Description

[Detailed Description of the Invention] The present invention relates to an improvement of a solar water heater that is integrally equipped with a heat collector and a hot water storage tank, and has a water supply ball tap attached to the hot water storage tank.

In conventional solar water heaters of this type, in order to prevent the ball tap from vibrating and being damaged during transportation, the ball tap must be removed from the hot water tank and packaged separately for transportation, making installation work on site cumbersome. At the same time, there was a drawback that the number of parts and time required for packaging increased, resulting in higher costs.

The present invention was designed to solve the above-mentioned drawbacks, and uses parts inside the hot water storage tank to allow the ball tap to be transported while attached to the hot water storage tank, making on-site construction easier and cheaper. The purpose is to configure.

The basic structure of the present invention is as described in the claims for utility model registration, and the arm of the ball tap is formed by a notched groove for arm holding provided on a wall fixed near the ball tap in the hot water storage tank, for example, on the wall of the water supply guide. This prevents unnecessary movement of the driving parts of the ball tap, such as the ball tap arm, the float connected to it, and the valve drive rod, due to vibrations during transportation of the solar water heater. Try to prevent that damage.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a solar water heater to which the present invention is applied, in which a heat collector 1 and a hot water storage tank 2 are integrally housed in an exterior box 3. The heat collector 1 is provided with a heat collecting plate 5 on which heat pipes 4 are attached, a heat insulating material 6 is laid below the heat collecting plate 5, and a sash 7 is placed above the heat collecting plate 5. A transparent glass plate 8 fixed to the open end of the outer box 3 is disposed. A heat radiation part 4a of a heat pipe 4 protruding from a heat collecting plate 5 is inserted into the hot water storage tank 2 in a watertight manner.
Further, a ball tap 10 is inserted into the upper part of the hot water storage tank 2 through a water supply port 9 provided on the side wall of the hot water storage tank, and a ball tap 10 is inserted below the ball tap 10.
A cylindrical water supply guide 11 is provided to guide makeup water from 0 to the bottom of the tank. Further, 12 is provided at the lower part of the side wall of the hot water tank on the opposite side from the ball tap 10,
A hot water outlet 14, to which a hot water sampling pipe 13 extending upwardly in the tank is attached, is an overflow pipe that penetrates the side wall of the hot water storage tank while maintaining a predetermined spatial distance slightly below the ball tap 10.

As shown in FIG. 2, the ball tap 10 is inserted into the hot water tank by opening the lid 15 at the top of the hot water tank 2, then inserting the threaded mounting portion 10h into the through hole in the side wall, and attaching the flange 10i to the rubber gasket 16. While pressing the inner wall of the hot water tank 2 through the attachment part 1
It is watertightly attached to the hot water tank 2 by screwing a nut 18 through a rubber packing 17 to the hot water storage tank 2. The overflow pipe 14 is similarly attached to the hot water tank 2 using its own flange 14a, threaded attachment portion 14b, rubber packings 19, 20, and nuts 21. Note that the water supply guide 11 is fixed together with the overflow pipe 14 by being fastened together.

The water supply guide 11 is made of resin, and as shown in FIG. 3, it has a recess 11a at the upper opening end that allows the arm 10a of the ball tap 10 to move up and down, and the opening is narrower than the outer diameter of the arm 10a. A cutout groove 11b is provided, and the inside of this groove is formed to have approximately the same dimensions as the outer diameter of the arm 10a. Then, by slightly moving the arm 10a in the direction of the arrow and pushing it into the opening of the notch groove 11b, the arm 10a is engaged and held in the notch groove 11b, and the valve is opened as shown in FIG. The valve body 10c of the valve body 10b is joined to the valve seat 10d. In addition, during transportation, as described above, the arm 10a is engaged and held in the notch groove 11b, and the connecting rod 10e that connects the arm 10a and the valve 10b is fixed with a fastening member such as the string 22, so that the valve can be secured. The body 10c and the valve seat 10d can be joined more tightly, resulting in greater safety.

According to this embodiment, city water is supplied to the hot water tank 2 by the ball tap 10 up to the full water level, and during the day, heat is collected by the heat collecting plate 5 in the heat collector 1. Since the solar heat is sent to the hot water storage tank 2 by the heat transfer action of the heat pipe 4, the stored water is heated and becomes hot water. Then, by opening the faucet of a hot water supply pipe (not shown) connected to the hot water outlet 12, the hot water in the upper part of the hot water storage tank is drawn from the hot water sampling pipe 13 and is provided for hot water tapping. As a result, when the water level in the hot water tank 2 falls, water supply from the ball tap 10 starts. The make-up water from the ball tap 10 is guided to the bottom of the tank by the water supply guide 11, and the difference in specific gravity pushes up the hot water in the tank, so the hot water in the tank is taken out without mixing with the make-up water. be able to.

When the solar water heater of this embodiment is transported, the arm 10a of the ball tap 10 can be engaged and held in the notched groove 11b provided in the water supply guide 11, so there is no need to remove the ball tap 10 from the hot water tank 2, and on-site construction work is required. It's easy and ball tap 10
There is no need for packaging for water supply guide 1.
Since the arm 10a can be fixed at 1, there is no need to add any parts and the structure is inexpensive. In addition, since the arm 10a is fixed, the driving parts of the ball tap 10, such as the ball 10f connected to this arm and the connecting rods 10e and 22 that function as levers for driving the valve 10b, can also be fixed at the same time, and only the valve 10b can be fixed. Compared to fixing the ball 10f, there is no wear on the driving part, and compared to fixing the ball 10f, the holding part can be smaller. Furthermore, 10 g of valve port of ball tap 10
The mounting part 10h of the ball tap 10 is loosely attached to the hot water tank 2 so that it can be adjusted on-site.
By fixing the arm 10a, rotation of the ball tap 10 during transportation is also prevented.

In the above-mentioned embodiment, the arm holding part of the ball tap 10 is formed into the cutout groove 11b that is integrally provided in the water supply guide 11, but in the case where the ball tap storage case is provided in the hot water tank, the arm holding part is provided in the ball tap storage case. However, the present invention has various modifications.

As described above, the present invention provides a solar water heater that is equipped with a heat collector and a hot water storage tank and has a ball tap installed in the hot water storage tank. A notched groove for holding the arm is provided, and the opening of this groove is narrower than the outer diameter of the arm, and the inside of the notched groove is formed to be approximately the same as the outer diameter of the arm. This can be fixed by pushing the arm in, which eliminates unnecessary damage to the ball tap arm and the ball tap drive parts connected to it, such as the ball and lever, which occur due to vibrations during transportation of the solar water heater. This provides a solar water heater with the effect of preventing movement and preventing damage to the drive part of the ball tap during transportation of the water heater. This makes it possible to transport the ball tap while it is still attached inside the tank by using the parts inside the tank, making on-site construction easier.
It is economical because there is no need to package the ball tap, and existing parts such as water supply guides can be used and can be constructed at low cost, which is industrially superior. Furthermore, since the arm of the ball tap is fixed, the holding portion can be made small, the entire ball tap can be efficiently fixed, and it can withstand vibrations during transportation.
