Description

【Technical Field】 【0001】 The present invention relates to, for example, a washing machine pan on which a washing machine is placed and a method for manufacturing the washing machine pan. 【Background Art】 【0002】 Conventionally, at the installation location of a washing machine, it has been common practice to construct a washing machine pan and install the washing machine on the washing machine pan. As a conventional washing machine pan 10 (waterproof pan), as shown in FIG. 21, there is one having a bottom surface 3 integrally provided with an annular outer peripheral wall 2 (flange portion) and mounting portions 5 (raised portions) formed at the four corners of the bottom surface 3 (see Patent Document 1). The mounting portion 5 has a flat upper surface that is higher than the bottom surface 3 and lower than the upper surface of the outer peripheral wall 2. A drain hole 6 is formed in the bottom surface 3. When the washing machine 50 is installed on the washing machine pan 10, the four legs of the washing machine 50 are respectively placed on the upper surfaces of the four mounting portions 5. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Unexamined Patent Application Publication No. 2002 - 121795 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 Slip prevention rubber or resin leg covers may be attached to the tips of the legs of the washing machine 50, and the washing machine 50 may be installed such that the leg covers contact the upper surface of the mounting portion 5. However, for example, due to vibrations during dehydration, the position of the washing machine 50 may shift, and any one of the four legs may come off the mounting portion 5, causing the washing machine 50 to tilt. FIG. 22 shows a state where, for example, the washing machine 50 has shifted to the front side and the two legs on the back side have dropped from the mounting portion 5 on the back side of the washing machine pan 10. 【0005】 Therefore, the present invention aims to provide a washing machine pan and a method for manufacturing a washing machine pan that can prevent a washing machine installed on the washing machine pan from falling off the mounting surface due to a shift in the position of the washing machine's legs. [Means for solving the problem] 【0006】 A washing machine pan according to one aspect of the present invention comprises a bottom plate surrounded by an outer peripheral wall, and four mounting portions arranged at the four corners of the bottom plate and each projecting upward. Of the four mounting portions, the two front mounting portions located on the front side have lateral projections that project upward and extend in the width direction near their rear ends, and the two rear mounting portions located on the rear side have lateral projections that project upward and extend in the width direction near their front ends. Each of the four mounting portions is provided with a water passage portion that allows water to pass from the upper surface of the mounting portion toward the upper surface of the bottom plate. 【0007】 In this case, forming a lateral projection on the mounting surface prevents the washing machine's legs from shifting in the depth direction. Therefore, for example, vibrations during the spin cycle can prevent the washing machine's legs from shifting in the depth direction and causing it to fall off the mounting surface. Furthermore, if there is an area on the top surface of the mounting surface where water can accumulate, there is a possibility that water may accumulate on the top surface of the mounting surface and overflow outside the washing machine pan. However, in the washing machine pan of the present invention, a water passage is formed on the mounting surface that allows water to pass towards the top surface of the bottom plate, thereby preventing water from overflowing outside the washing machine pan. 【0008】 Preferably, each of the four mounting sections has a vertical projection that protrudes upward and extends in the depth direction. 【0009】 In this case, by forming vertical protrusions on the four mounting sections, it is possible to suppress the legs of the washing machine from shifting in the width direction. Therefore, for example, it is possible to prevent the washing machine from falling off the mounting section due to the legs shifting in the width direction caused by vibrations during the spin cycle. 【0010】 It is preferable that each of the four mounting portions has a vertical projection that protrudes upward and extends in the depth direction near the inner end in the width direction. 【0011】 In this case, for example, the vibrations during the spin cycle can cause the washing machine's legs to shift in the width direction, preventing the washing machine from falling off the mounting surface. 【0012】 It is preferable that each of the four mounting portions has a vertical projection that protrudes upward and extends in the depth direction near the outer end in the width direction. 【0013】 In this case, for example, the vibrations during the spin cycle can cause the washing machine's legs to shift in the width direction, preventing the washing machine from falling off the mounting surface. 【0014】 Each of the four mounting sections has a support section that protrudes from the upper surface of the bottom plate and a fall prevention member attached to the upper surface of the support section, and it is preferable that the lateral projection is formed on the fall prevention member. 【0015】 In this case, a fall prevention component is attached to the conventional washing machine tray, which prevents the washing machine from falling off the mounting surface due to, for example, the legs shifting in the depth direction due to vibrations during the spin cycle. 【0016】 Each of the four mounting sections has a support section that protrudes from the upper surface of the bottom plate and a fall prevention member attached to the upper surface of the support section, and it is preferable that the lateral projection and the vertical projection are formed on the fall prevention member. 【0017】 In this case, a fall prevention member is attached to the conventional washing machine tray, which prevents the washing machine from falling off the mounting surface due to vibrations during the spin cycle, for example, causing the legs to shift in the depth or width direction. 【0018】 The aforementioned fall prevention member is preferably made of metal. 【0019】 In this case, the strength of the fall prevention member can be increased, and deformation or damage to the lateral projections T1, T3 and T2, T4 can be prevented. 【0020】 A method for manufacturing a washing machine pan according to another aspect of the present invention is a method for manufacturing a washing machine pan having a bottom plate surrounded by an outer peripheral wall and four support parts arranged at the four corners of the bottom plate and each projecting upward, wherein a fall prevention member having a first projection that projects upward and extends in a predetermined direction is attached to the washing machine pan, wherein the fall prevention member is attached to the front support parts such that the first projection projects upward and extends in the width direction near the rear end of the two front support parts arranged on the front side of the four support parts, and the fall prevention member is attached to the rear support parts such that the first projection projects upward and extends in the width direction near the front end of the two rear support parts arranged on the rear side of the four support parts, wherein the water passage portion is provided in each of the four support parts to allow water to pass from the upper surface of the support part toward the upper surface of the bottom plate. 【0021】 In this case, by attaching a fall prevention member to the support part of a conventional washing machine pan, it is possible to suppress the shifting of the legs in the depth direction due to vibrations during the spin cycle of the washing machine. Therefore, it is possible to prevent the washing machine from falling from the support part due to the shifting of the legs in the depth direction due to vibrations during the spin cycle of the washing machine. In addition, if there is an area on the upper surface of the support part where water can accumulate, there is a possibility that water will accumulate on the upper surface of the support part and overflow to the outside of the washing machine pan. However, in the washing machine pan of the present invention, a water passage part is formed in the support part that allows water to pass towards the upper surface of the bottom plate, thereby preventing water from overflowing to the outside of the washing machine pan. 【0022】 The fall prevention member has a second protrusion that protrudes upward and extends in a direction substantially perpendicular to the predetermined direction. It is preferable to attach the fall prevention member to the four support portions so that the four support portions form vertical protrusions in which the second protrusion protrudes upward and extends in the depth direction. 【0023】 In this case, by forming vertical protrusions on the four support portions, it is possible to suppress the displacement of the legs of the washing machine in the width direction. Therefore, for example, it is possible to prevent the legs of the washing machine from being displaced in the width direction due to the vibration during dehydration and the washing machine from falling off the support portions. 【0024】 It is preferable to attach the fall prevention member to the four support portions so that vertical protrusions that protrude upward and extend in the depth direction are formed in the vicinity of the inner end portions in the width direction of the four support portions. 【0025】 In this case, for example, it is possible to prevent the legs of the washing machine from being displaced in the width direction due to the vibration during dehydration and the washing machine from falling off the placement portion. 【0026】 It is preferable to attach the fall prevention member to the four support portions so that vertical protrusions that protrude upward and extend in the depth direction are formed in the vicinity of the outer end portions in the width direction of the four placement portions. 【0027】 In this case, for example, it is possible to prevent the legs of the washing machine from being displaced in the width direction due to the vibration during dehydration and the washing machine from falling off the placement portion. 【0028】 The fall prevention member is preferably made of metal. 【0029】 In this case, it is possible to increase the strength of the fall prevention member and prevent the protrusions from being deformed or damaged. 【Advantages of the Invention】 【0030】 The washing machine tray according to the present invention can prevent the washing machine installed on the tray from falling off the mounting surface.

