此處’以房屋牆壁並未靠近冰箱10而設置的情形為例來進 行說明。 • 當自門操作部21輸入開門的命令時，開門裝置24將 門17向前方推出。亦即，開門裝置24對門π施加正旋轉 方向的力。藉此，門17以鉸鏈28為中心而正旋轉，從而 打開冷藏室12。此時，開門裝置24對門π施加充足的力。 因此，設於門17上的門擋30的爪部34將解除與鉸鏈28 的卡止銷32的咬合。與此同時’與固定凸輪29的凹部41 以及凹部42相咬合的門擋30的凸部36將越過凹部41以 及凹部42。此外，因開門裝置24對門17施加充足的力， 13 1361878 30379pif 71 72' ^ 止。當H 17 ϋ 門17正旋轉至全開位置為 與固定凸輪29的止時’門擋3G的凸部36 與凹部51及凹畔52相咬合。藉由凸部36 使於開Π裝置24對門17所施加:力較Γ: 侍變為全開的門17因反作 較大而使

Π的逆旋轉。因此，可使門17在全開位置或者半開位置 上維持於開門狀態。 藉由設於門擔30上的凸部36與設於固定凸輪29上 的凹部41、42、5卜52、6卜62、7卜72的咬合，可限制 門Π的逆旋轉。因此，限制部25的構成得到簡化。因此， 可在不使構造複雜化的情況下維持門17的打開狀態。 (第2實施形態） 根據圖6以及圖7，對本發明的第2實施形態的冰箱 進行說明。於第2實施形態中，冰箱與第丨實施形態的冰 箱ίο的不同點在於，包括可上下移動的可動凸輪129、以 及朝下方按壓可動凸輪129的彈性構件η!。 於第2實施形態的情形時，支撐部ι27如圖6所示， 包括鉸鏈28、固定凸輪29、門擋130、可動凸輪129以及 彈性構件111。亦即，於第2實施形態的情形時，於門擋 130中，第1實施形態的門擋3〇的筒部33被分離開來。 並且，於第2實施形態的情形時，與門擋13〇分開而形成 的筒狀的可動凸輪129可在設於門π上的門孔35的内部 上下移動。 可動凸輪129包括筒部133、凸部136以及肋部137。 133形成為筒狀，於内側插入有錢鍵銷31。並且，可 動凸輪129的肋部137設置於門π上所形成的門孔35中 15 1361878 30379pif 而可朝門孔％的轴方向移動 的肋部137 #

使可動凸輪129的凸部136與固定凸輪29的凹部41、42、 51 52'61、62、71、72中的任一者相向時，可動凸輪129 與固定凸輪29的相對旋轉受到限制。與第1實施形態相 同，如圖7所示，當門17處於預定的打開角度時，凸部 1361878 30379pif 136 與凹部 41、42、5〗、q α 相咬合。並且，當可動凸^6。1、62、71、72中的任一者 29的凹部4卜42、51、52 61的6凸部136越過固定凸輪 輪峨彈性構件⑴而朝二動7:可7=:凸 對於門17而可朝上下方向移動。因此，可 部136越過固定凸輪29的凹部41、429 :凸 7卜72時、或者可動凸輪129的凸部136 m二、51、52、61、62、71、72相咬合時所產生9 =構129與門17的相對移動，亦即藉 冓件111的伸縮而被吸收。其結果 的凸部m越過_輪29的凹部41、42 =、7卜72時、或者可動凸輪129的凸部13 9 的凹部 41、42、51、52、61、62、71、72中= 相咬合時所產生的振動，不會傳遞至Η 17以及支撐門17 的未圖示的上方的支撐部126以及下方的支撐部127。 於第2實施形態中，與固定凸輪29的凹部41、42、 51、52'61、62、7卜72咬合的凸部136設於可相對於門 17而移動的可動凸輪129上。因此，凹部41、42、51、^、 2 71、72與凸部136相咬合或者解除咬合時所產生 ，振動會藉由可動凸輪129的移動而被吸收。因此，因凹 # 41、42、5卜52、6卜62、71、72與凸部136的咬合所 產生的門17的振動得到減輕，從而可提高門Η以及支撑 門17的未圖示的上方的支撐部126以及下方的支撐部127 的耐久性。· 17 Ϊ361878 30379pif (其他實施形態） 於第1實施形態中’說明了將凸部36設於門擋30上 的示例，但是凸部36亦可設於門17上。並且，於第i實 施形態中，說明了將凹部41、42、51、52、61、62、71、 72设於固定凸輪29上的不例，但是凹部々I、42、51、52、 61、62、7卜72亦可設於鉸鏈28上。並且，設置著凹部 41、42 ' 51 ' 52 ' 6卜62、7卜72的門17的打開角度並 不受第1實施形態的示例所限，亦可任意設定。 於第1實施形態以及第2實施形態中，說明了將本發 明應用於封閉冷藏室12的右侧的門17的示例。但是並不 限於冷藏室12的右側的門17,而亦可應用於左側的門16。 此外’本發明亦可應用於在冷藏室12的前方設有一扇門的 單開式的冰箱。 以下，根據圖式，對本發明的第3實施形態進行說明。 圖8是本發明的冰箱的正面外觀圖，圖9是表示打開左右

Further, in the case of the force in the direction of the condensation, the claw portion and the non-card are applied. When the main door 17 is applied to the crucible, the refrigerating chamber 12 is opened and the engagement is released, and the restricting portion 25 is constituted by the support portion 2. The fixed cam 29 is as shown in Fig. 4, the wheel 29 and the door stop 3, and all the recesses 41, 42, 51, q are not shown at the upper end, that is, the side stop 30 side and as shown in Fig. 5, and are fixed at the lower end. The door stop 30 has two convex portions 36 which are engageable with the concave portion 41 and the concave portion 41 72 of the fixed cam 29 as shown in Figs. 1 42 , 5 , 52 , 6 , and the γ cam 29 side. The restriction is made by the convex portion 3/phase-two 42' 5 bu 52, 61, 62, 7 b 72 rotation of the door stop 30. The following is for ^. 