[0024] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.
[0025] Example 1:
[0026] See attached Figure 1-3 A dynamic condensation net 1 of the present invention is shown, comprising a condensation net body, the condensation net body comprising a mounting portion 2, an outer frame 3 and spokes 4, wherein the outer frame 3 is arranged outside the mounting portion 2, the spokes are connected between the mounting portion 2 and the outer frame 3 and are distributed circumferentially, a water system is arranged in the outer frame 3 and the spokes, and a water inlet and a water outlet connected to the water system are arranged on the mounting portion 2.
[0027] Preferably, the spokes 4 include main spokes 41 and secondary spokes 42. The main spokes 41 are connected between the mounting portion 2 and the outer frame 3. The secondary spokes 42 are provided between two adjacent main spokes 41. The main spokes 41 and secondary spokes 42 are arranged closely between the mounting portion 2 and the outer frame 3. The physical interception method is used to increase the contact area between the oil smoke and the dynamic condensation network 1, so that the oil droplets condense and the grease is separated from the oil smoke. The water system includes a main slot hole provided in the main spoke 41, a secondary slot hole provided in the secondary spoke 42, and a connecting hole provided on the outer frame 3. The connecting hole connects the main slot hole and the secondary slot hole. Cold water or other refrigerant can flow into the main slot hole and the secondary slot hole, and the grease in the oil smoke is condensed by condensation, thereby improving the grease separation degree of the range hood. Preferably, a first middle partition is provided in the main spoke 41, and the first middle partition divides the main slot hole in the main spoke 41 into an upper main slot hole 411 and a lower main slot hole 412. A second middle partition is provided in the secondary spoke 42, and the second middle partition divides the spoke slot hole in the secondary spoke 42 into an upper spoke slot hole 421 and a lower spoke slot hole 422. The connecting hole connects the upper main slot hole 411 and the lower main slot hole 412.
[0028] Preferably, the upper main slots 411 and the upper spoke slots 421 are interconnected, the lower main slots 412 and the lower spoke slots 422 are interconnected, the water inlet is connected to the lower main slots 412, and the water outlet is connected to the upper main slots 411. Cold water or other refrigerant enters the dynamic condensation network 1 from the water inlet, enters the lower main slots 412 in the main spokes 41 through the water inlet, flows from the lower main slots 412 into the lower spoke slots 422 and the upper main slots 411, flows from the upper main slots 411 into the upper spoke slots 421, and finally exits the water outlet through the upper main slots 411. This keeps the dynamic network and its surrounding areas at a relatively low temperature at all times, condenses the oil in the smoke, and improves the oil separation efficiency of the range hood.
[0029] Example 2:
[0030] See attached Figure 4-7The present invention shows a range hood comprising a range hood housing 100 and a fan system 110, wherein the fan system 110 is arranged in the range hood housing 100, and the fan system 110 comprises a motor and an impeller, the motor and the impeller being connected, and the range hood comprising the aforementioned dynamic condensation net 1, which is arranged on the fan system 110 and mounted on the rotating shaft of the motor. A mounting hole is formed in the mounting portion 2, and the mounting hole is threadedly connected to the rotating shaft of the motor. The condensation net body is arranged in front of the impeller and rotates synchronously with the impeller. By rotating at high speed, the probability of collision between the dynamic condensation net 1 and the grease in the oil smoke is increased, which is equivalent to increasing the contact area between the oil smoke and the dynamic condensation net 1. In addition, a water system is provided in the dynamic condensation net 1, so that the dynamic net and its surrounding areas are always in a relatively low temperature state. The grease in the oil smoke is further separated by physical interception and condensation methods, thereby improving the grease separation degree of the range hood.
[0031] The water inlet is connected to the water inlet pipe, and the water outlet is connected to the drain pipe. Both the water inlet pipe and the drain pipe are metal pipes or hard pipes, and are fixed on the range hood housing 100 so that when the dynamic condensation net 1 rotates, the water inlet pipe and the drain pipe will not rotate accordingly.
