  The pedal is externally attached to the housing 2 and is connected to the housing 2 via a cable. The pedal includes a pressure detection sensor that detects the pressure of the operator. For example, a pressure sensor that detects a pressure applied to the diaphragm (diaphragm) as a deformation of the membrane can be used as the pressure detection sensor.

  The open / close detection sensor detects opening / closing of the open / close door 5 and is composed of, for example, a magnet provided on the housing 2 side and a sensor provided on the open / close door 5 side, and the open / close door 5 is opened / closed. The opening / closing of the door 5 is detected by a change in the magnetic field.

It is a computer circuit. Then, by operating according to a control program stored in a predetermined area of the internal memory, the CPU and peripheral devices operate cooperatively to perform their functions.

  When the open / close detection sensor detects that the open / close door 5 is open, or when the press detection sensor detects that the pedal is not pressed, the laser oscillator 3a does not output laser light. A stop signal is transmitted to 3a.

  Further, when the open / close detection sensor detects that the open / close door 5 is closed, and when the press detection sensor detects that the pedal is pressed, the laser beam is output from the laser oscillator 3a. An output signal is transmitted to the laser oscillator 3a.

  In addition, the first control unit transmits a warning signal to the alarm device 4a when the open / close detection sensor detects that the open / close door 5 is open and the pedal is pressed.

  The alarm device 4a alerts the operator, and is provided on the horizontal surface 21 of the housing 2, and receives a warning signal from the first control unit and emits a buzzer sound or blinks light. It is.

  The operation of the laser cooker 1 in this embodiment will be described below.

<During normal operation>
When the operator cooks food, the operator holds the handle 5 a, opens the door 5 as shown in FIG. 2, and places the food on a mounting table (not shown) provided in the housing 2. When the food is placed, the door 5 is closed as shown in FIG. At this time, the opening / closing detection sensor detects opening / closing of the opening / closing door 5 and transmits an opening / closing signal to the first control unit.

  Next, as shown in FIG. 6, the operator inserts both hands into the food operation holes 6 a and 6 b of the housing 2 and holds the food with both hands. At this time, the operator can observe the state in the housing 2 from the transparent window 8. Then, after confirming that the changeover switch is in a position where the laser beam is blocked, the pedal is pressed with a foot. Then, a press detection sensor detects the press of a pedal, and transmits a press signal to the 1st control part.

  The first control unit receives the closing signal of the opening / closing door 5 transmitted from the opening / closing detection sensor, and receives the pressing signal transmitted from the pressing detection sensor, the output signal so as to oscillate visible light from the visible light oscillator. And an output signal is transmitted from the laser oscillator 3a so as to oscillate the laser beam.

  As shown in FIG. 7, the visible light oscillator receives an output signal from the first control unit and outputs visible light. Visible light passes through the visible light emitting tube 16a and enters the blocking plate 17a. Visible light incident on the blocking plate 17a is totally reflected, collimated by the collimator lens 3c, converged by the convex lens 3d, emitted from the laser emission port 7, and irradiated on the food.

  At this time, the laser oscillator 3a also receives the output signal from the first controller and outputs laser light. As shown in FIG. 8, the laser light output from the laser oscillator 3a is incident on the laser emission tube 11 via the optical fiber 3b, but is blocked by a blocking plate 17a disposed so as to close the laser emission tube 11. Yes.

  When the operator moves the food so that visible light is emitted to a desired position of the food, the operator switches the changeover switch in that state to move the blocking plate 17a to a position where the visible light is blocked.

  Then, since the blocking plate 17a moves to a position that closes the visible light emitting tube 16a, the visible light is blocked by the blocking plate 17a and the laser light transmitted through the laser emitting tube 11 is made parallel by the collimator lens 3c. The light is converged by the convex lens 3d and emitted from the laser emission port 7. Since the food irradiated with the laser light is heated and has a baked line, the operator assumes that the baked line is the position where the laser beam is applied, and the laser beam is emitted to a desired position. Move food.

