Detailed implementation manners

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the attached drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the attached drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0029] Household heat pump equipment integrates a water circuit system and a fluorine circuit system, enabling the heat pump equipment to realize the functions of making hot water and cold water to meet different customer needs. For example, the heat pump equipment is a sky-water and ground-water system. Through the heat exchange between freon and water, cold water or hot water is generated inside the heat pump equipment and then transported to indoor terminals (such as fan coils) or floor heating through water pipes. When cooling in summer, the cold water circulates to lower the indoor temperature; when heating in winter, the hot water supplies heat through the floor heating coil. Since the heat pump equipment is outdoors and freon only circulates inside the heat pump equipment without entering the room, and heat transfer is achieved by using cold water or hot water, it can effectively avoid poisoning caused by refrigerant leakage, and the sky-water and ground-water system has higher safety. When installing the heat pump equipment, it is necessary to externally connect fan coils, floor heating, etc. Therefore, the heat pump equipment needs to be wired. Due to the limitation of the installation space in the household environment, the structure of the heat pump equipment is more compact, resulting in increased wiring difficulty and low installation efficiency.

[0030] To solve the above technical problems, an embodiment of the present invention provides an electric control box assembly, which can facilitate the operator to wire the electric control box assembly. The electric control box assembly of the embodiment of the present invention will be introduced below with reference to the accompanying drawings.

[0031] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0032] An electric control box assembly 260 according to an embodiment of the present invention can be applied to a heat pump device 1000. The heat pump device can be a water heater, which is generally used to connect to heating and ventilation terminals such as fan coils and floor heating. The water heater and the heating and ventilation terminals can be configured as a sky-water and ground-water system or a sky-fluorine and ground-water system, etc. The water heater includes a housing 100, a circuit module 200, a fan 300, a fluorine circuit module 400, a water circuit module 500, and a compressor 600.

[0033] The electric control box assembly 260 of the present embodiment includes a circuit board and a protective cover plate 230. For example, the circuit board can be a water circuit wiring board 210 or a main control board 250, etc. For the convenience of description, all subsequent embodiments will be explained by taking the circuit board as the water circuit wiring board 210 as an example.

[0034] In the heat pump device 1000 of this embodiment, the waterway wiring board 210 is provided with a wiring position 211, and the wiring position 211 is located at the edge of the waterway wiring board 210. The protective cover plate 230 is covered and installed on the side of the waterway wiring board 210 where the wiring position 211 is located. The protective cover plate 230 can effectively protect various electronic components on the waterway wiring board 210, such as protective capacitors, resistors, control chips, etc. Refer to Figure 4 , Figure 5 and Figure 6 As shown, the protective cover plate 230 is provided with a notch 231, and the notch 231 is used to expose at least part of the wiring position 211. For example, the notch 231 is used to expose all of the wiring position 211. The protective cover plate 230 includes a flipping part 232, and the flipping part 232 is rotatably connected to the notch 231 and can flip towards the outside of the protective cover plate 230. The flipping part 232 has a covering state and an open state. When the flipping part 232 is in the covering state, it can cover the wiring position 211. When the flipping part 232 is in the open state, it can open the notch 231 so that the wiring position 211 is exposed from the protective cover plate 230.

[0035] Adopting the above solution, when wiring needs to be carried out on the waterway wiring board 210, by rotating the flipping part 232 to make the flipping part 232 in the open state to expose the wiring position 211, it is not necessary to disassemble the entire protective cover plate 230, and it is also convenient for the operator to carry out wiring, with high wiring efficiency. After the wiring is completed, the flipping part 232 can be covered to the covering state, and the installation is convenient and fast. Since the protective cover plate 230 still covers the waterway wiring board 210, and only the flipping part 232 is opened to expose the wiring position 211, the protective cover plate 230 still has a protective effect on the electronic components such as capacitors, resistors, and control chips that it covers, and can effectively reduce the situation that the wiring tool accidentally touches other positions of the waterway wiring board 210, thereby reducing the probability of misoperation and improving the safety during wiring.

