Description

Technical Field

[0001] The utility model belongs to the technical field of leakage alarm of air conditioner water pan, in particular to an alarm system after overflow of water pan. Background Art

[0002] The existing product water pan design does not have a reliable alarm design for overflow of accumulated water, and does not have an alarm form that responds immediately after overflow. This type of alarm uses leakage sensors in other parts, and triggers the alarm after the accumulated water overflows to the sensor position. Usually, the alarm is only triggered after the overflow water reaches an important part. This type of design has a high probability of failure, which will cause the accumulated water to flow out of the equipment, causing a great impact and loss to the room where it is used. In summary, the following technical problems exist in the existing technology:

[0003] 1. Non-dedicated leakage sensors have a greater risk of failure.

[0004] 2. The alarm is triggered after the overflow water flows to the alarm position, and there is an extremely obvious lag.

[0005] 3. In industrial equipment, if you want to eliminate the possibility of alarm failure, you need more leakage detection points, or you need an extremely long fully enclosed leakage detection belt, which is extremely costly.

[0006] 4. When the existing technical solution triggers the alarm, there must be a large amount of overflow water inside the equipment, and the equipment must be shut down for processing, which will cause significant losses to the user. Utility Model Content

[0007] In order to solve the technical problems existing in the above-mentioned prior art, the utility model provides an overflow alarm system for a water pan, which guides the flow of overflowing water so that it flows to the alarm triggering position as soon as possible, that is, triggers the overflow alarm with a very small amount of water and in the fastest time.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A water pan overflow alarm system, comprising:

[0010] The operation screen is connected to the control module; the control module is respectively connected to the buzzer and the alarm light;

[0011] A water collection tray provided with an overflow port;

[0012] The liquid leakage sensor is connected to the control module, and the overflow port is arranged just above the spatial position of the liquid leakage sensor.

[0013] Furthermore, one end of the capillary is connected to the overflow port, and the other end is connected to the liquid leakage sensor.

[0014] Furthermore, the water collection tray is provided with a flow guiding mechanism, the flow guiding mechanism is located at the bottom of the water collection tray, and the flow guiding mechanism is connected to the liquid leakage sensor.

[0015] Furthermore, the flow guiding mechanism is a hollow cylinder.

[0016] Furthermore, the upper surface of the flow guide mechanism is higher than the bottom surface of the water collection tray.

[0017] Furthermore, the liquid leakage sensor is a point sensor or a belt sensor.

[0018] Furthermore, the overflow port is arranged 1-3 cm away from the top surface of the water collection tray.

[0019] Beneficial effects of the utility model:

[0020] Compared with the prior art, the water pan overflow alarm system described in the utility model has the following beneficial effects:

[0021] 1. This design can set up a dedicated alarm point, or use leakage alarm points at other locations, with extremely low cost.

[0022] 2. The response time of triggering the alarm in this design is extremely short, and the overflow water volume is also very small, reducing the safety hazards caused by overflow.

[0023] 3. Eliminate the possibility of overflow alarm failure, ensure that leakage will definitely alarm, and eliminate the possibility of leakage outside the equipment.

[0024] 4. Safety is the focus of this plan. The direction of overflow water is controlled to fundamentally eliminate major safety issues such as short circuits caused by overflow water.

[0025] 5. By guiding a small amount of overflow water, the overflow alarm can be triggered quickly and effectively. Most air conditioners, such as those with independent air ducts and units, can handle and eliminate overflow alarms without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly illustrate the technical solution of the implementation of the utility model, the utility model will be described in detail below in combination with the drawings and detailed implementation. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative labor. Among them:

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Figure 1-2 The new precise and reliable electrical box heat dissipation and electrical component temperature control system is further explained.

[0031] The utility model relates to an alarm system after overflow of an air conditioner water pan. The device is located inside the air conditioner and is mainly used for collecting condensed water and discharging it. Generally, a natural drainage method is selected, and the accumulated water is naturally discharged to the outside through gravity.

[0032] The refrigeration coil of the air conditioner will continuously condense condensed water, which will collect in the water pan. For some equipment with humidifiers, the humidifier may also have water flowing into the water pan. Under normal circumstances, after the water flows into the water pan, it will be discharged to the outside of the air conditioner through the drainage pipe or drainage pump. When a fault occurs, the drainage pipe or drainage pump fails for some reason and cannot drain the accumulated water smoothly, and the accumulated water will overflow the water pan.

