Abstract
Description
- The present disclosure relates to a hot water generator.
- Generally, a hot water generator provided in a bidet includes a housing, a ceramic heater mounted in the housing, and a fixing member for fixing the ceramic heater to the housing.
- The housing and the ceramic heater have a cylindrical shape, and are usually disposed coaxially. The fixing member is provided with a water inlet communicating with an inside of the ceramic heater, and a housing having a water outlet.
- Therefore, water flowing into the water inlet passes through the inside of the ceramic heater, flows along the outside of the ceramic heater, and is discharged through the water outlet.
- When water flows inside the ceramic heater, the water is heated while in contact with an inner wall of the ceramic heater. When water flows outside of the ceramic heater, the water is heated while in contact with an outer wall of the ceramic heater, and the heated water is discharged to the water outlet.
- However, the hot water generator thus configured has a simple flow path, such that water passing through the heater does not sufficiently contact a heat generating surface of the heater, which causes heat a waste of heat.

- Hereinafter, embodiments in the present disclosure will be described hereinafter with reference to the accompanying drawings. The disclosure may, however, be exemplified in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the same reference numerals will be used throughout to designate the same or like elements, and the shapes and dimensions of elements may be exaggerated for clarity.

FIG. 1 is a perspective view illustrating a hot water generator according to a first embodiment of the present disclosure,FIG. 2 is an exploded perspective view illustrating a hot water generator according to a first embodiment of the present disclosure, andFIG. 3 is a front view illustrating one end portion of a housing provided in the hot water generator according to a first embodiment of the present disclosure. - Referring to
FIGS. 1 to 3 , ahot water generator 100 according to an embodiment of the present disclosure may include ahousing 120 and aheater 160. - The
housing 120 has awater inlet 122 and awater outlet 124 and has an internal space. Meanwhile, thehousing 120 may include abody 130 having first and secondtubular portions heater 160 is insertedly disposed, acap member 140 coupled to one end of thebody 130, and aheater installation member 150 coupled to the other end of thebody 130 and having theheater 160 installed thereon. - Meanwhile, in the present embodiment, although a case in which the first and second
tubular portions tubular portions tubular portions - In addition, the
water inlet 122 is formed at one end portion of the firsttubular portion 132, and thewater outlet 134 is formed at one end portion of the secondtubular portion 134. - Water flows into the first
tubular portion 132 through thewater inlet 122 and flows into the secondtubular portion 134 passing through the firsttubular portion 132. Thereafter, water passes through the secondtubular portion 134 and flows outside of the housing through thewater outlet 124 of the secondtubular portion 134. - In addition, the
housing 120 may be provided with a helicalflow formation unit 136 which enables the water flowing into the internal space to helically spin and flow along an external surface of theheater 160. - The helical
flow formation unit 136 may be composed of a protrusion or a groove formed on the internal surfaces of the first and secondtubular portions - Meanwhile, a pitch P1 of the helical
flow formation unit 136 formed on the internal surface of the firsttubular portion 132 and a pitch P2 of the helicalflow formation unit 136 formed on the internal surface of the secondtubular portion 134 may be the same as each other. - A
flow path portion 138 for guiding the flow path of water is provided at one end of thebody 130. An interval (a) of theflow path portion 138 connected to the firsttubular portion 132 may be greater than an interval (b) of theflow path portion 138 connected to the secondtubular portion 134. - For example, a ratio of the interval (a) of the
flow path portion 138 connected to the firsttubular portion 132 and the interval (b) of theflow path portion 138 connected to the secondtubular portion 134 may be 2:1. - Accordingly, a flow rate of water, being slowed, passing through the first
tubular portion 132 may be increased through theflow path portion 138 to flow into the secondtubular portion 134, such that the water may smoothly pass through the secondtubular portion 134. - For example, the helical
flow formation unit 136 may be formed to have an angle of approximately 60 to 70 degrees with respect to a horizontal surface. Further, a helical pitch interval of the helicalflow formation unit 136 may be, for example, approximately 9 to 11 mm. - Meanwhile, when the helical pitch interval of the helical
flow formation unit 136 is narrow, a pressure loss may be generated and a hot water stagnation section may be generated. Therefore, as described above, since the helical pitch interval of the helicalflow formation unit 136 is approximately 9 to 11 mm, it is possible to reduce occurrence of the hot water stagnation section. - The
heater 160 is disposed in the internal space of thehousing 120. Meanwhile, theheater 160 may include afirst heater 162 disposed inside the firsttubular portion 132 and asecond heater 164 disposed inside the secondtubular portion 134. - For example, the first and
second heaters heater installation member 150, and the first andsecond heaters - Meanwhile, for example, a minimum interval between an external surface of the
first heater 162 and an internal surface of the firsttubular portion 132 may be approximately 1 mm. - In other words, when the minimum interval of the
first heater 162 and the firsttubular portion 132 may be approximately 0.5 mm, pressure loss may be increased by approximately 30%, thereby affecting a water outlet flow rate and generating the hot water stagnation section. - However, since the minimum interval between the
first heater 162 and the firsttubular portion 132 is approximately 1 mm or more, it is possible to reduce occurrence of the hot water stagnation section due to the pressure loss in the firsttubular portion 132. - In addition, the minimum interval between the
second heater 164 and the secondtubular portion 134 may also be approximately 1 mm. - As described above, the helical
flow formation unit 136 enables the water flowed into thehousing 120 to helically spin and flow along an external surface of theheater 160. - Accordingly, the efficiency of the
heater 160 may be increased by increasing a contact time between the water and theheater 160, such that how water of a target temperature may be obtained. - Hereinafter, a hot water generator according to a second embodiment of the present disclosure will be described with reference to the drawings.
- Meanwhile, the same elements as those described above are replaced with the above description, and the drawings and detailed description thereof will be omitted here.
-
FIG. 4 is a partially cutaway perspective view illustrating a body of a housing provided in a hot water generator according to a second embodiment of the present disclosure. - Referring to
FIG. 4 , a pitch P1 of a helicalflow formation unit 236 formed on an internal surface of a firsttubular portion 232 may be greater than a pitch P2 of a helicalflow formation unit 236 formed on an internal surface of a secondtubular portion 234. - Accordingly, the flowing water may be smoothly helically spun from a
water inlet 222 to awater outlet 224 and flowed. In other words, since a pitch of the helicalflow formation unit 236 at the secondtubular portion 234 is reduced, a flow velocity, being slowed at the secondtubular portion 234, may be increased, such that the water may be helically spun and the water may be smoothly flowed. - As described above, the water flowed into the housing 120 (referring to.
FIG. 2 ) through the helicalflow formation unit 236 may be helically spun along the external surface of theheater 160 and may be flowed. Accordingly, the efficiency of theheater 160 may be increased by increasing the contact time between the water and theheater 160, such that hot water of a target temperature may be obtained. - While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the scope of the present invention, as defined by the appended claims.