[0032] It also includes a water inlet device 21 and a water outlet device 22, the water inlet device 21 is installed on the water inlet, and the water outlet device 22 is installed on the water outlet. The water inlet device 21 includes a water inlet connecting portion 211 and a pipe wall 212. The water inlet connecting portion 211 is provided at one end of the pipe wall 212 for connecting to the water inlet pipe. The water outlet device 22 includes a center hole 221, and the pipe wall 212 passes through the center hole 221 of the water outlet device 22. The outer wall of the pipe wall 212 is tightly connected to the inner wall of the center hole 221.
[0033] It also includes a first waterproof sealing bearing 213. The other end of the tube wall 212 is also provided with a first step portion 214. The first step portion 214 extends away from the tube wall 212 to form an assembly portion 215. The assembly portion 215 is provided with a first annular slot 216. The first annular slot 216 is used to install a water inlet shaft retaining ring. A first annular boss 217 is also provided on the water inlet. The first waterproof sealing bearing 213 is installed in the installation space formed by the first annular boss 217, the water inlet shaft retaining ring, and the first step portion 214. The water inlet shaft retaining ring, the first annular boss 217, and the first waterproof sealing bearing 213 are abutted against each other, limiting the first waterproof sealing bearing 213 from sliding inward. The first step portion 214 and the first waterproof sealing bearing 213 are abutted against each other, limiting the first waterproof sealing bearing 213 from sliding outward. This prevents water leakage at the water inlet.
[0034] The water outlet device 22 also includes a second waterproof sealed bearing 225. The water outlet device 22 is further provided with a second step 222 and a second annular slot 223. The second annular slot 223 is used to mount a water outlet shaft retaining ring. A second annular boss 224 is provided on the water outlet. The second waterproof sealed bearing 225 is mounted within the mounting space formed by the second step 222, the water outlet shaft retaining ring, and the second annular boss 224. The water outlet shaft retaining ring, the second annular boss 224, and the second waterproof sealed bearing 225 abut against each other, restricting the waterproof sealed bearing from sliding inward. The second step 222 abuts against the second waterproof sealed bearing 225, restricting the second waterproof sealed bearing 225 from sliding outward, thereby preventing water leakage at the water outlet.
[0035] The water outlet device includes an annular cavity 226, on which a drainage portion 227 is provided. A drainage pipe is connected to the drainage portion 227. An opening 228 is provided at the bottom of the annular cavity 226. Water discharged from the water outlet of the dynamic condensation network enters the annular cavity 226 of the water outlet device through the opening 228.
[0036] The condensation system 1 further includes a bearing end cap 300 and a fixing member. The bearing end cap 300 is provided with a fixing hole, through which the fixing member secures the bearing end cap 300 to the dynamic condensation network 1. This prevents the first waterproof sealed bearing 213 and the second waterproof sealed bearing 225 from sliding outward. In this embodiment, the fixing member is a bolt.
[0037] The range hood is connected to a refrigerator, with a water pump installed between the two. When the range hood is turned on, its operating principle is as follows: the motor rotates and the timer starts. If the range hood is on for less than 30 seconds, the refrigerator 11 and the water pump 12 will not operate, and water or refrigerant will not flow into the dynamic condensation network 1. If the range hood is on for more than 30 seconds, the refrigerator starts to operate, and the water pump also starts to operate, so that the chilled cold water or refrigerant enters the dynamic condensation network 1 through the water inlet pipe. The water or refrigerant is then transported back to the refrigerator through the drain pipe for refrigeration, thus circulating the water. When the range hood is turned off, the motor stops rotating and the timer starts to count. If the timer is less than 60 seconds, the refrigerator and water pump continue to operate, and the cold water or refrigerant continues to enter the dynamic condensation network 1 through the water inlet pipe. After the timer exceeds 60 seconds, the refrigerator stops operating, the water pump stops operating, and the water or refrigerant no longer circulates.
[0038] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
