A type of air cooler

Abstract

This utility model relates to a refrigeration device, particularly a cold air blower, comprising a housing, a water collection tray and a mounting bracket inside the housing, a drain hole at the bottom of the water collection tray, a telescopic corrugated pipe fixedly connected to the upper end of the drain hole, and a support ring fixedly connected to the upper end of the telescopic corrugated pipe, and a motor for driving the support ring to move up and down on the mounting bracket. By setting up the motor and the telescopic corrugated pipe, the position of the drain outlet can be adjusted by controlling the vertical extension and contraction length of the corrugated pipe using the motor. When the water in the water collection tray submerges the corrugated pipe, it will automatically overflow through the telescopic corrugated pipe. When automatic drainage is required, the length of the telescopic corrugated pipe is reduced so that the upper end of the corrugated pipe is submerged in the water, allowing water to be discharged through the corrugated pipe. At the same time, the overflow water level can be adjusted by controlling the length of the telescopic corrugated pipe without the need for a water level sensor, thus reducing the risk of leakage.

Description

Technical Field

[0001] This utility model relates to a refrigeration device, and more particularly to a cold air blower. Background Technology

[0002] Evaporative air coolers, also known as eco-friendly air conditioners, work by cooling the surrounding air with their internal heat exchange components. This cooling process produces a large amount of condensate, which falls into a collection pan. For evaporative air coolers using water-spraying packing components, the condensate can be used as spray water for the packing. However, as the amount of water in the collection pan increases, it needs to be drained periodically to prevent water from overflowing and causing leaks.

[0003] Traditional evaporative air coolers drain water by installing a drain valve at the bottom of the water collection pan. Currently, there are also evaporative air coolers on the market that drain water by installing a drain pump. However, both drain valves and drain pumps require active control to drain water and cannot achieve automatic overflow when the water is full. If the water level sensor malfunctions, there is still a risk of water leakage.

[0004] In view of this, the applicant conducted an in-depth study on the drainage structure of the evaporative cooler, which led to this case. Utility Model Content

[0005] The purpose of this invention is to provide a cooler with a relatively low risk of water leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cool air blower includes a housing, a water collection tray and a mounting bracket fixedly arranged opposite to the water collection tray inside the housing, a vertically arranged drain hole at the bottom of the water collection tray, a telescopic corrugated pipe communicating with the drain hole fixedly connected to the upper end of the drain hole, a support ring fixedly connected to the upper end of the telescopic corrugated pipe, and a motor for driving the support ring to move up and down on the mounting bracket.

[0008] As an improvement of this utility model, a sinkhole is provided on the water collection plate, and the drain hole is provided at the bottom of the sinkhole and arranged coaxially with the sinkhole. The lower end of the telescopic corrugated pipe is fixedly connected to the bottom of the sinkhole. After the telescopic corrugated pipe is compressed to its minimum length, the sum of the length of the telescopic corrugated pipe and the thickness of the support ring is less than the depth of the sinkhole.

[0009] As an improvement of this utility model, the mounting bracket is fixedly connected to the water collection tray or the housing.

[0010] As an improvement of this utility model, the motor is a push rod motor, and the push rod of the push rod motor is arranged vertically and fixedly connected to the support ring.

[0011] As an improvement of this utility model, the motor is a rotary motor, the output shaft of the rotary motor is arranged vertically, and a screw arranged coaxially with the output shaft of the rotary motor is fixedly connected to the output shaft of the rotary motor. The screw is helically connected to the support ring, and the mounting bracket is also provided with a guide rod that is vertically slidably connected to the support ring.

[0012] As an improvement of this utility model, a water spraying packing assembly is also provided inside the housing, located directly above the water collection tray. A water pump is provided inside the water collection tray, and a return water pipe is connected to the outlet of the water pump. A spraying assembly is connected to the end of the return water pipe away from the water pump. The return water pipe has a vertically arranged telescopic pipe section.

[0013] As an improvement of this utility model, the housing has an air inlet and an air outlet, and a water finned tube heat exchange assembly is also provided inside the housing. The water finned tube heat exchange assembly and the water spraying packing assembly are arranged sequentially from the air inlet to the air outlet. A water inlet pipe is connected between the water inlet of the water finned tube heat exchange assembly and the water outlet of the water pump, and a water outlet pipe is connected between the water outlet of the water finned tube heat exchange assembly and the water collection tray.

[0014] As an improvement of this utility model, a filter plate is provided on the air inlet.

[0015] By adopting the above solution, this utility model has the following beneficial effects:

[0016] By setting up a motor and a telescopic corrugated pipe, the motor controls the vertical extension and retraction of the corrugated pipe, thereby adjusting the position of the drain outlet. When the water in the collection pan submerges the corrugated pipe, it will automatically overflow through the telescopic corrugated pipe. When automatic drainage is required, the length of the telescopic corrugated pipe is reduced so that the upper end of the corrugated pipe is submerged in the water, allowing water to be discharged through the corrugated pipe. At the same time, the overflow water level can be adjusted by controlling the length of the telescopic corrugated pipe, without the need for a water level sensor, thus reducing the risk of leakage.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-2 As shown, the air cooler provided in this embodiment includes a housing 10, inside which a water collection tray 20 and a mounting bracket 30 are fixedly arranged relative to the water collection tray 20. That is to say, the relative positions of the water collection tray 20 and the mounting bracket 30 are constant. In this embodiment, the mounting bracket 30 is fixedly connected to the water collection tray 20. Of course, the mounting bracket 30 can also be fixedly connected to the housing 10 or the support frame of the water spraying filler assembly 50 mentioned below.

