Description

  The present invention relates to a heat source machine that can prevent noise generation during driving.

  2. Description of the Related Art A heat source apparatus that has a combustion chamber that contains a combustion burner and that ignites and burns the burner while supplying combustion air from the outside into the combustion chamber is widely known.

  In such a heat source machine, combustion air corresponding to the burner combustion amount is generally supplied to the combustion chamber by a blower or the like, and combustion gas generated by the burner combustion is exhausted to the outside. Further, the combustion gas generated by the combustion of the burner in the combustion chamber supplies heat to hot water passing through the heat exchanger, and hot water supplied from a hot water tap such as a curan is supplied.

  In addition, there are multi-function heat source machines that can be used for bathing and floor heating. In this type of heat source device, generally, a hot water is circulated between the bathtub and the heat exchanger to circulate the hot water in the bathtub, or a heat medium is provided between the heater and the heat exchanger. It has a heating circulation circuit that supplies heat to the heating appliance via a heat medium by circulation.

In this type of heat source machine, even the latent heat of the combustion gas is recovered, so that the water vapor in the combustion gas becomes liquefied and drainage is generated. Then, when the generated drain is exposed to the combustion gas, nitrogen oxide (NOx) or sulfur oxide (SOx) is taken in from the combustion gas and exhibits strong acidity.
In view of this, some heat source machines of this type have a structure that neutralizes this acidic drain. For example, Patent Document 1 discloses the structure thereof.
In the heating apparatus (heat source machine) disclosed in Patent Document 1, the neutral drain is neutralized by staying in the neutralizer filled with the neutralizing agent, and the neutralized drain water is temporarily stored. deep. And when the water level of the neutralized drain water becomes more than a certain level, the drain water is discharged to the outside by driving the drain discharge pump.

  As described above, the heat source device includes a device that generates vibration during driving, such as a blower for sending air into the combustion chamber, a pump for circulating hot water in a bathtub or a heat medium for heating. is there. When these devices vibrate as they are driven, the vibration sound may be greatly affected depending on conditions such as the installation location of the heat source machine and the installation environment, and the user may feel noise.

  Then, this invention makes it a subject to provide the heat source machine which can prevent the noise at the time of a drive in view of the problem of the above-mentioned prior art.

The present inventor has intensively studied to solve the above-described problems, and integrally fixes a device that generates vibration such as a blower or a pump to a member for storing a liquid such as a neutralizer or a drain tank. And found that the vibration can be reduced, and completed the present invention.
More specifically, it is conceivable that a device that generates vibration is reduced by being fixedly attached to a heavy object (device or the like). However, usually, there are devices that are built in the heat source device that generate heat during driving, and devices that interfere with operation when subjected to vibration. For this reason, simply fixing a device that generates vibration to a heavy object built in the heat source device may hinder the operation of the heat source device although vibration is suppressed. Therefore, as a result of studies conducted by the present inventors to reduce vibration without hindering the operation of the heat source machine, it is possible to integrally fix a device that generates vibration to a member for storing liquid, such as a neutralizer or a drain tank. It turned out to be effective.
The present invention for solving the above-described problems is as follows.

  The invention according to claim 1 is a heat source device that has a combustion section provided with at least a burner for combustion, heats hot water or a heat medium and supplies heat, and stores the liquid therein. The liquid storage member includes a storage member and a vibration body that generates vibration, and the liquid storage member and the vibration body are fixed together directly or via a fixing member, so that the vibration generated by the vibration body is the liquid storage member. It is a heat source machine characterized by being transmitted to the liquid stored in.

