Description

Technical Field

[0001] The present invention relates to an indoor unit of an air conditioner, in particular to an indoor unit of an air conditioner. Background Art

[0002] With the development of human society, users have higher demands on the aesthetics, self-cleaning function and ease of use of air conditioners.

[0003] Currently, conventional air conditioner indoor units are designed with false air vents, which increase the air outlet of the air conditioner indoor unit and make the air outlet of the air conditioner indoor unit bilaterally symmetrical and more aesthetically pleasing. However, since the false air vents are blocked by internal components of the air conditioner indoor unit (e.g., a housing enclosing electronic control components), during normal cooling, no cold air is blown out from the false air vents, and no cooling air flows through the portion of the air guide plate corresponding to the false air vents. This causes the portion of the air guide plate corresponding to the false air vents and the portion with cooling air flowing through to converge, and stagnant room-temperature humid air exists between the false air vents and the portion of the air guide plate corresponding to the false air vents, which easily leads to condensation of water at the guide plate portion corresponding to the false air vents. Summary of the Invention

[0004] An object of the present invention is to provide an air conditioner indoor unit that overcomes any of the drawbacks of the prior art.

[0005] A further object of the present invention is to effectively limit the generation of condensation water on the air guide plate.

[0006] Another further object of the present invention is to effectively avoid interference of the guide component with the direction and flow of the air flow out of the air conditioner indoor unit when the air conditioner indoor unit operates in a mode other than the cooling mode, thereby ensuring the normal operation of the air conditioner indoor unit.

[0007] Yet another further object of the present invention is to effectively limit the generation of condensation water at the shielding section.

[0008] A further object of the present invention is to clean the dust accumulated in the shielding.

[0009] In particular, the present invention provides an air conditioner indoor unit, comprising:

[0010] The housing is provided with an air outlet extending along its length, the air outlet comprising an air supply section located downstream of the air supply duct and a shielding section located at one end of the air supply section and shielded by internal components of the air conditioner indoor unit;

[0014] The driving mechanism is arranged on the air guide plate and is used for driving the flow guiding member to be in the first state or the second state.

[0019] The drive mechanism is configured as follows:

[0020] When the accumulation amount is greater than or equal to a predetermined value, the drainage member is driven to be in the first state;

[0021] When the accumulation amount is less than a predetermined value, driving the drainage member to be in the second state; and

[0022] The supply air fans are configured as:

[0023] When the accumulation amount is greater than or equal to a predetermined value, the speed of the air supply fan is a first speed value;

[0024] When the accumulation amount is less than a predetermined value, the rotational speed of the air supply fan is a second rotational speed value; wherein the first rotational speed value is greater than the second rotational speed value.

[0025] Furthermore, the drainage member is a curved arc structure;

[0026] The curvature of the portion of the flow guiding member corresponding to the air supply section is greater than the curvature of the portion of the flow guiding member corresponding to the shielding section.

[0027] Furthermore, the accommodating portion is an accommodating hole communicating with the inner side surface of the air deflector and the outer side surface of the air deflector;

[0028] The drainage components include:

[0029] The first deflector plate has a state of protruding from the inner side surface of the air guide plate and a state of being accommodated in the accommodation portion;

[0030] The second guide plate has a state of protruding from the outer side surface of the air guide plate and a state of being accommodated in the accommodating portion.

[0031] Furthermore, a first limiting protrusion and a second limiting protrusion are provided on the side wall of the accommodating hole; and,

[0032] A third limiting protrusion is provided on the first guide plate, and a fourth limiting protrusion is provided on the second guide plate;

[0033] In the first state, the third limiting protrusion abuts against the first limiting protrusion, and the fourth limiting protrusion abuts against the second limiting protrusion.

[0034] Furthermore, the driving mechanism includes:

[0035] an electromagnet disposed in the receiving hole and between the first guide plate and the second guide plate, the electromagnet having a first magnetic pole and a second magnetic pole of opposite magnetic properties; and

[0036] A third magnetic pole is provided on the end of the first guide plate corresponding to the first magnetic pole, and a fourth magnetic pole is provided on the end of the second guide plate corresponding to the second magnetic pole. The magnetic properties of the third magnetic pole and the fourth magnetic pole are opposite.

