Description

TECHNICAL FIELD

[0001] The present application belongs to the mechanical technical field, and relates to an air conditioning device. BACKGROUND

[0002] In daily life, the air in the room is often dry, especially in summer and winter, due to the temperature difference between inside and outside, the room is often in a closed state, the air circulation is not timely, the indoor air will be more dry. Dry indoor air is harmful to human health, not only can cause a large amount of water loss in the human body, causing symptoms such as internal heat, skin tightness, dry mouth and throat, cracked lips, but also can cause respiratory diseases such as influenza and pharyngitis. Therefore, a humidifier is often used in daily life to increase the humidity of the room.

[0003] The existing humidifier, such as Chinese patent application (application number: 200920023628.8) discloses a humidifier, which comprises a motor, a fan, a support and a water storage tank. The water storage tank is arranged at the bottom and serves as a base. The water storage tank is open upward. The support is arranged on the water storage tank. An air inlet is arranged on the side of the support. A humidifying air duct is formed in the support from the air inlet to an air outlet of the fan. A pump wheel of a water pump is coaxially arranged on the rotor of the motor. The pump wheel extends downward into the pump body of the water pump. The pump body is a sleeve which is arranged outside the pump wheel and is supported and fixed by the support. An annular water spraying opening is formed at the top of the sleeve of the pump body. The pump body extends downward into the water storage tank. The motor is fixed on the top of the support. When working, the motor drives the fan and the pump wheel to rotate simultaneously. The water in the water storage tank flows to the side wall of the pump body under the action of centrifugal force, rises along the side wall to the annular water spraying opening, and is sprayed from the annular water spraying opening to form a fountain. The water is sprayed to the inner side wall of the support to shield the air inlet. After the water collides with the inner side wall of the support, part of the water splashes on the inner side wall of the support to form water mist. The air entering through the air inlet flows upward directly, carries the water mist formed above, and then flows into the fan to discharge the humidified air from the air outlet.

[0004] The above-mentioned humidifier is similar to the ordinary humidifier. The discharged air is in the form of water mist, which can well increase the indoor humidity. However, in summer, the indoor air is not only dry but also has a high temperature. If a person stays in the high temperature environment for a long time, the heat homeostasis of the human body will be disturbed, the human body cannot dissipate heat in time, and the person is prone to heat stroke or other diseases. Therefore, only indoor humidification cannot meet the demand, and the person also needs to be cooled by blowing air. Although the above-mentioned humidifier is provided with a fan, the design of the fan is only to carry out the water mist formed by the fountain from the air outlet to spray the water mist for humidification. Therefore, the air volume of the fan is generally small, and the fan only plays a role in air circulation and does not have the function of blowing and cooling. The function of the humidifier is single. Obviously, the above-mentioned humidifier cannot meet the demand of people in summer. Moreover, in the process of spraying the water from the pump body to form a fountain, the sprayed water is easy to splash out of the air inlet on the support.

[0005] If the fan in the humidifier is set as a large-power fan with the function of blowing, a large amount of water mist will be blown out at the same time of blowing cool wind, and generally, the fan is blown to the human body in order to blow wind and cool, that is, a large amount of water mist is blown to the human body at the same time of blowing wind. The humidity of air is not higher and higher, and the humidity that the human body feels more comfortable has a tolerance limit. If the humidity of air is too high, the human body will feel chest tightness and breathing difficulty. Obviously, the above setting has exceeded the tolerance limit of the human body to humidity, so the conventional technical personnel in the field will not do so, that is, in the conventional cognition of the technical personnel in the field, the fan in the humidifier is mainly to spray water mist, and the main function is to increase the humidity of the environment.

