JP 2009-250445 A

  However, since the former water heater is arranged at a position where the gripping portions face each other, the balance with respect to the facing direction of the gripping portions is good, but there is a problem that the balance with respect to the direction orthogonal to the facing direction is not good.

  Further, since the latter water heater is provided with a gripping portion at a point-symmetrical position with respect to the horizontal center of the casing, the diagonal direction of the casing is transported in the traveling direction during transportation. Sometimes the width required to pass the water heater must be larger than necessary.

  Therefore, an object of the present invention is to provide a water heater that can easily balance in the front-rear and left-right directions during transportation, and that can reduce the width required to pass the water heater during transportation.

  The present invention has a rectangular parallelepiped housing, a grip portion is provided on one of the four vertical surfaces along the vertical direction, and two vertical surfaces sharing a side with the one vertical surface. Further, a gripping portion is provided at a position closer to a vertical plane opposite to the one vertical plane than the one vertical plane.

  Further, the one vertical plane is a vertical plane that is a back surface facing a vertical surface that is a front surface in an installed state, and the gripping portion is a vertical surface that is the back surface, and a vertical surface and a back surface that are the front surface. It is preferably formed in two vertical planes that face the direction intersecting the vertical plane and become the side surfaces.

  ADVANTAGE OF THE INVENTION According to this invention, it is easy to balance in the front-back, left-right direction at the time of conveyance of a water heater, and can suppress the width | variety required to let a water heater pass through at the time of conveyance.

The right view of the water heater based on one Example of this invention is shown. The rear view of the water heater based on one Example of this invention is shown. The top view of the state which conveys the water heater based on one Example of this invention is shown. The disassembled perspective view of the water heater based on one Example of this invention is shown. The expanded view of the kick member used for the water heater which concerns on one Example of this invention is shown.

  Hereinafter, an embodiment of a water heater according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the water heater according to the present embodiment has a rectangular parallelepiped housing. One vertical surface 3 of the four vertical surfaces 1, 2a, 2b, 3 along the vertical direction is provided with a grip portion 4a, and the two vertical surfaces 2a, 2b sharing the sides with the vertical surface 3 are provided. Are provided with gripping portions 4b and 4c at positions closer to the vertical surface 1 opposed to the vertical surface 3 than to the vertical surface 3, respectively.

  Therefore, it is easy to balance in the front-rear and left-right directions during transportation of the water heater, and the width required for passing the water heater during transportation can be kept small. Therefore, for example, as shown in FIG. 2, transportation can be easily performed even in a small space such as a corner of the site.

  By the way, as shown in FIG. 2, as a positional relationship between the water heater and the transporter during transportation, one of the transporters is positioned on the vertical surface 3 side and grips the grip portion 4 a of the vertical surface 3. It is conceivable that the transporter is positioned on the side of the vertical surface 1 facing the vertical surface 3 and grips the grip portions 4b and 4c of the vertical surfaces 2a and 2b. In this case, it is easy to balance in the front-rear and left-right directions, and since the facing direction of the vertical surface 3 and the vertical surface 1 facing the vertical surface 3 is the traveling direction, the water heater is passed during transportation. The required width is small. In FIG. 2, the vertical surface 3 side is the front side in the traveling direction, but conversely, the vertical surface 1 side may be the front side in the traveling direction.

  In addition to this positional relationship, one of the transporters is positioned on the side of the vertical surface 2a to grip the grip portion 4a of the vertical surface 3 and the grip portion 4c of the vertical surface 2a, and another transporter is the vertical surface 2b. It is conceivable that the grip portion 4a of the vertical surface 3 and the grip portion 4b of the vertical surface 2b are gripped. Even in this case, it is easy to balance in the front-rear and left-right directions, and the opposing direction of the opposing vertical surfaces 2a, 2b is the traveling direction, so the width required to pass the water heater during transportation is small. That's it.

