Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Before describing an air conditioner and a detection control device and method for moving parts in the air conditioner according to an embodiment of the present invention, a door panel sticking detection technique in the related art will be briefly described.

The related art provides a sliding door detection control device, wherein a grating strip is additionally arranged on a door plate, a light emitting tube and a light receiving tube are respectively additionally arranged on two sides of the grating strip, a high-low level pulse feedback signal is generated by the interval light transmission of the grating strip when the door plate normally moves, and whether the door plate is clamped or not can be monitored by detecting the duration time of the high level or the low level.

The related art also proposes a sliding door detection control device, in which whether the door panel is stuck is detected by an impedance detection circuit, using the principle that an inductance value changes to cause a parallel circuit impedance change after an inductor and capacitor parallel resonance circuit clamps an obstacle.

For the detection control device in the first related art, the light emitting tube and the light receiving tube are respectively arranged on two sides of the grating, the structure is complex, the difficulty is high, and a certain gap is needed between the grating and the door panel. In addition, due to the adoption of the photoelectric principle, in order to avoid multiple factors such as ambient light interference, the light transmission and shading gaps of the grating cannot be too narrow, so that the duration time of high and low levels of feedback pulses is prolonged, the detection time of clamping stagnation is prolonged, the detection sensitivity is reduced, and pain can be sustained for a long time if fingers are clamped, so that the user cannot accept the feedback pulses.

For the detection control device in the second related art, the inductor used in the parallel circuit is a metal sheet with copper foil routing, the change of the inductance value is caused by the deformation of the metal sheet caused by an obstacle when the door panel is clamped, but the metal sheet is seriously extruded each time the door panel is closed, although the detection function is closed without the obstacle, the false detection cannot be caused, but the metal sheet is still seriously deformed, and the unrecoverable deformation or complete damage can be caused to the metal sheet after the detection control device is repeatedly closed, so that the service life of the device is limited, and the detection function is likely to fail after the operation time is prolonged. Moreover, the device is only suitable for a single-side door opening and closing device, cannot be used for a double-side door opening and closing device, is only suitable for clamping stagnation in the closing process, and cannot detect clamping stagnation in the opening process.

Based on the above, the embodiment of the invention provides an air conditioner and a detection control device and method for a moving part in the air conditioner.

The following describes a detection control apparatus for a moving part in an air conditioner according to an embodiment of an aspect of the present invention with reference to fig. 1 to 19. The detection control device of the moving part is used for detecting whether the moving part such as a door panel and the like is blocked or meets an obstacle, and the moving part can move under the driving of the driving part.

According to an embodiment of the present invention, as shown in fig. 1 and fig. 18 and 19, the driving part may be a driving motor, the moving part may be a door panel 300 of an air conditioner, and the door panel 300 may be a slidable door panel, wherein the door panel 300 of the air conditioner may be driven by the driving motor 100. Specifically, the cabinet of the air conditioner has a slidable door panel 300 thereon, when the air conditioner is started, the control unit 30 of the air conditioner can drive the door panel 300 to open by the driving motor 100, and when the air conditioner is closed, the control unit 30 of the air conditioner can drive the door panel 300 to close by the driving motor 100, thereby improving the aesthetic appearance of the product. When the number of the door panel 300 is one, the door panel 300 can be opened to one side; when the door panel 300 is two, the door panel 300 can be opened to both sides.

According to an embodiment of the present invention, the driving motor may be a stepping motor, the stepping motor is controlled in an open loop, and the control unit 30 may detect whether the stepping motor is locked or not, that is, whether the door panel 300 is stuck or not, through the structures of the magnetic assembly and the hall detection assembly, so as to prevent the stepping motor from being continuously in an interference state and from adversely affecting the operation of the stepping motor and the product.

As shown in fig. 1 to 13, the detection control device for a moving part in an air conditioner according to an embodiment of the present invention includes: a magnet unit 11, x hall sensing assemblies 20, and a control unit 30.

