Description

Technical Field

[0001] The invention relates to the technical field of air energy water heaters, and in particular to an air energy integrated machine which is easy to maintain. Background Art

[0002] The air-energy integrated machine is an all-in-one multi-purpose machine that combines a heat pump water heater and an air conditioner. While enjoying energy-saving hot water, you can enjoy air conditioning for free. The heat pump water heater uses the principle of a heat pump to use air as a heat source for hot and cold cycles. The evaporator absorbs heat from the air and introduces it into the water to produce hot water. Therefore, it fundamentally eliminates safety hazards such as leakage of electric water heaters, dry burning, and harmful gases generated during the use of gas water heaters. At the same time, it overcomes the shortcomings of solar water heaters that cannot be used on rainy days and are inconvenient to install. It has the advantages of high safety, high energy saving, long life, and no toxic gas emissions.

[0003] Since the water entering the air energy unit is discharged directly through the tap or water plant, some sewage will settle inside the water tank after long-term use. Therefore, it is necessary to open the sewage outlet regularly for sewage treatment to avoid affecting the cleanliness of the water source heated by the air energy unit.

[0004] During the maintenance and cleaning of sewage in the existing air-energy integrated machine, in order to clean the sewage, it is necessary to remove the water inlet pipe and the water outlet pipe from the pipeline, and then connect the water outlet pipe to the water inlet joint, so that tap water enters the box from the water outlet end of the air-energy heat pump water heater, and the sewage at the bottom of the box is fully flushed to ensure that the sewage can be completely cleaned up. In the process of maintenance, not only do tools need to be used to disassemble and assemble multiple joints back and forth, but the operation is also relatively complicated, which greatly reduces the maintenance efficiency of the device.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-7 The air energy integrated machine shown is easy to maintain, comprising a water tank 1, and an external unit 2 connected to the water tank 1 through a pipeline, the outer wall of the water tank 1 is respectively provided with a hot water outlet 3, a water inlet 4 and a sewage outlet 28, an adjusting block 5 is fixedly connected to the outer wall of the water tank 1, a U-shaped cavity 6 and an L-shaped cavity 7 are respectively opened inside the adjusting block 5, a straight groove 8 is opened inside the adjusting block 5 and located at the bottom of the L-shaped cavity 7 and is connected to the L-shaped cavity 7, an upper circular hole 9 is opened between the inner side of the lateral end of the L-shaped cavity 7 and the inner side of the U-shaped cavity 6, a blocking block 10 is fixedly connected to the inner side of the U-shaped cavity 6 and the L-shaped cavity 7 and at a position corresponding to the upper circular hole 9, and a lower circular hole 11 is opened on the side wall of the blocking block 10;

[0030] The side wall of the adjusting block 5 is fixedly connected with an internal thread sealing sleeve 12, the inner side of the internal thread sealing sleeve 12 is threadedly connected with a screw 13, and the side wall of the screw 13 is arranged through the inner side of the U-shaped cavity 6, and the side wall of the screw 13 is fixedly connected with a rotating rod 14, the inner side of the upper circular hole 9 is provided with a first sealing block 16, the inner side of the lower circular hole 11 is provided with a second sealing block 17, the end of the rotating rod 14 passes through the side wall of the second sealing block 17 and is fixedly connected with an upper pull ring 15, the interior of the first sealing block 16 is provided with a cavity 18, the outer wall of the rotating rod 14 and is located in the cavity A lower pull ring 19 is fixedly connected at 18, a first connecting pipe 20 is fixedly connected between the water inlet 4 and the top of the L-shaped cavity 7, a second connecting pipe 21 is fixedly connected between the hot water outlet 3 and the top of the U-shaped cavity 6, a turntable 25 is fixedly connected to the side wall of the screw 13, a pair of connectors 22 are fixedly connected to the side wall of the adjustment block 5 and are respectively arranged to penetrate the U-shaped cavity 6 and the straight groove 8, and the inner side of the connector 22 is respectively threadedly connected with a drain pipe 23 and a water inlet pipe 24, which are convenient for connecting with an external water source and pipelines through the drain pipe 23 and the water inlet pipe 24;

[0031] When the air energy integrated machine is used for a long time and the sewage discharge inside the water tank 1 needs to be cleaned, first unplug the power supply from the socket, then close the water inlet valve, and then turn the turntable 25 to drive the screw 13 to rotate. Since the screw 13 is threadedly connected with the internal threaded sealing sleeve 12, the screw 13 will be spirally moved outward, and the rotating rod 14 will be driven to move spirally outward. At the same time, the first sealing block 16 and the second sealing block 17 are pushed to slide through the upper pull ring 15 and the lower pull ring 19, so that the first sealing block 16 slides out of the upper circular hole 9, and the connection between the U-shaped cavity 6 and the L-shaped cavity 7 is released. Then, the first sealing block 16 and the second sealing block 17 are driven to move to the lower circular hole 11, so that the L-shaped cavity 7 is disconnected from the water inlet pipe 24, and the U-shaped cavity 6 is disconnected from the drain pipe 23, so as to achieve the connection between the water inlet pipe 24 and the hot water outlet 3;

[0032] Then open the water inlet valve, and then the water source enters the water tank 1 from the top through the water inlet pipe 24, the straight groove 8, the L-shaped cavity 7, the U-shaped cavity 6 and the second connecting pipe 21, so as to flush the inside of the water tank 1. In this process, the connecting rod 31 is driven to rotate outward by the spiral outward movement of the rotating rod 14, which will drive the fixedly connected plug 29 to be gradually screwed out from the sewage outlet 28, and then the sewage inside the water tank 1 is discharged from the sewage outlet 28, and then the sewage is discharged from the sewage pipe 32 through the sewage cavity 30, so that there is no need to use tools to repeatedly disassemble and assemble multiple joints for switching, which saves time and effort and greatly improves the maintenance efficiency of the device. Finally, after the cleaning and maintenance are completed, the turntable 25 is rotated in the reverse direction and the above operation is repeated to switch back.

