Description

Air intake structure of vertical cabinet air conditioner

technical field

The utility model belongs to the field of electric appliances and relates to an air intake structure of a vertical cabinet type air conditioner.

Background technique

All the air conditioners circulating on the market currently adopt the front air intake mode or the side air intake mode, please refer to Figures 1 and 2, because there is no air intake port on the box shell 12 and the base 11, so the general vertical air conditioner The air inlet can only be placed on the air inlet frame 13 of the front or side, and enters the wind from the air inlet 14 above it. Considering the influence of the cooling capacity, air volume and noise of the air conditioner, the design of the air conditioner has great limitations, and the air intake is limited; and the area of the air inlet must reach a certain amount, and the appearance of the air conditioner is more or less affected by a certain amount. Impact.

Utility model content

The purpose of the utility model is to provide an air intake structure of a vertical cabinet type air conditioner, which provides more options for appearance design and increasing the air intake volume.

In order to achieve the above purpose, the solution of the utility model is: the rear air intake structure of the vertical cabinet type air conditioner, the position of the air inlet is set on the rear box shell, and the front side air intake air guide is provided on the box shell and the base. It is connected with the forward wind guide chamber and the front air outlet, and the rear side air inlet and the front air outlet are connected to the inner cavity of the air duct.

Further, the area of the rear side air inlet can be equivalent to the area of the air inlet of the front air and the side air.

It also includes: an air filter cover net, which is arranged at the rear side air inlet of the air duct and on the rear side box shell, and mainly plays the role of air purification.

The air filter cover net is provided with a movable connector hole, which can be used for the movable connector to pass through and fix.

The position of the air inlet is placed on the rear side of the box shell. Before being sucked into the indoor unit of the air conditioner, part of the air is firstly filtered through the air filter cover on the rear side, and then enters the inner cavity of the air duct from the air inlet on the rear side of the air duct. A part of the air flow is filtered from the integrated box shell and the front air inlet on the base through the guidance of the forward air guide chamber to the front air inlet on the air duct and sucked into the inner cavity of the air duct. The combined airflow of the two parts provides sufficient air volume for the evaporator of the air conditioner for heat exchange, meeting the requirements of cooling performance.

Due to the adoption of the above-mentioned technical scheme, the utility model realizes increasing the air intake in the most convenient way, which is beneficial to the control of production costs, facilitates the management of parts and reduces the noise of the air conditioner, because the air intake in a unit time is the same as that in the air-conditioning room. The motor speed of the machine, the diameter of the fan blade, and the area of the air inlet are related. The technical solution of the utility model enables the same series of air conditioners or several series of air conditioners to use the same type of motor, fan blade and other parts; The increase in air volume can in turn reduce the speed of the motor. The area of the rear air inlet is equivalent to the area of the air intake of the front air and side air. It is more likely to increase the effective air intake area in a specific air conditioner model, which is conducive to reducing purpose of noise.

Detailed ways

As shown in Figures 3 and 4, the rear air intake structure of the vertical cabinet type air conditioner according to an embodiment of the present utility model, the position of the rear air inlet 5 is set on the rear box shell, and the box shell and the base are provided with a front side air intake structure. The air inlet guide port 6 is connected with the forward air guide chamber 4 and the forward air outlet, and the rear side air inlet 5 and the forward air outlet are connected to the inner cavity of the air duct.

The area of the rear side air inlet 5 can be equivalent to the area of the air intake mode of forward wind and side air intake.

It also includes: an air filter cover net 2, which is arranged at the rear side air inlet 5 of the air duct, and is located on the rear side box shell, mainly to play the role of air purification.

The air filter cover net is provided with movable connector holes (such as the central hole 7 ), which can be passed through and fixed by movable connectors (such as screws).

Before being sucked into the indoor unit of the air conditioner, part of the airflow is firstly filtered by the air filter cover 2 on the rear side. The filter cover 2 is an optimized design part in this design scheme. The main consideration is that the airflow can be clean when blown out from the indoor unit of the air conditioner. It is beneficial to human health, and its main function is to purify the air. Screws can be used to fix and connect with the base 1 through the hole 7 in the center; A part of the air flow is filtered from the integrated box shell and the front air inlet 6 on the base 1 through the guidance of the forward air guide chamber 4 to the front air inlet on the air duct 3 and sucked into the inner cavity of the air duct. The combined airflow of the two parts provides sufficient air volume for the evaporator of the air conditioner for heat exchange, meeting the requirements of cooling performance.

The design of the specific shape and size of the rear air inlet 5 needs to comprehensively consider the different requirements of each model. After the rear air inlet 5 is added, the air duct 3, the front air inlet 6 on the base 1, and the forward air guide cavity 4. Changes that are different from the prior art may not be made, as long as each part can be fixedly installed, and will not be described in detail here.

The above description of the embodiments is for those of ordinary skill in the technical field to understand and use the utility model.
