DETAILED DESCRIPTION

[0065] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0066] Unless otherwise specified, directional words such as "upper, lower, left, right" are defined according to the directions indicated in the corresponding drawings, while "inner" and "outer" refer to the inner and outer contours of the corresponding components themselves. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another, and do not have order and importance.

[0067] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0068] like Figures 1 to 6As shown, the present disclosure provides an exemplary air conditioning device. For the purpose of description, a mobile air conditioner is taken as an example for detailed description. It should be understood that air conditioning devices with similar structures and requirements can all apply the solution provided by the present disclosure to solve technical problems, and are not limited to mobile air conditioners. Mobile air conditioners have more layout flexibility than ordinary hanging air conditioners, and can be moved to an appropriate spatial position as needed. This convenient movement can be achieved by setting rollers at the bottom. Mobile air conditioners are usually designed as an integrated internal and external unit. Specifically, the evaporator 4 and the condenser 3, which are the core components of the air conditioner, are integrated in a shell and are both located indoors. Taking the refrigeration condition as an example, the higher temperature air introduced from the environment exchanges heat with the lower temperature evaporator 4 and is discharged to the room, thereby achieving the purpose of lowering the indoor temperature. Under certain conditions, for example, the humidity in the air is high, and condensed water is easily precipitated in the outer shell of the evaporator 4. However, due to the characteristics of the integrated design of the mobile air conditioner, this part of the condensed water is usually not directly discharged to the outside, but a water tank 2 for storing condensed water is set inside the mobile air conditioner. As the amount of condensed water continues to increase, if the condensed water in the water tank 2 is not handled in time, water leakage problems are likely to occur.

[0069] To solve the above-mentioned problems, the air conditioning device provided by the present disclosure is further provided with a guide plate 11, a first monitoring device 41 and a controller 5. The guide plate 11 can be driven to rotate between a first position and a second position. Figure 1 The guide plate 11 is shown in the first position, as shown by the arrow, the guide plate 11 guides the condensed water separated from the outer shell of the evaporator 4 into the water tank 2; Figure 2 It is shown that the guide plate 11 is in the second position. As shown by the arrow, the guide plate 11 guides the condensed water to the condenser 3, thereby cooling the condenser 3. For example, under the refrigeration condition, the external environment temperature is higher, and the temperature of the condenser 3 is also higher, and the excessive temperature will affect the refrigeration efficiency of the condenser 3. Therefore, guiding the condensed water with a lower temperature to the condenser 3 has the effect of cooling the condenser 3, which is beneficial to improving the refrigeration efficiency of the condenser 3. At the same time, after the condensed water with a lower temperature contacts the condenser 3 with a higher temperature, the condensed water can be vaporized, thereby delaying the time for the water tank 2 to be filled with water.

[0070] The first monitoring device 41 is used to monitor the temperature of the evaporator 4. The controller 5 is connected to the first monitoring device 41 and the guide plate 11 respectively. The controller 5 is used to control the guide plate 11 to rotate between the first position and the second position according to the temperature information of the evaporator 4 obtained. The temperature information here is the temperature value. When the temperature of the evaporator 4 is relatively high, for example, greater than or equal to the preset value, the condensed water generated is relatively small. The guide plate 11 is controlled to the second position to reduce the condensed water flowing to the water tank 2, thereby ensuring that there is enough condensed water flowing to the condenser 3; when the temperature of the evaporator 4 is relatively low, for example, less than the preset value, a large amount of condensed water is generated. The guide plate 11 is controlled to the first position to increase the condensed water flowing to the water tank 2.

