[Technical field to which the new model belongs] This case prevents the empty burning structure of the heating device of the water storage type electric water heater (1), which is related to the heating device of the general water storage type electric water heater. More specifically, it is Regarding the electric heating tube in the heating device of the water storage type electric water heater, when an abnormality occurs, how to make it can immediately turn off the power and trip to achieve the safety creation of the structural creation. 2. [Previous technology] According to the water heater is necessary for today's homes, the current general water heaters can be divided into two types: petroleum gas heating and electric heating due to different heating sources. However, the former is dangerous because of the leakage of petroleum gas. Electric heating is safe. As for the heating device 3 currently installed on the position hole 2 1 1 at the peripheral edge of the bottom section of the water storage bucket 21 of the water storage type electric water heater 2, please refer to the first and second pictures, which are mainly composed of: The front section is provided with an electric heating tube 3 1 1, and the electric heating tube 3 1 1 can be extended into the internal storage tank 2 1, and the peripheral edge a of the final section is provided with a threaded section 3 1 2 electric heating tube fixing seat 3 1. One is hollow. It can be inserted through the hole 2 1 1 set in the bottom section of the bucket 2 1 and welded to the peripheral edge of the positioning hole 2 1 1 by the flange 3 2 1 provided on the outer peripheral edge, and the inner bottom end is facing A positioning flange 3 2 2 is set in the center, and a water stop washer 3 2 3 is sleeved on the positioning flange 3 2 2. The inner and outer peripheral edges of the positioning flange 3 2 4 are combined with a seat 3 2 4. A wire and an electric heating pipe are provided. The electric heating pipe 3 1 1 of the fixed seat 3 1 is connected and fixed on the surface of the inner bucket 2 1 as the water bucket 2 1 The temperature of the water stored in the bucket is transmitted through the wall of the bucket to sense the internal temperature. It has not been used for a period of time, but when it is lowered to a set temperature of 5 M273698 degrees, '俾 controls the electric heating tube 3 1 1 as a temperature control switch 3 3 (for the conventional structure, Therefore, its structure will not be described in detail), Jiyi and the temperature control switch 33 are also connected by wires, and when the temperature control switch 3 3 and the electric heating pipe 3 1 1 are connected to the wire and other lines because of covered wires, and made of insulating materials When the skin is damaged and a leakage occurs, the leakage circuit breaker 3 4 (also a known component, so its structure is not described in detail) can be cut off. Finally, the electric heating pipe is fixed to the seat 3 1 and the front section of the electric heating pipe 3 1; [Through the combined seat 3 2 and penetrate deep into the water storage tank 21 'by screw thread section 312 and threaded section 324 of the combined seat 32 and screw together' and abut the sleeve on the inner bottom end of the combined sleeve 32 on the positioning flange 322 The water washer 3 2 3 is screwed with the combined seat 32 to form a heating device 3 of a water storage type electric water heater under the leak stop. With the above composition, when the cold water enters the bottom end of the water storage bucket 21 through the water inlet pipe 2 1 2 and a check valve 2121 is provided at the water inlet pipe 2 1 2 into the water storage bucket 21 (this is a general conventional device, and is not the case) (Creative focus, so I won't go into details) '俾 Prevent the loss of water flow from the water storage tank 21 to the water tower (not shown) when the water is stopped, and then fill it with water storage. The electric heating pipe 311 penetrates deep inside the bottom section of the water storage bucket 21, and the surface of the electric heating pipe 3 1 1 directly contacts the stored water, heat-conducts and heats the stored water, and finally, based on the principle of heat rise, the heated hot water is provided from the outlet to the stored water. The hot water output pipe 213 in the top section of the bucket 21 outputs the use effect. However, the water storage bucket 2 1 of the general water storage electric water heater 2 has a water inlet pipe 2 1 2 which is located at the inner bottom end of the water storage bucket 2 1 and has an electric heating pipe fixing base 3 1 for the heating device 3 in front. 1 1 below, so that when installing 6 M273698 water storage electric water heater, if the installer initially enters the water storage tank from the water inlet pipe 2 1.2 in the cold water 2 1 internal bottom end, and the water level has not exceeded and flooded the electric heating pipe 3 1 1 times That is to say, the power is transmitted in a wrong way, and the improper start-up will cause the electric heating tube 3 1 1 to be heated and then immersed in water, which will inevitably cause quenching and easy damage, which will affect the life. In addition, taking the domestic example as an example, the uncertain weather in recent years has caused limited water supply to occur when the water supply has become more severe, and the water company has not even warned that the water will be shut down. In addition, it is located in the water inlet pipe 2 1 1If you want to enter the water storage bucket 2 1 check valve 2121 at Φ, if there is no water stop, the water flow in the water tower can also enter the water storage bucket 21 normally according to the needs, so the water flow should be prevented from flowing back to the water tower's check valve. 