Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat-retaining circulation device intended for hot water tanks such as baths and heated pools.

[Prior Art] Conventionally, this type of heat retention circulation device has used an electric heater or a boiler as a heat source for heat retention.

[Problem to be solved by the invention] However, when using an electric heater, the power consumption is large (for example, about 700W to IKW for a home bath), so if you try to use other home appliances, the contract power will also be charged. It needs to be bigger.

The above problem can be avoided if the use of other home appliances, etc. does not overlap with the use of the electric heater, and if the heating circulation device itself can be used when other home appliances, etc. are used. be. In other words, this is a problem that arises because power consumption cannot be smoothed, and can be avoided if the heat supplied by the electric heater can be stored.

On the other hand, when a boiler is used, it takes time and effort to install fuel piping and replenishment.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a heat-retaining circulation device having a heat-retaining heat source that can store heat supply and is easy to use.

[Means for Solving the Problems] In order to solve the above object, the present invention provides a heat retention circulation device that circulates water in a hot water tank through a circulation path and includes a heat source in the circulation path. The main idea is to install a heat storage tank.

Further, the circulation path is composed of a main circuit and a sub-circuit connected via a distributor whose distribution ratio can be changed, and the main circuit is provided with a heat storage tank.

[Function] In the present invention, for example, the heat storage material in the heat storage tank is heated late at night to store heat in the heat storage tank, and when used during the daytime, water is heated by passing through the heat storage tank.

Also, when the temperature of the water in the hot water tank is high, the distributor increases the amount of water that flows through the circulation path and enters the subcircuit, and conversely, when the temperature of the water in the hot water tank is low, The distributor increases the amount of water flowing through the circulation path that enters the main circuit.

[Example] Hereinafter, an example in which the present invention is applied to a household bath will be described with reference to FIGS. 1 to 5.

As shown in Fig. 1, the suction port 2 provided in the bathtub l
and the hot water supply port 3 are connected by a hot water flow path A. This hot water flow path A includes a suction path 4 provided between the suction port 2 and the distributor 5, a heating flow path 6 as a main circuit that is separated from the distributor 5, and a non-heating flow path 7 as a subcircuit. , one hot water supply channel 8 in which the heating channel 6 and the non-heating channel 7 are connected.
It consists of

The suction path 4 is provided with a pump 9 for sucking hot water from the bathtub 1 and a purification device 10.

As shown in FIGS. 2 and 3, the distributor 5 is composed of a distributor main body 11, a valve body 14, and a pulse motor I2 connected to the valve body 14.

This distributor main body 11 has a cylindrical shape, and a valve body 14 is mounted inside thereof so as to be rotatable in the axial direction.

The suction channel 4 is connected to one end of the distributor body 11, and the heating channel 6 and the non-heating channel 7 are connected to the other end of the distributor body 11. The valve body 14 includes a heating flow path 6,
A flow path I5 having the same diameter as the non-heating flow path 7 is provided. The flow path 15 of the valve body 14 can be in a state where it matches the heating channel 6 as shown in FIG. 4, or a state where it matches the non-heating channel 7 as shown in FIG. As shown in FIG. 3, the flow path 15 of the valve body 14 can be located between the heated flow path 6 and the non-heated flow path 7, and the flow path I5 of the valve body 14 can be positioned between the heated flow path 6 and the non-heated flow path 7. The part matching the heating channel 6 and the non-heating channel 7

As shown in FIG. 1, the heating channel 6 is arranged in a meandering manner within the heat storage tank 16. A brick-shaped heat storage material made of sodium acetate or the like is stored in the heat storage tank 16, and a heater 17 is provided adjacent to the heat storage material.

Further, the pulse motor 12 of the distributor 5, the heater 17, the temperature sensor 20 provided in the hot water supply channel 8, and the control device 18 are connected by signal cables K, respectively. The control device 18 is capable of arbitrarily selecting a set temperature T using an operation panel (not shown).

Now, the operation of this embodiment configured as described above will be explained.

In this embodiment, hot water in the bathtub 1 is constantly sucked up into the suction path 4 by the pump 9, passed through the purifier 101 distributor 5, and then through the heated flow path 6 or the non-heated flow path 7.
The hot water returns to the bathtub 1 from the hot water supply channel 8.

At this time, dirt and the like in the warm water sucked up from the bathtub 1 is filtered and removed by the purification device 10.

Heat storage in the heat storage tank 16 of this system is performed by heating the heater 17 late at night. As a result, even if the heater 17 is not operated during the day, the hot water flowing into the heating channel 6 can be transferred to the heat storage tank 1.
It is heated by flowing through 6.

On the other hand, the hot water flowing in the non-heating channel 7 flows from the non-heating channel 7 to the hot water supply channel 8 without being heated.

Note that the amount of hot water flowing to the heating channel 6 side and the amount of hot water flowing to the non-heating channel 7 side are calculated and determined by the control device 18. The control device 18 compares and calculates the temperature T1 detected by the temperature sensor 19 and a preset temperature T (in this embodiment, it can be set variably between 38°C and 44°C), and adjusts the temperature of the valve body 14. The temperature of the hot water from the hot water supply port 3 is kept constant. That is, Tt
>'r, the pulse motor 12 is driven to switch the valve body 14 to the non-heating channel 7 side (see FIG. 5), and control is performed so that TI=T. Further, when Tr<T, the valve body 14 is switched to the heating flow path 6 side (see FIG. 4) and controlled so that T1=T.

In this embodiment, the heat storage tank 16 is installed in the middle of the night using late-night electricity.
Since heat can be stored in the heat storage material constituting the bath, there is no need to operate the heater 17 when using the bath during the day or at night.

Therefore, the use of home appliances during the day and the operation of the heater 17 of the heat-retaining circulation device do not overlap.

In other words, the power consumption can be smoothed out within a day,
The contract power will not be exceeded. Therefore, there is no need to increase the contract power. Also, since late-night electricity is used, running costs are low.

Note that the present invention is not limited to the above embodiments,
For example, you may do as follows.

(b) In addition to baths, it should be embodied in heated pools.

(b) A temperature sensor ■9 is also provided in the heat storage tank 16, and when the temperature of the heat storage tank weight 6 falls below the heat storage start temperature, the heater 1
7 is operated, and when the temperature rises and the temperature of the heat storage tank 16 becomes equal to or higher than the heat storage stop temperature, the control device 18 controls the operation of the heater 17 to be stopped.

[Effects of the Invention] As described in detail above, in the present invention, the supply of heat can be stored, so power consumption can be smoothed, and it can be used easily.

In addition, since the amount of water flowing through the main circuit can be controlled using a distributor, even if the water in the hot water tank is constantly circulated, heating in the heat storage tank can be avoided if the water temperature in the hot water tank is high. can.