[0006] In order to meet the simultaneous needs of people for humidification and blowing wind and cooling, the conventional methods in the field are as follows: 1, setting a humidifier and an electric fan capable of blowing wind in the room, and the two devices are used together, but the two devices occupy a large space, and two driving sources are needed to connect the power supply, the energy consumption is large, and at the same time, since the environmental temperature is high, the wind blown by the electric fan is also hot, and the cooling effect is not good. 2, the electric fan and the humidifier are made into an integrated structure, such as the electric fan humidifier disclosed in Chinese patent application (application number: 201520398455.3) and the electric fan humidifier disclosed in Chinese patent application (application number: 201220079704.9). Although the electric fan and the humidifier are made into an integrated structure, the space occupied is reduced, but the electric fan and the humidifier are still two independent functional components in essence, and work separately, and the power energy required by the two is also independent of each other, which is basically the same as the split type electric fan and the humidifier, and the energy consumption is still large. SUMMARY

[0007] The purpose of the present application is to solve the above problems existing in the prior art, and the technical problem to be solved by the present application is that the existing humidifier cannot meet the simultaneous needs of people for humidification and cooling at the same time of ensuring the comfortable tolerance humidity of the human body.

[0008] The air conditioning device comprises a shell with an air inlet and an air outlet, a motor and a water pumping body arranged in the shell, a fan connected to a rotating shaft of the motor, a water storage cavity in the bottom of the shell, and a water throwing part on the water pumping body.

[0009] The water storage cavity of the air conditioning device can be used to store water and liquid such as aromatherapy. The water pumping body extends into the water storage cavity. When the motor operates, the water pumping body rotates to pump the liquid in the water storage cavity into the water pumping body and out through the water throwing part. Since the water throwing part is located above the air inlet and below the air outlet, the liquid is thrown onto the inner wall of the shell. Part of the liquid flows downward along the inner wall of the shell, and the other part of the liquid forms a large amount of water mist at the inner wall of the shell due to collision. Since the baffle is arranged on the inner wall of the shell and located between the air inlet and the water throwing part, most of the water mist formed by collision is blocked by the baffle to form water droplets, which converge with the other part of the liquid flowing downward along the inner wall of the shell. The converged liquid flows downward along the inner circle of the baffle back to the water storage cavity, thereby forming a water curtain in the shell. At the same time, the motor drives the fan to rotate, and air enters the shell from the air inlet. Due to the presence of the baffle, the air entering from the air inlet is blocked by the baffle and does not flow directly upward, but flows in the direction of the water curtain and passes through the water curtain. The air can exchange heat with the water curtain and carry most of the heat, and the dust in the air is also removed by the water curtain, thereby achieving air purification and cooling. After passing through the water curtain, the air also carries some humidity, and then flows upward along the inner circle of the baffle. Since there is relatively little water mist in the inner circle of the baffle, the air passing through the inner circle of the baffle will only carry a small amount of water mist above the inner circle of the baffle, and then pass through the water curtain thrown by the water throwing part for secondary cooling and purification, thereby discharging cool, pure, and humid air from the air outlet. That is, the air conditioning device changes the flow path of the air entering from the air inlet by designing the baffle, so that the air avoids the water mist concentration area near the inner wall of the shell. The air curtain is composed of the water curtain, the baffle, the water pumping body, and the shell. The air passing through the air curtain can fully exchange temperature and humidity with the liquid, and purify the air. The device can provide air cooling while ensuring appropriate humidity without exceeding the human tolerance limit. The device integrates humidification, cooling, air purification, and other functions, and achieves the above functions by using one fan and one motor, which has relatively low energy consumption.

[0010] In the air conditioning device, the inner edge of the baffle extends downward to form a guide plate in a cylindrical shape. The guide plate can guide the flow of the liquid after converging at the baffle, so that the liquid can flow downward along the plate surface of the guide plate. The guide plate can further isolate a small part of the water mist falling below the baffle to converge with the water flow along the guide plate, so as to better form a water curtain at the air inlet. The air entering from the air inlet first passes through the water curtain and then flows upward from the inner ring of the baffle. To some extent, the moisture in the air discharged from the air outlet is reduced, and cool, pure and humid air is discharged from the air outlet. The simultaneous needs of humidification and air blowing for cooling are met while ensuring the comfortable tolerance humidity of the human body.

[0011] In the air conditioning device, the connection between the guide plate and the baffle is connected in a circular arc transition. The circular arc transition makes the liquid flow more smoothly along the baffle and the guide plate, and the formed water curtain is more complete. The air entering from the air inlet can better pass through the water curtain and then be discharged from the air outlet. The discharged air is relatively cool, pure and humid. The simultaneous needs of humidification and air blowing for cooling are met while ensuring the comfortable tolerance humidity of the human body.

