Description

Technical Field

[0001] The utility model relates to an air-conditioning range hood. Background Art

[0002] Generally, a range hood is fixed on the wall. During the cooking process, the range hood will generate a large amount of heat, which will increase the temperature in the kitchen and reduce the user experience. In order to solve the problem of high temperature in the kitchen, a refrigeration module is integrated on the traditional range hood to form an air-conditioning range hood. The refrigeration module of the air-conditioning range hood reduces the temperature in the kitchen and improves the comfort of users, thereby enhancing the user experience.

[0003] At present, the condensate generated by the refrigeration module of the air-conditioning range hood on the market is usually discharged externally. Specifically, the condensate condensed on the evaporator is collected in a water receiving tray and flows to the outside through a pipeline with a certain slope.

[0004] However, the external discharge of condensate causes long-term erosion of the external wall of the user and the problem of dripping in the external environment. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defects that the external discharge of condensate in the prior art causes long-term erosion of the external wall of the user and dripping in the external environment, and provide an air-conditioning range hood.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] An air-conditioning range hood, which comprises a casing. An air-conditioning component is installed in the casing. The air-conditioning component includes a compressor, a condenser and an evaporator. The compressor, the condenser and the evaporator are connected and communicated through a refrigerant pipeline. The characteristics are as follows:

[0008] The condensate condensed on the evaporator is collected and then transported to the top of the condenser through a water delivery channel for heat exchange and evaporation of the condensate with the condenser;

[0009] The condenser includes multiple rows of heat exchange tube groups and multiple heat exchange fins. The multiple rows of heat exchange tube groups are arranged at intervals in the horizontal direction. Each row of heat exchange tube groups includes multiple heat exchange tubes arranged vertically and connected in sequence; the multiple heat exchange fins are arranged at intervals in the vertical direction. Each heat exchange fin is arranged horizontally;

[0010] Wherein, each heat exchange fin includes multiple sub-fins in the horizontal direction. The multiple sub-fins correspond to the multiple rows of heat exchange tube groups one by one. Each sub-fin is sleeved outside the corresponding row of heat exchange tube groups; and there is a non-zero first distance between two adjacent sub-fins in the horizontal direction.

[0011] In this technical solution, by providing a water delivery channel for delivering the condensed water condensed on the evaporator to the top of the condenser, the condensed water is evaporated through heat exchange with the condenser, so that there is no need to adopt the method of discharging the condensed water externally, avoiding the erosion of the external wall of the user by the condensed water and the risk of dripping in the external environment. Moreover, by being able to utilize the heat exchange evaporation of the condensed water, the condensation effect of the condenser is improved; further, by defining the specific arrangement mode of the multi-row heat exchange tube groups and the multi-piece heat exchange fins of the condenser, and there is a non-zero first spacing in the horizontal direction between two adjacent sub-fins, during the process of the condensed water spreading horizontally and flowing downward along the heat exchange fins, it can effectively prevent the condensed water from flowing between adjacent rows of heat exchange tube groups, so as to realize the spreading area and the length of the movement path of the condensed water on the surface of the condenser, and thus can efficiently realize the evaporation of the condensed water.

[0012] Preferably, the first spacing is 3 mm to 5 mm.

[0013] In this technical solution, by setting the value range of the first spacing, it is prevented that the first spacing is too small to play the role of blocking the flow of the condensed water between adjacent rows of heat exchange tube groups; while if the first spacing is too large, the overall structure of the condenser will be too large, resulting in the overall occupied space of the air-conditioning range hood being too large.

[0014] Preferably, the water delivery channel includes a plurality of sub-water delivery channels, and the plurality of sub-water delivery channels correspond to the multi-row heat exchange tube groups one by one; in the vertical direction, there is a non-zero second spacing between the water outlet of each sub-water delivery channel and the top of the condenser.

[0015] In this technical solution, by providing a plurality of sub-water delivery channels corresponding to the multi-row heat exchange tube groups one by one, the condensed water can be evenly delivered to each row of heat exchange tube groups; by setting a non-zero second spacing between the water outlet of each sub-water delivery channel and the top of the condenser in the vertical direction, the condensed water can smoothly flow from the water outlet of the sub-water delivery channel to the top of the condenser.

