Provided is a fire extinguisher which reduces a risk of a discharge accident caused when a stopper is unintentionally separated at a normal time and from which a handle is easily pulled out when fire occurs. According to the fire extinguisher, a force pressing an upper handle is not transmitted to a valve stem as a gap between the upper handle and a plug is maintained by a gap support part when the stopper is installed on the handle, and the force pressing an upper handle is transmitted to the valve stem through a valve pressing part as the gap support part horizontally moves by an elastic member so as not to overlap the plug when the stopper is separated from the handle.

Fire extinguisher with easy management and usage

An electric cooker is configured to cook food in a pressurized state and a non-pressurized state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body having an inner pot configured to accommodate food and a heating unit; a lid coupled to an upper portion of the main body and opened/closed by an opening/closing unit; and a pressure switching selection unit arranged to pass through the lid and configured to switch or maintain opened/closed states to discharge internal steam from the inner pot by interworking with the opening/closing unit.

Provided are a branch tee for sprinkler pipes, which is capable of selectively sprinkling fire extinguishing water only on a fire occurrence area and preventing the skipping effect although there are many obstacles to sprinkling water or a distance between sprinkler heads is narrow, and a sprinkler pipe system including the branch tee. The branch tee for sprinkler pipes includes a branch tee body () having a cylindrical shape, a first outlet () disposed on one end of the branch tee body () and connected to a pipe of a closed sprinkler head, an inlet () disposed on the branch tee body () and connected to a water supply pipe, a second outlet () disposed on the branch tee body () and connected to a pipe of an open sprinkler head, a piston valve disposed in the branch tee body () and simultaneously controlling opening and closing of each of the first outlet () and the second outlet () while moving in a longitudinal direction of the branch tee body () due to a fluid pressure difference in the branch tee body () when fire occurs, and an inner wall groove () defined in an inner wall of the branch tee body () between the piston valve and the first outlet ().

Branch tee for sprinkler pipes controlling water stream automatically and sprinkler pipe system having the same

Provided is an automatic fire extinguisher providing a simplified operation method for easily pulling out a safety pin while a handle is strongly grasped and allowing a spray hose to automatically aim a flame, and, furthermore, which is easily recognizable even from a distance when the safety pin is separated at normal times. The automatic fire extinguisher includes a main body vessel () in which a fire extinguishing agent is filled, a lower handle () coupled to a plug () disposed on an upper portion of the main body vessel (), and an upper handle () coupled to the lower handle () through a first hinge shaft ().

Automatic fire extinguisher providing user convenience

To enable a user to cook both in a pressure state and in a non-pressure state inside the inner pot and thus improve cooking quality and ease of use, the present invention provides an electric cooker including a main body in which an inner pot for accommodating food is installed; a lid coupled to the main body to be opened or closed, in which a passthrough portion is formed; a pressure converter communicating with the passthrough portion, in which a selectively opened/closed state for discharging steam inside the inner pot is maintained; and a pressure-responsive actuators communicating with the passthrough portion and selectively opened/closed depending on a pressure level inside the inner pot in a pressure cooking mode.

An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body provided, at an upper end thereof, with a flange portion and configured to accommodate an inner pot therein; a lid coupled to an upper portion of the main body and opened/closed by an opening/closing unit; a locking ring rotated by interworking with the opening/closing unit, selectively engaged with the flange portion, and provided, at an upper surface thereof, with a marker configured to indicate a rotational direction; a pressure switching unit arranged to pass through the lid and opened or closed by interworking with the opening/closing unit to discharge internal steam from the inner pot; a sensor unit configured to sense the marker when the locking ring is rotated to be locked or unlocked; and a control unit that activates power supply to the main body when a sensing signal is received from the sensor unit.

An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body configured to accommodate an inner pot; a lid coupled to an upper portion of the main body and having a handle portion provided at one side of an upper portion of the lid to interwork with an inner pot locking unit configured to lock the inner pot; a pressure switching unit arranged to pass through the lid and configured to switch or maintain an opened or closed state to discharge internal steam from the inner pot according to a rotation of the handle portion; and a pressure-responsive operating unit which is selectively opened or closed according to a pressure inside the inner pot in a pressure cooking mode in which the pressure switching unit is closed.
