Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner and a control method of the air conditioner. Background Art

[0002] Air conditioner is an air conditioner, which is a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. Nowadays, in addition to the basic functions of cooling and heating, the comfort of air supply is also increasingly valued. Whether in the process of cooling or heating, if the wind with cold or hot air blows directly on people, people will feel strong and uncomfortable wind, and the hardness of the cold wind makes the comfort of air supply of the air conditioner worse.

[0003] In order to improve the comfort of air supply from the air conditioner, a soft wind structure is provided at the air outlet of the existing air conditioner. As the air flow after heat exchange is discharged from the air outlet, the driving control mechanism of the soft wind structure drives the soft wind component to rotate around the normal direction of the air induced draft plate. Since the soft wind blades of the soft wind component extend spirally around the normal direction of the air induced draft plate, when the air flow at the air outlet flows through the soft wind blades, the soft wind blades extending spirally around the normal direction of the air induced draft plate and rotating around the normal direction of the air induced draft plate can disturb the air flow at the air outlet, thereby reducing the wind feeling, softening the air flow delivered into the room, and achieving a windless air supply effect.

[0004] However, the soft wind structure provided at the air outlet of the existing air conditioner can only disturb the airflow at the air outlet to realize the windless soft wind air supply working mode. The working mode is single and cannot meet the user's multi-functional air supply working mode requirements. Summary of the invention

[0005] The first object of the present invention is to provide an air conditioner that can execute any working mode of conventional air supply mode, compound soft wind mode, soft wind diffusion mode, and large air volume air supply mode. The working mode has diverse optionality to meet the user's multi-functional air supply working mode requirements, and can increase the air volume and comfort of the air supply, thereby enhancing the user experience comfort.

[0006] A second object of the present invention is to provide a control method for the above air conditioner.

[0007] In order to achieve the first object of the present invention, the present invention provides an air conditioner, including a casing and an air inlet structure, the casing is provided with an air inlet and an air outlet, the air inlet is located above the air outlet in the vertical direction, the air inlet structure includes a rotation control mechanism, an air inlet plate and an axial flow fan, the air inlet plate is located outside the casing, the rotation control mechanism can control the air inlet plate to rotate around the length direction of the casing, and the air inlet plate is provided with ventilation holes in the normal direction thereof, the axial flow fan blades of the axial flow fan are located in the ventilation holes, and the motor of the axial flow fan can control the rotation of the axial flow fan blades; the air inlet structure is in any one of the conventional air supply mode, the composite soft wind mode, the soft wind diffusion mode and the large air volume air supply mode Working mode; when the induced draft structure is in the conventional air supply mode, the induced draft plate is away from the air outlet, and the axial flow fan blades stop rotating; when the induced draft structure is in the composite soft wind mode, the induced draft plate is located below the air outlet in the vertical direction and is arranged close to the air outlet, and the axial flow fan blades are reversed to blow the indoor airflow upward and mix it with the heat exchange airflow blown out of the air outlet and then send it into the room together; when the induced draft structure is in the soft wind diffusion mode, the induced draft plate is arranged opposite to the air outlet, and the axial flow fan blades rotate forward to diffuse the heat exchange airflow blown out of the air outlet into the room; when the induced draft structure is in the large air volume supply mode, the induced draft plate is arranged opposite to the air inlet, and the axial flow fan blades are reversed to send the indoor airflow into the air inlet.

[0008] It can be seen from the above scheme that when the air induced draft structure of the air conditioner of the present invention performs the conventional air supply mode, the rotation control mechanism controls the air induced draft plate to rotate around the length direction of the casing so that the air induced draft plate drives the axial flow fan away from the air outlet, and the motor of the axial flow fan stops controlling the rotation of the axial flow fan blades, so that the axial flow fan blades stop rotating, so that under the action of the cross-flow impeller of the air conditioner, the indoor airflow enters the casing from the air inlet of the casing, and passes through the evaporator for heat exchange, and then the heat exchanged airflow is sent into the room from the air outlet of the casing, and the conventional air supply mode is operated reciprocatingly and sequentially. At this time, the air induced draft structure is in a reset non-working state.