2 1 2 1. It does not cause the so-called water flow back to the water tower, but when it is used for a period of time, it will not know or pay attention to the deterioration of the structure or material, so when it encounters a water stop, add If the upper check valve 2 1 2 1 is just damaged, it will cause the water flow originally stored in the water storage bucket 2 1 to return to the water tower, resulting in no water in the water storage bucket 2 1 and the temperature in the water storage bucket 21 will decrease, which will provide As a temperature control switch 3 3 that senses the temperature of water stored in the bucket 2 _ 1 and is fixed to the wall of the bucket (this is a general custom structure and is not the focus of this case, so I wo n’t go into details), so the sensor inside the bucket 21 is sensed. The temperature should be lower than the setting of the electric heating tube 311 The heating temperature 'makes the electric heating tube 3 1 1 to start heating, that is, the water storage bucket 21 is completely submerged, but the electric heating tube 311 continues to heat " air burning, which seriously affects its service life, and even becomes dangerous. Situation, and urgently need improvement. In addition, the beauty that the water storage electric water heater originally intended to improve the danger of leaking the water heater heated by petroleum gas is greatly affected, and its electric heating pipe 3] M273698 is often used in the process, because of " quenching or emptying When burnt and damaged, in addition to the inconvenience of having to ask a maintenance operator to replace it for maintenance, the user must again bear the parts and maintenance costs required for replacing the electric heating pipe, which needs to be urgently improved. III. [New content] It is based on 'the creator has devoted himself to the lack of effective improvement in the use of electric water heaters for electric water heater heating methods, and cooperates with its manufacturing experience and painstaking research results. Finally, develop and produce this creative content, and then file a patent application. The main purpose of this creation is to provide a structure for preventing the empty burning of the heating device of the water storage type electric water heater (1), which is an electric heating pipe fixing seat that can be extended into the water storage barrel by the electric heating pipe provided in the previous section, and the electric heating pipe fixing is provided The seat cover is locked and locked, and the combination seat is welded on the periphery of the set hole set at the bottom end of the water storage barrel. It is characterized in that the end of the electric heating tube provided in the front section of the general electric heating tube fixing seat is bent toward the electric heating tube fixing seat. Fold it, and make its end contact the top surface of the electric heating tube fixing base, and cooperate with a _ a temperature sensor at the opposite position on the back of the electric heating tube fixing base, so that when the electric heating tube has an air burning phenomenon, the heat energy emitted by the electric heating tube , It can be instantly transmitted to the temperature sensor through its end contacting the top surface of the heating tube fixing seat, so that the temperature sensor is disconnected due to the abnormal high temperature, so that the current can no longer enter the heating tube, and the heating is stopped. Tube heating 'achieves the effect of protecting the electric heating tube from air burning and overall safety. Fourth, [Implementation] For the remainder, I would like to describe the structural characteristics and operation of the creation in this case. I will describe it in the form of matching illustrations, and I will provide a review for reference. M273698 First of all, this creation is a heating device 4 installed on the water storage bucket 2 1 of the water storage electric water heater 2 • The hole 4 on the peripheral edge of the bottom section 2 1 1 Please refer to Figures 3, 2 -A and 4 As shown in Figure 4A, it is still mainly caused by:-an electric heating pipe 4 1 1 is provided in the front section, and the electric heating pipe 4 1 1 can be extended into the interior of the water storage bucket 2 1; The electric heating pipe fixing seat 41 with a threaded section 4 1 2 is a hollow perforation, and can be inserted from the position hole 2 1 1 set at the peripheral edge of the bottom section of the water storage barrel 21, and welded by the flange 4 2 1 set at the outer peripheral edge. At the peripheral edge of the positioning hole 21, a positioning lu dog edge (not shown) is provided toward the center of the positioning hole, and a stop ring 4 2 3 is placed on the positioning flange, and a thread segment 4 is provided on the inner outer periphery. 