BACKGROUND
Technical Field
[0001] The present invention relates to the field of air conditioning technologies, and
in particular, to a vertical air-conditioner and a vertical air-conditioner air supply
apparatus.
Related Art
[0002] When a conventional vertical air-conditioner supplies air, air is subjected to heat
exchange by a heat exchanger and is directly blown out from an air outlet provided
on the air-conditioner under the action of an internal fan, and all of the blown-out
air is heat-exchanged air. Generally, no additional air supply apparatus is disposed
between the heat exchanger and the air outlet. One disadvantage of such an air supply
method of the air-conditioner is that indoor air circulation is slow because the supplied
air is all heat-exchanged air and the air flow rate is low; another disadvantage is
that the supplied air is not mild enough, and especially in the cooling mode, the
blown-out cool air directly blows on a user, making the user feel uncomfortable.
[0003] To solve the foregoing problems, the applicant proposed an air-conditioner air supply
apparatus that can be applied to an air-conditioner. The air-conditioner air supply
apparatus includes a circular cover body. A through-duct running through the circular
cover body is formed in the middle of the circular cover body. A circular opening
is formed on a wall of the circular cover body. A plurality of circular deflectors
is disposed on the circular opening. A circular air outlet duct is formed between
adjacent circular deflectors. After the air-conditioner air supply apparatus is disposed
between an air-conditioner heat exchanger and an air outlet of an air-conditioner
housing, the air intake volume of the air-conditioner can be increased, indoor air
circulation can be accelerated, and the air-conditioner is enabled to supply milder
air, thereby making the user feel more comfortable and improving the user experience.
However, because the circular deflector and the circular air outlet duct are both
formed on one circular cover body, it is not convenient to flexibly select and control
the structure of the circular deflector and air outlet duct, resulting in a narrow
application scope. Moreover, because the fan of the air-conditioner supplies air from
bottom to top, the heat-exchanged air is not uniformly distributed in the circumferential
direction when entering the circular air outlet duct, and the air flow rate is high
at the lower end of the circular air outlet duct but low at the left and right sides
of the circular air outlet duct. As a result, the air supplied by the air-conditioner
air supply apparatus is not uniformly distributed in the entire circumferential direction,
affecting the comfort of the user. How to design an air-conditioner air supply apparatus
and an air-conditioner that supply air uniformly, have a wide application range, and
can be conveniently assembled is the main problem that the present invention needs
to research.

air circulation, and further improves the overall uniformity of indoor air. Moreover,
the mixed air is mild, which makes the user feel more comfortable, thereby improving

DETAILED DESCRIPTION
[0025] The technical solutions of the present invention are further described in detail
below with reference to the accompanying drawings and the detailed description.
[0026] First, technical terms involved in the detailed description are briefly described.
The front end or rear end of each structural component as mentioned below is defined

to the user; front or rear, when used to describe the positions at which multiple
structural components are arranged, is also defined in terms of the position of an

from the inside of an air-conditioner and has been subjected to heat exchange by a
heat exchanger; non-heat-exchanged air refers to air from the environmental space
in which the air-conditioner is located, is relative to the heat-exchanged air, and
is part of air that is not directly from the heat exchanger; and mixed air refers
to air formed by mixing the heat-exchanged air with the non-heat-exchanged air.
[0027] Refer to an embodiment of a vertical air-conditioner of the present invention shown
in FIG. 1 and FIG. 2. FIG. 1 is a three-dimensional view of this embodiment, and FIG.
2 is a schematic view of a partial blast structure of FIG. 1.
[0028] As shown in FIG. 1 and FIG. 2, the air-conditioner of this embodiment includes a
front panel 2, a rear panel 3, a left panel, a right panel, a top plate and a bottom
plate (not marked in the figure) that constitute a housing of the air-conditioner.
The housing defines an internal air duct 4 of the air-conditioner. A circular mixed
air outlet 21 is formed on an upper part of the front panel 2, and a circular non-heat-exchanged
air inlet 31 is formed on an upper part of the rear panel 3 and at a position corresponding
to the mixed air outlet 21 on the front panel 2. A blower (not shown in the figure),
a heat exchanger 5 and an air-conditioner air supply apparatus 1 are disposed from
bottom to top in the internal air duct 4, and the blower 6 is arranged in such a manner
that air from the internal air duct 4 of the air-conditioner is blown out from the
mixed air outlet 21 on the front panel 2.
