The left and right are synchronized in the operation from closing to opening of the decompression chamber lid 16 shown in FIGS. 9 to 16 or in the operation from opening to closing. For this reason, the decompression chamber lid 16 can be pulled straight without tilting.

図4、図8に示すように、減圧室蓋16の前後方向(図9から図16の紙面の左右方向)の移動を行うための部材としてガイド部材24、25が、減圧室13の左右に一対、設けられている。ガイド部材24、25は、同様な構成であるので、ガイド部材24についてのみ説明する。
ガイド部材24は、機械的性質に優れるジュラコン(ポリプラスチック(株)の登録商標)等の樹脂を用いて形成され、下面の長手方向に沿ってラックギア24gが形成されるとともに、ガイドローラ21bが案内される第1案内溝24aが、ほぼ中央部に前後方向に延設されている。
また、ガイド部材24の上部後方には、減圧室13の右側部に前方から奥方にかけて水平に延在する第2案内溝20bによって前後方向(図4、図8の紙面の左右方向)に案内されるガイドローラ24rが軸支されている。
As shown in FIGS. 4 and 8, guide members 24 and 25 are provided on the left and right sides of the decompression chamber 13 as members for moving the decompression chamber lid 16 in the front-rear direction (the left-right direction of the paper in FIGS. 9 to 16). A pair is provided. Since the guide members 24 and 25 have the same configuration, only the guide member 24 will be described.
The guide member 24 is formed using a resin such as Duracon (registered trademark of Polyplastics Co., Ltd.) having excellent mechanical properties. A rack gear 24g is formed along the longitudinal direction of the lower surface, and the guide roller 21b guides the guide member 24. The first guide groove 24a is extended substantially in the center in the front-rear direction.
In addition, behind the upper part of the guide member 24, the guide member 24 is guided in the front-rear direction (the left-right direction of the paper surface in FIGS. 4 and 8) by the second guide groove 20b extending horizontally from the front to the rear on the right side of the decompression chamber 13. A guide roller 24r is pivotally supported.

そして、減圧室13の右側方のガイド部材24の前先端部には、減圧室蓋16が支軸24s廻りに回動自在に支持されるとともに、減圧室13の左側方のガイド部材25の前先端部には、減圧室蓋16が同様な支軸廻りに回動自在に支持されている。
こうして、ガイド部材24のガイドローラ24rが、減圧室13の右側方の第2案内溝20bによって前後方向に案内されるとともに、図4、図8、図17に示すように、ガイド部材24の第1案内溝24aが、減圧室13の右前側方のガイドローラ21bにより案内されている。
このガイド部材24と同様に、左側のガイド部材25のガイドローラが、減圧室13の左側方の第2案内溝(右側の第2案内溝20bに対応)によって前後方向に案内されるとともに、図17に示すように、左側のガイド部材25の第1案内溝25aが、減圧室13の左前側方のガイドローラ21aにより案内されている。
A decompression chamber lid 16 is supported at the front end portion of the guide member 24 on the right side of the decompression chamber 13 so as to be rotatable around the support shaft 24 s, and in front of the guide member 25 on the left side of the decompression chamber 13. A decompression chamber lid 16 is supported at the tip so as to be rotatable around a similar support shaft.
In this way, the guide roller 24r of the guide member 24 is guided in the front-rear direction by the second guide groove 20b on the right side of the decompression chamber 13, and as shown in FIGS. One guide groove 24 a is guided by a guide roller 21 b on the right front side of the decompression chamber 13.
Similarly to the guide member 24, the guide roller of the left guide member 25 is guided in the front-rear direction by a second guide groove on the left side of the decompression chamber 13 (corresponding to the second guide groove 20b on the right side). As shown in FIG. 17, the first guide groove 25 a of the left guide member 25 is guided by the left front guide roller 21 a of the decompression chamber 13.

さらに、図4、図8、図17に示すように、ガイド部材24のラックギア24gとガイド部材25のラックギア25gとが、それぞれ、減圧室13の下方に回動自在に支持される回転同期軸23に固定され同期されたピニオンギア22a、22bに噛み合って、ガイド部材24、25が、左右で同期をとられ、前後方向(図9から図16の紙面の左右方向)に移動する。
この構成により、減圧室蓋16は、減圧室13に対する図9から図16に示す開閉動作における前後方向(図9から図16の紙面の左右方向)の移動において、両側方でそれぞれ2点支持されるために水平に移動できる。
加えて、減圧室蓋16は、同期された左右のピニオンギア22a、22bによる駆動により左右の同期がとられるので、水平面内において左右で傾くことなく、円滑な往復直線運動が可能である。
Furthermore, as shown in FIGS. 4, 8, and 17, the rotation synchronization shaft 23 in which the rack gear 24 g of the guide member 24 and the rack gear 25 g of the guide member 25 are rotatably supported below the decompression chamber 13, respectively. The guide members 24 and 25 are synchronized in the left and right directions and moved in the front-rear direction (the left-right direction on the paper in FIGS. 9 to 16).
With this configuration, the decompression chamber lid 16 is supported at two points on both sides in the front-rear direction (left-right direction of the paper in FIGS. 9 to 16) in the opening / closing operation shown in FIGS. 9 to 16 with respect to the decompression chamber 13. Can move horizontally to
In addition, the decompression chamber cover 16 is synchronized with the left and right pinion gears 22a and 22b by the synchronized left and right pinion gears 22a and 22b, so that the reciprocating linear motion can be smoothly performed without tilting left and right in the horizontal plane.

<<減圧室蓋16の構成>>
ガイド部材24、25の支軸24s、(25s)によって下部で回動自在に支持された減圧室蓋16は、図4、図5、図8に示すように、その両側方に設けられた支軸16s廻りに開閉ハンドル26が回動自在に支持されるとともに、図5、図6に示す差圧抜き弁Vが構成されている。
この開閉ハンドル26を、利用者が把持して、減圧室蓋16の開閉操作および減圧室蓋16の閉塞時のロックが行われるとともに、差圧抜き弁Vの開閉が行われる。
なお、差圧抜き弁Vとは、減圧室13が、真空ポンプ12によって減圧された場合、減圧室13の外部の大気圧と、減圧室13の内部の減圧された圧力との差圧によって減圧室蓋16に加わる荷重が大きくなることから、何らの手段を施すことなく、人手で、直接、減圧室蓋16を開放することは不可能である。
<< Configuration of Decompression Chamber Lid 16 >>
The decompression chamber lid 16 rotatably supported at the lower part by the support shafts 24s and (25s) of the guide members 24 and 25, as shown in FIGS. 4, 5, and 8, is provided on both sides thereof. An opening / closing handle 26 is rotatably supported around the shaft 16s, and a differential pressure relief valve V shown in FIGS. 5 and 6 is configured.
The user holds the opening / closing handle 26, and the opening / closing operation of the decompression chamber lid 16 and the locking when the decompression chamber lid 16 is closed are performed, and the differential pressure release valve V is opened / closed.
Note that the differential pressure relief valve V means that when the decompression chamber 13 is decompressed by the vacuum pump 12, the pressure is reduced by the differential pressure between the atmospheric pressure outside the decompression chamber 13 and the decompressed pressure inside the decompression chamber 13. Since the load applied to the chamber lid 16 becomes large, it is impossible to open the decompression chamber lid 16 directly by hand without applying any means.

そこで、差圧抜き弁Vによって減圧室蓋16の内外空間を挿通させ、内外圧力差を無くし差圧による荷重を解消し、減圧室蓋16を容易に開くことができるようにしている。
減圧室蓋16は、図6に示すように、閉じた際に、外郭部材14に当接する内周縁部に弾性材のパッキン16pが配設されており、該パッキン16pが外郭部材14と減圧室蓋16間のシールを行っている。
パッキン16pは、図6に示すように、その横断面が外周中央が内部側に凹む凹部16p1を有して環状に成型されている。
パッキン16pが、外郭部材14に対して減圧室蓋16が多少、傾いて閉じられた場合も、凹部16p1内に柔軟にパッキン16pが弾性変形し、その偏りを吸収し外郭部材14と減圧室蓋16間を確実にシールすることができる。なお、パッキン16pは、減圧室蓋16に設けることなく、外郭部材14側に設けることも可能である。
Therefore, the pressure reducing valve V is inserted through the inner and outer space of the decompression chamber lid 16 to eliminate the pressure difference between the inside and outside, so that the load due to the differential pressure is eliminated, and the decompression chamber lid 16 can be easily opened.
As shown in FIG. 6, when the decompression chamber lid 16 is closed, an elastic material packing 16 p is disposed on an inner peripheral edge portion that abuts the outer shell member 14, and the packing 16 p is connected to the outer shell member 14 and the decompression chamber. Sealing between the lids 16 is performed.
As shown in FIG. 6, the packing 16p is formed in an annular shape having a recess 16p1 whose cross section is recessed at the center on the inner side.
Even when the decompression chamber lid 16 is closed to be slightly inclined with respect to the outer member 14, the packing 16p is elastically deformed in the recess 16p1 and absorbs the deviation, thereby the outer member 14 and the decompression chamber lid. It is possible to reliably seal the space between the sixteen. The packing 16p can be provided on the outer member 14 side without being provided on the decompression chamber lid 16.

図4に示すように、減圧室蓋16は、外周部16gが不透明なABS等の樹脂で成型され、央部16cが減圧室13内に貯蔵された食品を視認できるように透明なAS等の樹脂で成型されている。

減圧室蓋16の中央部16c2は、図6に示すように、その外面側が、利用者の手が入り、また、開閉ハンドル26の取っ手操作部36が占める空間を有するように、内部側に凹む形状に形成されている。
As shown in FIG. 4, the decompression chamber lid 16 is formed of a resin such as ABS whose outer peripheral portion 16 g is opaque, and a transparent portion such as a transparent AS so that the central portion 16 c can visually recognize food stored in the decompression chamber 13. Molded with resin.

