Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to an angle air cooler, a control method and a refrigeration device. Background Art

[0002] Among refrigeration equipment, air coolers are widely used in factory workshops, cold storage and other places for ventilation and cooling. It has the advantages of energy saving and environmental protection, fast cooling and low operating cost. Its common structural types include attached Figure 1 As shown, this common structural type of air cooler has a wide application market and good heat exchange effect, but it is relatively high; therefore, when used in certain special cold storages or special occasions with high requirements for air coolers, the use of this common structural type of air cooler will affect its refrigeration effect.

[0003] To solve the above problems, some manufacturers will lower the evaporator height of the air cooler for some special cold storage or special occasions with high requirements for the air cooler. However, the air volume requirements must be taken into consideration at the same time. Under the condition of the vertical height of the evaporator, it is difficult to match the air cooler that meets the air volume requirements. Therefore, in order to ensure the air volume requirements of the refrigeration equipment, as shown in the attached Figure 2 As shown, the air cooler is installed obliquely, and because of its special structure, it is called an angle air cooler.

[0004] When the angle air cooler is running, the surface temperature of its evaporator is lower than the ambient dew point temperature, and the water vapor in the air will condense into water droplets on the surface of the angle air cooler, forming condensation. Due to the special installation position and structural characteristics of the angle air cooler, the water tray can only catch the condensation water on the evaporator and the left and right side panels, but not on the fan installation plate. This may cause water droplets to fall and wet the surrounding goods or equipment.

[0005] Therefore, how to provide an angle air cooler with good anti-condensation effect is an urgent problem to be solved. Summary of the invention

[0006] The present invention provides an angle air cooler, a control method and a refrigeration device, which are used to solve the problem of poor anti-condensation effect of the angle air cooler in the prior art.

[0010] Furthermore, the driving mechanism includes a rack, a driving device and a gear;

[0013] When the first water receiving tray is fully extended relative to the second water receiving tray, the contact surface of the first sealing component is tightly fitted with the contact surface of the second sealing component.

[0014] Furthermore, a third sealing member is provided on the front side wall of the first water receiving tray and on one side along the retraction direction thereof;

[0015] When the first water receiving tray is completely retracted relative to the second water receiving tray, the contact surface of the third sealing member is tightly fitted with the corresponding front side wall of the second water receiving tray.

[0016] Furthermore, a gap is provided between the bottom of the first water receiving tray and the bottom of the second water receiving tray, and a drainage hole is provided at the bottom of the second water receiving tray;

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0060] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0061] Example 1

[0062] When the angle air cooler in the prior art is in operation, when the surface temperature of its evaporator is lower than the ambient dew point temperature, water vapor in the air will condense into water droplets on the surface of the angle air cooler, forming condensation. Due to the special installation position and structural characteristics of the angle air cooler, the water tray can only catch the condensation water on the surface of the evaporator and the left and right side panels, but cannot catch the condensation water on the surface of the fan installation plate, which may cause water droplets to fall and wet the surrounding goods or equipment.

[0063] Therefore, to solve the above problems, refer to the attached Figure 3-4 The present invention proposes an angle air cooler with good anti-condensation effect, including a fan 2 arranged on an angled surface 1 of the angle air cooler, and a retractable water receiving tray structure 3 is horizontally provided at the bottom of the angle air cooler corresponding to the fan 2; and the water receiving tray structure 3 can be extended to the bottom of the fan 2 to receive condensation water dripping from the fan 2, that is, the maximum extension length of the water receiving tray structure 3 is not less than the maximum horizontal extension distance of the angle air cooler along its Y-axis direction.

[0064] It should be noted that the angle air cooler in this embodiment is also provided with a main control unit (not shown, the same as in the whole text), and the main control unit can be electrically connected to the water receiving pan structure 3. In this embodiment, a fan mounting plate is laid on the angled surface 1, and a fan 2 is mounted on the fan mounting plate, and an evaporator 7 is vertically mounted on the side of the housing of the angle air cooler away from the angled surface 1.

[0065] The Y-axis direction in this embodiment refers to the expansion and contraction direction of the water receiving tray structure 3. The width of the water receiving tray structure 3 along the X-axis direction is greater than or equal to the width of the angle air cooler along the X-axis direction, so as to prevent some condensation water of the angle air cooler from not being caught by the water receiving tray structure 3.