[Modes for carrying out the invention] 【0032】 (First Embodiment) Hereinafter, a washing machine pan 1 according to the first embodiment of the present invention will be described with reference to the drawings. Figure 1 is a perspective view showing a washing machine 50 installed in the washing machine pan 1 according to this embodiment. Figure 2 is a perspective view of the washing machine pan 1 shown in Figure 1. 【0033】 As shown in Figure 1, the washing machine pan 1 of this embodiment is installed at the location where the washing machine 50 will be installed and is used to mount the washing machine 50. In this embodiment, the case where the washing machine 50 is a "drum-type washing machine 50" is described, but the washing machine 50 may be of other types. 【0034】 The washing machine 50 has a box-shaped casing 51. Inside the casing 51 is an outer tub (not shown) having a substantially cylindrical inner surface. Inside the outer tub is a drum (not shown) having a substantially cylindrical inner surface for holding clothes. An opening is formed at the front end of the drum, and an annular loading port 52 is formed at the front end of the outer tub, positioned in front of the opening of the drum. The drum is pivotally supported by a main shaft extending in the front-rear direction and is rotatable around a horizontal axis. A door 53 for opening and closing the loading port 52 is provided on the front of the casing 51. 【0035】 The bottom surface of the housing 51 is provided with four legs 58 (only two legs 58 are shown in Figure 1). The legs 58 protrude downward from the bottom surface of the housing 51. Rubber or resin leg covers are attached to the tips of the legs 58 to prevent slipping, and when the washing machine 50 is installed on the washing machine pan 1, the four legs 58 come into contact with the top surface of the washing machine pan 1. 【0036】 As shown in Figure 2, the washing machine pan 1 has a bottom plate 3 surrounded by an outer wall 2 and four mounting parts 5 located at the four corners of the bottom plate 3. The four mounting parts 5 are formed to protrude upward from the upper surface of the bottom plate 3. Drainage holes 6 are formed in the bottom surface 3. When a washing machine 50 is installed on the washing machine pan 1, the four mounting parts 5 raise the washing machine 50 door to a predetermined height (height of the mounting parts 5), making it easier to load and unload clothes. In addition, by using the washing machine pan 1, a gap is formed between the bottom surface of the washing machine 50 and the washing machine pan 1, making it possible to clean the bottom of the washing machine 50. Installation of drainage piping is also made easier. 【0037】 In the following explanation, when the washing machine 50 is installed on the washing machine pan 1, the side of the washing machine 50's casing 51 on which the door 53 is provided will be referred to as the "front side," the opposite side as the "rear side," the right side when viewed from the front side will be referred to as the "right side," and the left side when viewed from the front side will be referred to as the "left side." Therefore, the two mounting sections 5 located on the front side of the four mounting sections 5 will be referred to as the "front mounting section 5A," and the two mounting sections 5 located on the rear side of the four mounting sections 5 will be referred to as the "rear mounting section 5N." Also, when viewing the washing machine 50 from the front side, the "width direction (left-right direction)" of the washing machine 50 will be referred to as the "horizontal direction." Furthermore, the "depth direction (direction from the front side to the rear side, or from the rear side to the front side)" of the washing machine 50 will be referred to as the "vertical direction." 【0038】 The two front mounting sections 5A each include a front support section 5A1 protruding from the upper surface of the base 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1. Similarly, the two rear mounting sections 5N each include a rear support section 5N1 protruding from the upper surface of the base 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1. The front support section 5A1 and the rear support section 5N1 have a rectangular parallelepiped shape with a substantially square upper surface in plan view. The fall prevention members 5A2 and 5N2 are plate-shaped members with a substantially square shape in plan view. The area of ​​the fall prevention members 5A2 and 5N2 is smaller than the area of ​​the front support section 5A1 and the rear support section 5N1. 【0039】 In this way, by attaching the two fall prevention members 5A2 to the two front support parts 5A1 respectively, a lateral projection T1 and a vertical projection T2 are formed on the upper surface of the two front support parts 5A1. The lateral projection T1 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support part 5A1. The vertical projection T2 is positioned along the inner end 5Ab in the width direction at a position away from the upper end position of the inner end 5Ab in the width direction of the front support part 5A1. Both the lateral projection T1 and the vertical projection T2 are formed in a straight shape and are positioned with almost no gap between them. 【0040】 Similarly, by attaching two fall prevention members 5N2 to two rear support parts 5N1 respectively, a lateral projection T3 and a vertical projection T4 are formed on the upper surface of the two rear support parts 5N1. The lateral projection T3 is positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support part 5N1. The vertical projection T4 is positioned along the inner end 5Nb in the width direction at a position away from the upper end position of the inner end 5Nb in the width direction of the rear support part 5N1. Both the lateral projection T3 and the vertical projection T4 are formed in a straight line shape and are positioned with almost no gap between them. 【0041】 The widthwise length of the lateral projection T1 is shorter than the widthwise length of the rear end 5Aa of the front support portion 5A1. The depthwise length of the vertical projection T2 is shorter than the depthwise length of the widthwise inner end 5Ab of the front support portion 5A1 and is positioned away from the upper end of the widthwise inner end 5Ab. Therefore, even if water accumulates above the front support portion 5A1 and the fall prevention member 5A2, the water will flow and move from a part of the rear end 5Aa of the front support portion 5A1 (the part where the lateral projection T1 is not formed) and the entire widthwise inner end 5Ab of the front support portion 5A1 toward the bottom plate 3. 【0042】 Similarly, the widthwise length of the lateral projection T3 is shorter than the widthwise length of the front end 5Na of the rear support portion 5N1. The depthwise length of the vertical projection T4 is shorter than the depthwise length of the widthwise inner end 5Nb of the rear support portion 5N1 and is positioned away from the upper end of the widthwise inner end 5Nb. Therefore, even if water accumulates above the rear support portion 5N1 and the fall prevention member 5N2, the water will flow and move from a part of the front end 5Na of the rear support portion 5N1 (the part where the lateral projection T3 is not formed) and the entire widthwise inner end 5Nb of the rear support portion 5N1 toward the bottom plate 3. 【0043】 Thus, in the washing machine pan 1, as shown in Figure 3, no protrusions are formed on a portion of the rear end 5Aa of the front support portion 5A1 and on the entire widthwise inner end 5Ab of the front support portion 5A1. Therefore, these areas become water passages C through which water can pass from the upper surface of the front mounting portion 5A toward the bottom plate 3. Similarly, no protrusions are formed on a portion of the front end 5Na of the rear support portion 5N1 and on the entire widthwise inner end 5Nb of the rear support portion 5N1. Therefore, these areas become water passages C through which water can pass from the upper surface of the rear mounting portion 5N toward the bottom plate 3. 【0044】 As described above, in the washing machine pan 1 of this embodiment, a lateral projection T1 that protrudes upward and extends in the width direction is formed near the rear end 5Aa of each of the two front mounting portions 5A, and a vertical projection T2 that protrudes upward and extends in the depth direction is formed near the inner end 5Ab in the width direction of each of the two front mounting portions 5A. In this embodiment, "near the rear end 5Aa of the front mounting portion 5A" means "the area on the rear side of the center in the depth direction of the front mounting portion 5A," and "near the inner end 5Ab in the width direction of the front mounting portion 5A" means "the area in the width direction inward of the center in the width direction of the front mounting portion 5A (the area on the side closer to the other front mounting portion 5A than the center in the width direction of one front mounting portion 5A)." 【0045】 Furthermore, in the two rear mounting sections 5N located on the rear side of the four mounting sections 5, a lateral projection T3 is formed near the front end 5Na, projecting upward and extending in the width direction, and a vertical projection T4 is formed near the inner end 5Nb in the width direction of each of the two rear mounting sections 5N, projecting upward and extending in the depth direction. In this embodiment, "near the front end 5Na of the rear mounting section 5N" means "the area on the front side of the rear mounting section 5N compared to the center in the depth direction," and "near the inner end 5Nb in the width direction of the rear mounting section 5N" means "the area in the width direction inward of the rear mounting section 5N compared to the center in the width direction of one rear mounting section 5N (the area on the side closer to the other rear mounting section 5N than the center in the width direction of one rear mounting section 5N)." 