Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as an indoor air conditioning unit and an air conditioner. Background Technology

[0002] When an air conditioner is blowing air, the hot or cold air from the heat exchanger is blown directly out of the air outlet. Especially when the cold air is blown directly out, a large temperature difference is created relative to the original indoor air temperature, which can make users feel uncomfortable. Moreover, if people are frequently exposed to this kind of cold air with a large temperature difference, they are prone to catching a cold or "air conditioning sickness".

[0003] In related technologies, a wall-mounted air conditioner is provided, including a casing with an air inlet and an air outlet. A heat exchanger and a fan are housed inside the casing. An air outlet duct, enclosed by an air outlet duct wall, is located between the air outlet and the fan. An air intake outlet communicating with the air outlet duct is opened on the air outlet duct wall. An air intake inlet is opened on the casing, forming an air intake duct between the air intake inlet and the air outlet. A second air guide plate is provided at the end edge of either the air intake or the air outlet. The second air guide plate, driven by a drive mechanism, opens or blocks the air intake or the air outlet. By adding an air intake duct, air that has not undergone heat exchange can enter the air intake duct from the air intake inlet and mix with the heat-exchanged air, resulting in a natural and gentle airflow.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, the air intake duct is set on the wall of the air outlet duct, which will cause a loss of air volume in the air conditioner during the air supply process, thus affecting the energy efficiency of the air conditioner. Summary of the Invention

This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an indoor air conditioning unit and an air conditioner. The indoor air conditioning unit is equipped with two air guide plates. The first air guide plate is used to guide air from below the indoor air conditioning unit, and the second air guide plate is used to guide air vertically. This makes the air blown out by the air conditioner softer, and there is no loss of air volume during the soft air delivery process.

[0008] In some embodiments, the indoor unit of the air conditioner includes a housing with an air outlet, and further includes a first air guide plate and a second air guide plate. The first air guide plate has a first position where the air outlet is closed and a second position where the air outlet is opened to guide airflow. The second air guide plate is disposed inside the air outlet to guide airflow vertically. When the first air guide plate is located in the first position, it is located outside the second air guide plate. When the first air guide plate is located in the second position, it is horizontally positioned below the indoor unit of the air conditioner.

[0009] Optionally, when the first air guide plate is located in the second position, the distance between the first air guide plate and the lower housing of the indoor unit of the air conditioner is greater than 30mm.

[0010] Optionally, the indoor unit of the air conditioner further includes a first driving device, which is disposed on both sides of the indoor unit of the air conditioner and is movably connected to the first air guide plate. The first driving device is used to drive the first air guide plate to move to the horizontal state.

[0011] Optionally, the first driving device includes a first rack, a second rack, a gear, and a first motor. One end of the first rack is hinged to the first air guide plate, and one end of the second rack is slidably connected to the first air guide plate and the first rack. The gear meshes with the first and second racks to drive the first and second racks to move, causing the first air guide plate to move from the first position to the second position. The first motor is located on the side of the indoor unit of the air conditioner and is driven by the gear to provide driving force for the rotation of the gear.

[0012] Optionally, the first rack is provided with a first tooth portion, and the second rack is provided with a second tooth portion; the tooth pitch of the first tooth portion and the second tooth portion is the same.

[0013] Optionally, both the first rack and the second rack are arc-shaped.

[0014] Optionally, the indoor unit of the air conditioner further includes a second driving device, which is disposed on both sides of the second air guide plate and drivenly connected to the second air guide plate. The second driving device is used to drive the second air guide plate to rotate.

[0015] Optionally, the second driving device includes a second motor, which is fixedly mounted on the side of the indoor unit of the air conditioner, and the drive shaft of the second motor is located inside the rotating shaft of the second air guide plate.

[0016] Optionally, the indoor unit of the air conditioner further includes swivel blades, which are disposed inside the second air guide plate and are used for lateral airflow.

[0017] In some embodiments, the air conditioner includes the above-described indoor unit, and the air conditioner includes a first operating mode and a second operating mode; in the first operating mode, the second air guide plate sends air upward at an angle, and the first air guide plate is located at the second position; in the second operating mode, the second air guide plate sends air downward at an angle, and the first air guide plate is located at the second position.