[0066] Therefore, when the angle air cooler is in operation, when the condensation condition is met (the condensation condition is that the temperature of the angled surface 1 is less than or equal to the dew point temperature of the environment), the water vapor in the air will condense into water droplets on the surface of the angle air cooler to form condensation. At this time, the main control unit will control the water receiving tray structure 3 to extend until it is fully extended (that is, indicating that the water receiving tray structure 3 is at the maximum extension length at this time), thereby ensuring that the water receiving tray structure 3 can completely receive the condensation water generated by the angle air cooler (that is, the condensation water generated by the evaporator 7, the surface of the two side plates of the angle air cooler along the X-axis direction and the surface of the angled surface 1 all drip into the water receiving tray structure 3), thereby ensuring that the condensation water generated by the angle air cooler will not wet the surrounding goods or equipment, thereby improving the anti-condensation effect of the angle air cooler.

[0067] That is, when the water receiving tray structure 3 is in a fully retracted state, the water receiving tray structure 3 can receive the condensed water on the surfaces of the two side plates of the evaporator 7 and the angle air cooler along the X-axis direction; and when the water receiving tray structure 3 is in a fully extended state, the water receiving tray structure 3 can receive the condensed water on the surfaces of the two side plates of the evaporator 7 and the angle air cooler along the X-axis direction, and can also simultaneously receive the condensed water generated on the surface of the angled surface 1.

[0068] It should be noted that, under the condition that the height of the evaporator 7 is constant, if the size of the selected fan 2 is larger, the surface area of ​​the bevel surface 1 is larger and the inclination angle of the bevel surface 1 is smaller; if the size of the selected fan 2 is smaller, the surface area of ​​the bevel surface 1 is smaller and the inclination angle of the bevel surface 1 is larger.

[0069] In order to ensure that the water tray structure 3 can better receive the condensation water generated by the angle air cooler, refer to the attached Figure 5-6 , this implementation proposes a double-layer water tray structure 3:

[0070] The water receiving tray structure 3 includes a first water receiving tray 31 and a second water receiving tray 32;

[0071] The first water receiving tray 31 is located above the second water receiving tray 32 and is slidably connected thereto; and a driving mechanism 33 is provided on both sides of the sliding connection between the first water receiving tray 31 and the second water receiving tray 32, and the driving mechanism 33 is used to control the first water receiving tray 31 to extend or retract relative to the second water receiving tray 32.

[0072] It should be noted that the main control unit is electrically connected to the driving mechanism 33. The maximum extension length of the water receiving tray structure 3 is equal to the length L1 of the first water receiving tray 31 along its Y-axis direction plus the length L2 of the second water receiving tray 32 along its Y-axis direction, and the maximum horizontal extension distance of the angle air cooler along its Y-axis direction is L, so L1+L2≥L.

[0073] It should be noted that when the first water receiving tray 31 is fully retracted relative to the second water receiving tray 32 , the first water receiving tray 31 is located inside the second water receiving tray 32 .

[0074] Among them, refer to the attached Figure 7-8 The specific sliding connection structure between the first water receiving tray 31 and the second water receiving tray 32 is as follows:

[0075] First guide rails 313 are horizontally disposed on upper portions of both sides of the first water receiving tray 31 along the X-axis direction, and second guide rails 323 are horizontally disposed on upper portions of both sides of the second water receiving tray 32 along the X-axis direction.

[0076] The rear side walls of the first water receiving tray 31 are provided with first extension plates 314 extending vertically outward along both sides of the X-axis direction and toward the corresponding second guide rail 323. A first support shaft 315 is provided on the top of each first extension plate 314 and on one side facing the corresponding second guide rail 323. The end of each first support shaft 315 is rotatably connected to a first guide wheel 316, and the first guide wheel 316 can match and slide on the corresponding second guide rail 323.

[0077] Similarly, the front side walls of the second water receiving tray 32 have second extension plates 324 extending vertically outward along both sides of the X-axis direction and toward the corresponding first guide rail 313, and a second support shaft 325 is provided on the top of each second extension plate 324 and on one side facing the corresponding first guide rail 313, and the end of each second support shaft 325 is rotatably connected to a second guide wheel 326, and the second guide wheel 326 can match and slide on the corresponding first guide rail 313.

[0078] In this way, the first water receiving tray 31 is slidably connected to the corresponding second guide rail 323 through the first guide wheel 316, and the second water receiving tray 32 is slidably connected to the corresponding first guide rail 313 through the second guide wheel 326, thereby realizing the sliding connection between the first water receiving tray 31 and the second water receiving tray 32.

