Description

FIELD OF THE INVENTION

The invention relates to pipe fittings, in particular to mixing devices designed for mixing in different proportions of hot and cold water and supplying it to a shower or pouring into a bath and is presented as a group of two proposed inventions of the same purpose.

State of the art

A device is known (see the prospectus of the German company Jdeal Standard from Bonn: magazine "Das Bad-Jdeal. Die Armaturen-Collectionen von Jdeal Standard" No. W 603A p. 49, brand A2800 mixer), containing a housing with channels for supplying hot and cold water and drainage of mixed water for shower or spout, two identical valve heads with rotary eccentric handles and distributive movable and fixed plates, each movable plate kinematically connected to the handle, a unit for switching mixed water to shower or spout located in the housing between the valve heads holes, and in all the plates there are made through windows with jumpers between them, and these windows are aligned with each other in the “OPEN” position and are placed under the jumpers in the “CLOSED” position.

The disadvantage of this device is the design complexity due to the presence of a separate unit for switching mixed water to shower or spout, as well as the inconvenience of use is that, for example, to increase the pressure of the water while maintaining its temperature, it is necessary to use both handles; the same, if you need to change the temperature of the water, and leave its pressure unchanged, in addition, you must use the third control - the "shower spout" button.

A device is also known (see USSR author's certificate No. 1536134 of 03.24.1987), comprising a housing with channels for supplying hot and cold water and for discharging mixed water to the shower and spout, a cover, movable and fixed distribution plates, and in a fixed plate input and output windows connected to the channels of the housing are made, the movable plate through the control unit is kinematically connected to the drive handle, and the windows for draining water to the shower and spout are from different sides from the supply windows, and on the surface of the movable plate Nena two recesses separated by a bridge arranged to communicate with one of the input windows and output simultaneously overlap bridge two input window at the position "CLOSED" actuator arm defined by a ball retainer mounted on the adjustment unit.

The disadvantage of this device is the inconvenience in use due to the fact that since the cover 6 and the movable plate 8 have radial grooves in which the pin 20 and the protrusion 23 respectively move, as a result of the decomposition of the forces in these grooves when turning the handle, additional friction against the walls these grooves, which increases the handle rotation force and, since the mixer has been used for decades, leads to wear of rubbing parts, i.e. to the appearance of play in the connection, which is also inconvenient to use and reduces the service life.

Since the recesses in the movable plate have a different cross section, then after switching the water flow to the desired temperature, for example, from the spout to the shower, the temperature of the water flowing out of the shower will change, which is also an inconvenience to use, because re-adjustment of the desired water temperature is required.

In addition, to set the handle of the mixer in the "CLOSED" position, it is provided for vertical fixation with a ball retainer.

Disclosure of invention

The technical result of the present invention (for the first of the claimed group) is to create a mixer that is simple in design and use by eliminating the separately configured "shower-spout" switch and increasing usability by reducing controls and separating the functions of controls that are independent of each other adjustment: one knob - mixing water to the desired temperature or supplying only hot or only cold water without changing the flow, the second knob - changing only water flow with a simultaneous direction of it to a shower or spout.

The technical effect is achieved by the fact that in the mixer in all the design and construction options of its casing, it is new that it is equipped with an additional casing channel, one of which connects the output central through window in the fixed distribution plate of the first valve head with the input window in the center of the fixed distribution plate the second valve head, whose arcuate through windows, located around the central window, are each connected to additional channels of the housing connecting them to the ear and spout, respectively, and the rotation of the movable distribution plate of the same valve head ensures the supply of mixed water with the regulation of its flow to the shower or spout.

The technical result of the invention (for the second of the claimed group) is to create a convenient mixer in use by maintaining the temperature and pressure of the mixed water when switching from shower to spout and vice versa, increasing the service life by eliminating from the design wear parts that cross movement relative to each other friend, and also due to the convenient installation of the handle in its neutral position in the state of the mixer "CLOSED".

The technical effect is achieved by the fact that the mixer is new in that it is equipped with additional crossing channels, one of which is located in the upper part of the fixed distribution plate and connects to each other two additional through windows located diametrically opposite to its center and equidistant from those in windows, and the other channel is made in the case and at its opposite ends are made windows that are conjugated by a joint window with three of four through windows in a fixed distribution plate, and on the inner spherical surface covering the top of its handle body, intersecting grooves are made, one of which is horizontal and the other vertically, and at the intersection they are made with a greater depth than these grooves, the recess in which the ball retainer is installed in the upper part of the housing.

