水熱交換器115は、周囲を断熱材119に覆われている。水熱交換器115と断熱材119とは、略直方体形状の筐体120に覆われ、ファン117の下方に配置されるとともに、外装体118を構成する下板118aの上に配置されて固定されている。 The water heat exchanger 115 is covered with a heat insulating material 119. The water heat exchanger 115 and the heat insulating material 119 are covered with a substantially rectangular parallelepiped casing 120 and are disposed below the fan 117 and are disposed and fixed on the lower plate 118a constituting the exterior body 118. ing.
ファン117は、ファンモータ119によって駆動される。ファンモータ119は、支柱121に固定されている。支柱121は、上方で蒸発器118と前板118cとを接続する梁110に接続され、下方で筐体120の上面に接続されて、固定される。 The fan 117 is driven by a fan motor 119. The fan motor 119 is fixed to the support 121. The column 121 is connected to the beam 110 that connects the evaporator 118 and the front plate 118c at the upper side, and is connected to the upper surface of the housing 120 at the lower side and fixed.
しかしながら、前記従来の構成では、ファンモータが固定される支柱は、水熱交換器を覆う収容部の上面に固定されている。よって、温水生成装置の運転中に、ファンモータによって駆動されるファンの振動が筐体の上面へと伝播し、特にファンの上下動による振動が収容部の上面へと伝播した場合には、騒音が増大してしまうという課題を有していた。 However, in the conventional configuration, the support column to which the fan motor is fixed is fixed to the upper surface of the housing portion that covers the water heat exchanger. Therefore, during the operation of the hot water generator, the vibration of the fan driven by the fan motor propagates to the upper surface of the housing, and particularly when the vibration due to the vertical movement of the fan propagates to the upper surface of the housing part, Had the problem of increasing.
本発明は、上記従来の課題を解決するためのもので、運転時の騒音が低減した温水生成装置を提供することを目的とする。 The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide a hot water generator that reduces noise during operation.
前記従来の課題を解決するために、本発明の温水生成装置は、圧縮機、冷媒と水との間で熱交換を行う水熱交換器、減圧器、蒸発器が冷媒配管で環状に接続された冷媒回路と、前記水熱交換器の周囲を覆う断熱材と、前記断熱材の少なくとも上面および側面を覆う筐体と、前記蒸発器に送風するファンと、前記ファンを回転させるファンモータと、前記ファンモータが固定される支柱と、前記断熱材および前記蒸発器が配置される底板と、を備え、前記支柱は、前記筐体と前記蒸発器との間で、前記底板に接続され、前記水熱交換器は前記蒸発器の風下側に配置されており、前記支柱は、前記ファンモータよりも鉛直下方側において、下方よりも上方のほうが前記支柱と前記蒸発器との間の距離が長くなるように構成された傾斜部を有するとともに、前記傾斜部の前記筐体側と前記筐体の側面とが、弾性を有する接続部材にて離間して接続されていることを特徴とする。 In order to solve the above-mentioned conventional problems, the hot water generator of the present invention includes a compressor, a water heat exchanger that exchanges heat between the refrigerant and water, a decompressor, and an evaporator connected in an annular shape through a refrigerant pipe. A refrigerant circuit, a heat insulating material that covers the periphery of the water heat exchanger, a housing that covers at least an upper surface and a side surface of the heat insulating material, a fan that blows air to the evaporator, a fan motor that rotates the fan, wherein comprising a strut fan motor is fixed, a bottom plate, wherein the heat insulating material and the evaporator is disposed, the said strut between said evaporator and said housing, connected to the bottom plate, the The water heat exchanger is disposed on the leeward side of the evaporator, and the column is vertically lower than the fan motor, and the distance between the column and the evaporator is longer in the upper side than in the lower side. Having an inclined part configured to be Moni, the side surface of the housing side and the housing of the inclined portion, characterized in that it is connected at a distance by a connecting member having elasticity.
これにより、支柱が水熱交換器を収容する筐体の上面に接続されないので、ファンの回転によって生じる振動が筐体の上面へと伝播することを抑制することができる。 Thereby, since a support | pillar is not connected to the upper surface of the housing | casing which accommodates a water heat exchanger, it can suppress that the vibration which arises by rotation of a fan propagates to the upper surface of a housing | casing.
