The display unit 6 is inserted into the fitting portion 35 from above through the opening 35A of the fitting portion 35 of the lower housing 3 (arrow Y11). As shown in FIG. 7 , the second engaging portion 621 of the display unit 6 is engaged with the first engaging portion 37 of the lower housing 3 . As described above, the width of the space of the first engaging portion 37 in the left-right direction decreases toward the front. Also, the width of the second engaging portion 621 in the left-right direction decreases toward the front. Therefore, forward movement of the second engaging portion 621 with respect to the first engaging portion 37 is restricted. The first engaging portion 37 and the second engaging portion 621 are in close contact while being engaged with each other.

In the groove 62G (see FIG. 6) provided in the second engaging portion 621 of each of the side surfaces 62A and 62B of the display unit 6, the groove 62G (see FIG. 6) is provided near the inside of each of the right wall 31R and left wall 31L of the lower housing 3. The protruded ridge 36 enters from below. As a result, the protrusion 36 fits into the groove 62G. As shown in FIG. 4B, the downward movement of the display unit 6 is restricted by the contact of the lower end of the display unit 6 with the projecting bottom surface 34U of the bottom surface 34 of the lower housing 3 . As a result, the display unit 6 is fitted into the fitting portion 35 of the lower housing 3 .

When the gas rice cooker 1 is used, the upper housing 2 (see FIGS. 1 and 2) is placed over the lower housing 3 in which the display unit 6 is fitted. At this time, the front projecting portion 21, the rear projecting portion 22, and the curved portion 23 of the upper housing 2 (Fig. 1, see FIG. 2) come into contact with each other. As shown in FIG. 3, the lower end of the second extended portion 212 of the fourth engaging portion 21U of the upper housing 2 contacts and engages with the third engaging portion 64A of the display unit 6 from the rear side. Movement of the third engaging portion 64A with respect to the fourth engaging portion 21U is restricted. In this way, the displacement of the display unit 6 is restricted by the engagement of the fourth engaging portion 21U with the third engaging portion 64A.

When removing the display unit 6 from the gas rice cooker 1 , first, the upper housing 2 is removed from the lower housing 3 . The fourth engaging portion 21U of the upper housing 2 is removed from the third engaging portion 64A of the display unit 6. As shown in FIG. Next, the display unit 6 is lifted upward. The protrusion 36 of the lower housing 3 is pulled out from the groove 62G of the display unit 6 . As a result, the display unit 6 is removed from the fitting portion 35 of the lower housing 3 .

<Actions and effects of the present embodiment>
In the gas rice cooker 1 , the display unit 6 is held in the lower housing 3 while being fitted in the fitting portion 35 . Here, the operator inserts the display unit 6 into the fitting portion 35 from above through the opening 35A of the lower housing 3, and by engaging the first engaging portion 37 and the second engaging portion 621, A display unit 6 can be attached to the lower housing 3 . Therefore, the worker can easily assemble the display unit 6 to the lower housing 3 in the manufacturing process of the gas rice cooker 1 . Also, the operator can remove the display unit 6 from the lower housing 3 by pulling out the protrusion 36 from the groove 62G. Therefore, the operator can easily remove the display unit 6 from the lower housing 3 during maintenance of the gas rice cooker 1 .

The width of the space of the first engaging portion 37 and the second engaging portion 621 in the left-right direction decreases toward the front. Therefore, forward movement of the second engaging portion 621 with respect to the first engaging portion 37 can be restricted, so that forward movement of the display unit 6 with respect to the lower housing 3 can be suppressed. Moreover, the display unit 6 can be attached to the lower housing 3 by fitting the protrusion 36 into the groove 62G. In this case, the horizontal movement of the display unit 6 with respect to the lower housing 3 can be suppressed by the protrusion 36 and the groove 62G.

The unit body portion 6B includes a light guide portion 61H. Each of the four display portions 611 of the light guide portion 61H has seven holes corresponding to the seven segments. The sheet 6A of the display unit 6 includes windows 613 having transparency at positions facing the plurality of holes of the light guide portion 61H. A substrate 6D of the display unit 6 has a plurality of LEDs 66 mounted at positions facing the plurality of holes of the light guide portion 61H. In this case, light emitted by the plurality of LEDs 66 passes through the holes of the light guide portion 61</b>H and the window 613 and is radiated to the front side of the display unit 6 . The control unit of the gas rice cooker 1 can display information such as numbers on the front surface of the display unit 6 by controlling the light emission patterns of the plurality of LEDs 66 . Therefore, since the gas rice cooker 1 does not require a segment type LED element for displaying information, the cost of the display unit 6 can be reduced.

The gas rice cooker 1 can improve visibility of the display unit 6 for the user by orienting the surface 61S of the front portion 61 of the unit main body portion 6B in an upwardly inclined direction.

The first upper surface portion 63 of the unit main body portion 6B prevents the boiling water from the upper end portion of the upper housing 2 from dripping downward. Therefore, the gas rice cooker 1 can reduce the possibility of sticking to the substrate 6D arranged on the back surface 61B side of the unit main body 6B. Further, side surface portions 63A and 63B connected to both ends of the first upper surface portion 63 cover the substrate 6D from both left and right sides. Therefore, the side portions 63A and 63B can further reduce the possibility that the substrate 6D will be sticky.

By engaging the fourth engaging portion 21U of the upper housing 2 with the third engaging portion 64A of the display unit 6, the gas rice cooker 1 attaches the display unit 6 to the upper housing 2 and the lower housing 3. position can be prevented from shifting.

A through hole 340 is formed in the bottom surface 34 of the lower housing 3 and in the projecting bottom surface 34U below the fitting portion 35 . Therefore, the air flowing through the through holes 340 can efficiently cool the substrate 6D.