The proposed first mixer (of the two declared), in each of twenty options for the design of its housing (Figs. 1 to 20 and from 22 to 54) contains a housing 1 with channels 2 and 3 for supplying hot and cold water and channels, respectively 4 and 5 drain mixed water for shower and spout, respectively. The mixer has two identical valve heads 6 and 7 with rotary knobs 8 and 9. Each valve head (Fig. 55) contains a sleeve 10 with a protrusion made in the form of a pin 11, which, depending on the location of the head in the housing of different versions of the mixers, can be installed in diametrically opposite hole in the sleeve 10. Fixed distribution plate 12 with a sealing gasket 13, curved windows 14 and 15 and a round window 16, separated by jumpers 17 and 18. The movable distribution plate 19 has one window 20 and it is mathematically connected with the handle through the roller 21 by means of the protrusions 22 of this roller entering the recesses at the end of the movable plate. Between the movable plate 19 and the roller 21 is installed a sealing gasket 23.

In the embodiment of the valve head (Fig. 59), the through window 20 is converted into a recess, which reduces the longitudinal size of the head and eliminates the gasket 23.

In the mixer embodiments shown in FIG. 22 to 50, the first embodiment of the valve head is applied (FIG. 55), in the mixer version of FIG. 51, the second embodiment of the valve head (FIG. 59).

The channel 2 for supplying hot water to the housing is connected to one of the arched windows of the fixed plate 12 of the head 6, and the channel for supplying cold water 3 to another arcuate window (for example, with windows 14 and 15, respectively). The round windows 16 in the heads 6 and 7 are connected to each other by a channel 24 of the housing, and the channels for discharging mixed water 4 for a shower and 5 for a spout are conjugated with arcuate windows 14 and 15 of the fixed plate 12 of the head 7 (Figs. 23 through 28).

Each of the twenty proposed mixer versions has similar channel connections (Figs. 1 to 20), which is confirmed by a selective representation of the device drawings for seven of the presented variants (Figs. 22 to 28, 29 to 33, 34 to 35, s 36 to 40, 41 to 45, 46 to 50, 51 to 54). The internal device of the remaining thirteen options is not conditionally shown as identical to the ones shown.

The implementation of complex internal channels in the housing is ensured by fixing in the mold additional rods of special fusible material with their subsequent smelting from the finished casting.

It is also possible to design the housing from separate parts with subsequent connection to each other by welding, soldering in combination with mechanical fastening (not shown in the drawings).

At the same time, the same design of the outlet channels of the spout and shower in versions 2 ... 5, 8 and 11 of the mixer provides the possibility for the consumer to swap the spout and shower tubes between themselves, depending on the convenience of using them.

All versions of the mixers are shown in the drawings in the "CLOSED" position.

The proposed mixer (in any embodiment of its housing and execution of its valve head) works as follows.

In the “CLOSED” position shown in the drawings, the cold and hot water supplied to the channels 3 and 2 of the housing 1, respectively, is blocked by the movable plate 19 of the head 6, since its window or recess 20 is rotated 180 ° relative to the inlet windows 14 and 15 of the fixed plate 12. The rubber gasket 13 provides mechanical seal between the housing 1 and the plate 12. The seal between the ceramic plates 12 and 19 is ensured by grinding the surfaces in contact with each other. To supply, for example, cold water to the spout, it is necessary to turn the handle 8 around its axis until the window 20 in the movable plate 19 is aligned with the window 15 in the fixed plate 12 by an angle slightly more than 90 ° with the orientation of the oval protrusion of the handle 8 in options 1 ... 14, 16 ... 20 or the trapezoidal protrusion of the handle 8 in option 15 in the direction of the blue mark on the housing 1 (Fig.41). The valve head 6 is open to cold water, which enters through the window 16 into the channel of the housing 24 and reaches the valve head 7, which at this moment is still closed. To supply water to the spout with the required water flow rate, the handle 9 of the mixer must be turned in the necessary direction towards the marking on the handle itself (not shown in the drawings), while the head of the water outflow increases with an increase in the angle of rotation.

To supply cold water to the shower, turn the handle 9 in the opposite direction. When this water from the channel of the housing 24 passes through the window 16 of the valve head 7 and the corresponding arched window in it, falling on the channel of the shower 4 or spout 5.

To supply hot water to a shower or spout, it is necessary to turn the handle 8 of the mixer (from the “CLOSED” position) in the direction of the red mark on the body 1 to the same angle of rotation, then use the handle 9.