本発明によれば、運転時の騒音が低減した温水生成装置を提供することができる。 According to the present invention, it is possible to provide a hot water generator with reduced noise during operation.
第1の発明は、圧縮機、冷媒と水との間で熱交換を行う水熱交換器、減圧器、蒸発器が冷媒配管で環状に接続された冷媒回路と、前記水熱交換器の周囲を覆う断熱材と、前記断熱材の少なくとも上面および側面を覆う筐体と、前記蒸発器に送風するファンと、前記ファンを回転させるファンモータと、前記ファンモータが固定される支柱と、前記断熱材および前記蒸発器が配置される底板と、を備え、前記支柱は、前記筐体と前記蒸発器との間で、前記底板に接続され、前記水熱交換器は前記蒸発器の風下側に配置されており、前記支柱は、前記ファンモータよりも鉛直下方側において、下方よりも上方のほうが前記支柱と前記蒸発器との間の距離が長くなるように構成された傾斜部を有するとともに、前記傾斜部の前記筐体側と前記筐体の側面とが、弾性を有する接続部材にて離間して接続されていることを特徴とする温水生成装置である。 A first invention includes a compressor, a water heat exchanger for exchanging heat between the refrigerant and water, a decompressor, a refrigerant circuit in which an evaporator is annularly connected by a refrigerant pipe, and the periphery of the water heat exchanger A heat insulating material that covers at least the upper surface and side surfaces of the heat insulating material, a fan that blows air to the evaporator, a fan motor that rotates the fan, a support post to which the fan motor is fixed, and the heat insulating material Material and a bottom plate on which the evaporator is disposed, the strut is connected to the bottom plate between the housing and the evaporator, and the water heat exchanger is on the leeward side of the evaporator The support column has an inclined portion configured such that the distance between the support column and the evaporator is longer on the upper side than the lower side on the vertically lower side than the fan motor. The housing side of the inclined portion and the housing Surface and is a hot water generation apparatus characterized by being connected spaced apart at a connection member having elasticity.
これにより、支柱が水熱交換器を収容する筐体の上面に接続されないので、ファンの振動が筐体の上面へと伝播することを抑制することができる。 Thereby, since a support | pillar is not connected to the upper surface of the housing | casing which accommodates a water heat exchanger, it can suppress that a vibration of a fan propagates to the upper surface of a housing | casing.
また、支柱は、外装体の底板に固定されるので、振動の発振源であるファンモータおよびファンを強固に支えて固定することができ、騒音を低減させることができる。 In addition, since the support column is fixed to the bottom plate of the exterior body, the fan motor and the fan, which are vibration oscillation sources, can be firmly supported and fixed, and noise can be reduced.
なお、水熱交換器の筐体の上面は、支柱との接続がなくなったことで、ファンモータおよびファンの荷重がかからなくなり、振動の伝播も抑制される。 The upper surface of the housing of the water heat exchanger is not connected to the support column, so that the fan motor and the fan are not loaded, and vibration propagation is also suppressed.
よって、筐体に使用する鋼板材料の薄肉化ができるようになるので、筐体の軽量化を実現できる。 Therefore, since the steel plate material used for the housing can be thinned, the weight of the housing can be reduced .
また、これにより、支柱を外装体の底板に固定しても、支柱と蒸発器との間に一定の距離を確保することができる。よって、蒸発器と支柱とを近接させずに、送風室の内部での通風抵抗の増加を抑制するので、騒音が低減し、冷凍サイクルの効率を向上させることができる。 Moreover, even if it fixes a support | pillar to the bottom plate of an exterior body by this, a fixed distance can be ensured between a support | pillar and an evaporator. Therefore, since an increase in the ventilation resistance inside the air blowing chamber is suppressed without bringing the evaporator and the support close to each other, noise can be reduced and the efficiency of the refrigeration cycle can be improved.
さらに、冷凍サイクルの効率が向上することで、水熱交換器および蒸発器の容量を削減して小型化することが可能となり、機器の軽量化を図ることができる。 Furthermore, by improving the efficiency of the refrigeration cycle, the capacity of the water heat exchanger and the evaporator can be reduced and the size can be reduced, and the weight of the device can be reduced .