[0036] Refer to Figure 1 and Figure 2As shown in the figure, a heat pump device 1000 according to an embodiment of the present invention includes a housing 100, a fan 300, a circuit module 200, a fluorine circuit module 400, and a water circuit module 500. The housing 100 is generally square in shape, and a fan space 110 and a module space 120 are formed inside the housing 100. The fan space 110 and the module space 120 can be arranged in the left-right direction. The housing 100 is provided with mounting holes 130. For example, the mounting holes 130 are located in the upper part of the right side wall of the housing 100. The housing 100 includes an electric control cover plate 140, and the electric control cover plate 140 is detachably connected to the outside of the mounting holes 130. The fan 300 is installed in the fan space 110. For example, there are two fans 300, which are arranged at intervals in the up-down direction, so as to improve the heat exchange effect. The circuit module 200, the fluorine circuit module 400, and the water circuit module 500 are respectively installed in the module space 120. The circuit module 200 is installed at a position in the module space 120 close to the top of the housing 100, and the fluorine circuit module 400 and the water circuit module 500 are located on one side of the circuit module 200 away from the top of the housing 100.

[0037] Referring to Figure 2 As shown in the figure, the circuit module 200 includes an electric control box assembly 260. The water circuit wiring board 210 of the electric control box assembly 260 is located on the side close to the electric control cover plate 140 and is arranged facing the electric control cover plate 140. For example, the water circuit wiring board 210 is used to control the start / stop and speed of the water pump 700 to adjust the water flow rate and pressure, so as to ensure that cold water or hot water is delivered to the fan coil or floor heating as required. The water circuit wiring board 210 can also be used to control the electric valves in the water circuit, such as three-way valves and two-way valves, to switch the water flow path of the cooling / heating mode; at the same time, it can also monitor parameters such as water pressure, water temperature, and flow rate in real time and trigger a protection mechanism. Among them, after the electric control cover plate 140 is configured to be disassembled, the wiring positions 211 of the water circuit wiring board 210 are exposed in the mounting holes 130, and the operator can wire the water circuit wiring board 210 through the mounting holes 130.

[0038] With the above solution, the fan 300 rotates under the control of the circuit module 200, so that air passes through the heat pump device 1000 to achieve heat exchange. The refrigerant circuit module 400 is connected with refrigerant, and the refrigerant can be freon; the water circuit module 500 is connected with water, and the water pump 700 of the water circuit module 500 can provide power for the water, which is beneficial to the heat exchange between the refrigerant and the water through the heat exchanger, so as to heat the water into hot water or cool it into cold water. The hot water or cold water is transported to the room through the pipeline, so as to adjust the indoor temperature. Since the mounting hole 130 of the housing 100 is covered with a detachable electric control cover plate 140, and the water circuit wiring board 210 of the circuit module 200 is located on one side close to the electric control cover plate 140 and arranged facing the electric control cover plate 140, when the electric control cover plate 140 is removed, the wiring position 211 of the water circuit wiring board 210 is exposed in the mounting hole 130, which enables the operator to conveniently maintain the water circuit wiring board 210 through the mounting hole 130, such as wiring or circuit board inspection, etc., facilitating the wiring of the heat pump device 1000 with HVAC terminals such as fan coils and floor heating, reducing the parts to be disassembled, and improving the assembly efficiency. In addition, after removing the electric control cover plate 140, it is also convenient for the operator to maintain the circuit module 200.

[0039] Referring to Figure 3 As shown, in the embodiment of the present invention, the circuit module 200 further includes a bracket 220, and the water circuit wiring board 210 is fixedly connected to the bracket 220. The fixed connection method can be snap connection, fastener connection, bonding, etc., to prevent the water circuit wiring board 210 from loosening, poor contact or component detachment due to vibration or external force. The protective cover plate 230 is connected to the side of the water circuit wiring board 210 facing the electric control cover plate 140, and the protective cover plate 230 covers the water circuit wiring board 210. The protective cover plate 230 can block foreign matters such as dust, water vapor, and insects from entering, preventing circuit short-circuit or corrosion, especially when the heat pump device 1000 is exposed to rain and snow environment. At the same time, during maintenance, assembly and other links, the protective cover plate 230 can also prevent component damage caused by accidental contact of personnel or tool collision, such as sensitive components such as capacitors and relays.