[0079] In order to ensure that the first water receiving tray 31 can automatically extend or retract relative to the second water receiving tray 32, refer to the attached Figure 5 and 7 , this embodiment proposes a driving mechanism 33:

[0080] The driving mechanism 33 includes a rack 331, a driving device 332 and a gear 333;

[0081] The second water receiving tray 32 is provided with horizontal racks 331 on the upper parts of both sides along the X-axis direction thereof, and the first water receiving tray 31 is provided with a driving device 332 corresponding to the racks 331, and the output end of the driving device 332 is connected to a gear 333, and the gear 333 is located above the corresponding rack 331 and meshes with it.

[0082] It should be noted that the driving device 332 of this embodiment is preferably a motor, and the driving device 332 is electrically connected to the main control unit.

[0083] Among them, the rack 331 is located below the corresponding second guide rail 323; and a driving device 332 is provided on the side of the first extension plate 314 toward the retraction direction of the first water receiving tray 31, and the output end of the driving device 332 is arranged at the upper part of the side of the driving device 332 toward the corresponding second guide rail 323.

[0084] In this way, when the driving device 332 controls the gear 333 to rotate clockwise, the gear 333 will drive the first water receiving tray 31 to extend outward along the corresponding rack 331; similarly, when the driving device 332 controls the gear 333 to rotate counterclockwise, the gear 333 will drive the first water receiving tray 31 to retract inward along the corresponding rack 331.

[0085] In order to ensure that the first water receiving tray 31 can slide relatively to the second water receiving tray 32 more easily and labor-savingly, when the gear 333 is meshed and rotated with the corresponding rack 331 , the guide wheel will also slide on the corresponding guide rail at the same time.

[0086] In order to ensure that the condensed water in the first water receiving tray 31 and / or the second water receiving tray 32 does not overflow from the gap between the rear side wall of the first water receiving tray 31 and the front side wall of the second water receiving tray 32 when the first water receiving tray 31 is fully extended relative to the second water receiving tray 32, refer to the attached Figure 5 and 9 A first sealing member 311 is provided on the rear side wall of the first water receiving tray 31 and along one side of its extending direction, and a second sealing member 321 is provided on the front side wall of the second water receiving tray 32 and along one side of the first water receiving tray 31 and along the retracting direction;

[0087] When the first water receiving tray 31 is fully extended relative to the second water receiving tray 32 , the contact surface of the first sealing member 311 can be closely fitted with the contact surface of the second sealing member 321 .

[0088] It should be noted that the first extension plate 314, on one side of the extension direction of the first water receiving tray 31, plus the portion of the bottom of the rear side wall of the first water receiving tray 31 extending downward and on one side of the extension direction of the first water receiving tray 31, are covered with the first sealing member 311; the second extension plate 324, on one side of the retraction direction of the first water receiving tray 31, plus the portion of the bottom of the front side wall of the second water receiving tray 32 extending downward and on one side of the retraction direction of the first water receiving tray 31, are covered with the second sealing member 321.

[0089] In this way, when the first water receiving tray 31 is fully extended relative to the second water receiving tray 32, that is, the water receiving tray structure 3 is at the maximum extension length, the contact surface of the first seal 311 can be effectively squeezed with the contact surface of the second seal 321, thereby causing the two to fit tightly, thereby ensuring that condensation water in the first water receiving tray 31 and / or the second water receiving tray 32 will not overflow from between the contact surface of the first seal 311 and the contact surface of the second seal 321.

[0090] In order to ensure that the condensed water in the first water receiving tray 31 and / or the second water receiving tray 32 does not overflow from the gap between the front side wall of the first water receiving tray 31 and the front side wall of the second water receiving tray 32 when the first water receiving tray 31 is fully retracted relative to the second water receiving tray 32, refer to the attached Figure 5 and 9 A third sealing member 312 is provided on the front side wall of the first water receiving tray 31 and along one side of the retracting direction thereof;

[0091] When the first water receiving tray 31 is completely retracted relative to the second water receiving tray 32 , the contact surface of the third sealing member 312 can be tightly fitted with the corresponding front side wall of the second water receiving tray 32 .

[0092] It should be noted that the front side wall of the first water receiving tray 31 has a third extension plate 317 extending vertically outward on both sides of the X-axis direction and toward the corresponding second guide rail 323; therefore, the third extension plate 317 on one side of the retraction direction of the first water receiving tray 31 plus the part of the bottom of the front side wall of the first water receiving tray 31 that extends downward and on one side of the retraction direction of the first water receiving tray 31 are covered with a third sealing member 312.

[0093] In this way, when the first water receiving tray 31 is fully retracted relative to the second water receiving tray 32, the contact surface of the third sealing member 312 can be effectively squeezed against the corresponding front side wall of the second water receiving tray 32, thereby causing the two to fit tightly together, thereby ensuring that condensation water in the first water receiving tray 31 and / or the second water receiving tray 32 will not overflow from between the contact surface of the third sealing member 312 and the front side wall of the second water receiving tray 32.