Since the valve heads 6 and 7 operate independently of each other, you can first use the handle 9 to set the direction of the flow of water (spout or shower), and then use the handle 8 to turn on either cold or hot water, if the handle 9 is rotated through an angle of 90 ° and a little more, then turning the knob 8 produces a smooth increase in the pressure of hot or cold water, i.e. in the mode of supplying only cold or only hot water to a shower or spout, the water flow can be adjusted either with handle 9 (with the channel in head 6 fully open) or with handle 8 (with the channel fully open in head 7).

To give warm (mixed) water to a shower or spout, it is necessary (best) with handle 9 closed to turn handle 8 from the “CLOSED” position in any direction by 180 °, while the window or recess 20 in the head 6 equally covers both windows 14 and 15 in the fixed plate 12, and mixed water is supplied to the head 7. The handle 9 then ensures that the shower or spout is turned on and the desired water temperature is adjusted by turning the handle 8 left and right.

The adjustment of the water flow in this case is carried out only by the handle 9.

The position “CLOSED” in any of the options is made by turning the handles 8 and 9 in any sequence to the position where the contours of the handles coincide with the contours of the housing, which is very convenient during operation, as the mixer is immediately open or closed - this is especially important when the water in the water supply system is temporarily turned off.

The advantages of the claimed mixer (the first of the two claimed) include: simplification of the design by eliminating a separate water switch "shower-spout" and it is more convenient to use, since the adjustment of water mixing is carried out regardless of the adjustment of its flow rate, and vice versa, as well as due to reducing the number of controls, in addition (as can be seen from the twenty options presented), opens up a wide field of activity for new design solutions.

The proposed second version of the mixer (Fig.21 and 62 ... 71) of the two claimed contains a housing 31 with channels 32 and 33 for supplying hot and cold water, respectively, and channels 34 and 35 for diverting mixed water to the shower and spout, respectively. The housing 31 is provided with a cover 36. Inside the housing, a locking unit is installed in the form of a fixed 37 and a movable 38 distribution plate made of ceramic material. In the fixed plate 37, through holes 39 and 40 for supplying hot water, connected to each other by a groove 41, and through holes 42, 43 for supplying cold water are arranged symmetrically with respect to the center, and through windows 44, 45 for draining are made from different sides of them water to the shower or spout, respectively, combined with the corresponding windows of the channels of the body. The window 40 is a technological one and serves for symmetrical execution of the fixed plate 37. Between the body and the fixed plate 37 there is installed the only sealing gasket 46 in the mixer. On the bottom side of the fixed plate 38 there are two recesses 48 and 49 separated by a jumper 47, placed with the possibility of communication of the windows 40, 43 with the output window 44 and the input windows 39, 42 with the output window 45 and the simultaneous overlap of all input windows with the position of the handle 50 of the drive "CLOSED". The actuator of the handle 50 is equipped with a control unit and the position of the movable plate 38 and consists of a lever 51 having a square section in the upper part onto which the handle 50 is mounted, and below a rectangular section of variable length (Fig. 64), and fixed to rotate in vertical plane in the center of the cover 36. The lower end of the lever 51 in the plane of its rotation is pivotally connected to the washer 52, to the lower plane of which a movable plate 38 is attached.

A washer 53 is mounted on top of the cover 36, rigidly connected to the body (Fig. 64) with a stop 54 mounted therein, made in the form of a pin, restricting the horizontal rotation of the cover 36 and the handle 50 by placing its lower end in its arcuate groove. The rotation of the handle 50 up and down is limited by the tilts of the lever 51 in the cover 36 by the configuration of the hole in which it is installed.

The housing 31 in the channel 33 for supplying cold water is provided with an additional channel 55 with two outlet openings 56 and 57, and this channel is located across the channel (grooves) 41 in the fixed plate 37 so that the window 32 of the housing is interfaced with the window 39, and the windows 56, 57 - with windows 43, 42, respectively, in a fixed plate.

On the inner spherical surface of the handle 50, intersecting grooves 58 and 59 are made, located horizontally and vertically, respectively, and a recess is made at the point of their intersection with a depth greater than these grooves, in which a spring-loaded ball 60 of a retainer installed in the upper part of the housing 31 is located.

The mixer (option 21) works as follows.

In the “CLOSED” position, the handle 50, the lever 51, the washer 52, the movable 38 and the stationary 37 of the plate are placed in such a way that their central axes coincide. In this case, the windows 39, 40, 42, 43 and the groove 41 for supplying hot and cold water on the fixed plate 37 are blocked by a jumper 47 of the movable plate 38, and the windows 44, 45 of the water drain for shower and spout are partially aligned with the recesses 48, 49, respectively, on the movable plate 38.