The space of the opening / closing handle 26 is set so that the distance between the side portions 16c1, 16c1 of the decompression chamber lid 16 and the turning locus of the rod 27 of the opening / closing handle 26 is less than a predetermined value, for example, 7 mm or less. It is formed in a shape projecting outward substantially along an arcuate trajectory along which the body 27 moves.
As shown in FIG. 6, the central portion 16c2 of the decompression chamber lid 16 is recessed on the inner side so that the outer surface of the center portion 16c2 has a space for the user's hand and the handle operating portion 36 of the opening / closing handle 26 occupies. It is formed into a shape.

19, 20, and 21 are enlarged views showing a process of locking the decompression chamber lid 16 of the decompression chamber 13, the support 28 of the opening / closing handle 26, and the opening / closing handle 26 around the lid lock guide groove member 30 shown in FIG. 9. It is.
19 is a diagram showing the unlocked state of the decompression chamber lid 16 by the opening / closing handle 26, FIG. 21 is a diagram showing the locked state of the decompression chamber lid 16 by the opening / closing handle 26, and FIG. FIG. 22 is a diagram showing a state before the lock of FIG.
Since the left lid lock guide groove member 30 has the same configuration as the right lid lock guide groove member 30, the right lid lock guide groove member 30 will be described, and the left lid lock guide groove member 30 will be described. Description is omitted.

図19、図20、図21に示すように、蓋ロック案内溝部材30は、例えば、樹脂成型された部材であり、ガイドローラ28rを側面視で曲線状の内側壁ガイド30aに接触させて案内するものである。
蓋ロック案内溝部材30の内側壁ガイド30aは、側面視で下記の形状に形成されている。
すなわち、図19に示すように、開閉ハンドル26による減圧室蓋16のロック開放状態における支軸16sとガイドローラ28rの軸心とを結ぶ直線の内側壁ガイド30aとの交点30a1と支軸16s間寸法をcとし、また、図20に示すように、開閉ハンドル26による減圧室蓋16のロック手前の支軸16sとガイドローラ28rの軸心とを結ぶ直線の内側壁ガイド30aとの交点30a2と支軸16s間寸法をbとし、また、図21に示すように、開閉ハンドル26による減圧室蓋16のロック状態における支軸16sとガイドローラ28rの軸心とを結ぶ直線の内側壁ガイド30aとの交点30a3と支軸16s間寸法をaとすると、
As shown in FIGS. 19, 20, and 21, the lid lock guide groove member 30 is, for example, a resin-molded member, and guides the guide roller 28r by contacting the curved inner wall guide 30a in a side view. To do.
The inner wall guide 30a of the lid lock guide groove member 30 is formed in the following shape in a side view.
That is, as shown in FIG. 19, the intersection 30a1 of the straight inner wall guide 30a connecting the support shaft 16s and the shaft center of the guide roller 28r in the unlocked state of the decompression chamber lid 16 by the opening / closing handle 26 is between the support shaft 16s. As shown in FIG. 20, the intersection 30a2 of the straight inner wall guide 30a connecting the support shaft 16s before the decompression chamber lid 16 is locked by the opening / closing handle 26 and the axis of the guide roller 28r, as shown in FIG. The dimension between the support shafts 16s is b, and, as shown in FIG. 21, a straight inner wall guide 30a that connects the support shaft 16s and the shaft center of the guide roller 28r when the decompression chamber lid 16 is locked by the opening / closing handle 26. If the dimension between the intersection 30a3 and the support shaft 16s is a,

このa、b、c間には、
b(ロック手前の状態(図20))> a(ロック状態(図21)) > c(ロック開放状態(図19))
の関係が成立する曲線で連続し、側面視で図19、図20、図21に示す内側壁ガイド30aの形状が形成されている。
この蓋ロック案内溝部材30の内側壁ガイド30a形状によって、図20に示す開閉ハンドル26による減圧室蓋16のロック手前の状態においては、支軸16sとガイドローラ28rの軸心とを結ぶ直線の内側壁ガイド30aとの交点30a2と支軸16s間寸法がbと最も大きいことから、図20に示すように、支持部28のガイドローラ28rが蓋ロック案内溝部材30の内側壁ガイド30aに強く当接し又はこじり、支持部28で支持される開閉ハンドル26を開閉操作する利用者に重たい感じを与え、クリック感を付与した後ロックするように、内側壁ガイド30aが形成されている。
Between a, b and c,
b (state before locking (FIG. 20))> a (locking state (FIG. 21))> c (unlocking state (FIG. 19))
The shape of the inner wall guide 30a shown in FIGS. 19, 20, and 21 is formed in a side view as viewed from the side.
Due to the shape of the inner wall guide 30a of the lid lock guide groove member 30, in the state before the decompression chamber lid 16 is locked by the opening / closing handle 26 shown in FIG. 20, a straight line connecting the support shaft 16s and the axis of the guide roller 28r is formed. Since the dimension between the intersection 30a2 with the inner wall guide 30a and the support shaft 16s is as large as b, the guide roller 28r of the support portion 28 is strong against the inner wall guide 30a of the lid lock guide groove member 30 as shown in FIG. The inner wall guide 30a is formed so as to give a heavy feeling to a user who opens or closes the opening / closing handle 26 supported by the support portion 28 by abutting or twisting, and locks after giving a click feeling.

すなわち、利用者が、開閉ハンドル26の取っ手操作部36を把持して、図20のロック手前の状態から、開閉ハンドル26の取っ手操作部36を下方へ押し下げ、図21に示すロック状態へ至った場合、
b(ロック手前の状態(図20))> a(ロック状態(図21))
の関係から、中立状態の支持部28のガイドローラ28rが蓋ロック案内溝部材30の内側壁ガイド30aをこじる、すなわち強く当接する度合いが柔らぎ、利用者の開閉ハンドル26のロックへの移行操作において、開閉ハンドル26がロック手前の状態からロック状態に引き込まれる感触を付与するように構成されている。
That is, the user grasps the handle operating portion 36 of the opening / closing handle 26 and pushes down the handle operating portion 36 of the opening / closing handle 26 downward from the state before the locking shown in FIG. 20 to reach the locked state shown in FIG. If
b (state before locking (FIG. 20))> a (locking state (FIG. 21))
Therefore, the degree to which the guide roller 28r of the support 28 in the neutral state squeezes the inner wall guide 30a of the lid lock guide groove member 30, that is, strongly abuts, softens, and the user shifts to the lock of the opening / closing handle 26. The opening / closing handle 26 is configured to give a feeling of being pulled from the state before the lock to the lock state.

そして、利用者が、開閉ハンドル26の取っ手操作部36を把持して、図20のロック手前の状態から、開閉ハンドル26の棒体27を上方へ持ち上げ、図19に示すロック開放状態へ至った場合、支軸16sとガイドローラ28rの軸心とを結ぶ直線の内側壁ガイド30aとの交点と支軸16s間寸法がaであり、ロック手前の状態(図20参照)、ロック状態(図21参照)に比べ最も小さいことから、ロック手前の重たい感触の部分を一旦通過するものの、図20の状態から図19の開状態にいたる間には支持部28のガイドローラ28rが蓋ロック案内溝部材30の内側壁ガイド30aに接触することなく、緩やかな感触で開閉ハンドル26の操作が行えるように、内側壁ガイド30aが形成されている。   Then, the user grasps the handle operating portion 36 of the opening / closing handle 26 and lifts the bar 27 of the opening / closing handle 26 upward from the state before the locking shown in FIG. 20 to reach the unlocking state shown in FIG. In this case, the dimension between the intersection of the straight inner wall guide 30a connecting the support shaft 16s and the shaft center of the guide roller 28r and the support shaft 16s is a, the state before the lock (see FIG. 20), the locked state (FIG. 21). The guide roller 28r of the support portion 28 is covered with the lid lock guide groove member during the period from the state shown in FIG. 20 to the open state shown in FIG. The inner wall guide 30a is formed so that the opening / closing handle 26 can be operated with a gentle feel without contacting the inner wall guide 30a.

<<開閉ハンドル26のロック機構の変形例>>
次に、開閉ハンドル26のロック機構の変形例について説明する。

FIG. 23 is a view showing a state before the lock according to the modified example, and FIG. 24 is a view showing the locked state.
The lid lock mechanism of the opening / closing handle 26 according to the modification has a configuration in which the guide roller 28r of the support portion 28 is changed to a notch guide of the support portion, and the inner wall guide 30a of the lid lock guide groove member 30 is changed to a guide roller. Since there is no change in the configuration other than this, the same components are indicated by adding “′” to the reference numerals of the components in the above-described embodiment, and detailed description thereof is omitted.

図22に示すように、減圧室13'の 外郭部材14'の側面壁14b'には、蓋ロック案内溝部材に代えてガイドローラr1'が回動自在に支持されている。
開閉ハンドル26'の支持部28'は、例えば、鋼板をプレス加工して製造され、支軸16s'廻りに回動自在に支持されており、一方端部にアルミ棒の棒体27'を有するとともに、他方端部側は、ガイドローラr1'を摺動させて案内するローラガイド28a'が、側面視で曲線状に形成されている。
図22に示すロック開放状態においては、開閉ハンドル26'の支持部28'のローラガイド28a'は、外郭部材14'のガイドローラr1'を完全に解放すように形成されている。
As shown in FIG. 22, a guide roller r1 ′ is rotatably supported on the side wall 14b ′ of the outer member 14 ′ of the decompression chamber 13 ′ in place of the lid lock guide groove member.
The support portion 28 'of the opening / closing handle 26' is manufactured, for example, by pressing a steel plate, and is supported so as to be rotatable around the support shaft 16s ', and has an aluminum rod 27' at one end. At the other end side, a roller guide 28a ′ that slides and guides the guide roller r1 ′ is formed in a curved shape in a side view.
In the unlocked state shown in FIG. 22, the roller guide 28a ′ of the support portion 28 ′ of the opening / closing handle 26 ′ is formed so as to completely release the guide roller r1 ′ of the outer member 14 ′.

