(Prior Art) In general, a vehicle heating refrigerator is known that includes an ice box for producing ice and a heating/refrigerating box for heating or cooling stored items.

The ice-making compartment and the hot/refrigerated compartment are each provided separately, and each has its own temperature controlled by an electronic refrigeration element.

On the other hand, in the hot refrigerator described in Japanese Patent Application Laid-open No. 61-285363, for example, when refrigerating, cold air from an automobile air conditioner is first introduced into the refrigerator, the air inside the refrigerator is replaced with cold air, and then electronic refrigeration is carried out. A configuration is disclosed in which the cooling capacity of the electronic refrigeration element is increased by cooling the electronic refrigeration element and cooling the heat dissipation part of the electronic refrigeration element with cold air from an air conditioner.

Additionally, vehicle refrigerators with ice-making compartments usually function as a heating compartment when the outside temperature is low, such as in the winter, and function as a refrigerator and ice-making compartment when the outside temperature is high, such as in the summer. .

(Problems to be Solved by the Invention) However, in recent years, there has been a demand for eating ice not only in the summer season but also in the winter season.

In such a case, the ice making compartment is cooled and the refrigerator is cooled or warmed, but ice cannot be made or warmed efficiently if the electronic refrigeration element alone is used to cool or warm the ice.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a refrigerator for vehicles that can efficiently make ice, warm and refrigerate ice even in winter.

(Means for Solving the Problems) A hot and cold refrigerator for a vehicle according to the present invention has a hot and cold storage box and an ice making box, and the hot and cold storage box has a first hot water/cooling switch that switches between introducing cold air and hot air.

It is characterized by being equipped with a switching means.

Further, in the introduction passage, a partition plate may be disposed in the center, and the first switching means may be switched between a position at both ends and an intermediate position.

(Function) According to the invention described in claim 1, even during heating operation such as in winter, the first cold/temperature switching means introduces cold air, and the second switching means introduces cold air into the second cold air passage. to cool the electronic refrigeration element for the ice-making compartment and increase its cooling efficiency.

On the other hand, when heating the inside of the hot/cold box, the first hot/cold switching means introduces hot air, and the second switching means introduces hot air into the first cold air passage to supply warm air to the hot/cold box. According to the invention as set forth in claim 2, the first hot water/cooling switching means is disposed at an intermediate position, the second switching means is disposed at an intermediate position, and hot air is blown into the first cold air passage. Then, cold air is blown into the second cold air passage to cool the ice-making electronic refrigeration element, thereby making it possible to perform warming and ice-making at the same time and improve their efficiency.