また、これにより、支柱と水熱交換器を覆う筐体との間に弾性を有する接続部材を設けて、部品同士の互いの振動による干渉、および、接触の発生を防止するので、騒音の発生を抑制し、低騒音の温水生成装置を実現することができる。 In addition, since a connecting member having elasticity is provided between the support column and the casing that covers the water heat exchanger, interference due to mutual vibration between components and generation of contact are prevented. And a low-noise hot water generator can be realized.
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって、本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

図1に示すように、本実施の形態における温水生成装置は、外装体1を備える。また、図1〜図3に示すように、外装体1は、温水生成装置の内部から空気が流出するように構
成された前板1a、右側板1b、左側板1c、底板1d、上板1eから構成されている。右側板1bには、生成された温水が流出する流出ポート11と、温水生成装置よって加熱される水が供給される流入ポート12とを覆うカバー1fが設けられている。前板1aは、ベルマウス形状のオリフィス31を有する。これにより、温水生成装置から空気が流出する吹出口32が形成される。
As shown in FIG. 1, the hot water generator in the present embodiment includes an exterior body 1. As shown in FIGS. 1 to 3, the exterior body 1 includes a front plate 1a, a right side plate 1b, a left side plate 1c, a bottom plate 1d, and an upper plate 1e that are configured so that air flows out from the inside of the hot water generator. It is composed of The right side plate 1b is provided with a cover 1f that covers an outflow port 11 through which the generated hot water flows out and an inflow port 12 through which water heated by the hot water generator is supplied. The front plate 1 a has a bell mouth shaped orifice 31. Thereby, the blower outlet 32 from which air flows out from a warm water production | generation apparatus is formed.
なお、図3(a)は、上板1eのうち、図中の真ん中の部分を取り除くことで、温水生成装置の内部構造を示している。また、図3(b)は、前板1aのうち、図中の右上の部分以外を取り除くことで、温水生成装置の内部構造を示している。なお、図3(b)は、ファン33を取り外した上体の内部構造を示している。 In addition, Fig.3 (a) has shown the internal structure of a warm water production | generation apparatus by removing the middle part in a figure among the upper boards 1e. Moreover, FIG.3 (b) has shown the internal structure of a warm water production | generation apparatus by removing except the upper right part in the figure among the front plates 1a. FIG. 3B shows the internal structure of the upper body from which the fan 33 is removed.
なお、温水生成装置において、前板1aと反対側の背面は、底板1dの上に配置された蒸発器24によって覆われている。なお、左側板1cは、例えば、蒸発器24によって上板1eを固定できるように構成されている場合には、なくてもよい。 In the hot water generator, the back surface opposite to the front plate 1a is covered by an evaporator 24 disposed on the bottom plate 1d. Note that the left side plate 1c may be omitted if the upper plate 1e can be fixed by the evaporator 24, for example.
温水生成装置は、冷凍サイクルを構成する冷媒回路を備えている。冷媒回路は、冷媒を圧縮する圧縮機21、冷媒と水との間で熱交換を行う水熱交換器22、冷媒を膨張させる膨張弁(減圧器)23、冷媒と空気との間で熱交換を行う蒸発器24が冷媒配管で環状に接続されて構成されている。圧縮機21と膨張弁23とは、制御部25によって制御される。温水生成時には、制御部25は、圧縮機21および膨張弁23を制御することで、水熱交換器22に高温高圧のガス冷媒を流入させる。水熱交換器22において、ガス冷媒が水に放熱することで温水が生成される。 The hot water generator includes a refrigerant circuit that constitutes a refrigeration cycle. The refrigerant circuit includes a compressor 21 that compresses the refrigerant, a water heat exchanger 22 that exchanges heat between the refrigerant and water, an expansion valve (decompressor) 23 that expands the refrigerant, and heat exchange between the refrigerant and air. The evaporator 24 is configured to be connected annularly by a refrigerant pipe. The compressor 21 and the expansion valve 23 are controlled by the control unit 25. At the time of generating hot water, the control unit 25 controls the compressor 21 and the expansion valve 23 to cause the high-temperature and high-pressure gas refrigerant to flow into the water heat exchanger 22. In the water heat exchanger 22, hot water is generated as the gas refrigerant radiates heat to the water.
