Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a panel structure, indoor unit, air conditioner, and control method. Background Technology

[0002] As a machine that changes the temperature and humidity of a space, the efficiency of air conditioning in changing these parameters is particularly important. Currently, in the structure of an air conditioner, the control panel and the air guide plate are two independent but complementary parts. The air guide plate can only guide the airflow within a small area, while the control panel cannot be opened to increase the air intake, resulting in a limited functionality. Summary of the Invention

[0003] The purpose of this invention is to provide a panel structure, indoor unit, air conditioner and control method to solve the technical problem of the single function of the panel and air guide plate in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] In a first aspect, the present invention provides a panel structure comprising a panel, a partition, an air guide plate, a first adjustment component, and a second adjustment component, wherein:

[0006] The panel and the partition are arranged sequentially from the outside to the inside on the air outlet device;

[0007] The first adjustment component is connected to the panel and the partition respectively, so as to drive the panel and the partition to move synchronously, so as to open to different angles or close relative to the air outlet device;

[0008] The air guide plate is arranged inside the panel and located at the air outlet;

[0009] The second adjustment component is connected to the air guide plate to drive the air guide plate to open to different angles or close relative to the air outlet device;

[0010] By controlling the panel, the partition, and the air guide plate to open to different angles relative to the air outlet device, different operating states of the air outlet device can be switched.

[0011] Furthermore, the first adjustment component includes:

[0012] The bottom of the panel and the bottom ends of the partition are rotatably connected to the air outlet device via the hinge.

[0013] The power box device is used to movably connect the top of the panel and the top of the partition to the air outlet device. The power box device can control the top of the panel and the partition to move closer to or further away from the air outlet device, thereby realizing the synchronous opening or closing of the panel and the partition.

[0014] Furthermore, the power box device includes:

[0015] Box body;

[0016] The first motor is fixed to the housing;

[0017] The roller is connected to the output shaft of the first motor;

[0018] A thin rope, one end of which is connected to the roller, and the other end is split in two and connected to the panel and the partition respectively.

[0019] Furthermore, the two ends of the thin rope are of different lengths, including a long segment and a short segment. The long segment is connected to the panel, and the short segment is connected to the partition.

[0020] Furthermore, the bottom of the partition is located above the air outlet.

[0021] Furthermore, the second adjustment component includes:

[0022] The second motor is connected to one end of the air guide plate;

[0023] The other end of the air guide plate is rotatably connected to the air outlet device via the pin.

[0024] The panel structure provided by this invention, by changing the opening direction of the panel and using a motor, thin rope, and rollers to form a power box device, allows the panel to open while the air conditioner is running, thereby improving the efficiency of the air conditioner in changing the temperature and humidity of the space. The panel structure design includes an air guide plate that can block air in both forward and reverse directions. Forward blocking allows cold air to blow upwards, while reverse blocking allows warm air to blow downwards. The air guide plate in the panel can block air in both directions, which can ensure the self-cleaning of the air guide plate to a certain extent. Through the above structural settings, not only are the functions of the air guide plate and the panel enriched, but also the switching of different operating states is realized by adjusting the opening angle of the panel structure.

[0025] Secondly, the present invention provides an indoor unit, comprising a panel body, a cross-flow fan blade, and the panel structure; the panel body is installed on the front side of the indoor unit; the cross-flow fan blade is installed inside the indoor unit; and the panel structure is installed on the panel body.

[0026] Furthermore, the indoor unit has four operating states, namely:

[0027] In normal hot and cold conditions, the panel and the partition are closed, and the air guide plate is driven by the second adjustment component to guide air;

[0028] In enhanced cooling mode, the panel and the partition are opened to the first position, and the air guide plate is opened to a position parallel to the panel to block the wind.

[0029] In enhanced heating mode, the panel and the partition are opened to the first position, and the air guide plate is opened beyond the panel position to block the airflow in the opposite direction.