  In addition, since the focal point of the laser beam is configured to be located above the food placing surface in the housing 2, when the food item is moved in the vertical direction, the density of the laser beam is changed, The baking can be changed. For example, when the food is moved so as to be close to the focal point of the laser beam, the food is irradiated with a laser beam having a relatively high density, so that the food can be strengthened. Conversely, when the food is moved away from the focal point of the laser beam, the food is irradiated with a laser beam having a relatively low density, so that the cooking of the food can be weakened.

<At warning>
If the operator accidentally steps on the pedal with the open / close door 5 open, the first control unit receives an open signal indicating that the open / close door 5 is open from the open / close detection sensor, and from the press detection sensor. A pressing signal indicating that the pedal is pressed is received, and an alarm signal is transmitted to the alarm device 4a. In response to the alarm signal, the alarm device 4a sounds a buzzer or flashes light to alert the operator. When the alarm device 4a is activated, the operator takes measures such as closing the opening / closing door 5 or stopping the pressing of the pedal.

  The laser cooker 1 of 1st Embodiment comprised as mentioned above has the following special effects.

  That is, since the operator can move the food freely by putting his hands through the food operation holes 6a and 6b during cooking, the laser beam can be irradiated to a desired position without requiring complicated control. Therefore, even foods like shank that are hard and hard to eat, for example, can be easily processed softly by irradiating the muscle with laser light, making it possible to eat deliciously Become. Further, since the inside of the housing 2 can be visually recognized from the outside of the housing 2 through the transparent window 8 for attenuating the laser light, the laser cooker that prevents the laser light from directly entering the eyes of the operator and is considered in terms of safety. 1 can be provided.

  Since the transparent window 8 provided on the upper surface 2c of the housing 2 is arranged in front of the operator and the food operation holes 6 are arranged at both ends thereof, the operator can operate both arms while looking through the transparent window 8. The food can be moved freely in the hole 6 and the operability of cooking can be improved.

  Since the transparent window 8 is provided on the inclined surface 20, the operator can look into the transparent window 8 in a natural posture, and in addition, the inclined surface 20 is sandwiched and the interval is reduced toward the front surface 2a. Since the food operation hole 6 is provided on each of the both side surfaces, the distance between the operator and the food operation hole 6 can be shortened so that the operator can easily put the hand into the food operation hole 6. Therefore, the operability of cooking can be further improved.

  Since the focal point of the laser beam is configured to be positioned above the food placing surface in the housing 2, when the food item is brought close to the focal point of the laser beam, the laser beam is irradiated with a high density. Conversely, when the focus of the laser beam is kept away from the food, the food can be irradiated with a low-density laser beam. Therefore, by moving the food in the vertical direction by the operator and changing the light density of the laser light applied to the food, the food can be processed in accordance with the desired baking.

  Since the transparent member 12 that is detachably attached so as to cover the laser emission port 7 is further provided, the juice released from the food when the food is irradiated with the laser light is prevented from adhering to the laser emission port 7. Can do. In addition, since the transparent member 12 is detachably attached to the laser emission port 7, cleaning can be easily performed even if the transparent member 12 becomes dirty.

  Since the food operation holes 6a and 6b are provided with a notch for the operator to put a hand in the housing 2 and covered with the light blocking film 10 that prevents the laser light from leaking outside the housing 2, Laser light can be prevented from being emitted from the food operation holes 6a and 6b and entering the eyes of the operator, and the laser cooker 1 can be provided in consideration of safety.

  When the open / close door 5 is open, it further includes a fail-safe mechanism 4 that stops the irradiation of the laser beam to the food. Therefore, when the open / close door 5 is open, the laser beam is not irradiated to the food. It is possible to prevent the laser beam from leaking and accidentally enter the eyes of the operator, thereby improving safety.

  Visible light for aiming the laser light is emitted from the laser emission port 7, so that it can be aimed with visible light instead of the laser light in the infrared wavelength region of the invisible wavelength region, The food can be cooked by aiming the laser beam at a desired position of the operator.

  In addition, as a specific aspect of the laser cooker 1 of the present invention, since at least a part of the inner surface of the housing 2 is composed of a light absorbing member that absorbs laser light, the outside of the housing 2 It is possible to prevent the laser light from leaking to the operator and to prevent the operator's eyes from being directly irradiated with the laser light.
