[Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view showing a refrigerator-freezer according to an embodiment of the present invention. A compressor 3, a main substrate 4, and a control board 5 are disposed in the machine room 2 on the lower rear surface of the refrigerator main body. The inside of the ice box main body 1 is divided by the partition wall 12 into an upper refrigerating chamber (R chamber) 1〇 and a lower freezing chamber CF chamber 11). The ruler chamber 1 is further separated by the partition plate 13 to form a vegetable compartment (V chamber) 14 in the separated lower portion. A space is left near the rear wall of the refrigerator main body 1, and the R chamber front cover 15 is disposed at the back of the chamber 1 to form the passage 16; the F chamber front cover 17 is disposed at the back of the F chamber n to form the passage 18 . The lower end portion of the diverticulum front cover 15 is folded rearward into an L-sub-shape. This bent portion 19 separates the vegetable compartment (V chamber) 14 from the upper R chamber H) together with the front isolation panel 13. / Figure 2 shows the refrigeration cycle of the cold storage refrigerator of this embodiment. The refrigeration cycle reduction compressor 3, the condenser 21 refrigerator compartment capillary f (R chamber capillary), the = room cooling evaporator (R chamber evaporator) 23, and the r chamber device (F chamber evaporator chamber cooling evaporation ( aCCUmUlator) 28; make the compressor 3 rotate and 洧月匕斋 (4) 'fine in the R room code = conversion to make the refrigerator compartment cooling (R mode) and cold; east chamber d cycle, the above-mentioned refrigeration cycle R chamber evaporator 23, R ^ type) is carried out by the father. In the channel 16, the F-chamber evaporator 24 is disposed in the R chamber 18. The government fan 27 is disposed in the F room, and the machine room 2 is provided with a power board type woven board 5 in a space plate mainly composed of a compression circuit f and a space provided therein. The other two 4 are called the controller's micro-to-door 30. 13 130693 & 4Pif.d〇c [Wafi • To inform the R room, F room temperature status, operating status and other information for the indicator plate 32 ° in the refrigerator body The appropriate position of 1, that is, the place where the outside air temperature can be measured without being affected by the internal temperature of the refrigerator, is equipped with a room temperature sensor 35, and in order to detect the temperatures of R to 10, F to 11, respectively, an R chamber temperature sensor is provided. The F to temperature sensor 37' is also mounted with an evaporator temperature sensor 38, which is transmitted to the control substrate 5 through the wiring. With the cold bead refrigerator having the above configuration, in the R chamber cooling mode, the _ switching valve 29 switches the refrigerant flow path so that the refrigerant flows toward the R chamber evaporator 23 side and passes through the R chamber evaporator 23, since the R chamber blower 24 is pressed Normally, the direction is rotated (forward rotation), and the cold air cooled by the portion of the Han room evaporator 23 is blown out to the upper portion and the side surface in the R chamber 10 in the R chamber passage 16, and the R chamber passage is taken in from the lower rear portion of the Rt 10 16 'The cold air is circulated in the R chamber 10 by this 4-turn passage, thereby cooling the chamber 10. Regarding the cooling of the vegetable compartment (the chamber) 7", the cold air returned from the rear portion to the R chamber passage 16 along the partition plate 13 by the cold air circulating in the R chamber 10 cools the partition plate 13, that is, the v chamber μ is cooled by The ceiling is indirectly cooled. When the temperature of the R chamber calculated by the control substrate 5 based on the temperature signal detected by the R room temperature sensor 36 is at a specified value, the R chamber cooling mode is stopped. Another aspect 'cooling in the F chamber In the mode, the 'switching valve 29 converts the refrigerant production route so that the refrigerant flows toward the F chamber evaporator 26 and passes through the ρ chamber generator 26. Since the F chamber blower 27 is rotated, the chamber is evaporated in the F chamber passage 18. The cooled cold air from the portion of the device 26 is blown from the rear portion into the F chamber η, and 'intakes from the lower portion of the F chamber 11 into the F chamber passage 18, and the cold air 14 1306935 l04pif.doc %Uf

The F chamber 11 is circulated to cool the F chamber 11. When the temperature of the F chamber of the nose by the control substrate 5 based on the temperature signal detected by the ρ chamber temperature sensor 37 is below a specified value, the F chamber cooling mode is stopped. Next, in the above-described R chamber cooling mode and F chamber cooling mode, the rotational speed control of the compressor by the PID control and the display of the temperature inside the freezer for the indicating plate 32 will be described. In order to keep the internal temperature of the refrigerator in the R chamber and the F爹 constant, the upper and lower fluctuations of the temperature in the refrigerator are calculated as [ρΙΕ), and the necessary compressor rotation speed is calculated. In this regard, the rotation frequency of the compressor 3 is calculated by applying the following calculation formula once per minute. [Formula 1]

Fnew^oid+O.O^*^^^ ^+Q Q|5et.2 * · · · Here ' Fnew is the new compressor frequency value; Fcld is the instantaneous value of the compressor frequency. [[2] et=(Tr-Trmid)*2 + (Tf-Tfmid)*3 — where 'Tr is the detected temperature of the R chamber temperature sensor; Trmid is R, the intermediate value of the operating temperature; Tf*F chamber The temperature of the temperature sensor; Tfmid is the intermediate value of the operating temperature of the F chamber. In addition, et_ is that et ’ et_2 before 1 minute is et before 2 minutes, and so on. Then, as the PID initial value at the time of restart of cooling, it is cooled, and. The HD value at the time of the beam starts the compressor 3 only at a low rotation frequency of 1 SHz, for example. Yu Han, the calculation of the temperature in the refrigerator indicated by the indicating plate 32 is performed.

