Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air supply mechanism, an indoor unit and an air conditioner. Background Technology

[0002] Split-type air conditioners are an important part of the commonly used air conditioner market. Among them, cabinet-type air conditioners are an important branch of split-type air conditioners, often used in family living rooms and small offices. Cabinet-type air conditioners have advantages such as high power and strong airflow.

[0003] Conventional air conditioning cabinet units have a maximum air delivery distance of only about 10m. For large spaces such as integrated living, dining and kitchen rooms, large conference rooms, and restaurants, the length far exceeds 10m. Traditional cabinet units cannot meet the requirements for air delivery distance. Some models increase the air delivery length by adding fans, but this also increases manufacturing costs. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide an air supply mechanism, an indoor unit, and an air conditioner, aiming to improve the technical problem of short air supply distance in existing cabinet air conditioners.

[0005] An embodiment of this utility model provides an air supply mechanism disposed at the air outlet of an air conditioner, including a plurality of guide portions spaced apart from each other along the width direction of the air outlet, the guide portions being disposed along the length direction of the air outlet, a first airflow channel being formed between adjacent guide portions, the guide portions being configured to form a first acceleration section in at least a portion of the first airflow channel, the cross-sectional area of ​​the first acceleration section gradually decreasing along the direction from the inlet end of the first airflow channel toward the outlet end of the first airflow channel.

[0006] In some embodiments of this utility model, a second airflow channel is provided on the guide portion.

[0007] In some embodiments of this utility model, the flow guide includes a first flow guide and a second flow guide disposed opposite to each other, and the first flow guide and the second flow guide are spaced apart to form the flow guide having the second airflow channel.

[0008] In some embodiments of this utility model, the second airflow channel is configured to have a second acceleration section, the cross-sectional area of ​​which gradually decreases along the direction from the inlet end of the second airflow channel toward the outlet end of the second airflow channel.

[0009] In some embodiments of this utility model, the first airflow channel includes a first acceleration section and a throat section that are sequentially connected from the inlet end to the outlet end of the first airflow channel. The cross-sectional area of ​​the throat section is consistent with the cross-sectional area at the outlet of the first acceleration section, and the lengths of the first acceleration section and the throat section are the same.

[0010] In some embodiments of this utility model, the first airflow channel further includes an expansion section, which is connected to the end of the throat section away from the first acceleration section. The cross-sectional area of ​​the expansion section gradually increases from the end of the expansion section near the throat section to the end of the expansion section away from the throat section. The first acceleration section, the throat section, and the expansion section have the same length.

[0011] In some embodiments of this utility model, the air supply mechanism includes a first connector and a second connector, and a plurality of the air guides are connected between the first connector and the second connector.

[0012] In some embodiments of this utility model, an indoor unit is also provided, including the aforementioned air supply mechanism.

[0013] In some embodiments of this utility model, the air supply mechanism is rotatably disposed in the indoor unit so that the indoor unit can switch between a long-distance air supply mode and a regular air supply mode. When the indoor unit is in the long-distance air supply mode, the air supply mechanism is located at the air outlet of the indoor unit; when the indoor unit is in the regular air supply mode, the air supply mechanism rotates to the inside of the indoor unit to move away from the air outlet of the indoor unit.

[0014] In some embodiments of this utility model, this utility model also provides an air conditioner, which includes the above-mentioned indoor unit or the above-mentioned air supply mechanism.

[0015] An embodiment of this utility model provides an air supply mechanism, an indoor unit, and an air conditioner. The air supply mechanism is disposed at the air outlet of the air conditioner and forms a first airflow channel through adjacent guide sections at intervals. The guide sections are configured to form a first acceleration section in at least a portion of the first airflow channel. By gradually reducing the cross-sectional area of ​​the first acceleration section along the air outlet direction, the airflow velocity is increased after passing through the first acceleration section, thereby increasing the air supply distance of the air conditioner.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0028] like Figures 1-6 As shown, this utility model provides an air supply mechanism 10, which is disposed at the air outlet of an air conditioner. The air supply mechanism 10 includes a plurality of guide portions 200 spaced apart from each other along the width direction of the air outlet. The guide portions 200 are arranged along the width direction of the air outlet. A first airflow channel 100 is formed between adjacent guide portions 200. The guide portions 200 are configured to form a first acceleration section 110 in at least a portion of the first airflow channel 100. The cross-sectional area of ​​the first acceleration section 110 gradually decreases from the inlet end of the first airflow channel 100 toward the outlet end of the first airflow channel 100.

