  • Publication number: 20240068460
    Abstract: A variable displacement swash plate type compressor control method and a variable displacement swash plate type compressor controlled thereby may include a first determination step of determining whether liquid refrigerant exists within the variable displacement swash plate type compressor; a first operation step of applying power to the field coil assembly and of not applying current to the electronic control valve, when it is determined in the first determination step S1 that the liquid refrigerant exists; a second determination step of comparing an elapsed period of time of operating in the first operation step with a predetermined reference time; and a second operation step of maintaining the power applied in the first operation step to the field coil assembly and applying current to the electronic control valve when the elapsed period of time is greater than or equal to the reference time.

  • Patent number: 10292549
    Abstract: A flush toilet capable of correcting a defecation posture, in which a seat disposed on a toilet main body for a user to sit is inclined on the top thereof such that the front where the user's thighs are placed is higher than the rear where the user's hips are placed. Accordingly, smooth defecation is allowed by preventing bending between the intestine and the anus in the body by correcting the posture of a user into a squatting posture such that an angle between the upper body and the thighs of the user is maintained between 35˜50° as if the user were using a squat toilet. Therefore, defecation time is reduced and the user's legs are prevented from becoming numb, thereby improving satisfaction with defecation. Further, intestinal movement is activated during defecation, so smooth defecation is possible, and constipation, hemorrhoids, irritable bowel syndrome, cancers, and other colorectal diseases are prevented.
