Definitions

  • This invention relates to a shower device provided with a water heater, more particularly to a shower device wherein hot water heated in an instant type or a storage type water heater is admixed with a desired quantity of cold water so as to sprinkle water of the desired temperature through a shower head.
  • water from a source is caused to flow through two branches b and b, one of them b extending through an instant waterheater a.
  • the hot water from the water heater a and cold water through branch b are mixed together at a desired proportion by means of hot watercold water mixing cocks c and c in branches b and b to supply the mixture to a shower head d via a conduit e.
  • Cocks c and c maybe interlocked with each other so as to operate simultaneously.
  • the shower head manifests a large resistance against the flow of the hot water and as the quantity of water is increased the internal pressure in the shower head becomes higher. This increased internal pressure increases the back pressure for the water heater a thus decreasing the flow quantity therethrough and increasing the temperature therein. Actually, however, it is desirable to mix more quantity of cold water, but admixture of such larger quantity of cold water results in further decrease in the quantity of hot water. In an extreme case, the water in the water heater boils, or its heating circuit is deenergized. Such a problem has been considered inevitable in the instant type water heater and no satisfactory solution has not yet been proposed in the past.
  • cold water from a supply not shown is supplied to a sister tank B through a float valve G contained in the sister tank B, as shown in FIG. 3.
  • the cold water in the sister tank B is supplied to a storage tank A via a conduit E and the water heated in in the storage tank A is supplied to shower head d through a cock c.
  • the cold water which is in the sister tank B is directly supplied to the shower head through a conduit F including cock c.
  • sister tank B is located at a level about 2 to 3 meters higher than the level of the shower head the pressure of the hot water supplied to the shower head is less than 0.1 to 0.2 Kg/cm. which is not sufficient to provide efficient shower stream.
  • a shower device wherein a mixture of hot water from a hot water heater and cold water from a source of supply is supplied to a shower head through cocks, characterized in that the shower head is provided with at least one hot water discharge port and at least one cold water discharge port, that the hot water from the water heater is supplied to the hot water discharge port through a hot water conduit including a cock and that the cold water is supplied to the cold water discharge port through a cold water conduit also including a cock whereby the hot water and cold water are admixed near the hot water and cold water discharge ports of the shower head.
  • FIG. 1 is a schematic representation of a prior art shower device utilizing an instant type water heater
  • FIG. 2A and 2B show graphs representing the relationship between the flow quantities of cold water and hot water, and the extent of opening of the hot water-cold water mixing cocks, especially when they are interlocked;
  • FIG. 3 is a schematic representation of a prior art shower device utilizing a storage type water heater
  • FIG. 4 shows a partial view, partly in section, of one exam ple of the novel shower device utilizing an instant type water heater
  • FIGS. 5 and 6 show partial sectional views of modified shower heads
  • FIG. 7 shows a graph representing the relationship between the flow quantities of cold water and hot water, and the extent of opening of the hot water-cold water mixing cocks of the embodiment shown in FIG. 4, and
  • FIG. 8 is a diagrammatic representation of another embodiment of this invention utilizing a storage type water heater.
  • the I hot water from an instant type water heater is supplied to a hot water conduit 2 including a cock 3 while cold water is supplied to a cold water conduit 1 including a cock 3'.
  • Cocks 3 and 3' may be operated independently or simultaneously by means of a suitable interlocking mechanism, not shown.
  • Outlet sides of cocks 3 and 3' are connected to a shower head 6 through conduit 4 and 5 respectively.
  • the head 6 is provided with a plurality of hot water discharge ports 7 and a plurality of cold water discharge ports 8 each concentric with one of the hot water discharge ports 7 to admix cold water and hot water immediately below these discharge ports.
  • hot water conduit 4 is concentrically disposed in the cold water conduit this constituting a double walled pipe. Hot water is supplied from hot water conduit 4 to the inner chamber 10 of the shower head 6 and the cold water from the cold water conduit 5 is supplied to the outer chamber 1 1. With this construction, the temperature of the outer casing 9 of the head 6 does not rise to a dangerous value.
  • hot water discharge ports 7 take the form of short pipes at the bottom 10 of the inner chamber 10 and extending through cold water discharge ports 8 provided in the bottom wall 9' the outer casing.
  • the hot water discharge pipe 7 terminates a short distance above the cold water discharge port 8, in which case the cold water and hot water are admixed in the shower head, or in a space between the lower end of pipe 7 and the upper end of the discharge port 8.
  • a pointed wedge shaped barrier 13 is partially inserted into a discharge opening 12 of the shower head 6 to supply the hot water from the hot water conduit 4 to the left of the barrier 13 and the cold water from the cold water conduit to the right.
  • the hot and cold water are mixed together in the discharge opening 12. It is to be understood that other constructions may be used to admix the hot and cold water.
  • FIG. 8 shows a modified embodiment of this invention utilizing a storage type water heater comprising a water heating tank 15 having a float valve 16 and a hot water tank 14 which are arranged similar to FIG. 3.
  • the quantity of the cold water discharged from cold water discharge ports 8 can be varied so that shower water of desired temperature can be instantly available.
  • a mixture of hot water from a water heater and cold water from a source of supply is supplied to a shower head through cocks, which comprises at least one hot water discharge port and at least one cold water discharge port provided for the shower head, a hot water conduit extending between said water heater and said hot water discharge port, a cock in said hot water conduit, a cold water conduit extending between said source and said cold water discharge port, and a second cock in said cold water conduit, the improvement therein wherein said hot water conduit passes within said cold water conduit and, each of said hot water discharge ports is concentric with each one of said cold water discharge ports, said hot and cold water mixing only at said discharge ports.
  • shower head comprises an inner chamber provided with a plurality of hot water discharge ports at its bottom and connected with said hot water conduit and an outer chamber provided with a plurality of cold water discharge ports at its bottom and connected with said cold water conduit.
