Description

The following disclosure pertains to washing machines. For example, Patent Document 1 discloses a shielding structure for electronic equipment that uses a shielding case to protect it from external electromagnetic waves and prevent internally generated electromagnetic waves from affecting other electronic equipment. Japanese Patent Application Publication No. 10-154895 This is a schematic perspective view showing the internal structure of the washing machine 1 according to the embodiment.This is a schematic cross-sectional view showing the internal structure of the washing machine 1 according to the embodiment.This is a schematic diagram illustrating the layout of the circuit board inside washing machine 1.This is a schematic diagram illustrating the layout of the circuit board inside washing machine 1.This is a schematic diagram illustrating the layout of the circuit board inside washing machine 1.This is a schematic diagram illustrating the layout of the circuit board inside washing machine 1.This is a schematic diagram illustrating the layout of the circuit board inside washing machine 1. The embodiments of the washing machine and other devices described herein will be explained below with reference to the drawings. This disclosure is not limited to the embodiments described below, and design modifications can be made as appropriate within the scope of satisfying the configuration of this disclosure. In the drawings, identical or equivalent elements are denoted by the same reference numerals, and redundant explanations are omitted. The following explanation will focus on the main parts and parts related to this disclosure. In this disclosure, "washing machine" refers to all equipment that performs various processes on laundry, such as washing. Examples of laundry processes include washing, drying, deodorizing, and disinfecting. The laundry is not particularly limited. Examples of laundry include textile products. Specific examples of laundry include clothing such as clothes, hats, and gloves; personal belongings such as shoes, bags, handkerchiefs, and towels; curtains; bedding such as blankets, towels, and duvet covers; carpets; stuffed animals; and so on. A "top-loading washing machine" refers to a washing machine in which, when installed, the rotation axis of the drum extends substantially vertically. (Embodiment) Figure 1 is a schematic perspective view showing the internal structure of the washing machine 1 of the embodiment. Figure 2 is a schematic cross-sectional view (side cross-sectional view) showing the internal structure of the washing machine 1 of the embodiment. Figures 3 to 5 are schematic diagrams illustrating the arrangement of the circuit board inside the washing machine 1, of which Figure 3 is a view from above, Figure 4 is a view from the rear, and Figure 5 is a view from the left. The washing machine 1 will be described with reference to Figures 1 to 5. The washing machine 1 has a roughly rectangular prism shape. When the washing machine 1 is placed on a horizontal surface, the direction from the washing machine 1 toward the user is defined as the front direction, the direction opposite to the front direction (the rear side of the washing machine 1) is defined as the rear direction, the left side when looking from the washing machine 1 toward the front is defined as the left direction, the right side as the right direction, the upper side in the vertical direction is defined as the up direction, and the lower side as the down direction. In the description of each component of the washing machine 1, the direction shall be expressed in the direction in which the component is attached to the washing machine 1. For example, the front of a component is the part located in front of the centroid of the horizontal cross-section of the component, and the rear of a component is the part located behind the centroid of the horizontal cross-section of the component. The left of a component is the part located to the left of the centroid of the horizontal cross-section of the component, and the right of a component is the part located to the right of the centroid of the horizontal cross-section of the component. The upper part of a component is the part located above the centroid of the vertical cross-section of the component, and the lower part of a component is the part located below the centroid of the vertical cross-section of the component. The washing machine 1 has a housing 10 having a first metal side wall 10A1, a second metal side wall 10A2 connected to the first side wall 10A1, and a first corner portion 10B1 formed by the first side wall 10A1 and the second side wall 10A2, and a first circuit board 11A having a mounting surface 11A1 on which electronic components are mounted and a back surface 11A2 located on the opposite side of the mounting surface 11A1, and the mounting surface 11A1 is positioned on the inner corner side of the first corner portion 10B1 so as to face the first corner
