Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, and in particular to a smoke exhaust pipe and a gas water heater with a Tesla valve structure. Background Art

[0002] Nowadays, more and more people like outdoor camping activities, and many people hope to produce hot water for washing hands and taking a bath when the weather is cold. In outdoor environments, there is often wind. When the wind speed is high, it will cause the outside airflow to enter the water heater from the exhaust port. In this way, the smoke inside the water heater will flow back, inhibiting the exhaust of the smoke from the exhaust port, and even the outside airflow will flow the smoke back into the burner, causing the burner to burn incompletely, affecting the heating work, and also producing more harmful substances. Summary of the invention

[0003] The main purpose of the utility model is to provide a smoke exhaust pipe and a gas water heater with a Tesla valve structure, aiming to effectively solve the problems in the prior art.

[0004] In order to achieve the above purpose, the technical solutions of the utility model include:

[0005] The utility model discloses a smoke exhaust pipe with a Tesla valve structure, comprising:

[0006] A smoke exhaust duct, wherein the smoke exhaust duct has a smoke inlet and a smoke exhaust outlet;

[0007] A spoiler is arranged in the smoke exhaust duct and between the smoke inlet and the smoke exhaust port. The spoiler includes a through channel and a Tesla valve structure arranged on the periphery of the through channel. The Tesla valve structure includes an inner ring Tesla valve and an outer ring Tesla valve in sequence from the inside to the outside in the radial direction. The inner ring Tesla valve and the outer ring Tesla valve are both composed of multiple Tesla valve channels arranged in a ring shape.

[0008] Compared with the prior art, the utility model discloses a smoke exhaust pipe with a Tesla valve structure. A spoiler is arranged in the smoke exhaust pipe, and a Tesla valve structure is arranged on the spoiler. The Tesla valve structure is used to accelerate the fluid in the forward direction and block the fluid in the reverse direction, so that the smoke can be discharged quickly and the smoke can be prevented from being affected by the external airflow and flowing back in large quantities, thereby affecting the operation of the equipment.

[0009] Specifically, in the present invention, the Tesla valve structure includes an inner ring Tesla valve and an outer ring Tesla valve in sequence from the inside to the outside in the radial direction, so that the range of influencing the flow of the fluid can be increased, and thus the flow speed of the fluid through the through channel can be affected; when the smoke is discharged, the smoke passes through the through channel and the Tesla valve structure, and the smoke is accelerated by the Tesla valve structure. Since the discharge speed of the smoke passing through the Tesla valve structure is faster than the discharge speed of the smoke passing through the through channel, the smoke passing through the Tesla valve structure will drive the flow of the smoke passing through the through channel, and thus accelerate the discharge of the smoke passing through the through channel, playing a role in accelerating the discharge of the smoke; in addition, due to the reverse blocking characteristics of the Tesla valve structure, when the external airflow enters the exhaust pipe and passes through the spoiler, the Tesla valve channel can block the external airflow from passing through the channel, and the external airflow can only enter through the space outside the through channel and the Tesla valve channel. Since the Tesla valve structure is a double-layer structure of an inner ring and an outer ring, the range of blocking the entry of the external airflow can be increased, and the smoke is accelerated by the positive acceleration of the Tesla valve, thereby preventing a large amount of external airflow from backflowing into the interior of the device.

[0010] In a preferred embodiment, each of the Tesla valve channels includes a main channel and a plurality of resistance channels, the direction of the main channel is the same as the length direction of the smoke exhaust pipe, and the plurality of resistance channels are arranged in sequence along the length direction of the main channel and are arranged on opposite sides of the main channel.

[0011] In a preferred embodiment, the number of Tesla valve channels of the outer ring Tesla valve is greater than the number of Tesla valve channels of the inner ring Tesla valve.

[0012] In a preferred embodiment, the spoiler is arranged close to the smoke inlet.

[0013] In a preferred embodiment, the smoke exhaust port is composed of a plurality of smoke exhaust holes, and the plurality of smoke exhaust holes are located on the circumferential wall surface of the smoke exhaust pipe.

[0014] The utility model also discloses a gas water heater, comprising a shell and a smoke exhaust pipe with a Tesla valve structure as described above, wherein the shell has an opening, and wherein the shell has a burner, a heat exchanger and a smoke collecting hood which are sequentially arranged and connected from bottom to top, and wherein the smoke exhaust pipe with a Tesla valve structure is arranged outside the shell and is connected to the smoke collecting hood through the opening.

[0029] Combination Figures 1 to 3 As shown, the utility model discloses a smoke exhaust pipe with a Tesla valve structure, comprising:

[0030] A smoke exhaust pipe 1, wherein the smoke exhaust pipe 1 has a smoke inlet 11 and a smoke exhaust port 12;

[0031] The spoiler 2 is arranged in the smoke exhaust duct 1 and between the smoke inlet 11 and the smoke exhaust port 12. The spoiler 2 includes a through channel 21 and a Tesla valve structure 22 arranged on the periphery of the through channel 21. The Tesla valve structure 22 includes an inner ring Tesla valve 221 and an outer ring Tesla valve 222 in sequence from the inside to the outside in the radial direction. The inner ring Tesla valve 221 and the outer ring Tesla valve 222 are both composed of multiple Tesla valve channels 223 arranged in a ring shape.

[0032] Compared with the prior art, the utility model discloses a smoke exhaust pipe with a Tesla valve structure 22, in which a spoiler 2 is arranged in the smoke exhaust pipe 1, and a Tesla valve structure 22 is arranged on the spoiler 2. The Tesla valve structure 22 is used to accelerate the fluid in the forward direction and block the fluid in the reverse direction, so that the smoke can be discharged quickly and the smoke can be prevented from being affected by the external airflow and flowing back in large quantities, thereby affecting the operation of the equipment.

