Description of the invention (1) Du printed by the Ministry of Economic Affairs on behalf of consumer cooperation of the Hui Property Bureau [Technical Field to which the Invention belongs] The present invention relates to a refrigerator, which alternately supplies a refrigerant to a cooler for cooling and a cooler for freezing. Cool the refrigerator side and the freezer side alternately. [Problems to be Solved by the Invention] The conventional refrigerator is generally a system formed by a cooler and a cooling air circulation fan to cool the refrigerating compartment, the vegetable compartment and the cooler than these temperatures; Dongzhi 'will cool The exhausted air cooled by the device is sent to each room by the cold air circulation fan through the cold air circulation pipeline or electric air lock to cool each room. However, since the temperature of the cold air supplied to the freezer or vegetable compartment is as low as the temperature of the cold air supplied to the freezer or vegetable compartment, the cold air circulation or electric air lock that supplies cold air to the refrigerator or vegetable compartment must not No heat insulation is applied, so the volume of the cold air circulation pipeline or electric air brake becomes larger, which is the main reason that hinders the increase of the volume ratio (the internal volume corresponding to the size outside the refrigerator). In order to solve this problem, a refrigerator has been recently provided, each of which is provided with a cooler on the refrigerating compartment side and the cold beam compartment side, and alternately supplies the refrigerant to the refrigerating cooler and the freezing cooler, and alternately cools the refrigerating compartment side and the freezing compartment side. In addition, the number of rotations of the compressor or the cold air circulation fan is changed to control each cooler to a temperature suitable for the temperature zone of the cold storage room and the freezing room. The switching control method for the interactive cooling of the refrigerator is described as follows: First, the refrigerating compartment and the freezing compartment are each set to an OFF temperature lower than the target temperature and an ON temperature higher than the target temperature. Basically, when the shutdown temperature is detected by the temperature sensor for the refrigerating compartment and the temperature sensor for the freezer, the refrigerant is supplied to the cooler for refrigerating (hereinafter referred to as R 冷 _ 4 _ ----- --------------- 丨 Order ---------- line-'/ I 、, f Please read the phonetic on the back?

Description of Invention (2) Ministry model) and supply of refrigerant Switch to the state of the cooling cooler (hereinafter referred to as F cooling mode). According to this kind of interactive cooling, the temperatures of the refrigerating compartment and the cold beam room change up and down between the start-up temperature and the shut-down temperature, and the refrigerating chamber and the freezing chamber are each maintained at their target temperatures as their average temperatures. However, the above-mentioned switching control method, for example, in the winter when the temperature is low, because the heat transfer between the inside and outside of the refrigerator is small, the temperature of the refrigerating compartment rises slowly. When the temperature has not risen to the startup temperature, the F cooling mode ends. Enter the r cooling mode, which causes the problem that the average temperature of the refrigerator compartment is lower than the target temperature. In this regard, when the target temperature of the refrigerator is set to 2 τ, if the shutdown temperature is set to 15 × :, and the startup temperature is set to 2 · 5χ :, the average temperature of the refrigerator will not change even in winter. Too low. Recently, however, it has been considered to set the target temperature of the refrigerator to 1X: so that the food can be preserved with better freshness. In this case, it is controlled so that the shutdown temperature of the refrigerator compartment is set to, for example, 0.6 ° C, the startup temperature is set to, for example, fc, and the average temperature is 1 ° C. However, at this time in winter, before the temperature of the refrigerating compartment is raised to 丨. 4 < &c; the F cooling mode ends and the chilling cooling mode is started. Therefore, the average temperature of the refrigerating compartment is lower than the target temperature (1.0. The food is partially cold because of the low temperature. '-The present invention aims to provide a refrigerator in which the average temperature of the refrigerating compartment can be maintained near the target temperature even if the temperature changes. In order to achieve the above-mentioned object, the refrigerator of the present invention is characterized in that the size of the paper is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page)- HI > ^ 1 KI n- " -mouth, I ^^ 1 it ^ i vn line '' ^ 54 08 4

