Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air duct structure of an air conditioner in a shed. Background Art

[0002] Air conditioners are common household appliances for daily indoor temperature control and are often installed in some sheds, such as glass sheds. They are mainly composed of an outdoor unit and an indoor unit. The indoor unit is installed indoors. After the air passes through the air inlet of the indoor unit, it exchanges heat through the evaporator, and then is input into the room through the heat exchange fan and the air outlet of the indoor unit to achieve indoor heat exchange and temperature control. When the indoor space is large, the heat exchange efficiency is often slow, resulting in relatively long heat exchange and temperature control time. There is room for improvement. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide an air duct structure for an air conditioner in a shed, which solves the problem that the heat exchange and temperature control time is relatively long when the existing air conditioner is used.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an air duct structure for air conditioning in a shed, including an air conditioner installed on a shed, a guide cavity is provided inside the shed, the air conditioner is provided with a first air inlet connected to the guide cavity, a plurality of second air inlets connected to the guide cavity are provided at intervals on the surface of the shed, a plurality of guide fans are provided at intervals in the guide cavity, when the guide fans are operated, a unidirectional airflow is formed in the guide cavity to the first air inlet, a shielding piece is provided in the guide cavity, one end of the shielding piece is connected to the inner wall of the guide cavity, and the other end is tilted at the second air inlet to prevent the unidirectional airflow from being output from the second air inlet.

[0005] Furthermore, the shelf includes crossbeams and columns, the guide cavity is formed in the crossbeams and / or the columns, and the air conditioner is installed on the crossbeams and / or the columns accordingly.

[0006] By adopting the above technical solution, the air conditioner is installed on the cross beam, and the guide cavity is formed in the cross beam. In summer, the high indoor temperature is easy to gather at a high place. Therefore, the guide cavity is set on the cross beam, which is convenient for using multiple second air inlets on the cross beam to synchronously absorb the indoor high temperature in multiple directions, thereby improving the heat exchange treatment effect of the air conditioner.

[0007] Furthermore, the air conditioner includes an inner casing, an evaporator and a heat exchange fan arranged in the frame, the evaporator is arranged on one side close to the first air inlet, and the heat exchange fan is located on the other side of the evaporator. The output end of the heat exchange fan is connected to a guide air duct, and the guide air duct includes an output air duct output to the outside of the inner casing and a circulation air duct output toward the side of the evaporator close to the first air inlet. A solenoid valve is provided in the circulation air duct for opening or closing the circulation air duct.

[0008] By adopting the above technical scheme, through the setting of the circulating air duct and the solenoid valve, the opening or closing of the circulating air duct can be controlled by the switch of the solenoid valve. When the indoor temperature is high, or when the refrigerant liquid in the evaporator becomes less and the temperature control effect of the air conditioner is poor, the circulating air duct can be opened, so that part of the airflow after heat exchange can be input into the evaporator again, and then secondary temperature control can be performed, thereby effectively improving the temperature control effect of the air conditioner.

[0009] Furthermore, an air outlet is provided on the surface of the inner casing to guide the airflow output from the guide air duct to the outside of the inner casing.

[0010] By adopting the above technical solution and setting the air outlet, it is convenient to guide the airflow after heat exchange of the evaporator out of the room.

[0011] Furthermore, an exhaust fan is installed at the air outlet.

[0012] By adopting the above technical solution, the provision of the exhaust fan helps to speed up the discharge of the airflow after heat exchange inside the inner casing to the indoor room, thereby increasing the air outlet rate of the air conditioner.

[0013] Furthermore, a confluence groove is provided on the inner casing at the bottom of the evaporator.

[0014] By adopting the above technical solution and setting the confluence trough, it is convenient to collect the condensed water generated by the evaporator, so as to facilitate centralized collection and treatment.

[0015] Furthermore, the first air inlet is arranged on the inner casing, and a guide port is arranged on the cross beam corresponding to the position of the first air inlet, so that the guide cavity is connected with the first air inlet through the guide port.

