Abstract: A vehicular cleaner system (1) for cleaning a to-be-cleaned object (100), wherein: the vehicular cleaner system (1) is provided with a tank (11) that accommodates a cleaning liquid, a pump (12) that pressure-feeds the cleaning liquid inside the tank (11), a high-pressure-air generation unit (2) that generates high-pressure air, a first ejection port that sprays the cleaning liquid toward a cleaning surface of the to-be-cleaned object (100), a second ejection port that sprays the high-pressure air toward the cleaning surface, and a controller (4) and vehicle ECU (40) that control the spraying of the cleaning liquid and the spraying of the high-pressure air; and the controller (4) and the vehicle ECU (40) perform control so as to initiate the spraying of the high-pressure air from the second ejection port after spraying of the cleaning liquid from the first ejection port has been initiated.

Abstract: A safety device for an oil burner is disclosed which is capable of carrying out the detection of flame by means of a DC flame current obtained due to the rectification of flame to detect the abnormal combustion in the oil burner. The safety device includes a first flame electrode surrounded by flame of normal combustion in the oil burner and a second flame electrode arranged away from the flame and connected to an AC voltage source in a manner to be in parallel with the first flame electrode, so that the second flame electrodes cooperates with the first flame electrode to detect a failure in the flowing of a flame current through the first flame electrode or a decrease in a flame current flowing through the first flame electrode, to thereby determine any abnormal combustion in the oil burner.

Abstract: A construction for preventing oil leakage in an oil burner is disclosed which is capable of effectively preventing oil leakage from an oil burner, particularly, a means for supporting a cartridge-type oil tank on an auxiliary tank when the burner falls down in any direction. The construction includes an oil reservoir mounted through the oil tank supporting means in the auxiliary tank and provided with a through-hole at the side portion thereof facing a combustion mechanism of the burner only through the oil tank is communicated with the auxiliary tank. The auxiliary tank has a volume determined to allow an oil level in the auxiliary tank to be constantly lower than the through-hole of the oil reservoir even when the oil burner falls down in any direction to prevent oil leakage from the oil tank supporting means.

Abstract: A red-hot type oil burner capable of effectively accomplishing uniform vaporization of a fuel oil during the normal combustion operation. A heat transfer means is provided between a combustion chamber and a vaporization chamber to transmit a part of combustion heat to the vaporization chamber. The oil burner may be provided in a mixing chamber with a diffusion plate having a cutout to allow the ignition to be rapidly and safely effected. The oil burner may be also provided with a device for preventing the generation of a bad odor. There is also disclosed a red-hot type oil burner capable of surely confirming the completion of the igniting and fire extinguishing operations.

Abstract: An oil burner of the type of pumping up a fuel oil is disclosed which has a first oil level setting means of an airtight type having an overflow pipe means constantly immersed at the lower end thereof in a fuel oil to be pumped up to the first oil level setting means and has a second oil level setting means disposed below the first oil level setting means and directly connected to a fuel oil supply tank. A fuel oil supplied from the second oil level setting means is drawn up to the first oil level setting means by a pumping-up means and subsequently supplied through a supply pipe to a combustion means. The level of a fuel oil in the first oil level setting means is kept constant at a position above the outlet end of the supply pipe. The overflow pipe means may be movable in the vertical direction so as to vary only the supply rate of a fuel oil.
