Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner and an air guide plate thereof. Background Art

[0002] The air conditioner is used to regulate indoor air. The air conditioner shell has an air inlet and an air outlet, and a heat exchanger is arranged inside the shell. After the indoor air enters the shell through the air inlet, it exchanges heat with the heat exchanger to form cold air or hot air. The fan blows the cold air / hot air to the indoor environment through the air outlet.

[0003] However, indoor air often contains dust and other particles, which affect human health. Moreover, these particles will adhere to the surface of the heat exchanger, which is easy to emit odor when the air conditioner is running, especially in the initial startup.

[0004] There are many purification schemes designed in the prior art, including setting a purification module in the air conditioner housing, etc. However, the purification module also has many defects, such as occupying too much volume, having a complex structure, having a short service life, and being prone to secondary pollution, etc. Summary of the invention

[0005] The object of the present invention is to overcome at least one defect in the prior art and to provide an air guide plate for an air conditioner which has a simple and novel structure and a purification function and a corresponding air conditioner.

[0006] Another object of the present invention is to facilitate switching between the purification mode and the non-purification mode.

[0007] On the one hand, the present invention provides an air guide plate for installation at an air inlet or an air outlet of a housing of the air conditioner, wherein the air guide plate defines a purification chamber for accommodating a purification substance, and the purification chamber is connected to the external environment through an air inlet hole and an air outlet hole;

[0008] The air guide plate is configured to allow airflow to enter the purification chamber through the air inlet when the air inlet is at a purification angle that makes the air inlet face the air inlet or the air outlet, and then flow out through the air outlet after being purified by the purification substance.

[0009] Optionally, the air guide plate is rotatably mounted on the shell so as to be rotated to a non-purification angle so that the air inlet and the air outlet face away from the air flow direction of the air inlet or the air outlet to prevent the air flow from entering the purification chamber.

[0010] Optionally, a plurality of partitions are provided in the purification chamber to divide the purification chamber into a plurality of sub-chambers, and each of the partitions has a ventilation hole to allow airflow to penetrate the air inlet hole into one of the sub-chambers, and then enter the remaining sub-chambers through the ventilation holes of each of the partitions in sequence;

[0011] There are multiple air outlet holes, and each sub-chamber is matched with its own air outlet hole.

[0012] Optionally, the air guide plate includes a base plate and a cover plate, and the cover plate is buckled on the first side surface of the base plate to define the purification chamber.

[0013] Optionally, the cover plate includes a main body wall spaced apart from the first side surface, and a first end wall and a second end wall bent from both sides of the main body wall toward the base plate and extending to the first side surface, the first end wall and the second end wall are respectively close to the first side and the second side of the base plate, and the air inlet hole is opened in the first end wall;

[0014] Each of the partitions extends from the main body wall toward the first side surface;

[0015] The main body wall includes a plurality of opening sections, each of which is used to define one of the sub-chambers and is provided with the air outlet holes; and

[0016] The end of each opening segment close to the second side overlaps the outside of the end of its adjacent opening segment close to the first side, so that the outer surfaces of each opening segment together form a serrated shape, so that in the direction from the first side to the second side, each opening segment gradually extends away from the first side.

[0017] Optionally, the first end wall gradually inclines toward the first edge during the process of extending toward the first side surface.

[0018] Optionally, an arc transition is adopted between the main body wall and the second end wall.

[0019] On the other hand, the present invention also provides an air conditioner, comprising:

[0020] A housing having an air inlet and an air outlet; and

[0021] At least one air guide plate as described in any one of the above items, wherein the air guide plate is arranged at the air inlet or the air outlet.

[0022] Optionally, the air conditioner is wall-mounted;

[0023] There are multiple air guide plates, which are arranged front and back at the air inlet. Each air guide plate is rotatably mounted on the housing around its own axis, and the axis is parallel to the lateral direction of the air conditioner.

