Description

  The present invention relates to a distribution vehicle having a cold storage chamber for containing food and having a drain structure for discharging drain water such as defrost water and dew condensation water generated in an evaporator and a cold air duct.

  In a distribution vehicle equipped with a cold room, a drain pan and a drain tank are arranged below the cold air duct, and defrost water generated by the evaporator and condensed water adhering to the inner surface of the cold air duct are collected by the drain pan. After that, it is stored in the drain tank. In this type of distribution vehicle, a large number of cold air outlets are formed in the cold air duct facing the cold storage room, and when a tray is put into and out of the cold storage room, a part of the food enters from the cold air outlet and is placed on the drain pan. May fall. If the fallen food is left unattended, it will rot over time and give off a strange odor, or it will easily fall into an unsanitary state, such as mold growth. Moreover, there is a possibility that the drain pan is clogged by the dropped food.

  In order to solve such a situation, it is effective to disassemble the layout car in detail and periodically sterilize it, but it is difficult for the user of the service car to perform this kind of maintenance work. In most cases, it is necessary to entrust maintenance work to a full-time worker dispatched from the outside, which results in a lot of cost for hygiene management of the distribution car.

  With regard to the drain structure, in the arrangement vehicle of Patent Document 1, a drain outlet for discharging condensed water is opened on the bottom surface of the cold air duct, and the condensed water reaching the drain outlet is discharged to the drain tank through the drain pipe. . Furthermore, in order to easily clean the drain outlet and its surroundings, a small window is opened in the duct wall of the cold air duct facing the drain outlet, and a lid member for opening and closing the small window is attached to the window peripheral wall with a thumbscrew. It is concluded to. Further, in the arrangement vehicle of Patent Document 2, in order to prevent the condensed water from leaking from the small window, a soft plastic window frame member is attached to the small window, and the soft plastic lid member is further attached to the window frame member. Can be fitted and engaged.

  This type of drain structure is also disclosed in the allocation vehicle of Patent Document 3. There, a cooler (evaporator) is disposed in the machine room at the top of the main body, a tray portion is provided on the lower surface side of the cooler, and a drain pan and a drain outlet for receiving defrost water are disposed therein. The defrost water that has reached the drain outlet is discharged to the drain tank through the drain hose. Further, in order to clean the lower surface of the drain pan, the bottom wall of the saucer portion, and the like, an opening is formed in the bottom wall of the saucer, and the opening can be opened and closed with a slide cover. The slide cover is formed with a group of suction ports for ventilating air after circulating through the cold insulation chamber to the cooler side.

JP 2007-117319 A (paragraph number 0019, FIG. 1) JP 2008-267756 A (paragraph number 0025, FIG. 1) Japanese Patent No. 4206316 (paragraph number 0021, FIG. 5)

  According to the drain structure of Patent Document 1, when the four thumbscrews are loosened and the lid member is removed, the small window can be opened, and the drainage port and its surroundings are cleaned from the side of the small window, so that the hygiene around the drainage port is obtained. The state can be optimized. Similarly, also in the drain structure of patent document 2, the surroundings of a drain outlet can be cleaned and made into a sanitary state by removing the cover member press-fitted to the small window. However, in any case, since the opening area of the small window is small, even if cleaning is performed using, for example, a cleaning brush, the cleaning range is limited to the periphery of the drain port, and the bottom surface of the cold air duct is extensively cleaned. It cannot be done, and foreign matter tends to accumulate. In addition, since the lid member can be freely removed from the small window as needed, the lid member can be frequently washed and dried, but on the other hand, the dried lid member may be forgotten to be attached to the small window. In some cases, a large amount of cold air may flow out of the small window, making it impossible to properly circulate the cold air. Furthermore, there is a risk that defrosted water or condensed water falling in the cold air duct will jump from the drain pan and jump into the cool room from the small window, causing the food to be contaminated.

