According to this, outside air smoothly flows into the entering-water pipe 18 which is closed by the closing valves 25a and 25b. Hence, drainage performance is enhanced.
  • Fig. 7 is a sectional view showing a configuration of the air-suction plug 31a in this embodiment.
  • the air-suction plug 31a is fitted into the air-suction passage 32, thereby closing the air-suction passage 32.
  • An O-ring 43 is provided around the tip end of the air-suction plug 31a.
  • the air-suction plug 31a is twisted with a hand and a sealed degree of the air-suction passage 32 by the O-ring 43 is loosened, thereby opening the entering-water pipe 18 into the atmosphere, and outside air is made to flow into the entering-water pipe 18.
  • the entering-water pipe 18 between the outflow port 23b and the closing valve 25b includes the air-suction passage 32 having the air-suction plug 31a. Outside air flows into the entering-water pipe 18 by opening the air-suction plug 31a. Therefore, drainage performance of water which stays between the closing valves 25a and 25b is enhanced.
  • the air-suction device 31 may include an air-suction plug 31a and a negative pressure air-suction valve (vacuum-operated inlet valve) 31b.
  • Fig. 8(a) is a sectional view showing the air-suction device 31 in which the air-suction plug 31a and the negative pressure air-suction valve 31b are integrally provided together
  • Fig. 8(b) is a plan view of essential portions of the check valve body 34 as viewed from communication ports 34a.
  • the negative pressure air-suction valve 31b includes a check valve 33 which receives pressure in the entering-water pipe 18 and atmospheric pressure. If a pressure difference is generated between the pressure in the entering-water pipe 18 and the atmospheric pressure, the check valve 33 accommodated in the negative pressure air-suction valve 31b is operated, and outside air is made to flow into the entering-water pipe 18.
  • the negative pressure air-suction valve 31b includes two check valves 33a and 33b which are arranged in series so that fluid flows in the same direction (toward interior of entering-water pipe 18).
  • the negative pressure air-suction valve 31b also includes a check valve body 34 provided with angular communication ports 34a in which the check valves 33a and 33b are accommodated and which is in communication with the entering-water pipe 18, and an air-suction valve body 35 which is connected to the check valve body 34 and which has an air-suction port 36 for guiding outside air into the check valve body 34.
  • the check valve body 34 and the entering-water pipe 18 are fixed to each other through a bolt 41.
  • the check valve body 34 and the air-suction valve body 35 are fixed to each other through a bolt 42.
  • the plurality of communication ports 34a are provided such that they are deviated from each other in position in the vertical direction and/or the horizontal direction.
  • two communication ports 34a are provided as shown in Fig. 8(b) . According to this, even if one of the communication ports 34a is closed for some reason, outside air can be guided into the entering-water pipe 18 by the other communication port 34a.
  • the air-suction valve body 35 has a plug hole 35a into which the air-suction plug 31a is fitted.
  • the air-suction port 36 is closed by fitting the air-suction plug 31a into the plug hole 35a.
  • the air-suction plug 31a can open the air-suction port 36.
  • a hose 38 is connected to the air-suction port 36.
  • Fig. 8 shows a state where the air-suction port 36 is opened by the air-suction plug 31a.
  • a stopper 39 which can be attached to and detached from the air-suction plug 31a maintains a state where the air-suction port 36 is opened by the air-suction plug 31a.
  • the entering-water pipe 18 is closed by the closing valves 25a and 25b and then, the air-suction port 36 is opened by the air-suction plug 31a.
  • the drainage passage 26b is opened by the drainage valve 26a.
  • the flow path is first closed by the closing valves 25a and 25b.
  • the drainage valve 26a of the drainage passage 26b is opened, and water which stays between the closing valves 25a and 25b is drained.
  • the entering-water pipe 18 may be opened into the atmosphere by the air-suction device 31, and outside air may be made to flow into the entering-water pipe 18.
  • the water quality adjusting portion 23 which can be attached to and detached from the entering-water pipe 18 is removed. According to this, only water which stays between the closing valves 25a and 25b is drained, and it is unnecessary to drain water in the entire water heater. Hence, maintenance of the water quality adjusting portion 23 can efficiently be carried out.
  • Fig. 9 is a schematic block diagram of a water heater according to a fourth embodiment of the invention
  • Fig. 10 is a schematic block diagram of a water quality adjusting unit of the water heater.
  • the same symbols as those of the first to third embodiments are allocated to the same members, and detailed description thereof will be omitted.
  • the air-suction device 31 is placed downstream of a branching location between the main flow path 18a and the auxiliary flow path 18b with respect to a flowing direction of water which flows through the entering-water pipe 18 and upstream of the connecting portion 47b.
  • a connected location between the air-suction passage 32 and the entering-water pipe 18 is higher in the vertical direction than the water quality adjusting portion 23.
  • the connected location between the air-suction passage 32 and the entering-water pipe 18 may be located on any of the main flow path 18a and the auxiliary flow path 18b.
  • the air-suction device 31 may have the air-suction plug 31a as shown in Fig. 7 or may have the air-suction plug 31a and the negative pressure air-suction valve 31b as shown in Fig. 8 .
  • the water heater of the present invention suppresses deposition of scale by the water quality adjusting portion, and maintenance easiness of the water quality adjusting portion is enhanced. Therefore, the invention can be applied to domestic and professional-use water heaters.
