Embodiment approach 1
[0038] figure 1 It is a front view of refrigerator 1 in Embodiment 1 of this invention. figure 2 It is a front view of refrigerator main body 1H of Embodiment 1. figure 2 Shown removed from refrigerator 1 figure 1 The state behind the doors (2, 3, 4a, 4b, 5, 6) shown.
[0039] The refrigerator 1 includes a refrigerator main body 1H having openings 1h1 to 1h5 near the front (refer to figure 2 ) and doors (2, 3, 4a, 4b, 5, 6) for opening and closing openings 1H1~1H5 (refer to figure 1 ).
[0040] exist figure 2 The illustrated refrigerator main body 1H is divided into a refrigerator compartment 2r, an ice maker compartment 4ar, a quick freezing compartment 4br, a freezer compartment 5r, and a vegetable compartment 6r from top to bottom.
[0041] Such as figure 1 As shown, a refrigerator compartment left door 2 and a refrigerator compartment right door 3 are provided on the front front of the refrigerator compartment 2r. Similarly, ice making compartment door 4a, quic...
Embodiment approach 2
[0118] Figure 13 It is a perspective schematic diagram which looked at the progress of the radio wave from the wireless module 21c in the refrigerator 21 which concerns on Embodiment 2 from obliquely upper right ahead. Figure 14 It is a side view schematic diagram which looked at the state of progress of the radio wave from the wireless module 21c in the refrigerator 21 which concerns on Embodiment 2 from the right side. also, Figure 13 , Figure 14 In the figure, the outer box 1s and the foamed heat insulating material 10 are omitted. Figure 13 , Figure 14 Only the wireless module 21c in the electrical box 9 is shown in , and other components of the electrical box 9 are omitted.
[0119] In the refrigerator 21 of Embodiment 2, for example, opening and closing figure 1 The outer panel 23a (refer to Figure 5 (c)) can also be made of steel plate instead of glass. Furthermore, it is configured so that radio waves from the antenna of the wireless module 21c can travel...
Embodiment approach 3
[0135] Figure 15 It shows the state in which the upper cover 9b of the electrical box 9 is located in the center side of the top plate 1s2 of the refrigerator according to the third embodiment in the left-right direction and embedded in a concave space inclined downward as it goes toward the rear plate 1s1 side. (The inside of the electric component storage box 9a) figure.
[0136] The configuration of Embodiment 3 can be the same as that of Embodiment 1 or 2 except for the following points.
[0137] As described above, it is preferable to shorten the wiring length of the signal line 11a3 connecting the wireless module 11c and the control signal circuit 11a2. However, if the drive circuit 11a1 that generates strong noise is close to the wireless module 11c, the influence of self-noise is likely to appear. In view of this, in the present Embodiment 3, the layout in the electric box 9 was considered.
[0138] In the electrical component storage box 9a, a steel plate 9c is ar...
