この発明は、貯湯式給湯器から給湯を行う浴槽の追いだ
き装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bathtub refilling device that supplies hot water from a hot water storage type water heater.

湯を強制循環し、加熱する方法を取ることがてきる。[Prior Art] A bathtub reheating device is a device that raises the temperature of hot water in a bathtub to a desired temperature when the temperature of the hot water in the bathtub has dropped by -2 degrees, and is equipped with an instantaneous water heater that uses scum, oil, etc. In a bathtub, the water heater can be used to forcibly circulate and heat the hot water in the bathtub using a pump or the like.

を行っている。However, in a bathtub that is not equipped with a water heater as described above, for example, hot water is supplied by a hot water storage type water heater such as a late-night electric water heater, such refilling is not possible. Therefore,
In a bathtub that uses such a storage type water heater to supply hot water, in order to raise the water temperature that has dropped to the appropriate temperature, in a conventional bathtub, new hot water is poured into the bathtub from the storage type water heater. However, a separate heating device is installed for reheating.

ことになる。For hot water baths, it is necessary to manually open the hot water faucet, allow the hot water to flow into the bathtub, and then manually judge the rise in water temperature while stirring, and then close the hot water faucet when the temperature reaches the appropriate temperature. Also,
Sashiyu increases the amount of hot water in the bathtub. For example, suppose there is 200L of hot water at a temperature of 38°C in a bathtub, and if the temperature of this hot water is not raised to 42°C, and the temperature of the hot water is 80"C, the formula is 200L x 38°C.
+X t X 806C(200+X) t, X
At 42°C, it is necessary to perform a bath of X-21, that is, 21 μm. Therefore, if the temperature of the hot water in the bathtub is low, a large amount of hot water will be required and the hot water will overflow from the bathtub.

However, it is economically wasteful to install a separate heating device. This requires a condyle, which is a tedious task when not taking a bath. In addition, since the temperature of the hot water is high, there is a risk of burns, and the amount of hot water in the bathtub increases due to the hot water, which causes overflow and is not efficient.

得ることを目的としている。This invention was made to solve this problem, and even in a bathtub where hot water is supplied by a hot water storage type water heater, there is no need for pouring hot water or having a separate heating device.
The purpose of the present invention is to obtain a bathtub refilling device that can perform refilling safely and efficiently.

ととした。[Means for Solving the Problems] The bathtub refilling device according to the present invention includes a heat exchanger between the hot water storage type water heater and the bathtub, so that the hot water stored in the hot water storage type water heater and the inside of the bathtub can be exchanged. The hot water in the bathtub was circulated through this heat exchanger, and the hot water in the bathtub was expelled by heat exchange.

Since the hot water in the bathtub is circulated and expelled by heat exchange, there is no need for hot water to be poured or a separate heating device, even in bathtubs that use hot water storage type water heaters. This allows for safe and efficient tailgating.

ポンプ（７）および第２のポンプ（９）を停止する。The hot water flowing into the first circulation path (6) and the hot water flowing into the second circulation path (8) exchange heat with each other when they reach the heat exchanger (10). Circulation route (
The hot water in the bathtub 12) flowing through the bathtub 8) is displaced by hot water from the hot water storage type water heater (1) through heat exchange, and then flows back into the bathtub (12). Therefore, the temperature of the water inside the bathtub (12 inches) is
The mixture is stirred by the reflux from the second circulation path (8), and the temperature increases almost uniformly. A temperature sensor (11) installed in the second circulation path (8) detects this rise in water temperature and reports it to the remote control (13), which uses a bathtub water temperature setting device to set the temperature in advance. When the water temperature in the bathtub 12) rises to the set water temperature, a command is issued to stop the first pump (7) and the second pump (9).

を取ることができる。The operation of the remote control (13) is set so that if you press the -degree reheating start switch, recharging will be performed automatically when the water temperature in the bathtub (12) drops again after recharging is complete. There are two methods that can be used: one is to set the water so that the water will not be flushed unless the water heater switch is pressed again.

なる恐れがある。The hot water from the storage type water heater (1) flowing through the first circulation path (6) is cooled by the cold water from the second circulation path (8) in the heat exchanger (1o), and then returned to the storage type water heater (1). Water heater (1
). However, even though this circulating hot water has been cooled through heat exchange, it still remains at a sufficiently high temperature, so it needs to be used again for hot water supply. In other words, for economical reasons, the hot water storage type water heater (1) that uses electricity at night, etc., only holds the minimum amount of hot water that can cover the daily hot water supply load, so it is necessary to If you consume this hot water, you may not be able to supply enough hot water.

ている。Regarding the usage status of hot water storage type water heaters (1) in general households, supplying hot water to the bathtub (12) and recharging are the largest hot water supply loads, and in general, requests for hot water supply and recharging to the bathtub (12) This occurs during the evening and night hours of -day. Therefore, during this time period, hot water storage type water heaters (
In 1), more than half of the total amount of hot water has already been consumed by the hot water supply up to that point, and the layer of low-temperature water still being supplied from the water supply pipe (3) is more than half the height of the hot water storage tank. It becomes.

設ける必要がある。If the hot water that has circulated from the first circulation path (6) is returned to this layer of water, it will be cooled and cannot be used again as hot water for hot water supply. For this reason, the location of the piping that returns the hot water that has been circulated back to the hot water storage type water heater (1) is
As shown in the figure, it is necessary to install it at a height of about 2/3 of the height of the hot water storage tank.

られており、この加工は容易ではない。In addition, the hot water storage type water heater (1) generally has only two piping facilities: a water supply port for supplying water from the outside and a hot water supply port for supplying heated hot water to each load. In order to do this, the hot water storage type water heater <1) must be modified to provide another circulation port. However, the hot water storage type water heater (1) is made of enameled iron plate or stainless steel, and this processing is not easy.

The hot water supply pipe (15) and the circulation pipe (16) connected to the first circulation path (6) are integrally formed.
4), the recirculation hot water outlet of the recirculation piping (16) is opened at a height of 2/3 of the height of the hot water storage tank.

Since we decided to circulate the hot water to the heat exchanger and drive out the hot water in the bathtub by heat exchange, even in bathtubs that are supplied with hot water by a storage type water heater, it is possible to use hot water directly or to install a separate heating device. It is not necessary, and one effect is that it allows for safe and efficient tailgating.]