水熱交換器22は、水が流れる水管の内部に冷媒が流れる冷媒管が収容された二重管式の熱交換器である。この二重管をコイル状に巻き回し、略直方体形状に成型している。水熱交換器22の周囲は、断熱材41によって覆われている。これにより、水熱交換器22からの放熱ロスが低減される。断熱材41は、発泡樹脂材料で構成されている。さらに、断熱材41の周囲のうち、上面および側面は、耐食処理を施した金属で構成された筐体42によって覆われている。これにより、火、紫外線、雨水、オゾンなどによる断熱材41の劣化を抑制して、温水を生成するときの熱交換性能の低下を防止している。なお、断熱材の上面とは、断熱材41の上板1e側の面をいい、側面とは、断熱材41において、上板1e側と底板1d側以外の面をいうものである。 The water heat exchanger 22 is a double-tube heat exchanger in which a refrigerant pipe through which a refrigerant flows is accommodated in a water pipe through which water flows. This double tube is wound into a coil shape and molded into a substantially rectangular parallelepiped shape. The periphery of the water heat exchanger 22 is covered with a heat insulating material 41. Thereby, the heat dissipation loss from the water heat exchanger 22 is reduced. The heat insulating material 41 is made of a foamed resin material. Further, the upper surface and side surfaces of the periphery of the heat insulating material 41 are covered with a casing 42 made of a metal subjected to corrosion resistance treatment. Thereby, deterioration of the heat insulating material 41 by fire, ultraviolet rays, rainwater, ozone, etc. is suppressed, and the fall of the heat exchange performance when producing | generating warm water is prevented. The upper surface of the heat insulating material refers to the surface on the upper plate 1e side of the heat insulating material 41, and the side surface refers to the surface of the heat insulating material 41 other than the upper plate 1e side and the bottom plate 1d side.
図3に示すように、温水生成装置の内部は、仕切板90によって、送風室91と機械室92とに分離される。 As shown in FIG. 3, the interior of the hot water generator is separated into a blower chamber 91 and a machine chamber 92 by a partition plate 90.
機械室92には、圧縮機21、膨張弁23および冷媒回路を構成する冷媒配管と、水熱交換器22と流出ポート11および流入ポート12とを接続する水配管が配置されている。水熱交換器22と流出ポート11および流入ポート12とを接続する水配管は、圧縮機21よりも前板1a側に配置される。また、水熱交換器22の冷媒管は、圧縮機21よりも前板1a側で冷媒回路に接続される。これにより、水熱交換器22のメンテナンスが必要となった場合、前板1aを取り外すのみで水熱交換器22およびその周辺の冷媒配管と水配管とが露出するので、作業性が向上する。 In the machine room 92, refrigerant pipes constituting the compressor 21, the expansion valve 23 and the refrigerant circuit, and water pipes connecting the water heat exchanger 22, the outflow port 11 and the inflow port 12 are arranged. A water pipe connecting the water heat exchanger 22 to the outflow port 11 and the inflow port 12 is disposed on the front plate 1 a side with respect to the compressor 21. Further, the refrigerant pipe of the water heat exchanger 22 is connected to the refrigerant circuit on the front plate 1 a side with respect to the compressor 21. Thereby, when the maintenance of the water heat exchanger 22 becomes necessary, since the water heat exchanger 22 and the refrigerant piping and the water piping in the vicinity thereof are exposed only by removing the front plate 1a, workability is improved.
送風室91には、断熱材41で周囲を覆われた水熱交換器22、蒸発器24、蒸発器24に空気を送風するためのファン33、ファン33を回転させるファンモータ34が配設されている。断熱材41で覆われた水熱交換器22は、底板1dの上に配置されている。前述の通り、断熱材41の上面および側面は、筐体42によって覆われている。よって、断熱材41の周囲は、筐体42と底板1dとによって周囲を覆われることとなる。これにより、断熱材41が、火、紫外線、雨水、オゾンなどにさらされることを抑制して、断熱
材の劣化を抑制することができる。
The blower chamber 91 is provided with a water heat exchanger 22 whose periphery is covered with a heat insulating material 41, an evaporator 24, a fan 33 for blowing air to the evaporator 24, and a fan motor 34 for rotating the fan 33. ing. The water heat exchanger 22 covered with the heat insulating material 41 is disposed on the bottom plate 1d. As described above, the upper surface and side surfaces of the heat insulating material 41 are covered with the housing 42. Therefore, the periphery of the heat insulating material 41 is covered by the casing 42 and the bottom plate 1d. Thereby, it can suppress that the heat insulating material 41 is exposed to a fire, an ultraviolet-ray, rainwater, ozone, etc., and can suppress deterioration of a heat insulating material.
