Description

  The present invention relates to a leg attachment structure for attaching a leg to a bottom plate that is detachably disposed on a main body of an apparatus such as a refrigerator or an ice making machine.

  For example, in an ice making machine, a bottom plate is detachably disposed on a lower surface of a main body that opens downward, and a plurality of legs are provided on the lower surface of the bottom plate so as to define a required gap with an installation floor surface. Is detachably disposed. The leg has a screw shaft at its upper end, and is attached to the bottom plate by screwing the screw shaft into a screw hole formed in the bottom plate or a welded nut.

  Here, the design and material of the leg vary depending on the user's preference and the like, and there are various types. However, as described above, in the structure in which the screw hole is directly formed in the bottom plate or the nut is welded, it is set in advance. It was difficult to change the legs after the product was shipped to match the screw size. Therefore, the user has no choice but to select a screw-sized leg corresponding to the screw hole or nut formed in the bottom plate, and it is pointed out that the leg design and material that can be selected are limited.

  In addition, for example, in the US, inch screws are used, and in Japan and Europe, metric screws are used, so the size of the screw holes formed in the bottom plate and the size of the nuts to be welded are matched to the screw sizes of the legs at the destination. It was necessary to change, and there was a troublesome task of dividing the processing of the bottom plate for each destination.

Therefore, a mounting member that can be attached to and detached from the bottom plate is configured to be detachable on the bottom surface of the bottom plate, and the processing applied to the bottom plate can be made common by replacing it with a mounting member that matches the screw size of the leg. (For example, refer to Patent Document 1).
JP-A-4-103585

  However, in the configuration of Patent Document 1, a screw hole for attaching the attachment member to the bottom plate must be formed in the bottom plate, which increases the number of processing steps and requires a large number of screws, leading to an increase in cost. Further, in order to fix the mounting member, it is necessary to provide a reinforcing plate on the upper surface side of the bottom plate, and the number of parts is further increased.

  Before attaching the legs to the ice making machine, the bottom plate of the ice making machine is placed directly on the floor. At this time, the load of the entire ice making machine is applied to the mounting member, so the mounting member only supports the ice making machine. Sufficient strength is required, which also increases costs.

  That is, the present invention has been proposed in view of the above-mentioned problems inherent in the prior art described above, and has been proposed to suitably solve this problem. The leg mounting structure can be easily replaced at a low cost. The purpose is to provide.

In order to overcome the above-mentioned problems and achieve the desired purpose suitably, the leg mounting structure according to the present invention is:
A leg mounting structure that is detachably disposed on the lower surface of the main body that opens downward and detachably mounts the legs to the lower surface of the bottom plate that defines the machine room inside.
An attachment plate having a fixing portion to which the legs are detachably fixed is configured to be detachably sandwiched between the bottom plate and the main body.

  According to the leg mounting structure according to the first aspect of the present invention, the leg can be easily changed by simply replacing the mounting plate sandwiched between the bottom plate and the main body. Moreover, since it is not necessary to process the screw holes for disposing the mounting plate on the bottom plate, the number of processing steps can be reduced, and the use of screws can be omitted, thereby reducing the cost. Further, since the load of the apparatus can be supported by the bottom plate, the mounting plate is not required to have high strength, and the cost can be further reduced.

  According to the leg mounting structure of the second aspect of the present invention, the size of the through hole applied to the bottom plate may be set larger than the maximum screw size in the destination leg, and the processing applied to the bottom plate is changed according to the destination. There is no problem, and the processing time can be reduced.

  Next, the leg mounting structure according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments. In the embodiment, an ice making machine will be described as an apparatus adopting the leg mounting structure, but a refrigerator or a freezer may be used as long as the machine room is internally defined by the bottom plate and the main body.

  As shown in FIG. 1, an ice making machine employing the leg mounting structure according to the embodiment includes an ice making mechanism in a main body 16 formed in a box shape by combining a plurality of panels 10, 12, 14, and 14. And a stocker (both not shown) are housed and disposed, and a bottom plate 18 is detachably disposed on the lower surface of the main body 16. The structure of the main body 16 will be described in more detail. The left and right side panels 14 and 14 constituting the main body 16 extend below the front panel 10 and the rear panel 12 by a predetermined length. Each side panel 14 is formed so that the four edges are bent inward, and the lower bent edge portion 14a is placed on the upper surface of the bottom plate 18 via a mounting plate 26 described later. It has become. The front and rear bent edges 14b of the side panel 14 are respectively formed with extended portions 14c that extend downward from the lower bent edge 14a, and the extended portions 14c penetrate through the front and rear. Each through hole 14d is formed. In addition, the separation dimension of the extending portions 14c and 14c that are separated from each other in the front and rear direction of the side panel 14 is set to be substantially the same as the front and rear dimension of the bottom plate 18, and when the side panel 14 is placed on the bottom plate 18, The extending portions 14 c and 14 c are configured to contact the front and rear end surfaces of the bottom plate 18.

