Osmotic pressure and dissolving power increase.

[0005] For this reason, when used for cooking, rice can be cooked plumply and deliciously, boiled food can be cooked softly without distorting, suitable for removing vegetables, tea and coffee It is known that there is an effect such as that it can be added deliciously.

Therefore, the present invention further extends the multifunctionality of a microwave oven, provides a new microwave oven capable of generating alkaline ionized water from tap water, well water, and the like, and is applicable to a conventional microwave oven.

FIG. 1 is a schematic structural view showing a first embodiment of a microwave oven according to the present invention. In FIG. 1, a rotating shaft 2 is provided on a bottom surface in a heating chamber 1, a jack 3 to which DC power is supplied is mounted on a ceiling, and a gas sensor 5 is mounted on an exhaust port 4.

A high frequency source 6 such as a magnetron for generating a microwave is installed outside the heating chamber 1, and the generated microwave is sent into the heating chamber 1 through a waveguide 7. Further, a cooling fan 8 for air-cooling the high frequency generation source 6 and a motor 9 for driving the rotating shaft 2 are provided outside the heating chamber 1.

Inside the heating chamber 1, a container body 10 is housed. As shown in FIG.
A projection hole 10a engageable with the rotating shaft 2 is provided on the bottom surface,
The lid 11 is covered on the upper surface. An electrode plate 12 for the anode and an electrode plate 13 for the cathode are respectively attached to the back side of the lid 11 by two pieces. In this example, the electrode plate 12 is attached to the inside and the electrode plate 13 is attached to the outside. I have.

An inner container 14 is housed in the container body 10. When the lid 11 is put on the container body 10, the positive electrode plate 12 is arranged inside the inner container 14, and the negative electrode plate 13 is arranged outside the inner container 14. Each of the electrode plates 12 and 13 is connected to the jack 3 via a plug 16 attached to the end of a lead wire 15 which passes through the center of the lid 11 and is taken out from the back side of the lid 11 to the front side. The plug 16 is detachably fitted to the jack 3, and a DC voltage is supplied to each of the electrode plates 12 and 13 from the DC power supply circuit described later via the jack 3, the plug 16, and the lead wire 15.

The positive electrode plate 12 is mainly made of a material having a low durability and a low dissolution, such as a ferrite electrode or platinum-fired titanium, and the negative electrode plate 13 is made of stainless steel. The inner container 14 is made of high quality clay or the like at a high temperature (7.
(100 to 1500 ° C.), and mainly serves as a separation membrane for separating acidic ionized water and alkali ionized water when water is electrolyzed.

FIG. 3 is a configuration diagram of a control unit including an operation panel. The unit includes a DC power supply circuit 20 that rectifies an AC 100 V power supply and supplies the DC power to the jack 3, a motor 9 that rotationally drives the rotating shaft 2, a cooling fan 8 that air-cools the high-frequency generation source 6, Source 6
And a transformer 21 for supplying power to the AC power supply, and a relay contact L1 in series with the transformer 21, a relay contact L2 in series with the cooling fan 8, and a relay in series with the motor 9. The contact L3 is connected between the DC power supply circuit 20 and the jack 3, and the relay contact L4 is connected to each.

Further, a switch SW is provided between the DC power supply circuit 20 and the motor 9, and if the switch SW is not closed, the motor 9, even if the relay contacts L1 to L3 are closed,
The cooling fan 8 and the high-frequency generation source 6 are configured so that no AC power is supplied thereto.

The relay contacts L1 to L4 are opened and closed by drive circuits T1 to T4. The drive circuits T1 to T4 are controlled by a control circuit 22 of a microcomputer.
Driven by The control circuit 22 has a built-in program memory pre-programmed to execute the control specified by the operation panel 23. The control circuit 22
Is a terminal voltage of the gas sensor 5.

The operation panel 23 includes a display section 23a for displaying a cooking time, a cooking menu, etc., a plurality of operation keys 23b for selecting various cooking menus, an operation key 23c for selecting an ion water conditioning function, and an operation start. A start key 23d for instructing is provided, and is installed on the front of the microwave oven main body adjacent to the heating chamber 1.

In this configuration, in order to use the ionized water conditioning function, the inner container 14 is housed in the container body 10, water is poured into the container body 10 and the inner container 14, and the lid 11 is inserted into the container body 10. Put on. Next, the container body 10 is housed in the heating chamber 1, and the plug 16 is fitted to the jack 3. In this state, when the operation key 23c is turned on to select the ionic water conditioning function and the start key 23d is turned on, the control circuit 22 drives the drive circuit T4 to close the relay contact L4, and the two electrode plates 12, 13 Apply a DC voltage.