[0071] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the air conditioning device provided by the present disclosure is provided with a guide plate 11, and the guide plate 11 can rotate between the first position and the second position under the control of the controller 5 according to the temperature of the evaporator 4 monitored by the first monitoring device 41, so as to guide the condensed water precipitated from the outer shell of the evaporator 4 to the water tank 2 and the condenser 3 respectively. For example, when the temperature of the evaporator 4 is high, the condensed water generated is relatively small, and the guide plate 11 is controlled to the second position to reduce the condensed water flowing to the water tank 2, thereby ensuring that there is enough condensed water flowing to the condenser 3; when the temperature of the evaporator 4 is low, a large amount of condensed water is generated, and the guide plate 11 is controlled to the first position to increase the condensed water flowing to the water tank 2. That is, the guide plate 11 rotates between the first position and the second position according to the monitored temperature of the evaporator, and can distribute the condensed water between the water tank 2 and the condenser 3 in a more targeted manner, so that the condensed water can be fully utilized to cool the condenser 3, and the high-temperature condenser 3 can be used to vaporize the condensed water, thereby delaying the filling time of the water tank 2 and avoiding the problem of leakage due to excessive water accumulation.

[0072] In addition to the first position and the second position, the guide plate 11 also has a plurality of intermediate positions between the first position and the second position. Specifically, in the first position, the guide plate 11 guides all the generated condensed water to the water tank 2, in the second position, the guide plate 11 guides all the generated condensed water to the condenser 3, and in the intermediate position, the guide plate 11 can divide the condensed water into the water tank 2 and the condenser 3 in proportion. The distribution ratio of the condensed water can be achieved by adjusting the rotation angle of the guide plate 11 relative to the horizontal position. Optionally, the ratio of the condensed water diverted to the water tank 2 and the condenser 3 can be determined according to the following: η 水箱 =ξθ+0.5;η 冷凝器 =1-η 水箱, where ξ is an angle coefficient in the range of -0.005 to +0.005; θ is the angle of the guide plate relative to the horizontal plane. When θ is positive, more condensed water flows to the water tank 2. For example, for every 5° increase in θ, the condensed water flowing to the water tank 2 increases by 10%, and correspondingly, the condensed water flowing to the condenser 3 decreases by 10%.

[0073] Taking the refrigeration condition as an example, when the temperature of the evaporator 4 is high, for example, greater than or equal to the preset value, the condensed water generated is relatively small. At this time, the angle θ of the guide plate 11 relative to the horizontal plane can be adjusted to make more condensed water flow to the condenser 3, giving priority to providing cooling for the condenser 3, and at the same time, this part of the condensed water can be vaporized, thereby reducing the amount of condensed water, delaying the filling time of the water tank, and avoiding the problem of leakage due to excessive water accumulation; and as the running time of the air conditioner increases, the temperature of the evaporator 4 gradually decreases, and more condensed water is generated. At this time, the angle θ of the guide plate 11 relative to the horizontal plane position can be adjusted to gradually reduce the condensed water flowing to the condenser 3.

[0074] The air conditioning device may also be provided with a second monitoring device 31 for monitoring the temperature of the condenser 3, and the second monitoring device 31 is connected to the controller 5. When the temperature of the condenser 3 is detected to be high, it indicates that the refrigeration efficiency of the condenser 3 is not in the best state, and the refrigeration effect is poor. At this time, the angle θ of the guide plate 11 relative to the horizontal plane can be adjusted to make more condensed water flow to the condenser 3 to cool the condenser 3, and at the same time, this part of the condensed water can be vaporized, thereby reducing the amount of condensed water, delaying the time for the water tank to be full of water, and avoiding the problem of leakage due to excessive water accumulation.

[0075] It should be noted that the first monitoring device 41 and the second monitoring device 31 can work simultaneously, so that the controller 5 can make a comprehensive judgment based on the monitoring results of the two monitoring devices to improve the accuracy of control. At the same time, even if one of the monitoring devices is damaged, it will not affect the control of the guide plate 11. Of course, the first monitoring device 41 and the second monitoring device 31 can also work independently in time-sharing.