The position of the movable plate 38 is determined by the location of the handle 50 in the horizontal plane with the fixing of the spring ball 60 in the recess at the intersection of the grooves 58 and 59.

Also, the mixer will be in the "CLOSED" state at any angular position of the handle 50 in the horizontal plane (the ball 60 will be located in the horizontal groove 58), since the jumper 47 has a larger diameter than the outer diameter of the recesses in the fixed plate 37, in which water supply windows 39, 40, 42, 43, and therefore closes them.

To supply warm (mixed) water, for example, to the spout in the bath from the position of the mixer shown in Fig. 62, it is necessary to turn its handle 50 down, while the ball 60 will exit the recess in the crosshairs of the grooves 58 and 59 and will move along the groove 59 At the same time, the lever 51 is bent on the axis of its rotation, with its lower end it moves to the left (Fig. 64) the washer 52 with the movable plate 38, which with its recess 49 will open the recesses in the stationary plate 37, in which the windows 39 and 42 for supplying hot and cold water accordingly, connecting them with you odnymi windows 45 and further to the channel 35 of the spout into the bath. In this case, cold water enters from the channel 33 through an additional channel 55 and its hole 57 into the window 42, while the window 56 (Fig. 72) is blocked by a jumper 47 of the movable plate.

To supply hot (cold) water, the handle 50 must be moved from the downward position to the side of the hot (cold) water supply to the mixer (according to the color marks on the body or handle), while the ball 60 will exit the groove 59 and will roll along the inner sphere of the handle 50. At the same time, the lever 51 will rotate (counter-clockwise) (when viewed from above) through the washer 52 of the movable plate 38, which with its recess 49 will provide a larger (smaller) overlap of the hot water supply window 39 and a smaller (larger) overlap of the supply window 42 cold water, which ensures a change in the temperature of the water being poured out, and an increase (decrease) in the downward inclination of the handle increases (decreases) the flow (pressure) of the outflowing water due to the simultaneous overlapping of the larger area of windows 39 and 42 with the recess 49.

To change the direction of the flow of mixed water from the spout into the bathtub to the shower, and without changing its temperature or only cold, or only hot, it is necessary to move the handle 50 from any horizontal position horizontally above the horizontal position, while passing the horizontal position of the handle 50 the outflow of water from the spout 35 will stop: the jumper 47 of the movable plate 38 will be located above the windows 39, 40, 42, 43, that is, it will close them, and then with its recess 48, leaving the windows 44 open (they are connected to the channel 34 to the shower), open t and thereby connect windows 43 and 40 to them, while hot water enters recess 48 through channel 32, window 39 and groove 41, and cold water through channel 33, additional channel 55, hole 56 in the housing and window 43 in the fixed plate: the water temperature from the shower has not changed, since the plates 37 and 38 are made with windows and recesses symmetrically located in them, and the movement of the plates relative to each other occurred through the center of the fixed plate in a diametrically opposite direction.

By analogy with the above, only cold or only hot water is supplied both to the shower and the spout, as well as their subsequent mixing to the required temperature.

When smoothly moving in any direction of the handle 50, the movable plate 38 moves smoothly along the fixed plate 37, which, in turn, provides a smooth change in their passage sections of the hot and cold water supply windows and, therefore, stepless regulation of the water flow from minimum to maximum as well as its temperature.

Turns of the handle 50 can be made in any sequence: right - left, up - down, as well as simultaneous movement, for example: down and left, up and right, etc., therefore, to move the handle 50 to the "CLOSED" position, you can turn it in any desired direction, for example: down - up until the ball 60 enters the groove 58, and then to the right - to the left until this ball enters the recess at the intersection of the grooves 58 and 59 with each other.

The advantages of the claimed mixer (the second of the two declared) include the improvement of its operating conditions by increasing ease of use, as:

1. The temperature of mixed water remains constant when it is switched from a spout to a shower and vice versa.

2. The possibility of the appearance of backlash in the handle during long-term operation of the mixer due to the exclusion from its design of components with increased friction, and, as a result, a decrease in the rotation force of the handle and an increase in the service life, is excluded.

3. It is easier to move the control handle of the mixer to the “CLOSED” position due to the use of two grooves intersecting at right angles on its inner spherical surface with a large recess at their intersection, into which the fixation ball is installed, and the flow of only cold (hot) water is facilitated , since the handle 50 is strictly horizontally moved to the right - to the left by rolling the ball 60 along groove 58 and only then up and down (with the ball coming out of the groove) for direct water supply to the shower or spout.
