Abstract

PROBLEM TO BE SOLVED: To simultaneously dry and sterilize a kitchen knife by induction heating the kitchen knife housed in a waterdrop sticking state by controlling an inverter on the basis of detecting temperature information of a temperature detecting means for detecting an atmospheric temperature in a case by a control means. SOLUTION: A switching element performs switching operation by an ON signal from a control circuit 9, and an inverter 8 converts a frequency into a prescribed frequency to be supplied to a heating coil 7. The heating coil 7 generates a high frequency magnetic field according to a high frequency current. Since a kitchen knife 5 is composed of stainless steel or iron, the kitchen knife is inductively heated by interlinking the high frequency magnetic field. The kitchen knife 5 is dried by heating by this induction heating, and a waterdrop sticking to a surface quickly evaporates. Since a temperature detecting means 10 is arranged in a case 6, a rise in an atmospheric temperature by radiation heat from the kitchen knife 5 is detected so that this information is transmitted to the control circuit 9.

(Embodiment 1) A first embodiment of the present invention will be described below. FIG. 1 is an internal transparent perspective view showing the configuration of the present embodiment. The case 6 has a storage section 5 a for storing the kitchen knife 5.
It has. A heating coil 7 for generating a high-frequency magnetic field is fixedly arranged on the side surface of the case 6. The end of the heating coil 7 is connected to an inverter 8,
A high frequency current is supplied from the inverter 8. The ON / OFF of the inverter 8 is controlled by the control circuit 9. Further, inside the case 6, a temperature detecting means 10 constituted by a thermistor or the like is provided.

FIG. 2 is a circuit diagram showing the electrical connection of this embodiment. In the present embodiment, the inverter 8 converts the commercial AC 100 V into a high frequency of, for example, 20 kHz and supplies the high frequency to the heating coil 7. This inverter 8
Are controlled on and off by the control circuit 9. That is, the output signal of the control circuit 9 is connected to the gate terminal of the switching element 8a of the inverter 8. Further, the detected temperature information of the temperature detecting means 10 is transmitted to the control circuit 9.

The operation of this embodiment will be described below.
When a switch (not shown) is turned on, the control circuit 9 operates and the inverter 8 starts operating. That is, the switching element 8 is turned on by the ON signal from the control circuit 9.
a performs a switching operation, the inverter 8 converts the commercial AC 100 V into a high frequency of 20 kHz,
Is to be supplied to The heating coil 7 generates a high-frequency magnetic field corresponding to the high-frequency current. Since the kitchen knife 5 is made of stainless steel or iron, it is induction-heated by interlinking the high-frequency magnetic field.
The kitchen knife 5 is dried by the heat generated by the induction heating, and water droplets adhering to the surface evaporate quickly. At this time, in this embodiment, the temperature detecting means 10 is provided in the case 6. The temperature detecting means 10 detects an increase in ambient temperature due to radiant heat from the kitchen knife 5, and outputs this information to the control circuit 9.
To communicate. The control circuit 9 acts to stop the operation of the inverter 8 when the temperature detected by the temperature detecting means 10 exceeds a predetermined value. For this reason, the temperature in the case 6 is maintained in a predetermined temperature range.

In this embodiment, the control circuit 9 automatically determines whether the kitchen knife 5 is in the storage section 6. In other words, the control circuit 9 detects the presence and absence of the kitchen knife 5 by detecting the current and voltage in the inverter 8 and judging the phase relationship and magnitude relationship between the current and voltage. When the control circuit 9 determines that there is no kitchen knife 5, the operation of the inverter 8 is stopped.

As described above, according to this embodiment, since the kitchen knife 5 is induction-heated by the high-frequency magnetic field generated by the heating coil 7, the kitchen knife 5 itself generates heat. That is,
The surface temperature of the kitchen knife 5 is so high that bacteria cannot grow. Kitchen knives are especially used for handling raw fish and meat, and washing and drying alone are not enough for sterilization. According to the inventors' research, for example, if O157 is kept at 75 ° C for 10 minutes, E. coli will be 3 ° C at 60 ° C.
If you keep it for 0 minutes, it will almost die. Therefore, in the present embodiment, the control program of the control circuit 9 is set in advance so that the temperature and time required for all of these main bacteria to die are set. In other words, the relationship between the output power of the inverter 8 and the drive time is set in the control program.

Therefore, according to the present embodiment, it is possible to realize a kitchen knife drying and storing apparatus capable of simultaneously performing drying and sterilization.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 3 is an internal transparent perspective view illustrating the configuration of the present embodiment. In the present embodiment, the temperature detecting means described in the first embodiment is arranged in each of the kitchen knife housing sections 6a, 6b, 6c. That is, the temperature detecting means 1 arranged in each of the kitchen knife accommodating sections 6a, 6b, 6c
1a, 11b and 11c are provided so as to directly contact the blade of the kitchen knife 5 when the kitchen knife 5 is stored.

With the above configuration, the control of the control circuit 9 becomes very accurate. In other words, the temperature of each kitchen knife 5 can be accurately known, and the ON / OFF control timing of the inverter 8 can be accurately adjusted. In addition, by using a plurality of temperature detecting means, it is possible to determine whether the kitchen knife is inserted or removed, and to perform control so that wasteful power consumption due to reheating of the kitchen knife is eliminated.

(Embodiment 3) Next, a third embodiment of the present invention will be described. FIG. 4 is an internal transparent perspective view showing the configuration of the present embodiment. In the present embodiment, a radiation type temperature sensor 12 such as an infrared sensor is used as the temperature detecting means described in the first embodiment or the second embodiment. By using the radiation temperature sensor 12, the temperature of the kitchen knife 5 can be detected in a non-contact manner. Therefore,
When the temperature sensor comes into contact with the kitchen knife 5, foreign matter does not come into contact with the kitchen knife 5, and clean storage can be performed.