[0016] Preferably, the condenser further includes a first side plate and a second side plate. The first side plate is located above the multi-piece heat exchange fins in the vertical direction, and the second side plate is located below the multi-piece heat exchange fins in the vertical direction. Both the first side plate and the second side plate have fixing holes for the multi-group heat exchange tube groups to pass through, and there is a gap between the outer wall of each heat exchange tube and the inner wall of the corresponding fixing hole;

[0017] In the vertical direction, there is the second spacing between the water outlet of each sub-water delivery channel and the upper surface of the first side plate.

[0018] In this technical solution, a specific setting method of the condenser is provided. By setting that there is a second distance between the water outlet of each sub-water delivery channel in the vertical direction and the upper surface of the first side plate, the condensed water can smoothly flow from the water outlet of each sub-water delivery channel to the upper surface of the first side plate of the condenser, and then flow into the position of multiple heat exchange fins through the gap between the outer wall of the heat exchange tube and the inner wall of the corresponding fixing hole.

[0019] Preferably, each of the second distances is 5 mm to 10 mm.

[0020] In this technical solution, by setting the value range of the second distance, it is prevented that the second distance is too small to block the flow of the condensed water; and if the second distance is too large, the condensed water cannot accurately flow to the top of the condenser.

[0021] Preferably, the air-conditioning assembly further includes a cooling fan. The cooling fan is arranged corresponding to the condenser. When the cooling fan works, a cooling air flow is formed. Multiple rows of the heat exchange tube groups are arranged at intervals along the flow direction of the cooling air flow. The inlets of multiple rows of the heat exchange tube groups are located downstream of the outlets of multiple rows of the heat exchange tube groups along the flow direction of the cooling air flow, and the flow direction forms a non-zero angle with the vertical direction.

[0022] In this technical solution, the cooling fan is provided to achieve the condensation effect of the condenser by means of air cooling; further, by setting that the inlets of multiple rows of the heat exchange tube groups are located downstream of the outlets of multiple rows of the heat exchange tube groups along the flow direction of the cooling air flow, the condenser and the cooling air flow perform countercurrent heat exchange, effectively improving the heat exchange efficiency of the condenser. This is because the temperature of the refrigerant on the side close to the inlets of multiple rows of the heat exchange tube groups is higher than the temperature of the refrigerant on the side close to the outlets of multiple rows of the heat exchange tube groups. After the cooling air flow blows to the side of the outlets of multiple rows of the heat exchange tube groups with a lower temperature for heat exchange, the increase in the temperature of the cooling air flow itself is relatively low. These cooling air flows can still continue to perform heat exchange when they blow to the side of the inlets of multiple rows of the heat exchange tube groups with a higher temperature, so as to effectively improve the heat exchange efficiency of the condenser.

[0023] Preferably, along the flow direction of the cooling air flow, the flow rate in the sub-water delivery channel located downstream is greater than the flow rate in the sub-water delivery channel located upstream.

[0024] In this technical solution, since the sub-water conveyance channels are arranged corresponding to the heat exchange tube groups, the sub-water conveyance channels located downstream are closer to the side of the inlet of the multi-row heat exchange tube groups with higher temperature, while the sub-water conveyance channels located upstream are closer to the side of the outlet of the multi-row heat exchange tube groups with lower temperature. Since the amount of condensed water that can be evaporated on the side closer to the inlet of the multi-row heat exchange tube groups with higher temperature is greater than the amount of condensed water that can be evaporated on the side closer to the outlet of the multi-row heat exchange tube groups with lower temperature, by setting the flow rate in the sub-water conveyance channels located downstream to be greater than the flow rate in the sub-water conveyance channels located upstream, the matching of heat and the amount of sprayed water can be achieved, and the efficient evaporation of condensed water can be realized.

[0025] Preferably, the air-conditioning range hood further includes a range hood component. The range hood fan of the range hood component is located inside the housing, and the outlet of the heat dissipation fan is communicated with the inner cavity of the volute of the range hood fan.

