Description

The present invention relates to a washing machine or a machine for washing and drying laundry. In general, this invention relates to laundry machines in which a wash cycle of a quantity of laundry is implemented, and washing-drying machines in which a wash cycle of a quantity of laundry is followed. a drying cycle of this laundry. It concerns both loading machines, laundry from above, an opening in the upper part of the machine, and machines for loading the front load, through an opening in the front of the machine.

Such a washing machine or washing and drying machine comprises a washing tub and a drum rotatably mounted about an axis of rotation in this tank. The axis of rotation can be horizontal or inclined. The laundry to be washed is placed in the drum which has a perforated ferrule to allow the flow of water during the different phases of the laundry cycle. In addition to the laundry circuit, the washing and drying machines include a drying ventilation circuit. This drying air circuit generally comprises an air circulation duct in communication with the drum in which the laundry is placed. The drum thus constitutes one of the elements of this drying ventilation circuit. The water supply of the network of a washing and drying machine is carried out by several solenoid valves. One or more solenoid valves supply a detergent box with water from the network during the laundry cycle. And another solenoid valve supplies water to the water condenser.

A water supply line connects one of the solenoid valves to the water condenser. The detergent box is fed by three solenoid valves when the distribution of water from the network in said detergent box is carried out by crossed jets allowing the flow of detergent products into the washing tank.

Said three solenoid valves are used to supply water to the network box for washing products. A first solenoid valve is used to supply water to the box for washing products to release the prewash product into the wash tank. A second solenoid valve is used to supply the water to the box for washing products to release the detergent into the wash tank. A third solenoid valve is used to supply water to the box for washing products to release the softener into the wash tank. Two solenoid valves can also be opened simultaneously to supply the box with water for washing products in order to release bleach into the wash tub. The other solenoid feeds water from the network a water condensation ramp at a lower flow rate than said three solenoid valves described above. Also known are machines for washing and drying laundry comprising a device using water supplied with water by a water reserve filled by a user. However, these washing and drying machines have the disadvantage of regularly fill a water reserve by a user and have a cumbersome access area on the body of these machines to said water supply. The device using water from these washing and drying machines requires to be supplied with water from the network by a water supply pump or by a water supply valve. However, the water supply pump of the water-using device does not operate by directly connecting it to the water supplying the washing and drying machine because of the high pressure of the water supply system. water, generally of the order of 4 bars. In addition, the use of a water supply valve of the device using water does not make it possible to provide a water supply with a low water flow, generally less than 100 g / minute. The object of the present invention is to solve the aforementioned drawbacks and to propose a machine for washing or washing and drying laundry supplying water to the network two devices using water from a water supply valve of the common network. .

In addition, the second device using water is automatically supplied with water from the network via a network water storage tank and a water supply pump without the user having to fill a reserve of water. Furthermore, a washing or washing and drying machine according to the invention makes it possible to reduce the size of the water storage tank of the network by filling said water storage tank with the network as a function of the water consumption of the second device using water through the first water supply valve of the network. The supply of water to a hydraulic circuit of the machine from a first water supply valve of the network makes it possible to feed on the one hand a first device using water and on the other hand a second device using some water. In this way, a first water supply valve of the network makes it possible to distribute the water of the network to two different members of the hydraulic circuit of the machine, the two members of the hydraulic circuit having different functions in the machine. The use of a single water supply valve of the network connecting the machine to the water system with two elements of the hydraulic circuit makes it possible to reduce the costs of obtaining a washing or washing and drying machine. the laundry and to minimize the space required for the water supply of the network of the machine.
