200940926 /^pu 六、發明說明： 【發明所屬之技術領域】 本發明是有關於一種冰箱。 【先前技術】 先前’眾所周知的是具備使用例如螺線管等的開門裝 置的冰箱。開置在接收馳動命令後，對封閉著館藏 室的門施加朝向打開方向的力。另一方面，於關門時，若 門未完全咖而處於半陳態，财可能導致儲藏室内的 溫度上升。因此’已提出有具備使門確實__關門手 段的冰相（參照專利文獻1、專利文獻2)。 [專利文獻1]日本專利特開2006-57904號公報 [專利文獻2]日本專利特開昭58_142183號公報 近年來，隨著飲食生活的多樣化，家庭用冰箱的收納 ，亦在增大，超過400公升（nter)的級別成為主流，冰 箱本體的*度、寬度尺寸亦有增大的傾向。伴隨於此，旋 轉式的冷藏室Η亦在大型化，且該冷藏室門的_的收納 架亦存在深度尺寸隨著高度及寬度尺寸的擴大而增大以收 納大量食品等的傾向，再者門自身紐大之緣故，為了使 門打開’需要較大的力，從而對力氣不足的女 而言負擔增大，故而一直期望得到改善。 一 ^ 目前市場上正在供應如下的冰箱，即，由於在儲藏室 中上述冷藏室的收納容積最大，故將冷藏室的門左右分割 而設為左右對開式，或者具備自動開門裝置，該自動開^ 裝置藉由使用者對冰箱Η表面的觸碰操作錢螺線管作 200940926 動’使頂出銷（knockpin)自本體側突出來按壓n面而開 門，此類冰箱作為即使力氣弱小亦無需承擔開門的負擔的 商品而受到好評，並且已提出將該自動開門裝置應用於上 述左右對開式門的構成（例如參照專利文獻外且該 已得到商品化。 馨 上述專利文獻3等中的冷藏室用的開門裝置，由於門 f由鉸鏈（hinge)樞支的旋轉式門，故而藉由對來自作為 旋轉起點的鉸鏈部分的按壓位置、螺線管的預定產生力以

或門内側的架格的重量而使門朝關門方向轉動，從而如圖 16所示，門内侧260、260'的收納架262等會接觸到使用 者A’的身體，使人感到冷而不舒服，或者使用者觸碰到收 納的食品所灑出的汁液等而弄髒衣服。並且產生有如下的 缺點·為了防止上述問題，必須一邊用一隻手按住欲關閉 的門259、259'—邊進行取放操作，故而使用起來不方便。 其原因在於’如上所述冰箱本體251以及門259、259, 為大型構造’因此當取放收納物時，使用者A，會更靠近冰 箱本體251侧’從而導致門内側260、260,的收納架262 容易接觸到使用者（A’）A’的身體，或者同樣地，安裝於 内侧的收納架262體型大且較重，故而冷藏室門259、259' 容易因自重而關閉。再者，於冰箱本體251的上表面前部， 對應於左右的門259、259'而設有開門裝置263、263,。 【發明内容】 因此，本發明是鑒於上述問題研製而成的，其目的在 於提供一種即使因製造差異等而導致開門力不同，亦可使 藉由開門裝置而打開的門維持開門狀態的冰箱。 並且，本發明是著眼於上述問題研製而成的，其目的 在於提供一種如下所述的冰箱，即，具備使門自動打開的 開門裝置並且設置著使旋轉門靜止於任意的開門位置的門 保持裝置，藉此不僅使門自動打開，而且於取放食品等時 使門靜止而不會隨便關閉’從而提高使用方便性，並且利

Description of the invention: [Technical field to which the invention pertains] The present invention relates to a refrigerator. [Prior Art] Previously, it has been known to have a refrigerator using a door opening device such as a solenoid. The opening is applied to the door closing the collection chamber to apply a force toward the opening direction after receiving the jerk command. On the other hand, when the door is closed, if the door is not completely coffee, it will be in a semi-annual state, and the money may cause the temperature in the storage room to rise. Therefore, it has been proposed to have an ice phase in which the door is __closed (see Patent Document 1 and Patent Document 2). [Patent Document 1] Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. 58-142183. In recent years, with the diversification of eating habits, the storage of household refrigerators has also increased. The level of 400 liters (nter) has become mainstream, and the size and width of the refrigerator body have also increased. In this case, the refrigerating compartment of the refrigerating compartment is also increased in size, and the storage rack of the refrigerating compartment door also has a tendency to increase the depth dimension as the height and the width increase, so as to accommodate a large amount of food, etc. For the sake of the door itself, in order to open the door, it requires a large force, and thus the burden on the woman with insufficient strength increases, so it is expected to be improved. 1. The refrigerator is currently being supplied on the market, that is, since the storage volume of the refrigerator compartment is the largest in the storage compartment, the door of the refrigerator compartment is divided into left and right sides, and is provided with an automatic door opening device, and the automatic opening device is provided. ^ The device is operated by the user's touch on the surface of the refrigerator to operate the money solenoid for 200940926. The knockpin is protruded from the body side to press the n-face to open the door. Such a refrigerator does not need to bear even if the strength is weak. In addition, it is proposed that the automatic door opening device is applied to the above-described right and left door type (for example, it is referred to the patent document and has been commercialized.) The door opening device is a rotary door that is hinged by a hinge, and thus the pressing position from the hinge portion as the starting point of the rotation, the predetermined force of the solenoid, and the stroke of the plunger ( The pushing force generated by str〇ke) is adjusted, and the adsorption force of the magnetic sealing jaw