[0018] The air conditioner indoor unit and air conditioner provided in this disclosure can achieve the following technical effects:

[0019] The air conditioner indoor unit provided in this embodiment includes a first air guide plate and a second air guide plate. The first air guide plate has a first position with the air outlet closed and a second position with the air outlet open for air intake. The second air guide plate guides air vertically at the air outlet, and the second position of the first air guide plate is located below the air conditioner indoor unit. By setting two air guide plates, the first air guide plate guides the indoor airflow to the vicinity of the air outlet, where it merges with the airflow blown from the heat exchanger and blows towards the user. The second air guide plate adjusts the direction of the airflow, thus improving the gentleness and comfort of the airflow from the air conditioner. An air intake channel is formed between the first air guide plate and the lower casing of the air conditioner indoor unit, i.e., the air intake channel is located outside the air conditioner indoor unit. Compared with the related technology of setting air intakes on the air outlet duct wall, this application does not cause a loss of airflow and therefore does not affect the energy efficiency of the air conditioner.

[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] This disclosure provides an air conditioner.

[0042] The air conditioner provided in this embodiment is a gentle, uniform air conditioner, including the indoor unit described below. A first air guide plate 10 forms an air-guiding channel outside the indoor unit, guiding indoor airflow to the vicinity of the air outlet, where it mixes with the airflow blown from the heat exchanger before being blown towards the user. This prevents the airflow from the heat exchanger from directly blowing onto the user, providing comfort for the user. Furthermore, the gentle airflow process does not result in a loss of airflow from the heat exchanger, nor does it affect the air conditioner's energy efficiency.

[0043] When in induced draft mode, the first air guide plate 10 is located below the indoor unit of the air conditioner and behind the air outlet. This ensures that the first air guide plate 10 does not obstruct the airflow from the heat exchanger and does not affect the air supply of the air conditioner. Simultaneously, the airflow from the heat exchanger does not blow directly onto the first air guide plate 10, preventing condensation from forming on its surface and improving the user experience.

[0044] Optionally, the air conditioner includes a first operating mode and a second operating mode; in the first operating mode, the second air guide plate 50 sends air upward at an angle, and the first air guide plate 10 is located in a second position; in the second operating mode, the second air guide plate 50 sends air downward at an angle, and the first air guide plate 10 is located in a second position.

[0045] Optionally, the first operating mode can be a cooling mode. In cooling mode, the second air guide plate 50 sends air upward at an angle, and the first air guide plate 10 is located at the air intake position below the air conditioner. The cold airflow blown out from the heat exchanger is blown upward at an angle along the second air guide plate, mixes with the air intake airflow near the air outlet, and is then blown into the room, so that the indoor temperature drops steadily, avoiding the discomfort caused to the user by a sudden drop in indoor temperature.

[0046] Optionally, the second operating mode can be a heating mode. In heating mode, the second air guide plate 50 sends air downwards at an angle, and the first air guide plate 10 is located at the air intake position below the air conditioner. The hot airflow blown out from the heat exchanger is blown downwards along the second air guide plate 50, mixes with the air intake airflow near the air outlet, and is then blown into the room, so that the room temperature rises steadily, while avoiding the hot airflow blowing directly downwards on the user and causing discomfort.

[0047] This disclosure also provides an indoor unit for an air conditioner, such as... Figures 1 to 9 As shown.

[0048] In some embodiments, the indoor unit of the air conditioner includes a housing with an air outlet, and also includes a first air guide plate 10 and a second air guide plate 50. The first air guide plate 10 has a first position with the air outlet closed and a second position with the air outlet open for air intake. The second air guide plate 50 is disposed inside the air outlet for vertical air intake. When the first air guide plate 10 is in the first position, it is located outside the second air guide plate 50. When the first air guide plate 10 is in the second position, it is horizontally positioned below the indoor unit of the air conditioner.

[0049] The air conditioner indoor unit provided in this embodiment includes a first air guide plate 10 and a second air guide plate 50. The first air guide plate 10 has a first position with the air outlet closed and a second position with the air outlet open for air intake. The second air guide plate 50 guides air vertically at the air outlet, and the second position of the first air guide plate 10 is located below the air conditioner indoor unit. By setting two air guide plates, the first air guide plate 10 guides the airflow in the room to the vicinity of the air outlet, where it merges with the airflow blown from the heat exchanger and blows towards the user. The second air guide plate 50 adjusts the direction of the airflow, thus improving the gentleness and comfort of the airflow from the air conditioner. An air intake channel is formed between the first air guide plate 10 and the lower casing of the air conditioner indoor unit, i.e., the air intake channel is located outside the air conditioner indoor unit. Compared with the related technology of setting air intakes on the air outlet duct wall, this application does not cause a loss of airflow and therefore does not affect the energy efficiency of the air conditioner.

