  • the water inlet-side cover member 610 may have the shape of a cylinder whose upper portion is open.
  • the shape of the water inlet-side cover member 610 is not particularly limited, and any shape may be used as long as the water inlet-side cover member 610 may cover the portion of the heating part 400.
  • a first exposure hole 611 may be formed in the water inlet-side cover member 610, for example, in a lower surface of the water inlet-side cover member 610. Accordingly, the water inlet nipple 220 of the water inlet part 200 may pass through the first exposure hole 611 to be exposed to the outside. This may allow the discharge member such as the cock or the faucet to be readily connected to the water inlet nipple 220.
  • a coupling groove 612 may be formed on the water inlet-side cover member 610, for example, on the inside of the open upper portion of the water inlet-side cover member 610.
  • the coupling groove 612 may have an 'L' shape, as illustrated in FIG. 2 .
  • the shape of the coupling groove 612 is not particularly limited, and any well-known shape may be used as long as the coupling protrusion 622 of the water outlet-side cover member 620 may be inserted in the coupling groove 612, such that the water outlet-side cover member 620 may be coupled to the water inlet-side cover member 610.
  • the water outlet-side cover member 620 may be coupled to the water inlet-side cover member 610. In addition, the water outlet-side cover member 620 may cover the remainder of the heating part 400 and the water outlet part 500.
  • the water outlet-side cover member 620 may have the shape of a cylinder whose lower portion is open.
  • the shape of the water outlet-side cover member 620 is not particularly limited, and any shape may be used as long as the water outlet-side cover member 620 may cover the remainder of the heating part 400 and the water outlet part 500.
  • a second exposure hole 621 may be formed in the water outlet-side cover member 620, for example, in an upper surface of the water outlet-side cover member 620. Accordingly, the water outlet nipple 520 of the water outlet part 500 may pass through the second exposure hole 621, to be exposed to the outside. This may allow the water outlet nipple 520 to be easily connected to the water supply.
  • the coupling protrusion 622 may be formed on the outside of the open lower portion of the water outlet-side cover member 620, for example.
  • the lower portion of the water outlet-side cover member 620 may be inserted in the upper portion of the water inlet-side cover member 610.
  • the coupling protrusion 622 of the water outlet-side cover member 620 may be inserted in the above-mentioned coupling groove 612 of the water inlet-side cover member 610 so that the water outlet-side cover member 620 may be coupled to the water inlet-side cover member 610.
  • the shape of the coupling protrusion 622 is not particularly limited, and any shape may be used as long as the coupling protrusion 622 may be inserted in the coupling groove 612 of the water inlet-side cover member 610.
  • An installation hole 623 may be formed in the water outlet-side cover member 620.
  • a bimetal (not illustrated) may be installed in the installation hole 623, or an electric wire or the like connected to the heater 420 may pass through the installation hole 623.
  • use of the instantaneous heating apparatus may allow the passage forming member to come into close contact with the heating part by the close-pressing part so as to form the heating passage, in which water is heated while flowing, formed between the heating part and the passage forming member, may significantly reduce the deformation of the heating passage, may significantly reduce the occurrence of water splashing when the water flowing in the heating passage is locally overheated and discharged to the outside, and may prevent user accidents such as burns caused by water splashed, caused by overheating.
  • the instantaneous water heater as described above is not limited in its application of the configurations of the foregoing embodiments, but the entirety or a portion of the embodiments can be selectively combined to be configured to have various modifications.
