Description

  The present invention relates to a hot water boiler for hot water mats, and more particularly to a hot water boiler for hot water mats that significantly improves the circulation efficiency of hot water.

In general, the hot water mat is a heating mat heated by hot water supplied by a small hot water boiler in which a hot water hose through which hot water circulates is built in the mat main body and connected to the mat main body by a connecting hose.
Such a hot water mat has the advantage of completely eliminating the problems of existing electric mats with built-in electric heating wires inside the mat body, that is, the danger of fire and electric shock due to harmful electromagnetic waves and electric hot wires. .
However, most of the hot water boilers widely used in existing hot water mats use an electric motor pump to circulate the hot water heated by the electric heater, but such hot water boilers for hot water mats are hot water. Not only is the durability significantly reduced due to frequent failures of the electric motor pump operating in the environment, but the noise and vibration of the motor during driving of the electric motor pump is transmitted to the outside as it is and unpleasant noise is generated. There was a problem that disturbed.

In addition, such an existing hot water boiler for hot water mats is an electric motor pump that circulates hot water when the hot water hose of the hot water mat breaks due to carelessness of the user, or when the connecting hose breaks and the hot water circulation is blocked. As a result, the durability is remarkably lowered.
In order to solve such problems, there has been devised a hot water boiler for hot water mats that circulates hot water inside the hot water mat using the steam pressure generated in the hot water heating tank during hot water heating. The natural circulation hot water boiler using such steam pressure is excessive when the hot water mat hose is folded by the carelessness of the user, or when the connecting hose is broken and the hot water circulation is blocked. There was a built-in risk of explosion due to the generation of vapor pressure.

In order to solve the problems of the natural circulation type hot water boiler using the vapor pressure as described above, the present applicant is configured to circulate the hot water inside the hot water mat using the vacuum suction input. We have applied for hot water boilers and have been registered in Japanese Patent No. 0918522, Japanese Patent No. 0948908, and Japanese Patent No. 1418947.
The hot water boiler for hot water mats filed by the present applicant is connected to a hot water heating tank equipped with an electric heater and a hot water storage tank is connected, and the hot water generated in the hot water heating tank is heated by the electric heater. The water inside the hot water mat is circulated using a vacuum suction input formed inside the instantaneous hot water heating rod that moves to the hot water storage rod due to the vapor pressure formed in the heating rod.

However, the conventional hot water boiler for hot water mats configured as described above heats about 150 to 200 ml of water in the hot water heating tub in order to form a vacuum suction inside the hot water heating tub. Since it is a discharge method, it takes about 1 to 2 minutes to form a vacuum suction inside the hot water heating tub depending on the volume of the hot water heating tub. Since the water in the hot water mat is cooled during this period, the circulation efficiency is remarkably lowered.
In order to solve such problems, a method of greatly increasing the volume of the hot water heating tub so that the water inside the hot water mat can be circulated at a time has been considered, but in this case the capacity of the electric heater is excessive. In addition, there are side effects such as water roaring noise and high power consumption. Therefore, existing methods have limited circulation efficiency.

  The present invention relates to a high temperature space portion and a low temperature space portion located on the left and right sides of a concave groove portion formed at the center lower portion of the hot water heating tank, and a discharge space portion and a high temperature space portion connecting the upper portions of the high temperature space portion and the low temperature space portion. And the hot water heating pipe which connects the lower part of a low-temperature space part is formed so that a circulation flow path may be made with a 'R' shape. The hot water heating pipe is installed at an inclination, and an electric heater is installed on the outer surface of the hot water heating pipe. An electric heater is installed outside the hot water heating pipe, and a small amount of water inside the hot water heating tank is instantaneously vaporized using this, and a small amount of hot water is transferred to the hot water storage tank by its vapor pressure. . Thereafter, a small amount of warm water can be continuously circulated over a short period by sucking a small amount of water inside the warm water mat by means of vacuum suction formed inside the warm water heater. For this reason, the circulation efficiency of warm water can be significantly improved as compared with a conventional warm water boiler that forms a vacuum suction by heating all the water in the warm water heating tank.

