Description

DESCRIPTION

Heating device and sanitary washing device with said heating device

Technical field

The present invention relates to a heating technique, and more specifically to a heating device and a sanitary washing device and equipment using it.

Background technique

Traditionally, in a so-called instantaneous heat exchanger arranged in, for example, a sanitary washing device when there is uneven heating of the hot water emitted from the heat exchanger, a temperature of the water that must be expelled from a washing nozzle is stabilizes before expulsion. This allows a user to conveniently and safely carry out the washing. Specifically, a temperature stabilizer is arranged between an emission part of the heat exchanger and the washing nozzle to absorb the lack of temperature uniformity. There are disclosed sanitary flushing devices that prevent the flushing water from reaching an uneven temperature, being expelled from the flushing nozzle (for example, refer to Japanese Patent No. 3714060 and Unexamined Japanese Patent Publication No. 2000- 1896).

A sanitary washing device has also been disclosed which presents a configuration in which a water inlet piece of the temperature stabilizer is formed by adopting a circular arc profile to accelerate the mixing of hot water in the temperature stabilizer to stop this quickly achieves a uniform temperature of the hot water emitted from the temperature stabilizer (eg, Japanese Unexamined Patent Application No. 2009-235792).

The temperature stabilizer disclosed in each of the referred patent literatures, temporarily stores and mixes the water heated by the heating device within the temperature stabilizer to make the water temperature uniform. In this case, the temperature stabilizer is required to have a volume (capacity) to ensure a certain amount of hot water. Thus a conventional sanitary washing device typically employs a structure in which the temperature stabilizer and the heating device are located separately.

At present, a temperature stabilizer of a sanitary washing device is essential to achieve, in a comfortable and safe way, a hot water wash.

EP 2476 969 A1 discloses a heat exchanger capable of suppressing scale formation and adhesion while achieving a higher heat transfer rate and a longer service life. The heat exchanger includes throttling passages having smaller cross-sectional areas of flow passage than another section between an upstream space and a downstream space, and a plate heater configured such that a generating density of heat is less in a portion closer to a water outlet than in a portion closer to a water inlet. This makes it possible to prevent a temperature from rising to an elevated temperature at which local boiling takes place, even in a boundary layer between a portion of the plate heater that is closest to the water outlet, where the water temperature of Flushing tends to be high, and flushing water contacts the portion of the plate heater that is closest to the water outlet, while improving the heat transfer rate. As a result, the generation of air bubbles is suppressed, and the generated air bubbles are quickly guided to the water outlet. Thus, this heat exchanger can prevent scale formation and scale adherence in the plate heater and offers a longer service life.

WO 2011/086911 A1 discloses a heating device comprising a first casing and a second casing, said first casing containing heating elements, said second casing containing the first casing and presenting a flow path between the second casing and the first casing, and said flow path serving as a flow path as a means of heating the heating elements.

However, the structure in which the temperature stabilizer and the heating device are placed separately, results in the presence of a large space occupied by the entire water heater in the sanitary washing device. Thus, the use and coupling are disadvantageously impractical.

To solve the exposed problem, the temperature stabilizer and the heating device can be integrated to achieve a reduction in size. However, when the temperature stabilizer and the heating device are integrated, it is necessary to ensure a space to arrange the temperature stabilizer so that it presents a considerable volume within the design heating device. That is, in integrating into a conventional heating device, even when an arrangement relationship between the heating element and the flow path is achieved to be optimal in order to efficiently carry out the heat change, a configuration such as for example, a temperature stabilizer in which a certain capacity is ensured to eliminate the non-uniformity of the temperature. It is not like that It is possible to achieve space savings and therefore it is not possible to achieve size reduction. Therefore, an objective to reduce the size of a water heater while securing a space to provide a temperature stabilizer has not yet been met.

Summary of the invention

The invention is defined by the independent claim. The dependent claims represent preferred embodiments of the invention.

An advantageous embodiment of the invention provides a heating device that allows a more stable temperature of the hot water that comes out and also allows the reduction of size, and a sanitary washing device and equipment that uses it.