Wherein the magnetic unit 10 is fixed on a moving part of the air conditioner, such as a door panel 300, and the magnetic unit includes a z-layer magnetic assembly 10, for example, the z-layer magnetic assembly 10 may be fixed on a side of the moving part facing the inside of the air conditioner, wherein z is an integer greater than 1. A plurality of N magnetic poles and/or a plurality of S magnetic poles are spaced on the detection surface of each layer of magnetic assembly 10. According to an embodiment of the present invention, when a plurality of N magnetic poles and a plurality of S magnetic poles are distributed on the detection surface of the magnetic assembly 10, the N magnetic poles and the S magnetic poles are arranged at intervals one by one; when a plurality of N magnetic poles are distributed on the detection surface of the magnetic assembly 10, a first blank region is disposed between adjacent N magnetic poles; when a plurality of S magnetic poles are distributed on the detection surface of the magnetic assembly 10, a second blank region is provided between adjacent S magnetic poles at an interval. That is, as shown in fig. 2-3, when the magnetic assembly 10 has a plurality of N magnetic poles and a plurality of S magnetic poles distributed thereon, the plurality of N magnetic poles and the plurality of S magnetic poles are arranged at intervals one by one, that is, the arrangement rule on the magnetic assembly 10 is N magnetic poles-S magnetic poles-N magnetic poles-S magnetic poles, and at this time, the magnetic assembly 10 is a bipolar magnetic assembly; as shown in fig. 4-5, when the N magnetic poles are filled on each layer of magnetic assembly 10 at intervals, the N magnetic poles and the blank regions are distributed on each layer of magnetic assembly 10 at intervals, that is, the arrangement rule on the magnetic assembly 10 is N magnetic poles-first blank regions-N magnetic poles-first blank regions, and then the magnetic assembly 10 is a unipolar magnetic assembly; as shown in fig. 6-7, when the magnetic assembly 10 of each layer is filled with the S magnetic poles at intervals, the S magnetic poles and the blank regions are distributed at intervals on the magnetic assembly 10 of each layer, that is, the arrangement rule of the magnetic assembly 10 is S magnetic pole-second blank region-S magnetic pole-second blank region, at this time, the magnetic assembly 10 is a unipolar magnetic assembly, wherein the blank regions including the first blank region or the second blank region means that the region without any magnetism is a non-magnetic region.

The magnetism phase-match of magnetic pole on the detection face of x hall determine module 20 and the magnetic component 10 that corresponds, x hall determine module 20 fixes on the air conditioner body, and hall determine module 20 is close to the inspection face setting of the magnetic component 10 that corresponds, and the magnetic pole change of the corresponding magnetic component 10 of every hall determine module 20 response is in order to correspond the corresponding induction signal that generates when moving part removes, and x is for being greater than 1 integer, and x can be less than or equal to z. That is to say, the x hall sensing elements 20 are disposed correspondingly to the sensing surface of the x-layer magnetic element 10, that is, each hall sensing element 20 may be disposed correspondingly to the sensing surface of the corresponding magnetic element 10, and the x hall sensing elements 20 may be close to the x-layer magnetic element 10 but not in contact with the x-layer magnetic element 10, and may be within the magnetic field sensing range of the x-layer magnetic element 10.

The corresponding magnetic poles of the x-layer magnetic assembly 10 are sequentially staggered by a preset angle, and the connecting line of the x hall detection assemblies 20 is perpendicular to the moving direction of the magnetic assembly 10, so that the x induction signals are sequentially staggered by a preset phase angle. That is, the x-layer magnetic assembly 10 moves synchronously with the moving part as it moves. It should be understood that the same arrangement may be used for the x-layer magnetic elements, for example, the arrangement of the z-layer magnetic elements may be N-S-N-S. Alternatively, the magnetic elements of different layers may have different arrangement rules, for example, the arrangement rule of the first layer of magnetic elements may be S-pole-second clear area-S-pole-second clear area, and the arrangement rule of the second layer of magnetic elements may be N-pole-first clear area-N-pole-first clear area. Also, the number of pole pairs of the x-layer magnetic assemblies is the same, e.g., the first layer magnetic assembly includes m pairs of S poles-the second clear area, and the second layer magnetic assembly also includes m pairs of N poles-the first clear area. The magnetic poles of the remaining (z-x) layer magnetic assembly 10 are not limited.

For example, when the arrangement rule of the first layer of magnetic elements 10 may be S pole-second empty area-S pole-second empty area, and the arrangement rule of the second layer of magnetic elements 10 may be N pole-first empty area-N pole-first empty area, and the arrangement rule of the third layer of magnetic elements 10 may be N pole-S pole-N pole-S pole, the logarithm of the S pole-second empty area of the first layer of magnetic elements 10, the logarithm of the N pole-first empty area of the second layer of magnetic elements 10, and the logarithm of the N pole-S pole of the third layer of magnetic elements 10 are the same, e.g., m, the S pole, the second pole, and the second pole of the first layer of magnetic elements 10 are the same, and the predetermined angle is sequentially staggered between the magnetic poles capable of generating the same induction signal, The N pole of the second magnetic assembly 10 and the N pole of the third magnetic assembly 10 generate the same induction signal, and the second empty area of the first magnetic assembly 10, the first empty area of the second magnetic assembly 10 and the S pole of the third magnetic assembly 10 generate another induction signal, so that the N pole of the j-th pair of poles of the second magnetic assembly 10 is offset by a predetermined angle in the first direction with respect to the S pole of the j-th pair of poles of the first magnetic assembly 10, the N pole of the j-th pair of poles of the third magnetic assembly 10 is offset by a predetermined angle in the first direction with respect to the N pole of the j-th pair of poles of the second magnetic assembly 10, and likewise, the first empty area of the j-th pair of poles of the second magnetic assembly 10 is offset by a predetermined angle in the first direction with respect to the second empty area of the j-th pair of poles of the first magnetic assembly 10, the S-pole of the jth pair of magnetic poles of the third-layer magnetic assembly 10 is shifted by a predetermined angle in the first direction with respect to the first blank region of the jth pair of magnetic poles of the second-layer magnetic assembly, j being 1, 2, 3, … …, m. The same arrangement of the same layer magnetic assemblies 10 can be used in the same manner as described above, and will not be described in detail here.

