Next, a home delivery service method using the home delivery cool box 1 will be described together with the operation of the home delivery cool box 1. A courier for foodstuffs or the like is often absent during the delivery time, and therefore the courier cool box 1 is preliminarily provided to the customer (delivery destination of the courier) of the customer who has difficulty in receiving the courier directly. Have been installed. At the time of installation, a dedicated stand (fixed type or wall mounted type) is used to fix the home delivery cool box 1 to an appropriate place such as the front door of the house, and the power cord is connected to the outlet. I'll do it. In addition, the customer can individually lock and unlock the lock device of the home delivery cold storage box 1 installed at the customer's customer (unless the home delivery cold storage box 1 installed at another customer is unlocked. I can't do that). On the other hand, each home delivery cool box 1 installed at each of a plurality of customers
A master key that can be locked and unlocked is manufactured in common with one lock device, and this master key is stored by the courier.

Then, the courier who receives the product order from each customer via communication means such as a telephone, a facsimile, the Internet (e-mail), etc., installs the courier according to each order in at least the area covered by the courier. A delivery person possesses a master key capable of locking and unlocking all the delivered cool boxes 1 for delivery, and directs them to delivery. The courier visits a plurality of customers one after another and delivers the home delivery according to the order from each customer. At this time, when the customer is absent and cannot deliver the home delivery, the lock device of the home delivery cool box 1 installed at the customer is unlocked with the master key, the lid 3 is opened, and the home delivery is accommodated. It is accommodated in the space 4. Here, frozen foods are put in the freezing compartment 4a, and foods such as vegetables and tofu that need refrigeration are put in the refrigerating compartment 4b. Also,
For example, foods such as canned foods and retort foods that do not require refrigeration or refrigeration and parcels other than foods are placed in the room temperature room 4c. Then, after turning on the operation switch 47, the lid 3
And close it with the master key to lock it.

When the operation switch 47 is turned on, the air cooling device 22 is activated, and the high-temperature and high-pressure gas refrigerant compressed by the compressor 23 flows into the condenser 24. Then, in the condenser 24, the air intake port 29 is rotated by the rotation of the fan 26.
The refrigerant that has exchanged heat with the outside air (see the arrow in FIG. 4) that blows through the first machine chamber 5a to the air exhaust port 30 is condensed by the expansion valve and then flows into the evaporator 25. On the other hand, the air in the freezer compartment 4a is sucked into the second machine compartment 5b from the air suction port 33 by the rotation of the fan 27, and the evaporator 25
And exchanges heat with the refrigerant as it passes through. This evaporator 25
The refrigerant endothermically evaporated by the heat exchange in the compressor returns to the compressor 23, while the cooled air flows from the evaporator 25 to the fan 2
7, the duct 32, the through hole 31, and the duct chamber 10 in order, and blows out from the air outlet 34 into the freezing chamber 4a (FIG. 3).
See the arrow). Since the air is circulated and cooled in this way, the temperature in the freezer compartment 4a drops sharply to a predetermined temperature.

Part of the cool air blown from the air outlet 34 into the freezer compartment 4a flows into the refrigerating compartment 4b from the ventilation holes 38 of the partition plate 35 by natural convection, and replaces it in the refrigerating compartment 4b. Air of relatively high temperature flows into the freezer compartment 4a side from the ventilation hole 38 of the partition plate 35. As a result, the temperature inside the refrigerator compartment 4b also drops. However, the freezer 4 here
Since the flow of air generated between a and the refrigerating compartment 4b is not forced by the fan and is limited according to the opening area of the ventilation hole 38, the temperature in the refrigerating compartment 4b is not as low as in the freezing compartment 4a. I won't. That is, in this home delivery cool box 1, the temperature in the refrigerating room 4b is 20 ° C higher than that in the freezing room 4a.
Since the opening area of the vent hole 38 is set to be higher in the front-rear direction, if the temperature in the freezing chamber 4a is controlled in the range of -25 ° C to -5 ° C, the temperature in the refrigerating chamber 4b is generally 5 ° C to. 15
It will be kept in the range of ° C. Furthermore, room temperature room 4
Since c is separated from the freezer compartment 4a by a partition plate 36 having a heat insulating property, its room temperature becomes substantially equal to the outside air temperature.

The customer who returns home unlocks the lock device of the home delivery cool box 1 using the key handed from the courier, then opens the lid 3 and stores the storage space 4 (freezer compartment 4).
a, the refrigerating room 4b, the room temperature room 4c). Then, after turning off the operation switch 47, the lid 3 is closed and locked again. (The reason for locking is to prevent mischief by others.)

According to the home delivery cool box 1 configured as described above, the following effects can be obtained. That is, since it is not necessary to prepare the cold storage material, the labor and labor of the delivery staff can be greatly reduced, and the temperature in the accommodation space 4 can be kept substantially constant regardless of the passage of time. Therefore, for example, if the customer's return home is significantly delayed, or if the outside temperature rises unexpectedly, the freshness of the stored fresh food may decline or the frozen food may thaw. Absent. Further, since the lid 3 can be locked with the lid 3 closed, the housed goods housed therein will not be stolen or the housed goods will be contaminated.

The accommodation space 4 has three compartments (freezing room 4a, refrigerating room 4b, room temperature room 4) having different temperature zones.
Since it is divided in c), various home deliveries such as frozen foods, fresh foods, and retort foods can be stored under optimum temperature conditions, and the temperature is actually controlled. Is only the freezer compartment 4a, and the refrigerator compartment 4b
Since there is no temperature sensor or cold air outlet in the
There is also an effect that the simple structure can be provided and the home delivery cool box 1 can be supplied at low cost.