  According to the drain structure of patent document 3, the lower surface of a saucer part can be open | released by removing a slide cover, and the lower surface of a drain pan and the bottom wall of a saucer part can be cleaned. However, because the slide cover is placed facing the uppermost tray holder, when condensation occurs on the lower surface of the drain pan, the condensed water dripping from the drain pan falls from the suction port of the slide cover or the periphery of the cover. The food may be contaminated and there is a problem in food hygiene. Incidentally, the cooler is operated until just before the start of the catering, and the power is cut off at the start of the catering. Therefore, the dew condensation water adhering to the fins of the cooler is dripped at the time of the arrangement, or the frost is liquefied and easily dropped. In addition, since the drain pan immediately after the cooler is stopped is easily cooled down by defrost water or dew condensation water, under high temperature and humidity seasonal conditions, air that contains a lot of water vapor as the tray is put in and out. Easy to enter the cold room. For this reason, the air sucked from the suction port cannot be prevented from condensing on the lower surface of the drain pan, and the food is likely to be soiled by the dew condensation water dripped from the drain pan.

An object of the present invention is to provide a distribution vehicle capable of maintaining a drain pan and its peripheral structure in a sanitary state by allowing a drain pan provided in a cold air duct to be cleaned more accurately and easily.
Although the object of the present invention is to allow the window cover to open and close the cleaning window provided in the cold air duct, it is possible to eliminate the forgetting to attach the window cover by restricting the removal of the window cover during normal cleaning. The object is to provide a service car that can always circulate cold air properly.

  The distribution vehicle according to the present invention includes a cooling unit, a storage chamber 13 including a cold storage chamber 14, a cool air duct 12 disposed along the cold storage chamber 14, and a drain structure for discharging drain water. The cool air generated by the cooling unit is guided by the cool air duct 12 and blown out to the cold insulation chamber 14. Inside the cold storage chamber 14, partition units including the tray receivers 31 are arranged in a multistage manner, and a tray accommodating space S is provided above each tray receiver 31. A drain pan 59 and a drain port 60 for receiving drain water are provided on the inner bottom of the blow-out passage 46 partitioned inside the cold air duct 12. A cleaning window 66 and a window cover 67 that opens and closes the window 66 are provided on the duct wall of the outlet passage 46 facing the lowermost tray accommodating space S. The window cover 67 can slide open and close to a lower closing position for closing the cleaning window 66 and an upper opening position for opening the cleaning window 66. The drain pan 59 and the drain outlet 60 are cleaned in a state where the window cover 67 is slid to open the cleaning window 66.

  The window cover 67 is slidably guided by a pair of guide bodies 70 provided on the duct wall of the outlet passage 46. A stopper 73 that receives the window cover 67 that has been slid to the open position and restricts the window cover 67 from being separated from the guide body 70 is provided on the inner wall of the storage chamber 13.

  The partition unit includes a partition body 30 that divides the interior of the storage chamber 13 into a cold storage chamber 15 and a cold storage chamber 14, and a tray receiver 31 that is connected to both sides of the storage chamber 13 and divides the interior of the storage chamber 13 up and down. The side end of the tray receiver 31 is fixedly supported by a connecting metal fitting 43 fixed to the inner wall of the storage chamber 13. The lower end surface of the second connecting wall 37 provided on the tray receiver 31 also serves as a stopper 73.

  The cleaning window 66 is open from the front end toward the rear end of the passage width in the front-rear direction of the blowing passage 46.

  In the allocation vehicle according to the present invention, a drain pan 59 and a drain port 60 are provided on the inner bottom of the blowout passage 46 provided in the cold air duct 12, and the duct wall of the blowout passage 46 facing the lowermost tray storage space S is provided. The window cover 67 that opens and closes the cleaning window 66 and the window 66 is provided. According to such a distribution vehicle, the cleaning window 66 can be opened at a position close to the drain pan 59 by sliding the window cover 67 to open the cleaning window 66. In addition, the drain pan 59 and the drain outlet 60 are cleaned with a cleaning tool such as a brush inserted from the cleaning window 66 to accurately and easily remove food residues and dust adhering to the drain pan 59 and the drain outlet 60. Can be washed away. Therefore, according to the distribution vehicle according to the present invention, the drain pan 59 and the drain port 60 provided on the inner bottom of the outlet passage 46 can be cleaned more accurately and simply by the user himself / herself, and the drain pan 59 and its surrounding structure can be obtained. Can always be kept in a hygienic state.

