Definitions

• the present application refers to a pressurizer device for a clothes washing machine and, more specifically, a pressurizer device capable of increasing water input rate in a clothes washing machine.
• the process of washing clothes with an automatic washing machine basically comprises the operations of filling up a tank with water and wash liquid (e,g. detergent), stirring clothes with a stirrer to effect washing, draining water with detergent, again filling up with wash liquid, stirring clothes to remove detergent (rinsing step), draining water, and centrifuging clothes to remove exceeding water.
• wash liquid e,g. detergent
• Water supply rate at a machine installation local directly impacts on the time needed to fill up a tank with water. It is common that, mainly in Brazil and in other developing countries, consumers' residential building installations comprise low-height water reservoirs, and, consequently, with low pressure. Because of that, filling up a tank of a clothes washing machine occurs in a substantially slow mode.
• This slowness in this filling step may cause problems related to the machine program and supplies delivery.
• Some solutions known in the art to deal with this kind of problem involve increasing water supply hose diameter of a washing machine or using more than one water supply hose for a washing machine.
• one of the objects of the present invention is to provide a pressurizer device for use in a clothes washing machine capable of increasing water supply rate of a wash tank whereby the time required for filling is reduced.
• a further object of the present invention is to provide a pressurizer device for use in a clothes washing machine of easy installation and which can be installed in the machine by the own user.
• a pressurizer device for a clothes washing machine of the type comprising a water inlet for feeding water to a wash tank, said device comprising:
• the water inlet connection is directly attached to the water supply network. Nevertheless, in alternative embodiments, said water inlet connection can be attached to the water outlet of the water supply network through a hose.
• the water outlet connection is directly connected to the water inlet of the clothes washing machine while in alternative embodiments, the water outlet connection can be attached to the water inlet of the clothes washing machine through a hose.
• the pressurizer device comprises a carcass housing a rotor and an electric motor, wherein the water inlet connection and water outlet connection are disposed in said carcass.
• the present invention also contemplates a clothes washing machine of the type comprising a wash tank and a water inlet for feeding water to said wash tank, said machine further comprising a pressurizer device disposed between the machine water inlet and a water outlet of water supply network in the machine installation local.
• said pressurizer device comprises:
• a carcass housing a rotor and an electric motor
• Said water outlet connection can be directly attached to said water supply network water outlet or a hose can be used.
• the water outlet connection can be directly attached to the water inlet of the clothes washing machine or a hose can be used.
• Figure 1 shows a perspective view of a preferred embodiment of the pressurizer device of the present invention.
• FIG. 2 shows an exploded perspective view of the preferred embodiment of the pressurizer device of the present invention.
• a conventional clothes machine comprises a water inlet connected to a water valve inside said machine.
• the water inlet is connected to the water outlet of the consumer's water network by means of a water hose.
• the filling time and speed of the machine wash tank depend directly on the features of the consumer's house water supply system.
• the building installation type places a water reservoir in an extremely low height, whereby water ends up reaching the tap with low pressure.
• this low pressure does not allow for the tank to be suitably and appropriately filled up.
• washing supplies e.g. detergent and conditioner
• the present invention provides for a pressurizer device 10 to be installed between the machine water inlet and water supply network water outlet, wherein said device 10 pressurizes the water before it enters the inner water valve, thereby ensuring that the washing liquid is suitably filled and also washing supplies are suitably delivered.
• said device 10 of the present application comprises a carcass 20 housing a rotor 30 and an electric motor 40.
• Said carcass 20 comprises a water inlet connection 60 and a water outlet connection 50.
• Said water inlet connection 60 is attached to said water supply network water outlet and said water outlet connection 50 is attached to the water inlet of the clothes washing machine.
• the water inlet connection is directly attached to said supply network water outlet (for example, it is directly attached to a tap). Nevertheless, said water connection 60 can be connected to the water outlet by means of a hose.
• the water outlet connection 50 can be directly attached to the machine water inlet.
• said water connection 50 can be attached to the water outlet by means of a hose.
• said pressurizer device In a preferred embodiment illustrated in figures, said pressurizer device
• water coming from an installation local supply network of the washing machine enters the pressurizer device through connection 60, is pressurized by means of a rotor 30, exits said device through the outlet connection 50 and goes into the washing machine water inlet.
