従来、ヒートポンプユニットと貯湯タンクユニットが分離した分離型のヒートポンプ式給湯機が開発されている。そして分離型のヒートポンプ式給湯機と同時に、設置スペースの狭小化を目的とし冷凍サイクルと給湯サイクルとを一つの筐体内に一体的に収納した一体型ヒートポンプ式給湯機が開発されている（例えば、特許文献１参照）。   Conventionally, a separation type heat pump type hot water heater in which a heat pump unit and a hot water storage tank unit are separated has been developed. In addition to the separate heat pump water heater, an integrated heat pump water heater has been developed in which a refrigeration cycle and a hot water cycle are integrally housed in a single housing for the purpose of reducing the installation space (for example, Patent Document 1).

図４は、従来の冷凍サイクルと給湯サイクルとを一体的に収納した一体型ヒートポンプ式給湯機の構成図である。図４において、従来の一体型ヒートポンプ式給湯機は、筐体の外郭底部を形成する第１の基板１０１の上に、圧縮機１０２、水冷媒熱交換器１０６、循環ポンプ１０４が配設され、筐体を左右に分割するように遮音板１０８が設けられている。そして遮音板１０８によって分割された一方側に貯湯タンク１０３を配設し、第１の基板１０１の上方に設けられた第２の基板１０７と、前記遮音板１０８とで区画され、前記貯湯タンク１０３が配設されている側と反対の側に蒸発器１１０と送風ファン１０９とが配設され、送風ファン１０９を第２の基板１０７に固定する固定金具によって、電装箱１１１が下方から支持されている。
特開２００５−１７２３８４号公報 FIG. 4 is a configuration diagram of an integrated heat pump type hot water heater that integrally stores a conventional refrigeration cycle and a hot water supply cycle. In FIG. 4, a conventional integrated heat pump type hot water heater is provided with a compressor 102, a water-refrigerant heat exchanger 106, and a circulation pump 104 on a first substrate 101 that forms the outer bottom of a casing. A sound insulating plate 108 is provided so as to divide the housing into left and right. A hot water storage tank 103 is disposed on one side divided by the sound insulating plate 108, and is partitioned by the second substrate 107 provided above the first substrate 101 and the sound insulating plate 108. The evaporator 110 and the blower fan 109 are disposed on the side opposite to the side where the blower fan 109 is disposed, and the electrical box 111 is supported from below by a fixing bracket that fixes the blower fan 109 to the second substrate 107. Yes.
