Description

The present invention is a device for a mobile sales vehicle that does not require engine drive to cool a freezer and a freezer showcase by combining an electric refrigerating / cooling device that operates electrically and a refrigerating / cooling device that makes full use of solar power generation. is there.

In recent years, the aging of the population has been accelerating in Japan, but one of the social problems created by this is the so-called vulnerable shopping and shopping refugees, where it is difficult for the elderly and people living in remote areas to go shopping. Problems related to inconvenience have been talked about, and as one of the solutions support methods, the means of shopping for daily necessities using mobile sales vehicles is spreading nationwide.

The above-mentioned mobile sales vehicles are mainly medium-selling mobile sales vehicles in which a container for a mobile sales store is mounted on the loading platform of a truck, and shoppers get in the room to shop for products, and a container on the loading platform of the truck. Open the doors that open up and down or upward, which are called flip-up doors that are installed on both sides and the rear side or one of them, and the products displayed on the shelves in the loading platform are sold from outside the vehicle. There are many types of mobile sales vehicle types in operation.

In addition to daily necessities and room temperature products, frozen and refrigerated products are often sold in each of the above-mentioned mobile sales vehicles, and in order to maintain the temperature of these products, the mobile sales vehicles are equipped with freezer and freezing showcases. Either or both are installed.

In addition, the problem of global warming caused by the effects of greenhouse gases is now a global social problem based on the Paris Agreement as well as Japan, and Co2 exhaust accounts for a large proportion of this greenhouse gas emission. It is a commercial truck that emits gas, and the mobile sales vehicle in this case is not a little included in it. Furthermore, the freezers and freezer showcases of conventional mobile sales vehicles are cooled by an engine-directed refrigerator driven by the vehicle's engine, and in order to prevent product damage due to the temperature rise in the freezing room, from the time of loading to the end of sales. At present, it is difficult to stop the engine during this time period, and the annual emission of Co2 exhaust gas is considered to be enormous when converted on a global scale.

In addition, there have been some painful cases in which customers who are shopping are burned or hurt their throats due to smoke damage due to the high-temperature exhaust gas emitted from conventional mobile sales vehicles. In addition, there are not a few neighborhood troubles caused by vehicle noise on sale.

In order to solve these problems described above, a mobile sales vehicle that can completely stop the engine drive of the vehicle while the mobile sales vehicle is stopped is devised.

JP-A-2005-226918 JP-A-2005-55469 Actual opening 60-165787 Japanese Patent Application Laid-Open No. 6-135222 Japanese Patent Application Laid-Open No. 6-106964 Patent 2721501 Japanese Patent Application Laid-Open No. 2003-341415 Utility model registration No. 3123731

In order to avoid cooling by the engine direct connection type freezing and cooling method of the conventional mobile sales vehicle described above, there is a disclosure description of the operation of the refrigerator by solar power generation in Prior Art Documents 1 to 5 as reference prior art. However, in addition to the fact that none of them was devised to be installed in mobile sales vehicles, it is necessary to operate a refrigerator directly connected to the engine when solar power generation is difficult due to lack of sunshine, etc., and as a result, exhaust gas emission should be prevented. It is not possible, and it is insufficient in terms of concerns about greenhouse gas reduction and the impact on human health.

In addition to the above, there is a disclosure description of a cooling method using a cold storage material in Reference Prior Technology Documents Real Opening 60-165787 and Japanese Patent Application Laid-Open No. 2003-341415, but this technology is not a device for mobile sales vehicles, and neither of them is a cold storage. It is a means of using an engine-driven engine-directed refrigerator for freezing the material, and as a result, none of the prior arts is sufficient to solve the problem.

In addition to the above two items, there is a disclosure description of a cooling device with a private power generator installed in Utility Model Registration No. 3123731 of the Reference Prior Art Document, but even with this prior art, gasoline, light oil, etc. are used to drive the private power generator. Fuel is required, and as a result, exhaust gas is forced to be released. Therefore, there is a difference in the amount of exhaust gas between the private power generator and the operation of the refrigerator directly connected to the engine by driving the engine of the vehicle, but as a result, it is insufficient to solve the fundamental reduction of greenhouse gases.

Further, in addition to the above-mentioned three items, the description of all the prior art documents listed as references is insufficient for solving noise troubles with residents because the sound of the engine or the generator is eventually accompanied.