In the vicinity of the positive electrode plate 12, the hydroxide ions OH ⁻ give electrons to the positive electrode plate 12 to become oxygen molecules O ₂ and escape into the air, so that the hydrogen ions H ⁺
And the water becomes acidic.

On the other hand, around the negative electrode plate 13, the hydrogen ions H ⁺ deprive the electrons from the negative electrode plate 13 and generate hydrogen molecules H _2.
Next, because escaping into the air hydroxide ions OH ^- is increased the water becomes alkaline. This is represented by the following chemical formula. Positive electrode plate 12: 4H ⁺ + 4e ⁻ → 2H ₂ Negative electrode plate 13: 4OH ⁻ → O ₂ + 2H ₂ O + 4e ⁻

Thus, the electrolysis of water is performed, and the concentration of the hydrogen gas H ₂ increases with the passage of the energization time. Accordingly, as shown in FIG. 4, the terminal voltage of the gas sensor 5 increases. The control circuit 22 reads this terminal voltage, and when it detects that the voltage has reached the preset voltage level V1, stops the drive of the drive circuit T4, opens the relay contact L4, and applies the DC voltage to both the electrode plates 12 and 13. Stop the application.

Next, the cooling fan 8 is rotated to discharge the gas filled in the heating chamber 1 from the exhaust port 4 to ensure safety. This is because the conventional ionized water conditioner is a single product, and the generated gas could be immediately released to the atmosphere. However, the present invention is to generate ionized water in the heating chamber 1 of a closed microwave oven. This is because the heating chamber 1 may be filled with gas and explode for some reason. When the electrolysis of water is completed in this way, acidic ionized water is
Alkaline ion water is generated outside the inner container 14, respectively.

When the predetermined energizing time elapses without using the gas sensor 5, the control circuit 22 forcibly shuts off energization to the electrode plates 12, 13 and rotates the cooling fan 8 to exhaust air. You may do so. But,
If the energization time is constant, the pH of the generated alkaline ionized water may be different depending on the water quality and the water temperature, and therefore it is desirable to use the gas sensor 5.

In particular, when the water quality is high or the water temperature is low, it takes a long time to generate ionic water, the amount of generated hydrogen gas is small, and the terminal voltage of the gas sensor 5 changes slowly. Therefore, the control circuit 22 detects this, and it is possible to shorten the generation time by automatically increasing the DC voltage.

Further, the following abnormality can be detected by using the gas sensor 5. In other words, even if the start key 23d is turned on to start the ionized water conditioning function, if there is no water in the container body 10 or if no DC voltage is applied to the electrode plates 12 and 13 for some reason, the normal operation is performed. Since no operation is performed, no hydrogen gas is generated, and the terminal voltage of the gas sensor 5 does not increase as shown in FIG. Therefore, if the terminal voltage of the gas sensor 5 does not change even after the power is supplied for a certain period of time, the control circuit 22 forcibly opens the relay contact L4 to stop the power supply, and displays an error on the display unit 23a.

As the gas sensor 5, a gas sensor conventionally used for detecting the finish of heating of food is used.
This gas sensor reacts to alcohol or water vapor for detecting the finish of food, but since it has no selectivity, a gas sensor that reacts to alcohol also reacts to a reducing gas such as hydrogen gas or carbon monoxide.

FIG. 6 is a structural view of a lid used as a second embodiment of the present invention. In this embodiment, the antenna 30 is attached to the lid 11 in the configuration of the above-described embodiment, and the microwaves from the high frequency generation source 6 are received by the antenna 30 at the time of preparing the ionic water, and the print is attached to the back side of the lid 11. This is an embodiment of a wireless system in which microwave energy is converted into a DC voltage by a rectifier circuit 32 formed on a substrate 31 and supplied to the electrode plates 12 and 13.
Therefore, in the present embodiment, the DC power supply circuit 2 described above is used.
0, jack 3, lead 15 and plug 16 are not required. Other configurations are the same as those of the above-described embodiment.

The antenna 30 has an antenna cover 3
3 and the printed circuit board 31 has a shield cover 3
4 are arranged so that high-frequency signals do not leak. Microwave (2450 MH)
Since the electric field density of z) increases, a voltage is sufficiently induced even with a short line or substrate (pattern) of about 3 cm as the antenna 30.

