げて洗濯効果を上げる。(E) Function When the motor drives the rotor blades for washing, the back blades that act as a pump also rotate, passing the water in the tank from the recess to the water pipe and circulating it between the water pipe and the washing tank. . For this purpose, the motor is cooled with water through a water pipe while rotating, and the circulating water raises the water temperature in the tub to improve the washing effect.

る。(f) Example To explain based on the drawings, 1 is a washing tank installed in a machine frame 2, a dehydration receiving tank 3 is arranged in parallel at the same time, and a recess 4 that becomes a pump chamber is formed in the inner bottom. are doing. Reference numeral 5 denotes a rotor blade disposed in the recess 4, which integrally forms a back blade 6 that performs a pumping action. A motor 7 rotates the rotary blade 5 via a pulley belt and a speed reducer, and the flange of the bracket 8 is fixed to a mounting base 9. 10 is a cooling fan fixed to the motor rotating shaft 11 together with a small pulley.

流の排水管１４に連通させている。 Reference numeral 12 denotes a vinyl water pipe which is tightly wound around the bracket 8 of the motor 7 and is wound many times, one end of which is gathered and extended to communicate with the recess 4 from the peripheral side wall.
The other end is gathered and extended to communicate with the washing tub 1 other than the recess 4. In the embodiment, the drain valve 13 is connected to the drain pipe 14 upstream.

る。 In this way, when water is supplied into the washing tub 1 and washing is performed, as long as the motor 7 is driven and the rotor blades 5 are rotated, the water in the tub is circulated along the path of the recess 4 - the water pipe 12 - the washing tub 1. do. Therefore, the driving motor 7 is always water-cooled, and on the contrary, the heated water raises the water temperature in the tank and improves the cleaning effect. At the same time fan 1
0 sends air into the motor 7 to promote cooling.

る。 In addition, 15 is a centrifugal dehydration tank independently driven by another motor 16, and 17 is an operation unit for controlling and operating each operation of washing, dehydration, water supply, and drainage.

(ト) 考案の効果本考案に依れば、モータを簡便に且つ効率良く
水冷でき、モータ巻線の温度条件等を緩和でき、
モータ自体を低価格で作製できるものである。(g) Effects of the invention According to the invention, the motor can be easily and efficiently water-cooled, and the temperature conditions of the motor windings can be relaxed.
The motor itself can be manufactured at low cost.