  Specifically, the vertical surface 1 is a vertical surface (see FIG. 1B) that is the front in the installed state, and the vertical surface 3 is a vertical surface that is the back in the installed state (FIG. 1D). Reference). Further, the two vertical surfaces 2a and 2b facing the direction perpendicular to the vertical surface 1 serving as the front surface and the vertical surface 3 serving as the back surface are side surfaces (see FIGS. 1A and 1C). That is, the grip portions 4a, 4b, and 4c are formed on the vertical surface 3 serving as the back surface and the two vertical surfaces 2a and 2b serving as the side surfaces.

  According to this structure, since the grip portion is not provided on the vertical surface 1 side that is the front surface, aesthetics can be improved. In addition, it is not essential to provide a structure that supports the weight of the water heater on the vertical surface 1 side that is the front surface by not providing the grip portion on the vertical surface 1 side that is the front surface (however, it may be additionally provided). ), The vertical surface 1 as the front surface can be effectively utilized as a surface for maintenance. That is, it is possible to improve the degree of freedom in designing the arrangement of piping and functional components such as valves on the front vertical surface 1 side.

  In general, the front vertical surface 1 is called a front cover, and of the two vertical surfaces 2a and 2b that are side surfaces, the right side with respect to the vertical surface 1 is called a right cover. The left side with respect to 1 is called the left hip, and the vertical plane 3 which is the back is called the rear hip.

  Here, the water heater has a width of 550 mm, a depth of 660 mm, and a height (including legs) of 2185 mm. Accordingly, when the water heater is transported, the water heater is located on the back surface (ie, the vertical surface 3) side, which is the short side of the casing, and the other transporter is located on the front surface (ie, the vertical surface 1) side. If the machine is lifted, the passing width of the water heater during transportation can be further reduced.

  This will be described in detail. In general, a water heater is transported in a state where one of the transporters has a top surface (top cover) 6 and the other has a product leg 7 and the water heater is turned down. However, since the height is larger with respect to the width and depth, there is a problem that it is difficult to change the direction in a place where the space is small, such as the corner of the site shown in FIG. In particular, it is very difficult to change the direction of a water heater having a height as compared with a normal water heater (height of about 1700 mm) like the water heater of the present embodiment. In this regard, according to the water heater of the present embodiment, the water heater can be transported in a standing state as in the installed state without being transported with the water heater being brought down.

  Further, among the gripping portions 4a, 4b, and 4c, at least the gripping portions 4b and 4c on the vertical surfaces 2a and 2b are provided at positions facing each other. Specifically, the grips 4b and 4c are provided at substantially the same height. Moreover, each holding | gripping part 4b, 4c is provided in the substantially the same position of the depth direction. Preferably, the grip portion 4a of the vertical surface 3 is also provided at substantially the same height as the grip portions 4b and 4c of the vertical surfaces 2a and 2b. And each holding | grip part 4a, 4b, 4c is provided in the average height (for example, 620 mm) which a carrier tends to exhibit force, when raising a water heater.

  Each grip part 4a, 4b, 4c is demonstrated in detail using FIG.3 and FIG.4.

  First, the holding portions 4b and 4c of the vertical surfaces 2a and 2b serving as the side surfaces are provided as concave portions formed toward the inside of the housing. Specifically, the grip portions 4b and 4c of the vertical surfaces 2a and 2b serving as the side surfaces are configured by a grip member 10 having a concave shape. Further, holes 2c and 2d for accommodating the gripping member 10 are formed in the vertical surfaces 2a and 2b serving as the side surfaces.

  By the way, in the water heater, in order to secure a space for connecting the piping, the retreating part S retreated from the front vertical surface 1 side toward the back vertical surface 3 side (that is, rearward in the depth direction). Is provided. And the holding | grip parts 4b and 4c of the vertical surfaces 2a and 2b used as the said side surface are provided above this retreating part S. As shown in FIG. Thereby, it is possible to prevent deformation of the vertical surfaces 2a and 2b serving as side surfaces. Further, the grip portions 4b and 4c of the vertical surfaces 2a and 2b serving as the side surfaces are provided at positions straddling the corners of the retreat portion S in the depth direction.