[0029] For the structure of the air-conditioner air supply apparatus 1, refer to FIG. 3
to FIG. 7.
[0030] As show in the schematic three-dimensional structural view in FIG. 3 and the schematic
view of a blast structure in FIG. 4, and with reference to FIG. 1 and FIG. 2, the
air-conditioner air supply apparatus 1 in this embodiment includes three circular
air guiding bodies, namely, a front-end circular air guiding body 11, a first middle
circular air guiding body 13, and a rear-end circular air guiding body 12. Each circular
air guiding body in the three circular air guiding bodies that are arranged sequentially
from front to rear is a single component, and is formed independently. The front-end
circular air guiding body 11 is hollow and has front and rear two openings, the front
opening is an air outlet 111, and the rear opening is an air inlet 112; the first
middle circular air guiding body 13 is hollow and has front and rear two openings,
the front opening is an air outlet 131, and the rear opening is an air inlet 132;
and the rear-end circular air guiding body 12 is hollow and has front and rear two
openings, the front opening is an air outlet 121, the rear opening is an air inlet
122, and the air inlet 122 is the non-heat-exchanged air inlet of the air-conditioner
air supply apparatus 1. After the front-end circular air guiding body 11, the first
middle circular air guiding body 13 and the rear-end circular air guiding body 12
are arranged sequentially from front to rear, a through-duct (not marked in the figure)
that runs through all the three circular air guiding bodies from front to rear is
formed in the middle. Moreover, a first circular heat-exchanged air duct 14 is formed
between the front-end circular air guiding body 11 and the first middle circular air
guiding body 13; a second circular heat-exchanged air duct 15 is formed between the
first middle circular air guiding body 13 and the rear-end circular air guiding body
12. When the air-conditioner air supply apparatus 1 is applied in the air-conditioner,
the internal air duct 4 of the air-conditioner is connected to the through-duct in
the air-conditioner air supply apparatus 1 by using the first circular heat-exchanged
air duct 14 and the second circular heat-exchanged air duct 15.
[0031] In addition, an airflow distribution assembly 16 that extends into the first circular
heat-exchanged air duct 14 and the second circular heat-exchanged air duct 15 is disposed
on the first middle circular air guiding body 13. Besides, for convenience of manufacturing,
the airflow distribution assembly 16 is preferably integrally formed with the first
middle circular air guiding body 13. Definitely, they may also be separately formed,
and then the airflow distribution assembly 16 is fixedly installed on the first middle
circular air guiding body 13.
[0032] With reference to FIG. 2, when the air-conditioner air supply apparatus 1 is assembled
into the air-conditioner, the rear-end circular air guiding body 12 is fixed to the
rear panel 3 of the air-conditioner, the first middle circular air guiding body 13
is first fixed to the front-end circular air guiding body 11 by using a screw, and
then the front-end circular air guiding body 11 that is fixed with the first middle
circular air guiding body 13 is fixed to the front panel 2 of the air-conditioner.
After it is fixed in place, the air outlet 111 of the front-end circular air guiding
body 11 used as an air outlet of the entire air-conditioner air supply apparatus 1
is assembled in an enclosed manner with the mixed air outlet 21 on the front panel
2; and the air inlet 122 in the rear-end circular air guiding body 12 used as a non-heat-exchanged
air inlet of the entire air-conditioner air supply apparatus 1 is assembled in an
enclosed manner with the non-heat-exchanged air inlet 31 on the rear panel 3.