[0040] Referring to Figure 3 、 Figure 4 and Figure 5As shown, in an embodiment of the present invention, the waterway wiring board 210 is provided with a wiring position 211, and the wiring position 211 is located at the edge of the waterway wiring board 210. The protective cover plate 230 has a notch 231 for exposing at least a part of the wiring position 211. Therefore, when it is necessary to wire using the wiring position 211, after opening the electric control cover plate 140, since part of the wiring position 211 is exposed in the mounting hole 130 through the notch 231, it is not necessary to disassemble the entire protective cover plate 230, and wiring can be facilitated, saving the steps of repeatedly disassembling and assembling the protective cover plate 230, greatly shortening the construction time, and improving the convenience of operation. At the same time, the risk of misoperation can also be reduced. The design of the notch 231 limits the operation range within the range of the notch 231, thereby reducing the situation of accidentally touching other circuit components and improving the safety of operation.

[0041] Referring to Figure 6 , Figure 7 and Figure 8 As shown, in an embodiment of the present invention, the protective cover plate 230 includes a flipping part 232, and the flipping part 232 is rotatably connected to the notch 231 and can flip towards the outside of the protective cover plate 230. The flipping part 232 has a closed state and an open state. For example, Figure 7 as shown, the flipping part 232 is in the closed state to close the notch 231 and block the wiring position 211, which can play a protective role for the wiring position 211 and effectively reduce the interference of dust, rain, and insects. For example, Figure 8 as shown, the flipping part 232 is in the open state to open the notch 231, so that the wiring position 211 is exposed in the mounting hole 130. Therefore, the flipping part 232 only exposes part of the structure of the waterway wiring board 210 (such as the wiring position 211), preventing other components from being knocked during misoperation and improving the safety of operation. It can be understood that in order to achieve flipping, the flipping part 232 can be connected to the protective cover plate 230 through a hinge. As an alternative embodiment, the protective cover plate 230 is configured to be made of plastic, and the rotating connection part of the flipping part 232 is integrally thinned on the outside of the protective cover plate 230 along the direction of its rotation axis; or the rotating connection part of the flipping part 232 is intermittently thinned on the outside of the protective cover plate 230 along the direction of its rotation axis; or the rotating connection part of the flipping part 232 is intermittently cut off the protective cover plate 230 along the direction of its rotation axis; the processing of the plastic protective cover plate 230 is simpler, which can reduce the manufacturing cost and reduce the assembly steps.

[0042] Referring to Figure 5As shown in the figure, in the embodiment of the present invention, there are two wiring positions 211, and each wiring position 211 includes a plurality of wiring terminals. One of the wiring positions 211 is located at the lower end of the waterway wiring board 210 and extends in the front-rear direction; the other is located on the front side of the waterway wiring board 210 and extends in the up-down direction. There are two flipping parts 232, and the two flipping parts 232 correspond to the positions of the two wiring positions 211 respectively and are located on two adjacent side walls of the protective cover plate 230. Among them, the protective cover plate 230 is provided with notches 231 at the corresponding positions of the wiring positions 211, so that both wiring positions 211 can be exposed in the notches 231 or blocked by the flipping parts 232, which can improve the convenience and protection of wiring.

[0043] In order to facilitate restricting the position of the flipping part 232 when it is in the open state, refer to Figure 9 , Figure 10 and Figure 11 As shown in the figure, in the embodiment of the present invention, a second buckle 233 is provided on the outer side of the flipping part 232, and a second buckle position 234 is provided on the outer side of the protective cover plate 230. When the flipping part 232 is in the open state, the second buckle 233 can be snapped with the second buckle position 234, so as to restrict the position of the flipping part 232 and keep it in the open state, which is beneficial for subsequent operators to wire, reduce the influence of the flipping part 232 on wiring, and improve the convenience of operation. When the wiring is completed, rotate the flipping part 232 to separate the second buckle 233 from the second buckle position 234. It should be noted that the positions of the second buckle position 234 and the second buckle 233 can be interchanged, that is, the second buckle position 234 is provided on the outer side of the flipping part 232, and the second buckle 233 is provided on the outer side of the protective cover plate 230, and a suitable solution is selected according to the actual situation.

