Description

  The present invention relates to an elevator with an atmospheric pressure control device, a setting method thereof, and a manufacturing method.

  2. Description of the Related Art Conventionally, elevator air pressure control devices control the air pressure in a car along a preset air pressure pattern in order to reduce passengers' discomfort caused by changes in air pressure that occur at different elevations. As an atmospheric pressure pattern to reduce the discomfort of ear clogging, there is a known method of changing the air pressure in a stepped manner as the elevator moves up and down. There is known a technique for setting the value of the atmospheric pressure change amount to be felt or a value slightly larger than that (see Patent Document 1).

JP-A-7-112879

  Generally, ear clogging caused by a change in atmospheric pressure is recognized as a phenomenon in which the eardrum is deformed when a pressure difference between the middle ear and the outer ear, that is, a pressure difference in the middle ear occurs. It is believed that the greater the middle ear differential pressure, the greater the tympanic membrane deformation, and the greater the feeling of clogging the ears. Therefore, swallowing and removing the ears before the middle-ear differential pressure does not increase eliminates the feeling of ear clogging before discomfort increases. The conventional step-like atmospheric pressure pattern makes the passenger feel clogged at the portion where pressure is increased or decreased, and secures the passenger time for swallowing in the rest period. Thereby, the ears are removed before they become uncomfortable, and the discomfort of the ear clogging is reduced. Further, the conventional two-stage atmospheric pressure pattern makes the passenger feel clogged in the first section, and the ear canal is opened in this section, so that a new feeling of clogging in the passenger occurs in the second section. It is difficult. Thereby, the passenger does not feel the ear clogging again, and the discomfort of the ear clogging is reduced.

  However, since there are individual differences in the size and rigidity of the eardrum, there are large individual differences in the amount of change in atmospheric pressure at which the feeling of ear clogging occurs. When the pressure difference is gradually increased at a predetermined pressure change rate for a plurality of subjects, an ear clogging occurs in a sensitive person with a small change in pressure of about 5 hPa, and about half of the ears are heard at 11 hPa. A clogging sensation occurs, and an ear clogging sensation occurs in almost 100% of people at 24 hPa. As described above, a person who is sensitive to ear clogging causes a feeling of ear clogging with a small amount of atmospheric pressure change. Furthermore, the more sensitive the person, the smaller the amount of change in atmospheric pressure from when the ear clogging occurs until the ear cannot be put up (becomes uncomfortable).

  Therefore, as in Patent Document 1, in the case of the atmospheric pressure pattern matched to the average passenger, there is a possibility that the effect of reducing discomfort may not be obtained because the atmospheric pressure change amount is too large for sensitive passengers. Conventionally, such individual differences have not been fully considered, and the setting of the amount of change in atmospheric pressure taking into account the presence of sensitive passengers has not been sufficiently considered.

  Further, since the ease of occurrence of an ear clogging is different between the case of the ascending operation and the case of the descending operation, it is necessary to take this into consideration when setting the atmospheric pressure change amount.

  From the above, the present invention is equipped with a barometric pressure control device that can effectively induce swallowing, promote ear removal and reduce ear clogging discomfort, considering sensitive passengers who are prone to ear clogging. An object is to provide an elevator, a setting method thereof, and a manufacturing method.

  In order to solve the above problems, the present invention, for example, for each car that moves up and down in a hoistway, discharges air inside the car to the outside and decompresses or fills the car with air outside the car An air volume adjusting device for pressurization, a pressurizing / depressurizing section in which the atmospheric pressure in the car is set to a predetermined atmospheric pressure change rate in accordance with the raising and lowering of the car, and a pause in which the atmospheric pressure change rate is made smaller than the pressurizing / depressurizing section In the method of setting an elevator with a pressure control device equipped with a pressure control device that changes with a pressure pattern having a section, the amount of pressure change corresponding to the incidence of people who clearly feel clogging in the descent operation was shown Based on the first database, the pressure change amount corresponding to the first occurrence rate is set as the pressure change amount in the pressure increasing / decreasing section in the descending operation, and the person who clearly feels clogging in the ascending operation of Based on the second database showing the atmospheric pressure change amount corresponding to the raw rate, the atmospheric pressure change amount corresponding to the second occurrence rate is set as the atmospheric pressure change amount in the pressure increasing / decreasing section in the case of the ascending operation, The pressure change amount in the pressure increasing / decreasing section in the ascending operation is larger than the air pressure change amount in the pressure increasing / decreasing section in the descending operation, and the second occurrence rate is smaller than the first occurrence rate. Value.