[0009] When the draft structure of the air conditioner of the present invention performs the composite soft wind mode, the rotation control mechanism controls the draft plate to rotate around the length direction of the casing so that the draft plate drives the axial flow fan to be located below the air outlet in the vertical direction and close to the air outlet, and the motor of the axial flow fan controls the axial flow fan blade to reverse so as to blow the indoor airflow upward and mix it with the heat exchange airflow blown out of the air outlet and then send it into the room together. Since the indoor airflow located below the casing has uneven heat exchange, the draft structure of the air conditioner of the present invention can blow the indoor airflow below the casing upward and mix it with the heat exchange airflow blown out of the air outlet and then send it into the room together when performing the composite soft wind mode. On the one hand, it can improve the heat exchange effect and heat exchange uniformity of the indoor airflow, and on the other hand, it can reduce the hardness of the air supply and improve the user experience comfort.

[0010] When the air induced structure of the air conditioner of the present invention performs the soft wind diffusion mode, the rotation control mechanism controls the air induced plate to rotate around the length direction of the casing so that the air induced plate drives the axial flow fan to be arranged relative to the air outlet, and the motor of the axial flow fan controls the axial flow fan blades to rotate forward to diffuse the heat exchange airflow blown out of the air outlet into the room. Since when the air induced structure of the present invention performs the soft wind diffusion mode, the axial flow fan is arranged relative to the air outlet, and the axial flow fan blades rotate forward to diffuse the heat exchange airflow blown out of the air outlet into the room, the axial flow fan blades can disperse and soften the heat exchange airflow blown out of the air outlet, and achieve a windless air supply effect while disturbing and dispersing the air outlet direction, thereby improving the user experience comfort.

[0011] When the draft structure of the air conditioner of the present invention performs a high-volume air supply mode, the rotation control mechanism controls the draft plate to rotate around the length direction of the casing so that the draft plate drives the axial flow fan to be arranged relative to the air inlet, and the motor of the axial flow fan controls the axial flow fan blades to reverse to deliver the indoor airflow into the air inlet. Since the draft structure of the present invention performs a high-volume air supply mode, the axial flow fan blades can assist the air intake at the air inlet, so that the air intake volume is increased while the air intake speed is also increased, and after being accelerated again by the cross-flow impeller, a large air volume can be delivered to the room from the air outlet, thereby improving the heat exchange efficiency of the indoor airflow, and further improving the user experience comfort.

[0012] Therefore, the air conditioner of the present invention can execute any working mode of conventional air supply mode, compound soft wind mode, soft wind diffusion mode, and large air volume air supply mode. The working mode has diverse options to meet the user's multi-functional air supply working mode requirements, and can increase the air volume and comfort of the air supply, thereby improving the user experience comfort.

[0013] A preferred solution is that the air induced draft plate is provided with at least two ventilation holes, the plurality of ventilation holes are arranged side by side in the length direction of the casing, and the number of axial flow fans is at least two, and the axial flow blades of one axial flow fan are located in one ventilation hole.

[0014] A further solution is that the air conditioner further comprises an air guide plate, which is rotatably arranged at the air outlet around the length direction of the casing to open or close the air outlet.

[0015] A further solution is that the air induced draft plate is provided with rotating arms on both sides of the casing in the length direction, the two rotating arms are rotatably supported on both sides of the casing in the length direction, and the rotation control mechanism can control the two rotating arms to rotate synchronously around the length direction of the casing.

[0016] To achieve the second object of the present invention, the present invention provides a control method for an air conditioner, which uses the above-mentioned air conditioner, and an infrared thermal energy monitor is provided on the casing of the air conditioner. The control method of the air conditioner includes: the infrared thermal energy monitor obtains the real-time indoor heat M; when M≤M1, the air guiding structure of the air conditioner is controlled to execute the conventional air supply mode; when M>M1, the air guiding structure is controlled to execute the large air volume air supply mode; M1 is the first preset heat.

[0017] A further solution is that a temperature sensor is provided on the casing, and the control method of the air conditioner further includes: after satisfying M>M1, the temperature sensor obtains the real-time indoor temperature T; when |T-T0|≤T1, the air guiding structure is controlled to execute the composite soft air mode; T0 is the preset target temperature of the air conditioner, and T1 is the first preset deviation temperature.