[0030] In self-cleaning mode, the panel and the partition are opened to the second position, and the air guide plate is opened to a position parallel to the panel for positive wind blocking; the angle of the second position is smaller than the angle of the first position.

[0031] The indoor unit provided by this invention changes the opening and closing method of the panel, allowing the panel to open and close during air conditioner operation. When the panel is in the open state during air conditioner operation, the panel body and filter screen inside the air conditioner are exposed. At this time, the air intake efficiency of the air conditioner is greatly improved, thereby improving the cooling and heating efficiency of the air conditioner, increasing the efficiency of the air conditioner in changing the temperature and humidity of the space, enabling the designated space to reach the required temperature and humidity conditions more quickly, and improving the user experience.

[0032] Thirdly, the present invention provides an air conditioner including the indoor unit.

[0033] Fourthly, the present invention provides a control method for switching the operating state of an air conditioner using the panel structure, comprising:

[0034] The operating status command is obtained based on the user's pressing action on the remote control;

[0035] Based on the acquired operating status commands, the control panel, partition, and air guide plate open to different positions to achieve the air conditioner's regular cold and hot air output, enhanced cooling for the upper air output, enhanced heating for the lower air output, or self-cleaning for the return air output.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0047] To improve the air intake of the air conditioner, thereby further enhancing the efficiency of changing the temperature and humidity of the space and improving its competitiveness, this invention designs a panel structure that is both a panel and an air guide plate, so as to improve the air conditioner's ability to change the temperature and humidity of the space.

[0048] like Figure 1 and Figure 2 As shown, the present invention provides a panel structure. Specifically, the panel structure in this embodiment is applied to the indoor unit of an air conditioner, that is, the air outlet device is the indoor unit. The air outlet device described below will be the indoor unit as an example.

[0049] In this embodiment, the panel structure includes a panel 1, a partition 15, an air guide plate 2, a first adjustment component, and a second adjustment component, wherein:

[0050] Panel 1 and partition 15 are arranged sequentially from the outside to the inside on the indoor unit; for example Figure 1 As shown, further, panel 1 is located on the front side of the indoor unit, and the specifications of panel 1 are the same as those of the front side of the indoor unit; a notch is provided in the middle of the lower part of panel 1, which is used to accommodate the air guide plate 2, so that when the indoor unit is closed, panel 1 and air guide plate 2 together form the front panel of the indoor unit.

[0051] The first adjustment component is connected to the panel 1 and the partition 15 respectively, so as to drive the panel 1 and the partition 15 to move synchronously, so as to open to different angles or close relative to the indoor unit; when the panel 1 and the partition 15 open synchronously relative to the indoor unit, they can open the airflow inlet of the cross-flow fan 8 located inside the indoor unit, so that a large amount of airflow can enter the cross-flow fan 8 through the opening between the panel 1, the partition 15 and the indoor unit, thereby increasing the air intake and improving the cooling and heating effect of the indoor unit.

[0052] The air guide plate 2 is arranged in the notch of the panel 1 and is located at the air outlet of the indoor unit;

[0053] The second adjustment component is connected to the air guide plate 2 to drive the air guide plate 2 to open to different angles or close relative to the indoor unit; when the air guide plate 2 is open relative to the indoor unit, it can guide the air blown out of the air outlet to different areas and different angles.

[0054] like Figure 2 As shown, in this embodiment, the indoor unit has a panel 14 on the front side, and the air outlet is located at the lower part of the panel 14. The panel 1, the partition 15, and the air guide plate 2 are fixed to the panel 14 by the first adjustment component and the second adjustment component, respectively, so that they can be opened when they are away from the panel 14, or closed when they are close to it.

[0055] By opening the control panel 1, partition 15, and air guide plate 2 to different angles relative to the indoor unit, the different operating states of the indoor unit can be switched.