Hereinafter, the present invention will be described in detail with reference to the drawings.
As shown in FIG. 2, the hot water boiler for hot water mats according to the present invention includes a hot water heating tank 2, a hot water storage tank 10, and a discharge check valve 13a.
The hot water heating tank 2 instantaneously vaporizes a small amount of water filled in the hot water heating pipe 6 by an electric heater 7 exposed to the outside, and discharges a small amount of hot water to the hot water storage tank 10 by its vapor pressure. Then, after discharging the hot water, a small amount of water inside the hot water mat is sucked by the vacuum suction formed, and the concave groove portion 2a is formed in an inverted 'concave' shape at the center lower portion. The high temperature space part 4 and the low temperature space part 5 located on the side, the discharge space part 3 connecting the upper part of the high temperature space part 4 and the low temperature space part 5, and the hot water connecting the high temperature space part 4 and the lower part of the low temperature space part 5 The heating tube 6 is formed in a “R” shape so as to form a circulation channel.

If the hot water heating tank 2 is formed so as to form a “R” -shaped circulation flow path, the hot water heated inside the hot water heating pipe 6 rises to the discharge space portion 3 through the high temperature space portion 4 and then the low temperature space portion. The convection circulation which goes down to meet the cold water 5 and returns to the hot water heating pipe 6 is performed more smoothly. For this reason, not only can the water inside the hot water heating tank 2 be heated more efficiently by the electric heater 7 exposed to the outside, but also a small amount of water is instantly vaporized inside the hot water heating pipe 6. It is possible to move bubbles generated at the time of the discharge in the discharge space portion 3 more quickly.
The discharge space part 3 formed in the upper part of the hot water heating tub 2 is a space in which hot water generated inside the hot water heating tub 2 is discharged, and a hot water discharge end 8 is formed inside the upper surface so as to be inside. The water level detection sensor 3a is installed.

The high temperature space 4 formed on the lower side of the discharge space 3 is a space in which high temperature water generated by the hot water heating pipe 6 stays, and the low temperature space formed on the lower side of the discharge space 3. Reference numeral 5 denotes a space in which low-temperature water sucked from the hot water mat stays, and a hot water recovery end portion 9 connected to the hot water mat is formed on one side.
Although it is possible to install a recovery check valve 9a at the hot water recovery end 9, the recovery check valve 9a moves the hot water inside the hot water mat into the hot water heating tank. The hot water generated by the firewood does not flow back to the hot water mat.

A water level detection sensor 3a installed inside the discharge space 3 of the hot water heating tub 2 is for detecting when the water level of the hot water heating tub 2 falls below the lower end of the hot water discharge end 8. Well-known float type water level detection sensor or electronic water level detection sensor normally used in conventional humidifiers, aquariums, etc. are mainly used, but it becomes narrower due to slimming of hot water boiler In order to easily install in the hot water heating tank 2, it is desirable to use an electronic water level detection sensor that is less bulky and occupies less installation space than a large float type water level detection sensor.
And as shown in FIG. 3, the hot water discharge end part 8 formed in the discharge space part 3 of the hot water heating tank 2 is formed with an air discharge hole 8a communicating with the hot water inflow end part 13 of the hot water storage tank 10. Is desirable.

If the air discharge hole 8 a is formed in the hot water discharge end 8 in this way, even if air flows into the hot water heating rod 2, the hot water storage rod 10 is formed through the air discharge hole 8 a formed in the hot water discharge end 8. The hot water inflow end portion 13 can be automatically discharged.
The hot water heating pipe 6 connected between the high temperature space portion 4 and the low temperature space portion 5 of the hot water heating tank 2 is provided with an electric heater 7 on the outer surface in order to instantaneously vaporize a small amount of water. If the electric heater 7 is installed on the outer surface of the hot water heating pipe 6 as described above, the entire water inside the hot water heating bowl is heated by installing the electric heater inside the hot water heating bowl, thereby Unlike a conventional hot water boiler that cannot instantly vaporize only a small amount of water, only a small amount of water in contact with the surface where the hot water heating tube 6 and the electric heater 7 are in contact can be vaporized instantaneously. .