【0046】 Furthermore, since water passage sections C are provided at both the rear end 5Aa and the widthwise inner end 5Ab of the two front mounting sections 5A, and at both the front end 5Na and the widthwise inner end 5Nb of the two rear mounting sections 5N, water can pass from the upper surfaces of the front mounting sections 5A and rear mounting sections 5N toward the bottom plate 3. 【0047】 In this embodiment, the outer peripheral wall 2, bottom plate 3, front support portion 5A1, and rear support portion 5N1 are made of, for example, resin, while the fall prevention members 5A2 and 5N2 are made of, for example, metal, and can be made of stainless steel, painted carbon steel plate, or resin. 【0048】 Fall prevention members 5A2 and 5N2 are identical in shape, and as shown in Figure 4, they are both approximately square-shaped plate-like members, the fall prevention member 30. That is, by rotating the fall prevention member 30 horizontally and attaching it to the washing machine pan 1 in different orientations, it can be used for either the fall prevention member 5A2 or the fall prevention member 5N2. 【0049】 Figure 4(a) is a perspective view of the fall prevention member 30 as seen from above, and Figure 4(b) is a perspective view of the fall prevention member 30 as seen from below. As shown in Figure 4(a), the fall prevention member 30 has a substantially square-shaped flat portion 31, a projection 32 bent upward over the entire area of ​​one end of the flat portion 31, and a projection 33 bent upward over the entire area of ​​the other end of the flat portion 31. The flat portion 31 has a predetermined thickness, and its back surface is attached to the washing machine pan 1. Both the projection 32 and the projection 33 have a predetermined height and are arranged with almost no gaps between them. 【0050】 When attaching the fall prevention member 30 to the washing machine pan 1, as shown in Figure 4(b), double-sided tape 35 is used, for example, which is attached to almost the entire back surface of the flat part 31. In this case, since a heavy object such as a washing machine is supported by double-sided tape, the mass of the washing machine constantly applies good pressure to the object to which the double-sided tape is attached, allowing the double-sided tape to generate the best possible adhesive strength. In this way, since the fall prevention member 30 can be attached to the washing machine pan 1 with double-sided tape, there is no need for screws or other fasteners, making installation easy. Also, when installing in a rental property, it is easy to restore the unit to its original state by simply removing the tape. Even when replacing with a smaller washing machine, there is no need to worry about the washing machine falling, even if it barely fits in the four corners. 【0051】 Figure 5 illustrates a method for manufacturing the washing machine pan 1 of this embodiment by attaching four fall prevention members 30 to a conventional washing machine pan 10. 【0052】 A conventional washing machine pan 10, as shown in Figure 5(a), has a bottom plate 3 surrounded by an outer peripheral wall 2 and four support parts 5 positioned at the four corners of the bottom plate 3. In other words, in a conventional washing machine pan 10, the four support parts 5 consist of two front support parts 5A1 and two rear support parts 5N1. In this embodiment, "conventional washing machine pan" means a washing machine pan in which protrusions (lateral protrusions and / or vertical protrusions) for preventing the legs 58 of the washing machine 50 from falling are not formed on the upper surfaces of the four support parts 5 positioned at the four corners of the bottom plate 3. 【0053】 First, two fall prevention members 30 are attached to the upper surfaces of the two front support sections 5A1 (the left front support section 5A1 and the right front support section 5A1). In this embodiment, for example, until the fall prevention members 30 are attached to the upper surfaces of the front support sections 5A1, they may be referred to as "protrusions 32 and 33 of the fall prevention member 30," and after the fall prevention member 30 is attached to the upper surfaces of the front support section 5A1, they may be referred to as "lateral protrusion T1 and vertical protrusion T2 of the fall prevention member 5A2." 【0054】 At that time, as shown in Figure 5(b), the fall prevention member 30 is attached to the upper surface of the front support portion 5A1 such that the projection 32 of the fall prevention member 30 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support portion 5A1, and the projection 33 of the fall prevention member 30 is positioned along the inner end 5Ab in the width direction at a position away from the upper end position of the inner end 5Ab in the width direction of the front support portion 5A1. 【0055】 In contrast, for the right-side front support portion 5A1, the fall prevention member 30 is attached to the upper surface of the front support portion 5A1 such that the projection 33 of the fall prevention member 30 is positioned along the rear end portion 5Aa at the upper end position of the rear end portion 5Aa of the front support portion 5A1, and the projection 32 of the fall prevention member 30 is positioned along the inner end portion 5Ab in the width direction at a position away from the upper end position of the inner end portion 5Ab in the width direction of the front support portion 5A1. 【0056】 Furthermore, two fall prevention members 30 are attached to the upper surfaces of the two rear support sections 5N1 (the left rear support section 5N1 and the right rear support section 5N1). 【0057】 At that time, with respect to the left rear support portion 5N1, the fall prevention member 30 is attached to the upper surface of the rear support portion 5N1 such that the projection 33 of the fall prevention member 30 is positioned along the front end portion 5Na at the upper end position of the front end portion 5Na of the rear support portion 5N1, and the projection 32 of the fall prevention member 30 is positioned along the inner end portion 5Nb in the width direction at a position away from the upper end position of the inner end portion 5Nb in the width direction of the rear support portion 5N1. 【0058】 In contrast, for the right rear support portion 5N1, the fall prevention member 30 is attached to the upper surface of the rear support portion 5N1 such that the projection 32 of the fall prevention member 30 is positioned along the front end portion 5Na at the upper end position of the front end portion 5Na of the rear support portion 5N1, and the projection 33 of the fall prevention member 30 is positioned along the inner end portion 5Nb in the width direction at a position away from the upper end position of the inner end portion 5Nb in the width direction of the rear support portion 5N1. 【0059】 As shown in Figure 5(c), a lateral projection T1 and a vertical projection T2 are formed on the upper surfaces of the two front support portions 5A1, and a lateral projection T3 and a vertical projection T4 are formed on the upper surfaces of the two rear support portions 5N1, completing the washing machine pan 1 of this embodiment. 【0060】 The method for installing the washing machine 50 on the washing machine pan 1 will be explained based on Figure 6. 【0061】 When installing a washing machine 50, if there is a wall on the back side of the installation location, or if there are walls on one or both sides of the installation location, it is not possible to install the washing machine from that direction. Moreover, some washing machines weigh nearly 100 kg, making it difficult to lift such a washing machine and place it on the washing machine pan from above. Therefore, when installing a washing machine 50 on the washing machine pan 1, as shown in Figure 6(a), the washing machine 50 is lifted and tilted so that the front end of the washing machine casing 51, where the door 53 is located, is positioned towards the back from the top end to the bottom end, and the two front legs 58 of the drum-type washing machine 50 are placed on the upper surface of the two front mounting parts 5A of the washing machine pan 1. After that, it is common to gradually slide it towards the back while balancing it with the feet of the washing machine. At that time, since there are no protrusions formed on the front end and radially outer end of the fall prevention member 5A2 attached to the upper surface of the front mounting part 5A, the two legs 58 do not get in the way when gradually shifting the two legs 58 to the rear side after they have been placed on the front side of the two front support parts 5A1 of the washing machine pan 1, thus assisting in the installation process. 【0062】 For example, if a lateral projection is formed on the front end of the fall prevention member 5A2 attached to the upper surface of the front mounting portion 5A, then after placing the two legs 58 on the front portions of the two front support portions 5A1 of the washing machine pan 1, the two legs 58 must be lifted and carried to a position over the lateral projection before being placed on the fall prevention member 5A2, making the process of installing the washing machine 50 on the washing machine pan 1 extremely complicated. 【0063】 After moving the two legs 58 to the correct position on the fall prevention member 5A2, as shown in Figure 6(b), the washing machine 50 is placed in a horizontal position (not tilted) and the two legs 58 on the back of the washing machine 50 are placed on the upper surfaces of the two rear mounting parts 5NA of the washing machine pan 1. This completes the installation of the washing machine 50 on the washing machine pan 1. 【0064】 When installing the washing machine 50 on the washing machine pan 1, the four legs 58 of the washing machine 50 are positioned approximately in the center of the four fall prevention members 5A2 and 5N2, as shown in Figures 7(a), 8(a), 9(a), and 10(a). In this embodiment, the position of the washing machine 50 shown in Figures 7(a), 8(a), 9(a), and 10(a) is referred to as the "optimal position". 