  In addition, the present invention uses, for example, a method for setting an elevator with a pressure control device, and the pressure change amount in the pressure increase / decrease interval in the case of descending operation in the pressure control device and the pressure in the pressure increase / decrease interval in the increase operation. It is good also as a manufacturing method of the elevator with the atmospheric | air pressure control apparatus which presets variation | change_quantity.

  In addition, the present invention provides, for example, a car that moves up and down in a hoistway, discharges air in the car to the outside, and decompresses or fills the car with air outside the car and pressurizes the air. An air pressure having an adjusting device, a pressure increasing / decreasing section in which the atmospheric pressure in the car is set to a predetermined atmospheric pressure change rate according to the raising and lowering of the car, and a pause section in which the air pressure change rate is made smaller than the pressure increasing / decreasing section In an elevator with an atmospheric pressure control device having an atmospheric pressure control device that changes according to a pattern, a first database showing an atmospheric pressure change amount corresponding to an occurrence rate of a person who clearly feels clogging in descending operation, and ascending operation And a second database showing an atmospheric pressure change amount corresponding to the incidence of people who clearly feel clogged ears, and the atmospheric pressure control device is configured to generate a first occurrence based on the first database. rate The corresponding atmospheric pressure change amount is set as the atmospheric pressure change amount in the pressure increasing / decreasing section in the descending operation, and the atmospheric pressure change amount corresponding to the second occurrence rate is set in the ascending operation based on the second database. The pressure change amount in the pressure increasing / decreasing section in the ascending operation is larger than the air pressure change amount in the pressure increasing / decreasing section in the descending operation, and The occurrence rate of 2 may be a value smaller than the first occurrence rate.

  According to the present invention, in the atmospheric pressure pattern constituted by the pressure increasing / decreasing section where the atmospheric pressure change rate is large and the resting area where the atmospheric pressure change rate is small, the atmospheric pressure change amount corresponding to the occurrence rate of the person who clearly feels clogged ears is shown. Since the pressure change amount in the pressure increase / decrease section is set based on the database, the pressure pattern can be set in consideration of sensitive passengers who are likely to experience discomfort due to ear clogging. .

It is the figure which expanded one cycle of staircase waveforms.

  Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 1 is an example of a configuration diagram of an elevator with a pressure control device according to an embodiment of the present invention. The elevator with an air pressure control device according to the present embodiment includes an air volume adjusting device 1 composed of a blower, a valve, etc., a car 2, a database 3 showing an amount of change in air pressure corresponding to the occurrence rate of people who clearly feel clogging, and a car. 2 has an atmospheric pressure detection device 4 for detecting the atmospheric pressure in 2 and a control device (atmospheric pressure control device) 5.

  The air volume adjusting device 1 discharges the air in the car 2 that moves up and down in the hoistway to the outside and decompresses or fills the car 2 with the air outside the car 2 to pressurize the car 2. Change the atmospheric pressure. The control device 5 sets an atmospheric pressure pattern in the control device 5 based on the database 3. The control device 5 controls the air volume adjusting device 1 so that the air pressure in the car 2 changes along the atmospheric pressure pattern from the information of the atmospheric pressure detection device 4 and the information of the atmospheric pressure pattern set in the control device 5 in advance. To do. The barometric pressure detection device 4 may be an absolute barometer installed in the car 2 or a differential pressure gauge that measures the pressure difference inside and outside the car 2. In the case of a differential pressure gauge, the external atmospheric pressure at the height position may be estimated from the height information of the car 2, and the absolute atmospheric pressure in the car 2 may be calculated.