なお、蒸発器24の周辺は、温水生成装置の運転中に、外気温度より5〜8K程度低い温度となる。一方、蒸発器24よりも、送風室91を流れる空気の流れ方向に対して風下側に配置され、蒸発器24と近接する水熱交換器22は、温水生成装置の運転中に、最高で90℃程度の高温となる。すなわち、外気温度が低く、高温水を生成する冬季には、蒸発器24の周辺と水熱交換器22との温度差が最大で100K程度となる。 In addition, the periphery of the evaporator 24 becomes a temperature about 5-8K lower than the outside air temperature during the operation of the hot water generator. On the other hand, the water heat exchanger 22 which is disposed on the leeward side with respect to the flow direction of the air flowing through the air blowing chamber 91 relative to the evaporator 24 and is close to the evaporator 24 is 90 at maximum during the operation of the hot water generator. It becomes a high temperature of about ℃. That is, in winter when the outside air temperature is low and high temperature water is generated, the temperature difference between the periphery of the evaporator 24 and the water heat exchanger 22 is about 100K at the maximum.
よって、特に、水熱交換器22の周囲を覆う断熱材41の風上側の側面は、筐体42と底板1dとを密着させて、水熱交換器22からの放熱ロスを低減するようにしている。このとき、筐体42と底板1dとを、筐体42が底板1dよりも外方に来るように密着させることが好ましい。これにより、例えば、送風室91に雨水などが浸入しても、断熱材41に水が触れることを防止して、断熱材41の劣化を防ぐことができる。 Therefore, in particular, the side surface on the windward side of the heat insulating material 41 covering the periphery of the water heat exchanger 22 is configured so that the casing 42 and the bottom plate 1d are brought into close contact with each other so as to reduce the heat radiation loss from the water heat exchanger 22. Yes. At this time, it is preferable that the housing 42 and the bottom plate 1d are brought into close contact with each other so that the housing 42 comes outside the bottom plate 1d. Thereby, for example, even if rainwater or the like enters the blower chamber 91, it is possible to prevent water from touching the heat insulating material 41 and to prevent deterioration of the heat insulating material 41.
ファン33は、ファンモータ34を介して、支柱35に固定されている。なお、ファン33の中心軸と、オリフィス31の中心軸とは、ほぼ同軸となるように配置されている。 The fan 33 is fixed to the support 35 via a fan motor 34. The central axis of the fan 33 and the central axis of the orifice 31 are arranged so as to be substantially coaxial.
支柱35の下方は、例えば、ネジなどの締結部材によって、外装体1を構成する底板1dに接続されている。また、支柱35の上方は、例えば、ネジなどの締結部材によって、蒸発器24と前板1aとに固定された固定板36に接続されている。固定板36は、蒸発器24を構成するフィンに嵌め込まれる突起36aと、前板1aと締結される固定部36bとを有している。なお、固定板36と前板1aとは、例えばネジによって、固定される。 The lower side of the column 35 is connected to the bottom plate 1d constituting the exterior body 1 by a fastening member such as a screw, for example. Moreover, the upper part of the support | pillar 35 is connected to the fixed board 36 fixed to the evaporator 24 and the front board 1a by fastening members, such as a screw, for example. The fixed plate 36 has a protrusion 36a that is fitted into a fin constituting the evaporator 24, and a fixed portion 36b that is fastened to the front plate 1a. The fixed plate 36 and the front plate 1a are fixed by screws, for example.
このように、支柱35が、底板1dと、固定板36とに接続され、外装体1と一体となって強固に固定されるので、温水生成装置の運転中にファン33が回転することによって生じる振動を抑制して、騒音を低減させることができる。 As described above, the support column 35 is connected to the bottom plate 1d and the fixed plate 36, and is firmly fixed integrally with the exterior body 1, so that the fan 33 rotates during operation of the hot water generator. Vibration can be suppressed and noise can be reduced.
