Description

Technical Field

[0001] This utility model relates to the field of air conditioners, and in particular to a fresh air module for air conditioning equipment and an air conditioning equipment having the same. Background Technology

[0002] In related technologies, the indoor unit of an air conditioner is equipped with a fresh air module. The centrifugal fan inside the fresh air module and the cross-flow fan of the whole unit are coaxially designed and driven by the same motor. Since the coaxial drive determines the rotation axis of the centrifugal fan and the cross-flow fan, it is not conducive to the volute profile layout of the centrifugal fan in the fresh air module. If the volute adopts a conventional air outlet curve, the fresh air outlet will face the rear of the whole unit. The rear of the indoor unit is usually the ceiling or wall, which is not conducive to the diffusion of fresh air and is prone to problems such as condensation on the wall. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] In related technologies, the indoor unit of an air conditioner is equipped with a fresh air module. The centrifugal fan inside the fresh air module and the cross-flow fan of the whole unit are coaxially designed and driven by the same motor. Since the coaxial drive determines the rotation axis of the centrifugal fan and the cross-flow fan, it is not conducive to the volute profile layout of the centrifugal fan in the fresh air module. If the volute adopts a conventional air outlet curve, the fresh air outlet will face the rear of the whole unit. The rear of the indoor unit is usually the ceiling or wall, which is not conducive to the diffusion of fresh air and is prone to problems such as condensation on the wall.

[0034] The following is for reference. Figures 1-3 This invention describes a fresh air module 1 for an air conditioning device according to an embodiment of the present invention.

[0035] like Figure 3 As shown, the fresh air module 1 for an air conditioning device according to this utility model includes: a housing 10, an air outlet housing 20, and a fan 30. The housing 10 has an internal accommodating space 10a. The air outlet housing 20 is disposed in the housing 10 and has at least one air outlet channel 20a communicating with the accommodating space 10a. The air outlet housing 20 also has an air outlet 20c communicating with the air outlet channel 20a. At least a portion of the air outlet channel 20a connected to the air outlet 20c is configured as a straight channel 20b extending perpendicular to the horizontal direction. The fan 30 is rotatably disposed in the accommodating space 10a and adapted to drive airflow toward the air outlet 20c. Specifically, the fresh air module 1 can be used to introduce fresh air into an air conditioning device, and the fan 30 operates to drive airflow toward the air outlet 20c. Understandably, since at least one surface of the air conditioning equipment in the horizontal direction is generally directly opposite the wall, to prevent fresh air from being discharged towards the wall, the portion of the air outlet shell 20 near the air outlet 20c can be designed as a straight channel 20b extending perpendicular to the horizontal direction. This guides the fresh air to be discharged perpendicular to the horizontal direction, preventing condensation and facilitating the discharge and diffusion of fresh air. Furthermore, the impeller 30 is generally a centrifugal impeller with axial air intake and radial air discharge. When the impeller 30 rotates within the receiving space 10a, it drives the fresh air within the receiving space 10a to move centrifugally towards the air outlet 20c. To prevent the air outlet shell 20 from obstructing the air outlet 20c, i.e., to prevent the air outlet shell 20 from affecting the fresh air output, it is preferable to design the portion of the air outlet shell 20 near the air outlet 20c as a straight channel 20b extending perpendicular to the horizontal direction, thus facilitating the diffusion and discharge of fresh air.

[0036] According to the present invention, the fresh air module 1 for air conditioning equipment has the part of the air outlet shell 20 near the air outlet 20c designed as a straight channel 20b extending perpendicularly to the horizontal direction, so as to guide the fresh air to be discharged perpendicularly to the horizontal direction. This can prevent the air outlet shell 20 from blocking the air outlet 20c and prevent the fresh air from being discharged towards the wall, thereby avoiding fresh air condensation and facilitating the discharge and diffusion of fresh air, thus improving the user experience.