[0033] Specifically, in the present invention, the Tesla valve structure 22 includes an inner ring Tesla valve 221 and an outer ring Tesla valve 222 in sequence from the inside to the outside in the radial direction, so that the range of affecting the flow of the fluid can be increased, and then the flow speed of the fluid through the through channel 21 can be affected; when the smoke is discharged, the smoke passes through the through channel 21 and the Tesla valve structure 22, and the smoke is accelerated by the Tesla valve structure 22. Since the discharge speed of the smoke passing through the Tesla valve structure 22 is faster than the discharge speed of the smoke passing through the through channel 21, the smoke passing through the Tesla valve structure 22 will drive the smoke passing through the through channel 21 to flow. , thereby accelerating the discharge of smoke passing through the through-channel 21, thereby accelerating the discharge of smoke; in addition, due to the reverse blocking characteristics of the Tesla valve structure 22, when the external airflow enters the exhaust pipe through the spoiler 2, the Tesla valve channel 223 can block the external airflow from passing through the channel, and the external airflow can only enter through the through-channel 21 and the space outside the Tesla valve channel 223. Since the Tesla valve structure 22 is a double-layer structure of an inner ring and an outer ring, the range of blocking the entry of external airflow can be increased, and the smoke is subject to the positive acceleration of the Tesla valve, thereby preventing a large amount of external airflow from backflowing into the interior of the equipment.

[0034] In one embodiment, each of the Tesla valve channels 223 includes a main channel 2231 and a plurality of resistance channels 2232, the direction of the main channel 2231 being the same as the length direction of the smoke exhaust pipe 1, and the plurality of resistance channels 2232 being sequentially arranged along the length direction of the main channel 2231 and arranged on opposite sides of the main channel 2231. When smoke flows from the smoke inlet 11 to the smoke exhaust port 12 through the Tesla valve structure 22, part of the smoke can be diverted through the resistance channel 2232 and then merged into the main channel 2231 to increase the flow velocity of the smoke; when smoke flows from the smoke exhaust port 12 to the smoke inlet 11 through the Tesla valve structure 22, part of the smoke can be diverted through the resistance channel 2232 and then merged into the main channel 2231 to reduce the flow velocity of the smoke.

[0035] In one embodiment, the number of Tesla valve channels 223 of the outer ring Tesla valve 222 is greater than the number of Tesla valve channels 223 of the inner ring Tesla valve 221, so that the smoke velocity level can be divided into three layers. The smoke velocity passing through the outer ring Tesla valve 222 is the fastest, the smoke velocity passing through the inner ring Tesla valve 221 is the second fastest, and the smoke velocity passing through the through-channel 21 is the slowest. The smoke passing through the outer ring Tesla valve 222 can drive the flow of the smoke passing through the inner ring Tesla valve 221, thereby accelerating the smoke passing through the inner ring Tesla valve 221. The smoke passing through the inner ring Tesla valve 221 can drive the flow of the smoke passing through the through-channel 21, thereby accelerating the smoke passing through the through-channel 21, thereby accelerating the exhaust of the smoke as a whole.

[0036] Preferably, the number of Tesla valve channels 223 of the outer ring Tesla valve 222 is twice the number of Tesla valve channels 223 of the inner ring Tesla valve 221. In the present invention, the number of Tesla valve channels 223 of the outer ring Tesla valve 222 is 8, and the number of Tesla valve channels 223 of the inner ring Tesla valve 221 is 4.

[0037] In one embodiment, the spoiler 2 is disposed close to the smoke inlet 11. After the smoke fluid enters the smoke exhaust pipe 1 through the smoke inlet 11, it can quickly contact the spoiler 2, thereby quickly exhausting the smoke fluid.

[0038] In one embodiment, the smoke exhaust port 12 is composed of a plurality of smoke exhaust holes, and the plurality of smoke exhaust holes are located on the circumferential wall surface of the smoke exhaust pipe 1. When air is introduced and smoke is exhausted, the external air, when passing through the smoke exhaust holes, reduces the sound waves in the air through the acoustic impedance of the plurality of smoke exhaust holes, and plays a certain role in silencing and reducing noise; and in the process of air introduction, the wall surface of the smoke exhaust pipe 1 connecting the plurality of smoke exhaust holes will block the airflow, and play a certain role in preventing backwind. It should be noted that backwind refers to the external airflow entering the smoke exhaust pipe, and the smoke to be discharged is backflowed into the equipment.

[0039] Combination Figures 1 to 4 As shown, the utility model also discloses a gas water heater, including a shell 3 and a smoke exhaust pipe with a Tesla valve structure as described above, the shell 3 has an opening, the shell 3 has a burner, a heat exchanger and a smoke hood arranged and connected in sequence from bottom to top, and the smoke exhaust pipe with a Tesla valve structure 22 is arranged outside the shell 3 and is connected to the smoke hood through the opening. The smoke generated after the combustion in the gas water heater flows into the smoke hood, and then is discharged to the external environment through the smoke exhaust pipe. During the exhaust process of the smoke, the Tesla valve structure 22 accelerates the exhaust of the smoke; when the external airflow is poured into the smoke exhaust pipe, the Tesla valve structure 22 blocks the external airflow, preventing a large amount of external airflow from backflowing the smoke into the burner through the smoke hood and the heat exchanger, thereby interfering with the operation of the burner.

[0040] In one embodiment, the housing 3 is connected to the smoke exhaust pipe via a flexible pipe 4. Thus, by rotating the flexible pipe 4, the position of the smoke exhaust pipe can be changed, so that the user can choose the placement position of the smoke exhaust pipe, which is convenient for the user to use.

[0041] Preferably, the flexible tube 4 can be a corrugated tube, a galvanized hose, etc.

[0042] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