It should be noted that, as shown in fig. 7-13, the x hall sensing elements 20 are arranged on the same vertical line, that is, the relative position between each hall sensing element 20 and each layer of magnetic element 10 is consistent, for example, when any hall sensing element 20 is located at the middle position of the corresponding layer of magnetic element 10, the other hall sensing elements 20 are also located at the middle position of the corresponding layer of magnetic element 10. Specifically, the detecting surface of each layer of magnetic assembly 10 may be filled with N magnetic poles and S magnetic poles at intervals, when the moving component moves, each layer of magnetic assembly 10 moves synchronously with the moving component, the N magnetic poles and S magnetic poles on each layer of magnetic assembly 10 may alternately pass through the corresponding hall detecting assemblies 20, and each hall detecting assembly 20 outputs a corresponding sensing signal according to the sensed magnetic pole change. Alternatively, the detecting surface of each layer of magnetic assembly 10 may be filled with N magnetic poles and first empty areas at intervals, when the moving component moves, each layer of magnetic assembly 10 moves synchronously with the moving component, the N magnetic poles and the first empty areas on each layer of magnetic assembly 10 may alternately pass through the corresponding hall detecting assemblies 20, and each hall detecting assembly 20 outputs a corresponding sensing signal according to the sensed magnetic pole change. Alternatively, the sensing surface of each layer of magnetic assembly 10 may be filled with the S-pole and the second empty area at intervals, when the moving component moves, each layer of magnetic assembly 10 moves synchronously with the moving component, the S-pole and the second empty area on each layer of magnetic assembly 10 may alternately pass through the corresponding hall sensing assembly 20, and each hall sensing assembly 20 outputs a corresponding sensing signal according to the sensed change of the magnetic pole.

The control unit 30 is connected with the x hall detection assemblies 20, and the control unit 30 judges whether the moving part is stuck according to the x induction signals.

Specifically, taking the example that a plurality of N magnetic poles and a plurality of S magnetic poles are distributed at intervals on the detection surface of each layer of magnetic assembly 10 as an example, during the moving process of the moving component, the x layer of magnetic assembly 10 moves along with the moving component, while the x hall detection assemblies 20 are fixed, the N magnetic poles and the blank area on the detection surface of each layer of magnetic assembly 10 sequentially pass through the corresponding hall detection assemblies 20, so that the x hall detection assemblies 20 sense the change of the magnetic poles of the magnetic assembly 10 to sequentially output x paths of sensing signals such as high and low level pulse sequences, when the moving component moves according to a preset speed, the x paths of sensing signals output by the x hall detection assemblies 20 will conform to a corresponding rule, and when the moving component stops, the magnetic poles sensed by the x hall detection assemblies 20 will remain unchanged, and the x paths of sensing signals will not conform to a corresponding rule, thereby, the control unit 30 determines the state of the moving part, for example, whether the moving part is stuck, according to the x sensing signals.

It should be understood that the case of spacing a plurality of S poles or a plurality of N poles on the detection surface of the magnetic assembly 10 is similar to the case of spacing a plurality of N poles and S poles, and will not be described herein again.

According to one embodiment of the present invention, the magnetic assembly 10 may be a strip magnetic tape, as shown in fig. 2-7, but is not limited thereto, for example, the magnetic assembly 10 may also be a sheet magnetic assembly or a strip magnetic assembly, etc.

According to one embodiment of the present invention, magnetic assembly 10 may be removably secured to a moving component, such as door panel 300, such as by adhesive bonding, snap-fit threading, or the like. That is, the strip tape may be fixed to the moving member so that the strip tape moves in synchronization with the moving member when the moving member moves.

Therefore, the magnetic assembly 10 is fixed on the door panel 300, and the x hall detection assemblies 20 can be fixed on the air conditioner body, so that the integral installation is convenient and fast, and the wiring problem is avoided.

Specifically, the x-layer magnetic assembly 10 may be mounted at any position of the moving part. Taking the door panel 300 as an example, the x-layer magnetic component 10 is preferably installed in the middle of the door panel 300, wherein when two door panels 300 are adopted, i.e. a dual-opening and closing mechanism is adopted, one-side installation or two-side installation can be selected, i.e. the magnetic component 10 can be installed on one of the door panels, or the magnetic components 10 can be installed on both of the door panels.

