Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water heating device that uses heat radiation to boil water by utilizing the heat radiation generated when a compressor compresses refrigerant gas when a refrigerator seat or cooler is operated. It is something.

Conventional technology For example, the mechanical part that performs the cooling action of an electric refrigerator is a combination of a compressor, a compressor motor, a refrigerant control device (capillary tube), a condenser, an evaporator, an expansion valve, etc. These devices are connected by refrigerant gas piping.

These effects occur when the liquid refrigerant in the evaporator evaporates, and the gaseous refrigerant created by cooling and evaporating the area around the evaporator is sucked into the compressor and compressed. It becomes a high-temperature, high-pressure gaseous refrigerant and is sent to the condenser.

This condenser is a radiator-type condenser that has a good heat dissipation effect to cool the high-temperature, high-pressure gaseous refrigerant. This cools the high-temperature, high-pressure gas and turns it into a low-temperature, high-pressure liquid refrigerant.

This high-pressure liquid refrigerant is adiabatically expanded in a refrigerant controller (capillary tube) with a diameter of 0.5 to 1 mm to become a low-temperature, low-pressure liquid refrigerant, flows into an evaporator, and repeats the same action again. , which cools the inside of the refrigerator through circulation.

Additionally, a motor, temperature regulator, motor overload protection device, and defrosting device are installed. This defrosting device prevents the moisture inside the refrigerator from forming frost on the evaporator. .

There are two types of this: natural melting type and superheated melting type. In the former, the front-view compressor is stopped and the frost is removed using outside air, while in the latter, the high-pressure gas is pumped into the condenser while the compressor is still running. There are two types: one that melts the frost by bypassing the evaporator (without a condenser), and one that melts the frost by installing a heater on the surface of the evaporator and energizing it.

The refrigerant used in compression refrigerators is Freon refrigerant R-1.
2, or the refrigerant R-22, which evaporates at low temperatures and easily liquefies, is not flammable or explosive, and is harmless to humans.

At the boiling point of refrigerant R-12 under atmospheric pressure, -3
0 degrees, and the boiling point of refrigerant R-22 (7) is -40 degrees.

When installing equipment such as large refrigerators, freezers, or split-type coolers, it is important to connect the indoor unit to the outdoor unit in order to make it easier to install the indoor unit and outdoor unit, or to install noisy driving mechanical parts outdoors. A refrigerant gas piping section connecting the outdoor unit is provided outdoors.

Problems that the invention aims to solve When a refrigerator, freezer, split type cooler, etc. is operating, the refrigerant gas piping connecting the indoor unit and outdoor unit is in a high temperature state, and this high temperature is directly transferred to the outside air. Since the heat is lost, the heat dissipation is wasted and is not used effectively.

The purpose of the present invention is to eliminate such drawbacks by boiling water using the high temperature heat radiated from refrigerant gas piping, and using this hot water for many purposes such as washing dishes, heating, and defrosting refrigerators. The goal is to

Means for Solving the Problems In order to achieve the above object, the present invention provides a motor for a compressor that operates intermittently, and a motor driven by the motor,
and a compressor for compressing refrigerant gas, a pipe connected to the compressor side and into which circulating refrigerant gas flows, a plurality of bent portions formed in the refrigerant gas pipe, the bent portions being folded inwards, and A water boiling tank with a water inlet and a drain port is provided, and a condenser converts the high temperature and high pressure gaseous refrigerant to low temperature and high pressure. The idea is to boil the water in the water heating tank by the heat radiated from the pipes when it flows into the water tank.

The refrigerant gas is compressed by the compressor driven by the motor for the compressor, which operates intermittently, and the high-temperature refrigerant gas flows into the piping. It reaches a high temperature and can boil the water in the kettle tank.

Additionally, switching valves installed at the water supply and drain ports operate to replenish and drain water from the water heating tank.

Example An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged sectional view of the main parts, and FIG. 2 is a layout diagram showing how each unit is connected to piping.

A compressor motor M that operates intermittently depending on a temperature difference or the passage of time, and a compressor C that is driven by the motor M and compresses refrigerant gas are provided.

A circulating refrigerant gas pipe 1 connected to the compressor C side and forming a plurality of bent portions n is installed inside the water heating tank HT.

This water boiling tank HT has a water supply port 2 and a drain port 3,
Switching valves 2' and 3' are provided to open and close the water supply port 2 and the drain port 3.

In addition, a condenser CO is connected to piping 1 of this water heating tank and converts the high temperature and high pressure gaseous refrigerant to a low temperature and high pressure.
will be established.

Therefore, water heating tank HT will be placed between compressor C and condenser 〇〇, so
When high-temperature refrigerant gas flows through the meandering pipe 1 in the water heating tank HT, water in the water heating tank can be boiled by heat radiation from the pipe.

Alternatively, connect the condenser 〇〇 directly to the evaporator (evaporator) AC side with pipe 1, or boil the water W in the tank HT, and it will become low temperature and low pressure. After cooling the AC, the refrigerant gas at room temperature and low pressure flows to the compressor C again and is repeatedly circulated, cooling the inside of the refrigerator at the same time.

Effects of the Invention As described above, the present invention provides a compressor motor that operates intermittently, a compressor that is driven by the motor and compresses refrigerant gas, and a pipe that is connected to the compressor and that allows circulating refrigerant gas to flow in. A water heating tank is formed in which multiple bent portions are formed in the refrigerant gas piping, the bent portions are installed internally, and has a water supply port and a drain port. A water heating tank is installed between the compressor and the condenser, and when high-temperature refrigerant gas flows through the piping in the water heating tank, the water in the water heating tank can be boiled by heat radiation from the piping. Therefore, it is also possible to dissipate it wastefully or to use a resistor tank RT in between.

In addition, a thin pipe P is installed in this water boiling tank HT, and the other end P' of this pipe P is connected to an evaporator AC installed in a refrigerator CB, freezer, split type cooler, etc.
It can also be connected to or placed nearby to defrost the evaporator AC.

Therefore, hot water can be used even when the motor M is stopped, so the electric heater becomes unnecessary, and losses due to failure or replacement of the electric heater can be eliminated.

Furthermore, in winter, by placing the pipe P'' provided at the drain port 3 of the water heating tank HT indoors, it can be used for heating.

A refrigerant gas pipe 1 connected to an evaporator AC is provided, and this pipe 1 is connected to a compressor C which repeats compression operations by a compressor motor M.

Therefore, it is possible to effectively use the heat dissipated from the hot water heater, and since the high temperature refrigerant gas can be cooled with water, the motor and compressor can be made smaller, allowing for more space. Not only does it not consume electricity, but it also uses less electricity, so you can save electricity.

Therefore, it is possible not only to save energy by saving electricity, but also to be able to kill two birds with one stone by boiling water while achieving this energy saving, which is an excellent effect.
