Firstly, the structure on clamshell doors trigger device 113 and its periphery is illustrated referring to Fig. 7.Heat-insulated 109 He of demarcation plate Vegetable compartment door 106a is in order to ensure air-tightness and absorbs impact of closing the door, and via gasket maintenance distance E (not shown) and maintains door Closed state.In the present embodiment, operation transfer part 115 has protrusion.In addition, use is by setting in operation transfer part 115 The rigid body part of the compositions such as rouge molded product.In addition, in the present embodiment, operation transfer part 115 is utilized for ensuring air-tightness Gasket caused by stress and the first electricity for being set to the opposite position of operation transfer part 115, aftermentioned test section 114 It is close to pole 127.

In addition, door open and-shut mode test section 125 detects the door closure state of vegetable compartment door 106a.Door open and-shut mode test section 125 generally become one using magnetic substances such as magnet in the Magnetic Sensors such as Hall IC in heat-insulated demarcation plate 109 and vegetable compartment door 106a To the electronic type test section of composition.But door open and-shut mode test section 125 is not limited to the structure, if heat-insulated demarcation plate 109 The distance between vegetable compartment door 106a is distance E or more, can also be disconnected by contact and the machine apart from engagement contacts when becoming E The switch of tool formula is constituted.

In addition, in the present embodiment, using inductosyn 131 in test section 114.The detection of test section 114 comes from Operate the stress of transfer part 115.Inside inductosyn 131, first electrode 127 and second electrode 128 are by metal Torsionspring 126 can be connected movably.First electrode 127 and second electrode 128 are electric with other frequency detecting portion 130 respectively Connection.In addition, first electrode 127, torsionspring 126 and second electrode 128 are connected in series, first electrode 127, not with It is electrically connected between one end that torsionspring 126 connects and second electrode 128, one end for not connect with torsionspring 126 Capacitor 129.When the protrusion for operating transfer part 115 is pushed by stress, first electrode 127 is mobile, with the second fixed electricity Torsionspring 126 between pole 128 is compressed, and by reducing the overall length of torsionspring 126, makes the inductance value of torsionspring 126 Become larger.

Control circuit substrate 122 has power supply unit 123 and control unit 124.Power supply of the electric power S4 from control circuit substrate 122 Portion 123 is supplied to frequency detecting portion 130.In addition, sending control circuit substrate for the signal S5 that frequency detecting portion 130 detects 122 control unit 124.In addition, input is about door open and-shut mode test section from door open and-shut mode test section 125 to control unit 124 The signal S6 of the 125 door open and-shut modes detected.

About freezer 200 configured as described above, hereinafter, using Fig. 8 shows inductosyn output time sequence The action flow chart of the curve graph and Fig. 9 that arrange variation is acted to it and effect is illustrated.

Firstly, in step 9, when supplying power supply to freezer 200 under vegetable compartment door 106a door closure state, control electricity Base board 122 is started to work, and supplies electric power S4 from power supply unit 123 to the frequency detecting portion 130 of inductosyn 131.At this point, Inductosyn 131 forms resonance circuit by the inductance of torsionspring 126 and the capacitor of capacitor 129, and resonance frequency f is Formula (1).

(formula 1)

In formula 1, L is the inductance value of torsionspring 126, and C is the capacitance of capacitor 129, and is all fixed value.

In frequency detecting portion 130, resonance frequency f is scaled L value using formula (1), using the L value as signal S5, frequency Signal S5 is output to control unit 124 by rate test section 130, (the h) at the time of Fig. 8 that enters step 10.

Then, in step 10, door open and-shut mode test section 125 detects the open and-shut mode of vegetable compartment door 106a to judge to be No is door closure state.In the case where being judged as shutdown, signal S6 is output to control unit by door open and-shut mode test section 125 124, enter step 11.In the case where being judged as enabling, signal S6 is output to control unit by door open and-shut mode test section 125 124, it carries out in step 10 standby.In addition, if being door closure state, then by stress caused by gasket, induction type is passed The torsionspring 126 of sensor 131 via operation transfer part 115 protrusion be pushed into and compressed, from and its overall length shorten, inductance Value than initially becomes larger, and is output into L2 (referring to Fig. 8).This is because the spy of the relational expression usually in disc spring with formula (2) Property, so if it is identical the number of turns, its shorter inductance value of overall length more becomes larger to ratio (i) at the time of Fig. 8.

(formula 2)

In formula (2), μ is magnetic conductivity, N is the number of turns, d is coil diameter and l is coil overall length.

In a step 11, control unit 124 judges that vegetable compartment door 106a for door closure state, is received from frequency detecting portion 130 Signal S5, and store output valve L2, the (i~moment j) at the time of Fig. 8 that enters step 12.

Then, in step 12, control unit 124 measures the output valve L3 of inductosyn 131, enters step 13.

In step 13, control unit 124 judges whether the difference of output valve L3 and output valve L2 reach prespecified output Value difference Δ L.If reach output value difference Δ L, control unit 124 be judged as vegetable compartment door 106a from usual door closure state by with Family is pushed further into, and enters step 14.Otherwise, control unit 124 return to step 12, it is standby to have opening door operation (Fig. 8 when Carve j~moment m).

It here, in fig. 8, be more than L3 (as variation delta L) in the output valve of moment l inductosyn 131 is straight The influence in evening time of vegetable compartment door 106a is cut off to user.In addition, user leaves hand from vegetable compartment door 106a after the activation At the time of m, it is the spring constant of torsionspring 126 and the bullet of gasket that output valve, which does not return to L2, becomes the L1 for having several variations, Lagging influence possessed by property body.Therefore, the freezer 200 of present embodiment is configured in the opening door operation after next time more The output valve L2 of new usually door closure state.

At step 14, the signal S5 from inductosyn 131 is inputted to control unit 124 and come from door open and-shut mode The signal S6 of test section 125, control unit 124 judge door open and-shut mode, are determined as having opening door operation, enter step 15 (Fig. 8 when It carves m).

Here, by when not being to be pushed into vegetable compartment door 106a by user but the hand of user leaves from vegetable compartment door 106a M (control unit 124 determines that there are when opening door operation) is used as opening door operation at the time of moment l is into step 14, is because will not band Come the incongruity acted.

Then, in step 15, the control unit 124 of control circuit substrate 122 is judged as that an opening action starts, and opens door The movement of closing part 116 (f) at the time of Fig. 8, and confirm that vegetable compartment door 106a is door open shape by door open and-shut mode test section 125 State, back to step 10 (n) at the time of Fig. 8.

As described above, the test section that there is the freezer 200 of present embodiment detection to be built in enabling trigger device 113 The inductosyn of the inductance value of 114 torsionspring 126.In addition, the operation transfer part of the freezer 200 of present embodiment 115 have protrusion.Rigid body part is used in operation transfer part 115.

In addition, the freezer 200 of present embodiment is configured to the vegetable compartment door 106a in drawing and pulling type from door closure state quilt When pressing, its stress transfer to test section 114 is compressed torsionspring 126 by operation transfer part 115.According to this structure, can The case where variation detection of inductance value based on torsionspring 126 has been pushed into vegetable compartment door 106a by user, determines whether enabling Operation.In addition, according to this structure, can judge that door is pushed into reliable numerical value apart from displacement.Therefore, according to this Structure, because the dispersion bring deviation of the power such as stress mornitoring, can be avoided to bring to the operation feeling of user and not assist Adjust sense.