【0065】 (If shifted towards the front) If the washing machine 50 shifts to the front due to vibrations during, for example, a spin cycle, the position of the four legs 58 also moves to the front, as shown in Figure 7(b). At that time, the two rear legs 58 can move to the front until they come into contact with the lateral projection T3 on the rear mounting section 5N, but beyond that point, the lateral projection T3 restricts further movement to the front, preventing the washing machine 50 from moving to the front. Therefore, it is possible to prevent the two rear legs 58 from coming off the rear mounting section 5N and the washing machine 50 from falling from the four mounting sections 5. 【0066】 (If it shifts to the back side) If the washing machine 50 shifts to one side due to vibrations during, for example, a spin cycle, the position of the four legs 58 moves to the rear side, as shown in Figure 8(b). At that time, the two front legs 58 can move to the rear side until they contact the lateral projection T1 on the front mounting section 5A, but beyond that, the lateral projection T1 restricts further movement to the rear side, so the washing machine 50 will not move to the rear side. Therefore, it is possible to prevent the two front legs 58 from coming off the front mounting section 5A and the washing machine 50 from falling from the four mounting sections 5. 【0067】 (If shifted to the right) If the washing machine 50 shifts to the right due to vibrations during, for example, a spin cycle, the position of the four legs 58 moves to the right, as shown in Figure 9(b). At that time, the two left legs 58 can move to the right until they come into contact with the vertical projection T2 on the left front mounting section 5A and the vertical projection T4 on the left rear mounting section 5N. However, beyond that point, the vertical projections T2 and T4 restrict further movement to the right, preventing the washing machine 50 from moving to the right. Therefore, the two left legs 58 can detach from the left front mounting section 5A and the left rear end 5N, preventing the washing machine 50 from falling from the four mounting sections 5. 【0068】 (If shifted to the left) If the washing machine 50 shifts to the left due to vibrations during, for example, a spin cycle, the position of the four legs 58 moves to the left, as shown in Figure 10(b). At that time, the two right legs 58 can move to the left until they come into contact with the vertical projection T2 on the right front mounting section 5A and the vertical projection T4 on the right rear mounting section 5N. However, beyond that point, the vertical projections T2 and T4 restrict further movement to the left, preventing the washing machine 50 from moving to the left. Therefore, the two right legs 58 can detach from the right front mounting section 5A and the right rear end 5N, preventing the washing machine 50 from falling from the four mounting sections 5. 【0069】 As described above, the washing machine pan 1 of this embodiment comprises a bottom plate 3 surrounded by an outer peripheral wall 2, and four mounting portions 5 arranged at the four corners of the bottom plate 3 and each projecting upward. Of the four mounting portions 5, the two front mounting portions 5A located on the front side have a lateral projection T1 that projects upward and extends in the width direction near the rear end 5Aa, and the two rear mounting portions 5N located on the rear side have a lateral projection T3 that projects upward and extends in the width direction near the front end 5Na, and each of the four mounting portions 5 is provided with a water passage portion C that allows water to pass from the upper surface of the mounting portion 5 toward the upper surface of the bottom plate 3. 【0070】 In this case, by forming lateral protrusions T1 and T3 on the mounting section 5, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the depth direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling off the mounting section 5 due to the legs 58 shifting in the depth direction due to vibrations during spin-drying. In addition, if there is an area on the upper surface of the mounting section 5 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the mounting section 5 and overflow to the outside of the washing machine pan. However, in the washing machine pan 1 of this embodiment, a water passage section C is formed on the mounting section 5 that allows water to pass towards the upper surface of the bottom plate 3, thereby preventing water from overflowing to the outside of the washing machine pan 1. 【0071】 In the washing machine pan 1 of this embodiment, each of the four mounting sections 5 has vertical projections T2 and T4 that protrude upward and extend in the depth direction. 【0072】 In this case, by forming vertical projections T2 and T4 on the mounting section 5, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the width direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling off the mounting section 5 due to the legs 58 shifting in the width direction caused by vibrations during the spin cycle. 【0073】 In the washing machine pan 1 of this embodiment, vertical projections T2 that protrude upward and extend in the depth direction are formed near the inner end 5Ab in the width direction of each of the two front mounting portions 5A, and vertical projections T4 that protrude upward and extend in the depth direction are formed near the inner end 5Nb in the width direction of each of the two rear mounting portions 5N. 【0074】 In this case, for example, the vibrations during the spin cycle can cause the legs 58 of the washing machine 50 to shift in the width direction, preventing the washing machine 50 from falling off the mounting section 5. 【0075】 In the washing machine pan 1 of this embodiment, the two front mounting sections 5A each have a front support section 5A1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1, and the two rear mounting sections 5N each have a rear support section 5N1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1, and the lateral protrusions T1 and T3 are formed on the fall prevention members 5A2 and 5N2, respectively. 【0076】 In this case, the anti-fall members 5A2 and 5N2 are attached to the conventional washing machine pan 10, so that, for example, the washing machine 50 does not fall from the mounting section 5 due to the legs 58 shifting in the depth direction due to vibrations during the spin cycle. 【0077】 In the washing machine pan 1 of this embodiment, the two front mounting sections 5A each have a front support section 5A1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1, and the two rear mounting sections 5N each have a rear support section 5N1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1, and the lateral projections T1, T3 and the vertical projections T2, T4 are formed on the fall prevention members 5A2, 5N2, respectively. 【0078】 In this case, the anti-fall members 5A2 and 5N2 are attached to the conventional washing machine pan 10, so that, for example, the legs 58 of the washing machine 50 may shift in the depth direction or width direction due to vibrations during the spin cycle, preventing the washing machine 50 from falling from the mounting section 5. 【0079】 In the washing machine pan 1 of this embodiment, the fall prevention members 5A2 and 5N2 are made of metal. 【0080】 In this case, the strength of the fall prevention members 5A2 and 5N2 can be increased, and deformation or damage to the lateral projections T1, T3 and T2, T4 can be prevented. 【0081】 The method for manufacturing the washing machine pan 1 of this embodiment is to attach a fall prevention member 30 to a washing machine pan having a bottom plate 3 surrounded by an outer peripheral wall 2 and two front support portions 5A1 and two rear support portions 5N1 arranged at the four corners of the bottom plate 3 and projecting upward, the first projection having a first projection (used as a lateral projection among projections 32 and projection 33) that projects upward and extends in a predetermined direction, wherein the first projection is located near the rear end portion 5Aa of the two front support portions 5A1 arranged on the front side. The fall prevention member 30 is attached to the front support portion 5A1 such that it forms a lateral projection T1 that protrudes upward and extends in the width direction, and the fall prevention member 30 is attached to the rear support portion 5N1 such that it forms a lateral projection T3 that protrudes upward and extends in the width direction near the front end portion 5Na of the two rear support portions 5N1 located on the rear side, and the two front support portions 5A1 and the two rear support portions 5N1 are each provided with a water passage C that allows water to pass from the upper surface of the support portion toward the upper surface of the bottom plate 3. 【0082】 In this case, by attaching the fall prevention members 30 to the two front support parts 5A1 and the two rear support parts 5N1 of the conventional washing machine pan 10, it is possible to suppress the displacement of the legs 58 in the depth direction due to vibrations during spin-drying of the washing machine 50. Therefore, it is possible to prevent the washing machine 50 from falling from the two front support parts 5A1 and the two rear support parts 5N1 due to the displacement of the legs 58 in the depth direction due to vibrations during spin-drying. Furthermore, if there is an area on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 and overflow to the outside of the washing machine pan 1. However, in the washing machine pan 1 of this embodiment, water passage parts C that allow water to pass towards the upper surface of the bottom plate 3 are formed on the two front support parts 5A1 and the two rear support parts 5N1, thereby preventing water from overflowing to the outside of the washing machine pan 1. 【0083】 In the method for manufacturing the washing machine pan 1 of this embodiment, the fall prevention member 30 has a second projection (of projections 32 and 33 used as a vertical projection) that protrudes upward and extends substantially perpendicular to a predetermined direction, and the fall prevention member 30 is attached to two front support parts 5A1 located on the front side and two rear support parts 5N1 located on the rear side such that the second projection forms vertical projections T2 and T4 that protrude upward and extend in the depth direction. 【0084】 In this case, by forming vertical projections T2 and T4 on the two front support parts 5A1 and the two rear support parts 5N1, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the width direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling from the support parts due to the legs 58 shifting in the width direction due to vibrations during the spin cycle. 