図23に示すロック手前の状態における、外郭部材14'のガイドローラr1'とローラガイド28a'との接触点と支軸16s'との距離をb'とし、図24に示すロック状態における、外郭部材14'のガイドローラr1'とローラガイド28a'との接触点と支軸16s'との距離をa'とすると、
b'(ロック手前の状態(図23)) > a'(ロック状態(図24))
の関係になる曲線で連続するように、側面視で図22、図23、図24に示すローラガイド28a’の形状が形成されている。
変形例では、図22に示すロック開放状態において、開閉ハンドル26'の支持部28'のローラガイド28a'は、外郭部材14'のガイドローラr1'を完全に解放する以外は、実施例と同様な構成であり、同様な作用効果を得られるので、詳細な省略は説明する。
In the state before the lock shown in FIG. 23, the distance between the contact point between the guide roller r1 ′ of the outer member 14 ′ and the roller guide 28a ′ and the support shaft 16s ′ is b ′, and the outer shell in the locked state shown in FIG. When the distance between the contact point between the guide roller r1 ′ of the member 14 ′ and the roller guide 28a ′ and the support shaft 16s ′ is a ′,
b ′ (state before locking (FIG. 23))> a ′ (locking state (FIG. 24))
The shape of the roller guide 28a ′ shown in FIGS. 22, 23, and 24 is formed in a side view so as to be continuous with a curve having the above relationship.
In the modified example, in the unlocked state shown in FIG. 22, the roller guide 28a ′ of the support portion 28 ′ of the opening / closing handle 26 ′ is the same as the embodiment except that the guide roller r1 ′ of the outer member 14 ′ is completely released. Since this is a simple configuration and the same operational effects can be obtained, detailed omission will be described.

なお、前記実施例と同様に、ロック開放状態において、開閉ハンドル26'の支持部28'のローラガイド28a'が、外郭部材14'のガイドローラr1'と接触するように構成し、
b'((ロック手前の状態(図23)) > a'(ロック状態(図24)) > c'(ロック開放状態)
の関係になる曲線で連続するように、側面視で図22、図23、図24に示すローラガイド28a’の形状を形成してもよいことは言うまでもない。
As in the above embodiment, in the unlocked state, the roller guide 28a ′ of the support portion 28 ′ of the opening / closing handle 26 ′ is configured to come into contact with the guide roller r1 ′ of the outer member 14 ′.
b ′ ((the state before the lock (FIG. 23))> a ′ (the locked state (FIG. 24))> c ′ (the unlocked state)
Needless to say, the shape of the roller guide 28a ′ shown in FIGS. 22, 23, and 24 may be formed in a side view so as to be continuous with a curve having the above relationship.

<<開閉ハンドル26の付勢バネ>>
図25は、図5に示す減圧室蓋16のF−F線断面概念図であり、図26は、図5に示す減圧室蓋16のG−G線断面概念図であり、減圧室蓋16に対して開閉ハンドル26を下方に回動して減圧室蓋16を閉塞状態近くにした場合のねじりコイルバネ32の付勢力の働きを表している。
また、図27は、減圧室蓋16に対して開閉ハンドル26を回動し、ねじりコイルバネ32の付勢力が中立位置になった際の図5のG−G線断面概念図である。
図5、図25、図26に示すように、減圧室蓋16と該減圧室蓋16に支持される開閉ハンドル26との間にはねじりコイルバネ32が配設されており、該ねじりコイルバネ32は、図27に示すねじりコイルバネ32の中立位置から開閉ハンドル26を下方に回動して図21に示す減圧室蓋16のロック状態にする操作を付勢する、すなわち開閉ハンドル26を下方に付勢し、ロックする操作をアシストしている。
<< Biasing spring of the opening / closing handle 26 >>
FIG. 25 is a cross-sectional conceptual diagram of the decompression chamber lid 16 shown in FIG. 5 taken along the line F-F. FIG. 26 is a conceptual diagram of the decompression chamber lid 16 shown in FIG. On the other hand, the action of the urging force of the torsion coil spring 32 when the open / close handle 26 is rotated downward to bring the decompression chamber lid 16 close to the closed state is shown.
27 is a schematic cross-sectional view taken along the line GG of FIG. 5 when the opening / closing handle 26 is rotated with respect to the decompression chamber lid 16 and the urging force of the torsion coil spring 32 is in the neutral position.
As shown in FIGS. 5, 25, and 26, a torsion coil spring 32 is disposed between the decompression chamber lid 16 and the opening / closing handle 26 supported by the decompression chamber lid 16. 27, the operation of turning the opening / closing handle 26 downward from the neutral position of the torsion coil spring 32 shown in FIG. 27 to lock the decompression chamber lid 16 shown in FIG. 21 is energized, that is, the opening / closing handle 26 is biased downward. And assisting with the lock operation.

また、図27に示すねじりコイルバネ32の中立位置から、開閉ハンドル26を上方に回動して図19に示す減圧室蓋16のロック開放状態にする操作の範囲においては、開閉ハンドル26を上方に付勢し、開く操作をアシストしている。
図28は、減圧室蓋16に対して開閉ハンドル26を上方に回動した際のねじりコイルバネ32の付勢力の働きを示す図5の減圧室蓋16のG−G線断面概念図である。
図26、図27、図28に示すように、開閉ハンドル26は、減圧室蓋16の支軸16s廻りに回動自在に支持されており、図27に示すバネ力中立位置においては、開閉ハンドル26の回動支点の支軸16sとねじりコイルバネ32の付勢力とが同一直線状となって、開閉ハンドル26の回動支点の支軸16sとねじりコイルバネ32の付勢力間のウデの長さが0になり、開閉ハンドル26には、ねじりコイルバネ32の付勢力は働かない。
Further, in the range of operation for turning the opening / closing handle 26 upward from the neutral position of the torsion coil spring 32 shown in FIG. 27 to bring the decompression chamber lid 16 into the unlocked state shown in FIG. 19, the opening / closing handle 26 is moved upward. Energizes and assists opening operation.
FIG. 28 is a schematic cross-sectional view taken along the line GG of the decompression chamber lid 16 of FIG. 5 showing the action of the urging force of the torsion coil spring 32 when the opening / closing handle 26 is rotated upward with respect to the decompression chamber lid 16.
As shown in FIGS. 26, 27, and 28, the opening / closing handle 26 is supported so as to be rotatable around the support shaft 16s of the decompression chamber lid 16, and in the spring force neutral position shown in FIG. The fulcrum 16s of the rotation fulcrum 26 and the urging force of the torsion coil spring 32 are in the same straight line, and the length of the Ude between the fulcrum 16s of the rotation fulcrum of the opening / closing handle 26 and the urging force of the torsion coil spring 32 is 0, and the biasing force of the torsion coil spring 32 does not act on the opening / closing handle 26.

これに対して、図26に示すように、図27に示すバネ力中立位置より、開閉ハンドル26が下方に回動した場合には、ねじりコイルバネ32の白抜き矢印で表す付勢力までの開閉ハンドル26の回動支点の支軸16sからのウデの長さがu1となり、開閉ハンドル26にねじりコイルバネ32の下方への付勢力が働き、付勢力により下向きのモーメントが加わる。
一方、図28に示すように、図27に示すバネ力中立位置より、開閉ハンドル26が上方に回動した場合には、ねじりコイルバネ32の白抜き矢印で表す付勢力までの開閉ハンドル26の回動支点の支軸16sからのウデの長さがu2となり、開閉ハンドル26にねじりコイルバネ32の上方への付勢力が働き、付勢力により上向きのモーメントが加わる。
ここで、コイルバネ32が、開閉ハンドル26を上方へ回動させる付勢力は、開閉ハンドル26の自重を上回り、利用者が開閉ハンドル26から手を離した場合にも、開閉ハンドル26がコイルバネ32の付勢力により上方に回動するように構成されている。
On the other hand, as shown in FIG. 26, when the opening / closing handle 26 is rotated downward from the spring force neutral position shown in FIG. 27, the opening / closing handle up to the urging force represented by the white arrow of the torsion coil spring 32 is provided. The length of the Ude from the support shaft 16s of the rotation fulcrum 26 becomes u1, and the downward biasing force of the torsion coil spring 32 acts on the opening / closing handle 26, and a downward moment is applied by the biasing force.
On the other hand, as shown in FIG. 28, when the opening / closing handle 26 is rotated upward from the spring force neutral position shown in FIG. 27, the opening / closing handle 26 is rotated to the urging force indicated by the white arrow of the torsion coil spring 32. The length of the Ude from the support shaft 16s of the dynamic fulcrum becomes u2, and the upward biasing force of the torsion coil spring 32 acts on the opening / closing handle 26, and an upward moment is applied by the biasing force.
Here, the biasing force by which the coil spring 32 pivots the opening / closing handle 26 upwards exceeds the weight of the opening / closing handle 26, and the opening / closing handle 26 moves the coil spring 32 even when the user releases his / her hand from the opening / closing handle 26. It is configured to rotate upward by an urging force.

開閉ハンドル26における取っ手操作部36(図29参照)は、利用者が開閉ハンドル26を操作する場合の握り部の機能と、差圧抜き弁Vの開閉をガイドする機能とを有している。
図29に示すように、開閉ハンドル26における取っ手操作部36には、減圧室蓋16に回動自在に支持される弁開閉部材35の開閉ガイド35gの両辺面35g1、35g2を、その延在方向に案内する弁案内凹部30aが形成されている。
同様に、図30に示すように、開閉ハンドル26における取っ手操作部36には、弁開閉部材35の開閉ガイド35hの両辺面35h1、35h2を、その延在方向に案内する弁案内凹部30bが形成されている。
このように、開閉ハンドル26の回動による開閉操作を、弁開閉部材35を介して弁体35tの開閉弁動作に連動させることにより、開閉ハンドル26に、直接、差圧抜き弁Vの弁体を設けた場合に生じる開閉ハンドル26や減圧室蓋16の樹脂部のそり等による寸法誤差に起因する弁体の開閉動作不良を未然に防止している。
A handle operating portion 36 (see FIG. 29) in the opening / closing handle 26 has a function of a grip portion when a user operates the opening / closing handle 26 and a function of guiding opening / closing of the differential pressure relief valve V.
As shown in FIG. 29, the handle operating portion 36 of the opening / closing handle 26 has both side surfaces 35g1, 35g2 of the opening / closing guide 35g of the valve opening / closing member 35 rotatably supported by the decompression chamber lid 16, extending in the direction of extension. A valve guide recess 30a is formed to guide the valve.
Similarly, as shown in FIG. 30, the handle operating portion 36 of the opening / closing handle 26 is formed with a valve guide recess 30b for guiding both side surfaces 35h1, 35h2 of the opening / closing guide 35h of the valve opening / closing member 35 in the extending direction thereof. Has been.
As described above, the opening / closing operation by turning the opening / closing handle 26 is linked to the opening / closing valve operation of the valve body 35t via the valve opening / closing member 35, whereby the valve body of the differential pressure release valve V is directly connected to the opening / closing handle 26. The valve opening / closing operation failure due to the dimensional error due to the warp of the resin portion of the opening / closing handle 26 and the decompression chamber lid 16 that occurs when the valve is provided is prevented.

