Title: Air-con Oil Multi Silinder
Inventor: LIM YANG TAEK
IPC: F25B43/00
Filed: 2000-02-25
Abstract: PURPOSE: A multi-functional oil cylinder for an air conditioner is provided to inject refrigerant oil conveniently when a worker repairs an air conditioner equipment, to distinguish the color of the refrigerant by checking the refrigerant flow with the naked eye and to remove oil by separating the oil from the refrigerant without discharging the refrigerant out of the air conditioner system if a large amount of oil is supplied or the color of the oil is bad. CONSTITUTION: A multi-functional oil cylinder consists of an outer cylinder and an inner cylinder. The outer cylinder has the transparent case with an oil level scale(4) for measuring the amount of refrigerant oil to be charged exactly. The inner cylinder has an orifice on a partition in the middle to inject refrigerant flowing through a service valve(9) of a low-pressure manifold gauge(10). When refrigerant of a high-pressure air conditioner system flows to the low pressure through the manifold gauge, the refrigerant is injected to the outer cylinder from the orifice of the inner cylinder. A large amount bubbles are generated if a large amount of refrigerant oil is injected. The amount of bubble is decided in proportion to the amount of refrigerant oil. Thereby, the amount of refrigerant oil is checked. A worker can check the abrasion of an air conditioner compressor through the color of the air conditioner system oil. If the oil color is not clear, the refrigerant oil is separated from the refrigerant by a vortex generated from the flowing refrigerant. A safety valve(7) connected to an oil injection port prevents an accident caused by a damaged vessel by removing the inner pressure when the high pressure is supplied by user's mistakes.

Abstract: PURPOSE: A scale for displaying variation in weight is provided to manage the weight of a user effectively by displaying the variation in weight immediately through numerical value per specific period or graphs, and to promote convenience in use of plural people by automatically discriminating a user to be measured even though plural people uses the same scale. CONSTITUTION: Each unit of a scale is powered on by a power supply(12) and a CPU(Central Processing Unit,8) is operated to convert analog value of weight into digital value in an ADC(Analog to Digital Converter,7) when a user steps on a weight sensor(6). The CPU displays a name or an ID(Identification) number of the user on a displayer(9) by selecting the proximate data of the user from a database of a memory(10) if the converted digital value is set regularly. If plural values of proximate data exist, plural names or ID numbers of plural individuals are displayed on the displayer. The plural names and ID numbers are checked by the user through a key(13) and recorded on each corresponding database. Date data is read out of a clock(11) and then recorded on the memory. The weight data of the selected date are displayed by numerical value or graphs on the display unit. When the user comes down from the scale, the CPU controls the power supply not to feed power any longer. If the user wants to check the weight changes without getting on the weight sensor, the user selects the own data mode with the key and checks the weight data of numerical value or graph type through the displayer.