According to an embodiment of the present invention, the x hall sensing elements 20, such as hall elements, may be packaged in both a chip package and a package, and the x hall sensing elements 20 are fixed on a PCB (Printed Circuit Board) Board and fixed to the air conditioner body through the PCB Board, and are located on one side of the magnetic element 10, close to the magnetic element 10 but not in contact, within a magnetic field sensing range.

According to one embodiment of the present invention, as shown in fig. 8-13, the plurality of N-poles and/or the plurality of S-poles of each layer of magnetic assembly 10 are arranged along the moving direction of the moving part. That is, the magnetic assembly 10 may be fixed to the moving member in a direction perpendicular to the moving direction of the moving member. In other words, the magnetic assembly 10 is sequentially spaced apart by a plurality of N magnetic poles and/or a plurality of S magnetic poles along a moving direction of the moving member, for example, a door opening/closing direction of the door panel 300.

Thus, when each layer of magnetic assembly 10 is filled with N and S magnetic poles at intervals, the N and S magnetic poles on each layer of magnetic assembly 10 can alternately pass through the corresponding hall sensing assemblies 20 when the moving part moves, so that each hall sensing assembly 20 generates a corresponding sensing signal. When each layer of magnetic assembly 10 is filled with the N magnetic poles and the first empty areas at intervals, the N magnetic poles and the first empty areas on each layer of magnetic assembly 10 can alternately pass through the corresponding hall sensing assemblies 20 when the moving part moves, so that each hall sensing assembly 20 generates a corresponding sensing signal. When each layer of magnetic assembly 10 is filled with the S-pole and the second empty area at intervals, the S-pole and the second empty area on each layer of magnetic assembly 10 can alternately pass through the corresponding hall sensing assemblies 20 when the moving part moves, so that each hall sensing assembly 20 generates a corresponding sensing signal.

According to one embodiment of the present invention, as shown in fig. 2 to 13, the widths of the x-layer magnetic assemblies 10 in the moving direction of the moving part are all equal, and the x-layer magnetic assemblies 10 are aligned. That is, the x-layer magnetic assembly 10 takes on the same width, so that the x hall-effect sensing assemblies start sensing at the same time and end sensing at the same time. In other words, the x hall sensing elements can simultaneously enter the beginning of the x-layer magnetic element 10 and simultaneously exit the ending of the x-layer magnetic element 10.

Further, according to the embodiment of fig. 2-13, the x-layer magnetic assemblies 10 are sequentially disposed one above the other in a direction perpendicular to the moving direction of the moving part. That is, the x-layer magnetic assemblies 10 may be sequentially disposed from top to bottom on the moving part without overlapping, e.g., with the first layer magnetic assembly on top and the second layer magnetic assembly on bottom.

In addition, according to some embodiments of the present invention, as shown in fig. 2, 4, 6, 8, 10 and 12, the x-layer magnetic component may be combined from x separate magnetic components. Alternatively, as shown in fig. 3, 5, 7, 9, 11 and 13, the x-layer magnetic assemblies 10 may be integrally disposed, and the corresponding magnetic poles are sequentially staggered by a predetermined distance in the x-layer, and for example, the corresponding magnetic poles are staggered by a predetermined distance in the upper and lower layers.

Further, according to one embodiment of the present invention, as shown in fig. 2-13, the plurality of N-poles and/or the plurality of S-poles on each layer of magnetic assembly 10 are arranged in an equal width manner. That is, when a plurality of N poles and a plurality of S poles are distributed on the detection surface of the magnet assembly 10, the width of each N pole is the same and the width of each S pole is the same; or when a plurality of N magnetic poles are distributed on the detection surface of the magnetic assembly 10 at intervals, a first blank area is distributed between two adjacent N magnetic poles; or when a plurality of S magnetic poles are distributed on the detection surface of the magnetic assembly 10 at intervals, a second blank area is distributed between two adjacent S magnetic poles.

It should be noted that the width of the N magnetic pole and/or the S magnetic pole is as narrow as possible under the premise of ensuring the magnetic field strength, for example, 1 to 2mm can be achieved, and the magnetic field strength is required to be determined according to the hall sensing parameters of the hall sensing assembly 20.

Specifically, when the magnetic assembly 10 is filled with the N-pole and the first empty area or the S-pole and the second empty area at intervals, the magnetic area width of the N-pole or the S-pole can be obtained according to the following formula:

d1＝(1+(arcsin(X/A)+arcsin(Y/A))/π)*D/p/2，

where D1 is the width of the magnetic region of the N or S magnetic pole, a is the maximum magnetic flux density of the N or S magnetic pole, X is the operating point of the hall sensing element, Y is the release point of the hall sensing element, D is the length of the magnetic element 10 along the moving direction of the moving part, and p is the number of the N or S magnetic poles.

That is, the magnetic region width of the N magnetic pole may be set according to the number of N magnetic poles, or the magnetic region width of the S magnetic pole may be set according to the number of S magnetic poles.