[0024] The air conditioner further comprises at least one driving mechanism, and each of the driving mechanisms is used to drive each of the air guide plates to rotate synchronously.

[0025] Optionally, a first gear is provided at the end of each of the air guide plates;

[0026] Each of the driving mechanisms includes a motor, a second gear and a synchronous belt. The second gear is installed on the motor. The synchronous belt is tensioned on and meshed with the first gear and the second gear. When the motor drives the second gear to rotate, the synchronous belt drives the first gear to rotate, thereby causing the air guide plates to rotate synchronously.

[0027] In the air guide plate and the corresponding air conditioner of the present invention, the air guide plate installed at the air inlet or the air outlet defines a purification chamber for accommodating the purification substance. When the air guide plate is at a purification angle, the air inlet airflow or the air outlet airflow enters the purification chamber to be purified by the purification substance. The present invention integrates the purification function of the air conditioner into the air guide plate, has a simple and ingenious structure, does not need to independently set up a purification module, and saves the cost of the air conditioner.

[0028] Furthermore, in the scheme of the present invention, when the indoor air is clean enough and does not need to be purified, the air guide plate can be rotated to a non-purification angle to prevent the inlet airflow or the outlet airflow from entering the purification chamber, so that it will not be purified. It can be seen that the present invention realizes the switching between the purification mode and the non-purification mode through the conventional rotation control of the air guide plate, and the function is complete and the control method is very simple.

[0029] Furthermore, the air guide plate of the present invention divides the purification chamber into a plurality of sub-chambers arranged in sequence along the airflow direction, so that the purified material is more dispersed, multiple purifications are achieved, and the airflow is more fully in contact with the purified material, avoiding the accumulation of purified materials resulting in an insufficient purification process.

[0030] Furthermore, the air guide plate of the present invention includes a base plate and a cover plate, and the first end wall of the cover plate with an air inlet is gradually inclined toward the first side during the process of extending toward the first side, so that when the air guide plate is installed at the air inlet on the top of the wall-mounted air conditioner, the top of the base plate is inclined forward and the first end wall is facing straight forward, which can not only guide the airflow in front of the air conditioner into the air inlet (the wall is behind the air conditioner), but also allow the airflow to enter the air inlet of the first end wall horizontally, so that the air intake is smoother, killing two birds with one stone. In addition, the present invention also makes the opening section with multiple air outlets into a serrated shape, so that when the air guide plate is at a non-purification angle, the outer surface of the opening section can deviate from the airflow direction to prevent the airflow from entering the purification chamber through the air outlet.

A person skilled in the art should be able to understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0046] The invention provides an air guide plate for an air conditioner and the air conditioner.

[0047] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners can form a vapor compression refrigeration cycle system consisting of an evaporator, condenser, compressor, throttling device, and other necessary components to output cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0048] The air conditioner of the present invention can be a household air conditioner or a central air conditioner. Specifically, the specific form of the air conditioner can be a split wall-mounted type, a split vertical type, an integral type, a patio type, etc. The embodiments of the present invention do not impose any restrictions on the specific form of the air conditioner. Figures 1 to 10 An embodiment of a wall-mounted air conditioner is illustrated.

[0049] The air conditioner of the embodiment of the present invention includes a shell. When the air conditioner is a split type, the shell refers to the shell of the indoor unit. The shell is provided with an air inlet and an air outlet. The air inlet is used to introduce indoor air, and the air outlet is used to discharge conditioned airflow (such as cold air, hot air). The air guide plate of the embodiment of the present invention is used to be installed at the air inlet or air outlet of the air conditioner. When the air guide plate is installed at the air inlet, its function is to guide the indoor air into the air inlet, and it can also be used to close the air inlet when the air conditioner is turned off, such as Figure 1 When the air guide plate is installed at the air outlet, its function is to guide the air outlet direction, and it can also be used to close the air outlet when the air conditioner is turned off.

[0050] Refer to the following Figures 1 to 10 The air conditioner and the air guide plate thereof according to the embodiment of the present invention are introduced in detail by taking a wall-mounted air conditioner as an example.

