Description

[Detailed description of the invention] The present invention is a heat exchanger in which a burner container with a built-in lower burner can be easily installed or removed without flames spewing out from the installation position. This invention relates to an improvement of a burner attachment/detachment device.

Conventionally, in heat exchangers consisting of boilers, water heaters, etc. that use the combustion heating of a burner to perform heat exchange, the burner is generally fixed directly to the heat exchanger's fire port or is pivoted to the heat exchanger. The heat exchanger is either placed on a closed door, or placed under a heat exchanger via a complicated mounting means, so that the combustion flame of the burner performs the heat exchange action.

Therefore, according to the conventional mounting method for this type of burner, it is necessary to attach a mounting member to the burner itself, which not only makes processing work difficult, but also makes it difficult to remove the burner from the fire spout for replacement or repair. Even if necessary, it was difficult to easily remove only the burner, which was very inconvenient.

In view of the foregoing, the present invention provides a heat exchanger and a burner separately, and the burner is housed in a burner container to greatly simplify the installation of the burner, and the burner container is attached to the heat exchanger mounting board. The burner can be inserted and removed freely, so that the burner can be easily installed or removed from the heat exchanger by simply inserting and removing the burner container, making it easier to replace and repair the burner. An attempt is made to provide a burner attaching/detaching device for a heat exchanger which prevents flames from accidentally blowing out into the surrounding area from the mounting position of the burner container by attaching flame blowout prevention strips to the front and rear upper surfaces of the rim, DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the apparatus of the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a heat exchanger that effectively exchanges heat from the combustion heat of a burner such as a boiler or a water heater, and a rectangular flat mounting board 2 is integrally formed at the bottom of the heat exchanger 1. It may be attached as a separate item.

Note that the mounting board 2 may have a semicircular shape instead of a rectangular shape.

Then, the left and right sides of the mounting board 2 are respectively bent inward in a U-shape to form retaining guide rails 3, 3.

Reference numeral 4 denotes a burner of a suitable type equipped with a combustion tube 5 facing upward, and the burner 4 is housed in a burner container 6 with an open top and an intake passage 7 to the burner 4 opened at the bottom. .

The projecting edge 8 of the burner container 6 is formed in a similar shape to the mounting board 2, and the projecting edge 8 is connected to the two engagement guide rails 3, 3.
It can be inserted and removed freely.

Note that when the overhanging edge 8 is fitted into the locking guide rail 3.3, it is extremely effective to interpose backings 9, 9 between the overhanging edge 8 and the locking guide rails 3,3.

In addition, a pair of flame-spout prevention strips 10, 10 are provided on the upper surface of the overhanging edge 8 at the front and rear positions that do not fit into the engagement guide rails 3, 3 in order to prevent combustion flames from spewing out to the outside. .

Reference numeral 11 denotes a presser rod whose one end is pivotally connected to the insertion side end of the mounting board 2, and the free end side of the presser rod 11 is attached to an appropriate mounting piece 12 provided on the mounting board 2 at a position opposite to the pivoting side. The burner container 6, which is tightly secured and fitted through the fasteners 13, is attached to the lower part of the heat exchanger 1.

Next, the operation of the present invention will be explained.

Now, if you want to easily attach the burner 4 to the lower part of the heat exchanger 1 using this device and perform heat exchange work, first store the burner 4 in the burner container 6, and then store the burner 4 in the burner container 6. By fitting the protruding edges 8 of 6 along the two engagement guide rails 3, 3 provided on the left and right sides of the mounting board 2 and tightening them with the presser rods 11, the burner container 6 can be easily and reliably heated. The flame is attached to the lower part of the exchanger 1, and the flame is connected to the front and rear flame prevention strips 10, 10 and the left and right retaining guide rails 3, so that a good heat exchange operation can be achieved by the combustion heating of the burner 4. 3 prevents it from spewing out from the mounting position to the surrounding area.

Therefore, during the heat exchange work as described above, if you want to remove the burner 4 from the heat exchanger 1 in order to replace it with another one or repair it due to a malfunction or the like, the presser rod 11 should be removed. After removing the tensioning tool 13 and vibrating it,
By pulling out the burner container 6 along the retaining guide rails 3, 3, the burner container 6 can be quickly and easily removed from the heat exchanger 1, making it easy to replace or repair the burner. Can be done.

In short, the present invention provides a mounting board 2 at the bottom of the heat exchanger 1, and retaining guide rails 3 on both left and right sides of the mounting board 2.
3, a burner 4 is built into the engagement guide rails 3, 3, and a projecting edge 8 of a burner container 6, which has a flame blowout prevention strip 10, 10 attached to the upper surface of the front and back positions, can be freely inserted and removed. Since it was inserted into the presser rod 11 and attached with the presser rod 11,
The burner container 6 can be easily and quickly attached to the lower part of the heat exchanger 1 by simply vibrating the presser rod 11 and inserting the burner container 6, without the need to attach a mounting member to the burner 4 itself. If possible, if you pull out the burner container 6 along the retaining guide rails 3, 3, you can easily remove the burner container 6.
can be removed from the lower part of the heat exchanger 1, and an accident of flame spewing out from the mounting position can be prevented.

Therefore, if the device of the present invention is used, the operation of attaching and detaching the burner 4 is very easy, so that the burner 4 can be easily replaced or repaired while saving labor.
