Description

  The present invention relates to a storehouse for storing foodstuffs and a trolley equipped with the storehouse.

  For example, in a hospital or the like, a distribution car is used to carry meals from the kitchen to each room. Active hygiene management is required because it carries meals that patients eat. Needless to say, sanitary management must be more thoroughly performed, especially in an environment where there are many strong bacteria having drug resistance, such as in hospitals.

  In response to such a request, Patent Document 1 proposes a distribution car that circulates sterilizing air such as ozone in a state in which a heat storage provided in the distribution car and a partition plate of the refrigerator are opened. The trolley is designed to sterilize after finishing the laying, and when the door is opened, sterilization is stopped so that sterilization considering the safety to workers and food is possible. Yes.

  Moreover, in patent document 2, it has the tank which accommodates disinfectant, and the spray nozzle for several disinfectant spraying attached to the suitable place in a warehouse and / or the vicinity of a wheel, Disinfectant, such as sodium hypochlorite There has been proposed a garage car that sprays. The service vehicle can be sterilized simply and reliably by shortening the sterilization time and removing differences between workers in the sterilization work.

Further, in Patent Document 3, by installing an ozone generating element in a ventilation unit of a warm storage and making it detachable, it is possible to improve the life of the ozone generating element and achieve a reduction in size and price while maintaining the temperature. A barge that can deodorize and sterilize the warehouse is proposed.

  However, hygiene management is also important before and after the catering, that is, when dishes and meals are not delivered in the car, but all meals are finished during the catering, that is, after the dishes and meals are placed in the catering garage. It goes without saying that hygiene management is the most important thing.

  In other words, every time the caterer stops and opens the door and takes out the dish tray, the food and dishes are exposed to germs floating in the hospital air. Especially in the case of use in hospitals, in addition to the fact that there are a lot of various fungi, the transport route of filth and the transport route of the distribution car overlap, or the patient himself / herself takes out food from the warehouse, etc. The risk of contact between food and bacteria increases.

  In addition, when the door is opened, the temperature of the warm storage (refrigerator) is low (high) and may reach a dangerous temperature range where bacteria can grow and proliferate. The recommended storage temperature range is 65 ° C. or more for the temperature storage, 5 ° C. or less for the refrigerator, and 10 to 60 ° C. is a dangerous temperature. If the door of the trolley is open for a long time, or depending on the patient, the set temperature in the warm storage room may be lowered so that the tableware can be properly held, or if the patient delays the meal time during the examination, etc. There has been a problem that the risk of being left in the dangerous temperature range becomes higher.

  However, the arrangement vehicles of Patent Document 1 and Patent Document 2 described above are premised on hygiene management after the end of the arrangement, that is, before and after the arrangement, and do not correspond to the hygiene management during the arrangement. On the other hand, the distribution vehicle of Patent Document 3 can be applied during the distribution, but since ozone is generated to deodorize and sterilize, there is a problem that ozone is highly toxic and has a higher concentration. In other words, due to the unstable nature of ozone, it disappears immediately in the atmosphere, so there is no persistence, but in some cases it takes several hours to several tens of minutes to complete extinction. There may be problems with the surface. Moreover, there is a concern that the life of the garage garage may be shortened due to deterioration of the materials of the garage and tableware by repeatedly exposing the inside of the garage garage to high-concentration ozone at high temperatures.
