断線などの故障に至る恐れがある。2. Description of the Related Art A conventional general steam generator has a configuration in which water is heated by an electric heater such as a sheath heater to generate steam. However, when the electric heater is used, if the heat release from the electric heater deteriorates or an excessive current is supplied, the heater itself may be overheated to cause a failure such as disconnection.

加熱する構成となっている。[0003] In order to solve such a drawback of heating by a conventional electric heater, a steam generator using induction heating has been proposed. For example, JP-A-9-2691
In the steam generator described in No. 01, a coil is wound around the outer peripheral wall of a cylindrical water tank for storing water, and the water in the water tank is heated by induction heating a heating element provided inside the water tank. It has a configuration.

Have been. A water supply pipe is connected to the bottom end surface of the water tank, while a water vapor delivery pipe is connected directly above the heating element. When water is stored in the water tank to the position where the lower part of the heating element is immersed, and a heating current is supplied to the coil, the heating element is induction-heated, and the water is heated by heat exchange with the heating element to become steam. When the water vapor rises while passing through the gap of the heating element, it is further heated to high temperature steam (so-called dry steam containing no water droplets), which is taken out through the delivery pipe.

Many of the water droplets come into contact with the heating element exposed on the water surface and become water vapor, but a part of the water droplets may jump into the delivery pipe as water droplets without being converted to water vapor and be sent out together with the water vapor.

When a high-frequency current is applied to the coil, Joule heat is generated in the heating element, and water in contact with the heating element is heated and turned into steam. The generated steam rises and is taken out from the steam delivery pipe. Water in the evaporation chamber boils, and water droplets scatter from the water surface immediately above the heating element, but since there is no inlet for the steam discharge pipe above it, water droplets may jump into the steam discharge pipe.

Further, the heat of the heating element is reliably transmitted to the water and is used for heating the water, so that the heating efficiency is high. Furthermore, since the evaporating chamber and the water storage chamber are separated, the amount of water stored in the evaporating chamber can be small, the temperature can be raised quickly, and steam can be generated immediately after the operation starts. .

る。FIG. 2 is a configuration diagram of a steam generation system using the steam generator 1 having the configuration shown in FIG. A water supply pipe 2 having one end connected to the bottom of the steam generator 1 and the other end connected to a faucet (not shown) has an electromagnetic valve 3 and a three-way valve 4.
Is provided. The other end of the three-way valve 4 is connected to a drain pipe 5 reaching a drain port. The coil 17 of the steam generator 1 is connected to a high frequency power supply 6 for supplying a high frequency current. A detection signal of the water level sensor 9 including the first to third electrode rods 211 to 213 is input to the control unit 7, and an operation signal is also input from the operation unit 8. The control unit 7 mainly includes a CPU and the like, and controls operations of the electromagnetic valve 3, the three-way valve 4, the high-frequency power supply 6, and the like.

The control unit 7 supplies water to the container 11 by opening the electromagnetic valve 3 and flowing the water supply pipe 2 through the three-way valve 4. Since the water storage chamber 14 and the evaporating chamber 15 communicate with each other via the water passage 13, the water levels in both chambers rise almost identically. The water level rises to the maximum water level L3 and the third electrode rod 2
When the tip of 13 is immersed in water, conduction between reference electrode 22 and third electrode rod 213 is established. When the control unit 7 detects this conduction, it closes the electromagnetic valve 3 and stops water supply.

へと取り出される。When steam generation is instructed by the operation unit 8,
The control unit 7 drives the high-frequency power supply 6 to start supplying current to the coil 17. When a high-frequency current flows through the coil 17, a magnetic flux is generated that passes vertically through the internal space of the heating element 16,
A current is induced in the heating element 16 by the magnetic flux. As a result, Joule heat is generated, and the water stored in the evaporation chamber 15 is heated. The evaporating chamber 15 is a narrow space sandwiched between the inner wall of the container 11 and the partition 12, and the amount of water stored therein is small. Into steam. The water vapor rises and flows into the water storage chamber 14 and accumulates in the upper space.
Then, it is taken out from the inlet 19a to the outside via the steam delivery pipe 19.

り、水との熱交換により効率的に水を加熱する。When water evaporates and the water level in the evaporating chamber 15 is going to drop, cool water flows in from the water storage chamber 14 through the water passage 13 and the water levels in both chambers are maintained substantially the same. When the water level in the water storage chamber 14 falls and becomes lower than the reference water level L2, the tip of the second electrode rod 212 is exposed on the water surface, and the connection between the reference electrode 22 and the second electrode rod 212 becomes non-conductive. When detecting this, the controller 7 determines that the water level has dropped too much, opens the electromagnetic valve 3 and starts water supply again. Then, the water supply is continued until the state between the reference electrode 22 and the third electrode rod 213 changes from the non-conductive state to the conductive state, and the electromagnetic valve 3 is closed. By repeatedly performing such control, the water level in the water storage chamber 14 becomes equal to the reference water level L2.
And the maximum water level L3. Therefore,
The entire heating element 16 is always immersed in water, and efficiently heats water by heat exchange with water.

The tip of the electrode rod 211 is exposed on the water surface. If the water level continues to decrease in this state, the heating element 16 is exposed above the water surface, the temperature of the heating element 16 itself rises excessively, and when the container 11 is made of resin, it may be melted. Therefore, when the electrical connection between the first electrode bar 211 and the reference electrode 22 becomes non-conductive, the control unit 7 determines that the water level has dropped too low, and controls the high-frequency power source 6 to stop supplying current to the coil 17. . This stops the heating.

出すことができる。In the steam generator 1 of this embodiment, the water storage chamber 14
Although the water stored therein is slightly heated by heat conduction or the like through the partition 12, the heat capacity inside the water storage chamber 14 is large, and cold water is supplied from the water supply pipe 2 as the water level decreases. The temperature rise is small. On the other hand, the amount of water stored in the evaporation chamber 15 is small, and
6, the temperature rises rapidly during heating, and the water boils violently. Therefore, although the water surface in the evaporation chamber 15 fluctuates greatly due to boiling, the water surface in the water storage chamber 14 has almost no undulation. Therefore, the first
The water level can be detected very accurately by the third electrode rods 211 to 213. That is, since the interval between the reference water level L2 and the maximum water level L3 can be narrowed, the water supply is not wasted. Further, fine water droplets scattered when boiling violently in the evaporation chamber 15 are blocked by the partition wall 12, and even if the water drops into the water storage chamber 14 via the upper space, the position of the inlet 19a is low and the water inlet 19a is lowered. Since it is oriented, it does not enter the inlet 19a. Therefore, only steam can be reliably taken out from the steam delivery pipe 19.

なる。In the steam generator 1 having the above-described structure, if the steam generator 1 is used for a long time, the concentration of the impurity component contained in the water in the container 11 increases, and the scale is easily deposited on the heating element 16. Therefore, it is preferable to drain the water in the container 11 when it has been used for a certain time or when it has not been used for a long time. Then, when an instruction to drain water is given from the operation unit 8, the control unit 7 controls the three-way valve 4 to connect the container 11 side to the drain pipe 5. Thereby, the water in the container 11 is discharged to the outside through the drain pipe 5, and the inside of the container 11 becomes empty.