[0056] like Figure 2 , 4 As shown in Figures 5 and 6, it should be noted that by opening the control panel 1, partition 15, and air guide plate 2 to different angles relative to the indoor unit, including angle control between panel 1 and the indoor unit, angle control between partition 15 and the indoor unit, angle control between air guide plate 2 and the indoor unit, and angle control between panel 1, partition 15, and air guide plate 2, when panel 1, partition 15, and air guide plate 2 are rotated to different angles, airflow channels in different directions will be formed, thereby realizing the switching of different operating states of the indoor unit.

[0057] like Figures 1-7 As shown, further, the first adjustment component includes:

[0058] The bottom of panel 1 and the bottom ends of partition 15 are rotatably connected to the indoor unit via hinges. In this embodiment, the hinge is a panel hinge 11, which is located on both sides of the bottom of panel 1. The hinge mating structure is installed on panel body 14, and the panel hinge 11 and the hinge mating structure are assembled together to realize the rotation of panel 1.

[0059] The power box device is movably connected to the indoor unit at both ends of the top of the panel 1 and the top of the partition 15. The power box device can control the top of the panel 1 and the partition 15 to move closer to or further away from the indoor unit, thereby realizing the synchronous opening or closing of the panel 1 and the partition 15.

[0060] Specifically, in this embodiment, the two power box devices are installed at the upper left and upper right corners of the panel 14, respectively.

[0061] like Figure 7 As shown, the power box device further includes:

[0062] Box 7;

[0063] The first motor 6 is fixed on the box 7;

[0064] The first motor 6 passes through the hole in the housing 7 and its output shaft is connected to the roller 5, so that the roller 5 is driven by the first motor 6.

[0065] The thin rope 4 is connected at one end to the hanging hole in the roller 5, and the other end is split into two and connected to the panel 1 and the partition 15 respectively.

[0066] In order to achieve synchronous operation between panel 1 and partition 15 while maintaining different angles between them, in this embodiment, the thin rope 4 is divided into two sections of different lengths, including a long section and a short section. The long section is connected to panel 1, and the short section is connected to partition 15 (that is, the section connecting to partition 15 is the shorter of the two sections of thin rope, and the section connecting to panel 1 is the longer of the two sections of thin rope). When the first motor 6 is running, the roller 5 can be rotated to realize the opening and closing of panel 1 and partition 15.

[0067] Furthermore, the string 4 is an elastic string that can withstand a certain degree of elongation and return to its original shape after the external force is removed.

[0068] To facilitate installation, in this embodiment, a panel hook 3 is provided on the panel 1, and a hook post 13 is provided at the end of the thin rope 4. During installation, the hook post 13 is inserted into the panel hook 3 to connect the two.

[0069] The hook post 13 is fixedly connected to the thin rope 4, and the panel hook 3 is a structural feature on the panel 1. The hook post 13 is engaged with the panel hook 3, allowing the panel 1 to be opened and closed by the control of the thin rope 4. The partition 15 is a solid structure that separates the air intake and air outlet areas of the indoor unit, ensuring that the air intake and air outlet of the indoor unit do not affect each other.

[0070] Furthermore, in order to avoid the partition 15 blocking the upward airflow, in this embodiment, the bottom of the partition 15 is located above the air outlet. Thus, the air blown out of the air outlet can be blown out through the opening between the panel 1 and the partition 15 after being blocked by the air guide plate 2, forming an upward airflow working mode.

[0071] like Figure 2 , Figure 4 , Figure 5 As shown, the second adjustment component further includes:

[0072] The second motor 10, and one end of the air guide plate 2 is connected to the second motor 10;

[0073] Pin 9, the other end of the air guide plate 2 is rotatably connected to the indoor unit via pin 9.

[0074] Specifically, for ease of installation, two panel body protrusions 12 are formed on the panel body 14, similar to a lifting lug structure; a second motor 10 is installed on one side of the panel body protrusion 12, and the second motor 10 is connected to the air guide plate 2 to control the rotation of the air guide plate 2; a rotating hole is provided on the other side of the panel body protrusion 12, and a pin 9 is rotatably installed in the rotating hole, thereby realizing the overall rotation of the air guide plate 2 when one side is driven.