[0094] It should be noted that the front side wall in this embodiment refers to the side wall of the first water receiving tray 31 and the second water receiving tray 32 on one side of the extension direction of the first water receiving tray 31, and the rear side wall in this embodiment refers to the side wall of the first water receiving tray 31 and the second water receiving tray 32 on the other side of the retraction direction of the first water receiving tray 31.

[0095] Among them, refer to the attached Figure 6 and 9 A gap is provided between the first water receiving tray 31 and the second water receiving tray 32, and a drainage hole 322 is provided at the bottom of the second water receiving tray 32. The drainage hole 322 can discharge the condensed water in the second water receiving tray 32 to the outside through a connected drainage pipe 327;

[0096] When the first water receiving tray 31 is fully retracted relative to the second water receiving tray 32 , there is a flow space between the first water receiving tray 31 and the second water receiving tray 32 in the Y-axis direction (not shown, the same applies to the entire text).

[0097] It should be noted that the length of the first water receiving tray 31 along its Y-axis direction is smaller than the length of the second water receiving tray 32 along its Y-axis direction. In this way, when the water receiving tray structure 3 is in a fully retracted state, the condensation water in the first water receiving tray 31 can still flow smoothly into the drainage hole 322 through the circulation space and gap in turn and be discharged to the outside, thereby preventing excessive accumulation of condensation water in the first water receiving tray 31 and the second water receiving tray 32.

[0098] In order to prevent the first water receiving tray 31 from being fully extended relative to the second water receiving tray 32, the driving device 332 still drives the first water receiving tray 31 to continue to extend outward through the gear 333, resulting in damage to the water receiving tray structure 3, refer to the attached Figure 5 A first pressure sensor 4 is provided on the front side wall of the second water receiving tray 32 and on one side along the retraction direction of the first water receiving tray 31 .

[0099] It should be noted that the first pressure sensor 4 is electrically connected to the main control unit, and the first pressure sensor 4 can also be arranged on the first sealing member 311 or the second sealing member 321, which is not limited here.

[0100] In this way, when the first water receiving tray 31 is fully extended relative to the second water receiving tray 32, the first pressure sensor 4 will be squeezed and generate a first pressure value P1, and at the same time transmit the first pressure value P1 to the main control unit. If the main control unit detects that the first pressure value P1 is greater than or equal to the preset pressure value P0, it will turn off the driving device 332 to prevent the first water receiving tray 31 from continuing to extend relative to the second water receiving tray 32.

[0101] In order to prevent the first water receiving tray 31 from being completely retracted relative to the second water receiving tray 32, the driving device 332 still drives the first water receiving tray 31 to continue to retract inward through the gear 333, causing damage to the water receiving tray structure 3, refer to the attached Figure 5 A second pressure sensor 5 is provided on the front side wall of the first water receiving tray 31 and along one side of its retracting direction.

[0102] It should be noted that the second pressure sensor 5 is electrically connected to the main control unit, and the second pressure sensor 5 can also be arranged on the third sealing member 312 or the front side wall of the second water receiving tray 32 and facing the extension direction of the first water receiving tray 31, which is not limited here.

[0103] In this way, when the first water receiving tray 31 is fully retracted relative to the second water receiving tray 32, the second pressure sensor 5 will be squeezed and generate a second pressure value P2, and the second pressure value P2 will be transmitted to the main control unit. If the main control unit detects that the first pressure value P2 is greater than or equal to the preset pressure value P0, the driving device 332 will be turned off to prevent the first water receiving tray 31 from continuing to retract relative to the second water receiving tray 32.

[0104] Among them, refer to the attached Figure 4 The angled surface 1 is provided with a temperature sensing package 6, and the temperature sensing package 6 is used to detect the surface temperature T1 of the angled surface 1 and the dew point temperature T2 of the environment in which the angled air cooler is located.

[0105] It should be noted that the temperature sensing package 6 is electrically connected to the main control unit.

[0106] In this way, the main control unit can obtain the surface temperature T1 of the angled surface 1 and the dew point temperature T2 of the environment in which the angle air cooler is located through the temperature sensing package 6, and then the main control unit compares the surface temperature T1 with the dew point temperature T2. If T1≤T2, the main control unit will determine that the angled surface 1 has the conditions for condensation to occur. At this time, the main control unit will start the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to extend through the gear 333 until it is fully extended, and then receive the condensation water generated on the evaporator 7, the surface of the two side plates of the angle air cooler along the X-axis direction and the surface of the angled surface 1, thereby ensuring that the condensation water generated by the angle air cooler will not wet the surrounding goods or equipment, thereby improving the anti-condensation effect of the angle air cooler.

