Description

Technical Field

[0001] The utility model relates to an indoor unit of a cabinet air conditioner, belonging to the technical field of air conditioners. Background Art

[0002] At present, air conditioners generally adopt a split structure, which consists of an indoor unit and an outdoor unit, and are installed indoors and outdoors respectively, and are connected by pipelines and wires in the middle. In addition, condensate water will be generated when the air conditioner works, and a drain pipe for discharging condensate water usually needs to be provided. Therefore, an outlet pipe opening for the connection pipes and the drain pipe between the indoor and outdoor units to pass through needs to be opened on the outer shell of the indoor unit.

[0003] Referring to the patent documents with publication numbers CN207422429U and CN202216375U, for a cabinet air conditioner, the outlet pipe opening in the prior art is generally arranged at the rear or the rear side of the bottom of the outer shell through a detachable rear decorative panel. During installation and use, external pipelines such as the connection pipes and the drain pipe between the indoor and outdoor units pass through the outlet pipe opening and then pass through the air conditioner installation hole reserved on the wall of the user. However, in the actual implementation process, for the convenience of later installation and connection, the external pipelines are usually connected to the indoor unit at the factory. During packaging and transportation, the external pipelines can only be coiled outside the air conditioner shell. And in order to prevent the external pipelines from scratching the air conditioner panel, multiple layers of protective films usually need to be wound on the external pipelines as protective measures, which is cumbersome to operate. Moreover, a foam packaging cushion usually needs to be designed in the packaging box. The foam packaging cushion needs to consider the reserved accommodation grooves for the external pipelines. Manually coiling the external pipelines of the air conditioner outside the shell is random, and it is difficult to unify the standards, which increases the design difficulty of the foam packaging cushion. In addition, when displayed for sale in a shopping mall, the external pipelines are exposed, which is not only unsightly but also easily damaged. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an indoor unit of a cabinet air conditioner, which can be more convenient for packaging, transportation, sales and display.

[0005] The technical solution adopted by the present utility model to solve the above technical problems is as follows: The indoor unit of a cabinet air conditioner includes a housing and external pipelines. The external pipelines include an indoor and outdoor unit connecting pipe and a drain pipe. An outlet is provided at the rear of the bottom of the housing, or at the rear side of the bottom, or at both of the above positions simultaneously. The outlet is provided on a detachable rear decorative panel in the housing. The inner ends of the external pipelines are arranged inside the housing, and the outer ends of the external pipelines have a first state of passing through the outlet. A wire passing channel matching the external pipelines is provided in the inner side area of the housing at the inner end of the outlet. An annular groove is provided along the circumferential direction of the bottom of the outer wall of the housing below the outlet. The upper edge of the annular groove is communicated with the wire passing channel. The external pipelines have a second state of being coiled in the annular groove. A bottom decorative panel for covering the external opening thereof is provided on the outer end face of the annular groove, and the bottom decorative panel is detachably connected and installed on the housing.

[0006] Further preferably: The bottom decorative panel is composed of a bottom first decorative panel located at the front side of the housing and a bottom second decorative panel located at the rear side of the housing, and the rear decorative panel and the bottom second decorative panel are of an integral structure.

[0007] Further preferably: The indoor and outdoor unit connecting pipe and the drain pipe share the same outlet.

[0008] Further preferably: The outlet is provided with a detachable protective plate.

[0009] Further preferably: The housing includes a housing main body and a base, the base is detachably connected to the housing main body, and the outlet is provided above the base; the annular groove is formed by combining the upper outer side wall of the base and the bottom end face of the housing main body.

[0010] Further preferably: The height distance between the lower edge of the outlet and the upper end face of the base is not less than 8 cm.

[0011] The beneficial effects of the present utility model are as follows: When the air conditioner is in packaging, transportation or sales display, the external pipelines can be coiled in the annular groove and covered by the bottom decorative panel. The external pipelines are completely hidden inside the housing and are not easily damaged. The foam packaging cushion only needs to be correspondingly designed according to the air conditioner housing, which has better versatility and reduces the difficulty of packaging and transportation.

