When stop position, correction portion 50d revises decision threshold α 1 according to the difference degree of input level and the above-mentioned default value α 1 of above-mentioned analog/digital conversion port 50b ", to set the decision threshold among the above-mentioned identifying unit 50x.

Therefore, need not for correction temporarily to stop the lifting action of draining rack 2, need not to set in addition the time that is used to revise.In addition, set the threshold value that is used for foreign matter contact judgement owing to the range with draining rack 2 is divided into a plurality of intervals, so the capacity storage that it can be less is in storage part 50c.

The 4th embodiment

Figure 15 is the flow chart of the variation that is used for a reference value that foreign matter detects that is used to illustrate the kitchen cabinet of another embodiment of the present invention.Also can adopt above-mentioned structure shown in Figure 12 in the kitchen cabinet of present embodiment, only calculate correction portion 50d and the structure of storage part 50c and the part difference of action of treatment circuit 50.What should gaze at is in the present embodiment, as mentioned above, when elevating mechanism 6 makes draining rack 2 toward deposit position that is lower position decline, to utilize to stop near near the position this point lower limit of above-mentioned lower position and carries out the change of said reference value.Particularly, as shown in figure 14, even the position is as the reference position near the above-mentioned lower limit that the variation that position deviation static capacity is a little arranged is also less, when draining rack 2 descends and stop near this lower limit the position, deposit the input level of above-mentioned analog/digital conversion port 50b in storage part 50c as the said reference value, correction portion 50d tries to achieve decision threshold by above-mentioned amplitude of variation Δ V1 is added in this a reference value.

In addition, what should gaze at is, when stopping in other positions, the input level of the above-mentioned analog/digital conversion port 50b of this position deposits 50c in as the said reference value, correction portion 50d tries to achieve decision threshold by add above-mentioned amplitude of variation Δ V1 to this a reference value, and, when stopping in this position for a long time, also revise, with the variation of corresponding environment delicate variations such as (temperature, humidity, article) picking and placeing by upgrading the said reference value.This upgrades also not the absolute value according to static capacity, and is based on variable quantity, feeds back to a reference value with the variation as a whole of this variable quantity and carries out.

The a reference value that correction portion 50d carried out that Figure 15 is illustrated in other positions stops time calculation treatment circuit 50 is new element more.At step S1,, judge whether in stopping according to the output of above-mentioned swept resistance 45, when in moving the time,, respectively the counter of descent direction and the counter of ascent direction are resetted at step S2, S3, at step S4, the said reference value is made zero, and return above-mentioned steps S1.

On the other hand, at above-mentioned steps S1, when draining rack 2 moves to step S11, and reads the data from above-mentioned analog/digital conversion port 50b when middle for stopping, at step S12, judge a reference value that has or not when stopping, when a reference value also is not read, at step S13, a reference value is set at present value, returns above-mentioned steps S1.

In addition, at above-mentioned steps S12, a reference value when stopping is set, then move to step S14, relatively from the data of above-mentioned analog/digital conversion port 50b and a reference value of this storage, at step S15, if then represent not take place above-mentioned environmental change with respect to a reference value no change, therefore at step S16, S17, respectively the counter of descent direction and the counter of ascent direction are resetted, and return above-mentioned steps S1.

Relative therewith, at step S15, if change with respect to a reference value, then move to step S21, whether the value of judging this time is greater than a reference value, if greater than a reference value, then move to step S22, the counter of above-mentioned descent direction is resetted, and at step S23, the counter of ascent direction is counted action, at step S24, judge that whether count value surpasses predetermined value, when not surpassing, returns above-mentioned steps S1.At above-mentioned steps S24, when count value surpassed predetermined value, the above environmental change of above-mentioned predetermined value had taken place in statement, static capacity increases, at step S25, predetermined difference value is added in a reference value of storage part 50c storage, upgrade and return above-mentioned steps S1 at step S26.

Among the above-mentioned steps S21, if when the value of this time is lower than a reference value, move to step S32, the counter of above-mentioned ascent direction is reset, at step S33, the counter of descent direction is counted action, at step S34, judge that whether count value surpasses predetermined value, when not surpassing, returns above-mentioned steps S1.At above-mentioned steps S34, when count value surpassed predetermined value, the above environmental change of above-mentioned predetermined value had taken place in expression, static capacity reduces, at step S35, deduct predetermined difference value from a reference value of storage part 50c storage, upgrade and return above-mentioned steps S1 at step S36.