[0044] Refer to Figure 12 and Figure 13 As shown in the figure, in the embodiment of the present invention, when there are two flipping parts 232, second buckles 233 are respectively provided on the outer sides of the two flipping parts 232, and two second buckle positions 234 are respectively provided at the corresponding positions on the outer side of the protective cover plate 230, so that when the two flipping parts 232 are opened, they can both be fixed by the snapping of the second buckles 233 and the second buckle positions 234. It should be noted that in addition to the snapping method for fixing the flipping part 232, it can also be fixed by magnetic attraction connection or screw connection, and a suitable solution is selected according to the actual situation.

[0045] Refer to Figure 6As shown, in the embodiment of the present invention, a retaining edge 235 is provided on the inner side of the protective cover plate 230, and the retaining edge 235 extends towards the waterway wiring board 210 to the inner side of the wiring position 211. Since tools such as screwdrivers may be used during wiring, in order to prevent the screwdriver from touching components such as capacitors, resistors, and control chips on the waterway wiring board 210, by providing the retaining edge 235 on the inner side of the protective cover plate 230 and the retaining edge 235 being located on the inner side of the wiring position 211, tools such as screwdrivers are blocked from penetrating deep into the inner side of the protective cover plate 230, effectively improving the safety and reliability during wiring.

[0046] Refer to Figure 6 and Figure 8 As shown, in the embodiment of the present invention, the flipping part 232 is provided with a third buckle 221, the bracket 220 includes a circuit board base 222, and the circuit board base 222 is provided with a third buckle position 236. When the flipping part 232 is in the closed state, the third buckle 221 is snapped with the third buckle position 236. By adopting the snap connection method, the disassembly and assembly of the flipping part 232 are more convenient, no screws need to be screwed, and the assembly efficiency is higher. At the same time, it can effectively limit the position of the flipping part 232 in the closed state, prevent the flipping part 232 from shaking, improve the protection effect of the flipping part 232 on the wiring position 211, and improve safety.

[0047] Refer to Figure 14 、 Figure 15 and Figure 16 As shown, in the embodiment of the present invention, a plug-in part 223 extending upward is provided on the top of the circuit board base 222, and a jack 237 is provided on the top of the protective cover plate 230. The plug-in part 223 is inserted into the jack 237 to determine the relative position between the protective cover plate 230 and the circuit board base 222, playing a positioning role. First buckles 224 are respectively provided on both sides of the circuit board base 222, and first buckle positions 238 corresponding to the first buckles 224 one by one are respectively provided on both sides of the protective cover plate 230. The first buckles 224 and the first buckle positions 238 are snapped to fix the relative position between the protective cover plate 230 and the circuit board base 222. Therefore, when installing the protective cover plate 230, first insert the plug-in part 223 into the jack 237 for positioning, and then press the protective cover plate 230 under the action of an external force so that the first buckles 224 and the first buckle positions 238 are snapped, thereby fixing the position of the protective cover plate 230. The operation is simple and can improve the installation efficiency of the protective cover plate 230. It should be noted that the positions of the first buckles 224 and the first buckle positions 238 can be interchanged. For example, first buckle positions 238 are respectively provided on both sides of the circuit board base 222, and first buckles 224 corresponding to the first buckle positions 238 are respectively provided on both sides of the protective cover plate 230, which can also facilitate the snap connection between the protective cover plate 230 and the circuit board base 222. Specifically, select a suitable method according to the actual situation.

[0048] Refer to Figure 16As shown, in the embodiment of the present invention, a guiding groove 239 is further provided at the first fastening position 238. The guiding groove 239 is located between two notches 231 on the protective cover plate 230. The guiding groove 239 extends along the clamping direction of the first buckle 224. For example, the guiding groove 239 extends along the left - right direction. Therefore, when the first buckle 224 is clamped, it is guided to the first fastening position 238 through the guiding groove 239, so as to smoothly engage with the first fastening position 238, which can further improve the accuracy of clamping and the installation efficiency.

