Description

Technical Field

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

[0002] The direct blast of cold air from air conditioners onto the human body is a common and pressing problem that needs to be addressed. This not only causes a range of health issues such as colds, headaches, and joint pain, but also severely impacts the user experience, becoming a major pain point in air conditioner use.

[0003] To address the issue of direct cold air blowing from air conditioners, existing technologies have made numerous attempts, which can be mainly divided into two categories. First, automatic airflow control is achieved by adding an electric drive mechanism and an air guide plate. While this method effectively adjusts the airflow direction and avoids direct cold air blowing, it has significant drawbacks. The addition of the electric drive mechanism and air guide plate significantly increases the overall structural cost. Furthermore, because this structure is not removable, its exposed portion detracts from the overall aesthetics of the indoor unit during off-seasons. Second, an air guide plate structure is installed, such as hanging it on the top of the air conditioner casing or mounting it on the left or right ends of the casing via a rotating mechanism. Compared to an electric drive air guide plate, this structure is less expensive; however, it also suffers from drawbacks, namely, extreme inconvenience in disassembly, and the installation structure remaining on the air conditioner casing after disassembly, severely affecting its appearance.

[0004] Therefore, it is necessary to design an indoor air conditioning unit with an air deflector to avoid direct cold air blowing while having low structural cost, quick disassembly when not in use, and an aesthetically pleasing appearance after the air deflector is removed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the first objective of this utility model embodiment is to provide an air conditioner indoor unit. By setting a quick-release air guide plate at the bottom of the air conditioner indoor unit casing, the structure cost is low, it can not only play the role of preventing direct blowing, but also can be quickly disassembled when not in use. Moreover, the assembly structure at the bottom of the casing is not easily noticed after disassembly, the appearance of the air conditioner indoor unit is beautiful, and the user experience is improved.

[0006] The second objective of this utility model embodiment is to provide an air conditioner.

[0007] The first aspect of this utility model provides an indoor unit for an air conditioner, comprising:

[0008] The housing has an air outlet;

[0009] A fastener is provided on the housing at a position below the air outlet;

[0010] An air guide plate is configured to be movably positioned below the air outlet to block downward airflow from the air outlet, wherein the air guide plate is connected to a connector and is quickly and easily installed on the fixing member via the connector.

[0011] In the above technical solution, by setting the fixing component at the bottom of the casing and quickly connecting the air guide plate to the fixing component through the connector, the air guide plate is located below the air outlet, blocking the air outlet from blowing directly downwards. This not only achieves the function of preventing direct blowing, but also has low structural cost. Furthermore, the air guide plate can be quickly and easily removed when not in use. After the air guide plate is removed, the fixing component is located at the bottom of the casing, and its structure is not easily noticed. This makes the indoor unit of the air conditioner look beautiful and improves the user experience.

[0012] In some embodiments, the housing is provided with a base plate, the fixing member includes a guide rail, the guide rail extends forward and backward on the base plate, the air guide plate is quickly mounted on the guide rail via the connector, and can slide forward and backward relative to the guide rail.

[0013] In the above technical solution, the fixing component adopts a guide rail extending front and back along the bottom plate of the outer shell, which is effectively hidden at the bottom of the outer shell and is not easily noticed during daily use. Furthermore, the air guide plate can be fixed simply by pushing it into the guide rail during installation, and can be quickly slid off the guide rail during disassembly. The entire process requires no tools and has a short operation time, improving maintenance convenience. The air guide plate can slide back and forth on the guide rail, and the air guiding range below the air outlet can be flexibly changed by adjusting its position, enhancing its adaptability to use.

[0014] In some embodiments, the air guide plate has a storage position at the rear end of the guide rail, a disassembly position at the front end of the guide rail, and an air guiding position between the storage position and the disassembly position;

[0015] When the air guide plate is in the storage position, the projection of the air guide plate and the air outlet on the horizontal plane does not coincide or partially coincides.

[0016] When the air guide plate is in the disassembled position, the air guide plate can slide out from the front end of the guide rail;

[0017] When the air guide plate is in the air guiding position, the projection of the air outlet on the horizontal plane falls at least partially into the air guide plate.

[0018] In the above technical solution, the air guide plate can slide back and forth on the guide rail, and the position can be switched between the storage position, the air guiding position and the disassembly position by adjusting the position, so as to flexibly adjust the position of the air guide plate.

