Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model. The following embodiments and features of the embodiments may be combined with each other without conflict.

In the prior art, an air conditioning system on an automobile can refrigerate, heat and ventilate air in a carriage and purify the air. The evaporator is used as a heat exchange device of an automobile air conditioning system and is mainly used for absorbing heat and refrigerating, and transferring the heat of the outside air to the liquid refrigerant to enable the liquid refrigerant to be in a gaseous state. During the heat absorption process of the evaporator, because the temperature of the evaporator is low, the wet and hot water vapor in the air can form condensed water on the surface of the evaporator and is converged into the bottom of the air conditioning box shell.

In order to avoid that the condensate water excessively affects the normal operation of the air conditioning system, a drain outlet is usually formed in the bottom of the air conditioning box shell, and a drain pipe is connected to the drain outlet, so that the condensate water is discharged from the air conditioning box shell through the drain pipe.

In the actual use process of the automobile, the foreign matters such as insects, miscellaneous soil and the like inevitably enter the air conditioning box shell from the air duct of the air conditioner, and part of the foreign matters also can block the water outlet and the water drain pipe of the air conditioning box shell. In addition, part of the vehicle maintenance service stations have the phenomenon of irregular installation operation, so that the drain pipe can be twisted and extruded during installation, and the drain pipe can be prevented from draining condensed water. When the water outlet or the water drain pipe is blocked by foreign matters or the water drain pipe is bent and twisted, condensed water cannot be effectively drained, and the condensed water can be continuously accumulated in the air conditioner box shell, so that the liquid level of the condensed water is continuously increased.

Along with the rising of the liquid level of the condensed water, the condensed water can seep out of the connecting gap of the air conditioner box shell and enter the cab, and at the moment, if an electric element is assembled on the bottom plate of the cab, the electric element is damaged, the function of the electric element is lost, and the driving safety is also influenced when serious.

Therefore, if the drain outlet and the drain pipe cannot be found in time to be blocked, condensed water is accumulated and cannot be overhauled in time, the liquid level of the condensed water in the air conditioner box shell continuously rises and seeps out from the connecting gap of the air conditioner box shell, and then the exudation fault of the automobile is caused.

In order to overcome the defects in the prior art, the utility model provides an air conditioner drain pipe blockage monitoring device and a vehicle, so that when the liquid level of condensed water rises to a preset liquid level, a fault signal is sent out timely, and the exudation fault of an automobile is avoided.

The present utility model will be described in detail with reference to the accompanying drawings so that those skilled in the art can more clearly understand the present utility model.

The following describes in detail an air conditioner drain pipe clogging monitoring device and a vehicle provided by the present utility model with reference to fig. 1 to 7.

As shown in fig. 1, 2 and 5, the present embodiment provides an air conditioning case drain pipe blockage monitoring device, which includes an air conditioning case housing 100 and a condensate level detector 200, wherein the air conditioning case housing 100 has a first accommodating chamber 110 therein, the first accommodating chamber 110 is used for accommodating an evaporator, and a first mounting hole 111 communicating with the first accommodating chamber 110 is formed on a side wall of the air conditioning case housing 100. And the condensed water level detector 200 includes a mounting base 210 and a detecting assembly 220, the mounting base 210 is connected with the first mounting hole 111, the mounting base 210 is provided with a second accommodating cavity 2111 therein, the second accommodating cavity 2111 is communicated with the first accommodating cavity 110, and the detecting assembly 220 is arranged in the second accommodating cavity 2111. When the condensed water generated by the evaporator rises to a preset liquid level, the detection assembly 220 is turned on by the condensed water and sends a fault signal to the vehicle.

It will be appreciated that since the first receiving chamber 110 of the air conditioning case housing 100 and the second receiving chamber 2111 of the mounting base 210 communicate through the first mounting hole 111, and the first mounting hole 111 is located at a lower position of the side wall of the air conditioning case housing 100, that is, the condensed water level detector 200 is located at a lower position of the side wall of the air conditioning case housing 100. The condensed water on the surface of the evaporator will flow into the second accommodation chamber 2111 after accumulating to some extent, and the condensed water level in the first accommodation chamber 110 is kept consistent with the condensed water level in the second accommodation chamber 2111, and thus rises. When the level of the condensed water rises to a preset level, it is brought into contact with the detecting member 220 provided in the second accommodation chamber 2111, and the detecting member 220 is conducted through the condensed water due to the conductivity of the water, and transmits a malfunction signal to the vehicle.