is removed to open the door. Or, for the purpose of using a motor and a cam for the use of a rotating member and a spring, the method of using a motor and a cam is disclosed in (4) [Patent Document 3] Japanese Patent No. 388 821 (patent) Document 4] Japanese Patent No. 3864948. However, when, for example, a difference in manufacturing, storage in a gantry (d〇orpocket) = weight of a product, or a tilting of a refrigerator-like secret, the opening force of the λ will change. It’s not evenly hooked, so sometimes it’s too strong to use the door. At this point, the following problem will occur: even if you use the door opener to make the door sweat, you will pay for the full opening (4) and return to the fully closed position. (4) For a long time, there are the following problems: (4) When the door is installed from the upper door and the door is taken out from the refrigerator, and then stored, the hinge is used to support the side, so the door is opened. Under the state 200940926, the rotation of the door will not only become completely free, but sometimes the door will rotate in the direction of closing due to the weight of the door itself or the frame on the inside of the door, so as shown in Figure 16, the inside of the door 260, 260' Storage rack 262, etc. will be in contact with the use The body of A' is cold and uncomfortable, or the user touches the juice spilled from the stored food to stain the clothes, and has the following disadvantages. In order to prevent the above problem, one must use one. The hand 259, 259' is held by the hand while holding the door 259, 259' to be closed, so that it is inconvenient to use. The reason is that the refrigerator body 251 and the doors 259, 259 are large structures as described above, so when the storage and storage are taken At this time, the user A will be closer to the side of the refrigerator body 251', thereby causing the storage rack 262 of the door inner side 260, 260 to easily contact the body of the user (A') A', or similarly, the storage rack mounted to the inside. The 262 is large and heavy, so the refrigerating compartment doors 259, 259' are easily closed due to their own weight. Further, in the front portion of the upper surface of the refrigerator body 251, door opening devices 263, 263 are provided corresponding to the left and right doors 259, 259'. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a refrigerator in which a door opened by a door opening device can be maintained in an open state even if a door opening force is different due to a manufacturing difference or the like. Further, the present invention has been made in view of the above problems, and an object thereof is to provide a refrigerator having a door opening device for automatically opening a door and a door holding for repositioning the revolving door at an arbitrary door opening position. The device can not only automatically open the door, but also make the door stand still when the food is taken or not, and does not close casually, thereby improving the usability, and the use of the force of the door opening device to supplement the door holding device is inevitable 200940926 The storage room of the mouth; Π 'Set in the front center of the above body and rotate to open and close the above error = is medium =: and the door is applied to open the two ginseng two r above the door;; The rotation of the direction is set between the fully closed position and the compartment ΐ ΐ :::; ^: The levy consists of: door, seal _ door opening device, 4 in two: == operation and operation, · 5 switch actuation And to open the door action: two = ': by = form the power of intention. ^ ', the braking force of the shaft structure opens the door [the effect of the invention] The direction of the door device is such that the force required to be applied to the door by the door toward the opening of the restraining portion is greater than the opening direction Positive, and / / this 'door will * the resistance of the restricted part of the reverse rotation.