[0016] By adopting the above technical solution and setting the guide port, it is convenient to connect the inner casing with the guide cavity.

[0017] Furthermore, the circulating air ducts are arranged outside the heat exchange fan at intervals in a plurality of ways.

[0018] By adopting the above technical solution and setting the intervals, it is possible to avoid the circulating air duct from blocking the first air inlet, so that the airflow in the guide cavity can smoothly enter the inner casing.

[0019] Compared with the prior art, the advantages of the utility model are:

[0020] 1. The utility model opens a guide cavity in the shed, and arranges a plurality of second air inlets at intervals on the surface of the shed, and then connects the first air inlet of the air conditioner with the guide cavity. In this way, when the air conditioner is running, the airflow in the shed or the room will enter the air conditioner through the plurality of second air inlets and the first air inlet in sequence, so as to perform heat exchange through the air conditioner. The plurality of distributed second air inlets are conducive to quickly absorbing and collecting the air conditioning in various corners of the room into the air conditioner, and then the air intake heat exchange effect of the air conditioner is improved through the multi-position synchronous air intake method.

[0021] 2. In the utility model, a guide fan is arranged in the guide cavity, which helps to speed up the flow of gas in the guide cavity, so that a one-way airflow toward the air conditioner is formed in the guide cavity. Due to the flow of air in the guide cavity, negative pressure is used to make indoor air quickly enter the guide cavity, thereby improving air intake efficiency. The setting of the shielding sheet prevents the airflow from directly entering the room through the second air inlet when the guide fan is running, so that the indoor airflow can only enter the guide cavity through the second air inlet and will not be output from the second air inlet, thereby ensuring that the multiple second air inlets on the shed always maintain a stable suction force to synchronously absorb air from all angles in the shed.

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 and 2The air conditioner 200 is installed on the shelf 100. The shelf 100 includes a beam 103 and a column 104 supporting the beam 103. Taking the rectangular cubic shelf 100 as an example, four beams 103 are combined to form a rectangular beam 103 structure. The air conditioner 200 is installed on the beam 103. A guide cavity is formed inside the beam 103, and a plurality of second air inlets 101 connected to the guide cavity are arranged at intervals on the surface of the beam 103 along its length direction. The air conditioner 200 has a first air inlet 110 connected to the guide cavity. When the air conditioner 200 is running, the indoor air enters the guide cavity through the first air inlet 110, and then passes through the guide cavity. The air enters the flow cavity and the first air inlet 110 into the air conditioner 200. After the air conditioner 200 performs heat exchange treatment on the air, it is input into the room again to realize heat exchange and temperature control. In order to improve the air intake efficiency of the air conditioner 200, a plurality of guide fans 120 are arranged at intervals in the guide cavity. The output directions of the guide fans 120 remain in the same direction and are uniformly directed toward the first air inlet 110. In this way, when a plurality of guide fans 120 are operated synchronously, a unidirectional airflow toward the first air inlet 110 will be formed inside the guide cavity, and a negative pressure will be generated at the second air inlet 101 through the flow of the guided airflow, so as to realize the purpose of quickly absorbing indoor air into the air conditioner 200.

[0031] Furthermore, a shielding piece 130 is provided on the inner wall of the guide cavity at the upper end of the second air intake port, one end of the shielding piece 130 is fixed inside the guide cavity, and the other end is tilted at the upper end of the second air intake port. In this way, the shielding piece 130 is used to prevent the airflow from directly entering the room through the second air inlet 101 when the guide fan 120 is running, so that the indoor airflow can only enter the guide cavity through the second air inlet 101 and will not be output from the second air inlet 101, thereby ensuring that the multiple second air inlets 101 on the rack 100 always maintain a stable suction.

