Abstract

A safe pressure-release device for household pressure cooker has a pressure-release place which is provided with a joint hole on a cooker cover. A pressure-release seal-chip is sealed on the joint hole. The pressure-release seal-chip can be riveted on the cooker cover. One end of the pressure-release seal-chip can also be riveted together with the cooker cover, and the other end of it can be made up into the piston, so as to seal the joint hole. When the pressure inside the cooker is within the normal pressure, the pressure-release seal-chip seals the joint hole. When the pressure inside the cooker is too high, either the pressure-release seal-chip is broken down, or the piston is sprung, so the pressure is released from the joint hole.

Description

一种家庭式压力快锅之泄压装置 技术领域  TECHNICAL FIELD
本发明糸与压力快锅之安全装置有关，更详而言之，糸指一种 家庭式压力快锅之安全泄压装置。 属日常生活用品。  The present invention is related to the safety device of a pressure cooker, and more specifically, it refers to a safety pressure relief device of a family pressure cooker. Is a daily necessities.
背景技术 Background technique
目前就厨房用之蒸煮器具而言，蒸气式压力快锅（俗称 "高压 锅")就比没有压力式的节省约 80%的能源及时间。 但一般的家庭 主妇对快锅多少产生抗拒的心理，理由是快锅至目前为止常发生爆 炸。 目前国内外市面上的快锅，即使是品质安全性较高的意大利国 家制迨的快锅，也常发生爆炸事件，致使人体受伤害。  As far as cooking appliances for kitchens are concerned, the steam pressure cooker (commonly known as "pressure cooker") saves about 80% of energy and time than the pressureless cooker. However, the average housewife is more or less resistant to the quick pot, the reason is that the quick pot has been exploded so far. At present, even in the fast cookers on the market at home and abroad, even the Italian state-made ravioli cookers with high quality and safety, explosions often occur, causing injuries to human bodies.
上述发生爆炸之快锅，其发生意外不外乎有下列原因： 一、蒸气压力之通气孔，若清洁不当，或完全没有处理之状况 下，或是煮较多渣的东西，如绿豆汤等，致使该等排气阀（门）很容易 被阻塞，此一状况导致排气阀无法泄压。  The explosion of the above-mentioned fast cooker may be caused by the following reasons: 1. The vent hole of the steam pressure, if it is not cleaned properly or is not handled at all, or it is cooked with more residue, such as mung bean soup As a result, the exhaust valves (doors) are easily blocked, which causes the exhaust valves to fail to release pressure.
二、使用不当的方式燃烧加温，如使用快速炉，致使锅内产生的 压力速度容量远超过安全排气阀所能够承受的排气量，结果压力不 正常的持续增加到相当大的压力。  2. Improper combustion and heating, such as the use of a fast-fired furnace, causes the pressure velocity capacity generated in the pot to far exceed the amount of exhaust gas that the safety exhaust valve can withstand, and the abnormal pressure continues to increase to a considerable pressure.
这两种原因导致产生大量压力，最后会使锅盖与锅体之间密封 的附套，即胶质套环破裂，而达到泄压的作用。  These two causes lead to a large amount of pressure, which will eventually rupture the sealed sleeve between the lid and the pot body, that is, the rubber collar, to achieve pressure relief.
问題就出在这里，当大量高温高压的蒸气由胶质套环宣泄出 时，由于套环必须是能够承受较大的压力，因此等到套环破裂将蒸 气泄出时，此时锅盖容易被弹跳出，而锅内的大量高温蒸气，则立即 往四方喷射，很容易迨成烫伤及击伤人。  The problem is here, when a large amount of high-temperature and high-pressure steam is released from the colloidal collar, because the collar must be able to withstand a large pressure, so when the collar ruptures and the steam is released, the lid is easy to be caught at this time. It bounces out, and the large amount of high-temperature steam in the pot is immediately sprayed to the four sides, which is easy to cause burns and injuries.
发明内容 Summary of the Invention
为了克服上述缺点，本发明的目的是：设计一种家庭式快锅之 安全泄压装置，用于保护使用者的人身安全。  In order to overcome the above disadvantages, the object of the present invention is to design a safety pressure relief device for a household quick cooker to protect the personal safety of users.