[0018] A further solution is that the control method of the air conditioner further includes: determining whether |T-T0|≤T2 is satisfied. If satisfied, the air guiding structure is controlled to execute the soft air diffusion mode, where T2 is the second preset deviation temperature, and the second preset deviation temperature T2 is less than the first preset deviation temperature T1; or, determining whether the following two conditions are simultaneously satisfied: M1<M≤M2 and the real-time indoor temperature T satisfies the preset sleep temperature. If both are satisfied, the air guiding structure is controlled to execute the soft air diffusion mode, where M2 is the second preset heat.

[0019] A further solution is that the preset sleep temperature is T p and 30°C≤T p ≤34°C.

[0020] A further solution is that the first preset heat M1 = 50W; and / or, the second preset heat M2 = 100W; and / or, the first preset deviation temperature T1 = 4°C; and / or, the second preset deviation temperature T2 = 2°C.

[0021] A further solution is that the air conditioner further includes a deflector, and the deflector is rotatably arranged at the air outlet of the casing around the length direction of the casing to open or close the air outlet. The air outlet is inclined upward from bottom to top relative to the horizontal direction towards the front panel of the casing; when the air guiding structure executes the composite soft air mode, the deflector rotates clockwise by a first preset angle θ1 relative to the air outlet, and 0<θ1≤90°; and / or, when the air guiding structure executes the soft air diffusion mode, the deflector rotates clockwise by a second preset angle θ2 relative to the air outlet, and θ2≥90°.

[0035] Air conditioner embodiment:

[0036] See also Figures 1 to 5The present embodiment discloses an air conditioner 10, including a housing 11 and an air inlet structure 13. The housing 11 is provided with an air inlet 112 and an air outlet 113. The air inlet 112 is located above the air outlet 113 in the vertical direction. The air inlet structure 13 of the present embodiment includes a rotation control mechanism, an air inlet plate 131 and an axial flow fan. The air inlet plate 131 is located outside the housing 11. The rotation control mechanism can control the air inlet plate 131 to rotate around the length direction 111 of the housing 11. The air inlet plate 131 is provided with a ventilation hole 1311 in the normal direction thereof. The axial flow blades 132 of the axial flow fan are located in the ventilation hole 1311. The motor of the axial flow fan is arranged on the air inlet plate 131 and can control the rotation of the axial flow blades 132. In addition, the air inlet structure 13 of the present embodiment is in any working mode of the conventional air supply mode, the compound soft wind mode, the soft wind diffusion mode, and the large air volume air supply mode. Specifically, when the draft structure 13 is in the conventional air supply mode, the draft plate 131 is away from the air outlet 113, and the axial flow fan blades 132 stop rotating; when the draft structure 13 is in the composite soft wind mode, the draft plate 131 is located below the air outlet 113 in the vertical direction and is arranged close to the air outlet 113, and the axial flow fan blades 132 are reversed to blow the indoor airflow upward and mix it with the heat exchange airflow blown out of the air outlet 113 and then send it into the room together; when the draft structure 13 is in the soft wind diffusion mode, the draft plate 131 is arranged opposite to the air outlet 113, and the axial flow fan blades 132 rotate forward to diffuse the heat exchange airflow blown out of the air outlet 113 into the room; when the draft structure 13 is in the large air volume supply mode, the draft plate 131 is arranged opposite to the air inlet 112, and the axial flow fan blades 132 are reversed to send the indoor airflow into the air inlet 112.

[0037] When the air induced draft structure 13 of the air conditioner 10 of this embodiment executes the conventional air supply mode, the rotation control mechanism controls the air induced draft plate 131 to rotate around the length direction 111 of the casing 11 so that the air induced draft plate 131 drives the axial flow fan away from the air outlet 113, and the motor of the axial flow fan stops controlling the rotation of the axial flow fan blades 132, so that the axial flow fan blades 132 stop rotating, so that under the action of the cross-flow impeller 15 of the air conditioner 10, the indoor airflow enters the casing 11 from the air inlet 112 of the casing 11, and exchanges heat through the evaporator 14, and then the heat exchanged airflow is sent into the room from the air outlet 113 of the casing 11, and the conventional air supply mode is operated reciprocatingly and sequentially. At this time, the air induced draft structure 13 is in a reset non-working state.