[0019] In some embodiments, the rear end of the guide rail is substantially flush with or flush with the rear wall of the housing.

[0020] In the above technical solution, when the air guide plate is in the retracted position, it abuts against the wall to prevent the air guide plate from disengaging from the rear end of the guide rail.

[0021] In some embodiments, one end of the connector is slidably connected to the guide rail, and the other end of the connector extends downward and is connected to the air guide plate, so that there is a certain distance between the air guide plate and the air outlet.

[0022] In the above technical solution, by placing the air guide plate at a certain distance from the air outlet in the vertical direction, when working in the air guide position, the air outlet is not blocked. This allows the air blown out of the air outlet to flow a certain distance and then be reflected upwards, increasing the reflection range of the air and improving the dispersion of the air.

[0023] In some embodiments, the guide rail has a limiting groove with a bottom opening, one end of the connector is slidably installed in the limiting groove, and the other end extends downward through the opening to connect with the rear end of the air guide plate.

[0024] The above technical solution can not only connect the air guide plate to the guide rail support, but also facilitate the disassembly and assembly of the connecting parts and the limiting slide groove.

[0025] In some embodiments, the connector includes a slider and a connecting arm. The slider is slidably disposed in the limiting groove. One end of the connecting arm is connected to the slider, and the other end extends through the opening and is connected to the air guide plate.

[0026] In some embodiments, the air guide plate is an arc-shaped plate, the front end of the arc-shaped plate is bent downward and extended, and the air outlet direction is set at an angle to the arc surface of the arc-shaped plate.

[0027] In the above technical solution, the downward-blowing airflow from the air outlet impacts the curved surface of the arc-shaped plate, causing the reflected airflow to deflect at a greater angle. After reflection by the arc surface, it forms a fan-shaped diffused airflow field, simultaneously increasing the effective coverage area and improving the dispersion of the airflow. The specific angle formed by the arc surface of the arc-shaped plate and the airflow direction prevents the airflow from flowing directly downwards along the arc surface, thus achieving a wide-area expansion of the airflow range and improved dispersion. This allows cold or hot air to cover the entire room more quickly, improving the cooling or heating effect of the air conditioner and enhancing user comfort.

[0028] In some embodiments, the housing is provided with a front panel, and the air outlet is located at the lower end of the front panel;

[0029] The arc-shaped plate includes a straight section and an arc-shaped section connected together. When the air guide plate slides to the air guide position, the straight section extends from back to front to below the air outlet, and the arc-shaped section extends downward in an arc shape from the straight section beyond the front plate.

[0030] In the above technical solution, given that the air outlet is generally tilted downwards, the straight section extends from back to front to below the air outlet, and the curved section extends downwards in an arc from the straight section beyond the front side of the front panel. The main airflow blown onto the curved plate is reflected, and since the front end of the curved plate extends to the front side of the front panel, the reflection range of the airflow can be expanded.

[0031] A second aspect of this utility model provides an air conditioner, including any of the air conditioner indoor units described above.

[0032] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0033] (1) In this embodiment of the air conditioner indoor unit, by setting the fixing part at the bottom of the outer shell, the air guide plate is quickly installed on the fixing part through the connector, so that the air guide plate is located below the air outlet, blocking the air outlet from blowing directly downwards. This not only achieves the function of preventing direct blowing, but also has low structural cost. Furthermore, the air guide plate can be quickly and conveniently removed from the outer shell when not in use. After the air guide plate is removed, the fixing part is located at the bottom of the outer shell, and its structure is not easily noticed. The air conditioner indoor unit has an aesthetically pleasing appearance, which improves the user experience.

[0034] (2) During operation of the air conditioner in this embodiment, the airflow blowing downwards from the air outlet impacts the arc surface of the arc-shaped plate, causing the reflected airflow to deflect at a greater angle. After reflection by the arc surface, a fan-shaped diffused airflow field is formed, which simultaneously increases the effective coverage area and improves the dispersion of the airflow. The specific angle formed by the arc surface of the arc plate and the airflow direction prevents the airflow from flowing directly downwards along the arc surface, thus achieving both a wide range of airflow expansion and improved dispersion, while also enhancing user comfort by avoiding direct airflow.

