Description

[0001] This application is a divisional application with application number 202010400953.2, patent name "rear shell assembly of floor-standing air conditioner, indoor unit of floor-standing air conditioner and air conditioner", and application date 2020-05-12. Technical Field

[0002] The invention relates to the technical field of air conditioning, and in particular to a rear shell component of a floor-standing air conditioner, a floor-standing air conditioner indoor unit and an air conditioner. Background Art

[0003] In order to ensure the cleanliness of the heat exchanger, existing floor-standing air conditioners are equipped with a filter on the inner side of the air inlet grille. Since the air inlet grille is relatively long and has a large deformation after injection molding, the gap between the filter handle and the air inlet grille will be uneven after the filter is installed, resulting in poor overall consistency. In order to control the gap between the filter handle and the air inlet grille, a reinforcing sheet metal is usually fixed to the air inlet grille to reduce the deformation of the air inlet grille by correction, thereby reducing the gap between the air inlet grille and the filter handle. This method requires an additional reinforcing sheet metal part, which increases the cost, and because the reinforcing sheet metal needs to be fixed to the air inlet grille first, the installation efficiency is reduced.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B.

[0052] The invention provides a rear shell assembly of a floor-standing air conditioner.

[0053] In the embodiment of the present invention, Figures 1 to 19As shown, the rear shell assembly 100 of the floor-standing air conditioner includes a housing 110, an air inlet grille 120 and a filter assembly 130. The housing 110 is provided with an air inlet 111; the air inlet grille 120 is installed at the air inlet 111 of the housing 110, and a socket 112 is formed between the end of the air inlet grille 120 and the housing 110. The filter assembly 130 includes a filter handle 132 and a filter 131 connected to the filter handle 132. The filter assembly 130 is plugged into the housing 110 through the socket 112 so that the filter 131 is arranged corresponding to the air inlet grille 120. The filter handle 132 is installed in the socket 112, and one side of the filter handle 132 is fixed to the periphery of the air inlet grille 120, and the other side is fixed to the housing 110.

[0054] In this embodiment, the shell 110 extends roughly in the up-down direction, and the cross-sectional shape of the shell 110 can be circular, elliptical, arc-shaped, rectangular, etc. The shell 110 can be the outer shell of the entire floor-standing air-conditioning indoor unit, or it can be only the rear shell of the floor-standing air-conditioning indoor unit. In order to increase the air intake, the air inlet 111 can also be extended up and down, so that the air inlet 111 is a long strip as a whole, and can be a long ellipse, a rectangle, etc. In one embodiment, the air inlet grille 120 is integrally formed with the shell 110. In another embodiment, the air inlet grille 120 is detachably connected to the shell 110. The air inlet grille 120 and the shell 110 can be detachably connected by means of buckles, screws, magnetic suction, etc. In this way, the air inlet grille 120 is easy to disassemble and clean.

[0055] The filter assembly 130 specifically includes a filter 131 and a filter handle 132. The filter 131 is arranged corresponding to the air inlet grille 120 and is adapted to the air inlet surface of the air inlet grille 120 to filter dust, debris, etc. in the air entering from the air inlet 111. The filter handle 132 can be a plastic part or a sheet metal part. The filter handle 132 and the filter 131 can be integrally formed or separately formed, and connected by bonding, snap-fitting, pressing, etc. Since the filter 131 is usually a thin and soft structure, by providing the filter handle 132, it is convenient for the user to plug and unplug the filter 131 through the filter handle 132, thereby facilitating the installation and removal of the filter 131. The filter handle 132 is generally in the shape of a long strip, and a groove can be provided in the portion of the filter handle 132 exposed from the socket 112 for the user to grasp. It is understandable that, in order to maintain the consistency of appearance, the end surface of the filter handle 132 exposed at the socket 112 is flush with the side surface of the housing 110. By installing the filter assembly 130 into the housing 110 through the socket 112, the filter assembly 130 is independently detachable. Compared with integrating the filter 131 on the air inlet grille 120 and disassembling the air inlet grille 120 as a whole, the disassembly method is more convenient and quick, and it is convenient for the user to clean the filter 131 separately.