  When the stopper 73 is provided on the inner wall of the storage chamber 13 and the window cover 67 slid to the open position is received by the stopper 73, the window cover 67 is slid beyond the open position, and the guide body 70 Separation can be controlled. In this way, the opening operation of the window cover 67 is restricted for the following reason. If the window cover 67 that has been slid to the open position can be completely removed from the guide body 70, the user can easily clean and dry the window cover 67. However, the window cover 67 that has been cleaned and dried may be forgotten to be assembled to the guide body 70. If the cooling unit is operated in this state, most of the cold air supplied to the blow-out passage 46 is discharged from the cleaning window 66. It flows out and stays in the lower part of the cold storage chamber 14, and it becomes impossible to circulate cold air appropriately. In order to prevent such fatal misuse, the window cover 67 slid to the open position is restricted from being separated from the guide body 70. This is also advantageous in that there is no room for the window cover 67 to be lost.

  If the lower end surface of the second connecting wall 37 of the tray receiver 31 also serves as the stopper 73, the opening operation of the window cover 67 can be regulated without the need for providing a dedicated part functioning as a stopper, so the cost can be reduced accordingly. . Further, since the window cover 67 is received using the tray receiver 31 fixed and supported by the connecting metal fitting 43 and having high positional accuracy in the height direction, the window cover 67 and the guide body 70 in a state in which the window cover 67 is opened. Therefore, the closing operation of the window cover 67 can be performed smoothly.

  If the cleaning window 66 is opened from the front end toward the rear end of the passage width in the front-rear direction of the blow-out passage 46, the opening dimension in the front-rear direction can be increased to the limit, so that the drain pan 59 facing the cleaning window 66 is reached. Can be cleaned all over.

  A drain structure is provided from the machine room 3 to the lower surface of the carriage 2 in order to discharge drain water such as defrost water and dew condensation water generated with the operation of the cooling unit. In FIG. 5, the drain structure includes a drain concave portion 57 provided on the upper surface of the heat insulating box 25, an upper drain hose 58 that guides the drain water collected in the drain concave portion 57, and a drain pan provided on the inner bottom of the outlet passage 46. 59, a lower drain hose 61 that guides the drain water collected by the drain pan 59 from the drain port 60, and a drain tank 62 (see FIG. 2). The upper drain hose 58 is led out from the drain hole 63 of the drain recess 57 and is suspended along the hose passage 50. The lower end position of the upper drain hose 58 is positioned slightly above the upper edge of the cleaning window 66 described later.

  Thus, when the upper drain hose 58 is arranged in the hose passage 50 divided by the passage frame 48, the defrost water mainly discharged by the upper drain hose 58 is isolated from the cold air passing through the blowout passage 46, It is possible to prevent the defrost water from being blown into the tray housing space S together with the cold air. In addition, since the upper drain hose 58 is positioned directly above the drain port 60, the defrost water flowing down from the upper drain hose 58 can be quickly collected in the drain tank 62 via the lower drain hose 61. The drain pan 59 collects defrosted water that has flowed down from the upper drain hose 58 and condensed water that drip along the inner surface of the blow-out passage 46 and causes it to flow down from the drain port 60.

  A cleaning window 66 and a window cover 67 for slidingly opening and closing the window 66 are provided on the duct wall of the blowout passage 46 facing the lowermost tray accommodating space S on the cold storage chamber 14 side so that the drain pan 59 can be cleaned. As shown in FIGS. 1, 8, and 9, the cleaning window 66 is opened on the lower half side of the duct wall between the lowermost second connection wall 37 and the second second connection wall 37. 1 is opened only on the duct wall facing the cold insulation chamber 14 on the left side as viewed in FIG. In order to easily clean the drain pan 59, the cleaning window 66 is greatly opened from the front end toward the rear end of the passage width in the front-rear direction of the blowing passage 46. The window cover 67 is formed of a stainless steel plate, and integrally includes a long and narrow rectangular main body 68 and an operation unit 69 bent at a right angle along the upper edge of the main body 68. A pair of guide bodies 70 are fixed to the peripheral walls of the opening front and rear of the cleaning window 66. The front and rear edges of the main body 68 are guided and supported by the guide body 70 so as to be slidable in the vertical direction. The window cover 67 can be slid open and closed between a lower closing position closed at 68 and an upper opening position where the cleaning window 66 is opened.