[0012] In the air conditioning device, the inner wall of the shell further has a guide surface, the inner diameter of the guide surface gradually decreases from the bottom to the top of the shell, and the guide surface is located between the air outlet and the baffle. During the process of air flowing through the water curtain to the air outlet, the air has a converging and pressurizing effect along the guide surface when passing through the guide surface, increasing the air speed and making the air blowing effect better. The guide surface can also block part of the water mist in the air to some extent, further meeting the simultaneous needs of humidification and air blowing for cooling while ensuring the comfortable tolerance humidity of the human body.

[0013] In the air conditioning device, the shell further has a ring-shaped reinforcing member, and the reinforcing member has a plurality of air passages. The design of the ring-shaped reinforcing member ensures the strength of the shell as a whole. The design of the plurality of air passages on the reinforcing member ensures that the air entering from the air inlet can flow to the air outlet after passing through the water curtain. The air can be divided into multiple streams during the flow process, and part of the water mist and dust in the air can be blocked to some extent. The simultaneous needs of humidification and air blowing for cooling are met while ensuring the comfortable tolerance humidity of the human body.

[0014] In the air conditioning device, the reinforcing member is further provided with a filter member through which air passes. The filter member is designed to prevent liquid in the pump water body from splashing upward, to block and absorb the liquid, to prevent the liquid from entering the motor and the fan, and to form a water film at the filter member, so that the excess liquid after absorption can fall back to the water storage cavity under the action of gravity, thereby further filtering and purifying the air passing through the water curtain and performing heat exchange and cooling, which is equivalent to three times of cooling and purification of the air entering from the air inlet through the water curtain, the water curtain of the water throwing part, and the filter member, so that cool, pure, and humid air is discharged from the air outlet, ensuring the comfortable tolerance humidity of the human body and meeting the simultaneous needs of humidification and air blowing.

[0015] In the air conditioning device, the housing is cylindrical, a plurality of air inlets are formed in the outer wall of the housing in the circumferential direction, the air inlets are long strips extending in the axial direction of the housing, and the axial length of the flow guide plate is less than the length of the air inlets. The flow guide plate partially blocks the air inlets, part of the air entering the air inlets can pass through the water curtain below the flow guide plate, and the other part is blocked by the flow guide plate, thereby forming an air convection upward and downward, increasing the air flow at the air inlets, and the flow guide plate can also block the air inlets with the water curtain, ensuring that the air entering the air inlets can pass through the water curtain, and cool, pure, and humid air is discharged from the air outlet, ensuring the comfortable tolerance humidity of the human body and meeting the simultaneous needs of humidification and air blowing.

[0016] In the air conditioning device, the pump water body is cylindrical and penetrates through both ends, the inner diameter of the pump water body gradually increases from the bottom to the top of the housing, and the water throwing part is an annular protruding rib arranged on the outer peripheral wall of the top end of the pump water body. The rotation of the pump water body driven by the motor can generate a vortex in the water storage cavity, and the pump water body as a whole is a conical cylinder, which is adapted to the shape of the vortex. Under the action of the vortex, the water in the water storage cavity can flow upward along the inner wall of the pump water body and overflow from the upper port of the pump water body, and then be thrown in the circumferential direction along the annular protruding rib on the outer peripheral wall of the pump water body to the inner wall of the housing. Compared with the pump water mode of the impeller, the energy consumption is smaller.

[0017] In the air conditioning device, the pump water body is cylindrical, and the inner diameter of the pump water body gradually increases from the bottom to the top of the housing, and the water throwing part is a water spraying port formed in the side wall of the pump water body. The rotation of the pump water body driven by the motor can generate a vortex in the water storage cavity, and the pump water body as a whole is a conical cylinder, which is adapted to the shape of the vortex. Under the action of the vortex, the water in the water storage cavity can flow upward along the inner wall of the pump water body and be thrown in the circumferential direction from the water spraying port to the inner wall of the housing. Compared with the pump water mode of the impeller, the energy consumption is smaller.

