Description

Technical Field

[0001] This application relates to the technical field of refrigeration, and in particular to a water chiller that is convenient for maintenance. Background Art

[0002] A water chiller is a refrigeration device that is widely used in various occasions that require refrigeration. It mainly consists of main components such as a water pump, a water tank, an evaporator, and a condenser, and reduces the temperature of an object through the circulation of a refrigerant.

[0003] After the water tank has been used for a certain number of years, dirt usually adheres to its inner wall, so it needs to be cleaned. However, most water tanks are integral and cannot be disassembled. Therefore, cleaning can only be achieved through its water inlet and outlet. The cleaning process is relatively inconvenient and there may be some blind areas and dead corners that cannot be cleaned, which has obvious deficiencies. Summary of the Invention

[0004] In order to improve the problem of inconvenient cleaning of dirt in the water tank and poor cleaning effect, this application provides a water chiller that is convenient for maintenance.

[0005] A water chiller that is convenient for maintenance provided by this application adopts the following technical solutions:

[0006] A water chiller that is convenient for maintenance includes a water tank with a hollow interior, a dirt scraping component and a flushing component arranged in the water tank. The dirt scraping component includes an annular scraper that is vertically slidably arranged in the water tank and is in close contact with its inner wall. An installation bracket is arranged at the top of the water tank. A handle is rotatably arranged on the installation bracket. A wire winding wheel is arranged on the handle. An L-shaped support arm is arranged at the top of the annular scraper. A lifting pull rod is vertically slidably penetrated through the bracket. A top block for propping up the top wall of the annular scraper is arranged at the bottom end of the lifting pull rod. A pushing spring is propped between the top block and the support arm and is sleeved on the lifting pull rod. A pulling wire is tied to the top end of the lifting pull rod. The pulling wire slides out from the top wall of the water tank and is wound around the wire winding wheel.

[0007] By adopting the above technical solutions, when cleaning is required, the worker manually rotates the handle so that the wire winding wheel winds up the pulling wire. The pulling wire pulls the lifting pull rod to move upward. The lifting pull rod drives the top block to cooperate with the support arm to squeeze the pushing spring. When the pushing spring is compressed to a certain extent, the worker releases the handle, and the deformation force of the pushing spring is suddenly released. The pulling wire wound around the wire winding wheel is pulled out again, and at the same time, the top block is pushed downward to impact the annular scraper. The annular scraper moves downward a small distance under the impact. In this way, the annular scraper can scrape off the dirt on the vertical inner wall of the water tank. Repeat the above operation process until the annular scraper moves to the lowest point of the vertical inner wall. Then, cooperate with the flushing component to wash away the scraped dirt. The cleaning process is relatively simple and improves the cleaning quality.

[0008] Optionally, vertical friction strips are embedded on the inner wall of the water tank. A receiving groove is formed on the circumferential outer wall of the ring scraper at a position opposite to the top block. A friction abutting strip for abutting against the friction strip is hinged in the receiving groove. A magnetic block for magnetically attracting the friction abutting strip is arranged on the top block. An adjustment groove for the horizontal movement of the lifting pull rod is formed on the support arm in the radial direction of the water tank. An adjustment wheel is rotatably penetrated through the top wall of the water tank above the support arm. The pull wire slides through the adjustment wheel.

[0009] By adopting the above technical solution, during the process of the ring scraper descending to remove dirt, when the adjustment wheel rotates to the position where the pull wire is closest to the axis of the water tank, at this time, during the entire lifting process of the top block driving the magnetic block, the magnetic attraction between the magnetic block and the friction abutting strip is too small, and the friction abutting strip always abuts against the friction strip. In this way, when the worker manually rotates the handle to wind up the pull wire, the pushing compression spring can be compressed to a large extent while the ring scraper remains stationary due to the friction between the friction abutting strip and the friction strip. The worker manually rotates the adjustment wheel to make the pull wire rotate to the position farthest from the axis of the water tank. At this time, the top block drives the magnetic block to approach the friction abutting strip. At the same time, during the entire lifting process of the magnetic block, a large magnetic attraction can always be maintained between it and the friction abutting strip. In this way, the friction abutting strip rotates and disengages from the contact with the friction strip. At this time, by rotating the handle, the worker can lift the ring scraper to a high position to achieve reset.

