Any implementation described as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, for purposes of explanation, numerous details are set forth. It should be appreciated that there is no intention to limit the application to the exact details as described. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the application. The present application is thus not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.
[0028] As shown in FIG. 1, in one aspect, embodiments of the present application provide a condensate water detection device, which can accurately detect whether condensation occurs on a to-be-detected object, such as a heat exchanger 2, so as to timely guide and discharge the condensate water when the condensation occurs. Figure 1 and Figure 2 As shown in FIG. 1, in one aspect, embodiments of the present application provide a condensate water detection device, which can accurately detect whether condensation occurs on a to-be-detected object, such as a heat exchanger 2, so as to timely guide and discharge the condensate water when the condensation occurs.
[0029] The condensate water detection device includes a power supply module, a conductive circuit 12, and a resistance sensor. The conductive circuit 12 is electrically connected to the positive electrode 111 and the negative electrode 112 of the power supply module, so that an electric current is generated on the conductive circuit 12. The conductive circuit 12 is adapted to be arranged corresponding to a potential condensation part of a to-be-detected object, which can be, for example, an object type with a potential condensation risk, such as a heat exchanger 2 arranged obliquely. When condensation occurs on the potential condensation part of the to-be-detected object, the condensate water can drip onto the surface of the conductive circuit 12. The conductive circuit 12 is configured to change in resistance when contacting the condensate water, and the resistance sensor is used to measure the resistance change of the conductive circuit 12.
[0030] When the potential condensation part of the object to be measured does not actually condense, no condensate drops to the surface of the conductive line 12, and the measurement value of the resistance sensor remains unchanged; when the potential condensation part of the object to be measured actually condenses, the condensate can drop to the surface of the conductive line 12, thereby causing the resistance of the conductive line 12 to change and the measurement value of the resistance sensor to change. In this way, whether the potential condensation part of the object to be measured actually condenses and the severity of the condensation can be more accurately determined by whether the measurement value of the resistance sensor changes and the change amplitude, so that the condensate can be timely drained when condensation occurs.
[0031] In some embodiments, the object to be measured can be a heat exchanger 2 having a plurality of heat exchange fins 21 arranged at intervals. Here, the condensate detection device can include a plurality of conductive lines 12 and a plurality of resistance sensors. The plurality of conductive lines 12 are arranged in parallel between the positive electrode 111 and the negative electrode 112 of the power supply module, the plurality of conductive lines 12 and the plurality of heat exchange fins 21 are arranged one-to-one, and the plurality of resistance sensors and the plurality of conductive lines 12 are arranged one-to-one. In this way, one conductive line 12 and one resistance sensor are arranged corresponding to each heat exchange fin 21, and whether each heat exchange fin 21 condenses and the severity of the condensation can be independently detected, thereby accurately draining the condensate generated on the heat exchange fin 21 that condenses.
[0032] In some examples, the conductive line 12 can be arranged extending along the width direction of the heat exchange fin 21 and located directly below the heat exchange fin 21. In this way, when the heat exchange fin 21 condenses, the condensate generated on any area of the heat exchange fin 21 along the width direction can accurately drop onto the conductive line 12 located directly below, thereby accurately detecting whether the heat exchange fin 21 condenses. In other examples, the conductive line 12 can be arranged extending along the width direction of the heat exchange fin 21 and located on the surface of the heat exchange fin 21.
[0033] In some examples, the heat exchanger 2 can have a refrigerant pipe 22. The refrigerant pipe 22 can pass through the plurality of heat exchange fins 21 in sequence, and at least one conductive line 12 is also arranged corresponding to the refrigerant pipe 22. In other words, at least one conductive line 12 is arranged corresponding to the heat exchange fin 21 to detect whether the heat exchange fin 21 condenses, and is also arranged corresponding to the refrigerant pipe 22 to detect whether the refrigerant pipe 22 condenses, so that the heat exchange fin 21 and the refrigerant pipe 22 can be simultaneously subjected to condensation risk detection.
[0034] Exemplarily, the refrigerant pipe 22 can include a plurality of straight pipe sections 221 and at least one bent pipe section 222. The plurality of straight pipe sections 221 can be sequentially and spacedly arranged along the width direction of the heat exchange fin 21, and two adjacent straight pipe sections 221 are connected by one bent pipe section 222. The conductive circuit 12 sequentially passes through the lower region of the plurality of straight pipe sections 221. In this way, the conductive circuit 12 can detect whether the plurality of straight pipe sections 221 have condensation, and the detection region of the condensate water detection device is increased.
