(implementation method 2)
Fig. 8 A are the cross-sectional top views of the state of generally closing the door of the freezer refrigerating chamber of the utility model implementation method 2.Figure
8B is the side cross-sectional, view of the state of generally closing the door of the freezer refrigerating chamber.Fig. 9 A are to housing side by the freezer refrigerating chamber door
The cross-sectional top view of the state of closing the door of traction.Fig. 9 B be by side from the freezer refrigerating chamber door to the state of closing the door of housing side-lining
Depending on sectional view.
Below, as the control of the testing result according to human body sensing sensor 18 that was illustrated in implementation method 1
One, the function to being drawn door using actuator is illustrated.Wherein, for the mutually isostructural part of implementation method 1, use
Same-sign is simultaneously omitted the description.
The receiver 42 supported by framework 41 is installed in the refrigerating chamber door 15a of refrigerating chamber 15.In addition, in refrigerating chamber door
The pull orbit portion of 15a, in order to reliably close the door, be provided with by lockable mechanism from refrigerating chamber door 15a to the side-lining of housing 40 1
43.In addition, in order to prevent clearance leakage of the cold air from refrigerating chamber door 15a and housing 40, be provided with by resin material formed it is close
Packing 44.
The gap γ of housing 40 and refrigerating chamber door 15a, because of the size difference of part and assembling difference that are constituted, at each
Do not fixed in freezer, so make sealing gasket 44 that there is elasticity, using the value bigger than designed gap size.Thus, it is close
Packing 44 is turning into slightly compressed state at closing time.
More (closing the door) tractive force of enhancing lockable mechanism 43 and compression seal pad 44 strongly, housing 40 is with sealing gasket 44 just
More it is close to, it is possible to increase the thermal insulation of refrigerating chamber 15.On the other hand, it is necessary to big enabling power, the small old man of strength and child have
Freezer door possibly cannot be opened.Therefore, the tractive force of lockable mechanism 43 is suppressed less than 50N, enabling to comparing
Weak power opens refrigerating chamber door 15a.In addition, sealing gasket 44 also has the leeway being further compressed.
Actuator 45 is made up of motor and gear mechanism etc..Its power is delivered to rotary shaft 46 by actuator 45, makes arm
47 rotate.Alternatively, it is also possible to replace motor using other driving sources such as solenoid.
Framework 41 is provided with axis of traction 48.When arm 47 is rotated, axis of traction 48 is located at the position abutted with arm 47.That is,
The action of arm 47 can be delivered to refrigerating chamber door 15a by axis of traction 48.
Below, using the control flow chart shown in Fig. 8 A, Fig. 8 B, Fig. 9 A, Fig. 9 B and Figure 10, to what is constituted in the above-described manner
The action of freezer is illustrated.
In an initial condition, actuator 45 makes arm 47 stop at the position shown in Fig. 8 A.Using the state as reference position.
Now, arm 47 is independent of each other with axis of traction 48, so refrigerating chamber door 15a is free to opening and closing.Refrigerating chamber door 15a is born by locking
Effect from locking mechanism 43 to the side-lining of housing 40 1.But, as described above, in order to suppress enabling power, the tractive force of lockable mechanism 43
Using certain following power.Therefore, in the freezer of present embodiment, sealing gasket 44 also has the leeway being further compressed.
But, if the possibility that user is not opened and closed on freezer periphery, refrigerating chamber door 15a, so need not
Suppress enabling power.Therefore, refrigerating chamber door 15a is drawn strongly to the side of housing 40, can fully compression seal pad 44, carry
Thermal insulation high.
Then, using human body sensing sensor 18, according to certain hour detection freezer periphery whether someone's (step
101).If more than certain hour not detecting people's (being Y in step 101), judge that refrigerating chamber door 15a will not temporarily be beaten
Open.Then, actuator 45 is powered, by refrigerating chamber door 15a strongly to the side-lining (step 102) of housing 40 1.
Now required tractive force is according to the elastic of sealing gasket, the friction of the pull track of refrigerating chamber door 15a and refrigerating chamber
Food weight in 15 etc. and change.The power of general 50N~300N is the power for being capable of abundant compression seal pad.The compression is to pass through
Cursor 47, makes it be abutted with axis of traction 48 as shown in Figure 9 A, and refrigerating chamber door 15a is applied force to the direction of housing 40 to realize
's.Thus, housing 40 reduces with the gap beta of refrigerating chamber door 15a compared with the gap γ of Fig. 8 A, and sealing gasket 44 is from original thickness
By compression more than 10%.
Sealing gasket 44 can further be compressed by using soft material and reduction material thickness etc..Thus, with it is outer
The contact area of portion's air is reduced, it is possible to expecting the raising of thermal insulation.Now, it is also possible to expect to suppress the compression of sealing gasket
The tractive force of required actuator.
In addition, in order to improve the close property with housing, it is in sealing gasket to include magnet more.But, in the present embodiment, because
The tractive force of actuator 45, close property is very high, even if so no magnet also has no problem.Therewith, be not in because of magnetic
The heat loss that the heat transfer of iron causes, it is possible to further improving thermal insulation.
In addition, the temperature of cold air is more low more flows to lower section, so sealing gasket 44 is also the following side for compressing refrigerating chamber door 15a
The mode divided can more effectively improve thermal insulation.Therefore, in the present embodiment, the lower surface in refrigerating chamber 15 sets actuating
Device 45, the downside of main traction refrigerating chamber door 15a.