[0018] As preferred, in the air conditioning device, the water spraying ports are arranged in groups and evenly distributed along the circumference of the water pumping body. As further preferred, the water spraying ports are provided with electromagnetic valves capable of adjusting the sizes of the water spraying ports. Through the design of the electromagnetic valves, the sizes of the water spraying ports can be adjusted, so that the water column or water mist sprayed from the water spraying ports can be adjusted according to the requirements, so that the air conditioning device can also spray water mist alone as a humidifier when not used as an electric fan, so that the range of use is wider and can be adjusted according to the different requirements of the users.

[0019] In the air conditioning device, the shell includes a bottom shell, a lower shell, an upper shell and a top cover which are all cylindrical and connected in sequence, the motor and the fan are arranged in the top cover, the side wall of the top cover is provided with the air outlet, the flow guide surface is arranged on the inner wall of the upper shell, a plurality of air inlets are arranged on the outer circumferential wall of the lower shell, the flow baffle is arranged on the inner wall of the lower shell and integrally formed with the lower shell, the inner cavity of the bottom shell is the water storage cavity, and the two ends of the water pumping body are respectively arranged in the upper shell and the bottom shell. Through the above arrangement, the components are designed in a split manner, which is convenient for mold opening, manufacturing, and subsequent disassembly, cleaning and maintenance.

[0020] As preferred, in the air conditioning device, the bottom shell, the lower shell, the upper shell and the top cover are all made of transparent materials. By using transparent materials, the water curtain inside the device can be observed from the outside during use, so that the device also has a decorative function.

[0021] In the air conditioning device, the bottom end of the water pumping body is provided with a connecting shaft portion, a plurality of connecting ribs are radially arranged on the connecting shaft portion, the connecting shaft portion is fixed to the inner wall of the bottom end of the water pumping body through the connecting ribs, and the connecting shaft portion is rotatably connected to the bottom shell. The bottom of the water pumping body is rotatably connected to the bottom shell, so that the operation is stable and does not shake, and the structural strength is higher with the connecting ribs. During rotation, it is easier to generate vortex in water and to spray water from the water spraying part.

[0022] Compared with the prior art, the air conditioning device has the following advantages:

[0023] 1. By the design of the baffle and the deflector, the flow path of the air after entering from the air inlet is changed, so that it avoids the water mist concentration area near the inner wall of the shell, to a certain extent, reduces the moisture in the air discharged from the air outlet, and at the same time, the water mist near the inner wall of the shell and the water flow along the inner wall of the shell are collected to form a water curtain, so that the discharged air is relatively cool, pure and humid, which meets the synchronous needs of people for humidification and air cooling while ensuring the comfortable tolerance humidity of human body.

[0027] 5. The shell is designed in a split type, which is convenient for opening mold, easy to manufacture, and convenient for disassembly, cleaning and maintenance in the subsequent use process.

[0028] 6. The shell is made of transparent material, so that the water curtain inside the device can be seen from the outside during use, and the device also has a decoration function. BRIEF DESCRIPTION OF DRAWINGS

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] Example 1

[0040] like Figures 1-3 As shown, this air conditioning device includes a housing 1, a motor 2, and a water pump 3. The housing 1 includes a bottom shell 1a, a lower shell 1b, an upper shell 1c, and a top cover 1d, all cylindrical and connected in sequence. The bottom shell 1a, lower shell 1b, upper shell 1c, and top cover 1d are all made of transparent material. The motor 2 and the fan 4 are both located inside the top cover 1d. The motor 2 is fixed to the top cover 1d, and the fan 4 is fixed to the shaft of the motor 2, and the motor 2 can drive the fan 4 to rotate. An air outlet 1d1 is provided on the side wall of the top cover 1d, and the air outlet 1d1 is opposite to the fan 4. In this embodiment, the inner wall of the air outlet 1d1 protrudes along the circumferential tangent direction of the top cover 1d and is parallel to the side of the top cover 1d. The fan 4 is an axial flow fan.

