Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of a clothes dryer including a heat exchanger cleaning device for the clothes dryer according to an embodiment of the present invention. As shown in fig. 1, a filter screen is provided in a circulation duct between an inner tub and an evaporator in the dryer for filtering dirt in air blown from the inner tub. The electrostatic balls are arranged between the filter screen and the evaporator and used for adsorbing residual dirt penetrating through the filter screen after being blown by air passing through the filter screen to be in contact with the evaporator to generate static electricity. In this embodiment, the electrostatic ball may adsorb residual dirt in the air, and may also adsorb residual dirt adhered to the surface of the evaporator.
During the operation of the clothes dryer, dirt (such as thread scraps, dust and the like) is carried in the medium-temperature and high-humidity air blown out from the inner barrel, when the dirt reaches the filter screen through the circulating air duct, a part of the dirt is blocked by the filter screen, and a part of residual dirt still passes through the filter screen. The electrostatic ball is blown by air to contact with the evaporator to generate static electricity due to friction, so that residual dirt penetrating through the filter screen is adsorbed. The medium-temperature high-humidity air reaches the condenser after being cooled and dehumidified by the evaporator, and is blown into the inner barrel after being heated by the condenser. The evaporator adopts a refrigerant to cool and dehumidify the medium-temperature high-humidity air, the refrigerant reaches the condenser through the compressor and the exhaust sensor, the condenser heats the air through the refrigerant, and the refrigerant flows back to the evaporator through the capillary tube.
Fig. 2a-2b are schematic cross-sectional views of an electrostatic ball according to an embodiment of the present invention. Alternatively, as shown in fig. 2a, the electrostatic ball is filled with gas, and includes an insulating layer for wrapping the gas and bristles arranged outside the insulating layer, and the gas is used for supporting the insulating layer to form a ball shape. The benefit of filling the electrostatic bulb with gas is that the electrostatic bulb is lighter and can be blown by air to contact the evaporator. Specifically, after the electrostatic pellet is blown by air, the insulating layer wrapping the air is in rolling contact with the surface of the evaporator, and static electricity is generated due to friction action to adsorb residual dirt in the air. Moreover, due to the friction between the static small balls and the surface of the evaporator, the bristles on the outer side of the insulating layer can clean residual dirt attached to the surface of the evaporator and then adsorb the dirt by the static insulating layer.
Optionally, as shown in fig. 2b, the electrostatic ball includes a solid foam ball, an insulating layer wrapping the solid foam ball, and bristles disposed outside the insulating layer.
The insulating layer can be a plastic layer or a silicon rubber layer, and the thickness of the insulating layer is smaller than a set threshold value. The set threshold may be in the millimeter range. The material of the solid foam balls can be Polystyrene foam (EPS). The bristles can be made of animal hair, plastic or silica gel. The advantage of arranging the brush hairs outside the electrostatic ball is that the evaporator can be cleaned while adsorbing residual dirt.
Optionally, fig. 2c is a schematic front view of an electrostatic ball according to an embodiment of the present invention. As shown in fig. 2c, the electrostatic ball includes a solid foam ball and an insulating fiber filament wound around the solid foam ball.
Wherein, the insulating fiber filaments can be wound around the foam solid ball in an irregular mode. The insulating fiber yarn can be plastic fiber yarn or silicon rubber fiber yarn. The material of the foam solid ball can be polystyrene foam. Specifically, after the electrostatic small balls are blown by air, the insulating fiber yarns wound around the foam solid balls are in rolling contact with the evaporator, and static electricity is generated due to friction so as to adsorb residual dirt in the air. Moreover, due to the friction between the electrostatic globule and the surface of the evaporator, the insulating fiber yarn can clean the residual dirt attached to the surface of the evaporator and then adsorb the dirt.
In this embodiment, when a large amount of dirt is accumulated on the electrostatic ball, the front end cover of the evaporator can be opened to take out the electrostatic ball for cleaning, and the electrostatic ball is put back into the clothes dryer after cleaning.
The embodiment of the utility model provides a heat exchanger cleaning device for clothes dryer, include: a filter screen and a plurality of electrostatic balls; the filter screen is arranged in a circulating air duct between the inner barrel and the evaporator in the clothes dryer and is used for filtering dirt in air blown out by the inner barrel; the electrostatic balls are arranged between the filter screen and the evaporator and used for adsorbing residual dirt penetrating through the filter screen after being blown by air passing through the filter screen to be in contact with the evaporator to generate static electricity. The heat exchanger can be cleaned, the phenomenon that the evaporation efficiency is affected due to excessive dirt on the surface of the evaporator is avoided, and the cost can be reduced.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