Regarding the ρ chamber temperature indicated by the indicating plate 32, Tfdp_new is a new expression value; Tfdp-old is the present value, and the following calculation is performed. [Formula 4] 11 ""

Tfdp-new=Tfdp.〇ld+ ( Tf-Tfdp-old ) *Kf+Cf Here, Kf and cf are _7 when the temperature rises (Tf^Tfdp_old), and when the temperature drops (the price is caught) G 〇 ιι〇, 0.01 分别, respectively, using the flowchart of FIG. 3, the table of FIG. 4, and the time chart of FIG. 5, when the R chamber cooling mode of the cold storage refrigerator having the above configuration is switched to the F chamber cooling mode. control. The switching of the switching valve 29 causes the refrigerant to flow to the r chamber of the r chamber. The compressor 3 is in the R chamber cooling mode in the rotating operation (step S1), and the control substrate 5 takes the R chamber temperature sensor 37. Detecting I ^ According to this calculation, the substantial temperature of the R chamber is determined whether the cold is cold or not. U In the R chamber cooling mode, the R chamber blower 24 is rotated forward. If the temperature is not cooled, turn to the R chamber cooling mode; if the temperature is cold, stop the R chamber cooling mode (step S3). ?曰疋 When the R chamber cooling mode is stopped, the switching valve 29 is switched to the ρ % - side, and shifts to the F chamber cooling mode (step S5). Main-aged Mao Jie At the same time as the mode switching control, the control substrate 5 is passed to the temperature sensor. The detection signal is taken to obtain the outside air temperature RT. It is then judged whether or not the outside air temperature rt is a specified temperature 'e.g., lower than the return is 2 〇〇c (step j § 7). If the external temperature RT is below the specified temperature, 'set τ ΐ for the vegetable room forced cooling running time (for example: 5 minutes)' and set the R chamber blower 24 reverse rotation speed to low speed (for example: 1200 RPM), so that the R chamber blower 24 is reversed ( Step 89, 811, 813 people). If the outside air temperature is higher than the specified temperature, set T2 to the vegetable room forced cooling running time (for example, 1 minute), and set the R chamber blower 24 reverse rotation speed to high speed (for example, 16 〇〇 RpM). The R chamber blower 24 is reversed (steps S9B, S11B, S13B). Due to the reversal of the R chamber blower 24, the cold air from the R chamber blower shown in Fig. 6 first passes through the R chamber evaporator 23 in the R chamber passage, and is cooled by the low temperature, and the cold air is returned from the cold air return port below the passage 16. R胄1〇 causes it to flow in the opposite direction of the R chamber 1G, thereby forming a reverse circulation flow path. The k-to-(V to) 14 originally blown by the cold air blown from the lower portion of the R chamber passage 16 to the R chamber can be forcibly cooled strongly. If the vegetable room age j cooling run time τ > 5 will confirm the R room evaporator temperature sensor 38 2 1 soil board, such as: 3. . ), then let the R chamber drum = still at the specified temperature, use the R chamber evaporator 23 _ remaining low into the chamber 10 for continuous circulation to benefit the operation (step S15,, - = "rolling in the RR chamber evaporator temperature rise To a higher than the specified temperature, then ~.

If the F-chamber cooling mode ends the box until the end of the cold room temperature drop mode, the cooling mode of the cooling mode mode is stopped by the cooling stop 24, so that the portion passing through the R chamber evaporator 23 is passed. The cold air used for the first time is blown as v residual low-strength cooling V chamber 14 t vt 4; 1 tea-making board 13, so that the same cold pair can be used to correspond to the ambient temperature of the refrigerator.

In the state where the cold air in the R chamber 10 is circulated in the normal circulation route, the cold air flows back to Vt14 to reverse the R chamber blower 24, and a part of the cold air flowing through the R chamber passage 16 flows into the V chamber 14, The v chamber 14 can be cooled strongly. ^ Thus, in the third embodiment, due to the isolated portion R of the front cover 15 and the bent portion η of the v chamber 14 provided to form the air supply passage 16 on the uranium side of the R chamber evaporator 23, The air supply passage μ communicates with the v chamber 14 to expose the opening 40, and the cold air can be sent to the V chamber only during the reverse rotation operation of the R chamber blower 24, so that the V chamber 14 can be cooled more efficiently.

