Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a dual-temperature zone air conditioning unit with a flow guiding structure. Background Technology

[0002] With the rapid development of new energy vehicles, the design of air conditioning units that provide functions such as cooling, heating, defrosting, and dehumidification is facing severe challenges. During the development of air conditioning units, it is necessary to minimize resistance within a limited space to increase airflow, reduce noise, and achieve the temperature linearity requirements that meet passenger comfort. Therefore, a reasonable structural design is crucial. However, currently, for dual-zone air conditioning units, the positions of the front airflow, foot airflow, and defrosting air outlets are roughly the same. Current air conditioning unit designs, constrained by space limitations, often result in airflow that barely meets the required level. It is impossible to increase resistance to ensure that the temperature difference between the upper and lower parts of the air conditioning unit in both the front / foot airflow and foot defrosting modes meets the requirements.

[0003] Therefore, there is an urgent need to propose a dual-temperature zone air conditioning unit with a flow guiding structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-temperature zone air conditioning unit with a flow guiding structure, which solves the problems of insufficient air volume and poor temperature linearity caused by space limitations in existing air conditioning units, and realizes the improvement of air volume and reduction of noise in a limited space, while meeting the temperature difference requirements of different modes.

[0007] The housing and the warm air core are arranged vertically. The housing has a foot blowing outlet and a defrost outlet. The warm air core is fixedly connected to the housing.

[0008] The airflow guiding structure includes a foot-blowing damper, a sloping air guide plate, a temperature damper, two cold channels, and a hot channel. The foot-blowing damper is located above the foot-blowing air outlet and is rotatably connected to the housing. The sloping air guide plate is located between the foot-blowing air outlet and the warm air core, and the sloping air guide plate is set at an angle. The temperature damper is rotatably connected to the housing and is located on one side of the cold air inlet of the cold channel and the hot air inlet of the hot channel. The cold air inlet is rectangular and is used to guide the cold air to the foot-blowing air outlet. The hot air inlet is triangular and is set opposite to the air outlet of the warm air core. The hot channel is used to guide the hot air to the defrost air outlet.

[0009] Preferably, the thermal channel is triangular prism shaped.

[0010] Preferably, the housing is also provided with a surface air outlet, with the cold air outlet of the cold channel facing the surface air outlet and the hot air outlet of the hot channel facing the defrost air outlet.

[0011] As a preferred embodiment, the airflow guiding structure also includes a blowing damper, which is rotatably connected to the housing and is positioned opposite to the blowing air outlet.

[0012] As a preferred embodiment, the airflow guiding structure also includes a defrost damper, which is rotatably connected to the housing and is positioned opposite to the defrost air outlet.

[0013] As a preferred embodiment, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a door baffle structure, which includes a foot-blowing door baffle, a defrosting door baffle, and a face-blowing door baffle. The foot-blowing door baffle and the defrosting door baffle are both fixedly connected to the housing. The foot-blowing door baffle is set to correspond with the foot-blowing air damper, the defrosting door baffle is set to correspond with the defrosting air damper, and the face-blowing door baffle is set to correspond with the face-blowing air damper.

[0014] Preferably, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a door hinge structure, which includes a foot-blowing door hinge, a face-blowing door hinge, and a defrosting door hinge. The foot-blowing door is rotatably connected to the housing through the foot-blowing door hinge, the face-blowing door is rotatably connected to the housing through the face-blowing door hinge, and the defrosting door is rotatably connected to the housing through the defrosting door hinge.

[0015] Preferably, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a drive structure, the output end of which is connected to the air blowing door hinge, the foot blowing door hinge, and the defrost door hinge, respectively.