図32は、図5のD−D線断面図であり差圧抜き弁Vの閉弁状態を示しており、図33は、差圧抜き弁Vの開弁状態を示した図5のD−D線断面に相当する図である。
図32に示すように、開閉ハンドル26を矢印に示すように下方に回動して減圧室蓋16を閉塞しロックした場合には、開閉ハンドル26の寸法誤差に拘らず、開閉ハンドル26の回動操作を、開閉ハンドル26と一体で動作する弁開閉部材35によって連動させ、弁開閉部材35の弁体35tによって差圧抜き弁Vを閉弁することができる。
一方、図33に示すように、開閉ハンドル26を図32のロック状態から矢印に示すように上方に回動して開放した場合には、開閉ハンドル26の寸法誤差に拘らず、開閉ハンドル26の回動操作を、開閉ハンドル26と一体で回動する弁開閉部材35によって連動させ、弁開閉部材35の弁体35tによって差圧抜き弁Vを開弁する。
開弁した場合、図33の矢印に示すように、圧力差により外部の大気が減圧された減圧室13内に侵入し差圧が解消され、減圧室蓋16を開く際の減圧室蓋16に加わる差圧による荷重が無くなり、スムーズに減圧室蓋16を開くことができる。
32 is a cross-sectional view taken along the line DD of FIG. 5 and shows the closed state of the differential pressure relief valve V. FIG. 33 shows the open state of the differential pressure relief valve V of FIG. It is a figure equivalent to a D line section.
As shown in FIG. 32, when the opening / closing handle 26 is rotated downward as indicated by an arrow to close and lock the decompression chamber lid 16, the opening / closing handle 26 can be rotated regardless of the dimensional error of the opening / closing handle 26. The operation is interlocked by a valve opening / closing member 35 that operates integrally with the opening / closing handle 26, and the differential pressure release valve V can be closed by the valve body 35 t of the valve opening / closing member 35.
On the other hand, as shown in FIG. 33, when the opening / closing handle 26 is rotated upward from the locked state shown in FIG. The rotation operation is interlocked by a valve opening / closing member 35 that rotates integrally with the opening / closing handle 26, and the differential pressure relief valve V is opened by the valve body 35 t of the valve opening / closing member 35.
When the valve is opened, as shown by the arrow in FIG. 33, the outside air enters the decompression chamber 13 which has been decompressed by the pressure difference, the differential pressure is eliminated, and the decompression chamber lid 16 is opened when the decompression chamber lid 16 is opened. The load due to the applied differential pressure is eliminated, and the decompression chamber lid 16 can be opened smoothly.

<<開閉ハンドル26の保持機構>>
図34は、開閉ハンドル26の支持部28のツメ部28tが、減圧室蓋16のハンドル保持部材37の保持突起37tに係止して、開閉ハンドル26の下方への回動を阻止している状態を示す概念的右側面図であり、図35は、開閉ハンドル26の支持部28のツメ部28tが、減圧室蓋16のハンドル保持部材37の保持突起37tとの係止が外され、開閉ハンドル26の下方への回動の阻止が解除されている状態を示す概念的右側面図である。
図34、図35に示すように、外郭部材14の両側部には、突起状のハンドル保持解除部材39、39が固定されている。
図34に示すように、減圧室蓋16が減圧室13の外郭部材14から所定距離、離間している場合、外郭部材14の両側部のハンドル保持解除部材39、39は、減圧室蓋16のハンドル保持部材37、37から離れており、ハンドル保持部材37、37を押圧することはない。
<< Holding mechanism of opening / closing handle 26 >>
34, the claw portion 28t of the support portion 28 of the opening / closing handle 26 is engaged with the holding projection 37t of the handle holding member 37 of the decompression chamber lid 16, thereby preventing the opening / closing handle 26 from rotating downward. FIG. 35 is a conceptual right side view showing a state, and FIG. 35 shows that the claw portion 28t of the support portion 28 of the opening / closing handle 26 is disengaged from the holding projection 37t of the handle holding member 37 of the decompression chamber lid 16, FIG. 6 is a conceptual right side view showing a state in which the prevention of the downward rotation of the handle is released.

<<減圧室蓋16の蓋開閉案内機構>>
次に、減圧室蓋16の蓋開閉案内機構について説明する。
減圧室13は、図4、図9に示すように、その右側部に減圧室蓋16を、図9に示す閉じた状態から図16に示す開いた状態に開閉するための蓋開閉案内機構を備えている。
図4、図9に示すように、減圧室13の右側部に取り付けられる保護板材19には、前方から奥方に水平方向に延在する第1水平ガイド孔42aと、該第1水平ガイド孔に連続して奥方かつ下方に延在する第1傾斜ガイド孔42bと、該第1傾斜ガイド孔42bに連続し奥方に水平に延在する第2水平ガイド孔42cと、該第2水平ガイド孔42cに連続し奥方かつ上方に延在する第2傾斜ガイド孔42dと、該第2傾斜ガイド孔42dに連続し奥方に水平に延在する第3水平ガイド孔42eとを有する蓋開閉ガイド孔42が穿設されている。
第3水平ガイド孔42eの存在により、減圧室蓋16を閉じる場合に、閉じ間際に減圧室蓋16を、回動させることなく、真直ぐに移動して外郭部材14に当接させることができる。
<< Cover Opening / Closing Guide Mechanism for Decompression Chamber Lid 16 >>
Next, the lid opening / closing guide mechanism of the decompression chamber lid 16 will be described.
As shown in FIGS. 4 and 9, the decompression chamber 13 has a lid opening / closing guide mechanism for opening and closing the decompression chamber lid 16 from the closed state shown in FIG. 9 to the open state shown in FIG. I have.
As shown in FIGS. 4 and 9, the protective plate 19 attached to the right side of the decompression chamber 13 has a first horizontal guide hole 42a extending horizontally from the front to the back, and the first horizontal guide hole. A first inclined guide hole 42b that extends continuously in the back and downward, a second horizontal guide hole 42c that extends continuously in the back and continues to the first inclined guide hole 42b, and the second horizontal guide hole 42c. A lid opening / closing guide hole 42 having a second inclined guide hole 42d that extends continuously in the back and upwards, and a third horizontal guide hole 42e that continues to the second inclined guide hole 42d and extends horizontally in the back. It has been drilled.
Due to the presence of the third horizontal guide hole 42e, when the decompression chamber lid 16 is closed, the decompression chamber lid 16 can be moved straight and brought into contact with the outer member 14 without being rotated just before closing.

図8に示すように、減圧室蓋16の開閉案内機構として、第1連結リンク43が設けられており、第1連結リンク43は、その中央軸43oで、ガイド部材24に回転自在に支持される。又、中央軸43oの奥側に挿通しているガイドローラ24rは、図8に示す第2案内溝20bに案内されて前後方向に移動する。
また、第1連結リンク43は、その一方端の先端縁が曲率を有して突き出すとともに細幅に延びる形状の方向転換突部43tが形成されており、該方向転換突部43tから中央寄りには蓋開閉ガイド孔42に案内されるガイドローラ43rが軸支されており、その他方端には軸43jの廻りに第2連結リンク44の一方端が回動自在に連結されている。
図8、図18に示すように、第2連結リンク44は、前後方向に長い寸法を有しており、他方端が、開閉ハンドル26が減圧室蓋16に回動自在に支持される支軸16sに回動自在に支持されている。
As shown in FIG. 8, a first connection link 43 is provided as an opening / closing guide mechanism for the decompression chamber lid 16, and the first connection link 43 is rotatably supported by the guide member 24 at its central shaft 43o. The Further, the guide roller 24r inserted through the back side of the central shaft 43o is guided by the second guide groove 20b shown in FIG. 8 and moves in the front-rear direction.
Further, the first connecting link 43 is formed with a direction changing projection 43t having a shape in which the tip edge of one end protrudes with a curvature and extends narrowly, and the direction changing projection 43t is closer to the center. A guide roller 43r guided in the lid opening / closing guide hole 42 is pivotally supported, and one end of a second connection link 44 is rotatably connected to the other end around a shaft 43j.
As shown in FIGS. 8 and 18, the second connecting link 44 has a long dimension in the front-rear direction, and the other end is a support shaft on which the opening / closing handle 26 is rotatably supported by the decompression chamber lid 16. It is rotatably supported by 16s.

また、図4に示す減圧室13の右側部に配設される保護板材19の内面には、図8に示すV字状の方向転換ガイド部材45が固定されており、後記するように、第1連結リンク43の方向転換突部43tが、方向転換ガイド部材45のガイド面45aに案内されて、第1連結リンク43が前後方向を転換する。
図36(a)は、図9に示す減圧室蓋16を閉じるに際に減圧室蓋16が正立した状態の蓋開閉案内機構を示す概念的側面図であり、図36(b)は、減圧室蓋16を開き最大傾斜させた状態の蓋開閉案内機構を示す概念的側面図である。
Further, a V-shaped direction changing guide member 45 shown in FIG. 8 is fixed to the inner surface of the protective plate 19 disposed on the right side of the decompression chamber 13 shown in FIG. The direction change protrusion 43t of the first connection link 43 is guided by the guide surface 45a of the direction change guide member 45, and the first connection link 43 changes the front-rear direction.
36 (a) is a conceptual side view showing the lid opening / closing guide mechanism in a state where the decompression chamber lid 16 is erected when the decompression chamber lid 16 shown in FIG. 9 is closed, and FIG. FIG. 6 is a conceptual side view showing a lid opening / closing guide mechanism in a state where the decompression chamber lid 16 is opened and tilted to the maximum.

