Description

201248094 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a heating device, and more particularly to a safety, anti-shock heating device that conducts heat by gas to heat water. [Prior Art] [0002] In this urbanized society, many people go back home after a busy day's work. One of the most anticipated things is to take a comfortable hot bath and wash the dust and dirt on the body. To eliminate fatigue and relax the body and mind, however, the conventional electric water heaters, especially the instant electric water heaters installed in the bathroom, are powered by electric heating units that directly heat the water, because only pure water is bad. Electrical conductors, general bath water is not pure water, and still has conductive characteristics. Therefore, such electric water heaters usually have a leakage protection device installed to avoid the risk of electric shock to the user, but the heating method is still substantially There is a concern that electric shock causes the user to be at risk of electric shock while using it, and there is a safety problem. [0003] The main purpose of the present invention is to solve the problem that the electric water heater has an electric shock. The security concerns caused by doubts. [0004] In order to achieve the above object, the present invention provides an anti-electric shock gas-conducting water heater, which uses a plurality of small thermal bubbles to heat a water body in a water tank, which comprises a gas transmission unit, a heating temperature control unit, and a plurality of pores. Exhaust unit. [0005] The gas transmission unit has an air inlet that collects gas after inhaling the surrounding gas, and sends the gas; the heating temperature control unit and the gas transmission 100118661 Form No. A0101 Page 4 / Total 20 pages 1002031485- 0 201248094 The unit is connected and heats the gas sent by the gas transmission unit to form a hot gas, which is sent out; the exhaust unit is placed in the pool, and the exhaust unit is connected to the heating temperature control unit through a conveying pipe, and the electric energy is then The form of hot gas is discharged into the body of water by the exhaust unit to heat the body of water. [0006] The exhaust unit has a plurality of fine pores, so that a large amount of dense small thermal bubbles are formed when the hot gas is discharged in the water body, and the buoyancy is small, the time spent in the water body is long, and a large amount is small. The area in which the hot bubbles are in contact with the water body is large, so that the heat energy in the hot gas can be efficiently transferred into the water body. The design of this effective heating water body can be seen in the following theoretical calculations. [0007] It is well known that heat transfer efficiency is proportional to the thermal contact area. Suppose that the radius of a large spherical hot bubble in a water body is the corresponding table.

D area S is b [0008] S = 4 π ru2(l) b b [0009] volume is b

[0010] V = 4; rru3/3 (2) bb [0011] Now, the same volume of hot gas is split into N small thermal bubbles by using fine pores, and the radius of each small thermal bubble is assumed to be r. , then all small

SS 100118661 Form No. 1010101 Page 5 of 20 1002031485-0 201248094 [0015] From (1), (3), the ratio of the area to be heated to all small thermal bubbles and the area of contact with a single large bubble [0016] Ss/Sb = N(rs/rb)2(5) [0017] However, the total volume of all the small thermal bubbles is obtained by dividing the equal volume of large bubbles through the pores, so (2), (4) Equivalent [0018] N4^rs3/3 = 4; rrb3/3 (6) [0019] In other words: [0020] rs/rb= (1/Ν) 1/3(7) [0021] will (7) Substituting (5) to obtain the ratio of the total heating area of small bubbles and large bubbles [0022] Sg/Sb= N1/3(8) [0023] The formula (4) fully proves that small thermal bubbles can increase the area of the twisted area. And effectively heat the water body. For example, if a large thermal bubble is first divided into one million small thermal bubbles through a plurality of pores, and then these small thermal bubbles are sprayed into the water body, according to the formula, the heating surface of the water body is hoarded by the gas. It can be increased by (1, 〇〇〇, 000) 1/3 = 100 times, so the heating efficiency can be increased by a hundred times. In general, it is not difficult to make these holes in the exhaust unit, for example, with the now popular laser micro-drilling technology. [0024] As mentioned before, there is another technical advancement in reducing the volume of hot bubbles released from the exhaust unit: increasing the time during which the hot bubbles are in contact with the water body to increase the efficiency of heating the hot gas to the water body. Because the small thermal bubble has less buoyancy in the water, the time spent in the water is more than 100118661 Form No. 1010101 Page 6 / Total 20 Page 1002031485-0 201248094 [0025] [0026] G [0027] ❹ [0028 ] Long. According to Archimedes' theory, the buoyancy FD obtained by an object is equal to

D The weight of the liquid discharged. That is, the buoyancy of the bubble in the body of water is equal to the weight of the body of the bubble: FB = pVg (9) where V is the volume of the bubble, P is the density of the body of water, and g is the acceleration of gravity. Therefore, it can be clearly seen from the formula (9) that the rising acceleration of the bubble in the water body (proportional to the buoyancy FB) is proportional to its volume; in other words, the residence time of the small thermal bubble in the water body is better. Long, the heat energy stored in the gas can be transferred to the water body more effectively. In addition, the exhaust unit further includes an accommodating space and a heat conducting structure, the heat conducting structure has opposite sides, one side is in contact with the accommodating space, and the other side is in contact with the water body in the pool, the conveying pipe The hot gas is transported to the accommodating space, and the thermal energy of the hot gas is quickly transferred to the water body via the heat conducting structure, and the residual heat in the hot gas is continuously discharged to the small hot air bubble through the plurality of pores on the exhaust unit to In the water. Further, when the gas is sucked by the gas transfer unit and heated by the heating temperature control unit to form the hot gas and fed into the exhaust unit, the heat conducting structure is first contacted, and the specific heat of the heat conducting structure is smaller than that of the water body. Therefore, the heat conducting structure can absorb the thermal energy of the hot gas quickly, and transfer the heat energy to the heat conducting structure, and then transfer the absorbed heat energy to the water body in the pool, since the heat conducting structure does not rise like the hot gas. Outside the pool, it is possible to heat the water for a longer period of time. Therefore, according to the above concept, the present invention uses an exhaust unit having a fine hole to produce 100118661. Form No. A0101 Page 7 / Total 20 pages 1002031485-0 201248094 A plurality of small thermal bubbles are generated by electrically insulating gas and safely transmitting electric energy. A body of water, at the same time, the hot gas transfers part of the heat energy to the water body, and the tiny heat bubbles generated can be used to form ultrasonic waves in the water to help clean and massage the user in the water body, and to achieve a clean and massage pressure of the heated water body. The effect.