[0038] When the air induction structure 13 of the air conditioner 10 of the present embodiment performs the composite soft wind mode, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the casing 11 so that the air induction plate 131 drives the axial flow fan to be located below the air outlet 113 in the vertical direction and close to the air outlet 113, and the motor of the axial flow fan controls the axial flow blades 132 to reverse so as to blow the indoor air flow upward and mix it with the heat exchange air flow blown out of the air outlet 113 and then send it into the room together, see Figure 6 and Figure 7 As shown. Since the indoor airflow below the casing 11 has uneven heat exchange, the air induction structure 13 of the air conditioner 10 of this embodiment can blow the indoor airflow below the casing 11 upwards and mix it with the heat exchange airflow blown out of the air outlet 113 and send them into the room together when executing the composite soft wind mode. On the one hand, it can improve the heat exchange effect and heat exchange uniformity of the indoor airflow, and on the other hand, it can reduce the hardness of the air supply and improve the user experience comfort.

[0039] When the air induction structure 13 of the air conditioner 10 of the present embodiment performs the soft wind diffusion mode, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the casing 11 so that the air induction plate 131 drives the axial flow fan to be arranged opposite to the air outlet 113, and the motor of the axial flow fan controls the axial flow fan blades 132 to rotate forward to diffuse the heat exchange airflow blown out of the air outlet 113 into the room, see Figure 8 and Fig. 9 As shown. When the air induction structure 13 of this embodiment performs the soft wind diffusion mode, the axial flow fan is arranged opposite to the air outlet 113, and the axial flow fan blades 132 rotate forward to diffuse the heat exchange airflow blown out of the air outlet 113 to the room. The axial flow fan blades 132 can disperse and soften the heat exchange airflow blown out of the air outlet 113, and achieve a windless air supply effect while disturbing and dispersing the airflow and changing the air outlet direction, thereby improving the user experience comfort.

[0040] When the air induction structure 13 of the air conditioner 10 of the present embodiment performs a large air volume supply mode, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the housing 11 so that the air induction plate 131 drives the axial flow fan to be arranged opposite to the air inlet 112, and the motor of the axial flow fan controls the axial flow blades 132 to reverse to deliver the indoor air flow into the air inlet 112, see Fig.10 and Fig.11 When the air induction structure 13 of this embodiment performs the large air volume supply mode, the axial flow fan blades 132 can assist the air intake at the air inlet 112, so that the air volume is increased and the air velocity is also increased, and after being accelerated again by the cross-flow impeller 15, a large air volume can be supplied to the room through the air outlet 113, thereby improving the heat exchange efficiency of the indoor air flow and further improving the user experience comfort.

[0041] Therefore, the air conditioner 10 in this embodiment can execute any working mode of the conventional air supply mode, the compound soft wind mode, the soft wind diffusion mode, and the large air volume air supply mode. The working mode has diverse options to meet the user's multi-functional air supply working mode requirements, and can increase the air volume and comfort of the air supply, thereby improving the user experience comfort.

[0042] In order to further improve the working stability and reliability of the air induction structure 13, the air induction plate 131 of this embodiment is provided with at least two ventilation holes 1311, and the multiple ventilation holes 1311 are arranged side by side in the length direction 111 of the casing 11, and the number of axial flow fans is at least two, and the axial flow blades 132 of an axial flow fan are located in one ventilation hole 1311.

[0043] In order to improve the stability and reliability of the rotation of the air induction plate 131, the air induction plate 131 of this embodiment is respectively provided with rotating arms 1312 on both sides of the length direction 111 of the housing 11, and the two rotating arms 1312 are rotatably supported on both sides of the housing 11 in the length direction 111 of the housing 11, and the rotation control mechanism can control the two rotating arms 1312 to rotate synchronously around the length direction 111 of the housing 11. Specifically, the rotation control mechanism of this embodiment is a driving motor, and the driving motor can control the two rotating arms 1312 to rotate synchronously around the length direction 111 of the housing 11.

