2. Characteristic Configuration Next, the characteristic configuration will be described.
The gas stove 1 has a housing 2, and the housing 2 has a box shape with an open upper side. The housing portion 2 is composed of an outer wall portion forming the outer wall of the gas stove 1, and a plate portion and a frame portion fixed to the outer wall portion. The housing 2 has a pair of left and right side walls (not shown), and a rear wall (not shown) connected to the rear ends of the side walls. In addition, the front part 2A of the housing part 2 is configured in a frame shape or a wall shape by a metal member or a resin member. A bottom wall portion 2B is connected to the lower portions of the front portion, the side wall portions, and the rear wall portion.

Next, each panel part 70A, 70B, 80A, 80B is demonstrated. Here, the upper panel portion 70A and the lower panel portion 80A will be explained, and the upper panel portion 70B and the lower panel portion 80B have the same configurations as the upper panel portion 70A and the lower panel portion 80A, respectively, so the explanation thereof will be omitted.

The upper panel portion 70A is a panel body that is fixed to the housing portion 2 and forms a part of the front portion of the gas stove 1 . As shown in FIGS. 4 and 5, the upper panel portion 70A is attached to the upper end side of the front portion 2A of the housing portion 2. As shown in FIGS. As shown in FIG. 1, the upper panel portion 70A has two holes through which the rotary operation portions 6A and 6D pass through in the plate thickness direction. 6D is exposed forward. A central portion of the lower end portion of the upper panel portion 70A is constituted by a transmission portion 74. As shown in FIG. As shown in FIG. 4, the upper panel portion 70A includes a panel main body 71A made of a resin material or the like and a decorative plate 71B made of a metal material or the like. As shown in FIG. 4, in the vicinity of the lower end of the upper panel portion 70A, a hole portion 75 whose inner edge portion is formed by the decorative plate 71B and the panel main body 71A is formed. 74 (lower plate portion 74B) is arranged.

As shown in FIGS. 4 and 5, the lower panel section 80A is a panel body provided on the lower side of the upper panel section 70A. and a second position (FIGS. 6 and 7) in which at least a portion is positioned more forward than the time. The lower panel portion 80A is formed in a plate shape by a panel main body and a decorative plate. The lower panel portion 80A is fixed to a frame 81, which will be described later, and can be displaced integrally with the frame 81. As shown in FIG.

The frame 81 includes a support wall portion 82 that supports the lower panel portion 80A and an extension portion 83 that extends from the support wall portion 82 and supports the operation panel portion 90 . An operation panel portion 90 is fixed near the upper end portion of the support wall portion 82 and the end portion of the extension portion 83 . The support wall portion 82 is a plate-like wall portion that is arranged in a state of standing up on the rear side of the lower panel portion when the lower panel portion is at the first position, and is positioned forward when the lower panel portion is at the second position. Make a leaning configuration. The lower panel portion 80A is fixed to the front side of the support wall portion 82 with its rear surface in close contact with the front surface of the support wall portion 82 .

The operation panel section 90 is a panel body for a user to perform various operations, and is a panel body having a predetermined operation surface 90A. The operation panel section 90 is configured integrally with the lower panel section 80A and the frame 81, and configured to be displaced (rotated) integrally with the lower panel section 80A and the frame 81. As shown in FIG. The operation panel unit 90 is a panel used for operations for executing a cooking function using a burner, a timer cooking function, and the like. is provided, and the user can set various functions by operating the operation unit 18 . The operation panel section 90 includes a panel main body 92A and a decorative cover 92B, and is attached to the frame 81. As shown in FIG. The panel main body 92A incorporates elements (such as a plurality of push buttons) that constitute the operation unit 18, and the plurality of push buttons are in contact with the back surface of the decorative cover 92B or are exposed outside the decorative cover 92B. placed in a state. In this configuration, the surface of the operation panel section 90 (operation surface 90A) is configured by the surface of the decorative cover 92B and the surface of the push buttons.

In this manner, the lower panel portion 80A, the operation panel portion 90, and the frame are integrally connected to form an operation unit. It is rotatably provided around the axis G. As the operation unit rotates around the rotation axis G, the lower panel portion 80A is placed in a first position in which it is in an upright state shown in FIGS. 2 positions and . As shown in FIGS. 6 and 7, in the second position, the upper end portion of the lower panel portion 80A is positioned further forward than in the first position. Although illustration is omitted, the lower panel portion 80A can be engaged with and disengaged from the front surface portion 2A of the housing portion 2 when it is in the first position, and is engaged with the front surface portion 2A of the housing portion 2. to fix the position at the first position. A front end portion of the operation panel portion 90 is adjacent to an upper end portion of the support wall portion 82 . A rear end portion of the operation panel portion 90 is formed with a second protrusion 90B that protrudes rearward and upward.

