Description

Technical Field

[0001] The utility model relates to the technical field of water heater filtration, in particular to a multi-stage filtration device for a dual-heat-source heat pump water heater. Background Art

[0002] A heat pump water heater is a device that uses the heat pump principle to heat hot water. It achieves heating by extracting low-temperature heat energy from the environment (such as air, ground or water) and transferring it to hot water. Compared with traditional electric water heaters, heat pump water heaters are more energy-efficient because they can obtain more heat energy with less electricity consumption. In order to avoid the formation of scale in the water heater, the heated water needs to be pre-treated. Traditional water filtration is mainly carried out through filters and activated carbon. Activated carbon may be displaced or tilted during use, resulting in a decrease in its filtration effect. Secondly, maintenance and cleaning of activated carbon columns are cumbersome, which increases replacement time and labor costs. In response to the above problems, the inventors proposed a multi-stage filtration device for dual-heat source heat pump water heaters to solve the above problems. Utility Model Content

[0040] Working principle: When the activated carbon column in the water heater needs to be replaced, remove the screws on the top cover of the second filter chamber 2 and open the top cover, then lift the lifting frame 603 as above, and the lifting frame 603 moves upward under the guidance of the slide rail 601 through the lifting block 602, and then manually fit the bottom of the activated carbon column with the lifting frame 603 and move it to the side of the fitting plate 703. After the activated carbon column is fitted with the fitting plate 703, continue to push the activated carbon column to move. At this time, the fitting plate 703 drives the fixed block 707 and the connecting column 711 to move synchronously through the insertion rod 702, and the fixed block 707 drives the elastic card plate 708 to move from the first slot in the limit plate 709 to the second slot, and the elastic card plate 708 is limited by the second slot, and the connecting column 711 moves in the cylindrical frame 710 to the No. 1 reset spring. 712 is squeezed, and the insertion rod 702 moves while driving the folding rod 704 to fold through the connecting rod 705 to clamp and fix the activated carbon column using the clamping plate 706. When the activated carbon column needs to be replaced, manually press the fixed column 802, and the fixed column 802 drives the moving block 803 to move and squeezes the No. 2 return spring 805. While moving, the moving block 803 drives the two sliders 807 away from each other through the synchronization rod 804. The slider 807 moves through the bolt 808 to push the elastic card 708 out of the second slot of the limit plate 709. Under the action of the No. 1 return spring 712, the insertion rod 702 and the fitting plate 703 are reset. When the insertion rod 702 moves, it drives the folding rod 704 to reset, so that the clamping plate 706 is separated from the activated carbon column, thereby taking out the activated carbon column.