[0052] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0054] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0055] like Figures 1 to 10 As shown, this embodiment of the present invention provides an indoor air conditioning unit, which is typically installed in an indoor space and works in conjunction with the outdoor unit to jointly regulate the indoor environment. This embodiment uses a wall-mounted air conditioning unit as an example.

[0056] The indoor unit of the air conditioner includes an indoor unit body 1, which includes a casing 11 and an evaporator, a cross-flow fan, and a filter screen disposed inside the casing 11. The evaporator is located in the central area of ​​the casing 11, absorbing indoor heat during cooling and releasing heat after switching through a four-way valve during heating. The cross-flow fan is located behind or to the side of the evaporator, drawing in air from the air inlet at the top or front of the casing 11 during operation, processing it through the evaporator, and then blowing it out through the air outlet 111 of the casing 11, forming an airflow path. The filter screen covers the air inlet of the casing 11, filtering dust and impurities, protecting the evaporator, and improving air quality; it requires regular cleaning and maintenance. Optionally, the indoor unit of the air conditioner also includes a baffle plate 114, disposed at the air outlet 111 of the casing 11, which can automatically move to close or open the air outlet 111 of the casing 11.

[0057] The indoor unit of the air conditioner also includes a fixing component 2, a connecting component 4, and an air guide plate 3.

[0058] The air outlet 111 is typically located at the lower end of the front panel 113 of the outer casing 11, or at the connection between the bottom plate 112 and the front panel 113 of the outer casing 11. The fixing member 2 is located on the outer casing 11 below the air outlet 111. The air guide plate 3 is configured to be movably positioned below the air outlet 111 to prevent air from blowing downwards from the air outlet 111, thus achieving a direct-blowing function. The air guide plate 3 is connected to a connector 4 and is quickly and easily installed on the fixing member 2 via the connector 4.

[0059] The indoor unit of this utility model of an air conditioner, by setting the fixing part 2 at the bottom of the outer shell 11, and quickly connecting the air guide plate 3 to the fixing part 2 through the connector 4, so that the air guide plate 3 is located below the air outlet 111, blocking the air outlet 111 from blowing air directly downwards, can not only achieve the function of preventing direct blowing, but also has low structural cost. It can also quickly and conveniently remove the air guide plate 3 when not in use. After the air guide plate 3 is removed, the fixing part 2 is located at the bottom of the outer shell 11, and its structure is not easily noticed. The indoor unit of the air conditioner has an aesthetic appearance and improves the user experience.

[0060] In the above scheme, the fixing member 2 can be pre-embedded in the bottom wall of the outer shell 11, or it can be fitted onto the outer wall of the outer shell 11. Alternatively, a clearance cavity can be provided on the outer wall of the outer shell 11. The fixing member 2 is movable, switching positions between the clearance cavity and the outside of the outer shell 11. The connecting member 4 and the fixing member 2 do not require tools for quick release; the quick-release connection methods include, but are not limited to, magnetic fixing, hooking, and snap-fitting.

[0061] like Figures 1 to 5 As shown, the air guide plate 3 can be a straight panel or an arc-shaped panel. The straight panel or arc-shaped panel has several ventilation holes, or it can be without ventilation holes. Preferably, the air guide plate 3 does not have ventilation holes and is configured to reflect the air outlet 111.

[0062] The bottom of the outer casing 11 is provided with a base plate 112, and the fixing member 2 includes a guide rail 21 extending along the front-back direction and disposed on the base plate 112. The air guide plate 3 is slidably and quickly installed on the guide rail 21 via the connecting member 4.

[0063] The fixing component 2 of this utility model adopts a guide rail 21 extending front and back along the bottom plate 112 of the outer shell 11, which is effectively hidden at the bottom of the outer shell 11 and is not easily noticed during daily use. Furthermore, when installing the air guide plate 3, it can be fixed simply by pushing it into the guide rail 21, and it can be quickly slid off the guide rail 21 during disassembly. The entire process requires no tools and has a short operation time, improving maintenance convenience. The air guide plate 3 can slide back and forth on the guide rail 21, and the air guiding range below the air outlet 111 can be flexibly changed by adjusting its position, enhancing its adaptability to use.

[0064] The guide rail 21 is detachably or non-detachably mounted on the base plate 112. The guide rail 21 is a straight guide rail and is made of metal or hard plastic.

