Specifically, during the operation of the unit, the internal environment of the unit is a negative pressure environment. The water seal device utilizes the pressure difference during the discharge of condensed water to overcome the pressure during the operation of the unit to ensure the smooth discharge of condensed water; at the same time, the water seal device can prevent air leakage from the unit, that is, prevent air inside the unit from leaking out from the drain outlet of the water seal device or air outside the unit from entering the unit through the drain outlet.

A height difference is set between the water seal device and the air conditioner unit during engineering installation. The water seal device discharges the condensed water of the unit through the height difference with the air conditioner unit, as Figure 1 shown. However, when a variable frequency fan is used in the unit, the internal pressure of the unit will change according to the fan speed. When the operating pressure of the unit changes, since the installation position of the existing water seal device is fixed, its drainage water pressure cannot be adjusted according to the operating pressure of the unit, which is not conducive to the drainage of the unit, resulting in the condensed water in the water receiving tray of the unit not being able to be discharged, and water accumulation affecting the quality of the unit.

[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work fall within the scope protected by the present invention.

[0025] The following will combine the description with the attached Figure 2 drawings, as well as Embodiments 1 and 2, to describe the water seal device and the air conditioner unit of the present invention in detail.

[0026] Embodiment 1

[0027] This embodiment will describe the water seal device of the present invention in detail.

[0028] The water seal device of this embodiment includes a drainage component and an adjustment component. Among them, the drainage component is used to drain the condensate in the air conditioner unit. One end of the drainage component is connected to the drainage port of the air conditioner unit, and an adjustment component is provided at the other end of the drainage component. And the adjustment component adjusts the height of the other end of the drainage component based on the change of the operating pressure of the air conditioner unit.

[0029] Preferably, when the negative pressure inside the air conditioner unit increases, the adjustment component adjusts the height of the other end of the drainage component in the direction of increasing the height difference between the two ends of the drainage component; when the negative pressure inside the air conditioner unit decreases, the adjustment component adjusts the height of the other end of the drainage component in the direction of decreasing the height difference between the two ends of the drainage component. That is, when the negative pressure inside the air conditioner unit increases, the adjustment component adjusts the height of the other end of the drainage component in the downward direction, so as to increase the height difference between the two ends of the drainage component, so that the condensate in the water receiving tray of the air conditioner unit can be drained. When the negative pressure inside the air conditioner unit decreases, the adjustment component adjusts the height of the other end of the drainage component in the upward direction, so as to reduce the height difference between the two ends of the drainage component.

[0030] When the operating pressure of the air conditioner unit changes, the water seal device of this embodiment can adjust the height of the other end of the drainage component through the adjustment component, so as to adjust the height difference between the two ends of the drainage component, and then the condensate in the water receiving tray of the air conditioner unit can be drained, avoiding water accumulation and affecting the quality of the unit. That is, the adjustment component of the water seal device of this embodiment can adjust the height of the other end of the drainage component based on the change of the operating pressure of the air conditioner unit, so that the water seal device of this embodiment can widely adapt to the water seal pressure differences of different negative pressure units, and solves the technical problem that the drainage water pressure of the water seal device in the prior art cannot be automatically adjusted with the change of the operating pressure of the air conditioner unit.

[0031] According to a preferred embodiment, the water seal device further includes a bracket assembly for fixing the drainage assembly and the adjustment assembly. Preferably, the bracket assembly includes a first bracket 301 and a second bracket 302, and the first bracket 301 and the second bracket 302 are spaced apart from each other, as Figure 2 shown. The preferred technical solution of this embodiment solves the installation and fixing problems of the drainage assembly and the adjustment assembly through the bracket assembly, and can improve the reliability of the water seal device.

[0032] According to a preferred embodiment, the drainage assembly includes a first water pipe 101 and a second water pipe 102, as Figure 2 shown. Preferably, the first water pipe 101 is located on the side close to the drainage outlet of the air conditioner unit, and the second water pipe 102 is located on the side far from the drainage outlet of the air conditioner unit. More preferably, the second water pipe 102 is a telescopic flexible water pipe, and the adjustment assembly adjusts the height difference between the two ends of the drainage assembly by adjusting the telescopic length of the second water pipe 102. More preferably, the first water pipe 101 and the second water pipe 102 can be fixedly connected by an elbow. Specifically, when the negative pressure inside the air conditioner unit increases, the length of the second water pipe 102 is extended by the action of the adjustment assembly, so that the height of the other end of the drainage assembly is reduced, and the height difference between the two ends of the drainage assembly increases; when the negative pressure inside the air conditioner unit decreases, the length of the second water pipe 102 is shortened by the action of the adjustment assembly, so that the height of the other end of the drainage assembly is increased, and the height difference between the two ends of the drainage assembly decreases.

[0033] According to a preferred embodiment, one end of the first water pipe 101 is connected to the drainage outlet of the air conditioner unit, and the other end of the first water pipe 101 communicates with one end of the second water pipe 102 and is fixed on the first bracket 301; the other end of the second water pipe 102 is fixed on the second bracket 302. Preferably, the other end of the first water pipe 101 and one end of the second water pipe 102 are fixed on the first bracket 301 by a bolt fastener; the other end of the second water pipe 102 is fixed on the second bracket 302 by a bolt fastener. The first water pipe 101 and the second water pipe 102 of the preferred technical solution of this embodiment are fixed on the first bracket 301 and the second bracket 302 by bolt fasteners, which can improve the stability of the drainage assembly.

