Description

Technical Field

[0001] The utility model belongs to the technical field of air outlets of household appliances, and particularly relates to an air outlet device. Background Art

[0002] Among existing vertical air conditioners, vertically distributed cabinet air conditioners are widely used, and their air supply technology is becoming increasingly mature. Whether vertically distributed cabinet air conditioners or circular cabinet air conditioners with left-right air sweeping, the air intake method is the same: an air intake space is opened from the rear of the cabinet and a retractable filter is used to filter out large particles of impurities and dust in the air.

[0003] In order to continuously improve air intake and outlet technology and continuously innovate new products, research is currently underway to eliminate the need for rear air intake, where the air outlet can also serve as an air inlet. Specifically, a vertical air conditioner in the prior art has an upper air inlet, an upper air outlet, a lower air inlet, and a lower air outlet. When in cooling air outlet mode, air enters the lower air inlet, passes through the lower filter, and then enters the air duct, and then is sent upward through the upper air outlet; when in heating air outlet mode, air enters the upper air inlet, passes through the upper filter, and then enters the air duct, and then is sent downward through the lower air outlet. Regardless of whether the air is inlet from the rear or from top to bottom, users often ignore whether the filter is dirty or clogged. Over time, dust will accumulate, affecting the air volume and air quality. Therefore, it is necessary to clean the filter in a timely manner. Utility Model Content

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0055] See also Figure 1-7 As shown, according to an embodiment of the present invention, an air outlet device is provided, which includes a first air inlet 2, a first air outlet 1, a second air inlet 6, a second air outlet 23, a fan mechanism, and a liquid spray mechanism. The first air outlet 1 and the second air outlet 23 can both be opened and closed, for example, by air outlet guide plates. For example, the first air outlet 1 can be opened and closed by the first air guide plate 3, and the second air outlet 23 can be opened and closed by the second air guide plate 22.

[0056] The above-mentioned air outlet device has a first state and a second state. In the first state, the first air outlet 1 is open and the second air outlet 23 is closed. The fan mechanism drives air to flow in from the second air inlet 6 and out from the first air outlet 1. In the second state, the first air outlet 1 is closed and the second air outlet 23 is open. The fan mechanism drives air to flow in from the first air inlet 2 and out from the second air outlet 23.

[0057] The aforementioned air outlet device may include a first filter 8 for filtering the air entering the first air inlet 2, and the liquid spraying mechanism is used to spray a cleaning liquid onto the first filter 8. And / or, the aforementioned air outlet device may include a second filter 17 for filtering the air entering the second air inlet 6, and the liquid spraying mechanism is used to spray a cleaning liquid onto the second filter 17.

[0058] In the above example, since the liquid spraying mechanism can spray cleaning liquid such as water on the first filter 8 and the second filter 17, the first filter 8 and the second filter 17 can be cleaned, so that the first filter 8 and the second filter 17 can be kept clean.

[0059] In some embodiments, when the air outlet device includes a first filter 8, the first filter 8 is not removable and is located inside the air outlet device. Compared to the prior art method of cleaning by removing the filter, the first filter 8 can be cleaned by spraying a cleaning liquid with a liquid spray mechanism, thereby eliminating the need for filter removal and saving manpower.

[0060] Similarly, when the air outlet device includes a second filter 17, the second filter 17 is not removable and is located inside the air outlet device. Compared to the prior art method of removing the filter for cleaning, the second filter 17 can be cleaned by spraying a cleaning liquid through a liquid spraying mechanism, thereby eliminating the need for filter removal and saving manpower.

[0061] In some embodiments, as Figure 1 and Figure 2 As shown, the aforementioned air outlet device may have an air outlet 5, and the aforementioned second air outlet 23 discharges air through the air outlet 5 in the second state. The aforementioned second air inlet 6 takes in air through the air outlet 5 in the first state. Specifically, the aforementioned first air inlet 2 and first air outlet 1 are both arranged on one side of the air outlet device, and the air outlet 5 is arranged on the other side of the air outlet device. In a specific application example, the first air inlet 2 and the first air outlet 1 can both be arranged at the upper part of the air outlet device, and the air outlet 5 can be arranged at the lower part of the air outlet device, so that the air outlet device can discharge air in the first state and in the second state.

[0062] It should be noted here that the above-mentioned cleaning liquid can be water or the like.

