This application is based upon and claims priority to Chinese Patent Application No. 202321999785.9, filed on Jul. 27, 2023, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the technical field of air conditioners, and in particular, to a split window air conditioner.
In the prior art, the indoor unit and the outdoor unit of a window air conditioner are connected by a support. The components between the indoor unit and the outdoor unit, such as electric wire, refrigerant pipe, and water pipe, are usually randomly distributed without being limited, which can easily lead to twisting or bending of the pipes. If the connecting pipe is a plastic pipe, it is easily bent, broken, or compressed during mounting.
In order to solve the problem of easy bending or even breakage of the pipe between the indoor unit and the outdoor unit of the window air conditioner in the prior art, the present disclosure provides a split window air conditioner that realizes accommodation and protection of the pipe.
In order to solve the above technical problems, the present disclosure adopts the following technical solution.
A split window air conditioner includes an indoor unit, an outdoor unit, hoses, and a mounting frame, where a wire or pipe between the indoor unit and the outdoor unit passes through the hose; the indoor unit and the outdoor unit are provided on the mounting frame; and the mounting frame is provided with an accommodating groove for accommodating the hoses.
Further, a cover plate above covers the accommodating groove. The cover plate restricts the movement of the hoses and provides protection for the hoses. The distance between the cover plate and the bottom of the accommodating groove is greater than the outer diameter of the hose to prevent it from being compressed. The outlet for the hoses extending from the cover plate is roughly located above the edge of the window sill, allowing the hoses to bend freely downwards.
Further, there are multiple hoses arranged side by side.
Further, a refrigerant pipe between the indoor unit and the outdoor unit includes a copper pipe joint and a bellows; and ends of the copper pipe joint and the bellows are welded.
Further, the accommodating groove is formed by bending a plate; the cover plate is surrounded by inner flanges; and the inner flange intersecting with the accommodating groove is provided with a secondary flange for avoiding the hose. The cover plate is formed by the flanges around, achieving simple processing and low cost.
Further, the mounting frame includes an internal support connected to the indoor unit; the indoor unit is fixedly provided with a detachable external support for mounting the outdoor unit; the internal support is provided with multiple first through-holes; the external support is provided with multiple second through-holes; the internal support and the external support are connected by a first bolt and a first nut; and the first bolt passes through the first through-hole and the second through-hole in sequence to cooperate with the first nut.
Further, the external support includes a vertical rod; the internal support is provided with a vertical flange; and a distance between the vertical rod and the vertical flange matches a thickness of a window sill.
Further, the mounting frame further includes a first fixing piece that is fixedly connected to the indoor unit; the internal support is provided with at least one first hanging hole; and the first fixing piece is provided with a first hook that hangs from the first hanging hole.
Further, the mounting frame further includes a second fixing piece that is fixedly connected to the outdoor unit; the external support is provided with multiple second hanging holes; the second fixing piece is provided with a second hook that hangs from the second hanging hole; and the second hanging holes are distributed at intervals in a vertical direction on the external support.
Further, the internal support is provided with a shock pad and welded with a fixing nut; the shock pad is connected to a stud that is threaded to the fixing nut; the internal support is further provided with a limiting pipe; the limiting pipe extends into a groove of a window and abuts against a side wall of the groove close to the external support; the limiting pipe is provided with a third through-hole; the internal support is provided with a fourth through-hole; the limiting pipe and the internal support are connected by a second bolt and a second nut; and the second bolt passes through the third through-hole and the fourth through-hole in sequence to cooperate with the second nut. In this way, the position of the limiting pipe is adjustable.
(1) In the present disclosure, the hoses accommodating wires or pipes between the indoor unit and the outdoor unit are accommodated in the accommodating groove. In this way, the wires or pipes between the indoor unit and the outdoor unit are protected from being compressed, excessively bent, or even broken.
(2) The cover plate limits and protects the hoses, and also serves as a support surface to support the up-and-down sliding window.
(3) The mounting frame has a split structure, including the internal support and the external support. The distance between the internal support and the external support is adjustable to adapt to window sills of different thicknesses.
