Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a storage-type air conditioner. Background Art

[0002] Air conditioners are used to adjust the indoor temperature. Especially in summer when it is hot, they can keep the indoor temperature at a relatively low and comfortable level, and are one of the essential household appliances in modern families. Generally, the air conditioners in the prior art use a compressor system for refrigeration, which will consume a large amount of electric energy during long-term operation, and is not conducive to energy conservation and environmental protection. China has a vast territory, and there is a large temperature difference between day and night in some areas (such as Xinjiang), with high temperatures during the day and low temperatures at night. The air conditioner is generally used for refrigeration during the day, and its utilization rate is not as high as that in other regions. At the same time, the relatively high energy consumption (electric energy) will also result in a high usage cost, increasing the consumption burden of residents. Therefore, generally, the air conditioners in the prior art are not suitable for use in areas with large temperature differences between day and night. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a storage-type air conditioner, which solves the problems of low equipment utilization rate and high energy consumption leading to high usage cost when the air conditioner in the prior art is used in areas with large temperature differences between day and night.

[0007] One end of the heat exchange tube extends outside the inner casing and is connected to the water storage container through a first pump body, and the other end is connected to a spray pipe extending into the outer casing.

[0008] In the above embodiments, in areas with large day-night temperature differences, when the night temperature is low, the first pump body can be started to circulate water between the water storage container and the cooler. During the circulation, the water in the cooler can be cooled by the relatively low-temperature outdoor air, so that the temperature of the water in the water storage container is reduced to store cold energy. When the day temperature is high, the first fan is turned on to blow air into the inner casing. The water in the water storage container exchanges heat with the air at the heat exchange pipes in the inner casing, reducing the air temperature, and then the air is blown into the room to achieve the purpose of cooling the room. In this way, the climate characteristics of large day-night temperature differences are reasonably utilized to cool the room during the day. The power consumption is less than that of the compressor air conditioner in the prior art, and it is more suitable for use in areas with large day-night temperature differences, solving the problems of low equipment utilization rate and high energy consumption leading to high use costs when the air conditioner in the prior art is used in areas with large day-night temperature differences.

[0009] Further, the spray pipe is also connected to a spray head located at the upper end inside the outer casing.

[0010] Further, an opening is provided at the top of the outer casing, and a casing top is fixedly connected to the top of the outer casing and completely covers the opening.

[0011] Further, the ventilation holes are arranged on the side wall of the outer casing, and a water guide plate is fixedly connected above each ventilation hole inside the outer casing. The water guide plate is inclined and its lower end extends towards the inside of the outer casing.

[0012] Further, a second fan is provided outside the outer casing. The second fan is connected to a duct, and the duct extends into the outer casing and has an outlet facing downwards.

[0013] Further, the lower end of the outer casing is of a funnel structure, and a wind collecting cylinder is fixedly connected to the inner wall. The outlet is located inside the wind collecting cylinder, and a number of liquid guide holes connected to the inner wall of the outer casing are provided at the lower end of the wind collecting cylinder.

[0014] Further, one end of the duct located inside the outer casing is fixedly connected to a wind guide cover with an opening facing downwards.

[0015] Further, it further includes a first three-way valve with three interfaces, two of which are respectively connected to the spray pipe and the heat exchange pipe, and the other is connected to a first pipe. The first pipe is also communicated with the water storage container, and a second pump body is installed on the first pipe.

[0016] Further, a water inlet pipe is installed on the water storage container.

[0017] Further, it further includes a second three-way valve with three interfaces, two of which are connected to the first pipe, and the other is connected to a second pipe. The second pipe is communicated with the water storage container.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] Rationally utilize the climatic characteristics of the regions with large day-night temperature differences in our country. When the temperature is low at night, cool the water to store cold energy. When the temperature is high during the day and indoor cooling is required, utilize the cold energy stored in the water to cool the relatively high indoor temperature. The power consumption of this solution is less than that of the compressor air conditioner in the prior art, and it is more suitable for use in regions with large day-night temperature differences, solving the problems of low equipment utilization rate and high energy consumption in the prior art when using air conditioners in regions with large day-night temperature differences, resulting in high usage costs.