  The bottom plate 18 has a required thickness and is formed in a rectangular plate shape having sufficient strength to support the load of the ice making machine. Screw holes 18a are respectively screwed at positions corresponding to the through holes 14d and 14d. That is, the lower bent edges 14a, 14a of the side panels 14, 14 of the main body 16 are positioned on the front and back of the bottom plate 18 with the mounting plates 26, 26 placed on the upper surface of the bottom plate 18. The main body 16 and the bottom plate 18 are fixed by screwing the united screws 20 inserted from the outside into the through holes 14d of the extending portions 14c into the corresponding screw holes 18a of the bottom plate 18, respectively.

  In the state where the main body 16 and the bottom plate 18 are fixed, the opening that opens to the front and rear is closed by a front plate and a back plate (both not shown) that are detachably disposed on the main body 16. Thus, a machine room 22 is internally defined between the main body 16 and the bottom plate 18. And in this machine room 22, various components which comprise the cooling unit 30 mentioned later are accommodated and arrange | positioned. It is configured that maintenance such as inspection and replacement of various parts arranged in the machine room 22 can be performed by removing the front plate from the main body 16 and opening the opening.

  Between the main body 16 and the bottom plate 18, a pair of attachment plates 26, 26 for attaching a plurality of (four in the embodiment) legs 24 to the lower surface of the bottom plate 18 are sandwiched between the left and right side portions. . Each mounting plate 26 has a substantially rectangular main body portion 26a whose front-rear dimension is set slightly shorter than the front-rear dimension of the bottom plate 18, and an edge extending in one longitudinal direction of the main body portion 26a. It is basically composed of a positioning piece 26b bent at a right angle downward. The mounting plate 26 is positioned with respect to the bottom plate 18 by bringing the positioning pieces 26b into contact with the corresponding side surfaces of the bottom plate 18 in a state where the main body portion 26a is placed on the upper surface of the bottom plate 18. . A through hole 26c is formed in the main body 26a of the mounting plate 26 so as to penetrate up and down at the front and rear end positions (positions corresponding to the corners of the bottom plate 18) and corresponds to the through holes 26c. A nut 28 as a fixing portion is welded to the upper surface of the main body (see FIG. 2). The inner diameter of the through hole 26 c is set larger than the screw hole of the nut 28. Further, the mounting plate 26 removes each unitary screw 20 that fixes the main body 16 and the bottom plate 18 and moves the main body 16 to the bottom plate 18 by a predetermined height (a height obtained by adding the thickness of the main body portion 26a and the nut 28). By lifting, the mounting plate 26 can be pulled out outward.

  In the bottom plate 18, through holes 18 b penetrating vertically are formed at the four corners corresponding to the arrangement positions of the nuts 28 in the respective mounting plates 26. The inner diameter of the through-hole 18b is set to a dimension that can correspond to the maximum screw size of various legs on the market. The leg 24 has a screw shaft 24a extending to the upper end thereof at a predetermined length. As shown in FIG. 2, the screw shaft 24a is inserted into the through hole 18b of the bottom plate 18 and the through hole 26c of the mounting plate 26 from below. The leg 24 is fixed to the lower surface of the bottom plate 18 by being inserted and screwed into the nut 28.

  As shown in FIG. 3, a condenser 32, a wind tunnel 34, a condenser fan 36 and a compressor (not shown) constituting the cooling unit 30 are sequentially arranged on the top surface of the bottom plate 18 in the front-rear direction. . The condenser 32 is configured by arranging a plurality of fins between a pair of left and right support plates 38, and mounting portions 40, 40 formed at the lower ends of both support plates 38, 38 are provided on the upper surface of the bottom plate 18. It is placed on the provided base 42 and is detachably fixed via screws 44 and 44. The mounting portion 40 of each support plate 38 is formed in a U-shaped cross section that opens toward the inside. A tool through hole 40a is formed in the upper plate, and a screw passage is formed in the lower plate. A hole 40b is formed. Then, the screw 44 inserted through the screw through hole 40b from above is screwed into the screw hole 42a screwed at the corresponding position of the base 42 using a tool such as a screwdriver inserted through the tool through hole 40a. As a result, the condenser 32 is fixed to the base 42.