And although the hot water heating pipe 6 is installed in an inclined manner, a small amount of water inside the hot water heating pipe 6 is instantaneously heated by the electric heater 7 installed outside the hot water heating pipe 6. It is desirable that the air bubbles generated inside the heating tube 6 are installed so as to be inclined upward toward the high temperature space portion 4 so that the bubbles can smoothly escape to the discharge space portion 3 through the high temperature space portion 4.
The hot water heating pipe 6 is preferably made of a material having high thermal conductivity such as aluminum so that the heat source generated by the electric heater 7 is smoothly transmitted to the water passing through the hot water heating pipe 6. .
Moreover, as shown in FIG. 4, it is desirable to form a plurality of heat radiation pins 6a long in the length direction on the inner peripheral surface of the hot water heating tube 6.

In this way, if a plurality of heat radiation pins 6a are formed in the longitudinal direction on the inner peripheral surface of the hot water heating tube 6, the heat source generated by the electric heater 7 is more smoothly conducted to the water inside the hot water heating tube 6. Therefore, not only can the heat conduction efficiency be greatly increased, but also the strength of the pipe-shaped hot water heating tube 6 can be increased to minimize the thermal deformation of the hot water heating tube 6 due to the heat generated by the electric heater 7. it can.
Moreover, it is desirable to install a muffler cover 16 having a bubble locking projection 16a at the end at one end of the hot water heating tube 6.

  If the silencer cover 16 having the bubble locking projections 16a formed at one end of the hot water heating tube 6 is installed in this way, a small amount of the water inside the hot water heating tube 6 as shown in FIG. When water is instantaneously vaporized by an electric heater 7 installed outside the hot water heating pipe 6, bubbles generated inside the hot water heating pipe 6 are discharged at a time, but one end of the hot water heating pipe 6 is not broken. Since it tears while being discharged little by little on the bubble locking projection 16a of the silencing cover 16 installed in the noise, the noise caused by the generation of bubbles, that is, the noise of boiling water can be greatly reduced.

In addition, on the upper inner side surface of the high-temperature space 4 provided in the hot water heating tub 2, a round type or inclined surface form for guiding bubbles generated inside the hot water heating pipe 6 to the upper part of the discharge space 3. It is desirable to form the bubble guiding wall surface 4a.
If the bubble guiding wall surface 4a is formed on the upper inner surface of the high-temperature space 4 provided in the hot water heating tub 2 in this way, the hot water heating tube 6 was inside as shown in FIG. A small amount of water is instantaneously vaporized by the electric heater 7 installed outside the hot water heating pipe 6 and discharged through one end of the hot water heating pipe 6. At this time, the bubbles rise at a time without tearing and tear while slowly rising along the bubble guiding wall surface 4a, so that noise caused by the generation of bubbles, that is, noise of boiling water can be greatly reduced.

Various known electric heaters can be used as the electric heater 7 installed outside the hot water heating pipe 6. Among them, a PTC (Positive) that can reduce the amount of water in the hot water heating pipe 6 instantaneously because the installation space is small in order to make the hot water boiler slim and at the same time a very high output is obtained compared with a small electric heating area. It is desirable to use a Temperature Coefficient (Thermistor) thermistor.
The hot water storage tank 10 is connected to the hot water heating tank 2 and stores the hot water discharged from the hot water heating tank 2, and a water replenishing port 11 that is opened and closed by a plug 12 is formed on one external side. A hot water inflow end 13 connected to the hot water discharge end 8 of the hot water heating tank 2 and a hot water supply end 14 connected to the hot water mat are formed on the side, and a water shortage detection sensor 15 is installed inside.

The plug 12 for opening and closing the water replenishing port 11 of the hot water storage tank 10 is coupled in a threaded manner through a sealing packing, or is firmly coupled by a locking projection and a locking groove or the like. It is desirable to configure as follows.
An air discharge port 12a for discharging air and water vapor inside the hot water storage tank 10 can be formed inside the plug 12, and at this time, the air of the plug 12 is provided inside the hot water storage tank 10. It is desirable to install a U-shaped air discharge tube 17 connected to the discharge port 12a.
If the U-shaped air discharge tube 17 connected to the air discharge port 12a of the plug 12 is installed in the hot water storage tank 10 in this way, the hot water storage tank 10 can be plugged even if the hot water is fully filled. The hot water stored in the hot water storage tank 10 through the 12 air discharge ports 12 a is not discharged, and only the air and water vapor inside the hot water storage tank 10 can be easily discharged to the outside of the hot water storage tank 10.
Moreover, it is desirable to form the auxiliary space 18 at a position higher than the water replenishment port 11 in the upper part of the hot water storage tank 10.