【0085】 In the method for manufacturing the washing machine pan 1 of this embodiment, the fall prevention member 30 is attached to the front support portion 5A1 such that a second projection forms a lateral projection T2 that protrudes upward and extends in the width direction near the inner end 5Ab of the two front support portions 5A1 located on the front side, and the fall prevention member 30 is attached to the support portion such that a second projection forms a lateral projection T4 that protrudes upward and extends in the width direction near the inner end 5Nb of the two rear support portions 5N1 located on the rear side. 【0086】 In this case, for example, the vibrations during the spin cycle can cause the legs 58 of the washing machine 50 to shift in the width direction, preventing the washing machine 50 from falling from the support. 【0087】 In the method for manufacturing the washing machine pan 1 of this embodiment, the fall prevention member 30 is made of metal. 【0088】 In this case, the strength of the fall prevention member 30 can be increased, and deformation or damage to the lateral projections T1, T3 and the vertical projections T2, T4 can be prevented. 【0089】 (Second Embodiment) A washing machine pan 101 according to a second embodiment of the present invention will be described with reference to the drawings. 【0090】 The difference between the washing machine pan 101 of this embodiment and the washing machine pan 1 of the first embodiment is that, in the washing machine pan 1 of the first embodiment, the vertical projection T2 is formed near the inner end of the front mounting portion 5A, whereas in the washing machine pan 101 of this embodiment, the vertical projection T12 is formed near the outer end of the front mounting portion 5A. The other structures of the washing machine pan 101 of this embodiment are the same as those of the washing machine pan 1 of the first embodiment, so a detailed explanation is omitted. 【0091】 As shown in Figure 11, the two front mounting sections 5A include a front support section 5A1 that protrudes from the upper surface of the base 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1. Similarly, the two rear mounting sections 5N include a rear support section 5N1 that protrudes from the upper surface of the base 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1. The front support section 5A1 and the rear support section 5N1 have a rectangular parallelepiped shape with a substantially square upper surface in plan view. The fall prevention members 5A2 and 5N2 are plate-shaped members with a substantially square shape in plan view. The area of ​​the fall prevention members 5A2 and 5N2 is smaller than the area of ​​the front support section 5A1 and the rear support section 5N1. 【0092】 In this way, by attaching the two fall prevention members 5A2 to the two front support parts 5A1 respectively, a lateral projection T1 and a vertical projection T12 are formed on the upper surface of the two front support parts 5A1. The lateral projection T1 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support part 5A1. The vertical projection T12 is positioned along the outer end 5Ac in the width direction at a position away from the upper end position of the outer end 5Ac in the width direction of the front support part 5A1. 【0093】 Similarly, by attaching two fall prevention members 5N2 to the two rear support parts 5N1 respectively, a lateral projection T3 and a vertical projection T14 are formed on the upper surface of the two rear support parts 5N1. The lateral projection T3 is positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support part 5N1. The vertical projection T14 is positioned along the outer end 5Nc in the width direction at a position away from the upper end position of the outer end 5Nc in the width direction of the rear support part 5N1. 【0094】 The widthwise length of the lateral projection T1 is shorter than the widthwise length of the rear end 5Aa of the front support portion 5A1. The depthwise length of the vertical projection T12 is shorter than the depthwise length of the widthwise inner end 5Ab of the front support portion 5A1, and is positioned away from the upper end of the widthwise inner end 5Ab. Therefore, even if water accumulates above the front support portion 5A1 and the fall prevention member 5A2, the water will flow and move from a part of the rear end 5Aa of the front support portion 5A1 (the part where the lateral projection T1 is not formed) and the entire widthwise inner end 5Ab of the front support portion 5A1 toward the bottom plate 3. 【0095】 Similarly, the widthwise length of the lateral projection T3 is shorter than the widthwise length of the front end 5Na of the rear support portion 5N1. The depthwise length of the vertical projection T4 is shorter than the depthwise length of the widthwise inner end 5Nb of the rear support portion 5N1 and is positioned away from the upper end of the widthwise inner end 5Nb. Therefore, even if water accumulates above the rear support portion 5N1 and the fall prevention member 5N2, the water will flow and move from a part of the front end 5Na of the rear support portion 5N1 (the part where the lateral projection T3 is not formed) and the entire widthwise inner end 5Nb of the rear support portion 5N1 toward the bottom plate 3. 【0096】 Thus, in the washing machine pan 101, as shown in Figure 12, no protrusions are formed on a portion of the rear end 5Aa of the front support portion 5A1 and on the entire widthwise inner end 5Ab of the front support portion 5A1. Therefore, these areas become water passages C through which water can pass from the upper surface of the front mounting portion 5A toward the bottom plate 3. Similarly, no protrusions are formed on a portion of the front end 5Na of the rear support portion 5N1 and on the entire widthwise inner end 5Nb of the rear support portion 5N1. Therefore, these areas become water passages C through which water can pass from the upper surface of the rear mounting portion 5N toward the bottom plate 3. 【0097】 As described above, in the washing machine pan 101 of this embodiment, a lateral projection T1 that protrudes upward and extends in the width direction is formed near the rear end 5Aa of each of the two front mounting portions 5A, and a vertical projection T12 that protrudes upward and extends in the depth direction is formed near the outer end 5Ac in the width direction of each of the two front mounting portions 5A. In this embodiment, "near the rear end 5Aa of the front mounting portion 5A" means "the area on the rear side of the center in the depth direction of the front mounting portion 5A," and "near the outer end 5Ac in the width direction of the front mounting portion 5A" means "the area on the outer side of the width direction of the front mounting portion 5A (the area that is further away from the other front mounting portion 5A than the center in the width direction of one front mounting portion 5A)." 【0098】 Furthermore, in the two rear mounting sections 5N located on the rear side of the four mounting sections 5, a lateral projection T3 is formed near the front end 5Na, projecting upward and extending in the width direction, and a vertical projection T14 is formed near the outer end 5Nc in the width direction of the two rear mounting sections 5N, projecting upward and extending in the depth direction. In this embodiment, "near the front end 5Na of the rear mounting section 5N" means "the area on the front side of the rear mounting section 5N that is further from the center in the depth direction," and "near the outer end 5Nc in the width direction of the rear mounting section 5N" means "the area on the outer side of the width direction of the rear mounting section 5N that is further from the center in the width direction of one rear mounting section 5N than the other rear mounting section 5N." 【0099】 Furthermore, since water passage sections C are provided at both the rear end 5Aa and the widthwise inner end 5Ab of the two front mounting sections 5A, and at both the front end 5Na and the widthwise inner end 5Nb of the two rear mounting sections 5N, water can pass from the upper surfaces of the front mounting sections 5A and rear mounting sections 5N toward the bottom plate 3. 【0100】 When installing the washing machine 50 on the washing machine pan 101, the four legs 58 of the washing machine 50 are positioned approximately in the center of the four fall prevention members 5A2 and 5N2, as shown in Figures 13(a), 14(a), 15(a), and 16(a). In this embodiment, the position of the washing machine 50 shown in Figures 13(a), 14(a), 15(a), and 16(a) is referred to as the "optimal position". 【0101】 (If shifted towards the front) If the washing machine 50 shifts to the front due to vibrations during, for example, a spin cycle, the positions of the four legs 58 also move to the front, as shown in Figure 13(b). At that time, the two rear legs 58 can move to the front until they come into contact with the lateral projection T3 on the rear mounting section 5N, but beyond that point, the lateral projection T3 restricts further movement to the front, preventing the washing machine 50 from moving to the front. Therefore, it is possible to prevent the two rear legs 58 from coming off the rear mounting section 5N and the washing machine 50 from falling from the four mounting sections 5. 【0102】 (If it shifts to the back side) If the washing machine 50 shifts to one side due to vibrations during a spin-drying cycle, for example, the position of the four legs 58 moves to the rear side, as shown in Figure 14(b). At that time, the two front legs 58 can move to the rear side until they contact the lateral projection T1 on the front mounting section 5A, but beyond that point, the lateral projection T1 restricts further movement to the rear side, preventing the washing machine 50 from moving to the rear side. Therefore, it is possible to prevent the two front legs 58 from coming off the front mounting section 5A and the washing machine 50 from falling from the four mounting sections 5. 