[0031] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0032] Reference below Figure 1-Figure 5 The air conditioner 100 according to the embodiment of the present application is described. The air conditioner 100 can be applied indoors and used for indoor heat exchange to adjust the indoor temperature.

[0033] Reference Figure 1-Figure 5 According to an embodiment of the present application, the air conditioner 100 includes: a shell 1 and an air outlet assembly 2, the air outlet assembly 2 is arranged in the shell 1, and the air outlet assembly 2 forms an air outlet channel 20, the air outlet channel 20 is connected between the fan assembly 4 and the air outlet 104 of the shell 1, and is used to guide the airflow to the air outlet 104.

[0034] Among them, a fan assembly 4 is arranged in the shell 1. When the fan assembly 4 is running, an airflow can be formed in the shell 1, and the air outlet side of the fan assembly 4 is connected to the air outlet assembly 2. Through the air outlet assembly 2, the airflow blown out by the fan assembly 4 can be further guided to the side of the air outlet 104.

[0035] like Figure 1 As shown, the air outlet channel 20 at least includes an air inlet section 201 and a drainage section 202, one end of the air inlet section 201 is connected to the air outlet side of the fan assembly 4, the airflow blown out by the fan assembly 4 can flow into the air inlet section 201, and the drainage section 202 is connected to the other end of the air inlet section 201. Among them, the connection area between the air inlet section 201 and the fan assembly 4 is larger than the connection area between the air inlet section 201 and the drainage section 202, so that negative pressure can be formed on one side of the drainage section 202.

[0036] Furthermore, the air outlet component 2 is provided with a guide port at the guide section 202, which is connected between the air outlet channel 20 and the air inlet structure of the shell 1, and the guide port is used to guide the indoor air into the air outlet channel 20, so that the indoor air is mixed with the heat exchange air in the air outlet channel 20, thereby accelerating the heat exchange of the indoor air and improving the heat exchange efficiency of the air conditioner 100.

[0037] It can be understood that since the connecting areas at both ends of the air inlet section 201 are different, that is, the connecting area of ​​the air inlet section 201 at the air inlet end is larger than the connecting area of ​​the air inlet section 201 at the air outlet end, the air flow velocity on the air outlet side is higher than the air flow velocity on the air inlet side. According to the Venturi effect (Venturi effect: a pressure reduction will occur near a high-speed flowing gas, thereby producing an adsorption effect), a pressure difference is formed at the drainage section 202 (that is, the gas flow velocity at the drainage section 202 is fast and the pressure is small), and the air at the drainage port will be drained into the drainage section 202 and mixed with the heat exchange air.

[0038] The air inlet is formed on the wall surface of the air outlet assembly 2, and the air inlet hole is used to connect the air inlet structure of the housing 1 with the air outlet passage 20. The indoor air entering the housing 1 through the air inlet structure can enter the air outlet passage 20 through the air inlet, so that the indoor air and the heat exchange air are mixed in the air outlet passage 20, which can speed up the indoor heat exchange efficiency and improve the air supply comfort of the air conditioner 100. At the same time, the air outlet assembly 2 is arranged in the housing 1, which has little effect on the appearance of the air conditioner 100.

[0039] In the air outlet assembly 2, the pressure difference formed at the wall surface in the area corresponding to the drainage section 202 has a good effect. Forming the drainage port at the wall surface corresponding to the drainage section 202 can ensure the drainage effect of the drainage port on the air.

[0040] It should be noted that, at present, the air outlet temperature of the air conditioner in cooling condition is relatively low, which affects the comfort of cooling air supply. In the related technology, the wind is dispersed by a microporous air guide structure or an additional air mixing device is set. Among them, although the wind can be dispersed by the microporous air guide structure to form an air supply state with no wind feeling or soft wind feeling, the wind resistance through the microporous air guide structure is large and the heat exchange efficiency is low; the method of setting up an additional air mixing device (such as: fan, etc.) will lead to an increase in the size and cost of the air conditioner, and affect the appearance of the air conditioner.