In the heat source apparatus of the present invention, the vibration generated by the vibrating body is stored in the liquid storing member by fixing the liquid storing member for storing the liquid and the vibrating body integrally directly or via a fixing member. It is structured to be transmitted to the liquid.
The liquid storage member has a heavy weight because the liquid is stored therein, and functions as a weight. Therefore, when the liquid storage member is fixed integrally to the vibration body, the vibration of the vibration body can be suppressed by the force acting from the liquid storage member that is a heavy object.
Further, the liquid stored inside the liquid storage member also acts as a vibration absorber that absorbs the vibration when the vibration of the vibration body is transmitted. Here, when the vibration is propagated to the stored liquid, the liquid surface is in a wavy state. That is, the stored liquid has a property that its shape can be deformed without changing the total volume. In addition, since the vibration body, which is a device built in the heat source device, and the stored liquid have different natural frequencies, they do not resonate with each other. By these things, the liquid stored inside the liquid storage member can reduce the vibration transmitted from the vibrating body.
From the above, noise at the time of driving can be prevented by fixing the liquid storage member and the vibrating body together directly or via a fixing member.
Further, in the present invention, the vibration generated by the vibrating body is transmitted to the liquid stored in the liquid storage member, so that the liquid stored in the liquid storage member can be prevented from freezing. More specifically, when using a heat source device in a cold district where the external temperature is low, it is stored in a liquid storage member such as a hot water or a drain tank that stays in a pipe located inside the heat source device. It is possible that the liquid will freeze. Therefore, in order to prevent such liquid freezing, various freeze prevention measures such as providing a heater at a site where the liquid stays or forcibly forming a circulating flow by starting the pump are usually used. Prevents liquid freezing. Here, in the heat source apparatus of the present invention, the liquid storage member is integrally fixed to the vibration body, and the vibration generated by the vibration body is transmitted to the liquid stored in the liquid storage member. For this reason, the liquid stored in the liquid storage member is difficult to freeze due to the water surface being shaken by vibrations generated by the vibrating body. Therefore, the liquid stored in the liquid storage member does not freeze even if the above-described freezing prevention is not performed (or not frequently performed).
That is, according to the present invention, the vibrating body acts to prevent freezing of the liquid stored in the liquid storage member, and the liquid stored in the liquid storage member and the liquid storage member suppresses vibration of the vibrating body. Act on. Therefore, in the present invention, both the vibrating body and the liquid storage member fixed integrally have a favorable influence on each other.

  According to a second aspect of the present invention, there is provided a primary heat exchanger that mainly recovers sensible heat of a combustion gas generated by operating a burner, and a secondary heat exchanger that recovers mainly latent heat of the combustion gas. A drain drainage system that drains the drain generated in the secondary heat exchanger, the drain discharge system includes a neutralizer for neutralizing and discharging the drain, and the neutralizer The heat source apparatus according to claim 1, further comprising a drain tank for storing a drain formed integrally or separately, wherein the liquid storage member is the drain tank.

In the invention according to claim 2, the liquid storage member for suppressing the vibration of the vibrating body of the neutralizer belonging to the drainage drainage system for discharging the drain or the drain tank integrally or separately formed with such a neutralizer And
Here, the neutralizer built in the heat source device may be used by forming a water-sealed structure by storing a liquid therein before starting operation. That is, even if the combustion gas generated by the combustion operation of the burner enters the neutralizer, the combustion gas is neutralized beforehand in order to prevent the combustion gas from being discharged from the downstream side of the neutralizer drain direction. In some cases, the operation of the heat source machine is started after the liquid is stored in the vessel and a water-sealed trap is formed. Regardless of this, in a heat source machine that can mainly recover latent heat of combustion gas, if the operation of the heat source machine is continued, drainage will continue to be generated in the secondary heat exchanger. The drain continues to flow into the vessel and drain tank. That is, the liquid is continuously stored in the neutralizer and the drain tank before or after the operation is started.
In the present invention, it is preferable to suppress the vibration of the vibrating body by using the liquid storage member that continuously stores the liquid as described above. In detail, the liquid that is constantly stored is maintained in a relatively heavy state, that is, a heavier state than when the liquid is not stored. The vibration can be suppressed.
Further, as described above, the stored liquid also acts as a vibration absorber that absorbs the vibration when the vibration of the vibration body is transmitted. Therefore, when the liquid is always stored, the vibration can be reduced regardless of the driving start timing of the vibrating body.
That is, if the liquid storage member is a liquid storage member that continues to store liquid therein, the vibration can be suppressed at any time after the start of operation of the heat source machine.

  The invention according to claim 3 has a heating circulation circuit for circulating a heat medium between an external heating device and a heat exchanger, and the liquid storage member is an expansion tank attached to the heating circulation circuit. The heat source machine according to claim 1, wherein the heat source machine is provided.

  When the present invention is adopted in a heat source device having a heating circulation circuit that circulates a heat medium between an external heating device and a heat exchanger, an expansion tank may be used as a liquid storage member.

  The invention according to claim 4 is the heat source apparatus according to any one of claims 1 to 3, wherein the vibrating body is a blower for supplying air for combustion to the combustion section. .

  According to a fifth aspect of the present invention, the burner burns liquid fuel, and has a fuel supply pump for supplying liquid fuel to a combustion section, and the vibrator is configured to supply the fuel. The heat source device according to any one of claims 1 to 3, wherein the heat source device is an industrial pump.