[0016] Preferably, the shell is symmetrically arranged along its thickness direction, and the face blowing damper, foot blowing damper, and defrosting damper are all symmetrically arranged and rotatably connected to the other side of the shell.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a dual-temperature zone air conditioning unit with a flow guiding structure, including a shell, a warm air core, and a flow guiding structure. The flow guiding structure includes a foot-blowing damper, a sloping air guide plate, a temperature damper, two cold channels, and a hot channel. In the face-blowing and foot-blowing mode, the hot air flow from the warm air core is mixed with the cold air flow to a certain extent under the guidance of the sloping air guide plate, improving the mixing efficiency, reducing the temperature difference between the face and the foot, and obtaining a suitable temperature at the foot-blowing air outlet. In the foot-blowing and defrosting mode, the hot air flow is guided to the defrosting air outlet through the hot channel, and the cold air flow is guided to the foot-blowing air outlet through the cold channel, reducing the amount of cold air at the defrosting air outlet and the amount of hot air at the foot-blowing air outlet. Furthermore, the hot air inlet is set to a triangular shape, and the cold air inlet is set to a rectangle. By changing the position of the temperature damper, the air intake of the cold and hot channels can be controlled without significantly increasing the resistance, thereby ensuring that the foot-blowing air outlet and the defrosting air outlet obtain a reasonable outlet temperature. By setting a sloping air guide plate in the hot runner behind the warm air core, combined with the specific arrangement of the foot air damper and the addition of hot and cold channels, the problem of insufficient air volume and poor temperature linearity caused by space limitations in existing air conditioning units is solved. This achieves increased air volume and reduced noise in a limited space, while meeting the temperature difference requirements of different modes, thus improving the overall performance of the dual-temperature zone air conditioning unit.

[0034] This embodiment provides a dual-temperature zone air conditioning unit with a flow guiding structure, which solves the problems of insufficient air volume and poor temperature linearity caused by space limitations in existing air conditioning units. It achieves increased air volume and reduced noise in a limited space, and meets the temperature difference requirements of different modes.

[0035] Specifically, such as Figures 1 to 5 As shown, a dual-temperature zone air conditioning unit with a flow guiding structure includes a shell 100, a warm air core 200, and a flow guiding structure. The flow guiding structure includes a foot-blowing damper 310, an inclined air guide plate 320, two cold channels 340, and a hot channel 350. The shell 100 is placed vertically, and a foot-blowing air outlet 110 and a defrosting air outlet 120 are provided on the shell 100. The warm air core 200 is fixedly connected to the shell 100. The airflow guiding structure includes a foot-blowing damper 310, an inclined air guide plate 320, a temperature damper 330, two cold channels 340, and a hot channel 350. The foot-blowing damper 310 is located above the foot-blowing outlet 110 and is rotatably connected to the housing 100. The inclined air guide plate 320 is located between the foot-blowing outlet 110 and the warm air core 200, and is inclined. The temperature damper 330 is rotatably connected to the housing 100 and is located between the cold air inlet 341 of the cold channel 340 and the hot channel 350. On one side of the hot air inlet 351 of the 50, the cold air inlet 341 is rectangular. The cold channel 340 is used to guide the cold air to the foot blowing air outlet 110. The hot air inlet 351 is triangular and is set opposite to the air outlet of the warm air core 200. The hot channel 350 is used to guide the hot air to the defrost air outlet 120. By changing the position of the temperature damper 330, the air intake of the cold channel 340 and the hot channel 350 can be controlled, and the temperature of the defrost air outlet 120 and the foot blowing air outlet 110 can be adjusted to meet the temperature linearity requirements of different modes.

[0036] In the face and foot blowing mode, the hot air flow from the warm air core 200 is mixed with the cold air flow to a certain extent under the guidance of the inclined air guide plate 320, which improves the mixing efficiency, reduces the temperature difference between the face and feet, and ensures that the foot blowing outlet 110 reaches a suitable temperature. In the foot blowing defrost mode, the hot air flow is guided to the defrost outlet 120 through the hot channel 350, and the cold air flow is guided to the foot blowing outlet 110 through the cold channel 340, which reduces the amount of cold air at the defrost outlet 120 and the amount of hot air at the foot blowing outlet 110. The shape of the hot inlet is set to triangular, and the cold air inlet 341 is set to rectangular. By changing the position of the temperature damper 330, the air intake of the cold channel 340 and the hot channel 350 can be controlled without significantly increasing the resistance, so that the foot blowing outlet 110 and the defrost outlet 120 can obtain a reasonable outlet temperature. By setting an inclined air guide plate 320 in the hot runner after the warm air core 200, combined with the specific arrangement of the foot air damper 310 and the addition of hot passage 350 and cold passage 340, the problem of insufficient air volume and poor temperature linearity caused by space limitations in existing air conditioning units is solved. This achieves increased air volume and reduced noise in a limited space, while meeting the temperature difference requirements of different modes, thus improving the overall performance of the dual-temperature zone air conditioning unit.