[0041] In the present application, by constructing the air inlet section 201 of the air outlet component 2 so that the air inlet area is larger than the air outlet area, a pressure difference can be formed at the guide section 202. The air located on the outside of the air outlet component 2 can enter the air outlet channel 20 through the guide port, and be mixed with the heat exchange air in the air outlet channel 20 and then discharged, thereby reducing the air outlet temperature of the air conditioner 100, improving the air supply comfort of the air conditioner 100, and accelerating the indoor heat exchange efficiency.

[0042] It is understandable that according to the principle of the Venturi effect, when the limited flow passes through the narrowing flow cross section (i.e., the connection between the air inlet section 201 and the drainage section 202 in the present application), the flow velocity of the fluid will increase, and from Bernoulli's principle, the increase in flow velocity is accompanied by a decrease in fluid pressure, so that the pressure in the drainage section 202 area of ​​the present application is reduced, and the air outlet channel 20 can use the pressure difference to absorb the air at the drainage port (located outside the air outlet component 2) and mix it with the heat exchange air in the air outlet channel 20 to achieve the purpose of mixing air and accelerate indoor air heat exchange. Compared with the above-mentioned prior art solutions, the air mixing method in the present application can improve the indoor heat exchange efficiency while ensuring the air outlet effect, and there is no need to add an additional air mixing device (such as a fan) to the air conditioner 100, which can reduce the impact on the appearance of the air conditioner 100.

[0043] like Figure 1 As shown, in some embodiments of the present application, a heat exchanger is also provided in the air conditioner 100. The heat exchanger is arranged in the shell 1 and is used to exchange heat with the air entering the shell 1 to form heat exchange air. The heat exchange air can form a fast-flowing airflow under the action of the fan assembly 4 to realize the air supply function of the air conditioner 100.

[0044] It should be noted that the housing 1 has an air inlet structure, and indoor air (i.e., air in the environment where the air conditioner 100 is located) can enter the housing 1 through the air inlet structure. The air inlet structure may include multiple air inlets, such as: a top air inlet 101, a front air inlet 102, a bottom air inlet 103, etc.

[0045] Reference Figure 2 , Figure 2 The middle arrow is a schematic diagram of the air flow direction in the housing 1. Among them, the top air inlet 101 is set at the top of the housing 1, and the air entering the housing 1 through the top air inlet 101 can flow to the side of the heat exchanger or to the guide port; the front air inlet 102 is set at the front wall of the housing 1, and the front air inlet 102 is located at the front wall near the air outlet component 2, and the air entering the housing 1 through the front air inlet 102 can flow to the guide port; the bottom air inlet 103 is set at the bottom wall of the housing 1, and the bottom air inlet 103 can be set at the bottom wall near the guide port, and the air entering the housing 1 through the bottom air inlet 103 can flow to the guide port.

[0046] like Figure 2 As shown, in some embodiments, an air induced draft channel 105 is provided in the shell 1, and the air induced draft channel 105 can be connected between the air induced port and the air inlet of the shell 1. The air entering the shell 1 through the air inlet flows into the air induced draft channel 105 and can further flow to the air induced port to achieve mixing of the indoor air and the heat exchange air, thereby preventing the air supply temperature of the air outlet 104 from being too low.

[0047] Reference Figure 2The housing 1 includes a face frame 11 and a panel 12, wherein the panel 12 is disposed at the front side of the face frame 11, and the above-mentioned air induction channel 105 is defined between the panel 12 and the front wall of the face frame 11. The air entering the face frame 11 through the air inlet on the housing 1 can flow into the air induction channel 105, and then flow into the air inlet after further flowing through the air induction channel 105.

[0048] In some specific embodiments, the face frame 11 is provided with a top air inlet 101, and the air entering the face frame 11 through the top air inlet 101 can flow into the air induction channel 105 from the front wall of the face frame 11. A connecting structure, such as a connecting hole, can be formed on the front wall of the face frame 11 to connect the inside of the face frame 11 with the air induction channel 105. Thus, the air entering the face frame 11 through the air inlet structure can flow into the air induction channel 105.

[0049] like Figure 1 As shown, in some embodiments of the present application, the air outlet assembly 2 includes a first air duct wall 21 and a second air duct wall 22 that are relatively arranged, an air outlet channel 20 is formed between the first air duct wall 21 and the second air duct wall 22, and at least one of the first air duct wall 21 and the second air duct wall 22 is provided with a drainage port.