図36(a)、図36(b)に示すように、減圧室蓋16を閉じる際の減圧室蓋16の正立時、および、減圧室蓋16を開いた際の減圧室蓋16の傾斜時ともに、第2連結リンク44が支持される支軸16s(A)点および軸43j(B)点、また、第1連結リンク43が支持される中央軸43o(C)点および軸43j(B)点の(A)、(B)、(C)の3点が略一直線状に位置する。そのため、蓋開閉力Fが加えられた場合、第1連結リンク43に回転モーメントが働き難くなり、蓋開閉力Fが、ガイド部材24に設けられている(C)点に真っ直ぐ伝達されるので、ガイド部材24が水平に移動する。従って、減圧室蓋16は回転しないで、正立ないし傾斜したままの状態を保って水平に移動することができる。   36 (a) and 36 (b), when the decompression chamber lid 16 is upright when the decompression chamber lid 16 is closed, and when the decompression chamber lid 16 is inclined when the decompression chamber lid 16 is opened. Both the support shaft 16s (A) and the shaft 43j (B) on which the second connection link 44 is supported, and the central shaft 43o (C) and the shaft 43j (B) on which the first connection link 43 is supported. The three points (A), (B), and (C) are positioned in a substantially straight line. For this reason, when the lid opening / closing force F is applied, the rotational moment hardly acts on the first connecting link 43, and the lid opening / closing force F is transmitted straight to the point (C) provided in the guide member 24. The guide member 24 moves horizontally. Therefore, the decompression chamber lid 16 does not rotate and can move horizontally while maintaining an upright or inclined state.

なお、減圧室蓋16の開閉案内機構は、減圧室13の右側部にのみ設けられ、左側部に設けられていない。なお、減圧室蓋16の開閉案内機構は、右側部に設けず、左側部に設けてもよい。   The opening / closing guide mechanism for the decompression chamber lid 16 is provided only on the right side of the decompression chamber 13 and is not provided on the left side. The opening / closing guide mechanism for the decompression chamber lid 16 may be provided on the left side instead of being provided on the right side.

<<減圧室蓋16の蓋開閉案内機構による開閉過程>>
次に、前記構成の減圧室蓋16の開閉案内機構による減圧室蓋16の開閉過程について説明する。
ここで、減圧室蓋16は、図8、図17、および図18に示すように、ガイド部材24の支軸24sおよび同様なガイド部材25の支軸に回動自在に支持されるとともに、支軸16sで第2連結リンク44と回動自在に支持されている。
従って、減圧室蓋16は、ガイド部材24の支軸24sと第2連結リンク44との支軸16sが相対的に同じ水平移動を行えば、回動することなく、水平に移動することになる。
<< Opening / Closing Process by Lid Opening / Closing Guide Mechanism of Decompression Chamber Lid 16 >>
Next, the opening / closing process of the decompression chamber lid 16 by the opening / closing guide mechanism of the decompression chamber lid 16 having the above-described configuration will be described.
Here, as shown in FIGS. 8, 17, and 18, the decompression chamber lid 16 is rotatably supported by a support shaft 24s of the guide member 24 and a support shaft of a similar guide member 25, and is also supported by the support shaft 24s. The second connecting link 44 is rotatably supported by the shaft 16s.
Therefore, the decompression chamber lid 16 moves horizontally without rotating if the support shaft 24s of the guide member 24 and the support shaft 16s of the second connecting link 44 perform the same horizontal movement. .

図4、図8、図36(a)に示すように、減圧室蓋16を閉じた状態において、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の水平に延在する第3水平ガイド孔42eに位置するとともに、第1連結リンク43の中央軸43oがガイド部材24のガイドローラ24rと同心にあり図8に示す第2案内溝20bに案内されており、第1連結リンク43に連結する第2連結リンク44が、図示する位置にある。
続いて、図8に示すように、利用者が、開閉ハンドル26の取っ手操作部36を持って、矢印に示すように、上方に開閉ハンドル26を回動させて、開閉ハンドル26による減圧室蓋16のロックを解除する。
As shown in FIGS. 4, 8, and 36 (a), when the decompression chamber lid 16 is closed, the guide roller 43 r of the first connection link 43 extends horizontally to the lid opening / closing guide hole 42. The center shaft 43o of the first connection link 43 is concentric with the guide roller 24r of the guide member 24 and is guided by the second guide groove 20b shown in FIG. The second connecting link 44 to be connected is in the position shown in the figure.
Subsequently, as shown in FIG. 8, the user holds the handle operating portion 36 of the opening / closing handle 26, rotates the opening / closing handle 26 upward as indicated by the arrow, and the decompression chamber cover by the opening / closing handle 26. 16 is unlocked.

そして、図9に示すように、利用者が、開閉ハンドル26の取っ手操作部36(図4参照)を持ち、開閉ハンドル26を矢印で表した前方(図9の紙面左側)に引くと、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の水平に延在する第3水平ガイド孔42e内を前方(図9の紙面左側)に案内されるとともに、第1連結リンク43の中央軸43oがガイド部材24のガイドローラ24rと同心にあり図8に示す第2案内溝20bに案内され前方(図9の紙面左側)に前方に移動し、第1連結リンク43は、傾くことなく前方(図9の紙面左側)に移動する。
この場合、第1連結リンク43は、ガイド部材24、25(図29〜図31参照)と同じく水平に前方に向かって同じ距離を移動するため、第1連結リンク43と、軸43jで連結される第2連結リンク44は、第1連結リンク43と等距離、同方向に移動する。
そのため、ガイド部材24、25と第1連結リンク43とで支持される減圧室蓋16は、回動することなく、前方(図9の紙面左側)に、ガイド部材24、25および第1連結リンク43と等距離水平方向に前方に移動する。
Then, as shown in FIG. 9, when the user holds the handle operating portion 36 (see FIG. 4) of the opening / closing handle 26 and pulls the opening / closing handle 26 forward (left side in FIG. 9) indicated by an arrow, The guide roller 43r of the first connecting link 43 is guided forward (to the left in FIG. 9) through the third horizontal guide hole 42e extending horizontally of the lid opening / closing guide hole 42, and the central shaft of the first connecting link 43 43o is concentric with the guide roller 24r of the guide member 24, is guided by the second guide groove 20b shown in FIG. 8 and moves forward (to the left in FIG. 9), and the first connecting link 43 moves forward without tilting. Move to (left side of the paper in FIG. 9).
In this case, the first connecting link 43 is connected to the first connecting link 43 by the shaft 43j in order to move the same distance toward the front in the same horizontal direction as the guide members 24 and 25 (see FIGS. 29 to 31). The second connection link 44 moves in the same direction and the same distance as the first connection link 43.
Therefore, the decompression chamber lid 16 supported by the guide members 24 and 25 and the first connection link 43 does not rotate and moves forward (left side in FIG. 9) with the guide members 24 and 25 and the first connection link. 43 and move forward in the horizontal direction.

このように、減圧室蓋16が開く場合に、減圧室蓋13の外郭部材14と傾くことなく所定距離、水平方向に離れ、逆に、減圧室蓋16が閉じる場合に、減圧室蓋13の外郭部材14と傾くことなく水平方向に近づき、当接する。
そのため、減圧室蓋16のパッキン16pが、外郭部材14と傾くことなく離れ、また、外郭部材14と傾くことなく近づき当接するので、パッキン16pが外郭部材14にこじられることがなく、ほぼ均一に当接されるのでシール性能が高い。また、パッキン16pの劣化を防止することができる。
続いて、利用者が、開閉ハンドル26を前方(図9の紙面左側)に引くと、図10に示すように、第1連結リンク43の中央軸43oがガイド部材24のガイドローラ24rと同心にあり図8に示す第2案内溝20bに案内されて前方(図10の紙面左側)に案内されるが、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第2傾斜ガイド孔42dにより前方かつ下方に案内される。
As described above, when the decompression chamber lid 16 is opened, it is separated from the outer member 14 of the decompression chamber lid 13 in the horizontal direction by a predetermined distance, and conversely, when the decompression chamber lid 16 is closed, It approaches the abutting member 14 in the horizontal direction without inclining and abuts.
Therefore, the packing 16p of the decompression chamber lid 16 is separated from the outer member 14 without inclining, and approaches and comes into contact with the outer member 14 without inclining, so that the packing 16p is not twisted by the outer member 14 and is almost uniform. High sealing performance due to contact. Moreover, deterioration of the packing 16p can be prevented.
Subsequently, when the user pulls the opening / closing handle 26 forward (left side in FIG. 9), the central shaft 43o of the first connecting link 43 is concentric with the guide roller 24r of the guide member 24 as shown in FIG. 8 is guided in the second guide groove 20b shown in FIG. 8 and guided forward (left side in FIG. 10), but the guide roller 43r of the first connecting link 43 is in the second inclined guide hole 42d of the lid opening / closing guide hole 42. Is guided forward and downward.

この場合、図10に示すように、ガイド部材24、25(図29〜図31参照)は、前方に水平に移動するが、第1連結リンク43は、ガイドローラ43rが下方に傾き、第2連結リンク44が連結される軸43jは上方に移動する。
すると、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように回動しつつ前方に移動する。
さらに、図10の矢印に示すように、開閉ハンドル26を前方(図10の紙面左側)に引くと、図11に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図11の紙面左側)に案内されるが、第1連結リンク43の方向転換突部43tが方向転換ガイド部材45のガイド後面45a1に案内されつつ第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第2水平ガイド孔42c(図9参照)内を移動する。
In this case, as shown in FIG. 10, the guide members 24 and 25 (see FIGS. 29 to 31) move horizontally forward, but the first connection link 43 has a second guide roller 43 r that is inclined downward. The shaft 43j to which the connection link 44 is connected moves upward.
Then, the decompression chamber lid 16 connected to the second connection link 44 and the support shaft 16s moves forward while rotating so that the upper part is inclined forward.
Further, when the opening / closing handle 26 is pulled forward (left side in FIG. 10) as shown by the arrow in FIG. 10, as shown in FIG. 11, the central shaft 43o of the first connecting link 43 is 8 is guided forward (left side in FIG. 11), but the direction change protrusion 43t of the first connection link 43 is guided by the guide rear surface 45a1 of the direction change guide member 45. However, the guide roller 43r of the first connection link 43 moves in the second horizontal guide hole 42c (see FIG. 9) of the lid opening / closing guide hole 42.

