JP 2008-69999 A (page 6, FIG. 1, FIG. 2)

  According to the conventional refrigerator, when the adjustment range in the height direction by the adjustment foot is widened, the shaft portion becomes long. For this reason, there is a problem in that the volumetric efficiency of the refrigerator is lowered because it is necessary to form a large space in the bottom of the main body to avoid the shaft portion extending upward. Further, if the screw lead of the shaft portion of the adjustment foot is small, the number of rotations is increased when the adjustment foot is lowered until it comes into contact with the installation surface. On the other hand, when the screw lead of the shaft portion of the adjustment foot is large, it is difficult to finely adjust the adjustment foot in contact with the installation surface. Therefore, there is a problem that convenience of the refrigerator is deteriorated.

  An object of this invention is to provide the refrigerator which can improve volumetric efficiency and convenience.

  In order to achieve the above object, a refrigerator according to the present invention includes a bottom plate that forms a bottom surface of a main body having a storage chamber, a cylindrical sleeve that is screwed on a screw hole provided in the bottom plate on an outer peripheral surface, And an adjustment foot installed on the installation surface having a shaft portion screwed to the inner peripheral surface, wherein the screw lead on the outer peripheral surface of the sleeve is smaller than the screw lead on the inner peripheral surface. Yes.

  In the refrigerator having the above-described configuration, the present invention is preferably provided with a flange that protrudes in the outer peripheral direction at the top of the shaft.

  According to the present invention, in the refrigerator configured as described above, a biasing portion that biases the collar portion downward is provided, and a lower surface of the collar portion and a surface facing the lower surface of the collar portion on the sleeve are engaged with each other. It is preferable that the engagement is released when a predetermined rotational force is applied to the shaft portion.

  Further, in the refrigerator having the above-described configuration, the sleeve includes a counterbore portion that fits the flange portion at an upper end, and a rotation prevention portion that stops the rotation of the flange portion on an inner peripheral wall of the spotlight portion. And preferred.

  In the refrigerator having the above-described configuration, it is preferable that the main body portion is inclined forward with respect to the installation surface when the adjustment foot is separated from the installation surface.

  According to the present invention, since the shaft portion of the adjustment foot is screwed to the inner peripheral surface of the sleeve that is screwed to the bottom plate of the main body portion, the adjustment foot is raised and lowered by the rotation of the shaft portion and the sleeve. For this reason, the adjustment range of the adjustment foot can be enlarged in a space-saving manner, and the volume efficiency of the refrigerator can be improved. Also, since the screw lead on the outer peripheral surface of the sleeve is smaller than the screw lead on the inner peripheral surface, the adjustment foot quickly contacts the installation surface by the rotation of the shaft, and the height of the adjustment foot is reduced by the rotation of the sleeve. Can be adjusted. Therefore, the convenience of the refrigerator can be improved.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view of the refrigerator according to the first embodiment. The refrigerator 1 includes a main body 5 having a heat insulating box 6 that forms a plurality of storage rooms. The heat insulating box 6 is formed by filling a foam heat insulating material 12 such as urethane foam between an outer box 10 formed of a coated steel plate or the like and an inner box 11 formed of a resin molded product.

  The freezer compartment 2 is formed in the upper part of the main body 2, and the refrigerator compartment 3 is arranged below the freezer compartment 2 via a partition wall 11a filled with a heat insulating material. The front surface of the freezer compartment 2 is opened and closed by a rotating door 21. Supporting portions 22 extending in the front-rear direction are provided on both side walls 2 a of the freezer compartment 2. A tray (not shown) made of a transparent resin is detachably installed on the support portion 22, and a stored item (not shown) is placed on the tray.

  An ice tray 23 and an ice storage box 24 are disposed below the support portion 22 in the freezer compartment 2. The ice storage box 24 stores the ice made in the ice tray 23.

  The front surface of the refrigerator compartment 3 is opened and closed by a rotating door 31. On both side walls 3a of the refrigerator compartment 3, a plurality of support portions 32 extending in the front-rear direction are provided so as to protrude vertically. A tray (not shown) made of a transparent resin is detachably installed on the support portion 32, and stored items are placed on the tray. In addition, a retractable storage case 35 is disposed in the lower part of the refrigerator compartment 3.

  A machine room 90 is provided below the rear part of the heat insulating box 6. A compressor 91 is disposed inside the machine room 90, and the back surface of the machine room 90 is covered with a machine room back plate 92. The refrigeration cycle is operated by driving the compressor 91, and cold air is generated. The stored item in the freezer compartment 2 is stored frozen by the cold air, and the stored item in the refrigerator compartment 3 is stored in the refrigerator.