[0037] Further, the electromagnet is an electromagnet;

[0038] The electromagnet is configured such that the first pole and the third pole have the same magnetic properties and the second pole and the fourth pole have the same magnetic properties;

[0039] The electromagnet is further configured such that the first magnetic pole and the third magnetic pole have opposite magnetic properties and the second magnetic pole and the fourth magnetic pole have opposite magnetic properties; or, the electromagnet is further configured to be in a power-off state.

[0040] Furthermore, the total thickness of the first guide plate, the second guide plate and the electromagnet is the same as the thickness of the air guide plate.

[0041] Furthermore, the air conditioner indoor unit further comprises:

[0042] A humidity sensor is connected to the driving mechanism and is used to obtain the ambient humidity of the indoor space where the indoor unit of the air conditioner is used; and

[0043] The drive mechanism is configured as follows:

[0044] When the ambient humidity is greater than or equal to a preset value, the drainage member is driven to be in the first state;

[0045] When the ambient humidity is less than a preset value, the drainage member is driven to be in the first state.

[0046] The indoor unit of the air conditioner of the present invention has a flow guide member that can guide the outlet air flow to flow through the portion corresponding to the air guide plate and the shielding section, thereby making the temperature distribution on the air guide plate uniform when the indoor unit of the air conditioner is operating in the cooling mode, so that there is no room temperature humid air in the portion corresponding to the air guide plate and the shielding section, effectively avoiding the situation where hot and cold air meet on the air guide plate. Therefore, the air conditioner of the present invention can effectively limit the generation of condensed water on the air guide plate. Moreover, since the flow guide member in the indoor unit of the air conditioner of the present invention can be accommodated in the accommodation portion by being driven by the driven mechanism, when there is no need to limit the generation of condensed water on the air guide plate, or when the indoor unit of the air conditioner is operating in the heating mode or other modes, the flow guide member will not interfere with the flow direction and flow rate of the outlet air flow of the indoor unit of the air conditioner, thereby ensuring the normal operation of the indoor unit of the air conditioner.

[0047] Furthermore, in the air conditioner indoor unit of the present invention, since one end of the flow guide member extends from the air inlet end of the air guide plate to the portion corresponding to the air supply section, and the other end of the flow guide member extends from the air inlet end of the air guide plate to the portion corresponding to the shielding section, and the middle portion of the flow guide member protrudes and extends toward the air outlet end of the air guide plate, by setting such a shape structure or extension direction of the flow guide member, the flow guide member can guide the outlet airflow to the internal components of the air conditioner indoor unit, and then make the outlet airflow flow through the shielding section, blow away the room temperature humid air in the shielding section, so that the temperature of the entire air outlet is uniform and there will be no intersection of cold and hot air. Therefore, the air conditioner indoor unit of the present invention effectively limits the generation of condensed water at the shielding section. At the same time, the outlet airflow flows through the shielding section and can also blow away the dust accumulated at the shielding section, playing the role of dust removal and cleaning, and ensuring the convenience of use of the air conditioner indoor unit.

Figure 8 FIG. 1 is a schematic connection block diagram of an indoor unit of an air conditioner according to an embodiment of the present invention.

[0065] Reference Figure 1 、 Figure 3 and Figure 6 In this embodiment, the air conditioner indoor unit includes a housing 100 and an air guide assembly. The housing 100 defines an air outlet 120 extending along its length. The air outlet 120 includes an air supply section 121 located downstream of the air supply duct 110 and a shielding section 122 located at one end of the air supply section 121 and shielded by the internal components 800 of the air conditioner indoor unit. The air guide assembly includes an air guide plate 200, a flow guide member 300, and a drive mechanism 400. The air guide plate 200 is rotatably arranged at the air outlet 120, and a accommodating portion 210 is provided on the side of the air guide plate 200; the flow guiding component 300 is arranged in the accommodating portion 210, and the flow guiding component 300 has a first state protruding from the side of the air guide plate 200 and a second state accommodated in the accommodating portion 210, and the flow guiding component 300 is used to guide the outlet air flow through the part of the air guide plate 200 corresponding to the shielding section 122 in the first state; the driving mechanism 400 is arranged on the air guide plate 200, and the driving mechanism 400 is used to drive the flow guiding component 300 to be in the first state or the second state.