[0049] Referring to Figure 17 、 Figure 18 and Figure 19 As shown, in the embodiment of the present invention, the circuit board base 222 is provided with a wire - passing board 240 arranged opposite to the wiring position 211. The wire - passing board 240 is located outside the wiring position 211 and has the same extending direction as the corresponding wiring position 211. The wire - passing board 240 is provided with a plurality of knockout holes 241 arranged at intervals along the arrangement direction of the wiring position 211. It should be noted that a plurality of wiring terminals can be connected to a plurality of cables. When connecting the cables and the wiring terminals, it is necessary to remove the external plastic - sealed wire sheath. When the removed wire sheath is relatively long, it may cause the exposed conductors of adjacent cables to be connected, resulting in short - circuits, inaccurate detection, etc. Therefore, by providing the wire - passing board 240, different cables pass through different knockout holes 241 of the wire - passing board 240, and are isolated by the ribs between the knockout holes 241, effectively preventing the exposed conductors from contacting each other, thereby improving the safety and reliability during wire routing. Each knockout hole 241 in this embodiment corresponds to two wiring terminals. Since two wiring terminals are in a group, and each group of wiring terminals controls different control units (such as ball valves, sensors, etc.) of different HVAC terminals, through the isolation of the ribs between the knockout holes 241, problems such as short - circuits or inaccurate detection between control units can be effectively avoided.

[0050] Referring to Figure 19 As shown, in the embodiment of the present invention, the wire - passing board 240 is provided with a plurality of knockout plates 242, and the knockout plates 242 are matched with the plurality of knockout holes 241. The outer contour of the knockout plate 242 is spaced from the inner wall of the knockout hole 241, and the knockout plate 242 is fixedly connected to the inner wall of the knockout hole 241 through at least one connecting strip 243. For example, the knockout plate 242 can be fixedly connected to the inner wall of the knockout hole 241 through one or two connecting strips 243. When it is necessary to route wires through the knockout hole 241, the knockout plate 242 at the corresponding position can be unscrewed, while the knockout plates 242 of the knockout holes 241 where wire routing is not required can be retained, so as to be hermetically matched with the protective cover plate 230 to improve the protection effect.

[0051] Referring to Figure 19 、 Figure 20 and Figure 21As shown, in the embodiment of the present invention, the minimum length of the connecting strip 243 along the circumferential direction of the knockout hole 241 is a, satisfying: 1.5 mm ≤ a ≤ 2.5 mm. For example, the value of a can be 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.5 mm, etc. The minimum thickness of the connecting strip 243 is b, satisfying: 0.3 mm ≤ b ≤ 0.7 mm. For example, the value of b can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, etc. It should be noted that the thickness direction of the connecting strip 243 is perpendicular to the length direction of the connecting strip 243. When a is less than 1.5 mm and b is less than 0.3 mm, the connection strength of the connecting strip 243 is weak, and it is easy to directly break off due to vibration or other reasons during the transportation of the heat pump device 1000. When a is greater than 2.5 mm and b is greater than 0.7 mm, the connection strength of the connecting strip 243 is strong, and it is difficult for the operator to break off the knockout plate 242, resulting in an increase in the wiring difficulty. Therefore, reasonably designing the value of a within the range of 1.5 mm to 2.5 mm and the value of b within the range of 0.3 mm to 0.7 mm can ensure that the knockout plate 242 will not easily become loose and can also facilitate the operator to break it off smoothly, improving the assembly efficiency.

[0052] Referring to Figure 17 As shown, in the embodiment of the present invention, the circuit board base 222 is provided with a first mounting position 2221 and a second mounting position 2222. The second mounting position 2222 is located inside the first mounting position 2221. The volume of the water circuit wiring board 210 to be installed in the second mounting position 2222 is smaller than the volume of the water circuit wiring board 210 to be installed in the first mounting position 2221. It can be understood that the second mounting position 2222 and the first mounting position 2221 are configured as mounting positions on the bottom wall of the circuit board base 222. Therefore, the area of the second mounting position 2222 is smaller than the area of the first mounting position 2221. Therefore, the circuit board base 222 can be compatible with large-size or small-size water circuit wiring boards 210, meeting the installation requirements of different models and improving the versatility of the circuit board base 222. For example, the small-sized water circuit wiring board 210 installed in the second mounting position 2222 is suitable for low-load scenarios, such as small-sized residential houses or single-zone control, reducing the equipment redundancy cost. The large-sized water circuit wiring board 210 installed in the first mounting position 2221 can match high-power requirements, such as whole-house heating in villas or commercial places, ensuring the heat exchange efficiency and system stability.