Therefore, according to the blockage detection device for the drain pipe of the air conditioner provided by the utility model, the condensed water level detector 200 is arranged on the air conditioner shell 100, so that the detection component 220 of the condensed water level detector 200 is conducted when the condensed water rises to the preset liquid level, and a fault signal is sent to a vehicle.

With this, realize that in outlet and drain pipe jam of air conditioning case, unable effective drainage comdenstion water leads to first holding chamber 110 and second holding chamber 2111 in the excessive time of comdenstion water of accumulation, in time send fault signal to the vehicle, remind the user to overhaul. Finally, the purpose of avoiding the continuous accumulation of condensed water, oozing out of the connecting gap of the air conditioning case housing 100, entering the cockpit, damaging the electric devices on the vehicle and further causing oozing out faults of the vehicle is achieved.

In some embodiments, as shown in fig. 2-4, the probe assembly 220 includes at least two probe elements, the mount 210 includes a first mounting section 211 and a second mounting section 213, the second mounting section 213 is located laterally of the first mounting section 211, the second receiving cavity 2111 is located within the first mounting section 211, and the first mounting section 211 is connected to the first mounting hole 111. The second mounting section 213 has a third accommodation chamber 2131 therein, and the probe element portion is partially inserted into the second accommodation chamber 2111 through the third accommodation chamber 2131.

As shown in fig. 4, it will be understood that the detection assembly 220 is configured to include at least two detection elements, i.e., at least one group of detection elements, so as to better meet the requirement of using the condensed water to conduct the detection assembly 220, where the detection elements are preferably configured to be two, i.e., one group of detection elements, and the lower ends of the two detection elements should be kept flush, so that the condensed water can be simultaneously contacted and conducted with the two detection elements.

Alternatively, four or more detecting elements, i.e., two or more groups, may be provided to improve the accuracy of detecting the condensed water level. Or in order to meet different liquid level detection requirements, the lower ends of the detection elements can be set to correspond to different preset liquid levels so as to conduct different groups of detection elements at different liquid level heights and send fault signals with different fault levels to the vehicle, and the embodiment is not limited herein.

In addition, more than two detection elements are arranged, and the higher detection reliability can be provided by using the more than two detection elements. When the original detection element for conducting the condensate level detector 200 is damaged, the other detection elements are also used for conducting, so that the condensate level detector is prevented from being invalid due to the damage of the detection element. As shown in fig. 3, it can be understood that the mounting base 210 is divided into the first mounting section 211 and the second mounting section 213, and the second mounting section 213 is disposed at a side of the first mounting section 211, so that the condensation water level detector 200 of the drain pipe blockage monitoring device of the air conditioner box can be disassembled and assembled more conveniently and rapidly to meet different mounting requirements. For example, when the condensation water level detector 200 needs to be connected with the first mounting hole 111, the first mounting section 211 can be utilized to complete connection, and when only the detection assembly 220 on the condensation water level detector 200 needs to be disassembled, the second mounting section 213 can be operated from the side after the whole condensation water level detector 200 is disassembled, so that the detection assembly 220 is prevented from being disassembled from the first mounting section 211, the whole disassembly operation is more refined, and the operation is convenient and efficient.

In addition, the mounting base 210 is divided into the first mounting section 211 and the second mounting section 213, and correspondingly, the internal space of the mounting base 210 is also divided into the second accommodating cavity 2111 and the third accommodating cavity 2131, so that different accommodating requirements can be respectively realized by using the second accommodating cavity 2111 and the third accommodating cavity 2131, and the accommodating function of the mounting base 210 is more comprehensive.

It should be noted that, while the second accommodation chamber 2111 and the third accommodation chamber 2131 are defined in the mounting base 210, the two accommodation chambers are not completely separated, and a part of the structure of the detecting element is accommodated therebetween, so that functions of part of the structures of the detecting assemblies 220 located in different accommodation chambers are reasonably partitioned.