Description of the invention (4) Due to the termination at a low shutdown temperature, the average temperature of the refrigerating compartment is reduced to around the target temperature. In this case, the structure on the side of the refrigerating compartment may be made as follows: In addition to the shutdown temperature, a startup temperature higher than the target temperature is also set. The average temperature detected by the temperature sensor for refrigeration becomes When the temperature is lower or higher than the target temperature, the shutdown temperature and the startup temperature of the refrigerator compartment side increase or decrease at the same time. The start-up temperature of the refrigerator compartment side is used to estimate the load on the refrigerator compartment side by comparison with the temperature detected by, for example, a temperature sensor for refrigeration. Therefore, when the average temperature detected by the temperature sensor for refrigerating becomes lower or higher than the target temperature, 'not only the shutdown temperature on the refrigerating compartment side, but also the startup temperature is also high or low', it can be presumed that the heat load on the refrigerating compartment side is small. Or larger, can reach the target temperature faster. The average of the detection temperature of the temperature sensor for refrigerating is preferably determined every other specific time and compared with the target temperature. The temperature of the room where the refrigerator is set does not cause large changes in a short time, such as about 1 hour. Therefore, it is not necessary to reset the shutdown temperature of the refrigerator compartment every short time. From this point of view, it is reasonable to take every-longer time: take the average of the temperature detected by the temperature sensor for refrigeration and compare it with the target temperature before changing the shutdown temperature.

The number of rotations of 14 and the refrigerating circulation fan 21 is controlled so that the average temperatures of the refrigerating compartment 3 and the freezing compartment 6 can each reach their target temperatures. · In this case, the microcomputer 30 detects the shutdown temperature of the refrigerating compartment 3 and detects the shutdown temperature of the refrigerating compartment 3 at the refrigerating compartment temperature sensor 3 1 and performs R Switch between cooling mode and ρ cooling mode. Here, it is assumed that the target temperature of the refrigerating compartment 3 is 丨. 〇, the startup temperature is 1.4 ° C, the shutdown temperature is 0.6 ° C, and the target temperature of the freezer 6 is -18. (:, The startup temperature is -17 ° C, the shutdown temperature is -16X :. 1 Now suppose the freezer uses a temperature sensor 3 2 to detect the shutdown temperature (_19 ° C).

Description of the invention (9) In addition, the temperature sensor 3 1 for the refrigerator compartment detects the shutdown temperature (0.6. (:)), and the microcomputer 30 switches the three-way valve 26 to The compressor 25 communicates with the cooling cooler and stops the circulation fan 20 for cooling and drives the circulation fan 21 for refrigeration. Accordingly, the cooling mode is switched from the R cooling mode to the ρ cooling mode. In this F cooling mode, The air cooled by the refrigerating cooler 20 is sent to the ice-making room, the temperature conversion room 5 and the freezing room 6, and the respective rooms are cooled down. According to this, the detection temperature of the 'freezing temperature sensor 32' is cooled. It is gradually lowered as shown by the solid line in Fig. 2. On the other hand, in this F cooling mode, the refrigerating compartment 3 and the vegetable compartment 4 are not supplied with cold air. The detection temperature of the refrigerating compartment temperature sensor 31 is as shown in the figure. The number 2 gradually rises. In this way, the F cooling mode and the R cooling mode are alternately performed. In this case, the operation of the F cooling mode is performed by selecting the number of rotations of the circulation fan 21 in the compressor 23 and the cold. In the case of termination of the ρ cooling mode At that time, the temperature of the refrigerating compartment 3 rises to about the start-up temperature (丨), and the operation of the cooling mode is also the same at the end of the R cooling mode, the temperature in the freezer 6 rises to about the start-up temperature (_ΐ7 : Χ :). By this means, the average temperature of the refrigerating compartment 3 and the vegetable compartment 4 is maintained at a target temperature of 1 ° C, and the average temperature of the ice-making compartment and the freezing compartment 6 is maintained at _18 .. However, In the winter season when the temperature becomes low, as shown by the dotted line in FIG. 2, the temperature of the refrigerating compartment 3 rises slowly, and the cooling mode is terminated before it rises to the start-up temperature F. Therefore, the average temperature of the refrigerator compartment 3 becomes lower than rc, and the food may be partially frozen. This embodiment prevents this problem by the following configuration. That is, the microcomputer 30 reads the temperature sense of the refrigerating compartment at a certain short interval. 12_ This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 meals) Γ Please read the precautions on the back before filling in this Page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs

Description of the invention (10) The temperature detected by the detector 31 is stored in the RAM (memory mechanism) such as RAM or EEPR0M. In addition, the microcomputer 30 reads the temperature detected by the temperature sensor 31 for the refrigerating compartment stored in the memory every specific time, for example, every ^ $ hours, and calculates its average temperature τ (average temperature calculation mechanism). In a case where the average temperature T is lower than the target temperature T0, the microcomputer 30 shifts the shutdown temperature and the startup temperature by the startup and shutdown temperature changing mechanism to shift the correction temperature t obtained by the following formula. t; (T0-T) / 8 ............ (1) After this, as shown in Figure 1, the operation of R cooling mode is terminated at the shutdown temperature set to the south tC. As a result of this operation, the temperature of the refrigerating compartment 3 rising during the operation in the f cooling mode also becomes higher than before.
