Description

  The present invention relates to a food processing apparatus configured to be capable of storing a cart on which a food tray is placed and performing a cooling process or a heating process on food on the cart, and in particular, a state where the cart is not stored in a warehouse. The present invention relates to a technique for preventing a cold air leak or a warm air leak from the inside when performing a pre-cooling operation or a pre-heating operation.

  Food processing apparatuses that perform cooling processing or heat processing on food are known. For example, a device that performs rough heat removal, quick cooling, or quick freezing on food stored in a warehouse is “blast chiller” or It is widely known as “Shock Freezer”. In addition, some food processing apparatuses of this type can receive a cart on which a food tray is placed in a cabinet and perform a cooling process or the like for each cart.

  For example, the refrigerator described in Patent Literature 1 opens and closes a refrigerator main body having a storage chamber made of a heat insulating box with a front opening, a cooling unit for supplying cold air toward the storage chamber, and a front opening of the storage chamber. The cooler body is supported at an upper position spaced apart from the floor surface by four legs disposed on the bottom surface thereof. The cart on which the food tray is placed is provided between a trolley configured to be movable by a caster, a base provided above the trolley, a pair of front and rear frames provided on the base, and the frames. And a multi-stage tray receiver. The support portion that supports the base is composed of a pair of left and right support columns that are erected on the front edge of the carriage, and a metal support plate that is fixed between the support columns. It projects in a cantilevered manner toward the rear.

  In a refrigerator that performs a cooling process for each cart as in Patent Document 1, a cart loading portion for receiving a cart is formed between the bottom wall of the storage chamber and the inner surface of the door. Specifically, in the refrigerator of Patent Document 1, the front edge portion of the bottom wall of the storage chamber is located behind the left and right side walls of the storage chamber and the front edge portion of the top wall, and the bottom portion of the storage chamber Is formed with a recess having no bottom wall. When the cart is pushed into the storage room, the carriage is located below the bottom wall, the base is located above the bottom wall, and the support pillar is received in the recessed portion, so that the entire cart is cooled. It is designed to be stored in the body. Further, the storage room side door can be closed in the storage state in which the entire cart is stored in the refrigerator. In addition, when the cart is stored in the refrigerator main body, the cart side support plate is received by the cart receiver provided at the front edge of the bottom wall of the storage chamber, and the support plate is provided on the cart receiver. The recessed portion is closed by pressing the cart packing. That is, when the cart is stored in the storage, the recessed portion of the storage is closed with the support plate, so that the cold air leaks from the interior through the recessed portion or the outside air through the recessed portion. Can be prevented from entering.

  In the refrigerator described in Patent Document 1 as described above, when the cart is stored in the storage, the recessed portion of the storage is closed by the support plate on the cart side, and the inside of the storage via the recessed portion is removed. However, when the cart is not stored, the recessed portion cannot be closed. For this reason, when the pre-cooling operation is performed before the cart is stored, it is inevitable that the cold air leaks from the inside of the warehouse through the recessed portion and the thermal efficiency of the cooling room is lowered.

  On the other hand, in the storage described in Patent Document 2, a pair of left and right notches are provided at positions opposite to a pair of left and right columns (support pillars in Patent Document 1) of the cart on the bottom wall of the storage room, and each notch is provided. Covering with a covering member prevents cold air leakage when the cart is not stored. The covering member is configured to be movable in the front-rear direction in the notch, and is urged forward by the elastic body, and when the cart is stored in the warehouse, it is pushed by the support and moves backward. When the cart is pulled out from the interior, it is configured to move forward by receiving the biasing force of the elastic body.

  According to the storage described in the cited document 2 configured as described above, the notch is closed by the support column when the cart is stored, and the notch is closed by the covering member when the cart is not stored. Even when the cart is not stored, it is possible to reliably prevent the leakage of cold air from the notch, and therefore prevent cold air leakage or warm air leakage from the interior during pre-cooling operation or pre-heating operation. Can do.

Japanese Unexamined Patent Publication No. 2014-2115019 JP-A-5-317127

  In the storage described in Patent Document 2, since the covering member is pushed in by the support column, when the cart is stored in the storage, it is troublesome to accurately align the support column on the cart side with the covering member on the storage chamber side. Work is necessary, and it is difficult to push the cart into the cabinet with good work efficiency and proceed with the cooling process. In addition, in order to store the cart in the warehouse, it is necessary that the lateral width of the notch on the storage room side and the lateral width of the support column on the cart side coincide with each other. However, there is a disadvantage in that it is limited to a kind of cart and inferior in versatility.