[0050] Reference Figure 1 , Figure 2 and Figure 3 , the first air duct wall 21 and the second air duct wall 22 are both provided with drainage ports; Figure 4 , only the second air duct wall 22 is provided with a drainage port; Figure 5 , only the first air duct wall 21 is provided with a flow outlet. Among them, by providing a plurality of flow outlets, the flow area can be increased, and the mixing effect of the heat exchange air and the indoor air can be improved.

[0051] like Figure 3 As shown, in some embodiments of the present application, the air outlet assembly 2 further includes a guide member 3, which is disposed between the first air duct wall 21 and the second air duct wall 22. The guide member 3 can guide the flow direction of the airflow in the air outlet channel 20, and the guide member 3 located in the air outlet channel 20 can adjust the flow area of ​​the air outlet channel 20 in the flow direction, so that the flow area of ​​the air inlet section 201 adjacent to the guide section 202 can be constructed as a ventilation section that conforms to the Venturi effect principle through the guide member 3.

[0052] It should be noted that, in other embodiments, the air inlet section 201 can be constructed as a ventilation section suitable for the principle of the Venturi effect by adjusting the structure of the first air duct wall 21 and the second air duct wall 22 (such as: constructing the opening area of ​​the air inlet section 201 to be gradually tapered toward the side of the diversion section 202, etc.), and is not limited to the solution of setting a guide member 3 between the first air duct wall 21 and the second air duct wall 22 to change the connection position between the air inlet section 201 and the diversion section 202.

[0053] Reference Figure 3 In some embodiments of the present application, the guide member 3 includes a first guide portion 31, which is disposed in the air inlet section 201, and the first guide portion 31 is gradually expanded from the air inlet section 201 to the guide section 202 side, so as to gradually reduce the air inlet area of ​​the air inlet section 201 toward the guide section 202 side. In other words, the flow cross-sectional area at the air inlet section 201 can be adjusted by the guide member 3 located in the air outlet channel 20.

[0054] It can be understood that the first guide portion 31 is located at the air inlet section 201, and the cross-section of the first guide portion 31 gradually increases along the air supply direction, so that the air inlet area of ​​the air inlet section 201 gradually decreases toward the guide section 202 side, so that the air flow velocity flowing into the guide section 202 through the air inlet section 201 increases, so as to generate suction at the guide section 202 through the fast-flowing airflow, and introduce the air outside the air outlet channel 20 into the air outlet channel 20 through the guide port.

[0055] It should be noted that the air inlet area at the air inlet section 201 is defined by the air outlet assembly 2, that is, the first air duct wall 21, the second air duct wall 22 and the guide member 3. The air inlet section 201 defined by the first air duct wall 21 and the second air duct wall 22 can be configured to be arranged with equal spacing of opening sizes along the air supply direction, can also be configured to be gradually expanded along the air supply direction, and can also be configured to be gradually contracted along the air supply direction.

[0056] The “equal spacing” means that the distance between the part of the first air duct wall 21 and the part of the second air duct wall 22 used to define the air guide section is equal everywhere in the air supply direction; Figure 3 "Gradually expanding" means that the distance between the part of the first air duct wall 21 and the part of the second air duct wall 22 that define the air guide section gradually increases in the air supply direction. To ensure that the air inlet area of ​​the air inlet section 201 decreases in the air supply direction, the incremental size of the first air guide portion 31 needs to be greater than the incremental size between the first air duct wall 21 and the second air duct wall 22, so as to achieve a decreasing setting of the air inlet area of ​​the air inlet section 201 toward the guide section 202 side.

[0057] like Figure 1As shown, in some embodiments of the present application, the air outlet channel 20 also includes an air outlet section 203, the air outlet section 203 is connected to the guide section 202, and the air outlet end of the air outlet section 203 is connected to the air outlet 104 of the shell 1, and the air flow flowing out through the guide section 202 can flow into the air outlet section 203, and after flowing through the air outlet section 203, it can be further blown out through the air outlet 104.

[0058] It can be understood that the air outlet section 203 is located downstream of the induction section 202 in the air supply direction, so that the heat exchange air and the indoor air can be fully mixed in the air outlet section 203, ensuring the heat exchange effect between the heat exchange air and the indoor air, so that the heat exchange air mixed with the indoor air is transported to one side of the room, preventing the air supply temperature from being too low while improving the indoor heat exchange efficiency.