この過程において、第1連結リンク43は、ガイドローラ43rが下方に傾き、第2連結リンク44が連結される軸43jは上方に移動する。
すると、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように回動しつつ前方に移動する。
続いて、図11の矢印に示すように、開閉ハンドル26を前方(図11の紙面左側)に引くと、図12に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図12の紙面左側)に案内されるが、第1連結リンク43の方向転換突部43tが方向転換ガイド部材45の凹状のガイド底面45a2に案内されるとともに第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第2水平ガイド孔42c内を移動し、第1連結リンク43が直立状態になる。
In this process, in the first connection link 43, the guide roller 43r is inclined downward, and the shaft 43j to which the second connection link 44 is connected moves upward.
Then, the decompression chamber lid 16 connected to the second connection link 44 and the support shaft 16s moves forward while rotating so that the upper part is inclined forward.
Subsequently, when the opening / closing handle 26 is pulled forward (left side in FIG. 11) as shown by the arrow in FIG. 11, as shown in FIG. 12, the central shaft 43o of the first connecting link 43 is Although guided by the second guide groove 20b shown in FIG. 8 and guided forward (left side in FIG. 12), the direction change protrusion 43t of the first connection link 43 is formed as a concave guide bottom surface 45a2 of the direction change guide member 45. The guide roller 43r of the first connection link 43 moves in the second horizontal guide hole 42c of the lid opening / closing guide hole 42, and the first connection link 43 is brought into an upright state.

この過程において、第2連結リンク44が連結される軸43jは上方に移動し、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように回動しつつ前方に移動する。
このように、減圧室蓋16が傾斜することで、減圧室13内の食品等を見易くなるとともに、減圧室蓋16を完全に引き出さなくとも減圧室13内の食品等を取り出せる。
さらに、図12の矢印に示すように、開閉ハンドル26を前方(図12の紙面左側)に引くと、図13に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図13の紙面左側)に案内されるが、第1連結リンク43の方向転換突部43tが方向転換ガイド部材45のガイド前面45a3に案内されるとともに第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第2水平ガイド孔42c内を移動し、第1連結リンク43が方向転換突部43t廻りに回動し方向転換する。
In this process, the shaft 43j to which the second connection link 44 is connected moves upward, and the decompression chamber lid 16 connected to the second connection link 44 by the support shaft 16s rotates so that the upper part is inclined forward. While moving forward.
As described above, since the decompression chamber lid 16 is inclined, the food in the decompression chamber 13 can be easily seen, and the food in the decompression chamber 13 can be taken out without completely pulling out the decompression chamber lid 16.
Furthermore, as shown by the arrow in FIG. 12, when the opening / closing handle 26 is pulled forward (left side in FIG. 12), as shown in FIG. 13, the central shaft 43o of the first connecting link 43 is 8 is guided forward (left side in FIG. 13), but the direction change projection 43t of the first connection link 43 is guided by the guide front surface 45a3 of the direction change guide member 45. At the same time, the guide roller 43r of the first connecting link 43 moves in the second horizontal guide hole 42c of the lid opening / closing guide hole 42, and the first connecting link 43 rotates around the direction changing projection 43t and changes its direction.

この過程において、第2連結リンク44が連結される軸43jは前方に移動し、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように開きつつ前方に移動する。
続いて、図13の矢印に示すように、開閉ハンドル26を前方(図13の紙面左側)に引くと、図14に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図14の紙面左側)に案内されるが、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第1傾斜ガイド孔42b内を移動し、第1連結リンク43が方向転換突部43t側を中心として、さらに回動する。
この過程において、第2連結リンク44が連結される軸43jは上方に移動し、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように回動しつつ前方に移動する。

さらに、図14の矢印に示すように、開閉ハンドル26を前方(図14の紙面左側)に引 くと、図15に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図15の紙面左側)に案内されるが、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の水平方向に延在する第1水平ガイド孔42aを案内され移動し、第1連結リンク43が回動して水平になり前方に移動する。
この過程において、第2連結リンク44が連結される軸43jは前方に移動するとともに、第2連結リンク44と支軸16sで連結される減圧室蓋16は、上部が前方に傾くように開き切り、ガイドローラ43rが蓋開閉ガイド孔42の第1水平ガイド孔42aに入った時点で開く動作が停止する。
Furthermore, as shown by the arrow in FIG. 14, when the opening / closing handle 26 is pulled forward (left side in FIG. 14), as shown in FIG. 15, the central shaft 43o of the first connecting link 43 is Although guided by the second guide groove 20b shown in FIG. 8 and guided forward (left side in FIG. 15), the guide roller 43r of the first connection link 43 extends in the horizontal direction of the lid opening / closing guide hole 42. The first horizontal guide hole 42a is guided and moved, and the first connecting link 43 is rotated to become horizontal and move forward.
In this process, the shaft 43j to which the second connection link 44 is connected moves forward, and the decompression chamber lid 16 connected to the second connection link 44 and the support shaft 16s is fully opened so that the upper part is inclined forward. When the guide roller 43r enters the first horizontal guide hole 42a of the lid opening / closing guide hole 42, the opening operation stops.

そして、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第1水平ガイド孔42a(図9参照)に移動した後は、第1連結リンク43とガイド部材24とは、等距離前方に移動するので、減圧室蓋16は開き切った状態で前方(図15の紙面左側)に移動する。
続いて、図15の矢印に示すように、開閉ハンドル26を前方(図15の紙面左側)に引くと、図16に示すように、第1連結リンク43の中央軸43oが、前記の如く、図8に示す第2案内溝20bに案内されて前方(図16の紙面左側)に案内されるが、第1連結リンク43のガイドローラ43rが蓋開閉ガイド孔42の第1水平ガイド孔42a内を案内され移動して、ガイド部材24の第1案内溝24aの縁部24a1に減圧室13の右前側方のガイドローラ21bが当接し、減圧室蓋16は開き切った状態での前方(図16の紙面左側)への移動が停止し、減圧室蓋16は全開状態となる。
以上が、蓋開閉案内機構を用いた減圧室蓋16の開く動作である。
After the guide roller 43r of the first connection link 43 moves to the first horizontal guide hole 42a (see FIG. 9) of the lid opening / closing guide hole 42, the first connection link 43 and the guide member 24 are equidistant forward. Therefore, the decompression chamber lid 16 is moved forward (left side in FIG. 15) in a fully opened state.
Subsequently, as shown by the arrow in FIG. 15, when the opening / closing handle 26 is pulled forward (left side in FIG. 15), as shown in FIG. 16, the central shaft 43o of the first connecting link 43 is Although guided by the second guide groove 20b shown in FIG. 8 and guided forward (to the left in FIG. 16), the guide roller 43r of the first connecting link 43 is in the first horizontal guide hole 42a of the lid opening / closing guide hole 42. The guide roller 21b on the right front side of the decompression chamber 13 comes into contact with the edge 24a1 of the first guide groove 24a of the guide member 24, and the decompression chamber lid 16 is opened forward (see FIG. 16 is stopped, and the decompression chamber lid 16 is fully opened.
The above is the operation of opening the decompression chamber lid 16 using the lid opening / closing guide mechanism.

図16に示す減圧室蓋16が全開状態から、図9に示す減圧室蓋16を閉じる過程は、前記の過程を逆に遷移して行われる。
ここで、図16に示すように、減圧室13が冷蔵室6などの下部に配置された場合等を考慮して、二点鎖線で示す減圧室13の底面と開閉ハンドル26間に利用者の手指の入るスペースを確保するために、減圧室蓋16の上端近傍で、利用者が開閉ハンドル26を持って減圧室蓋16の開閉操作を行う構成としている。
The process of closing the decompression chamber lid 16 shown in FIG. 9 from the fully opened state of the decompression chamber lid 16 shown in FIG. 16 is carried out by reversing the above process.
Here, as shown in FIG. 16, considering the case where the decompression chamber 13 is arranged in the lower part of the refrigerator compartment 6 or the like, the user's gap between the bottom surface of the decompression chamber 13 indicated by a two-dot chain line and the opening / closing handle 26 is In order to secure a space for a finger to enter, the user performs the opening / closing operation of the decompression chamber lid 16 with the opening / closing handle 26 in the vicinity of the upper end of the decompression chamber lid 16.

<<減圧室蓋16のロック開閉動作>>
次に、減圧室蓋16のロック開閉動作について説明する。
図37(a)は、開閉ハンドル26による減圧室蓋16のロック状態からロックを解除して、開閉ハンドル26によって減圧室蓋16を開く操作を示す右側面図であり、図37(b)から図37(d)は、開閉ハンドル26による減圧室蓋16のロック状態からロックを解除して、開閉ハンドル26によって減圧室蓋16を開く操作を開始する開閉ハンドル26廻りの機構の遷移を示す概念的側面図である。
図37(a)に示すように、減圧室蓋16で減圧室13を閉じて開閉ハンドル26によって減圧室蓋16をロックしている場合、開閉ハンドル26は、減圧室蓋16の下部に位置する。
<< Lock opening / closing operation of decompression chamber lid 16 >>
Next, the lock opening / closing operation of the decompression chamber lid 16 will be described.
FIG. 37 (a) is a right side view showing an operation of unlocking the decompression chamber lid 16 from the locked state by the opening / closing handle 26 and opening the decompression chamber lid 16 by the opening / closing handle 26, from FIG. 37 (b). FIG. 37 (d) is a conceptual diagram showing the transition of the mechanism around the opening / closing handle 26 for releasing the lock from the locked state of the decompression chamber lid 16 by the opening / closing handle 26 and starting the operation of opening the decompression chamber lid 16 by the opening / closing handle 26. FIG.
As shown in FIG. 37A, when the decompression chamber 13 is closed by the decompression chamber lid 16 and the decompression chamber lid 16 is locked by the opening / closing handle 26, the opening / closing handle 26 is positioned below the decompression chamber lid 16. .

