Description

 SYNTHETIC GRANULATED DETERGENT AND SHOWER CABIN FOR ITS USE.

The present invention relates to the design of synthetic granular detergent (GHS) and to sanitary-hygienic equipment, in particular to shower cabins that use GHS. The closest to the proposed detergent by the number of essential features is a synthetic granular detergent, each granule of which is made in the form of a base equipped with a detergent / A.s. USSR M> 910760, IPC 3 C12D 11/02, 1980 /. Mentioned GHS is obtained by preparing an aqueous solution of GHS components - surface-active substances (surfactants) and sodium tripolyphosphate (TPPF), spray drying the resulting solution, followed by supply of hot granules and finely divided TPPN to the cooling zone.

The disadvantage of this tool is the lack of strength and density of the granules, which limits its scope only to conditions of small static loads.

The closest to the proposed shower cabin by the number of essential features is the shower cabin, which contains a base tray with a drain, on which vertical walls are installed, which limit the space for washing, as well as a shower nozzle provided by the control panel - / Shower Colisei K-7008 submitted May 22, 2006 on the Internet page www.wipdsdom.ru/.

The disadvantage of this shower is the lack of means in it to intensify the washing process, in particular, the user is forced to independently use such accessories as washcloths and soap to intensify the process of washing his body. The use of such additional accessories is not always possible, for example, by persons with disabilities with limited functions of the organs of motion, sick, weakened people and people of advanced age.

The basis of the proposed inventions is the task of creating such a GHS and shower, which would allow to intensify the washing process of the human body through the use of GHS increased strength and the possibility of their automatic use in the shower by users with limited functions of the organs of movement.

The problem is solved in the proposed synthetic granular detergent, in which, as in the well-known synthetic granular detergent, each granule is made in the form of a base equipped with a detergent, and, according to the invention, the basis of each GHS granule is made of an elastic material with open porosity, for example from foam rubber, and impregnated with a liquid detergent.

A feature of the proposed GHS is the fact that each granule has a shape close to the shape of a sphere with a diameter of D = 2.0 ... 12.0 mm.

A feature of the proposed GHS is that shampoo or liquid soap is used as a liquid detergent.

As additives to liquid detergents, liquid substances such as relaxants, reducing agents, dermatological preparations, flavorings, stimulants, specific detergents, cosmetic preparations, and pharmaceutical preparations can be used based on the medical, hygienic, or other needs of the user.

The problem is solved in the proposed shower, which, like the well-known shower, contains a base tray with a drain, on which there are vertical walls that limit the space for washing, as well as a shower unit, which includes a washing nozzle designed to be fed through it the washing medium on the user's body and the control panel for temperature and pressure of the washing medium, and, in accordance with the invention, the shower unit is supplemented by a storage tank designed to accommodate synthetic granules lated detergents described above (GHS) connected through an Archimedean screw with the first input of the mixing vessel, which is designed for filling it with liquid detergent and impregnating these GHS substance, the second input of the mixing tank is provided with valves and is designed to connect it to the water supply network, the output of the mixing tank is connected to the input of a centrifugal pump, the output of which is connected by a flexible pipe to the washing nozzle installed with the possibility of its movement and fixing in the washing space, and the drain provided with devices for the separation and push-up of the GHS and their re-supply to the mixing tank.

A feature of the proposed shower is that the separation device is made in the form of a perforated gutter slanted under the drain. A feature of the proposed shower cabin is that the device for squeezing the GHS is made in the form of a centrifuge, the entrance to which is connected to the lower end of the gutter installed under the drain, and the outlet of the centrifuge is connected to the inlet of the centrifugal pump.

A feature of the proposed shower is that it is equipped with a device to protect the human head from water and GHS during washing, which is made in the form of a disk with an adjustable diaphragm opening, designed for sliding position on the person’s neck while washing the body.

A feature of the proposed shower is that the shower is equipped with at least one emergency switch for supplying water and GHS to the washing nozzle.

A feature of the proposed shower is that the washing nozzle is provided with a drive designed to move it along a helical line around a vertical axis, and the outlet of the washing nozzle is directed to the center of the washing space.

The invention is illustrated in the schematic drawings, where in FIG. 1 shows the design of the proposed GHS; in FIG. 2 shows the proposed shower.

Each GHS-granule 1 includes a base made of a flexible material with open porosity - foam, which meets the standards

DSTU ISO 9000-2001 (Manufacturer "York", Poland). The basis of each granule 1 is impregnated with a liquid detergent - liquid soap. Each granule 1 has a shape close to the shape of a sphere with a diameter of D = 2.0 ... 12.0 mm. The diameter D is selected from such conditions: a decrease in D of less than 2.0 mm requires a significant increase in water pressure to create a comfortable washing process of the desired intensity, which is not economically justified due to the need to use an additional pump. Increases in D of more than 12.0 mm at existing water pressures in urban water supply networks in Ukraine can lead to consumer injury due to the rather large mass of GHS 1. The use of granules 1 in a shape close to the shape of a sphere is the most technologically advanced.

