[0021] The following uses specific embodiments to further illustrate the present utility model:

[0022] This embodiment provides a condensate evaporator water tank with liquid level detection.

[0023] It should be noted that in this embodiment, the air conditioner is a vehicle air conditioner, which is installed in the machine room of the vehicle to provide a suitable temperature environment for the machine room of the vehicle.

[0024] For the vehicle air conditioner, a condensate evaporator is configured. Those skilled in the art can understand that the condensate evaporator is used to convert the condensate generated during the operation of the air conditioner into water vapor and release it into the atmosphere, thereby avoiding the accumulation and discharge of air conditioner condensate.

[0025] Those skilled in the art can also understand that the condensate evaporator has a water tank for storing air conditioner condensate, and a heating device is also provided for the water tank. The heating device is used to heat the air conditioner condensate in the water tank, and by heating, the air conditioner condensate in the water tank is caused to evaporate and become water vapor and release it into the atmosphere.

[0026] The condensate evaporator water tank of this embodiment is improved on the basis of the original water tank.

[0027] Specifically,

[0028] Referring to Figure 1 , the condensate evaporator water tank of this embodiment is further provided with a liquid level detection device 3. The liquid level detection device 3 is used to detect the water level height in the water tank 4, and then automatically control the start and stop of the heating device according to the water level height in the water tank 4.

[0029] More specifically,

[0030] Referring to Figure 2 , three liquid level probes are provided on the liquid level detection device 3, namely a low liquid level probe 31, a middle liquid level probe 32 and a high liquid level probe 33.

[0031] It should be noted that the basic configurations of the three liquid level probes are the same. They are overall in the shape of long needles, and their lower ends are used as detection ends. When the liquid level probe contacts the water body, an electric current loop will be formed. By measuring the change in the resistance value within the electric current loop, the detection result of "whether the liquid level probe contacts the water body" can be detected. Based on this detection result, some automatic control effects can be achieved.

[0032] The differences among the three liquid level probes are that their lengths are different. Among them, the low liquid level probe 31 has the longest length, the middle liquid level probe 32 has the second longest length, and the high liquid level probe 33 has the shortest length.

[0033] The liquid level detection device 3 is further provided with an audible and visual alarm (not shown in the figure), and the audible and visual alarm can emit audible and visual alarm signals.

[0034] The liquid level detection device 3 is assembled on the top of the water tank 4, and the detection ends of the three liquid level probes all face downward and extend into the inner side of the water tank 4. Among the three liquid level probes, the low liquid level probe 31 has the deepest penetration depth, the medium liquid level probe 32 has the second deepest penetration depth, and the high liquid level probe 33 has the shallowest penetration depth; that is to say, the penetration depths of the low liquid level probe 31, the medium liquid level probe 32, and the high liquid level probe 33 into the inner side of the water tank 4 are in turn from deep to shallow.

[0035] The sound and light alarm is located on the outer side of the top of the water tank 4.

[0036] In addition, in the condensate evaporator, a system controller is also provided for the liquid level detection device 3, and the liquid level detection device 3 and the heating device are both electrically connected to the system controller. The system controller can receive the sensing signals of the low liquid level probe 31, the medium liquid level probe 32, and the high liquid level probe 33, and the heating device and the sound and light alarm are both controlled by the system controller.

[0037] The system controller can implement the function of "receiving the sensing signals of the low liquid level probe 31, the medium liquid level probe 32, and the high liquid level probe 33, and then controlling the start and stop of the heating device and the alarm of the sound and light alarm according to the sensing signals". Or it can also be said that the "start and stop of the heating device" and the "alarm of the sound and light alarm" are both controlled by the signals of the low liquid level probe 31, the medium liquid level probe 32, and the high liquid level probe 33 detecting the water level in the water tank 4.

[0038] A network communication module is also provided in the system controller, and the system controller can send the detection data of the low liquid level probe 31, the medium liquid level probe 32, and the high liquid level probe 33 externally through the network communication module, such as sending it to the monitoring terminal of relevant staff.

