A vehicle fluid exchange machine is disclosed that allows the technician to control the flow into the vehicle or stand-alone cooling or hydraulic system either manually or automatically based on a safe working pressure for the vehicle. If the vehicle's cooling system can handle a higher pressure for example, the technician may adjust the machine's flow to a flow rate consistent with the higher pressure rating while monitoring the pressure across the system. The default setting for the air injection process is automatic, but can also be switched to manual by the technician.

A water purifier includes a body part generating purified water, hot water, and sterilization water. The body part includes: a filter purifying water, a hot water module that defines a heating flow path through which the purified water passing through the filter passes and that heats the purified water passing through the heating flow path into hot water, an intermediate flow path connecting the filter to the hot water module, a sterilization water flow path having a first side branched from the intermediate flow path and a second side connected to a water outlet, a sterilization water module installed in the sterilization water flow path and electrolyzing water passing through the sterilization water flow path into sterilization water, a hot water flow path guiding the hot water passing through the hot water module toward a water discharge nozzle, and a controller controlling the hot water and sterilization modules.

A water ejecting apparatus includes a case and a water ejection unit connected to one side of the case. The water ejection unit includes a fixed cover, a lifting cover, a lifting motor, a water ejection nozzle, a touch bar, a detection sensor, and a controller. The fixed cover is connected to the case. The lifting cover is movably received in the fixed cover and coupled to the lifting motor. The water ejection nozzle is installed at a lower end of the lifting cover and configured to eject water. The touch bar is at least partially received in the lifting cover and moves when in contact with a container placed below the water ejection nozzle. The detection sensor detects movement of the touch bar. The controller changes operation of the lifting motor when the detection sensor detects movement of the touch bar.

A water ejecting apparatus includes a case and a water ejection unit connected to the case. The water ejection unit includes a fixed cover connected to the case, having atop dead point and a bottom dead point, and including a lifting gear provided between the top dead point and the bottom dead point, a lifting cover movably coupled to the fixed cover, a lifting motor coupled to the lifting cover and a gear module interworking with the lifting motor and the lifting gear, a water ejection nozzle for ejecting water, a signal detecting unit that detects a frequency generation (FG) signal generated by the lifting motor during an operation of the lifting motor, and a controller configured to control the operation of the lifting motor upon determining that the lifting cover reaches the top dead point or the bottom dead point based on the FG signal.

A stirrer includes a stirring shaft; a plurality of mixing wings extending from the lower end of the stirring shaft and spaced from each other around the stirring shaft; and a conical hub connecting the lower ends of the mixing wings.

This disclosure relates to a sanitary fitting for dispensing prepared liquids, for example, for beverages. A disclosed system includes a first control element for setting a quantity of the prepared liquid to be dispensed and an actuating element for providing the quantity of prepared liquid set by means of the first control element, wherein at least one second control element is configured to select a type of preparation, for example, from at least two different types of preparation, of non-prepared liquid, wherein the first and the at least one second control element are actuatable independently of one another.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.

A water purifier includes a raw water flow path into which raw water is introduced, a clean water flow path connected to the raw water flow path and having a water discharge nozzle disposed at an end, a filter device disposed in the clean water flow path, and to which a filter is installable to filter the raw water, a drain flow path branched off from the clean water flow path between the filter and the water discharge nozzle and connected to a drain port to drain water in the clean water flow path to outside, a drain valve configured to open or close the drain flow path, and a controller configured to determine a remaining life of the filter on a point in time at which the filter has been replaced and control the drain valve to perform a cleaning operation based on the remaining life of the filter.

The present invention relates to a multi-purpose hydration station for dispensing different kinds of beverages, soft ice, ice, hot water and non-heated water. More specifically, the multi-purpose hydration station features a hot water dispenser unit, a non-heated water dispenser unit, a beverage dispenser unit, a soft ice dispenser unit and an ice maker for dispensing the user's requested item and eliminates the need to use separate dispensing machines to dispense different kinds of beverages or items. Additionally, the hydration station features a refrigeration and a non-refrigeration storage area to allow the users to store their items as per their requirements. The hydration station offers a convenient solution for setting up a hydration station that saves space, energy and expenses of the user.

A bottle filling station may include a liquid dispenser configured to dispense liquid. A pan may be configured to collect at least a portion of the dispensed liquid. A sensor may detect a presence of a liquid container. A controller may control the liquid dispenser to dispense liquid when the liquid container is approximately near the sensor.
