Description

The invention relates to devices for hand washing and can be used mainly to remove local contamination on textiles, as well as on various permeable materials in everyday life and other conditions, such as field (expeditions, hiking, camps, etc.).

A device for hand washing of linen according to the patent for useful model RU 165855, IPC D06F 15/00, D06F 15/02, publ. 10.11.2016, which can be used for hand washing and rinsing clothes in everyday life, in field conditions (expeditions, hiking, camps, etc.) and for cleaning various permeable materials. The device contains a cylindrical tank for cleaning solution, inside of which is placed a handle in the form of a vertical rod with a perforated disk fixed at the bottom. A foam disk is installed at the bottom of the tank. The tank can be equipped with a lid with a hole for the passage of the handle and a splash guard mounted on the handle. The device provides a pulsed transmission of the cleaning solution through the object to be cleaned, both in the forward and in the reverse direction when the handle moves with the perforated disk up or down, respectively. Foam disk allows you to evenly distribute the flow of liquid through the cleaned object.

For the best effect, it is necessary to make significant efforts, which causes fatigue.

A device for cleaning according to the patent RU 2069244, IPC D06F 15/00, publ. 11/20/1996, which can be used for hand washing of linen, as well as for cleaning the drain pipes of household waste systems from clogging. Device according to RU 2069244 contains a handle, made in the form of a vertical rod with a crossbar in the upper part. The lower part of the handle is equipped with a nozzle in the form of an elastic chamber. Through holes are made in the center of the elastic chamber, and inside the chamber under the holes there is a valve, made, for example, in the form of an elastic plate (crossbar), which covers these holes when pressed on the handle. The elastic chamber is placed in a tank, at the bottom of which a drainage support in the form of a lattice can be installed to reduce the effect of suction of the chamber to the laundry and to intensify the passage of washing liquid through the laundry. A mudguard is installed above the elastic chamber on the handle, which prevents splashing of the washing liquid. The device according to RU 2069244 provides a pulsed transmission of washing liquid through the laundry when the handle is pressed. At the termination of pressure on the handle, the elastic chamber returns to its original position, the valve moves down and opens openings for the passage of a new portion of washing liquid into the cavity of the chamber. And the process is repeated again. The presence of through holes in the wall of the elastic chamber, covered by a valve, eliminates the effect of the camera sticking to the object being cleaned. The device can be freely moved over the entire surface of the object being cleaned. The technical essence of the device according to RU 2069244 closest to the claimed device for hand washing and adopted for the prototype.

The disadvantages of the prototype are increased efforts made to pump the washing solution through the narrow gaps between the elastic chamber and the tank at each pulse, uneven cleaning of laundry in connection with uneven flows of washing solution in different zones, half-wave mode of operation and low pulsation frequency. Also underwear can be clogged elastic chamber. This reduces the efficiency of the washing process.

The technical problem solved by the invention is to increase the efficiency of the washing process and to remove local impurities on the materials being cleaned and to reduce the labor intensity when working with the device for hand washing.

The technical result when using the inventive device, allowing to solve the problem, is to provide a full-wave mode of operation, a uniform flow of detergent through the local area of contamination on clothes and increase the frequency of pulsations when applying cleaning solution, as well as to avoid direct contact of the elastic chamber with the object to be cleaned.

To solve this problem and achieve a technical result, the claimed device for local handwashing, as a device of the prototype, contains a handle with crossbars at the ends and an elastic chamber.

Unlike the prototype, the proposed device further comprises a housing with a perforated lid. The handle is installed in the housing with the possibility of reciprocating movement. The elastic chamber of the claimed device is installed inside the case between the lower crossbar of the handle and the perforated lid and is corrugated. The difference is that the spring is installed inside the elastic chamber, and the body is equipped with a perforated plate that is installed outside on the perforated cover with magnets.

The set of essential features that characterizes the claimed invention is new, since it has not been revealed in known sources of information.

The invention is illustrated by drawings.

FIG. 1 shows a general view of the device in assembled form; FIG. 2 shows a disassembled device; FIG. 3 - the device is a side view, in FIG. 4 shows the device in section along section AA of FIG. 3

The handwashing device consists of a body 1, a movable handle 2, which is able to move downwards under brush compression and upwards when the grip is loosened under the action of spring 3, an elastic corrugated chamber 4, the edge of chamber 4 is firmly pressed between the device’s body and the perforated cover 5 with screws 6, and the upper part of the chamber 4 abuts against the lower crossbar of the handle 2, the removable perforated plate 7 tightly presses the object to be cleaned to the perforated cover 5 with the help of magnets 8 glued in blind holes as in the cover 5, ak and plate 7.

The operation of the device is as follows.

The housing 1 of the device is placed on the permeable surface to be cleaned, a perforated plate 7 is installed on the back side of the surface. The object to be cleaned with the device is placed in a tank with detergent solution. The device handle is moved up and down, providing reciprocating movement of the cleaning solution through the object to be cleaned. When moving the handle down the cleaning solution is displaced from the elastic chamber 4, passing through the object to be cleaned. When the handle 2 moves upwards, the washing solution rushes out of the tank, passing through the holes of the perforated plate 7, the object to be cleaned, the holes of the perforated cover 5 and fills the elastic chamber 4. Thus, a full-wave operation is provided: pulsed washing solution through the object being cleaned , and in the opposite direction. The intensification and efficiency of washing can be increased by increasing the frequency of movements of the handle.
