Abstract

PURPOSE:To make the fitting screws for a supporting section unnecessary by a method wherein a partition plate is fixed by a partition plate pressing projecting from a tank cover. CONSTITUTION:The partition pressings 11 are fitted in opposition to respective support sections 5a of the tank cover 10 made of synthetic resin which closes the upper part of the tank. Checks 15 from the end surface of the respective partitions 8a are formed on the partition plate pressing contacting section 14 between the supporting plates 5a and the partition pressings 11 whereby they are given a spring function. According to this method, the partitions 8a are installed by putting it on the supporting parts 5a and the tank cover is fitted while the partitions 8a are fixed between the supporting parts 5a by the partition plate pressings 8a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tank device for a hot water heater or the like having a tank containing hot water returned from a hot water circuit.

BACKGROUND ART Page 2 Conventionally, this type of hot water heater has a structure as shown in FIGS. 4 and 6. That is, the combustion gas combusted in the burner 1 passes through the heat exchanger 2 and is discharged outside the machine by the combustion fan 3. On the other hand, as for the flow of hot water, hot water enters from a hot water return pipe 4, passes through a tank 6 and a circulation pump 6, is heated by a heat exchanger 2, and is circulated through a hot water outgoing pipe 7 to a hot water circuit (not shown). .

Here, the tank 5 shown in FIG. 4 is as shown in FIGS. 5 and 6. That is, inside the tank 5, two partition plates 8 are provided at different levels so that the circulating hot water does not constantly come into contact with air. Reference numeral 6a denotes a columnar support part that is integrally provided with the synthetic resin tank 6 and along its side wall, and supports each of the dividing plates 8. Reference numeral 9 denotes a screw for attaching the dividing plate 8 onto the support portion 5a. 12 is an inlet of the tank 5, and 13 is an outlet of the tank 6.

Problems to be Solved by the Invention However, in such a structure, each partition plate 8 is located near the center in the depth direction of the tank 6, and the screws 5
There was a problem in that it was difficult to tighten and remove the screws 9 because they were tightened close to the surrounding wall of the tank 5.

Means for Solving the Problems The technical means of the present invention for solving the above problems are as follows:
The partition plate is fixed with a temporary partition holder that protrudes from a tank lid that seals the tank.

For production The effect of this technical means is as follows.

That is, in the present invention, by simply installing the partition plate inside the tank and putting on the tank lid, the partition plate can be fixed using the partition temporary press that protrudes from the tank.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. Note that parts that are the same as those in the conventional example described above are given the same numbers, detailed explanations are omitted, and different parts will be mainly explained. 1st
In the drawings and FIG. 3, reference numeral 10 denotes a synthetic resin tank lid that seals the upper part of the tank 6, and a partition temporary press 11 is attached to each supporting portion 6a in the tank S so as to face each other. on the other hand,
In each partition plate 8a, a partition temporary press contact portion 14 sandwiched between the support portion 5a and the partition temporary press 11 is formed by cutting a notch 16 from the end face, thereby imparting spring properties.

In the hot water heater configured as described above, after installing the partition plate 8 on the support part 6a in the tank S, the tank lid 1o
When the partition plate 6 is attached, the partition temporary retainer 11 fixes the partition plate 6 to the support portion 6a as shown in FIG. and,
As shown in FIG. 2, the contact portion 14 of the partition plate 8 with the partition temporary presser 11 is configured to exhibit spring properties, and a recess (not shown) is large enough to allow the contact portion 14 to escape into the upper end surface of the support portion 5a. By providing this, even if there is a variation in the length of the partition temporary press 11, this can be absorbed and an unreasonable load will not be applied to the partition temporary press 11, and the tank lid 10 can also be installed reliably.

Effects of the Invention As described above, according to the present invention, since the tank lid that seals the tank has a partition temporary presser that presses down the partition plate, the partition plate can be easily fixed.