[0063] In some embodiments, when the air outlet device includes a first filter 8, the aforementioned liquid spraying mechanism may include a first liquid spraying mechanism to spray the cleaning liquid onto the first filter 8 through the first liquid spraying mechanism. Figure 3-5 As shown, the first liquid spraying mechanism may include a first housing 12, a pump 13, and a first nozzle 9. The first housing 12 is used to contain a cleaning liquid, such as water. The pump 13 is used to pump the cleaning liquid in the first housing 12 to the first nozzle 9, so that the first nozzle 9 sprays the cleaning liquid onto the first filter 8. In a specific application example, the pump 13 may be a water pump, for example.

[0064] In the above example, the first box body 12 , the pump body 13 and the first nozzle 9 cooperate to realize the function of the first liquid spraying structure spraying the cleaning liquid onto the first filter 8 .

[0065] In some embodiments, as Figure 3 As shown, the aforementioned fan mechanism may include a first fan 25, which may be a centrifugal fan, etc. The fan mechanism can drive air into the second air inlet 6 and out of the first air outlet 1 through the first fan 25 in a first state. The fan mechanism can also drive air into the first air inlet 2 and out of the second air outlet 23 through the first fan 25 in a second state. The first housing 12 is annular and is mounted radially outside the first fan 25.

[0066] In the above example, by sleeve-mounting the first housing 12 radially outwardly of the first fan 25, the space radially outwardly of the first fan 25 can be fully utilized, making the space of the air outlet device in the axial direction of the first fan 25 more compact. In a specific application example, when the air outlet device is a vertical cabinet, the axial direction of the first fan 25 is the height direction of the vertical cabinet. Therefore, by sleeve-mounting the first housing 12 radially outwardly of the first fan 25, space in the height direction of the vertical cabinet can be saved, which helps to reduce the height of the vertical cabinet.

[0067] In some embodiments, as Figure 3 As shown, the first housing 12 may be provided with a first liquid receiving trough 121, and the first filter 8 is located above the bottom of the first liquid receiving trough 121. The cleaning liquid on the first filter 8 can flow into the first liquid receiving trough 121 under the action of its own gravity.

[0068] In the above example, the first liquid receiving tank 121 is designed to collect the dirty cleaning liquid after cleaning the first filter screen 8, which is conducive to uniformly discharging the dirty cleaning liquid.

[0069] In some embodiments, as Figure 3As shown, the aforementioned air outlet device has a water receiving tray, and the bottom of the aforementioned first liquid receiving tank 121 can be provided with a first liquid drainage hole 122, and the first liquid drainage hole 122 is located above the water receiving tray. The cleaning liquid in the first liquid receiving tank 121 can flow to the water receiving tray through the first liquid drainage hole 122 under the action of its own gravity.

[0070] In the above example, the air outlet device can be an air conditioner, and the above water receiving tray can be the evaporator water receiving tray of the air conditioner. By draining the dirty cleaning liquid in the first liquid receiving tank 121 into the evaporator water receiving tray, it is convenient to discharge the dirty cleaning liquid in the first liquid receiving tank 121 and the condensed water in the evaporator water receiving tray together from the drain pipe on the evaporator water receiving tray to the outside.

[0071] In some embodiments, as Figure 3-5 As shown, the first filter 8 can be cylindrical. The first nozzles 9 can be two or more in number and disposed around the first filter 8. Each first nozzle 9 is connected via a first connecting pipe 10. The pump body 13 pumps the cleaning liquid in the first tank 12 into the first connecting pipe 10, causing the cleaning liquid to flow along the first connecting pipe 10 to each first nozzle 9.

[0072] In the above example, since each first nozzle 9 is connected to the pump body 13 through the same connecting pipe (ie, the first connecting pipe 10), it has the advantages of simplifying the structure and reducing the cost.

[0073] In some embodiments, as Figure 3-5 As shown, the aforementioned air outlet device may further include a first bracket 11, on which the aforementioned first nozzle 9 is disposed. The first bracket 11 is used to provide support for the first nozzle 9. Specifically, when the first filter 8 is cylindrical, the first bracket 11 may also be cylindrical, and the first bracket 11 is disposed outside the first filter 8. When there are two or more first nozzles 9, each first nozzle 9 is disposed on the first bracket 11 and surrounds the first filter 8.