[0059] It should be noted that the air outlet channel 20 is a ventilation structure (i.e., a spatial structure) defined by the air outlet assembly 2 (e.g., the first air duct wall 21, the second air duct wall 22, and the guide member 3, etc.). Accordingly, the air outlet channel 20 is composed of three ventilation structures: an air inlet section 201, a guide section 202, and an air outlet section 203.

[0060] like Figure 3 As shown, in some embodiments of the present application, the guide member 3 also includes a second guide portion 32, which is arranged in the air outlet section 203, and the second guide portion 32 is arranged in a tapered shape from the guide section 202 to the side of the air outlet section 203 to gradually increase the air outlet area of ​​the air outlet section 203 toward the side of the air outlet section 203.

[0061] It is understandable that the second guide portion 32 is located at the air outlet section 203, and the cross-section of the second guide portion 32 gradually decreases along the air supply direction, so that the air outlet area of ​​the air outlet section 203 gradually increases toward the air outlet 104, so that the air flow speed decreases.

[0062] Among them, since the outlet area of ​​the air outlet section 203 in the air supply direction gradually increases, the flow rate of the airflow when passing through the air outlet section 203 can be gradually reduced, so that the airflow blown out through the air outlet 104 is soft, thereby forming comfortable wind and improving the air outlet effect of the air conditioner 100. "Comfortable wind" refers to: the airflow with a suitable temperature and a slow wind speed after the heat exchange air and the indoor air are mixed.

[0063] It should be noted that the air outlet area at the air outlet section 203 is defined by the air outlet assembly 2, that is, the first air duct wall 21, the second air duct wall 22 and the guide member 3. The air outlet section 203 defined by the first air duct wall 21 and the second air duct wall 22 can be configured to be arranged with equal spacing of opening sizes along the air supply direction, and can also be configured to be gradually expanded along the air supply direction.

[0064] like Figure 2As shown, in some embodiments of the present application, the first air duct wall 21 includes: a first guide section 211, a second guide section 212 and a third guide section 213, the distance between the first guide section 211 and the second air duct wall 22 gradually decreases toward the guide section 202 side, the second guide section 212 is connected to the first guide section 211 and is provided with a first guide port 2121, the third guide section 213 is connected to the second guide section 212, and the distance between the third guide section 213 and the second air duct wall 22 gradually increases toward the air outlet 104 side of the shell 1.

[0065] like Figure 2 As shown, in some embodiments of the present application, the second air duct wall 22 includes: a fourth guide section 221, a sixth guide section 223 and a sixth guide section 223, the distance between the fourth guide section 221 and the first air duct wall 21 gradually decreases toward the guide section 202 side, the sixth guide section 223 is connected to the fourth guide section 221, and is provided with a second guide port 2221, the sixth guide section 223 is connected to the sixth guide section 223, and the distance between the sixth guide section 223 and the first air duct wall 21 gradually increases toward the air outlet 104 side of the shell 1.

[0066] Among them, the first guide section 211 and the fourth guide section 221 are arranged oppositely, the second guide section 212 and the sixth guide section 223 are arranged oppositely, and the third guide section 213 and the sixth guide section 223 are arranged oppositely. Thus, an air inlet section 201 is formed between the first guide section 211 and the fourth guide section 221, and the opening size of the air inlet section 201 gradually decreases in the air supply direction; a guide section 202 is formed between the second guide section 212 and the fifth guide section 222, and the second guide section 212 and the sixth guide section 223 are respectively provided with a first guide port 2121 and a second guide port 2221; an air outlet section 203 is formed between the third guide section 213 and the sixth guide section 223, and the opening size of the air outlet section 203 gradually increases in the air supply direction.

[0067] like Figure 4 As shown, in some embodiments of the present application, the opening size of the connection between the air inlet section 201 and one side of the fan assembly 4 is L1, and the opening size of the connection between the air inlet section 201 and the drainage section 202 is L, and the relationship is satisfied: 0.2L1≤L≤0.75L1.

[0068] Among them, in the air supply direction, the opening size of the air inlet section 201 gradually decreases toward the side of the drainage section 202, so that after the gas flows through the air inlet section 201, the gas flow rate flowing into the drainage section 202 increases, so as to generate suction at the drainage section 202, and introduce the indoor air outside the air outlet component 2 into the air outlet duct.