Accordingly, the width of the first blank area or the second blank area may be obtained according to the following formula:

d2＝D/p–d1。

where D2 is the width of the first blank area or the second blank area, D1 is the width of the magnetic area of the N-pole or the S-pole, D is the width of the magnetic assembly 10 along the moving direction of the moving component, and p is the number of the N-pole or the S-pole.

That is, the width of the first blank region may be set according to the number of N poles and the magnetic region width of the N poles, or the width of the second blank region may be set according to the number of S poles and the magnetic region width of the S poles.

In addition, according to a specific example of the present invention, the width of the magnetic region, i.e., the N-pole magnetic region, and the width of the first blank region may be approximately equal, or the width of the magnetic region, i.e., the S-pole magnetic region, and the width of the second blank region may be approximately equal. That is, the width of the N-pole and the width of the first blank region may be equal, and the width of the S-pole and the width of the second blank region may also be equal, thereby simplifying the design and manufacturing difficulty of the magnetic assembly.

According to one embodiment of the present invention, the x hall sensing assemblies 20 may match the magnetic arrangement of the poles on the magnetic assembly 10. For example, when the magnetic assembly 10 is filled with N and S magnetic poles at intervals, the x hall sensing assemblies 20 may be bipolar hall elements, which may sense the N and S magnetic poles respectively to generate different signals when sensing different magnetic poles; for another example, when the magnetic assembly 10 is filled with the N-pole and the first blank area or filled with the S-pole and the second blank area at intervals, the x hall sensing assemblies 20 may be unipolar hall elements, and the unipolar hall elements may sense the matched magnetic poles to generate sensing signals when sensing the matched magnetic poles, that is, the selection type of the unipolar hall elements is matched with the unipolar magnetic assembly, if the unipolar magnetic assembly is the N-pole type, the unipolar hall is also selected as the N-pole type, and if the unipolar magnetic assembly is the S-pole type, the unipolar hall is also selected as the S-pole type.

According to one embodiment of the present invention, each hall sensing assembly 20 may generate a corresponding sensing signal according to the sensed magnetic pole type.

For example, when the plurality of N poles and the plurality of S poles are distributed on the magnetic member 10, the hall sensing member 20 corresponding to the magnetic member generates a first level when facing the N poles, and generates a second level when facing the S poles. It should be noted that the first level may be a high level and the second level may be a low level, or the first level may be a low level and the second level may be a high level, and the level state may be specifically determined according to the type of the hall sensing assembly 20.

In this way, when the N-pole and the S-pole on the magnetic assembly 10 alternately pass through the corresponding hall sensing assemblies 20, the corresponding hall sensing assemblies 20 will output stable high-low level pulse sequences, and thus, the periods of the x-path high-low level pulse sequences that can be output by the x hall sensing assemblies 20 are fixed and the same, and the duty ratio is 50%.

For another example, when a plurality of N magnetic poles are distributed on the magnetic member 10, the hall sensing member 20 corresponding to the magnetic member generates a first level when facing the N magnetic poles, and generates a second level when facing the first blank region. In this way, when the N magnetic poles and the first blank regions on the magnetic assembly 10 alternately pass through the corresponding hall sensing assemblies 20, the corresponding hall sensing assemblies 20 will output stable high-low level pulse sequences, and thus, the periods of the x high-low level pulse sequences output by the x hall sensing assemblies 20 are fixed and the same, and the duty ratio is 50%.

For another example, when a plurality of S poles are distributed on the magnetic member 10, the hall sensing member 20 corresponding to the magnetic member generates a first level when facing the S poles, and generates a second level when facing the second blank area. In this way, when the S magnetic pole and the second blank area on each layer of magnetic assembly 10 alternately pass through the corresponding hall sensing assemblies 20, the corresponding hall sensing assemblies 20 will output stable high-low level pulse sequences, and thus, the periods of the x high-low level pulse sequences output by the x hall sensing assemblies 20 are fixed and the same, and the duty ratio is 50%.

Therefore, the N magnetic poles and/or the S magnetic poles on the magnetic component 10 can be very dense (the width of the magnetic poles can be 1-2mm), the sensitivity is high, and the frequency of feedback pulses can be improved, so that the detection time is shortened, and the detection sensitivity is improved. And based on the Hall effect, the method is stable and reliable, has low interference, stable pulse waveform and rapid high and low level jump.

According to an embodiment of the present invention, the preset angles include a first preset angle, a second preset angle, and a third preset angle, and when the plurality of N magnetic poles and the plurality of S magnetic poles are distributed on the detection surface of each layer of magnetic assemblies 10, the x layers of magnetic assemblies 10 are staggered by the third preset angle according to the sum of the numbers of the N magnetic poles and the S magnetic poles; when a plurality of N magnetic poles are distributed on the detection surface of each layer of magnetic assembly 10, the x layers of magnetic assemblies 10 are staggered by a first preset angle according to the sum of the number of the N magnetic poles and the first blank area; when a plurality of S magnetic poles are distributed at intervals on the detection surface of each layer of magnetic assembly 10, the x layers of magnetic assemblies 10 are staggered by a second preset angle according to the sum of the number of the S magnetic poles and the second blank area.