[0033] The casing 10 has an air inlet on one side and an air outlet on the other side. The structure and specific location of the air inlet and outlet are the same as those of existing evaporative air coolers. Inside the casing 10, there is also a water-finned tube heat exchange assembly 40 and a water-spraying packing assembly 50 located directly above the water collection tray 20. The water-finned tube heat exchange assembly 40 and the water-spraying packing assembly 50 are arranged sequentially from the air inlet to the air outlet. The structures of the water-finned tube heat exchange assembly 40 and the water-spraying packing assembly 50 are the same as those used in existing evaporative air coolers and can be purchased commercially. They are not the focus of this embodiment and will not be described in detail here. It should be noted that when the cooling demand of the evaporative air cooler is small, the water-finned tube heat exchange assembly 40 may not be installed.

[0034] A water pump 60 is installed inside the water collection tray 20. The outlet of the water pump 60 is connected to a return water pipe 61. The end of the return water pipe 61 furthest from the water pump 60 is connected to a spray assembly 70. The water pump 60 and spray assembly 70 are also readily available commercial components and will not be described in detail here. An inlet water pipe 41 connects the inlet of the water finned tube heat exchanger 40 to the outlet of the water pump 60, and an outlet water pipe 42 connects the outlet of the water finned tube heat exchanger 40 to the water collection tray 20. Furthermore, both the return water pipe 61 and the inlet water pipe 41 are equipped with on / off valves 80 at the ends connected to the water pump 60 to control the on / off state of the corresponding pipes.

[0035] Preferably, in this embodiment, the return water pipe 61 has a vertically arranged telescopic pipe section 62. The telescopic pipe section 62 can be a telescopic water pipe that can be purchased directly from the market. This makes it easy to adjust the height position of the spray assembly 70 according to actual needs during assembly without replacing the return water pipe 61, which helps to improve assembly efficiency and reduce the accuracy requirements for the length of the return water pipe 61.

[0036] Preferably, in this embodiment, a filter plate 11 is provided on the air inlet of the housing 10.

[0037] The bottom of the water collection tray 20 is provided with vertically arranged drain holes 21. The upper end of the drain hole 21 is fixedly connected to a telescopic corrugated pipe 22 that communicates with the drain hole 21, and the lower end is integrally connected to a threaded connecting pipe 23. The threaded connecting pipe 23 is used to connect an external drain pipe or an external water tank. The external drain pipe or external water tank is not part of the air cooler in this embodiment and needs to be configured separately during use.

[0038] A support ring 24 is fixedly connected to the upper end of the telescopic bellows 22. A motor 31 for driving the support ring 24 to move up and down is provided on the mounting bracket 30. The motor 31 can be a push rod motor, with the push rod of the push rod motor arranged vertically and fixedly connected to the support ring 31, thereby driving the support ring 24 to move up and down. In this embodiment, the motor 31 is a rotary motor, with the output shaft of the rotary motor arranged vertically, and a screw 32 arranged coaxially with it is fixedly connected to the output shaft of the rotary motor. The screw 32 is helically connected to the support ring 24 (a threaded hole for the screw 32 needs to be opened on the support ring 24). In addition, a guide rod 33 is also provided on the mounting bracket 30, which is vertically slidably connected to the support ring 24 (a through hole for the guide rod 33 needs to be opened on the support ring 24). In this way, the rotation of the screw 32 can drive the support ring 24 to move up and down along the guide rod 33, thereby adjusting the height position of the upper end of the telescopic bellows 22.

[0039] Preferably, in this embodiment, a countersunk hole 25 is provided on the water collection tray 20, and a drain hole 21 is provided at the bottom of the countersunk hole 25 and arranged coaxially with the countersunk hole 25. The lower end of the telescopic corrugated pipe 22 is fixedly connected to the bottom of the countersunk hole 25. After the telescopic corrugated pipe 22 is compressed to its minimum length, the sum of the length of the telescopic corrugated pipe 22 and the thickness of the support ring 24 is less than the depth of the countersunk hole 25. This makes it easier to drain the water in the water collection tray 20 as much as possible during maintenance or repair. Of course, since there is a gap between the side wall of the countersunk hole 25 and the outer wall of the telescopic corrugated pipe 22, water will accumulate in the gap. However, this water accumulation will not affect the maintenance and repair of the air cooler. If necessary, the water accumulation in the gap can also be emptied by disassembling the water collection tray 20.

[0040] When drainage is needed, the motor 31 drives the support ring 24 to slide down and embed into the countersunk hole 25, so that the water in the water collection tray 20 is discharged in sequence through the telescopic corrugated pipe 22, the drain hole 21 and the threaded connecting pipe 23. During normal use, the motor 31 drives the support ring 24 to move to the predetermined position (the horizontal position of this position is lower than the horizontal position of the upper end of the water collection tray 20) according to actual needs. When the water surface in the water collection tray 20 submerges the support ring 24, it will flow out from the telescopic corrugated pipe 22 to achieve overflow, effectively preventing water leakage inside the air cooler.

[0041] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
