Description

The present invention is intended for a nap room used by a general household or company staff, etc., and when the occurrence of a fire is detected, the device operates immediately and enables fully automatic initial fire extinguishment regardless of residents' responses. The present invention relates to an initial fire extinguishing sprinkler.

  Many of the fatal accidents due to fires in ordinary households that have been reported recently are elderly people or children. As a countermeasure, the government obliges new houses to install fire detection alarms and encourages ordinary households to install them. is doing. However, even if a fire occurs and the detector is activated, the behavior of the person who hears the generated sound is not predicted.In reality, the elderly and children panic and escape without knowing how to deal with them. Considering this fact, a fatal accident will be delayed, but even if an alarm is issued, the halfway measure of leaving the response to the resident is not a solution for a fatal accident due to fire, so how to fully automate all the responses Considering whether such a response is optimal, sprinklers are installed in each room at hotels etc., but the problem is solved, but this system is expensive to install, so it can not be installed in ordinary houses Close to.

  In ordinary houses, hand-held fire extinguishers and spray fire extinguishers are commercially available for initial fire extinguishment in the event of a fire.

  Equipment on the market, such as hand-held fire extinguishers and fire-fighting cylinders, are all equipment for initial fire fighting in the event of a fire, and all must be operated by the residents of the house.

  Initial fire extinguishment is the most important issue in the event of a fire, but it is helpful to reduce the number of fatal accidents by proposing a method to solve the current situation where it is difficult and difficult to solve the problem by leaving the essential fire extinguishing measures to the residents. I hoped this equipment was developed.

Problems to be solved by the invention

All the initial fire extinguishing at the time of the conventional fire was left to the resident's disposal activities, so it was not a solution for resident death.

  In view of the above-mentioned conventional drawbacks, the present invention has a function of a sprinkler device for business use for a general household that can automatically extinguish the equipment installed automatically at the same time when a fire occurs, without leaving it to a person. The object is to provide a sprinkler for initial fire fighting that is provided at low cost and does not require modification of a house.

Means for solving the problem

  In order to achieve the above object, the present invention investigated how much water is required for the intended initial fire extinguishing and what is the minimum operating time.

  In this case, if the sprinkler is directly connected to the water supply, a sufficient amount of water can be obtained for extinguishing the fire. However, this method requires a contractor to perform the construction and causes a problem in terms of cost. I experimented on how much water is needed for the initial fire extinguishing. As a result, it was possible to achieve the purpose by spraying the water in the form of mist into a 10 tatami room for about 3 minutes. For example, a 20 liter plastic tank can be used.

  With this level of construction, it is easy to complete all the construction yourself without having to ask the contractor to install the equipment, and if you have knowledge of the large scale of Sunday, and the required rooms will change. However, the device can be easily moved. By installing the system device of the present invention that can be installed by yourself, an inexpensive automatic initial fire extinguishing device can be installed even in ordinary homes.

  In order to achieve the above-mentioned object, the present invention is to be used by making some modifications to the products that meet the required functions of the present invention among the products that have already been mass-produced and are offered in large quantities on the market. Therefore, it has become possible to provide users with an inexpensive device by avoiding the waste of manufacturing as a dedicated part from the beginning at the expense of development costs.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are only for explanation and do not limit the technical scope of the present invention.

  Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

  In the first embodiment of the present invention shown in FIGS. 1 and 2, a household water storage plastic tank prepared for storing fire-extinguishing water, 1), and a motor built-in for sucking up this water are incorporated. Household bus pump, 2) AC adapter power supply for operating the system, 3) Sprinkler connection hose for ensuring water flow, 4), Fire detection that detects fire and generates alarm sound 5) and a rotary sprinkler head for discharging water from the hose that has been subjected to water pressure into a mist, from the center of the installed ceiling, 6) and a device for controlling these operations This is a combination of the control box 7) and the prevention unit 8) for the purpose of preventing the air-lock phenomenon that water cannot be sucked up when water and air are mixed in the hose. The device is configured.

  The installation of each part from 1) to 8) will be explained. First, the poly tank of 1) is placed in an appropriate place on the outer periphery of the room where the equipment is installed, and then the AC adapter-power supply 3 with the power cord is attached. ) Is connected to the poly tank 1), and the power cord plug is connected to the room outlet. Next, the hose 4) to which the air-lock prevention unit 8) is attached is connected to the bus pump 2), then the fire detector 5) is attached to the vicinity of the center of the ceiling of the room, and the detection code is attached to the operation box 7 Finally, the rotary sprinkler head 6) is attached near the center of the ceiling, the hose 4) is connected, and the hose is fixed to the ceiling and the side wall by clamps to complete the installation work. .

  Next, the procedure for making this device operable will be described.

1) Fill the poly tank with tap water, then remove the one-touch coupling valve of the air-lock preventer 8) and put the bus pump 2) into the tank to fill the pump with water. Connect the power cord 11) of the AC adapter-power source 3) to the household outlet 12) in the room.
The device has been set to the operation standby state.

Next, the procedure of the operation test will be described. There are the following three types of fire detectors on the market.
1) Heat sensing type; this works when the room temperature rises due to fire.
2) Smoke detection type; this works by detecting smoke in the event of a fire.
3) Light-sensitive type; this works by detecting the ultraviolet rays generated by the fire.

  When choosing a detector, you should consider which method to detect the fire first when a fire breaks out, but it is necessary to consider the state of the house and the installation location. It seems that the heat detection method is appropriate for the kitchen that is often used, but the smoke detection method seems appropriate because it tends to generate smoke in the bedroom.

  First, when the switch of the operation box is tilted to the test side, the power supply of the pump is automatically activated and the water in the poly tank is sent out, and the rotating water discharge is started from the tip of the sprinkler, so the operation stops if the switch is turned off immediately. Then, when the fire detector is activated after the switch of the operation box is moved to the standby side (the smoke detector applies the smoke of smoke), the same operation state is reproduced, and the switch of the operation box is usually operated. Set to the standby position.

Different embodiments of the invention

  If a fire breaks out in the event of a power outage, the automatic fire extinguishing function, which is the greatest feature of the present invention, cannot be exhibited, so the following method can be taken as a countermeasure.

  As described in [Claim 2], it is possible to take measures against power failure by stopping the AC adapter power source and using a small seal battery and always performing the float charging.

The invention's effect

As is clear from the above description, the present invention has the following effects.
(1) Since it is composed of the constituent features of [Claim 1], by combining general products existing in the market, the initial investment for development is suppressed as much as possible, and inexpensive practical products are provided to general households. Becomes a decisive factor for solving problems.
(2) Since it is composed of the constituent features of [Claim 2], it is possible to immediately cope with the required installation conditions.
(3) In [Claim 3], the problem solving method at the time of power failure in [Claim 1] was established.
(4) In [Claim 4], the number of small holes drilled in a line on the side surface of the pipe is increased or decreased by moving the position of the sleeve of the rotating pipe according to the size of the room to be installed. The water discharge distance changed and it became possible to select the optimal watering distance.

  As a result of the effects of the invention as described above, the biggest problem at the time of the current fire occurrence, that is, even if an alarm is issued, the problem that the initial fire extinguishing measures are left to the resident's action, resulting in the occurrence of victims, Until the initial fire extinguishing, all the equipment is left up to the machine equipment, and then the resident can afford to respond to the fire, so the effect of the present invention is exhibited against the occurrence of fire.