[0065] The air guide plate 3 has a storage position at the rear end of the guide rail 21, a disassembly position at the front end of the guide rail 21, and an air guiding position between the storage position and the disassembly position.

[0066] When the air guide plate 3 is installed, the connector 4 on the air guide plate 3 is pushed in along the front opening 212 of the guide rail 21 and fixed vertically. The connector 4 can slide back and forth along the guide rail 21.

[0067] When the air guide plate 3 is in the storage position (see...) Figure 3 and Figure 5 In some cases, the projections of the air guide plate 3 and the air outlet 111 on the horizontal plane do not coincide. Specifically, the air guide plate 3 is positioned close to the wall, directly below the base plate 112, and the front end of the air guide plate 3 is not directly below the air outlet 111. Alternatively, the projections of the air guide plate 3 and the air outlet 111 on the horizontal plane may partially coincide, meaning the front end of the air guide plate 3 is partially directly below the air outlet 111.

[0068] When the air guide plate 3 is in the disassembled position (see...) Figure 2 and Figure 4 The connector 4 can be slid out and detached from the front end of the guide rail 21. The connector 4 is a slide rail structure or a slider 41 structure. When the connector 4 is a slide rail structure, it can be supported on the upper side of the track of the guide rail 21 and slide back and forth along the track; when the connector 4 is a slider 41 structure, the slide rail structure is slidably disposed in the limiting groove of the guide rail 21. In both cases, the connector 4 can be slid out and detached from the front end of the guide rail 21.

[0069] When the air guide plate 3 is in the air guiding position, the projection of the air outlet 111 on the horizontal plane is at least partially contained within the air guide plate 3. It should be noted that the air guiding position is not a fixed point, but slides within a certain length range on the guide rail 21. At any position within this length range, the air outlet 111 can be prevented from blowing air downwards directly onto the user. Preferably, when the air guide plate 3 is in the air guiding position, the entire projection of the air outlet 111 on the horizontal plane is contained within the air guide plate 3.

[0070] The rear end of the guide rail 21 is substantially flush with or flush with the rear wall of the outer casing 11, and is used to abut against the wall to restrict the air guide plate 3 from detaching from the rear end of the guide rail 21 when the air guide plate 3 is in the storage position.

[0071] The guide rails 21 are respectively disposed on the left and right ends of the base plate 112, that is, on both ends of the length direction of the base plate 112. The connecting pieces 4 are respectively disposed on both ends of the length direction of the air guide plate 3. By providing two guide rails 21 and two connecting pieces 4, the stability of the air guide plate 3 connected to the base plate 112 can be improved.

[0072] like Figures 6 to 10As shown, the guide rail 21 has a limiting groove 211 with a bottom opening 212. One end of the connector 4 is slidably installed in the limiting groove 211, and the other end extends downward through the limiting groove 211 to connect with the rear end of the air guide plate 3. The air guide plate 3 can be positioned close to the opening 212 or vertically at a certain distance from the opening 212; the specific position can be adjusted as needed.

[0073] The opening 212 extends along the front and back, penetrating both ends of the limiting slide groove 211 in the length direction. The opening 212 is elongated, and the width of the opening 212 is smaller than the width of the bottom wall of the limiting slide groove 211. The slider 41 is placed on the bottom wall inside the limiting slide groove 211, thereby suspending the air guide plate 3 on the fixing member 2.

[0074] The connector 4 includes a slider 41 and a connecting arm 42. The slider 41 is slidably disposed in the limiting groove 211. One end of the connecting arm 42 is connected to the slider 41, and the other end passes downward through the opening 212 and is connected to the air guide plate 3. The connecting arm 42 is movably disposed in the opening 212.

[0075] The connecting arm 42 has a certain extension length in the front-back direction, and the other end of the connecting arm 42 extends forward and backward and is disposed on the top wall of the air guide plate 3 to improve the connection strength with the air guide plate 3.

[0076] Furthermore, to improve the dispersion of the airflow from the air outlet 111 by the air guide plate 3, one end of the connector 4 is slidably connected to the guide rail 21, and the other end of the connector 4 extends downward and is connected to the air guide plate 3, so that there is a certain distance between the air guide plate 3 and the air outlet 111.