[0076] Furthermore, the air conditioning device may also be provided with a third monitoring device 32 for monitoring the ambient temperature and a fourth monitoring device 33 for monitoring the exhaust temperature of the compressor, and the third monitoring device 32 and the fourth monitoring device 33 are respectively connected to the controller 5. The exhaust temperature is usually proportional to the temperature of the condenser 3, and the increase of the ambient temperature will lead to the increase of the exhaust temperature and the temperature of the condenser 3, that is, by monitoring the exhaust temperature and the ambient temperature, the temperature of the condenser 3 can be indirectly monitored, which can actually be regarded as redundant monitoring of the temperature of the condenser 3, thereby providing more accurate temperature information, that is, a comprehensive judgment based on the monitoring results of the third monitoring device 32 and the fourth monitoring device 33 is conducive to improving the accuracy of control, or setting up multiple monitoring devices can also avoid the failure of a monitoring device and affect the monitoring of temperature.

[0077] The change in the angle Δθ of the guide plate 11 relative to the horizontal plane can be determined as follows: -Δθ=aΔT 蒸 +bΔT 冷 +cΔT 排 +dΔT 环 , where ΔT 蒸 is the change in the current evaporator temperature relative to the evaporator temperature in the stable operation phase; ΔT 冷 is the change in current condenser temperature relative to the condenser temperature in the stable operation phase; ΔT 排 ΔT is the change in the current exhaust temperature relative to the exhaust temperature in the stable operation stage; 环 is the change in the current ambient temperature relative to the ambient temperature in the stable operation stage; the temperature in the stable operation stage is the temperature whose value changes within ±0.5℃ within the predetermined time; a, b, c, d are the coefficients of change in the range of 0-10. For example, when ΔT 蒸 , ΔT 冷 , ΔT 排 , ΔT 环 When both increase, θ decreases, and more condensed water flows to condenser 3. On the contrary, when ΔT 蒸 , ΔT 冷 , ΔT 排 , ΔT 环 When both decrease, θ increases, the condenser 3 needs more condensed water for heat exchange, and more condensed water flows to the water tank 2.

[0078] The present disclosure does not limit the driving method of the guide plate 11. In some embodiments, Figures 4 to 6As shown, the driving mechanism is a rotary motor 12, and the output shaft of the rotary motor 12 is connected to the guide plate 11, that is, the rotary motor 12 directly drives the guide plate 11, so that the guide plate 11 rotates between the first position and the second position and any position therebetween. The rotary motor 12 can be a servo motor, so that the rotation angle of the guide plate 11 can be more accurately controlled, so as to more accurately distribute the amount of condensed water diverted to the water tank 2 and the condenser 3. In addition, in other embodiments, a driving method of a linear motor and mutually meshing gears and racks can also be adopted, wherein the guide plate 11 is fixedly mounted on the gear so that it can change position as the gear rotates, and the output shaft of the linear motor is connected to the rack, that is, the linear motion of the linear motor is converted into the rotation of the guide plate 11 through the gear and the rack. Other forms of driving mechanisms, as long as they can realize the rotation of the guide plate 1 between the first position and the second position, can be applied to the present disclosure, and are not limited here.

[0079] like Figure 1 and Figure 2 As shown, the air conditioning device generally adopts a cabinet structure, including an integral shell 6. Specifically, the air conditioning device includes a first accommodating space 61 and a second accommodating space 62 arranged up and down for accommodating, wherein the evaporator 4 is arranged in the first accommodating space 61, and the condenser 3 and the water tank 2 are arranged in the second accommodating space 62. A partition 63 is arranged between the first accommodating space 61 and the second accommodating space 62, and the partition 63 is provided with a drain port 631 for condensed water to be discharged. The guide plate 11 is arranged in the second accommodating space 62 and its position corresponds to the drain port 631. On the one hand, the partition 63 has the function of supporting the evaporator 4 and improving the strength of the support. On the other hand, the drain port 631 for condensed water to be discharged arranged on the partition 63 has the function of converging, that is, guiding the condensed water to be discharged from the drain port 631 in a concentrated manner, so as to facilitate being received by the guide plate 11.