[0050] Optionally, when the first air guide plate 10 is in the second position, the distance between the first air guide plate 10 and the lower casing of the indoor unit of the air conditioner is greater than 30mm.

[0051] In this embodiment, the first air guide plate 10 functions to guide airflow. When the air conditioner is turned on, the first air guide plate 10 moves from a first position to a middle position, and then to a second position. The first air guide plate 10 will not rotate or flip in the horizontal second position. In the horizontal state, the first air guide plate 10 has a preset distance from the lower casing of the air conditioner. It is understood that when the preset distance is small, some airflow noise may be generated between the first air guide plate 10 and the lower casing of the indoor unit of the air conditioner, and it will not be able to guide airflow effectively. Setting the preset distance to greater than 30 mm allows the first air guide plate 10 to have a better airflow effect, and no other noise will be generated during the airflow process. For example, the preset distance can be 40 mm, 50 mm, 60 mm, or 100 mm, etc.

[0052] Optionally, when the first air guide plate 10 is in the second position, the upper edge of the first air guide plate 10 is located behind the air outlet.

[0053] The upper edge of the first air guide plate 10 refers to the end near the upper edge of the air outlet when the first air guide plate 10 is in the first position (closed state). In the second position, the upper edge of the first air guide plate 10 is located behind the air outlet and below the indoor unit of the air conditioner. That is, the first air guide plate 10 is horizontally positioned below and behind the air outlet. This ensures that when the air conditioner blows air downwards, the first air guide plate 10 will not obstruct the downward airflow from the air outlet, thus not affecting the cooling or heating effect of the air conditioner. Simultaneously, the airflow from the heat exchanger will not blow directly onto the first air guide plate 10, preventing condensation from forming on its surface and improving the user experience.

[0054] Optionally, the indoor unit of the air conditioner also includes a first driving device, which is disposed on both sides of the indoor unit of the air conditioner and is movably connected to the first air guide plate 10. The first driving device is used to drive the first air guide plate 10 to move to a horizontal state.

[0055] Understandably, the first driving device is located at both ends of the first air guide plate 10 and is movably connected to both ends of the first air guide plate 10. The first driving devices at both ends of the first air guide plate 10 move synchronously, driving the first air guide plate 10 from the first position to the second position.

[0056] Optionally, the first driving device includes a first rack 20, a second rack 30, a gear 40, and a first motor. One end of the first rack 20 is hinged to the first air guide plate 10, and one end of the second rack 30 is slidably connected to the first air guide plate 10 and the first rack 20. The gear 40 meshes with the first rack 20 and the second rack 30 to drive the first rack 20 and the second rack 30 to move, so that the first air guide plate 10 moves from a first position to a second position. The first motor is located on the side of the indoor unit of the air conditioner and is drivenly connected to the gear 40 to provide driving force for the rotation of the gear 40.

[0057] Driven by the first motor, the gear 40 rotates and meshes with the first rack 20 and the second rack 30, driving the first air guide plate 10 to extend from the first position to the middle position, and then rotating it to the second position. In the second position, the first air guide plate 10 directs indoor airflow to the vicinity of the air outlet, forming an airflow channel between the inner side of the first air guide plate 10 and the lower casing of the indoor unit. Near the air outlet, the indoor airflow mixes with the airflow blown out by the heat exchanger, making the airflow from the indoor unit gentler and preventing hot or cold air from the heat exchanger from directly blowing onto the user and causing discomfort. Furthermore, the airflow from the heat exchanger does not directly blow onto the first air guide plate 10, preventing condensation from forming on its surface.

[0058] Optionally, the first rack 20 is provided with a first tooth 21, and the second rack 30 is provided with a second tooth 31; the tooth pitch of the first tooth 21 and the second tooth 31 is the same.

