Description

  The present invention relates to a safety pressure relief device and a safety pressure relief kit for a carbonated water producing machine.

  The carbonated water production machine is a machine for injecting gas into the liquid and giving the mouth feel of cider (soda water) when the liquid is used for drinking, and some household type carbonated water production machines are A carbon dioxide cylinder is used as a gas supply source, and a container for receiving a liquid is attached to a gas injection assembly of a carbonated water production machine, and is configured to inject carbon dioxide gas into the liquid by a pressurization method. For this reason, after the gas injection operation of the carbonated water production machine, the container containing the liquid is in a high pressure state, and the user must keep in mind the following matters. In other words, it is necessary to first release the pressure before removing the container. Otherwise, in the process of removing the container, a situation may occur in which liquid splatters and is ejected together with the container, resulting in danger to human safety. There is a point.

  However, the conventional carbonated water production machine does not have a mechanical design that can remove the container only after forcibly releasing the pressure, and completely relies on the user paying attention to the use procedure. Therefore, it is impossible to prevent operational mistakes and ensure the safety of the user.

  In addition, most of the conventional carbonated water producing machines can be applied only to drinking water, and cannot be directly applied to fruit juices, commercial beverages and the like. The main reason is that water and gas containing sugar cause clogging of the air vent valve. When carbon dioxide is injected into fruit juice, etc., the degree of foaming tends to be higher than when carbon dioxide is injected into drinking water, and fruit juice often flows in when air or gas is released from the air vent valve. It was. Therefore, in a carbonated water production machine with a conventional air vent valve located inside the machine body, it is difficult for the user to disassemble and clean the machine body, and it is damaged because the air vent valve is blocked after long-term use. Thus, the failure of the carbonated water production machine to function properly leads to the user having to bear the maintenance and purchase costs.

  It is preferable that high-pressure and low-pressure pressure relief valves are provided, and the trigger portions 131 and 131 ′ are provided corresponding to the respective pressure relief valves, and the pressure relief depends on the degree of operation of the unlocking unit 130. It is preferable that the state is different. For example, when the degree of operation of the unlocking unit 130 is shallow, air is mainly vented from one pressure relief valve, and when the degree of operation of the unlocking unit 130 is deep, air is vented from both pressure relief valves. If this is performed, even when the gas pressure is high, sudden degassing can be avoided and gentle degassing can be achieved.

  If comprised in this way, the degree of foaming of the drink in the pressure-resistant container 10 can be suppressed by adjusting the degree of operation of this lock release unit 130 so that a drink may not be blown down, and a pressure-resistant container When the pressure in 10 increases abnormally, the lock release unit 130 can be operated largely to release the pressure safely.