2 4 of the combined seat 4 2. A wire connected to the electric heating pipe 411 and attached to the surface of the inner bucket 21 of the water storage bucket 21 as a water storage bucket 2 1 The temperature of the internal water storage temperature is transmitted through the wall of the bucket to sense the temperature inside the barrel 4 3 (It is a conventional structure, so its structure will not be described in detail), and a leakage circuit breaker 44 which is also connected to the temperature control switch 43 by a wire (also a conventional component). The structure is not described in detail). Finally, the electric heating pipe fixing seat 4 1 is passed through the combined seat 4 2 and penetrates into the inner part of the water storage bucket 2 1 through the combined seat 4 2, and the threaded section 41 2 and the threaded section 424 of the combined seat 42 are used. It is screwed together, and abuts against the water-stopping complete circle 4 2 3 on the positioning flange on the inner bottom end of the combined seat 32, so that it can be screwed together with the combined seat 42 to form a heating device 4 for a water storage type electric water heater under the leakage. The main feature of this case is that the end 4111 of the electric heating pipe 411 provided in the front section of the electric heating pipe fixing seat 41 is changed to the electric heating pipe fixing seat 4 1 and the end 4 1 1 1 and the electric heating pipe fixing seat 4 1 are bent. The surface 413 is in contact (as shown in the fourth picture and the fourth picture-A), and a temperature sensor 5 is provided at a position opposite to the rear side of the electric heating tube fixing seat 41 in cooperation with M273698 (a known component, so its structure will not be described in detail) ), So that when the electric heating tube 4 1 1 has an air burn phenomenon, the heat energy emitted by the electric heating tube 4 1 1 can be instantly transmitted to the temperature sense through the end 4111 of the electric tube 4 11 and the top surface 4 1 3 of the electric heating tube fixing seat 41. The temperature sensor 5 is disconnected due to the abnormally high temperature, so that the current can no longer flow into the electric heating tube 4 1 1 'to stop the heating of the electric heating tube 4 1 1 to protect the electric heating tube 4 11 from being empty. Effect of burning and overall safety. With the above structure, when the water storage bucket 2 1 of the water storage type electric water heater 2 has no storage water for some reason, the temperature control switch 4 3 fixed on the wall of the water storage bucket 2 1 is sensed by the sensor. The temperature of the barrel wall is lower than the heating temperature set by the electric heating tube 411, and when the electric heating tube 4 1 1 is to be heated, the air heating phenomenon occurs due to the instantaneous high temperature generated by the entire electric heating tube 41 i. The thermal energy emitted by 4 1 1 can be instantly transmitted to the temperature sensor 5 through its end 4111 in contact with the top surface 41 of the electric heating tube fixing seat 41, and the temperature sensor 5 is disconnected due to the abnormally high temperature. 'The current can no longer be fed into the electric heating tube 4 1 1 and the heating of the electric heating tube 4 1 1 is stopped to achieve the effects of protecting the electric heating tube 41 from being burnt out and overall safety. In addition, as shown in the fifth figure, a perforation 4 1 4 can also be provided in the electric heat pipe fixing base 4 1, and a sealing can be fixed from the perforation 414 between the power supply heat pipe fixing base 411 and the electric heating pipe 411 provided in the previous section. Sleeve 415, and the outer surface of the sleeve 415 is in contact with the surface of the electric heating tube 41 1 and a sleeve 4 1 5 is covered with a thermal fuse 4 1 M273698 6 from the electric heating tube fixing seat 4 1 4 1 4 extends into the sleeve 4 1 5 • In the same way as the water storage bucket 2 1 of the water storage electric water heater 2, if for any reason there is no water stored in it, it will be fixed on the wall of the water storage bucket 2 1 Temperature control switch 4 3 Because the temperature of the barrel wall is lower than the heating temperature set by the electric heating tube 4 1 1, when the electric heating tube 4 1 1 is heated, the entire electric heating tube 4 1 1 is instantaneous. The generated high temperature is immediately set by the perforation 4 1 4 provided in the center of the electric heating pipe fixing seat 4 1, and the temperature within the closed sleeve 414 φ fixed between the electric heating pipe fixing seat 41 and the front electric heating pipe 411 The fuse 4 1 6 detects the abnormally high temperature of the surrounding electric heating tube 4 1 1 and opens the circuit. The 'but may achieve the same effect without burning air heating pipe protection and safety of the whole. The above-mentioned original creation can solve the shortcomings of conventional products of the same kind, and its effects and advantages are significant. It has never been disclosed in the market publications. The rationale for the establishment of the new model is very clear. V.
