Technical Field

[0001] The utility model relates to the technical field of water heaters, and more specifically, to an air - energy water heater with a self - cleaning function for the water tank. Background Art

[0002] An air - energy water heater absorbs heat from the air, compresses and boosts the temperature after being compressed by a compressor, and then transfers the heat to the water in the water tank through a heat exchanger to achieve the purpose of heating the water temperature. For example, an air - energy water heater convenient for heat absorption with the patent publication number CN209605401U includes an air - energy water heater housing. The inner wall of the air - energy water heater housing is fixedly connected with a large - blade suction fan. The bottom of the large - blade suction fan is fixedly connected with an air - energy evaporator. The surface of the air - energy evaporator is fixedly connected with the inner wall of the air - energy water heater housing. One side of the inner wall of the air - energy water heater housing close to the air - energy evaporator is fixedly connected with an air - energy compressor. The bottom of the air - energy compressor is fixedly connected with an air - energy condenser. The side of the air - energy water heater housing is fixedly connected with a heat transfer pipe. This air - energy water heater convenient for heat absorption achieves the effect of convenient heat absorption for the air - energy water heater by setting a funnel heat - collecting cover, a heat - collecting layer, a solar heat - absorbing plate, a heat - collecting pipe, a multi - directional heat - collecting cover, a C - shaped groove, and a heat - absorbing block.

[0003] During the use of the existing air - energy water heater, the water in the water tank will continuously circulate and evaporate. As the water evaporates, the mineral concentration in the water gradually increases, further promoting the formation of water scale. Therefore, users need to clean the water tank regularly. Thus, we make improvements and propose an air - energy water heater with a self - cleaning function for the water tank. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an air - energy water heater with a self - cleaning function for the water tank, which can effectively solve the problem that too much water scale accumulates inside the water tank after long - term use.

[0005] To achieve the above - mentioned purpose, the technical solution adopted by the utility model is as follows:

[0006] An air - energy water heater with a self - cleaning function for the water tank includes an external unit and a water tank body. A copper pipe for connecting with the external unit is installed at the upper end of the water tank body. A coil is fixedly installed at the lower end of the copper pipe. A driving component is fixedly installed at the top of the water tank body. The lower end of the driving component is connected with a cleaning component for cleaning the water tank body. A sewage discharge pipe for discharging impurities is fixedly installed at the bottom of the water tank body. A control valve is arranged outside the sewage discharge pipe.

[0007] Preferably, a water inlet pipe for supplementing cold water is respectively arranged on one side of the water tank body, and a water outlet pipe for discharging hot water is arranged above the water inlet pipe. A temperature sensing probe for detecting temperature and a magnesium rod seat for installing a magnesium rod are respectively installed on the inner wall of the water tank body.

[0008] Preferably, the cleaning component includes a rotating shaft rotatably installed at the upper end of the water tank body. A connecting plate is fixedly installed at the bottom of the rotating shaft, and arc-shaped scraping plates for removing water scale are respectively installed at both ends of the connecting plate.

[0009] Preferably, movable grooves are respectively formed at both ends of the connecting plate. A movable seat is fixedly installed at the upper end of the arc-shaped scraping plate, and the movable seat is movably installed inside the movable groove. An elastic block is installed inside the movable groove.

[0010] Preferably, a guiding push plate is fixedly installed at the lower end of each arc-shaped scraping plate. A guiding groove is arranged at the bottom of the water tank body, and the bottom of the guiding push plate is attached to the guiding groove.

[0011] Preferably, an extension plate is fixedly installed between the two guiding push plates. An installation column is fixedly installed at the bottom of the extension plate, and a plurality of knocking blocks are fixedly installed on the column body of the installation column. The knocking blocks are located inside the sewage pipe.

[0012] Preferably, the driving component includes a fixed cover fixedly installed at the upper end of the water tank body. A driven shaft and a driving shaft are respectively rotatably installed inside the fixed cover. The driven shaft is fixedly connected to the rotating shaft. A driving motor is fixedly installed at the upper end of the fixed cover, and the output end of the driving motor is fixedly connected to the driving shaft. A semi-gear is fixedly installed on the shaft body of the driving shaft, and a mating gear is fixedly installed on the shaft body of the driven shaft. The mating gear meshes with the semi-gear.