なお、支柱35と底板1dとの接続箇所は、蒸発器24の表面に付着した水分を温水生成装置の外部へと排出する排水路37よりも鉛直上方に設けられることが好ましい。これにより、支柱35と底板1dとの接続箇所に水分が付着して腐食することを防止することができる。 In addition, it is preferable that the connection location of the support | pillar 35 and the baseplate 1d is provided vertically upwards rather than the drainage channel 37 which discharges | emits the water | moisture content adhering to the surface of the evaporator 24 to the exterior of a warm water production | generation apparatus. Thereby, it can prevent that a water | moisture content adheres to the connection location of the support | pillar 35 and the baseplate 1d, and corrodes.
支柱35は、図3に示すように、送風室91内に流れる空気の通風抵抗を抑制するために、開口部35aを有している。また、支柱35は、図4に示すように、板状の金属の端部が、送風室91の内部を流れる空気の流れ方向に対して風下側に折曲げられて形成されている。これにより、支柱35によって生じる、送風室91の内部を流れる空気の通風抵抗を抑制することができるとともに、支柱35の強度を増加させることができる。 As shown in FIG. 3, the support column 35 has an opening 35 a in order to suppress the ventilation resistance of the air flowing into the blower chamber 91. Further, as shown in FIG. 4, the support column 35 is formed by bending an end portion of a plate-like metal toward the leeward side with respect to the flow direction of the air flowing inside the blower chamber 91. Thereby, while being able to suppress the ventilation resistance of the air which flows through the inside of the ventilation chamber 91 which arises with the support | pillar 35, the intensity | strength of the support | pillar 35 can be increased.
さらに、支柱35は、図4に示すように、ファンモータ34の固定箇所よりも鉛直下側において、下方よりも上方のほうが、支柱35と蒸発器24の風下側のフィンとの間の距離Lが長くなるように構成された傾斜部35bを有している。 Furthermore, as shown in FIG. 4, the column 35 is vertically lower than the fixed position of the fan motor 34, and the distance L between the column 35 and the fin on the leeward side of the evaporator 24 is higher than the lower side. It has the inclination part 35b comprised so that may become long.
傾斜部35bによって、図4に示すように、支柱35を、筐体42と蒸発器24との間で底板1dに接続しながら、支柱35と蒸発器24との間の距離を一定以上に確保することができる。よって、支柱35による送風室91内の通風抵抗を低減して、蒸発器24の熱交換性能を向上させることができる。傾斜部35bは、下方から上方に向かって、蒸発器24から離反するように形成されるので、特に、蒸発器24の下方における、筐体42と蒸発器24との間の通風抵抗を低減して、蒸発器24の熱交換性能を向上させる。 As shown in FIG. 4, the inclined portion 35 b secures a distance between the support column 35 and the evaporator 24 to a certain level or more while connecting the support column 35 to the bottom plate 1 d between the casing 42 and the evaporator 24. can do. Therefore, the ventilation resistance in the ventilation chamber 91 by the support | pillar 35 can be reduced, and the heat exchange performance of the evaporator 24 can be improved. The inclined portion 35b is formed so as to be separated from the evaporator 24 from the lower side to the upper side. Therefore, in particular, the ventilation resistance between the housing 42 and the evaporator 24 under the evaporator 24 is reduced. Thus, the heat exchange performance of the evaporator 24 is improved.
図5は、接続部材43を、温水生成装置の背面側すなわち蒸発器24側から見た際の拡大図である。 FIG. 5 is an enlarged view of the connection member 43 as viewed from the back side of the hot water generator, that is, from the evaporator 24 side.
支柱35と筐体42の蒸発器24側の側面とは、弾性を有する接続部材43によって接続されている。具体的には、支柱35の開口部35aを形成し、水平方向に形成された補強部35dと筐体42の蒸発器24側の側面とが、接続部材43によって接続されている。これにより、支柱35と筐体42とを近接して配置しながら、部品同士の互いの振動および接触音の発生を防止して、温水生成装置のコンパクト化と低騒音化を実現することができる。ここで、接続部材43は、弾性を有するとともに耐食性、耐候性を有する樹脂で構成されていることが好ましい。 The column 35 and the side surface of the housing 42 on the evaporator 24 side are connected by a connecting member 43 having elasticity. Specifically, the opening 35 a of the support column 35 is formed, and the reinforcing portion 35 d formed in the horizontal direction and the side surface on the evaporator 24 side of the housing 42 are connected by the connection member 43. Thereby, while the support | pillar 35 and the housing | casing 42 are arrange | positioned closely, generation | occurrence | production of the mutual vibration and contact sound of components can be prevented, and the hot water production | generation apparatus can be reduced in size and reduced in noise. . Here, it is preferable that the connection member 43 is made of a resin having elasticity and corrosion resistance and weather resistance.