開閉ハンドル26による減圧室蓋16のロック状態から減圧室蓋16を開く動作は、矢印α1に表すように、開閉ハンドル26を完全に一旦、上端まで持ち上げてロックを解除し、矢印α2に表すように、開閉ハンドル26を前方(図37(a)の紙面左側)に引き出す必要がある。
この過程を、図37(b)から図37(d)を用いて、説明する。
図37(b)に示すように、開閉ハンドル26による減圧室蓋16のロック状態においては、開閉ハンドル26の支持部28のガイドローラ28rが、蓋ロック案内溝部材30の内側壁ガイド30aと交点30a3(図21参照)で接触しロックされている。
The operation of opening the decompression chamber lid 16 from the locked state of the decompression chamber lid 16 by the opening / closing handle 26 is as shown by the arrow α2 when the opening / closing handle 26 is completely lifted to the upper end to release the lock as represented by the arrow α1. In addition, it is necessary to pull the opening / closing handle 26 forward (to the left side of FIG. 37A).
This process will be described with reference to FIGS. 37 (b) to 37 (d).
As shown in FIG. 37 (b), when the decompression chamber lid 16 is locked by the opening / closing handle 26, the guide roller 28r of the support portion 28 of the opening / closing handle 26 intersects with the inner wall guide 30a of the lid locking guide groove member 30. It is contacted and locked at 30a3 (see FIG. 21).

この場合、図37(b)、図35に示すように、外郭部材14の両側部のハンドル保持解除部材39、39が、減圧室蓋16のハンドル保持部材37、37を押圧しており、また、開閉ハンドル26の支持部28、29のツメ部28t、29tは上方にあり、ハンドル保持部材37、37の保持突起37tとは外れている。
この状態から、開閉ハンドル26を、図37(c)に示すように、持ち上げると、開閉ハンドル26が回動し、開閉ハンドル26の支持部28、29のツメ部28t、29tが下方に位置し、ハンドル保持部材37の保持突起37tの近くに位置する。
この場合、開閉ハンドル26は、図28に示すように、開閉ハンドル26の自重より強い力のねじりコイルバネ32の付勢力で、上昇した位置で支持されている。
In this case, as shown in FIGS. 37 (b) and 35, the handle holding release members 39 and 39 on both sides of the outer member 14 press the handle holding members 37 and 37 of the decompression chamber lid 16, and The claw portions 28t, 29t of the support portions 28, 29 of the opening / closing handle 26 are located above, and are disengaged from the holding projections 37t of the handle holding members 37, 37.
In this state, when the opening / closing handle 26 is lifted as shown in FIG. 37 (c), the opening / closing handle 26 is rotated, and the support portions 28, 29 of the opening / closing handle 26 are positioned downward. The handle holding member 37 is positioned near the holding projection 37t.
In this case, as shown in FIG. 28, the opening / closing handle 26 is supported at the raised position by the urging force of the torsion coil spring 32 having a force stronger than its own weight.

続いて、利用者が、開閉ハンドル26を持って、図37(d)の白抜き矢印に示すように、手前(図37(d)の紙面左側)に引くと、減圧室蓋16は直立状態で前方(図37(d)の紙面左側)に移動し、減圧室蓋16のハンドル保持部材37、37が、減圧室13本体側の外郭部材14の両側部のハンドル保持解除部材39、39から離れ、互いの係合が解除される。
そのため、減圧室蓋16のハンドル保持部材37、37は、ねじりコイルバネ等の弾性材で上方へ付勢されているので、上方に回動し、減圧室蓋16のハンドル保持部材37、37の保持突起37t、37tが、開閉ハンドル26の支持部28、29のツメ部28t、29tに係止し、開閉ハンドル26の下方への回動にロックがかかり、開閉ハンドル26が上端位置でロックされる。
Subsequently, when the user holds the opening / closing handle 26 and pulls it toward the front (left side in FIG. 37 (d)) as shown by the white arrow in FIG. 37 (d), the decompression chamber lid 16 is in an upright state. The handle holding members 37, 37 of the decompression chamber lid 16 are moved from the handle holding release members 39, 39 on both sides of the outer member 14 on the decompression chamber 13 main body side. They are separated and their engagement with each other is released.
Therefore, since the handle holding members 37 and 37 of the decompression chamber lid 16 are biased upward by an elastic material such as a torsion coil spring, the handle holding members 37 and 37 rotate upward to hold the handle holding members 37 and 37 of the decompression chamber lid 16. The protrusions 37t and 37t are engaged with the claw portions 28t and 29t of the support portions 28 and 29 of the opening / closing handle 26, so that the downward rotation of the opening / closing handle 26 is locked, and the opening / closing handle 26 is locked at the upper end position. .

こうして、開閉ハンドル26が上端位置でロックされたまま、図9〜図16に示すように、手前(図16の紙面左側)の全開位置まで引き出される。
次に、減圧室蓋16を開いた状態から、開閉ハンドル26によって減圧室蓋16を閉じロックする動作について、説明する。
図38(a)は、減圧室蓋16が開いた状態から、開閉ハンドル26によって減圧室蓋16をロックする動作を示す右側面図であり、図38(b)から図38(d)は、減圧室蓋16が開いた状態から開閉ハンドル26によって減圧室蓋16をロックする過程の開閉ハンドル26廻りの機構の遷移を示す概念的側面図である。
In this way, the opening / closing handle 26 is pulled out to the front (left side in FIG. 16) fully open position as shown in FIGS.
Next, the operation of closing and locking the decompression chamber lid 16 with the opening / closing handle 26 from the state in which the decompression chamber lid 16 is opened will be described.
FIG. 38 (a) is a right side view showing the operation of locking the decompression chamber lid 16 by the opening / closing handle 26 from the state in which the decompression chamber lid 16 is open. FIGS. 38 (b) to 38 (d) FIG. 6 is a conceptual side view showing the transition of the mechanism around the opening / closing handle 26 in the process of locking the decompression chamber lid 16 by the opening / closing handle 26 from the state where the decompression chamber lid 16 is open.

図38(a)に示すように、開閉ハンドル26は、減圧室蓋16が全開状態から、矢印β0に示すように、後方(図38(a)の紙面右側)に戻された後、開閉ハンドル26に何らかの機構が設けられていない場合には、破線矢印β1に示すように、開閉ハンドル26は戻されることになる。
この場合には、開閉ハンドル26の両側部の支持部28、29のガイドローラ28r、29rが、両側部の蓋ロック案内溝部材30、30内に入らないので、減圧室蓋16を閉じることが不可能になる。
従って、開閉ハンドル26は、その支持部28、29のガイドローラ28r、29rが、破線矢印β2に示すように、蓋ロック案内溝部材30、30内に入る上端位置に保持した状態で、減圧室蓋16が閉じられるように次のように構成している。
As shown in FIG. 38 (a), the opening / closing handle 26 is opened and closed after the decompression chamber lid 16 is returned to the rear (right side of the paper in FIG. 38 (a)) from the fully opened state as shown by the arrow β0. When any mechanism is not provided in 26, the opening / closing handle 26 is returned as shown by the broken line arrow β1.
In this case, since the guide rollers 28r and 29r of the support portions 28 and 29 on both sides of the opening / closing handle 26 do not enter the lid lock guide groove members 30 and 30 on both sides, the decompression chamber lid 16 can be closed. It becomes impossible.
Therefore, the opening / closing handle 26 is held in the decompression chamber in a state where the guide rollers 28r, 29r of the support portions 28, 29 are held at the upper end position entering the lid lock guide groove members 30, 30 as indicated by the broken arrow β2. The lid 16 is configured as follows so as to be closed.

前述の図37(d)に示したように、減圧室蓋16を減圧室13から所定距離離れた際に、減圧室蓋16のハンドル保持部材37、37の保持突起37t、37tが、開閉ハンドル26の支持部28、29のツメ部28t、29tに係止し、開閉ハンドル26の下方への回動にロックがかかり、開閉ハンドル26が上端位置でロックされる。
そして、この位置より、減圧室蓋16が減圧室13から離れた減圧室蓋16の開閉動作においては、減圧室13本体側の外郭部材14の両側部のハンドル保持解除部材39、39から、減圧室蓋16のハンドル保持部材37、37が離れているので、ハンドル保持解除部材39、39によって押圧されることはない。
As shown in FIG. 37 (d), when the decompression chamber lid 16 is separated from the decompression chamber 13 by a predetermined distance, the holding projections 37t and 37t of the handle retaining members 37 and 37 of the decompression chamber lid 16 are opened and closed. 26, which are engaged with the claw portions 28t and 29t of the support portions 28 and 29, the downward rotation of the open / close handle 26 is locked, and the open / close handle 26 is locked at the upper end position.
From this position, in the opening / closing operation of the decompression chamber lid 16 in which the decompression chamber lid 16 is separated from the decompression chamber 13, the handle holding release members 39, 39 on both sides of the outer member 14 on the decompression chamber 13 main body side are decompressed. Since the handle holding members 37 and 37 of the chamber lid 16 are separated from each other, they are not pressed by the handle holding release members 39 and 39.

