Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning air outlets, in particular to an air outlet structure of a central air-conditioning. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. When the cold and heat source systems of the central air-conditioning are working, the gas is cooled or heated, and then transported to the room by air supply ducts and other equipment. The indoor unit of this central air-conditioning system only needs to be switched on and off and the wind direction adjusted. In order to achieve automatic adjustment of the wind direction, a central air-conditioning outlet structure is required.

[0003] After the indoor air outlet of most central air conditioners is opened, the user needs to adjust the wind direction. For example, in winter, the air outlet of the central air conditioner outputs hot air. Since the hot air flow will rise, in order for the hot air to circulate quickly in the house, it is necessary to use the air outlet to direct the hot air toward the ground. In the prior art, wind direction adjustment can only rely on manual control. Forgetting to control the wind direction will result in low indoor temperature regulation efficiency.

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Combine the following Figures 1 to 6 As shown, the embodiment of the utility model provides an air outlet structure of a central air conditioner, comprising:

[0042] The housing 1 has a plurality of air guide components equidistantly arranged on the inner wall of the housing 1, and the plurality of air guide components are distributed up and down;

[0043] The air guide assembly includes:

[0044] An air guide plate 2, the air guide plate 2 is rotatably arranged on the inner wall of the housing 1;

[0045] Gear 10, the gear 10 is fixed on the side wall of the air guide plate 2, and the gear 10 is rotatably arranged on the inner wall of the housing 1;

[0046] A transmission assembly, which is rotatably disposed on the inner wall of the housing 1 and is used to drive the gear 10 to rotate;

[0047] An air inlet hole 3 is provided on the side wall of the housing 1;

[0048] The gas storage box 4 is fixed on the inner wall of the shell 1 and is arranged close to the air inlet 3. The gas storage box 4 is filled with nitrogen;

[0049] Two fins 5, the two fins 5 are respectively fixed on the top and bottom of the air storage box 4;

[0050] Pneumatic assembly: the pneumatic assembly is fixed on the inner wall of the housing 1 and is arranged close to the transmission assembly.

[0051] During installation, fix the gas pipeline and the air inlet 3, and install the housing 1 indoors;

[0052] When in use, when the cold and hot sources of the central air conditioner are working, gases with different temperatures are generated and enter the housing 1 through the gas pipeline and the air inlet 3;

[0053] When the gas entering the housing 1 is at a relatively high temperature, the heat exchange of the fins 5 causes the nitrogen in the gas storage box 4 to expand, thereby driving the pneumatic component to extend, and cooperating with the transmission component to rotate the gear 10. The gear 10 rotates and drives the air guide plate 2 to rotate. Through the guiding effect of each air guide plate 2, the hot air flow is blown downward. According to the principle that hot air rises, the temperature of each part of the room can be quickly increased.

[0054] On the contrary, when the temperature of the gas entering the shell 1 is low, the ammonia in the gas storage box 4 contracts, and the pneumatic component contracts. At this time, under the action of the gravity of the transmission component itself, the air guide plate 2 can rotate. Compared with the output of hot air, the air guide plate 2 rotates in the opposite direction at this time, and then outputs cold air to the indoor roof. Combined with the sinking of cold air, the temperature in various places in the room drops evenly.

[0055] Furthermore, the transmission assembly includes:

[0056] A rack plate 9, the rack plate 9 is slidably arranged on the inner wall of the housing 1, and the rack plate 9 is meshed with each gear 10;

[0057] A transmission rod 11, the transmission rod 11 is rotatably arranged on the inner wall of the housing 1, and the rotation axis of the transmission rod 11 is arranged close to the rack plate 9;

[0058] The sliding rod 12 is slidably inserted at the end of the transmission rod 11, and the sliding rod 12 is rotatably connected to the rack plate 9.

[0059] Furthermore, it also includes:

[0060] Iron block 8, iron block 8 is fixed on the side wall of rack plate 9;

[0061] The electric push rod 6 is fixed on the bottom inner wall of the housing 1 near the iron block 8, and an electromagnet 7 is fixed on the output end of the electric push rod 6.

[0062] When the air flow temperature in the housing 1 is low, the rack plate 9 is lowered under the gravity of the iron block 8, thereby driving the gear 10 to rotate, so that each air guide plate 2 rotates. Since there is friction between the air guide plate 2 and the housing 1, under the gravity of the iron block 8, each air guide plate 2 cannot be overlapped, thereby facilitating the output of cold air.

[0063] When the central air conditioner is not in use, the switch of the electromagnet 7 is turned on, and the electromagnet 7 attracts the iron block 8. At this time, the switch of the electric push rod 6 is turned on, and the electric push rod 6 drives the electromagnet 7 to descend, and then drives the iron block 8 to descend, and through the rack plate 9, each gear 10 rotates, so that each air guide plate 2 can overcome the friction between the shell 1, so that each air guide plate 2 can overlap, and the shell 1 is closed by the air guide plate 2 to avoid dust accumulation in the shell 1.

[0064] Further, the pneumatic assembly includes:

[0065] A sliding rod 12, the sliding rod 12 is fixed on the inner wall of the housing 1, and the sliding rod 12 is located below the end of the transmission rod 11;

[0066] A sleeve 13, wherein the sleeve 13 is fixed on the top of the sliding rod 12;

[0067] A piston 15, the piston 15 is slidably disposed on the inner wall of the sleeve 13;

[0068] A sleeve rod 14, which is fixed to the top of the piston 15;

[0069] The connecting pipe 16 has one end which penetrates and is fixed at the bottom of the sleeve 13 , and the other end of the connecting pipe 16 is communicated with the air storage box 4 .

[0070] Furthermore, the top of the sleeve rod 14 is a spherical structure.

[0071] When the nitrogen in the gas storage box 4 expands, the nitrogen enters the sleeve 13 through the connecting pipe 16 and is in the space below the piston 15, and pushes the piston 15 up, thereby driving the sleeve rod 14 to rise. When the top of the sleeve rod 14 contacts the transmission rod 11, it continues to push the transmission rod 11. Since the rotation position of the transmission rod 11 is close to the rack plate 9, the sleeve rod 14 can drive the rack plate 9 to move upward through the transmission rod 11 and the sliding rod 12 by using the lever principle.

[0072] On the contrary, when the nitrogen in the gas storage box 4 contracts, the sleeve rod 14 contracts into the sleeve 13 under the action of the piston 15. At this time, the sleeve rod 14 and the transmission rod 11 are not in contact, and then the rack plate 9 is driven down under the gravity of the iron block 8.

[0073] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