  The present invention is preferably employed to reduce vibrations generated by a blower for supplying combustion air to the combustion section, a fuel supply pump for supplying liquid fuel to the burner, and the like.

  In the present invention, a heavy liquid storage member is integrally fixed to a vibrating body that generates vibration. Further, the vibration generated by the vibrating body is propagated to the liquid stored in the liquid storage member, and the vibration is absorbed by this liquid. For this reason, it is possible to suppress the vibration of the vibrating body, which has the effect of preventing noise generation during driving.

It is a lineblock diagram showing the heat source machine concerning the embodiment of the present invention. It is a perspective view which shows the drain tank of FIG. It is explanatory drawing which shows a mode that the drain tank of FIG. 1 is integrally fixed to the air blower of FIG.

  Hereinafter, although the heat source apparatus 1 concerning embodiment of this invention is demonstrated in detail, this invention is not limited to these examples. Further, in the following description, the vertical and horizontal positional relationship will be described based on a normal arrangement state unless otherwise specified.

  As shown in FIG. 1, the heat source unit 1 includes a combustion unit 3 inside the housing 2, a blower 4 (vibrating body) that supplies combustion air to the combustion unit 3, and a primary that mainly recovers sensible heat. This is a so-called latent heat recovery type equipped with a heat exchanger 5 (heat exchanger) and a secondary heat exchanger 6 (heat exchanger) mainly recovering latent heat. In addition, the heat source device 1 includes a control device (not shown), and the control device issues an operation command to each part of the heat source device 1, whereby the heat source device 1 performs various operations.

  The casing 2 includes a top plate portion 10, a bottom plate portion 11, a left side wall portion 12, a right side wall portion 13, a front lid portion (not shown), and a back plate portion 14, all of which are rectangular plates. These are a top plate part 10, a bottom plate part 11, two side wall parts (left side wall part 12, right side wall part 13) and a back plate part 14 forming a box body whose front face is open, The part can be attached so as to cover the open part of the front.

  The combustion unit 3 is configured to generate high-temperature combustion gas by burning fuel such as gas and kerosene supplied from the outside by a burner (not shown).

  The blower 4 incorporates a motor and an impeller (not shown) inside, and can change the number of rotations according to the combustion state of the burner of the combustion unit 3 to adjust the blown amount and the blown pressure.

  The primary heat exchanger 5 is a known gas / liquid heat exchanger, and is disposed downstream of the combustion unit 3 in the flow direction of the combustion gas. The primary heat exchanger 5 is a fin-and-tube heat exchanger whose main part is made of copper and in which hot water flows.

  The secondary heat exchanger 6 is a known gas / liquid heat exchanger, and is a part that recovers the thermal energy of the combustion gas that could not be recovered by the primary heat exchanger 5, and is combusted by the primary heat exchanger 5. It is arranged downstream in the gas flow direction. This secondary heat exchanger 6 is formed by incorporating a pipe (not shown) through which hot water flows inside the box-like body, and stainless steel or the like having high corrosion resistance is adopted as a raw material of this pipe. By doing so, it has a structure superior in corrosion resistance as compared with the primary heat exchanger 5.

  This heat source unit 1 is formed in the combustion unit 3 by forming a space communicating from the inside of the combustion unit 3 to the exhaust port (not shown) through each of the primary heat exchanger 5 and the secondary heat exchanger 6. Combustion gas can flow.

  Therefore, when the heat source unit 1 is operated, the combustion gas generated in the combustion unit 3 reaches the exhaust port 18 through the primary heat exchanger 5 and the secondary heat exchanger 6, and then from an exhaust pipe (not shown). It is discharged outside. On the other hand, hot water supplied from the outside is supplied to the secondary heat exchanger 6 through a water inlet pipe (not shown). Then, hot water is preheated by the secondary heat exchanger 6 and then flows into the primary heat exchanger 5, and is heated by the primary heat exchanger 5. The heated hot water flows out from the water outlet of the primary heat exchanger 5, is mixed with low-temperature hot water as necessary, and is supplied toward a curan, a bathtub, or the like serving as a hot water hot-water tap.

  As described above, since the secondary heat exchanger 6 mainly recovers latent heat of the combustion gas, the temperature of the combustion gas is reduced to a certain value or less in the secondary heat exchanger 6. As a result, water vapor contained in the combustion gas is liquefied and drainage is generated. The generated drain is exposed to the combustion gas, so that nitrogen oxides and sulfur oxides generated by combustion dissolve and exhibit acidity.

