Description

Heater and Ventilating Device

The present invention relates to a heating device and a ventilation device.

BACKGROUND ART A technique for starting or stopping a ventilation device is known in conjunction with a heating start or a heating stop of a heating device. In this technique, an infrared signal transmitting unit is provided in a heating device, and an infrared signal receiving unit is provided in a ventilation device. In this case, it is also proposed to install the transmitter section in front of the heating apparatus and the receiver section in front of the ventilation apparatus. In this method, the infrared signal transmitted from the transmitter hits the operator or the like and is reflected, and the reflected infrared signal is received at the receiver, thereby interlocking the heating start or heating stop of the heating device with the operation start or stop of the ventilation device.

According to the above method, since the transmitting unit does not need to be installed on the upper surface of the upper plate of the heating apparatus, there is an advantage that dirt, such as cooking soup, becomes difficult to attach to the transmitting unit.

In the prior art, the light emitting surface of the transmitting section of the heating apparatus is provided in parallel to the front surface of the heating apparatus, and the transmitted infrared signal is transmitted perpendicularly to the front surface of the heating apparatus. According to this system, however, depending on the position of the operator and the like, the infrared signal may not hit the operator. As a result, the infrared receiver may not be able to receive the infrared signal.

Moreover, in the prior art, the light receiving surface of the receiver of the ventilator is formed in the vertical plane so that the infrared signal incident in the horizontal direction can be best received. According to this system, however, there is a case where the receiving unit cannot receive the infrared signal depending on the position of the operator.

It is an object of the present invention to provide a technique for maintaining a high probability that an infrared signal is transmitted and received reliably between a heating device and a ventilation device, regardless of the operator's position or the like.

In the ventilator according to claim 4, in addition to the receiver, it is preferable to further install another receiver inside the ventilator (claim 8).

According to the ventilation apparatus of Claim 8, since an infrared signal of a wider range can be received than before, an infrared signal can be received with a higher probability than before.

In this way, in addition to the first receiver 33, the second receiver 35 is further provided inside the hood body 31 to receive a wide range of infrared signals.

Subsequently, the electrical connection between the gas stove 22 and the range hood 30 according to the present embodiment will be described with reference to FIG. 2. 2 is a view showing the electrical connection between the gas stove and the range hood according to the present embodiment.

As shown in FIG. 2, each ignition switch 26a-26d shown in FIG. 1 is connected to the switch detection part 40 inside the gas furnace 22. As shown in FIG. The switch detection section 40 detects the ON / OFF state of each ignition switch 26a to 26d. This switch detection section 40 is connected to an origination control section 42, which is connected to an origination LED 44 (an example of an infrared light emitting element). In the present embodiment, the transmitting unit 28 shown in Fig. 1 is constituted by the transmitting LED 44 and the light emitting cover (not shown).

Subsequently, a basic operation including the features of the gas stove 22 and the range hood 30 according to the present embodiment will be described with reference to FIG. 3. 3 is a side view of the gas stove and range hood according to the present embodiment.

As shown in FIG. 3, when the operator 60 presses the ignition switch 26 to ignite the working part 24, the infrared signal is transmitted from the transmitter 28 by the electrical connection shown in FIG. The transmitter 28 is provided on the front of the main body 23, and when the operator 60 operates the ignition switch 26, it is usually located near the front of the main body 23, and thus the The infrared signal hits the body of the operator 60. The infrared signal reflected by hitting the body of the operator 60 is irradiated in the direction of the range hood 30 on the upper side of the gas furnace 22. When the infrared signal is received by the first receiver 33 installed in the front center of the range hood 30 or the second receiver 35 installed therein, the operation of the ventilation fan 36 is stopped by the electrical connection. Is initiated. Exceptionally, even if the infrared signal transmitted from the transmitter 28 does not hit the body of the operator 60 or the like, when the infrared signal reflected from the ceiling 62c is received by the first receiver 33, The operation of the ventilation fan 36 is initiated by one electrical connection.

On the other hand, even when the operator 60 presses the ignition switch 26 again to stop the operation of the working section 24, the operation of the ventilation fan 36 is stopped by the above operation.

Hereinafter, the characteristic constitution and effect of the gas furnace 22 and the range hood 30 which concern on this embodiment are demonstrated in detail.

As shown in Fig. 4, which is a plan view of the gas furnace 22, the light emitting surfaces of the transmitters 28a and 28b are inclined at 45 degrees toward the center, respectively. Since the transmission range of the infrared signal transmitted from one transmitter is about 30 degrees, the infrared signal is irradiated over the area where the area A1 and the area A2 are combined in the two transmitters 28a and 28b without considering reflection or the like. . As a result, for example, in the case of operating the ignition switch 26d, the ignition switch may of course be operated by the operator 60 in front of the ignition switch 26d (in the case of the operator operating in the position of 60a). Even when the hand is extended and operated from the position out of the front of (26d) (the operator operates at the position of 60b or 60c), the infrared signal hits the body of the operator 60. Other ignition switches 26a to 26c The same applies to the case of operating the light emitting device, except that even when the infrared signal does not strike the body of the operator 60, since the light emitting surface is inclined 45 degrees toward the center, as shown in FIG. When the side wall 62a is within a distance of 3m, an infrared signal strikes the side wall 62a. Thus, the infrared signal transmitted from the transmitter 28 is transmitted to the body of the operator 60 or the side wall 62a. Bumped into Since it is easy to reflect, the reflected infrared signal is easy to irradiate toward the 1st receiving part 33 of the range hood 30 etc. (refer FIG. 3).