  If the auxiliary space portion 18 is formed at the upper part of the hot water storage tank 10 so as to be positioned higher than the water replenishment port 11, the hot water is filled in the hot water storage tank 10 as shown in FIG. When the hot water hose of the hot water mat is pushed or the connecting hose is broken, the hot water stored in the hot water storage rod 10 cannot be discharged to the hot water mat side and is discharged by the hot water heating rod 2. When the heated water flows into the hot water storage tank 10, the auxiliary space 18 positioned higher than the water replenishment port 11 has a sufficient amount of hot water discharged from the hot water heating tank 2 as shown in FIG. Therefore, it is possible to prevent water leakage from occurring in the gap between the water replenishment port 11 and the stopper 12 when the hot water storage tank 10 is overfilled.

The water shortage detection sensor 15 installed in the hot water storage tank 10 is for detecting the water level inside, and is a well-known float type water level detection sensor or electronic device normally used in a conventional humidifier or aquarium. Although a water level detection sensor can be used, it is less bulky than a large float type water level detection sensor and requires less installation space to be easily installed inside the hot water storage tank 10 which is narrower due to slimming of the hot water boiler. It is desirable to use a small electronic water level detection sensor.
The discharge check valve 13 a is installed at the hot water inflow end 13 of the hot water storage tank 10, and the hot water generated by the hot water heating tank 2 is moved to the hot water storage tank 10, but the hot water stored in the hot water storage tank 10 is used. Has a role of preventing back flow to the hot water heating tank 2.

On the other hand, the electric circuit of the hot water boiler for hot water mats according to the present invention is provided with a heater overheat prevention sensor and a fall detection sensor. The heater overheat prevention sensor is a bimetal type sensor that automatically cuts off the power supply when the electric heater overheats, and the fall detection sensor is a sensor for cutting off the power supply when the hot water boiler falls.
The control board has a water level detection sensor 3a and an electric heater 7 installed in the hot water heating tank 2, a water shortage detection sensor 15 installed in the hot water storage tank 10, and a low water level detection of the hot water storage tank 10. A water shortage warning lamp that is sometimes lit, and a temperature sensor for preventing overheating attached to the outer upper part of the hot water heater 2 are connected.

The operation of the hot water boiler for hot water mats according to the present invention will be described below.
The hot water boiler for hot water mats according to the present invention is used in a state of being connected to the hot water mat 20 using a pair of connecting hoses 21 and 22 as shown in FIG.
If the hot water boiler 1 is connected to the hot water mat 20 by the pair of connecting hoses 21 and 22 and the power switch of the hot water boiler 1 is turned on, the water shortage warning light is initially lit because there is no water inside the hot water boiler 1. The
In order to inject water into the hot water boiler 1, as shown in FIG. 7, the connection hose 22 connected to the hot water supply end 14 formed on the lower surface of the hot water storage tank 10 is separated and then separated. Water is injected into the hot water mat 20 and the hot water boiler 1 through the end of the connecting hose 22. As a device for injecting water into the connection hose 22, it is desirable to use an existing manual water pump or a specially manufactured water injection device.

When water is injected through the connecting hose 22 separated from the hot water supply end 14 of the hot water storage tank 10, the injected water fills the hot water hose installed inside the hot water mat 20 with full water, and then the hot water heating tank 2 The hot water recovery end 9 flows into the hot water heating tub 2 so that the hot water heating tub 2 is filled with water.
Subsequently, the connecting hose 22 separated from the hot water supply end 14 of the hot water storage tank 10 is connected again to open the plug 12 fastened to the water replenishment port 11 formed at the upper part of the hot water storage tank 10, and then the hot water Water is poured into the storage tank 10 to a certain water level. After confirming that the water shortage warning light is extinguished, the water injection operation for the hot water boiler 1 is completed by fastening the stopper 12 of the water replenishing port 11.

