Japanese Patent Application Laid-Open No. 2007-314188

By the way, water heaters have exhaust variations, and there are a plurality of types of exhaust types of exhaust pipes provided above the water heater main body. In particular, there is a large difference in shape between an exhaust type in which a tubular exhaust pipe protrudes forward from the front surface of the water heater main body and an exhaust type in which the tubular exhaust pipe protrudes rearward from the back surface of the water heater main body. For this reason, a plurality of types of top surface protective members for protecting the top surface of the hot water supply apparatus have been prepared in packing materials according to each exhaust type. If a dedicated top surface protection member is prepared for each exhaust type in this way, the types of packing materials increase accordingly, and extra manufacturing and management costs are incurred.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is capable of coping with a single type of member even when the exhaust part of a hot water supply device protrudes forward and the exhaust part projects backward. An object of the present invention is to provide a packing material for a water heater.

A packing material for a water heater according to the present invention includes:
A packing material for a hot water heater corresponding to an exhaust type in which an exhaust portion protrudes from the front or back of a substantially rectangular hot water heater main body,
an exterior member surrounding the left and right sides and the front and rear of the water heater;
a lower surface protection member that protects the lower surface of the water heater;
a top surface protection member that protects the top surface of the water heater;
a spacer member that protrudes either forward or rearward from the top surface protection member and abuts against the inner surface of the exterior member, thereby preventing the exhaust portion protruding forward or rearward of the water heater from coming into contact with the exterior member; prepared,
The top surface protection member and the spacer member are provided with an engaging portion and a to-be-engaged portion for engaging both, and the spacer member can be combined with a configuration in which the spacer member is attached in front of the top surface protection member and a configuration in which it is attached behind the top surface protection member. and

With the above configuration, the spacer member can be attached to the front or rear of the top surface protection member. Therefore, when packing an exhaust type water heater in which the exhaust portion protrudes from the front surface of the water heater main body, the spacer member is attached to the front of the top surface protection member, attached to the water heater and housed in the exterior member. . As a result, the spacer member can prevent the exhaust portion protruding forward of the water heater from coming into contact with the exterior member. On the other hand, when packing an exhaust-type water heater in which the exhaust portion protrudes from the back of the water heater main body, the spacer member is attached to the rear of the top surface protection member, attached to the water heater, and housed in the exterior member. . As a result, the spacer member can prevent the exhaust portion protruding rearward of the water heater from coming into contact with the exterior member. In this way, one type of top surface protection member and spacer member can be used for either an exhaust type in which the exhaust portion projects forward of the water heater or an exhaust type in which the exhaust portion projects rearward from the water heater. Even in the type, the exhaust part can be packed and protected so that it does not come into contact with the exterior member.

As described above, according to the configuration of the present invention, it is possible to correspond to two exhaust types with one type of top surface protection member and spacer member simply by replacing the spacer members in the front and rear. Therefore, there is no need to manufacture a dedicated top surface protection member corresponding to each exhaust type in which the position where the exhaust part protrudes in the hot water supply device is different, and it can be handled by combining one type of top surface protection member and spacer member. Moreover, the production cost and management cost of the packing material can be reduced.

In the packing material for the water heater,
The top surface protection member and the spacer member may be provided with a plurality of engaging portions and engaged portions for engaging both.
As a result, the top surface protection member and the spacer member can be more firmly engaged, and the exhaust part of the water heater can be reliably protected.

In the packing material for the water heater,
The top surface protection member and the spacer member can be configured to contact each other on at least two surfaces and to engage the contact surfaces.
Thereby, the spacer member is attached to the front or rear of the top surface protection member in a state in which movement of the top surface protection member in all directions of the front-rear direction, the left-right direction, and the up-down direction is blocked. Therefore, the set of the top surface protection member and the spacer member can be reliably secured without impairing the cushioning performance of the water heater, and the exhaust part of the water heater can be reliably protected.

Further, in the packing material for the water heater,
The top surface protection member is composed of a pair of members having a left-right symmetrical shape that are arranged on both left and right sides of the top surface of the water heater,
The spacer member is composed of a pair of symmetrical members attached to the left and right top surface protection members, respectively. and a box portion that contacts the
The engaging portion and the engaged portion between the top surface protection member and the spacer member may be provided at positions corresponding to the horizontal piece portion side and the box portion side of the spacer member, respectively.
Also in this way, the spacer member is attached to the front or rear of the top surface protection member in a state in which the top surface protection member is prevented from moving in all of the front-rear, left-right, and up-down directions. Therefore, the set of the top surface protection member and the spacer member can reliably ensure that the cushioning performance of the hot water supply device is not impaired, and can reliably protect the exhaust portion of the hot water supply device.