  A pair of left and right rollers 8 are provided on the front and rear of the bottom plate 7 that forms the bottom surface of the main body 5. The roller 8 rolls on the indoor floor surface F (installation surface), and the refrigerator 1 can be moved on the floor surface F. In addition, the diameter of the front roller 8 is smaller than the diameter of the rear roller 8. Thereby, the main body 5 is tilted forward with respect to the floor surface F before the height adjustment by the height adjustment unit 40 described later.

  A pair of left and right height adjusting portions 40 are provided in front of the front roller 8 at the front end of the bottom plate 7. A decorative cover 9 detachably attached to the main body 5 is attached to the front of the height adjusting unit 40. The height adjustment unit 40 is covered with the decorative cover 9, so that the beauty of the refrigerator 1 can be improved and the collision between the user's foot and the height adjustment unit 40 can be prevented.

  FIG. 2 shows a side cross-sectional view of the front portion of the bottom plate 7 of the refrigerator 1. FIG. 3 is a side cross-sectional view of the height adjustment unit 40. 2 and 3 show a state before the height adjustment described later is performed. The height adjustment unit 40 includes a sleeve 41 and an adjustment foot 42, and the adjustment foot 42 is separated from the floor surface F.

  The sleeve 41 is formed in a cylindrical shape, and has a counterbore 41d at the upper end. A male screw 41a and a female screw 41b are formed on the outer peripheral surface and the inner peripheral surface of the sleeve 41, respectively. The male screw 41a is screwed into a screw hole 7a provided in the bottom plate 7, and the female screw 41b is arranged below the counterbore portion 41d.

  In this embodiment, the male screw 41a and the female screw 41b are formed by a double thread. The male screw 41a and the female screw 41b may be formed by a multi-thread screw or a single thread other than the double thread.

  The lead L1 (twice the pitch P1) of the male screw 41a on the outer peripheral surface of the sleeve 41 is formed smaller than the lead L2 (twice the pitch P2) of the female screw 41b on the inner peripheral surface. At this time, the lead angle of the male screw 41a is smaller than the lead angle of the female screw 41b.

  Also, retaining portions 41g and 41h are formed above and below the male screw 41a of the sleeve 41, respectively. The retaining portions 41g and 41h are formed with a diameter larger than the diameter of the male screw 41a. The retaining portion 41g is attached above the male screw 41a after the male screw 41a is screwed into the screw hole 7a. Note that the retaining portion 41h may be attached below the male screw 41a after the male screw 41a is screwed into the screw hole 7a.

  The adjustment foot 42 has a grip portion 42a that abuts against the floor surface F during height adjustment, and a shaft portion 42b that extends upward from the grip portion 42a and has a smaller diameter than the grip portion 42a. A screw portion 42c that is screwed into the female screw 41b of the sleeve 41 is formed on the outer peripheral surface of the shaft portion 42b. The upper end portion of the shaft portion 42b is provided with a flange portion 42d that protrudes in the outer peripheral direction. The collar portion 42d is formed in a size that can enter the counterbore portion 41d of the sleeve 41. The collar portion 42d prevents the shaft portion 42b from coming off from the sleeve 41.

  In the refrigerator 1 having the above configuration, when the user presses the main body 5, the roller 8 rolls on the floor surface F, and the main body 5 can be moved to a desired position in the room. At this time, the adjustment foot 42 is disposed at the upper limit position (the state shown in FIGS. 2 and 3), and the grip portion 42 a of the adjustment foot 42 is separated from the floor surface F and is in contact with the lower surface of the sleeve 41. At this time, the shaft portion 42 b projects upward from the upper surface of the sleeve 41. Further, the lower end portion of the male screw 41a of the sleeve 41 is screwed into the screw hole 7a of the bottom plate 7, and the bottom plate 7 is in contact with the retaining portion 41h.

The user removes the decorative cover 9 from the main body 5 after moving the main body 5 to a desired position. Thereafter, the user grips the grip portion 42a of the adjustment foot 42 and rotates the adjustment foot 42 in a downward direction (a clockwise direction when viewed from above). At this time, the weight of the refrigerator 1 is not added to the adjustment foot 42, the lead angle of the male screw 41a is small, and the peripheral length of the screw is long. For this reason,
The frictional force between the screw hole 7a and the male screw 41a is large, and the sleeve 41 does not rotate with respect to the screw hole 7a. On the other hand, the lead angle of the screw portion 42c is large and the peripheral length of the screw is short. For this reason, the frictional force between the screw portion 42c and the female screw 41b is small, and the shaft portion 42b rotates with respect to the female screw 41b. As a result, the adjustment foot 42 contacts the floor surface F with a small number of rotations by feeding the female screw 41b of the large lead L2. Therefore, the adjustment foot 42 can be quickly brought into contact with the floor surface F.

