The internal temperature control switch y1 is a thermoswitch that detects the temperature inside the refrigerator, and the movable contacts a and normally closed (11j It operates by being energized through a fixed connection to cool the inside of the refrigerator.Timer motor T
M and the timer switch SW2 constitute a timer, and the timer motor TM rotates a cam by being energized from the AC power supply AC through the adjustment switch 8WiY in the refrigerator, and this cam operates the timer switch SW.
The movable contact piece a of No. 2 is driven at predetermined intervals. The defrosting heater H is powered by AC power when the timer switch SW2 is turned off.

ている。However, in this defrosting mlJ control device, the timer motor TM
is energized through the internal temperature adjustment switch s'Wi &, the defrosting cycle is determined by the integration of the timer σ) period and the internal temperature adjustment switch sw1o), and 47 hours. The period of the timer is divided by the on/off (-cent (timer operation rate) of the internal temperature adjustment switch SWi). Therefore, the defrosting cycle in the four seasons is as follows.

午か低い。Also, the amount of frost is different between thighs and winter. In other words, in the summer when the refrigerator door is opened and closed frequently and there is a lot of moisture in the outside air, it is easy for frost to build up, and the opposite is true in the winter. Therefore, in summer, the defrosting cycle is short and there are many 1M violets, so the frost cannot be completely removed.
In winter, the defrosting cycle is long and the amount of sheathing is small, so defrosting is often carried out even when there is no frost, resulting in wasted energy and reliability.
It's low in the afternoon.

ている。In order to compensate for this deficiency, a method has been adopted in which the period of the timer is changed in multiple stages depending on the outside air tr=w. However, in this method, the timer cycle is changed in multiple stages depending on the outside temperature, resulting in a significant increase in cost.
本発明は上記のような欠漬ケ改善し、安価で信頼性が高
い除霜制御装置を提供することを目的とする。It is an object of the present invention to provide a defrosting control device which is inexpensive and highly reliable, and which improves the problem of water shortage as described above.
以下図面を参照しなから本発明について実施例馨あげて
貌明する。The present invention will now be explained in more detail with reference to the drawings.

点ｆに切換わる。In this embodiment, a temperature-sensitive switch SW4 made of a bimetal thermoswitch is provided in the defrosting control device described above, and a so-called "switch 5" is added to the timer. #
& Temperature switch history 4 consists of a metal thermoswitch, etc. that detects the outside air temperature outside the refrigerator, and when the outside air temperature exceeds the set temperature, the movable contact d switches from the fixed contact e to the fixed contact f. .

る。When the outside temperature reaches or exceeds the set temperature, the temperature sensing switch SW4 is turned off, and the defrosting cycle is extended without passing through the timer motor TM and the indoor temperature adjustment switch SW1. Now, if the set temperature of the temperature-sensitive switch S'w4 is set to 20°C and the timer cycle is set to 11H, the defrosting cycle will be as follows.

リレー等を設ける必費かない様になっている。The current flowing through the temperature-sensitive switch SW4 is about 10-odd mA, and the temperature-sensitive switch SW4 may be an inexpensive Napai metal thermoswitch or the like. Even if the ah switch SW4 is switched during defrosting, it will have no effect at all (there is no need to provide a self-holding circuit or a guarantee circuit relay, etc.).

２の方フより僅かに遅くオフする。If the switch SW5 is not present, when the timer switch history 2 is turned on with the temperature sensing switch SW4 on, the defrosting heater H may not be energized when the Atsunai temperature shrine switch SWi is turned off. In order to solve this problem, a switch SW5 is provided, and the switch SW5 is a timer switch SW5 as shown in the time chart of Fig. 3.
Turn on/off and timer switch SW slightly earlier than turn on of 2.
The second one turns off slightly later than the second one.
