Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a solar heat collector used in a solar heat utilization system for houses and the like.

BACKGROUND OF THE INVENTION 2. Related Art and Problems There are known solar heat collectors that include a sealed exterior box in which a heat collector is housed.

By the way, as mentioned above, since the outer box is sealed, dew condensation is likely to occur inside the outer box, and in order to prevent this, vents are provided in the peripheral wall of the outer box to communicate the inside and outside of the outer box. However, to prevent rainwater from entering through the vents, a cover was installed.

The purpose of this invention is to provide a solar heat collector that can prevent rainwater from entering through the vents without requiring a special cover or the like to be attached to the vents.

Means for Solving the Problems In the solar heat collector according to this invention, the peripheral wall of the outer box is composed of four wall members, and the peripheral wall of the outer box is attached to the outer surface of the adjacent end of two wall members that are perpendicular to each other. In a solar heat collector in which a connecting member having an L-shaped horizontal cross section is applied and fixed there, a vertical groove is formed in the inner corner of the connecting member, and a vent is provided to communicate the vertical groove with the inside of the outer box. It is characterized in that it is provided at at least one end of the same two wall members.

Embodiment An embodiment of this invention will be described below with reference to the drawings.

In the following description, the front and rear refer to the left side of FIG. 1 as a reference, the opposite side to the front and the rear, and the left and right sides refer to the rear.

The solar heat collector includes a rectangular sealed exterior box 11 that is long in the front-rear direction when viewed from above, and a heat collector 1 is attached to this.
2 is accommodated. Since the heat collector 12 is well-known, its explanation will be kept brief below, but it includes parallel water pipes 13 extending in the front-rear direction, a heat collecting plate 14 fixed across the water pipes 13, It consists of front and rear headers 15 and 16 provided at both ends of the water pipe 13, respectively.

The peripheral wall of the outer box 11 is composed of a front wall member 21, a rear wall member 22, and left and right side wall members 23, 24. A connecting member 25 having an L-shaped horizontal cross section is applied to the outer surface of the end of each of the adjacent wall members 21 to 24 so as to straddle them.

The wall members 21 to 24 are all made of extruded aluminum and have substantially the same cross-sectional shape. As a representative of the wall members 21 to 24, the front wall member 21 shown in FIG. 3 will be described.
An upper horizontal wall 32 that protrudes inward from a point slightly below the upper end, a lower horizontal wall 33 that protrudes inward from a lower end of the vertical wall 31, and an intermediate portion that protrudes inward from a point slightly above the lower horizontal wall 33. A horizontal wall 34 is provided. A receiving member 35 having a horizontally tilted T-shaped cross section is placed on the upper horizontal wall 32, and the front edge of the lower transparent plate 36 is sandwiched between the horizontal part of the receiving member 35 and the upper horizontal wall 32 via a gasket 37. The front edge of the transparent plate 38 is placed on the horizontal part via the gasket 39, and the horizontal part of the holding member 40, which has an inverted L-shaped cross section, presses the front edge of the latter from above. It is screwed to the outer surface of the upper end of the vertical wall 31. Further, a header support member 41 is screwed to the middle of the height of the inner surface of the vertical wall 31. Furthermore, the front edge of a bottom plate 42 made of a heat insulating panel is sandwiched between the intermediate horizontal wall 34 and the lower horizontal wall 33, and a glass wool heat insulating material 43 is placed on top of the bottom plate 42. Is receiving. Four first to fourth ventilation holes 51 to 54 are sequentially formed from above at opposing ends of two adjacent wall members 21 to 24. The first vent 51 is connected to each wall member 51 to 5.
It is located at a distance slightly above the upper horizontal wall 32 of 4 and is covered by a presser member 40. The second ventilation hole 52 is located at the third side of the horizontal wall 32.
The ventilation hole 53 is a fourth ventilation hole 54 in the intermediate horizontal wall 34.
are located immediately above the lower horizontal wall 33, and both are covered by the connecting member 25. Furthermore, as a representative of the respective ventilation holes 51 to 54, the second ventilation hole 52 shown in FIG. 2 will be explained. Notch 5
5, 56 are formed, and two notches 55, 56 are formed.
The vent holes 52 are combined into one vent hole 52.

The connecting member 25 is made of extruded aluminum and has a length that can cover the portion of the outer end of each of the wall members 21 to 24 that is not covered by the presser member 40. As shown in FIG. 2, an L-shaped central longitudinal groove 61 is formed at the inner corner of the connecting member 25, spanning two right-angled surfaces of the same inner surface, and side longitudinal grooves 62 are formed on both sides thereof. each formed. The second to fourth vents 52 to 54 communicate with the central longitudinal groove 61, respectively, except for the first vent 51. A sealing material 63 is filled in each of the side longitudinal grooves 62, and the tapping screw 64 passes through the sealing material 63 and is screwed into the wall members 21 and 24, so that the connecting member 25 is connected to the wall member. 21 and 24.

Effects of the invention According to this invention, a vertical groove is formed at the inner corner of the connecting member, and a vent that communicates the inside of the outer box with the vertical groove is provided at the end of the wall member. Because it will be covered by the connecting member,
There is no risk of rainwater entering through the vents. Moreover, since the connecting member also serves as a cover for the conventional device mentioned at the beginning, there is no need to prepare a special cover.