The heating device according to the invention is provided with a casing having an inlet port to allow the fluid to enter and an outlet port to allow the fluid to exit, a path of the heat exchange flow that is located within from the housing and communicating with the inlet port, and a heater that heats the fluid inside the heat exchange flow path. The heating device is also provided with a temperature regulating part that is located inside the housing and communicates with the outlet port and one or more through holes that are formed between the path of the heat exchange flow and the regulating part. temperature and communicates between the path of the heat exchange flow and the temperature regulating part. The heat exchange flow path guides the fluid entering through the inlet port and allows the fluid, after being heated, to flow into the temperature regulator piece through the through holes and the flow regulator piece. the temperature guides the fluid that enters through the through holes to the outlet hole.

In this configuration, the temperature regulating part is located within the housing, and the heat exchange flow path and the temperature regulating part communicate with each other through the through holes. Accordingly, the temperature of the hot water flowing into the temperature regulating part from the heat exchange flow path can be made to be uniform in the temperature regulating part. Likewise, a space occupied by the temperature regulating piece can be reduced. As a result, it is possible to achieve that the heating device in which the temperature of the hot water is uniform, and that the path of the heat exchange flow and the temperature regulating part are integrated to reduce the size of the heating device. heating.

In accordance with the invention, a plurality of mixing ribs are arranged in the temperature regulating part whereby the plurality of mixing ribs is equal to the plurality of the through holes between the path of the flow of change of heat and temperature regulating part.

The plurality of mixing ribs have a substantially semilunar cross section, in which the upstream side of each of the ribs has a rounded projection shape without any corner piece. The downstream side of the ribs is formed by adopting a shape substantially set back towards the outlet port so that the wash water flows along the rounded projection shape of the mixing rib, and then flows to one side. interior of the set back piece. This allows for improved mixing of hot and cold water so that the water reaches a uniform temperature at the outlet port.

Description of embodiments

Exemplary embodiments of the present invention will now be described with reference to the drawings. Exemplary embodiments are merely examples and the present invention is not limited by exemplary embodiments.

First exemplary embodiment

Next, it will be described, with reference to FIGS. 1 to 2F, a configuration of a heating device in a first exemplary embodiment of the present invention. In the heating device of the present exemplary embodiment, water is described as an example of fluid flowing through the internal heating device. However, it goes without saying that the fluid is not limited to water. For example, a liquid other than water can be used, for example water with the addition of a medicament or a washing agent and water or functional gas.

2D.

As illustrated in FIGS. 1 to 2F, a heating device 1 of the present exemplary embodiment includes at least one housing 13, a mixing rib 22, a heat exchange flow path 24, a heater 23, a temperature regulating part 25 and the like, elements that are arranged within the casing 13. The through hole 21 is formed between the path 24 of the heat exchange flow and the temperature regulating part 25. The water heated by the heater 23 flows through the temperature regulating part 25. As illustrated in FIG 1, the heating device 1 is formed adopting, for example, a rectangular parallelepiped shape, and both side faces on its long sides are located in the up and down directions.

The housing 13 is provided with an inlet hole 11 which is located on a lower part of the housing 13 to allow water to enter and an outlet hole 12 which is located on an upper part of the housing 13 to allow water out. In the present exemplary embodiment, an example in which the inlet port 11 and the outlet port 12 are illustrated are arranged on the same side face in the right and left directions of the housing 13.

Path 24 the heat exchange flow is formed within housing 13 and communicates with inlet port 11. Heater 23 is, for example, a flat heater made of ceramic material. As illustrated in FIGS. 2E and 2F, the heater 23 is partially supported and arranged within the heat exchange flow path 24 so that an entire face of the heater 23 does not contact both the wall surface 26a and the wall surface 26b path 24 of the heat exchange flow. Heater 23 heats the water flowing through the heat exchange flow path 24 on both sides of heater 23 as primary heating surfaces. The water flowing inside the heat exchange flow path 24 flows upward along both faces of the heater 23 to an upper end of the heater 23, and the water flowing upward along the one side and the water that flows along the other side. Subsequently, the water passes through the through hole 21 that faces a terminal face of the heater 23 and flows through the interior of the temperature regulating part 25. The temperature regulating part 25 is located above the path 24 of the heat exchange flow inside the housing 13 and communicates with the outlet port 12. As described above, the through hole 21 is formed between the heat exchange flow path 24 and the temperature regulating part 25, and communicates between the heat change flow path 24 and the temperature regulating part 25.