【0103】 (If shifted to the right) If the washing machine 50 shifts to the right due to vibrations during a spin-drying cycle, for example, the position of the four legs 58 moves to the right, as shown in Figure 15(b). At that time, the two left legs 58 can move to the right until they come into contact with the vertical projection T12 on the left front mounting section 5A and the vertical projection T41 on the left rear mounting section 5N. However, beyond that point, the vertical projection T12 and T14 restrict further movement to the right, preventing the washing machine 50 from moving to the right. Therefore, the two left legs 58 can detach from the left front mounting section 5A and the left rear end 5N, preventing the washing machine 50 from falling from the four mounting sections 5. 【0104】 (If shifted to the left) If the washing machine 50 shifts to the left due to vibrations during, for example, a spin cycle, the position of the four legs 58 moves to the left, as shown in Figure 16(b). At that time, the two right legs 58 can move to the left until they come into contact with the vertical projection T12 on the right front mounting section 5A and the vertical projection T14 on the right rear mounting section 5N. However, beyond that point, the vertical projections T12 and T14 restrict further movement to the left, preventing the washing machine 50 from moving to the left. Therefore, the two right legs 58 can detach from the right front mounting section 5A and the right rear end 5N, preventing the washing machine 50 from falling from the four mounting sections 5. 【0105】 As described above, the washing machine pan 101 of this embodiment comprises a bottom plate 3 surrounded by an outer peripheral wall 2, and four mounting portions 5 arranged at the four corners of the bottom plate 3 and each projecting upward. Of the four mounting portions 5, the two front mounting portions 5A located on the front side have a lateral projection T1 that projects upward and extends in the width direction near the rear end 5Aa, and the two rear mounting portions 5N located on the rear side have a lateral projection T3 that projects upward and extends in the width direction near the front end 5Na, and each of the four mounting portions 5 is provided with a water passage portion C that allows water to pass from the upper surface of the mounting portion 5 toward the upper surface of the bottom plate 3. 【0106】 In this case, by forming lateral protrusions T1 and T3 on the mounting section 5, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the depth direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling off the mounting section 5 due to the legs 58 shifting in the depth direction due to vibrations during spin-drying. In addition, if there is an area on the upper surface of the mounting section 5 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the mounting section 5 and overflow to the outside of the washing machine pan. However, in the washing machine pan 101 of this embodiment, a water passage section C is formed on the mounting section 5 that allows water to pass towards the upper surface of the bottom plate 3, thereby preventing water from overflowing to the outside of the washing machine pan 101. 【0107】 In the washing machine pan 101 of this embodiment, each of the four mounting sections 5 has vertical projections T12 and T14 that protrude upward and extend in the depth direction. 【0108】 In this case, by forming vertical projections T12 and T14 on the mounting section 5, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the width direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling off the mounting section 5 due to the legs 58 shifting in the width direction caused by vibrations during the spin cycle. 【0109】 In the washing machine pan 101 of this embodiment, vertical projections T12 that protrude upward and extend in the depth direction are formed near the outer ends 5Ac in the width direction of the two front mounting portions 5A, and vertical projections T14 that protrude upward and extend in the depth direction are formed near the outer ends 5Nc in the width direction of the two rear mounting portions 5N. 【0110】 In this case, for example, the vibrations during the spin cycle can cause the legs 58 of the washing machine 50 to shift in the width direction, preventing the washing machine 50 from falling off the mounting section 5. 【0111】 In the washing machine pan 101 of this embodiment, the two front mounting sections 5A each have a front support section 5A1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1, and the two rear mounting sections 5N each have a rear support section 5N1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1, and the lateral protrusions T1 and T3 are formed on the fall prevention members 5A2 and 5N2, respectively. 【0112】 In this case, the fall prevention members 5A2 and 5N2 are attached to the conventional washing machine pan 10, so that, for example, the legs 58 of the washing machine 50 may shift in the depth direction due to vibrations during the spin cycle, preventing the washing machine 50 from falling from the mounting section 5. 【0113】 In the washing machine pan 101 of this embodiment, the two front mounting sections 5A each have a front support section 5A1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1, and the two rear mounting sections 5N each have a rear support section 5N1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1, and the lateral projections T1, T3 and the vertical projections T12, T14 are formed on the fall prevention members 5A2, 5N2, respectively. 【0114】 In this case, the anti-fall members 5A2 and 5N2 are attached to the conventional washing machine pan 10, so that, for example, the legs 58 of the washing machine 50 may shift in the depth direction or width direction due to vibrations during the spin cycle, preventing the washing machine 50 from falling from the mounting section 5. 【0115】 In the washing machine pan 101 of this embodiment, the fall prevention members 5A2 and 5N2 are made of metal. 【0116】 In this case, the strength of the fall prevention members 5A2 and 5N2 can be increased, and deformation or damage to the lateral protrusions T1 and T3 can be prevented. 【0117】 The method for manufacturing the washing machine pan 101 of this embodiment is to manufacture a washing machine pan 1 by attaching a fall prevention member 30 to a washing machine pan having a bottom plate 3 surrounded by an outer peripheral wall 2 and two front support portions 5A1 and two rear support portions 5N1 arranged at the four corners of the bottom plate 3 and projecting upward, the first member having a first projection (used as a lateral projection among projections 32 and projections 33) that projects upward and extends in a predetermined direction, wherein near the rear end portion 5Aa of the two front support portions 5A1 arranged on the front side, The fall prevention member 30 is attached to the front support portion 5A1 so as to form a lateral projection T1 that protrudes upward and extends in the width direction, and the fall prevention member 30 is attached to the rear support portion 5N1 so as to form a lateral projection T3 that protrudes upward and extends in the width direction near the front end portion 5Na of the two rear support portions 5N1 located on the rear side, and the two front support portions 5A1 and the two rear support portions 5N1 are each provided with a water passage C that allows water to pass from the upper surface of the support portion toward the upper surface of the bottom plate 3. 【0118】 In this case, by attaching the fall prevention members 30 to the two front support parts 5A1 and the two rear support parts 5N1 of the conventional washing machine pan 10, it is possible to suppress the displacement of the legs 58 in the depth direction due to vibrations during spin-drying of the washing machine 50. Therefore, it is possible to prevent the washing machine 50 from falling from the two front support parts 5A1 and the two rear support parts 5N1 due to the displacement of the legs 58 in the depth direction due to vibrations during spin-drying. Furthermore, if there is an area on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 and overflow to the outside of the washing machine pan 1. However, in the washing machine pan 1 of this embodiment, water passage parts C that allow water to pass towards the upper surface of the bottom plate 3 are formed on the two front support parts 5A1 and the two rear support parts 5N1, thereby preventing water from overflowing to the outside of the washing machine pan 1. 【0119】 In the method for manufacturing the washing machine pan 101 of this embodiment, the fall prevention member 30 has a second projection (of projections 32 and 33 used as a vertical projection) that protrudes upward and extends substantially perpendicular to a predetermined direction, and the fall prevention member 30 is attached to two front support parts 5A1 located on the front side and two rear support parts 5N1 located on the rear side, such that the second projection forms vertical projections T12 and T14 that protrude upward and extend in the depth direction. 【0120】 In this case, by forming vertical projections T12 and T14 on the two front support parts 5A1 and the two rear support parts 5N1, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the width direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling from the support parts due to the legs 58 shifting in the width direction caused by vibrations during the spin cycle. 【0121】 In the method for manufacturing the washing machine pan 201 of this embodiment, the fall prevention member 30 is made of metal. 【0122】 In this case, the strength of the fall prevention member 30 can be increased, and deformation or damage to the lateral protrusions T1 and T3 can be prevented. 【0123】 (Third embodiment) A washing machine pan 201 according to a third embodiment of the present invention will be described with reference to the drawings. 【0124】 The difference between the washing machine pan 201 of this embodiment and the washing machine pan 1 of the first embodiment is that, in the washing machine pan 1 of the first embodiment, a vertical projection T2 is formed on the front mounting portion 5A and a vertical projection T4 is formed on the rear mounting portion 5N, whereas in the washing machine pan 201 of this embodiment, a vertical projection T2 is not formed on the front mounting portion 5A and a vertical projection T4 is not formed on the rear mounting portion 5N. The other structures of the washing machine pan 201 of this embodiment are the same as those of the washing machine pan 1 of the first embodiment, so a detailed explanation is omitted. 