Description

Technical Field

[0001] The invention relates to the technical field of water heaters, and in particular to a water heater and an ultrasonic descaling and anti-corrosion device. Background Art

[0002] In order to prevent the inner wall of the water heater tank from being corroded, the current method is to use a sacrificial anode to protect the cathode. Specifically, a metal anode is set in the water heater tank, and the liquid in the water heater tank is used as a medium to transfer the electrons on the metal anode to the water heater tank. That is, the metal anode undergoes an oxidation reaction instead of the water heater tank, thereby replacing the water heater tank that is corroded and consumed.

[0003] However, in actual use, the applicant has found that even when the metal anode in the water heater tank is still within its service life, the water heater tank will still be corroded. Summary of the invention

[0004] The purpose of the present invention is to provide an ultrasonic descaling and anti-corrosion device, which can effectively solve the problems existing in the prior art.

[0005] In order to achieve the above object, the technical solution of the present invention is:

[0006] An ultrasonic descaling and anti-corrosion device, comprising:

[0007] Ultrasonic generator;

[0008] A vibrating rod connected to the ultrasonic generator and used to emit ultrasonic waves in the inner tank of the water heater;

[0009] The vibrating rod comprises a first vibrating rod connected to the inner tank of the water heater;

[0010] When the first vibrating rod contacts the liquid in the inner tank of the water heater, the first vibrating rod constitutes a sacrificial anode and the inner tank of the water heater constitutes a protective cathode.

[0011] The ultrasonic descaling and anti-corrosion device of the present invention is connected to an ultrasonic generator through a vibrating rod, and is used to emit ultrasonic waves in the inner tank of a water heater, so as to cause a cavitation effect on the liquid in the inner tank, thereby preventing scale and dirt from adhering to the surfaces of various components in the inner tank, and preventing the inner tank of the water heater from being corroded by scale and dirt adhering to the surface;

[0012] Furthermore, since the vibrating rod includes a first vibrating rod, when the first vibrating rod contacts the liquid in the inner tank, the first vibrating rod constitutes a sacrificial anode and the inner tank of the water heater constitutes a protective cathode, so that the first vibrating rod is corroded instead of the inner tank of the water heater;

[0013] Furthermore, since ultrasound is a mechanical wave, the vibrating rod is vibrating while emitting ultrasound, and therefore the first vibrating rod is also vibrating, so that the rust on the first vibrating rod caused by corrosion will automatically fall off, so that the uncorroded part of the first vibrating rod is in full contact with the liquid, effectively solving the problem of rust on the outer layer of the metal anode, the rust layer blocking the oxidation reaction of the metal anode and thus affecting the anti-corrosion function of the metal anode, causing corrosion of the inner tank of the water heater.

[0014] As a specific implementation, the vibration rod further includes an ultrasonic transducer connected to the ultrasonic generator, and the ultrasonic transducer is used to generate ultrasonic waves and transmit the ultrasonic waves to the first vibration rod.

[0015] Specifically, the first vibration rod is made of magnesium.

[0016] Further, the vibrating rod further comprises a second vibrating rod embedded in the first vibrating rod, and the second vibrating rod is connected to the ultrasonic transducer;

[0017] When the second vibrating rod is in contact with the liquid in the inner tank of the water heater, the second vibrating rod does not constitute a sacrificial anode.

[0018] The ultrasonic descaling and anti-corrosion device of the present invention has a second vibrating rod embedded in a first vibrating rod, and an ultrasonic transducer is connected to the second vibrating rod. Since the second vibrating rod does not constitute a sacrificial anode when in contact with the liquid in the inner tank of the water heater, even after the first vibrating rod is completely corroded, the device can continue to emit ultrasonic waves through the second vibrating rod, so that the liquid in the inner tank continues to produce a cavitation effect, thereby removing scale and dirt attached to the surfaces of various components in the inner tank.

[0019] Specifically, the second vibration rod is a hollow cylinder, and at least one ultrasonic transducer is provided on the inner wall of the hollow cylinder.

[0020] The ultrasonic descaling and anti-corrosion device of the present invention has a second vibrating rod which is a hollow cylinder. By arranging the ultrasonic transducer in the hollow cylinder, the ultrasonic transducer can still be protected in the hollow cylinder to avoid damage.

[0021] Furthermore, the ultrasonic transducer is connected to the ultrasonic generator via a waterproof wire.

[0022] Furthermore, the ultrasonic descaling and anti-corrosion device also includes a connecting seat, the vibrating rod is fixed on the connecting seat, and the connecting seat is detachably connected to the sewage outlet on the inner tank of the water heater.

[0023] Furthermore, the ultrasonic descaling and anti-corrosion device also includes: a sealing component, which is arranged between the connecting seat and the inner wall of the sewage outlet.

[0024] The present invention also provides a water heater, which comprises: a water heater inner tank, and the ultrasonic descaling and anti-corrosion device mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 4 It is a schematic diagram of the structure of the ultrasonic descaling and anti-corrosion device of Example 2 of the present invention. DETAILED DESCRIPTION

[0029] In order to better illustrate the present invention, the following Figure 1-4 The present invention is described in further detail.

[0030] Example 1

[0031] like Figure 1 As shown, an ultrasonic descaling and anti-corrosion device comprises:

[0032] Ultrasonic generator 1;

[0033] A vibrating rod 2, which is connected to the ultrasonic generator 1 and is used to emit ultrasonic waves in the inner tank of the water heater;

[0034] The vibrating rod 2 comprises a first vibrating rod 201 connected to the inner tank of the water heater;

[0035] like Figure 2 As shown, when the first vibrating rod 2 contacts the liquid in the water heater inner tank 3, the first vibrating rod 2 constitutes a sacrificial anode and the water heater inner tank 3 constitutes a protective cathode.

