Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more particularly to an air conditioner. Background Technology

[0002] Existing air conditioning products include indoor units and outdoor units. Indoor units are typically used for functions such as cooling, heating, and ventilation in indoor environments.

[0003] In related technologies, indoor units typically include a fresh air function. This means the indoor unit can improve indoor air quality by expelling stale indoor air and drawing in fresh outdoor air. To enhance the user experience, the fresh air outlet is usually located near the cool air outlet, mixing the fresh and cool air to improve the unit's airflow. However, because the fresh air is drawn in from the outside and is warmer, close proximity to the cool air outlet can cause condensation, leading to wastewater accumulation or mold growth at either outlet, making cleaning difficult for users. Utility Model Content

[0004] This application discloses an air conditioner to solve the problem of condensation or dirt that is difficult to clean from the air guide structure.

[0005] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0006] Indoor unit;

[0007] The indoor unit includes:

[0008] Housing, the housing comprising:

[0009] A shell body having an inner cavity;

[0010] A front panel is connected to the shell body and has an indoor air outlet that communicates with the inner cavity.

[0011] The fresh air structure is disposed in the inner cavity;

[0012] A cooling air structure is provided in the inner cavity;

[0013] An air guiding structure is provided at the indoor air outlet. The air guiding structure forms a fresh air guiding channel and a cold air guiding channel. The fresh air guiding channel is connected to the fresh air structure, and the cold air guiding channel is connected to the cold air structure.

[0014] The air guiding structure includes:

[0015] The first air guide is constructed in an annular shape, and the inner annular side of the first air guide forms the cold air guiding channel.

[0016] The second air guide is constructed in a ring shape and is arranged around the outer periphery of the first air guide. The second air guide is spaced apart from the first air guide so that the outer ring side of the first air guide and the inner ring side of the second air guide form the fresh air guiding channel.

[0017] The second air guide component can be detachably connected to both the front panel and the first air guide component.

[0018] The air conditioner disclosed in this application includes a first air guide and a second air guide in its air guiding structure. The second air guide is arranged around the outer periphery of the first air guide. The inner ring side of the first air guide is constructed as a cold air guiding channel. The inner ring side of the second air guide and the outer ring side of the first air guide together construct a fresh air guiding channel. Thus, through this circumferentially enclosing design of the fresh air guiding channel and the cold air guiding channel, the fresh air and cold air of the air conditioner can be mixed and blown together, achieving a mixed air effect. Building upon this mixed air effect, this application further considers the following: when fresh air and cold air are mixed, moisture in the fresh air may condense on the first or second air guide, making cleaning difficult. Furthermore, since the air guiding structure is located on the front panel, external dust and mold can easily accumulate on the air guiding structure, also making cleaning difficult for the user. Therefore, in the air guiding structure disclosed in this application, the second air guide is detachably connected to the front panel, and the first air guide is detachably connected to the second air guide. This allows for the initial removal of the entire air guide structure from the front panel, enabling the cleaning of the indoor air outlet and the outer ring of the second air guide component. Then, the first and second air guide components are disassembled separately, and the inner and outer rings of the first air guide component and the inner ring of the second air guide component are cleaned. This process ensures the cleaning of both the fresh air and cool air ducts, and facilitates easy disassembly and assembly, allowing users to regularly maintain the cleanliness of the air guide structure.

[0019] As some alternative implementations, the second air guide includes:

[0020] The first ring portion is disposed at the indoor air outlet and extends towards the inner cavity along the depth direction of the housing;

[0021] A second ring portion, connected to the end of the first ring portion away from the inner cavity, the second ring portion comprising:

[0022] The fresh air guiding channel is jointly constructed between the first inner ring side, the first ring portion, the first inner ring side, and the outer ring side of the first air guide component.

[0023] On the first outer ring side, there are two opposing first mounting portions along the width direction of the housing. The first mounting portions are spaced apart from the first outer ring side to form grooves. The two grooves are respectively engaged with two opposing edge sides of the front panel along the width direction of the housing, so that the second air guide can be detachably connected to the front panel.

[0024] In this application, when the second air guide is detachably connected to the front panel, a first mounting portion is provided on the second ring portion of the second air guide, and a groove is formed by the first mounting portion and the first outer ring side of the second ring portion. The second ring portion is located on the side of the second air guide away from the inner cavity, and users typically grasp the second ring portion first when disassembling the second air guide. Therefore, providing the first mounting portion on the second ring portion to form a groove facilitates the user's gripping of the first mounting portion and alignment of the groove with the edge of the front panel for engagement. Furthermore, the engagement position of the first mounting portion and the groove is located on the outermost side of the air guide structure, making it easy for the user to align and engage with the edge of the front panel, thus facilitating installation.

[0025] As some alternative implementations, the first mounting part is provided with a first hook facing the first outer ring side, and the edge side of the front panel is provided with a second hook, and the first hook is engaged with the second hook.

[0026] While considering the ease of disassembly of the second air guide component, this application also considers the installation stability of the second air guide component on the front panel. To this end, this application provides a first hook on the surface of the first mounting portion facing the first outer ring, and a corresponding second hook on the edge side of the front panel. The first hook engages with the second hook, thereby ensuring the second air guide component is stably secured to the front panel, improving its installation stability. Furthermore, providing hooks on the edge side of the front panel allows the second air guide component to largely cover the front panel, increasing the connection area between the second air guide component and the front panel, further enhancing the stability of the connection.

[0027] In some alternative embodiments, the indoor air outlet is configured to be circular, and both the first air guide and the second air guide are annular;

[0028] The edge side of the front panel is also provided with:

[0029] A slot portion, along the width direction of the housing, is provided corresponding to the second hook. The first hook passes through the slot portion to engage with the second hook. The two opposite sides of the slot portion in the circumferential direction around the indoor air outlet abut against the first hook. The slot portion is configured to restrict the second air guide member from rotating around the circumferential direction of the indoor air outlet, and / or...

