  The wiring of the hot water storage type hot water heater is built-in to avoid interference with the metal fastening parts and sheet metal parts used in the pipe connection parts to protect them from the edges of the pipe connection parts and the dew condensation water generated on the pipe parts. For example, it is fixed by tape to the tank insulation covering the hot water storage tank. Also, dew condensation water travels through the wiring and piping and reaches the wiring connection part such as a connector that connects the wirings, and reaches the wiring connection part so that the wiring connection part does not have an influence of insulation failure or corrosion. The wiring was slackened in the direction of the lower side in the direction of gravity to prevent the transmission of condensed water. In the configuration described in Patent Document 1, the connecting rod, which is the main component, is made of a soft metal, so that it can be freely deformed and bent, and is easy to mount. It was difficult to fix the lens in a desired position. In addition, since a soft metal connecting rod is insert-molded into a synthetic resin clip, there is a problem that the molding cost is high.

  The present invention has been made to solve the above-described problems, and protects the wiring from the edges of the internal components of the hot water storage hot water heater, prevents water from splashing on the wiring connection portion, and provides stable wiring. An object of the present invention is to provide a hot water storage type water heater that can be used.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element which is common in each figure, and the overlapping description is abbreviate | omitted.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram illustrating a hot water storage type water heater according to Embodiment 1 of the present invention. As shown in FIG. 1, the hot water storage type water heater 50 according to the first embodiment includes an HP unit 1 and a hot water storage tank unit 40. The hot water storage tank unit 40 includes a hot water storage tank 10 having a substantially cylindrical shape and an exterior case 30 having a substantially rectangular parallelepiped shape. The hot water storage tank 10 is accommodated in the exterior case 30 in a state covered with a heat insulating material to be described later. The HP unit 1 functions as a heating unit that generates hot water by heating water with a heat pump cycle. Hot water stored in the hot water storage tank 10 is supplied to a predetermined hot water supply destination as necessary. The heating means of the present invention is not limited to the heat pump type, and may be any configuration such as a configuration in which a heater is installed in the hot water storage tank 10.

  Connected to the lower part of the hot water storage tank 10 are a water supply pipe 11 and an HP forward pipe 13 a for sending low temperature water in the hot water storage tank 10 to the HP unit 1. Further, an HP return pipe 13 b for returning hot water heated by the HP unit 1 into the hot water storage tank 10 is connected to the upper part of the hot water storage tank 10. The hot water supply pipe 12 is a pipe for supplying hot water to a predetermined hot water tap (not shown) such as a bathroom shower or a kitchen faucet. The bath piping 14 is a piping for supplying hot water to a bathtub (not shown).

  An upper surface of the outer case 30 of the hot water storage tank unit 40 is constituted by a top plate 32. Further, a recessed portion 31 is formed at the lower portion of the outer case 30 so that the front side is retracted. The retracting section 31 is configured to draw each of the water supply pipe 11, the HP forward pipe 13 a, the HP return pipe 13 b, the hot water supply pipe 12, and the bathroom forward pipe 14 into the hot water storage tank unit 40 or from the hot water storage tank unit 40. A pipe connection for drawing out is provided.

  Support legs 35 are connected to the lower part of the outer case 30. The hot water storage tank unit 40 is installed on the base C by fixing the support legs 35 to the concrete base C with anchor bolts (not shown). In addition, a pipe cover (not shown) is provided below the outer case 30 in order to improve the design of the hot water storage tank unit 40 by covering the pipe connections and the pipes connected to the pipe connections. .

  In the hot water storage type hot water heater 50 having the above-described configuration, the hot water storage tank 10 is always filled with the high temperature hot water in the upper layer and the low temperature water in the lower layer by the water supply from the water supply pipe 11, and the hot water in the hot water storage tank 10 is maintained. A constant water supply pressure is applied to the water supply pipe 11. At the time of boiling operation, the low temperature water in the lower part of the hot water storage tank 10 is sent to the heat exchanger in the HP unit 1 through the HP outgoing pipe 13a, and is boiled by the heat exchanger to become hot hot water. The hot water returns to the hot water storage tank 10 through the HP return pipe 13b and flows into the hot water storage tank 10 from above.

  Further, at the time of hot water supply, hot water in the hot water storage tank 10 flows into the hot water supply pipe due to the water supply pressure from the water supply pipe 11, and the hot water and low temperature water from the water supply pipe 11 are mixed by the mixing valve. Thus, hot water having a hot water temperature set by a user with a remote controller (not shown) is generated, and the hot water is supplied to a predetermined hot water tap or a bathtub in the bathroom, kitchen, etc. through the hot water supply pipe 12 or the forward piping 14. Is done.

