(4) structure of three-way valve 11
According to Fig. 6 the three-way valve 11 in the freeze cycle 50 is described.
As shown in Figure 6, three-way valve 11 has: valve seat 32 is located at the bottom of valve cap (valve case) 31; And valve body 33, be configured in the top of this valve seat 32.
On valve seat 32, be formed with: R exports 32R, cooling agent is flowed out and towards R evaporimeter 5 sides; F exports 32F, cooling agent is flowed out and towards F evaporimeter 4 sides; And inflow entrance 34, cooling agent is flowed into via inlet pipe arrangement 37 from condenser 10.
And, on valve body 33, the distance of counting from rotating shaft 33a is differed from one another and the position of the Zhou Fangxiang that staggers and be formed with R groove 33R and F groove 33F at the lower surface of the heavy wall section 33b of portion.
By stepper motor; Valve body 33 is in this example to rotating predetermined angular with the clockwise direction shown in the arrow K among Fig. 6; Thereby R groove 33R overlaps up and down with F outlet 32F with R outlet 32R or F groove 33F and is communicated with; Perhaps, F groove 33R, R groove 33F all do not overlap with F outlet 32R, R outlet 32F, and F exports 32R, F outlet 32F by 33 sealings of valve body.

(5) electrical structure of refrigerator 1
Secondly, the electrical structure of clear ice case 1 according to the calcspar of Fig. 7.
As shown in Figure 7, set control part 102 comprises micro computer (micro computer) on the control substrate, and is connecting motor, R fan 7, F fan 6, the C fan 18 of compressor 9.
And the door 301a that control part 102 is also connecting refrigerating chamber 301 goes up set external temperature sensor 105, three-way valve 11, R sensor 106, F sensor 108, R evaporator sensor 112, F evaporator sensor 110 on set guidance panel 104, the guidance panel 104.
(6) refrigerating mode
In the refrigerator 1 of said structure; Control part 102 is according to being located at the R sensor 106 in F district 2 or the Zone R 3, the detecting temperature of F sensor 108; Come three-way valve 11 is carried out switching controls; Thereby the freezing refrigerating mode that carry out the refrigeration refrigerating mode make cooling agent flow to R evaporimeter 5 and only Zone R 3 to be cooled off (below, be called " R pattern "), only F district 2 is cooled off with making cooling agent flow to F evaporimeter 4 (below, be called " F pattern ").
(7) operating state of refrigerator 1
Secondly, the operating state of the refrigerator 1 of this instance is described according to the flow chart of Fig. 8 and Fig. 9.
In step S1; Control part 102 judges that whether the detecting temperature of F sensor 108 is predefinedly (for example to begin temperature T F1 more than or equal to F;-18 ℃) (step S1); If for to begin temperature T F1 (for example ,-18 ℃) (that step S1 is (y)) more than or equal to F, then control part 102 begins F patterns (step S3).
Begin temperature T F1 (step S1 not (n)) if be lower than F, judge then whether the detecting temperature of R sensor 106 is to begin temperature T R1 (step S2) more than or equal to R.
If the detecting temperature of R sensor 106 is for to begin temperature T R1 (for example, 4 ℃) (y of step S2) more than or equal to R, the R pattern (step S11) among control part 102 beginning Fig. 9 then.Begin temperature T R1 (n of step S2) if be lower than R, then return step S1.
The rotating speed of compressor 9 is to cooperate the detecting temperature of F sensor 108 to carry out phase inverter (inverter) control.For example, the detecting temperature of F sensor 108 is low more, then reduces the rotating speed of compressor 9 more gradually, and is energy-conservation to realize.
And control part 102 judges whether the rotating speed of compressor 9 is smaller or equal to regulation rotating speed A (step S4), if for smaller or equal to regulation rotating speed A (that step S4 is (y)), then narrow the aperture (step S6) of F outlet 32F.
If be higher than regulation rotating speed A (step S4 not (n)), judge then whether the detecting temperature of external temperature sensor 105 is more than or equal to set point of temperature B ℃ (for example, 27 ℃) (step S5).
For example, if carry out the FREQUENCY CONTROL in the inverter controlling of compressor 9 with 19Hz～70Hz, then corresponding with 28.8Hz rotating speed is corresponding to regulation rotating speed A.
If the detecting temperature of external temperature sensor 105 is more than or equal to set point of temperature B ℃ (for example, 27 ℃) (y of step S5), then control part 102 narrows the aperture (step S6) of F outlet 32F.