[0026] In this technical solution, by setting the outlet of the heat dissipation fan to be communicated with the inner cavity of the volute of the range hood fan, the air passing through the condenser can be discharged to the common flue through the range hood volute and the flue pipe, without the need to separately set up a discharge pipeline, thus achieving the beneficial technical effect of simplifying the structure.

[0027] Preferably, the condenser includes a first welding part connecting the inlets of the multi-row heat exchange tube groups and the water inlet joint, and a second welding part connecting the outlets of the multi-row heat exchange tube groups and the water outlet joint. The first welding part and the second welding part are both located at the top of the condenser, and the plane where the bottom surfaces of the first welding part and the second welding part are located is higher than the plane where the water outlet of each sub-water conveyance channel is located in the vertical direction.

[0028] In this technical solution, by setting the first welding part and the second welding part to be both located at the top of the condenser, and the plane where the bottom surfaces of the first welding part and the second welding part are located is higher than the plane where the water outlet of each sub-water conveyance channel is located in the vertical direction, the first welding part and the second welding part can be prevented from being corroded by condensed water too quickly.

[0029] Preferably, the air-conditioning range hood further includes a water storage box and a water pump installed in the water storage box. The water conveyance channel communicates the water storage box with the top of the condenser, and the water pump is located at the end of the water conveyance channel close to the water storage box; the water storage box is used for collecting the condensed water condensed on the surface of the evaporator; the water pump is used for pumping the condensed water in the water storage box to the top of the condenser through the water conveyance channel.

[0030] In this technical solution, by setting a water storage box to collect the condensed water condensed on the surface of the evaporator; by setting a water pump to pump the condensed water in the water storage box to the top of the condenser through the water conveyance channel.

[0031] The positive and progressive effects of the present utility model are as follows:

[0032] By providing a water conveyance channel for delivering the condensed water condensed on the evaporator to the top of the condenser, the present utility model enables the condensed water to be evaporated through heat exchange with the condenser, thus eliminating the need for external drainage of the condensed water, avoiding the erosion of the external wall of the user by the condensed water and the risk of dripping in the external environment. Moreover, by utilizing the heat exchange and evaporation of the condensed water, the condensation effect of the condenser is enhanced. Further, by defining the specific arrangement of the multi-row heat exchange tube groups and multi-piece heat exchange fins of the condenser, and having a non-zero first spacing in the horizontal direction between two adjacent sub-fins, during the process of the condensed water spreading horizontally and flowing downward along the heat exchange fins, it is possible to effectively prevent the condensed water from flowing between adjacent rows of heat exchange tube groups, thereby realizing the spreading area and the length of the movement path of the condensed water on the surface of the condenser, and thus enabling efficient evaporation of the condensed water.

In the description of the present utility model, "plural" means two or more, unless otherwise specifically defined.

[0076] As Figures 1 to 6 shown, this embodiment provides an air-conditioning range hood 1. The air-conditioning range hood 1 includes a range hood component 10 and an air-conditioning component 20. Among them, the range hood component 10 is used to achieve the function of sucking oil fumes; the air-conditioning component 20 is used to achieve the air-conditioning function.

[0077] The air-conditioning range hood 1 further includes a housing 30, and the air-conditioning component 20 is installed inside the housing 30. It should be noted that, in order to better display the structure of the components inside the housing 30, Figure 1 what is shown in

[0078] is the structure inside the housing 30.

[0079] The condensed water condensed on the evaporator 23 is collected and then conveyed to the top of the condenser 22 through the water conveyance channel 41 for heat exchange evaporation of the condensed water with the condenser 22. Thus, by providing the water conveyance channel 41 for conveying the condensed water condensed on the evaporator 23 to the top of the condenser 22, the condensed water is evaporated through heat exchange with the condenser 22, so that the method of discharging the condensed water externally is not required, avoiding the erosion of the external wall of the user by the condensed water and the risk of dripping in the external environment. Moreover, by being able to utilize the heat exchange evaporation of the condensed water, the condensation effect of the condenser 22 is improved.

