Description

Catkin preventing structure for traditional flat-plate external machine Technical Field The utility model relates to the technical field of catkin prevention of a flat-plate external machine, in particular to a catkin prevention structure for a traditional flat-plate external machine. Background The traditional flat-panel external machine mainly comprises a shell, a condenser, a fan and other components. The condenser is directly exposed on the surface of the external machine, and when the fan operates, air directly flows through the condenser to perform heat exchange so as to assist the external machine to dissipate heat. Due to the lack of protective measures, in the season of the catkin fluttering, the open design makes the outer machine at the during operation, and a large amount of catkin in the surrounding air can be adsorbed very easily by the suction that the fan produced and pile up on the air inlet face of condenser, and this can seriously hinder the normal circulation of air, influences the normal operating of outer machine, reduces the heat exchange efficiency of condenser for the refrigeration or the heating effect of air conditioner is discounted greatly, increases the energy consumption. Moreover, long-term accumulated catkin can also cause corrosion and damage of the condenser, shortening the service life of the external machine. In addition, the catkin attached to the condenser is complicated in operation and high in difficulty, and professional maintenance personnel are often required to detach and clean the catkin, so that the time and money of a user are consumed, and the foreign machine is damaged to a certain extent due to frequent detachment. In order to solve the technical defects, a structure for preventing catkin of a traditional flat-plate external machine needs to be designed. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a catkin preventing structure for a traditional flat-plate external machine. The structure for preventing the catkin of the traditional flat plate outer machine comprises a catkin prevention filter screen and two supporting baffle strips used for fixing the catkin prevention filter screen, wherein the supporting baffle strips comprise two fixing strips and one connecting strip, one side of one fixing strip is fixed with one side of the connecting strip, the other side of the connecting strip is fixed with one side of the other fixing strip to form a Z-shaped long strip, one ends of the two fixing strips are provided with flanging, the flanging directions and the positions are opposite, one fixing strip is fixed on an air inlet surface of a condenser of the traditional flat plate outer machine by adopting a first screw, and the catkin prevention filter screen is inserted into the other fixing strip until one side of the catkin prevention filter screen is abutted against the flanging, and the other side of the catkin prevention filter screen is fixed by adopting a second screw. Still further, prevent catkin filter screen includes filter screen braced frame and sets up the filter screen layer on filter screen braced frame, the filter screen layer includes inlayer net, sets up the laminating net in inlayer net both sides.
