Description
Technical Field
The invention belongs to the technical field of filtering devices, and particularly relates to a filtering device for a heating ventilation air conditioner.
Background
Most heating, ventilating and air conditioning are indoor or related equipment used for processing heating or ventilation and air conditioning in a vehicle, and because the air contains a large amount of fine dust, a filter screen is arranged in most pipelines of the heating, ventilating and air conditioning to prevent the dust from entering the air conditioning, so that the conditions that the circuit inside the air conditioning is poor in contact, or the heat dissipation of a motor is influenced to cause the air conditioning to be damaged and the like are avoided;
and filter screen live time has been of a specified duration can pile up a large amount of dusts on it, treat that the dust is dismantled the filter screen when piling up too much to clear up most processing modes, and this kind of mode is because the filter screen all adorns in the air conditioner depths basically on the one hand, it is too loaded down with trivial details to dismantle the mode, on the other hand, the dust is piled up for a long time and can lead to the circulation of air to be blockked up on the filter screen, consequently should often clear up the filter screen, prevent the filter screen jam in advance, and frequent work of dismantling the filter screen is too loaded down with trivial details, also lead to the filter screen to damage easily.
Most of the existing heating ventilation air conditioner filtering devices do not have a cleaning effect, if the filter screen needs to be cleaned, the filter screen needs to be directly detached, dust on the filter screen is not too much sometimes, the dust can be prevented from being accumulated only by simply cleaning, the mode for detaching the filter screen is too complex, frequent detachment easily causes damage to the filter screen, meanwhile, the filter screen of a part of built-in cleaning brushes is mostly fixedly installed, too much dust is generated on the filter screen, the cleaning brushes can not have a good cleaning effect, and the filter screen is difficult to detach and is an impossible problem.
Disclosure of Invention
The invention aims to provide a filtering device for a heating ventilation air conditioner, and aims to solve the problems that most of the existing filtering devices for the heating ventilation air conditioner do not have a cleaning effect, if a filter screen needs to be cleaned, the filter screen needs to be directly detached, sometimes, dust on the filter screen is not enough, dust accumulation can be prevented only by simple cleaning, the filter screen is detached too complexly, frequent detachment easily causes damage to the filter screen, and meanwhile, most of the filter screens with built-in cleaning brushes are fixedly installed, so that when the dust on the filter screen is too much and the cleaning brushes cannot have a good cleaning effect, the filter screen is difficult to detach and cannot be treated.
The embodiment of the invention is realized in such a way that the filtering device for the heating, ventilation and air conditioning comprises the following components:
the mounting plate is provided with a support frame, and a fixing assembly is arranged between the support frame and the mounting plate;
the filter element is arranged on the fixing assembly, and the fixing assembly is used for fixedly mounting the filter element on the support frame;
the cleaning assembly is arranged between the mounting plate and the support frame and is used for cleaning the filtering piece;
and the linkage assembly is matched with the cleaning assembly and the fixing assembly and is used for controlling the fixing assembly through the operation of the cleaning assembly.
The filtering device for the heating, ventilating and air conditioning, provided by the embodiment of the invention, has the following beneficial effects:
the device combines the movement of the fixed component and the cleaning component by arranging the linkage component, can select different cleaning modes according to different pollution degrees of the filter plate, can drive the cleaning brush to complete simple cleaning work of the filter plate by only directly controlling the operation of the cleaning component when the filter plate only needs simple cleaning, does not need to dismantle the filter plate, is convenient to operate, and can prevent the filter plate from being blocked due to dust accumulation; more is piled up to the dust when the filter, and simple cleaning can't realize when clear effect, and the linkage subassembly is adjusted to the accessible, makes accessible linkage subassembly drive fixed subassembly operation when the subassembly operation is cleaned in control, removes the fixed to the filter, then can dismantle the filter this moment, cleans it comprehensively or changes new filter, convenient operation, and the practicality is strong, and the linkage is good.