As illustrated in FIG. 2D, the mixing rib 22 is disposed within the temperature regulating part 25 to narrow a flow path for the hot water entering through the through hole 21. In the present exemplary embodiment, a plurality of ribs 22 Mixing is equal to a plurality of through holes 21 (five in FIG. 2D). The mixing rib 22 is disposed between the corresponding adjacent through hole 21 and the outlet hole 12. The mixing rib 22 may have, for example, a shape whose width in cross section increases in the direction of the outlet hole 12 (not shown). This shape reduces a distance between an inner wall of the temperature regulating part 25 and the mixing rib 22 towards the outlet port 12 and, thus, further obstructs a flow of water. As a result, the water exhibiting a non-uniform temperature can be sufficiently mixed within the temperature regulating part 25. That is, the hot water flows through a narrow flow path formed in the temperature regulating part 25 by mixing the rib 22 and a wide flow path over the other part. Therefore, it is possible to mix the hot water to eliminate the lack of temperature uniformity. Next, a specific operation will be described.

The heat exchange flow path 24 guides the water entering through the inlet port 11 and allows the water heated by the heater 23 to enter the temperature regulating part 25 through the through hole 21. Likewise, the temperature regulating part 25 guides the heated water entering through the through hole 21 to the outlet hole 12 while mixing the water heated by the mixing rib 22 to be fed, for example, to a nozzle of a sanitary washing device. Although, in the present exemplary embodiment, a space formed by the housing 13 is used as path 24 of the heat exchange flow, the present invention is not limited to this configuration. For example, the heat exchange flow path 24 may be configured as a single member located independently within the housing 13. This configuration makes it possible to more accurately set a width of the heat exchange flow path 24 heat, that is, a size of space between path 24 of the heat exchange flow and heater 23.

The heating device of the present exemplary embodiment is configured as described above.

Next, it will be described, with reference to FIG. 3, the operating principle of a heating device that includes a plurality of through holes, that is, for example, four through holes.

FIG. 3 is a schematic view of a direction of the water flow of the heating device having a plurality of through holes

In the heating device having a configuration illustrated in FIG. 3, the water flows in a direction indicated by the arrow F ¹ . At this time, water flows inside the temperature regulating part 25 through region 24c near through hole 21a and region 24d near through hole 21d. In this case, four through holes 21a are formed and one area of each of the through holes 21 is an extremely small area having a diameter, for example, 2.4 mm. Thus when the water enters through the through holes 21a to 21d a pressure loss occurs. Since the needle flows along the direction of flow indicated by arrow F ¹ in FIG. 3, the pressure loss is greater within the through hole 21a and smaller in the through hole 21d. That is, the pressure loss presents a ratio of the through holes 21a>21b>21c> 21d. Consequently, the water in region 24e tends to flow into the temperature regulating part 25 through the through hole 21d with a relatively small pressure loss. Thus, it is possible to prevent the formation of a stagnation part in the region 24e. Likewise, long-term heating of water in region 24e is prevented. Accordingly, it is possible to prevent a water temperature in region 24e from increasing excessively. That is, when the temperature increases excessively, scale builds up within the heat exchange flow path 24 due to the rise in local temperature. As a result the flakes adhere to the flow path to narrow the flow path or adhere to the face of the heater to cause a negative effect on the heating surface.

These negative effects can be prevented by allowing the water to flow efficiently inside the temperature regulating part 25 without generating the stagnant part on the heating surface.

The water entering the through holes 21a to 21d from the heat exchange flow path 24 is mixed within the temperature regulating part 25. Thus, an equilibrium (uniformity) of the water temperature can be achieved before the water exits through the outlet port 12 of the temperature regulating part 25. As a result, it is possible to allow the water to offer a uniform temperature for it to exit through the outlet port 12.

It will now be described as an example with reference to FIG. 4 the operating principle of a heating device which is provided with four mixing ribs 22 corresponding to the four through holes of FIG. 3.

FIG. 4 is a schematic view of a direction of water flow in a temperature regulating part that has several mixing ribs, which, however, do not have the shape required by the invention and therefore are not included in the scope of the invention.

For easy understanding, FIG. 4 illustrates, in an enlarged form, a proximity of the temperature regulating part 25 that has mixing ribs 22a to 22d each of which has a rectangular cross section.