If the detecting temperature of external temperature sensor 105 is lower than set point of temperature B ℃ (n of step S5), then judge whether to finish F pattern (step S7).
In step S6, the rotating speed of compressor 9 be smaller or equal to regulation rotating speed or outside air temperature for more than or equal to the B degree, so control part 102 narrows the aperture of the F outlet 32F of three-way valve 11 till 1%～50% (preferred 10%).
And, judge whether to finish F pattern (step S7).Through narrowing F outlet 32F, can make the decompression amount optimization of F evaporimeter 4 inside, thereby can help energy-conservation.
Can optimizedly the reasons are as follows.When the rotating speed of compressor 9 was high, if narrow the aperture of F outlet 32F, then the decompression amount of F evaporimeter 4 can become excessive, thereby can cause the decline of refrigerating capacity or energy-conservation deterioration.
And; When outside air temperature was low, liquefied coolant was stranded in condenser 10 inside more, if therefore narrow the aperture of F outlet 32F; Then the cooling agent of the inside of F evaporimeter 4 can become not enough; Thereby cause the decline of refrigerating capacity or energy-conservation deterioration, so control part 102 do not narrow aperture and is controlled to be full-gear, have only when compressor 9 for smaller or equal to regulation rotating speed A or outside air temperature for more than or equal to B ℃ the time; Control part 102 just narrows F outlet 32F, thereby with the decompression amount optimization of F evaporimeter 4.
In step S7; Control part 102 judges whether to finish the F pattern, for example, if the detecting temperature of F sensor 108 smaller or equal to F end temp TF2 (for example becomes;-22 ℃) (y of step S7), then control part 102 judges whether to finish the F pattern and is converted to R pattern (step S8).If be, then return step S4 more than or equal to F end temp TF2 (n of step S7).
If the detecting temperature of R sensor 106 is for to begin temperature T R1 (y of step S8) more than or equal to said R, then control part 102 is converted to the R pattern, begins temperature T R1 (n of step S8) if be lower than R, then returns step S1.
Then; Control part 102 judges that the F outlet 32F of three-way valve 11 whether for narrowing state (step S9), if be full-gear (n of step S9), then advances to step S11 shown in Figure 9; If, then F is exported 32F and is made as full-gear (step S10) for to narrow state (y of step S9).
At this moment, compressor 9 also is in the low more rotating speed that then reduces more of detecting temperature of R sensor 106, to carry out energy-saving operation.Then, advance to step S12.
Then; Control part 102 judges whether the rotating speed of compressor 9 is smaller or equal to regulation rotating speed A (step S12); If rotating speed is smaller or equal to regulation rotating speed A (y of step S12); Then advance to the step S14 of the R outlet 32R that narrows three-way valve 11,, judge then whether the detecting temperature of external temperature sensor 105 is more than or equal to set point of temperature B ℃ (step S13) if be higher than regulation rotating speed A (n of step S12).
If the detecting temperature of external temperature sensor 105 is more than or equal to set point of temperature B ℃ (y of step S13), then control part 102 advances to the step S14 of the R outlet 32R that narrows three-way valve 11.
If the detecting temperature of external temperature sensor 105 is lower than set point of temperature B ℃ (n of step S13), then judge whether to finish R pattern (step S15).
Narrowing among the step S14 by the R of 102 pairs of three-way valves 11 of control part outlet 32R, this be for the above-mentioned optimization that likewise realizes the decompression amount of R evaporimeter 5, to carry out energy-saving operation.
In step S15; Control part 102 judges whether to finish R pattern (step S15), for example, if the detecting temperature of R sensor 106 smaller or equal to R end temp TR2 (for example becomes; 1 ℃) (y of step S15), then control part 102 judges whether to finish the R pattern and is converted to F pattern (step S16).
If the detecting temperature of R sensor 106 is more than or equal to R end temp TR2 (n of step S15), then return step S1.
In step S16; Control part 102 judges whether to be converted to the F pattern; If the detecting temperature of F sensor 108 is for to begin temperature T F1 (y of step S16) more than or equal to F, then control part 102 judges that in order to be converted to the F pattern whether R outlet 32R is for narrowing state (step S17).
Begin temperature T F1 (n of step S16) if the detecting temperature of F sensor 108 is lower than F, then return step S1.
If R outlet 32R is full-gear (n of step S17) at the state of narrowing, then return step S3.