[0035] As shown in FIGS. 1, 2 and 3, in some embodiments, the condensate water detection device can further include a flow guide 13. The flow guide 13 can be moved to below the potential condensation part of the object to be detected, so as to collect the condensate water dripping from the potential condensation part and guide the collected condensate water to the drainage part. By arranging the flow guide 13, when it is determined that the potential condensation part of the object to be detected has condensation, the flow guide 13 can be used to collect and guide the condensate water to the drainage part, and then the condensate water is drained through the drainage part, so as to avoid the condensate water from dripping onto other devices, such as the fan 3, which are located below the object to be detected, and then avoid the risk of damage of the other devices due to moisture. Figure 3 Figure 4 As shown in FIGS. 1, 2 and 3, in some embodiments, the condensate water detection device can further include a flow guide 13. The flow guide 13 can be moved to below the potential condensation part of the object to be detected, so as to collect the condensate water dripping from the potential condensation part and guide the collected condensate water to the drainage part. By arranging the flow guide 13, when it is determined that the potential condensation part of the object to be detected has condensation, the flow guide 13 can be used to collect and guide the condensate water to the drainage part, and then the condensate water is drained through the drainage part, so as to avoid the condensate water from dripping onto other devices, such as the fan 3, which are located below the object to be detected, and then avoid the risk of damage of the other devices due to moisture.
[0036] In some examples, the condensate water detection device can further include a driving member 14 for driving the flow guide 13 to move to below the potential condensation part of the object to be detected. The type of the driving member 14 can be determined according to actual needs, which can contactively drive the flow guide 13 to move, or non-contactively drive the flow guide 13 to move, and the embodiments of the present application do not limit this.
[0037] Exemplarily, the driving member 14 can be an electromagnetic member, which drives the flow guide 13 to move by a non-contact magnetic driving mode. The condensate water detection device further includes an elastic connecting member 16 connected to the flow guide 13. The electromagnetic member generates a magnetic field force when powered on, so as to drive the flow guide 13 to extend to below the potential condensation part of the object to be detected. In this process, the elastic connecting member 16 is elastically deformed to accumulate a reset elastic potential energy. When the electromagnetic member is powered off, the magnetic field force of the electromagnetic member is removed, the reset elastic potential energy of the elastic connecting member 16 is released to generate an elastic reset force, so that the flow guide 13 is reset under the driving of the elastic reset force to be separated from the region below the potential condensation part of the object to be detected, for example, to be reset to a region close to the surface of the heat exchange fin 21.
[0038] For example, the condensed water detection device can further include a guide sleeve 15. The end of the flow guide 13 close to the driving member 14 is slidably arranged in the guide sleeve 15, and the end of the flow guide 13 away from the driving member 14 extends out of the guide sleeve 15 and is slidably arranged below the potential condensation part of the object to be detected. When the heat exchanger 2 has a plurality of heat exchange fins 21 arranged at intervals, the extension direction of the guide sleeve 15 can be inclined or perpendicular to the width direction of the heat exchange fin 21. By arranging the guide sleeve 15, the movement of the flow guide 13 can be accurately guided by the guide sleeve 15, so that the flow guide 13 can accurately move below the potential condensation part of the object to be detected to reliably guide the condensed water.
[0039] The shape of the flow guide 13 can be determined according to actual needs, and the embodiments of the present application do not limit it. In some examples, the flow guide 13 can be an arc-shaped plate. By arranging the flow guide 13 as an arc-shaped plate, the condensed water can flow along the surface of the arc-shaped plate to the drainage part, increasing the flow guiding effect of the flow guide 13.
[0040] As shown in FIG. 1, in some examples, the flow guide 13 can be a plate. The plate can be arranged to be perpendicular to the potential condensation part of the heat exchanger 2, and the plate can be arranged to be perpendicular to the horizontal plane. The plate can be arranged to be perpendicular to the potential condensation part of the heat exchanger 2 and the horizontal plane. Figures 1 to 5 As shown in FIG. 1, in some examples, the flow guide 13 can be a plate. The plate can be arranged to be perpendicular to the potential condensation part of the heat exchanger 2, and the plate can be arranged to be perpendicular to the horizontal plane. The plate can be arranged to be perpendicular to the potential condensation part of the heat exchanger 2 and the horizontal plane.
[0041] The above describes the condensed water detection device and the inter-row air conditioner provided by the embodiments of the present application in detail. The specific examples are applied to explain the principles and implementation modes of the present application, and the above examples are only used to help understand the method and core idea of the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range can be changed, and the above description should not be understood as limiting the present application.