  The retreating part S is generally called a kick and is defined by the kick member 5. The kick member 5 is connected to the vertical surface 1 serving as the front surface, the vertical surfaces 2a and 2b serving as the side surfaces, the vertical surface 3 serving as the back surface, and the bottom surface 9.

  As shown in FIG. 4, the kicking member 5 has a main body 5 a having an L shape in a side view, and the main body includes a vertical portion 5 b along the vertical direction and a horizontal portion 5 c along the horizontal direction. Composed. The horizontal portion 5c is formed with a hole 5d through which piping is passed. Further, the kick-in member 5 extends along the vertical surfaces 2a and 2b serving as side surfaces and extends upward in the vertical direction from the main body 5a, and along the vertical surfaces 2a and 2b serving as side surfaces and from the main body 5a. And a rear extension 5f extending rearward in the depth direction. Specifically, the upward extending portion 5e is provided so as to protrude from the horizontal portion 5c of the main body.

  A hole 5g for accommodating the gripping member 10 is formed in the upward extending portion 5e. When the casing is assembled, holes 2c and 2d provided in the vertical surfaces 2a and 2b serving as the side surfaces of the gripping member 10, and holes 5g and 5g of the upward extending portion 5e of the kicking member 5 Is inserted.

  According to the above configuration, the load applied from the grip portions 4 b and 4 c of the vertical surfaces 2 a and 2 b serving as the side surfaces when the hot water heater is lifted is transmitted to the bottom surface 9 through the kick member 5. Therefore, since the load applied to the vertical surfaces 2a and 2b serving as the side surfaces when the water heater is lifted is reduced or eliminated, deformation of the vertical surfaces 2a and 2b serving as the side surfaces can be satisfactorily prevented.

  Next, two gripping portions 4a are provided on the vertical surface 3 serving as a back surface. Each grip 4a is provided on both sides of the center in the width direction of the vertical surface 3 serving as a back surface. Specifically, each grip portion 4a is disposed at a position where the distance from the end edge portion is equal.

  Moreover, the said holding | grip part 4a is provided as a recessed part formed toward the inside of a housing | casing. Specifically, the grip portion 4a of the vertical surface 3 serving as the back surface is configured by a grip member 10 having a concave shape. Further, a hole 3a for accommodating the gripping member 10 is formed in the vertical surface 3 serving as the back surface.

  Further, the water heater is provided with a reinforcing member 8 corresponding to the hole 3a of the vertical surface 3 serving as the back surface. The reinforcing member 8 is fixed to the vertical surface 3 serving as a back surface. The reinforcing member 8 is also formed with a hole 8a corresponding to the hole 3a of the vertical surface 3 serving as the back surface.

  According to the above configuration, the load applied from the grip portion 4a of the vertical surface 3 serving as the back surface when the water heater is lifted is distributed and transmitted to the vertical surface 3 serving as the back surface via the reinforcing member 8. Therefore, since the load applied to the vertical surface 3 serving as the back surface when the water heater is lifted is reduced, the deformation of the vertical surface 3 serving as the back surface can be favorably prevented.

  The reinforcing member 8 may be connected to the bottom surface 9. In this way, when the water heater is lifted, the load applied from the grip portion 4a of the vertical surface 3 serving as the back surface is transmitted to the bottom surface 9. Accordingly, since the load applied to the two vertical surfaces 2a and 2b serving as the side surfaces when the water heater is lifted is reduced or eliminated, the deformation of the vertical surface 3 serving as the back surface can be satisfactorily prevented.

  As mentioned above, although the hot water heater of a present Example was demonstrated, this invention is not limited to the structure described in the said Example, The structure can be changed suitably in the range which does not deviate from the meaning. .

  For example, the shape of each gripping portion 4a, 4b, 4c is not limited to the shape of the above-described embodiment, and may be a shape protruding outward from the housing. In this case, it is preferable that the grip portion is provided so as not to interfere with the wall of the building when turning around the corner of the site.

  Moreover, the shape of each holding | gripping part 4a, 4b, 4c may be comprised by the groove | channel. And only one gripping part 4a may be provided.

2a, 2b Vertical plane (vertical plane as side)
3 Vertical plane (vertical plane on the back)