As illustrated in FIG. 4, when four mixing ribs 22a to 22d are located within the temperature regulating part 25, the mixing ribs 22a to 22b obstruct a flow of water to the outlet port 12 as indicated by arrows F ² , which which causes a mixed flow. Accordingly, the water is mixed as it flows into the outlet port 12. As a result, the temperature of the water exiting through the outlet port 12 becomes more uniform. That is, the incorporation of the plurality of mixing ribs 22a to 22d corresponding to the plurality of through holes 21a to 21d allows the water temperature to be more uniform within the temperature regulating part 25.

Next, it will be described in more detail, with reference to FIG. 5, the operating principle of the heating device provided with four mixing ribs indicated in FIG. Four.

FIG. 5 is a schematic view of the entire direction of the water flow within the heat exchange flow path and of the temperature regulating part incorporating the plurality of mixing ribs. The mixing ribs, however, have a shape that is not included in the scope of the invention.

In FIG. 5, the number of through holes is equal to the number of mixing ribs, namely four. In this case, the mixing rib 22a is arranged adjacent to the through hole 21a facing the outlet hole 12. Similarly, the mixing ribs 22b, 22c and 22d are respectively arranged in correspondence with the adjacent through holes 21b, 21c and 21d on the side facing the outlet hole 12.

As previously described with reference to FIG. 3, due to the principle of pressure loss the water flowing in the path 24 of the heat exchange flow indicated by arrows F ¹ , F ³ , F ⁴ and F ⁵ in FIG. 5 enters the temperature regulating part 25 through the through hole 21d, through the hole 21c, through the hole 21b and through the hole 21a, in this order, that is, in an ascending order of pressure loss. Next, the water entering the temperature regulating part 25 from the path 24 of the heat exchange flow through the through holes 21d to 21a flows to the outlet hole 12 while it is mixed with the water previously existing inside the temperature regulating part 25. At this time, since the diameter of each of the through holes 21a to 21d is extremely small, a velocity of the flow of the water entering through the through holes 21d to 21a is relatively high. Thus, the water entering the temperature regulating part 25 and the water inside the temperature regulating part 25 are easily mixed. Accordingly, the water entering the temperature regulating part 25 from the heat exchange flow path 24 and the water previously existing inside the temperature regulating part 25 are easily mixed to achieve a uniform temperature. As a result, it is possible to allow the water to have a uniform temperature to exit through the outlet port 12 of the heating device 1.

As illustrated in FIG. 5, since the mixing ribs 22a to 22d are located within the temperature regulating part 25, the mixed flow can be further generated in the flow of the water within the temperature regulating part 25. As a result, it is possible to allow the water having a more uniform temperature to flow out through the outlet port 12.

Although, in the present embodiment, the configuration in which the heater 23 is arranged without contact with both the wall surface 26a and the wall surface 26b of the heat exchange flow path 24 has been described by way of For example, the present invention is not limited to this configuration. For example, heater 23 may be located on a wall surface of heat change flow path 24 as schematically described below. That is, the heater 23 can be located in any position that allows the heater 23 to heat the water inside the path 24 of the heat exchange flow.

Other examples of heater arrangement will be specifically described with reference to FIGS. 6A to 6C. FIG. 6A is a schematic view of a heater in accordance with a modification of the first exemplary embodiment of the present invention when it is arranged on an inner side of one side of the housing. FIG. 6B is a schematic view of the heater when it is arranged on an outer side of one side of the housing. FIG. 6C is a schematic view of the heater when it is disposed laterally on the bottom of the heat exchange flow path.

First, as illustrated in FIG. 6A, the heater 23 is placed in intimate contact with an interior wall within the heat exchange flow path 24 with the heating surface 23a facing the heat exchange flow path 24. This configuration makes it possible to efficiently heat the water flowing through the heat exchange flow path 24. Also, the heater 23 can be easily coupled and stably arranged.

As illustrated in FIG. 6B the heater 23 can be adhered to an outer wall surface outside of the heat exchange flow path 24 with the heating surface 23a adhered to the outer wall surface. In this case, since a space inside the casing 13 is used as path 24 of the heat exchange flow, the heater 23 adhering to an exterior wall outside the path 24 of the heat exchange flow corresponds to the adhesion of heater 23 to an exterior wall of casing 13. This configuration increases a capacity of path 24 of the heat exchange flow, allowing an increase in an amount of hot water.

As illustrated in FIG 6C, the heater 23 may be disposed, for example, laterally on the bottom of the heat exchange flow path 24 with the heating surface 23a facing the heat exchange flow path 24. This configuration makes it possible to efficiently heat the water flowing through the heat exchange flow path 24 in the same manner as in the configuration illustrated in FIG. 6A. Also, the heater 23 can be easily fixed and stably arranged.