After the water injection operation for the hot water boiler 1 and the hot water mat 20 is completed, the water inside the hot water heating pipe 6 connecting the high temperature space 4 and the low temperature space 5 of the hot water heating tank 2 is heated by the hot water heating pipe 6. It is heated by the electric heater 7 installed outside.
As shown in FIG. 8, a small amount of water inside the hot water heating pipe 6 is instantly vaporized and the internal pressure of the hot water heating bowl 2 increases. If the internal pressure of the hot water heating bowl 2 increases in this way, A small amount of hot water generated in the hot water heating tank 2 by the vapor pressure opens the discharge check valve 13 a through the hot water discharge end 8 and is discharged into the hot water storage tank 10.

Subsequently, after a small amount of hot water generated in the hot water heating tank 2 is discharged to the hot water discharge end 8, the power supplied to the electric heater 7 is automatically shut off, whereby the operation of the electric heater 7 is performed. If interrupted, the water vapor generated inside the hot water heating tank 2 begins to liquefy. Therefore, the internal pressure of the hot water heating tub 2 is suddenly lowered to form a vacuum state. If a vacuum state is formed inside the hot water heating bowl 2, a suction force is generated by this vacuum state, so that a small amount of hot water inside the hot water mat 20 is heated in the hot water heating bowl 2 as shown in FIG. It is sucked into the hot water heating tank 2 through the collection end 9.
If a vacuum state is formed inside the hot water heating tank 2, the discharge check valve 13a is more firmly closed by the vacuum suction and the flow path of the hot water discharge end 8 is shut off. The warm water stored inside 10 is completely sucked into the warm water heating tank 2.

In this way, a small amount of warm water in the warm water mat 20 is sucked into the warm water heating bowl 2 by the vacuum suction formed in the warm water heating bowl 2, and thereby chained into the warm water mat 20. A vacuum state is also formed. If a vacuum state is formed in the hot water mat 20, suction is generated by the vacuum state, and a small amount of hot water stored in the hot water storage tank 10 as shown in FIG. 14, the water is sucked into the hot water mat 20 and the hot water circulates.
If the hot water in the hot water mat 20 is sucked into the hot water heating rod 2 by the vacuum suction input formed in the hot water heating rod 2, the electric heater installed outside the hot water heating tube 6 by the control board 7 is supplied with power, the electric heater 7 is activated again, and the hot water circulation process is continuously repeated in a short cycle.

In the hot water boiler for hot water mats according to the present invention, it is desirable to set the circulation cycle to about 2 to 3 seconds by setting the circulation amount of the hot water heating tank 2 to about 10 to 30 ml in consideration of electricity charges and the like.
The hot water boiler for hot water mats according to the present invention includes a high temperature space portion 4 and a low temperature space portion 5 located on the left and right sides of a recessed groove portion 2a formed at the center lower portion of the hot water heating rod 2, and a high temperature space portion 4 and a low temperature space portion 5 respectively. The discharge space part 3 that connects the upper part of the hot water heating pipe 6 and the hot water heating pipe 6 that connects the lower part of the high temperature space part 4 and the low temperature space part 5 are formed in a “R” shape so as to form a circulation flow path. The hot water heating pipe 6 is installed at an inclination, and an electric heater 7 is installed on the outer surface of the hot water heating pipe 6. A small amount of water inside the hot water heating tank 2 is instantaneously vaporized using a hot water heating pipe 6 on which an electric heater 7 is installed on the outside. After moving a small amount of warm water to the warm water storage tank 10 by the vapor pressure, a small amount of warm water is sucked in by sucking a small amount of water inside the warm water mat by a vacuum suction formed inside the warm water heating tank 2. Can be continuously circulated in a short cycle. For this reason, the circulation efficiency of warm water can be greatly improved compared with the conventional warm water boiler which heats all the water in a warm water heating rod, and forms a vacuum suction.

  As mentioned above, although the preferable Example regarding this invention was described, this invention is not limited to the said embodiment, All the changes in the range which does not deviate from the technical field to which this invention belongs are included.