[0080] In order to facilitate the diversion, Figures 4 to 6 As shown, the guide plate 11 is constructed as an arc-shaped plate protruding toward the flow direction of the condensed water, or the guide plate 1 protrudes toward the direction of the drain port 631. This arc-shaped guide plate 11 can make the condensed water flow to the water tank 2 or the condenser 3 more smoothly, and the arc-shaped structure is also conducive to diversion, that is, it is more conducive to proportionally diverting the condensed water to the water tank 2 and the condenser 3 at the middle position. Guide plates 11 of other shapes, for example, triangular guide plates 1, can also be used in the present disclosure to achieve the purpose of diversion and diversion. Figure 6 As shown, the guide plate 11 may include a plate body 111 extending in the guide direction and water retaining strips 112 arranged on both sides of the plate body 111 in the guide direction. The presence of the water retaining strips 112 can prevent the condensed water on the guide plate 11 from sliding down from the side of the plate body 111 without being able to be guided to the water tank 2 or the condenser 3.

[0081] The air conditioning device provided by the present disclosure may also include a limiter 7 for limiting the rotation angle of the guide plate 11. By setting the limiter 7, the rotation angle of the guide plate 11 can be limited, and the guide plate 11 can be limited to the first position and the second position. It should be noted that the limit here means that the guide plate 11 cannot continue to rotate after being driven to a predetermined position. In this way, even if the driving mechanism has a deviation in the control angle or there is rotational inertia, the guide plate 11 can still be accurately stopped at the first position or the second position.

[0082] like Figure 5 and Figure 6 As shown, the air conditioning device of the present disclosure may further include a water storage tank 8, which includes a first water storage chamber 81 and a second water storage chamber 82 separated from each other. An additional partition plate may be provided between the first water storage chamber 81 and the second water storage chamber 82, or as shown in FIG. Figure 6 The limiting member 7 shown extends into the water tank 8 to form a partition. The first water storage chamber 81 is provided with a first overflow port 811, and the position of the first overflow port 811 corresponds to the water inlet 21 of the water tank 2. Optionally, the first overflow port 811 can be inserted into the water inlet 21 through the lead-out water pipe; the second water storage chamber 82 is provided with a second overflow port 821, and the position of the second overflow port 821 corresponds to the condenser 3. This method of setting up the water tank 8 can provide a larger opening and accommodating space, so that it is easier to receive the diverted condensed water. At the same time, the separated first water storage chamber 81 and the second water storage chamber 82 can prevent the water in the two chambers from being connected and merging with each other, which is particularly suitable for working conditions with diversion requirements.

[0083] Furthermore, if Figures 4 to 6 As shown, a first water receiving pan 9 may be further provided between the water storage tank 8 and the condenser 3. The first water receiving pan 9 at least partially covers the condenser 3, and the first water receiving pan 9 is provided with a plurality of third overflow ports 91 at intervals, so that the first water receiving pan 9 has a sufficiently large overflow area, so that the condensed water can be evenly distributed on the condenser 3, and the condenser 3 is fully cooled, that is, the first water receiving pan 9 here plays the role of storing the condensed water on the one hand, and plays the role of a homogenizer on the other hand.

[0084] like Figures 1 to 3As shown, the air conditioning device of the present disclosure may further include a second water receiving tray 101 disposed at the bottom of the condenser 3 and a fifth monitoring device 103 and / or a sixth monitoring device 104 respectively connected to the controller 5. The second water receiving tray 101 is used to store condensed water that has been directed to the condenser 3 but has not been vaporized, and is temporarily stored in the second water receiving tray 101 to avoid water leakage. The fifth monitoring device 103 is used to monitor the rising speed of the condensed water in the second water receiving tray 101. The sixth monitoring device 104 is used to monitor the current water level in the second water receiving tray 101. Specifically, when the condensed water in the second water receiving tray 101 rises at a certain speed, for example 0-3L / h, it means that the condensed water in the second water receiving tray 101 rises too fast, and the guide plate 11 is controlled to reduce the amount of water flowing to the condenser 3, so as to avoid the continuous increase of water accumulation in the second water receiving tray 101 and overflow; when the current water volume reaches the preset value, for example, 90% of the full load water volume, the amount of water flowing to the condenser 3 is reduced or all the condensed water is diverted to the water tank 2, so as to avoid the continuous increase of water accumulation in the second water receiving tray 101 and overflow.

