[0041] The present invention will be described in detail below with reference to the accompanying drawings.

[0042] As shown in FIG. 1, the component of the electrothermal film quartz tube progressive type boiling boiling heater can be divided into three parts according to its function, and is described as follows. [0043] First, the heating portion.

[0044] As shown in FIG. 1, the heating part of the device consists of a boiling water tee (1), a boiling water pipe (2), a communication pipe (5), a cold water tee (6), an electrothermal film quartz heating pipe (7), The return valve (8) and the water inlet (13) inlet pipe (14) are combined. The cold water tee (6) is connected to the water supply main pipe (not shown), the cold water tee (6) receives water supply from the water supply pipe, and the drinking water enters the water inlet pipe (14) via the check back (8), and enters into The upper end of the water pipe (14) is connected to the lower port of the check valve (8), and the lower port of the electric heating film quartz heating pipe (7) of the S-shaped layout is connected in series by the connecting pipe (5), and the drinking water flows into the electric heating film quartz. After the heating tube (7), it receives the heating mode of the electric heating film quartz heating tube (7) "in the fire water", and is heated by the electric heating film quartz heating tube (7) in three stages. When the drinking water passes through the three-stage heating flow, it is S-shaped. When the upper port of the electrothermal film quartz heating tube (7) is laid out, the drinking water is already boiled, and the boiling water is boiled through the boiling water pipe (2) and the boiling water tee (1) from the hot water tap (not shown on the figure) .) shed.

[0045] Second, the face portion.

[0046] As shown in FIG. 1, the device of the control part is composed of a desuperheating pressure reducing valve (3), a thermostat (4), a check valve (8), a delay circuit board (11), and a delay switch (15). ) Joint composition.

[0047] The function of the dredging decompression tree (3) is that, when the drinking water is boiled and the delay circuit is still in the working state, the pressure generated by the electrothermal film quartz heating tube (7) the progressive heater It can be released through the dehydration pressure reducing valve (3) for the purpose of full heating.

[0048] In other words, if the machine is still in a heating condition and the user draws less than 350 ML, the user is allowed to turn off the tap to stop the water. This is because after the boiling water tap is closed, the dredging pressure reducing valve (3) starts to operate, and the pressure generated by the heating will open the valve ball (203) in the dredging pressure reducing valve (3) to discharge the high pressure gas and water. In the water supply pipe. The presence of the dredging and reducing pressure valve (3) allows the user to obtain the required amount of water to be used as desired, greatly improving the freedom of operation of the machine.

[0049] On the other hand, if the user needs to obtain a large amount of water, in this case, the user only needs to perform the easy operation of the repeated start delay switch (15) to 0K.

[0050] As shown in FIG. 2, the dredging pressure reducing valve (3) is composed of a three-way upper valve body (201), a ball seat (2Θ2), a valve ball (203), and a 锕 spring (204). The lower valve body (205) is composed, the upper valve body (201) and the lower valve body (205) are combined to form a valve body cavity, and the upper valve body (201) serves as a ball seat (202) of the valve ball (203), the valve A spring (204) presses the valve ball (203) over the valve seat (202).

[疏051] The dredging pressure reducing valve (3) is installed in parallel between the boiling water pipe (2) and the water supply pipe to guide the high-pressure water gas back into the water supply passage. The three-way upper valve body (201), that is, the upper port of the boiling water tee (1), is opposite to the boiling water pipe (2), and the other port of the three-way is connected to the boiling water tap. The lower end of the dredging pressure reducing valve (3) is connected to the upper valve body (301) of the three types in the check valve (8), that is, the cold water tee (6), and the water is boiled and delayed. When the circuit is still in operation and the boiling water tap is to be turned off, the high-pressure water generated by the electric heating film quartz heating tube (7) progressive heater will open the valve ball in the decanting pressure reducing valve (3) ( 203) Released for safe heating purposes.

[0052] As shown in FIG. 3, the check valve (8) is composed of a three-way upper valve body, a valve hole (102), a valve flap root (103), a valve valve (104), and a lower valve body ( 105) composition; the upper valve body (101) is coupled with the lower valve body (105) to form a valve cavity of the check valve (8>; the valve cavity is provided with a soft valve valve (1Ό4 >, the valve valve (104) and the valve flap root (103> are L-shaped, the valve valve (104) and the valve flap root (103) are integrally formed, and the valve stem root (103) is embedded in the upper valve body (101) a predetermined groove in the joint with the lower valve body (105); the check valve (8) is connected in series with the inlet pipe (14), and has the function of controlling the drinking water only to enter; Heating is achieved in an environment.

[0053] The thermostat (4) is connected in series on the neutral line of the main circuit, and is disposed at the boiling water outlet port of the electrothermal film quartz heating tube (7> which is connected in an S-type; the thermostat ( 4), set the breaking temperature to be] When the surface temperature of the electrothermal film quartz heating tube (7) exceeds 1Ό5Ό or the machine is dry, the bimetal in the thermostat (4) is separated due to the difference in thermal expansion coefficient. , will automatically cut off the circuit to protect the safe operation of the machine.

[0054] As shown in FIG. 4, the functions and principles of the delay switch (15) and the delay circuit board (11) are as follows: When the machine is in the standby state, the drink machine is connected to the power source, and the 220V power supply is via Dl- D4 rectification, R2 voltage limiting current limit, C 3 filtering, get DC working voltage. Then, after R4 current limit, VT1 is turned on by the base bias current, and the trigger current of the unidirectional thyristor SCR is shorted to ground by VT1. Since the main circuit is in the off state, the main circuit is in the off state, and the machine does not work. When the drinking machine is heated, while the delay switch (15) is pressed, the electrolytic capacitor C 2 is charged, and VT2 is turned on by the base bias current, and the base bias current of VT1 is short-circuited to the ground by VT2. VT1 is turned off due to the loss of the base bias current. The SCR trigger terminal is turned on and the drinker starts to work. When the delay switch (15) is released, the base bias current of VT2 is turned off again, but At this time, due to the presence of the charging voltage on C 2 , the base bias current of VT2 can still be maintained through R5, VT2 is turned on, VT1 is turned off, SCR continues to be turned on, and the drinking machine is constantly operated, when the charging voltage is on C 2 After the release is completed, when VT2 has no base bias current and is turned off, T21 is turned on, and the SCR turns off the main circuit and stops.

[0055] The delay circuit board (11) of the delay switch circuit is installed in a special mounting groove below the protection box (9) to avoid the influence of high temperature on the circuit.

[0056] Further, the delay time of the delay switch circuit is 60 seconds. During this period, the boiling water output of the drinker is not less than: 350ML. However, the amount of water used by the user may not be exactly 350ML. When the dosage is less than 350ML, the user can turn off the boiling water tap. The dredging pressure reducing valve (3) installed in the machine will start itself after turning off the boiling water tap. Drain into the water supply pipe of the drinker. In this way, although the machine worked for a few seconds, it was replaced by the safe operation of the drinker and the convenience of the user.

[0057] In another case, if a group of guests or the amount of thunder will be greater than 350ML, the drinker will work for 60 seconds. Automatic stop, in this case, the tenant only needs to do another easy time to start the delay switch (15).

[0058] Third, the protection and installation part.