[0075] The panel structure provided by this invention, by changing the opening direction of the panel and using a motor, thin rope, and rollers to form a power box device, allows the panel to open while the air conditioner is running, thereby improving the efficiency of the air conditioner in changing the temperature and humidity of the space. The panel structure design includes an air guide plate that can block air in both forward and reverse directions. Forward blocking allows cold air to blow upwards, while reverse blocking allows warm air to blow downwards. The air guide plate in the panel can block air in both directions, which can ensure the self-cleaning of the air guide plate to a certain extent. Through the above structural settings, not only are the functions of the air guide plate and the panel enriched, but also the switching of different operating states is realized by adjusting the opening angle of the panel structure.

[0076] like Figure 1 and Figure 2 As shown, the present invention provides an indoor unit including a panel body 14, a cross-flow fan blade 8, and a panel structure; the panel body 14 is installed on the front side of the indoor unit; the cross-flow fan blade 8 is installed inside the indoor unit; and the panel structure is installed on the panel body 14.

[0077] Furthermore, the indoor unit has four operating states, namely:

[0078] In normal heating and cooling conditions, when the panel structure is in this state, it appears no different from a traditional air conditioner; panel 1 and partition 15 are closed, and the air guide plate 2 is driven by the second adjustment component to guide airflow; at this time, as Figure 3 As shown, the air guide plate 2 swings, and the air blown out of the air outlet is guided to different areas through the air outlet duct formed between the air guide plate 2 and the panel 1. This is the operating mode of a conventional air conditioner. The present invention also has three other operating states, including:

[0079] Enhanced cooling: When the panel structure is in this state, the cold air blown from the cross-flow fan 8 is guided upwards by the panel 1, achieving upward airflow; the panel 1 and partition 15 are opened to the first position, and the air guide plate 2 is opened to a position parallel to the panel 1 for positive airflow blocking; Figure 4 As shown, at this time, since the air guide plate 2 and the panel 1 are parallel, the air outlet channel between the air guide plate 2 and the panel 1 is closed. An upward-facing air outlet channel is formed between the panel 1, the air guide plate 2, and the partition 15. Because cold air flows downwards, the room is in a cooling state. Forming the air outlet channel in an upward-facing direction achieves the effect of cold air being blown out from the top, allowing the cold air to flow from top to bottom and quickly cool the indoor environment. Furthermore, the opening of the panel 1 and the partition 15 allows more airflow to enter the cross-flow fan blade 8, increasing the air intake and improving the cooling effect.

[0080] In enhanced heating mode, when the panel structure is in this state, the hot air blown out from the cross-flow fan 8 is guided downwards by the air guide plate 2 in the panel 1, achieving downward blowing of hot air; the panel 1 and partition 15 are opened to the first position, and the air guide plate 2 is opened beyond the position of the panel 1 to block the airflow in the opposite direction; such as Figure 5 As shown, at this time, because the rotation angle of the air guide plate 2 is greater than that of the panel 1, the upper part of the air guide plate 2 blocks the upper part of the air outlet, preventing airflow from entering the area between the panel 1 and the partition 15. The airflow from the air outlet is blocked by the air guide plate 2 and blown out from the lower part of the air outlet through the air outlet channel between the air guide plate 2 and the bottom of the panel 1. Since hot air will flow upward, the indoor unit is in heating mode at this time. By blowing the hot airflow downward and then letting it flow upward naturally, the indoor ambient temperature is increased more quickly. Moreover, the opening of the panel 1 and the partition 15 also allows more airflow to enter the cross-flow fan blade 8, increasing the air intake and improving the heating effect.

[0081] In this invention, the air guide plate 2 can guide air in both forward and reverse directions when the cooling and heating modes are enhanced. Because the air guide plate 2 can guide air in both forward and reverse directions, the cleanliness of the air guide plate 2 itself can be ensured.