[0080] Furthermore, the condenser 22 includes multiple rows of heat exchange tube groups 221 and multiple heat exchange fins 222. The multiple rows of heat exchange tube groups 221 are arranged at intervals along the horizontal direction O. Each row of heat exchange tube groups 221 includes multiple heat exchange tubes 2211 arranged along the vertical direction H and connected in sequence; the multiple heat exchange fins 222 are arranged at intervals along the vertical direction H, and each heat exchange fin 222 is arranged along the horizontal direction O; wherein, each heat exchange fin 222 includes multiple sub-fins 2221 along the horizontal direction O, and the multiple sub-fins 2221 correspond to the multiple rows of heat exchange tube groups 221 one by one, and each sub-fin 2221 is sleeved outside the corresponding row of heat exchange tube groups 221; and there is a non-zero first spacing D1 between two adjacent sub-fins 2221 along the horizontal direction O. Thus, by defining the specific arrangement mode of the multiple rows of heat exchange tube groups 221 and the multiple heat exchange fins 222 of the condenser 22, and there being a non-zero first spacing D1 between two adjacent sub-fins 2221 along the horizontal direction O, during the process of the condensed water spreading and flowing downward along the heat exchange fin 222 in the horizontal direction O, it can effectively prevent the condensed water from flowing between adjacent rows of heat exchange tube groups 221, thereby realizing the spreading area and the length of the movement path of the condensed water on the surface of the condenser 22, and thus being able to efficiently realize the evaporation of the condensed water.

[0081] In this embodiment, the condenser 22 includes three rows of heat exchange tube groups 221. Correspondingly, each heat exchange fin 222 includes three sub-fins 2221, and the sub-fins 2221 correspond to the rows of heat exchange tube groups 221 one by one. However, it is not limited thereto. The number of heat exchange tube groups 221 included in the condenser 22 can also be two, four, five or other values. Correspondingly, the number of sub-fins 2221 can also be two, four, five or other values.

[0082] Preferably, the first spacing D1 is 3 mm to 5 mm. Thus, by setting the value range of the first spacing D1, it is prevented that the first spacing D1 is too small to play a role in blocking the flow of the condensed water between adjacent rows of heat exchange tube groups 221; and if the first spacing D1 is too large, the overall structure of the condenser 22 becomes too large, resulting in the overall occupied space of the air-conditioning range hood 1 being too large.

[0083] The water delivery channel 41 includes a plurality of sub - water delivery channels 411, and the plurality of sub - water delivery channels 411 correspond to the plurality of rows of heat exchange tube groups 221 one by one; along the vertical direction, there is a non - zero second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the top of the condenser 22. In this way, by setting a plurality of sub - water delivery channels 411 corresponding to the plurality of rows of heat exchange tube groups 221 one by one, condensed water can be evenly delivered to each row of heat exchange tube groups 221; by setting a non - zero second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the top of the condenser 22 along the vertical direction H, the condensed water can smoothly flow from the water outlet 4111 of the sub - water delivery channel 411 to the top of the condenser 22. In this embodiment, since the sub - water delivery channels 411 correspond to the heat exchange tube groups 221 one by one, the number of sub - water delivery channels 411 is also three. However, this is not limited to this, and the number of sub - water delivery channels 411 corresponds to the number of heat exchange tube groups 221, and can also be two, four, five or other values.

[0084] Specifically, the condenser 22 further includes a first side plate 223 and a second side plate 224. The first side plate 223 is located above the plurality of heat exchange fins 222 along the vertical direction H, and the second side plate 224 is located below the plurality of heat exchange fins 222 along the vertical direction H. Both the first side plate 223 and the second side plate 224 have fixing holes for the plurality of heat exchange tube groups 221 to pass through, and there is a gap between the outer wall of each heat exchange tube 2211 and the inner wall of the corresponding fixing hole. In this way, a specific setting manner of the condenser 22 is provided, and by setting a second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the upper surface of the first side plate 223 along the vertical direction H, the condensed water can smoothly flow from the water outlet 4111 of each sub - water delivery channel 411 to the upper surface of the first side plate 223 of the condenser 22, and then flow into the position of the plurality of heat exchange fins 222 through the gap between the outer wall of the heat exchange tube 2211 and the inner wall of the corresponding fixing hole.