That is to say, the x-layer magnetic assemblies 10 may be distributed in a staggered manner, and the x-layer magnetic assemblies 10 may be staggered by a preset distance in accordance with the width of the magnetic poles of the magnetic assemblies 10, so that the x-path sensing signals respectively output by the x hall detection assemblies 20 are sequentially staggered by a preset phase angle, thereby improving the detection sensitivity in multiples.

As shown in fig. 2 to 13, taking two layers of magnetic assemblies 10 as an example, the upper layer magnetic assembly 10A and the lower layer magnetic assembly 10B are both arranged in the same manner, and the magnetic poles of the same magnetism of the upper layer magnetic assembly 10A and the lower layer magnetic assembly 10B are staggered by a preset distance, that is, as shown in fig. 2 to 3 and fig. 8 to 9, each N magnetic pole of the lower layer magnetic assembly 10B is staggered by a preset distance with respect to the corresponding N magnetic pole of the upper layer magnetic assembly 10A, and each S magnetic pole of the lower layer magnetic assembly 10B is staggered by a preset distance with respect to the corresponding S magnetic pole of the upper layer magnetic assembly 10A. As shown in fig. 4-5 and 10-11, each N pole of the lower magnetic assembly 10B is offset by a predetermined distance with respect to the corresponding N pole of the upper magnetic assembly 10A, and each empty area of the lower magnetic assembly 10B is offset by a predetermined distance with respect to the corresponding empty area of the upper magnetic assembly 10A. As shown in fig. 6-7 and 12-13, each S pole of lower magnetic assembly 10B is offset by a predetermined distance relative to the corresponding S pole of upper magnetic assembly 10A, and each empty area of lower magnetic assembly 10B is offset by a predetermined distance relative to the corresponding empty area of upper magnetic assembly 10A.

Taking the x-layer magnetic assembly 10 moving in the opening direction shown by the arrow in fig. 3 as an example, the sensing signal output by the hall sensing assembly 20B corresponding to the lower-layer magnetic assembly 10B lags behind the preset phase angle of the hall sensing assembly 20A corresponding to the upper-layer magnetic assembly 10B.

Specifically, the first preset distance or the second preset angle, or the third preset angle may be determined according to the following formula:

d＝s/x

where d is a first preset distance, a second preset angle, or a third preset angle, S is a magnetic pole width of each N magnetic pole or S magnetic pole, and x is the number of layers of the magnetic assembly 10.

It should be noted that, when a plurality of N magnetic poles and a plurality of S magnetic poles are distributed at intervals on each layer of magnetic assembly 10, the magnetic pole widths of the N magnetic poles and the S magnetic poles are equal, and the magnetic pole width of each N magnetic pole or S magnetic pole may be equal to the ratio of the width D of the magnetic assembly 10 in the moving direction of the moving component to the total number p of the N magnetic poles and the S magnetic poles, that is, S is D/p; when a plurality of N magnetic poles are distributed on each layer of magnetic assembly 10 at intervals, the magnetic pole width of each N magnetic pole may be approximately equal to the ratio of the width D of the magnetic assembly 10 in the moving direction of the moving part to the total number p of the N magnetic poles and the first blank area, that is, s is D/p; when a plurality of S magnetic poles are spaced apart from each layer of the magnetic assembly 10, the magnetic pole width of each S magnetic pole may be approximately equal to the ratio of the width D of the magnetic assembly 10 in the moving direction of the moving component to the total number p of the S magnetic poles and the blank area, i.e., S ═ D/p.

That is, the preset distance may also be determined according to the following formula, i.e., D ═ D/p/x.

Specifically, for example, the number x of layers of the magnetic assemblies 10 is 2, the corresponding magnetic poles of the upper and lower magnetic assemblies are staggered by S/2, assuming that a plurality of N magnetic poles and a plurality of S magnetic poles are distributed at intervals on each layer of the magnetic assemblies 10, the width D of each magnetic assembly 10 is 15mm, and the total number p of the N magnetic poles and the S magnetic poles is 15, then the preset distance D is D/p/x 15/15/2 mm 0.5mm, that is, the corresponding magnetic poles of the upper and lower magnetic assemblies are staggered by 0.5 mm. More specifically, as shown in fig. 8 to 13, the lower magnetic assembly 10B is shifted by s/2, for example, 0.5mm with respect to the upper magnetic assembly 10A, and when the hall sensing assembly 20A corresponding to the upper magnetic assembly 10A is located at the start position of the N pole, the hall sensing assembly 20B corresponding to the lower magnetic assembly 10B is located at the position 1/2 of the N pole, and accordingly, when the x-layer magnetic assembly 10 moves in the on direction indicated by the arrow in fig. 3, the sensing signal output by the hall sensing assembly 20B corresponding to the lower magnetic assembly 10B lags by 90 ° with respect to the hall sensing assembly 20A corresponding to the upper magnetic assembly 10B.