[0059] In this embodiment, the first tooth 21 and the second tooth 31 are arranged side by side, and the tooth pitch of the first tooth 21 and the second tooth 31 is the same. In this way, the first tooth 21 and the second tooth 31 can mesh synchronously with the same driving element, so that the first rack 20 and the second rack 30 move synchronously and drive the first air guide plate 10 to move.

[0060] Optionally, when the first air guide plate 10 is closed in the first position, the starting end of the first tooth 21 and the starting end of the second rack 30 are on the same starting line, and the number of teeth of the first tooth 21 is less than the number of teeth of the second tooth 31.

[0061] It is understandable that the starting ends of the first tooth 21 and the second tooth 31 are on the same starting line, the number of teeth of the first tooth 21 is less than the number of teeth of the second tooth 31, and the tooth pitch of the first tooth 21 and the second tooth 31 is the same. That is, the length of the first tooth 21 arranged on the first rack 20 is less than the length of the second tooth 31 arranged on the second rack 30.

[0062] With the first air guide plate 10 closed, the starting ends of the first tooth 21 and the second tooth 31 are on the same starting line, that is, the first tooth 21 and the second tooth 31 have the same starting end position. The gear 40 meshes with the first tooth 21 and the second tooth 31 along their starting ends, driving the first rack 20 and the second rack 30 to move synchronously until the gear 40 is at the end of the first tooth 21. After that, the gear 40 stops meshing with the first rack 20, the first rack 20 stops moving, and the gear 40 continues to mesh with the second tooth 31, driving the second rack 30 to move. Relative movement occurs between the first rack 20 and the second rack 30, causing the first air guide plate 10 to rotate to a horizontal second position.

[0063] In this embodiment, gear 40 first drives the first rack 20 and the second rack 30 to move synchronously, causing the first air guide plate 10 to extend from the air conditioner to the middle position. Then, gear 40 only drives the second rack 30 to move, causing the first air guide plate 10 to rotate from the middle position to a horizontal state. The middle position is the position where the first air guide plate 10 extends from the indoor unit of the air conditioner when gear 40 is at the end of the first tooth 21. Figure 7 As shown.

[0064] Optionally, both the first rack 20 and the second rack 30 are arc-shaped.

[0065] Understandably, the first air guide plate 10 has moving components at both ends. These components simultaneously move the first air guide plate 10 from a first position (closed) to a second position below the air conditioner. The first rack 20 and the second rack 30 are arc-shaped, which shortens the travel distance of the first air guide plate 10 from the first position to the second position below the air conditioner, allowing it to reach the preset horizontal state as quickly as possible. Furthermore, the arc-shaped rack occupies less space on the side of the indoor unit, making it compatible with more types of air conditioners.

[0066] Optionally, the center of the circle containing the first rack 20 and the center of the circle containing the second rack 30 coincide on the same projection plane.

[0067] It is understandable that both the first rack 20 and the second rack 30 are arc-shaped, and the center of the circle containing the first rack 20 and the center of the circle containing the second rack 30 coincide on the same projection plane, that is, the first rack 20 and the second rack 30 have the same degree of curvature. In this way, the first rack 20 and the second rack 30 can be driven by the same driving element to first synchronously drive the first air guide plate 10 to extend out of the air conditioner, and then the first rack 20 and the second rack 30 slide to generate relative motion, thereby driving the first air guide plate 10 to rotate to a horizontal state.

[0068] In this configuration, a sliding cavity 23 is provided on one side of the first rack 20, and a slider 34 is provided on the corresponding side of the second rack 30. The slider 34 is slidably disposed within the sliding cavity 23.

[0069] In this embodiment, the first rack 20 and the second rack 30 are arranged side by side and slidably connected. The upper surfaces of both the first rack 20 and the second rack 30 are provided with teeth. A sliding cavity 23 is provided on the opposite side of the first rack 20 and the second rack 30. Correspondingly, a slider 34 is provided at the corresponding position of the second rack 30. When the first rack 20 and the second rack 30 move relative to each other, the slider 34 slides within the sliding cavity 23. That is, during the process of the first guide vane 10 moving from the middle position to a horizontal state, the first rack 20 stops moving, and the second rack 30 moves relative to the first rack 20. Specifically, the slider 34 of the second rack 30 slides within the sliding cavity 23 of the first rack 20, so that the second rack 30 continues to mesh with the gear 40 in a preset direction. The first rack 20 and the second rack 30 are slidably connected in the manner described above, which enables the second rack 30 to still move along the preset track when it is engaged with the gear 40, preventing the second rack 30 from derailing and improving the reliability of the movement of the first rack 20 and the second rack 30 in this application.