[0029] The multiple guide sections 200 can be arranged at equal intervals, that is, the width of the first airflow channel 100 formed is the same; the multiple guide sections 200 can also be arranged at non-equal intervals, that is, the width of the first airflow channel 100 formed is different.

[0030] The cross-sectional area of ​​the first acceleration section 110 is the airflow cross-sectional area. The cross-sectional area of ​​the first acceleration section 110 gradually decreases along the direction from the inlet end of the first airflow channel 100 to the outlet end of the first airflow channel 100. That is, the airflow cross-sectional area of ​​the first acceleration section 110 gradually decreases along the direction from the air inlet side to the air outlet side. When the airflow passes through the first acceleration section 110, the airflow velocity will increase due to the decrease in the cross-sectional area.

[0031] That is, the air supply mechanism 10 is set at the air outlet of the air conditioner, and a first airflow channel 100 is formed by adjacent guide sections 200 at intervals. The guide sections 200 are configured to form a first acceleration section 110 in at least a part of the first airflow channel 100. By gradually reducing the cross-sectional area of ​​the first acceleration section 110 along the air outlet direction, the airflow velocity is increased after passing through the first acceleration section 110, thereby increasing the air supply distance of the air conditioner.

[0032] In some embodiments, the guide portion 200 is provided with a second airflow channel 210.

[0033] The second airflow channel 210 is located on the guide section 200, allowing the airflow on the windward side of the air supply mechanism 10 to pass through the second airflow channel 210 and flow through the leeward side of the air supply mechanism 10.

[0034] In this embodiment, the air supply mechanism 10 is equivalent to having a first airflow channel 100 and a second airflow channel 210, with a second airflow channel 210 provided between adjacent first airflow channels 100.

[0035] The first airflow channel 100 is used to accelerate the airflow, and the second airflow channel 210 can be used for normal airflow, such as a channel structure with a constant cross-sectional area, or the second airflow channel 210 can also be used to accelerate the airflow, such as a channel structure with a cross-sectional area that gradually decreases along the air outlet direction.

[0036] It is understandable that the second airflow channel 210 is provided on the guide section 200 to ensure the air volume and to ensure smooth airflow under low temperature conditions, thereby preventing condensation from occurring on the air supply mechanism 10 due to prolonged contact with low temperature airflow.

[0037] In some embodiments, the flow guide 200 includes a first flow guide 201 and a second flow guide 202 disposed opposite to each other, and the first flow guide 201 and the second flow guide 202 are spaced apart to form a flow guide 200 having a second airflow channel 210.

[0038] That is, by setting the first guide member 201 and the second guide member 202 at intervals, the two are arranged to form a second airflow channel 210. At the same time, the first guide member 201 of each guide section 200 cooperates with the second guide member 202 of the adjacent guide section 200 to form a first airflow channel 100.

[0039] Generally, the first guide member 201 and the second guide member 202 are symmetrical to each other, so that the first airflow channel 100 is also an axisymmetric structure.

[0040] In some embodiments, the second airflow channel 210 is configured to have a second acceleration section 211, the cross-sectional area of ​​which gradually decreases along the direction from the inlet end of the second airflow channel 210 toward the outlet end of the second airflow channel 210.

[0041] That is, by accelerating the airflow through the second airflow channel 210, the air delivery distance of the air conditioner can be further increased while ensuring that the air volume at the air outlet remains unchanged.

[0042] In some embodiments, the cross-sectional area of ​​the second airflow channel 210 remains unchanged, allowing the airflow to pass through the second airflow channel 210 at its original velocity.