[0056] It is understandable that the socket 112 can be provided on the top wall, the left wall or the right wall of the housing 110. The socket 112 provides a limited installation space for one end of the filter assembly 130, so that the user can directly insert the filter assembly 130 into the slot from top to bottom, from left to right or from right to left without disassembling the housing 110. In one embodiment, one end of the filter 131 relative to the filter handle 132 is snapped to the air inlet grille 120 or the housing 110, or one end of the filter 131 relative to the filter handle 132 is plugged into the air inlet grille 120 or the housing 110. A socket 132a or a buckle can be provided on the air inlet grille 120 to achieve plugging or snapping with one end of the filter 131 relative to the filter handle 132. In this way, the opposite ends of the filter assembly 130 are connected to the air inlet grille 120 or the housing 110, thereby tightening the filter 131 to prevent the filter 131 from swinging under the action of the airflow.

[0057] It should be noted that the filter handle 132 is installed in the socket 112, one side of the filter handle 132 is fixed to the air inlet grille 120, and the other side is fixed to the housing 110. This means that when the filter assembly 130 is installed in place as a whole, the filter handle 132 cannot move relative to the air inlet grille 120 without the action of external force, and the filter handle 132 cannot move relative to the housing 110, and the three are tightly connected. Under the action of external force, the filter assembly 130 can be pulled out of the socket 112 as a whole by the action of external force, so as to realize the overall disassembly and replacement of the filter assembly 130.

[0058] For details, please refer to Figures 4 to 18The side of the filter handle 132 close to the air inlet grille 120 can be connected to the air inlet grille 120 by means of buckle, magnetism, suction cup, etc., and the side of the filter handle 132 away from the air inlet grille 120 can be connected to the housing 110 by means of buckle, magnetism, suction cup, etc., so that the air inlet grille 120 is tightened to the housing 110 through the filter handle 132. Due to the high structural strength of the housing 110, a tensioning force is formed between the filter handle 132 and the air inlet grille 120, and a tensioning force is formed between the filter handle 132 and the housing 110, thereby tightening the air inlet grille 120 to the housing 110, thereby avoiding overall deformation while making the gap between the air inlet grille 120 and the filter handle 132 smaller and more uniform. Since the air inlet grille 120 of the floor-standing air conditioner is relatively long, the air inlet grille 120 is deformed greatly after injection molding, so that the gap between the filter handle 132 and the air inlet grille 120 is uneven, which may cause air leakage, thereby affecting the air intake and filtering effects, and the shape is not beautiful. By making the two sides of the filter handle 132 tightly connected to the air inlet grille 120 and the housing 110 respectively, so that the air inlet grille 120 is tightened to the housing 110 through the filter handle 132, while the filter assembly 130 is installed, the filter handle 132 can be close to the housing 110, and the air inlet grille 120 can be close to the filter handle 132, so that the gap between the filter handle 132 and the housing 110, and the air inlet grille 120 and the filter assembly 130 is small and uniform, reducing the impact of the gap on the air intake and filtering effects, and improving the appearance. The filter handle 132 can correct and reduce the deformation of the air inlet grille 120, thereby reducing the gap between the air inlet grille 120 and the filter handle 132. There is no need to set up a reinforced sheet metal part to correct the air inlet grille 120, which reduces costs, reduces installation processes, and improves installation efficiency. When the air inlet grille 120 is a planar structure, the filter handle 132 corrects and reduces the deformation of the air inlet grille 120, and at the same time, it can make the filter 131 and the air inlet grille 120 fit more closely, thereby achieving better filtering and air intake effects and maintaining overall consistency in appearance.

