Abstract

PURPOSE:To change refrigerator temperature according to a target by a method wherein a main control part controls load based on target refrigerator temperatures of various time zones stored in a storing part and a present refrigerator temperature detected by a temperature detecting means. CONSTITUTION:In the case that target refrigerator temperatures of various time zones are set by a temperature setting means 4, a set temperature is stored in a storing part 5. In the case that there is no temperature setting, a main control part 7 refers to a present time from a timer part 6, reads in a target refrigerator temperature of the present time from a storing part 5, and compares the target refrigerator temperature with the refrigerator inside temperature of the present time. If the target refrigerator temperature is higher than the present temperature, a load 1 is operated through a load control means 2 to cool a refrigerator. To the contrary, if the target refrigerator temperature is lower than the present temperature, the load 1 is stopped through the load control means 2 to interrupt cooling of the refrigerator.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a temperature control device for a refrigerator that controls and changes cooling temperature over time.

(Prior art) Normally, the cooling temperature of a conventional refrigerator is, for example,
As seen in JP-63971, the setting of the cooling target temperature is limited to one, and the cooling is only performed to that temperature.

(Problem to be solved by the invention) However, in refrigerators used for commercial purposes,
It is necessary to vary the temperature inside the refrigerator over time.
Each time, there was a drawback that the temperature had to be reset to the required temperature when the time came.

An object of the present invention is to provide a temperature control device for a refrigerator that solves the above problems.

(Means for Solving the Problems) The present invention has the above object to provide a load control means for driving and controlling the cooling load of a refrigerator, a temperature detection means in the refrigerator, a storage unit, and a cooling temperature target for each time period. temperature setting means for registering and storing in the storage section, a timer section for counting the current time, the temperature inside the refrigerator at the current time detected by the temperature detection means, and a target for each time zone registered in the storage section. and a main control unit that controls the load control means by comparing the cooling temperature with the temperature corresponding to the current time, so that the temperature inside the refrigerator at the current time becomes the target cooling temperature corresponding to the current time. The above is achieved by controlling the load control means.

(Function) According to the present invention described above, the temperature inside the refrigerator is always automatically controlled to the target temperature at the current time read out from the storage section.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, in which 1 is a load for cooling the inside of the refrigerator, 2 is a load control means for controlling the load 1, and 3 is for detecting the temperature inside the refrigerator. Temperature detection means; 4 is a temperature setting means for temporally setting the target internal temperature of the refrigerator; 5 is a storage unit for storing the target temperature for each time period set thereby; 6 is for counting the current time. A timer section 7 is a main control section that compares and judges the current time of the timer section 6 and the target temperature for each time zone of the storage section 5, and controls the load control means 2.

FIG. 2 is a flowchart illustrating the operation shown in FIG. 1 above. Hereinafter, referring to this, the operation steps in Fig. 1 will be explained.
This is abbreviated as .

First, when the power is turned on and the temperature setting means 4 sets the target internal temperature for each time period, the set temperature is stored in the storage section 5 (Sl). If the above-mentioned temperature setting has not been made, the main control section 7 checks the current time from the timer section 6 (S), reads the target internal temperature at the current time from the storage section 5 (S3), Moreover, the temperature detection means 3
Reads the current internal temperature detected by (S4),
The target internal temperature is compared with the current internal temperature, and if the target internal temperature is higher than the current internal temperature (S, Y), the load 1 is activated via the load control means 2. If the target temperature inside the refrigerator is lower than the current temperature inside the refrigerator (S6/N), the operation of the load 1 is stopped via the load control means 2 to cool the interior of the refrigerator. Stop (S,).

Each of the above steps is sequentially and repeatedly performed.

As described above, according to the present invention, the target internal temperature for each time period is stored in the storage section 5, the current time in the timer section 6, the target internal temperature for each time period in the storage section 5, and the temperature detection means. By controlling the load 1 by the main control unit 7 based on the refrigerator temperature at the current time in step 3, the temperature of the refrigerator can be controlled according to the time of day without changing the target temperature inside the refrigerator every time it is necessary. It becomes possible to do so.

(Effects of the Invention) As is clear from the above explanation, the present invention allows the temperature inside the refrigerator to be controlled according to the time of day by setting and storing the target temperature inside the refrigerator for each time period. It has the effect of being able to change the temperature inside the refrigerator as per the target without changing the temperature inside the refrigerator, and it can be used to great advantage.