【0125】 As shown in Figure 17, the two front mounting sections 5A include a front support section 5A1 that protrudes from the upper surface of the base 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1. Similarly, the two rear mounting sections 5N include a rear support section 5N1 that protrudes from the upper surface of the base 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1. The front support section 5A1 and the rear support section 5N1 have a rectangular parallelepiped shape with a substantially square upper surface in plan view. The fall prevention members 5A2 and 5N2 are plate-shaped members with a substantially square shape in plan view. The area of ​​the fall prevention members 5A2 and 5N2 is smaller than the area of ​​the front support section 5A1 and the rear support section 5N1. 【0126】 In the first embodiment, the fall prevention member 30 had a flat portion 31, a projection 32 bent upward over the entire area of ​​one end of the flat portion 31, and a projection 33 bent upward over the entire area of ​​the other end of the flat portion 31. However, the fall prevention member 30 of this embodiment has a flat portion 31 and a projection 32 bent upward over the entire area of ​​one end of the flat portion 31, and does not have a projection 33 bent upward over the entire area of ​​the other end of the flat portion 31. 【0127】 In this way, the two fall prevention members 5A2 are attached to the two front support parts 5A1, respectively, so that lateral projections T1 are formed on the upper surfaces of the two front support parts 5A1. The lateral projections T1 are positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support part 5A1. 【0128】 Similarly, by attaching the two fall prevention members 5N2 to the two rear support parts 5N1 respectively, lateral projections T3 are formed on the upper surfaces of the two rear support parts 5N1. The lateral projections T3 are positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support part 5N1. 【0129】 The widthwise length of the lateral projection T1 is shorter than the widthwise length of the rear end 5Aa of the front support portion 5A1. Therefore, even if water accumulates above the front support portion 5A1 and the fall prevention member 5A2, the water will flow and move from a part of the rear end 5Aa of the front support portion 5A1 (the part where the lateral projection T1 is not formed) and the entire widthwise inner end 5Ab of the front support portion 5A1 toward the bottom plate 3. 【0130】 Similarly, the widthwise length of the lateral projection T3 is shorter than the widthwise length of the front end 5Na of the rear support portion 5N1. Therefore, even if water accumulates above the rear support portion 5N1 and the fall prevention member 5N2, the water will flow and move from a part of the front end 5Na of the rear support portion 5N1 (the part where the lateral projection T3 is not formed) and the entire widthwise inner end 5Nb of the rear support portion 5N1 toward the bottom plate 3. 【0131】 Thus, in the washing machine pan 201, as shown in Figure 18, no protrusions are formed on a portion of the rear end 5Aa of the front support portion 5A1 and on the entire widthwise inner end 5Ab of the front support portion 5A1. Therefore, these areas become water passages C through which water can pass from the upper surface of the front mounting portion 5A toward the bottom plate 3. Similarly, no protrusions are formed on a portion of the front end 5Na of the rear support portion 5N1 and on the entire widthwise inner end 5Nb of the rear support portion 5N1. Therefore, these areas become water passages C through which water can pass from the upper surface of the rear mounting portion 5N toward the bottom plate 3. 【0132】 As described above, in the washing machine pan 201 of this embodiment, a lateral projection T1 that protrudes upward and extends in the width direction is formed near the rear end 5Aa of the two front mounting portions 5A. In this embodiment, "near the rear end 5Aa of the front mounting portion 5A" means "the area on the rear side of the center in the depth direction of the front mounting portion 5A". 【0133】 Furthermore, in the vicinity of the front end 5Na of the two rear mounting sections 5N located on the rear side among the four mounting sections 5, a lateral projection T3 is formed that protrudes upward and extends in the width direction. In this embodiment, "the vicinity of the front end 5Na of the rear mounting section 5N" means "the area on the front side of the rear mounting section 5N from the center in the depth direction." 【0134】 Furthermore, since water passage sections C are provided at both the rear end 5Aa and the widthwise inner end 5Ab of the two front mounting sections 5A, and at both the front end 5Na and the widthwise inner end 5Nb of the two rear mounting sections 5N, water can pass from the upper surfaces of the front mounting sections 5A and rear mounting sections 5N toward the bottom plate 3. 【0135】 When installing the washing machine 50 on the washing machine pan 201, the four legs 58 of the washing machine 50 are positioned approximately in the center of the four fall prevention members 5A2 and 5N2, as shown in Figures 19(a) and 20(a). In this embodiment, the position of the washing machine 50 shown in Figures 19(a) and 20(a) is referred to as the "optimal position". 【0136】 (If shifted towards the front) If the washing machine 50 shifts to the front due to vibrations during, for example, a spin cycle, the positions of the four legs 58 also move to the front, as shown in Figure 19(b). At that time, the two rear legs 58 can move to the front until they come into contact with the lateral projection T3 on the rear mounting section 5N, but beyond that point, the lateral projection T3 restricts further movement to the front, preventing the washing machine 50 from moving to the front. Therefore, it is possible to prevent the two rear legs 58 from coming off the rear mounting section 5N and the washing machine 50 from falling from the four mounting sections 5. 【0137】 (If it shifts to the back side) If the washing machine 50 shifts to one side due to vibrations during, for example, a spin cycle, the position of the four legs 58 moves to the rear side, as shown in Figure 20(b). At that time, the two front legs 58 can move to the rear side until they contact the lateral projection T1 on the front mounting section 5A, but beyond that point, the lateral projection T1 restricts further movement to the rear side, preventing the washing machine 50 from moving to the rear side. Therefore, it is possible to prevent the two front legs 58 from coming off the front mounting section 5A and the washing machine 50 from falling from the four mounting sections 5. 【0138】 As described above, the washing machine pan 201 of this embodiment comprises a bottom plate 3 surrounded by an outer peripheral wall 2, and four mounting portions 5 arranged at the four corners of the bottom plate 3 and each projecting upward. Of the four mounting portions 5, the two front mounting portions 5A located on the front side have a lateral projection T1 that projects upward and extends in the width direction near the rear end 5Aa, and the two rear mounting portions 5N located on the rear side have a lateral projection T3 that projects upward and extends in the width direction near the front end 5Na, and each of the four mounting portions 5 is provided with a water passage portion C that allows water to pass from the upper surface of the mounting portion 5 toward the upper surface of the bottom plate 3. 【0139】 In this case, by forming lateral protrusions T1 and T3 on the mounting section 5, it is possible to suppress the legs 58 of the washing machine 50 from shifting in the depth direction. Therefore, for example, it is possible to prevent the washing machine 50 from falling off the mounting section 5 due to the legs 58 shifting in the depth direction due to vibrations during the spin cycle. In addition, if there is an area on the upper surface of the mounting section 5 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the mounting section 5 and overflow to the outside of the washing machine pan. However, in the washing machine pan 201 of this embodiment, a water passage section C is formed on the mounting section 5 that allows water to pass towards the upper surface of the bottom plate 3, thereby preventing water from overflowing to the outside of the washing machine pan 201. 【0140】 In the washing machine pan 201 of this embodiment, the two front mounting sections 5A each have a front support section 5A1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5A2 attached to the upper surface of the front support section 5A1, and the two rear mounting sections 5N each have a rear support section 5N1 that protrudes from the upper surface of the bottom plate 3 and a fall prevention member 5N2 attached to the upper surface of the rear support section 5N1, and the lateral protrusions T1 and T3 are formed on the fall prevention members 5A2 and 5N2, respectively. 【0141】 In this case, the anti-fall members 5A2 and 5N2 are attached to the conventional washing machine pan 10, so that, for example, the washing machine 50 does not fall from the mounting section 5 due to the legs 58 shifting in the depth direction due to vibrations during the spin cycle. 【0142】 In the washing machine pan 201 of this embodiment, the fall prevention members 5A2 and 5N2 are made of metal. 【0143】 In this case, the strength of the fall prevention members 5A2 and 5N2 can be increased, and deformation or damage to the lateral protrusions T1 and T3 can be prevented. 【0144】 The method for manufacturing the washing machine pan 201 of this embodiment involves attaching a fall prevention member 30 to a washing machine pan having a bottom plate 3 surrounded by an outer peripheral wall 2, and two front support portions 5A1 and two rear support portions 5N1 arranged at the four corners of the bottom plate 3 and projecting upward, the first projection having a first projection (projection 32) that projects upward and extends in a predetermined direction, wherein the first projection protrudes upward near the rear end portion 5Aa of the two front support portions 5A1 arranged on the front side. The fall prevention member 30 is attached to the front support portion 5A1 so as to form a lateral projection T1 that protrudes and extends in the width direction, and the fall prevention member 30 is attached to the rear support portion 5N1 so as to form a lateral projection T3 near the front end 5Na of the two rear support portions 5N1 located on the rear side, where the first projection protrudes upward and extends in the width direction, and the two front support portions 5A1 and the two rear support portions 5N1 are each provided with a water passage C that allows water to pass from the upper surface of the support portion toward the upper surface of the bottom plate 3. 