In some embodiments, as shown in fig. 4, the probe element includes a card terminal 222, a card end seat 223 and a metal probe 221, where the card terminal 222 and the metal probe 221 are disposed on the card end seat 223, and the card terminal 222 is coaxially connected to the metal probe 221 and respectively located at opposite ends of the card end seat 223. The card terminal 222 and the card terminal seat 223 are positioned in the third accommodation chamber 2131, the card terminal seat 223 is abutted against the third accommodation chamber 2131, the metal probes 221 are inserted into the second accommodation chamber 2111 through the third accommodation chamber 2131, and when the condensate water rises to a predetermined level, the two metal probes 221 are conducted by the condensate water. The plug-in terminal 222 is used for being electrically connected with the controller 300 of the vehicle, so that when the two metal probes 221 are conducted through condensed water, the controller 300 controls the vehicle to send a fault signal.

In addition, the metal probe 221 is used to contact with the condensed water when the condensed water level rises to the preset level, so that the metal probe 221 is conducted through the condensed water to trigger the plug-in terminal 222 to send a fault signal to the controller 300. The insert terminal seat 223 is disposed between the third accommodation chamber 2131 and the second accommodation chamber 2111, and provides stable and reliable mounting and supporting for the metal probe 221 and the insert terminal 222.

It will be appreciated that coaxially connecting the insert terminal 222 to one end of the metal probe 221 and inserting the metal probe 221 into the insert terminal seat 223 may facilitate connection of the probe element to the mount 210. Wherein two metal probes 221 are provided corresponding to two probe elements, and in other embodiments, the number of metal probes 221 is not particularly limited.

In addition, since the card terminals 222 and the metal probes 221 are located at the opposite ends of the card terminal seat 223, the functions of the partial structures of the probe assemblies 220 located in different accommodating cavities are reasonably partitioned correspondingly.

That is, the metal probe 221 is inserted into the second accommodation chamber 2111 through the third accommodation chamber 2131, and is brought into contact with and conducted with the condensed water when the condensed water in the second accommodation chamber 2111 rises to a predetermined level. The card terminal 222 and the card end seat 223 are then positioned in the third accommodation chamber 2131, the card end seat 223 is abutted against the end of the third accommodation chamber 2131, the third accommodation chamber 2131 is separated from the second accommodation chamber 2111, on the one hand, the metal probe 221 and the card terminal 222 are fixed, on the other hand, condensed water is prevented from entering the third accommodation chamber 2131 from the second mounting hole 212, and finally, a fault signal is sent to the controller 300 connected with the card terminal 222. By the arrangement, the detection accuracy of the condensed water level detector 200 in the using process can be higher, and the safety performance is also higher.

In some embodiments, the detecting element further includes a first sealing ring 224, the first sealing ring 224 is sleeved on the metal probe 221, and the first sealing ring 224 abuts against the insert end seat 223, and the first sealing ring 224 also abuts against the third accommodating cavity 2131.

It will be appreciated that the first sealing ring 224 is sleeved on the metal probe 221, and the first sealing ring 224 is made to abut against the insert end seat 223 and the third accommodating cavity 2131 at the same time, that is, the first sealing ring 224 is located between the insert end seat 223 and the third accommodating cavity 2131. By providing the first seal ring 224, the sealability between the metal probe 221 and the card end seat 223 can be improved. And the first sealing ring 224 can also improve the tightness between the second accommodating cavity 2111 and the third accommodating cavity 2131, so as to avoid that the water vapor of the condensed water in the second accommodating cavity 2111 diffuses into the third accommodating cavity, so as to adversely affect the electrical connection structure between the plug-in terminal 222 in the third accommodating cavity 2131 and the controller 300.

It should be noted that the detecting element used in the present embodiment may be a conventional detecting element known to those skilled in the art, which is not limited in the present utility model.

In some embodiments, the end of the second mounting section 213 facing the first mounting section 211 has a second mounting hole 212, and the third accommodation chamber 2131 communicates with the second accommodation chamber 2111 through the second mounting hole 212, and the metal probe 221 is partially inserted into the second accommodation chamber 2111 through the second mounting hole 212.

