Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a home delivery reception with a cooling device having a cooling chamber with three temperature zones.

(Prior Art) Conventionally, a home delivery method has been adopted in which frozen products, chilled products, or refrigerated products are housed in an insulating box having a cold source such as dry ice, and then delivered to each home.

(Problem to be solved by the invention) However, when the recipient is away, the item has to be taken back and delivered again, which is a hassle, and the insulating box is not suitable for each item. When the temperature has not reached the desired temperature, the freshness of the home-delivered products decreases due to being stored in the heat-insulating box for a long time.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a refrigerator with a cooling device that can keep frozen products, chilled products, or refrigerated products at an appropriate temperature, and can change the storage capacity of a refrigerated box. The purpose is to provide home delivery.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention includes a freezing box that is cooled to freezing temperature by a cooling device, an opening in the lower surface above the freezing box, and a cooling device that allows air to flow through the opening in the lower surface. a refrigerated box that can freely accommodate a frozen box; a chilled box that is cooled to a chilled temperature by a cold storage material that is disposed within the refrigerated box and cools the refrigerated box to a refrigerated temperature;
The invention is characterized by comprising a stopper mechanism for stopping the refrigerating box at different height positions on the outer surface of the peripheral side wall of the freezing box.

(Function) According to the present invention, there is provided a freezing box that is cooled to a cooling temperature by a cooling device, a refrigeration box that is cooled to a refrigeration temperature by a cold storage material, and a chilled box that is cooled to a chilled temperature by this cold storage material. This allows each type of home delivery product to be kept at an appropriate temperature.

In addition, since the freezer box can be freely stored inside the refrigerator box and can be fixed at multiple height positions using the stopper mechanism, the storage capacity of the refrigerator box can be changed by inserting the freezer box, and the amount of refrigerated products can be adjusted. It can be made into a corresponding accommodation space.

(Embodiment) Figures 1 to 5 show an embodiment of the present invention, in which 1 is a home delivery reception with a cooling device, and a refrigerated box 2, a frozen box 3, and a mechanical box 4 are arranged in order from above. There is.

The refrigerated box 2 has a heat insulating material 2 between an inner box 21 whose front and bottom surfaces are open and an outer box 22 that covers the inner box 21.

is the upper wall of the freezer box 2 and the open door 35 described later.
By moving the refrigerating box 2 downward, a freezing box 3 can be accommodated within the refrigerating box 2.

Further, a chilled box 5 is arranged on the upper surface of the inner box 21 within the refrigerated box 2. This chilled box 5 includes an inner box 51 with an open front side and an inner box 51
A cold storage material 53 is filled between the outer box 52 that covers the outer box 52, and an open door 55 is attached to the front opening 54. In addition, each of the boxes 51 and 52 is made of a metal with good heat conductivity, and the cool storage material 53 is made of a material mainly composed of chlorides such as ammonium chloride and calcium chloride, so that the latent heat temperature thereof is -5°C. The inside of the chilled box 5 is set to a chilled temperature of approximately 0.degree. C., and the temperature inside the refrigerated box 2, which has a larger storage space than the chilled box 5, is set to a refrigerated temperature of approximately 5.degree. Further, on the top surface of the outer box 52 of the chilled box 5, there is a refrigerated box 2.
Two cut grooves 27 extending back and forth are formed in the upper wall, and support rails 56 on the top surface of the chilled box 5 can be freely inserted into each cut groove 27, and the chilled box 5 can be detachably attached to the refrigerated box 2. There is.

The refrigerated box 3 has a heat insulating material 33 filled between an inner box 31 and an outer box 32 which have an open front side, and an opening/closing door 35 is attached to this front opening 34. A refrigerant pipe 41 serving as an evaporator is wound around the outer surface of the inner box 31, and a cooling device is constituted by this refrigerant pipe 41, a compressor 42, a condenser 43, etc. installed in the machine box 4, The inside of the freezer box 3 is set at a freezing temperature of approximately -20°C. Further, in the upper wall of the freezing box 3, a cut groove 36 for mounting a chilled box is formed similarly to the above-mentioned refrigeration box 2.