本发明的家庭式快锅之全泄压装置，主要包含有一锅盖，一锅 体，锅盖上设有蒸气控制活门及一排气阀和一泄压装置，该泄压装 置于锅内压力达到预设程度时，即会受压形成穿孔提供泄除锅内压 力。 该泄压装置是在锅盖上设置一个接合孔，在接合孔上固定一个 泄压封片，该泄压封片可以自锅盖底面向上固接封住接合孔，在锅 内呈常压状态时，该泄压封片保持密封状态，当锅内的压力超压时， 泄压封片击穿，泄除锅内压力，避免爆炸伤人。该泄压封片 可以制 成一活动式弹力活塞，一端固接在锅盖上，另一端为锅幕的接合端， 活塞埋设在接合孔内，当锅内压力呈常压时，活塞堵住接合孔，锅内 压力超压时，活塞被气压项推掀开，气压由接合孔泄除。 The full pressure relief device of the household quick cooker according to the present invention mainly includes a pot lid and a pot body. The pot lid is provided with a steam control valve, an exhaust valve and a pressure relief device. When the pressure in the pot reaches a preset level, it will be pressured to form a perforation to relieve the pressure in the pot. The pressure relief device is provided with a joint hole in the pot lid, and a pressure relief cover sheet is fixed on the joint hole. The pressure relief cover sheet can be fixedly sealed from the bottom face of the pot lid to seal the joint hole. At this time, the pressure-relieving sealing sheet is kept in a sealed state. When the pressure in the pot is over-pressured, the pressure-releasing sealing sheet is broken down, the pressure in the pot is relieved, and the explosion is avoided to hurt people. The pressure relief sealing piece can be made into a movable elastic piston, one end of which is fixed to the pot lid, and the other end is the joint end of the pot curtain. The piston is buried in the joint hole. When the pressure in the pot is normal, the piston is blocked. The joint hole, when the pressure in the pot is overpressure, the piston is pushed open by the air pressure item, and the air pressure is released from the joint hole.
本发明的优点是：结构简单，使用安全。  The invention has the advantages of simple structure and safe use.

本发明的最佳实施方式 Best Mode of the Invention
兹举一较佳实施例并配合附图说明如下：  A preferred embodiment is described below with reference to the drawings:
如图所示，本发明之一种家庭式压力快锅安全泄压装置，其糸 包含一锅盖（10)及一锅体 (20)，同时，该锅盖（10)上方设有一蒸气 控制活门（11)及一排气阀（12)，设一泄压装置（14) ,该泄压装置 ( 14)于该锅盖（10)之预设位置设置一接合孔（13)，于该接合孔 ( 13) ,接设一泄压封片（141) ,该泄压封片（141)糸一自周缘向中心 渐薄之片体，该泄压部位糸设于该泄压封片（141)上，该泄压封片 (141)放在锅盖（10)底方接设于该接合孔（13)内，并露出于锅盖 (10)之上，同时并设以铆钉（16)加设垫 ffi (15)接合，据以昉止当锅 内处于负压状态时，该泄压装置（14)因此掉落于锅内。当然，也可直 接以烊接方式固接。 As shown in the figure, a household pressure quick cooker safety pressure relief device of the present invention includes a pot lid (10) and a pot body (20), and a steam control is provided above the pot lid (10). The valve (11) and an exhaust valve (12) are provided with a pressure relief device (14). The pressure relief device (14) is provided with a joint hole (13) at a preset position of the pot lid (10), and The joint hole (13) is connected with a pressure relief seal (141). The pressure relief seal (141) is a piece that is thinner from the periphery to the center, and the pressure relief portion is provided on the pressure relief seal ( 141), the pressure relief sealing piece (141) is placed on the bottom of the pot lid (10) and is arranged in the joint hole (13), and is exposed on the pot lid (10), and is also provided with a rivet (16) ) Add a pad ffi (15) to join, so as to stop being a pot When the inside is in a negative pressure state, the pressure relief device (14) thus falls into the pot. Of course, it can also be directly fixed in a spliced manner.
上述之实施例的泄压封片，原则上是没有通气孔，即使有也是 徵小的通气孔。  The pressure-relieving sealing sheet of the above-mentioned embodiment has no vent holes in principle, and even if there are vent holes, the vent holes are small.
假设压力锅在使用时，正常的压力在 10〜： 15磅（4. 54〜6. 81 公斤）之间。 当所有的排气阀被阻塞或是燃烧不当所造成过度高温 及压力，超过排气阀的承受能力，致使锅内的压力已逐渐从正常的 10〜： 15磅开始增加时，传统的压力锅，就只能靠锅盖附件胶质套环 破裂来宣泄压力。  Assuming that the pressure cooker is in use, the normal pressure is between 10 ~: 15 pounds (4.54 ~ 6. 81 kg). When all the exhaust valves are blocked or caused by excessive combustion due to excessive heat and pressure, which exceeds the capacity of the exhaust valves, the pressure in the pot has gradually increased from the normal 10 ~: 15 pounds, the traditional pressure cooker, The pressure can only be relieved by the rupture of the gel collar attached to the lid.
光靠锅盖与锅体全面密封的胶质环破裂来泄压会产生极大的 危险。 所以本发明所设计的上述安全泄压装置，糸设定在当压力超 过 15磅以后一点点，还没超过 20磅以前，此一安全泄压装置就会 自动破裂，而达到泄压的效果，而不必让压力持续增加到很大时，才 利用锅盖与锅体全面密封的胶质套环破裂来泄压。  It is extremely dangerous to release pressure by relying solely on the rubber ring that is completely sealed between the lid and the body. Therefore, the above-mentioned safety pressure relief device designed by the present invention is set to a little after the pressure exceeds 15 pounds and before it exceeds 20 pounds, this safety pressure relief device will automatically rupture and achieve the effect of pressure relief. It is not necessary to allow the pressure to continue to increase to a great extent, and then the pressure is released by using the rupture of the rubber sleeve that is fully sealed between the lid and the body.