  FIG. 4 is a side sectional view of the height adjusting unit 40 in a state where the adjusting foot 42 is in contact with the floor surface F. When the adjustment foot 42 abuts on the floor surface F, the collar portion 42d of the shaft portion 42 is disposed in the spot facing portion 41d. When the adjustment foot 42 is in contact with the floor surface F, a load is applied to the adjustment foot 42 due to the weight of the refrigerator 1.

  When the user further rotates the grip portion 42 a of the adjustment foot 42 that is in contact with the floor surface F, the front portion of the bottom plate 7 of the main body portion 5 is lifted. At this time, the lead L1 of the male screw 41a of the sleeve 41 is smaller than the lead L2 of the female screw 41b, and the lead angle of the male screw 41a is smaller than the lead angle of the female screw 41b. For this reason, the screw portion 42c is less likely to slide with respect to the female screw 41b due to the force pressing the slope of the female screw 41b having a large lead angle in the vertical direction due to the weight of the refrigerator 1. On the other hand, due to the weight of the refrigerator 1, the force pressing the inclined surface of the screw hole 7 a having a small lead angle in the vertical direction and the direction of the rotational force applied to the sleeve 41 become nearly orthogonal. For this reason, the male screw 41a is easy to slide with respect to the screw hole 7a. Therefore, the screw portion 42c does not slide with respect to the female screw 41b, and the sleeve 41 and the adjustment foot 42 rotate integrally. Accordingly, as shown in FIG. 5, the front portion of the bottom plate 7 of the main body 5 is lifted by sliding between the screw hole 7a provided in the bottom plate 7 and the male screw 41a of the sleeve 41, so that the main body 5 is brought into a substantially horizontal state. When this happens, the user stops the rotation of the adjusting foot 42. As a result, even when the adjustment foot 42 is in contact with the floor surface F and a load is applied to the adjustment foot 42, the user can easily rotate the grip 42 a of the adjustment foot 42 to increase the height of the main body 5. Adjustments can be made.

  Note that when the adjustment foot 42 is further rotated after the main body portion 5 is in a substantially horizontal state, the bottom plate 7 comes into contact with the retaining portion 41 g of the sleeve 41. Thereafter, when the adjustment foot 42 is further rotated, the shaft portion 42b is lowered by the feeding of the female screw 41b in a state where the rotation of the sleeve 41 is stopped. And if the collar part 42d contact | abuts to the bottom face of the spot facing part 41d, rotation of the adjustment leg 42 will stop. Thereby, as shown in FIG. 6, the front part of the baseplate 7 is distribute | arranged to the upper limit position.

  At this time, since the retaining portion 41g contacts the bottom plate 7, the sleeve 41 can be prevented from coming off from the bottom plate 7. Further, since the collar portion 42d contacts the bottom surface of the spot facing portion 41d, the adjustment foot 42 can be prevented from coming off from the sleeve 41.

  As described above, the main body portion 5 can be adjusted to a substantially horizontal state by the rotation of the shaft portion 42 b and the sleeve 41. At this time, since the lead L1 of the male screw 41a on the outer peripheral surface of the sleeve 41 is smaller than the lead L2 of the female screw 41b on the inner peripheral surface, the height of the main body portion 5 can be easily finely adjusted.

  Further, since the adjustment foot 42 is moved up and down by the rotation of the shaft portion 42b and the sleeve 41, the height adjustment range of the main body portion 5 can be expanded without increasing the length of the shaft portion 42b.

  According to the present embodiment, since the shaft portion 42b of the adjustment foot 42 is screwed to the inner peripheral surface of the sleeve 11 that is screwed to the bottom plate 7 of the main body portion 5, the adjustment foot 42 is moved up and down by the rotation of the shaft portion 42b and the sleeve 41. To do. For this reason, the adjustment range of the adjustment foot 42 can be enlarged in space-saving, and the volumetric efficiency of the refrigerator 1 can be improved. Further, since the lead L1 of the male screw 41a on the outer peripheral surface of the sleeve 41 is smaller than the lead L2 of the female screw 41b on the inner peripheral surface, the adjustment foot 42 quickly becomes the floor surface F (installation surface) by the rotation of the shaft portion 42b. The height of the adjustment foot 42 can be finely adjusted by the contact and rotation of the sleeve 41. Therefore, the convenience of the refrigerator 1 can be improved.