[0033] In the air-conditioner that uses the air-conditioner air supply apparatus 1 of the
above structure, when the air-conditioner operates, indoor air enters the inside of
the air-conditioner, is accelerated by the blower, and enters the heat exchanger 5
for heat exchange. Heat-exchanged air after heat exchange is blown from the internal
air duct 4 to the air-conditioner air supply apparatus 1. The heat-exchanged air is
distributed by the airflow distribution assembly 16 to enter the first circular heat-exchanged
air duct 14 and the second circular heat-exchanged air duct 15 uniformly in the circumferential
direction, then enter the through-duct through the heat-exchanged air duct, and is
blown out from the air outlet 111 on the front-end circular air guiding body 11 and
the mixed air outlet 21 on the front panel 2 through the through-duct. Because the
heat-exchanged air is blown from the internal air duct 4 having a larger area into
the annular heat-exchanged air duct having a smaller area, the flow rate of the heat-exchanged
air blown out from the annular heat-exchanged air duct is increased, so that the surface
pressure of the corresponding annular air guiding body reduces to form a negative
pressure in the through-duct. Indoor air outside the air-conditioner is used as the
non-heat-exchanged air. Under the negative pressure, the non-heat-exchanged air enters
the through-duct from the non-heat-exchanged air inlet 31 on the rear panel 3 and
the air inlet 122 on the rear-end circular air guiding body 12, and is mixed with
the heat-exchanged air blown out from the circular heat-exchanged air duct to form
mixed air, and then sent to the indoors smoothly under guiding of an extended mixed
air flow guiding portion 113.
[0034] Under a certain fan rotating speed, air flow test and temperature detection is performed
on the vertical air-conditioner. After the foregoing air-conditioner air supply apparatus
1 is used, air flow of the inducted non-heat-exchanged air is about 1.1 times of air
flow of the heat-exchanged air, and air flow of the obtained mixed air is about 2.1
times of the air flow of the heat-exchanged air. Under a same condition, and compared
with air supply of an air-conditioner that does not use the air-conditioner air supply
apparatus 1, air flow of the air-conditioner increases about 1.1 times. Moreover,
if the room temperature is about 26, air blown out from the air-conditioner that does
not use the air-conditioner air supply apparatus 1 is the heat-exchanged air, and
a temperature of the heat-exchanged air is about 13 ; while after the air-conditioner
air supply apparatus 1 is used, the mixed air sent out by the air-conditioner is about
19.5 , and the temperature of the mixed air satisfies comfort requirements of the
human body sensible temperature better. Such mixed air is mild, which makes the user
feel more comfortable, thereby improving the comfort of the user. Moreover, part of
external air that is not subjected to heat exchange is sucked under the negative pressure
generated by the air supply apparatus 1, and becomes part of the air finally supplied
from the air-conditioner, which increases the overall air intake volume of the air-conditioner,
accelerates indoor air circulation, and further improves the overall uniformity of
indoor air.
[0035] In this embodiment, a plurality of circular air guiding bodies in a form of a single
component is combined to form the air-conditioner air supply apparatus 1, so that
it is convenient to control flexibly the structure of each circular air guiding body
according to requirements of air supply, and to manufacture conveniently circular
air guiding bodies of different structures, so as to ensure the uniformity of air
supply and the speed of the air supply. Moreover, because each circular air guiding
body is a single component, an assembling method of the entire air-conditioner air
supply apparatus 1 in the air-conditioner may be selected flexibly, thereby improving
the application scope of the air-conditioner air supply apparatus 1 and the production
efficiency of the air-conditioner. Moreover, an airflow distribution assembly is disposed
in a heat-exchanged air duct, so that the airflow distribution assembly can be used
to distribute heat-exchanged air that enters an air supply apparatus in a circumferential
direction, thereby improving the uniformity of air supply from the air supply apparatus.
[0036] With reference to the schematic structural radial section view in FIG. 5, in this
embodiment, in order to improve the air guiding performance of the air-conditioner
air supply apparatus 1, particularly the air guiding performance for the heat-exchanged
air, so as to send the mixed air out uniformly along a surface of an annular air guiding
body, surfaces of the three circular air guiding bodies are all curved surfaces, each
of the circular air guiding bodies gradually reduces from the air inlet of the circular
air guiding body to the air outlet of the circular air guiding body to from a structure
that a rear section is thicker than a front section, and an inner perimeter of the
air inlet of each of the circular air guiding bodies is greater than an inner perimeter
of the air outlet of the circular air guiding body. That is, using the first middle
circular air guiding body 13 as example, the inner perimeter of the air inlet 132
of the first middle circular air guiding body 13 is greater than the inner perimeter
of the air outlet 131 of the first middle circular air guiding body 13.