[0051] Figure 1 is a schematic diagram of an air conditioner according to an embodiment of the present invention when the air guide plate 20 is at a purification angle; Figure 2 yes Figure 1 A magnified image of point A; Figure 3 yes Figure 1 A schematic diagram of a partial structure of the air guide plate 20;

[0052] Figure 4 yes Figure 3 The schematic diagram of the cover plate 200 of the air guide plate 20 shown is viewed from the back; Figure 5 is a schematic cross-sectional view of the air guide plate 20 of the present invention; Figure 6 yes Figure 5 The wind direction of the wind deflector 20 is shown in the figure. The x-axis is parallel to the lateral direction of the air conditioner. Figure 5 The section plane is parallel to the front-back direction, that is, perpendicular to the x direction.

[0053] like Figures 1 to 6 As shown, the air guide plate 20 of the embodiment of the present invention defines a purification chamber 216 for accommodating purification substances. The purification substances are specifically aromatherapy materials, electrostatic adsorption materials, plasma purification materials, negative ion generating materials, ceramic activated carbon materials, and the like. The purification chamber 216 is connected to the external environment through the air inlet 201 and the air outlet 202. The air guide plate 20 is configured as follows: when it is at a purification angle such that the air inlet 201 is directed toward the air inlet 11 or the air outlet 12, the air flow is allowed to enter the purification chamber 216 through the air inlet 201, and after being purified by the purification substances, it flows out through the air outlet 202, as shown in FIG. Figure 1 , Figure 2 and Figure 6 Arrows indicate the direction of airflow.

[0054] In the embodiment of the present invention, the air guide plate 20 installed at the air inlet 11 or the air outlet 12 defines a purification chamber 216 for accommodating the purification substance. When the air guide plate 20 is at the purification angle, the air inlet airflow or the air outlet airflow enters the purification chamber 216 to be purified by the purification substance. The present invention integrates the purification function of the air conditioner into the air guide plate 20, has a simple and ingenious structure, does not need to independently set up a purification module, and saves the cost of the air conditioner.

[0055] Figure 7 yes Figure 1 The schematic diagram of the air conditioner shown is when the air guide plate 20 is at a non-purification angle; Figure 8 yes Figure 7 Enlarged view of point B.

[0056] In some embodiments, the air guide plate 20 can be rotatably mounted on the housing 10 so as to be rotated to a non-purification angle so that the air inlet 201 and the air outlet 202 are facing away from the air inlet 11 or the air outlet 12 to prevent the air flow from entering the purification chamber 216. Figure 7 and Figure 8 In this way, when the indoor air is clean enough and does not need to be purified, the air guide plate 20 can be rotated to a non-purification angle to prevent the inlet airflow or the outlet airflow from entering the purification chamber 216 and thus not being purified. It can be seen that the present invention realizes the switching between the purification mode and the non-purification mode through the conventional rotation control of the air guide plate 20, and the function is complete and the control method is very simple.

[0057] In some embodiments, Figure 5 and Figure 6 As shown, a plurality of partitions 250, 260 are provided in the purification chamber 216 to divide the purification chamber 216 into a plurality of sub-chambers 2161, 2162, 2163. Each sub-chamber 2161, 2162, 2163 is used to store the purified material. Each partition 250, 260 has a ventilation hole 203 to allow air flow to penetrate the air inlet 201 into a sub-chamber, and then enter the remaining sub-chambers through the ventilation holes 203 of each partition 250, 260 in sequence. There are a plurality of air outlet holes 202, and each sub-chamber 2161, 2162, 2163 is matched with its own air outlet hole 202.