The present invention is not limited to the examples illustrated in FIGS. 6A to 6C, in which only one heater 23 is provided with respect to the path 24 of the heat exchange flow. One or more heaters 23 may be provided. This configuration makes it possible to more efficiently heat the water flowing through the heat exchange flow path 24.

Although, in the present exemplary embodiment, an example has been described in which the space formed by the housing is used as the path of the heat exchange flow, the present invention is not limited to this configuration. For example, when the heat exchange flow path is located independently within the housing, the heater may be attached to an exterior wall outside the heat exchange flow path. In this case, the heater is located on the outer wall of the heat exchange flow path located between the housing and the heat exchange flow path. This configuration makes it possible to efficiently heat the heat exchange flow path.

Although in the present exemplary embodiment, an example has been described in which the inlet port 11 and the outlet port 12 are arranged on the housing such that a direction of flow of the water entering the flow path 24 Heat exchange through the inlet port 11 is opposite to a direction of flow of the water leaving in the direction of the outlet port 12 from the temperature regulating part 25 as illustrated in FIGS. 3D, 3 and 5, the present invention is not limited to this configuration. For example, inlet port 11 and outlet port 12 may be arranged on housing 13 in the manner described below with reference to FIGS. 7A and 7B.

FIG. 7A is a schematic view of a heating device in which a direction of the flow of the water entering through an inlet port is the same as a direction of the flow of the water exiting through the outlet port. This heating device is not included in the scope of the invention since the mixing ribs are rectangular.

FIG. 7B is a schematic view of a heating device in which a direction of the flow of the water entering through an inlet port intersects a direction of the flow of the water leaving through an outlet port. This heating device, once again, is not included in the scope of the invention, insofar as the mixing ribs are rectangular.

That is, as illustrated in FIG. 7A, the inlet hole 11 and the outlet hole 12 of the casing 13 can be arranged such that the direction of the flow of the water entering through the inlet hole 11 is the same as the direction of the water flow that exits through outlet port 12. This configuration allows the stabilization of the temperature of the water that comes out in the same way explained above.

As illustrated in FIG. 7B, the inlet hole 11 and the outlet hole 12 of the casing 13 can be arranged such that the direction of the flow of the water entering through the inlet hole 11 crosses the direction of the flow of the water leaving through the outlet hole 12. Here, "intersection" is, for example, a relationship in which water enters inlet port 11 along a horizontal direction and exits through outlet port 12 along a vertical direction, as illustrated in FIG. 7B. However, the intersection is not limited to this relationship. It goes without saying that any oblique direction that crosses the horizontal direction can be used. Therefore, the same effect can be obtained as the referred one.

In accordance with the invention, as illustrated in FIG. 2D, the mixing ribs 22 have a substantially semilunar cross section (including a semilunar cross section). An upstream side of the mixing rib 22 has a rounded projecting shape without any corner pieces and therefore offers less pressure loss. Likewise, a downstream side of the mixing rib 22 is formed adopting a substantially set back configuration (including a set back shape) towards the outlet port 12. Accordingly, when the water enters through the through hole 21 and flows through the temperature regulating part 25 in the direction of the outlet hole 12, a washing water flows along the rounded projection shape of the rib. 22 and then flows in the direction of an inner side of the set piece to be mixed. That is, the shape of the mixing rib 22 shown in FIG. 2D allows a sharp acceleration of the mixture to achieve a uniform temperature.

In the present exemplary embodiment, as illustrated in FIGS. 2D and 2E, the heating device 1 is provided with a temperature regulating part 25 that communicates with the outlet port 12 and the plurality of holes 21 that are located between the path 24 of the heat exchange flow and the part Temperature regulator 25 to allow the heat exchange flow path 24 to communicate with each other. The plurality of through holes 21 is formed at intermediate positions between the heat exchange flow path 24 and the temperature regulating part 25. The plurality of mixing ribs 22 are arranged on the downstream side of the respective through holes 21. Each of the mixing ribs 22 has a cross-sectional shape with a substantially rounded projecting part without any angular portion on the side. upstream and has a cross-sectional shape with a portion substantially set back on the downstream side. This configuration features high mixing and stirring effects with less pressure loss. Thus, it is possible to achieve a uniform hot water temperature with less lack of temperature uniformity. At the same time, the heat exchange flow path and the temperature regulating part can be integrated to achieve a further decrease in size.