[0066] Because the air conditioner of this embodiment includes a flow guide member 300 that guides the outlet airflow through the portion of the air guide plate 200 corresponding to the shielding section 122, the temperature distribution on the air guide plate 200 is uniform when the air conditioner indoor unit is operating in cooling mode. This eliminates the presence of room-temperature humid air in the portion of the air guide plate 200 corresponding to the shielding section 122, effectively preventing the confluence of hot and cold air on the air guide plate 200. Therefore, the air conditioner of this embodiment can effectively limit the formation of condensation on the air guide plate 200. Furthermore, because the flow guide member 300 in the air conditioner indoor unit of this embodiment can be accommodated within the accommodating portion 210 by being driven by the drive mechanism 400, when limiting the formation of condensation on the air guide plate 200 is not required, or when the air conditioner is operating in heating mode or other modes, the flow guide member 300 does not interfere with the direction and flow rate of the outlet airflow of the air conditioner indoor unit, thereby ensuring the normal operation of the air conditioner indoor unit.

[0067] In the prior art, to prevent condensation on the air deflector 200, the air deflector 200 is placed directly in the air duct. While this method can prevent condensation on the air deflector 200, since the false air vents do not release air, a zone of humid air at room temperature still exists at the false air vents (for example, the housing surrounding the electronic control components or the sidewalls of the false air vents). This creates a confluence of hot and cold air between the air supply area of the air supply vents and the false air vents, thus still presenting the risk of condensation. Furthermore, placing the air deflector 200 within the air duct increases the resistance to air flow within the duct.

[0068] Moreover, when the indoor unit of the air conditioner is used for a long time, there will be no airflow outflow at the false air vent, which will cause dust to accumulate (for example, the shell that wraps the electronic control components and the side walls of the false air vent). Even if the air guide plate 200 is built into the air duct, this defect cannot be overcome.

[0069] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, one end of the flow-guiding member 300 extends from the air inlet end of the air guide plate 200 to the part corresponding to the air supply section 121, and the other end of the flow-guiding member 300 extends from the air inlet end of the air guide plate 200 to the part corresponding to the shielding section 122. The middle part of the flow-guiding member 300 protrudes and extends toward the air outlet end of the air guide plate 200. The flow-guiding member 300 is also used to guide the outlet airflow to the internal component 800 in the first state.

[0070] Due to the aforementioned shape, structure, or extension direction of the air-conditioning indoor unit of this embodiment, the air-conditioning indoor unit can guide the outlet airflow toward the internal components 800 of the air-conditioning indoor unit, thereby allowing the outlet airflow to flow through the shielding section 122, blowing away the room-temperature humid air within the shielding section 122, and ensuring that the temperature of the entire air outlet 120 is uniform without the intersection of hot and cold air. Therefore, the air-conditioning indoor unit of this embodiment effectively limits the formation of condensed water in the shielding section 122. At the same time, the outlet airflow flowing through the shielding section 122 can also blow away the dust accumulated in the shielding area, performing a dust removal and cleaning function, and ensuring the convenience of use of the air-conditioning indoor unit. Furthermore, it will not affect the flow of the airflow within the air supply duct 110, nor will it create wind resistance to the outlet airflow.

[0071] Reference Figure 8In this embodiment, the indoor unit of the air conditioner further includes an air supply fan 500 and a dust sensor 600. The air supply fan 500 is disposed in the housing 100; the dust sensor 600 is connected to the air supply fan 500 and the driving mechanism 400, and the dust sensor 600 is used to obtain the amount of dust accumulated at the shielding section 122; and the driving mechanism 400 is configured to: when the accumulation amount is greater than or equal to a predetermined value, drive the flow guide member 300 to a first state; when the accumulation amount is less than the predetermined value, drive the flow guide member 300 to a second state; and the air supply fan 500 is configured to: when the accumulation amount is greater than or equal to the predetermined value, the rotation speed of the air supply fan 500 is a first rotation speed value; when the accumulation amount is less than the predetermined value, the rotation speed of the air supply fan 500 is a second rotation speed value; wherein the first rotation speed value is greater than the second rotation speed value.