[0030] The first hook has a first contact surface, the second hook has a second contact surface, the first contact surface abuts against the second contact surface, and at least one of the first contact surface and the second contact surface is an inclined surface.

[0031] The indoor air outlet is constructed in a circular shape, and the first and second air guides are constructed in corresponding annular shapes. This allows vortices to be formed at the outlets of the first and second air guides, respectively. This effectively utilizes aerodynamic design and facilitates the effective mixing of fresh and cold air after they exit from the fresh air guide channel and the cold air guide channel, thereby realizing the air mixing function of the air conditioner.

[0032] Because the groove formed by the first mounting part and the first outer ring side of the second air guide is engaged with the edge side of the front panel, and when the second air guide and the indoor air outlet are respectively constructed as annular and circular, the corresponding edge sides of the groove and the front panel are constructed as arcs. This makes it easy for the groove to rotate relative to the edge side of the front panel around the circumference of the indoor air outlet, hindering the stable installation of the second air guide. To address this, a slot is also provided on the edge side of the front panel. When the first hook and the second hook engage along the width direction of the housing, the first hook can pass through the slot before engaging with the second hook. Therefore, when the first hook is located in the slot and the second air guide may rotate relative to the front panel, the first hook is blocked by the two groove walls in the circumferential direction around the indoor air outlet, thus preventing the second air guide from rotating relative to the edge side of the front panel and achieving stable installation of the second air guide on the edge side of the front panel.

[0033] Considering the detachable nature of the second air guide component from the front panel, when the first and second hooks engage, one of their contact surfaces is constructed as an inclined surface. Thus, when the first hook needs to disengage relative to the second hook, the inclined surface of the first and second contact surfaces slides relative to the other contact surface, facilitating disengagement and enabling the second air guide component to be easily detached from the front panel.

[0034] As some alternative implementations, the first ring portion includes:

[0035] The second outer ring side is connected to the first outer ring side;

[0036] The second inner ring side is connected to the first inner ring side. The second inner ring side is provided with a second mounting part. The second mounting part is configured to be detachably connected to the first air guide, so that the second inner ring side is spaced apart from the outer ring side of the first air guide.

[0037] The fresh air guiding channel is formed by the outer ring side of the first air guide, the second mounting part, and the second inner ring side together with the first inner ring side.

[0038] This application achieves both the detachability of the second air guide relative to the front panel and the detachability of the second air guide relative to the first air guide. Specifically, this application provides a second mounting part on the second inner ring side of the first ring portion of the second air guide, and the first air guide is detachably connected to the second mounting part, making the first air guide detachable relative to the second air guide. From the installation position of the first air guide on the second air guide, the first air guide is installed on the first ring portion, which is closer to the inner cavity than the second ring portion. The second mounting part is located on the second ring portion, offset from the second mounting part on the first ring portion. This fully utilizes the space of the second air guide, ensuring that the installation positions of the first and second mounting parts are staggered, thus avoiding structural interference when the first and second mounting parts are installed relative to each other, which would affect the ease of assembly and disassembly.

[0039] Furthermore, when the first air guide is installed on the second air guide through the second mounting part, the second mounting part restricts the first air guide, so that the outer ring side of the first air guide and the second inner ring side are spaced apart to form a fresh air guiding channel, preventing the first air guide and the second air guide from being installed too close together and affecting the guiding of fresh air.

[0040] As some alternative implementations, the second mounting part includes:

[0041] The mounting plate portion is disposed around the second inner ring side and extends in the direction toward the center of the second inner ring side. The first inner ring side, the second inner ring side, the mounting plate portion and the outer ring side of the first air guide are connected in sequence to form the fresh air guide channel.

[0042] The third hook is disposed on the mounting plate and is spaced apart from the second inner ring side along the width direction of the housing;

[0043] The outer ring side of the first air guide is provided with a recess, and the third hook is engaged with the recess so that the second inner ring side is spaced apart from the outer ring side of the first air guide.

[0044] The second mounting section is constructed by a mounting plate and a third hook. The mounting plate is positioned near the inner cavity, preventing fresh air from returning to the inner cavity when fresh air blows outward from one side. The third hook, attached to the mounting plate, is positioned relative to the second inner ring, allowing the recess on the first air guide to engage with the third hook, thus creating a fresh air channel and facilitating fresh air delivery.

[0045] In addition, the first air guide and the second mounting part are engaged by a hook and a recess to facilitate relative disassembly and installation between the first air guide and the second mounting part.

[0046] As some alternative implementations, the housing further includes:

[0047] An air guide plate is connected to the front panel on the side adjacent to the inner cavity. The air guide plate and the front panel are spaced apart to form a fresh air transmission channel, and the fresh air transmission channel is connected to the fresh air structure.

[0048] The first ring portion is provided with a connecting port, which is configured to connect the fresh air transmission channel and the fresh air guide channel.

[0049] To avoid the fresh air transmission channel affecting the cooling air structure within the cavity and to improve the spatial layout of the indoor unit, an air guide plate is installed on the front panel near the cavity. This guide plate directs fresh air along the front panel, minimizing its impact on the cavity's space. Furthermore, the air guide structure is positioned at the indoor air outlet on the front panel. When fresh air travels through the fresh air transmission channel near the front panel to the air guide channel, the path is shorter, allowing the fresh air structure to deliver outdoor fresh air more quickly to the air guide structure, ensuring synchronized fresh and cooling air output.

