  • Patent number: 7896308
    Abstract: A mounting structure for a heat accumulation tank is provided with an elastic member that wraps around a tank main body, and a heat accumulation tank mounting member which wraps around the outer peripheral surface of the elastic member and holds the tank main body by being tightened in the circumferential direction, and which attaches to a receiving member. The elastic member is a molded part. The length of the elastic member is shorter than length of the circumference of the outer peripheral surface of the tank main body. The heat accumulation tank mounting member includes a shift inhibiting portion which inhibits an upward shift of the tank main body. The outside diameter of the tank main body becomes increasingly wider in the upward direction.

  • Patent number: 6742480
    Abstract: In a heat storage tank, a discharge port of an introduction passage is covered by a cup-shaped collision member constructed by a shield portion and a guide cover. In addition, a mixture protection plate having plural through holes is disposed in a tank body between the collision member and an inner surface of the tank body. Therefore, a high-speed water stream, upwardly injected from the discharge port, collides with the shield portion, and turns its flow direction by an approximately right angle. Thereafter, the water stream is guided by the guide cover to a lower side of the mixture protection plate. Accordingly, it can prevent water stored in the tank body from being mixed even when the injection water stream has a high speed.

  • Patent number: 6718925
    Abstract: In a heat storage tank, an elbow pipe member defining a water introduction passage is formed by connecting an inlet-side cylinder portion and an outlet-side cylinder portion to have a corner portion. A step portion is disposed in the water introduction passage around a position where center lines of both the cylinder portions are crossed with each other. The step portion has a collision surface that is set to cross with a line parallel to the center line of the inlet-side cylinder portion, so that water introduced from the inlet-side cylinder portion collides with the collision surface of the step portion.

  • Patent number: 6557502
    Abstract: In a water discharge mode (heat storage mode) for discharging low-temperature cooling water from a heat storage tank to a side of a heater core that heats air using cooling water from an engine as a heating source, a cooling water amount discharged from the heat storage tank is made smaller as a necessary heating capacity for heating air becomes larger. For example, as an amount of air flowing through the heater core becomes larger, the cooling water amount discharged from the heat storage tank becomes smaller. Further, as the temperature of the cooling water flowing into the heater core becomes higher, the cooling water amount discharged from the heat storage tank is increased.
