Description

A fresh air dehumidification filter device for air conditioning

Technical Field

The utility model relates to the technical field of air-conditioning fresh air system equipment, and more specifically, to an air-conditioning fresh air dehumidification and filtering device.

Background technique

The fresh air system of air conditioner is one of the three major air circulation systems of air conditioner, namely indoor air circulation system, outdoor air circulation system and fresh air system. The main function of fresh air system is to realize the circulation and ventilation between room air and outdoor air, and also to purify the air. The turbid air in the room is discharged to the outside through the fresh air system pipe to form the pressure difference between indoor and outdoor air, complete the air exchange between indoor and outdoor, and refresh the air.

The utility model patent with patent publication number CN216522105U discloses an air-conditioning fresh air dehumidification filter device. By setting a driving device and a cleaning roller, the cleaning roller can move along the lateral direction of the threaded rod, and move back and forth to repeatedly clean the surface of the evaporator. Different from the self-cleaning mode of the evaporator, its cleaning effect is better and will not affect the dehumidification work of the evaporator.

However, in actual use, although this structure can repeatedly clean the surface of the evaporator, when using the filter device, the filter device is generally an integrated structure. When the filter plate needs to be inspected and replaced after long-term use, it is not convenient to separate the filter plate from the filter device.

Utility Model Content

The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. In order to overcome the problems and defects in the existing technology, the utility model provides an air conditioning fresh air dehumidification filter device to solve the problems raised in the above background technology.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-conditioning fresh air dehumidification filter device, comprising a shell, ventilation nets are provided on both sides of the shell, a filter plate is provided inside the shell, a positioning groove is provided on the inner wall of the shell, both ends of the filter plate are located inside the positioning groove, a through groove is provided on the surface of the shell, the through groove is connected with the positioning groove, and one end of the filter plate passes through the through groove and extends to the bottom of the through groove.

It can be seen that in the above structure, outdoor air enters into the shell through the ventilation net, and dust in the air can be filtered through the filter plate to prevent the dust from affecting the normal use of the evaporator.

Preferably, the number of the ventilation nets is set to two, and a cleaning component is provided on one side of one of the ventilation nets;

The cleaning assembly includes a connecting rod arranged inside the shell, one end of the connecting rod is fixedly connected to one of the ventilation nets, a rotating shaft is arranged on the outside of the connecting rod, a fan blade is arranged on the outside of the rotating shaft, and a scraper is arranged on one side of the fan blade.

It can be seen that in the above structure, because it is necessary to circulate outdoor air with indoor air, when outdoor air enters the shell, it will drive dust in, and the dust is easy to adhere to the surface of the filter plate. When there is a lot of dust, it will cause the dust to block the filter plate, affecting the air circulation effect. The airflow generates power on the fan blades, driving the fan blades to rotate, the fan blades drive the rotating shaft, and the rotating shaft drives the scraper to rotate. The scraper can scrape the surface of the filter plate to remove dust on the surface of the filter plate and avoid dust clogging the filter plate, which is beneficial to ensure the air circulation effect.

Preferably, an evaporator is provided on one side of the filter plate, and both ends of the evaporator are fixedly connected to the inner wall of the shell.

Preferably, a fixing rod is provided inside the positioning groove, the number of the fixing rods is set to be multiple, and a rotating wheel is provided outside the fixing rod.

It can be seen that in the above structure, when the filter plate is taken out from the positioning groove, the filter plate fits with the rotating wheel, which can drive the rotating wheel to rotate. The rotating wheel can reduce the friction between the filter plate and the fixed groove, so that the filter plate can be taken out more smoothly, avoiding the filter plate directly fitting with the inner wall of the fixed groove, resulting in greater resistance between the filter plate and the inner wall of the fixed groove, which easily increases the difficulty of taking out the filter plate.

Preferably, a limiting plate is provided at the bottom of the filter plate, the limiting plate is located inside the through slot, and a pull rod is provided at the bottom of the limiting plate.

It can be seen that in the above structure, the bottom of the filter plate can be limited by the limiting plate, the gap between the bottom of the filter plate and the through groove can be reduced, and the filter plate can be driven to move by pulling the pull rod.

Preferably, a clamping plate is provided on one side of the through slot, the number of the clamping plates is set to two, one end of the two clamping plates is provided with bolts, the clamping plates are connected to the shell through the bolts, and a buckle is provided on the other side of the through slot.

It can be seen that in the above structure, when the filter plate is placed inside the fixed groove, the limit plate is pushed to place the limit plate inside the through groove, and the filter plate can be fixed inside the fixed groove by rotating the clamping plate to connect the clamping plate with the buckle. When the filter plate needs to be taken out from the shell, the filter plate can be taken out by separating the clamping plate from the buckle, which is conducive to fixing and disassembling the filter plate.

Preferably, the clamping plate is engaged with the buckle.

It can be seen that in the above structure, when the filter plate needs to be inspected after being used for a long time, the card plate is pulled to separate the card plate from the buckle, and the pull rod is pulled to drive the limit plate to move, so that the limit plate drives the filter plate to move downward inside the fixed groove, and the filter plate can be taken out from the shell.

Technical effects and advantages of the utility model:

1. By disassembling the filter plate, rotating the card plate and separating the buckle, pulling the pull rod, the limit plate drives the filter plate to move inside the fixed groove. Compared with the prior art, the filter plate can be taken out from the shell, which is convenient for inspection and replacement of the filter plate;

2. By setting up a cleaning component, when air enters the shell, it drives the fan blades to rotate, and the fan blades drive the scraper to rotate. Compared with the existing technology, the surface of the filter plate can be scraped to prevent dust from clogging the filter plate and affecting the efficiency of air circulation.
