JPS60147064A - Antifreezing measure - Google Patents

Abstract

PURPOSE:To enable to prevent a heat exchanger from freezing by a constitution wherein both an incoming water pipe and an outgoing hot water pipe, part of each of which is formed integral with an elastic body bonded with a vibrator, are connected to the heat exchanger. CONSTITUTION:A step-down transformer 1 is housed in a remote controller and power is transmitted through service lines 8 to an appliance main in parallel to a control circuit 6 and to a low temperature operating switch 2 and vibrators 10, which are bonded to elastic bodies such as rubbers or the like comprising the parts of an incoming water pipe 5a and of an outgoing hot water pipe 5b, both connected to a heat exchanger 4. Concretely, vibration is caused in the water within the heat exchanger 4, the incoming water pipe 5a and the outgoing hot water pipe 5b, resulting in realizing antifreezing effect without the necessity of inputting commercial power supply in the main body and at the same time the use of a heater with high power consumption.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an antifreeze device used in water heaters, hot water heaters, and the like.

Conventional structure and its problems A conventional antifreeze device for, for example, an electric water heater has a structure as shown in FIG. That is, the commercial power source is directly inputted to the low temperature operation switch 2 and the electric heater 3, and the pressure reducing 21-mm transformer 1 for the control circuit 6 is connected in parallel with the low temperature operation switch 2 and the electric heater 3. The electric heater 3 was in contact with the heat exchanger 4, the water inlet pipe 5a, and the hot water outlet pipe 5b to warm the water therein and prevent it from freezing.

In this case, since commercial power is input directly to the main unit, there is a risk of electric shock etc. if it is installed in a humid place such as a bathroom.
I had to take some kind of countermeasures. Further, since the heat exchanger 4 has a large capacity, the electric heater consumes a large amount of power, and the electricity bill becomes expensive.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks, and aims to avoid direct input of commercial power to the main body and prevent freezing with low power consumption.

Structure of the Invention In order to achieve the above objects, the present invention provides a heat exchanger, a water inlet pipe and a hot water outlet pipe connected to the heat exchanger and partially formed integrally with an elastic body such as rubber, and a water inlet pipe and a hot water outlet pipe connected to the heat exchanger, and It consists of a vibrating body that is in close contact with the water in the heat exchanger and water inlet and outlet pipes, and has the effect of preventing freezing by applying vibration to the water in the heat exchanger and water inlet and outlet pipes.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, the pressure reducing transformer 1 is housed in a remote controller 7, and power is transferred to the device main body 9 using a supply line 8. FIG. 3 shows an outline of the internal configuration.

The voltage carried by the supply line 8 is supplied in parallel with the control circuit 6 to the cold-operated switch 2 and to the vibrating body 10 . The vibrating body 10 is an elastic body 1 that forms part of the water inlet and hot water outlet pipes 5.
It is closely attached to 1.

The operation of the above configuration will be explained below.

When the outside temperature drops and there is a possibility of freezing, the low temperature operation switch 2 is turned on and the vibrating body 10 starts vibrating. Then, the elastic body 11 in close contact with the vibrating body 10 also begins to vibrate, giving vibration to the water inside. Water has the property of being less likely to freeze when it is moving, so it has an antifreeze effect.

As described above, according to this embodiment, there is no need to input commercial power into the main body, and at the same time, it is possible to provide an antifreeze effect without using a heater that consumes high power.

Effects of the Invention As described above, according to the present invention, the following effects can be achieved.

(1) There is no need to directly input commercial power to the main unit, so
There is no risk of electric shock even when installed in a humid place such as a bathroom.

2) Since there is no need to directly input commercial power to the main unit, earth leakage countermeasures are simplified.

■ Saves energy because it does not use a heater that consumes a lot of power.