[0037] It should be noted that the cold air inlet 341 can also be designed in the shape of a circle, ellipse or polygon, as long as it can work with the temperature damper 330 to effectively control the air volume of the cold aisle 340 and does not significantly increase the resistance. The specific design can be determined according to the internal space layout and airflow control requirements of the air conditioning unit.

[0038] Furthermore, the hot aisle 350 is triangular prism-shaped to reduce airflow loss. At the same time, it is combined with a triangular inlet to facilitate control of the airflow in the hot aisle 350 at different positions of the temperature damper 330, ensuring that the outlet air temperature of the defrost outlet 120 is reasonable.

[0039] Furthermore, both the cold aisle 340 and the hot aisle 350 are fixedly connected to the housing 100 to fix the cold aisle 340 and the hot aisle 350, so as to avoid the instability of the flow direction of cold and hot air due to the shaking of the cold aisle 340 and the hot aisle 350, which would affect the temperature of the foot blowing outlet 110 and the defrost outlet 120.

[0040] Furthermore, the housing 100 also has a face-blowing air outlet 130. After adding the hot channel 350, the face-to-foot temperature difference in the face-blowing and foot-blowing modes already meets the requirements. Generally, adding a cold channel 340 would result in an excessively small face-to-foot temperature difference in the face-blowing and foot-blowing modes. Therefore, the cold air outlet 342 of the cold channel 340 faces the face-blowing air outlet 130 to avoid adversely affecting the face-to-foot temperature difference in the face-blowing and foot-blowing modes. This ensures that the added cold channel 340 has virtually no impact on the face-to-foot temperature difference in the face-blowing and foot-blowing modes. In the foot-blowing defrosting mode, the defrosting air outlet 120 has a lower temperature. Therefore, the hot air outlet 352 of the hot channel 350 faces the defrosting air outlet 120 to specifically guide the heat flow to the defrosting area, increasing the temperature of the defrosting air outlet 120 in the foot-blowing defrosting mode, reducing the temperature difference with the foot-blowing air outlet 110, and meeting the temperature requirements of this mode. It should be noted that, for the foot defrosting mode, although the cold aisle 340 outlet faces the face outlet, the face air damper 360 is closed in this mode, and the cold airflow in the cold aisle 340 will still enter the foot air outlet 110 through the face air damper 360.

[0041] Optionally, the airflow guiding structure also includes a face blowing damper 360, which is rotatably connected to the housing 100. The face blowing damper 360 is arranged opposite to the face blowing air outlet 130. By rotating and adjusting the opening degree of the face blowing air outlet 130, the airflow to the face area is controlled to meet the air outlet requirements in face blowing, foot blowing, and other modes.

[0042] Optionally, the airflow guiding structure also includes a defrost damper 370, which is rotatably connected to the housing 100. The defrost damper 370 is positioned opposite to the defrost outlet 120. By rotating the defrost outlet 120, the opening degree of the defrost outlet 120 is adjusted to control the airflow to the defrost area, so as to meet the defrosting requirements in modes such as foot defrosting.

[0043] Optionally, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a door stop structure, which includes a foot-blowing door stop 410, a defrosting door stop 420, and a face-blowing door stop 430. The foot-blowing door stop 410, defrosting door stop 420, and face-blowing door stop 430 are all fixedly connected to the housing 100. The foot-blowing door stop 410 is correspondingly arranged with the foot-blowing damper 310, and the foot-blowing door stop 410 limits the movement range and position of the foot-blowing damper 310 from different directions, assisting the temperature damper 330. Precisely control the airflow and flow rate of the foot-blowing air outlet 110; the defrost door 420 and the defrost damper 370 are correspondingly set, and the defrost door 420 limits the movement range and position of the defrost damper 370 from different directions; the auxiliary temperature damper 330 precisely controls the airflow and flow rate of the defrost air outlet 120; the face-blowing door 430 and the face-blowing damper 360 are correspondingly set, and the face-blowing door 430 limits the movement range and position of the face-blowing damper 360 from different directions.