[0037] According to some embodiments of this utility model, such as Figure 3 As shown, the two walls of the air outlet casing 20 facing the impeller 30 in the rotation direction are a first wall 21 and a second wall 22, which are arranged sequentially in the rotation direction of the impeller 30. The first wall 21 and the second wall 22 are configured such that the radial distance between them and the impeller 30 gradually increases in the direction towards the air outlet 20c. At least a portion of the first wall 21 and the second wall 22 that connects to the air outlet 20c extends perpendicularly to the horizontal direction. Here, the first wall 21 is generally used to guide fresh air towards the air outlet 20c, and the second wall 22 is generally used to change the direction of fresh air flow within the accommodating space 10a, causing fresh air to flow towards the air outlet channel 20a. Both the first wall 21 and the second wall 22 have the effect of guiding fresh air towards the air outlet 20c. As the impeller 30 rotates, it causes the fresh air within the containment space 10a to undergo centrifugal motion. Therefore, the first wall 21 and the second wall 22 of the outlet casing 20, which face each other in the direction of the impeller 30's rotation, gradually increase in radial distance from the impeller 30 in the direction towards the outlet 20c, forming an involute outlet channel 20a to achieve the outlet and diffusion of fresh air. More specifically, at least the portions of the first wall 21 and the second wall 22 that connect to the outlet 20c extend perpendicularly to the horizontal direction, forming two walls of the straight channel 20b in the direction of the impeller 30's rotation, thereby guiding the fresh air to be outleted perpendicularly to the horizontal direction.

[0038] According to some embodiments of this utility model, such as Figure 3 As shown, at least a portion of the second wall 22 facing the receiving space 10a is inclined toward the first wall 21 to form a volute tongue segment 221. The volute tongue segment 221 extends toward the receiving space 10a, which can extend the length of the air outlet duct 20a, thereby increasing the fresh air volume entering the air outlet duct 20a, and further increasing the fresh air volume discharged from the air outlet 20c.

[0039] Here, since the volute tongue section 221 is located at the position with the largest airflow in the entire fresh air module 1, if the length of the volute tongue section 221 is small, the second wall 22 will have to forcibly change the direction of the fresh air flow in the accommodating space 10a, which will cause a serious condensation problem and reduce the fresh air volume. Therefore, in some embodiments, the length of the volute tongue section 221 is a, and satisfies: a≥5mm, so as to change the direction of the fresh air flow in the accommodating space 10a more smoothly and naturally, so that the fresh air flows towards the air outlet channel 20a.

[0040] According to some embodiments of this utility model, such as Figure 3As shown, the air outlet housing 20 is configured as a plurality of units spaced apart in the rotation direction of the impeller 30. Specifically, since there are multiple air outlet housings 20, there are also multiple air outlets 20c. Multiple air outlets 20c can reduce the air volume of a single air outlet 20c and increase the total air volume, thereby reducing the wind noise of a single air outlet 20c while increasing the total air volume. Furthermore, the multiple air outlet housings 20 are spaced apart in the rotation direction of the impeller 30 so that multiple air outlet channels 20a are spaced apart in the rotation direction of the impeller 30. When the impeller 30 is working, the multiple air outlet channels 20a can respectively obtain fresh air from different positions within the accommodating space 10a, thereby increasing the air volume of the fresh air module 1 and optimizing the air outlet effect of the fresh air module 1.

[0041] According to some embodiments of this utility model, such as Figure 1 , Figure 3 As shown, the air outlet housing 20 includes at least a first air outlet housing 201 and a second air outlet housing 202 arranged sequentially in the rotation direction of the impeller 30. The first wall 21 of the second air outlet housing 202 is inclined towards the second wall 22 of the first air outlet housing 201, and at least a portion of the wall surface of the second air outlet housing 202 facing the receiving space 10a is inclined towards the second wall 22 of the first air outlet housing 201. The end of the second air outlet housing 202 located in the receiving space 10a is connected to the end of the first air outlet housing 201 located in the receiving space 10a. This allows the second wall 22 of the first air outlet housing 201 to guide a portion of the fresh air to flow into the air outlet channel 20a of the first air outlet housing 201. Then, the first wall 21 of the second air outlet housing 202 can immediately guide the fresh air that has not yet entered the air outlet channel 20a of the first air outlet housing 201 into the air outlet channel 20a of the second air outlet housing 202, thereby improving the air outlet efficiency of the fresh air module 1 and optimizing the air outlet effect of the fresh air module 1. Furthermore, at least a portion of the first wall 21 of the second air outlet housing 202 is inclined toward the second wall 22 of the first air outlet housing 201 to enlarge the air duct inlet of the air outlet channel 20a of the second air outlet housing 202, increase the air volume entering the air outlet channel 20a of the second air outlet housing 202, reduce the wind resistance of the second air outlet housing 202 to fresh air, and reduce the generation of wind noise.

