Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a sealed telescopic curtain assembly and a window air conditioner. Background Art

[0002] Due to the high cost of manual installation and low efficiency of manual service in North America, window air conditioners with the characteristics of low price, easy use, and no need for professional installation have a demand that cannot be underestimated in the North American air conditioning market. In addition to North America, window air conditioners (also known as window units) also have a certain market in some domestic regions such as Taiwan. For different regions, the sizes of windows are different, and the specifications of window air conditioners used may also be different. The corresponding sizes of telescopic curtain assemblies are matched for window units of different specifications, resulting in low universality of telescopic curtain assembly materials. How to improve the universality of the company's telescopic curtain assembly materials, while ensuring the sealing and thermal insulation performance of the telescopic curtain assembly to meet users' packaging requirements for different models of window air conditioners has become a problem that needs to be solved urgently. In order to overcome the aforementioned problems, the prior art with publication number CN 216788242 U proposes a structure in which the height and length of the frame can be telescopically adjusted. However, the vertically height-adjustable frame is formed into a relatively sliding frame assembly by a simple inside-outside nested assembly, wherein the outer side surface of the inner frame and the outer side surface of the outer frame are not in the same plane. When it is assembled with the corresponding window frame, in order to ensure the sealing effect of the outer side of the frame, it is necessary to seal the gap between the outer side surface of the inner frame and the window frame. The installation process of the telescopic curtain assembly is relatively cumbersome and increases the chance of after-sales service. Summary of the invention

[0003] Therefore, the present invention provides a sealed retractable curtain assembly and a window air conditioner, which can solve the technical problems in the prior art that after the vertical frame of the height-adjustable retractable curtain frame assembly is matched with the window frame and installed, there is a large gap between the two, the sealing effect is poor, or the gap needs to be sealed separately, resulting in a relatively cumbersome installation process and an increased chance of after-sales service.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0051] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0052] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0053] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0056] See also Figures 1 to 10According to an embodiment of the present invention, a sealed telescopic curtain assembly is provided, comprising: a frame assembly (not labeled in the figure) and a telescopic curtain (not labeled in the figure) assembled inside the frame assembly, wherein the frame assembly comprises a first frame 1 (with Figure 1 The orientation shown is for reference, which can be called the upper frame) and the second frame 2 (with Figure 1 The orientation shown is for reference, which can be called the lower frame), the first frame 1 has a side away from the telescopic curtain along its length direction (that is, Figure 1 The first slide groove 10 extends in the up and down direction of the orientation shown in the figure, and the second frame 2 is partially inserted in the first slide groove 10 so as to be able to slide along the extension direction of the first slide groove 10. When the first frame 1 and the second frame 2 are assembled, the side surface of the second frame 2 away from the telescopic curtain and the side surface of the first frame 1 away from the telescopic curtain are on the same plane. Figure 1 The orientation shown is for reference only, that is, the left side surfaces of the first frame 1 and the second frame 2 are on the same vertical plane.

[0057] In this technical solution, the height of the frame assembly can be adjusted by sliding, thereby meeting the specifications and models of different window air conditioners and window sizes, improving its versatility. More importantly, the first frame 1 and the second frame 2 of the height-adjustable frame assembly are both assembled with the external plane (such as a window frame) on the same plane, eliminating the formation of a gap between the frame assembly and the external plane when the two are assembled, reducing the sealing of the sealed telescopic curtain assembly, eliminating the need for subsequent sealing of the gap, and thus eliminating the occurrence of subsequent after-sales problems that may exist in the sealing of the gap.

[0058] In a preferred embodiment, see Figure 2 As shown, the first frame 1 includes a first vertical section 11, and the first vertical section 11 includes a first middle matching plate 111 extending in the vertical direction and side grooves 112 located on both sides of the first middle matching plate 111, wherein the side groove 112 has a first groove wall 1121 on a side away from the first middle matching plate 111, and the top surface of the first groove wall 1121 (the top surface here refers to the side of the first groove wall 1121 away from the telescopic curtain, that is, Figure 1 The distance between the left end of the position shown in the figure and the plate surface of the first intermediate matching plate 111 away from the telescopic curtain is d (in Figure 1 Taking the orientation shown, that is, the orientation of the frame assembly in the installed state as an example, the aforementioned spacing is a horizontal spacing), the second frame 2 includes a second vertical segment 21, the second vertical segment 21 includes a second middle matching plate 211 in contact with the first middle matching plate 111, and the thickness of the second middle matching plate 211 is d.

[0059] In the above-mentioned technical solution, the thickness of the second middle matching plate 211 is designed to be equal to the horizontal distance between the top surface of the first groove wall 1121 and the plate surface of the first middle matching plate 111 away from the telescopic curtain. After the first frame 1 and the second frame 2 are assembled, this size relationship ensures the coplanar design of the outer sides of the two, which is simple and convenient.