[0050] As some alternative implementations, a first positioning portion is formed on the lower side of the second air guide along the height direction of the indoor unit, and a second positioning portion is formed on the front panel corresponding to the first positioning portion. The second positioning portion is configured to support the first positioning portion so that the second air guide is positioned and installed with the front panel.

[0051] In the installation of the air guide structure, either the first air guide component can be assembled with the second air guide component first, and then the second air guide component can be installed on the front panel, or the second air guide component can be installed on the front panel first, and then the first air guide component can be installed on top of the second air guide component. In other words, to achieve effective installation of the air guide structure on the front panel, the installation of the second air guide component with the front panel is crucial. Therefore, to ensure effective installation of the second air guide component with the front panel, it needs to be positioned and installed correctly, and then the second air guide component should be aligned with the edge of the front panel and snapped in place. This prevents incorrect installation of the second air guide component, allowing users to align it with the first and second positioning parts after cleaning the air guide structure, avoiding repeated disassembly and reassembly due to incorrect installation.

[0052] As some alternative implementations, the first air guide has a cavity that is isolated from the fresh air guide channel and the cold air guide channel, and the cavity is configured to reduce heat transfer between the fresh air guide channel and the cold air guide channel.

[0053] When the airflow guiding structure is designed, if the fresh air guiding channel and the cold air guiding channel are placed close together, the cold air in the cold air guiding channel may cool the fresh air in the fresh air guiding channel, causing condensation of water vapor in the fresh air. To address this, a cavity is formed in the first air guiding component. By utilizing the poor thermal conductivity of air, heat transfer between the fresh air guiding channel and the cold air guiding channel is reduced, thus preventing condensation of water vapor in the fresh air.

[0054] As some optional implementations, the air guiding structure further includes:

[0055] A heat insulation component is provided, which is arranged around the outer ring side of the first air guide component, and the heat insulation component is spaced apart from the outer ring side of the first air guide component so that the cavity is formed between the heat insulation component and the outer ring side of the first air guide component.

[0056] To further enhance the thermal insulation effect of the cavity, this application provides a thermal insulation element on the outer ring side of the first air guide to form the cavity. On the one hand, the cavity itself can reduce heat transfer, and the thermal insulation element can further reduce heat transfer, which helps to prevent the fresh air from being affected by cold air, causing water vapor in the fresh air to condense in the fresh air guide channel.

[0057] Compared with the prior art, this application has at least the following beneficial effects:

[0058] The air conditioner disclosed in this application includes a first air guide and a second air guide in its air guiding structure. The second air guide is arranged around the outer periphery of the first air guide. The inner ring side of the first air guide is constructed as a cold air guiding channel. The inner ring side of the second air guide and the outer ring side of the first air guide together construct a fresh air guiding channel. Thus, through this circumferentially enclosing design of the fresh air guiding channel and the cold air guiding channel, the fresh air and cold air of the air conditioner can be mixed and blown together, achieving a mixed air effect. Building upon this mixed air effect, this application further considers the following: when fresh air and cold air are mixed, moisture in the fresh air may condense on the first or second air guide, making cleaning difficult. Furthermore, since the air guiding structure is located on the front panel, external dust and mold can easily accumulate on the air guiding structure, also making cleaning difficult for the user. Therefore, in the air guiding structure disclosed in this application, the second air guide is detachably connected to the front panel, and the first air guide is detachably connected to the second air guide. This allows for the initial removal of the entire air guide structure from the front panel, enabling the cleaning of the indoor air outlet and the outer ring of the second air guide component. Then, the first and second air guide components are disassembled separately, and the inner and outer rings of the first air guide component and the inner ring of the second air guide component are cleaned. This process ensures the cleaning of both the fresh air and cool air ducts, and facilitates easy disassembly and assembly, allowing users to regularly maintain the cleanliness of the air guide structure.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] In this application, the terms "front," "rear," "inner," "outer," and "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0075] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0076] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0077] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0078] In related technologies, indoor units are typically equipped with a fresh air function. That is, the indoor unit can improve indoor air quality by expelling stale indoor air and drawing in fresh outdoor air. To enhance the user experience, the fresh air outlet is usually positioned near the cool air outlet, allowing the fresh and cool air to mix and improve the unit's airflow efficiency. However, since fresh air is drawn in from outdoors, it is warmer and contains more moisture. When the fresh air duct and the cold air duct are placed close together, especially when the fresh air duct surrounds the cold air duct, the two airflows can easily mix as they exit from the outer edges of either duct. The cold air, being colder at the moment of exiting the cavity, is more prone to condensation due to the moisture in the fresh air adhering to and condensing at the outer edges of either duct. This condensation can easily cause the air duct structure to become dirty. Furthermore, the compact design makes it difficult to effectively clean the dirt and condensation within the fresh and cold air ducts.

[0079] Based on this, this application discloses an air conditioner in which the first air guide component and the second air guide component of the air guide structure are detachable, and the second air guide component is also detachable relative to the housing, so that the air guide structure can be disassembled for cleaning. In this way, the fresh air guide channel and the cold air guide channel can be cleaned, and the disassembly and assembly are convenient, making it easy for users to maintain the hygiene of the air guide structure.

[0080] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0081] Please see Figure 1 This application discloses an air conditioner, which may include an indoor unit 100 and an outdoor unit (not shown). The indoor unit 100 is usually installed indoors and exchanges heat with indoor air through an indoor evaporator. The outdoor unit is installed outdoors and connected to the indoor unit 100. It mainly compresses the refrigerant and delivers it to the indoor unit to achieve a cooling or heating effect.

[0082] Please see Figure 2 In some embodiments, the indoor unit 100 includes a housing 1, the housing 1 having an inner cavity 1a, and the housing 1 having an indoor air inlet 1b and an indoor air outlet 1c, the indoor air outlet 1c and the indoor air inlet 1b being connected to the inner cavity 1a.