[0074] In the above example, the provision of the first bracket 11 facilitates the installation and fixation of the first nozzle 9 .

[0075] In some embodiments, the aforementioned air outlet device may further include a first valve switch for controlling the opening and closing of the first nozzle 9. The first valve switch may be disposed inside the first nozzle 9 to facilitate controlling the opening and closing of the first nozzle 9. The first valve switch may be a solenoid valve, etc.

[0076] In some embodiments, when the air outlet device includes a second filter 17, the aforementioned liquid spraying mechanism may include a second liquid spraying mechanism to spray the cleaning liquid onto the second filter 17 through the second liquid spraying mechanism. Figure 6-7As shown, the second liquid spraying mechanism can include a second housing 15 and a second nozzle 16. The second housing 15 is used to hold a cleaning liquid, such as water. The second housing 15 is positioned above a second filter 17. The second nozzle 16 is connected to the interior of the second housing 15. The cleaning liquid in the second housing 15 flows to the second nozzle 16 under the action of gravity, causing the second nozzle 16 to spray the cleaning liquid onto the second filter 17.

[0077] In the above example, the second box body 15 cooperates with the second nozzle 16 to realize the function of the second liquid spraying structure spraying the cleaning liquid onto the second filter 17 .

[0078] In some embodiments, as Figure 7 As shown, the aforementioned fan mechanism may include a second fan 20, which may be a centrifugal fan, etc. The fan mechanism can, through the second fan 20, drive air into the second air inlet 6 and out of the first air outlet 1 in a first state. Furthermore, the fan mechanism can, through the second fan 20, drive air into the first air inlet 2 and out of the second air outlet 23 in a second state. The second housing 15 is annular and is disposed radially outside the second fan 20.

[0079] In the above example, by sleeve-mounting the second housing 15 radially outward of the second fan 20, the space radially outward of the second fan 20 can be fully utilized, making the space of the air outlet device in the axial direction of the second fan 20 more compact. In a specific application example, when the air outlet device is a vertical cabinet, the axial direction of the second fan 20 is the height direction of the vertical cabinet. Therefore, by sleeve-mounting the second housing 15 radially outward of the second fan 20, space in the height direction of the vertical cabinet can be saved, which helps to reduce the height of the vertical cabinet.

[0080] In some embodiments, as Figure 7 As shown, a second liquid receiving tank 24 may be provided below the second filter screen 17 , and the cleaning liquid on the second filter screen 17 may flow into the second liquid receiving tank 24 under the action of its own gravity.

[0081] In the above example, the second liquid collecting tank 24 is designed to collect the dirty cleaning liquid after cleaning the second filter screen 17, which is conducive to uniformly discharging the dirty cleaning liquid.

[0082] In some embodiments, the aforementioned air outlet device has a water receiving tray, and a drainage pipe is provided at the bottom of the water receiving tray. Figure 7 As shown, a second drainage hole 241 is provided at the bottom of the second liquid receiving tank 24, and the second drainage hole 241 is connected to the drainage pipe. The cleaning liquid in the second liquid receiving tank 24 can flow to the drainage pipe through the second drainage hole 241 under the action of its own gravity.

[0083] In the above example, the air outlet device can be an air conditioner, and the above-mentioned water collecting pan can be the evaporator water collecting pan of the air conditioner. By discharging the dirty cleaning liquid in the second liquid collecting tank 24 to the drainage pipe of the evaporator water collecting pan, the dirty cleaning liquid in the second liquid collecting tank 24 can be conveniently discharged to the outside through the drainage pipe of the whole machine, that is, the drainage pipe of the evaporator water collecting pan.

[0084] In some embodiments, as Figure 6-7 As shown, the second filter 17 can be cylindrical. The second nozzles 16 can be two or more in number and arranged around the second filter 17. Each second nozzle 16 is connected via a second connecting pipe 19. The cleaning liquid within the second housing 15 flows into the second connecting pipe 19 under its own gravity and then flows along the second connecting pipe 19 to each second nozzle 16.

[0085] In the above example, since each second nozzle 16 is connected to the second box 15 through the same connecting pipe (ie, the second connecting pipe 19), it has the advantages of simplifying the structure and reducing the cost.