[0085] Furthermore, the air conditioning equipment may also include a water pumping device 102, which is used to pump the condensed water in the second water receiving tray 101 onto the condenser 3, so as to vaporize the condensed water stored in the second water receiving tray 101. The water pumping device 102 may be, for example, a water wheel, which sprinkles the condensed water onto the condenser 3 during rotation.

[0086] The present disclosure also provides an exemplary control method for an air conditioning device. The air conditioning device includes a guide plate 11, which can be driven to have a first position and a second position, wherein: in the first position, the guide plate 11 guides condensed water precipitated from the outer shell of the evaporator 4 to the water tank 2; in the second position, the guide plate 11 guides the condensed water to the condenser 3. In addition, the air conditioning device can also be applied to the air conditioning device in any of the aforementioned embodiments.

[0087] Specifically, the control method includes: acquiring a temperature value of the evaporator; and controlling the guide plate to rotate between a first position and a second position in response to the acquired temperature value of the evaporator.

[0088] Optionally, in response to the acquired temperature value of the evaporator, the step of controlling the guide plate to rotate between the first position and the second position includes: when the temperature value of the evaporator is greater than or equal to a first preset value, controlling the guide plate to rotate toward the second position; when the temperature value of the evaporator is less than the first preset value, controlling the guide plate to rotate toward the first position.

[0089] Taking the refrigeration condition as an example, when the temperature of the evaporator 4 is relatively high, for example, greater than or equal to the first preset value, the condensed water generated is relatively small. At this time, the angle θ of the guide plate 11 relative to the horizontal plane can be adjusted to make more condensed water flow to the condenser 3, giving priority to providing cooling for the condenser 3, and at the same time, this part of the condensed water can be vaporized, thereby reducing the amount of condensed water, delaying the filling time of the water tank, and avoiding the problem of leakage due to excessive water accumulation; and as the running time of the air conditioner increases, the temperature of the evaporator 4 gradually decreases, and more condensed water is generated, for example, less than the first preset value. At this time, the angle θ of the guide plate 11 relative to the horizontal plane can be adjusted to gradually reduce the condensed water flowing to the condenser 3.

[0090] In response to the acquired temperature value of the evaporator, the guide plate is controlled to rotate to a plurality of intermediate positions between the first position and the second position, and at the intermediate position, the guide plate divides the condensed water into the water tank and the condenser in proportion, wherein the proportion of the condensed water divided into the water tank and the condenser is determined according to the following: n 水箱 =ξθ+0.5;η 冷凝器 =1-η 水箱 . Wherein, ξ is an angle coefficient ranging from -0.005 to +0.005; θ is the angle of the guide plate relative to the horizontal plane.

[0091] In some embodiments, the steps of the control method also include: obtaining the temperature value of the condenser; when the temperature value of the evaporator is greater than or equal to a first preset value and the temperature value of the condenser is greater than or equal to a second preset value, controlling the guide plate to rotate toward the second position; when the temperature value of the evaporator is less than the first preset value and the temperature value of the condenser is less than the second preset value, controlling the guide plate to rotate toward the first position.