[0083] In some embodiments, the indoor unit may be a wall-mounted indoor unit or a floor-standing indoor unit.

[0084] For example, taking a vertical indoor unit as an example, the casing 1 has a depth direction, a width direction, and a height direction, such as... Figure 1 In the example, X indicates the width of the housing, Y indicates the depth of the housing, and Z indicates the height of the housing.

[0085] In some embodiments, the housing 1 includes a housing body 11, the housing body 11 having an inner cavity 1a.

[0086] In some embodiments, the housing 1 includes a front panel 12 connected to the housing body 11, and the front panel 12 forms an indoor air outlet 1c that communicates with the inner cavity 1a.

[0087] In some embodiments, the indoor unit 100 includes a cooling air structure (not shown).

[0088] In some embodiments, the cooling air structure is located in the inner cavity 1a.

[0089] In some embodiments, the cooling air structure includes a heat exchange volute (not shown).

[0090] In some embodiments, the cooling structure includes an indoor heat exchanger (not shown).

[0091] In some embodiments, an indoor heat exchanger is disposed inside a heat exchange volute and is used to exchange heat with indoor air entering the heat exchange volute.

[0092] In some embodiments, the cooling structure includes a heat exchange fan (not shown).

[0093] In some embodiments, the heat exchange fan is disposed in the heat exchange volute and is located in front of the indoor heat exchanger. The heat exchange fan is used to provide power for the flow of indoor air.

[0094] Driven by the heat exchange fan, indoor air enters the heat exchange volute through the air inlet 1b of the heat exchange chamber and exchanges heat with the indoor heat exchanger. After heat exchange, the indoor air is discharged from the heat exchange volute through the heat exchange outlet and then discharged from the indoor air outlet 1c.

[0095] In other words, the heat exchange volute is used to house the indoor heat exchanger and the heat exchange fan, and to provide an air cavity for the indoor heat exchanger and the heat exchange fan.

[0096] In some embodiments, the cooling structure includes a fan (not shown), which is disposed in the inner cavity 1a along the height direction of the housing 1, that is, the rotation axis of the fan is perpendicular to the horizontal plane. The fan can be driven by a motor. When the vertical air conditioner is working, the motor drives the fan to rotate. The outside air first blows through the indoor heat exchanger and exchanges heat with the indoor heat exchanger before entering the fan and being blown out from the indoor air outlet under the action of the fan.

[0097] Please see Figure 2 In some embodiments, the indoor unit 100 includes a fresh air structure 2, which is disposed in the inner cavity 1a.

[0098] In some embodiments, the fresh air structure 2 includes a fresh air unit (not shown) configured to draw fresh outdoor air into the indoor unit 100.

[0099] In some embodiments, the fresh air structure 2 includes a filter (not shown) for filtering impurities in the fresh air drawn into the indoor unit 100 by the fresh air unit to ensure that the fresh air is clean and hygienic.

[0100] In some embodiments, the fresh air structure 2 includes an exhaust fan (not shown) for exhausting stale indoor air to the outside.

[0101] In some embodiments, the outdoor unit of an air conditioner includes an outer casing, an outdoor heat exchanger, and an outdoor fan.

[0102] In some embodiments, an outdoor accommodating space is provided inside the outer shell, wherein the outdoor fan and the outdoor heat exchanger are located in the outdoor accommodating space.

[0103] In some embodiments, the outer shell of the chamber is provided with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor containment space. The outdoor air inlet is used to introduce outdoor air into the outdoor containment space, and the outdoor air outlet is used to exhaust air from the outdoor containment space to the outside of the outdoor containment space.

[0104] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor containment space through the outdoor air inlet and exchange heat with the outdoor heat exchanger. The outdoor air after heat exchange flows out of the outdoor containment space through the outdoor air outlet.

[0105] In some embodiments, the outdoor unit of the air conditioner further includes a compressor and a throttling device, both of which are located within the outdoor containment space.

[0106] In some embodiments, an air conditioner performs a refrigeration cycle by using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplying refrigerant to conditioned and heat-exchanged air.

[0107] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature, low-pressure state and discharges it into a high-temperature, high-pressure state. The discharged refrigerant gas flows into the condenser.

[0108] In some embodiments, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0109] In some embodiments, the throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0110] In some embodiments, the evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0111] In some embodiments, the evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the cycle, the temperature of the indoor space can be regulated.

[0112] In some embodiments, of the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0113] Please see also Figures 3 to 5In some embodiments, the indoor unit 100 includes an air guide structure 3, which is located at the indoor air outlet 1c. The air guide structure 3 forms a cold air guide channel 3a and a fresh air guide channel 3b. The fresh air guide channel 3b is connected to the fresh air structure 2, and the cold air guide channel 3a is connected to the cold air structure.

[0114] In the air guiding structure 3 disclosed in this application, the cold air structure and the fresh air structure 2 are connected through one air guiding structure 3, thereby realizing the mixed air output of cold air and fresh air, which is beneficial to improving the freshness of the air output from the indoor unit 100.

[0115] Please see Figure 2 In some embodiments, the housing 1 further includes an air guide plate 13, which is connected to the side of the front panel 12 adjacent to the inner cavity 1a. The air guide plate 13 and the front panel 12 are spaced apart to form a fresh air transmission channel 13a (see...). Figure 8 The fresh air transmission channel 13a is connected to the fresh air structure 2.