[0059] The rear housing assembly 100 of the floor-standing air conditioner of the present invention is such that the filter assembly 130 is inserted into the housing 110 through the socket 112, and the filter handle 132 is installed in the socket 112, one side of the filter handle 132 is connected to the periphery of the air inlet grille 120, and the other side is connected to the housing 110. By utilizing the structural strength of the housing 110, while the filter assembly 130 is installed, the deformation of the air inlet grille 120 is corrected and reduced by the filter handle 132, and the gap between the air inlet grille 120 and the filter handle 132 is reduced, so that one side of the filter handle 132 is closely attached to the housing 110, and the other side is closely attached to the air inlet grille 120, so that the gap between the filter handle 132 and the housing 110, and between the filter handle 132 and the air inlet grille 120 is small and uniform. In addition, without reinforcing the sheet metal, the gap between the filter handle 132 and the air inlet grille 120 is guaranteed, which greatly reduces the cost and improves the installation efficiency.

[0060] Specifically, if Figures 4 to 18 As shown, the filter handle 132 is magnetically and / or snap-connected to the air inlet grille 120 , and the filter handle 132 is magnetically and / or snap-connected to the housing 110 .

[0061] In this embodiment, the filter handle 132 and the air inlet grille 120 can be connected only by a magnetic member, or only by a snap member, or by both a magnetic member and a snap member. The number of magnetic members and snap members can be one or more. When there are multiple magnetic members and snap members, multiple magnetic members and snap members are extended along the length direction of the filter handle 132 and the air inlet grille 120. The filter handle 132 and the housing 110 can be connected only by a magnetic member, or only by a snap member, or by both a magnetic member and a snap member. The number of magnetic members and snap members can be one or more. When there are multiple magnetic members and snap members, multiple magnetic members and snap members are extended along the length direction of the filter handle 132 and the housing 110. In one embodiment, a first magnetic member is provided on the filter handle 132, and a second magnetic member and a third magnetic member are provided on the air inlet grille 120 and the housing 110 respectively corresponding to the first magnetic member. The first magnetic member, the second magnetic member and the third magnetic member can be permanent magnets. The first magnetic member can also be a permanent magnet, and the second magnetic member and the third magnetic member can be electromagnets. In this way, after the filter handle 132 is inserted into the slot, the electromagnet is energized by remote control, buttons or induction devices, so that the filter handle 132 is magnetically connected to the housing 110 and the air inlet grille 120 respectively. When the filter assembly 130 needs to be disassembled, the filter assembly 130 can be easily removed by simply turning off the power to the electromagnet. The structure is simple, easy to implement, and the connection is stable.

[0062] In one embodiment, if Figure 1 , Figure 2 and Fig.14As shown, the air inlet grille 120 is extended in the up-down direction, and the socket 112 is opened on the side wall surface of the housing 110 and is extended in the up-down direction.

[0063] In this embodiment, the air inlet grille 120 is extended in the up-down direction, so that the air intake of the air inlet 111 is large enough to meet the user's blowing needs. The socket 112 is specifically provided on the left and right sides of the housing 110. In this way, the user can insert the filter 131 from left to right or from right to left, and the operation space is large, making it easy for the user to replace the filter 131.

[0064] For further information, please refer to Figures 8 to 10 , Fig.14 and Fig.15 , one of the filter handle 132 and the air inlet grille 120 is provided with a latch 121, and the other is provided with a socket 132a adapted to the latch 121. During installation, the filter 131 is first inserted into the slot through the socket 112, and when the filter handle 132 is pushed, the air inlet grille 120 and the filter handle 132 are adapted through the latch 121 and the socket 132a. By making the filter handle 132 and the air inlet grille 120 realize a snap connection through the latch 121 and the socket 132a, on the one hand, the air inlet grille 120 and the filter 131 can be tightened, and on the other hand, the filter handle 132 and the air inlet grille 120 can be easily separated from each other. In other embodiments, one of the filter handle 132 and the air inlet grille 120 can also be provided with a snap, and the other can be provided with a slot that matches the snap. To achieve a snap connection between the filter handle 132 and the air inlet grille 120.

[0065] On the basis of the above embodiments, further, the air inlet grille 120 is arranged in an arc shape or a U shape, and a pin 121 is protruding from the periphery of the air inlet grille 120 near the filter handle 132. The extension direction of the pin 121 is arranged away from the insertion direction of the filter handle 132, and a hole 132a is provided at the position of the filter handle 132 corresponding to the pin 121.

