Description

Technical Field

[0001] The invention relates to the technical field of water heating devices, and in particular to a cold and hot water fully mixing device. Background Art

[0002] Most of the water outlets on the market are faucets, showers and control valves. Showers are almost one of the essential bathroom appliances in every home. One of the components of a shower is a hot and cold water mixing mechanism. The hot and cold water are mixed and then discharged to obtain mixed water of a specific temperature, so as to achieve the effect of mixed water output at a specified temperature.

[0003] The invention patent with authorization announcement number CN116412532B discloses a hot and cold water circulation device, including a water heater, wherein the water heater has a heat-conducting ring plate, a heater, a water inlet pipe and a heat-conducting pipe, wherein the heat-conducting pipe is coiled on the heat-conducting ring plate, and further includes: a water storage mechanism, including a water tank installed on the water heater and located in the heat-conducting ring plate, wherein the top of the water tank is connected to a steam pipe, and the water outlet end of the heat-conducting pipe is connected to a hot water pipe, and the inner wall of the hot water pipe is hollow.

[0004] However, the above-mentioned hot and cold water circulation device still has some shortcomings in actual use: the scraper is moved vertically by a driving member to scrape the dirt on the water tank, a wire groove is provided on the top of the scraper for accommodating the dirt, and a driving member for driving the wire groove to move is installed on the water tank. The bottom plate can be installed in the water tank by bolting. After the bottom plate is removed, the bolts on the connecting plate are screwed in to remove the scraper, which is convenient for cleaning the dirt in the wire groove. However, the dirt will enter only when the scraper moves upward, and moving downward will not achieve the purpose of collecting the dirt. In addition, the accumulation of dirt to a certain extent can easily cause blockage, and the bottom plate needs to be removed to clean the dirt, which is very troublesome and complicated.

[0047] In this embodiment, when the motor 2 6 drives the mixing shaft 19 to rotate clockwise, the main scraper 20 will clean the scale on the outer wall of the filter plate 14 and then fall into the water below to avoid clogging of the filter plate 14. At the same time, when the first gear 21 is engaged with the annular rack 22, the second shaft 27 will be driven to rotate through the chain 1 24.

[0051] In the present embodiment, initially, the sliding arc plate 30 is pressed against the limit stop rod 29 due to the elastic force of the third shaft rod 36, so that when the mixing frame 18 is out of the water, the filter plate 26 will salvage some scale, and when the mixing frame 18 is in close contact with the collecting cover 34, the opening and closing stop rod 45 is resisted, thereby opening the door panel 54, and the transmission shaft rod 38 will drive the transmission gear 3 40 to rotate, thereby causing the transmission gear 7 57 to drive the threaded rod 41 to rotate, so that the scale collecting plate 33 scrapes off the scale impurities on the outer surface of the filter plate 26.

[0052] Among them, the scale collection mechanism 606 includes a first bevel gear 48, a second bevel gear 49, a chain five 51 and two transmission gears four 50, the first bevel gear 48 is fixedly connected to the threaded rod 41, the second bevel gear 49 is meshed with the outer wall of the first bevel gear 48, the second bevel gear 49 is fixedly connected to one of the transmission gears four 50, the chain five 51 is sleeved on the outer walls of the two transmission gears four 50, the two transmission gears four 50 are both rotatably connected to the dirt treatment chamber 35, the inner wall of the dirt treatment chamber 35 is rotatably connected to two fifth shafts 52, the outer walls of the two fifth shafts 52 are sleeved with conveyor belts 42, the outer wall of the conveyor belt 42 is fixedly connected to a plurality of flexible scrapers 43, one of the fifth shafts 52 is fixedly connected to the transmission gear four 50.