Reference numeral 6 denotes a stopper mechanism for the refrigerating box 2, which is vertically movable. As shown in FIG. 1, the stopper mechanism 6 has three locking pins 61 at predetermined intervals that are inserted into the lower end sides of the opposing side walls of the refrigerator box 2. The fitting holes 62 for each of the locking pins 61 are provided in a plurality of vertical stages. As shown in FIG. 4, each locking pin 61 has a large-diameter fitting portion 63 that fits into the fitting hole 62 at its tip, and a flange portion 64 that abuts the outer surface of the refrigerator box 2 at its rear end. is forming. In addition, a housing hole 65 for the fitting portion 63 is formed in the refrigerating box 2 at a portion facing the fitting hole 62, and a spring 66 is interposed in the housing hole 65 to urge the locking pin 61 toward the fitting hole 62 side. has been done.
The spring 66 causes the fitting part 63 to normally fit into the fitting hole 62 to connect the refrigerating box 2 and the freezing box 3, and when pulling the locking pin 61 toward the rear end, the fitting part 63 fits into the receiving hole 65. The refrigerated box 2 and the frozen box 3 are disconnected from each other. Further, the flange portions 64 of each locking pin 61 are connected by a connecting rod 67 for a handle.

Next, a method of using the delivery receiving unit 1 with a cooling device according to this embodiment will be explained.

First, in order to cool the cold storage material 53, the chilled box 5 is pulled out from the cut groove 27 of the refrigerated box 2 and taken out from the refrigerated box 2. Then, the support rail 56 is inserted into the cut groove 36 of the freezing box 3, and the chilled box 5 is placed inside the freezing box 3. Thereafter, the cooling device is activated to cool the cool storage material 53 to a latent heat temperature of −5° C. or lower. At this time, as shown in FIG. 5, there is a freezer box 3 in the refrigerator box 2.
When accommodating cold storage, the insulation effect inside the freezer box 3 is improved and the cold storage time is shortened.

Such a double structure has a connecting rod 67 that also serves as a handle.
By grasping and pulling outward, the fitting portions 63 of each locking pin 61 are disengaged from the fitting holes 62, and in this state, the refrigerating box 2 is moved onto the freezing box 3.

When the above-mentioned cooling of the cold storage material 53 is completed, the cold storage material 53 is pulled out from the freezing box 3 and installed into the cold storage box 2 again. As a result, the freezer box 3 is cooled by the cooling device, and the refrigerated box 2 and the chilled box 5 are cooled by the cold storage material 53, forming cold storage rooms having different temperatures. Therefore, regardless of whether the delivered product is a refrigerated product (chilled vegetables), a chilled product (e.g. fresh fish), or a frozen product (e.g. ice cream), each product must be stored at an appropriate cool temperature. can.

In addition, since the fitting holes 62 into which the locking pins 61 of the stopper mechanism 6 fit are provided in multiple stages vertically on each side wall of the freezer box 3, the height position of the refrigerator box 2 can be changed. The accommodation space of the refrigerated box 2 can be changed as desired, and the refrigeration temperature of the refrigerated box 2 can be changed by changing the storage space.

(Effects of the Invention) As explained above, according to the present invention, since there is a freezer box, a refrigerated box, and a chilled box each set to a freezing temperature, a refrigerating temperature, and a chilled temperature, products having different cold storage temperatures are suitably stored. It has the advantage of being able to be kept cold. In addition, since the refrigerated box can be freely stored within the refrigerated box and can be fixed at different height positions by the stopper mechanism, the storage capacity of the refrigerated box can be changed by inserting the frozen box.
It has the advantage that the storage space can correspond to the amount of refrigerated products, and that the refrigeration temperature in the refrigerated box can be changed by changing the storage space without changing the cold storage material.