[0010] Optionally, a ring-shaped storage cavity is formed by upward protrusion at a position near the edge of the top of the water tank. When the ring scraper is not in use, it is located in the storage cavity.

[0011] By adopting the above technical solution, the storage cavity can protect the ring scraper, the support arm, etc., thereby reducing the possibility of being contaminated by dirt and ensuring the cleanliness of the scraping component itself.

[0012] Optionally, a scraper is rotatably arranged in the ring scraper flush with its lowest part. A transmission rod coaxial with it is vertically rotatably arranged in the water tank. A lifting groove is vertically formed on the transmission rod. The scraper extends into the lifting groove and is slidably matched with it. The top end of the transmission rod rotatably penetrates through the top wall of the water tank and is connected to the bottom end of the handle.

[0013] By adopting the above technical solution, when the ring scraper moves downward, it can drive the scraper to move downward synchronously. And when the worker rotates the handle, the handle can drive the scraper to rotate through the transmission rod. When the scraper descends to abut against the inner bottom wall of the water tank, the rotation of the scraper can scrape the dirt on the inner bottom wall of the water tank, further improving the comprehensiveness of dirt removal in the water tank.

[0014] Optionally, the flushing assembly includes a water diversion chamber which is arranged at the top of the water tank and has a hollow interior. The top end of the transmission rod rotates through the water diversion chamber. A connector which is communicated with the interior cavity of the water diversion chamber and used for communicating with a water supply device is reserved on the outer side wall of the water diversion chamber. A screw cap is threadedly connected to the connector. A water passing hole is formed in the transmission rod. The water inlet end of the water passing hole is communicated with the interior cavity of the water diversion chamber, and the water outlet end is communicated with a spray head which is arranged on the transmission rod and is located inside the water tank.

[0015] By adopting the above technical solution, the worker first unscrews the screw cap, and then docks the connector with the water supply device. During the process of scraping dirt, the water supply device supplies clear water into the water diversion chamber. The clear water flows through the water passing hole and then is sprayed out by the spray head, thereby flushing the dirt on the vertical inner wall and the inner bottom wall of the water tank.

[0016] Optionally, the handle is slidably matched with the wire winding wheel, and the bottom end of the handle is inserted and matched with the top end of the transmission rod.

[0017] By adopting the above technical solution, the handle and the transmission rod are separately arranged, so that during the process of the ring scraper descending, the handle and the transmission rod are in a disengaged contact state. When the ring scraper descends to the lowest position, the handle is inserted and matched with the transmission rod again, thereby reducing the bearing strength on the worker's hand during the cleaning process.

[0018] Optionally, a plurality of spray heads are circumferentially arranged on the transmission rod, and all the spray heads are communicated with the water passing hole.

[0019] By adopting the above technical solution, the plurality of spray heads greatly increase the flushing area, which is beneficial to improving the flushing quality of dirt.

[0020] Optionally, the insertion and matching part between the bottom end of the handle and the top end of the transmission rod is in the shape of a flat key.

[0021] By adopting the above technical solution, the flat-key-shaped insertion and matching ensures that the handle can drive the transmission rod to rotate synchronously, avoiding the phenomenon of slipping.

[0022] In summary, the present application includes at least the following beneficial technical effects:

[0023] 1. When cleaning is required, the worker manually rotates the handle to make the wire winding wheel wind up the wire rope. The wire rope pulls the lifting rod upward. The lifting rod drives the top block to cooperate with the support arm to squeeze the push top compression spring. When the push top compression spring is compressed to a certain extent, the worker releases the handle. The deformation force of the compression spring is suddenly released, and the wire rope wound on the wire winding wheel is pulled out again. At the same time, the top block is pushed downward to impact the ring scraper, and the ring scraper moves downward a small distance under the impact. In this way, the ring scraper can scrape off the dirt on the vertical inner wall of the water tank. Repeat the above operation process until the ring scraper moves to the lowest position of the vertical inner wall. Thereafter, cooperate with the flushing assembly to flush away the scraped dirt. The cleaning process is relatively simple and improves the cleaning quality;