Although the exception is the case where the rear wall 62b is located within a distance of about 3 m within which the infrared signal can be reached, the infrared signal reflected by the rear wall 62b may be received by the first receiver 33 or the like. .

In addition, as shown in FIG. 5, which is a side view of the gas furnace 22, the light emitting surfaces of the transmitters 28a and 28b are inclined 10 degrees toward the upper side. Since the transmission range of the infrared signal transmitted from one transmitter is about 30 degrees, the infrared signal is irradiated over the area A3 in the two transmitters 28a and 28b unless reflection or the like is taken into consideration. As a result, it is possible to reach the first receiver 33 or the like (see FIG. 3) of the range hood 30 provided above the gas stove 22 with a higher probability than the conventional one.

As shown in FIG. 6, which is a perspective view of the first receiving unit 33 and the operating unit 32 of the range hood 30, the first receiving unit 33 includes a first light receiving surface 34a and a second light receiving surface 34b. The outer frame is formed by the formed light receiving cover 34. As shown in FIG. 7, which is a sectional view of the vicinity of the first receiver 33, the light receiving cover 34 has a circuit board 64, a control element 66 attached to the circuit board 64, And a receiving LED 48 attached to the control element 66.

As shown in Fig. 7, the light receiving surface of the receiving LED 48 is inclined downward, and its inclination angle is 40 degrees. The inclination angle of 40 degrees is based on the results of the present study described below.

8 shows the reception frequency and reception probability of the infrared signal by the first receiver 33 in the case where the position and the inclination angle of the doll (equivalent to the operator) are changed. In addition, the doll (1500 mm tall) is 250 mm away from the transmitter 28, and is placed in the center of the gas stove 22, 200 mm from the center, and 200 mm from the center. The case was examined. Moreover, the case where the inclination angle was changed every 10 degrees from 20 degrees to 60 degrees was examined. The number of times of transmission of the infrared signal was set to 20 times.

As shown in Fig. 8, in the case where the inclination angle was 40 degrees, the reception frequency was 20 times, that is, the reception probability was 100% at any position. When the inclination angle was set at 30 degrees or 50 degrees, the reception probability was slightly lower than that at 40 degrees. In addition, when the doll is placed on the left or right side, the reception probability is slightly lower than when the doll is placed in the center, but as described in the example of FIG. In the case where the inclination angle was set at 20 degrees or 60 degrees, the reception probability dropped significantly compared to the case in which the inclination angle was set at 30 degrees to 50 degrees. As described above, when the inclination angle of the light receiving surface of the reception LED 48 is 40 degrees, an infrared signal reflected by a person or the like and irradiated from the lower side can be received with a higher probability than before, and an red line reflected from the ceiling or the like and irradiated from the upper side Signals can also be received.

As shown in Fig. 7, the first light receiving surface 34a of the light receiving cover 34 is inclined downward, and its inclination angle is 50 degrees. In addition, the second light receiving surface 34b is inclined 50 degrees with respect to the first light receiving surface 34a. According to this structure, the infrared signal reflected by a person etc. and irradiated from the lower side can be received with a higher probability than before, and the infrared signal reflected from the ceiling etc. and irradiated from the upper side can also be received with a high probability.

When the inclination angle toward the lower side of the first light receiving surface 34a is 50 degrees, the inclination angle toward the upper side with respect to the first light receiving name 34a of the second light receiving surface 34b is any one of 40 degrees to 60 degrees. It is preferable that it is an inclination angle.

As shown in FIG. 9, which is a side view of the first receiver 33 and the operation unit 32, the inclination angle toward the lower side of the operation surface of the operation unit 32 is 30 degrees. As described above, the inclination angle toward the lower side of the first light receiving surface 34a of the light receiving cover 34 constituting the first receiving unit 33 is 50 degrees. That is, the inclination angle of the operation surface of the operation part 32 is made smaller than the inclination angle of the 1st light receiving surface 34a of the light receiving cover 34 which comprises the 1st receiving part 33. FIG. According to this structure, an infrared signal can be received with a higher probability than before, and it can be made not to impair the operability of the operation part 32. FIG.

As mentioned above, although the gas stove 22 and the range hood 30 which concern on embodiment of this invention were demonstrated, this invention is not limited to the above-mentioned embodiment at all, Based on the knowledge of a person skilled in the art, various changes and improvement are made. It can be done in one form.

For example, in the present embodiment, as shown in Fig. 1, the gas cooker 22 having the transmitter 28 provided in the front and the range hood 30 provided with the first receiver 33 in the front are combined. Although described, the scope of application of the present invention is not limited to this. For example, as shown in FIG. 1, the present invention can be applied to a case where a gas stove 22 having a transmitting part 28 provided on the front side and another range hood not shown on the lower side or the side thereof are combined. Can be. In addition, the present invention can be applied to a case where a gas hood (not shown) provided with a transmitter on an upper surface and the range hood 30 provided with a first receiver 33 on the front side as shown in FIG. 1 are combined.