[0066] In this embodiment, the air inlet grille 120 can be arranged in an arc shape as a whole, or only partially in an arc shape, or in a U-shape, so that the air inlet grille 120 can achieve multi-directional air intake, thereby increasing the air intake volume of the floor-standing air conditioner indoor unit. By providing a latch 121 on the air inlet grille 120, and making the extension direction of the latch 121 away from the insertion direction of the filter handle 132, the latch 121 has a certain inclination, so that the latch 121 and the plug hole 132a are obliquely adapted and plugged. In this way, when the filter handle 132 is inserted into the slot, the pin 121 on the air inlet grille 120 abuts against the socket 132a on the filter handle 132, and has a component force that pushes the filter handle 132 away from the insertion direction of the filter handle 132, thereby pushing and tightening the filter 131. After the filter handle 132 is snap-connected with the shell 110, the air inlet grille 120 is further tightened to reduce the gap between the filter handle 132 and the air inlet grille 120.

[0067] In one embodiment, if Figures 4 to 7 , Figures 11 to 13 , Figures 16 to 18 As shown, a clamping piece 132b is provided on the side of the filter handle 132 away from the air inlet grille 120, and a matching piece 113 adapted to the clamping piece 132b is provided at the socket 112 of the housing 110. The matching piece 113 can be a clamping groove provided on the housing 110, or a buckle adapted to the clamping piece 132b. Since the housing 110 has good structural strength and small deformation, the filter handle 132 and the housing 110 can be connected more tightly by making the filter handle 132 and the housing 110 buckle-connected through the clamping piece 132b and the matching piece 113, so that the housing 110 tightens the filter handle 132 through the clamping piece 132b and the matching piece 113, and the filter handle 132 tightens the air inlet grille 120 through the latch 121, so that the housing 110 and the filter handle 132, and the filter handle 132 and the air inlet grille 120 fit more tightly.

[0068] On the basis of the above embodiment, further, the clamping member 132b is a hook, and the matching member 113 is an elastic buckle, the elastic buckle includes two clamping arms 113a that are opposite and spaced apart, and an installation space 113b is formed between the two clamping arms 113a, and the opening of the installation space 113b is arranged toward the hook, and the hook is clamped in the installation space 113b.

[0069] In this embodiment, the hook can be specifically dumbbell-shaped, that is, a structure with a large top and a small middle. The elastic buckle can be specifically hourglass-shaped, with a large opening at the top, narrowed in the middle, and a larger opening at the bottom. The two holding arms 113a of the elastic buckle are elastic, so that the size of the installation space 113b can be changed, which is convenient for the engagement and disengagement of the hook, and at the same time, the elastic buckle and the hook form an inverted structure, so that the rear shell can tighten the filter handle 132. Based on the embodiment in which the filter handle 132 and the air inlet grille 120 are matched through the plug hole 132a of the latch 121, when installing the filter assembly 130, the filter 131 is first inserted into the slot, and when the filter handle 132 is pushed, the latch 121 on the air inlet grille 120 is first inserted into the plug hole 132a of the filter handle 132, and then the push continues, and the hook of the filter handle 132 is inserted into the elastic buckle for engagement. In this way, the housing 110 tightens the filter handle 132 through the hook and the elastic buckle, and the filter handle 132 tightens the air inlet grille 120 through the latch 121, thereby making the housing 110 and the filter 131, and the filter 131 and the air inlet grille 120 fit more closely.

[0070] In one embodiment, please refer to Fig.10 and Fig.11 The filter handle 132 has a plug hole 132a on one side close to the air inlet grille 120, and a clamping piece 132b on the side away from the air inlet grille 120. The air inlet grille 120 has a latch 121 matched with the plug hole 132a, and the housing 110 has a matching piece 113 matched with the clamping piece 132b. There are multiple clamping pieces 132b, which are arranged at intervals along the length direction of the filter handle 132, and a plug hole 132a is correspondingly arranged between two adjacent clamping pieces 132b.

[0071] In this embodiment, the filter handle 132 is adapted to the air inlet grille 120 through the plug 121 and the plug hole 132a, and the filter handle 132 is connected to the housing 110 through the clip 132b.