[0044] Furthermore, such as Figure 6As shown, the foot blowing door 410, the foot blowing damper 310, and the side wall of the housing 100 are arranged in sequence at intervals, leaving room for the foot blowing damper 310 to rotate, avoiding movement interference, while ensuring smooth airflow and ensuring precise control of the foot blowing outlet 110 by the temperature damper 330.

[0045] Optionally, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a door hinge structure, which includes a foot-blowing door hinge 510, a face-blowing door hinge 520, and a defrost door hinge 530. The foot-blowing damper 310 is rotatably connected to the housing 100 via the foot-blowing door hinge 510. The foot-blowing door hinge 510 can serve as a rotation fulcrum for the foot-blowing damper 310, allowing the foot-blowing damper 310 to rotate around it to adjust the opening degree of the foot-blowing air outlet 110, thereby controlling the airflow of the foot-blowing air outlet 110. The face-blowing damper 360 is connected to the housing 100 via the face-blowing door hinge 520. The blowing door shaft 520 is rotatably connected to the housing 100 via the blowing door shaft 530. The blowing door shaft 53 ...20 is rotatably connected to the housing 100 via the blowing door shaft 530. The blowing door shaft 520 is rotatably connected to the housing 100 via the blowing door shaft 530. The blowing door shaft 520 is rotatably connected to the housing 100 via the blowing door shaft 530. The blowing door shaft 520 is rotatably connected to the housing 100 via the blowing door shaft 530. The blowing door shaft 520 is rotatably connected to

[0046] Furthermore, the door hinge structure also includes a temperature door hinge 540, which can serve as a rotation fulcrum for the temperature damper 330, allowing the temperature damper 330 to rotate around it to adjust different positions of the temperature damper 330 and control the airflow entering the cold aisle 340 and the hot aisle 350.

[0047] Furthermore, the dual-temperature zone air conditioning unit with the airflow guiding structure also includes a drive structure. The output end of the drive structure is connected to the air blowing door shaft 520, the foot blowing door shaft 510 and the defrost door shaft 530 respectively, which can drive each air door to rotate around the corresponding door shaft, realize independent control of different air outlets, and meet the needs of multiple air outlet modes.

[0048] Optionally, along the thickness direction of the housing 100, the housing 100 is symmetrically arranged, and the face air damper 360, foot air damper 310 and defrost air damper 370 are all symmetrically arranged and rotatably connected to the other side of the housing 100 to adapt to the dual-temperature zone design, ensuring the uniformity and consistency of air outlet on both sides, and improving the overall performance of the dual-temperature zone air conditioning unit and passenger comfort.

[0049] The working process and principle of the dual-temperature zone air conditioning unit with a flow guiding structure provided in this embodiment are as follows:

[0050] like Figure 6As shown, when the foot-blowing damper 310 is fully open, the left end point of the foot-blowing damper 310 is located between the top end point of the inclined air guide plate 320 and the right side of the face-blowing gate 430 (i.e., Figure 6 As shown by the dashed line B), the foot blowing door shaft 510 is basically located at the lower side of the foot blowing door stop 410 and the middle position between the housing 100 (i.e., Figure 6 As shown by the dashed line C), the foot damper 310 is in a fully open state close to the airflow direction, and this damper arrangement method minimizes resistance.

[0051] As verified by experiments, such as Figures 7 to 8 As shown, the temperature linearity test results of the face blowing and foot blowing modes and the foot blowing and defrosting modes show that the design of the inclined baffle plate increases the air volume by about 2% compared with the conventional design; the design of the cold and hot aisles of 350 increases the air volume of the face blowing and defrosting modes by about 2% and the air volume of the foot blowing mode by about 3% compared with the conventional design. The temperature difference between the face and feet in the face blowing and foot blowing modes and the temperature difference between the feet and frost in the foot blowing and defrosting modes fully meet the requirements.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
