(4) structure of three-way valve 11
Three-way valve 11 in freeze cycle 50 is described according to Fig. 6.
As shown in Figure 6, three-way valve 11 has: valve seat 32, is located at the bottom of valve cap (valvecase) 31; And valve body 33, be configured in the top of this valve seat 32.
On valve seat 32, be formed: R exports 32R, make cooling agent flow out and towards R evaporimeter 5 side; F exports 32F, make cooling agent flow out and towards F evaporimeter 4 side; And inflow entrance 34, cooling agent is flowed into from condenser 10 via entrance pipe arrangement 37.
Valve body 33 covers the R that valve seat 32 is formed to export 32R and F and export the mode of 32F and be configured in the top of valve seat 32, and be rotating with can carrying out Angle ambiguity by being subject to stepper motor (steppingmotor) (not shown) that pulse (pulse) controls.
And, on valve body 33, make the distance counted from rotating shaft 33a different from each other and the position of the circumferential direction that staggers and be formed with R groove 33R and F groove 33F at the lower surface of heavy wall section portion 33b.
By stepper motor, valve body 33 rotates predetermined angular to the clockwise direction shown in the arrow K in Fig. 6 in this example, thus R groove 33R and R outlet 32R or F groove 33F and F outlet 32F coincides with the upper and lower and is communicated with, or, F groove 33R, R groove 33F does not all export 32R, R and exports 32F and overlap with F, and F export 32R, F export 32F by valve body 33 close.

(5) electrical structure of refrigerator 1
Secondly, according to the electrical structure of clear ice case 1 block diagram of Fig. 7.
As shown in Figure 7, control control part 102 set on substrate and comprise micro computer (microcomputer), and be connected to motor, R fan 7, F fan 6, the C fan 18 of compressor 9.
And control part 102 is also connected to external temperature sensor 105, three-way valve 11, R sensor 106, F sensor 108, R evaporator sensor 112, F evaporator sensor 110 set on guidance panel 104 set on the door 301a of refrigerating chamber 301, guidance panel 104.
(6) refrigerating mode
In the refrigerator 1 of said structure, control part 102 is according to the detecting temperature of the R sensor 106 be located in F district 2 or Zone R 3, F sensor 108, carry out switching to three-way valve 11 to control, thus perform and make cooling agent flow to R evaporimeter 5 and the refrigeration refrigerating mode that only cools Zone R 3 is (following, be called " R pattern "), with make cooling agent flow to F evaporimeter 4 and only to the freezing refrigerating mode (hereinafter referred to as " F pattern ") that F district 2 cools.
(7) operating state of refrigerator 1
Secondly, the operating state of the refrigerator 1 of this example is described according to the flow chart of Fig. 8 and Fig. 9.
In step sl, control part 102 judges whether the detecting temperature of F sensor 108 is that the F that is more than or equal to preset starts temperature TF1 (such as,-18 DEG C) (step S1), if start temperature TF1 (such as being more than or equal to F,-18 DEG C) (that step S1 is (y)), then control part 102 starts F pattern (step S3).
If start temperature TF1 (no (n) of step S1) lower than F, then judge whether the detecting temperature of R sensor 106 starts temperature TR1 (step S2) for being more than or equal to R.
If the detecting temperature of R sensor 106 starts temperature TR1 (such as, 4 DEG C) (y of step S2) for being more than or equal to R, then control part 102 starts the R pattern (step S11) in Fig. 9.If start temperature TR1 (n of step S2) lower than R, then return step S1.
Control part 102 starts F pattern (step S3), namely, the R of three-way valve 11 is exported 32R and is set to full-shut position by control part 102 under F pattern, F is exported 32F and is set to full-gear, cooling agent is made to flow to F evaporimeter 4, and F fan 6 is rotated, the air cooled through F evaporimeter 4 is delivered to F district 2.
The rotating speed of compressor 9 coordinates the detecting temperature of F sensor 108 to control to carry out phase inverter (inverter).Such as, the detecting temperature of F sensor 108 is lower, then reduce the rotating speed of compressor 9 more gradually, energy-conservation to realize.
And, control part 102 judges that whether the rotating speed of compressor 9 is for being less than or equal to regulation rotating speed A (step S4), if for being less than or equal to regulation rotating speed A (that step S4 is (y)), then narrow the aperture (step S6) that F exports 32F.
If higher than regulation rotating speed A (no (n) of step S4), then judge that whether the detecting temperature of external temperature sensor 105 is for being more than or equal to set point of temperature B DEG C (such as, 27 DEG C) (step S5).
Such as, if carry out the FREQUENCY CONTROL in the inverter controlling of compressor 9 with 19Hz ~ 70Hz, then corresponding with 28.8Hz rotating speed corresponds to regulation rotating speed A.
If the detecting temperature of external temperature sensor 105 is for being more than or equal to set point of temperature B DEG C (such as, 27 DEG C) (y of step S5), then control part 102 narrows the aperture (step S6) that F exports 32F.
