Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning unit. Background Art

[0002] The air conditioner's surface cooler cools and dehumidifies the incoming air to achieve the purpose of cooling and drying. When the surface cooler is cooling, condensed water will be generated on the surface. When the air conditioner unit is selected, the air volume and other parameters have been determined. Without adding a water baffle, if the unit works with excessive air volume, the condensed water on the surface cooler may be blown out, which cannot meet the requirements of multiple working conditions. In addition, the resistance generated by the surface cooler of the unit when adding a water baffle and ventilation mode is invalid energy consumption, which is not conducive to energy saving and environmental protection. Utility Model Content

[0004] The utility model provides an air conditioning unit, comprising:

[0005] Surface cooler;

[0006] A connecting piece, the connecting piece is arranged on the surface cooler; and

[0007] The rotating mechanism comprises a gear, a rack and a driving member, wherein the gear is arranged on the connecting member and meshes with the rack, and the driving member is connected to the rack.

[0008] In one embodiment, the length of the connecting member is greater than the length of the surface cooler, and the gear is disposed at an end of the connecting member.

[0009] In one embodiment, the diameter of the gear is greater than the thickness of the cooler, and the gear is fixed to the connecting member by a first fastener.

[0010] In one embodiment, the connecting member includes a bottom plate and a side plate, the side plate is arranged at an end of the bottom plate, and the first fastener fixes the gear to the side plate along the axial direction of the gear.

[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 2As shown, this embodiment provides an air conditioning unit, including a surface cooler 1, a connecting member 2 and a rotating mechanism 3, wherein the connecting member 2 is arranged on the surface cooler 1. The rotating mechanism 3 includes a gear 31, a rack 32 and a driving member 33, wherein the gear 31 is arranged on the connecting member 2 and meshes with the rack 32, and the driving member 33 is connected to the rack 32.

[0028] Figures 2 to 4 The arrow in the figure indicates the direction of air flow. The driving member 33 can drive the rack 32 to reciprocate, and the rack 32 drives the gear 31 to rotate, so that the surface cooler 1 also rotates, thereby changing its posture and windward area in the air-conditioning unit.

[0029] contrast Figure 2 and Figure 3 ,exist Figure 3 In the embodiment, the surface cooler 1 is tilted toward the air inlet side, and its top is farther away from the air supply side, thereby preventing condensed water from falling on the air supply side and causing water blowing.

[0030] like Figure 4 As shown, when the air conditioning unit operates in the ventilation mode, the surface cooler 1 reduces the airflow resistance by keeping parallel with the wind direction, thereby meeting the requirements of energy saving and environmental protection.

[0031] In this embodiment, the rotation angle of the cooler 1 is not less than 90 degrees, so that the cooler 1 can be switched among a horizontal posture, a vertical posture and an inclined posture.

[0032] In this embodiment, the driving member 33 is a cylinder, which switches the surface cooler 1 among the above three different working modes by moving according to a preset stroke, thereby meeting the requirements of multiple working conditions.

[0033] The specific working principle is as follows:

[0034] After starting the unit, detect the outdoor temperature. When the outdoor temperature is less than the preset value X, the unit operates in the ventilation mode. In this mode, the driving member 33 advances S1 according to the preset stroke, and the stroke of the rack 32 is S1. The rack 32 drives the gear 31 on the cooler 1 to rotate, so that the entire cooler 1 is parallel to the wind direction, which greatly reduces the resistance and energy consumption of the unit. After running for a period of time, turn off the unit, the rack 32 moves back S1, and the cooler 1 is perpendicular to the wind direction, that is, the unit returns to the state before operation, and finally the unit is powered off. When the outdoor temperature is greater than the preset value X, and the difference between the outdoor temperature and the preset value X is X1 <5°C, the unit operates in the rated cooling mode. At this time, the driving member 33 does not work, so that the cooler 1 is perpendicular to the wind direction, the motor works at the rated speed, and the water valve opening is 2 / 3 of the preset opening. When the outdoor temperature is greater than the preset value X, and the difference between the outdoor temperature and the preset value X is X1≥5℃, the unit operates in high-end cooling mode, the driving member 33 advances S2 according to the preset stroke, the stroke of the rack 32 is S2, the rack 32 drives the gear 31 on the cooler 1 to rotate, so that the entire cooler 1 is 60° with the wind direction, the motor operates in high gear, the water valve is fully opened, and the cooling performance of the unit is increased. After running for a period of time, the indoor temperature is detected. When the difference between the indoor temperature and the preset value X2≥3℃, the unit continues to operate in high-end cooling. When the difference between the indoor temperature and the preset value X2<3℃, the unit returns to the rated speed gear, the water valve opening is 2 / 3 of the preset opening, the rack 32 moves back S2, and the unit operates in rated cooling mode.

[0035] like Figure 1 As shown, the length of the connecting member 2 is greater than the length of the cooler 1, so that the gear 31 can be arranged at the end of the connecting member 2, and the gear 31 will not block the cooler 1, and the influence on the cooling effect is small.

[0036] like Figure 5 As shown, further, the diameter of the gear 31 is greater than the thickness of the cooler 1, and the gear 31 is fixed to the connecting member 2 by the first fastener 4. The larger diameter gear 31 provides an installation position for the first fastener 4, so that the first fastener 4 will not interfere with the cooler 1. In this embodiment, the first fastener 4 is a bolt connection pair.

[0037] like Figure 5 As shown, the connecting member 2 includes a bottom plate 21 and a side plate 22, the side plate 22 is arranged at the end of the bottom plate 21, and the first fastener 4 fixes the gear 31 to the side plate 22 along the axial direction of the gear 31. By providing the side plate 22, the end of the connecting member 2 can abut against the surface of the gear 31, so that the first fastener 4 can fix the gear 31.

[0038] In this embodiment, four first fasteners 4 are provided on the gear 31. Two first fasteners 4 are provided on one side of the gear 31, and two first fasteners 4 are also provided on the other side opposite to the gear 31, thereby achieving a firm fixation of the gear 31. Accordingly, the number of the connecting members 2 is two, and the two connecting members 2 are respectively provided on both sides of the surface cooler 1.

[0039] The number of the first fasteners 4 should be at least two, and the two first fasteners 4 need to be symmetrically arranged about the center of the gear 31 to achieve good fixation of the gear 31 .

[0040] like Figure 5 As shown, the air conditioning unit further includes a second fastener 5, which passes through the bottom plate 21 and is connected to the cooler 1. The bottom plate 21 can abut against the surface of the cooler 1, so that the second fastener 5 can fix the connecting member 2 on the cooler 1. In this embodiment, the second fastener 5 is a screw.

[0041] like Figure 1 As shown, gears 31 are provided at both ends of the connecting member 2. Accordingly, two racks 32 and two driving members 33 can also be provided, so that both ends of the cooler 1 can rotate, so that the cooler 1 can rotate more smoothly.

[0042] like Figure 2 As shown, the rotating mechanism 3 further includes a slide groove 34, and the rack 32 is arranged in the slide groove 34 to reduce the resistance when the rack 32 moves, so that the surface cooler 1 can rotate more smoothly.

[0043] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