[0032] In this embodiment, refer to Figure 3The air conditioner 200 is commonly available in two forms: split type and integrated type. Both are applicable to the present embodiment. The split type air conditioner 200 is used as an example below. The air conditioner 200 includes an indoor unit and an outdoor unit. The indoor unit includes an inner casing, an evaporator 220, a heat exchange fan 210 and other components. In order to further improve the heat exchange and temperature control effect of the air conditioner 200, one side of the evaporator 220 is arranged close to the first air inlet 110, and the heat exchange fan 210 is arranged on the other side of the evaporator 220. After the indoor air flow enters the inner casing through the first air inlet 110, it exchanges heat through the evaporator 220. The heat exchange fan 210 inputs the air flow after heat exchange into the room again to achieve the temperature control effect of the air conditioner 200. The output end of the heat exchange fan 210 is connected to a guide air duct 230. The guide air duct 230 includes The output air duct 232 that delivers air to the indoor room and the circulating air duct 231 that outputs toward the evaporator 220 on the side close to the first air inlet 110, the circulating air duct 231 is provided with a solenoid valve 233 for opening or closing the circulating air duct 231. The advantage of this is that through the setting of the circulating air duct 231 and the solenoid valve 233, the opening or closing of the circulating air duct 231 can be controlled by switching the solenoid valve 233. When the indoor temperature is high, or when the refrigerant liquid in the evaporator 220 becomes less and the temperature control effect of the air conditioner 200 is poor, the circulating air duct 231 can be opened to allow part of the airflow after heat exchange to be input into the evaporator 220 again, and then secondary temperature control can be performed, thereby effectively improving the temperature control effect of the air conditioner 200.

[0033] In this embodiment, an air outlet 240 is provided on the surface of the inner casing, and the output air duct 232 can be directly facing the air outlet 240. The air outlet 240 can be arranged on the side, bottom or end of the inner casing. When the output air duct 232 is aligned with the air outlet 240, the airflow after heat exchange is directly pushed into the room through the heat exchange fan 210. When the two are staggered, for example, the output direction of the output air duct 232 is set horizontally, and the air outlet 240 is set at the bottom of the inner casing, the airflow after heat exchange can also be passively transported to the room when the inner casing is in a positive pressure environment, thereby achieving a passive air outlet effect.

[0034] In order to further increase the air volume of the inner casing, refer to Figure 3 An exhaust fan may be installed at the air outlet 240 to improve the air flow efficiency after heat exchange.

[0035] In this embodiment, a guide hole is opened on the beam 103 corresponding to the position of the first air inlet 110 of the inner casing to ensure smooth communication between the guide cavity and the inner casing. It can be imagined that an exhaust fan can also be added at the guide port 102 or the first air inlet 110 to improve the transmission efficiency of the airflow in the guide cavity into the inner casing.

[0036] In this embodiment, refer to Figure 4The circulating air duct 231 can be arranged at the upper end or the lower end of the inner casing, or at both the upper and lower ends or at other positions. In order to avoid the setting of the circulating air duct 231 hindering the airflow in the guide cavity from merging into the inner casing, the circulating air duct 231 can be arranged in multiple intervals, and the gaps between adjacent circulating air ducts 231 are used to ensure that the airflow in the guide cavity can stably enter the inner casing.

[0037] In the above implementation, taking the inner casing installed on the beam 103 as an example, the second air inlet 101 is arranged on the beam 103 at intervals. It can be imagined that the air conditioner 200 can also be installed on the column 104, and its guide cavity can also be opened in the column 104, or the column 104 and the beam 103 are connected through the guide cavity, and the second air inlet 101 can be arranged on the beam 103 or the column 104, or the beam 103 and the column 104 are both set. In this way, the entire shed will be under the negative pressure of the guided airflow, and the second air inlet 101 arranged at multiple angles will be used to synchronously ventilate the airflow in various places in the room, thereby improving the air intake and ventilation efficiency of the air conditioner 200.

[0038] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