[0024] 2. During the process of the annular scraping knife descending to remove dirt, the positioning wheel rotates to the position where the wire is closest to the axis of the water tank. At this time, during the entire lifting process of the top block driving the magnet, the magnetic attraction between the magnet and the friction contact strip is too small, and the friction contact strip always presses tightly against the friction strip. In this way, when the worker manually rotates the handle to wind up the wire, the pushing spring can be compressed to a large extent, and the annular scraping knife remains stationary through the friction between the friction contact strip and the friction strip. When the worker manually rotates the positioning wheel to make the wire rotate to the position farthest from the axis of the water tank, the top block drives the magnet close to the friction contact strip. At the same time, during the entire lifting process of the magnet, a large magnetic attraction can always be maintained between it and the friction contact strip. In this way, the friction contact strip rotates and disengages from the friction strip. At this time, when the worker rotates the handle, the annular scraping knife can be lifted upward to achieve reset;

[0025] 3. When the annular scraping knife moves downward, it can drive the scraping plate to move downward synchronously. And when the worker rotates the handle, the handle can drive the scraping plate to rotate through the transmission rod. When the scraping plate descends to contact the inner bottom wall of the water tank, the rotation of the scraping plate can scrape the dirt on the inner bottom wall of the water tank, further improving the comprehensiveness of dirt removal in the water tank.

Detailed Embodiments

[0031] The following will further describe the present application in detail with reference to the attached Figures 1-4 drawings.

[0032] An embodiment of the present application discloses a water chiller that is convenient for maintenance.

[0033] Reference Figure 1 , the chiller that is convenient for maintenance includes a water tank 1 with a hollow interior and a cylindrical shape. Since dirt will adhere to both the vertical inner wall and the inner bottom wall of the water tank 1 after long-term use, in order to facilitate the cleaning of dirt, a dirt scraping component and a flushing component are arranged on the water tank 1.

[0034] Reference Figure 2 and Figure 3 , the dirt scraping component includes a mounting bracket 22 welded to the top of the water tank 1. A wire winding wheel 24 is rotatably arranged on the mounting bracket 22, and a handle 23 is coaxially and slidably penetrated through the wire winding wheel 24.

[0035] Reference Figure 2 and Figure 3 , a hydrophilic aluminum foil is adhered to the inner wall of the water tank 1, and a ring scraper 21 that is in close contact with it is vertically slidably fitted. Two L-shaped support arms 25 are welded to the top of the ring scraper 21. The two support arms 25 are symmetrically distributed about the axis of the water tank 1. Two pull wires 29 are wound around the wire winding wheel 24, and one pull wire 29 corresponds to one support arm 25.

[0036] Reference Figure 2 and Figure 3 , a positioning groove 251 is radially opened on the support arm 25 relative to the water tank 1. An elevating pull rod 26 is horizontally slidably fitted and vertically liftably fitted in the positioning groove 251. The top end of the elevating pull rod 26 is tied to the corresponding pull wire 29.

[0037] A top block 27 for hitting the top wall of the ring scraper 21 is integrally formed at the bottom end of the elevating pull rod 26. A push spring 28 is propped between the top block 27 and the support arm 25. The push spring 28 is sleeved on the elevating pull rod 26, and a magnetic block 5 is embedded at the bottom of the top block 27.

[0038] Reference Figure 2 and Figure 3 , a positioning wheel 6 is rotatably penetrated through the top wall of the water tank 1 at a position above the support arm 25. The pull wire 29 slides through the positioning wheel 6, and there is a distance between the position where the pull wire 29 passes through the positioning wheel 6 and the axis of the positioning wheel 6.

[0039] Reference Figure 2 and Figure 3 , vertical friction strips 3 are embedded on the inner wall of the water tank 1. A receiving groove 211 is opened on the circumferential outer side wall of the ring scraper 21 at a position opposite to the top block 27. A friction abutting strip 4 for abutting against the friction strip 3 is hinged in the receiving groove 211, and the friction abutting strip 4 is magnetically attracted to the magnetic block 5.