[0077] This invention, by positioning the air guide plate 3 at a certain vertical distance from the air outlet 111, avoids obstructing the airflow from the air outlet 111 when operating in the air guide position. This allows the airflow from the air outlet 111 to flow a certain distance before being reflected upwards, increasing the reflection range of the wind and improving the dispersion of the wind.

[0078] Specifically, the horizontal cross-section of the slider 41 is rectangular. The connecting arm 42 is a connecting plate with a certain vertical extension length. After the other end of the connecting arm 42 passes through the opening 212, it continues to extend downwards for a certain distance and connects to the top wall of the air guide plate 3, so as to suspend the air guide plate 3 below the guide rail 21 at a certain distance from the air outlet 111.

[0079] To further improve the dispersion and speed of the airflow from the air conditioner, the air guide plate 3 of this invention is configured as an arc-shaped plate. The arc-shaped plate extends downwards in an arc shape as it extends from back to front. The arc surface of the arc-shaped plate forms an angle with the air outlet 111's airflow direction.

[0080] When the air conditioner is running, the airflow blowing downwards from the air outlet 111 impacts the curved surface of the arc-shaped plate, causing the reflected airflow to deflect at a greater angle. After reflection by the arc surface, it forms a fan-shaped diffused airflow field, simultaneously increasing the effective coverage area and improving the dispersion of the airflow. The specific angle formed by the arc surface of the arc-shaped plate and the airflow direction prevents the airflow from flowing directly downwards along the arc surface, thus achieving a wide range of airflow expansion and improved dispersion. This allows cold or hot air to cover the entire room more quickly, improving the cooling or heating effect of the air conditioner and enhancing user comfort.

[0081] The curvature of the arc plate needs to be set to be small to prevent the air outlet 111 from flowing directly downwards along the arc plate and to prevent the anti-direct-blow function from failing.

[0082] The air outlet 111 is located at the lower end of the front panel 113. The arc-shaped plate includes a straight section and an arc-shaped section connected together. When the air guide plate 3 slides to the air guide position, the straight section extends from back to front to below the air outlet 111, and the arc-shaped section extends downward in an arc from the straight section beyond the front panel 113, preventing air from blowing directly downward along the front end of the arc-shaped plate or from the front side of the arc-shaped plate when air is emitted from the air outlet 111.

[0083] Given that the air outlet 111 is generally tilted downwards to discharge air, the straight section extends from back to front to below the air outlet 111, and the curved section extends downwards in an arc from the straight section beyond the front side of the front panel 113. The main airflow blown onto the curved panel is reflected, and since the front end of the curved panel extends to the front side of the front panel 113, it can expand the reflection range of the airflow.

[0084] The second aspect of this utility model provides an air conditioner, including any of the above-described indoor units. The air conditioner includes an indoor unit and an outdoor unit, which are connected by refrigerant pipes and wiring. Through refrigerant circulation and heat exchange, they work in close coordination to achieve cooling or heating functions.

[0085] Taking air conditioning as an example: When an air conditioner is running, the indoor unit uses the evaporator to allow the refrigerant to absorb heat and evaporate, thus lowering the indoor temperature; the outdoor unit uses the compressor to compress and heat the gaseous refrigerant, and the condenser then releases this heat to the outside. The two units are seamlessly connected through refrigerant circulation and heat exchange, efficiently achieving cooling or heating.

[0086] The outdoor unit includes a casing and a compressor, condenser, axial fan, etc., housed within the casing. The compressor, as the "heart" of the refrigeration system, is typically located in the lower middle section of the casing chassis. It is responsible for compressing the low-temperature, low-pressure gaseous refrigerant returned from the indoor unit into a high-temperature, high-pressure gas to drive the refrigerant cycle. The condenser is connected to the compressor and the evaporator of the indoor unit via refrigerant piping. Forced convection cooling by the axial fan condenses the high-temperature, high-pressure refrigerant gas output from the compressor into a high-pressure liquid, which then returns to the indoor unit via refrigerant piping. After being throttled and depressurized by the expansion valve, it enters the evaporator to absorb heat again, forming a complete refrigeration cycle.

[0087] The air conditioner provided in this embodiment of the utility model includes the air conditioner indoor unit of any of the above embodiments, and therefore has the beneficial effects of the air conditioner indoor unit of any of the above embodiments, which will not be repeated here.

[0088] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0089] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