  If the window cover 67 slid to the open position can be completely removed from the guide body 70, the user can easily clean and dry the window cover 67. However, the window cover 67 that has been cleaned and dried may be forgotten to be assembled on the guide body 70. If the cooling unit is operated in this state, most of the cold air supplied to the blow-out passage 46 is removed from the cleaning window. Since it flows out of 66 and stays in the lower part of the cold insulation chamber 14, it becomes impossible to circulate cold air appropriately. In order to prevent such fatal misuse, the window cover 67 slid to the open position is restricted from being separated from the guide body 70.

  Specifically, as shown in FIG. 1, the operation of the window cover 67 slid to the open position using the lower end surface of the second connection wall 37 provided on the tray receiver 31 in the second stage from the bottom as a stopper 73. By receiving the portion 69 with the stopper 73, the window cover 67 is restricted from being further slid to the open side. The lower portions of the front and rear edges of the main body 68 in this state are engaged with the upper portion of the guide body 70. According to such a window structure, although the cleaning window 66 provided in the cold air duct 12 can be opened and closed by the window cover 67, the removal of the window cover 67 is restricted during normal cleaning, and the user forgets to attach the window cover 67. Since it can be eliminated, it is possible to always properly circulate the cold air in the cold insulation chamber 14. The window cover 67 that has been slid to the open position can be held in an open position by friction between the main body 68 and the guide body 70 by slightly tilting the main body 68 forward or backward. 67 does not return to the closed position due to its own weight.

  According to the arrangement vehicle configured as described above, the cleaning window 66 can be opened at a position close to the drain pan 59 by pinching the operation portion 69 and sliding the window cover 67 upward, so that the drain pan 59 and the drain port 60 can be cleaned by the user himself and kept hygienic. For example, with a brush inserted from the cleaning window 66, food residues and dust adhering to the drain pan 59 and the drain port 60 can be washed out accurately and simply. At this time, since the cleaning window 66 is greatly opened from the front end to the rear end of the passage width in the front-rear direction of the blow-out passage 46, the drain pan 59 facing the cleaning window 66 is thoroughly cleaned to the drain pan. 59 and its surrounding structure can always be kept in a hygienic state. After the cleaning, when the window cover 67 is slid downward and returned to the closed position, the cleaning window 66 is completely blocked by the main body 68, so that the dew condensation water that falls on the cold air duct 12 or the upper drain hose 58 is removed. It is possible to reliably prevent the drain water flowing down from the water from splashing at the drain pan 59 and jumping from the cleaning window 66 into the cold insulation chamber 14. Therefore, it is possible to reliably prevent the food stored in the cold insulation chamber 14 from being contaminated by defrosted water or condensed water.

  In the above-described embodiment, the case where the inside of the left and right storage chambers 13 is divided into the cold insulation chamber 14 and the thermal insulation chamber 15 by the partition unit has been described. However, the storage chamber 13 includes the cold insulation chamber 14. If it is, it is enough. Moreover, since the arrangement | positioning relationship before and behind the blowing passage 46 and the suction passage 47 in the cold air duct 12 can be set freely, it is not limited to the arrangement structure of the passage demonstrated in the Example. The cleaning window 66 may be opened and closed by a plurality of window covers 67. The stopper 73 can be provided on the inner wall of the storage chamber 13 such as the duct wall of the cold air duct 12 in addition to the tray receiver 31. For example, the window cover 67 is formed of a stainless steel material that can be magnetically attracted, a magnet (stopper 73) is disposed on the duct wall, and the window cover 67 that is slid to the open position is attracted by the magnet and held in the open posture. Can do. In the above embodiment, the upper drain hose 58 is disposed in the hose passage 50. However, since the hose passage 50 is separated from the outlet passage 46 by the passage frame 48, the upper drain hose 58 may be omitted. it can.