FIG. 7 is a circuit diagram of the rectifier circuit 32. A voltage signal induced by the antenna 30 is rectified by a diode D through a voltage adjusting resistor R1, and a coil L, capacitors C1 and C2, a resistor R2, The high-frequency component is removed by a low-pass filter composed of R3, and the resultant is applied to the electrode plates 12 and 13 as a DC voltage DC. If the DC voltage DC is small, a voltage doubler circuit may be added.

In this configuration, when the operation key 23c on the operation panel 23 is turned on to select the ionic water preparation function and the start key 23d is turned on, the control circuit 22 drives the drive circuit T1 to close the relay contact L1. Then, a voltage is supplied to the high frequency generation source 6 to generate a microwave. Microwaves generated from the high-frequency generation source 6 reach the heating chamber 1 through the waveguide 7, a part of which is absorbed by the water in the container body 10 to raise the temperature of the water, and the remaining part is Power is received by the antenna 30. The microwave received by the antenna 30 is converted into a DC voltage DC by the rectifier circuit 32, and
And used for electrolysis of water. At this time, since the temperature of the water in the container body 10 is increased by the microwave, the molecular motion of the water is activated, and it is considered that more water molecules hit the electrode plate to promote ionization. And ion water can be generated quickly.

According to the present embodiment, since the lead wire 15 and the plug 16 are not required, the appearance becomes smart and the handling becomes easy.
As long as there is a lid 11 provided with, a microwave oven which has been used up to now can be applied. Moreover, if it operates by manual heating, it can be applied to any microwave oven. Furthermore, it is also possible to commercialize the container body 10 and the lid 11 alone as a container body for generating ionized water.

FIG. 8 is a block diagram of a printed circuit board used as a third embodiment of the present invention, which is an improvement of the above-described wireless system. In this embodiment, a vertical antenna 30a is attached to a printed circuit board 31 attached to the back side of the lid 11.
And a plurality of horizontal antennas 30b,
Two rectifier circuits 32a and 32b corresponding to each antenna
As shown in the schematic system diagram of FIG. 9, each of the diodes D constituting the rectifier circuits 32a and 32b has a parallel configuration of two diodes.

According to this embodiment, a voltage equal to or higher than a certain constant value can be always supplied to the diode D as compared with the second embodiment. That is, the electric field intensity in the heating chamber 1 has a strong place and a weak place depending on the location due to the standing wave of the microwave. Therefore, if there is only one antenna, the voltage induced on the antenna changes greatly depending on the position of the antenna, and the DC voltage DC used for water preparation of the ionic water decreases. Therefore, if a plurality of antennas are installed as in the present embodiment, a voltage equal to or higher than a certain value can be ensured regardless of how the standing wave rises, and restrictions on how to place the container body 10 can be reduced.

Further, according to the present embodiment, the rectifier circuit 32
a, 32b can be reduced in cost. That is, power of about 20 V and about 60 mA is required to generate ionized water. However, at present, diodes capable of realizing a rectifying action in the microwave region can only be mass-produced with low power. Therefore, if two diodes are connected in parallel as in the present embodiment, the capacity of each diode can be reduced by connecting a plurality of inexpensive and small-capacity diodes. A rectifier circuit can be configured with easy diodes.

The resistance of the water forming the ionized water varies from about 100 to about 10,000 Ω depending on the temperature, quality and quantity of the water. This is a load, but it is very difficult to match a rectifier circuit to this. On the other hand, the voltage applied to the antenna changes at the point where the diode connects, and greatly changes depending on where the diode is located on the antenna. By connecting diodes at each point of the antenna, any voltage will produce a maximum voltage at that point. In this embodiment, by providing a plurality of diodes, the generated voltage can be secured to a stable level or more.

In this embodiment, since a plurality of rectifier circuits are provided and each of the rectifier circuits has an electrode, a DC voltage can be supplied stably and with a margin.
That is, when a DC voltage is supplied, normally ± voltage is applied to each electrode in one circuit, and the electrodes have the same polarity connected in parallel. However, as mentioned above, the water conditions change greatly,
In particular, when the resistance value of water decreases, the DC voltage power becomes insufficient. In order to solve this, a plurality of rectifier circuits are provided, and each of the circuits is provided with a corresponding electrode.