According to an embodiment of the present invention, the hall sensing element 20 generates a first level when facing the N pole and a second level when facing the S pole, or the hall sensing element 20 generates a first level when facing the N pole and a second level when facing the first clear area, or the hall sensing element 20 generates a first level when facing the S pole and a second level when facing the second clear area, and the x-way sensing signal can configure y level state combinations, y > x. According to an embodiment of the present invention, the number y of the level state combinations is x times the number of the level states of each sensing signal, that is, y is 2 x.

As shown in fig. 14, the control unit 30 includes: a timer 301 and a control chip 302.

Wherein the timer 301 is configured to start timing when any one of the y level state combinations occurs, so as to time the duration of each of the y level state combinations; the control chip 302 is connected with the timer 301, the control chip 302 is further connected with the x hall detection assemblies 20, and the control chip 302 judges that the moving part is blocked when the duration of any level state combination is greater than a preset time threshold.

That is, the widths of the N-pole or S-pole of the x-layer magnetic assembly 10 matching the magnetic assembly 10 are staggered by a predetermined distance, so that the x-paths of sensing signals respectively output by the x hall sensing assemblies 20 are sequentially staggered by a predetermined phase angle, and thus different level state combinations can be formed at the same time. The control chip 302 can determine whether the moving component is jammed by detecting whether the duration time of each level state combination exceeds a preset time threshold. Therefore, the detection time can be further shortened in multiples by adopting the multilayer magnetic assemblies in staggered distribution and matching with the Hall detection assemblies with the same number, and the effect of reducing the detection time in multiples can be achieved.

Specifically, taking the example that the magnetic assemblies 10 are filled with N magnetic poles and S magnetic poles at intervals as an example, when the moving component moves, the x layers of magnetic assemblies 10 move synchronously with the moving component, the x hall detection assemblies 20 are fixed, and the N magnetic poles and S magnetic poles on each layer of magnetic assemblies 10 alternately pass through the corresponding hall detection assemblies 20, so that the x hall detection assemblies 20 respectively generate high and low level pulse sequences with a duty ratio of 50%.

The corresponding magnetic poles on the x-layer magnetic assembly 10 are sequentially staggered by a preset distance according to the formula D ═ D/p/x, and accordingly, waveforms with a phase angle of 180 °/x can be obtained by two adjacent hall detection assemblies 20. Thus, each waveform can be divided equally into 2x level state combinations, and the duration tn of each level state combination is 1/x of the duration of the high level state or the low level state of any signal, that is, tn is S/v/x, where r is the moving speed of the x-layer magnetic assembly 10, that is, the moving speed of the moving part, S is half the width of the N-pole and the S-pole on the magnetic assembly 10, and x is the number of layers of the magnetic assembly 10. Therefore, the detection time can be further shortened by times by adopting the staggered distribution of the plurality of layers of magnetic assemblies, for example, the detection time can be reduced by times by using more or less layers of magnetic assemblies.

It should be understood that when a plurality of N magnetic poles are spaced on the detection surface of the magnetic assembly 10, s is half the width of the N magnetic poles and the first blank region on the magnetic assembly 10; when a plurality of S magnetic poles are distributed on the detection surface of the magnetic assembly 10 at intervals, S is half of the width of the S magnetic pole and the second blank area on the magnetic assembly 10.

As shown in fig. 15, taking x as 2 as an example, two hall sensing elements 20 can output two waveforms each delayed by 90 ° in phase angle, that is, the output waveform of the hall sensing element 20B is delayed by 90 ° with respect to the output waveform of the hall sensing element 20A. Thus, one period of each waveform can be equally divided into four level state combinations, namely 10, 11, 01 and 00, wherein 1 represents high level and 0 represents low level, and the duration tn of each level state combination is 1/2 which is the duration of the high level or low level state of any signal, and is s/v/2, so that the detection sensitivity is improved by two times.

When the moving part is stuck, the corresponding magnetic pole of each hall sensing assembly 20 does not change any more, so the output level of each hall sensing assembly 20 will be continuously high or continuously low. As shown in fig. 16, the moving component is stuck at time t1 and recovers at time t2, tn is the duration of each level state combination when no sticking occurs, td is a preset time threshold, when sticking occurs, the two waveforms maintain the current level state, and when the duration is greater than td, the moving component is judged to be stuck. The preset time threshold td is k × tn, and the value range of k is 1-4, preferably 1.5.

