Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of central air-conditioning, in particular to a positive and negative pressure universal automatic energy-saving drainage and anti-fouling valve and an air-conditioner. Background Art
[0002] Traditional air conditioning drainage uses a U-shaped water seal drainage device. This structure has the following problems or disadvantages:
[0003] 1: When the air conditioner is stopped or in a windless state, the inside of the cabinet is in a pressure-free state, and the U-shaped water seal drainage device is in a state of internal and external communication. External dirt, flying insects, and dirty air enter the unit through the pipes, causing internal pollution of the unit or pipe blockage;
[0004] 2: If the unit is a positive pressure unit and there is no condensate in the water pan, the U-shaped water seal drainage device is in a state of internal and external communication. The air treated by the unit will leak to the outside of the unit due to the positive pressure, causing energy loss of the unit;
[0005] 3: If the unit is a negative pressure unit and there is no condensed water in the water pan, the U-shaped water seal drainage device is connected inside and outside. External dirt, flying insects, and dirty air are sucked into the unit due to the negative pressure, causing internal air pollution and energy loss. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] See also Figure 1 and 2 The utility model provides a positive and negative pressure universal automatic energy-saving drainage and anti-fouling valve, comprising a condensate pipe 1, the condensate pipe 1 is connected to one end of a condensate riser 2, the other end of the condensate riser 2 is connected to a condensate pipe 3, and the condensate pipe 3 is provided with a valve body assembly for automatically opening and closing the pipeline;
[0024] The condensate pipe 1 is connected to the condensate riser 2 at a 90-degree angle, and the condensate riser 2 is connected to the condensate pipe 3 at a 90-degree angle.
[0025] Specifically, the valve body assembly includes a float cavity 4 , which is a spherical hollow structure. A float 5 is provided in the float cavity 4 , and a valve plate 6 is provided on the float 5 .
[0026] Specifically, an exhaust hole 7 is provided on the top of the float cavity 4 .
[0027] Specifically, the float 5 is a spherical hollow structure.
[0028] This valve can be used in both positive and negative pressure box units; it can achieve automatic drainage and closing under positive and negative pressure boxes without power supply; it can achieve drainage with water and closing without water under positive and negative pressure boxes, preventing dirt from entering, air leakage or energy loss.
[0029] This embodiment solves the drainage problem in the box under three states: no pressure, negative pressure, and positive pressure. The valve can automatically drain water according to whether there is water inside the box or not. It drains water when there is water and closes when there is no water, preventing dirt from entering and preventing air leakage or energy loss.
[0030] It should be noted that the positive and negative pressure universal automatic energy-saving drainage and anti-pollution valve described in this embodiment can be used on any equipment with drainage and anti-pollution requirements, and is not limited to its application in air-conditioning equipment described below.
[0031] The utility model also provides an air conditioner, including a sealed and insulated box body 8, in which a condensate tray 9 is arranged, and also includes the above-mentioned positive and negative pressure universal automatic energy-saving drainage and anti-fouling valve, and the condensate tray 9 is connected to the condensate pipe 1 through a water tray outlet pipe 10.
[0032] Taking this application as an example, the specific drainage solution of the positive and negative pressure universal automatic energy-saving drainage and anti-fouling valve in the air conditioner is as follows:
[0033] See also Figure 3 , pressure-free drainage solution: the air pressure inside the box is the same as the air pressure outside the box.
[0034] The box is in a pressure-free state, and there is water in the condensate pan 9. The condensate flows into the condensate riser 2 through the condensate pipe 1. When the condensate in the condensate riser 2 reaches a certain height, the buoyancy of the condensate is greater than the gravity of the float 5. The float 5 and the valve plate 6 move upward, and the condensate pipe 3 opens to achieve drainage. When the buoyancy of the condensate is less than the gravity of the float 5, the float 5 and the valve plate 6 fall, the condensate pipe 3 is blocked, and drainage stops.
[0035] When the box is in a non-pressurized state, the water pan is empty or the machine is shut down, the float 5 drops due to its own gravity, and the valve plate 6 cuts off the condensate pipe 3, thus saving energy and preventing pollution.
[0036] See also Figure 4 , negative pressure drainage solution, the air pressure inside the box is lower than the air pressure outside the box.
[0037] When the box is under negative pressure, there is water in the condensate pan 9, and the condensate flows into the condensate riser 2 through the condensate pipe 1. When the condensate in the condensate riser 2 reaches a certain height, the buoyancy of the condensate is greater than the gravity of the float 5 + the negative air pressure difference, the float 5 and the valve plate 6 move upward, the condensate pipe 3 opens, and drainage is achieved. When the buoyancy of the condensate is less than the gravity of the float 5 + the negative air pressure difference, the float 5 and the valve plate 6 descend, the condensate pipe is blocked, and drainage stops.
[0038] In the negative pressure state inside the box, the water pan is empty or the machine is shut down: the float 5 drops due to its own gravity and the negative pressure difference of the air, and the valve plate 6 cuts off the condensate pipe 3, saving energy and preventing pollution.
[0039] See also Figure 5 , positive pressure drainage solution, the air pressure inside the box is greater than the air pressure outside the box.
[0040] When the box is under positive pressure, there is water in the condensate pan 9, and the condensate flows into the condensate riser 2 through the condensate pipe 1. When the condensate in the condensate riser 2 reaches a certain height, the buoyancy of the condensate + the positive air pressure difference is greater than the gravity of the float 5, the float 5 and the valve plate 6 move upward, the condensate pipe 3 opens, and drainage is achieved. When the buoyancy of the condensate + the positive air pressure difference is less than the gravity of the float 5, the float 5 and the valve plate 6 descend, the condensate pipe 3 is blocked, and drainage stops.
[0041] The box is in a positive pressure state, the water pan is empty or the machine is shut down: the positive air pressure difference is less than the weight of the float 5, the float 5 drops, and the valve plate 5 cuts off the condensate pipe 3, saving energy and preventing pollution.