[0033] In order to improve the sealing effect of sealing the upper circular hole 9 and the lower circular hole 11, both ends of the first sealing block 16 are inclined, and the second sealing block 17 is inclined near the side of the screw 13. The side walls of the first sealing block 16 and the second sealing block 17 are inclined, and the first sealing block 16 and the second sealing block 17 can be rotated in conjunction with the screw 13 to squeeze the first sealing block 16 and the second sealing block 17 into the upper circular hole 9 and the lower circular hole 11 more tightly, thereby improving the sealing effect.

[0034] In order to prevent the rotation of the rotating rod 14 from driving the first sealing block 16 and the second sealing block 17 to rotate, the first sealing block 16 and the second sealing block 17 are fixedly connected to the bottom with a guide block 26, and the bottom of the L-shaped cavity 7 and the U-shaped cavity 6 are provided with a guide groove 27 adapted to the guide block 26, and the guide block 26 is slidably connected to the inner side of the guide groove 27;

[0035] By setting the guide block 26 and the guide groove 27, when the screw 13 drives the first sealing block 16 and the second sealing block 17 to move through the rotating rod 14, the guide block 26 can be driven to slide inside the guide groove 27, thereby guiding the sliding of the first sealing block 16 and the second sealing block 17, preventing the first sealing block 16 and the second sealing block 17 from rotating with the rotating rod 14, causing the first sealing block 16 and the second sealing block 17 inserted into the upper circular hole 9 and the lower circular hole 11 to be rubbed, thereby reducing the service life of the device.

[0036] In order to be able to remove the plug 29 on the sewage outlet 28 while switching the water flow, the plug 29 is threadedly connected to the inner side of the sewage outlet 28, and a sewage chamber 30 is opened inside the adjusting block 5 and next to the sewage outlet 28. The side wall of the rotating rod 14 is fixedly connected to a connecting rod 31 and penetrates the inner side of the sewage chamber 30, and the connecting rod 31 is fixedly connected to the side wall of the plug 29. When the rotating screw 13 drives the rotating rod 14 and the connecting rod 31 to rotate, the fixedly connected plug 29 will be driven to gradually rotate out of the sewage outlet 28, further improving the maintenance efficiency of the air energy integrated machine. On the contrary, the plug 29 will be screwed into the sewage outlet 28 to block the sewage outlet 28. The bottom end of the inner side of the sewage chamber 30 is inclined toward the middle, so that the sewage in the sewage chamber 30 is diverted to the middle and discharged from the sewage pipe 32. The bottom of the adjusting block 5 is fixedly connected to the sewage pipe 32 and is communicated with the sewage chamber 30.

[0037] In order to remind the maintenance personnel when they forget to switch the water flow direction and directly power on, the side wall of the adjustment block 5 is fixedly connected to the fixing frame 33, and the side wall of the fixing frame 33 is provided with a notch 34, through which the sliding of the Z-shaped plate 35 is facilitated, and the Z-shaped plate 35 is slidably connected to the inner side of the fixing frame 33, and a touch sensor 36 is fixedly connected through the side wall of the fixing frame 33, and the side wall of the Z-shaped plate 35 contacts the side wall of the turntable 25, and a spring 38 is fixedly connected between the side wall of the adjustment block 5 and the side wall of the Z-shaped plate 35, and an alarm 37 is fixedly connected to the top of the adjustment block 5, and the touch sensor 36 is electrically connected to the alarm 37 through the controller;

[0038] When the turntable 25 is rotated to unscrew the screw 13, the squeezing of the Z-type plate 35 will be gradually released, and then the elastic force of the spring 38 will push the Z-type plate 35 to slide outward, and then touch the touch end of the touch sensor 36, and the switching of the water flow direction is completed. At this time, if the maintenance personnel forget to switch the water flow direction and directly turn on the power, the touch sensor 36, the controller and the alarm 37 will be powered on, and then the touch sensor 36 will transmit the signal to the controller, and the controller will control the touch sensor 36 to turn on the power to emit an alarm sound and a prompt light to remind the maintenance personnel to avoid the phenomenon of long-term dry burning and improve the safety performance of the device during use. Finally, the maintenance personnel realizes that the water flow has not been switched, and the screw 13 is screwed in by rotating the turntable 25 to switch the water flow. At this time, the Z-type plate 35 will be gradually squeezed to slide in the fixed frame 33, and then the spring 38 will be gradually compressed, so that the Z-type plate 35 is away from the touch end of the touch sensor 36, thereby controlling the power of the alarm 37 to be turned off.

[0039] The basic principles, main features and advantages of the present invention are shown and described above.