'Let the restricting portion 25 have a plurality of recesses 41, 42 72 for the knobs 52, 6b, 62, and 7 of the cymbal 17, and the plurality of recesses 41, 42 72 are provided in the insertion chain pin 4, 42, 52, m, (m), 51 , 52, 61 = the outer side of the hole in the diameter direction. The plurality of concave portions 1 62, 71, 72 face the circumferential direction portion 61 of the pin hole and the concave portion 62; and the same straight portion 71 and the concave portion 72 of the center portion of the concave portion 51 and the recess portion 51 are respectively deep on. The recesses 41, 42, 51, 52, 61, 62, 71 grip zt/i extending outward from the inner end portion in the diameter direction of the pin hole. The concave portion and the concave portion 42, the concave portion 51 and the concave portion, the concave portion 61 and the concave portion 仏 > m71 and the concave portion 72 are divided into two pairs of the convex portions of the (10) 3G. The two convex portions 36 of the door stop 30 are provided at the lower end of the rib portion 11 1361878 30379pif 3\, and the rib portion 37 is provided outside the cylindrical portion 33 in the diametrical direction and two convex portions. As shown in Fig. 5, P 36 is provided on both sides of the straight line passing through the center of the cylinder in the direction of the straight direction. In the case of the first embodiment, as shown in FIG. 4, the recessed portion 41 and the recessed portion 42 are provided corresponding to the fully closed position of the door 17. Further, the recess 51 and the recess 52 are provided corresponding to the fully open position, and the position corresponding to the door '7 1 ' is also (four) between the state position and the fully open position 61 and the recess 62, and the recess 71 and the recess 72. The recess 41 and the recess 42 engage with the projections 4 36 at the fully closed position of the door 17. The door 17 is maintained in a state in which the refrigerator compartment 12 is closed by the engagement of the hooks of the hinges 28, the claws 34, and the recesses 41 and the recesses. One. The concave portion 5i and the concave portion 52 of the crucible are at the open position of the door 17 = the convex portion 36 is engaged. When the door = force is applied by, for example, the door opening device 24, the door 17 will be rotated to the fully open position. At this time, it is set from the position after the full opening state of the maximum opening degree from the direction in which the convex portion 2 is rotated. For example, Η η rotates about convex =; two bits and sets, ; The opening angle of 17 is 9°. Position and convex heart: 5 12 1361878 3〇379pif When the refrigerator 10 is placed so that the right end is close to the wall of the house, the opening angle of the door 17 to the wall of the house can be prevented from being 90°. As described above, the recessed portion 61 and the recessed portion 62 are provided corresponding to a position at which the opening angle of the door 17 is not hindered from opening and closing, that is, the door 17 is rotated by 90° even when the refrigerator 1 is placed close to the wall of the house. The recess 71 and the recess 72 engage with the convex portion 36 of the door stop 30 at the half open position of the door 17. Specifically, the recess 71 and the recess 72 have an opening angle of 60 corresponding to the door 17. The position is engaged with the convex portion 36. For example, if the door 17 is opened 60°, the drink container can be taken out from the gantry 22 of the door 17 or placed on the gantry 22 even if the door 17 is not fully opened. As described above, the recessed portion 71 and the recessed portion 72 correspond to an opening angle at which the article