  Therefore, the heat source apparatus 1 of the present embodiment has a configuration including a drain discharge system 20 for neutralizing the generated drain and discharging it to the outside.

  The drain discharge system 20 includes a drain pan (not shown) formed at the bottom of the case that houses the secondary heat exchanger 6 in order from the upstream side in the drain flow direction, a neutralizer 21 for neutralizing the drain, The drain tank 22 (liquid storage member) for temporarily storing the drain neutralized by the neutralizer 21 is configured.

  The drain generated in the secondary heat exchanger 6 is neutralized by the neutralizer 21 and then stored in the drain tank 22. When it is detected that the water level in the drain tank 22 has reached a certain level or more, the drain discharge pump 24 is activated, and the drain in the drain tank 22 is located on the downstream side of the drain tank 22. It is discharged to the pipe 25. The drain flows from the drain discharge pipe 25 to the downstream pipe and is discharged to the outside.

  In the heat source device 1 of this embodiment, the drain tank 22 is integrally fixed to the blower 4 as a characteristic configuration. This structure prevents vibrations that occur when the blower 4 is driven. This structure will be described in detail below.

  As shown in FIG. 2, the drain tank 22 is a box composed of a top surface portion 32, a bottom surface portion 33, a left side surface portion 34, a right side surface portion 35, a front surface portion 36, and a back surface portion 37. More specifically, as for the left side surface part 34, the upper side part protrudes outside, and the lower side part is depressed inside, and the lower side part of the right side part 35 protrudes outside. That is, it can be said that the drain tank 22 is a box extending in an oblique direction.

  The top surface portion 32 of the drain tank 22 is formed with an electrode mounting portion 39 for mounting a plurality of round bar electrodes (not shown). The plurality of electrodes attached to the electrode attachment portion 39 function as a water level detection means for detecting the water level of the drain tank 22.

  In the bottom 33 of the drain tank 22, a drain pipe 42, which is a tubular body that protrudes substantially vertically downward, is formed at a position close to one side (the left side 34) and on the front side. ing. The drain pipe 42 is a portion serving as an auxiliary outlet for draining water, and is normally used by being closed with a drain plug. And it is used to discharge the drain (liquid) in the drain tank to the outside under a specific situation where it is necessary to forcibly drain water, such as when performing maintenance.

  The left side surface portion 34 of the drain tank 22 is formed with an air vent tube 43 that is a tube body projecting outward substantially in the horizontal direction at a portion near the upper end and from the front end. The air vent pipe 43 discharges air in the internal space of the drain tank 22 to the outside so that the pressure inside the drain tank 22 does not increase when the drain flows into the internal space of the drain tank 22. Use for.

  The right side surface portion 35 of the drain tank 22 is formed by a curved surface portion 46 positioned on the upper side and a standing wall portion 47 positioned on the lower side portion.

The curved surface portion 46 is a curved surface extending in a circular arc shape, and the lower end portion is located outside the upper end portion. That is, the curved surface portion 46 extends while gently curving outward and downward.
The curved surface portion 46 is formed with a drain introduction tube 50 which is a tube body projecting outward in a substantially horizontal direction at a portion near the upper end and from the front end. The drain introduction pipe 50 is a part for introducing drain into the internal space of the drain tank 22.

  The upright wall portion 47 is an upright, substantially rectangular flat plate-shaped portion, and the upper end portion is continuous with the curved surface portion 46 and the lower end portion is continuous with the bottom surface portion 33. A drain discharge pipe 51, which is a tubular body that protrudes substantially outward in the horizontal direction, is formed on the standing wall 47. The drain discharge pipe 51 is a portion for discharging drain from the internal space of the drain tank 22.

  Here, when attention is paid to the upper portion of the drain tank 22, it is a plate body extending over the top surface portion 32 and the curved surface portion 46, and is a fixing for fixing the drain tank 22 to an external member such as the blower 4 (see FIG. 1). A plate portion 54 is formed.

  The fixed plate portion 54 intersects the top surface portion 32 and the curved surface portion 46 substantially perpendicularly, and includes a reinforcing portion 55 located above the top surface portion 32 and a main body portion 56 located outside the top surface portion 32 and the curved surface portion 46. And.

  The reinforcing portion 55 is formed at the top of the top surface portion 32 and extends in a substantially rectangular shape in cross section. More specifically, the reinforcing portion 55 is a portion that linearly extends outward from the edge of the electrode mounting portion 39.