FIG. 2 shows the atmospheric pressure pattern 6 with the horizontal axis representing the operating time t and the vertical axis representing the atmospheric pressure P in the car 2. The initial value P ₀ of the atmospheric pressure in the car 2 coincides with the external air pressure at the height position of the car 2 at the start of operation. As shown in FIG. 2, the elevator with the atmospheric pressure control device according to the present embodiment includes a step-like atmospheric pressure pattern 6 including a pressure increasing / decreasing zone 7 having a high atmospheric pressure change rate and a pause zone 8 having a low atmospheric pressure change rate. is there. The provision of the two sections 7 and 8 in this way causes the passengers to feel ear clogging in the section 7 having a large pressure change rate, induces swallowing, swallows the passenger in the section 8 having a low pressure change rate, and removes the ears. Based on the conventional idea of securing time to do. FIG. 2 shows an example of the descent operation, and the atmospheric pressure increases as the car 2 travels. Therefore, in the descending operation, the pressure increasing / decreasing section 7 may be simply referred to as the pressurizing section 7. On the contrary, in the ascending operation, since the atmospheric pressure decreases as the car 2 travels, the pressure increasing / decreasing zone 7 may be simply referred to as the pressure reducing zone 7. The predetermined atmospheric pressure change amount P ₁ generated in the pressurizing section 7 is set based on the database 3 showing the atmospheric pressure change amount corresponding to the occurrence rate of people who clearly feel clogged ears.

  FIG. 3 is a table showing a specific example of the database 3. The database 3 stores column A in which the value of the occurrence rate of people who clearly feel clogging is stored, and the amount of change in atmospheric pressure corresponding to the occurrence rate of people who clearly feel clogging in the descent operation. B column, and C column in which the atmospheric pressure change amount corresponding to the occurrence rate of people who clearly feel ear clogging in the case of ascending operation is stored. That is, this database 3 includes a first database showing the amount of change in atmospheric pressure corresponding to the occurrence rate of people who clearly feel ear clogging in descending operation, and people who feel ear clogging clearly in climbing operation. And a second database showing an atmospheric pressure change amount corresponding to the occurrence rate.

  In the ascending operation, the atmospheric pressure of the car 2 decreases as the vehicle travels, but it is generally known that the pressure change on the decompression side is hardly felt. Therefore, the amount of change in atmospheric pressure corresponding to the incidence of people who clearly feel clogged ears differs between ascending operation and descending operation. In this embodiment, B columns and C columns are provided so that respective values can be set.

  In the present embodiment, an example in which the elevator has the database 3 is described. However, the elevator itself does not have the database 3, and separately maintains a similar database 3 in a server or a maintenance terminal. Based on this database 3, the pressure change in the pressure increasing / decreasing section during the ascending operation and the descending operation is performed. The amount may be obtained in advance, and may be set and stored in advance as a setting parameter for control in the control device 5 at the time of manufacture or maintenance, for example, and the control device 5 may control based on the parameter. .

  Here, the incidence of people who clearly feel clogging of the ears occurs when an atmospheric pressure difference is gradually added at a predetermined atmospheric pressure change rate with respect to a plurality of subjects when the atmospheric pressure change amount increases. It is defined as the cumulative incidence of people who clearly feel clogged ears. For example, 10 subjects are placed in a highly airtight room and gradually pressurized at a pressure change rate of 1.0 hPa / s. If the subject is notified of the timing at which a clear sense of ear clogging has occurred without making ear removal in the middle, data as shown in FIG. 4 can be obtained. 4 shows that when the air pressure change amount reached 6 hPa 6 seconds after the start of the test, the subject No. 4 indicates that a clear sense of ear clogging occurred. At this time, one out of ten people felt clear clogging of the ears, so the incidence is 10%.

  Similarly, after 7 seconds, subject no. 8 indicates that a clear sense of ear clogging occurred. At this time, 2 out of 10 felt clear clogging of the ears, so the incidence is 20%. The amount of change in atmospheric pressure corresponding to an occurrence rate of 20% is 7 hPa. Hereinafter, if data is taken in the same manner, the database 3 of the occurrence rate and the corresponding atmospheric pressure change amount can be created.

  Further, if the timing at which the pressure change becomes uncomfortable enough not to endure the earring is reported, data of the pressure change that becomes uncomfortable can be taken.