[0026] In the exemplary embodiments, such as Figure 1 、2 As shown in the figure, this embodiment provides a storage-type air conditioner, which includes:

[0027] The first unit, the first unit includes an inner casing 1, and a heat exchange tube 2 partially located inside the inner casing 1, and a first fan 3 connected to the inner casing 1. An air outlet 4 is further provided on the inner casing 1. One side of the inner casing 1 is fixed to the indoor wall 6 through a first mounting plate 5. The first fan 3 can be fixed to the outdoor wall 6 through a second mounting plate 7. The first mounting plate 5 and the second mounting plate 7 can be jointly connected to the wall 6 through a double-headed bolt 8. Such installation has better stability. At the same time, the first fan 3 is installed outdoors, and the noise generated during operation has less impact on the indoor environment. The air inlet of the first fan 3 can be communicated with the indoor space, so that the indoor air circulates due to the operation of the first fan 3. More specifically, the air inlet pipe 9 of the first fan 3 passes through the wall 6 and is communicated with the indoor space, and the air outlet pipe 10 passes through the wall 6, the first mounting plate 5, the second mounting plate 7 and is communicated with the inside of the inner casing 1. The part of the heat exchange tube 2 located inside the inner casing 1 can be a spiral coil 11, extending from one end of the inner casing 1 to the other end and located between the air outlet pipe 10 and the air outlet 4. The air introduced by the first fan 3 passes through the heat exchange tube 2 and then enters the indoor space through the air outlet 4. The two ends of the heat exchange tube 2 can pass through the inner casing 1 in a straight pipe state, and then extend to the outdoor through the wall 6, or can also extend to the outdoor through the wall 6, the first mounting plate 5, and the second mounting plate 7; In another embodiment, the first fan 3 can also be installed indoors, specifically, it can also be located inside the inner casing 1;

[0028] The second unit, the second unit includes a water storage container 12 and a cooler. Water is stored in the water storage container 12. The water storage container 12 can also be provided with a heat preservation interlayer to improve the heat preservation and heat insulation performance of the water storage container 12. The cooler includes an outer casing 13, and a plurality of ventilation holes 14 communicating its inside and outside are provided on the outer casing 13. The outer casing 13 is fixedly arranged directly above the water storage container 12, and the bottom of the outer casing 13 is communicated with the water storage container 12 through a connecting pipe 19. The water storage container 12 can adopt a box structure with a relatively large volume, which can hold more water and can also be used for the fixed installation of the outer casing 13. Specifically, the water storage container 12 is installed outdoors, and the outer casing 13 and the top surface of the water storage container 12 are fixedly installed through a connecting column 15. The provided ventilation holes 14 enable good communication between the inside and outside of the outer casing 13, and the temperature inside the outer casing 13 will also be relatively low;

[0029] One end of the heat exchange tube 2 extends outside the inner casing 1 and is connected to the water storage container 12 through the first pump body 16, and the other end is connected with a nozzle 17 extending into the outer casing 13. A number of spray heads 18 can also be installed on the nozzle 17, so that water can be introduced into the outer casing 13 in a spray manner, so that the water can better contact the surrounding air, thereby achieving a better cooling effect.

[0030] In the above-mentioned embodiment, in the area with large day-night temperature difference, when the night temperature is low, the first pump body 16 can be started to make the water circulate between the water storage container 12 and the cooler. When circulating, the water in the cooler can be cooled by the relatively low-temperature air outside, so that the temperature of the water in the water storage container 12 is reduced to store cold energy. When the day temperature is high, the first blower 3 is turned on to blow air into the inner casing 1. The water in the water storage container 12 exchanges heat with the air at the heat exchange tube 2 in the inner casing 1, so that the air temperature is reduced, and then blown into the room to form a refrigeration cycle in the room, so as to achieve the purpose of cooling the room. In this way, the climate characteristics of large day-night temperature difference are reasonably utilized to achieve the purpose of cooling the room during the day. The power consumption is less than that of the compressor air conditioner in the prior art, and it is more suitable for use in the area with large day-night temperature difference, solving the problems of low equipment utilization rate and high energy consumption leading to high use cost when the air conditioner in the prior art is used in the area with large day-night temperature difference; more specifically, the nozzle 17 and the spray heads 18 can be located above all the ventilation holes 14, so that the water can fully contact the air around the ventilation holes 14 during the downward movement of the water spray, achieving a better cooling effect;