The main body portion 56 is a vertical plate-like portion in which the longitudinal direction of the drain tank 22 is the member thickness direction. The main body 56 projects outward and has a substantially horizontally long rectangular shape when viewed from the front. The upper portion of the main body portion 56 is integrated with the reinforcing portion 55, and the lower portion is integrated with the curved surface portion 46.
Further, a notch groove 57 extending from the protruding end toward the base end side is formed in the vicinity of the center of the main body portion 56 in the vertical direction. This notch groove 57 extends linearly along the horizontal direction (the direction from the right side to the left side), and specifically, slightly from the center of the horizontal direction (left and right direction) from the protruding end of the main body 56. It extends to the part from the base end side. Further, the distal end portion in the extending direction of the notch groove 57, in other words, the portion of the notch groove 57 from the most proximal side of the main body portion 56 is rounded and convex toward the inside.

  In this embodiment, as shown in FIG. 1 and FIG. 3, the back surface of the fixing plate portion 54 of the drain tank 22 is brought into contact with the front surface of the blower 4, and fastening elements such as screws, screws, bolts, and scissors are used. The drain tank 22 and the blower 4 are fixed together.

  Here, the curved portion 46 of the drain tank 22 and a part of the side surface 59 of the blower 4 have the same or substantially the same curvature. Therefore, the curved surface portion 46 that is a part of one side surface (right side surface portion 35) of the drain tank 22 and the one side surface 59 of the blower 4 are in close contact with each other. In other words, the drain tank 22 and the blower 4 are integrally fixed in a state where they are in surface contact with each other over a wide range with no gaps (or with some gaps allowing no gaps). Thus, vibration generated when the blower 4 is driven can be reliably transmitted to the liquid (neutralized drain) stored in the drain tank 22.

  Further, as shown in FIG. 1, the drain tank 22 is disposed in the housing 2 in a state where the bottom surface portion 33 (see FIG. 2) of the drain tank 22 and the bottom plate portion 11 of the housing 2 are in close contact (or substantially in close contact). It is fixed to. More specifically, the drain pipe 42 of the drain tank 22 is inserted into a through hole (not shown) formed in the bottom plate portion 11, and the bottom surface 33 of the drain tank 22 and the bottom plate portion 11 of the housing 2 are The drain tank 22 is integrally fixed to the housing 2 in a state where the upper surface is in contact with the housing 2. Thus, by fixing the drain tank 22 to the housing | casing 2 integrally, the suppression effect of the vibration which the air blower 4 emits can be heightened.

In the above-described embodiment, the heat source apparatus 1 in which the neutralizer 21 and the drain tank 22 are separately provided has been described, but the present invention is not limited to this. For example, a neutralizer in which a neutralizer and a drain tank are integrally formed may be provided in the drain discharge system, and the neutralizer may be fixed to a device that generates vibration such as the blower 4. That is, the heat source unit has a built-in neutralizer (neutralizer) that performs neutralization of drain water and storage of neutralized drain water in one container, and a device that generates vibration is fixed to the neutralizer. May be. In this case, since the particulate neutralizing agent (calcium carbonate or the like) incorporated in the neutralizer is also vibrated, there is an advantage that the neutralizing agent can be arranged evenly in the neutralizer. More specifically, in the neutralizer, the internal space is usually divided into a plurality of chambers by partitions, and a predetermined chamber is filled with many granular neutralizers. This neutralizing agent is distributed evenly throughout the room at the start of operation, but by continuing the operation of the heat source unit, the neutralizing agent is biased to one side of the room due to the flow of drain flowing through the room. It is thought that it will be done. If the neutralizing agent is biased and arranged on one side of the room in this way, there is a possibility that problems such as clogging of the neutralizing agent into holes or the like for circulating the drain may occur. However, when vibration is applied to the neutralizer, the vibration causes the neutralizer to move. That is, since the neutralizing agent moves from a portion where the neutralizing agent is arranged unevenly to a portion where no (or almost) neutralizing agent is arranged, the neutralizing agent is evenly distributed in the room. Therefore, problems such as clogging of the neutralizing agent do not occur.
In addition, it is preferable that the neutralizing agent is evenly distributed in the room because the neutralizing agent is consumed uniformly in all parts of the room.