为了使此一安全泄压装置（14)，能在正常压力超过一点点时， 就产生破裂来达到泄压的作用，所以设计上可以利用适当材料来制 迨，如以薄片之铜或铝以及塑胶料，但为了防止有毒性以及美观，可 用无毒性之塑胶料。  In order to make this safety pressure relief device (14), when the normal pressure exceeds a little bit, it will rupture to achieve the pressure relief effect, so the design can be made of appropriate materials, such as sheet copper or aluminum and Plastic materials, but in order to prevent toxicity and aesthetics, non-toxic plastic materials can be used.
同时，为了使此一泄压装置（14)在破裂时不会产生碎片，以免 伤人，设计上采用周围的材料较厚，中间较薄。  At the same time, in order that this pressure relief device (14) will not generate fragments when it is broken, so as not to hurt people, the surrounding material is designed to be thicker and the middle is thinner.
因此，当传统之压力锅其压力到达某一极限时，若排气阀（12) 及蒸气活门（11)皆因使用不当而无法泄压，那么本发明之泄压装置 (14) 自动破裂、宣泄积沉之压力，达到全面防止压力快锅爆炸伤 人事故。  Therefore, when the pressure of a traditional pressure cooker reaches a certain limit, if the exhaust valve (12) and the steam valve (11) cannot be released due to improper use, the pressure relief device (14) of the present invention will automatically rupture and vent. The accumulated pressure can prevent the injuries caused by the explosion of the pressure cooker.
本发明的另一实施例是在该泄压装置（14)之泄压封片（141)上 以一铆钉（142)将泄压封片（141)之一端与锅盖固定接合，藉以昉止 泄压封片（141)全部脱离锅盖而击伤使用者，该泄压封片（141)之另 一端与锅盖之接合点呈一活动塞式的弹力活塞（143) ,当压力超过 正常值时，此弹力活塞（143)将被压力项推弹跳而出，使该泄压封片 (141)之一端克服与锅盖接合之作用力，而得以被掀开，据此锅内造 成穿孔状态，得以宣泄积塞之压力，昉止意外发生。 According to another embodiment of the present invention, a rivet (142) is used to fix one end of the pressure relief seal (141) to the pot lid on the pressure relief seal (141) of the pressure relief device (14), thereby stopping The pressure-releasing seal (141) is completely detached from the pot lid and hurts the user. The other end of the pressure-releasing seal (141) and the joint of the pot lid are a movable plug-type elastic piston (143). When the pressure exceeds normal Value, the elastic piston (143) will be pushed and bounced out by the pressure item, so that the pressure relief sheet One end of (141) overcomes the force of engagement with the lid, and can be lifted off, thereby causing a perforated state in the pot, which can release the pressure of the plug and prevent accidents.
当然上述之实施例中，除利用铆钉（142)固定外， 可以利用如 链条来拴住该泄压封片（141)。  Of course, in the above-mentioned embodiment, in addition to being fixed by rivets (142), the pressure relief seal (141) can be fastened by, for example, a chain.
还有除了锅盖上新设有泄压封片（141)外，同时 可利用传统 之排气阀来作弹跳出之装置，即传统之排气阀只单纯的利用排气孔 来排气，当排气孔被完全塞住时，就失去排气作用，当压力持续不断 增加到很大时，传统的压力锅，就利用锅盖与锅体的全面密封橡胶 套环破裂来宣泄压力。 所以本发明认为亦可利用传统之排气阀，不 要让它完全镇死，当排气孔被完全阻塞住时，此排气阀亦可像第二 种实施一样被弹跳出。  In addition to the new pressure relief cover (141) on the lid, the traditional exhaust valve can also be used as a pop-out device. That is, the traditional exhaust valve only uses the exhaust hole to exhaust. When the exhaust hole is completely plugged, the exhaust effect is lost. When the pressure continues to increase to a great extent, the traditional pressure cooker uses the full sealing rubber sleeve of the pot lid and the pot body to rupture to release the pressure. Therefore, the present invention considers that a conventional exhaust valve can also be used instead of being completely killed. When the exhaust hole is completely blocked, the exhaust valve can also be popped out like the second implementation.
工业应用性 Industrial applicability
如上所述，本发明的家庭式压力快锅之安全装置安装在压力快 锅上，当锅内的压力超压时，泄压封片被击穿，锅内压力泄除，从而 避免锅爆炸伤人。 而且，本发明的安全装置结枸簡单，工作可靠，安 全性能良好。  As described above, the safety device of the household pressure cooker of the present invention is installed on the pressure cooker. When the pressure in the pot is overpressure, the pressure relief seal is broken and the pressure in the pot is released, thereby avoiding the explosion injury of the pot people. Moreover, the safety device of the present invention is simple to set, safe to work, and good in safety performance.