Compression seal pad 44, after refrigerating chamber door 15a is fully close to housing 40, stopping is powered to actuator 45.But,
Since it is designed that also produced under the conditions of cold that moment of torsion is kept using the motor 24 and gear mechanism inside actuator 45,
So the traction state of Fig. 9 A is maintained (step 103).Additionally, the state in order to keep Fig. 9 A in the case of cold,
Can also be using the mechanism locked in the transmission mechanism of motor 24 to arm 47.For example, it is also possible to using make spring mechanism or
The mechanism that second motor mechanism is disturbed and locked with gear.
If sealing gasket 44 is fully close to housing 40, the thermal insulation of refrigerating chamber 15 is improved, can suppress cold air to
External leakage.Therefore, it is possible to reduce the cooling systems 26 such as compressor 27, cooling fan 28, air quantity damper 29 shown in Fig. 2
Consumption electric power.Also, because actuator 45 is also not powered on, it is possible to reducing the consumption electric power of freezer.
The state for improving the thermal insulation is continued until that people comes freezer periphery next time.In human body sensing sensor 18
Detect in the presence of people (Y in step 104), refrigerating chamber door 15a is possible to be opened and closed.Therefore, in order to compared with
Weak power opens refrigerating chamber door 15a, it is necessary to make the reference position that arm 47 is rapidly returned to Fig. 8 A.Now, actuator 45 make arm 47 to
The direction opposite with step 102 rotates, within presence to the time (3 seconds degree) for opening refrigerating chamber door 15a for detecting people,
Arm 47 is set to return to reference position (step 105).The action of the step 101 to step 105 is the elemental motion of present embodiment.
In a step 101, when detecting the presence of people, arm 47 maintains the reference position of Fig. 8 A.Now, using being arranged at cause
Reference position detecting part 25 in dynamic device 45 differentiates whether arm 47 is located at reference position (step 106).Just in case because of originals such as positional deviations
Because of arm 47 not in the case of reference position (N in step 106), enter to exercise the action (step 107) that arm 47 returns to reference position.It is logical
Crossing the location action can suppress the rotation error of arm 47, it is advantageous to also implement the location action when power supply etc. is accessed.
As described above, in the present embodiment, when people can not possibly use freezer, being drawn strongly using actuator 45
Refrigerating chamber door 15a, improves thermal insulation.In addition, when people is possibly used freezer, weaken the traction of refrigerating chamber door 15a, can
Suppress enabling power.
On the other hand, in said structure, for example, when when having a power failure, arm 47 is in the state of Fig. 9 A, that is, making one positioned at cold
Zang Ku peripheries, cannot also make arm 47 return to reference position.That is, power failure when be possible to that refrigerating chamber door 15a cannot be opened.Therefore, cause
Dynamic device 45 is designed to, if applying external force slightly strong when being acted than sliding door, arm 47 can return to reference position.The structure is logical
Crossing makes the mechanism of the occlusion of gear using clutch mechanism or with the external force more than certain to realize.
Like this, user carries out opening door operation by with slightly strong power to refrigerating chamber door 15a, even if also can when having a power failure
Hold mode is released, refrigerating chamber door 15a is opened.Alternatively, it is also possible to set by from vegetable compartment 16 or outside freezer 11
The hand lever operation in portion etc. makes arm 47 return to the mechanism of reference position.
Like this, when user not when, compression seal pad, improve receiving room thermal insulation, improve energy saving.In addition,
When user is located at freezer periphery, slow down the compressive state of sealing gasket, when suppress enabling power close the door state when, with lighter
Power can just open door, can take into account and realize thermal insulation and enabling.
In addition, present embodiment is illustrated to refrigerating chamber 15, it is also possible to suitable for other receiving rooms.
As described above, in the freezer 11 of present embodiment, when human body sensing sensor 18 detects people, computing control
Weaken the tractive force of refrigerating chamber door 15a in portion processed 21.Thus, refrigerating chamber door 15a can just be opened with lighter power.
(implementation method 3)
Below, as the control of the testing result according to human body sensing sensor 18 that was illustrated in implementation method 1
One, to judging that user does not exist, the power saving function for suppressing cooling capacity is illustrated.
The detection range of human body sensing sensor 18 covers in kitchen substantially, it is possible to it is cold to judge whether user is located at
Hide the state on the periphery of storehouse 11.
For example, in breakfast, date for dinner and its preparing cooking time, user is located at including the kitchen including freezer 11
In space, so being able to detect that the presence of people using human body sensing sensor 18.In addition, in outgoing time and the late into the night etc., people
Not in the vicinity of freezer 11, so being able to detect that people does not exist using human body sensing sensor 18.Using these functions, when making
User not state continue it is certain during when, change the operating condition of cooling system 26, freezer 11 enters economize on electricity and operates.Separately
On the one hand, when human body sensing sensor 18 detects the presence of user on the periphery of freezer 11, and the state to continue one regular
Between when, release economize on electricity operating.
In existing freezer, if user cannot deliberately not release economize on electricity operating if operation button.Therefore, door
Opening and closing is more, and the state not being sufficiently cooled is become in storehouse.Thus, the temperature of food is raised sometimes, is preserved state and is deteriorated.
But, in the freezer 11 of present embodiment, when the existence time for being judged as user, release economize on electricity fortune
Turn, carry out the cooling under generally operating.That is, predict that be susceptible to a situation for opening and closing is sufficiently cooled in advance, so energy
Enough keep the keeping quality of food.
As described above, by the detection of human body sensing sensor 18, when user is not or not freezer periphery, door opening and closing causes
Storehouse temperature when raising few, can automatically carry out economize on electricity operating.
As described above, in the freezer 11 of present embodiment, when the certain hour of human body sensing sensor 18 is not detected by
During people, calculation control unit 21 makes freezer 11 enter economize on electricity operating.Thereby, it is possible to reduce the consumption electric power of freezer 11.