[0013] Preferably, an extension cover is arranged on one side of the upper surface of the fixed cover. A connecting frame is fixedly installed at the upper end of the driven shaft, and a reset coil spring is fixedly installed inside the connecting frame. The outer side of the reset coil spring is fixedly connected to the extension cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) When the rotating shaft rotates, it will drive the connecting plate to rotate, and the arc-shaped scraping plates will scrape the water scale generated on the inner wall of the water tank body. In order to avoid damage to the arc-shaped scraping plates, an elastic block is installed inside the movable groove, so that the arc-shaped scraping plates can move within a certain range when contacting harder water scale, and the harder water scale will fall off through continuous cleaning. When the water scale falls off, it will fall into the guiding groove, so there is no need to avoid the formation of large pieces of water scale. Furthermore, through self-cleaning, users do not need to manually clean it themselves.

[0016] The guiding push plate will also rotate accordingly, thereby driving the scale on the surface of the guiding groove into the sewage discharge pipe. Moreover, by using the extension plate to connect the mounting post and the guiding push plate, several knocking blocks on the column body of the mounting post can further knock the scale that has fallen into the sewage discharge pipe, causing the agglomerated scale to split and preventing subsequent control valves from being blocked when discharging impurities.

[0017] (2) By starting the driving motor to drive the rotation of the driving shaft, when the driving shaft rotates, the semi-gear will engage with the mating gear, causing the mating gear to rotate, and then driving the cleaning assembly to perform cleaning. During the cleaning process, since structures such as a magnesium rod and a temperature sensing probe need to be installed inside the water tank body, in order to prevent the cleaning assembly from interfering with these structures, the rotation angle of the mating gear is limited by the semi-gear, thereby controlling the cleaning range of the cleaning assembly. And by the semi-gear missing the mating gear, with the cooperation between the reset coil spring and the connecting frame, the connecting frame and the driven shaft below it can be reset, not only enabling reverse cleaning but also being used for the next cleaning. Through the above structure, the present application can ensure that the water tank body is cleaned without affecting the internal structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 7 shown, an air energy water heater with a self-cleaning function for the water tank includes an outdoor unit 8 and a water tank body 1. A copper pipe 3 for connecting to the outdoor unit 8 is installed at the upper end of the water tank body 1. A coil 301 is fixedly installed at the lower end of the copper pipe 3. A driving assembly 2 is fixedly installed at the top of the water tank body 1. A cleaning assembly 7 for cleaning the water tank body 1 is connected to the lower end of the driving assembly 2. A drain pipe 10 for discharging impurities is fixedly installed at the bottom of the water tank body 1. A control valve 11 is arranged outside the drain pipe 10.

[0028] In this embodiment, an inlet pipe 5 for supplementing cold water is respectively arranged on one side of the water tank body 1. An outlet pipe 4 for discharging hot water is arranged above the inlet pipe 5. A temperature sensor probe 12 for detecting temperature and a magnesium rod seat 6 for installing a magnesium rod are respectively installed on the inner wall of the water tank body 1.

[0029] In this embodiment, the cleaning assembly 7 includes a rotating shaft 701. The rotating shaft 701 is rotatably installed at the upper end of the water tank body 1. A connecting plate 702 is fixedly installed at the bottom of the rotating shaft 701. Arc-shaped shoveling plates 703 for removing water scale are respectively installed at both ends of the connecting plate 702.

[0030] Among them, activity grooves 7021 are respectively opened at both ends of the connecting plate 702. An activity seat 7031 is fixedly installed at the upper end of the arc-shaped shoveling plate 703. The activity seat 7031 is movably installed inside the activity groove 7021. An elastic block 7022 is installed inside the activity groove 7021.

[0031] In this embodiment, a guiding push plate 704 is fixedly installed at the lower end of each arc-shaped shovel plate 703, a guiding groove 9 is arranged at the bottom of the water tank body 1, and the bottom of the guiding push plate 704 is attached to the guiding groove 9;

[0032] An extension plate 705 is fixedly installed between the two guiding push plates 704, an installation column 706 is fixedly installed at the bottom of the extension plate 705, and a number of knocking blocks 707 are fixedly installed on the column body of the installation column 706. The knocking blocks 707 are located inside the sewage pipe 10.