  The object of the present invention is to solve the problems of the conventional food processing apparatus as described above, and cold air leakage and warm air leakage from the inside of the cabinet occur even when the cart is not stored. It is possible to suppress a decrease in thermal efficiency during pre-cooling operation or pre-heating operation, and it can be widely applied to various carts regardless of the distance between the cart struts. An object of the present invention is to provide a food processing apparatus that is excellent in work efficiency by minimizing cart positioning.

The upper region of the horizontal wall 15 sandwiched between 16 is a loading port 52 of the cart loading unit 50, and a packing 19 is provided on the front side of the horizontal wall 15 and the left and right vertical walls 16 so as to surround the loading port 52. When the front door 11 is closed when the cart is not stored, the rear surface of the shutter 61 comes into close contact with the packing 19 provided on the flange wall 18 so that the gap between the shutter 61 and the flange wall 18 is closed. Can be removed.

  The support portion 43 of the cart 40 is provided with a closing body 48 that closes the loading port 52 in the cart storage state in which the cart 40 is stored in the apparatus main body 2. Each of the upper ends of the vertical walls 16 of the walls 18 is provided with packings 34 and 22, and when the front door 11 is closed in the cart storage state, the closing body 48 is connected to the packing 34 at the lower end of the front door 11. The closure body 48 is sandwiched between the upper end packing 22 of the vertical wall 16 of the flange wall 18 and can be configured to be pressed against the rear.

  In the present invention, a cart loading portion 50 including a loading gap 51 for receiving the support portion 43 of the cart 40 and a loading port 52 for receiving the base portion 44 of the cart 40 is provided at the lower front end of the apparatus main body 2. The upper half portion of the cart 40 having the base portion 44 and the tray receiver 46 is stored in the storage chamber 5 of the apparatus main body 2. In addition, when the cart 40 is not stored in the apparatus main body 2, the loading port 52 is closed by the shutter 61 of the shutter mechanism 60 provided on the back side of the front door 11 of the apparatus main body 2. According to the food processing apparatus of the present invention in which the shutter mechanism 60 is provided on the back surface side of the front door 11 as described above, the loading port 52 can be blocked by the shutter 61 of the shutter mechanism 60 when the cart is not stored. Therefore, even when the pre-cooling operation or the pre-heating operation is performed in a state where the cart 40 is not stored, it is possible to reliably prevent cold air leakage, warm air leakage, or outside air inflow from the loading port 52. As mentioned above, according to this invention, it can suppress that the thermal efficiency in the storage chamber 5 falls at the time of pre-cooling operation or pre-heating operation, and can obtain the food processing apparatus excellent in energy efficiency at the time of pre-cooling operation or pre-heating operation. it can.

  In addition, according to the present invention, it is possible to eliminate the strict alignment work such as the alignment work for the notch of the support column when the cart is stored in the apparatus main body as in the conventional apparatus (Patent Document 2). Therefore, the cart 40 can be stored in the apparatus main body 2 more quickly, and a food processing apparatus that is much more convenient than the conventional apparatus (see Patent Document 2) can be obtained. In addition, according to the present invention, the cart 40 that can be stored in the apparatus main body 2 has a horizontal width of the notch on the side of the storage chamber and a horizontal direction of the column as in the conventional apparatus (see Patent Document 2). It is not limited to a kind of cart with the same interval width, and even various carts with different interval widths can be stored. Can be obtained.

  The shutter 61 is configured such that the shutter mechanism 60 can be moved back and forth between an open posture closer to the front and a closed posture closer to the rear, and a biasing means 62 that biases the shutter 61 toward the closed posture. When the front door 11 is closed, the shutter 61 is maintained in the closed posture by the urging means 62 when the cart 11 is not stored, so that the loading port 52 is closed by the shutter 61. When the front door 11 is closed in the cart storage state, the rear surface of the shutter 61 comes into contact with the front end portion of the cart 40, and the shutter 61 is displaced from the closed position to the open position against the urging force of the urging means 62. Such a configuration can be adopted. According to this, by closing the front door 11, the shutter 61 is closed when the cart is not stored, and the loading port 52 can be automatically closed with the shutter. Therefore, according to the present invention, the closing operation of the loading port 52 by the shutter 61 can be easily performed without performing a special operation.

  When the biasing means 62 is constituted by a torsion spring including a torsion coil-shaped spring body 71 and a pair of spring arms 72a and 72b extending from both ends of the spring body 71, a shutter including the biasing means 62 is provided. The occupied area of the mechanism 60 can be minimized.

  When the front door 11 is closed when the cart is not stored, the rear surface of the shutter 61 comes into close contact with the packing 19 provided on the flange wall 18, thereby closing the gap between the shutter 61 and the flange wall 18. Thus, it is possible to reliably prevent external air and cool air in the storage chamber from entering and exiting through the loading port 52 in a cart unstored state.