As shown in FIGS. 6 and 7, when the lower panel portion 80A is in the second position, at least a portion of the operation panel portion 90 (specifically, substantially the entirety of the operation panel portion 90 except for the second protrusion 90B and the vicinity thereof). ) projects forward from the upper panel portion and the operation surface 90A faces upward. As shown in FIGS. 4 and 5, when the lower panel portion 80A is at the first position, The storage position is retracted to the rear side more than in the case of . When the operation panel section 90 is in the protruding position, the operation surface 90A faces upward and is inclined so that it becomes lower toward the front. Further, the second projection 90B of the operation panel portion 90 abuts the first projection 2E of the housing portion 2 from behind, thereby restricting the forward displacement of the operation panel portion 90 from the projecting position. As a result, the lower panel portion 80A is restricted from rotating forward from the second position.

The light source 72 is, for example, an LED, and as shown in FIGS. 4 and 5, is provided behind the front surface of the upper panel portion 70A (the front surface of the decorative plate 71B). The circuit board 73 is a board on which the light source 72 is mounted, and is fixed in a predetermined posture so that the light source 72 is directed forward in a predetermined direction. Accordingly, the light source 72 is provided on the rear side of the upper panel section 70A. Further, the circuit board 73 is inclined so that the position becomes higher toward the front, and the board surface on which the light source 72 is mounted is arranged obliquely downward so that it faces forward and downward. The light source 72 is smaller in size in the horizontal direction than the hole 75 . The light source 72 is positioned behind the central portion of the hole 75 in the left-right direction. The light source 72 is arranged to irradiate illumination light forward and downward. Specifically, the light source 72 is arranged to irradiate the illumination light (see arrow L in FIG. 6) so as to pass through the hole 75 from the upper rear to the lower front.

The transmitting portion 74 is a member that transmits the light emitted from the light source 72, and is made of, for example, a light-transmitting resin and formed into a plate shape. As shown in FIGS. 4 and 5, the transmitting portion 74 is provided in a part of the lower end side of the upper panel portion 70A. Specifically, the transmitting portion 74 is configured by a flat plate-like upper plate portion 74A and a flat plate-like lower plate portion 74B, and has a substantially crank shape when viewed from the side. As shown in FIG. 4, the upper plate portion 74A is in contact with the rear surface of the upper panel portion 70A. The lower plate portion 74B is positioned inside the hole portion 75 . The transmission portion 74 has a front surface (the front surface of the lower plate portion 74B) arranged flush with the front surface of the upper panel portion 70A. As a result, the transmissive portion 74 can be integrated with the upper panel portion 70A, and can be prevented from impairing the appearance due to being provided on the lower end side of the upper panel portion 70A.

The detection switch SW corresponds to an example of a detection section and has a function of detecting the position of the operation panel section 90 . The detection switch SW is composed of a switch and a sensor. For example, when the operation panel section 90 is in the retracted position, a first signal (non-detection signal) is input to a predetermined signal line connected to the control section 91 . It has become so. The detection switch SW is arranged, for example, in the housing section 2 as shown in FIGS. 4 and 5 . The control unit 91 is configured as, for example, a known microcomputer. The control section 91 may be configured by the control circuit 10 or may be configured as a control circuit separate from the control circuit 10 . Specifically, a voltage equal to or lower than the threshold voltage (for example, 0 V) is applied to the signal line. On the other hand, when the operation panel section 90 is at the projecting position, the second signal (detection signal) is input to the signal line connected to the control section 91 . Specifically, a voltage (for example, 5 V) exceeding the threshold voltage is applied to the signal line.

Note that the detection switch SW and the peripheral circuit are not particularly limited as long as they are configured to perform such switching, and various parts and circuit configurations can be adopted. For example, if the detection switch SW is a button type switch, the detection switch SW is pushed by the operation panel section 90 when the operation panel section 90 is in the retracted position. and a predetermined ground line, a first signal (for example, a non-detection signal of 0 V) is applied to the signal line. Although illustration is omitted, the detection switch SW is pushed by the operation panel section 90 or a member interlocking with the operation panel section 90 . On the other hand, when the operation panel portion 90 is at the projecting position, the operation panel portion 90 does not push the detection switch SW, and at this time, the detection switch SW is turned off so as to electrically insulate the signal line from the ground line. , a second signal (eg, a sense signal greater than 0V) is applied to the signal line. In this case, for example, a second signal (for example, a 5V detection signal) may be applied to the signal line from a predetermined constant-voltage power supply line through a resistor. The control unit 91 turns off the light source 72 (non-irradiation state) when the first signal is input by the operation of the detection switch SW, that is, when the operation panel unit 90 is in the retracted position, and the operation panel unit 90 is at the projected position, the light source 72 is turned on (illuminated state).