As described above, the detection process for detecting whether the moving part is stuck according to the embodiment of the present invention is as follows:

when the moving part moves, the control chip 302 starts a detection function and controls the timer 301 to start timing, the control chip 302 can collect the sensing signals output by the x hall detection assemblies 20, when any one path of sensing signal jumps in high and low levels, the control timer 301 is cleared, the control chip 302 can judge whether the timing value of the timer 301 is greater than a preset time threshold td, if the timing value of the timer 301 is greater than the preset time threshold td, the moving part is judged to be stuck, and the control chip 302 outputs a stuck protection signal to execute a protection action, for example, the moving part is controlled to stop moving or move reversely; if the timing value of the timer 301 is less than or equal to the preset time threshold value td, it is determined that the moving component is not jammed, and the control chip 302 may control the moving component to continue to rotate forward.

It should be understood that the embodiment in which each layer of magnetic assembly 10 is filled with N poles and first empty regions at intervals and each layer of magnetic assembly 10 is filled with S poles and second empty regions at intervals is substantially the same as the aforementioned embodiment in which each layer of magnetic assembly 10 is filled with N poles and S poles at intervals, except that when each layer of magnetic assembly 10 is filled with N poles and first empty regions at intervals, the N poles and first empty regions alternately pass through the corresponding hall sensing assemblies 20, and when each layer of magnetic assembly 10 is filled with S poles and second empty regions at intervals, the S poles and second empty regions alternately pass through the corresponding hall sensing assemblies 20, and will not be described in detail herein.

From this, whether can effectively detect the moving part meet the barrier to shorten check-out time, can obtain the retardant information of door plant fast, accomplish slight touching can detect retardant effect, thereby in time take corresponding tactics to adjust the motion of door plant, avoid causing the damage to the mechanism, improved user and used the experience satisfaction simultaneously.

In addition, according to an embodiment of the present invention, as shown in fig. 17, the power terminals of the x hall sensing elements 20 are all connected to a preset power VCC, for example, +5V, through a first resistor R1, the ground terminals of the x hall sensing elements 20 are grounded, and a first capacitor C1 is connected between the power terminals and the ground terminals of the x hall sensing elements 20 in parallel, wherein the sensing terminal of each hall sensing element 20 senses the magnetic pole change of the corresponding magnetic element 10, and the output terminal of each hall sensing element 20 outputs a corresponding sensing signal.

Further, as shown in fig. 17, the detection control device for the moving part in the air conditioner further includes x output circuits 40, the x output circuits 40 are connected to the output ends of the x hall sensing assemblies 20 in a one-to-one correspondence, and each output circuit 40 includes: the second resistor R2 and the third resistor R3, the second resistor R2 and the third resistor R3 are connected in series, one end of the second resistor R2 and one end of the third resistor R3 which are connected in series are connected with a preset power VCC, the other end of the second resistor R2 and the other end of the third resistor R3 which are connected in series are connected with the control unit 30, namely the control chip 302, a node is arranged between the second resistor R2 and the third resistor R3 which are connected in series, and the node is connected with the output end of the corresponding Hall detection assembly 20.

The second resistor R2 is a pull-up resistor, and the third resistor R3 is a current-limiting resistor.

That is, each hall sensing element 20 can supply 5V power, so that each hall sensing element 20 can output a high-low level pulse sequence with an amplitude of 5V, each high-low level pulse sequence is provided to the control unit 30 through a corresponding output circuit, the control unit 30 can time the duration of the level state combination of the x high-low level pulse sequences, and determine whether the moving component is jammed by comparing the time with the preset time threshold.

Further, according to an embodiment of the present invention, as shown in fig. 18 and 19, the driving motor 100 may drive the door panel 300. The detection control apparatus of the moving part in the air conditioner according to the embodiment of the present invention may determine whether the door panel 300 is stuck, for example, whether it meets an obstacle. Specifically, for example, when each layer of magnetic assembly 10 is filled with N magnetic poles and S magnetic poles at intervals, when the x layer of magnetic assembly 10 moves synchronously with the door panel 300, the N magnetic poles and S magnetic poles on each layer of magnetic assembly 10 alternately pass through the corresponding hall detection assemblies, so that the x hall detection assemblies respectively output stable high and low level pulse sequences, and the duty ratio is 50%.

When the door panel 300 is stuck, for example, a foreign object is stuck on the door panel 300 or a finger is accidentally extended in the door panel, the door panel 300 stops moving, the magnetic pole corresponding to each hall detection assembly does not change any more, and the output level of each hall detection assembly is continuously at a high level or continuously at a low level. The control unit 30 may determine whether the door panel 300 is stuck, for example, meets an obstacle, by detecting whether the duration of each level state combination exceeds a preset time threshold.

From this, whether can effectively detect door plant 300 and meet the barrier to shorten check-out time, can obtain the jamming information of door plant fast, do slight touching can detect the effect of jamming, thereby in time take corresponding tactics to adjust the motion of door plant, avoid causing the damage to the mechanism, improved user and used the experience satisfaction simultaneously. And can shorten check-out time through multilayer magnetic component and many hall determine module cooperations, promote detectivity, prevent to cause the injury for the user for example clip finger etc. promote user's experience.