[0042] According to some embodiments of this utility model, such as Figure 3As shown, the housing 10 is disposed at the bottom of the air outlet housing 20, and the top of the air outlet housing 20 has an air outlet 20c suitable for airflow towards the top. The bottom of the housing 10 has an exhaust vent 10b communicating with the receiving space 10a. The exhaust vent 10b and the air outlet 20c have different airflow directions. Specifically, the exhaust vent 10b and the air outlet 20c have different airflow directions to achieve dispersed airflow, allowing fresh air to permeate the room. The air outlet 20c can be disposed at the top of the fresh air module 1 to airflow towards the top of the fresh air module 1, while the exhaust vent 10b can be disposed at the bottom of the fresh air module 1 to airflow towards the bottom and / or front of the fresh air module 1. Furthermore, the exhaust vent 10b is located at the bottom of the fresh air module 1, so the user feels a noticeable breeze during fresh air exchange. The air outlet 20c is located at the top of the fresh air module 1, so imperceptible fresh air exchange can be achieved. The fresh air module 1 designed according to this utility model can be applied in different scenarios. For example, when a user needs to feel the fresh air, the exhaust vent 10b at the bottom can be opened to meet the user's needs while achieving fresh air exchange; when a large temperature difference between indoors and outdoors is detected, the exhaust vent 10b at the bottom can be closed to prevent the fresh air blown by the exhaust vent 10b from blowing directly on the user, so that the fresh air is only discharged from the air outlet 20c at the top, so as to achieve fresh air exchange while avoiding user discomfort due to temperature difference and improving the user experience.

[0043] According to some embodiments of this utility model, such as Figure 3 As shown, at least a portion of the inner wall of the housing 10 is a guide surface 11, which is connected to the exhaust port 10b. The guide surface 11 is configured such that the radial distance between it and the impeller 30 gradually increases in the direction toward the exhaust port 10b. Specifically, the guide surface 11 has the effect of guiding fresh air toward the exhaust port 10b. In the rotation direction of the impeller 30, the guide surface 11 is configured such that the radial distance between it and the impeller 30 gradually increases in the direction toward the exhaust port 10b, thereby forming an opening air outlet channel 20a to realize the outlet and diffusion of fresh air.

[0044] Furthermore, the exhaust vent 10b is suitable for discharging air towards the front or bottom. The exhaust vent 10b can discharge air towards the front, the bottom, or both simultaneously. When the exhaust vent 10b discharges air towards the front of the housing 10, the visual effect of the airflow and the user experience are optimal. The air outlet 20c on the upper side and the exhaust vent 10b on the lower side of the fresh air module 1 can quickly replenish fresh air to fill the room, meeting the multi-directional airflow requirements of the fresh air module.

[0045] The air conditioning device according to this utility model is briefly described below.

[0046] The air conditioning device according to this utility model includes the fresh air module 1 for air conditioning devices described in any of the above embodiments. Since the air conditioning device according to this utility model is equipped with the fresh air module 1 for air conditioning devices described in the above embodiments, the user experience of the air conditioning device is better.

[0047] In summary, the fresh air module 1 for air conditioning equipment according to this utility model designs the part of the air outlet shell 20 near the air outlet 20c as a straight channel 20b extending perpendicularly to the horizontal direction, so as to guide the fresh air to be discharged perpendicularly to the horizontal direction. This can prevent the air outlet shell 20 from blocking the air outlet 20c and prevent the fresh air from being discharged towards the wall, thereby avoiding fresh air condensation and facilitating the discharge and diffusion of fresh air, thus improving the user experience.