The container 207 is pivotally supported by the left and right doors 209 and 209 of the upper and lower ends of the outer side by the hinges 208 and 208', respectively, and is attached to the horizontal direction in a rotatable manner. In the door inner sides 210 and 210 forming the back surfaces of the left and right doors 209 and 209', the frame-shaped magnetic gaskets 211 and 211' are attached to the portions corresponding to the opening portions on the side of the circumference, and the left and right doors 209 are closed. At 209', the gaskets 211, 21 are adsorbed to the peripheral portion of the opening of the refrigerating chamber 202 by the magnetic force of the magnet, thereby sealing the inside and outside of the refrigerating chamber 202 in an airtight manner to prevent it. Heat leaks. In the central portion of the opening, a so-called French door type is used, that is, there are no vertical spacers for the doors 209 and 209 of both sides. Further, in the door inner sides 210 and 210 of the left and right doors 209 and 209', the storage rack 212 for storing bottles or small items is detachably provided over a plurality of upper and lower sections, and is formed when the door is opened. The food or the like is taken out from the shelf 206 in the refrigerating compartment 202 or the vegetable container 207 or placed in the shelf 206 in the refrigerating compartment 202 or in the vegetable container 2〇7, and taken out and stored in each of the storage racks described above. The bottle (pETb〇ttle) or seasoning in 212 is stored and stored. The ice storage chamber 2〇3 or the temperature switching chamber 204 disposed in the lower portion of the refrigerating chamber 202, and the cold; the east chamber 2G5 is provided with an inside of the doors 203a, 204a, and 205a that enclose the respective front openings, and extends To the depth of the storage room 19 200940926 30379pif a pair of right and left unsupported support frames 'and the containers 203b, 204b, 205b placed on the frame of the branch are made by the support frame and the inner wall of the refrigerator The slide rail mechanism is extracted with the respective doors in the front-rear direction to the outside of the refrigerator. On the front surface of the upper surface of the refrigerator body 201 corresponding to the upper end portions of the left and right doors 209 and 209', the door opening devices 213 and 213 are respectively provided by the user to the left and right doors 209, 209'. The touch switches 214, 214' of the respective handle portions of the surface perform a touch operation, and drive the respective solenoids 215 to open the door. As an example of the left door 209 is shown in the longitudinal section of FIG. 11, the door opening devices 213, 213 include. A solenoid 215 that is wound around a circumference of a cylindrical bobbin and molded by a resin, and a magnet that is attracted and moved in the axial direction by energizing the solenoid 215 The plunger 216 of the system. Further, the door opening device 213 is disposed in a state in which a part of the rubber bush 217 is embedded in the recess 218 formed in the upper portion of the refrigerator body 201. " The ejector pin 219 is attached to the front end portion of the plunger 216 as a protruding member toward the direction of the door 209. The ejector pin 219 is often in a state of abutting against the back surface of the door 2〇9 and is configured to be a spiral When the tube 215 is energized, the plunger 216 is horizontally moved forward, and the distal end portion of the ejector pin 219 protrudes in the form of the back side of the pressing door 209. A return spring 22A composed of a compression coil spring is disposed at the other end of the plunger 216, and is formed to constantly face the plunger 216 in a direction opposite to the direction of the protrusion caused by the solenoid 215. After the energization of the screw 200940926 30379pif line 215 is stopped, the ejector pin 210 is again stored in the door opening 213 by the return spring 220. Further, the door opening device ^13 of the right door also has the same configuration as the door opening device 213. Further, the surfaces of the door opening devices 213 and 213 disposed in the concave portion 218 (four) are covered and protected by a unit cover 221 . Although not shown in the drawings, a sigma switch including a reed switch (reed ❹ SWlteh) or the like is provided on the lower front portion of both sides in the refrigerating to 202 facing the back surfaces of the respective doors 209 and 209. In the case of Η, the opening and closing states of the doors 209 and 209 are detected by sensing the magnetic force of the magnetic stir seals (11) 211 and 211 which are close to each other, and the indoors are controlled not only by detecting the opening and closing of the door. The rotation of the cooling fan, the indoor lighting, etc., and the control is such that the door opening devices 213, 213' of the opened doors 209, 209' are not operated when the door is opened. Therefore, even if the door 214 or 214 is accidentally touched during the opening of the left door 209 or the right door 209, the corresponding solenoid 215 is not energized to prevent the ejector pin 219 from being ejector pin 219. The door opening devices 213 and 213 can be operated under the condition that the doors 209 and 209 are closed as a result of unexpectedly protruding into the space of the body. By the above configuration 'when the touch switches 214, 214' are touched in order to open the door 209 or 209 of the refrigerating compartment 202, the solenoid 215 of the door opening device 213 or 213 is energized, and the plunger 216 will fight back. The force of the spring 220 is attracted and protrudes toward the door side, and the ejector pin 21 仃 is moved in such a manner that it moves forward as the plunger 216 moves so that its front end abuts against the corresponding door 209 or 209. After the back, the front end is extended to the front 21 200940926 30379pif and the door is opened. Further, door holding mechanisms 222 and 222' are provided in the vicinity of the hinge portions 208 and 208' of the left and right doors 209 and 209· on the upper surface of the refrigerator body 201. The door holding mechanisms 222 and 222 are means for holding the doors 209 and 209 independently of each other at any open position, and