[0086] In some embodiments, as Figure 6-7 As shown, the aforementioned air outlet device may further include a second bracket 18, on which the aforementioned second nozzle 16 is mounted. The second bracket 18 is used to provide support for the second nozzle 16. Specifically, when the second filter 17 is cylindrical, the second bracket 18 may also be cylindrical, and the second bracket 18 is positioned outside the second filter 17. When there are two or more second nozzles 16, each second nozzle 16 is mounted on the second bracket 18 and surrounds the second filter 17.

[0087] In some embodiments, the aforementioned air outlet device may further include a second valve switch for controlling the opening and closing of the second nozzle 16. The second valve switch may be disposed inside the second nozzle 16 to facilitate controlling the opening and closing of the second nozzle 16. The second valve switch may be a solenoid valve, etc.

[0088] In some embodiments, the aforementioned fan mechanism can rotate forward and reverse. Specifically, when the fan mechanism includes the aforementioned first fan 25, the first fan 25 can rotate forward and reverse. Similarly, when the fan mechanism includes the aforementioned second fan 20, the second fan 20 can rotate forward and reverse.

[0089] In one example, when the air outlet device includes a first filter 8, the fan mechanism is configured to rotate forward in the second state, causing air to pass through the first filter 8 in a first direction a. The air outlet device further includes a third state. In the third state, the first air outlet 1 is closed, and the fan mechanism rotates in reverse to drive air through the first filter 8 in a second direction a. The first direction a is opposite to the second direction a. In another example, when the air outlet device includes a second filter 17, the fan mechanism is configured to rotate forward in the first state, causing air to pass through the second filter 17 in a first direction b. The air outlet device further includes a fourth state. In the fourth state, the second air outlet 23 is closed, and the fan mechanism rotates in reverse to drive air through the second filter 17 in a second direction b. The first direction b is opposite to the second direction b.

[0090] In the above example, when the fan mechanism rotates forward, the air intake function of the first air inlet 2 and the second air inlet 6 can be realized. When the fan mechanism rotates reversely, the wind can pass through the first filter 8 or the second filter 17 in the opposite direction, so that the fluffy debris on the filter that is difficult to wash off with cleaning liquid can be removed.

[0091] It should be noted here that: when the fan mechanism has both the first fan 25 and the second fan 20, in the aforementioned first and second states, the first fan 25 and the second fan 20 both rotate forward; in the third and fourth states, the first fan 25 and the second fan 20 both rotate reverse.

[0092] In some embodiments, when the air outlet device includes the first filter 8, the air outlet device includes a first air volume sensor, and the first air volume sensor is used to detect the air volume at the second air outlet 23 in the second state.

[0093] In the above example, the degree of dirtiness and blockage of the first filter 8 can be detected by the first air volume sensor. When the fan mechanism operates at the same speed, the smaller the air volume of the second air outlet 23 in the second state, the more serious the dirtiness and blockage of the first filter 8. This can be used to determine whether to start the spray mechanism to spray liquid to clean the first filter 8.

[0094] In some embodiments, the aforementioned air outlet device may further include a first display device, and the first display device is used to feedback the detection result of the first air volume sensor. In a specific application example, the first display device may include a first display light, the number of the first display lights is more than two, and the colors of each first display light after lighting up are different. The first display device feeds back the detection result of the first air volume sensor by lighting up the corresponding first display light or turning off each first display light. For example, the first display light may include a yellow display light and a red display light. When the air volume at the second air outlet is high, it means that the first filter 8 is slightly dirty and blocked. At this time, all the first display lights are turned off, no prompt action is taken, and the air outlet device continues to operate according to the set mode. When the air volume at the second air outlet is medium, it means that the first filter 8 is moderately dirty and blocked. At this time, the yellow display light is on, and the user determines whether to start cleaning. If so, the cleaning mode program is executed, otherwise it continues to operate according to the set mode. When the air volume at the second air outlet is low, it indicates that the first filter 8 is severely clogged. The red indicator light illuminates, and the user decides whether to start cleaning. If so, the cleaning mode procedure is executed; otherwise, the system continues to operate according to the set mode. The first air volume sensor feeds back the detection result to the user via the first display device, and the user decides whether to start the cleaning procedure. The first display device can serve as a reminder, thereby preventing the user from neglecting to clean the filter for a long time due to negligence, which may affect the air quality and human health.