  FIG. 5 shows an example of an ear clogging occurrence rate when a plurality of subjects are gradually pressurized at a predetermined pressure change rate. This corresponds to the descending operation. Line 9 shows the incidence of people who clearly feel clogged ears, and line 10 shows the incidence of people who feel clogged ears uncomfortable enough to withstand ear removal. As shown in this figure, sensitive people with low incidences clearly feel clogged with a lower atmospheric pressure change, and the amount of change in air pressure until it reaches an uncomfortable air pressure after clearly feeling clogged ears Is small. On the other hand, when looking at a general subject whose incidence is 50%, the amount of change in atmospheric pressure from when the ear is clearly clogged until it becomes uncomfortable is large. Therefore, a more sensitive person tends to reach an uncomfortable pressure change amount unless he / she removes ears early after clearly feeling clogged. Conversely, a person whose incidence is 55% or more does not reach an unpleasant pressure change amount that cannot be tolerated within the range shown in the graph of FIG. 5 (30 hPa, stroke about 250 m).

From the above, it is considered that a person who hardly feels clogged ears is unlikely to cause discomfort due to clogged ears, and cannot expect the effect of atmospheric pressure control. For this reason, in this embodiment, the optimum atmospheric pressure pattern is set with priority given to sensitive people. Therefore, in the present embodiment, it is desirable to set the atmospheric pressure change amount P ₁ generated in the pressurizing section 7 having a high atmospheric pressure change rate to an atmospheric pressure change amount in which the generation rate of a person who feels clearly is 40% or less. More specifically, it is desirable to set 20% to 40%, and most desirably 20% to 30%. As shown in FIGS. 3 and 5, the set pressure change P ₁ is about 11 hPa when set to 50%, about 9 hPa when set to 40%, about 8 hPa when set to 30%, In the case of setting to 20%, it is about 7 hPa. In this way, by setting the atmospheric pressure change amount P ₁ in the pressurization zone 7 based on the incidence of people who clearly feel clogged ears, the pressurization zone 7 is targeted to sensitive people in consideration of sensitive people. Can clearly cause a feeling of clogging of the ears, and the effect of inducing swallowing can be obtained.

In the case of the present embodiment, the occurrence rate of feeling clear ear clogging is set to 30%, and the atmospheric pressure change amount P ₁ in the pressurizing section 1 is set to 8 hPa. As shown in FIG. 5, when the pressure section 1 reaches 8 hPa, a sensitive passenger whose incidence is 8% or less may become uncomfortable (by removing the ear pressure until the amount of pressure change is reached). Is not in time). In this way, there is a limit to reducing discomfort with the atmospheric pressure pattern, and it may not be possible for passengers who are very sensitive and prone to discomfort, but considering not only line 9 but also line 10 It is also possible to set the occurrence rate in consideration of how much the ratio is allowed. Even in the case where only the line 9 is taken into consideration, the setting can be made in consideration of sensitive persons as compared with the conventional case.

Here, the incidence of feeling clear ear clogging is set to an average of 50% and compared with the case where the pressure change amount P ₁ in the pressurizing section 1 is set to 11 hPa. In this case, there is a possibility that a sensitive passenger corresponding to 18% or less in the pressurizing section 1 becomes uncomfortable. Therefore, the direction in which the occurrence rate is set to 30% and the atmospheric pressure change amount P ₁ in the pressurizing section ₁ is set can cope with passengers that are more sensitive to ear clogging.

As described above, as the atmospheric pressure change amount P ₁ generated in the pressurizing section 7 of the atmospheric pressure pattern 6 is set larger, more people can feel ear clogging, and the effect of inducing swallowing is greater. However, it is a harsh condition for sensitive people who strongly feel clogged ears. For this reason, in the present embodiment, the atmospheric pressure change amount P ₁ in the pressurizing section 7 is set based on the database 3 of the occurrence rate of people who clearly feel clogged ears in consideration of sensitive people.