Adopt said structure, in cabinet 1, storage part 50c does not need to store in advance above-mentioned default value α 1, and any stop position beyond can be in the reference position carries out the correction at individual difference and environmental change, detects foreign matter accurately.In addition, whenever carry out once back and forth, must utilize in the said reference position to stop this point, at this moment, correction is made zero, and input reference again, therefore, cabinet 1 can detect foreign matter more accurately at draining rack 2 toward sandwiching the high lifting lower position of possibility when descending.In addition, cabinet 1 is set near the position above-mentioned lower limit that temporarily stops when descending by the reference position that will be used for a reference value correction, then need not to set in addition the correction time can revise.

The 5th embodiment

Figure 16 is the system diagram that the foreign matter in the kitchen cabinet of another embodiment of the present invention detects, and Figure 17 is the control box 40 of expression Figure 16 " in relate to the block diagram of circuit structure of the transducing part of draining rack 2 liftings.System in the present embodiment and control box 40 " be similar to system shown in above-mentioned Figure 11 (a) and control box 40 ' shown in Figure 12 respectively, so the identical reference marks of counterpart use, and omit its explanation.

The control box 40 of present embodiment "; also be connected; what should gaze at is in the present embodiment, control box 40 with above-mentioned swept resistance 45 and Photo Interrupter 46 " in calculation treatment circuit 50 " also detect sandwiching of foreign matter according to rising or falling speed by the measured draining rack 2 of above-mentioned swept resistance 45.Calculation treatment circuit 50 " detection unit 50y, when having detected foreign matter when sandwiching, promptly stop motor 20, the lifting of draining rack 2 is stopped, and sandwiches notice/7e of warning portion by above-mentioned foreign matter and notify the user.In addition, by above-mentioned swept resistance 45, above-mentioned detection unit 50y detects the overload of draining rack 2, is notified by above-mentioned overload notification/7f of warning portion.

Particularly, calculation treatment circuit 50 " storage part 50c " in store the 1st value that is variation delta V1, as the threshold value that sandwiches of judgement foreign matter.Above-mentioned variation delta V1 be with draining rack 2 based on the corresponding variable quantity of the lifting amount of above-mentioned elevating mechanism 6 in scheduled unit time Δ t from the input level of above-mentioned swept resistance 45 input analog/digital conversion port 50a, the threshold velocity that foreign matter sandwiches is judged in expression.

This calculates treatment circuit 50 " in detection unit 50y; when the actual input level that reads analog/digital conversion port 50a; according to and above-mentioned storage part 50c " in poor between the input level before the above-mentioned unit interval Δ t of storage in advance, try to achieve variation delta V, as this variation delta V during less than above-mentioned variation delta V1, judging has foreign matter to sandwich, and stops elevating mechanism 6, and sandwiches notice/7e of warning portion by above-mentioned foreign matter and notify the user that the foreign matter existence is arranged.Therefore, above-mentioned swept resistance 45 constitutes the speed test section, and detection unit 50y and foreign matter sandwich notice/7e of warning portion and constitute foreign matter detection notice unit, and in addition, detection unit 50y constitutes foreign matter and detects the portion that stops.

Therefore, remove foreign matter etc., can prevent to pin and to operate or overload problems such as (overcurrents) because of sandwiching elevating mechanism 6 that foreign matter causes by the user who obtains above-mentioned notice.

In addition, there is foreign matter to sandwich, just after elevating mechanism 6 is stopped, this elevating mechanism 6 reversed, so that the predetermined height of draining rack 2 liftings if above-mentioned detection unit 50y judges.In a single day thus, even sandwich foreign matter, also can eliminate this problem by reversing, the user can remove above-mentioned foreign matter easily.

In addition, above-mentioned storage part 50c " in also store the 2nd value that is variation delta V2 greater than above-mentioned variation delta V1; the variation delta V when rising is during less than above-mentioned variation delta V2, and above-mentioned detection unit 50x is judged to be overload, notifies the user by above-mentioned overload notification/7f of warning portion.Therefore, above-mentioned detection unit 50y and overload notification/7f of warning portion constitutes the overload notification unit.Therefore, not only can tackle foreign matter and sandwich problem, can also tackle the overload problem.