[0040] Reference Figure 2 and Figure 3, when cleaning is required, the worker first rotates the position adjustment wheel 6 to adjust the wire 29 close to the axis of the water tank 1. Then, manually rotate the handle 23 to wind up the wire 29 by the wire winding wheel 24. The wire 29 pulls the lifting rod 26 upward, and the lifting rod 26 drives the top block 27 to cooperate with the support arm 25 to squeeze the pushing spring 28.

[0041] At this time, since the distance between the magnetic block 5 and the friction contact strip 4 is relatively far, the magnetic attraction between the magnetic block 5 and the friction contact strip 4 is very small, almost non-existent. Therefore, during the lifting and lowering process of the lifting rod 26, the friction contact strip 4 always presses tightly against the friction strip 3, and the frictional force between the friction contact strip 4 and the friction strip 3 is relatively large. During the process of the pushing spring 28 being compressed and deformed, the ring scraper 21 remains stationary.

[0042] When the pushing spring 28 is compressed to a certain extent, the worker releases the handle 23, and the deformation force of the spring is instantly released. The wire 29 wound around the wire winding wheel 24 is pulled out again. At the same time, the top block 27 is pushed downward to impact the ring scraper 21. The friction between the friction contact strip 4 and the friction strip 3 does not hinder the downward movement of the ring scraper 21. Therefore, the ring scraper 21 moves downward a small distance under the impact.

[0043] Repeat the above operation process until the ring scraper 21 moves to the lowest position of the vertical inner wall, so that the ring scraper 21 can scrape off the dirt on the vertical inner wall of the water tank 1.

[0044] Refer to Figure 2 、 Figure 3 and Figure 4 , a scraper 8 is rotatably arranged in the ring scraper 21 at a level flush with its lowest point. A transmission rod 9 is coaxially rotatably arranged in the water tank 1. A lifting groove 91 is vertically opened on the transmission rod 9. The scraper 8 extends into the lifting groove 91 and is slidably matched with it. The top end of the transmission rod 9 rotatably passes through the top wall of the water tank 1 and is inserted and matched with the bottom end of the handle 23. The insertion and matching part between the bottom end of the handle 23 and the top end of the transmission rod 9 is in the shape of a flat key.

[0045] Refer to Figure 2 、 Figure 3 and Figure 4 , during the downward movement of the ring scraper 21, the scraper 8 is driven to descend synchronously, and the handle 23 and the transmission rod 9 are in a disengaged state. When the scraper 8 descends to closely adhere to the inner bottom wall of the water tank 1, the worker manually presses the handle 23 downward to make the handle 23 and the transmission rod 9 inserted and matched.

[0046] After that, when the worker manually rotates the handle 23 again, the transmission rod 9 will drive the scraper 8 to rotate synchronously, so that the scraper 8 can scrape off the dirt on the inner bottom wall of the water tank 1.

[0047] Refer to Figure 2 、 Figure 3 and Figure 4, after the scraping is completed, the worker manually rotates the position adjusting wheel 6, causing the wire 29 to rotate to the farthest distance from the water tank 1. The lifting rod 26 moves horizontally in the position adjusting groove 251, thereby driving the top block 27 and the magnetic block 5 to move directly above the friction strip 4.

[0048] At this time, the distance between the magnetic block 5 and the friction strip 4 is small. During the lifting process of the top block 27, a large magnetic attraction force can be maintained between the magnetic block 5 and the friction strip 4, causing the friction strip 4 to rotate, disengaging from the contact with the friction bar 3 and pressing tightly against the top wall of the receiving groove 211.

[0049] Refer to Figure 2 , Figure 3 and Figure 4 , when the worker rotates the handle 23 to wind up the wire 29, the wire 29 can drive the ring scraper 21 to move upward to reset. A ring-shaped receiving cavity 7 is formed by the upward protrusion of the position near the edge of the top of the water tank 1. In this way, when the ring scraper 21 is not in use, the ring scraper 21 can be received in the receiving cavity 7.

[0050] Refer to Figure 2 , Figure 3 and Figure 4 , the flushing assembly includes a water diversion chamber 10 welded to the top of the water tank 1 and hollow inside. The top end of the transmission rod 9 rotates through the water diversion chamber 10. A joint 11 communicating with its inner cavity and used to connect with the water supply device is reserved on the outer side wall of the water diversion chamber 10. A screw cap 12 is threadedly connected to the joint 11. The water supply device can be a faucet or a water pump in the prior art, etc.