[0043] In some embodiments, the first airflow channel 100 includes a first acceleration section 110 and a throat section 120 that are sequentially connected from the inlet end of the first airflow channel 100 to the outlet end of the first airflow channel 100. The cross-sectional area of ​​the throat section 120 is consistent with the cross-sectional area at the outlet of the first acceleration section 110, and the lengths of the first acceleration section 110 and the throat section 120 are the same.

[0044] In some embodiments, the first airflow passage 100 further includes an expansion section 130, which is connected to the end of the throat section 120 away from the first acceleration section 110. The cross-sectional area of ​​the expansion section 130 gradually increases from the end of the expansion section 130 near the throat section 120 to the end of the expansion section 130 away from the throat section 120. The first acceleration section 110, the throat section 120 and the expansion section 130 have the same length.

[0045] The cross-sectional area at the inlet of the first acceleration section 110 is L, the cross-sectional area at the throat section 120 is K, and the cross-sectional area at the outlet of the expansion section 130 is M. L is greater than M, and M is greater than K. That is, by setting it upward, the first airflow channel 100 is made into a Venturi tube, thereby utilizing the Venturi effect to increase the airflow velocity without affecting the airflow volume, and thus increase the air delivery distance.

[0046] In some embodiments, the air supply mechanism 10 includes a first connector and a second connector, and a plurality of air guides 200 are connected between the first connector and the second connector.

[0047] The first connector and the second connector are both arranged along the width direction of the air outlet (or the air outlet of the indoor unit) of the air conditioner. One end of the guide part 200 is connected to the first connector, and the other end of the guide part 200 is connected to the second connector. Through the first connector and the second connector, the multiple air supply mechanisms 10 are integrated into a whole, and can move between multiple positions under the drive of the drive mechanism, thereby realizing the switching of the air conditioner between multiple air supply modes.

[0048] In some embodiments, the present invention also provides an indoor unit, which includes the above-mentioned air supply mechanism 10. Since the indoor unit includes the above-mentioned air supply mechanism 10, that is, includes some or all of the embodiments of the above-mentioned air supply mechanism 10, the air conditioner has the beneficial effects of some or all of the embodiments of the above-mentioned air supply mechanism 10, which will not be described in detail here.

[0049] In some embodiments, the air supply mechanism 10 is rotatably disposed in the indoor unit so that the indoor unit can switch between a long-distance air supply mode and a regular air supply mode. When the indoor unit is in the long-distance air supply mode, the air supply mechanism 10 is located at the air outlet of the indoor unit; when the indoor unit is in the regular air supply mode, the air supply mechanism 10 rotates to the inside of the indoor unit to move away from the air outlet of the indoor unit.

[0050] Specifically, for example, a rack is provided on the first connecting member, and the gear meshes with the rack to drive the air supply mechanism 10 to move between the first position and the second position; when the indoor unit switches to the long-distance air supply mode, when the air supply mechanism 10 is in the first position, the air supply mechanism 10 is located at the air outlet of the indoor unit, which can accelerate the airflow at the air outlet of the indoor unit so that it can blow further; when the indoor unit switches to the normal air supply mode, the air supply mechanism 10 moves to the second position, away from the air outlet of the indoor unit, so that the indoor unit performs normal air supply.

[0051] In some embodiments, the present invention also provides an air conditioner that includes the above-described indoor unit. Since the indoor unit has the above-described air supply mechanism 10, that is, includes some or all embodiments of the above-described air supply mechanism 10, the corresponding air conditioner has the beneficial effects of some or all embodiments of the above-described air supply mechanism 10.

[0052] In some embodiments, the present invention also provides an air conditioner that includes the above-mentioned air supply mechanism 10. Since the air conditioner includes the above-mentioned air supply mechanism 10, that is, includes some or all of the embodiments of the above-mentioned air supply mechanism 10, the air conditioner has the beneficial effects of some or all of the embodiments of the above-mentioned air supply mechanism 10, which will not be described in detail here.

[0053] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