[0072] It is understood that the dust sensor 600 is connected to the air blower 500 and the driving mechanism 400 through the controller 900. And the operation of the driving mechanism 400 and the air blower 500 can be controlled by the controller 900. This can realize the switching of the state of the guide member 300 and the adjustment of the speed of the air blower 500. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In the first state of the air guide member 300, dust accumulated in the shielding area can be blown away, achieving the dust removal and cleaning function. At the same time, the rotation speed of the air supply fan 500 is increased, further improving the air conditioner indoor unit's dust cleaning effect on the shielding section 122. At the same time, other functions or modes of the air conditioner indoor unit are guaranteed to operate when the dust cleaning function is not required.

[0073] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the flow guiding member 300 has a curved arc-shaped structure. This ensures minimal wind loss as the outgoing air flows through the flow guiding surface of the flow guiding member 300, effectively limiting condensation on the air guide plate 200 and the shielding section 122 and cleaning dust from the shielding section 122.

[0074] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the curvature of the portion of the air guiding member 300 corresponding to the air supply section 121 is greater than the curvature of the portion of the air guiding member 300 corresponding to the shielding section 122 .

[0075] It should be understood that when the outlet airflow flows from the air supply duct 110 to the guide member 300, the angle between the flow direction of the outlet airflow and the guide member 300 will affect the magnitude of the resistance to the outlet airflow. By making the portion of the guide member 300 corresponding to the air supply section 121 have a greater degree of curvature, the outlet airflow can be kept in the same direction before and after passing through the guide surface of the guide member 300, thereby reducing the wind loss of the outlet airflow when it flows into the guide member 300. In addition, the outlet airflow will also be subject to the wind resistance of the guide member 300 when it flows through the guide member 300 and has its direction changed. By making the portion of the guide member 300 corresponding to the shielding section 122 have a smaller degree of curvature, the flow direction of the outlet airflow can be changed as slowly as possible, thereby reducing the wind loss of the outlet airflow when it passes through the guide member 300. Therefore, by making the degree of curvature of the portion of the flow-guiding component 300 corresponding to the air supply section 121 greater than the degree of curvature of the portion of the flow-guiding component 300 corresponding to the shielding section 122, the flow rate of the air flow flowing through the portion of the air guide plate 200 corresponding to the shielding section 122 and the air flow flowing through the shielding section 122 or flowing to the internal component 800 can be ensured, thereby further ensuring the effect of limiting the generation of condensation water at the air guide plate 200 and the shielding section 122 and the effect of cleaning the dust at the shielding section 122.

[0076] Reference Figure 5 and Figure 6 In this embodiment, the accommodating portion 210 is an accommodating hole connecting the inner side surface of the air guide plate 200 and the outer side surface of the air guide plate 200; the guide member 300 includes a first guide plate 310 and a second guide plate 320, the first guide plate 310 has a state of protruding from the inner side surface of the air guide plate 200 and a state of being accommodated in the accommodating portion 210; the second guide plate 320 has a state of protruding from the outer side surface of the air guide plate 200 and a state of being accommodated in the accommodating portion 210.

[0077] Two flow guide components 300 are set, and in the first state of the flow guide component 300, the inner side surface of the air guide plate 200 and the outer side surface of the air guide plate 200 are provided with protruding flow guide plates, so that the outlet airflow flowing through the inner side surface and the outer side surface of the air guide plate 200 can flow through the part of the air guide plate 200 corresponding to the shielding section 122, the shielding section 122 and flow to the internal component 800. While ensuring the flow rate of the outlet airflow flowing through the part of the air guide plate corresponding to the shielding section 122, the shielding section 122 and flow to the internal component 800, the outlet airflow flows through the inner side surface and the outer side surface of the part of the air guide plate 200 corresponding to the shielding section 122, and the outlet airflow flows through the entire shielding section 122, further improving the effect of limiting the generation of condensation water at the air guide plate 200 and the shielding section 122 and the cleaning effect of the dust at the shielding section 122.