[0085] There is a second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the upper surface of the first side plate 223 along the vertical direction H. Preferably, each second spacing D2 is 5 mm to 10 mm. In this way, by setting the value range of the second spacing D2, it is prevented that the second spacing D2 is too small to block the flow of condensed water; and if the second spacing D2 is too large, the condensed water cannot accurately flow to the top of the condenser 22. In this embodiment, the second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the upper surface of the first side plate 223 is the same. However, this is not limited to this. In other embodiments, the second spacing D2 between the water outlet 4111 of each sub - water delivery channel 411 and the upper surface of the first side plate 223 may not be the same; or, the second spacings D2 of some quantities are the same and the second spacings D2 of the remaining quantities are different, which can be adjusted according to design requirements.

[0086] In this embodiment, the air-conditioning assembly 20 further includes a cooling fan 24, which is arranged corresponding to the condenser 22. When the cooling fan 24 operates, a cooling air flow is formed. The three rows of heat exchange tube groups 221 are arranged at intervals along the flowing direction F of the cooling air flow. The inlet 2212 of the three rows of heat exchange tube groups 221 is located downstream of the outlet 2213 of the three rows of heat exchange tube groups 221 along the flowing direction F of the cooling air flow, and the flowing direction F forms a non-zero angle with the vertical direction H. The flowing direction F forms a non-zero angle with the vertical direction H, that is to say, the cooling air flow blows into the condenser 22 from one side of the condenser 22, rather than from the top or bottom of the condenser 22.

[0087] In this way, by setting the cooling fan 24, the condensation function of the condenser 22 is realized by air cooling; further, by setting the inlet 2212 of the three rows of heat exchange tube groups 221 to be located downstream of the outlet 2213 of the three rows of heat exchange tube groups 221 along the flowing direction F of the cooling air flow, the condenser 22 and the flowing direction F of the cooling air form countercurrent heat exchange, effectively improving the heat exchange efficiency of the condenser 22. This is because the temperature of the refrigerant on the side close to the inlet 2212 of the three rows of heat exchange tube groups 221 is higher than the temperature of the refrigerant on the side close to the outlet 2213 of the three rows of heat exchange tube groups 221. After the cooling air flow blows to the side of the outlet 2213 of the three rows of heat exchange tube groups 221 with a lower temperature for heat exchange, the increase in the temperature of the cooling air flow itself is relatively low. These cooling air flows can still continue to exchange heat when they blow to the side of the inlet 2212 of the three rows of heat exchange tube groups 221 with a higher temperature, thereby effectively improving the heat exchange efficiency of the condenser 22.

[0088] Preferably, along the flowing direction F of the cooling air flow, the flow rate in the downstream sub-water conveyance channel 411 is greater than the flow rate in the upstream sub-water conveyance channel 411. Since the sub-water conveyance channel 411 is arranged corresponding to the heat exchange tube group 221, the downstream sub-water conveyance channel 411 is closer to the side of the inlet 2212 of the three rows of heat exchange tube groups 221 with a higher temperature, and the upstream sub-water conveyance channel 411 is closer to the side of the outlet 2213 of the three rows of heat exchange tube groups 221 with a lower temperature. Since the amount of condensed water that can be evaporated on the side close to the inlet 2212 of the three rows of heat exchange tube groups 221 with a higher temperature is greater than the amount of condensed water that can be evaporated on the side close to the outlet 2213 of the three rows of heat exchange tube groups 221 with a lower temperature, by setting the flow rate in the downstream sub-water conveyance channel 411 to be greater than the flow rate in the upstream sub-water conveyance channel 411, the matching of heat and the amount of water sprayed can be achieved, and the efficient evaporation of condensed water can be realized.

[0089] Preferably, the condenser 22 includes a first welding portion connecting the inlet 2212 of the three-row heat exchange tube group 221 to the water inlet joint, and a second welding portion connecting the outlet 2213 of the three-row heat exchange tube group 221 to the water outlet joint. Both the first welding portion and the second welding portion are located at the top of the condenser 22, and the plane where the bottom surfaces of the first welding portion and the second welding portion are located is higher than the plane where the water outlet 4111 of each sub-water delivery channel 411 is located in the vertical direction H. In this way, by setting both the first welding portion and the second welding portion at the top of the condenser 22, and the plane where the bottom surfaces of the first welding portion and the second welding portion are located is higher than the plane where the water outlet 4111 of each sub-water delivery channel 411 is located in the vertical direction H, it is possible to prevent the first welding portion and the second welding portion from being corroded by the condensed water too quickly.