  When the front door 11 is closed in the cart storage state, the closing body 48 on the cart 40 side is sandwiched between the packing 34 at the lower end of the front door 11 and the packing 22 at the upper end of the vertical wall 16 of the flange wall 18. When the closing body 48 is configured to be pressed toward the rear, the front door 11 is simply closed, and no special operation is performed between the closing body 48 and the front door 11. Since the gap or the gap between the closing body 48 and the flange wall 18 can be closed, it is ensured that external air and air inside the storage chamber 5 enter and exit through the loading port 52 in the cart storage state. Can be prevented. Further, by simply closing the front door 11, the cart 40 can be moved to the storage position via the closing body 48, and the closing body 48 can be pressed against the packing 19 of the flange wall 18. Thus, the closing operation of the loading port 52 by the closing body 48 can be easily performed.

In such precooling operation, the cart 40 is not accommodated in the refrigerator main body 2, and the loading port 52 of the loading unit 50 is closed by a shutter 61 provided in the right door 11. Therefore, the inside of the storage chamber 5 can be efficiently cooled to a predetermined temperature. That is, as shown in FIG. 5, when the right door 11 is closed when the cart 40 is not stored in the refrigerator main body 2, the shutter 61 in the closed position of the front is moved to the periphery of the loading port 52. Since it can be brought into pressure contact with the packing 19, the loading port 52 can be closed by the shutter 61. As described above, airtightness in the storage chamber 5 is ensured, and cold air leaks out from the loading port 52 or outside air enters from the loading port 52 into the chamber. Can be pre-cooled.

  When the pre-cooling operation is completed, the right door 11 is opened, and the cart 40 on which the food is placed on the tray 47 is pushed from the front opening 10 into the storage chamber 5. At this time, the cart 40 can be pushed into the storage chamber 5 in an appropriate posture by moving the carriage section 42 along the guide body 55. When the cart 40 is further pushed into the storage chamber 5, the base portion 44 inserted from the loading port 52 is positioned above the bottom wall 5 a of the storage chamber 5, and between the bottom wall 5 a of the storage chamber 5 and the floor surface F. The carriage portion 42 is positioned at the same time, and the support portion 43 is received in the loading gap 51 so that the upper half of the cart 40 having the base portion 44 and the tray receiver 46 can be stored in the storage chamber 5.

  As described above, when the right door 11 is closed in the state where the cart 40 is stored in the refrigerator main body 2, the closing plate 48 of the cart 40 is brought into pressure contact with the packing 19 on the periphery of the loading port 52, and the loading port 52 can be closed by the closing plate 48. More specifically, as shown in FIG. 4, when the right door 11 is closed, the support pillars 43a and 43a are pushed forward by the shutter 61, and the closing plate 48 is pushed forward by the lower door side packing 34. Thus, the closing plate 48 can be pressed against the packing 19 on the periphery of the loading port 52 to close the loading port 52. At this time, the lower side door packing 34 is brought into contact with the upper side packing 22 of the vertical wall 16 of the flange wall 18 and the front surface of the upper edge of the closing plate 48, so Airtightness can be ensured. Further, as described above, when the right door 11 is closed while the cart 40 is stored in the refrigerator main body 2, the shutter 61 is closed against the urging force of the torsion spring as the urging means 63. Since the posture (FIG. 5) is displaced to the open posture (FIG. 4), the right door 11 can be closed without hindrance.

  FIG. 9 shows another embodiment of the shutter mechanism 60, in which a pair of left and right link mechanisms composed of a pair of upper and lower link arms 62 and 62 is a cross link mechanism instead of a parallel link mechanism. This is different from the first embodiment. That is, in this other embodiment, the center portion in the length direction of the pair of upper and lower link arms 62 and 62 is connected in an X shape by the pivot shaft 80 to constitute a cross link mechanism. The lower bearing wall 81 fixed to the front panel 26 of the right door 11 and the side wall 82 provided on the lower side of the shutter 61 are elongated holes 83 and 84 that allow the connecting shafts 64 and 65 to move up and down. The connecting shaft 64 moves along the elongated hole 83 and the connecting shaft 65 moves along the elongated hole 84 as the shutter 61 opens and closes. A biasing force of a torsion spring as a biasing means 63 acts on the link arm 62 whose base end side is fixed to the inner surface of the front panel 26 and located on the upper side, and the shutter 61 causes the link 61 in FIG. It is urged to be in the closed position as shown. The other points are the same as in the first embodiment.

  In the said Example, the food processing apparatus which concerns on this invention is not restricted to a quick-cooling warehouse, It can apply also to the heating chamber etc. which further heat-process with respect to foodstuffs.