[0116] To avoid the fresh air transmission channel 13a affecting the cooling air structure in the inner cavity 1a, and to improve the spatial layout of the indoor unit 100, a guide vane 13 is installed on the side of the front panel 12 adjacent to the inner cavity 1a. The guide vane 13 directs the fresh air along the front panel 12, reducing the space occupied in the inner cavity 1a. Furthermore, the air guide structure 3 is located at the indoor air outlet 1c of the front panel 12. When the fresh air passes through the fresh air transmission channel 13a adjacent to the front panel 12 and reaches the fresh air guide channel 3b (see...),... Figure 8 When the path is shorter, the fresh air structure 2 can deliver the outdoor fresh air to the air guide structure 3 more quickly, so that the fresh air and the cold air can be delivered synchronously.

[0117] Please see Figures 5 to 7 In some embodiments, the air guiding structure 3 includes a first air guiding element 31, and a cold air guiding channel 3a is formed on the inner ring side of the first air guiding element 31.

[0118] For example, when the first air guide 31 is configured as an annular shape, a channel for guiding cold air can be formed on the inner ring side of the first air guide 31. The cold air blown out from the inner cavity 1a can be blown out along the inner ring side of the first air guide 31 to achieve effective air guiding of cold air.

[0119] In some embodiments, the air guiding structure 3 includes a second air guiding member 32, which is configured as an annular ring. The second air guiding member 32 is arranged around the outer periphery of the first air guiding member 31, and the second air guiding member 32 and the first air guiding member 31 are spaced apart.

[0120] For example, when the annular second air guide 32 is arranged around the outer periphery of the first air guide 31 and the second air guide 32 is spaced apart from the first air guide 31, the fresh air guide channel 3b is formed by utilizing the outer ring side of the first air guide 31 and the inner ring side of the second air guide 32, so that the fresh air guide channel 3b and the cold air guide channel 3a are arranged adjacent to each other, which is beneficial for the fresh air and cold air to mix after being discharged.

[0121] In some embodiments, the second air guide 32 can be detachably connected to both the front panel 12 and the first air guide 31.

[0122] For example, the second air guide 32 is detachably connected to the front panel 12, and the first air guide 31 is detachably connected to the second air guide 32.

[0123] In the indoor unit 100 of the air conditioner disclosed in this application, the air guide structure 3 is arranged around the outer periphery of the first air guide 31 via a second air guide 32. The inner ring side of the first air guide 31 is constructed as a cold air guide channel 3a, and the inner ring side of the second air guide 32 and the outer ring side of the first air guide 31 together construct a fresh air guide channel 3b. The air guide structure 3, by setting the fresh air guide channel 3b and the cold air guide channel 3a, allows fresh air and cold air to mix and be blown. However, when fresh air and cold air mix, moisture in the fresh air may condense on the first air guide 31 or the second air guide 32, making cleaning difficult. Furthermore, since the air guide structure 3 is located on the front panel 12, external dust and mold can easily accumulate on it, also making cleaning difficult for the user. Therefore, in the air guide structure 3 disclosed in this application, if... Figure 6 and Figure 7 As shown, the second air guide 32 is detachable from the front panel 12, and the first air guide 31 is detachable from the second air guide 32. This allows the entire air guide structure 3 to be removed from the front panel 12 first, and the indoor air outlet 1c and the outer ring side of the second air guide 32 to be cleaned. Then, the first air guide 31 and the second air guide 32 can be disassembled separately, and the inner and outer ring sides of the first air guide 31 and the inner ring side of the second air guide 32 can be cleaned. This ensures that the fresh air duct 3b and the cold air duct 3a are cleaned, and the disassembly and assembly are convenient, allowing users to regularly maintain the hygiene of the air guide structure 3.

[0124] It is understood that the detachable connection of the second air guide 32 relative to the front panel 12 includes, but is not limited to, the connection between hooks and hooks, the connection between hooks and grooves, etc., and the detachable connection of the first air guide 31 relative to the second air guide 32 includes, but is not limited to, the connection between hooks and hooks, the connection between hooks and grooves, etc.

[0125] The following text will take the hook connection between the second air guide 32 and the front panel and the hook groove connection between the first air guide 31 and the second air guide 32 as examples to introduce in detail the detachable connection structure between the second air guide 32 and the front panel 12, as well as the detachable connection structure between the first air guide 31 and the second air guide 32.

[0126] In some embodiments, the shape of the indoor air outlet 1c is configured as circular, and both the first air guide 31 and the second air guide 32 are configured as annular.

[0127] When the indoor air outlet 1c is constructed to be circular, the first air guide 31 and the second air guide 32 can be constructed to be annular in order to be installed in the indoor air outlet 1c. The annular construction of the first air guide 31 and the second air guide 32 allows for the formation of vortices between the fresh air and the cold air at their respective outlets, effectively utilizing aerodynamic design and facilitating effective mixing of fresh air and cold air after they exit through the fresh air guide channel 3b and the cold air guide channel 3a.

[0128] Please see also Figures 5 to 8 In some embodiments, the second air guide 32 includes a first ring portion 321, which is disposed at the indoor air outlet 1c and extends toward the inner cavity 1a along the depth direction of the housing 1.

[0129] As can be seen from the foregoing, the fresh air transmission channel 13a and the fresh air guide channel 3b are interconnected. Specifically, a connecting port 321c is provided on the first ring 321, and the connecting port 321c is configured to connect the fresh air transmission channel 13a and the fresh air guide channel 3b.

[0130] In some embodiments, the second air guide includes a second ring portion 322, which is connected to the end of the first ring portion 321 away from the inner cavity 1a. The second ring portion 322 includes a first inner ring side 322a and a first outer ring side 322b, which together form a fresh air guiding channel 3b. The first outer ring side 322b has two opposing first mounting portions 323 along the width direction of the housing 1. The first mounting portions 323 and the first outer ring side 322b are spaced apart to form a groove 3c. The two grooves 3c are respectively engaged with two opposing edge sides of the front panel 12 along the width direction of the housing 1, so that the second air guide 32 is detachably connected to the front panel 12.