[0060] See Figure 5 As shown, in some embodiments, the first middle matching plate 111 has a receiving groove 113 on one side close to the telescopic curtain, and the receiving groove 113 extends along the length direction of the first vertical section 11, and the curtain body end corresponding to the telescopic curtain is received in the receiving groove 113, so as to Figure 1 Taking the position shown as an example, the left end of the telescopic curtain will be accommodated in the accommodating groove 113. It can be understood that since the telescopic curtain needs to change in height along with the height change of the frame assembly, the position corresponding to the aforementioned first vertical section 11 of the telescopic curtain cannot be fixedly connected. In this application, accommodating the curtain body end of the telescopic curtain in the accommodating groove 113 can improve the internal and external sealing at the matching position. At this time, the cross-section of the first vertical section 11 is objectively in the shape of a "bow".

[0061] See Figure 6 As shown, the second vertical section 21 also includes two side panels 212 corresponding to the side grooves 112. The two side panels 212 are respectively accommodated in the side grooves 112. Through the concave and convex corresponding accommodation relationship between each side panel 212 and the corresponding side grooves 112, the stability and reliability of the relative sliding between the first frame 1 and the second frame 2 can be guaranteed.

[0062] See also Figures 3 to 6 As shown, in some embodiments, at least one of the side plates 212 and the corresponding side groove 112 has a positioning structure, see Figure 3 As shown, a positioning structure is provided between the two side plates 212 and the corresponding side grooves 112. The relative height of the first frame 1 and the second frame 2 can be locked by the positioning structure to ensure the structural stability and reliability of the frame assembly.

[0063] In a specific embodiment, the first groove wall 1121 of the side groove 112 has a plurality of positioning teeth 1122 arranged at intervals along the length direction of the first vertical section 11 on one side wall surface close to the first middle matching plate 111, and the side of the side plate 212 facing the first groove wall 1121 is a positioning side surface, and a positioning spring piece 2121 is provided on the positioning side surface, and the positioning spring piece 2121 can switch between the positioning grooves 1123 formed between the positioning teeth 1122, and the aforementioned positioning structure is also composed of the aforementioned positioning teeth 1122, the positioning grooves 1123 and the positioning spring piece 2121. In this technical solution, the relative position of the first frame 1 and the second frame 2 is reliably locked by the snap-fit ​​relationship between the positioning spring piece 2121 and any one of the positioning grooves 1123.

[0064] See Figure 6 As shown, two relatively spaced limiting hooks 2122 are formed on the positioning side surface, and the two free ends of the positioning spring piece 2121 are respectively inserted into each of the limiting hooks 2122. When the positioning spring piece 2121 is in the positioning groove 1123, there is a deformation space between at least one of the two free ends of the positioning spring piece 2121 and the limiting hook 2122. When adjusting the height of the frame assembly, the first frame 1 is lifted or pressed down. Under the action of tension or pressure, the positioning teeth 1122 of the first frame 1 will press the positioning spring piece 2121, and at least one end of the compressed positioning spring piece 2121 will deform toward the deformation space, so that the positioning spring piece 2121 is switched from one positioning groove 1123 to another adjacent positioning groove 1123, and the height adjustment is smoother.

[0065] The aforementioned positioning spring piece 2121 can specifically be a triangular iron spring piece structure, and of course other structural types can also be used.

[0066] In some embodiments,

[0067] The first frame 1 also includes a top horizontal section 12, a first end of the top horizontal section 12 is connected to the first end of the first vertical section 11 and the two are perpendicular, the second frame 2 also includes a bottom horizontal section 22, a first end of the bottom horizontal section 22 is connected to the first end of the second vertical section 21 and the two are perpendicular, so that the frame assembly forms a [ shape, and the opening of the [ shape faces one side of the window air conditioner, the top end of the telescopic curtain is connected to the bottom surface of the top horizontal section 12, the bottom end of the telescopic curtain is connected to the top surface of the bottom horizontal section 22 and the telescopic direction of the telescopic curtain is parallel to the extension direction of the first vertical section 11, that is, the telescopic direction of the telescopic curtain is the vertical direction, and it can be telescoped following the height adjustment of the frame assembly, thereby improving the high versatility of the telescopic curtain.

[0068] See Fig.10 As shown, the telescopic curtain includes an outer telescopic curtain 31 and an inner telescopic curtain 32, the outer telescopic curtain 31 includes a first outer curtain body and a first inner curtain body that are spaced apart (the inner and outer sides of the outer curtain body and the inner curtain body are defined by the side located indoors as the inner side and the side located outdoors as the outer side), a storage space is formed between the first outer curtain body and the first inner curtain body, the inner telescopic curtain 32 is inserted into the storage space, and has a storage and ventilation state that is completely located within the storage space and a sealed and heat-insulating state that is at least partially located outside the storage space, and the inner telescopic curtain 32 can be pushed and pulled along the extension direction of the top horizontal section 12 to achieve switching of its state.