A refrigerator-freezer according to a fourth embodiment of the present invention will be described with reference to Figs. 12 and 13 . The fourth embodiment has a feature in the room temperature control of the control board 5. The configuration of the machine and the refrigeration cycle are as shown in the second embodiment shown in Figs. 7 to 9 . The control substrate 5 is calculated by the temperature detection signal Tr of the R chamber temperature sensor 36 provided near the cold air return port at the lower portion of the R chamber passage 16 for the management of the R chamber temperature, and the substantial temperature of the R chamber is obtained. Trdp-new, expressed as the R chamber temperature on the indicator board 32, based on this 20 I306935〇4pifd〇c wig

Calculate the temperature Trdp-new to control the pid of the 3 speed of the reducer. This HD control and temperature gauge are not controlled. It has been explained in the consistent application of the brother. When the R chamber blower 24 is reversed, since the cold air is lowered in the R chamber passage 16 to form a cold air flow blown from the cold air return port to the R chamber 10, the cold air which is lower than the temperature in the normal R chamber cooling mode will contact the r chamber. The temperature sensor 36 then calculates the substantial temperature of the R chamber as a low temperature value. Therefore, the control substrate $, as in the PID control of the compressor 3 shown in the graph of Fig. 12, excessively controls the rotation of the compressor on the low speed side, which may cause a phenomenon of weakening the forced cooling of the v chamber. Moreover, the temperature of the R chamber indicated by the indicating plate 32 may also be lower than actually. Therefore, in the present embodiment, as shown in the flowcharts S8, S1 of the flowchart of FIG. 13, when the R chamber blower 24 is reversely controlled, the compressor operation is controlled by the R chamber substantial temperature Trdp-new immediately before the control is implemented. At the end of the reverse operation of the R chamber blower 24, the cooling control after the resumption of the substantial temperature of the R chamber immediately before the start of the reverse rotation operation is performed (step S14). The flow chart of Fig. 13 is represented by the same step number as the processing of the general portion of the flowchart of the second embodiment shown in Fig. 7. v Thus, in the fourth embodiment, as shown in the graph of Fig. 14, in the γ-chamber forced cooling operation mode, the compressor 3 controlled by piD is smooth, that is, the V-chamber cooling can be performed efficiently. Year The fifth embodiment will be described with reference to FIG. This embodiment has features on the R chamber temperature representation of the indicator panel 32. Regarding the mechanical configuration and the refrigeration, the corresponding portions of the first embodiment shown in Figs. 1 to 6 are used. The garment control substrate 5 is subjected to R chamber temperature management, and is used in the R chamber temperature sensing provided in the R chamber 21 130693, 5b '4pif.doc 95. 11A of Fig. 1 to correct the vicinity of the lower cold air return port of the refill passage 16 The temperature detection signal Tr of the device 36 is obtained by calculating the R chamber substantial temperature Trdp-new based on the calculation, and the R chamber temperature is indicated on the indicating plate 32. However, as explained in the fourth embodiment, when the R chamber blower 24 is reversed, the cold air which is lowered in the R chamber passage 16 forms a cold air flow blown from the cold air return port to the R chamber 10, which is higher than the usual R The cold air having a low temperature in the room cooling mode will contact the R chamber temperature sensor 36, and the actual temperature of the R chamber will be calculated as a low temperature value as shown in the graph of FIG. Thus, it is also possible to cause the control substrate 5 to generate a phenomenon in which the temperature of the R chamber indicated on the indicating plate 32 is lower than the actual temperature. Therefore, in the present embodiment, as shown in step S6 of the flowchart of Fig. 16, when the R chamber blower 24 is reversely controlled, it is indicated that the R chamber substantial temperature Trdp-new before the control is to be performed remains unchanged, and the calculation of the R chamber temperature is stopped. When the reverse operation of the R chamber blower 24 is completed, the temperature calculation after the restart of the ruler substantial temperature immediately before the start of the reverse rotation operation is performed (step S14). On the other hand, the flowchart of Fig. 16 is indicated by the same step number for the processing of the general portion of the flowchart of the first embodiment shown in Fig. 5. Thus, in the fifth embodiment, as shown by the graph of Fig. 17, the R chamber temperature indicates that there is no difference from the actual R chamber temperature, and the reliability of the temperature expression can be improved. Further, as also explained in the fourth embodiment, for the control of the compressor, the R chamber temperature calculation can also be controlled by stopping the reverse operation of the r chamber blower 24. The following δ is a description of the cold embodiment of the sixth embodiment of the present invention; At 22 I306935〇4p,d〇c

In the first to fifth embodiments, in order to forcibly cool the v chamber, the temperature sensor 41 is provided in the V chamber 14 as shown in FIG. 18, so that if the detection temperature of the v chamber is below the specified temperature, the stop V chamber can be employed. Control of forced cooling operation: This can prevent the V chamber 14 from being forced to cool too much and causing frostbite to cause vegetables. The present invention has been disclosed in its preferred embodiments as a matter of course, and is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is determined by the scope of the patent application. Tian [Simple description]