[0131] In this application, when the second air guide 32 is detachably connected to the front panel 12, a first mounting portion 323 is provided on the second ring portion 322 of the second air guide 32, and a groove 3c is formed by the first mounting portion 323 and the first outer ring side 322b of the second ring portion 322. The second ring portion 322 is located on the side of the second air guide 32 away from the inner cavity 1a. When disassembling the second air guide 32, the user typically grasps the second ring portion 322 first. Therefore, the first mounting portion 323 is provided on the second ring portion 322 to form the groove 3c, making it easier for the user to hold the first mounting portion 323 and align the groove 3c with the edge of the front panel 12 for snap-fit. Furthermore, the snap-fit ​​position of the first mounting portion 323 and the groove 3c is also located on the outermost side of the air guide structure 3, making it easier for the user to align with the edge of the front panel 12 for snap-fit, thus facilitating user installation.

[0132] Optionally, the first mounting portion 323 may be a plate extending along the extension direction of the first outer ring side 322b. In this way, the first mounting portion 323 extends parallel to the first outer ring side 322b, so that the groove 3c formed by the first mounting portion 323 and the first outer ring side 322b can extend along the extension direction of the first outer ring side 322b. The groove 3c forms a space sufficient to engage with the edge side of the front panel 12, so as to stably engage with the edge side of the front panel 12.

[0133] It is understood that the first ring portion 321 and the second ring portion 322 of the second air guide 32 can be integrally formed ring plates, for example, formed by processes such as 3D printing and injection molding. This application does not make specific limitations here.

[0134] In some embodiments, a first positioning portion 324 is formed on the lower side of the second air guide 32 along the height direction of the indoor unit 100, and a second positioning portion 121 is formed on the front panel 12 corresponding to the first positioning portion 324. The second positioning portion 121 is configured to support the first positioning portion 324 so that the second air guide 32 is positioned and installed with the front panel 12.

[0135] In the installation method of the air guide structure 3, either the first air guide component 31 can be assembled with the second air guide component 32 first, and then the second air guide component 32 can be installed on the front panel 12, or the second air guide component 32 can be installed on the front panel 12 first, and then the first air guide component 31 can be installed on the second air guide component 32. In other words, to achieve effective installation of the air guide structure 3 on the front panel 12, the installation of the second air guide component 32 with the front panel 12 needs to be carefully controlled. Therefore, to ensure effective installation of the second air guide component 32 with the front panel 12, it is necessary to first position the second air guide component 32 with the front panel 12, and then align the second air guide component 32 with the edge of the front panel 12 for snap-fit. This prevents incorrect installation of the second air guide component 32, allowing the user to align it with the first positioning part 324 and the second positioning part 121 after cleaning the air guide structure 3, avoiding repeated disassembly and reassembly due to incorrect installation of the second air guide component 32.

[0136] Optionally, the first positioning part 324 may be a plate or block extending along the width direction of the housing 1, and the second positioning part 121 may be a plate or block extending along the height direction of the housing 1.

[0137] For example, such as Figure 7 As shown in the example, when the second air guide 32 is installed in the indoor air outlet 1c, along the height direction of the housing 1, the first positioning part 324 located on the lower side of the second air guide 32 aligns with the second positioning part 121 from top to bottom. The second positioning part 121 supports the first positioning part 324 and thus supports the entire second air guide 32, thereby restricting the position of the second air guide 32 in the height direction. In this way, the connection position between the first mounting part 323 and the edge side of the front panel 12 is determined, so that the groove 3c formed by the first mounting part 323 and the first outer ring side 322b can be effectively engaged with the edge side of the front panel 12, preventing the groove 3c from not being properly engaged with the edge side of the front panel 12.

[0138] Thus, when the first positioning part 324 and the second positioning part 121 are positioned and installed along the height direction of the housing 1, the first positioning part 324, which extends along the width direction of the housing 1, has more positions to abut against the second positioning part 121, preventing the second positioning part 121 and the first positioning part 324 from being misaligned during installation.

[0139] See also Figures 5 to 8 In some embodiments, the first mounting part 323 is provided with a first hook 325 facing the first outer ring side 322b, and the edge side of the front panel 12 is provided with a second hook 122, and the first hook 325 is engaged with the second hook 122.

[0140] In this application, while considering the ease of disassembly of the second air guide 32, the stability of its installation on the front panel 12 is also taken into account. To this end, a first hook 325 is provided on the surface of the first mounting portion 323 facing the first outer ring side 322b, and a second hook 122 is correspondingly provided on the edge side of the front panel 12. The first hook 325 engages with the second hook 122, thereby enabling the second air guide 32 to be stably engaged on the front panel 12, improving the installation stability of the second air guide 32.

[0141] In addition, by providing a hook on the edge of the front panel 12, the second air guide 32 can be roughly covered on the front panel 12, which helps to increase the connection area between the second air guide 32 and the front panel 12 and improves the connection stability between the second air guide 32 and the front panel 12.

[0142] Optionally, the first hook 325 and the second hook 122 can also be configured as a combination of hook and buckle, that is, one of the first hook 325 and the second hook 122 can be configured as a buckle, and the other as a hook.

[0143] In some embodiments, the edge side of the front panel 12 is also provided with a slot 12a. Along the width direction of the housing 1, the slot 12a is provided corresponding to the second hook 122. The first hook 325 passes through the slot 12a to engage with the second hook 122. The two opposite sides of the slot 12a in the circumferential direction around the indoor air outlet 1c abut against the first hook 325. The slot 12a is configured to restrict the second air guide 32 from rotating around the indoor air outlet 1c in the circumferential direction.