On the other hand, if the pressure change rate P ₁ ′ in the pressurizing section 7 is too small, it is difficult to generate an ear clogging in the pressurizing section 7 and it is difficult to obtain the effect of inducing swallowing. On the other hand, if the pressure change rate P ₁ ′ in the pressurizing section 7 is too large, the air pressure may suddenly change in the pressurizing section 7 and it may be uncomfortable. Therefore, it is desirable to set the atmospheric pressure change rate P ₁ ′ in the pressurizing section 7 to an appropriate size. Therefore, it was confirmed from the results of the test for general subjects that the range of 1.0 to 2.0 hPa / s is the optimum range as the pressure change rate P ₁ ′ in the pressurization and decompression section 7. In the case of this example, the pressure change rate P ₁ ′ in the pressurizing section 7 was set to 1.3 hPa / s. In addition, since the waveform of the actual atmospheric pressure pattern 6 is rounded and blunted at a portion (bending portion) where the pressurizing section 7 and the rest section 8 are switched, the pressurizing section 7 is determined from the slope (average pressure change rate) excluding that section. Request pressure change rate P ₁ '.

FIG. 6 shows the relationship between the pressure change rate P ₁ ′, the differential pressure 11 that clearly feels clogging, the influence 12 of the ear removal delay time, and the estimated middle ear differential pressure 13 at the time of ear removal.

As shown by the line 11 in FIG. 6, under the condition that the atmospheric pressure change rate P ₁ ′ is large, a feeling of ear clogging occurs with a smaller atmospheric pressure change amount. This tendency was confirmed by a test by a general subject, and the tendency became stronger as the subject became more sensitive. A straight line 12 passing through the origin 0 indicates the influence 12 of the ear removal delay time. The delay time from ear clogging to ear removal is assumed to be 4 seconds, and the differential pressure that increases in 4 seconds is obtained from the pressure change rate P ₁ ′ and is defined as the influence 12 of the ear removal delay time. In the stepped atmospheric pressure pattern, the ear is removed in the resting section 8, and therefore the pressure change rate P ₁ ′ in the resting section 8 is small, so the influence of the strict delay time is smaller than the straight line 12 shown in this figure. . However, it is ignored because it does not interfere with the explanation.

The middle ear differential pressure 13 at the time of the ear removal can be estimated by adding the influence 12 of the ear removal delay time to the pressure difference 11 that causes the ear clogging. Looking at the middle ear differential pressure 13 estimated at this time, the middle ear differential pressure at the time of the ear removal is small and unpleasant before it becomes uncomfortable in the range of an appropriate pressure change rate P ₁ ′. It turns out that it becomes easy. On the other hand, if the atmospheric pressure change rate P ₁ ′ deviates from an appropriate range, it is considered that the middle ear differential pressure 13 when removing the ear increases and the risk of discomfort increases. From tests by general subjects, it has been found that there is an optimum value of the rate of change in atmospheric pressure P ₁ ′ between 1.0 hPa / s and 2.0 hPa / s.

In the case of ascending operation, the atmospheric pressure decreases as the car 2 travels. FIG. 7 shows the occurrence rate of an ear clogging feeling during decompression. Line 14 shows the incidence of people who clearly feel clogged ears, and line 15 shows the incidence of people who feel clogged ears uncomfortable enough to withstand ear removal. It is known from the internal structure of the ear that the pressure change on the decompression side is less likely to feel clogging than the pressurization side. In the case of reduced pressure, it is known that about half of people clearly feel clogged ears when the amount of change in atmospheric pressure is 22 hPa. Therefore, by setting the amount of pressure change that occurs in the decompression section 7 with a high pressure change rate in the range of 9 hPa to 22 hPa, the ears are clearly clogged in the decompression section 7 for about half of the people who are sensitive in ascending operation. An effect of generating a feeling and inducing swallowing is obtained. Therefore, if the occurrence rate at which the ear clogging is clearly felt is set to 50%, the pressure change amount P ₁ in the decompression section 7 is set to 22 hPa from FIGS. In the case of decompression, the ear canal may open naturally around 20 hPa from the structure of the ear canal, and swallowing is induced when the pressure change amount P ₁ in the decompression section 7 is set to a pressure change amount exceeding 20 hPa. In some cases, the ear canal opens naturally before, and the effect of inducing swallowing by pressure control may not be obtained.

