もさける事が出来なかつた。 Generally, the freezer compartment of a refrigerator can be cooled to -15 to -25℃, but it is a well-known fact that when making frozen foods, it is effective to freeze them at a lower temperature for a shorter time to maintain the quality of the food. It is. Therefore, conventionally, in order to maintain the low temperature, a part of the freezer compartment was further partitioned with a heat insulating wall to provide a quenching room. but,
Even in this case, the cooling operation is stopped during defrosting, so even though the temperature rise is insulated, the quenching chamber cannot be avoided.

ある。 In the figure, 1 indicates a refrigerator body, and a freezer compartment door 5 and a refrigerator compartment door 6 are attached to the front opening of the refrigerator body 1 by means of an upper hinge 2, a middle hinge 3, and a lower hinge 4 so as to be openable and closable. 8 is a rapid cooling chamber, and a freezing chamber 7
A quenching chamber cooler 16 is provided inside the quenching chamber 8 and its surroundings are insulated and isolated by a heat insulating material (not shown). The refrigeration system 17 includes a compressor 9, a condenser 10, a freezer compartment electromagnetic valve 11, a first capillary tube 12, and a freezer compartment cooler 13 connected in order in an annular manner. Cooling chamber cooler 16 in the rapid cooling chamber 8
are piped in the refrigeration system 17 in parallel with the freezer compartment cooler 13 of the freezer compartment 7, and are provided with a first capillary tube 12 and a second capillary tube 15, respectively. The flow of refrigerant to the freezer compartment cooler 13 is controlled by the freezer compartment solenoid valve 1.
1, and the flow of refrigerant to the quench chamber cooler 16 is controlled by a quench chamber solenoid valve 14. The freezing chamber solenoid valve 11 is opened when no electricity is applied, and the quenching chamber solenoid valve 14 is opened when electricity is applied.

却を継続することができる。 Next, the control system of the present invention will be explained with reference to the electrical wiring diagram shown in FIG. 18 is a thermostat (freezer compartment thermostat) that controls the temperature of the freezer compartment 7, and when the switching piece 19c of the timer 19 is on the cooling side contact 19a side, the compressor 9 is operated and cooling is performed. conduct. When the switching piece 19c switches to the contact 19b, the defrost heater 21 is energized, the compressor 9 is de-energized, and the freezer compartment solenoid valve 1 is turned off.
1 is energized and closed, cooling operation is stopped, and defrosting is performed. When defrosting is finished, bimetal 22
By the action (opening), the timer motor operates, the switching piece 19c switches to the contact 19a, restarting the energization to the compressor 9, and stopping the energization to the freezer compartment solenoid valve 11 to open it. , returns to cooling operation. The same cycle described above is then repeated. 20 is a single-pole double-headed rapid cooling switch, and by turning it on,
A circuit is formed to short-circuit the contact 19a of the timer 19 from one contact 20a, and the compressor 9 is energized and operated even when the switching piece 19c is on the defrosting side contact 19b side. Then, the other contact point of the quenching switch 20 energizes the quenching chamber solenoid valve 14 to open it, thereby cooling the quenching chamber cooler 16 of the quenching chamber 8 . At this time, the freezer compartment solenoid valve 11 is activated at the defrost side contact 19b of the timer 19.
Since it is connected to the power source via, the freezer compartment solenoid valve 11 is also energized. Since the freezer compartment electromagnetic valve 11 closes when energized, the flow of refrigerant to the freezer compartment cooler 13 is cut off, and the refrigerant flows only to the cooling compartment cooler 16, and normal defrosting operation is performed. The rapid cooling chamber 8 can continue cooling even while the freezing chamber 7 is being defrosted.

冷凍食品の品質確保に効果を有する。 As is clear from the above description, the refrigerator of the present invention is equipped with a quenching chamber within the freezer compartment, and by closing the contacts of the quenching switch, both ends of the thermostat and timer are short-circuited and the compressor is forcibly energized.
The quenching chamber can continue cooling operation even while defrosting the freezer compartment, so the quenching chamber can always maintain a low temperature.
Effective in ensuring the quality of frozen foods.