Likewise, each mixing rib is not necessarily arranged in correspondence with each through hole on the side facing the outlet hole. Each mixing rib can be arranged in any position that allows the mixing rib to effectively obstruct a flow of water to effectively mix water with a non-uniform temperature within the temperature regulating piece.

As described above, in the present exemplary embodiment the temperature regulating part is located within the housing and the through hole allowing the heat exchange flow path and the temperature regulating part to be formed so that communicate with each other. This configuration makes it possible to get the temperature of the hot water to flow uniformly inside the temperature regulating part. Likewise, a space occupied by the temperature regulating piece can be reduced as much as possible. Thus, the heating device which is provided with both the heat exchange flow path and the temperature regulating part can easily be reduced in size.

Second exemplary embodiment

It will now be described with reference to FIG. 8 a sanitary washing device with the heating device according to the present invention.

The sanitary washing device can be a sink device, a washing device such as a bathtub, an instant water heater or a water server provided with the heating device described in the first exemplary embodiment referred to. Likewise, the equipment includes equipment that requires the provision of fluid at a stable temperature.

A sanitary washing device will now be described in detail.

The sanitary wash device of the present exemplary embodiment is an instant wash device that heats the flowing water to generate hot water and differs from a sanitary wash device type storage that stores hot water in a tank. An instant sanitary flushing device typically has a water flow rate of approximately 400-500 ml per minute and generates hot water by means of a heating device to flush intimate parts of the human body.

FIG. 8 is a perspective view of the sanitary washing device according to the second exemplary embodiment of the present invention to which the heating device is attached.

As illustrated in FIG. 8, the sanitary wash device 100 of the present exemplary embodiment includes at least one toilet seat body 101, a water supply device (not illustrated), an operating part 104, a nozzle 105, and the like. The toilet seat body 101 is pivotally connected to the seat part 102 to allow the seat part 102 to pivot on the toilet seat body 101. The toilet seat body 101 is mounted on the western style toilet bowl 103. The heating device 1 described in the first exemplary embodiment is arranged within the toilet seat body 101. In this case, the heating device 1 is arranged in such a way that the flat heater of a heat exchanger is vertically positioned inside the toilet seat body 101. Accordingly, the inlet port 11 of the heating device 1 is located on the underside of path 24 of the heat exchange flow, and the outlet port 12 is located on the top side of path 24 of the heat exchange flow. .

Next, the operation of the sanitary washing device according to the present exemplary embodiment will be described.

When washing is carried out using the sanitary washing device 100, a user first operates the operating part 104. Accordingly, the water feeding device introduces water into the heating device 1 from a water feeding source.

Therefore it is possible to allow hot water with a more uniform temperature to flow out through the outlet port. In the heating device of the present invention, the mixing rib may be disposed between the outlet port and at least through one through hole (s) located further away from the outlet port. . This configuration makes it possible to more effectively obstruct the direction of the flow of the hot water entering the temperature regulating part. As a result, hot water with a non-uniform temperature can be further mixed to make it uniform.

In the heating device of the present invention, the heater may be disposed within the heat exchange flow path in a position that is not in contact with a wall surface of the heat exchange flow path. This configuration makes it possible to heat the water on both sides of the heater. As a result, it is possible to increase the heating rate to instantaneously supply hot water.

In the heating device of the present invention, the inlet port and outlet port of the housing may be arranged in positions that cause a direction of flow of the fluid flowing into the path of the heat exchange flow to Through the inlet hole it is opposite to a direction of the flow of the fluid that leaves towards the outlet hole of the temperature regulating part. This configuration makes it possible to maintain a balance between the fluid that enters the temperature regulating part through the through hole (s) and the fluid that leaves the temperature regulating part. As a result, it is possible to allow hot water to flow efficiently into the temperature regulating part without causing the fluid to stagnate within the path of the heat exchange flow.

In the heating device of the present invention, a direction of flow of the fluid flowing within the temperature regulating part through the through hole (s) can cross a direction of fluid flow in the inside of the temperature regulating piece. This configuration makes it possible to gradually mix the fluid flowing inside the temperature regulating part with the fluid flowing inside the temperature regulating part through the through hole (s). As a result, the water temperature can be made to be uniform when the water exits through the outlet port.