  A space S having a predetermined size facing the lower side of the condenser 32 is defined between the mounting portions 40 and 40. The drain S is accommodated in the space S when the condenser 32 is washed, and is washed with water. Can accept. Further, screws 44, 44 for fixing the condenser 32 to the base 42 are set so as to face different positions on the left and right support plates 38, 38, and heads projecting to the space S side of both screws 44, 44. When the drain pan 46 is placed on the drain pan 46, the drain pan 46 is inclined downward toward the side where the drain port 46a is formed. In the embodiment, the screw 44 for fixing the right support plate 38 is positioned on the rear side, whereas the screw 44 for fixing the left support plate 38 is set on the front side and is mounted on both screws 44, 44. The drain pan 46 placed is inclined downward so that the corner on the right front side is the lowest end, and a drain outlet 46a is formed at this position. In other words, the wash water received by the drain pan 46 efficiently flows toward the drain port 46a.

(Effects of Example)
Next, the operation of the leg mounting structure according to the above-described embodiment will be described. When assembling the main body 16, the bottom plate 18 and the legs 24 of the ice making machine, first, the main body portions 26a of the mounting plates 26 are placed on the upper surfaces of the left and right ends of the bottom plate 18, and the positioning pieces 26b are handled. Are placed in contact with the side surfaces. At this time, in each mounting plate 26, the through holes 26c, 26c formed in the main body portion 26a and the through holes 18b, 18b formed in the bottom plate 18 are positioned so as to be aligned in the vertical direction.

  The main body 16 is mounted such that the lower bent edge portions 14a, 14a of the side panels 14, 14 are mounted on the main body portions 26a, 26a of the mounting plates 26, 26 mounted on the bottom plate 18. Put. In this state, the unitary screw 20 inserted from the outside into the through hole 14d of the extending portion 14c in each side panel 14 is screwed into the corresponding screw hole 18a of the bottom plate 18 so that the main body 16 and the bottom plate 18 are The pair of mounting plates 26, 26 are fixed in a state of being sandwiched from above and below. When the main body 16 and the bottom plate 18 are fixed, if the main body portion 26a and the bottom plate 18 of the mounting plate 26 are bonded in advance with a double-sided tape or the like, the positional displacement of the mounting plate 26 is fixed during the fixing operation. Can be prevented.

  As for the leg 24, as shown in FIG. 2, the screw shaft 24a is inserted into the through hole 18b and the through hole 26c from the lower side of the bottom plate 18 and screwed into the nut 28, whereby the leg 24 is It is fixed to the lower surface of the bottom plate 18.

  The mounting plate 26 can be removed by lifting the main body 16 from the bottom plate 18 by a predetermined height while removing the legs 24 and 24 and removing all the united screws 20 fixing the main body 16 and the bottom plate 18. Can be removed. That is, if a plurality of types of mounting plates 26 welded with nuts 28 having different screw sizes are prepared, the legs 24 having a design and material suitable for the user's preference are replaced with mounting plates 26 corresponding to the screw sizes. This can be easily adopted, and the degree of freedom in selecting the legs 24 is increased. Further, the processing applied to the bottom plate 18, that is, the size of the screw hole 18 a and the through hole 18 b for fixing to the main body 16 can be made common, and it is not necessary to divide the processing according to the destination, thereby reducing the processing cost. be able to. For example, the inner diameter of the through hole 18b may be set to a size that can accommodate both inch screws and metric screws.

  In addition, since the load of the ice making machine is not directly applied to the mounting plate 26, the mounting plate 26 does not require high strength, can reduce the material cost, and has a large number of stocks. It will not be a big expense. In addition, by arranging the mounting plate 26 on the upper surface of the bottom plate 18, the mounting plate 26 itself also serves as a reinforcing plate, and the overall strength can be improved without using a dedicated reinforcing plate.

  Also, the user can easily replace the leg 24. That is, many heavy components such as a compressor and a condenser 32 are installed on the bottom plate 18. In the embodiment, the mounting plate 26 can be replaced by lifting the main body 16 with respect to the bottom plate 18. The burden on the operator is light. Moreover, since the mounting plate 26 is not required to have high strength, the mounting plate 26 is thin, and even if the main body 16 is separated from the bottom plate 18 to the extent that the mounting plate 26 is removed, no excessive force is applied to the piping system in the cooling unit 30.