Further, if the positive electrode plate 12 is shared and the negative electrode plate 13 is provided for each output of each diode D, the cost can be reduced. This is because the positive electrode plate 12 uses a very expensive material such as ferrite.
On the other hand, since the negative electrode plate 13 is made of a cheap material such as stainless steel, even if a plurality of the negative electrode plates 13 are attached, the influence on the cost is small.

It should be noted that the embodiment of the wireless system can be used not only for water preparation of ionized water but also for other applications using a DC voltage. For example, various applications can be considered, such as rotating a turntable by rotating a DC motor, lighting a lamp using a DC voltage, generating a sound, transmitting a signal, and the like.

FIG. 10 is a structural view of a container body used as a fourth embodiment of the present invention. In this embodiment, when water is electrolyzed, the pH near electrode plates 12 and 13 is inevitably reduced.
Is different from the pH at a location distant therefrom, and is difficult to be uniform. Therefore, in the present embodiment, the bottom of the inner container 14 is raised, a flow hole 40 is provided on the side surface of the raised bottom, the blade 41 is attached to the rotating shaft 2, and the blade 41 is rotated by the motor 9. . In this case, as shown in FIG. 11, it is necessary to configure the inner diameter Da of the inner container 14 to be larger than the rotation diameter Db of the blade 41. Further, as shown in FIG. 12, a cut 42 may be provided instead of the flow hole 40.

With this configuration, the relay contact L2 is closed by the start of the operation of the ionized water adjusting function, the motor 8 rotates, and the rotating shaft 2 and the blade 41 rotate. The water stirred by the rotation of the blades 41 flows from the circulation hole 40 or the cut 42 to the outer periphery of the inner container 14 to make the pH of the electrolyzed alkaline ionized water (or acidic ionized water) uniform, and at the same time, ionized water. Improve the production speed.

FIG. 13 is a structural view of a container body used as a fifth embodiment of the present invention. In this embodiment, the lid 1
When the device 1 is detached from the container body 10, the electrode plate attached to the back side of the lid 11 becomes a hindrance, so that it is difficult to handle and the electrode plate made of a brittle material may be broken. Therefore, in the present embodiment, only one electrode plate is mounted on the back side of the lid 11, and the other electrode plate is mounted on the bottom surface of the container body 10.

For example, the positive electrode plate 12 is attached to the back side of the lid 11, and the negative electrode plate 50 is attached to the bottom of the container body 10. In this case, the positive voltage to the positive electrode plate 12 is supplied from the DC power supply circuit 20, and the negative voltage to the negative electrode plate 50 is supplied through the housing of the microwave oven (the bottom surface of the heating chamber 1). As shown in FIG. 14, only one voltage is supplied from the DC power supply circuit 20 to the jack 3, and the other voltage is connected (grounded) to the housing of the microwave oven.

As a result, a positive voltage is applied to the electrode plate 12 from the plug 16 via the lead wire 15, and a negative voltage (earth voltage) is applied to the electrode plate 50 from the housing via the bottom surface of the heating chamber 1 and the contact spring 51. Is applied. This is because the voltage for generating ionic water is as low as 20 to 70 V DC and the current is as low as 30 to 60 mA, so that the contact resistance of the housing is much smaller than the resistance value of water, which is not a problem.

As another structure for attaching the other electrode plate 50 to the bottom surface of the container body 10, as shown in FIG. 15, the rotating shaft 2 is formed of a conductive member, and the rotating shaft 2 may be a blade. A structure in which a functioning electrode plate 52 is attached, and a structure in which the entire bottom plate 53 of the container body 10 is formed of a conductive member as shown in FIG.

According to the present invention, it is possible to provide a new function of water conditioning of ionic water by adding a simple structure, and therefore to provide a microwave oven with further excellent multifunctionality. Becomes possible. In other words, it is possible to heat the water for preparing the ionic water by using the induction heating function of the microwave oven, which irradiates the heating chamber with microwaves to heat the object to be heated. Can be shortened.

According to the so-called wireless system of the present invention, which receives microwaves from a high frequency generation source and converts them into a DC voltage, water is poured into the container body, covered with a lid, stored in a heating chamber, and ionized. Since the water conditioning function may be selected, handling of the container body is simplified, and operability can be simplified. In addition, since the microwave heats the water, the generation time of the ionized water can be reduced.

According to the microwave oven container of the present invention, the lid has an antenna for receiving microwaves, a rectifying circuit for converting the received microwaves to a DC voltage, and an electrode plate for electrolyzing water. If the container is housed in a microwave oven and operated by manual heating, ionic water can be generated by a conventional microwave oven.