[0070] Optionally, the bottom surface of the sliding cavity 23 extends towards the side near the second rack 30 and covers the lower surface of the second rack 30. In this way, the slider 34 on one side of the second rack 30 is inside the sliding cavity 23, and the lower surface of the second rack 30 abuts against the bottom surface of the sliding cavity 23, further defining the direction of movement of the second rack 30 relative to the first rack 20 and improving the reliability of the movement of the second rack 30.

[0071] Optionally, the motion mechanism for the first air guide plate 10 further includes a drive housing, which is fixed to the side of the air conditioner, and the first rack 20 and the second rack 30 are slidably disposed within the drive housing. Slider blocks are provided on the sides of both the first rack 20 and the second rack 30, and sliding grooves are provided on both sides of the drive housing, with the sliders slidably disposed within the grooves.

[0072] By setting a groove in the drive housing, the movement direction of the first rack 20 and the second rack 30 under the transmission of the gear 40 is further defined, so that the first rack 20 and the second rack 30 can first drive the first air guide plate 10 to the middle position according to the preset path, and then the second rack 30 slides under the joint limitation of the groove in the drive housing and the sliding cavity 23 of the first rack 20, driving the first air guide plate 10 to rotate to a horizontal state.

[0073] Optionally, the first rack 20 includes a first connecting shaft 22, which is vertically disposed on the side of the first rack 20. The first connecting shaft 22 is used to hinge with the first air guide plate 10 to provide a fulcrum for rotation when the first air guide plate 10 moves to a second position in a horizontal state.

[0074] One end of the first rack 20 is movably connected to the first air guide plate 10; specifically, the connection between the first rack 20 and the first air guide plate 10 is a hinge. A first connecting shaft 22 is provided on one side of one end of the first rack 20. The first connecting shaft 22 is cylindrical and vertically disposed on the side of the first rack 20. During the movement of the first air guide plate 10 from its intermediate position to a horizontal state, the first air guide plate 10 rotates around the first connecting shaft 22 as a fulcrum. In this embodiment, the axis of rotation of the first air guide plate 10 is the line connecting the two hinge points between the two ends of the first air guide plate 10 and the first connecting shaft 22.

[0075] Optionally, a first mounting base 11 is provided at one end of the first air guide plate 10, and a mounting hole 111 is provided on the first mounting base 11. The mounting hole 111 is hinged to the first connecting shaft 22. Optionally, the mounting hole 111 is a round hole, and the diameter of the mounting hole 111 is the same as the outer diameter of the first connecting shaft 22, so as to fit the first connecting shaft 22 and make the first rack 20 hinged to the first air guide plate 10.

[0076] Optionally, the second rack 30 includes a bent section 32 and a second connecting shaft 33. The bent section 32 is disposed on one end of the second rack 30 near the air outlet. The second connecting shaft 33 is disposed on the free end of the bent section 32 and is used to slide with the first air guide plate 10.

[0077] One end of the second rack 30 is movably connected to the first air guide plate 10; specifically, the connection between the second rack 30 and the first air guide plate 10 is a sliding connection. A bent section 32 is provided at the end of the second rack 30 connected to the first air guide plate 10. The bent section 32 extends in a direction away from the bending direction of the second rack 30, that is, it extends outward from the second rack 30. The outer side of the second rack 30 refers to the outside of the circle in which the second rack 30 is located. The structure of the second rack is as follows... Figure 9 As shown.

[0078] Optionally, a second mounting base 12 is also provided at one end of the first air guide plate 10. The first mounting base 11 and the second mounting base 12 are arranged side by side. A slide rail 121 is provided on the second mounting base 12, and the second connecting shaft 33 is slidably disposed in the slide rail 121.

[0079] Optionally, the slide 121 is straight, and the width of the slide 121 is equal to the outer diameter of the second connecting shaft 33. In this way, when the first air guide plate 10 rotates from the middle position to the horizontal state, the second connecting shaft 33 can slide within the slide 121, allowing the first air guide plate 10 to rotate about the first connecting shaft 22 as a fulcrum.