[0041] Specifically, such as Figure 3 and 6As shown, the inner cavity of the bottom shell 1a forms a water storage cavity 1a1, which can be used to hold water, liquid fragrance, etc. The outer side wall of the lower shell 1b is provided with a plurality of air inlets 1b1 in the circumferential direction, which are long strips and extend along the axial direction of the lower shell 1b. The pump water body 3 is cylindrical, and the inner diameter of the pump water body 3 gradually increases from the bottom to the top of the shell 1, and the top end of the pump water body 3 is located in the lower shell 1b. The pump water body 3 has a connecting sleeve 3d near the top end, and a plurality of connecting plates 3e are radially arranged on the outer peripheral wall of the connecting sleeve 3d, and the connecting sleeve 3d and the inner wall of the pump water body 3 are connected by the connecting plates 3e. The shaft of the motor 2 extends into the lower shell 1b and penetrates into the connecting sleeve 3d, and the side wall of the connecting sleeve 3d is provided with a threaded hole, and the threaded hole is tightly connected to the shaft of the motor 2 by a bolt, so that the shaft of the motor 2 is fixed to the pump water body 3. The bottom end of the pump water body 3 extends into the water storage cavity 1a1, and the bottom end of the pump water body 3 has a connecting shaft part 3b, a plurality of connecting ribs 3c are radially arranged on the connecting shaft part 3b, and the connecting shaft part 3b is fixed to the inner wall of the bottom end of the pump water body 3 by the connecting ribs 3c. The bottom of the bottom shell 1a has a connecting groove, and the connecting shaft part 3b is rotatably connected in the connecting groove. The bottom end of the pump water body 3 is also provided with a filtering device capable of filtering and purifying the liquid entering the pump water body 3. In this embodiment, the connecting shaft part 3b and the groove wall of the connecting groove are made of ceramic material, and the filtering device is an activated carbon filter screen.

[0042] Further, as shown in Figure 3 and 5 , the top end of the pump water body 3 has a water throwing part 3a, which is located above the air inlet 1b1 and below the air outlet 1d1. The motor 2 can drive the pump water body 3 to rotate to pump the liquid in the water storage cavity 1a1 into the pump water body 3 and throw it along the circumferential direction of the pump water body 3 through the water throwing part 3a. The lower shell 1b is also provided with a baffle 5, which is annular and protrudes from the inner wall of the lower shell 1b along the circumferential direction of the lower shell 1b. The baffle 5 is located above the air inlet 1b1 and below the water throwing part 3a. The inner edge of the baffle 5 extends downward to form a cylindrical flow guide plate 5a, and the connection between the baffle 5 and the flow guide plate 5a is connected in a circular arc. The axial length of the flow guide plate 5a is less than the length of the air inlet 1b1, that is, the flow guide plate 5a partially blocks the air inlet 1b1. In this embodiment, the baffle 5, the flow guide plate 5a and the lower shell 1b are integrally formed, the water throwing part 3a is a water outlet formed on the side wall of the pump water body 3, the water outlet has a plurality of groups and is uniformly distributed along the circumferential direction of the pump water body 3, and the water outlet is provided with an electromagnetic valve capable of adjusting the size of the water outlet.

[0043] Further, as shown in Figure 3 and 4As shown, the inner wall of the upper shell 1c further has a flow guide surface 1c1, the inner diameter of the flow guide surface 1c1 gradually decreases from the bottom to the top of the shell 1, and the flow guide surface 1c1 is located between the air outlet 1d1 and the baffle 5. The shell 1 further has a ring-shaped reinforcing member 6, which provides guarantee for the strength of the shell 1 as a whole, and the reinforcing member 6 has a plurality of air passing openings 6a. The reinforcing member 6 further has a filter 7 through which air can pass, which can prevent the liquid in the water body 3 from splashing upward, block and absorb the liquid, avoid the liquid from entering the motor 2 and the fan 4, and form a layer of water film at the filter 7, so that the excess liquid after absorption can fall back to the water storage cavity 1a1 under the action of gravity, thereby further filtering and purifying the air after passing through the water curtain and heat exchanging and cooling, which is equivalent to three times of cooling and purification of the air after entering the air inlet 1b1, i.e. the water curtain, the water curtain of the water throwing part and the filter 7, so that the cool, pure and humid air is discharged from the air outlet 1d1, which guarantees the comfortable tolerance humidity of the human body and meets the synchronous needs of humidification and air blowing cooling. In the embodiment, the reinforcing member 6 includes an inner ring, a middle ring and an outer ring, which are sequentially sleeved from inside to outside and connected to each other by a plurality of radial ribs and form the above-mentioned air passing openings 6a between them. The filter 7 can be a thin sheet-shaped water-absorbing sponge through which air can pass, or an activated carbon filter screen, etc.