[0036] Specifically, the vibration rod 2 also includes an ultrasonic transducer 203 connected to the ultrasonic generator 1, and the ultrasonic transducer 203 is used to convert the electrical signal provided by the ultrasonic generator into a mechanical wave, and transmit the mechanical wave to the first vibration rod 201 to make the first vibration rod 201 vibrate.

[0037] Specifically, the first vibration rod 201 is made of magnesium.

[0038] It should be noted that, in this specific embodiment, the first vibration rod 2 is made of magnesium, which is only an example of this embodiment and is not a limitation of this embodiment. For example, the first vibration rod 2 can be made of aluminum.

[0039] Preferably, the ultrasonic descaling and anti-corrosion device further includes a connecting seat 4 , the vibrating rod 2 is fixed on the connecting seat 4 , and the connecting seat 4 is detachably connected to the drain outlet 301 on the inner tank 3 of the water heater.

[0040] Among them, since the connecting seat 4 is detachably connected to the drain port 301 on the water heater inner tank 3, when the sewage in the water heater inner tank 3 needs to be discharged, the vibrating rod 2 can be removed together to make the sewage flow out from the drain port 301, which is convenient for sewage discharge.

[0041] Specifically, the ultrasonic transducer 203 is connected to the ultrasonic generator 1 via a waterproof wire 5. By arranging the ultrasonic generator 1 at a location where the water heater is easily accessible to the user, the user's operation is convenient.

[0042] Since there is water in the water heater, the ultrasonic generator 1 and the ultrasonic transducer 203 are connected by a waterproof wire to avoid leakage and the like.

[0043] Specifically, the specific model of the waterproof wire 5 is FS-DJYP3VP3; it should be noted that this does not mean a limitation on the model of the waterproof wire.

[0044] Preferably, if Figure 3 As shown, the ultrasonic descaling and anti-corrosion device also includes a sealing component 6, which is arranged between the connecting seat 4 and the inner wall of the sewage outlet 302.

[0045] The ultrasonic descaling and anti-corrosion device of this embodiment is connected to an ultrasonic generator via a vibrating rod, and is used to emit ultrasonic waves in the inner tank of the water heater to produce a cavitation effect on the liquid in the inner tank, thereby preventing scale and dirt from adhering to the surfaces of various components in the inner tank, thereby preventing the inner tank of the water heater from being corroded by scale and dirt attached to the surface.

[0046] After careful observation, the applicant found that the reason why the inner tank of the water heater still corrodes after the metal anode is installed is that during use, the metal anode is corroded and its outer layer gradually turns into rust, and the rust generally does not fall off without a strong water flow impact, thereby blocking the release of water and air from the unoxidized part of the inner layer of the metal anode, thereby slowing down the speed of the oxidation reaction and affecting the anti-corrosion function of protecting the metal body.

[0047] Furthermore, since the vibrating rod of this embodiment includes a first vibrating rod, and when the first vibrating rod contacts the liquid in the inner tank, the first vibrating rod constitutes a sacrificial anode and the inner tank of the water heater constitutes a protective cathode, so that the first vibrating rod is corroded instead of the inner tank of the water heater;

[0048] Furthermore, since ultrasound is a mechanical wave, the vibrating rod is vibrating while emitting ultrasound, and therefore the first vibrating rod is also vibrating, so that the rust on the first vibrating rod caused by corrosion will automatically fall off, so that the uncorroded part of the first vibrating rod is in full contact with the liquid, effectively solving the problem of rust on the outer layer of the metal anode, the rust layer blocking the oxidation reaction of the metal anode and thus affecting the anti-corrosion function of the metal anode, causing corrosion of the inner tank of the water heater.

[0049] The present invention further provides a water heater, comprising: a water heater inner tank 3, and any one of the above-mentioned ultrasonic descaling and anti-corrosion devices.

[0050] like Figure 2 As shown, the control panel 7 for controlling the ultrasonic generator 1 in the ultrasonic descaling and anti-corrosion device is fixed on the shell of the water heater, so that the user can operate it. The ultrasonic generator 1 is fixed between the shell of the water heater and the inner tank of the water heater.

[0051] Example 2

[0052] This embodiment is basically the same as Embodiment 1, except that:

[0053] like Figure 4 As shown, the vibrating rod 2 further includes a second vibrating rod 202 embedded in the first vibrating rod 201, and the second vibrating rod 202 is connected to the ultrasonic transducer 203;

[0054] When the second vibrating rod 202 contacts the liquid in the water heater inner tank 3 , the second vibrating rod 202 does not constitute a sacrificial anode.

[0055] The ultrasonic descaling and anti-corrosion device of this embodiment has a second vibrating rod embedded in the first vibrating rod, and the ultrasonic transducer is connected to the second vibrating rod. Since the second vibrating rod does not constitute a sacrificial anode when in contact with the liquid in the inner tank of the water heater, even after the first vibrating rod is completely corroded, the device can continue to emit ultrasonic waves through the second vibrating rod, so that the liquid in the inner tank continues to produce cavitation effect, thereby removing scale and dirt attached to the surfaces of various components in the inner tank.

[0056] Specifically, Figure 4 As shown, the second vibration rod 202 is a hollow cylinder, and at least one ultrasonic transducer 202 is provided on the inner wall of the hollow cylinder.

[0057] The ultrasonic descaling and anti-corrosion device of this embodiment has a second vibrating rod that is a hollow cylinder. By arranging the ultrasonic transducer in the hollow cylinder, the ultrasonic transducer can still be protected in the hollow cylinder to avoid damage.