[0090] In this embodiment, the heat exchange tube 2211 is a U-shaped tube, and adjacent heat exchange tubes 2211 are connected by a U-shaped joint 226, and the U-shaped joint 226 is located above the first side plate 223.

[0091] The range hood assembly 10 includes a range hood fan 11. The range hood fan 11 is located inside the housing 30, and the outlet 2213 of the heat dissipation fan 24 is communicated with the inner cavity of the volute of the range hood fan 11. In this way, by setting the outlet 2213 of the heat dissipation fan 24 to be communicated with the inner cavity of the volute of the range hood fan 11, the air passing through the condenser 22 can be discharged to the common flue through the range hood volute and the flue pipe, without the need to separately arrange a discharge pipeline, thereby achieving the beneficial technical effect of simplifying the structure.

[0092] The range hood assembly 10 further includes a smoke hood 12. The smoke hood 12 is located below the housing 30, and the smoke hood 12 is provided with an air inlet cavity communicated with the range hood fan 11, and an air inlet is opened on the side of the air inlet cavity away from the housing 30.

[0093] The air conditioner assembly 20 further includes an indoor fan 25. The indoor fan 25 is arranged corresponding to the evaporator 23, and the indoor fan 25 is used to blow out the air heat-exchanged with the evaporator 23 from the housing 30 of the air conditioner range hood 1. At one end of the smoke hood 12 close to the housing 30, an air conditioner air outlet 26 communicated with the indoor fan 25 is opened on the side facing the user.

[0094] The air conditioner range hood 1 further includes a water storage box 42 and a water pump 43 installed in the water storage box 42. The water delivery channel 41 communicates the water storage box 42 with the top of the condenser 22, and the water pump 43 is located at the end of the water delivery channel 41 close to the water storage box 42; the water storage box 42 is used to collect the condensed water condensed on the surface of the evaporator 23; the water pump 43 is used to pump the condensed water in the water storage box 42 to the top of the condenser 22 through the water delivery channel 41. In this way, by setting the water storage box 42 to collect the condensed water condensed on the surface of the evaporator 23; by setting the water pump 43 to pump the condensed water in the water storage box 42 to the top of the condenser 22 through the water delivery channel 41.

[0095] The water delivery channel 41 further includes a water distributor 413. One end of each sub-water delivery channel 411 away from the condenser 22 is communicated with one side of the water distributor 413, and the other side of the water distributor 413 is communicated with the water storage box 42.

[0096] The condenser 22 is located inside the housing of the cooling fan 24. The air-conditioning range hood 1 further includes a water return channel 44. The water return channel 44 communicates the bottom of the housing and the water storage box 42, and the unevaporated condensed water is collected at the bottom of the housing. In this way, by providing the water return channel 44 that communicates the bottom of the housing and the water storage box 42, the unevaporated condensed water can be recovered to the water storage box 42, which is convenient for later conveying the condensed water to the top of the condenser 22 for the next round of heat exchange evaporation.

[0097] In this embodiment, by providing the water delivery channel 41 that conveys the condensed water condensed on the evaporator 23 to the top of the condenser 22, the condensed water is heat-exchanged and evaporated with the condenser 22, so that there is no need to adopt the method of discharging the condensed water externally, avoiding the erosion of the external wall of the user by the condensed water and the risk of dripping in the external environment. Moreover, by being able to utilize the heat-exchange evaporation of the condensed water, the condensation effect of the condenser 22 is improved; further, by defining the specific setting method of the multi-row heat exchange tube group 221 and the multi-piece heat exchange fins 222 of the condenser 22, and there is a non-zero first spacing D1 in the horizontal direction O between two adjacent sub-fins 2221, during the process of the condensed water spreading in the horizontal direction O and flowing downward along the heat exchange fins 222, it can effectively prevent the condensed water from flowing between adjacent rows of the heat exchange tube group 221, so as to realize the spreading area and the length of the movement path of the condensed water on the surface of the condenser 22, and thus can efficiently realize the evaporation of the condensed water.

[0098] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