[0037] Moreover, the three circular air guiding bodies are arranged coaxially, the inner
perimeter of the air outlet of each of the circular air guiding bodies gradually increases
in a direction from the air inlet 122 of the rear-end circular air guiding body 12
to the air outlet 111 of the front-end circular air guiding body 11. That is, from
front to rear, the inner perimeter of the air outlet 111 of the front-end circular
air guiding body 11 is greater than the inner perimeter of the air outlet 131 of the
first middle circular air guiding body 13, and the inner perimeter of the air outlet
131 of the first middle circular air guiding body 13 is greater than the inner perimeter
of the air outlet 121 of the rear-end circular air guiding body 12. The inner perimeter
mentioned herein refers to the inner perimeter of a circular opening.
[0038] To increase smoothness of air flow, particularly smoothness of mixed air flow, the
air-conditioner air supply apparatus 1 may further dispose the mixed air flow guiding
portion 113 at a front end of the front-end circular air guiding body 11, that is,
the mixed air flow guiding portion 113 is located between the front-end circular air
guiding body 11 and the front panel 2 of the air-conditioner. Preferably, the front-end
circular air guiding body 11 is integrally formed with the mixed air flow guiding
portion 113, to form seamlessly combination, so as to ensure continuity of surfaces,
which facilitates air flow.
[0039] The front-end circular air guiding body 11 is a main component for guiding flow of
the heat-exchanged air, and a surface of the front-end circular air guiding body 11
is a curved surface, so as to guide the heat-exchanged air to enter the through-duct
along the front-end circular air guiding body 11. The mixed air flow guiding portion
113 is a main component for guiding flow of the mixed air that is formed by mixing
the heat-exchanged air and non-heat-exchanged air, and a surface of the mixed air
flow guiding portion 113 is of a structure of a flat surface or a slightly curved
surface (a curved surface with a relatively large radius of curvature), and is preferably
a flat surface. Besides, the mixed air flow guiding portion 113 gradually expands
outside overall from rear to front, to form a shape of a bellmouth, and can smoothly
guide flow of the mixed air from the through-duct to a front opening 1131 thereof,
so as to be blown out from the mixed air outlet 21 on the front panel 2 of the air-conditioner.
[0040] In addition, to facilitate assembling the air-conditioner air supply apparatus 1
on the air-conditioner, a rear end of the rear-end circular air guiding body 12 is
further provided with an installation portion 124. The installation portion 124 is
of a flanging structure, and is preferably integrally formed with the rear-end circular
air guiding body 12. The rear-end circular air guiding body 12 is a main component
for guiding flow of the heat-exchanged air and the non-heat-exchanged air, and a surface
of the rear-end circular air guiding body 12 uses a structure of curved surface, so
as to guide the heat-exchanged air and the non-heat-exchanged air to enter the through-duct
separately along inner and outer two air guiding surfaces. The installation portion
124 preferably uses a flanging structure with the surface being a flat surface, to
facilitate being installed fixedly with the rear panel 3 of the air-conditioner.
[0041] For the air-conditioner air supply apparatus 1 that can send out the mixed air that
is formed by the heat-exchanged air of the air-conditioner heat exchanger and the
external non-heat-exchanged air, the structure of the heat-exchanged air duct is of
great importance for reducing air resistance, reducing pressure loss and noise, and
therefore further affects the amount of the external non-heat-exchanged air sucked
in by the air-conditioner air supply apparatus and the temperature of the supplied
mixed air, and the structure of the heat-exchanged air duct mainly depends on a relative
position relationship of two adjacent circular air guiding bodies that form the air
duct and the structure of the air guiding bodies. Therefore, the heat-exchanged air
ducts of the air-conditioner air supply apparatus 1 in this embodiment specifically
use the structure shown in FIG. 6.
[0042] FIG. 6 is a simplified schematic structural view of FIG. 5, and the airflow distribution
assembly 16 is omitted in the figure. Any one of the heat-exchanged air ducts is arranged
according to the following conditions: using a first circular heat-exchanged air duct
14 formed between the front-end circular air guiding body 11 and the first middle
circular air guiding body 13 as an example, the air duct has an air outlet end 142
that is proximal to the through-duct of the air-conditioner air supply apparatus 1
and an air inlet end 141 that is distal from the through-duct and located at an opposite
side of the air outlet end 142, and the first circular heat-exchanged air duct 14
gradually reduces from the air inlet end 141 to the air outlet end 142.
