Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a waterproof refrigerator light that is easy to clean. Background Technology

[0002] Refrigerator lights are a type of lighting fixture named according to their intended use. They are mainly used in cold storage, refrigerated areas, and other places with low temperatures and high humidity, where electrical safety and environmental protection are important considerations. Common refrigerator lights consist of two parts: a protective cover and a light source. Protective covers are made of materials such as cast aluminum + glass, iron + glass, or all plastic. Light sources include traditional incandescent bulbs, traditional energy-saving bulbs (fluorescent bulbs), and LED refrigerator lights.

[0003] Chinese patent CN215001121U discloses a waterproof LED freezer light that is easy to clean. The technical solution includes a lamp body and a mounting plate. The lamp body includes a lamp plate and a lampshade. The lampshade is fixedly connected to the lamp plate. A collar is slidably connected to the outer side of the lampshade, and a cleaning wipe is fixed to the inner side of the collar. The cleaning wipe is in close contact with the surface of the lampshade. A first stop and a second stop are integrally formed on the surface of the mounting plate. A limiting block is integrally formed at one end of the lampshade. A limiting groove is provided on the inner side of the first stop, and the limiting block is slidably inserted into the limiting groove. A slot is provided at the other end of the lampshade. A locking block is slidably provided on the inner side of the second stop. A spring connects the locking block and the second stop, and the locking block is slidably locked in the slot.

[0004] Traditional freezer lights often suffer from surface frost buildup during use, which obstructs the light. When the freezer is turned on or off, the outside air comes into contact with the light, causing condensation droplets to form on the surface, resulting in light distortion. The patented solution provides a structure that is easy to clean manually, but it requires manual movement and cannot be cleaned for condensation and frost when the freezer is closed.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 7 This invention provides a technical solution: a waterproof refrigerator light that is easy to clean, comprising a fixed lamp plate 1, a lamp plate fixing shaft 2, a rotating outer shell 3, a support outer shell 4, a lamp body mounting base plate 5, and a contact scraper 6. The fixed lamp plate 1 has a lamp plate fixing shaft 2 fixedly installed at both ends. The rotating outer shell 3 is fitted onto the outside of the fixed lamp plate 1. The rotating outer shell 3 can be made of materials such as glass to avoid scratches. The rotating outer shell 3 is cylindrical and can rotate. Support outer shells 4 are respectively provided at both ends of the rotating outer shell 3. The lamp plate fixing shaft 2 is fixedly installed to the support outer shell 4. The lamp body mounting base plate 5 is fixedly installed on the surface of the support outer shell 4. The contact scraper 6 is fixedly installed on the surface of the lamp body mounting base plate 5. The contact scraper 6 is elastic and makes scraping contact with the outer surface of the rotating outer shell 3. A de-icing structure is provided above the contact scraper 6. When the contact scraper 6 flips up, the de-icing structure is activated.

[0027] The de-icing structure includes a de-icing scraper 601, a positioning through hole 602, a positioning light rod 603, a scraper blade 604, a magnetic base 605, a tension spring base plate 606, a reset tension spring 607, a sleeve fixing plate 608, a fixing sleeve hole 609, and a driving electromagnet 610.

[0028] The de-icing scraper strip 601 is positioned above the contact scraper blade 6. A positioning through hole 602 is provided through the interior of the de-icing scraper strip 601. A positioning light rod 603 is inserted into the interior of the positioning through hole 602. Both ends of the positioning light rod 603 are fixedly installed on the outer surface of the support housing 4. A scraping blade 604 is fixedly provided on the side of the de-icing scraper strip 601 facing the rotating housing 3. The scraping blade 604 is thin and inclined. The scraping blade 604 is evenly distributed in a linear array on the surface of the de-icing scraper strip 601.

[0029] The magnetic base 605 is fixedly installed on the upper surface of the de-icing scraper 601. On one side of the magnetic base 605, a tension spring plate 606 is fixedly installed on the surface of the lamp body mounting base 5. A reset tension spring 607 is provided between the tension spring plate 606 and the magnetic base 605.

[0030] On the other side of the magnetic base 605, a mounting plate 608 is fixedly installed on the surface of the lamp body mounting base 5. A fixing hole 609 is opened through the surface of the mounting plate 608. A driving electromagnet 610 is fixedly installed inside the fixing hole 609. The driving electromagnet 610 is coaxially corresponding to the magnetic base 605.