The shower cabin contains a base tray 2 with drain 3. Vertical walls 4 are installed on the base tray 2 to limit the space with the volume needed to wash one person. The shower cabin also contains a shower unit, which includes a washing nozzle 5, designed to supply through it under the pressure of the washing medium - water and GHS granules 1 - to the user's body - a person / not shown /, as well as a control panel 6 for temperature and pressure of the washing medium . The control panel 6 includes a microprocessor, to the input of which pressure and water temperature sensors are connected, as well as a unit for setting the parameters of the washing medium, which leaves the washing nozzle 5 and the speed of movement of the nozzle 5 in the space of the shower cabin. The microprocessor of the control panel 6, based on the signals received from the temperature and pressure sensors, compares them with the set parameters and issues the corresponding commands to the remotely controlled valves and the drive of the washing nozzle 5 / not shown in the diagram /. The shower unit also includes a storage tank 7, designed to accommodate the GHS 1 with a diameter of D = 5 ... 7 mm, which is connected via a drive / not shown / Archimedean screw 8 to the first input of the mixing tank 9, which is intended for impregnation of the GHS 1 detergent. The second input of the mixing tank 9 is connected to the water supply network / not shown / and provided with valves 10 (for cold and hot water, one is conventionally shown). The valves 10 are installed in series with remotely adjustable valves, which are controlled from the control panel 6. The mixing tank 9 is equipped with a dispenser for supplying liquid detergent and additives to the mixing tank 9 / is not shown in the diagram /. The output of the mixing tank 9 is connected to the input a centrifugal pump 11, the output of which is connected by a flexible pipe 12 to the washing nozzles 5. Each nozzle 5 is mounted with the possibility of its movement and fixing in the washing space bounded by the vertical walls 4. The drain 3 is equipped with a separation device 13 and a device for squeezing SGS 1 and 14 re-feeding them into the mixing tank 9. The separation device 13 is made in the form of a perforated plate, which has the form of a trough, which is inclined mounted under the drain 3. The device 14 for squeezing the GHS 1 is made in the form of a centrifuge, the entrance to which is connected to the lower end of the groove 13 installed under the drain 3, and its output is to the input of the centrifugal pump 15, the output of which through the drive is connected to the storage tank 7. The shower cabin is equipped with a device 16 to protect the user's head - the person - from getting water and GHS 1 on it during washing, which is made in the form of a disk with a central adjustable diaphragm opening designed for its sliding location on the neck of a person during ti and with the possibility of free movement of the user within the boundaries of the space of the shower. For the final rinsing of the body and the supply of clean water without GHS 1 to each washing nozzle 5, the tank 9 is equipped with mesh dampers that do not allow GHS 1 to the tank 9 / not shown /, but only water from the water supply network. The shower cabin is equipped with emergency switches to stop the flow of water and the GHS 1 to the washing nozzle 5. Emergency switches are installed on the base pan 2 and on the vertical walls 4 / not shown /. Each emergency switch is made in the form of a button installed. in a waterproof case on the inner surface of the vertical wall 4 and on the base-base 2. Each button has normally-closed contacts located in series with the electromagnet winding of each remote solenoid valve installed on the main inlet of the water supply network and in the power supply circuits of the drive of the washing nozzle 5, Archimedean screw 8, centrifuge 14 and centrifugal pumps 11 and 15 / not shown /. By pressing the emergency switch, the user completely turns off the electrical power to the electrical devices of the shower cabin, provides automatic drainage of water and the full opening of the diaphragm opening of device 16 - removes the protection of the user's head. The washing nozzle 5 is equipped with a drive designed to move it along a helical line around a vertical axis. The specified drive is equipped with limit switches designed to change the direction of movement of the washing nozzle 5 - up and clockwise, and then down - counterclockwise / not shown /. Moreover, the outlet of the washing nozzle 5 is always directed towards the center of the washing space. To drain waste water into the sewer, the shower cabin is equipped with a drain pipe 17.

The proposed shower works like this.

The user is placed in the shower. To protect the user's head and eyes from ingress of water and GHS 1 during washing, a device 15 is installed on the user's neck. About 2 kg of GHS 1 with a diameter of D = 2.0 ... 4.0 mm are loaded into the storage tank 7. The control panel 6 sets the optimum temperature and pressure of the jet from the washing nozzle 5. From the storage tank 7, with the help of an Archimedes screw 2, the GHS 1 is fed into the mixing tank 9, where the GHS 1 is soaked in water with a liquid detergent - liquid soap. As a result, in the mixing tank 9 are formed GHS 1, impregnated with a washing solution, which consists of water and liquid soap. The SGS 1 impregnated with a washing solution using a centrifugal pump 11 is fed through a flexible pipe 12 to a washing nozzle 5. The nozzle 5 creates a jet of washing solution with SGS 1 directed towards the center of the interior of the shower cubicle, which reproduce the effect of washing with a washcloth on the user's body. The drive of the washing nozzle 5 is turned on. In this case, the nozzle 5 automatically moves along a helical line around the user's body, which ensures automatic washing of the entire body of the user. The spent GHS 1 through the drain 3 is fed to the device 13 for separation along the perforated trough, where they are separated from the water, then to the 14 g centrifuge, where the GHS 1 is squeezed out. After the squeezing process, the GHS 1 is fed by a centrifugal pump 15 to the storage tank 7 for their further use. For the final rinsing of the user's body, the entrances to the container 9 are closed with shutters, and water is supplied to the nozzle 5 from the water supply network. If there is a need for an emergency stop of the shower, the user has the opportunity to press one of the emergency switches and stop the flow of detergent. Thus, the use of the proposed GHS 1 and a shower cabin allows us to solve a number of problems, namely, it provides the ability to wash the user's body automatically and use a variety of additional substances, such as, in particular, relaxers, reducing agents, dermatological preparations, fragrances, stimulants, detergents and other substances at the request of the user. This makes it possible to use the proposed devices both at home and in the conditions of medical and sanatorium institutions, and to use the necessary medical and cosmetic preparations. The proposed devices make it easier to meet the hygienic needs of people with limited functions of the organs of movement. In addition, the use of the proposed devices can significantly reduce the time spent on the body washing process, and can reduce water consumption.