[0092] When the temperature value of the evaporator is greater than or equal to the first preset value, the condensed water generated at this time is relatively small, and the temperature value of the condenser is greater than or equal to the second preset value, indicating that the high temperature of the condenser may affect the refrigeration efficiency. At this time, the angle θ of the guide plate 11 relative to the horizontal plane position can be adjusted to make more condensed water flow to the condenser 3, and the condenser 3 can be cooled first. At the same time, this part of the condensed water can be vaporized, thereby reducing the amount of condensed water, delaying the water tank from being full of water, and avoiding the problem of water leakage due to excessive water accumulation. On the contrary, the temperature value of the evaporator is less than the first preset value and the temperature value of the condenser is less than the second preset value, indicating that the evaporator 4 generates more condensed water, and the condenser does not need more condensed water for cooling. At this time, the condensed water flowing to the condenser 3 can be gradually reduced by adjusting the angle θ of the guide plate 11 relative to the horizontal plane position.

[0093] Further, the control method also includes the following steps: obtaining the ambient temperature value and the exhaust temperature value of the compressor; when the temperature value of the evaporator is greater than or equal to the first preset value, the temperature of the condenser is greater than or equal to the second preset value, the ambient temperature value is greater than or equal to the third preset value, and the exhaust temperature is greater than or equal to the fourth preset value, controlling the guide plate to rotate toward the second position; when the temperature value of the evaporator is less than the first preset value, the temperature of the condenser is less than the second preset value, the ambient temperature value is less than the third preset value, and the exhaust temperature is less than the fourth preset value, controlling the guide plate to rotate toward the first position. The exhaust temperature is usually proportional to the temperature of the condenser 3, and an increase in the ambient temperature will cause an increase in the exhaust temperature and the temperature of the condenser 3.

[0094] The change in the angle Δθ of the guide plate relative to the horizontal plane is determined as follows: -Δθ=aΔT 蒸 +bΔT 冷 +cΔT 排 +dΔT 环 . Among them, ΔT 蒸 is the change in the current evaporator temperature relative to the evaporator temperature in the stable operation phase; ΔT 冷 is the change in current condenser temperature relative to the condenser temperature in the stable operation phase; ΔT 排 ΔT is the change in the current exhaust temperature relative to the exhaust temperature in the stable operation stage; 环 It is the change of the current ambient temperature relative to the ambient temperature in the stable operation stage; the temperature in the stable operation stage is the temperature whose value changes within ±0.5℃ within the predetermined time; a, b, c, d are the coefficients of change in the range of 0-10.

[0095] The present disclosure also exemplarily provides a control method for an air conditioning device, the air conditioning device includes a guide plate 11 and a second water receiving tray 101 arranged at the bottom of the condenser 3, the guide plate 11 can be driven to have a first position and a second position, wherein: in the first position, the guide plate 11 guides the condensed water separated from the outer shell of the evaporator 4 to the water tank 2; in the second position, the guide plate 11 guides the condensed water to the condenser 3. In addition, the air conditioning device can also be applied to the air conditioning device in any of the aforementioned embodiments.

[0096] Specifically, the control method includes: obtaining the rising speed value of the condensed water in the second water receiving tray; when the rising speed value is greater than or equal to the fifth preset value, controlling the guide plate to rotate toward the first position; when the rising speed value is less than the fifth preset value, controlling the guide plate to rotate toward the second position, that is, when the condensed water in the second water receiving tray 101 rises at a certain speed, for example 0-3L / h, it means that the rising speed of the condensed water in the second water receiving tray 101 is too fast, and the guide plate 11 is controlled to reduce the amount of water flowing to the condenser 3, so as to avoid the continuous increase of water accumulation in the second water receiving tray 101 and overflow. And / or take the current water level value of the condensed water in the second water receiving tray; when the current water level value is greater than or equal to the sixth preset value, control the guide plate to rotate toward the first position; when the current water level value is less than the sixth preset value, control the guide plate to rotate toward the second position, that is, when the current water volume reaches the preset value, for example, when it reaches 90% of the full load water volume, reduce the amount of water flowing to the condenser 3 or divert all the condensed water to the water tank 2 to avoid the continuous increase of water accumulation in the second water receiving tray 101 and overflow.