It can be appreciated that the sealing performance between the insert end seat 223 and the second mounting hole 212 can be further improved by the first sealing ring 224, so that the condensation water level detector 200 is more compact. And the provision of the second mounting holes 212 can also provide mounting locations for the card end sockets 223, the metal probes 221, and the card terminals 222 so that the probe elements can be more conveniently mounted between the first mounting section 211 and the second mounting section 213.

In some embodiments, the side of the third receiving cavity 2131 facing the second mounting hole 212 has a positioning segment, within which the first seal ring 224 and a portion of the insert end seat 223 are located and abut.

It will be appreciated that when it is desired to remove the condensate level detector 200 for servicing the detection assembly 220, the third receiving chamber 2131 needs to be provided with a relatively large size, and the detection element itself is of a small size, in order to facilitate the replacement of the detection element within the third receiving chamber 2131, and therefore a locating section needs to be provided between the third receiving chamber 2131 and the second receiving chamber 2111. A thicker solid is disposed in the third accommodating cavity 2131 towards the second mounting hole 212, and the second mounting hole 212 is located at the solid for the insert end seat 223 and the metal probe 221 to pass through, and grooves and sockets matched with the shape structure of the insert end seat 223 are disposed at the periphery of the second mounting hole 212, and the grooves and the sockets are positioning sections, so that the insert end seat 223 can be matched and fixed on the second mounting hole 212 of the mounting seat 210 conveniently, the mounting operation of the insert end seat 223 is simplified, namely, the mounting operation of the detection assembly 220 is simplified, and the first sealing ring 224 is located in the positioning section, so that the first sealing ring 224 can be better fixed at a set position.

In this way, when the probe element is mounted in the second mounting hole 212, the metal probe 221 and the card terminal 222 are simply inserted into the card end seat 223, and the card end seat 223 is inserted into the second mounting hole 212 to match with the positioning section.

In some embodiments, as shown in fig. 2 and 3, the end of the first mounting section 211 facing the first mounting hole 111 has at least two buckles 214, and the buckles 214 are inserted into the first mounting hole 111 and are engaged with the first mounting hole 111. The end of the first mounting section 211 facing the first mounting hole 111 has a second seal 2141 between the side wall of the air conditioning case housing 100.

It can be understood that in this embodiment, the end of the first mounting section 211 facing the first mounting hole 111 has four buckles 214, corresponding to the four buckles 214, the first mounting hole 111 is provided with slots having the same number as the buckles 214, and the buckles 214 of the first mounting section 211 are inserted into the slots and rotated to a predetermined angle, so that the clamping connection between the first mounting section 211 and the first mounting hole 111 can be completed. In addition, the first mounting hole 111 is further provided with a sealing ring mounting groove, and the second sealing ring 2141 is mounted in the sealing ring mounting groove, so that the tightness between the air-conditioning case housing 100 and the mounting seat 210 can be effectively improved, and leakage of condensed water from a connection gap between the air-conditioning case housing 100 and the mounting seat 210 is avoided.

In some embodiments, as shown in fig. 5 and 6, the sidewall of the air conditioning case housing 100 has a connection ring 215 provided around the circumference of the first mounting hole 111, and the first mounting section 211 is screw-coupled with the connection ring 215.

That is, in some examples, the connection between the first mounting section 211 and the first mounting hole 111 may also be replaced by a snap-fit connection. It is therefore necessary to provide an external thread structure on the first mounting hole 111 and a connecting ring 215 adapted to the first mounting hole 111 on the first mounting section 211, and an internal thread structure is provided in the connecting ring 215 to realize the connection therebetween, whereby the provision of the second seal 2141 can also be omitted.

It is to be understood that the internal and external positional relationship between the first mounting section 211 and the screw structure of the first mounting hole 111 may be specifically set as required, and the embodiment is not particularly limited herein.

It should be noted that, in the present embodiment, the connection relationship between the first mounting section 211 and the first mounting hole 111, whether a clamping connection or a threaded connection, or other removable connection relationship, is used to achieve the purpose of separability between the air conditioning case housing 100 and the mounting base 210. Thus, when the air conditioning case housing 100 fails in drainage, the user is difficult to effectively dredge the drain outlet or the drain pipe directly, the mounting seat 210 can be detached, foreign matters at the drain outlet are cleaned from the first mounting hole 111 by using other tools, or condensed water is discharged from the first mounting hole 111, and the whole air conditioning case housing 100 is not required to be detached for treatment, so that the convenience of treatment when the drain pipe of the air conditioning case is blocked is improved.

