Description

 The invention relates to devices for physiotherapy, namely to shower units for thermal contrast hardening.

 Known shower installation, containing pipelines for supplying cold and hot water, a mixer with inlet pipes and valves, a flow switch and a shower nozzle. The shower unit of this design allows you to alternately flow from the shower head flows of cold and hot water.

 This installation has several disadvantages. It is not possible to control the temperature of one of the flows, since there is only one mixer in the installation. It is difficult to accurately control the temperature of the water passing through the mixer. The reason for this is that the flow switch is a rotor rotating in the housing, periodically partially overlapping the through holes for cold or hot water. Since the rotor rotates when water is supplied, the outlet temperature constantly changes, which makes it difficult to control. The known installation has low reliability due to the fact that the rotor, rotating under the action of only the dynamic component of the water pressure, develops an insignificant moment of forces and its rotation speed can change until it stops completely due to contamination or the appearance of rust on the bearings. Another disadvantage of the shower unit is that it does not provide a contrast of water temperatures when switching due to leaks when the channels are blocked by rotor elements.

 The closest to the proposed technical essence and the achieved positive effect is a contrast shower, containing pipelines for supplying cold and hot water, two mixers, a spool flow switch and a shower head. Shower installation allows you to receive a stream with a periodically changing temperature. Although this contrast shower has greater reliability and its design allows precise temperature control of cold and hot water flows, it also has drawbacks. This shower cannot be used as a regular faucet-mixer in bathrooms, since it has no spout and does not provide hot or cold water, which limits its scope. At the same time, this shower does not provide a high contrast of the temperature of the flows necessary to achieve a high hardening effect. The reason for this is that cold and hot water alternately enter the cylindrical cavity between the spool-flow switches. There, mixing of streams having different temperatures occurs, with the formation of a portion of water having a certain average temperature value. After blocking one of the holes in the cylinder with a slide valve, stopping the supply of water with one temperature from it, opening another hole and supplying water with a different temperature from it, water with an intermediate temperature enters the shower head for some time.

 The aim of the invention is to expand the scope and increase the contrast when switching.

 The goals are achieved by the fact that the well-known thermal contrast shower containing pipelines and valves for supplying cold and hot water, mixers, a first flow switch with a switching element and a shower head, is equipped with a second flow switch, a spout, a pipe connecting the first and second flow switch, the switching element is made in the form of a conical tube with a L-shaped and isolated radial channels.

 The presence in the inventive device of a second flow switch, a spout pipe and a pipe connecting the first and second switches allows the device to operate in standard faucet-mixer modes with a shower and a spout for bathrooms and a high-contrast shower. In the mixer tap mode, using the second water flow switch, the water supplied from the mixer can be directed either to the spout or to the first flow switch, and from it to the shower head. If it is necessary to operate the device as a contrast shower, water is supplied simultaneously from both mixers to the first flow switch. Periodic switching of the first switch provides the supply of water flows with different temperatures to the shower head.

 The operation of the device in the mode of a standard mixer tap may precede its operation as a contrast shower. In this case, due to the alternate start-up for a time sufficient to select the temperatures of the cold and hot flows, the temperature regime of the contrast shower can be precisely selected.

 The implementation of the first flow switch with a switching element in the form of a conical plug containing a L-shaped channel and an isolated through radial channel, provides high temperature contrast during switching. High contrast of the flows entering the shower nozzles is achieved by the fact that when switching flows using a plug containing mixed channels for mixing flows within the switch, there is no mixture of different temperature flows with an intermediate temperature. It also excludes mixture formation that the opening of one of the channels, for given angular dimensions of the cork elements and supply channels in the switch housing, occurs only after closing the other channel.

 The operation of the claimed device in the mode of a contrast shower is carried out as follows in two stages.

 At the first stage, the water flow is adjusted and the contrast flows are adjusted to the required temperatures. For this purpose, valves 10 and 11 are opened and regulated, respectively, on cold and hot branches. Through the mixer 1, water is supplied to the first flow switch 3, the control handle of which is installed to receive water from the first mixer 1. From the flow switch 3, water enters the shower head 6 through line 12. Water enters the shower head for the time required for precise control her temperature. The control can be carried out by a thermometer 19 installed on the pipeline 12 in front of the shower head 6, or, for example, by human skin receptors. After adjusting and selecting the temperature of the first of the contrasting streams, the flow rate is selected and the temperature of the second stream is set.

 At the same time, valves 8 and 9 are opened and regulated on cold and hot branches. The water flow through the second mixer 2 enters the second flow switch 4, the control handle of which is installed to supply water to the pipeline 7. After installing the control handle of the first flow switch 3 to receive water from the pipeline 7, the second of the contrasting streams enters the shower head 6 through the pipeline 12 and is controlled by a thermometer 19 or, for example, human skin receptors.

 At the second stage, a treatment and prophylactic procedure is performed.

 By turning the plug 16 of the first flow switch 3 manually or automatically periodically to the outlet 13, a fixed-temperature water stream is supplied from the first mixer 1 through the L-shaped channel 14 or a second water stream with a fixed contrast temperature is supplied from the second mixer 2 through a radial isolated channel 15 of outlet 13, flows flow through the pipeline 12 to the shower nozzle 6 in turn. Due to the fact that hot and cold water move in the first flow switch 3 through different channels, a water flow is provided b of stirring, the stable temperature value for each period that provides high contrast flow and positive effect of the procedure.

 The operation of the claimed device in the mode of a standard faucet-mixer for bathrooms is as follows.

 Valves 8 and 9 open and water through the second mixer 2 enters the second flow switch 4. From the flow switch 4, with the appropriate installation of the control handle, water can be supplied to the spout 5 or through the first flow switch 3, which is connected to receive water from the pipeline 7, shower head 6.

 If necessary, the inventive device can perform a new function that is missing from the mixer tap for bathrooms.

 The simultaneous supply of water with one specific temperature to the shower head 6 and with another specific temperature to the spout nozzle 5 can be carried out. By opening and adjusting the valves 10 and 11 with the first flow switch 3 turned on, the desired temperature of the water leaving the first mixer 1 is selected shower head 6.

 By opening and adjusting valves 8 and 9 with the second flow switch 4 turned on, water is dispensed from the second mixer 2 to the spout 5 and the desired water temperature of the second stream is selected.