(4) The indoor unit and the outdoor unit are provided on the mounting frame by hanging. A fastening device is provided under the indoor unit and the outdoor unit to ensure secure mounting, ease mounting, and save time.
(5) In the present disclosure, the refrigerant pipe uses a bellows, which features high flexibility and free bending, facilitating the mounting of users.
(6) The refrigerant pipe is formed by welding an outer copper joint to a stainless steel bellows. The production process is simple, and the material is simple and highly reliable. Stainless steel can withstand high temperatures without deformation, effectively avoiding leakage. In addition, the corrugated structural design ensures desired bending performance and toughness. Customers can be assured that there is no risk of hose ruptures for use in a long time.
To describe the technical solutions in the embodiments of the present disclosure more clearly, the following briefly introduces the drawings required for describing the embodiments. Apparently, the drawings in the following description show merely some embodiments of the present disclosure, and those of ordinary skill in the art may still derive other drawings from these drawings without creative efforts.

The technical solutions in embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some, rather than all of the embodiments of the present disclosure. The following description of at least one exemplary embodiment is merely illustrative, and not intended to limit the present disclosure and application or use thereof in any way. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit exemplary embodiments according to the present disclosure. As used herein, unless otherwise specified herein, the singular forms are also intended to include the plural forms. In addition, it should also be understood that when the terms “comprise” and/or “include” are used in this specification, they specify the presence of features, steps, operations, devices, components, and/or combinations thereof.
The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise. Meanwhile, it should be understood that for ease of description, each portion in the drawings is not necessarily drawn to the actual scale. The technologies, methods, and devices known to those of ordinary skill in the art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary, rather than restrictive. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference signs and letters represent similar items in the drawings below. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
It should be understood that in the description of the present disclosure, orientation terms such as “front”, “rear”, “upper”, “lower”, “left”, “right”, “transverse”, “longitudinal”, “vertical”, “horizontal”, “top” and “bottom” indicate orientation or position relationships based on the drawings. Unless otherwise specified, these orientation terms are merely intended to facilitate or simplify the description of the present disclosure, rather than to indicate or imply that the mentioned device or elements must have a specific orientation and must be constructed and operated in a specific orientation.

For ease of description, spatially relative terms, such as “above”, “on the upper side of”, “on the upper surface of” and “on”, can be used to describe the spatial positional relationship between components or features shown in the figure. It should be understood that the spatially relative terms are intended to encompass different orientations of the components in use or operation in addition to those shown in the figure. For example, if a component in the figure is inverted, it is described as a component “above other component or structure” or “on other component or structure”. Therefore, the component will be positioned as “below other component or structure” or “under other component or structure”. Therefore, the exemplary term “above” may include both orientations “above” and “below”. The component may also be positioned in other different ways (rotated by 90 degrees or in other orientations), but the relative description of the space should be explained accordingly.
In addition, it should be noted that the use of words such as “first” and “second” to define parts and components is only for the convenience of distinguishing corresponding parts and components. Unless otherwise stated, the above words have no special meaning, so they should not be construed as a limitation on the protection scope of the present disclosure.
As shown in
Refrigerant pipe 10 is provided between the indoor unit 1 and the outdoor unit 2 to transport a refrigerant. Traditional connecting hoses are usually made of plastic such as nylon, as shown in
In addition, traditional smooth connecting pipes are not easy to bend during mounting, with low toughness and small bending radius, making them easily break and compress due to large external forces. Increasing the toughness requires reduction in the hardness of the hose, but this can also cause the connector to leak easily.
As shown in
The bellows 102 can also be made of nylon or Teflon for the refrigerant transport of the split mobile air conditioner. The structure of the bellows 102 avoids the traditional form of smooth connecting pipe. The bellows 102 solves the drawbacks of smooth connecting pipes. The bellows 102 features high flexibility, free bending, and easy mounting for users. It can be made of materials with high hardness, greatly increasing the compressive resistance.