[0034] According to a preferred embodiment, the adjustment assembly includes an electromagnetic part located at both ends of the second water pipe 102, and the adjustment assembly adjusts the telescopic length of the second water pipe 102 by adjusting the adsorption force of the electromagnetic part. Preferably, the electromagnetic part includes a magnet 201 and a coil 202, as Figure 2As shown in the figure. Among them, the magnet 201 and the coil 202 are respectively fixed on the first bracket 301 and the second bracket 302. The coil 202 is also connected to an electromagnetic relay, and the adjusting assembly adjusts the adsorption force between the magnet 201 and the coil 202 by adjusting the current intensity of the electromagnetic relay. The electromagnetic relay is a device in the prior art and will not be elaborated here. The preferred technical solution of this embodiment can adjust the current of the electromagnetic relay based on the change of the operating pressure in the air-conditioning unit, and adjust the adsorption force between the magnet 201 and the coil 202 brackets through the change of the electromagnetic relay current, so as to adjust the telescopic length of the second water pipe 102, and further realize the adjustment of the height difference between the two ends of the drainage assembly. In the preferred technical solution of this embodiment, the magnet 201 and the coil 202 are respectively fixed on the first bracket 301 and the second bracket 302, which can achieve the advantages of firm and reliable installation and not being easily disassembled during daily use.

[0035] According to a preferred embodiment, the adjusting assembly further includes a spring 203. The spring 203 is sleeved outside the second water pipe 102, and both ends of the spring 203 are respectively fixed on the first bracket 301 and the second bracket 302, as Figure 2 shown. Preferably, the spring 203 and the second water pipe 102 have the same telescopic amount. The adjusting assembly of the preferred technical solution of this embodiment further includes a spring 203. When the negative pressure in the air-conditioning unit increases during operation and the length of the second water pipe 102 extends, the spring 203 is also in an extended state; when the negative pressure in the air-conditioning unit decreases during operation and the length of the second water pipe 102 needs to be shortened, the spring 203 can drive the second water pipe 102 to contract through its reset function, so as to shorten the length of the second water pipe 102.

[0036] According to a preferred embodiment, the adjusting assembly further includes a pressure sensor and a controller. Among them, the pressure sensor is connected to the controller, and the pressure sensor is used to detect the operating pressure of the air-conditioning unit and send the detection result to the controller; the controller is also connected to the electromagnetic relay, and the controller adjusts the current intensity of the electromagnetic relay based on the operating pressure of the air-conditioning unit. Preferably, when the current intensity increases, the adsorption force between the magnet 201 and the coil 202 increases, the lengths of the second water pipe 102 and the spring 203 shorten, and the height difference between the two ends of the drainage assembly decreases; when the current intensity decreases, the adsorption force between the magnet 201 and the coil 202 weakens, the lengths of the second water pipe 102 and the spring 203 extend, and the height difference between the two ends of the drainage assembly increases.

[0037] Preferably, the controller calculates the telescopic length of the second water pipe 102 based on the following formula: P + ρgΔh ≥ P1, where P is the negative pressure inside the air conditioner unit; P1 is the atmospheric pressure, and Δh is the telescopic length of the second water pipe 102. Further, the controller can also adjust the input current intensity according to the telescopic length Δh of the second water pipe 102. That is, the adjustment component in this embodiment detects the operating pressure of the air conditioner unit and adjusts the telescopic length of the second water pipe 102 to satisfy P + ρgΔh ≥ P1, thereby discharging the condensed water in the water receiving tray of the air conditioner unit.

[0038] Since the second water pipe 102 and the spring 203 have the same telescopic length, Δh can be said to be either the telescopic length of the second water pipe 102 or the telescopic length of the spring 203. Before the second water pipe 102 and the spring 203 act, the controller adjusts the input current intensity based on the detected operating pressure of the air conditioner unit, thereby adjusting the adsorption force between the magnet 201 and the coil 202, and further adjusting the telescopic lengths of the second water pipe 102 and the spring 203.

[0039] Specifically, when the air conditioner unit is not powered on, the negative pressure inside the air conditioner unit is 0, and the telescopic amount Δh = 0. After the unit is powered on, after the measured value of the pressure sensor stabilizes for 60 s, the output pressure value P is obtained. According to the formula P + ρgΔh > P1, the height of the second water pipe 102 that needs to be adjusted is calculated, and then the input current intensity I that needs to be adjusted is adjusted based on the telescopic lengths of the second water pipe 102 and the spring 203 and the magnitude of the adsorption force between the magnet 201 and the coil 202. After the unit is powered off, the negative pressure P inside the unit = 0, P + ρgΔh < P1, the current intensity slowly weakens to 0 within 120 s, and the telescopic amount Δh = 0.

[0040] The water seal device in this embodiment can not only adapt to the change of the operating pressure inside the air conditioner unit, avoid water accumulation inside the air conditioner unit, but also achieve engineering scale and reduce costs.