As shown in fig. 7, the present embodiment further provides a vehicle, which includes a controller 300, an air conditioner, and an air conditioner drain pipe blockage monitoring device provided in any of the foregoing embodiments, wherein the air conditioner drain pipe blockage monitoring device is disposed in the air conditioner, and a detection component 220 of the air conditioner drain pipe blockage monitoring device is electrically connected with the controller 300; the air conditioner includes a compressor 500 and a blower 600, the compressor 500 and the blower 600 being electrically connected to the controller 300, and the controller 300 controlling the compressor 500 and the blower 600 to reduce the rotation speed or stop when the detection assembly 220 transmits a fault signal to the controller 300.

It will be appreciated that by electrically connecting the detection assembly 220 of the on-board air conditioner drain blockage monitoring device to the controller 300 and electrically connecting the controller 300 to the compressor 500 and blower 600, the monitoring process of the on-board air conditioner drain blockage monitoring device may be improved. When the condensate water level is too high and the user cannot overhaul and process in time, certain countermeasures are automatically taken, so that unnecessary losses are avoided because the countermeasures cannot be made after the condensate water level detector 200 sends out a fault signal. However, since the compressor 500 and the blower 600 are electrically connected to the controller 300, when the detection assembly 220 transmits a fault signal to the controller 300, the controller 300 controls the compressor 500 and the blower 600 to reduce the rotation speed or stop, and the refrigerating effect of the air conditioner will be low or even zero at this time, so that the surface of the evaporator can be prevented from continuously generating condensed water, and the normal operation can not be restored until the user finishes the maintenance treatment.

In some embodiments, the vehicle further includes an onboard display 400, the onboard display 400 being electrically coupled to the controller 300, and the controller 300 controlling the onboard display 400 to turn on the fault indicator when the detection assembly 220 sends a fault signal to the controller 300.

It can be appreciated that by arranging the vehicle-mounted display 400, when the detecting component 220 sends a fault signal, the fault indicator lamp of the vehicle-mounted display 400 is utilized to perform early warning prompt, so that a user can find drain pipe blockage faults more timely, and overhaul and process in time.

The specific operation of the air conditioner drain pipe blockage monitoring device is described in detail below with reference to fig. 7.

When the drain pipe on the air conditioning case housing is blocked or distorted, and the air conditioner is in a cooling condition, the evaporator condensate water cannot be discharged, and when the condensate water level rises to a preset level, the condensate water level detector 200 is turned on, and then a fault signal is sent to the controller 300. When the controller 300 receives the fault signal, a control signal is issued to the compressor 500 and the blower 600. After the compressor 500 and the blower 600 receive the control signal, the controller 300 controls the compressor 500 and the blower 600 to reduce the rotation speed or stop working until the drain pipe blockage problem is solved, and after the condensed water level detector is disconnected, the normal working is restored. Meanwhile, after the controller 300 receives the fault signal, the control signal is sent to the vehicle-mounted display 400, and after the vehicle-mounted display 400 receives the control signal, the fault indicator is turned on to prompt a user to overhaul until the drain pipe blockage problem is solved, and after the condensed water liquid level detector is disconnected, the fault indicator is turned off.

In summary, according to the air conditioner drain pipe blockage monitoring device and the vehicle provided by the embodiment, the condensation water level detector 200 is installed on the air conditioner casing 100, so that the condensation water level detector 200 is turned on when the condensation water reaches the preset liquid level, and a fault signal is sent to the vehicle, and after the controller 300 of the vehicle receives the fault signal, on one hand, the compressor 500 and the blower 600 are controlled to reduce the rotation speed or stop, and on the other hand, the vehicle-mounted display 400 is controlled to turn on the fault indicator. Therefore, when the drain outlet and the drain pipe of the air conditioning box are blocked, and condensed water cannot be effectively drained, the treatment is timely carried out, and a user is reminded to overhaul, so that condensed water is prevented from seeping out from the connecting gap of the air conditioning box shell 100, entering the cockpit, damaging electric devices on the vehicle, and further causing the exudation fault of the vehicle.
