Description

Thread scrap cleaning device and clothes dryer with same

Technical Field

The utility model belongs to the technical field of the dryer, specifically speaking relates to a line bits cleaning device and have device's dryer.

Background

Generally, a dryer is a machine for blowing hot air into a drying drum to dry wet laundry placed in the drying drum. The dryer is substantially similar to a drum washing machine in its appearance, and dries laundry by forcibly circulating hot air into a drying drum via a heater and a blower.

According to a method for treating air generated when laundry is dried, the dryers may be largely classified into a condensation type dryer and an exhaust type dryer.

In the condensation type dryer, air that becomes humid by heat exchange with laundry in the drying drum is circulated without being discharged to the outside of the dryer. The humidified air is heat-exchanged with external air in a separate heat exchanger to generate condensed water, which is discharged to the outside. In the exhaust type dryer, air that becomes humid by heat exchange with laundry in the drying drum is directly exhausted to the outside of the dryer, and a large amount of moisture enters the environment to affect the comfort of the environment.

Compared with an exhaust type clothes dryer, the condensing type clothes dryer is deeply loved by people because the heat exchanger is arranged in the circulating air duct, moisture cannot be discharged to the surrounding environment during working, and the condensing type clothes dryer has little influence on the surrounding environment while drying quickly.

The working principle of the condensation type clothes dryer is as follows: the motor drives the fan to rotate so as to enable air to flow in the closed air channel in an oriented and circulating manner, clothes are washed and dehydrated and then placed into the drum of the clothes dryer, the air enters the drum after being heated by the heating element and carries away water vapor after exchanging heat with the clothes which are rolled and shaken, moisture in the humid air is cooled down when the humid air passes through the heat exchanger, cooling water is pumped into the water storage box through the drainage pump, the air continuously flows to the heating element and enters the drum after being heated, and the circulation is carried out so as to continuously take away the moisture on the clothes until the clothes are dried.

The water circulation system of the traditional condensation type clothes dryer is one-way, water vapor is directly discharged or poured after being cooled, and condensed water is not recycled. Traditional condensation formula dryer installs the filter screen before the heat exchanger for collect the line bits that wear and tear down on the clothing, still can have a small amount of tiny line bits to be passed through the filter screen along with circulation warm braw to heat exchanger department, the line bits of a long time pile up in the wind channel, and the heat exchanger can be because the line bits are piled up and influence the amount of wind, and the bacterium is also multiplied easily to accumulational line bits simultaneously, influences the dryer performance.

After the traditional clothes dryer program cycle is finished, the heat exchanger needs to be cleaned manually, otherwise, the operation of the next program cycle can be influenced, too much thread scraps can obstruct air flow, the energy consumption is increased, the heat exchange efficiency of the heat exchanger is reduced, and frequent alarming and even error reporting of the clothes dryer can be caused. And the filter screen after being cleaned up is reinstalled, and the heat exchanger still needs to be cleaned up once every month, so that the labor and the time are consumed. Along with the continuous promotion of people on the intelligent requirements of the clothes dryer, how to enable a customer to operate more conveniently and simply when using the clothes dryer is a big problem faced by clothes dryer design engineers in various countries.

Chinese patent No. 201410488762.0 discloses a self-cleaning filtering device for a clothes dryer, which comprises a heat exchanger, a filter screen, an air duct, a water storage box, a water storage tank, a water discharge pump, an upper water discharge pipe arranged between the water storage box and the water discharge pump, a water level sensor arranged in the water storage tank, a sprayer arranged in the air duct and positioned between the filter screen and the heat exchanger, and a lower water discharge pipe used for connecting the water storage box and the sprayer; the first sensor is positioned in the air duct and used for sensing the accumulated amount of the thread scraps on the filter screen; and the controller receives signals transmitted by the first sensor and the water level sensor and respectively sends out instructions to control the opening and closing of the drainage pump and the sprayer. This patent is through the line bits that accumulate on sprayer water spray clearance filter screen and the heat exchanger, and the water after the clearance is retrieved and is used for spraying the use next time in the water storage box, does not get rid of the line bits of the aquatic after the clearance, must influence the clearance effect next time, and still need pump the water in the aqua storage tank out in the water storage box just can realize spraying the operation, the process is complicated.

Chinese patent application No. 201680051276.X discloses a clothes dryer in which a cleaning structure of a heat exchanger is improved. The clothes dryer includes: a main body; a drum rotatably provided in the main body; a heat pump including an evaporator, a compressor, a heat exchanger, and an expansion valve, thereby supplying high-temperature dry air into the drum; a condensed water tank configured to receive condensed water generated in the heat pump; and an injection member configured to inject the condensed water in the condensed water tank at the evaporator, wherein the injection member includes: an inlet portion through which condensed water flows; and an injection portion having a guide surface provided such that the condensed water introduced through the inlet portion is uniformly injected on a surface of the evaporator, and wherein at least a portion of the guide surface includes a curved surface having a fixed curvature. This patent is directed to spraying condensate from a condensate tank at the evaporator for cleaning lint and lint that may accumulate on the inlet side of the air flow path to the evaporator, and does not function to clean the heat exchanger.

In view of this, the present invention is provided.