can be taken out from the refrigerating chamber 12 or placed in the refrigerating chamber 12 without opening the door 17, that is, the position at which the door 17 is rotated by 60°. Settings. Next, the operation of the above-described restriction unit 25 will be described. Here, the case where the house wall is not provided close to the refrigerator 10 will be described as an example. • When the door opening operation unit 21 inputs a command to open the door, the door opening device 24 pushes the door 17 forward. That is, the door opening device 24 applies a force in the positive rotational direction to the door π. Thereby, the door 17 is rotated positively around the hinge 28, thereby opening the refrigerating compartment 12. At this time, the door opening device 24 applies a sufficient force to the door π. Therefore, the claw portion 34 of the door stop 30 provided on the door 17 is released from the engagement with the locking pin 32 of the hinge 28. At the same time, the convex portion 36 of the door stop 30 which is engaged with the concave portion 41 and the concave portion 42 of the fixed cam 29 will pass over the concave portion 41 and the concave portion 42. In addition, due to the door opening device 24 applying sufficient force to the door 17, 13 1361878 30379pif 71 72' ^. When the H 17 door 17 is rotated to the fully open position and the fixed cam 29 is stopped, the projection 36 of the door stop 3G engages with the recess 51 and the recess 52. By the convex portion 36, the opening device 24 is applied to the door 17: the force is relatively low: when the door 17 which is fully open is rotated by the recess 36 and the recess 61, 62 $, Can be fully closed. The ridges 61, 62, or the recesses 7 and 72 are engaged and restrained. Therefore, when the weight 5 is made, the convex portion 36 is engaged with each of the concave portions. Turning to the love department, its fine (four) money turns or reverses in the fully open state. The half and the second half are the state of the maintenance. In the case of the cows or the fully closed state, the above-mentioned _ 丨 丨 萄 , , , , , , , 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳 收纳The balance between the force of the ^pm^ plus the weight of the door 17, and the difference in the performance of the door opening device 24 by setting the restriction portion can be reversed even if the difference is caused by manufacturing differences or the like. The force is different, and the 卩17 can also be maintained in the open state. 1361878 30379pif A plurality of recesses 41, 42, 51, 52, 61, 62, 71, 72' are provided on the restricting portion 25 so that regardless of the weight of the door 17 or the force applied to the door 17 by the door opening device 24, The reverse rotation of the threshold is limited between the fully open position and the fully closed position. Therefore, the door 17 can be maintained in the open state in the fully open position or the half open position. The reverse rotation of the sill can be restricted by the engagement of the convex portion 36 provided on the door handle 30 with the concave portions 41, 42, 5, 52, 6b, 62, and 72 provided on the fixed cam 29. Therefore, the configuration of the restriction portion 25 is simplified. Therefore, the open state of the door 17 can be maintained without complicating the structure.