[0043] Specifically, a front-end circular air guiding body n and the first middle circular
air guiding body 13 are arranged in such a manner that a diameter of a tangent circle
located in the first circular heat-exchanged air duct14 and between surfaces of the
two air guiding bodies gradually reduces by a reduction ratio of 5-25% from the air
inlet end 141 to the air outlet end 142, and preferably gradually reduces at a non-proportional
reduction speed. The reduction ratio is more preferably 10-20%. For example, as shown
in FIG. 6, there are three tangent circles in the first circular heat-exchanged air
duct 14, namely tangent circles 143, 144 and 145. The tangent circle 143 is a tangent
circle at the air inlet end 141, and is defined as an air inlet end tangent circle,
a diameter of which is D1; the tangent circle 145 is a middle tangent circle, a diameter
of which is D2; the tangent circle 144 is a tangent circle at the air outlet end 142,
and is defined as an air outlet end tangent circle, a diameter of which is D3. The
diameters satisfy the following relations: D3/D2=[1-(5-25%)], and D2/D1=[1-(5-25%)].
Preferably, D3/D2=[1-(10-20%)], D2/D1=[1-(10-20%)], and D3/D2≠D2/D1. In addition,
in this embodiment, the diameter D1 of the air inlet end tangent circle 143 and the
diameter D3 of the air outlet end tangent circle 144 further satisfy the following
relation: D3/D1=60-70%. More preferably, D3/D1=65%.
[0044] Similarly, there are also three tangent circles in the second circular heat-exchanged
air duct 15, namely, an air inlet end tangent circle proximal to an air inlet end
151, an air outlet end tangent circle 154 proximal to an air outlet end 152 and a
middle tangent circle 155 located in the middle, and a relationship of diameters of
the three tangent circles also satisfy the foregoing conditions.
[0045] Moreover, in this embodiment, a diameter of the air inlet end tangent circle 153
of the second circular heat-exchanged air duct 15 is greater than a diameter of the
air inlet end tangent circle 143 of the first circular heat-exchanged air duct 14,
and a diameter of the air outlet end tangent circle 154 of the second circular heat-exchanged
air duct 15 is greater than a diameter of the air outlet end tangent circle 144 of
the first circular heat-exchanged air duct 14. So that volumes of the heat-exchanged
air ducts satisfy a changing trend of reducing gradually in a direction from the non-heat-exchanged
air inlet 122 of the rear-end circular air guiding body 12 to the mixed air outlet
111 of the front-end circular air guiding body 11.
[0046] After the annular heat-exchanged air ducts are arranged according to the foregoing
structure, the direction of the heat-exchanged air may be changed, so that the heat-exchanged
air and the non-heat-exchanged air both are blown out along surfaces of annular air
guiding bodies, which effectively avoids problems that the air speed is reduced and
condensation occurs because two parts of air meets and collides at surfaces of non-annular
air guiding bodies in the through-duct.
[0047] Refer to the schematic structural rear view of FIG. 7, the airflow distribution assembly
16 in this embodiment is implemented by using a plurality of airflow distribution
plates. In this embodiment, the airflow distribution assembly 16 totally includes
eight airflow distribution plates in pairs, namely, primary airflow distribution plates
161 and 162, first auxiliary airflow distribution plates 163 and 164, second auxiliary
airflow distribution plates 165 and 166, and third auxiliary airflow distribution
plates 167 and 168. All the airflow distribution plates are bent distribution plates
of the same bending direction, and the surface of each of the airflow distribution
plates is an arc-shaped curved surface, which can effectively guide the air, reduce
pressure loss and noise during splitting of the air flow, and achieve a high-speed
air supply at low noise. The four pairs of airflow distribution plates are arranged
bilaterally symmetrically in the circumferential direction of the first circular heat-exchanged
air duct 14 and the second circular heat-exchanged air duct 15 in such a manner that
the primary airflow distribution plates 161 and 162, the first auxiliary airflow distribution
plates 163 and 164, the second auxiliary airflow distribution plates 165 and 166,
and the third auxiliary airflow distribution plates 167 and 168 are sequentially arranged
from bottom to top. That is, in the air supply direction of the heat-exchanged air
that is from bottom to top, the primary airflow distribution plate 161, the first
auxiliary airflow distribution plate 163, the second auxiliary airflow distribution
plate 165 and the third auxiliary airflow distribution plate 167 are disposed from
bottom to top on the left side of the air-conditioner air supply apparatus 1 (in terms
of the left and right sides in the rear view), and the primary airflow distribution
plate 162, the first auxiliary airflow distribution plate 164, the second auxiliary
airflow distribution plate 166 and the third auxiliary airflow distribution plate
168 are arranged bilaterally symmetrically on the right side of the air-conditioner
air supply apparatus 1. In addition, the bending direction of each of the airflow
distribution plates is reverse to the air supply direction of the heat-exchanged air.