[0044] In order to further improve air supply efficiency and comfort, the air conditioner 10 of this embodiment further includes an air guide plate 12, which is rotatably arranged at the air outlet 113 around the length direction 111 of the casing 11 to open or close the air outlet 113. Specifically, the air outlet 113 of this embodiment is inclined from bottom to top relative to the horizontal direction toward the front panel 114 of the casing 11, so as to better supply air to the indoor space.

[0045] In order to improve the intelligent control of the air conditioner 10, the housing 11 of the air conditioner 10 in this embodiment is provided with an infrared heat energy monitor and a temperature sensor. The infrared heat energy monitor is used to detect the real-time indoor heat, and the temperature sensor is used to detect the real-time indoor temperature.

[0046] Embodiment of the control method of air conditioner:

[0047] The control method of the air conditioner of this embodiment uses the air conditioner 10 of the above embodiment. The control method of the air conditioner 10 of this embodiment includes receiving a signal sent by a remote controller, etc., and executing the following specific steps.

[0048] First, step S1 is executed to execute a power-on instruction and set a preset target temperature T0 of the air conditioner 10 .

[0049] Then, step S2 is executed, the infrared heat energy monitor obtains the real-time indoor heat M, and the temperature sensor obtains the real-time indoor temperature T.

[0050] Then, step S3 is executed to determine whether M≤M1 is satisfied, where M1 is the first preset heat. When it is determined that M≤M1 is satisfied, it means that the heat detected by the infrared heat energy monitor at this time only comes from the reflection of the indoor wall and indoor objects, and there is no obvious heat source in the room at this time, then step S4 is executed to control the air induction structure 13 of the air conditioner 10 to execute the conventional air supply mode, that is, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the casing 11 so that the air induction plate 131 drives the axial flow fan away from the air outlet 113, and the motor of the axial flow fan stops controlling the rotation of the axial flow blade 132, so that the axial flow blade 132 stops rotating, so that under the action of the cross-flow impeller 15 of the air conditioner 10, the indoor airflow enters the casing 11 from the air inlet 112 of the casing 11, and exchanges heat through the evaporator 14, and then the heat exchange airflow is sent into the room from the air outlet 113 of the casing 11, and the conventional air supply mode is operated reciprocatingly and sequentially, and the air induction structure 13 is in a reset non-working state.

[0051] When it is judged that M≤M1 is not satisfied, that is, it is judged that M>M1 is satisfied, which means that the heat detected by the infrared thermal energy monitor at this time is not only reflected from the indoor walls and indoor objects, but also emitted by other indoor heat sources, including electronic heat dissipation equipment such as computers and heat dissipation of people sitting still, working, light exercise and other active states, then step S5 is executed to control the air induced structure 13 of the air conditioner 10 to execute a large air volume air supply mode, that is, the rotation control mechanism controls the air induced plate 131 to rotate around the length direction 111 of the casing 11 so that the air induced plate 131 drives the axial flow fan to be arranged relative to the air inlet 112, and the motor of the axial flow fan controls the axial flow fan blades 132 to reverse to send the indoor air flow into the air inlet 112, see Fig.10 and Fig.11 When the air induction structure 13 of this embodiment performs the large air volume supply mode, the axial flow fan blades 132 can assist the air intake at the air inlet 112, so that the air volume is increased and the air velocity is also increased, and after being accelerated again by the cross-flow impeller 15, a large air volume can be supplied to the room through the air outlet 113, thereby improving the heat exchange efficiency of the indoor air flow and further improving the user experience comfort.

[0052] Then, step S6 is executed to determine whether |T-T0|≤T1 is satisfied, where T1 is the first preset deviation temperature. When it is determined that |T-T0|≤T1 is satisfied, it indicates that the preliminary temperature control of the indoor airflow has been achieved, and step S7 is executed to control the air induction structure 13 of the air conditioner 10 to execute the composite soft wind mode, that is, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the casing 11 so that the air induction plate 131 drives the axial flow fan to be located below the air outlet 113 in the vertical direction and close to the air outlet 113, and the motor of the axial flow fan controls the axial flow blades 132 to reverse so that the indoor airflow is blown upward and mixed with the heat exchange airflow blown out of the air outlet 113 and sent into the room together, see Figure 6 and Figure 7 As shown. Since the indoor airflow below the casing 11 has uneven heat exchange, the air induction structure 13 of the air conditioner 10 of this embodiment can blow the indoor airflow below the casing 11 upwards and mix it with the heat exchange airflow blown out of the air outlet 113 and send them into the room together when executing the composite soft wind mode. On the one hand, it can improve the heat exchange effect and heat exchange uniformity of the indoor airflow, and on the other hand, it can reduce the hardness of the air supply and improve the user experience comfort.