[0031] More specifically, the connecting pipe 19 is arranged between the bottom of the outer casing 13 and the top surface of the water storage container 12, so that the water in the outer casing 13 can smoothly flow into the water storage container 12. Further, a second blower 20 is arranged outside the outer casing 13. The second blower 20 is connected with a duct 21, and the duct 21 extends into the outer casing 13 and has an outlet arranged downward. During specific operation, the second blower 20 can be not started (cooling is achieved through the ventilation holes 14), or it can be started. When the second blower 20 is started, the air flow inside the outer casing 13 can be accelerated through the second blower 20, so that the cooling efficiency is further improved. An opening 22 is arranged at the top of the outer casing 13, and a top shell 23 which is located above the opening 22 and completely covers the opening 22 is fixedly connected to the top of the outer casing 13. The second blower 20 can blow air into the outer casing 13 through the duct 21, and the blown air can also be the cold air outside the outer casing 13 (the air inlet of the second blower 20 is communicated with the outside of the outer casing 13). The air flow speed inside the outer casing 13 is increased, and the outlet of the duct 21 is located at the lower end of the outer casing 13. The downward arrangement can prevent the sprayed water from directly falling into the duct 21. The blown air moves downward and then turns back upward, so that the air inside the outer casing 13 generally moves upward, which just forms a convection with the sprayed water, so as to better contact the water and enable the water to be cooled efficiently, and then be discharged through the upper outlet (or discharged through some of the ventilation holes 14). The top shell above the outlet plays a protective role, preventing external impurities from directly falling into the outer casing 13, and also preventing rainwater, etc. from falling into the outer casing 13 (a water inlet pipe 38 can be added on the water storage container 12 or the outer casing 13 for adding water into the water storage container 12). Further, an annular protective net 24 can be added between the top shell and the outer casing 13 to better prevent external impurities and also not affect the air flow through;

[0032] More specifically, the ventilation holes 14 are arranged on the side wall of the outer casing 13, and a water guide plate 25 is fixedly connected above each ventilation hole 14 inside the outer casing 13. The water guide plate 25 is inclined and the lower end extends toward the inside of the outer casing 13. During spraying, part of the water will be close to the inner wall of the outer casing 13, but this part of the water is blocked by the water guide plate 25 and will not pass through the ventilation holes 14 to the outside of the outer casing 13. There is also a gap between the water guide plate 25 and the ventilation holes 14 for air to pass through, so the normal cooling will not be affected.

[0033] In a more detailed exemplary solution, such as Figure 1 、 2As shown, the lower end of the outer casing 13 is a funnel structure, and a wind collecting cylinder 26 is fixedly connected to the inner wall. The wind collecting cylinder 26 can be set with a larger upper end, and the outlet is located inside the wind collecting cylinder 26. The connecting pipe 19 is located directly below the wind collecting cylinder 26. A number of liquid guiding holes 27 connected to the inner wall of the outer casing 13 are also provided at the lower end of the wind collecting cylinder 26. The setting of these liquid guiding holes 27 enables the water outside the wind collecting cylinder 26 to smoothly pass through and then reach the bottom of the outer casing 13, and then smoothly return to the water storage container 12 through the connecting pipe 19. Furthermore, one end of the air duct 21 located inside the outer casing 13 is fixedly connected with a wind guiding cover 28 with an opening 22 facing downwards. The lower end of the wind guiding cover 28 is the outlet. A conical top 29 is also provided inside the wind guiding cover 28. The wind guiding cover 28 can be a structure with a smaller upper part and a larger lower part. The cooperation of the wind guiding cover 28 and the conical top 29 enables the air introduced by the second fan 20 to disperse outwards and enter the wind collecting cylinder 26, then fold back after passing through the bottom of the outer casing 13, and then enter the upper outer casing 13 after passing through the wind collecting cylinder 26.

