no. 1 Embodiment approach

[0055] figure 1 A schematic configuration diagram showing a first embodiment of the hot water supply device of the present invention. like figure 1 As shown, the hot water supply device has a heat pump unit 1 and a hot water storage unit 2 connected to the heat pump unit 1 .

[0056] The heat pump unit 1 has a compressor 11 , an expansion valve (decompression mechanism) 14 as an expansion portion, and an air heat exchanger (evaporator) 15 . Expansion valve 14 , air heat exchanger 15 , and compressor 11 are sequentially connected through refrigerant passage 16 . Regarding refrigerants, for example using CO 2 The refrigerant. A fan 17 and a motor 18 for driving the fan 17 are arranged to face the air heat exchanger 15 .

[0057] The hot water storage unit 2 has: a water heat exchanger 3, which is connected to the compressor 11 of the heat pump unit 1, and generates warm water through heat exchange; and a tank 4, which stores warm water. A water inlet flow path 5 a branched...

no. 2 Embodiment approach

[0074] Figure 4 The second embodiment of the hot water storage unit of the present invention is shown. in particular, Figure 4 A sectional view of a main part of the lower part of the hot water storage unit is shown. The difference from the above-mentioned first embodiment will be described. In this second embodiment, the shape of the heat insulating member is different, and a part of the heat insulating member constitutes a support portion for supporting the water heat exchanger. In addition, in this second embodiment, the same reference numerals as those of the above-mentioned first embodiment denote the same structures as those of the above-mentioned first embodiment, and thus description thereof will be omitted.

[0075] like Figure 4 As shown, the entire outer surface of the water heat exchanger 3 is covered with a heat insulating member 33 . The heat insulating member 33 is formed of substantially rectangular parallelepiped-shaped styrofoam, and is placed on the f...

Abstract

The invention provides a hot water storage unit and a hot water supplying device. Even when water is contained in a bottom frame, corrosion of a water heating exchanger can be prevented. The hot water storage unit comprises a water heating exchanger (3), a pot body (4), a bottom frame (23) and a support part (31), wherein the bottom frame (23) is provided with a vertical part (23a) storing water; the support part (31) is placed on in a position where the water heating exchanger (3) is placed close the upper side of the vertical part compared with the bottom frame (23); and the water heating exchanger (3) is supported by the support part.

Description

technical field [0001] The invention relates to a hot water storage unit and a hot water supply device. Background technique [0002] In the past, some hot water supply devices have been provided with a heat source unit having a water heat exchanger (Japanese Patent Laid-Open No. 2011-2172 (Patent Document 1)). In this hot water supply device, the water heat exchanger is provided on the bottom frame of the heat source unit. The bottom frame has a rising portion on the periphery of the bottom frame, and the water flowing into the bottom frame is stored in the bottom frame by the rising portion. [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese Unexamined Patent Publication No. 2011-2172 [0006] However, the water heat exchanger is covered with a heat insulating member having a hole for draining leaked water and dew condensation water, and when water is stored in the bottom frame, water enters through the hole. Also, since...