Further, since the partition plates 35 and 36 are detachable, for example, when a large amount of frozen food is to be stored, the partition plate 36 should be removed so that the room up to the room temperature chamber 4c becomes a freezing chamber. On the other hand, when a large amount of food that requires refrigeration is to be stored, the partition plate 36 is replaced with the partition plate 35.
It is possible to replace the room with the same ventilation hole as the room temperature room 4c to make it a refrigerating room. In this way, the volume ratio of each temperature zone can be changed according to the contents of the delivered product. It also has advantages.

Further, the operation switch 47 can stop the air cooling device 22 when it is not necessary to prevent waste of electric power, and the operation switch 47 can be used as a contact surface with the lid body 3 of the box body 2. Since it is provided and cannot be operated unless the lid 3 is opened and the lid 3 is opened, it is possible to prevent the trouble that the switch is turned off by the mischief of another person.

Further, according to the above-mentioned home delivery service method, the delivery staff only possesses one master key to lock and unlock the home delivery cool box 1 installed at each of a plurality of customers. Since the parcels can be stored in the storage space 4, a large number of keys are managed and used differently as in the case where each parcel cooler box 1 has an individual key with a different key code for delivery. No need to
It is possible to obtain an effect that the time and effort required for key management and locking / unlocking can be significantly reduced.

Needless to say, the present invention is not limited to the embodiment described above. For example, in the above description, the operation switch 47 is provided on the abutment surface of the box body 2 with the lid body 3. However, on the contrary, the lid is provided. Even if it is provided on the abutting surface of the body 3 with the box body 2, substantially the same effect as described above can be obtained. Also, instead of the "butt face"
Even if the operation switch is provided on the inner surface of the box body 2 or the lid body 3 facing the accommodation space 4, the effect of preventing mischief of another person can be obtained. However, in this case, it may be difficult to operate the switch due to the housed goods in the house, or the operation switch may be inadvertently switched due to hitting the housed goods, so as described above, drive to the "butting surface". It is more preferable to provide a switch.

Further, although the case where the cylinder lock is used as the lock device has been described above, the lock device according to the present invention is not limited thereto, and for example, a magnetic card or an IC card is used as a key, or a so-called keyless entry device. It is also possible to adopt an electric lock using an infrared or radio wave transmitter. Also, in the above, both the locking operation and the unlocking operation were performed using the key, but the key is used only when unlocking, and the locking is an automatic lock type that is automatically performed when the lid 3 is closed. It is also possible to do it.

The freezing room 4a, the refrigerating room 4b, and the room temperature room 4
If you prepare a “carrying basket” with a handle with a size and shape that can be stored in c without any gaps, sort the parcels in advance before delivery, and store them in each carrying basket. The work at the front becomes easier, the efficiency of delivery is improved, it is easier for the customer to take out the parcels, and it is not necessary to individually package the parcels, so the consumption of packaging materials is reduced. The effect of being able to do is expected.

When a house or the like is built on the assumption that the cool box for delivering goods according to the present invention is used, a recess for accommodating and installing the cool box for delivering goods is formed on the wall surface near the entrance door in advance. It is also possible to keep it. This is preferable because it is possible to prevent the width of the corridor from being narrowed due to the installation of the home delivery cool box, particularly in the case of an apartment house.

[0037]

As described above, according to the cooler box for home delivery according to the present invention, it is not necessary to prepare the cold storage material as in the conventional case, so that the labor and labor of the delivery staff can be greatly reduced. In addition to being able to do so, it is possible to keep the temperature inside the accommodation space almost constant regardless of the passage of time, such as when the customer's return home is significantly delayed or the outside temperature rises unexpectedly. , The freshness of the stored fresh food will not be deteriorated and the frozen food will not be thawed. Also, since the lid can be locked with the lid closed, the housed goods housed therein will not be stolen or the housed goods will be contaminated.

Since the operation switch is provided,
When you do not need it, you can stop the air cooling device to prevent waste of power, and the operation switch cannot be operated unless you unlock the locking device and open the lid, so it is not a prank for others. Operation switch is turned off by
You can also avoid the trouble of getting F.

In addition, by the partition plate having the ventilation hole, the accommodation space is divided into a freezing room in which the air inlet and the air outlet are opened and a refrigerating room communicating with the freezing room through the ventilation hole. It is possible to store various types of parcels such as frozen foods and fresh foods under optimum temperature conditions, and since it is not necessary to provide a cold air outlet in the refrigerating room, a simple structure can be achieved. The effect of being able to supply the home delivery cool box at low cost is also obtained.

Further, by partitioning the accommodating space with a partition plate having a heat insulating property, a room temperature room which is isolated from the air inlet and the air outlet is formed in the accommodating space. It is possible to suitably store home-delivery items that do not require freezing and refrigeration, and suppress waste of electric power due to unnecessary refrigeration.

According to the home delivery service method of the present invention, the delivery staff only possesses one master key to unlock the home delivery cold storage boxes installed at a plurality of customers. Since the parcels can be stored in the storage space, there is no need to manage a large number of keys and use them differently as in the case of carrying an individual key with a different key code for each parcel cooler box. The effect of significantly reducing the time and effort involved in key management and unlocking operation is obtained.