[0034] As Figure 1 , 2 shown, in a more detailed exemplary solution, a plurality of rotating plates 30 distributed from top to bottom are rotatably installed inside the air outlet 4. Specifically, the air outlet 4 is a long strip-shaped frame structure. Both ends in the length direction of the rotating plate 30 are rotatably connected to the inner wall of the air outlet 4 through mounting shafts 37. The rotating plates 30 are arranged at equal intervals to form a plurality of air ducts. The rotation angle of the rotating plate 30 can be adjusted by rotation, so as to adjust the air flow direction entering the room. More specifically, an arc-shaped orifice plate 31 covering the connection between the air outlet pipe 10 and the inner casing 1 is also provided inside the inner casing 1. A number of small holes are provided on the arc-shaped orifice plate 31. These small holes enable the air of the first fan 3 to enter the inner casing 1 in a wider range, and then exchange heat with the heat exchange tube 2 more fully to cool down.

[0035] As Figure 1 shown, in a further exemplary solution, the air conditioner further includes a first three-way valve 32 with three interfaces, and two of them are respectively connected to the spray pipe 17 and the heat exchange tube 2, and the other is connected to a first pipe 33. The first pipe 33 is also connected to the water storage container 12, and a second pump body 34 is installed on the first pipe 33. Furthermore, the air conditioner further includes a second three-way valve 35 with three interfaces, and two of them are connected to the first pipe 33, and the other is connected to a second pipe 36. The second pipe 36 is connected to the water storage container 12. The settings of the first pipe 33 and the second pipe 36 enable this air conditioner to operate in different circulation modes during the day and at night. Specifically, the usage method of the air conditioner provided in this solution includes the following steps:

[0036] When the indoor temperature is low at night, the first cycle or the second cycle is carried out to cool the water and store cold energy, where:

[0037] The first cycle includes: starting the first pump body 16 so that the water in the water storage container 12 is introduced into the nozzle 17 through the heat exchange tube 2, then into the outer casing 13, and then back to the water storage container 12. At this time, the first three-way valve 32 connects the heat exchange tube 2 and the nozzle 17, and the water is introduced into the outer casing 13 through the spray head 18. The second fan 20 can be started or not started;

[0038] The second cycle includes: starting the second pump body 34 so that the water in the water storage container 12 enters the nozzle 17 through the first pipeline 33, then into the outer casing 13, and then back to the water storage container 12. At this time, the first three-way valve 32 connects the first pipeline 33 and the nozzle 17, and the second three-way valve 35 connects the first pipeline 33. The water does not pass through the heat exchange tube 2, and the cycle can be realized more quickly. At the same time, the second fan 20 can be started or not started;

[0039] When the outdoor temperature is high during the day, the indoor temperature will also be relatively high. Therefore, it is necessary to cool the indoor by performing the third cycle or the fourth cycle, where:

[0040] The third cycle includes: starting the first pump body 16 so that the water in the water storage container 12 is introduced into the nozzle 17 through the heat exchange tube 2, then into the outer casing 13, and then back to the water storage container 12. During the process, the first fan 3 blows air into the inner casing 1, and after passing through the heat exchange tube 2, it is introduced into the room from the air outlet 4. The air inlet of the first fan 3 is connected to the room. At this time, the first three-way valve 32 connects the heat exchange tube 2 and the nozzle 17, and the water enters the outer casing 13 through the spray head 18 and then enters the water storage container 12 through the connecting pipeline 19 to realize the cycle;

[0041] The fourth cycle includes: starting the first pump body 16 so that the water in the water storage container 12 is introduced into the nozzle 17 through the heat exchange tube 2, and then returns to the water storage container 12 through the first pipeline 33 and the second pipeline 36. During the process, the first fan 3 blows air into the inner casing 1, and after passing through the heat exchange tube 2, it is introduced into the room from the air outlet 4. The air inlet of the first fan 3 is connected to the room. At this time, the first three-way valve 32 connects the heat exchange tube 2 and the first pipeline 33, and the second three-way valve 35 connects the first pipeline 33 and the second pipeline 36. The water enters the first pipeline 33 through the heat exchange tube 2 and then directly returns to the water storage container 12 through the second pipeline 36, and only circulates between the water storage container 12 and the heat exchange tube 2. In this way, it can avoid the water in the outer casing 13 from being affected by the higher outdoor temperature and heating up faster, and can maintain the cooling effect for a longer time.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