[0107] If T1>T2, and the duration t≥preset time t0, the main control unit will determine that the bevel surface 1 does not have the conditions for condensation to occur. Therefore, there are two situations:

[0108] First, if the first water receiving tray 31 is not extended relative to the second water receiving tray 32 , the main control unit will keep the driving device 332 closed.

[0109] Secondly, if the first water receiving tray 31 extends relative to the second water receiving tray 32, the main control unit will start the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to retract inward through the gear 333 until it is fully retracted.

[0110] Example 2

[0111] Based on the same inventive concept, the present invention also proposes a refrigeration device, which includes the above-mentioned angle air cooler.

[0112] In this way, when the refrigeration equipment is started, the angle air cooler operates accordingly. When the surface temperature T1 of the angled surface 1 in the angle air cooler is less than or equal to the dew point temperature T2 of the environment, the water vapor in the air will condense into water droplets on the surface of the angle air cooler to form condensation. At this time, the main control unit will control the first water receiving tray 31 to extend relative to the second water receiving tray 32 through the driving device 332 until it is fully extended, thereby ensuring that the water receiving tray structure 3 can completely receive the condensation water generated by the angle air cooler, thereby ensuring that the condensation water generated by the angle air cooler will not wet the surrounding goods or equipment, thereby improving the anti-condensation effect of the angle air cooler.

[0113] Example 3

[0114] Based on the same inventive concept, refer to the attached Fig.10 The present invention also proposes a control method using the above-mentioned angle air cooler, the control method comprising:

[0115] The main control unit obtains the surface temperature T1 of the bevel surface 1 and the dew point temperature T2 of the environment where the angle air cooler is located through the temperature sensing package 6, and determines whether the surface temperature T1 is greater than the dew point temperature T2;

[0116] If not, the main control unit will determine that the angled surface 1 has the conditions for condensation to occur, and control the water receiving tray structure 3 to switch to a fully extended state; that is, the main control unit starts the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to extend through the gear 333 until it is fully extended, thereby ensuring that the water receiving tray structure 3 can completely receive the condensation water generated by the angle air cooler, thereby ensuring that the condensation water generated by the angle air cooler will not wet the surrounding goods or equipment, thereby improving the anti-condensation effect of the angle air cooler.

[0117] If so, and the duration t is not less than the preset time t0, the main control unit will determine that the angled surface 1 does not have the conditions for condensation to occur, and control the water receiving tray structure 3 to switch to a fully retracted state; that is, it is equivalent to the first water receiving tray 31 extending relative to the second water receiving tray 32. At this time, the main control unit will start the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to retract inward through the gear 333 until it is fully retracted; or the first water receiving tray 31 is not extended relative to the second water receiving tray 32, at this time, the main control unit will keep the driving device 332 closed.

[0118] Further, when the water receiving tray structure 3 extends outward, the control method includes:

[0119] The main control unit obtains a first pressure value P1 according to the first pressure sensor 4, and determines whether the first pressure value P1 is not less than the preset pressure value P0;

[0120] If so, it is determined that the water receiving tray structure 3 is in a fully extended state; at this time, the main control unit will turn off the driving device 332 to prevent the first water receiving tray 31 from continuing to extend relative to the second water receiving tray 32, thereby preventing the water receiving tray structure 3 from being damaged.

[0121] If not, it indicates that the first water receiving tray 31 has not been extended to the maximum extension length relative to the second water receiving tray 32, and the water receiving tray structure 3 can still continue to extend outward; that is, at this time the main control unit will continue to start the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to extend through the gear 333 until it is fully extended.

[0122] Further, when the water receiving tray structure 3 retracts inwardly, the control method includes:

[0123] The main control unit obtains a second pressure value P2 according to the second pressure sensor 5, and determines whether the second pressure value P2 is not less than the preset pressure value P0;

[0124] If so, it is determined that the water receiving tray structure 3 is in a fully retracted state; at this time, the main control unit will turn off the driving device 332 to prevent the first water receiving tray 31 from further retracting relative to the second water receiving tray 32, thereby preventing the water receiving tray structure 3 from being damaged.

[0125] If not, it indicates that the first water receiving tray 31 is not fully retracted relative to the second water receiving tray 32, and the water receiving tray structure 3 can still continue to retract inward; that is, at this time the main control unit will continue to start the driving device 332, so that the driving device 332 drives the first water receiving tray 31 to retract through the gear 333 until it is fully retracted.