[0058] Specifically, Figure 6 For example, after the airflow enters the most upstream sub-chamber 2161 from the air inlet 201, it is purified by the purified material in the sub-chamber 2161. Then, part of it is discharged through the air outlet 202, and the other part is discharged through the ventilation hole 203 ( Figure 6 The cross-section of is misaligned with the ventilation hole 203, so Figure 6 The airflow entering the subchamber 2162 is purified by the purified substances inside the subchamber 2162, and then a part of the airflow is discharged through the air outlet 202. The other part of the airflow enters the subchamber 2163 through the air outlet 203 of the partition plate 260, and then is purified by the purified substances inside the subchamber 2162, and then is discharged through the air outlet 202.

[0059] The air guide plate 20 of the embodiment of the present invention divides the purification chamber 216 into a plurality of sub-chambers 2161, 2162, and 2163 arranged in sequence along the airflow direction, so that the purified material is more dispersed, multiple purifications are achieved, and the airflow is more fully in contact with the purified material, avoiding the accumulation of purified materials and resulting in an insufficient purification process.

[0060] In some embodiments, Figures 3 to 5As shown, the air guide plate 20 may include a substrate 100 and a cover plate 200, and the cover plate 200 is buckled on the first side 101 of the substrate 100 to define a purification chamber 216. Specifically, a middle partition plate 270 may be provided between the substrate 100 and the cover plate 200 to separate the space between the substrate 100 and the cover plate 200 into two parts, one part of which constitutes the purification chamber 216. The substrate 100 may be in the shape of a flat plate, and the cover plate 200 may be in the shape of a shell. In this embodiment, the air guide plate 20 is designed as a split structure, which is convenient for the processing of parts and the molding of the purification chamber 216 on the one hand, and also convenient for placing purification substances into the purification chamber 216 on the other hand. The cover plate 200 and the substrate 100 may be connected in a detachable connection manner, including a snap connection, a threaded connection, etc., to facilitate disassembly, thereby facilitating the user to replace the purification substance.

[0061] Furthermore, if Figure 5 As shown, the cover plate 200 includes a main body wall 230 spaced apart from the first side surface 101, and a first end wall 210 and a second end wall 220 that are bent from both sides of the main body wall 230 toward the substrate 100 and extend to the first side surface 101. In addition, the cover plate 200 also includes two side walls 290, each of which is connected to one end of the main body wall 230, the first end wall 210, and the second end wall 220. The first end wall 210 and the second end wall 220 are respectively close to the first side C1 and the second side C2 of the substrate 100, and the air inlet 201 is opened in the first end wall 210. When the air guide plate 20 is at a purification angle, the first side C1 faces the incoming flow direction. When the air guide plate 20 is at a non-purification angle, the second side C2 faces the incoming flow direction. Each partition 250, 260 extends from the main body wall 230 toward the first side surface 101 and abuts against the first side surface 101. The main body wall 230 includes a plurality of opening sections 231, 232, 233, each of which is used to define a sub-chamber 2161, 2162, 2163 and is provided with an air outlet 202. The end of each opening section 231, 232, 233 close to the second side C2 is overlapped with the end of the adjacent opening section 231, 232, 233 close to the first side C1, so that the outer surfaces of each opening section 231, 232, 233 together form a sawtooth shape. Figure 5 The b end of the opening section 231 is close to the second side C2, and the b end is overlapped on the outside of the c end of the opening section 232. The d end of the opening section 232 is overlapped on the outside of the e end of the opening section 233.

[0062] Based on the above structure, the embodiment of the present invention makes the opening sections 231, 232, 233 with the air outlet holes 202 form a serrated shape, so that the outer surfaces of the opening sections 231, 232, 233 are retracted. When the air guide plate 20 is at a non-purification angle, the outer surfaces of the opening sections 231, 232, 233 can deviate from the airflow direction to prevent the airflow from entering the purification chamber 216 through the air outlet holes 202.