[0033] When the rotating shaft 701 rotates, it will drive the connecting plate 702 to rotate, and the arc-shaped shovel plate 703 will remove the scale generated on the inner wall of the water tank body 1. In order to avoid damage to the arc-shaped shovel plate 703, an elastic block 7022 is installed inside the movable groove 7021, which can make the arc-shaped shovel plate 703 move within a certain range when contacting harder scale, and the harder scale will fall off through continuous cleaning. When the scale falls off, it will fall into the guiding groove 9;

[0034] The guiding push plate 704 will also rotate accordingly, so as to introduce the scale on the surface of the guiding groove 9 into the sewage pipe 10. And by using the extension plate 705 to connect the installation column 706 and the guiding push plate 704, a number of knocking blocks 707 on the column body of the installation column 706 can further knock the scale falling into the sewage pipe 10, so that the agglomerated scale is split to avoid blockage of the subsequent control valve 11 when discharging impurities.

[0035] In this embodiment, the driving assembly 2 includes a fixed cover 201. The fixed cover 201 is fixedly installed at the upper end of the water tank body 1. A driven shaft 202 and a driving shaft 203 are respectively rotatably installed inside the fixed cover 201. The driven shaft 202 is fixedly connected to the rotating shaft 701. A driving motor 204 is fixedly installed at the upper end of the fixed cover 201. The output end of the driving motor 204 is fixedly connected to the driving shaft 203. A semi-gear 2031 is fixedly installed on the shaft body of the driving shaft 203, and a mating gear 2021 is fixedly installed on the shaft body of the driven shaft 202. The mating gear 2021 meshes with the semi-gear 2031.

[0036] Wherein, an extension cover 205 is arranged on one side of the upper surface of the fixed cover 201. A connecting frame 2022 is fixedly installed at the upper end of the driven shaft 202. A return spring 2023 is fixedly installed inside the connecting frame 2022. The outer side of the return spring 2023 is fixedly connected to the extension cover 205.

[0037] By starting the drive motor 204 to drive the rotation of the drive shaft 203, when the drive shaft 203 rotates, the half gear 2031 will engage with the mating gear 2021, causing the mating gear 2021 to rotate, and then driving the cleaning assembly 7 to perform cleaning. During the cleaning process, since structures such as a magnesium rod and a temperature sensing probe 12 need to be installed inside the water tank body 1, in order to prevent the cleaning assembly 7 from interfering with its structure, the rotation angle of the mating gear 2021 is limited by the half gear 2031, so that the cleaning range of the cleaning assembly 7 is controlled. And by the half gear 2031 missing the mating gear 2021, with the cooperation between the return spring 2023 and the connecting frame 2022, the connecting frame 2022 and the driven shaft 202 below it can be reset, not only can reverse cleaning be carried out, but also it can be used for the next cleaning. Through the above structure, the present application can ensure that the water tank body 1 is cleaned without affecting the internal structure.

[0038] The working principle of an air - energy water heater with a self - cleaning function for the water tank:

[0039] During use, by starting the drive motor 204 to drive the rotation of the drive shaft 203, when the drive shaft 203 rotates, the half gear 2031 will engage with the mating gear 2021, causing the mating gear 2021 to rotate, making the rotating shaft 701 rotate, then driving the connecting plate 702 to rotate, and causing the arc - shaped scraping plate 703 to scrape the scale generated on the inner wall of the water tank body 1. Among them, in order to prevent the arc - shaped scraping plate 703 from being damaged, an elastic block 7022 is installed inside the movable groove 7021, which can make the arc - shaped scraping plate 703 move within a certain range when contacting harder scale, and through continuous cleaning, the harder scale will fall off. When the scale falls off, it will drop into the guiding groove 9;

[0040] After that, the guiding push plate 704 will also rotate accordingly, thereby driving the scale on the surface of the guiding groove 9 into the sewage pipe 10. And by using the extension plate 705 to connect the mounting column 706 and the guiding push plate 704, several knocking blocks 707 on the column body of the mounting column 706 can further knock the scale falling into the sewage pipe 10, splitting the agglomerated scale to prevent subsequent clogging of the control valve 11 when discharging impurities;

[0041] During the cleaning process, the rotation angle of the mating gear 2021 is limited by the half gear 2031, so that the cleaning range of the cleaning assembly 7 is controlled. And by the half gear 2031 missing the mating gear 2021, with the cooperation between the return spring 2023 and the connecting frame 2022, the connecting frame 2022 and the driven shaft 202 below it can be reset, not only can reverse cleaning be carried out, but also damage to the internal structure can be avoided.

[0042] Obviously, the above embodiments of the present utility are merely examples for clearly illustrating the present utility, rather than limitations on the implementation manners of the present utility. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is impossible to enumerate all implementation manners here. Any obvious changes or alterations derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