  As described above, in the hot water storage tank unit 40, each of the water supply pipe 11, the HP forward pipe 13 a, the HP return pipe 13 b, the hot water supply pipe 12, and the bath pipe 14 drawn from the retracting portion 31 is stored in the hot water storage tank. 10 and the outer case 30. Similarly, the functional parts and the wiring for performing the operation and control of the hot water storage water heater 50 built in the hot water storage tank unit 40 are also arranged in the space between the hot water storage tank 10 and the outer case 30. become. In addition, each pipe inside the hot water storage tank unit 40 is connected to the other part at two ends by a metal pipe connecting part fastening part. The piping is designed so that it can be installed with a certain amount of play while ensuring water tightness at the piping connection, which is the connection with the mating parts, in consideration of convenience during assembly. May vary depending on the assembly work of the worker who performs the assembly. In addition, the relative positional relationship between the pipes may change, which may cause contact between adjacent pipes and other parts.

Further, in addition to the above-described metal pipe connection part fastening parts, there are sheet metal edges and the like for fixing functional parts inside the hot water storage tank unit 40. It is necessary to prevent the wiring from coming into contact with these edges. Further, since there is a temperature difference between the atmospheric temperature inside the hot water storage tank unit 40 and the temperature of the hot water flowing in the pipe, dew condensation water may be generated on the pipe surface due to the temperature difference, and the wires are connected to each other. It is also necessary to prevent dew condensation from entering connectors such as connectors. Conventionally, in order to protect the connection part of the wiring, the wiring is taped so that the condensed water does not reach the connection part by allowing the wiring length to be slack and allowing the wiring below the wiring connection part to sag. 10 was fixed to a heat insulating material covering 10. Further, the wiring connection portion is fixed to the heat insulating material of the hot water storage tank 10 so as to be covered with the tape, and the water splash is prevented by the tape. When fixing the wiring to the heat insulating material of the hot water storage tank 10 with a tape, there are many cases where piping or functional parts are present in front of the tape application location, and the workability is poor and the application position varies. .

  FIG. 2 shows the clamper 20 that is a fastening part made of synthetic resin for fixing adjacent piping and wiring of functional parts in the hot water storage type water heater 50 according to Embodiment 1 of the present invention. The clamper 20 extends from the pipe attachment part 21 that can be attached to adjacent pipes, the connection part 22 that connects the two pipe attachment parts 21, and the two connection parts 21, and is separated from the two pipe attachment parts 21 by a predetermined distance. The wiring attachment part 23 for holding the wiring configured as described above is provided. Further, the wiring attachment portion 23 of the clamper 20 is provided at a position that is upward in the vertical direction when the pipe attachment portion 21 is attached to the pipe.

  Next, the operation will be described. FIG. 3 shows a clamper connected to the wiring 18 of functional parts built in the hot water storage tank unit 40 which performs the operation and control of the hot water supply pipe 12 adjacent to the inside of the outer case 30, the bath pipe 14, and the hot water storage type water heater 50. It is a figure showing the state where 20 was attached. In the present embodiment, the pipe mounting portion 21 of the clamper 20 is attached and fixed to the adjacent hot water supply pipe 12 and the forward piping 14, and the wiring 18 is fixed to the wiring mounting portion 23. By fixing the hot water supply pipe 12 and the forward piping 14 with the clamper 20, fluctuations in the relative positional relationship between the pipe and the wiring due to rotation of the pipes and assembly variations can be suppressed. Since the wiring attachment portion 23 of the clamper 20 is located above the piping attachment portion 21, the condensed water from the hot water supply pipe 12 and the forward piping 14 is not transmitted from the clamper 20 to the wiring 18. In addition, since the wiring attachment portion 23 is separated from the two piping attachment portions 21 by a predetermined distance, the hot water supply piping 12 and the forward flow are more than when the wiring attachment portion 23 is closer to one of the piping attachment portions 21. The possibility that the wiring 18 is in contact with the pipe 14 can be reduced. As shown in FIG. 3, if the wiring near the connecting portion between the wirings is fixed to the wiring fixing portion 23 and the wiring 18 has slack, the wiring connecting portion even if the wiring 18 contacts the hot water supply pipe 12 and the forward piping 14. Water is not transmitted to. Further, according to the present invention, the wiring 18 can be fixed if there is the hot water supply pipe 12 and the forward piping 14 even when there is no support sheet metal for supporting and fixing the wiring nearby. In the above-described example, the two adjacent pipes have been described as the hot water supply pipe 12 and the forward pipe 14, but the other two pipes may be arbitrarily selected, and the same effect is obtained. The same applies to the following embodiments.

  As described above, in the present embodiment, even when there is no support sheet metal or the like, the wiring 18, the hot water supply pipe 12, and the drift pipe 14 can be fixed, and the hot water supply pipe 12 and the drift pipe 14 are assembled. The variation can be suppressed, and the edge of the wiring 18 can be protected and the water splash can be prevented.

Embodiment 2. FIG.
Next, another embodiment of the present invention will be described. FIG. 4 is a diagram showing the clamper 20 according to the second embodiment of the present invention. The clamper 20 shown in the figure has the above-described embodiment in that a convex portion 24 that protrudes downward in the vertical direction when attached to the pipe is formed between the pipe attaching portion 21 and the wiring attaching portion 23 of the connecting portion 22. The difference from the first embodiment is that the same or corresponding parts as those in FIGS. 1, 2, and 3 described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  According to the configuration of the second embodiment, when the hot water supply pipe 12 and the bottom pipe 14 are attached to the clamper 20, the dew condensation water from the hot water pipe 12 and the bottom pipe 14 is connected from the pipe attachment portion 21 to the connecting portion 22. , And then falls downward from the convex portion 24, so that it is possible to prevent the condensed water from being transmitted to the wiring 18.