[0039] The working principle of the condensate evaporator water tank in this embodiment is as follows:

[0040] The operation of the air conditioner generates air conditioner condensate water, and this air conditioner condensate water is introduced into the condensate water evaporator water tank for storage. The liquid level detection device 3 continuously detects the water level in the water tank 4. When the middle liquid level probe 32 detects water, that is, when the water level in the water tank 4 reaches the position of the detection end of the middle liquid level probe 32, the heating device is controlled to start, and the water in the water tank 4 is heated to evaporate the water in the water tank 4. When the low liquid level probe 31 does not detect water, that is, when the water level in the water tank 4 is lower than the position of the detection end of the low liquid level probe 31, the heating device is controlled to shut down to avoid dry burning of the heating device. When the high liquid level probe 33 detects water, that is, when the water level in the water tank 4 reaches the position of the detection end of the high liquid level probe 33, the sound and light alarm is controlled to emit a sound and light alarm signal to alert the on-site staff. And, the alarm information is sent to the relevant operators through the network communication module. And, the air conditioner unit is controlled to stop running, and the air conditioner unit is restarted when the water level in the water tank 4 drops to the detection end of the middle liquid level probe 32.

[0041] It should be noted that in this embodiment, the liquid level detection device 3 is constructed based on a wiring screw 35. Taking the wiring screw 35 as the base, the low liquid level probe 31, the middle liquid level probe 32, the high liquid level probe 33 and the sound and light alarm are all installed on the wiring screw 35, thus constructing a complete liquid level detection device 3. The wiring screw 35 is assembled on the top of the water tank 4 through a thread and a gasket, thus realizing that the "liquid level detection device 3 is assembled on the top of the water tank 4".

[0042] In this embodiment, the liquid level detection device 3 is assembled at the corner of the water tank 4. Then, two partition plates, namely the first partition plate 1 and the second partition plate 2, are arranged inside the water tank 4 for the liquid level detection device 3. These two partition plates enclose the liquid level detection device 3 at the corner of the water tank 4, thus isolating the area where the liquid level detection device 3 is located from the main area inside the water tank 4, preventing the situation of "the water in the water tank 4 boils due to heat, causing the liquid level to fluctuate and resulting in inaccurate water level detection by the liquid level probe".

[0043] It should be noted that neither the first partition plate 1 nor the second partition plate 2 completely separates the water body. The first partition plate 1 and the second partition plate 2 are arranged in a vertically offset manner. That is, the second partition plate 2 is completely isolated at the top of the water tank 4 and open at the lower part of the water tank 4; the first partition plate 1 is completely isolated at the lower part of the water tank 4 and open at the top of the water tank 4. Such an arrangement form not only achieves the effect of isolating water body fluctuations but also does not hinder water body flow.

[0044] In addition, in order to further facilitate water body flow, through holes 5 are opened on both partition plates.

[0045] It should be noted that in this embodiment, the horizontal vertical distance between the detection ends of the low liquid level probe 31 and the middle liquid level probe 32 is set to 40 mm. That is to say, the difference in the detected water levels between the two is 40 mm.

[0046] The condensate evaporator water tank of this embodiment is provided with a liquid level detection device 3. The low liquid level probe 31, the middle liquid level probe 32 and the high liquid level probe 33 of the liquid level detection device 3 can respectively detect the low, middle and high water level heights in the water tank 4. Then, according to the detected water level height in the water tank 4, the start and stop of the heating device are controlled. When the water level is appropriate, the heating device is started. When the water level is too low, the heating device is shut down. In this way, the automatic control of the heating device is realized. In particular, it can prevent the heating device from dry burning, so that the condensate evaporator can operate normally while ensuring safety.

[0047] In addition, when the water level in the water tank 4 is detected to be too high, an alarm signal is issued, including controlling the sound and light alarm to emit a sound and light alarm signal, sending the alarm information to relevant operators through the network communication module, and controlling the air conditioning unit to stop running.

[0048] All in all, the condensate evaporator water tank of this embodiment can realize the functions of automatic control start and stop of the heating device and fault warning, and the cost required for the scheme implementation is relatively low.

[0049] The above are only the preferred embodiments of the present invention, and are not used to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
