Definitions
- a mixer tap A mixer tap .
- the present invention relates to a mixer tap for mixing two flowing media, e.g. hot water/cold water or water/steam, of the kind as stated in the preamble of the following inde ⁇ pendent claim 1.
- two flowing media e.g. hot water/cold water or water/steam
- mixer taps A large number of different mixer taps is known and used for mixing, e.g. hot and cold water or water and steam and for mixing a plurality of other media in chemical industry and food processing industry. It is an object of the present invention to provide such a mixer tap, which is very simple and sturdy and shows good mixing capability as well as being inexpensive in production.
- the mixer tap is suitable for mixing cold water and hot water, and it is especially suitable for mixing cold water with steam so as to achieve a desired temperature of the discharged medium.
- the mixer tap according to the invention will be disclosed in more detail below with reference to an embodiment of the mixer tap shown in the drawing.
- Figures 1 and 2 show a known mixer tap with fastening brackets, as seen in cross section from one side, and in a top view;
- Figure 3 is a perspective view of the known deflector means of the mixer tap in the shape of an arched guide board
- Figure 4 is a sectional view of the mixer tap according to the invention as seen from one side and with a deflector means in the shape of a pipe with exhaust ports;
- FIG. 5 is a top view of the mixer tap with steam injector pipe shown in dashed lines.
- Figures 6a, 6b show the steam injector pipe in an elevational view, and from below, respec ⁇ tively, relative to the orientation of the mixer tap in the above mentioned Figures.
- Figures 1 and 2 show a known mixer tap which comprises an elongated housing 1 in the shape of a parallelepiped and with a width B which in the shown embodiment approximately corresponds to twice the depth D of housing 1.
- Housing 1 is provided with fastening brackets la, lb at its ends for mounting on a support.
- housing 1 In one of its elongated sides housing 1 is provided with two inlets 2, 3, one at each end portion of the housing, and an outlet 4 is provided opposite to one inlet 2 on the facing side of housing 1.
- the inlets and outlets are shown in the shape of connecting sleeves which are arranged normal to the longitudinal direction of housing 1 in its longitudinal sides.
- a deflector means 5 is provided inside housing 1 and is placed between inlet 2 and outlet 4 opposite to inlet 2 in order to deflect the direction of the medium flowing into inlet 2 into the longitudinal direction of housing 1, towards the other inlet 3 for admixture with medium flowing in from inlet 3 in a counterflow. The resulting mixed medium is then discharged through outlet 4.
- the deflector means 5 in the known embodiment of the mixer tap shown in Figures 1 and 2 consists of a guide board 6 extending across housing 1 from one wall to the other, and forming an arch 6a from one side 2a of inlet 2 down towards the longitudinal axis A of housing 1.
- the arch 6a of the guide board is here transformed into a straight portion 6b ending at a distance from the central portion of the housing.
- said straight portion forms an acute angle with the longitudinal axis A of the housing and is inclined away from inlet 2.
- Figure 3 shows the guide board of Figure 1 in a perspective view.
- FIG 4 shows the mixer tap according to the invention, the mixing means of which consists of a pipe 7 - a steam injector pipe - with a closed end 7c.
- Pipe 7 is arched 7a from inlet 2 in the direction of the second inlet 3, and it is provided with a number of ejector ports 7d.
- arch 7a of pipe 7 is transformed into a straight pipe portion 7b, which extends in the longitudinal direction of housing 1, and in which ejector ports 7d are provided.
- Pipe portion 7b is parallel with the longitudinal axis A of housing 1 and is in the shown embodiment arranged in the longitudinal half of housing 1 which is closest to inlets 2 and 3.
- Ejector ports 7d are arranged in a row 8 along pipe portion 7b on the side of the latter facing the other longitudinal half of housing 1 with outlet 4. As shown in Figure 6, pipe portion 7b is provided with a central row 8 of ejector ports 7d as well as adjacent rows 8' of ejector ports 7d. The central row 8 is longer than both adjacent rows 8'.
- the mixing tap is mounted on a wall or another support by the aid of fastening brackets la, lb and is connected with supply pipes for media at connecting sleeves in inlets 2 and 3 as well as with a discharge pipe at outlet 4.
- taps may be provided in a manner known per se for opening and closing supply of media. Said taps may be interlocked, e.g. to prevent unintentional opening of steam supply without simultaneous supply of water to the mixer tap. As known per se, this will prevent injuries due to scalding by ejected steam from outlet 4 or a pipe which is connected with the latter.