  Moreover, in the heat source apparatus 1 which provided the neutralizer and the drain tank separately, you may fix the apparatus which emits a vibration to a neutralizer instead of a drain tank. Furthermore, you may fix both a neutralizer and a drain tank to the apparatus which emits a vibration. That is, the member for storing the liquid may be fixed to the device that generates vibration, and there may be a plurality of members for storing the liquid fixed to the device that generates vibration.

  In addition, a heating circulation circuit in which hot water or a heat medium circulates between an external heating device such as a fan convector and a primary heat exchanger 5 and / or a secondary heat exchanger 6 (hereinafter also simply referred to as a heat exchanger). When the present invention is adopted in the formed heat source machine, an expansion tank provided in the heating circulation circuit may be fixed to a device that generates vibration. That is, the heat source apparatus of the present invention forms a pipe for flowing hot water or a heat medium from the heat exchanger to an external heating device, and a pipe for flowing hot water or a heat medium from the external heating device to the heat exchanger. And the heat source machine which provided the heating circulation pump for forming a circulation flow in the appropriate part of these piping, and the expansion tank for adjusting the pressure in piping formed the heating circulation circuit may be sufficient. And you may suppress the vibration which an apparatus emits by fixing the expansion tank provided in the heating circulation circuit to the apparatus which emits a vibration.

  The combustion unit 3 may burn a liquid fuel such as kerosene with a burner, and may be provided with a fuel supply pump for supplying liquid fuel to the burner side. In this case, a member for storing the liquid may be fixed to the fuel supply pump to suppress vibration generated when the fuel supply pump is driven.

  In addition, when the present invention is applied to a heat source machine that forms a bathtub circulation circuit that circulates hot water between the bathtub and the heat exchanger to replenish the hot water in the bathtub, it is necessary to form a circulation flow of the bathtub circulation circuit. The present invention may be adopted to suppress vibration of the bath circulation pump. That is, a member for storing a liquid such as a drain tank may be fixed to the bath circulation pump to suppress vibration generated when the bath circulation pump is driven.

Further, in the present invention, in order to suppress vibrations of various pumps such as the drain discharge pump 24, the heating circulation pump, the fuel supply pump, the bath circulation pump, etc., a member for storing the liquid may be fixed thereto. Good. That is, the vibrating body, which is a device that suppresses vibration, is not limited to the blower 4 and may be another device. Further, for example, a member for storing liquid such as a drain tank may be fixed to a plurality of vibrating bodies such as the blower 4 and any one of the pumps.
That is, one liquid storage member may be fixed to one vibrating body, or a plurality of liquid storage members may be fixed. Further, one liquid storage member may be fixed to the plurality of vibrating bodies, or the plurality of vibrating bodies and the plurality of liquid storage members may be fixed in a lump shape.

  In the above-described embodiment, the blower 4 and the drain tank 22 are directly fixed. However, the present invention is not limited to this and may be integrally attached via a fixing member such as a metal fitting.

  In the above-described embodiment, the example in which the vibration body such as the blower 4 is fixed to the liquid storage member such as the drain tank 22 and the vibration generated when the vibration body is driven has been described. If it does in this way, while the liquid stored in the liquid storage member and the liquid storage member acts as a weight with respect to a vibrating body, the liquid stored in the liquid storage member absorbs the vibration transmitted from the vibrating body. Can suppress the vibration generated by. Moreover, according to such a structure, the freezing of the liquid stored by the liquid storage member can also be prevented. That is, since vibration is transmitted to the liquid stored in the liquid storage member, there is an effect that the liquid surface of the liquid stored in the liquid storage member shakes and becomes difficult to freeze.

Therefore, the heat source apparatus of the present invention is provided with temperature detecting means (such as a thermistor) capable of detecting the internal temperature of the housing 2, and the internal temperature becomes a predetermined temperature or less during non-combustion when the combustion operation is not performed in the combustion unit 3. It is good also as a structure which drives the air blower 4 continuously or intermittently on condition.
That is, even if the vibrating body is not normally driven, the vibrating body is driven to prevent the liquid (drain) stored in the liquid storage member (drain tank 22) from freezing. Also good. Similarly, various pumps and the like may be driven on the condition that the internal temperature of the housing 2 is equal to or lower than a predetermined temperature. For example, in a situation where a circulation flow is not required in a bathtub circulation circuit, a heating circulation circuit, or the like, that is, a situation where a bath is not replenished or a heating device is not used, heating circulation is performed for a predetermined time. It is good also as a structure which drives a pump and a bath circulation pump. By doing in this way, freezing of the liquid stored by the liquid storage member can be prevented more reliably.