[0082] In self-cleaning mode, when the panel is in self-cleaning mode, the blown air can ensure the self-cleaning of the inside of the panel and the front side of the panel to a certain extent; panel 1 and partition 15 are opened to the second position, and air guide plate 2 is opened to a position parallel to panel 1 for positive wind blocking; wherein, the angle of the second position is smaller than the angle of the first position. Figure 6 As shown, at this time, the opening angle of panel 1 and partition 15 is very small. Partition 15 can be in a closed state, while only panel 1 is opened at a small angle. At this time, an upward air outlet channel is formed in front of panel 1 and partition 15. Moreover, the air guide plate 2 is also rotated to a position parallel to panel 1, closing the air outlet channel between air guide plate 2 and panel 1. The cross-flow fan blade 8 is controlled to run at a high speed. The large air volume is blown out through the air outlet and then blown upward through the upward air outlet channel between panel 1 and partition 15. During the blowing process, the dust on the surface of panel 1 and the front surface of panel body 14 is blown away, realizing a micro self-cleaning function. The indoor unit provided by the present invention changes the opening and closing method of the panel, so that the panel can be opened and closed during the operation of the air conditioner. When the panel is in the open state during the operation of the air conditioner, the panel body and filter screen and other components inside the air conditioner are exposed. At this time, the air intake efficiency of the air conditioner is greatly improved, thereby improving the cooling and heating efficiency of the air conditioner, improving the efficiency of the air conditioner in changing the temperature and humidity of the space, enabling the specified space to reach the required temperature and humidity conditions more quickly, and improving the user experience.

[0083] The present invention provides an air conditioner, including the above-mentioned indoor unit.

[0084] The air conditioner provided by this invention adopts the above-mentioned panel structure design. Since the panel can be opened to the maximum extent to expose the interior of the indoor unit, air can enter the unit through the filter, thereby improving the efficiency of the air conditioner in changing the temperature and humidity of the space.

[0085] like Figure 8 As shown, the present invention provides a control method for switching the operating state of an air conditioner using a panel structure, comprising:

[0086] The operating status command is obtained based on the user's pressing action on the remote control;

[0087] Based on the acquired operating status commands, the control panel, partition, and air guide plate open to different positions to achieve the air conditioner's regular cold and hot air output, enhanced cooling for the upper air output, enhanced heating for the lower air output, or self-cleaning for the return air output.

[0088] Specifically, the control panel, partition, and air deflector are opened to different positions, including:

[0089] Remote control to turn on the indoor unit;

[0090] When the controller receives a signal from the remote control, etc., and the controller is in normal hot and cold mode, it keeps the panel 1 and the partition 15 closed. The second motor 10 drives the air guide plate 2 to swing relative to the notch of the panel 1 on the front side of the air outlet to achieve normal air guidance.

[0091] When the controller receives a signal from the remote control, etc., and the forced cooling mode is activated, it first identifies whether the first motor and the second motor are at the corresponding angular positions of panel 1 and the air guide plate. This should be the first position. If the first motor 6 is not in the corresponding position, that is, panel 1 and partition 15 are not in the corresponding first position, then the first motor 6 in both power box devices needs to be controlled to rotate simultaneously (forward rotation). The roller 5 rotates forward to release the thin rope 4, and panel 1 and partition 15 slowly open to the specified angle, that is, to rotate panel 1 and partition 15 to the first position. Figure 4 At this position, the thin rope 4 is fully extended to open panel 1 and partition 15 to their maximum angle, forming an upward-sloping air outlet channel between the outer side of the air guide plate 2 and the inner side of panel 1. At this time, panel 1 and partition 15 are open, and partition 15 separates the air inlet and outlet areas, ensuring that air inlet and outlet do not interfere with each other, thereby increasing the air intake and heat exchange efficiency of the air conditioner. When it is detected that the second motor 10 is not in the corresponding position, that is, when the air guide plate 2 is parallel to the extended panel 1, the second motor 10 drives the air guide plate... Plate 2 rotates to be parallel to panel 1. At this time, air guide plate 2 and panel 1 are approximately integrated. Panel 1 and air guide plate 2 work together to blow the cold air blown out from cross-flow fan 8 upwards. External airflow enters through the air intake channel between the inner side of partition 15 and panel 14, then passes through cross-flow fan 8, then through the air outlet, and then is blocked by the air guide plate 2, so that the airflow is blown out through the upward-sloping air outlet channel, forming a forced cooling mode of upward blowing. The first motor 6 and the second motor 10 rotate simultaneously to control the air guide plate 2 to rotate with panel 1 to achieve the air guiding function.