  As described above, in the second embodiment, in addition to the effects in the first embodiment, the action of the convex portion 24 can more reliably prevent water splashing on the wiring 18.

Embodiment 3 FIG.
Next, another embodiment of the present invention will be described. FIG. 5 is a diagram showing the clamper 20 according to the third embodiment of the present invention. The clamper 20 shown in the figure is composed of two parts, a pipe attachment part 21 and a connection part 22a, a pipe attachment part 21, a connection part 22b, and a wiring attachment part 23, and engages and connects the connection parts 22a and 22b. Thus, the length can be adjusted, which is different from the first embodiment, and the same or corresponding parts as those in FIGS. 1, 2, and 3 described in the first embodiment are denoted by the same reference numerals. The description is omitted.

  A plurality of holes 25 are formed in the connecting portion 22a. The connecting portion 22b is provided with a plurality of convex portions 26 that engage with the holes 25 of the connecting portion 22a. The length of the connecting portion 22 of the clamper 20 can be changed by engaging the holes 25 and the convex portion 26 in accordance with the distance between the hot water supply pipe 12 and the forward piping 14. Further, by providing a plurality of convex portions 26, the connecting portions can be reliably fixed when the length of the connecting portions is adjusted. If it is fixed at one place, it cannot be reliably fixed by rotating at the engaging portion. FIG. 6 shows a perspective view of the connected clamper 20 after engagement.

  As described above, in the present embodiment, the positions of the hot water supply pipe 12 and the forward piping 14 can be designed without matching the distance between the pipe mounting portions 21 of the clamper 20, and there is no support sheet metal or the like. However, the wiring 18 and the pipes 15 and 16 can be fixed, the assembling variation of the hot water supply pipe 12 and the forward piping 14 can be suppressed, and the edge of the wiring 18 can be protected and the water splash can be prevented.

  As mentioned above, although the hot water storage type hot water heater of the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment. For example, the position of the wiring attachment portion 23 has been described mainly in the case where the wiring attachment portion 23 is provided above the piping attachment portion 21 in the vertical direction and the wiring 18 passes between the piping attachment portions 21. However, as shown in FIGS. 7 and 8, for example, when the wiring attachment portion 23 is vertically above the piping attachment portion 21 and the clamper 20 is attached, the wiring attachment portion 23 is outside the piping attachment portion 21 when viewed from above. The wiring 18 may pass through the outside of the two pipes (the hot water supply pipe 12 and the forward pipe 14) to which the clamper 20 is attached. Thereby, there is an effect in preventing water splashing from the hot water supply pipe 12 and the forward pipe 14 of the wiring 18 when the distance between the pipes is short. FIG. 7 is a top view of the hot water supply pipe 12 and the clamper 20 for attaching the wiring 18 to the outside of the flow-out pipe 14, and FIG. 8 is a perspective view of FIG.

  In addition, with regard to the opening of the pipe mounting portion 21, the first to third embodiments described above show a configuration in which an opening is provided on the side opposite to the connecting portion 22, and shows two pipes (a hot water supply pipe 12 and an outlet pipe 14. However, the opening of the pipe mounting portion 21 is in the same direction as shown in FIG. 9, for example, and the hot water supply pipe 12 is attached to the pipe. And it may be configured to be attached from the same direction without moving the forward piping 14. FIG. 9 is a perspective view of the clamper 20 with the opening of the pipe mounting portion 21 in the same direction. As shown in FIG. 10, since the opening of the pipe mounting portion 21 is made in the same direction, the clamper 20 can be mounted from one direction without moving the hot water supply pipe 12 and the forward piping 14, so that the assembly workability is improved. Can be improved. In addition, since it is not necessary to move the pipe when the clamper 20 is attached, there is an effect that a load is not applied to the pipe connection portion or the like.

  Further, regarding the connecting portion 22, in the third embodiment, the configuration of the clamper 20 that can change the length of the connecting portion 22 by making the clamper 20 into two parts and engaging the hole 25 and the convex portion 26 of the connecting portion 22 will be described. However, for example, the engagement portion of the connecting portion 22 is formed in a U shape, the inner surface is a saw roof surface, and the length can be adjusted by pushing the engagement portion as much as necessary. Also good. Thereby, the length adjustment of the connection part 22 can be finely adjusted.

  Further, in the first to third embodiments, the case where there is one wiring mounting portion 23 has been described with respect to the wiring mounting portion 23. However, the present invention is not limited to this, and one clamper 20 may have two or more wiring mounting portions 23. Good. If comprised in this way, a different kind of wiring can be divided and attached by using two or more wiring attachment parts 23 separately. In addition, it is possible to use different mounting locations according to the stage of assembly of the water heater. In addition, by changing the extending direction of the plurality of wiring attachment portions 23 provided, it is possible to change the orientation of the wiring attachment state.