[0078] In this variant embodiment, the accommodating portion 210 comprises a first accommodating groove provided on the inner side of the air deflector 200 and a second accommodating groove provided on the outer side of the air deflector 200. The first guide plate 310 is disposed within the first accommodating groove, and the second guide plate 320 is disposed within the second accommodating groove. Similarly, in the embodiment described above where the accommodating portion 210 is a accommodating hole connecting the inner side of the air deflector 200 and the outer side of the air deflector 200, the beneficial technical effects of the air conditioner indoor unit of this embodiment are also achieved in this variant embodiment and will not be further elaborated here.

[0079] Reference Figure 7 In this embodiment, the sidewalls of the receiving hole or receiving groove are provided with a first limiting protrusion 220 and a second limiting protrusion 230. Furthermore, the first deflector plate 310 is provided with a third limiting protrusion 311, and the second deflector plate 320 is provided with a fourth limiting protrusion 321. In the first state, the third limiting protrusion 311 abuts the first limiting protrusion 220, and the fourth limiting protrusion 321 abuts the second limiting protrusion 230. Consequently, after extending out of the side of the air guide plate 200, the first deflector plate 310 and the second deflector member 300 will not fall out of the receiving hole, ensuring that the deflector member 300 can normally switch between the first and second states.

[0080] Reference Figure 6 or Figure 7 In this embodiment, the driving mechanism 400 includes an electromagnet disposed within the receiving hole and positioned between the first deflector plate 310 and the second deflector plate 320. The electromagnet has a first magnetic pole and a second magnetic pole with opposite magnetic properties. Furthermore, a third magnetic pole is disposed on the end of the first deflector plate 310 corresponding to the first magnetic pole, and a fourth magnetic pole is disposed on the end of the second deflector plate 320 corresponding to the second magnetic pole. The third and fourth magnetic poles have opposite magnetic properties. Furthermore, by energizing the electromagnet, the first and third magnetic poles can be made magnetically identical, and the second and fourth magnetic poles can be made magnetically identical, thereby placing the deflector member 300 in a first state. Furthermore, the electromagnet can be used to place the deflector member 300 in a second state. When there is no need to limit the formation of condensed water on the air guide plate 200, or when the air conditioner is operating in heating mode or other modes, the deflector member 300 does not interfere with the direction and flow rate of the airflow from the air conditioner indoor unit, thereby ensuring normal operation of the air conditioner indoor unit.

[0081] In a modified embodiment, the drive mechanism 400 includes a first electromagnet disposed within the first receiving slot and a second electromagnet disposed within the second receiving slot, with each electromagnet positioned between the bottom of the receiving slot and the drain plate. Furthermore, this modified embodiment does not restrict the relationship between the magnetic poles disposed at the ends of the first drain plate 310 corresponding to the first electromagnet and the magnetic poles disposed at the ends of the second drain plate 320 corresponding to the second electromagnet. Switching between the first and second states of the drain member 300 can be achieved directly by switching the magnetic pole relationship (same or opposite) between the first electromagnet and the opposing ends of the first drain plate 310, and by switching the magnetic pole relationship (same or opposite) between the second electromagnet and the opposing ends of the second drain plate 320. Furthermore, the beneficial technical effects achieved by the aforementioned embodiment in which the electromagnets are disposed within the receiving holes can also be achieved by this modified embodiment, and are not further elaborated here.

[0082] In one implementation manner of the electromagnet in this embodiment, the electromagnet is an electromagnet; the electromagnet is configured so that the magnetic properties of the first pole and the third pole are the same and the magnetic properties of the second pole and the fourth pole are the same; the electromagnet is further configured so that the magnetic properties of the first pole and the third pole are opposite and the magnetic properties of the second pole and the fourth pole are opposite; or, the electromagnet is further configured in a power-off state.

[0083] It should be noted that when the electromagnet is an electromagnet, the drainage component 300 can be switched between the first state and the second state by changing the magnetic poles of the switching electromagnet; and the electromagnet can also be de-energized so that the electromagnet loses its repulsive force on the drainage component 300. At this time, since the drainage component 300 is provided with magnetic poles, it has an attractive force on the electromagnet, thereby realizing the switching of the drainage component 300 from the second state to the first state, so that the drainage component 300 is accommodated in the accommodating hole.