[0053] Referring to Figure 3As shown, in the embodiments of the present invention, the circuit module 200 further includes a main control board 250. The bracket 220 includes a main board base 225 for mounting the main control board 250 and a circuit board base 222 for mounting the waterway wiring board 210. The main board base 225 and the circuit board base 222 are arranged at intervals in a direction away from the fan space 110. Both the main control board 250 and the waterway wiring board 210 are heat-generating components. The spaced arrangement can improve the superposition of the heat of the two in a limited space, reduce the risk of local high temperature, avoid the accelerated aging of components such as capacitors and relays caused by high temperature, and improve the reliability of the system. At the same time, the strong electrical lines and the weak electrical signal lines can be routed along the main board base 225 and the circuit board base 222 respectively, reducing cross interference. The main control board 250 and the waterway wiring board 210 are independently installed, and there is no need to disassemble the circuit module 200 as a whole during maintenance or upgrade, reducing the operation complexity. In some embodiments, part of the pipeline of the fluorine circuit module 400 is arranged in the space between the main board base 225 and the circuit board base 222, making the overall structure of the heat pump device 1000 more compact, which is beneficial to the miniaturization of the heat pump device 1000.

[0054] Referring to Figure 2 As shown, in the embodiments of the present invention, the heat pump device 1000 further includes a compressor 600. The waterway module 500 is located at a position close to the bottom of the housing 100. The fluorine circuit module 400 and the compressor 600 are installed between the circuit module 200 and the waterway module 500, and the waterway module 500 is located at the bottommost of the module space 120. Since the compressor 600 is installed in the middle and is connected to the housing 100 through an elastic shock pad, it is beneficial to absorb the vibration energy during the operation of the compressor 600 and reduce the resonance noise transmitted to the housing 100. Moreover, the weight of the compressor 600 is in the middle, forming a symmetric layout with the bottom waterway module 500, reducing the risk of equipment tilt. Since the waterway module 500 is located at the bottommost, if water leakage occurs, the water will naturally flow downward and drain out from the bottom drain hole, avoiding soaking the upper circuit module 200 or fluorine circuit module 400 and reducing the risk of short circuit or corrosion.

[0055] Referring to Figure 1 and Figure 2As shown, in an embodiment of the present invention, the heat pump device 1000 further includes a chassis 150 and a middle partition plate 160. The middle partition plate 160 is fixedly connected to the chassis 150 and separates the fan space 110 and the module space 120, thereby reducing the influence of the air flow on the circuit module 200, the fluorine circuit module 400, and the water circuit module 500. The housing 100 further includes a top cover 101, a left front side plate 102, a right front side plate 103, a right rear side plate 104, and a maintenance plate 105. The top cover 101 is connected to the top of the middle partition plate 160. The left front side plate 102 is connected to the front side of the fan space 110. The right front side plate 103 is connected to the front side of the module space 120. The right rear side plate 104 is connected to the right side of the module space 120. An installation hole 130 is opened at the top of the right rear side plate 104. A maintenance hole 106 is provided at the bottom of the right rear side plate 104. The maintenance plate 105 is detachably arranged outside the maintenance hole 106, thereby improving the maintenance efficiency.

[0056] Referring to Figure 2 As shown, in an embodiment of the present invention, the housing 100 further includes a fixing plate 107. The fixing plate 107 is fixedly connected to the chassis 150. The fixing plate 107 is used to support the water outlet 170 and the water inlet 180 of the water circuit module 500. The fixing plate 107 can ensure that the water outlet 170 and the water inlet 180 are aligned with the external pipeline, avoid installation stress or poor sealing caused by misalignment, and improve the reliability of the heat pump device 1000.

[0058] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