[0044] When the air conditioning device works, the motor 2 drives the pump water body 3 to rotate to generate a vortex in the water storage cavity 1a1, and the pump water body 3 as a whole is in the shape of a cone cylinder, which is adapted to the shape of the vortex. Through the action of the vortex, the water in the water storage cavity 1a1 can flow upwards along the inner wall of the pump water body 3 and be thrown from the water outlet to the inner wall of the lower shell 1b in the circumferential direction. Part of the liquid flows downwards along the inner wall of the shell 1, and another part of the liquid collides to form a large amount of water mist at the inner wall of the shell 1. The water mist is blocked by the baffle 5 to form water droplets during the falling process, and the water droplets flow together with another part of the liquid flowing downwards along the inner wall of the shell 1. The guide plate 5a can further isolate a small part of the water mist that falls below the baffle 5, and at the same time, the guide plate 5a can also guide the flow of the liquid after converging at the baffle 5, so that the liquid can flow downwards along the surface of the guide plate 5a, thereby forming a water curtain at the inner periphery of the air inlet 1b1 to block the air inlet 1b1. At the same time, the motor 2 drives the fan 4 to rotate, and air enters the shell 1 from the air inlet 1b1. Due to the existence of the water curtain, the air entering from the air inlet 1b1 first passes through the water curtain, and the air can exchange heat with the water curtain and carry most of the heat, and at the same time, the dust in the air is also taken away by the water curtain, thereby realizing the purification and cooling of the air. After the air passes through the water curtain, the air also carries some humidity, and after cutting through the inner ring of the baffle 5, it also takes away a small part of the water mist floating above the baffle 5, and after being cut by the reinforcing member 6 and concentrated by the guide surface 1c1, the water in the air discharged from the air outlet 1d1 is reduced to a certain extent, so that the fan 4 can directly blow on the human body. Moreover, the air discharged from the air outlet 1d1 is cool, pure and humid, which not only ensures the comfortable tolerance humidity of the human body, but also meets the synchronous demand of people for humidification and air blowing cooling. That is to say, the device can simultaneously have the functions of a humidifier and an electric fan, and through one fan 4 and one motor 2, the functions of air blowing and humidification are simultaneously realized, and the energy consumption is relatively lower.

[0045] At the same time, the shell 1 of the device is transparent, and the water curtain inside can be observed from the outside during use, so that the device also has the function of decoration. In addition, the device can also adjust the water column or water mist thrown from the water outlet according to the needs, so that the air conditioning device can also spray water mist alone as a humidifier when not used as an electric fan, so that the range of use is wider and can be adjusted according to the different needs of the user.

[0046] Example two

[0047] The structure of this embodiment is basically the same as that of example one, and the difference lies in that:

[0048] As Figure 7 and 8As shown, the pump water body 3 penetrates through both ends of the housing 1, the inner diameter of the pump water body 3 gradually increases from the bottom to the top of the housing 1, and the water throwing part 3a is an annular protruding rib arranged on the outer peripheral wall of the top end of the pump water body 3. The rotation of the motor 2 and the pump water body 3 can generate a vortex in the water storage cavity 1a1, and the pump water body 3 as a whole is a conical cylinder which is adapted to the shape of the vortex. Through the action of the vortex, the water in the water storage cavity 1a1 can flow upwards along the inner wall of the pump water body 3 and overflow from the upper end of the pump water body 3, and then be thrown in the circumferential direction along the annular protruding rib on the outer peripheral wall of the pump water body 3 to the inner wall of the housing 1. Compared with the pump water mode of the impeller, the energy consumption is smaller.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0050] Although the terms such as housing 1, bottom shell 1a, water storage cavity 1a1, lower shell 1b, air inlet 1b1, upper shell 1c, flow guide surface 1c1, top cover 1d, air outlet 1d1, motor 2, pump water body 3, water throwing part 3a, connecting shaft part 3b, connecting rib 3c, connecting sleeve 3d, connecting plate 3e, fan 4, baffle 5, flow guide plate 5a, reinforcing member 6, air passage 6a, etc. are used more frequently herein, but the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the present application; any interpretation of them as any kind of additional limitation is contrary to the spirit of the present application.