[0033] like Figure 1 As shown, the water pan 3 is usually in the form of a sloped bottom and an open top. The overflow position is random, and the top edge is a potential overflow position, and overflow may occur. The common effective height of the drain pan is 5-10cm, and a hole is opened 1-3cm from the top surface, which ensures that the drain pan can store a small amount of water when the drainage pipeline is temporarily blocked or the amount of condensed water increases for a short time, and drain it after it returns to normal, reducing the risk of overflow shutdown. At the same time, it also ensures that before the accumulated water overflows the top of the drain pan, a small amount of accumulated water is drained from the overflow hole to trigger the overflow alarm and minimize losses.

[0034] Example 1

[0035] A water pan overflow alarm system, comprising:

[0036] The operation screen is connected to the control module; the control module is respectively connected to the buzzer and the alarm light;

[0037] A water collection tray 3, which is provided with an overflow port 1;

[0038] The liquid leakage sensor is connected to the control module, and the overflow port 1 is arranged just above the spatial position of the liquid leakage sensor.

[0039] like Figure 1As shown, a special overflow port 1 is opened at a distance from the top, and the overflow port 1 is set just above the spatial position of the leakage sensor (either a point sensor or a belt sensor), that is, the overflow water drips through the overflow port and directly drips to the alarm trigger position of the leakage sensor, triggering the leakage sensor to act, and the leakage sensor sends a signal to the control module, and the control module sends the signal to the operation screen, the alarm light and the buzzer, and the equipment operation screen, the alarm light and the buzzer simultaneously issue a leakage alarm.

[0040] Example 2

[0041] A water pan overflow alarm system, comprising:

[0042] The operation screen is connected to the control module; the control module is respectively connected to the buzzer and the alarm light;

[0043] A water collection tray 3, which is provided with an overflow port 1;

[0044] A liquid leakage sensor connected to the control module;

[0045] It also includes a capillary tube, one end of which is connected to the overflow port 1, and the other end of which is connected to the liquid leakage sensor.

[0046] After opening a hole 1-3cm away from the top surface of the water pan, the overflow hole 1 is connected to the leakage alarm trigger point of the leakage sensor through a capillary tube, that is, after the accumulated water passes through the overflow hole 1, it is retained to the leakage sensor alarm trigger point through the capillary tube. At this time, the hole position only needs to consider the plane direction position to facilitate the pipeline arrangement. This solution can be applied to the scene where the module distribution in the air conditioner cannot meet the requirements of Example 1, and the same effect can be achieved.

[0047] Example 3

[0048] A water pan overflow alarm system, comprising:

[0049] The operation screen is connected to the control module; the control module is respectively connected to the buzzer and the alarm light;

[0050] A water collection tray 3, which is provided with an overflow port 1;

[0051] The liquid leakage sensor is connected to the control module, and the overflow port 1 is arranged just above the spatial position of the liquid leakage sensor.

[0052] The water collection tray 3 is also provided with a flow guiding mechanism 2, which is located at the bottom of the water collection tray 3, connected to the liquid leakage sensor, and is a hollow cylinder. The upper surface of the flow guiding mechanism 2 is higher than the surface of the bottom of the water collection tray 3.

[0053] Furthermore, the overflow port 1 is arranged at a distance of 1-3 cm from the top surface of the water collection tray 3 .

[0054] An overflow hole 1 is provided in the water accumulation tray, and a flow guiding mechanism 2 is provided on the bottom plate, the starting point of the flow guiding mechanism 2 is the dripping position of the accumulated water, and the end point is the alarm triggering point of the liquid leakage sensor. This embodiment is applicable when both embodiments 1 and 2 are unavailable.

[0055] The utility model can set up a dedicated alarm point, or use leakage alarm points at other positions, with extremely low cost; the response time for triggering the alarm is extremely short, and the overflow water volume is also very small, reducing the safety hazards caused by overflow; eliminating the possibility of overflow alarm failure, ensuring that leakage will definitely alarm, and eliminating the possibility of leakage outside the equipment.

[0056] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
