Description

[Detailed Description of the Invention] Industrial Field of Application The present invention includes: a heat collecting section having a solar light transmitting member on its upper surface; a heat storage tank disposed above the heat collecting section in an inclined state; The heat storage tank is provided with an opening for attaching a ball tap and a lid that closes this opening to prevent evaporated water in the heat storage tank from being released from the gap between the heat storage tank and the lid. This relates to a solar water heater.

Conventional Structure and its Problems A conventional solar water heater of this type has a structure as shown in FIGS. 1 and 2. That is, in FIGS. 1 and 2, 1 is a heat storage tank, 2 is a heat insulating material disposed outside the heat storage tank 1, and 3 is a heat pipe, and this heat pipe 3 is connected to the evaporation section 3.
a is disposed in the heat collecting part 4, and a condensing part 3b is disposed in the heat storage tank 1, and the condensing part 3b exchanges heat with the water in the heat storage tank 1 to make it hot water. .
Reference numeral 5 denotes a heat insulating material disposed below the heat collecting section 4, 6 an exterior body, and a sunlight transmitting body 7 disposed above the heat collecting section 4 on the upper surface of the exterior body 6. There is. Reference numeral 8 denotes an opening provided on the upper surface of the heat storage tank 1 for attaching a ball tap, and a lid 9 made of synthetic resin is installed on this opening 8 to close the opening 8. Reference numeral 10 denotes a lid provided on the exterior body 6 so as to correspond to the lid 9. Further, the heat storage tank 1 is disposed above the heat collecting section 4 in the inclined state.

However, in the above conventional configuration, the heat storage tank 1
The evaporated water that evaporated inside the lid 9 adheres to the inner surface of the lid 9, and when this evaporated water cools, it becomes water droplets and flows along the slope as shown in FIG. It enters the gap with the heat storage tank 1 by capillary action and flows out of the heat storage tank 1. in this case,
Since the lid 9 is made of synthetic resin, when the temperature rises, the lid 9 will warp more, and as a result, the gap between the lid 9 and the heat storage tank 1 will become larger, and the water droplets will be further removed from the heat storage tank 1. It becomes easy to come out. The water droplets flowing out of the heat storage tank 1 may corrode the iron parts housed in the exterior body 6 or, depending on the outside temperature, cause condensation on the sunlight transmitting body 7 of the heat collecting part 4. There were times when I did something like that. When the sunlight transmitting body 7 condenses, there is a problem that the sunlight transmittance is significantly lowered and the heat collection performance is lowered.

Purpose of the invention In view of the above-mentioned conventional problems, the present invention provides a solar water heater having a structure that prevents water droplets from evaporating water inside the heat storage tank from flowing out of the heat storage tank through the gap between the lid and the heat storage tank. The purpose is to provide

Structure of the invention In order to achieve the above object, the present invention is provided with a protruding rib for recovering evaporated water in the heat storage tank on the lower surface of the lid that closes the opening for attaching the ball tap provided in the heat storage tank. According to this configuration, when the water droplets from the evaporated water in the heat storage tank adhering to the bottom surface of the lid flow along the slope, they are caught by the protruding ribs and collected in the hot water section in the heat storage tank, unlike the conventional method. Since it does not flow out of the heat storage tank, it is possible to solve the problem of corrosion of iron parts or deterioration of heat collection efficiency due to dew condensation on the sunlight transmitting body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In FIG. 3, the same parts as in FIGS. 1 and 2 shown in the conventional example are given the same numbers, and only the points different from the conventional example will be explained. That is, in one embodiment of the present invention,
A protruding rib 11 for recovering evaporated water in the heat storage tank 1 is integrally formed on the lower surface of a lid 9 made of synthetic resin that closes an opening 8 for attaching a ball tap over the entire circumference. By having such a configuration,
When water droplets due to evaporated water in the heat storage tank 1 adhering to the inner surface of the lid 9 flow along the slope, the protruding ribs 11
The water is received by the heat storage tank 1, and is collected by the hot water section in the heat storage tank 1 through the protruding ribs 11. Furthermore, since the protruding ribs 11 are formed on the inner surface of the lid 9 over the entire circumference, thermal deformation of the lid 9 is less likely to occur, and therefore the adhesion between the heat storage tank 1 and the lid 9 is improved.

Effects of the invention As described above, according to the invention, the opening for installing a ball tap provided in the heat storage tank is closed, and a protrusion for collecting evaporated water is provided on the lower surface of the lid, which is arranged in an inclined state, and is spaced apart from the periphery of the opening. Because the ribs are provided, when water droplets from the evaporated water in the heat storage tank adhere to the inner surface of the lid flow along the slope, they are caught by the protruding ribs and collected into the hot water part of the heat storage tank. As a result, it does not flow out of the heat storage tank like in the past, so it does not corrode iron parts,
Alternatively, it is possible to solve the problem that heat collection efficiency is reduced due to dew condensation on the sunlight transmitting body.

Furthermore, since the protruding ribs are spaced apart from the periphery of the opening, water droplets caused by evaporated water will not be transmitted to the gap between the lid and the opening, thereby reliably suppressing the capillary phenomenon.