[0144] For example, the slot portion 12a can be formed by forming a recessed groove 3c on the edge side of the front panel 12, and the two groove walls of the slot portion 12a are located in the circumferential direction of the indoor air outlet 1c.

[0145] Since the groove 3c formed by the first mounting part 323 and the first outer ring side 322b of the second air guide 32 is engaged with the edge side of the front panel 12, and when the second air guide 32 and the indoor air outlet 1c are respectively constructed as annular and circular, the groove 3c and the corresponding edge side of the front panel 12 are constructed as arc-shaped. As a result, the groove 3c is prone to rotate around the circumference of the indoor air outlet 1c relative to the edge side of the front panel 12, which is not convenient for the stable installation of the second air guide 32. To address this, a slot part 12a is also provided on the edge side of the front panel 12. When the first hook 325 and the second hook 122 are engaged along the width direction of the housing 1, the first hook 325 first passes through the slot part 12a before it can be engaged with the second hook 122. Furthermore, when the first hook 325 is located in the slot 12a and the second air guide 32 may rotate relative to the front panel 12, the first hook 325 is blocked by the two slot walls of the slot 12a in the circumferential direction around the indoor air outlet 1c, thereby preventing the second air guide 32 from rotating relative to the edge side of the front panel 12, and realizing the stable installation of the second air guide 32 on the edge side of the front panel 12.

[0146] See also Figures 5 to 8 In some embodiments, considering the ease of assembling and disassembling the first hook 325 and the second hook 122, the first hook 325 has a first contact surface 325a, the second hook 122 has a second contact surface 122a, the first contact surface 325a abuts against the second contact surface 122a, and at least one of the first contact surface 325a and the second contact surface 122a is an inclined surface.

[0147] For example, the first contact surface 325a of the first hook 325 can be set as an inclined surface, or the second contact surface 122a of the second hook 122 can also be set as an inclined surface, or both the first contact surface 325a of the first hook 325 and the second contact surface 122a of the second hook 122 can be set as inclined surfaces.

[0148] Considering that the second air guide 32 can be easily detached from the front panel 12, when the first hook 325 and the second hook 122 are engaged, one of the contact surfaces between them is constructed as an inclined surface. Thus, when the first hook 325 needs to disengage relative to the second hook 122, the inclined surface of the first contact surface 325a and the second contact surface 122a will slide relative to the other contact surface, facilitating the disengagement of the first hook 325 from the second hook 122, thereby enabling the second air guide 32 to be easily detached from the front panel 12.

[0149] Please see Figure 9 and Figure 10In some embodiments, the first ring portion 321 includes a second outer ring side 321a and a second inner ring side 321b, with the second outer ring side 321a connected to the first outer ring side 322b. The second inner ring side 321b is connected to the first inner ring side 322a, and the second inner ring side 321b is provided with a second mounting portion 326. The second mounting portion 326 is configured to be detachably connected to the first air guide member 31, such that the second inner ring side 321b is spaced apart from the outer ring side of the first air guide member 31. The outer ring side of the first air guide member 31, the second mounting portion 326, and the second inner ring side 321b and the first inner ring side 322a together form a fresh air guiding channel 3b.

[0150] On the one hand, this application achieves both the detachability of the second air guide 32 relative to the front panel 12 and the detachability of the second air guide 32 relative to the first air guide 31. This application provides a second mounting portion 326 on the second inner ring side 321b of the first ring portion 321 of the second air guide 32, and the first air guide 31 is detachably connected to the second mounting portion 326, making the first air guide 31 detachable relative to the second air guide 32. From the installation position of the first air guide 31 on the second air guide 32, the first air guide 31 is installed on the first ring portion 321. The first ring portion 321 is closer to the inner cavity 1a than the second ring portion 322. The second mounting portion 326 is set on the second ring portion 322, which is offset from the second mounting portion 326 on the first ring portion 321. This makes full use of the space of the second air guide 32, so that the installation positions of the first mounting portion 323 and the second mounting portion 326 are staggered, so as to avoid structural interference between the first mounting portion 323 and the second mounting portion 326 when they are installed relative to each other, which would affect the convenience of disassembly and assembly.

[0151] On the other hand, when the first air guide 31 is installed on the second air guide 32 via the second mounting part 326, the second mounting part 326 restricts the first air guide 31, so that the outer ring side of the first air guide 31 and the second inner ring side 321b are spaced apart to form a fresh air guiding channel 3b, preventing the first air guide 31 and the second air guide 32 from being installed too close together and affecting the guiding of fresh air.

[0152] Please see Figure 9 and Figure 10In some embodiments, the second mounting portion 326 includes a mounting plate portion 3261 and a third hook 3262. The mounting plate portion 3261 is arranged around the second inner ring side 321b and extends towards the center of the second inner ring side 321b. The first inner ring side 322a, the second inner ring side 321b, the mounting plate portion 3261, and the outer ring side of the first air guide 31 are sequentially connected to form a fresh air guide channel 3b. The third hook 3262 is disposed on the mounting plate portion 3261 and is spaced apart from the second inner ring side 321b along the width direction of the housing 1. The outer ring side of the first air guide 31 has a recess 311, and the third hook 3262 engages with the recess 311 so that the second inner ring side 321b is spaced apart from the outer ring side of the first air guide 31.