そのため、減圧室蓋16のハンドル保持部材37、37の保持突起37t、37tが、開閉ハンドル26の支持部28、29のツメ部28t、29tに係止し、ロックされ、開閉ハンドル26が上端位置で保持された状態で、減圧室蓋16の開閉動作が行われる。
そして、減圧室蓋16が開き開閉ハンドル26が上端位置で保持された状態から、図38(b)の白抜き矢印に示すように、減圧室蓋16を閉じるため、減圧室蓋16が後方(図38(b)の紙面左側)に移動された場合、開閉ハンドル26の支持部28、29のガイドローラ28r、29rが、蓋ロック案内溝部材30、30内に入る。
Therefore, the holding projections 37t and 37t of the handle holding members 37 and 37 of the decompression chamber lid 16 are locked and locked to the claw portions 28t and 29t of the support portions 28 and 29 of the opening and closing handle 26, and the opening and closing handle 26 is in the upper end position. The decompression chamber lid 16 is opened / closed in the state held in step.
Then, from the state where the decompression chamber lid 16 is opened and the opening / closing handle 26 is held at the upper end position, as shown by the white arrow in FIG. When moved to the left side in FIG. 38B, the guide rollers 28r and 29r of the support portions 28 and 29 of the opening / closing handle 26 enter the lid lock guide groove members 30 and 30, respectively.

そして、開閉ハンドル26の支持部28、29のガイドローラ28r、29rが蓋ロック案内溝部材30、30内に入った後、図38(c)に示すように、減圧室蓋16が、閉じられるため、減圧室13の外郭部材14にさらに近づくと、減圧室蓋16のハンドル保持部材37、37が、減圧室13本体側の外郭部材14の両側部のハンドル保持解除部材39、39に押圧され、減圧室蓋16のハンドル保持部材37、37の保持突起37t、37tの開閉ハンドル26の支持部28、29のツメ部28t、29tとの係止が外され、開閉ハンドル26が上下動作可能となる。
そして、図38(d)に示すように、利用者が開閉ハンドル26を押し下げて、開閉ハンドル26の支持部28、29のガイドローラ28r、29rが蓋ロック案内溝部材30、30で案内され、開閉ハンドル26で減圧室蓋16を引き込み、減圧室蓋16を減圧室13本体側の外郭部材14にロックする。
開閉ハンドル26を押し下げることによって、減圧室蓋16の左右両側が外郭部材14に対して引き込まれるので、減圧室蓋16に部品のソリや変形があっても、確実にパッキンを外郭部材14に対して当接して良好なシール性を確保できる。
またさらに、パッキンは凹部16p1を備えているので柔軟であり、ハンドルでロックをする際にも、凹部を完全に押しつぶさない範囲までしか押し込まないように設定することで、ハンドルをロックする力が過大になることはなく、軽快にロック動作を行うことができる。
Then, after the guide rollers 28r, 29r of the support portions 28, 29 of the opening / closing handle 26 enter the lid lock guide groove members 30, 30, the decompression chamber lid 16 is closed as shown in FIG. 38 (c). Therefore, when the outer member 14 of the decompression chamber 13 is further approached, the handle holding members 37, 37 of the decompression chamber lid 16 are pressed by the handle holding release members 39, 39 on both sides of the outer member 14 on the main body side of the decompression chamber 13. The holding protrusions 37t of the handle holding members 37, 37 of the decompression chamber lid 16, the support portions 28 of the opening / closing handle 26 and the tabs 28t, 29t of the opening / closing handle 26 are released, and the opening / closing handle 26 can be moved up and down. Become.
Then, as shown in FIG. 38 (d), the user pushes down the opening / closing handle 26, and the guide rollers 28r, 29r of the support portions 28, 29 of the opening / closing handle 26 are guided by the lid lock guide groove members 30, 30, The decompression chamber lid 16 is pulled in by the opening / closing handle 26, and the decompression chamber lid 16 is locked to the outer member 14 on the decompression chamber 13 body side.
By pressing down the opening / closing handle 26, the left and right sides of the decompression chamber lid 16 are drawn into the outer member 14, so that even if the decompression chamber lid 16 is warped or deformed, the packing is securely attached to the outer member 14. To ensure good sealing performance.
Furthermore, since the packing is provided with the recess 16p1, it is flexible, and when locking with the handle, the setting force is set so that the recess is only pushed to the extent that it is not completely crushed. The lock operation can be performed lightly.

この減圧室蓋16が閉じられた後、例えば図示しない操作スイッチをユーザが押すか、あるいは冷蔵室扉6bが閉じられて図示しないドアスイッチがオンされるなどの後、真空ポンプ12の運転が開始され、減圧室13内の空気が吸引され減圧が開始される。
減圧が開始されると、減圧室蓋16は大気圧と内部の低圧との差圧によって外側から押圧され、パッキン16pはハンドルによるロックされる力以上の押圧で外郭部材14に対して押圧される。パッキン16pの凹部は密着して図26乃至図32に示した状態となり、大気圧と内部の低圧との差圧による大きな荷重により、パッキン16pが潰れて大きな面圧を生じるので、さらにシール性が良好となって、内部の負圧を維持することができる。
前記構成によれば、減圧室13の減圧室蓋16が前方に回動しつつ開かれ、かつ、減圧室13の減圧室蓋16が後側に回動しつつ閉じられるので、減圧室蓋16の開閉操作の操作性が良好であり、使い勝手が良い。
また、減圧室蓋16は、左右の同期がとられて前方または後方に移動する開閉動作が行われるので、動作信頼性が高い。
減圧室蓋16は、減圧室13の外郭部材14に正立して離間または当接するので、減圧室蓋16のパッキン16pがこじられることがなく、パッキン16pの損耗が防止されシール性能が高い。
After the decompression chamber lid 16 is closed, for example, the user presses an operation switch (not shown) or the refrigerator door 6b is closed and a door switch (not shown) is turned on, and then the operation of the vacuum pump 12 is started. Then, the air in the decompression chamber 13 is sucked and decompression is started.
When decompression is started, the decompression chamber lid 16 is pressed from the outside by the differential pressure between the atmospheric pressure and the internal low pressure, and the packing 16p is pressed against the outer member 14 by a pressing force greater than the locking force by the handle. . The recesses of the packing 16p are brought into close contact with each other, and the state shown in FIGS. 26 to 32 is obtained. Since the packing 16p is crushed by a large load due to the differential pressure between the atmospheric pressure and the internal low pressure, a large surface pressure is generated. It becomes good and the internal negative pressure can be maintained.
According to the above configuration, the decompression chamber lid 16 of the decompression chamber 13 is opened while rotating forward, and the decompression chamber lid 16 of the decompression chamber 13 is closed while pivoting rearward. The operability of the opening and closing operation is good and user-friendly.
In addition, the decompression chamber lid 16 is highly reliable in operation because the left-right synchronization is taken and the opening / closing operation of moving forward or backward is performed.
Since the decompression chamber lid 16 stands upright and separates or abuts against the outer member 14 of the decompression chamber 13, the packing 16p of the decompression chamber lid 16 is not twisted, the wear of the packing 16p is prevented, and the sealing performance is high.

<<変形例1>>
次に、変形例1について、図39を用いて説明する。なお、図39は、変形例1の冷蔵庫の減圧室13の構成を示す斜視図である。
図39に示す変形例1の冷蔵庫の減圧室13は、図4に示す実施形態の減圧室13の右側部に設けた減圧室蓋16を回動させつつ開く第1連結リンク43、第2連結リンク44等の蓋開閉案内機構を設けない構成である以外は、同様な構成であるので、実施形態と同一の符号を付して詳細な説明は省略する。
<< Modification 1 >>
Next, Modification 1 will be described with reference to FIG. FIG. 39 is a perspective view showing the configuration of the decompression chamber 13 of the refrigerator according to the first modification.
39 includes a first connection link 43 and a second connection link that open while rotating the decompression chamber lid 16 provided on the right side of the decompression chamber 13 of the embodiment shown in FIG. Since the configuration is the same except that the lid opening / closing guide mechanism such as the link 44 is not provided, the same reference numerals as those in the embodiment are given and detailed description thereof is omitted.

変形例1によれば、減圧室蓋16は、左右の同期がとられて前方または後方に移動する開閉動作が行われるので、動作信頼性が高い。
また、減圧室蓋16は、減圧室13の外郭部材14に正立して当接または離間するので、減圧室蓋16のパッキン16pがこじられることがなく、パッキン16pの損耗が防止されシール性能が高い。なお、上述の実施形態では、減圧室13を冷蔵室2に設置する構成としたが、これに限るものではない。冷凍室4に減圧室13を設置する構成であっても、上述した実施形態と同等の作用効果を奏する。又その際、減圧室扉16が傾斜しないものにも適用可能である。
According to the first modification, the decompression chamber lid 16 is opened and closed in a synchronized manner on the left and right, so that the operation reliability is high.
Further, since the decompression chamber lid 16 stands upright and contacts or separates from the outer member 14 of the decompression chamber 13, the packing 16p of the decompression chamber lid 16 is not distorted, and wear of the packing 16p is prevented and sealing performance is achieved. Is expensive. In the above-described embodiment, the decompression chamber 13 is installed in the refrigerating chamber 2, but the present invention is not limited to this. Even if it is the structure which installs the decompression chamber 13 in the freezer compartment 4, there exists an effect equivalent to embodiment mentioned above. At that time, the present invention can also be applied to a case where the decompression chamber door 16 is not inclined.

<<変形例2>>
次に、変形例2について、図40、図41を用いて説明する。なお、図40は、変形例2の減圧室13を裏面から見た平面図であり、図41は、図40のH−H線断面図である。
変形例2は、図4、図8に示す実施形態の減圧室13のガイド部材24、25のラックギアに代えて、図40、図41に示すように、ガイド部材124、125に内方に向けて水平に形成したラックギア124g、125gを設け、ラックギア124g、125g間に、略水平方向に偶数個の平歯車71、72、73、74を設けたものである。これ以外の構成は、実施形態と同様な構成であるので、実施形態と同一の符号を付して詳細な説明は省略する。
<< Modification 2 >>
Next, Modification 2 will be described with reference to FIGS. 40 and 41. 40 is a plan view of the decompression chamber 13 of Modification 2 as viewed from the back surface, and FIG. 41 is a cross-sectional view taken along the line HH of FIG.
In the second modification, instead of the rack gears of the guide members 24 and 25 of the decompression chamber 13 of the embodiment shown in FIGS. 4 and 8, the guide members 124 and 125 are directed inward as shown in FIGS.
