Patent number: 6742480Abstract: 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.Type: GrantFiled: June 19, 2002Date of Patent: June 1, 2004Assignees: Nippon Soken, Inc., Denso CorporationInventors: Sadahisa Onimaru, Toshio Morikawa, Koichi Ban, Takashi Toyoshima

Patent number: 6622787Abstract: A defroster/face cool air passage for introducing cooled air from an evaporator to a defroster opening portion and a face opening portion by bypassing a heater core, and a foot cool air passage for introducing cooled air from the evaporator to a foot opening portion by bypassing a heater core, are formed independently from each other. The foot cool air passage is located at sides of the heater core in a vehicle right-and-left direction. The cooled air from the foot cool air passage is mixed with warmed air having passed through the heater core at an inlet of the foot opening portion. Accordingly, pressure loss at a foot mode in an air conditioning unit with a central installation layout is reduced, and a mounting performance on a central portion of a vehicle instrument panel is improved.Type: GrantFiled: May 17, 1999Date of Patent: September 23, 2003Assignee: Denso CorporationInventors: Takashi Toyoshima, Kazushi Shikata, Yukio Ueno, Nobuyuki Doi

Patent number: 6477990Abstract: In a heat storage tank, first and second valve bodies are disposed to open and close first and second valve ports, respectively. A density of the first valve body is made larger than that of cooling water, and a density of the second valve body is made smaller than that of cooling water. When the dynamic pressure due to cooling water is applied to the first and second valve bodies, the first and second valve ports are opened by the first and second valve bodies. On the other hand, when the dynamic pressure is not applied to the first and second valve bodies, the first valve body closes the first valve port by the weight of the first valve body, and the second valve body closes the second valve port by the buoyancy.Type: GrantFiled: October 4, 2001Date of Patent: November 12, 2002Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Takashi Toyoshima, Toshio Morikawa, Ikuo Ochi, Koichi Ban, Sadahisa Onimaru