[0095] In a specific application example, the aforementioned air outlet device may include a first controller, which is used to control all first display lights of the first display device to turn off when the air volume detected by the first air volume sensor is between 80% and 100% of the first preset air volume. The first controller is also used to control the first display light that displays a first color, such as yellow, to turn on when the air volume detected by the first air volume sensor is between 50% and 80% of the first preset air volume. The first controller is also used to control the first display light that displays a second color, such as red, to turn on when the air volume detected by the first air volume sensor is less than 50% of the first preset air volume.

[0096] The first preset air volume is the air volume detected when the air outlet device uses the first filter for the first time, and the first filter is in an uncontaminated state at this time. The first controller may be a processor or a PLC logic controller.

[0097] In some embodiments, when the air outlet device includes the second filter 17, the air outlet device includes a second air volume sensor, and the second air volume sensor is used to detect the air volume at the first air outlet 1 in the first state.

[0098] In the above example, the degree of dirtiness and blockage of the second filter 17 can be detected by the second air volume sensor. When the fan mechanism is operating at the same speed, the smaller the air volume of the first air outlet 1 in the first state, the more serious the dirtiness and blockage of the second filter 17. This can be used to determine whether to start the spray mechanism to spray liquid to clean the second filter 17.

[0099] In some embodiments, the aforementioned air outlet device may further include a second display device, which is used to feedback the detection results of the second air volume sensor. In a specific application example, the second display device may include a second display light, the number of the second display lights being two or more, and the colors of each second display light being different after being lit. The second display device feedbacks the detection results of the second air volume sensor by lighting up the corresponding second display light or turning off each second display light. For example, the second display light may include a yellow display light and a red display light. When the air volume at the first air outlet 1 is high, it indicates that the second filter 17 is slightly dirty and clogged. At this time, all the second display lights are turned off, no prompt action is taken, and the air outlet device continues to operate according to the set mode. When the air volume at the first air outlet 1 is medium, it indicates that the second filter 17 is moderately dirty and clogged. At this time, the yellow display light is on, and the user decides whether to start cleaning. If so, the cleaning mode program is executed; otherwise, it continues to operate according to the set mode. When the air volume at the first air outlet 1 is low, it indicates that the second filter 17 is severely clogged. At this time, the red indicator light comes on, and the user decides whether to start cleaning. If yes, the cleaning mode program is executed; otherwise, the system continues to operate according to the set mode. The second air volume sensor feeds back the detection result to the user through the second display device, and the user decides whether to start the cleaning program. The second display device can serve as a reminder, thereby preventing the user from neglecting to clean the filter for a long time due to negligence, which may affect the air quality and human health.

[0100] In a specific application example, the aforementioned air outlet device may include a second controller, which is used to control all second display lights of the second display device to turn off when the air volume detected by the second air volume sensor is between 80% and 100% of the second preset air volume. The second controller is also used to control the second display light that displays a first color, such as yellow, to turn on when the air volume detected by the second air volume sensor is between 50% and 80% of the second preset air volume. The second controller is also used to control the second display light that displays a second color, such as red, to turn on when the air volume detected by the second air volume sensor is less than 50% of the second preset air volume.

[0101] The second preset air volume is the air volume detected when the air outlet device uses the second filter for the first time, and the second filter is in an uncontaminated state at this time. The second controller may be a processor or a PLC logic controller.

[0102] In some embodiments, when the air outlet device includes both a first controller and a second controller, the first controller and the second controller may be the same controller.

[0103] In some embodiments, when the air outlet device includes both a first display device and a second display device, the first display device and the second display device may be the same display device, so as to reduce the use of display devices and save costs.

[0104] In some embodiments, the aforementioned air outlet device can be operated in a heating mode, so that the first air outlet 1 and / or the second air outlet 23 can discharge hot air.

[0105] After the first filter 8 and the second filter 17 are cleaned by spraying liquid, the cleaning liquid attached to them may cause mold or bacteria, etc., which may affect the air volume and air quality of the air supply, and affect human respiratory health. In the above example, since the air outlet device can operate in a heating mode, after cleaning, the air outlet device can be turned on to heat and blow air to dry the filter and component surfaces, avoiding hidden dangers such as mold after cleaning. This achieves comprehensive cleaning of the filter, improves the air quality of the air supply, and is more conducive to the user's respiratory health.
