Description

Hot air drying system for washing machines that allows for uniform hot air supply and injection while effectively discharging humid exhaust}

The present invention relates to a hot air drying system for a washing machine that is capable of supplying hot air evenly and effectively discharging moist exhaust. More specifically, it allows smooth washing of various laundry items such as various clothes and various textiles. When drying laundry, the inflow of hot air makes it possible to dry the laundry by supplying it in a certain direction or by introducing hot air at various angles. In addition, it is possible to separate the moisture contained in the laundry by rotating it through the washing machine. The rotating protrusion rotates the laundry on its own through collision with the laundry, enabling efficient drying, and enables uniform hot air supply to quickly exhaust moisture generated from the laundry, while effectively discharging humid exhaust. This is about a hot air drying system for a washing machine.

Typically, washing machines allow various laundry items, such as clothes and textiles, to be conveniently washed using a mechanical device rather than washing them by hand. However, in the case of these washing machines, there is a dehydration function to quickly dry the laundry after the washing is finished, so it can be operated until a certain amount of moisture is removed, but complete drying is not possible, and even if a separate drying function exists, it is not effective. It is common for problems such as long drying times to occur due to insufficient drying time.

For example, according to Korea Registered Utility Model No. 0155403, 'a passage 410 consisting of an inlet 411 and an outlet 412, and a motor 420 inside the passage 410 are used to pump outside air. A typical dryer washing machine is composed of a blower fan 430 that forcibly suctions and blows air at the same time, and a heat exchanger 440 that exchanges cold air blown to the rear of the blower fan 430 with high-temperature heat. In this case, a sealing plate 510 is installed on one side of the discharge port 412 of the passage 410 to penetrate one side of the passage 410, and one end of the sealing plate 510 is installed at the bottom of the suction port 411. A synchronous motor 530 connected to the wire 520 is installed, and a return spring 540 connected to the front end of the sealing plate 510 is installed on the other side of the discharge port 412 to control the airflow rate. We present a ‘laundry drying device for a drying washing machine,’ which is characterized by forming (500).

However, the laundry drying device of the dryer washing machine is configured to control the blowing amount by simply blocking hot air, so it cannot supply hot air in various directions, which may limit drying efficiency.

Another example, according to Korean Patent No. 1706663, is 'cabinet; a tub disposed inside the cabinet; a drum rotatably disposed inside the tub; A drying device that heats and circulates air discharged from the tub to dry the laundry in the drum, the drying device comprising a drying duct in which a heater for heating air is located, and a drying duct inside the tub and the drying duct. a drying device including a circulation passage through which air circulates, and a suction member coupled to one side of the drying duct and introducing air outside the tub into the circulation passage; a discharge member coupled to the upper part of the tub and discharging some of the air in the circulation passage to the outside of the cabinet; It includes a drain pump located at the bottom of the tub, wherein the discharge member is provided at the top of the discharge member and has a first inlet through which the air flows, and is provided at the bottom of the discharge member and is discharged by the drain pump. A drum washing machine is provided, characterized by a second inlet through which pumped washing water flows, and an outlet located between the first inlet and the second inlet for discharging at least one of air and washing water.

However, the above-mentioned drum washing machine also simply supplies hot air and does not have a structure that enables rapid drying of laundry, so drying efficiency is low and drying time is long, which can often occur.
