Description

Technical Field

[0001] The present invention relates to the technical field of air cooler equipment, and in particular to a system for detecting and protecting gas leaks in air coolers. Background Art

[0002] Cooling fan is a fan installed in the kitchen integrated ceiling. It is kept on the same plane as the ceiling and supplies air through the rotation of the reverse wind louvers to provide cool air for the kitchen and alleviate the high temperature environment during cooking. Cooling fan is usually installed in the kitchen integrated ceiling, usually above the head of the person standing to cook, or above the range hood and stove. Some cooler equipment also includes an exhaust fan. When the kitchen is heavy with smoke and the range hood cannot exhaust the kitchen smoke in time, the exhaust fan can be started to exhaust the dirty air containing smoke in the kitchen to the outside.

[0003] The advantages of a fan cooler include: it is installed in the ceiling and does not occupy the kitchen floor space; the fan cooler can effectively provide local cool air and is suitable for use in kitchens under high temperature environments; compared with air conditioners, the power consumption of the fan cooler is lower. The disadvantages of a fan cooler include: the air blown by the fan cooler is internally circulated, which may blow out hot air and has a limited cooling range; in addition, when a gas leak occurs in the kitchen, the fan cooler's exhaust fan cannot be started in time to discharge the leaked gas in the kitchen, which is prone to safety accidents.

[0004] Therefore, there is an urgent need for a system for detecting and protecting gas leaks in air conditioners. Summary of the invention

[0005] The purpose of the present invention is to provide a system for detecting and protecting gas leaks in a kitchen air conditioner, aiming to improve the problem in the related art that the exhaust fan of the kitchen air conditioner cannot be started in time to discharge the leaked gas in the kitchen.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A system for detecting and protecting a gas leak in a heat exchanger comprises a heat exchanger device, wherein the heat exchanger device comprises a blowing fan and an exhaust fan, and further comprises a methane sensor and an electric control board, wherein the methane sensor and the exhaust fan are electrically connected to the electric control board.

[0008] Furthermore, a carbon monoxide sensor is included, and the carbon monoxide sensor is electrically connected to the electric control board.

[0009] Furthermore, two blowing fans are provided.

[0010] Furthermore, the two blowing fans are electrically connected to the electric control board.

[0011] Furthermore, the electric control board is electrically connected to a communication device.

[0012] Furthermore, the methane sensor and the carbon monoxide sensor are both electrically connected to an audible and visual alarm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When a natural gas leak occurs in the kitchen, the natural gas content in the kitchen increases. The main component of natural gas is methane, that is, the methane concentration in the kitchen will increase. The methane sensor can monitor the changes in the methane concentration in the kitchen in time. When the methane concentration in the kitchen exceeds the preset standard value, the methane sensor transmits a signal to the electronic control board, and the electronic control board controls the start of the exhaust fan. The exhaust fan can discharge the air in the kitchen to the outdoors, which is conducive to timely reducing the methane concentration in the kitchen and reducing safety accidents caused by high methane concentration in the kitchen.

[0019] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] A system for detecting and protecting gas leaks in a cooler, referring to Figure 1 , including a cooler device, the cooler device includes a blowing fan 1 and an exhaust fan 2, and also includes a methane sensor 3 and an electric control board 4, and the methane sensor 3 and the exhaust fan 2 are electrically connected to the electric control board 4.

[0022] In this solution, when a natural gas leak occurs in the kitchen, the natural gas content in the kitchen increases. The main component of natural gas is methane, that is, the methane concentration in the kitchen will increase. The methane sensor 3 can monitor the concentration change of methane in the kitchen in time. When the methane concentration value in the kitchen exceeds the preset standard value, the methane sensor 3 transmits a signal to the electric control board 4, and the electric control board 4 controls the exhaust fan 2 to start. The exhaust fan 2 can discharge the air in the kitchen to the outdoors, which is conducive to timely reducing the methane concentration in the kitchen and reducing safety accidents caused by high methane concentration in the kitchen. The electric control board 4 and the exhaust fan 2 can be controlled and connected through switch elements such as relays and contactors. The above-mentioned electrical connection method belongs to the common knowledge known to those skilled in the art, and will not be repeated in this embodiment.

[0023] Furthermore, the methane sensor 3 is electrically connected to a sound and light alarm. The methane sensor 3 and the sound and light alarm can adopt an integrated methane detection alarm product on the market. When the methane sensor 3 detects that the methane concentration in the kitchen is too high, the corresponding sound and light alarm will send out a sound and light alarm signal, which is convenient for users to promptly discover the dangerous alarm signal of the kitchen.

[0024] Example 2

[0025] Based on Example 1, in this example, reference Figure 1 The system for detecting and protecting gas leaks in the air conditioner also includes a carbon monoxide sensor 5, which is electrically connected to the electric control board 4. Some families use coal gas, and the main component of the coal gas is carbon monoxide. In this case, the carbon monoxide sensor 5 can monitor the carbon monoxide concentration in the kitchen in time. When a gas leak occurs in the kitchen, the carbon monoxide concentration increases with the increase in the amount of gas leakage. When the carbon monoxide sensor 5 detects that the carbon monoxide concentration is higher than the preset standard value, the carbon monoxide sensor 5 transmits a signal to the electric control board 4, and the electric control board 4 controls the exhaust fan 2 to start. The exhaust fan 2 can discharge the carbon monoxide in the kitchen to the outdoors, which is beneficial to reducing the concentration of carbon monoxide in the kitchen, and thus helps to reduce the occurrence of safety accidents.

[0026] Example 3

[0027] Based on Example 1, in this example, reference Figure 1The cooler device includes two blowing fans 1, and the two blowing fans 1 are electrically connected to the electric control board 4. When the cooler device is used daily, the two blowing fans 1 can enhance the cooling effect on the high-temperature area of ​​the kitchen; and when the methane sensor 3 detects that the methane concentration in the kitchen exceeds the preset standard value, the electric control board 4 can control the two blowing fans 1 to turn on. Even if the cooler device is not needed at present, the two blowing fans 1 blow the air in the kitchen. On the one hand, by stirring the air in the kitchen, a part of the air containing methane in the kitchen can be blown out of the window to reduce the methane concentration in the kitchen. On the other hand, the methane in the internal area of ​​the kitchen can be blown to other areas of the room to reduce the methane concentration in the kitchen area, which can reduce the adverse effects of methane on people in the kitchen to a certain extent.

[0028] Example 4

[0029] Based on Example 1, in this example, reference Figure 1 The electric control board 4 is electrically connected to a communication device, and the communication device includes a communication module 6. The communication module 6 can adopt wireless communication. The methane concentration data monitored by the methane sensor 3 can be transmitted to the background monitoring host through the communication module 6. The background monitoring personnel will notify the home user to shut down the gas source, and then the maintenance personnel will perform maintenance.

[0030] Example 5

[0031] Based on Example 2, in this example, refer to Figure 1 The methane sensor 3 and the carbon monoxide sensor 5 are both electrically connected to an audible and visual alarm. An audible and visual alarm (also called an audible and visual alarm) is an alarm signal device used in dangerous places to send warning signals to people through sound and various lights; the methane sensor 3 can also be integrated with its corresponding audible and visual alarm, that is, the methane detection alarm is directly used; the carbon monoxide sensor 5 can also be integrated with its corresponding audible and visual alarm, that is, the carbon monoxide detection alarm is directly used.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