In step S18, because the R of three-way valve 11 outlet 32R is for narrowing state, so control part 102 is made as the stipulated time full-gear, so that the foreign matter that snaps in etc. is got rid of, returns step S3 subsequently.
(8) effect
According to this instance; When the state-transition that will narrow during to other refrigerating modes from outlet with three-way valve 11; Be that this outlet is made as the stipulated time full-gear, the foreign matter that snaps in etc. got rid of the back change, this outlet is made as full-shut position even therefore be converted to other refrigerating modes; Also can positively close outlet, not spill and do not have cooling agent.
(9) change example
In the above-mentioned instance; When under the F pattern, the F of three-way valve 11 outlet 32F being begun to narrow by full-gear; Be rotating speed at compressor 9 reach reach more than or equal to set point of temperature B ℃ situation smaller or equal to the situation of regulation rotating speed A or outside air temperature under; But also can be replaced in this, and only the rotating speed of compressor 9 be more than or equal to regulation rotating speed A and outside air temperature for more than or equal to set point of temperature B the time, the F that just narrows three-way valve 11 exports 32F.
And, under the R pattern, equally also can be only the rotating speed of compressor 9 be more than or equal to regulation rotating speed A and outside air temperature for more than or equal to set point of temperature B the time, just narrow R and export 32R.
[instance 2]
Secondly, the refrigerator 1 of instance 2 of the present invention is described according to Figure 10.
The cooling running is shown in figure 10, is to carry out according to the order of R pattern, RF pattern, F pattern.Under the RF pattern, narrow the aperture of the R of three-way valve 11 outlet 32R less than the aperture under the R pattern, thereby make under the RF pattern towards the flow path resistance of R evaporimeter 5 greater than the flow path resistance under the R pattern.
In addition; Control method under R pattern and the F pattern is same with instance 1; Especially when will be when the F pattern be converted to the R pattern; At the F of three-way valve 11 outlet 32F is not full-gear and be to narrow under the situation of state, likewise F is exported 32F with instance 1 and is made as after the stipulated time full-gear, is made as full-shut position and is converted to the R pattern.
When will be when the R pattern is converted to the RF pattern, 32R narrows under the situation of state in the R outlet, both can directly be converted to the RF pattern, and, also can after temporarily being made as full-gear, narrow once more, thereby be converted to the RF pattern.
When will be when the RF pattern is converted to the F pattern, because the outlet of the R under RF pattern 32R is for narrowing state, so after temporarily being made as the stipulated time full-gear, is made as full-shut position and is converted to the F pattern.
In instance 2, even in the implementation of RF pattern, there is foreign matter to snap in the R outlet 32R of three-way valve 11,, R temporarily is made as full-gear because being exported 32R, therefore also can get except that this foreign matter, can R be exported 32R subsequently and be made as full-shut position.
[instance 3]
Secondly, the refrigerator 1 to instance 3 of the present invention describes.
In above-mentioned each instance, when will be when R pattern or RF pattern be converted to the F pattern, only at the R of three-way valve 11 outlet 32R when narrowing state, temporarily be made as full-gear and get except that foreign matter, be made as full-shut position subsequently and be converted to the F pattern.
At this moment, 32F is not sometimes because of the rotating speed of compressor 9 becomes full-gear in the F of the three-way valve 11 under F pattern outlet, thereby narrowing adjustment aperture under the state.
But after other patterns (R pattern or RF pattern) switched to the F pattern, F evaporimeter 4 inner amount of coolant can tail off immediately, so cooling capacity is not enough.
For this reason, in instance 3, when will be when other patterns are converted to the F pattern; Regardless of the rotating speed of compressor 9, all carry out following control, promptly; 32F is made as the stipulated time (for example, 1 minute) full-gear with the F of three-way valve 11 outlet, narrow subsequently into the corresponding suitably aperture of the rotating speed of compressor 9.
Thus, in instance 3, make after cooling agent spreads all in the R evaporimeter 4 fast, can utilize the suitable amount of narrowing of the F outlet 32F of three-way valve 11 to cool off, therefore can help the energy-conservation of refrigerator 1.
In above-mentioned, an embodiment of the present invention is illustrated, but this embodiment is merely illustration, be not intended to limit scope of invention.These novel embodiments can be implemented with other various forms, in the scope of the purport that does not break away from invention, can carry out various omissions, replacement, change.These embodiments or its distortion are included in scope of invention or the purport, and are included in the invention of putting down in writing in the claim and its impartial scope.