[0053] In order to further improve air supply efficiency and comfort, the control method of the air conditioner 10 in this embodiment controls the air guide plate 12 to rotate clockwise by a first preset angle θ1 relative to the air outlet 113 when controlling the air induction structure 13 to execute the compound soft wind mode, and 0<θ1≤90°.

[0054] When it is determined that |T-T0|≤T1 is not satisfied, it means that the initial temperature of the indoor airflow has not reached the expected level, and step S5 is continued.

[0055] After executing step S7 and the air induction structure 13 of the air conditioner 10 executes the compound soft wind mode, steps S8 and S9 can be executed simultaneously. As long as one of the judgment conditions in steps S8 and S9 is met, step S10 can be executed.

[0056] Execute step S8 to determine whether |T-T0|≤T2 is satisfied, where T2 is the second preset deviation temperature, and the second preset deviation temperature T2 is less than the first preset deviation temperature T1. When it is determined that |T-T0|≤T2 is satisfied, it means that the preset target temperature control of the indoor airflow has been basically achieved, and then execute step S10 to control the air induction structure 13 of the air conditioner 10 to execute the soft wind diffusion mode, that is, the rotation control mechanism controls the air induction plate 131 to rotate around the length direction 111 of the casing 11 so that the air induction plate 131 drives the axial flow fan to be arranged opposite to the air outlet 113, and the motor of the axial flow fan controls the axial flow blades 132 to rotate forward to diffuse the heat exchange airflow blown out of the air outlet 113 into the room, see Figure 8 and Fig. 9 As shown. When the air induction structure 13 of this embodiment performs the soft wind diffusion mode, the axial flow fan is arranged opposite to the air outlet 113, and the axial flow fan blades 132 rotate forward to diffuse the heat exchange airflow blown out of the air outlet 113 to the room. The axial flow fan blades 132 can disperse and soften the heat exchange airflow blown out of the air outlet 113, and achieve a windless air supply effect while disturbing and dispersing the airflow to change the direction of the airflow, thereby improving the user experience comfort. When it is judged that |T-T0|≤T2 is not satisfied, it means that the temperature control of the indoor airflow has not yet reached the preset target, and then continue to execute step S7.

[0057] In order to further improve the air supply efficiency and comfort, when the control method of the air conditioner 10 in this embodiment controls the air guiding structure 13 to execute the gentle wind diffusion mode, the air deflector 12 is synchronously controlled to rotate clockwise by a second preset angle θ2 relative to the air outlet 113, and θ2≥90°.

[0058] Execute step S9 to determine whether the following two conditions are simultaneously satisfied: M1<M≤M2 and the indoor real-time temperature T satisfies the preset sleep temperature, where M2 is the second preset heat quantity. When it is determined that the following two conditions are satisfied: M1<M≤M2 and the indoor real-time temperature T satisfies the preset sleep temperature, that is, when the two conditions are simultaneously satisfied, it indicates that the human body is in a sleeping state, then execute step S10 to control the air guiding structure 13 of the air conditioner 10 to execute the gentle wind diffusion mode to achieve the windless feeling air supply effect. When it is determined that the following two conditions are not simultaneously satisfied: M1<M≤M2 and the indoor real-time temperature T satisfies the preset sleep temperature, then continue to execute step S7. Specifically, the preset sleep temperature in this embodiment is T p , and 30°C≤T p ≤34°C.

[0059] Specifically, in this embodiment, the first preset heat quantity M1 = 50W, the second preset heat quantity M2 = 100W, the first preset deviation temperature T1 = 4°C, and the second preset deviation temperature T2 = 2°C.

[0060] The above embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics, and principles of the patent application scope of the present invention should be included within the scope of the patent application of the present invention.
