping portion 105 are cooperatively connected.

[0167] Illustratively, the third engaging portion 82 may be a hook or a slot, and the fourth engaging portion 105 may be the other of the hook or the slot. The connection method of the hook and the slot is simple in structure and easy to assemble.

[0168] By using the fasteners and the snap-fit ​​connection, the maintenance panel 80 can be more firmly fixed to the housing 10 , thereby improving the stability of the connection of the maintenance panel 80 .

[0169] In some embodiments, the partition portion 103 has a first inner wall surface 103 a , the second connection portion 104 is protruded from the first inner wall surface 103 a , and a through hole 104 a is defined in the second connection portion 104 and passes through the housing 10 in the height direction X.

[0170] In some embodiments, the maintenance panel 80 has a second inner wall surface 80 a , the first connection portion 81 is protruded from the second inner wall surface 80 a , and the fastener is configured to pass through the second connection portion 104 along the height direction X of the housing 10 and connect with the first connection portion 81 .

[0171] In some embodiments, the maintenance panel 80 is provided with third clamping portions 82 on both sides in the width direction of the air outlet 10 a.

[0172] Exemplarily, the number of the third clamping parts 82 can be multiple, for example, the third clamping part 82 on one side of the maintenance panel 80 can be multiple hooks, and the fourth clamping part 105 cooperating therewith can be a slot, and the third clamping part 82 on the other side of the maintenance panel 80 can be multiple slots, and the fourth clamping part 105 cooperating therewith can be a hook. In this way, the maintenance panel 80 can be installed on one side first, and then the other side can be assembled into place, so that the maintenance panel 80 will not be excessively deformed during the installation process, thereby avoiding the possibility of the clamping part breaking.

[0173] By arranging the snap-fit ​​portions on both sides of the maintenance panel 80 and then arranging the first connection portion 81 connected by the fasteners at the end of the maintenance panel 80, the connection points of the maintenance panel 80 can be more evenly distributed, thereby making the connection of the maintenance panel 80 more stable.

[0174] In addition, the first connecting portion 81 that requires fastener connection is set at one end of the maintenance panel 80 close to the air outlet 10a, and the second connecting portion 104 is set on the partition 103 between the air outlet 10a and the maintenance port 10c. On the one hand, the connecting portion can be hidden inside the casing 10 so that the fastener will not be exposed on the exterior surface, thereby improving the appearance of the casing 10; on the other hand, the fastener can be connected to the connecting portion in a vertical direction. When the fastener is removed, maintenance can be performed from the air outlet 10a. This setting position is more reasonable and easier to maintain and disassemble.

[0175] In some embodiments, see Figure 10 The driving mechanism 31 is disposed at the partition portion 103 and is located above the second connecting portion 104 to shield the second connecting portion 104 .

[0176] When the driving mechanism 31 is set on the air outlet frame 20, the driving mechanism 31 can be set at the partition 103 between the air outlet 10a and the maintenance port 10c. The partition 103 can be used to cover the driving mechanism 31 so that the driving mechanism 31 will not be exposed at the air outlet 10a. On this basis, the driving mechanism 31 can be used to cover the fasteners so that the fasteners are hidden under the driving mechanism 31 and will not be exposed to affect the appearance.

[0177] In some embodiments, a knock-out hole 31 a is provided on the driving mechanism 31 . The knock-out hole 31 a is provided corresponding to the second connecting portion 104 . The knock-out hole 31 a can be removed by gently tapping the knock-out hole 31 a with a screwdriver or other tools.

[0178] A knockout hole 31a is provided at the position of the fastener corresponding to the driving mechanism 31. When the electrical box 70 needs to be repaired, the knockout hole 31a can be destroyed, and the through hole 104a is exposed or enlarged to expose the fastener so that the fastener can be removed, and the maintenance panel 80 can be further removed to repair the electrical box 70.

[0179] In some embodiments, the maintenance panel 80 extends upward along the height direction X of the housing 10 to the bottom end of the air outlet 10 a to shield the partition 103 and the bottom of the door 32 .

[0180] The upper and lower parts of the partition define the air outlet 10a and the maintenance port 10c. The maintenance panel 80 is used to cover the maintenance port 10c, and the door body 32 is used to cover the air outlet 10a. Since the door body 32 slides toward the inside of the casing 10, in order to improve the appearance of the casing 10, the maintenance panel 80 can extend upward to cover the bottom of the partition 103 and the door body 32, so that the maintenance panel 80 and the door body 32 appear visually integrated, thereby improving the appearance of the casing 10.

[0181] The above is a detailed introduction to the vertical 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 vertical air conditioner of the present application and its core concept. At the same time, for those skilled in the art, according to the concept of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present application.