[0092] When the controller receives a signal from the remote control, etc., and the forced heating mode is activated, it first identifies whether the first motor and the second motor are at the corresponding angular positions of panel 1 and the air guide plate. This should be the first position. If the first motor 6 is not in the corresponding position, that is, panel 1 and partition 15 are not in the corresponding first position, then the first motor 6 in both power box devices needs to be controlled to rotate simultaneously (forward rotation). The roller 5 rotates forward to release the thin rope 4, and panel 1 and partition 15 slowly open to the specified angle, that is, to rotate panel 1 and partition 15 to the first position. Figure 5At this position, the thin rope 4 is fully extended to open the panel 1 and partition 15 to their maximum angle. When it is detected that the second motor 10 is not in the corresponding position, that is, the air guide plate 2 is made to exceed the position of the unfolded panel 1, so that the air guide plate 2 rotates to a larger angle, and the upper part of the air guide plate 2 blocks the channel between the partition 15 and the panel 1, forming a reverse windbreak. Specifically, the second motor 10 drives the air guide plate 2 to rotate (forward) so that it exceeds the panel 1, so that the panel 1 and the air guide plate 2 form an angle. At this time, the air guide plate 2 mainly plays the role of guiding the air, so that the hot air blown out from the cross-flow fan 8 blows downward, solving the problem of hot air not reaching the feet and the head being hot and the feet being cold. The external airflow enters through the air intake channel between the inner side of the partition 15 and the panel body 14, then passes through the cross-flow fan 8 and then through the air outlet, and then is blocked by the reverse wind of the air guide plate 2, so that the airflow is blown out through the downward-sloping air outlet channel, forming a forced heating mode of downward blowing.

[0093] When the controller receives a signal from the remote control, etc., and the self-cleaning mode is activated, it first identifies whether the first and second motors are in the corresponding angular positions of panel 1 and the air guide plate. At this point, they should be in the second position. If the first motor 6 is not in the corresponding position, that is, panel 1 and partition 15 are not in the corresponding second position, then the first motor 6 needs to be controlled to rotate to move panel 1 and partition 15 to the second position. Figure 6 At this position, the thin rope 4 is not fully unfolded, so that the panel 1 and the partition 15 are opened to a very small angle. The partition 15 can be attached to the panel body 14, and the opening angle is 0. The panel 1 is opened to a small angle. When it is detected that the second motor 10 is not in the corresponding position, that is, when the air guide plate 2 is in a parallel state with the unfolded panel 1, the second motor 10 drives the air guide plate 2 to rotate, so that it is parallel to the panel 1. The speed of the cross-flow fan blade 8 increases, and the air volume input is strengthened, which can wash away dust, particles and other substances inside the panel and on the front side of the panel body. This state can achieve a certain degree of self-cleaning effect. The high-speed airflow passes through the air outlet, then is blocked by the air guide plate 2, and finally blows out through the vertical upward air outlet between the panel 1 and the partition 15. During the flow, the dust on the front side of the panel body 14 and the inner side of the panel 1 is swept away, thus achieving self-cleaning.

[0094] It should be noted here that the direction of rotation mentioned throughout the text refers to the direction in which the thin rope 4 is wound off the roller 5, which is the direction in which the panel 1 rotates away from the panel body 14.

[0095] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