[0069] like Figure 4As shown, in some embodiments of the present application, the opening size of the air outlet section 203 connected to the air outlet 104 is L2, and the relationship is satisfied: 0.2L2≤L≤0.75L2. In the air supply direction, the heat exchange air mixed with the indoor air is discharged to the side of the air outlet section 203, and the flow rate of the gas is reduced.

[0070] like Figure 3 As shown, in some embodiments of the present application, the first air duct wall 21 is provided with a first air guide port 2121, the distance between the air guide member 3 and the first air guide port 2121 is L3, and the relationship is satisfied: 0.2L1≤L3≤0.75L1, 0.2L2≤L3≤0.75L2.

[0071] like Figure 3 As shown, in some embodiments of the present application, the second air duct wall 22 is provided with a second air guide port 2221, the distance between the air guide member 3 and the second air guide port 2221 is L4, and the relationship is satisfied: 0.2L1≤L4≤0.75L1, 0.2L2≤L4≤0.75L2.

[0072] Reference Figure 3 The guide member 3 further includes a transition section 33, which is connected between the first guide section 211 and the second guide section 212, and is arranged in the guide section 202. The distance between the guide member 3 and the guide port refers to the vertical distance between the guide member 3 and the guide port on the side opposite to the guide port.

[0073] It can be understood that when L3 and L4 satisfy the above-mentioned relationship, the air flow permeability on both sides of the guide member 3 (i.e., between the guide member 3 and the first air duct wall 21, and between the guide member 3 and the second air duct wall 22) can be guaranteed, and suction can be generated at the first air guide port 2121 and the second air guide port 2221 respectively, so that the indoor air at the first air guide port 2121 and the second air guide port 2221 can be sucked into the air outlet channel 20.

[0074] like Figure 5 As shown, in some embodiments of the present application, the first air duct wall 21 is provided with a first air inlet 2121, and the angle between the air inlet 2121 and the air supply direction of the air outlet channel 20 is α, and the relationship is satisfied: 0°<α≤90°.

[0075] like Figure 4 As shown, in some embodiments of the present application, the second air duct wall 22 is provided with a second air guide port 2221, and the angle between the air guide direction of the second air guide port 2221 and the air supply direction of the air outlet channel 20 is β, and the relationship is satisfied: 0°<β≤90°.

[0076] It is understandable that the drainage direction of the drainage port needs to have a certain angle with the air supply direction (that is, the angle is greater than 0°) so that the indoor air can flow into the air outlet channel 20, and as the angle increases, the mixing effect of the indoor air and the heat exchange air is better.

[0077] If the air flow direction of the air inlet to the indoor air forms an obtuse angle with the air supply direction, the air flow from the air inlet into the air outlet channel 20 will produce resistance to the flow of the heat exchange air, thereby affecting the air outlet effect of the air conditioner 100. Therefore, when the angles α and β meet the above parameters, the air outlet effect of the air conditioner 100 can be guaranteed while ensuring the mixing effect of the heat exchange air and the indoor air.

[0078] like Figure 1 As shown, in some embodiments of the present application, the opening size of the drainage port is K, and satisfies the relationship: 2mm≤K≤35mm. It should be noted that the length of the portion of the air outlet assembly 2 used to define the formation of the drainage section 202 (such as the second drainage section 212 and the fifth drainage section 222 mentioned above) must be greater than or equal to the opening size K of the drainage port. Among them, the opening size of the drainage port can be designed according to the drainage volume requirement of the air conditioner 100. The larger the opening size of the drainage port, the greater the amount of indoor air introduced into the air outlet channel 20 at the drainage port.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the air conditioner 100 also includes an air guide plate 5, which is rotatably disposed in the air outlet channel 20, and the air guide plate 5 is used to guide the airflow in the air outlet channel 20 to achieve multiple air supply modes of the air conditioner 100.

[0082] In the description of the present application, “plurality” means two or more.

[0083] In the description of the present application, a first feature being “on” or “under” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact with each other but are in contact with each other via another feature therebetween.

[0084] In the description of the present application, “above”, “over” and “above” a first feature to a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.