  In addition, a collar portion 42 d that protrudes in the outer peripheral direction is provided on the upper portion of the shaft portion 42 b of the adjustment foot 42. This prevents the adjustment foot 42 from coming off the sleeve 41.

  In this embodiment, the collar portion 42d may be omitted, but it is more desirable to provide the collar portion 42d because the adjustment foot 42 can be easily prevented from coming off from the sleeve 41.

  Further, when the adjustment foot 42 is away from the floor surface F, the main body portion 5 is inclined forward with respect to the floor surface F. Thus, the main body 5 can be easily adjusted to a substantially horizontal state by simply rotating the adjustment foot 42 in the downward direction.

Second Embodiment
Next, a second embodiment of the present invention will be described. FIG. 7 shows a side sectional view of the height adjustment unit 40 of the refrigerator of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. The present embodiment differs from the first embodiment in the configuration of the collar portion 42d of the adjustment foot 42 and the counterbore portion 41d of the sleeve 41. Other parts are the same as those in the first embodiment.

  Engaging portions 41 i and 42 i are provided on the lower surface 42 f of the collar portion 42 d of the adjusting foot 42 and the bottom surface 41 f of the counterbore portion 41 d of the sleeve 41. Further, a biasing portion (not shown) such as a spring that biases the flange portion 42d downward is provided.

  FIG. 8 shows a detailed view of the engaging portions 41i, 42i. The engaging portions 41i and 42i are formed in a saw blade shape in a cross section along the circumferential direction. The engaging portion 41i of the spot facing portion 41d has inclined surfaces 41j and 41k, and the engaging portion 42i of the flange portion 42d has inclined surfaces 42j and 42k. The inclination angles of the inclined surfaces 41j and 42j with respect to the horizontal plane are larger than those of the inclined surfaces 41k and 42k, respectively.

  As shown in FIG. 6, the engaging portions 41i and 42i are engaged with each other when the bottom plate 7 is disposed at the upper limit position. When the adjustment foot 42 is rotated in the direction of arrow A (counterclockwise as viewed from above) from this state, the inclined surface 41j and the inclined surface 42j come into contact with each other and the sleeve 41 rotates together with the shaft portion 42b. Thereby, the screw hole 7a moves to the lower end part of the male screw 41a, and the bottom plate 7 can be lowered.

  When the adjustment foot 42 is rotated in the direction of raising the adjustment foot 42 (counterclockwise direction when viewed from above) from the state of FIG. 6, the rotation direction is changed from the direction of lowering the adjustment foot 42 (clockwise direction when viewed from above). The force pressing the slope of the female screw 41b having a large lead angle in the vertical direction due to the weight of the refrigerator 1 does not hinder the sliding of the screw portion 42c with respect to the female screw 41b. For this reason, there exists a possibility that only the shaft part 42b which has the screw part 42c with a large lead angle may rotate. In this embodiment, since the engaging portions 42i and 41i that engage with each other are provided on the lower surface 42f of the collar portion 42d of the adjustment foot 42 and the bottom surface 41f of the counterbore portion 41d of the sleeve 41, the sleeve 41 is rotated. Thus, it is possible to prevent the bottom plate 7 from being rapidly lowered as in the case where only the shaft portion 42b having the screw portion 42c having a large lead angle rotates.

  At this time, since the sleeve 41 is separated from the retaining portion 41g, the sleeve 41 can be rotated when the bottom plate 7 is raised again, and the height of the main body portion 5 can be easily adjusted.

  When the adjustment plate 42 is rotated in the direction of arrow A by applying a predetermined rotational force with the bottom plate 7 reaching the lower end of the male screw 41a (in contact with the retaining portion 41h), the biasing portion is attached. The lower surface 42f and the bottom surface 41f are disengaged against the force. Thereafter, when the adjustment foot 42 is rotated in the direction of raising, the adjustment foot 42 can be placed in the state shown in FIG.

  Note that the lower surface 42f of the flange portion 42d and the surface of the flange 41d on the sleeve 41 facing the lower surface 42f may be engaged with each other. For example, the upper end surface of the sleeve 41 may be opposed to the lower surface 42f of the flange portion 42d, and the upper end surface of the sleeve 41 may be formed in a cross-sectional saw blade shape. In this case, when the adjustment foot 42 is rotated in the direction of arrow B in FIG. 8 (clockwise as viewed from above) with the lower surface 42f of the collar portion 42d engaged with the upper end surface of the sleeve 41, the shaft portion 42b and the sleeve 41 can be easily rotated together to lift the bottom plate 7.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. 9 and 10 show a side cross-sectional view and a top view of the height adjustment unit of the refrigerator of the third embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, a rotation preventing portion that prevents rotation of the collar portion 42d is provided on the inner peripheral wall of the spot facing portion 41d. Other parts are the same as those in the first embodiment.