[0053] Among them, the opening and closing discharge mechanism 707 includes a door panel 54, an auger 15 and a motor 26. The door panel 54 is slidingly connected to the inner wall of the mixing shaft 19. A number of springs 453 are fixedly connected between the door panel 54 and the mixing shaft 19. Two opening and closing levers 45 are fixedly connected to the outer wall of the door panel 54. The auger 15 is arranged inside the mixing shaft 19. The output shaft of the motor 26 is fixedly connected to the third shaft 36. The third shaft 36 is fixedly connected to the auger 15. The motor 26 is fixedly connected to the scale collection frame 7.

[0054] In this embodiment, the scale collecting plate 33 is set between the two limit stops 29, and can move from the top to the bottom. Then, since the first bevel gear 48 drives the second bevel gear 49 to rotate, the second bevel gear 49 drives the two fifth shafts 52 to rotate through the transmission gear four 50 and the chain five 51, so that when the scale collecting plate 33 moves to the bottom, it will briefly contact the conveyor belt 42, so that the conveyor belt 42 can scrape the scale on the scale collecting plate 33, and then contact the outer wall of the auger 15 below so that the scale is transmitted out by the auger 15. The rotating motor 32 moves to the second limit stop rod 29 and can be reversed. At this time, the spring three 46 supports the sliding arc plate 30 to reset until the mixing frame 18 is separated from the collection cover 34 at the first limit stop rod 29, and the scale collecting plate 33 moves back to the top of the collection cover 34.

[0055] The specific working principle and method of use of the present invention are explained in detail below: when in use, cold water flows into the mixing chamber 5 through the cold water pipe 4, and hot water flows into the hot water pipe 12 after being heated by the heating mechanism 10. Since the density of hot water is less than that of cold water, the connection between the regulating valve 2 13 and the mixing chamber 5 is lower than the cold water pipe 4, so that the hot water and the cold water can be automatically mixed. At the same time, the motor 2 6 rotates back and forth, driving the mixing shaft 19 to rotate, and the sliding arc plate 30 only rotates between the two limit bars 29. The mixed water will enter through the filter plate 1 14 and flow through the chamber 9 and then flow out through the outlet pipe 8. The water level is set lower than the mixing shaft 19. The filter plate 14 is used to block impurities such as scale.

[0056] like Figure 2 As shown, when the motor 2 6 drives the mixing shaft 19 to rotate clockwise, the main scraper 20 will clean the scale on the outer wall of the filter plate 14 and then fall into the water below to avoid clogging of the filter plate 14. At the same time, when the first gear 21 is engaged with the annular rack 22, the second shaft 27 will be driven to rotate through the chain 1 24. The three second shafts 27 rotate together through the chain 2 28 and the transmission gear 1 25, so that the mixing effect is further enhanced.

[0057] Initially, the sliding arc plate 30 is tightly against the limit stop rod 29 due to the elastic force of the third shaft rod 36, so that when the mixing frame 18 is out of the water, the filter plate 26 will salvage some scale. When the mixing frame 18 is tightly against the collecting cover 34, the opening and closing stop rod 45 is resisted, thereby opening the door plate 54. The transmission shaft rod 38 will drive the transmission gear 3 40 to rotate, thereby causing the transmission gear 7 57 to drive the threaded rod 41 to rotate, so that the scale collecting plate 33 scrapes off the scale impurities on the outer surface of the filter plate 26.

[0058] Set between the two limit stops 29, the scale collecting plate 33 can move from the top to the bottom, and then because the first bevel gear 48 drives the second bevel gear 49 to rotate, the second bevel gear 49 drives the two fifth shafts 52 to rotate through the transmission gear four 50 and the chain five 51, so that when the scale collecting plate 33 moves to the bottom, it will briefly contact the conveyor belt 42, so that the conveyor belt 42 can scrape the scale on the scale collecting plate 33, and then contact the outer wall of the auger 15 below so that the scale is transmitted out by the auger 15, and the rotating motor 32 moves to the second limit stop rod 29 to reverse. At this time, the spring three 46 supports the sliding arc plate 30 to reset, until the mixing frame 18 is separated from the collection cover 34 at the first limit stop rod 29, and the scale collecting plate 33 moves back to the top of the collection cover 34.

[0059] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