  Next, when the condenser 32 is to be cleaned while being disposed inside the machine chamber 22, the drain pan 46 is inserted into the space S defined in the mounting portions 40, 40 of the both support plates 38, 38. Then, it is allowed to face below the condenser 32. If the condenser 32 is washed in this state, the washing water is received by the drain pan 46, and wetting of the bottom plate 18 and the like is suppressed.

  As described above, since the mounting portions 40 and 40 of the pair of support plates 38 and 38 that define the space S that accommodates the condenser 32 are formed in a U shape, the lower end of the support plate 38 is formed in a step shape. The installation space can be reduced as compared with the case of doing so. The drain pan 46 accommodated in the space S is placed on the heads of the screws 44, 44 for fixing the condenser 32 to the base 42, so that the drain pan 46 is inclined downward toward the drain port 46a. . Accordingly, the wash water received by the drain pan 46 flows smoothly toward the drain port 46a, and the drainage performance is improved.

[Example of change]
In the above-described embodiment, the nut 28 into which the screw shaft 24a of the leg 24 is screwed is described as being welded to the mounting plate 26. However, a screw hole as a fixing portion into which the screw shaft 24a of the leg 24 can be screwed is attached. It may be formed directly on the plate 26. Further, if the front panel 10 and the rear panel 12 constituting the main body 16 extend downward from the side panel 14, the mounting plates 26 and 26 may be mounted on the front and back of the bottom plate 18. That is, any configuration may be used as long as the mounting plate 26 is placed on each of a pair of opposed edge portions of the bottom plate 18. Further, it is possible to adopt a configuration in which an attachment plate provided with one fixed portion is individually sandwiched between the main body 16 and the bottom plate 18 corresponding to the attachment position of each leg 24. The positioning piece 26b for positioning the mounting plate 26 with respect to the bottom plate 18 does not have to be formed over the entire length of one edge of the main body 26a, and may be formed partially. .

  In the said Example, although the structure which inserts the drain pan 46 in the space S defined in the lower part of the condenser 32 so that insertion / removal was employ | adopted was demonstrated as a treatment structure of the washing water at the time of washing | cleaning the condenser 32, it demonstrated. For example, the configuration shown in FIG. 4 can be employed. Note that the same reference numerals are given to the same members already described.

  That is, in the modification shown in FIG. 4, a tray-like washing drainage dish 48 whose internal dimensions are set to a size that can accommodate the condenser 32 is provided on the upper surface of the bottom plate 18 via a plurality of screws 50. And is detachably fixed. Each of the pair of support plates 52, 52 constituting the condenser 32 is formed with a mounting piece 52a bent at a right angle toward the outside at the lower end thereof, and the mounting piece 52a is washed and drained. It is fixed by being fastened together with the screw 50 while being placed on the inner upper surface of 48. That is, since the lower part of the condenser 32 is entirely inside the washing drain tray 48, all the washing water when the condenser 32 is washed can be received by the washing drain tray 48, and the bottom plate 18 Wetting is suppressed.

  A drainage hole 48a is drilled in front of the position where the condenser 32 is disposed in the washing drainage tray 48, and a drainage through hole 54 is drilled in a position corresponding to the drainage hole 48a in the bottom plate 18. The cleaning water received in the cleaning drain pan 48 is configured to be discharged below the bottom plate through the drain hole 48 a and the drain through hole 54. The drainage through hole 54 formed in the bottom plate 18 is a launch hole directed downward.

  In the washing water treatment structure for a condenser according to the modified example, when washing the condenser 32 while being disposed inside the machine chamber 22, a drain pan 46 is inserted below the bottom plate 18, It faces the drainage through hole 54. At this time, since the drainage hole 48a of the washing drainage tray 48 is formed at a position where it can be seen from the front side of the machine room 22, the drain pan 46 can be surely faced below the drainage through hole 54 of the bottom plate 18, and the washing Water does not leak to the floor. Since the washing drain pan 48 is permanently installed in the lower part of the condenser 32, the inside of the washing drain tray 48 is dried in a short time by the wind exchanged with the condenser 32 during the operation of the ice making machine after washing, Can be kept hygienic.

  Since the bottom plate 18 only needs to have a small drainage hole 54 for discharging the washing water received by the washing drainage tray 48, the strength of the bottom plate 18 is not lowered. Further, since the drainage through hole 54 is a discharge hole directed downward, water drainage is good and hygienic. Further, the drainage through hole 54 is set to the minimum necessary size, so that insects and the like do not enter the inside, and it is not necessary to provide an extra cover, so that the cost can be reduced.
