Description

Technical Field

[0001] The utility model relates to the technical field of design and optimization of air-conditioning systems, and in particular to an internal circulation air-conditioning system which avoids direct suction of external air to improve cooling and heating effects. Background Art

[0002] The indoor unit of the air conditioner is installed indoors and is mainly responsible for regulating and circulating the air. Specifically, the indoor unit of the air conditioner contains a heat exchanger for cooling or heating, and the fan blows the hot and cold air processed by the heat exchanger into the room, thereby achieving the effect of regulating the indoor temperature.

[0003] In traditional air conditioning design, the location and layout of the air inlet and outlet of the air conditioner indoor unit has always been an important design consideration in the industry. Usually, the air inlet and outlet are set in opposite, distant or different directions. For example, the air outlet is usually designed to blow into a large space indoors to better distribute the hot and cold air to the entire indoor space. The air inlet is usually not directly facing the large indoor space, but facing small spaces such as walls, windows or indoor corners.

[0004] The original intention of this design was to ensure air circulation, but this layout also brought some problems:

[0005] 1. Since the air inlet is usually not directly facing the room, but facing the wall or window where the temperature is relatively low, the temperature of the air inlet is quite different from that of the air outlet. When the heat exchanger performs heat exchange, more electricity is consumed.

[0006] 2. The temperature difference between the air inlet and the air outlet is too large, which makes it easier for the air conditioner to start and stop frequently, thus affecting the stability and service life of the air conditioner.

[0007] Therefore, how to optimize the position layout of the air inlet and outlet of the air conditioner indoor unit to reduce the temperature difference between the air inlet and the air outlet and improve the energy efficiency ratio and usage stability of the air conditioner has become a technical problem to be solved by the present utility model.

[0011] The internal circulation air conditioner for avoiding direct intake of external air to improve cooling and heating effects also includes a second shell, the second shell is arranged on the first shell, and an air duct is formed between the second shell and the first shell;

[0012] The air duct includes an air inlet, and the air inlet of the air duct faces the air outlet of the indoor unit of the air conditioner, so that the air inlet and the air outlet on the first shell are closely connected through the air duct.

[0013] As a further solution of the utility model, the second housing is rotatably connected to the first housing so that the second housing and the first housing include a closed position and an open position.

[0014] As a further solution of the utility model, when the second shell is in a closed position with the first shell, one side of the second shell is rotationally connected to the first shell, and a position close to the other side of the second shell is snap-connected to the first shell.

[0015] As a further solution of the utility model, when the second shell is in an open position with respect to the first shell, the second shell is in a flipped-up state to expose the panel of the air conditioner indoor unit to the outside.

[0016] As a further solution of the utility model, the second shell is rotatably connected to the first shell via a hinge.

[0017] As a further solution of the utility model, when the second shell and the first shell are in a closed position, a position of the second shell close to an outer contour of the second shell is sealed and connected to the first shell.

[0018] Compared with the prior art, the beneficial effects of the utility model are: an air duct is constructed on the air-conditioning shell, and the air inlet of the air-conditioning is guided to the air outlet of the air-conditioning through the air duct, thereby achieving a closer connection between the airflow at the air inlet and the air outlet, so that most of the airflow sucked by the air inlet is the airflow at the air outlet, forming an internal circulation structure, avoiding the situation in the prior art where dust is easily circulated and inhaled compared to the method of inhaling from the outside, and achieving not only optimized air circulation, but also significantly reduced the temperature difference between the air inlet and the air outlet, thereby reducing energy consumption during heat exchange, greatly improving the energy efficiency ratio of the air conditioner, and helping to reduce the frequent start and stop of the air conditioner, thereby extending the service life of the air conditioner and enhancing operational stability.

[0032] Embodiment 1:

[0033] The utility model provides an internal circulation air conditioner which avoids direct suction of external air to improve the cooling and heating effects, and the specific structure is as follows:

[0034] The air conditioner comprises an air conditioner indoor unit 1, which comprises a first shell 2, on which an air inlet 3 and an air outlet 4 are conventionally provided. In order to optimize the layout of the air inlet and the air outlet and reduce the temperature difference between the two, the utility model particularly adds a second shell 5.

[0035] The second housing 5 is cleverly arranged on the first housing 2, and a special air duct 6 is formed between the two. The air inlet 3 of the air duct 6 is specially designed to face the air outlet 4 of the air conditioner indoor unit 1, so that the air inlet 3 and the air outlet 4 of the first housing 2 are closely connected through the air duct 6.

[0036] Furthermore, the second housing 5 is connected to the first housing 2 by rotational cooperation, so that the two can be freely switched between the closed position and the open position. When the second housing 5 and the first housing 2 are in the closed position, the two are closely matched to form a complete air duct 6 to optimize air circulation. When necessary, the second housing 5 can be flipped to the open position to completely expose the panel of the air conditioner indoor unit 1 for easy cleaning or maintenance.

[0037] In order to achieve this rotational connection, a hinge connection is adopted between the second housing 5 and the first housing 2, which ensures both the flexibility of rotation and the stability of the connection.

[0038] When the second shell 5 and the first shell 2 are in a closed state, in order to ensure the sealing of the air duct 6 and prevent external air from directly entering, a sealing structure is specially designed near the outer contour of the second shell 5 to ensure a close fit with the first shell 2 to prevent air leakage.

[0039] With this design, the air inlet 3 of the air conditioner indoor unit 1 can directly inhale the air discharged from the air outlet 4 after heat exchange, rather than directly inhaling the air with a lower temperature from the external environment. This can significantly reduce the temperature difference between the air inlet 3 and the air outlet 4, improve the heat exchange efficiency, and thus improve the energy efficiency ratio and use stability of the air conditioner.

[0040] Specifically, this design solves the problem of traditional air conditioner air inlet 3 directly sucking in low-temperature air from the external environment, thereby reducing energy consumption during heat exchange. At the same time, since the temperature difference between the air inlet 3 and the air outlet 4 is reduced, the air conditioner does not need to be frequently started and stopped to maintain the indoor temperature, further improving the service life and stability of the air conditioner.

[0041] The utility model constructs an air duct on the air-conditioning shell, which guides the air inlet of the air-conditioning to the air outlet of the air-conditioning, thereby realizing a closer connection between the airflow at the air inlet and the air outlet, so that most of the airflow sucked by the air inlet is the airflow at the air outlet, forming an internal circulation structure, and avoiding the situation in the prior art where dust is easily circulated and inhaled compared to the method of inhaling from the outside. It not only optimizes the air circulation, but also significantly reduces the temperature difference between the air inlet and the air outlet, thereby reducing the energy consumption during heat exchange, greatly improving the energy efficiency ratio of the air-conditioner, and is conducive to reducing the situation where the air-conditioner is frequently started and stopped, thereby extending the service life of the air-conditioner and enhancing the operating stability.

[0042] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