If the detecting temperature of external temperature sensor 105 is lower than set point of temperature B DEG C (n of step S5), then judge whether to terminate F pattern (step S7).
In step s 6, the rotating speed of compressor 9 is for being less than or equal to regulation rotating speed or outside air temperature for being more than or equal to B degree, and therefore the aperture that the F of three-way valve 11 exports 32F narrows to 1% ~ 50% (preferably 10%) by control part 102.
Further, judge whether to terminate F pattern (step S7).Exporting 32F by narrowing F, the decompression amount optimization of F evaporimeter 4 inside can be made, thus can contribute to energy-conservation.
Can optimized reason as follows.When the rotating speed height of compressor 9, if narrow the aperture that F exports 32F, then the decompression amount of F evaporimeter 4 can become excessive, thus can cause the decline of refrigerating capacity or energy-conservation deterioration.
And, when outside air temperature is low, it is inner that liquefied coolant is stranded in condenser 10 more, if therefore narrow the aperture that F exports 32F, then the cooling agent of the inside of F evaporimeter 4 can become not enough, thus cause the decline of refrigerating capacity or energy-conservation deterioration, therefore control part 102 does not narrow aperture and controls as full-gear, only have when compressor 9 is for being less than or equal to regulation rotating speed A or outside air temperature for being more than or equal to B DEG C, control part 102 just narrows F and exports 32F, thus by the decompression amount optimization of F evaporimeter 4.
In the step s 7, control part 102 judges whether to terminate F pattern, such as, if the detecting temperature of F sensor 108 becomes be less than or equal to F end temp TF2 (such as,-22 DEG C) (y of step S7), then control part 102 judges whether terminate F pattern and be converted to R pattern (step S8).If for being more than or equal to F end temp TF2 (n of step S7), then return step S4.
If the detecting temperature of R sensor 106 starts temperature TR1 (y of step S8) for being more than or equal to described R, then control part 102 is converted to R pattern, if start temperature TR1 (n of step S8) lower than R, then returns step S1.
Then, control part 102 judges that whether the F of three-way valve 11 exports 32F for narrowing state (step S9), if be full-gear (n of step S9), then advance to the step S11 shown in Fig. 9, if for narrowing state (y of step S9), then F is exported 32F and is set to full-gear (step S10).
The F of three-way valve 11 is exported 32F and carries out the full-gear stipulated time (such as by the state of narrowing by control part 102,5 seconds) (step S10), foreign matter in 32F is exported (such as by snapping in F, copper powder) etc. got rid of, and advance to the step S11 starting R pattern.
Control part 102 starts R pattern (step S11).In the r-mode the F of three-way valve 11 is exported 32F and be set to full-shut position, R is exported 32R and is set to full-gear, the coolant feed of condenser 10 is to R evaporimeter 5 in the future, and R fan 7 is rotated, and the air cooled through R evaporimeter 5 is delivered to Zone R 3.
Now, the detecting temperature that compressor 9 is also in R sensor 106 is lower, more reduces rotating speed, to carry out energy-saving operation.Then, step S12 is advanced to.
Then, control part 102 judges that whether the rotating speed of compressor 9 is for being less than or equal to regulation rotating speed A (step S12), if rotating speed is for being less than or equal to regulation rotating speed A (y of step S12), then advance to the step S14 that the R narrowing three-way valve 11 exports 32R, if higher than regulation rotating speed A (n of step S12), then judge that whether the detecting temperature of external temperature sensor 105 is for being more than or equal to set point of temperature B DEG C (step S13).
If the detecting temperature of external temperature sensor 105 is for being more than or equal to set point of temperature B DEG C (y of step S13), then control part 102 advances to the step S14 that the R narrowing three-way valve 11 exports 32R.
If the detecting temperature of external temperature sensor 105 is lower than set point of temperature B DEG C (n of step S13), then judge whether to terminate R pattern (step S15).
Being narrowed by the R outlet 32R of control part 102 pairs of three-way valves 11 in step S14, this is the optimization of the decompression amount in order to realize R evaporimeter 5 as described above, to carry out energy-saving operation.
In step S15, control part 102 judges whether to terminate R pattern (step S15), such as, if the detecting temperature of R sensor 106 becomes be less than or equal to R end temp TR2 (such as, 1 DEG C) (y of step S15), then control part 102 judges whether terminate R pattern and be converted to F pattern (step S16).
If the detecting temperature of R sensor 106 for being more than or equal to R end temp TR2 (n of step S15), then returns step S1.
In step s 16, control part 102 judges whether to be converted to F pattern, if the detecting temperature of F sensor 108 starts temperature TF1 (y of step S16) for being more than or equal to F, then in order to be converted to F pattern, control part 102 judges that whether R exports 32R for narrowing state (step S17).
If the detecting temperature of F sensor 108 starts temperature TF1 (n of step S16) lower than F, then return step S1.
