By the way, water heaters have various exhaust variations, and there are a plurality of types of exhaust pipes provided above the main body of the water heater. In particular, the shapes of the exhaust type in which the cylindrical exhaust pipe protrudes forward from the front of the water heater main body and the exhaust type in which the cylindrical exhaust pipe protrudes rearward from the back of the water heater main body are significantly different in shape. Therefore, a plurality of types of top protection members for protecting the top of the water heater are prepared in the packaging material according to each exhaust type. If dedicated top protection members were prepared for each exhaust type in this way, the types of packaging materials would increase accordingly, resulting in additional production and management costs.

The present invention has been made in view of the above circumstances, and it is possible to use a single type of member even when the exhaust types of the hot water heater are different depending on whether the exhaust section of the water heater projects forwardly or backwardly. The purpose is to provide packaging materials for water heaters.

The packaging material for a water heater according to the present invention includes:
A packaging material for a water heater compatible with an exhaust type in which an exhaust part protrudes from the front or back of a water heater body having a substantially rectangular parallelepiped shape,
Exterior members surrounding the left and right sides and front and back of the water heater;
a lower surface protection member that protects the lower surface of the water heater;
A top protection member that protects the top of the water heater;
A spacer member that protrudes to either the front or the rear of the top protection member and comes into contact with the inner surface of the exterior member to prevent the exhaust section that projects forward or backward of the water heater from coming into contact with the exterior member. Prepare,
The top protection member and the spacer member are provided with an engaging part and an engaged part that engage the two, and the spacer member can be combined into a form where the spacer member is attached to the front of the top protection member and a form where it is attached to the rear of the top protection member. shall be.

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

As described above, according to the configuration of the present invention, two types of exhaust can be handled with one type of top protection member and spacer member by simply replacing the spacer members back and forth. Therefore, there is no need to manufacture a dedicated top protection member for each exhaust type with a different protruding position of the exhaust part in the water heater, and it can be handled by combining one type of top protection member and spacer member. Furthermore, manufacturing costs and management costs for packaging materials can be reduced.

In the packaging material for the water heater,
The top protection member and the spacer member may be provided with a plurality of engaging portions and engaged portions that engage the two.
Thereby, the top protection member and the spacer member can be more firmly engaged, and the exhaust section of the water heater can be reliably protected.

In the packaging material for the water heater,
The top protection member and the spacer member may be configured to contact each other on at least two surfaces and engage the contact surfaces.
Thereby, the spacer member is attached to the front or rear of the top protection member in a state where movement of the top protection member in all directions, including the front-rear direction, the left-right direction, and the up-down direction, is prevented. Therefore, the set of the top protection member and the spacer member can reliably provide cushioning performance to the water heater without impairing it, and can reliably protect the exhaust section of the water heater.

Furthermore, in the packaging material for the water heater,
The top surface protection member is composed of left and right top surface protection members on the top surface of the water heater, and the left and right top surface protection members are configured such that one has a symmetrical shape with respect to the other,
The spacer member is composed of left and right spacer members attached to the left and right top protection members, respectively , and the left and right spacer members are configured such that one has a symmetrical shape with respect to the other, and each of the left and right spacer members is , has a horizontal piece part that contacts the top surface of the top protection member from above, and a box part that contacts the front or back side of the top protection member,
The engaging portion and the engaged portion between the top protection member and the spacer member may be provided at positions corresponding to the horizontal piece side and the box side of the spacer member, respectively.
Also in this case, the spacer member is attached to the front or rear of the top protection member in a state where movement of the top protection member in all directions including the front-rear direction, the left-right direction, and the up-down direction is prevented. Therefore, the set of the top protection member and the spacer member can reliably provide cushioning performance to the water heater without impairing it, and can reliably protect the exhaust section of the water heater.