接続部材43と筐体42とは、例えば、ネジなどの締結部材によって互いに接続されている。図5に示すように、接続部材43は、複数の大きさの水熱交換器22に対応するため、鉛直方向に並列に、複数のスリット43aを備えている。 The connection member 43 and the housing 42 are connected to each other by a fastening member such as a screw, for example. As shown in FIG. 5, the connection member 43 includes a plurality of slits 43 a in parallel in the vertical direction in order to correspond to a plurality of sizes of the hydrothermal exchanger 22.
また、支柱35は、鉛直方向に形成されたビード35cを有している。これにより、支柱35の強度が増加する。 Moreover, the support | pillar 35 has the bead 35c formed in the perpendicular direction. Thereby, the intensity | strength of the support | pillar 35 increases.
以上のように、ファン33およびファンモータ34が固定される支柱35が、筐体42の上面に接続されることがなく、外装体1の底板1dに固定されるので、振動の発振源であるファンモータ34およびファン33を強固に支えて固定することができ、騒音を低減させることができる。 As described above, the support column 35 to which the fan 33 and the fan motor 34 are fixed is not connected to the upper surface of the housing 42 and is fixed to the bottom plate 1d of the exterior body 1, and thus is a vibration oscillation source. The fan motor 34 and the fan 33 can be firmly supported and fixed, and noise can be reduced.
なお、水熱交換器22を覆う筐体42の上面は、支柱35との接続がなくなったことで、ファンモータ34およびファン33の荷重がかからなくなり、振動の伝播も抑制される。よって、筐体42に使用する鋼板材料の薄肉化ができるようになるので、筐体の軽量化を実現できる。 Note that the upper surface of the casing 42 covering the water heat exchanger 22 is not connected to the support column 35, so that the loads of the fan motor 34 and the fan 33 are not applied, and the propagation of vibration is also suppressed. Therefore, since the steel plate material used for the housing 42 can be thinned, the weight of the housing can be reduced.
また、支柱35は、ファンモータ34よりも鉛直下方側で、下方よりも上方のほうが、支柱35と蒸発器24との間の距離が長くなるように構成されている。これにより、支柱35を、筐体42と蒸発器24との間で底板1dに接続することでファン33の回転によって生じる騒音を低減しながら、支柱35と蒸発器24との間の距離を一定以上に確保することによって、送風室91内の通風抵抗を低減して、蒸発器24の熱交換性能を向上させることができる。 Moreover, the support | pillar 35 is comprised so that the distance between the support | pillar 35 and the evaporator 24 may become long in the vertically downward side rather than the fan motor 34, and upwards rather than the downward direction. Thereby, the distance between the support column 35 and the evaporator 24 is kept constant while reducing the noise generated by the rotation of the fan 33 by connecting the support column 35 to the bottom plate 1d between the casing 42 and the evaporator 24. By ensuring the above, the ventilation resistance in the ventilation chamber 91 can be reduced, and the heat exchange performance of the evaporator 24 can be improved.
さらに、弾性を有する接続部材43によって支柱35と水熱交換器22を覆う筐体42とを接続しているので、支柱35と筐体42とを近接して配置しながら、部品同士の互いの振動および接触音の発生を防止して、温水生成装置のコンパクト化と低騒音化を実現する。 Further, since the support column 35 and the casing 42 covering the water heat exchanger 22 are connected by the connecting member 43 having elasticity, the columns 35 and the casing 42 are arranged close to each other while the components are mutually connected. The generation of vibration and contact noise is prevented, and the hot water generator is made compact and low in noise.
以上のように、本発明の温水生成装置は、ファンの回転によって生じる振動および振動によって生じる騒音を抑制することができるので、家庭用、業務用に用いる温水生成装置に有用である。 As described above, the hot water generating device of the present invention can suppress vibrations caused by the rotation of the fan and noise generated by the vibrations, and thus is useful for hot water generating devices used for home use and business use.