That is, the air supply direction of the heat-exchanged air is from bottom to top,
and accordingly, the bending direction of each of the airflow distribution plates
will be reverse to the air supply direction, that is, each of the airflow distribution
plates is bent in the anticlockwise direction shown in FIG. 7.
[0048] The airflow distribution assembly 16 formed by a plurality of bent airflow distribution
plates radially symmetrically arranged is disposed in the heat-exchanged air duct,
so that the primary airflow distribution plates 161 and 162 can be used to divide
the heat-exchanged air from the heat exchanger into left, middle and right parts,
and the heat-exchanged air on the left and right sides is further divided by the auxiliary
airflow distribution plates, uniform air intake and outtake in the circumferential
direction of the heat-exchanged air duct of the air-conditioner air supply apparatus
1 are finally achieved, thereby improving the uniformity of air supply from the air-conditioner
air supply apparatus 1.
[0049] Definitely, the airflow distribution assembly 16 may not necessarily be implemented
by a plurality of bent airflow distribution plates, and may also use other structures,
as long as the heat-exchanged air from the heat exchanger 5 can be uniformly distributed
in the circumferential direction.
[0050] The shape, area and position of each of the airflow distribution plates in the heat-exchanged
air duct are key factors affecting the uniformity of air supply. In this embodiment,
the pairs of airflow distribution plates are of the same shape and area. However,
for the plurality of airflow distribution plates on one side, from bottom to top,
the area of the primary airflow distribution plate 161 or 162 is greater than that
of the first auxiliary airflow distribution plate 163 or 164, the area of the first
auxiliary airflow distribution plate 163 or 164 is greater than that of the second
auxiliary airflow distribution plate 165 or 166, and the area of the second auxiliary
airflow distribution plate 165 or 166 is greater than that of the third auxiliary
airflow distribution plate 167 or 168.
[0051] Furthermore, because the density of air flow is not identical in the circumferential
direction, the airflow distribution plates on the same side are distributed at unequal
spacings. In particular, the length of an arc L2 between the primary airflow distribution
plate 161 or 162 and the first auxiliary airflow distribution plate 163 or 164 (indicating
the spacing between the two) is greater than the length of an arc L3 between the first
auxiliary airflow distribution plate 163 or 164 and the second auxiliary airflow distribution
plate 165 or 166, and the length of the arc L3 between the first auxiliary airflow
distribution plate 163 or 164 and the second auxiliary airflow distribution plate
165 or 166 is greater than the length of an arc L4 between the second auxiliary airflow
distribution plate 165 or 166 and the third auxiliary airflow distribution plate 167
or 168. Preferably, the ratio of the lengths of the arc L2, the arc L3 and the arc
L4 is 6:5:3.
[0052] Moreover, for the primary airflow distribution plates 161 and 162 disposed at a lower
part of the first circular heat-exchanged air duct 14 and the second circular heat-exchanged
air duct 15, the two circular heat-exchanged air ducts are divided into an upper part
and a lower part, the lower part being corresponding to the arc L1, and all other
arcs being the upper part. To ensure the uniformity of air supply in the circumferential
direction, the ratio of the length of the arc L1 corresponding to the lower part to
the length of the arcs of the upper part (not marked in the figure, which are arcs
in the entire circumferential direction other than L1) is 1:2 to 1:4. The third auxiliary
airflow distribution plates 167 and 168 at the top of the two circular heat-exchanged
air ducts define an arc L5 at the top, and the length of the arc L5 accounts for 1/5
to 1/3 of the total circumferential length of the first circular heat-exchanged air
duct 14 or the second circular heat-exchanged air duct 15.
[0053] The shape, area and position of each of the airflow distribution plates in the heat-exchanged
air duct are designed properly to make the heat-exchanged air to enter the heat-exchanged
air duct uniformly in the circumferential direction, thereby improving the uniformity
of air supply from the air-conditioner air supply apparatus.

the art can still make modifications to the technical solutions described in the foregoing