R, in order to judge that from R Mode change to F pattern whether R exports 32R for narrowing state (step S17), if narrow state (y of step S17), is then exported 32R standard-sized sheet (step S18) by control part 102.
If it is full-gear (n of step S17) in the state of narrowing that R exports 32R, then return step S3.
In step S18, the R due to three-way valve 11 exports 32R for narrowing state, and therefore control part 102 is set to stipulated time full-gear, to be got rid of by the foreign matter etc. snapped in, returns step S3 subsequently.
(8) effect
According to this example, when will from the state transfer that the outlet of three-way valve 11 is narrowed to other refrigerating modes time, that this outlet is set to stipulated time full-gear, the foreign matter etc. snapped in is got rid of rear transformation, even if be therefore converted to other refrigerating modes and this outlet be set to full-shut position, also positively can close outlet, and not have cooling agent and spill.
(9) modification
In above-mentioned example, when the F of three-way valve 11 being exported 32F under F pattern and narrowing by full-gear, be when the rotating speed of compressor 9 reach the situation that is less than or equal to regulation rotating speed A or outside air temperature reach be more than or equal to set point of temperature B DEG C, but also can be replaced in this, and only compressor 9 rotating speed for be more than or equal to regulation rotating speed A and outside air temperature for being more than or equal to set point of temperature B time, just narrow three-way valve 11 F export 32F.
And, in the r-mode, equally also can only compressor 9 rotating speed for be more than or equal to regulation rotating speed A and outside air temperature for being more than or equal to set point of temperature B time, just narrow R export 32R.
[example 2]
Secondly, the refrigerator 1 of example 2 of the present invention is described according to Figure 10.
Example 2 is with the difference of example 1, as refrigerating mode, R pattern and F pattern can be performed in example 1, and in example 2, except R pattern and F pattern, control part 102 can also perform and make cooling agent flow to R evaporimeter 5 refrigerating mode (hereinafter referred to as " RF pattern ") with both F evaporimeters 4 thus while simultaneously cool Zone R 3 and F district 2, utilizes these 3 kinds of refrigerating modes to perform cooling and operates.
Cooling running as shown in Figure 10, is carry out according to the order of R pattern, RF pattern, F pattern.In rf mode, the R of three-way valve 11 is exported the aperture of 32R and narrow be less than aperture under R pattern, thus the flow path resistance towards R evaporimeter 5 under making RF pattern is greater than the flow path resistance under R pattern.
In addition, control method under R pattern and F pattern is same with example 1, especially when will from F Mode change to R pattern time, when three-way valve 11 F export 32F be not full-gear and for narrowing state, F is exported after 32F is set to stipulated time full-gear in the same manner as example 1, be set to full-shut position and be converted to R pattern.
When will from R Mode change to RF pattern time, when R export 32R for narrowing state, both can directly be converted to RF pattern, and, also again can narrow after being temporarily set to full-gear, thus be converted to RF pattern.
When will from RF Mode change to F pattern time, due under RF pattern R export 32R for narrowing state, therefore after being temporarily set to stipulated time full-gear, be set to full-shut position and be converted to F pattern.
In example 2, even if the R having foreign matter to snap in three-way valve 11 in the implementation of RF pattern exports in 32R, be temporarily set to full-gear due to R is exported 32R, therefore also can get except this foreign matter, R can be exported 32R subsequently and be set to full-shut position.
[example 3]
Secondly, the refrigerator 1 of example 3 of the present invention is described.
In above-mentioned each example, when will from R pattern or RF Mode change to F pattern time, only when the R of three-way valve 11 exports 32R for narrowing state, being temporarily set to full-gear and getting except foreign matter, be set to full-shut position subsequently and be converted to F pattern.
Now, the F of the three-way valve 11 under F pattern exports 32F does not become full-gear because of the rotating speed of compressor 9 sometimes, thus adjusts aperture narrowing under state.
But after other patterns (R pattern or RF pattern) are switched to F pattern, the amount of coolant of F evaporimeter 4 inside can tail off immediately, therefore cooling capacity is not enough.
For this reason, in example 3, when will from other Mode changes to F pattern time, regardless of the rotating speed of compressor 9, all carry out following control, that is, the F of three-way valve 11 is exported 32F and be set to the stipulated time (such as, 1 minute) full-gear, narrows subsequently as the suitable aperture corresponding to the rotating speed of compressor 9.
Thus, in example 3, make after cooling agent spreads all in R evaporimeter 4 fast, the suitable amount of narrowing that the F of three-way valve 11 can be utilized to export 32F cools, therefore, it is possible to contribute to the energy-conservation of refrigerator 1.
In above-mentioned, one embodiment of the present invention is illustrated, but this embodiment is only illustration, is not intended to limit scope of invention.The embodiment of these novelties can be implemented with other various forms, can carry out various omission, replacement, change in the scope of purport not departing from invention.These embodiments or its distortion are included in scope of invention or purport, and comprise in the scope of invention and its equalization recorded in the claims.