  In the present embodiment, since it is difficult to cause an uncomfortable feeling of clogging in ascending operation, the atmospheric pressure pattern is set in consideration of more sensitive passengers. Specifically, referring to FIG. 3 and FIG. 5, based on the first database showing the atmospheric pressure change amount corresponding to the incidence of people who clearly feel clogging in the case of descending operation, The amount of atmospheric pressure change corresponding to the occurrence rate is set as the amount of atmospheric pressure change in the pressure increase / decrease section in the case of descending operation, and the occurrence of people who clearly feel clogging in the case of ascending operation with reference to FIGS. 3 and 7 Based on the second database showing the atmospheric pressure change amount corresponding to the rate, the atmospheric pressure change amount corresponding to the second occurrence rate is set as the atmospheric pressure change amount in the pressure increasing / decreasing section in the ascending operation, and the ascending operation In this case, the pressure change amount in the pressure increase / decrease section is larger than the pressure change amount in the pressure increase / decrease section in the descending operation, and the second occurrence rate is smaller than the first occurrence rate. In this setting method, the control device 5 may set the elevator itself having the database 3 (the first database and the second database), or the elevator itself may set the database 3 (the first database). The pressure change amount obtained by this setting method is set and stored in advance as a setting parameter for control in the control device 5 at the time of manufacturing or maintenance, and control is performed based on that. The apparatus 5 may be controlled.

  In the case of the present embodiment, the first occurrence rate is set to 30% and the atmospheric pressure change amount in the pressurization section is set to 8 hPa. Therefore, the occurrence rate of people who clearly feel clogging in the ascending operation (the second occurrence rate) (Occurrence rate) is set to 10%, and the amount of change in pressure in the decompression section is set to 11 hPa. If the elevator stroke is about 250 m, the amount of change in atmospheric pressure generated by the elevator lift is 30 hPa. Looking at the line 15 in FIG. 7, passengers with an incidence of more than 10% do not experience discomfort that can not withstand ear removal in the range of 30 hPa. Therefore, if the ascending / descending stroke is 250 m, it is considered that passengers corresponding to an occurrence rate of more than 10% do not experience discomfort that cannot withstand ear removal regardless of the presence or absence of atmospheric pressure control.

On the other hand, as shown in FIG. 8, the incidence rate of people who clearly feel clogging of ears is reduced to 10%, the pressure change amount P ₁ in the decompression section 7 is set, and the staircase waveform 6 is repeated to achieve another effect. I can expect. That is, in the first decompression section 7, 10% of passengers feel an ear clogging with a pressure change amount of 11 hPa, but in the second decompression section 7 ′, the total pressure change amount is 22 hPa, so 50% of passengers. Ear clogging occurs, and the effect of inducing swallowing is obtained. In this way, it is possible to prompt the ears of sensitive passengers earlier, without causing a feeling of ear clogging to 50% of the passengers at a time, and the sensitive passengers are less likely to be uncomfortable.

FIG. 9 shows the entire waveform of the atmospheric pressure pattern 6 in the descending operation according to the present invention. The horizontal axis represents the operating time t, and the vertical axis represents the atmospheric pressure change ΔP from the initial atmospheric pressure P ₀ . The atmospheric pressure outside the car 2 changes as shown by the broken line 16 depending on the up / down stroke and the driving speed. When the starting point and the ending point of the broken line 16 are connected, a base pattern 17 serving as a reference for the atmospheric pressure pattern 6 can be drawn. If the start point and the end point of the outside pressure 16 coincide with each other, a curved base pattern 17b and a bent base pattern 17c may be drawn.

In the present embodiment, the pressurizing section 7 and the rest section 8 are repeated at a predetermined cycle of 10 seconds. Since the operating time is not conveniently a multiple of 10 seconds, some sections require time adjustment. In the present embodiment, the first and last sections 18a and 18b are adjusted as the section 18 whose time has been adjusted. The pause section 8 with a small pressure change rate is set to about 4 seconds. About 4 seconds are enough to remove the pressure difference between the inside and outside of the middle ear by removing the ear. The change in atmospheric pressure that occurs in the pause section 2 is set to a level that can be ignored. As a human sensation, there is no difference of about 2 hPa, and an ear clogging occurs when the atmospheric pressure change amount is 5 hPa or more. Therefore, it is a guideline that the atmospheric pressure change amount P ₂ generated in the rest period ₂ is ₂ to 5 hPa or less. To.