  A protrusion 42e that protrudes in the outer peripheral direction is provided on the lower surface of the flange part 42d, and a protrusion 41e that protrudes in the inner peripheral direction and contacts the protrusion 42e is provided on the inner peripheral wall of the spot facing 41d. The protrusion 41e constitutes a rotation preventing portion that prevents the flange portion 42d from rotating. In addition, the protrusion part 41e is provided in the position which engages with the protrusion part 42e when the lower surface of the adjustment leg 42 is distribute | arranged upwards predetermined amount with respect to the plane which passes through the lower end of the front and back rollers 8.

  FIG. 11 shows a cross-sectional view along the circumferential direction of the protrusions 41e and 42e. The cross-sectional shape along the circumferential direction of the protrusion 42e is formed in a triangle having a vertex at the lower end. The cross-sectional shape along the circumferential direction of the protrusion 41e is formed into a triangle having a vertex at the upper end.

  When the shaft portion 42b rotates and the inclined surface of the protruding portion 42e contacts the inclined surface of the protruding portion 41e, the flange portion 42d is prevented from rotating, and the rotational force applied to the shaft portion 42b is easily transmitted to the sleeve 41. . As a result, the adjustment foot 42 and the sleeve 41 can be easily rotated together when the main body 5 is moved up and down. Therefore, the height adjustment of the refrigerator 1 can be performed more easily.

  Moreover, the cross-sectional shape along the circumferential direction of the protrusion parts 41e and 42e is formed in the triangle which has the vertex at the upper end and the lower end, respectively. Thereby, when the collar part 42d enters the counterbore part 41d from above, the protrusion part 42e can be prevented from climbing onto the protrusion part 41e, and the protrusion part 41e can reliably prevent the collar part 42d from rotating.

  Further, when the adjustment foot 42 is installed on the floor surface F and the protrusion 42e comes into contact with the protrusion 41e, the user who rotates the adjustment foot 42 feels resistance. Thereby, the user can easily recognize that the adjustment foot 42 has been pulled out to a range in which the height of the refrigerator 1 is finely adjusted.

<Fourth embodiment>
Next, a fourth embodiment of the present invention will be described. 12 and 13 show a side cross-sectional view and a top view of the height adjustment unit of the refrigerator according to the fourth embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In this embodiment, the rotation prevention part which stops rotation of the collar part 42d is comprised by the internal peripheral wall of the spot facing part 41d. Other parts are the same as those in the first embodiment.

  In the present embodiment, the outer shape of the collar part 42d is formed in a hexagonal shape, and the horizontal sectional shape of the region surrounded by the inner peripheral wall of the spot facing part 41d is formed in a hexagonal shape that fits the collar part 42d. Thereby, the rotation prevention part which stops rotation of the collar part 42d by the internal peripheral wall of the spot facing part 41d is comprised. Since the rotational force applied to the shaft portion 42b of the adjustment foot 42 is more easily transmitted to the sleeve 41 by the rotation preventing portion, the height adjustment of the refrigerator 1 can be performed more easily.

  The counterbore part 41d and the shaft part so that the collar part 42d fits the counterbore part 41d when the lower surface of the adjustment foot 42 is disposed above the plane passing through the lower ends of the front and rear rollers 8 by a predetermined amount. The length in the vertical direction of 42b is determined.

  Further, the shaft portion 42b may descend from the state of FIGS. 2 and 3 and the lower surface of the flange portion 42d may come into contact with the upper end surface of the sleeve 41. However, after the collar portion 42d slides on the upper end surface of the sleeve 41 due to the backlash between the screw portion 42c and the female screw 41b, it can be fitted into the spot facing portion 41d.

  Further, the horizontal cross-sectional shape of the region surrounded by the outer shape of the flange portion 41d and the inner peripheral wall of the spot facing portion 41d is not limited to a hexagon, and may be a polygon other than a hexagon, an ellipse, or the like. In other words, the shape may be any shape as long as the collar portion 42d is prevented from rotating by the inner peripheral wall of the spot facing portion 41d.

  Moreover, in 1st Embodiment-4th Embodiment, although the pair of left and right height adjustment parts 40 are provided in the front part of the main-body part 5, in addition to this, a pair of left-right height is also provided in the rear part of the main-body part 5. An adjustment unit 40 may be provided.

  INDUSTRIAL APPLICATION This invention can be utilized for the refrigerator provided with the adjustment leg which adjusts height.