are bilaterally symmetrical. Hereinafter, the configuration of the right door 209 and the side will be described. Figure 12 is a longitudinal sectional view, and Figure 13 is a plan view showing a door holding mechanism 222' provided on the hinge 208 of the door 209', the upper surface of the adjacent refrigerator body 201' and including the sliding block 225r formed in the casing ( The guide groove 224 in the housing 223 滑动 slides in the front-rear direction; the arc-shaped connecting link 226 moves the sliding block 225 along with the opening and closing of the door 209; and the brake block 229 The support pin 227 is rotatably supported by the frame, and is formed by the friction spring surface 229a of the sliding relationship of the side surface of the sliding block 225 by the coil spring 228 and the inclined edge 22%. When the door opening device 213' is actuated to open the door 209, as shown in Fig. 14, the link 225 is coupled to the front door 209 by the link 226. It moves and its front end corner is slid with the inclined end edge 229b of the 制动 brake pad 229 to rotate the brake block 229 against the spring force of the coil spring 228. Further, when the door 209' is made to rest at a certain degree of the door opening position which is deviated by the pressing of the door opening device 213', the frictional force generated by the engagement with the friction surface 229a is utilized to close the door. In the direction of 209 or the resistance of the external force of the two sides in the direction in which the door 209' is opened, the door 2〇9 is stopped at an arbitrary opening angle as long as the external force of the predetermined frictional force or more is not applied, and is maintained. It does not move toward the open side or the stable state of the side of the 200940926 JW/ypu off side. Further, the door holding device is not limited to the above-described configuration, and the doors 209 and 209 may be held at an arbitrary door opening angle by a simpler configuration using a torsion hinge or the like. As described above, in the large-sized refrigerator, the storage volume of the plurality of storage racks 212 formed on the inner side 21〇, 21〇 of the door tends to increase, and since the depth of the storage rack 212 is formed deep, the refrigerator compartment is formed. The length of the protrusion 突出 in the 2 〇 2 is increased, so that the position of the front end of the shelf 200 or the vegetable container 207 in the refrigerating compartment 202 is correspondingly moved rearward. As a result, when the food or the like on the shelf 206 is opened by opening the door 209 or 209', as shown in FIG. 15 which is a schematic view from the upper surface, the user A must further approach the opening of the refrigerating to 202. The hand is inserted into the front end position of the throwing plate 206 shown by the two-point chain line B in the depth of the room. In particular, the vegetable container 207 is provided as a vegetable having a relatively large width and is freely detachable. Therefore, when the vegetable container 2〇7 is withdrawn, both the left and right doors 209 and 209' must be opened. When the vegetable type ❹ is placed, the presence of the storage rack 212 protruding from the back side of the opened door 209, 209' may cause inconvenience to the user a who performs the drawing operation, that is, 'relative to the cold storage room 2' In the user A in the vicinity of the opening, the storage racks 212 and 212 of the left and right doors 2〇9 and 2〇9 in the open state are in a state close to the body, and further, the storage rack 212 is stored in the storage rack 212 due to a large amount of food. The inside causes the door to become heavier and rotates in the closing direction. Therefore, the user A has an increased chance of coming into contact with the storage rack 212 in the open state, but the root 23 200940926 30379pif is constructed as described above to the shelf 2 in the refrigerating compartment 2〇2. When the food is taken or placed in the six parts, or the doors 2〇9 and 2〇9 are opened during the extraction operation of the vegetable container 207, the Π209 or 209 can be opened, and both of them can be stopped at an arbitrary opening angle. For example, the doors 2〇9 and 2〇9 can be made to stand still in the state of Fig. 15, and the doors 209 and 209 can be kept in a stationary state as long as the user A does not move, so that it can be prevented from being stored by food or the like. The doors 209, 209' that are heavy in the storage rack 212 are rotated in the closing direction. Therefore, it is not necessary to manually stop the rotation of the doors 2〇9, 2〇9 to be closed, so that the user A can freely use the hands without obstructing the pick-and-place operation by the storage rack 212, and will not When the storage rack 212 of the doors 209 and 209 that come at the time of closing is touched, the clothes are soiled, or the low temperature portion is not touched, and it is uncomfortable, so that the food pick-and-place operation and the like can be conveniently performed. At this time, in order to make the doors 209, 209 stand at any opening position, the door holding mechanisms 222, 222' have the braking force generated by the sliding block 225 and the brake block 229. Therefore, the force for opening the door is necessarily more normal. Increased, the increased door opening force is supplemented by adjusting the generating force of the solenoids of the above-described door opening devices 213, 213, thereby having the braking force against the above-mentioned braking force, causing the doors 209, 209' to open. The force 'to reduce the load on the user a. In the above description, the case where both the doors 209 and 209' of the refrigerating compartment 2〇2 which are the left and right split type are opened is described as an example. However, the present invention is not limited thereto, and may be The case where only the left door 209 or the right door 209 is opened, and the object to be used as the door opening device and the door holding mechanism may be a storage compartment other than the refrigerating compartment, and may be applied to a single rotary door. 24 200940926 DKJD /ypiL [Brief Description of the Drawings] Fig. 1 is an exploded perspective view showing the support portion according to the first embodiment of the present invention.