[0069] In this technical solution, an inner telescopic curtain 32 is inserted into the storage space of the outer telescopic curtain 31. Since the inner telescopic curtain 32 has a sealed heat-insulating state and a storage ventilation state, the user can push and pull the inner telescopic curtain 32 according to needs to meet different working conditions. For example, when the room needs to be ventilated, the inner telescopic curtain 32 is pushed into the storage space, and the airflow is connected inside and outside. When sealing and heat preservation are required, the inner telescopic curtain 32 is pulled outward and sealed to the window air conditioner on one side, thereby preventing the airflow from circulating inside and outside.

[0070] The first outer curtain body is provided with a second slide groove 311 that runs through the inside and outside of the first outer curtain body. The second slide groove 311 is extended along the push-pull direction of the inner telescopic curtain 32. A slider 321 is provided on the side of the inner telescopic curtain 32 close to the first outer curtain body. The slider 321 is slidably connected to the second slide groove 311 and is located in the area of ​​the inner telescopic curtain 32 close to the window air conditioner. In this technical solution, through the sliding cooperation relationship between the slider 321 and the second slide groove 311, the user can push and pull the inner telescopic curtain 32 by applying force to the slider 321 to switch the state of the inner telescopic curtain 32. At the same time, the slider 321 is in the second slide groove 311 and does not move relative to each other in the vertical direction. In this way, when the height of the frame assembly is adjusted, the slider 321 can maintain the consistency of the height change of the inner telescopic curtain 32 and the outer telescopic curtain 31.

[0071] In some embodiments, there is a gap between the slider 321 and the side of the inner telescopic curtain 32, the gap is s, the thickness of the first inner curtain body is h, 0.95h≤s≤h, and the slider 321 has a sliding state and a locking state. When the slider 321 is in the sliding state, the slider 321 is completely in the notch of the second slide groove 311, and when the slider 321 is in the locking state, the slider 321 is at least partially outside the notch of the second slide groove 311 and on the side of the first inner curtain body away from the inner telescopic curtain 32, that is, the slider 321 and the inner telescopic curtain both clamp the first inner curtain body.

[0072] In this technical solution, the gap s between the slider 321 and the side surface (i.e., the inner surface) of the inner telescopic curtain 32 is not greater than the thickness h of the first inner curtain body, so that the gap can be used to achieve the position locking between the inner curtain body and the outer curtain body by facilitating the slight deformation of the curtain body when the slider 321 is in the locked state. Specifically, the slider 321 is pivotally connected to the inner telescopic curtain 32, so that the state switching can be achieved by rotating the slider 321. For example, in the initial state of the slider 321, it is completely in the notch of the second slide groove 311, and pushing and pulling it can drive the inner telescopic curtain to slide left and right. When the slider 321 is rotated 90° by hand, the upper and lower ends of the slider 321 are respectively outside the notch of the second slide groove 311 and pressed on the inner side surface of the first inner curtain body, thereby clamping the first inner curtain body together with the outer side surface of the inner telescopic curtain, thereby achieving the position locking of the inner telescopic curtain.

[0073] See also Fig.10 As shown, the inner telescopic curtain 32 includes a second outer curtain body and a second inner curtain body that are spaced apart, and the slider 321 is disposed on the side of the second inner curtain body. That is, the inner telescopic curtain and the outer telescopic curtain of the telescopic curtain in the present invention are both double-layer curtain body structures, which have higher sealing and heat preservation performance, especially at the position where the two overlap, a four-layer sealing effect can be formed.

[0074] The upper and lower ends of the first outer curtain body and the first inner curtain body are respectively slidably connected to the bottom wall of the top horizontal section 12 and the top wall of the bottom horizontal section 22 through the first slide plate 312 and the second slide plate 313, and the upper and lower ends of the second outer curtain body and the second inner curtain body are respectively slidably connected to the bottom wall of the top horizontal section 12 and the top wall of the bottom horizontal section 22 through the third slide plate 322 and the fourth slide plate 323. The first slide plate 312, the second slide plate 313, the third slide plate 322 and the fourth slide plate 323 are objectively all roughly T-shaped, so as to form an anti-slip sliding connection with the top horizontal section 12 and the bottom horizontal section 22 through the T-shape.

[0075] See also Figures 7 to 9 As shown, a first groove 121 for accommodating the first slide plate 312 and a second groove 122 for accommodating the third slide plate 322 are formed on the bottom wall of the top horizontal section 12. The first groove 121 and the second groove 122 are sequentially arranged along the push-pull direction of the inner telescopic curtain 32. The first slide plate 312 has a hollow slideway 3121 extending along the push-pull direction of the inner telescopic curtain 32, and the bottom wall of the first groove 121 is lower than the bottom wall of the second groove 122, so that after the first slide plate 312 is assembled in the first groove 121, the sliding plane of the hollow slideway 3121 and the bottom wall of the second groove 122 are in the same horizontal plane. For details, see Figure 7As shown, the aforementioned first groove 121 and the second groove 122 are symmetrically constructed on the bottom wall of the top horizontal section 12 and the top wall of the bottom horizontal section 22, respectively. The aforementioned only defines the structure on the top horizontal section 12, and the structure on the bottom horizontal section 22 is not repeated as a symmetrical structure.