Hereinafter, a third embodiment of the present invention will be described based on the drawings. Fig. 8 is a front elevational view of the refrigerator of the present invention, and Fig. 9 is a front elevational view showing a state in which the refrigerating compartment door of the left and right split type is opened and the storage compartment door below is removed, and Fig. 10 is a longitudinal sectional view. The refrigerator main body 2〇1 formed of the outer box, the inner box, and the heat insulating box which is foamed and filled with the heat insulating material between the inner and outer boxes is provided with a refrigerating space at the uppermost portion as a storage space inside the inner box. In the chamber 202, the ice storage ice storage chamber 203 and the temperature switching chamber 2〇4 are arranged side by side through the heat insulating partition wall, and the cold beam chamber 205' is disposed in the lowermost portion. The front opening of the storage compartment is provided with a dedicated door to open and close the front opening of each storage compartment. 18 1361878 30379pif The refrigerating compartment 202 having the largest storage volume divides the room into a plurality of sections by a plurality of shelves 206, and the space below the space is a vegetable container in which a large capacity is accommodated as a space for storing vegetables. 2〇7, in front of the opening, the left and right doors 209 and 209 of the upper and lower ends of the two outer sides are pivotally supported by the hinges 208 and 208, respectively, and are independently mounted in the horizontal direction in a freely rotatable manner. . Frame-shaped magnetic gaskets 211 and 21 are attached to portions corresponding to the openings around the door inner sides 210 and 210' forming the back surfaces of the left and right doors 209 and 209', and when the left and right doors 209 and 209' have been closed. By the magnetic force of the magnet, the seals 211 and 21 are attracted to the peripheral portion 'of the opening of the refrigerating chamber 202, thereby hermetically sealing the inside and outside of the refrigerating chamber 202 to prevent heat leakage. In the central portion of the opening, a so-called French door type is used, that is, there are few longitudinal spacers for the two doors 209 and 20. 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 2〇2 or the vegetable container 2〇7 or placed in the shelf 206 in the refrigerating compartment 202 or in the vegetable container 2〇7, and taken out and stored. The bottle (pETb〇tde) or the seasoning in the storage rack 212 is stored and stored. The ice chamber 2 () 3 or the temperature switching chamber 204 and the cold beam chamber 2〇5 disposed in the lower portion of the refrigerating chamber 202 are provided inside the doors 203a, 204a, and 205a that are closed to the respective front openings, and Extending to the left and right sides of the living room 19 1361878 30379pif, the support frame (not shown), and the containers 203b, 204b, 205b placed on the support frame are provided by the support frame and the refrigerator. The sliding mechanism of the wall is drawn out to the outside of the box in the same direction as the respective doors. #上左右的Η 209, 209' The upper part of the upper surface of the ice-phase body 201 corresponding to the opposite end of the reverse hinge is provided with a door opening device 213, 213' respectively, which is formed by the user on the left and right doors, 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, which is shown in the longitudinal cross-sectional view of Fig. 11, the door opening device 213, 213' includes: winding a coil around the outer circumference of the cylindrical bobbin and molding it with a resin (m 〇 id) The solenoid is formed and a magnetic plunger 216 that sucks and moves the solenoid 215 in the axial direction. 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 2 (1). An ejector pin 219 is attached to the front end portion of the plunger 216 as a protruding member toward the door 2〇9, and 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 front end of the ejector pin 219 is protruded in the form of the back side of the door 209. A return spring 22〇 composed of a compression coil (6) spring is provided at the other end of the plunger Ή6, and is formed in a direction opposite to the direction in which the plunger π and the solenoid 215 are often protruded. After the energization of the screw 20 1361878 30379pif conduit 215 is stopped, the ejector pin 2i is again stored in the door opening device 213 by the return spring 22〇. Further, the door opening device 213' of the right door 2〇9 also has the same configuration as the door opening device 213. Further, the surfaces of the door opening devices 213, 213' disposed in the concave portion 218 are covered and protected by a unit cover 221 . Although not shown in the drawings, a door composed of a reed switch (substituting φ SWltCh) or the like is provided at a lower front portion of both sides in the refrigerating to 202 facing the back surface of each of the doors 2〇9 and 2〇9. The switch detects the opening and closing state of the doors 209, 209' by sensing the magnetic force of the magnetic cusps (11) (11') 211, 21 靠近 which are close to each other when the door is closed, and not only by detecting the opening and closing of the door. The rotation of the cooling fan in the control room, the indoor lighting, and the like are controlled, and when the door is opened, the door opening devices 213 and 213' that do not open the doors 209 and 209 are controlled to operate. Therefore, even if the touch switch 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, so that the ejector pin 219 can be prevented from being unexpectedly The door opening devices 213 and 213 are protruded to the space in front of the body, and the doors 209 and 209 can be operated under the condition that the doors 209 and 209 are closed. 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 213 213' is energized, and the plunger 216 will oppose The force of the return spring 220 is attracted and protrudes toward the door side, and the ejector pin 21 动作 operates in such a manner as to move forward as the plunger 216 moves so that its front end abuts against the corresponding door 209 or 209, After the back, its front end protrudes toward the front 21 1361878 30379pif and opens the door. 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 main body 201. The door holding mechanisms 222 and 222' are mechanisms 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' 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 upper surface of the refrigerator body 201 near the hinge 208' of the door 209' and including a sliding block 225 formed in the casing (housing) The guide groove 224 in the 223 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 is pivoted The 227 is pivotally supported, and is formed by the friction surface 229a of the sliding relationship of the side surface of the sliding block 225 by the coil spring 228 and the inclined end edge 229b. When the door opening device 213 is actuated to open the door 209, as shown in Fig. 14, the link 225 is connected to the front door 209 by the link 226. It moves and its front end corner is slidably engaged with the inclined end edge 229b of the brake block 229 to rotate the brake block 229 against the spring force of the spring 228. Further, when the door 2〇9 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. The resistance of the external force of the two directions in the direction of the door 209 or the direction in which the door 2 is opened, as long as the external force of the predetermined frictional force or more is not applied, the door 2〇9 is stopped at an arbitrary (four) angle. And maintains a stable state that does not move toward either the open side or either side of the 22 1361878 30379pif closing side. ^ Again, 'as the door holding device' is not limited to the above-described configuration 'can also be used for hunting A simpler configuration such as (torquehinge) allows the doors 209 and 209 to remain stationary at an arbitrary door opening angle.