【0145】 In this case, by attaching the fall prevention members 30 to the two front support parts 5A1 and the two rear support parts 5N1 of the conventional washing machine pan 10, it is possible to suppress the displacement of the legs 58 in the depth direction due to vibrations during spin-drying of the washing machine 50. Therefore, it is possible to prevent the washing machine 50 from falling from the two front support parts 5A1 and the two rear support parts 5N1 due to the displacement of the legs 58 in the depth direction due to vibrations during spin-drying. Furthermore, if there is an area on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 where water can accumulate, there is a possibility that water will accumulate on the upper surface of the two front support parts 5A1 and the two rear support parts 5N1 and overflow to the outside of the washing machine pan. However, in the washing machine pan 201 of this embodiment, water passage parts C that allow water to pass towards the upper surface of the bottom plate 3 are formed on the two front support parts 5A1 and the two rear support parts 5N1, thereby preventing water from overflowing to the outside of the washing machine pan 1. 【0146】 In the method for manufacturing the washing machine pan 1 of this embodiment, the fall prevention member 30 is made of metal. 【0147】 In this case, the strength of the fall prevention member 30 can be increased, and deformation or damage to the lateral protrusions T1 and T3 can be prevented. 【0148】 Although embodiments of the present invention have been described above, the specific configuration of each part is not limited to the embodiments described above. 【0149】 For example, in the first embodiment described above, the lateral projection T1 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support portion 5A1, and the vertical projection T2 is positioned along the inner end 5Ab in the width direction at a position away from the upper end position of the inner end 5Ab in the width direction of the front support portion 5A1. However, the arrangement of the lateral projection T1 and the vertical projection T2 is not limited to these. For example, the lateral projection T1 may be positioned along the rear end 5Aa at a position away from the upper end position of the rear end 5Aa of the front support portion 5A1. The vertical projection T2 may be positioned along the inner end 5Ab in the width direction at the upper end position of the inner end 5Ab in the width direction of the front support portion 5A1. 【0150】 Similarly, the lateral projection T3 is positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support portion 5N1, and the vertical projection T4 is positioned along the widthwise inner end 5Nb at a position away from the upper end position of the widthwise inner end 5Nb of the rear support portion 5N1, but the arrangement of the lateral projection T3 and the vertical projection T4 is not limited to these. For example, the lateral projection T3 may be positioned along the front end 5Na at a position away from the upper end position of the front end 5Na of the rear support portion 5N1. The vertical projection T4 may be positioned along the widthwise inner end 5Nb at the upper end position of the widthwise inner end 5Nb of the rear support portion 5N1. 【0151】 In the second embodiment described above, the lateral projection T1 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support portion 5A1, and the vertical projection T12 is positioned along the outer end 5Ac in the width direction at a position away from the upper end position of the outer end 5Ac in the width direction of the front support portion 5A1. However, the arrangement of the lateral projection T1 and the vertical projection T12 is not limited to these. For example, the lateral projection T1 may be positioned along the rear end 5Aa at a position away from the upper end position of the rear end 5Aa of the front support portion 5A1. The vertical projection T12 may be positioned along the outer end 5Ac in the width direction at the upper end position of the outer end 5Ac in the width direction of the front support portion 5A1. 【0152】 Similarly, the lateral projection T3 is positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support portion 5N1, and the vertical projection T14 is positioned along the widthwise outer end 5Nc at a position away from the upper end position of the widthwise outer end 5Nc of the rear support portion 5N1, but the arrangement of the lateral projection T3 and the vertical projection T14 is not limited to these. For example, the lateral projection T3 may be positioned along the front end 5Na at a position away from the upper end position of the front end 5Na of the rear support portion 5N1. The vertical projection T14 may be positioned along the widthwise outer end 5Nc at the upper end position of the widthwise outer end 5Nc of the rear support portion 5N1. 【0153】 In the third embodiment described above, the lateral projection T1 is positioned along the rear end 5Aa at the upper end position of the rear end 5Aa of the front support portion 5A1, but the arrangement of the lateral projection T1 is not limited to this. For example, the lateral projection T1 may be positioned along the rear end 5Aa at a position away from the upper end position of the rear end 5Aa of the front support portion 5A1. 【0154】 Similarly, the lateral projection T3 is positioned along the front end 5Na at the upper end position of the front end 5Na of the rear support portion 5N1, but the arrangement of the lateral projection T3 is not limited to these positions. For example, the lateral projection T3 may be positioned along the front end 5Na at a position away from the upper end position of the front end 5Na of the rear support portion 5N1. 【0155】 In the first and second embodiments described above, the fall prevention member 30 has a first projection 32 that is bent upward over the entire area of ​​one end of the flat portion 31 and a second projection 33 that is bent upward over the entire area of ​​the other end of the flat portion 31, but is not limited to this. The fall prevention member 30 may have a first projection 32 that is bent upward over a part of the area of ​​one end of the flat portion 31 and a second projection 33 that is bent upward over a part of the area of ​​the other end of the flat portion 31. That is, the lengths of the first projection 32 and the second projection 33 may be changed arbitrarily. Also, the heights of the first projection 32 and the second projection 33 are not limited to being the same height and may be changed arbitrarily. 【0156】 In the first embodiment described above, the lateral projection T1 and the vertical projection T2 are arranged with almost no gap between them, and the lateral projection T3 and the vertical projection T4 are arranged with almost no gap between them, but the embodiment is not limited to this. For example, the lateral projection T1 and the vertical projection T2 may be arranged separately, and the lateral projection T3 and the vertical projection T4 may be arranged separately. In other words, the arrangement of the lateral projection T1 and the vertical projection T2 in the first fall prevention member 5A2, and the arrangement of the lateral projection T3 and the vertical projection T4 in the second fall prevention member 5N2 may be changed as desired. Similarly, in the second embodiment described above, the arrangement of the lateral projection T1 and the vertical projection T12 in the first fall prevention member 5A2, and the arrangement of the lateral projection T3 and the vertical projection T14 in the second fall prevention member 5N2 may be changed as desired. 【0157】 In the first to third embodiments described above, the first fall prevention member 5A2 and the second fall prevention member 5N2 are plate-shaped members that are substantially square in plan view, but are not limited to this. The shapes of the first fall prevention member 5A2 and the second fall prevention member 5N2 may be changed as desired. 【0158】 In the first embodiment described above, the lateral projection T1, the vertical projection T2, the lateral projection T3, and the vertical projection T4 are all formed in a straight line shape, but their shapes can be arbitrarily changed. The same applies to the shapes of the lateral projection T1, the vertical projection T12, the lateral projection T3, and the vertical projection T14 in the second embodiment. The same applies to the shapes of the lateral projection T1 and the lateral projection T3 in the third embodiment. 【0159】 In the first to third embodiments described above, the fall prevention member 30 is attached to the conventional washing machine pan 10 by double-sided tape 35 that is attached to substantially the entire back surface of the flat portion 31, but this is not limited to that. The method of attaching the fall prevention member 30 to the conventional washing machine pan 10 may be changed as desired. 【0160】 In the first to third embodiments described above, the washing machine pan of the present invention is manufactured by attaching the fall prevention member 30 to a conventional washing machine pan 10, but is not limited thereto. In the washing machine pan of the present invention, for example, when a washing machine pan having four mounting parts arranged at the four corners of the bottom plate and each projecting upward is manufactured, the lateral projections and / or vertical projections may be integrally formed with respect to each mounting part. 【0161】 The first to third embodiments described above describe washing machine pans for installing drum-type washing machines, but the invention is not limited to them. The present invention is applicable to washing machine pans for installing large washing machines in coin laundry stores, and is also applicable to washing machine pans for installing household washing machines. Furthermore, the type of washing machine installed in the washing machine pan of the present invention is not limited to drum-type washing machines, but may be other types of washing machines.
