【発明の詳細な説明】 ［発明の目的］ （産業上の利用分野） 本発明は殺菌機能を有する洗濯機に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a washing machine with a sterilization function.
（従来の技術）
洗濯物を洗濯した場合、大腸菌等の雑菌が死滅せずに洗
濯物に付着したままとなっていることも多い。この場合
、洗濯物を天日に干せば雑菌は死滅するが、しかしなが
ら、天候が良くない場合には、洗濯物を室内あるいは軒
下で干すから雑菌が死滅しないことがある。(Prior Art) When laundry is washed, bacteria such as E. coli often remain attached to the laundry without being killed. In this case, if the laundry is dried in the sun, the germs will die, but if the weather is not good, the germs may not be killed because the laundry is dried indoors or under the eaves.
この対策として、最近、洗濯機においては、洗濯物を湯
により殺菌することが考えられている。As a countermeasure against this problem, it has recently been considered to sterilize the laundry with hot water in washing machines.
即ち、洗濯機本体に貯水槽を設け、この貯水槽内の水を
ヒータにより加熱して、脱水槽あるいは洗い槽に移し入
れるようにし、もって脱水槽内あるいは洗い槽内に収容
した洗濯物を熱湯殺菌する考え方がある。That is, a water storage tank is provided in the main body of the washing machine, and the water in the water tank is heated by a heater and transferred to a spin-drying tank or a washing tank, and the laundry stored in the spin-drying tank or washing tank is heated with boiling water. There is an idea of sterilization.
（発明が解決しようとする課題）
しかしながら、上述の場合、生成した湯を脱水槽あるい
は洗い槽に移し入れるときに、この湯の温度が低下して
しまい、殺菌効果が低下することがある。また、殺菌し
終わって洗濯物を取り出す場合、洗濯物に含まれる湯は
、幾分温度低下してはいるものの、使用者が触れるには
高温度であって、取り出し難いという問題もある。(Problems to be Solved by the Invention) However, in the above case, when the generated hot water is transferred to the dehydration tank or the washing tank, the temperature of the hot water may drop, and the sterilization effect may decrease. Another problem is that when the laundry is taken out after sterilization, the hot water contained in the laundry is still too hot for the user to touch, even though the temperature has dropped somewhat, making it difficult to take out the laundry.
本発明は上記事情に鑑みてなされたものであり、その目
的は、洗濯物に対する殺菌効果を上げることができると
共に、殺菌し終わったときに洗濯物を良好に取り出すこ
とができる洗濯機を提供するにある。The present invention has been made in view of the above circumstances, and its purpose is to provide a washing machine that can increase the sterilization effect on laundry and also be able to take out the laundry well when sterilization is finished. It is in.
［発明の構成］

手段とを設けたところに特徴を有する。[Structure of the Invention] (Means for Solving the Problems) The present invention provides a washing machine body comprising a washing tank, an agitator, etc., and a water storage tank formed in a size that can accommodate laundry; A water tank water supply valve for supplying water into the water tank, a heater for heating the water stored in the water tank, and a device for driving and controlling the water tank water supply valve and the heater for sterilization. A sterilization control means for sequentially executing a first water supply stroke by the water tank water supply valve, a heating stroke by the heater, and a second water supply stroke by the water tank water supply valve when a start command is generated. It has the following characteristics.
（作用）
貯水槽には洗濯物を収容することが可能であり、従って
この貯水槽に殺菌しようとする洗濯物を収容しておく。(Function) It is possible to store laundry in the water tank, and therefore the laundry to be sterilized is stored in this water tank.
しかして、殺菌開始指令が発生すると、殺菌制御手段は
まず第１の給水行程を実行する。この第１の給水行程で

行程では、貯水槽内に給水するから、貯水ｔａ内部の洗
濯物がその水によって冷却される。従って洗濯物を取り
出す場合には、これを容易に取り出すことができる。When the sterilization start command is issued, the sterilization control means first executes the first water supply process. In this first water supply stroke, the water tank water supply valve operates to supply water to the water tank. In the next heating step, the water in the water tank is heated by a heater to produce hot water, and the laundry in the water tank is sterilized with boiling water. In this case, the hot water in the water storage tank is sterilized without being transferred to another tank, so the hot water does not cool down and the sterilizing effect is improved. After this, the sterilization control means executes a second water supply process. In this second water supply step, water is supplied into the water storage tank, so that the laundry inside the water storage ta is cooled by the water. Therefore, when taking out the laundry, it can be easily taken out.

プモータ３１を通電して駆動する。A heating process and a second water supply process are performed in order. First, in the first water supply step, the water tank water supply valve 22 is energized and opened to supply water into the water tank 12, and the water level in the water tank 12 detected by the water tank water level sensor 30 is set to a predetermined water level. When the water supply valve 22 for the water tank is reached, the water supply valve 22 for the water tank is closed.
This completes the first water supply process. In the next heating process, the heater 21 is energized to heat the water in the water tank 12. When the water in the water tank 12 becomes hot water, that is, when it reaches a predetermined temperature suitable for sterilization (
The temperature is detected by the temperature sensor 27), and the pump motor 31 is energized and driven.

容易に取り出すことができる。According to the present embodiment described above, laundry can be stored in the water storage tank 12 and the water stored in the water storage tank 12 can be heated, so that the water generated in the water storage tank 12 can be heated. As a result, the laundry can be directly sterilized, so there is no need to transfer the hot water in the water tank to another tank, and as a result, the hot water does not cool down, improving the sterilizing effect. Further, since the second water supply is performed after the heating process, that is, after sterilization, the laundry in the water storage tank 12 is cooled by the water. Therefore, when taking out the laundry, it can be taken out easily.

。In the above embodiment, the hot water in the water tank 12 is drained at the beginning of the second water supply process before water is supplied.
Even if water is supplied without discharging the hot water, the hot water and the laundry can be cooled, so if the capacity of the water tank 12 is sufficient, the above-mentioned discharging of the hot water can be omitted. Further, the heater 21 may be configured to be attached to the outer surface of the water tank 12 instead of being installed inside the water tank 12.
さらに、貯水槽１２内にに洗濯物収容かご１４を設けた