如上所述，於大型冰箱中，形成於門内側210、210· 的多個收納架212的收納容積亦有擴大的傾向，由於將收 納架212的深度形成得較深，故而朝冷藏室2〇2内突出的 長度尺寸增大，從而冷藏室202内的擱板206或蔬菜容器 207的前端位置會相應地朝後方移動。其結果為當打開 門209或209而取放擱板206上的食品等時，如自上表面 觀，的概略圖即圖15所示’使用者A必須進一步靠近冷 藏室20^的開口部附近來將手插入至室内的深處的兩點鏈 線B所示的擱板206的前端位置。 —尤其蔬菜容器207是作為較大容量的寬度較寬的蔬菜 至而抽出自如地設置著’因此當抽出該蔬菜容器浙時，As described above, in the large-sized refrigerator, the storage volume of the plurality of storage racks 212 formed on the inner sides 210, 210· of the door tends to increase, and since the depth of the storage rack 212 is formed deep, the refrigerator compartment 2 is formed. The length of the inner protruding portion 2 is increased, so that the position of the front end of the shelf 206 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 from the top view, the user A must be closer to the opening of the refrigerator compartment 20^. The hand is inserted into the front end position of the shelf 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 relatively large-width vegetable having a relatively large width, so that when the vegetable container is taken out,

(2) The left and right doors 209 in the open state, the storage rack 212 of the office are in a state of being close to the body, and further, due to a large amount of food In the case where the door is severely weighted and turned in the closing direction, the chance of contact with the storage rack in the open state is increased, but only 23 1361878 30379pif constitutes the shelf 206 in the cold storage room 202. When the food is taken or placed, or when the doors 209 and 209' are opened when the vegetable container 207 is pulled out, the door 209 or 209' and both of the doors 209 or 209' can be stopped at an arbitrary opening angle. For example, the doors 209 and 209' can be stopped in the state of FIG. 15, and the doors 209 and 2091 can be kept in the stationary state as long as the user A does not move, so that it can be prevented from being stored in the storage rack 212 by food or the like. The weighted doors 209, 20 are less rotated in the closing direction. Therefore, 'there is no need to manually stop the rotation of the doors 209, 209 to be closed, so the user A can freely use both hands without hindering the pick-and-place operation by the storage rack 212, and will not come into contact when closing. The storage rack 212 of the doors 209, 209' stains the clothes or feels uncomfortable without coming into contact with the low temperature portion, so that the food picking and placing operation and the like can be conveniently performed. At this time, in order to make the doors 209, 209' rest at any door opening position, the door holding mechanisms 222, 222' have the braking force generated by the sliding block 225 and the brake block 229, so the force for opening the door is necessarily more normal. Increased, the increased opening force is supplemented by adjusting the force of the solenoid of the above-mentioned door opening devices 213, 213, thereby having a force to open the 209, 209 against the braking force. Thereby, the load of the user a can be reduced. In the above description, the case where both of the refrigerating compartments 202 of the right and left split type are used (fourth) is described as an example, and the door may be opened only by the left door or the right door 209, such as "two doors". The apparatus and the door holding mechanism can be applied to a storage compartment other than the rotary type. The same can be applied to a single 24 1361878 30379pif.