[0017] Component markings in the figure: housing 1, external pipeline 2, outlet pipe 3, wire passing channel 4, annular groove 5, bottom trim panel 6, base 7, heat exchanger 8. Specific embodiments

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As Figures 1 to 5 shown, the present utility model includes a housing 1 and an external pipeline 2. The external pipeline 2 includes an indoor and outdoor connection pipe and a drain pipe. An outlet pipe 3 is provided at the rear or the side rear of the bottom of the housing 1, or at both of the above two positions simultaneously. The outlet pipe 3 is provided on a detachable rear trim panel in the housing 1. The inner end of the external pipeline 2 is arranged inside the housing 1, and the outer end of the external pipeline 2 has a first state of passing through the outlet pipe 3 (this state is shown in Figure 1 , corresponding to when the user installs and uses). An area on one side of the inner end of the outlet pipe 3 inside the housing 1 is provided with a wire passing channel 4 that matches the external pipeline 2. The bottom of the outer wall of the housing 1 is provided with an annular groove 5 along its circumference below the outlet pipe 3. The upper edge of the annular groove 5 is communicated with the wire passing channel 4. The external pipeline 2 has a second state of being coiled in the annular groove 5 (this state is shown in Figures 2 to 5 , corresponding to when packaging, transporting or displaying for sale). A bottom trim panel 6 for covering the external opening thereof is arranged on the outer end surface of the annular groove 5. The bottom trim panel 6 is detachably connected and installed on the housing 1. Specifically, for the detachable connection of the rear trim panel and the detachable connection of the bottom trim panel 6, conventional snap connection structures, screw connection structures, combinations of snap connection and screw connection, etc. can be used to achieve.

[0020] It can be understood that the arrangement mode of the bottom trim panel 6 is adapted to the structure of the annular groove 5. Generally, multiple unit plates can be spliced into an annular structure. In order to simplify the connection structure, one plate can be designed into two pieces. More specifically, the bottom trim panel 6 is composed of a bottom first trim panel located on the front side of the housing 1 and a bottom second trim panel located on the rear side of the housing 1. In this embodiment, the rear trim panel and the bottom second trim panel can be preferably designed as an integral structure to further simplify the connection structure. In some alternative embodiments, the rear trim panel can also be independently provided.

[0021] To further facilitate installation, packaging, and transportation, the connecting pipes and drain pipes for the indoor and outdoor units can preferably be designed to share the same outlet 3. In some alternative embodiments, the connecting pipes and drain pipes for the indoor and outdoor units can be routed separately according to the actual situation.

[0022] To better protect the internal structure of the air conditioner, the outlet 3 is provided with a detachable protective plate. When the air conditioner is not installed and in use, the outlet 3 can be blocked by the protective plate. The detachable feature of the protective plate can be achieved by conventional snap connection structures, screw connection structures, a combination of snap connection and screw connection, etc., or by a disposable tearable structure.

[0023] Users usually reserve air conditioner installation holes in advance before installing the air conditioner. The external pipelines 2 such as the connecting pipes and drain pipes for the indoor and outdoor units extend from the bottom of the cabinet air conditioner, and the position may be lower than the air conditioner installation holes pre-drilled in the user's home. Such a height difference may cause poor circulation of the refrigerant or condensate in the external pipeline 2, especially the discharge of condensate, which generally relies on gravity to drain out by itself through the condensate pipe. To improve the versatility during installation, the housing 1 includes a housing main body and a base 7, and the base 7 is detachably connected to the housing main body. The outlet 3 is provided above the base 7; in this way, the user can replace the base 7 with a suitable height according to the situation. To improve the overall decorative performance of the air conditioner and facilitate processing and assembly, the annular groove 5 in this solution is preferably formed by the combination of the outer side wall of the upper end of the base 7 and the bottom end surface of the housing main body. In this embodiment, a further preferred solution is that the height spacing between the lower edge of the outlet 3 and the upper end surface of the base 7 is not less than 8 cm. In this way, no matter which height of the base 7 is replaced, there is a certain distance from the ground, which is convenient for the user to clean.