Next, operation of the operation panel section 90 will be described.
As shown in FIGS. 4 and 5, when the lower panel portion 80A is at the first position, the operation panel portion 90 is at the retracted position, the detection switch SW is pressed by the operation panel portion 90 to turn on, and the light source is turned on. 72 is in an off state (non-irradiation state). When operating the operation panel portion 90 with the lower panel portion 80A at the first position, for example, by pulling out the upper end portion of the lower panel portion 80A forward, the lower panel portion 80A is moved from the first position to the second position. Rotate to position. Then, the lower panel portion 80A rotates around the rotation axis G from the upright state, and enters the tilted state shown in FIGS. At this time, the operation panel section 90 rotates integrally with the lower panel section 80A, and is displaced from the retracted position shown in FIGS. 4 and 5 to the projecting position shown in FIGS. As a result, the operation surface 90A is arranged to face forward and upward. The second protrusion 90B of the operation panel portion 90 abuts the first protrusion 2E of the housing portion 2 from behind, thereby restricting the operation panel portion 90 from moving forward from the projecting position.

Then, when the operation panel portion 90 is displaced to the projecting position, the operation panel portion 90 moves away from the detection switch SW, thereby turning off the detection switch SW and turning on the light source 72 (illumination state). As a result, the light source 72 irradiates the operation surface 90A with illumination light from the rear upper side as indicated by an arrow L shown in FIGS. 6 and 7 . Specifically, the light source 72 emits illumination light from above at an irradiation angle (the angle at which the operation surface 90A and the arrow L intersect) that is larger in the vertical direction than the inclination of the operation surface 90A. Therefore, a wide area on the operation surface 90A is illuminated with the illumination light.

Further, when the lower panel portion 80A is rotated from the first position to the second position, the detection switch SW is no longer pressed, and the light source 72 is automatically switched from the off state (non-illumination state) to the on state (illumination state). switch to Therefore, it is possible to make the operation panel section 90 brighter more easily, and it is possible to reduce the promptness caused by pressing the wrong operation button due to a situation in which the operation is forced to be performed in the dark, or taking time to confirm the operation button. It is possible to suppress the decrease in the operation load and the increase in the operation load.

After the operation of the operation panel portion 90 is completed, the lower panel portion 80A is rotated from the second position to the first position about the rotation axis G, and locked to the front surface portion 2A of the housing portion 2. The operation panel section 90 is displaced from the projecting position to the retracted position. As a result, the operation panel unit 90 presses the detection switch SW, the detection switch SW is turned on, and the light source 72 is turned off (non-irradiation state).

Here, the effect of this structure is illustrated.
The gas stove 1 is configured such that when illumination light is emitted from the light source 72 while the operation panel portion 90 is in the projecting position, at least part of the illumination light from the light source 72 is emitted to the operation surface 90A. . With such a configuration, the operation surface 90A can be brightly illuminated using the light from the light source 72 incorporated in the rear side of the upper panel portion 70A without providing a special dedicated illumination outside the gas stove. . Therefore, in the gas stove 1 provided with the operation panel portion 90 that can be changed between the protruded state and the retracted state, a special configuration outside the gas stove that can brightly illuminate the operation surface 90A when the operation surface 90A is in the exposed state is provided. It can be realized more easily without using a dedicated device. In particular, when the operation surface 90A is exposed, it becomes easier to see the operation surface 90A in a clear state.
In addition, a transmission section 74 is provided as a part of the lower end side of the upper panel section 70A, and a path for guiding light from the light source 72 to the operation surface 90A using a part of the lower end side of the upper panel section 70A. can be assured. Instead of providing the transmissive portion 74 as a part of the upper panel portion 70A, the transmitting portion 74 may be formed separately from the upper panel portion 70A and arranged between the upper panel portion 70A and the lower panel portion 80A. Similar effects can be obtained in this way as well.
In addition, since the front surface of the transmission section 74 and the front surface of the upper panel section 70A are arranged flush with each other, the integration between the transmission section 74 and the upper panel section 70A can be enhanced, and the transmission section 74 can be provided. It is possible to prevent the aesthetic appearance from being spoiled.
Further, the user can switch the light source 72 to the illumination state by simply performing a simple operation of "displacing the operation panel section 90 to the projecting position." Separately, it is possible to irradiate the operation surface 90A with illumination light without performing a complicated dedicated operation.
