  • the heating device includes a housing having an inlet for letting in fluid and an outlet for letting it flow out, a heat exchange channel installed in the housing and communicating with the inlet, and a heat exchange channel And a heater for heating the fluid therein. Furthermore, a temperature buffer provided in the housing and in communication with the outlet, and a through hole provided between the heat exchange channel and the temperature buffer, and including one or more in communication between the heat exchange channel and the temperature buffer Equipped with The heat exchange channel guides the fluid flowing from the inlet, allows the heated fluid to flow from the through hole into the temperature buffer, and the temperature buffer guides the fluid flowing from the through hole to the outlet. It is also good.
  • the temperature buffer unit is installed, and the heat exchange flow path and the temperature buffer unit are communicated via one or more through holes.
  • water can be more uniformly introduced into the temperature buffer from the through holes, and as a result, the temperature of the hot water flowing from the heat exchange flow passage can be made uniform in the temperature buffer.
  • the space occupied by the temperature buffer can be reduced.
  • the temperature of the hot water can be equalized, and the heat exchange channel and the temperature buffer can be integrated to realize a miniaturized heating device.
  • the heating device of the present invention may further include a mixing rib in the temperature buffer.
  • the flow of hot water flowing in the temperature buffer is inhibited by the mixing rib while flowing in the temperature buffer.
  • the warm water flowing from the through hole and flowing in the temperature buffer is further mixed in the gap between the mixing rib and the inner wall of the temperature buffer and the temperature buffer without the mixing rib.
  • the temperature of the hot water can be made more uniform and flow out from the outlet.
  • the mixing rib may be provided at a position closer to the outlet than at least the through hole at a position farthest from the outlet.
  • the flow direction of the hot water flowing in the temperature buffer can be more effectively blocked.
  • warm water having uneven temperature can be further mixed and made uniform.
  • the heater may be installed at a position not in contact with the wall surface of the heat exchange channel in the heat exchange channel. This allows the water to be heated on both sides of the heater. As a result, the heating speed can be accelerated to supply hot water instantaneously.
  • the inlet and the outlet of the housing are located at positions where the flow direction in which the fluid flows from the inlet into the heat exchange channel and the flow direction in which the fluid flows out from the temperature buffer to the outlet. You may provide. Thereby, the balance between the fluid flowing into the temperature buffer from the through hole and the fluid flowing out can be maintained. As a result, it is possible to efficiently flow warm water into the temperature buffer without stagnating the fluid in the heat exchange channel.
  • the flow direction of the fluid flowing into the temperature buffer from the through hole may cross the flow direction of the fluid in the temperature buffer.
  • the fluid flowing in the temperature buffer and the fluid flowing from the through hole can be gradually mixed.
  • the temperature can be made uniform when flowing out of the outlet.
  • the toilet seat body mounted on the Western-style toilet bowl and pivoted with the seat portion, and the seat portion rotated about the toilet seat body, the above heating provided in the toilet seat body
  • the apparatus may include a water supply unit that supplies water from a water supply source to the heating apparatus, and a nozzle that cleans the human body using warm water heated by the heating apparatus.
  • the warm water of uniform temperature generated by the heating device can be jetted from the nozzle.
  • miniaturization of the sanitary washing device can be realized.
  • the installation of this invention may be equipped with the said heating apparatus.
  • generated by the heating apparatus can be injected from an installation.
  • miniaturization of equipment can be realized.
  • the present invention is useful in the fields of a heating device where production of warm water of a small size and uniform temperature is required, and a sanitary washing device and equipment comprising the same.