[0031] LED beads 101 are fixedly installed on the surface of the fixed light panel 1. A limiting protrusion ring 201 is fixedly installed on the surface of the fixed light panel shaft 2. The limiting protrusion ring 201 is located inside the rotating housing 3. A wiring channel 202 is opened inside the fixed light panel shaft 2. The wiring channel 202 is used for wires to pass through. External wires pass through the wiring channel 202 and connect with the fixed light panel 1 to conduct electricity, so that the fixed light panel 1 emits light. A sealing ring groove 203 is opened on the surface of the fixed light panel shaft 2. A sealing rubber ring 204 is installed inside the sealing ring groove 203.

[0032] Rotary housing 3 has a rotating shaft tube 301 fixedly connected to both ends. The rotating shaft tube 301 is cylindrical. The lamp plate fixing shaft 2 passes through the rotating shaft tube 301. The outer surface of the sealing ring 204 is in sealing contact with the inner wall surface of the rotating shaft tube 301. A rotating worm gear 302 is fixedly installed at the end of the rotating shaft tube 301. A drive motor 304 is fixedly installed on the inner wall surface of the support housing 4. A drive worm 303 is fixedly installed on the rotating shaft of the drive motor 304. The drive worm 303 and the rotating worm gear 302 mesh with each other.

[0033] A shaft tube hole 401 is formed through the surface of the support housing 4, through which the rotating shaft tube 301 passes. A base plate nail hole 501 is formed through the surface of the lamp body mounting plate 5. A deformation groove 611 is formed through the surface of the contact scraper 6 near the location of the lamp body mounting plate 5. The deformation grooves 611 are evenly distributed in a linear array on the surface of the contact scraper 6. By forming the deformation grooves 611, the contact scraper 6 can be more easily deformed. A contact sensing post 612 is fixedly provided on the surface of the support housing 4. The contact sensing post 612 is located at the contact scraper. At the position above the strip 6, when the contact sensing post 612 contacts the contact scraper strip 6, it can trigger the working signal of the driving electromagnet 610. In the above structure, one end of the conducting circuit can be connected to the contact scraper strip 6, and the other end of the conducting circuit can be connected to the contact sensing post 612. Under normal circumstances, the contact sensing post 612 and the contact scraper strip 6 are not in contact, and the two are in an open switch state. When the two are in contact, the switch is turned on. After the switch is turned on and triggered, the driving electromagnet 610 works for a delay period of time. The working time can be set according to the rotation speed of the rotating housing 3 and the actual needs.

[0034] When in use, the present invention fixes the refrigerator lamp in the environment such as refrigerator and cold storage through the lamp body mounting base plate 5, drives the motor 304 to run, and transmits power through the meshing of the drive worm 303 and the rotating worm wheel 302, so that the rotating shell 3 rotates at low speed and high torque, and the fixed lamp plate 1 emits light inside the rotating shell 3 to achieve the lighting effect.

[0035] When the freezer is switched on and off, causing condensation or frost to form on the surface of the rotating outer casing 3, the rotation of the outer casing 3 allows the contact scraper 6 to remove the condensation or frost, thus preventing the light transmission and illumination effect of the rotating outer casing 3 from being affected. The rotation direction of the rotating outer casing 3 is as follows: Figure 7 As shown, it rotates clockwise.

[0036] In one scenario, when the refrigerator light of this invention has been idle in the refrigerator for a long time and is suddenly started, a large icing point will form on its surface. This icing point is difficult to remove using the scraping effect of the contact scraper 6. Therefore, when the icing point rotates to the position of the contact scraper 6, it will bend the contact scraper 6, causing it to curl upwards. When the contact scraper 6 contacts the contact sensing post 612, it will trigger a conduction signal, causing the driving electromagnet 610 to be supplied with a pulsed current, generating an intermittently fluctuating magnetic force. This magnetic force attracts the magnetic base 605 to move. When the magnetic force disappears, the magnetic base 605 is pulled back by the action of the reset spring 607, causing the magnetic base 605 to move back and forth. Since the magnetic base 605 is fixedly installed with the de-icing scraper 601, the de-icing scraper 601 will drive the scraper blade 604 to scrape axially at high frequency.

[0037] When the freezing point reaches the position of the high-frequency moving scraping blade 604, it will be scraped and removed by the scraping blade 604. The scraping blade 604 is set at an angle, such as... Figure 6 As shown, the scraping force can be increased to avoid jamming. After a period of time, the electromagnet 610 will automatically stop running, thereby achieving a cycle of ice point cleaning. There is a certain small gap between the scraping blade 604 and the outer surface of the rotating housing 3 to prevent the scraping blade 604 from scratching the surface of the rotating housing 3 during daily use.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
