Description

  TECHNICAL FIELD The present invention relates to a water heater mounting structure suitable for, for example, a case where a water heater is installed in a pipe shaft (also referred to as a pipe space) of an apartment house, and a bracket for a water heater used therefor.

When installing a water heater in the pipe shaft of an apartment house, a means as shown to Fig.5 (a) is often employ | adopted (for example, patent document 1).
In the figure, a bracket Ba for a hot water heater is attached to a fixed frame 1 installed in a pipe shaft. The bracket Ba has a frame-shaped portion 4 that surrounds the upper, lower, left, and right sides of the water heater 3 </ b> A. The attachment piece 59 protruding upward from the front portion of the upper plate portion 4 a of the portion 4 is screwed using a screw body 90. The water heater 3 </ b> A is attached to the bracket Ba using a plurality of screw bodies 91 in a state of being arranged inside the frame-like portion 4. The fixed frame 1 is provided with a rotary door 2 that can cover the front surface of the water heater 3A. The door 2 has an opening for exposing the exhaust tube 30 of the water heater 3A to the outside. 21 is formed.
According to such a configuration, since the upper, lower, left, and right peripheries of the water heater 3A are surrounded by the frame-like portion 4 of the bracket Ba, hot water is supplied by the bracket Ba while reducing the substantial occupied space of the bracket Ba. It is possible to fix the container 3A stably. It is also possible to improve the appearance from the front of the water heater 3A.

  However, the prior art has room for improvement as described below.

That is, the water heater 3A may be replaced with a new water heater 3B as shown in FIG. 5B due to a failure or other reason. Here, the new water heater 3B is not the same size as the previous water heater 3A but may be larger than the previous water heater 3A. In this case, the dimension L1 from the upper surface portion of the new water heater 3B to the exhaust tube 30a is often larger than the dimension L2 from the upper surface portion of the previous water heater 3A to the exhaust tube 30. Therefore, the height of the exhaust tube 30a of the water heater 3B (the height of the base of the exhaust tube 30a) is determined by simply using the bracket Ba having a size corresponding to the water heater 3B. Therefore, it is difficult to expose the exhaust pipe 30a to the outside through the opening 21 as it is.
As means for eliminating this, there is means for using the exhaust adapter 30b bent so as to have a height difference between the front and rear ends. However, the use of such means is disadvantageous in terms of cost, as well as the water heater 3B. There is also a problem that exhaust resistance increases. Unlike this, it may be possible to replace the door 2, but adopting such means is not only more costly, but the replacement of the door 2 is not easy and is not practical. .

The above-described example is an example in which when the hot water heater is replaced, the exhaust pipe of the water heater and the opening of the door are displaced from each other. However, such a malfunction is caused by the installation height of the new water heater. It is possible to solve this problem by increasing the value. On the other hand, conventionally, it is higher than the lower surface of the front portion 40e of the upper plate portion 4a (upper edge portion of the front opening formed inside the frame portion 4) of the frame portion 4 of the bracket Ba. It is set as the structure which cannot arrange | position the water heater 3B in a position. When attaching the water heater 3B to the fixed frame 1 or other desired attachment object, there are cases where it is desired to arrange the entire water heater 3B at as high a position as possible. It is not something that can be answered.

For this reason, the mounting height of the water heater 3 can be increased. As a result, even if the dimension La from the upper surface of the water heater 3 to the exhaust cylinder 30 is relatively large, the exhaust cylinder 30 is not lowered to a height lower than the opening 21 and these heights coincide with each other. By doing so, the exhaust tube 30 can be appropriately exposed from the opening 21 to the front side of the door 2. It is not necessary to use the exhaust adapter 30b shown in FIG. Therefore, it is advantageous in terms of cost, and it is possible to prevent an increase in exhaust resistance in the water heater 3 that occurs when the exhaust adapter 30b is used.

  As shown in FIG. 4, the front portion 40 of the upper plate portion 4a can be detached from other portions of the upper plate portion 4a. In this case, the connection of the front portion 40 to the receiving piece portion 12 is also released, but the bracket B is separately screwed to the receiving piece portion 13 of the fixed frame 1 as described with reference to FIG. Therefore, the mounting state of the bracket B with respect to the fixed frame 1 is not unreasonably released due to the removal of the front portion 40. When the front portion 40 is removed as described above, the front cover 33 of the water heater 3 can be removed to the front side of the bracket B. In a state where the front portion 40 is assembled to the upper plate portion 4a, when the front cover 33 is to be removed to the front side of the bracket B, the front cover 33 interferes with the front portion 40, and the front cover 33 is removed. Although it is difficult to remove, such a thing can be eliminated by removing the front portion 40. When the front cover 33 is removed, maintenance of the water heater 3 can be performed from the front side while the main body 32 of the water heater 3 is attached to the bracket B, which is convenient. Further, if the front portion 40 is detachable as in the present embodiment, the assembly work of the water heater 3 to the bracket B and the whole removal work of the water heater 3 can be performed more easily and appropriately. Become.