[0063] Furthermore, if Figure 5 As shown, the first end wall 210 gradually tilts toward the first side C1 during the process of extending toward the first side surface 101, so that when the air guide plate 20 is installed at the air inlet 11 at the top of the wall-mounted air conditioner, the top of the base plate 100 tilts forward and the first end wall 210 faces the front (as shown in FIG. Figure 1 ), which not only guides the airflow in front of the air conditioner into the air inlet 11 (there is a wall behind the air conditioner), but also enables the airflow to enter the air inlet hole 201 of the first end wall 210 horizontally, making the air intake smoother, thus killing two birds with one stone.

[0064] Furthermore, a circular arc transition can be used between the main wall 230 and the second end wall 220. When the air guide plate 20 is at a non-purification angle, the second end wall 220 faces the incoming flow direction, and after the airflow rushes toward the second end wall 220, it can leave the second end wall 220 more smoothly through the circular arc transition surface.

[0065] Another embodiment of the present invention provides an air conditioner, comprising a housing 10 and at least one air guide plate 20 according to any of the above embodiments, wherein the housing 10 is provided with an air inlet 11 and an air outlet 12 , and the air guide plate 20 is disposed at the air inlet 11 or the air outlet 12 .

[0066] In some embodiments, Figure 1 and Figure 7 As shown, the air conditioner is wall-mounted. There are multiple air guide plates 20, which are arranged front and back at the air inlet 11. Each air guide plate 20 is rotatably mounted on the housing 10 around its own axis, and the axis is parallel to the lateral direction of the air conditioner, that is, parallel to the x-axis. The air conditioner also includes at least one driving mechanism 30, each driving mechanism 30 is used to drive each air guide plate 20 to rotate synchronously.

[0067] The embodiment of the present invention guides the incoming air flow by setting an air guide plate 20 at the air inlet 11, so that the incoming air volume is larger. Moreover, when the air conditioner is turned off, the air inlet 11 can be closed by the air guide plate 20 to prevent dust from entering. There are multiple air guide plates 20 so that there are more purification chambers 216, and the distribution range of the air inlet holes 201 is larger, so that more incoming air flows enter the purification chambers 216 for purification. In addition, since the wall-mounted air conditioner is wall-mounted, the distance between the top and the ceiling is relatively close. The embodiment of the present invention sets more air guide plates 20, and also makes the width of each air guide plate 20 narrower, so that the air guide plate 20 is too wide and occupies too much space above the air conditioner, affecting the normal installation of the air conditioner.

[0068] Furthermore, if Fig. 9 and Fig.10As shown, a first gear 400 is provided at the end of each air deflector 20. Each driving mechanism 30 includes a motor 31, a second gear 32 and a synchronous belt 33. The synchronous belt 33 is a transmission belt having teeth on the inner side so as to mesh with the gears. The motor 31 is fixedly mounted inside the housing 10. The second gear 32 is mounted on the motor 31, and the synchronous belt 33 is stretched on and meshed with each first gear 400 and the second gear 32, so that when the motor 31 drives the second gear 32 to rotate, the synchronous belt 33 drives each first gear 400 to rotate, thereby causing each air deflector 20 to rotate synchronously.

[0069] Specifically, each driving mechanism 30 may further include a plurality of tensioning gears 34 , 35 , which are fixedly mounted on the housing 10 to tension (stretch) the synchronous belt 33 .

[0070] In some embodiments, Fig. 9 As shown, there are two driving mechanisms 30 , which are respectively used to drive the two ends of the air guide plate 20 in the length direction.

[0071] In some embodiments, after the wall-mounted air conditioner is turned on, each air guide plate 20 is rotated to a purification angle. The compressor and the indoor fan are turned on, and the compressor is operated at a fixed frequency. It is determined whether the hydrophilic oil film thickness d of the heat exchanger fins reaches the set thickness d0 that can prevent the emission of odor. If d<d0, it indicates that the oil film thickness is not enough, and the operation continues in the above manner. If d≥d0, it indicates that the oil film thickness is sufficient and no further purification is required. It is then determined whether a purification instruction is received. If so, the air guide plate 20 is kept at the purification angle, otherwise the air guide plate 20 is switched to a non-purification angle.

[0072] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