[0084] In another embodiment of the electromagnet in this embodiment, the electromagnet is a spiral coil; the falling coil is configured so that the magnetic properties of the first pole and the third pole are the same and the magnetic properties of the second pole and the fourth pole are the same; the electromagnet is also configured so that the magnetic properties of the first pole and the third pole are opposite and the magnetic properties of the second pole and the fourth pole are opposite.

[0085] It should be noted that when the electromagnet is a solenoid coil, the magnetic poles of the electromagnet can be switched by changing the flow direction of the current flowing through the solenoid coil, thereby switching the drainage member 300 between the first state and the second state.

[0086] In this embodiment, the magnetic poles on the first guide plate 310 and the second guide plate 320 can be the poles of permanent magnets set on the first guide plate 310 and the second guide plate 320, or the poles of permanent electromagnets set on the first guide plate 310 and the second guide plate 320.

[0087] Reference Figure 6 or Figure 7 In this embodiment, the total thickness of the first guide plate 310 , the second guide plate 320 and the electromagnet is the same as the thickness of the air guide plate 200 .

[0088] It can be understood that by making the total thickness of the first guide plate 310, the second guide plate 320 and the electromagnet the same as the thickness of the air guide plate 200, when the guide member 300 is in the second state, the inner side surface or the outer side surface of the air guide plate 200 is a smooth surface, and the inner side surface or the outer side surface of the air guide plate 200 will not be concave at the position of the accommodating hole due to the total thickness of the guide member 300 and the electromagnet being less than the thickness of the air guide plate 200, thereby affecting the air guiding effect of the air guide plate 200; nor will the inner side surface or the outer side surface of the air guide plate 200 be convex at the position of the accommodating hole due to the total thickness of the guide member 300 and the electromagnet being greater than the thickness of the air guide plate 200, thereby affecting the air guiding effect of the air guide plate 200. Therefore, the total thickness of the first guide plate 310, the second guide plate 320 and the electromagnet is the same as the thickness of the air guide plate 200, so that when the air conditioner indoor unit does not need to limit the generation of condensation water on the air guide plate 200, or when the air conditioner indoor unit is operating in heating mode or other modes, the guide component 300 will not interfere with the flow direction and flow rate of the air outlet air flow of the air conditioner indoor unit, thereby ensuring the normal operation of the air conditioner indoor unit.

[0089] In a modified embodiment, the combined thickness of the first electromagnet and first deflector plate 310 is equal to the depth of the first receiving groove, and the combined thickness of the second electromagnet and second deflector plate 320 is equal to the depth of the second receiving groove. Similarly, this arrangement ensures that the deflector member 300 does not interfere with the direction and flow rate of the airflow from the air conditioner indoor unit when there is no need to limit the formation of condensation on the air guide plate 200, or when the air conditioner is operating in heating mode or other modes indoors, thereby ensuring normal operation of the air conditioner indoor unit.

[0090] Reference Figure 8 In this embodiment, the air conditioner indoor unit further includes a humidity sensor 700. The humidity sensor 700 is connected to the driving mechanism 400 and is used to obtain the ambient humidity of the indoor space in which the air conditioner indoor unit operates. In addition, the driving mechanism 400 is configured to: when the ambient humidity is greater than or equal to a preset value, drive the air flow guide member 300 to a first state; when the ambient humidity is less than the preset value, drive the air flow guide member 300 to a second state.

[0091] It is understood that the humidity sensor 700 can be electrically connected to the drive mechanism 400 via the controller 900. Furthermore, the operation of the drive mechanism 400 can be controlled by the controller 900. This allows the flow guide member 300 to switch between different states. Furthermore, only when the concentration in the indoor space reaches a preset value will the flow guide member 300 enter the first state, effectively limiting the formation of condensed water on the air guide plate 200 and the shielding section 122. When the concentration in the indoor space is lower than the preset value, condensed water is unlikely to condense on the air guide plate 200 and the shielding section 122, and the flow guide member 300 enters the second state. Consequently, when there is no need to limit the formation of condensed water on the air guide plate 200, or when the air conditioner is operating in heating mode or other modes indoors, the flow guide member 300 will not interfere with the direction and flow rate of the airflow from the air conditioner indoor unit, ensuring the normal operation of the air conditioner indoor unit.

[0092] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