[0153] For example, the recess 311 on the outer ring side of the first air guide 31 engages with the third hook 3262, thereby limiting the position between the first air guide 31 and the second air guide 32. When the second mounting portion 326 is provided, it is constructed by the mounting plate portion 3261 and the third hook 3262. The mounting plate portion 3261 is located on the side adjacent to the inner cavity 1a. When fresh air blows outward from the inner cavity 1a side, the mounting plate portion 3261 can prevent the fresh air from returning to the inner cavity 1a side. Furthermore, the third hook 3262 is provided based on the mounting plate portion 3261, allowing the position of the third hook 3262 to be spaced relative to the second inner ring side 321b. This ensures that when the recess 311 on the first air guide 31 engages with the third hook 3262, the first air guide 31 is spaced from the second inner ring side 321b, facilitating the construction of the fresh air guiding channel 3b and promoting fresh air output.

[0154] In addition, the first air guide 31 and the second mounting part 326 are engaged by a hook and a recess 311 to facilitate relative disassembly and installation between the first air guide 31 and the second mounting part 326.

[0155] For example, the second mounting portion 326 extends circumferentially around the second inner ring side 321b via the mounting plate portion 3261 and toward the center of the indoor air outlet 1c, thereby forming a space on the mounting plate portion 3261 for mounting the third hook 3262 and the fresh air guide channel 3b. When the first air guide member 31 is engaged with the third hook 3262 and the outer ring side of the first air guide member 31 is spaced apart from the second inner ring side 321b, a sufficient fresh air guide channel 3b can be formed between them by the limiting effect of the third hook 3262.

[0156] It is understood that the mounting plate 3261 may be an annular plate, mounted on the second inner ring side 321b of the first ring 321 to fit the shape of the first ring 321.

[0157] In some embodiments, the first air guide 31 forms a cavity 31a, which is isolated from the fresh air guide channel 3b and the cold air guide channel 3a. The cavity 31a is configured to reduce heat transfer between the fresh air guide channel 3b and the cold air guide channel 3a.

[0158] When the air guide structure 3 is set up, if the fresh air guide channel 3b and the cold air guide channel 3a are placed close together, the cold air in the cold air guide channel 3a may cool the fresh air in the fresh air guide channel 3b, causing condensation of water vapor in the fresh air. To address this, a cavity 31a is formed in the first air guide component 31. By utilizing the poor thermal conductivity of air, the heat transfer between the fresh air guide channel 3b and the cold air guide channel 3a is reduced, thus preventing condensation of water vapor in the fresh air.

[0159] Please see Figure 9 and Figure 11 In some embodiments, the air guiding structure 3 further includes a heat insulation member 33, which is arranged around the outer ring side of the first air guiding member 31. The heat insulation member 33 is spaced apart from the outer ring side of the first air guiding member 31 so that a cavity 31a is formed between the heat insulation member 33 and the outer ring side of the first air guiding member 31.

[0160] By forming a cavity between the heat insulation component 33 and the outer ring side of the first air guide component 31, the cavity 31a itself can reduce heat transfer by utilizing the poor thermal conductivity of air. The heat insulation component 33 can further reduce heat transfer. For example, by using heat insulation materials such as glass fiber or asbestos, the heat transfer between the fresh air guide channel 3b and the cold air guide channel 3a can be reduced, which helps to prevent the fresh air from being affected by the cold air, causing water vapor in the fresh air to condense in the fresh air guide channel 3b.

[0161] Please see Figures 9 to 11 Optionally, the heat insulation component 33 may be integrally formed with the first air guide component 31 to form a cavity 31a, or the heat insulation component 33 may be detachably connected with the first air guide component 31 to form a cavity 31a.

[0162] When the heat insulation component 33 is detachably connected to the first air guide component 31, the outer ring side of the first air guide component 31 is provided with an abutment portion 312 and a support portion 313. The abutment portion 312 protrudes from the outer ring side of the first air guide component 31 along the width direction of the housing 1, and the abutment portion 312 is located on the side of the outer ring side of the first air guide component 31 away from the inner cavity 1a. The abutment portion 312 abuts against the heat insulation component 33, so that the heat insulation component 33 is spaced apart from the outer ring side of the first air guide component 31. The support portion 313 is spaced apart from the abutment portion 312 along the depth direction of the housing 1, and the support portion 313 is located on the side of the outer ring side of the first air guide component 31 near the inner cavity 1a. The support portion 313 is configured to support the heat insulation component 33, so that the heat insulation component 33 is detachably connected to the outer ring side of the first air guide component 31.

[0163] When the heat insulation component 33 is installed on the outer ring side of the first air guide 31, one surface of the heat insulation component 33 abuts against the abutting part 312, thus separating the heat insulation component 33 from the outer ring side of the first air guide 31. Simultaneously, the supporting part 313, by supporting the other surface of the heat insulation component 33, locks the position of the heat insulation component 33, preventing it from falling off the outer ring side of the first air guide 31. This application first uses the abutting part 312 to position the heat insulation component 33 on the outer ring side of the first air guide 31, forming a cavity 31a between the heat insulation component 33 and the outer ring side of the first air guide 31. Then, the supporting part 313 supports the heat insulation component 33, preventing it from falling off the outer ring side of the first air guide 31. In this way, the heat insulation component 33 can be positioned and installed on the outer ring side of the first air guide 31 while also achieving stable installation and preventing it from falling off.

[0164] Optionally, the insulation element 33 may be made of insulation materials such as fiberglass or asbestos, and this application does not make specific limitations.

[0165] Optionally, the abutting part 312 and the supporting part 313 may be protrusions or bumps protruding from the second outer ring side 321a, which are not specifically limited here.

[0166] It is understandable that, since the heat insulation component 33 is arranged in a ring on the second outer ring side 321a, there are multiple abutting parts 312 and multiple supporting parts 313 on the second outer ring side 321a. Multiple abutting parts 312 and multiple supporting parts 313 are arranged in a ring on the second outer ring side 321a to correspondingly install the heat insulation component 33.

[0167] The air conditioner disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the air conditioner and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