  In the case of the present embodiment, the waveforms of the sections 18 a and 18 b adjusted for time are waveforms along the base pattern 17. It should be noted that the partial time adjustment may be eliminated by setting the same period for the entire operation time, or the time may be adjusted in the central portion. Further, the staircase waveform may be set to a different waveform for each period, or only a part of the first half or the second half may be a staircase waveform. In any case, in the staircase waveform composed of a portion having a large pressure change rate and a small portion, the pressure change amount in the pressure increasing / decreasing section 7 is set based on the database 3 of the occurrence rate of persons who clearly feel ear clogging. The effects of the invention can be obtained.

  By the way, if ear clogging is felt in the first pressurizing section 7, the middle ear differential pressure is eliminated, and the pressure difference inside and outside the middle ear returns to zero. In the second pressurizing section 7, ear clogging is felt again, and the ear removal is repeated in the same manner, so that the ear removal is performed before the middle ear differential pressure becomes unpleasantly increased, and the discomfort is reduced. In addition, after the second time, the air pressure may get used to, and the ears may not be regularly removed.

  In this embodiment, the atmospheric pressure pattern 6 is formed with the first half along the lower side of the base pattern 17 and the second half along the upper side of the base pattern 17. Looking at the portion of the atmospheric pressure pattern 6 along the lower side of the base pattern 17, the start position of the rest section 8 and the end position of the pressurization section 7 are arranged so as to coincide with the base pattern 17. In actual atmospheric pressure control, the waveform of the bent portion where the pressurizing section 7 and the rest section 8 are switched becomes dull. Therefore, the actual bending point of the atmospheric pressure pattern 6 does not always exactly match the base pattern 17.

FIG. 10 is an enlarged view of the atmospheric pressure pattern 6 and the base pattern 17 having a staircase waveform for one cycle while omitting the blunting of the bending point as described above. When the operation speed is about 350 m / min, the inclination of the base pattern 17 is 0.7 hPa / s. As shown by the solid line 6, when the time of the pressurizing section 7 and the rest section 8 is given equally for 5 seconds, the pressure change rate P ₁ ′ of the pressurizing section 7 becomes 1.4 hPa / s. In this case, the atmospheric pressure change rate P ₁ ′ in the pressurizing section 7 falls within an appropriate range of 1.0 to 2.0 hPa / s. However, when the operation speed is about 560 m / min, the inclination of the base pattern 17 increases to 1.1 hPa / s. As shown by the solid line 6, when the time of the pressurizing section 7 and the rest section 8 is given equally every 5 seconds, the pressure change amount P ₁ generated in the pressurizing section 7 becomes 11 hPa. When the incidence rate of people who clearly feel clogging of ears is set to 30% and the pressure change amount P ₁ in the pressurization zone 7 is set to 8 hPa, the pressure change amount P ₂ in the rest zone 8 is set as shown by the broken line 19. The pressure change amount P ₁ generated in the pressurizing section 7 is adjusted to 8 hPa.

Moreover, as shown by the solid line 6, when the time of the pressurizing section 7 and the rest section 8 is given equally for 5 seconds, the pressure change rate P ₁ ′ of the pressurizing section 7 becomes 2.2 hPa / s, and the appropriate pressure The range of change rate is exceeded. Therefore, since it is sufficient that the rest section 8 is 4 seconds, as shown by the broken line 20, the pressurization section 7 is extended to 6 seconds, and the pressure change rate P ₁ ′ of the pressurization section 7 is set to 2.0 hPa / s. What is necessary is just to make it reduce to the following 1.8 hPa / s.

  Then, in the control device 5, the time distribution between the pressurizing section 7 and the rest section 8 and the setting of the atmospheric pressure change amount between the pressurizing section 7 and the rest section 8 are set in the control device 5 so as to be within the range of the appropriate pressure change rate. It may be set by calculation.

  The embodiments of the present invention have been described above. However, the configurations described in the embodiments so far are only examples, and the present invention can be appropriately changed without departing from the technical idea.
