JPH10147397A - Rectangle-shaped cold and hot water tank reinforced with heat-insulating material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate a dead space to save a heat-insulating material, and obtain a heat-insulating performance at a certain level or higher by forming a tank into a rectangular shape and reinforcing the tank with the thickness of a heat-insulating layer. SOLUTION: A urethane foam for an heat-insulating material is poured into a space between an outer plate 1 fixed so as not to be swollen by a foaming pressure and a structural plywood 3 bonded to a tank 4, and the space is packed with the urethane foam. With the aid of an adhesive force of this urethane foam used for packing, the structural plywood 3 is brought into close contact with the outer plate 1. By constituting the tank 4 in such way, the internal pressure of the tank 4 is received by the structural plywood 3 and, as a result, tensile stress generated in the urethane foam 2 is accepted by the outer plate 1 integrated with the urethane foam 2. By this method, a heat-insultating performance and effectiveness to be produced by forming the tank into a rectangular shape can be obtained at the same time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended for storing hot and cold water by utilizing temporarily supplied electricity such as late-night power, and cooling / heating exhaust heat.

[0002]

2. Description of the Related Art A conventional tank has a round shape in order to have an internal pressure stress. For this reason, dead space is created in the corner portion. Furthermore, when it is laid down, it is difficult to form a separation layer between water and hot water, and there is a problem in usability.

[0003]

By making the tank square, the dead space can be eliminated and the heat insulating material in that part can be saved. Furthermore, since the reinforcement is performed by the thickness of the heat insulating layer, the heat insulating performance of a certain level or more can be specified.

[0004]

This configuration will now be described. (A) an outer plate 1 fixed so as not to expand by foaming pressure;
While the structural plywood 3 is attached to the tank 4, the urethane foam 2 as a heat insulating material is injected and filled. (B) The urethane foam 2 makes the structural plywood 3 and the outer panel 1 adhere to each other with adhesive force. (C) Adjust the thickness of the urethane foam 2 according to the length of the long side of the tank 4 in the plane.

[0005]

The present invention has the above-described structure. Therefore, when pressure is received from the inside of the tank, the structural plywood 3 receives the pressure, and a tensile force is generated outside the urethane foam 2. The outer plate 1 integrated with the urethane foam 2 bears the stress against the tensile force. The outer plate 1 increases as the thickness of the urethane foam 2 increases.
The tensile stress becomes effective. Also, urethane foam 2
It has a certain level of compressive and tensile strength over itself, so that it is possible to simultaneously obtain the heat insulation performance and the rectangular shape.

[0006]

Next, an embodiment of the present invention will be described. (A) Example of the tank in which urethane foam 2 was used in place of isocyanurate foam. (B) An embodiment of the tank in which the structural plywood 3 is used in place of a slate or a compressed plywood. (C) An embodiment of the tank in which a pipe is installed in the urethane foam 2 and used.

[0007]

According to the present invention, the concept that the hot water storage tank having a temperature of nearly 100 degrees must be round can be overridden. (B) By making the hot water storage tank square, the size of the equipment having the hot water storage tank can be reduced. (B) By making the hot water storage tank square, space can be used without waste. (C) By making the hot water storage tank square, it is possible to balance the arrangement position with other equipment.

Claims (1)

[Claims] 1. An injection-type urethane foam 2 is provided between an outer panel 1 and a structural plywood 3 attached to a square cold / hot water tank 4.
Fill. The urethane foam 2 transmits the expansion pressure of the rectangular cold / hot water tank 4 by the structural plywood 3, and converts the transmitted pressure to the outer panel 1 by the adhesive force of the urethane foam 2 to transmit to the outer panel 1. By square cold and hot water tank.