[0051] Refer to Figure 4 , a water passing hole 92 is provided on the transmission rod 9. The water inlet end of the water passing hole 92 communicates with the inner cavity of the water diversion chamber 10, and the water outlet end is communicated with a spray head 13 threadedly connected to the transmission rod 9 and located inside the water tank 1. A plurality of spray heads 13 are circumferentially distributed on the transmission rod 9.

[0052] Refer to Figure 4 , the worker first unscrews the screw cap 12 in advance, and then docks the joint 11 with the water supply device. During or after the dirt scraping work, the water supply device supplies clean water into the water diversion chamber 10. The clean water flows through the water passing hole 92 and then is sprayed out by each spray head 13, thereby flushing the dirt on the vertical inner wall and the inner bottom wall of the water tank 1.

[0053] The implementation principle of a water chiller that is easy to maintain in the embodiment of the present application is as follows:

[0054] When cleaning is required, the worker first rotates the position adjusting wheel 6 to adjust the wire 29 to be close to the axis of the water tank 1. Then manually rotate the handle 23 to wind up the wire 29 by the wire winding wheel 24. The wire 29 pulls the lifting rod 26 to move upward, and the lifting rod 26 drives the top block 27 to cooperate with the support arm 25 to squeeze the push top compression spring 28.

[0055] At this time, since the distance between the magnetic block 5 and the friction abutting strip 4 is relatively far, the magnetic attraction force between the magnetic block 5 and the friction abutting strip 4 is very small. During the lifting and lowering process of the lifting rod 26, the friction abutting strip 4 always abuts tightly against the friction strip 3, and the frictional force between the friction abutting strip 4 and the friction strip 3 is relatively large. During the process of the pushing spring 28 being compressed and deformed, the ring scraper 21 remains stationary.

[0056] When the pushing spring 28 is compressed to a certain extent, the worker releases the handle 23, and the deformation force of the pushing spring is instantly released. The pulling wire 29 wound around the wire reel 24 is pulled out again, and at the same time, the top block 27 is pushed downward to impact the ring scraper 21. The friction between the friction abutting strip 4 and the friction strip 3 will not hinder the downward movement of the ring scraper 21. Therefore, the ring scraper 21 moves downward a small distance under the impact, and the ring scraper 21 drives the scraper 8 to descend synchronously.

[0057] Repeat the above operation process until the ring scraper 21 moves to the lowest position of the vertical inner wall, so that the ring scraper 21 can scrape off the dirt on the vertical inner wall of the water tank 1.

[0058] After that, the worker manually presses the handle 23 downward so that the handle 23 is inserted and matched with the transmission rod 9. When the worker manually rotates the handle 23 again, the transmission rod 9 will drive the scraper 8 to rotate synchronously, so that the scraper 8 can scrape off the dirt on the inner bottom wall of the water tank 1.

[0059] At this time, the water supply device supplies clean water to the water diversion chamber 10. The clean water flows through the water holes 92 and then is sprayed out by each spray head 13, thereby flushing away the dirt on the vertical inner wall and the inner bottom wall of the water tank 1.

[0060] The worker manually rotates the positioning wheel 6 again, so that the pulling wire 29 rotates to the farthest distance from the water tank 1. The lifting rod 26 moves horizontally in the positioning groove 251, thereby driving the top block 27 and the magnetic block 5 to move directly above the friction abutting strip 4.

[0061] At this time, the distance between the magnetic block 5 and the friction abutting strip 4 is relatively small. During the lifting and lowering process of the top block 27, a relatively large magnetic attraction force can be maintained between the magnetic block 5 and the friction abutting strip 4, so that the friction abutting strip 4 rotates, disengages from the contact with the friction strip 3 and abuts tightly against the top wall of the receiving groove 211. When the worker rotates the handle 23 to wind up the pulling wire 29, the pulling wire 29 can drive the ring scraper 21 to move upward to reset, so that the ring scraper 21 is re-stored in the storage cavity 7.

[0062] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
