Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a gas dryer. Background Art

[0002] The principle of the currently common gas clothes dryer in the market is to use the combustion of gas to generate high-temperature flue gas, and under the action of a fan, the high-temperature flue gas dries wet clothes. Generally, a gas valve is adopted, and a flue gas thermostat is arranged in the combustion chamber. When the temperature rises to the threshold value, the controller closes the gas valve and the burner stops burning. When the temperature drops to the starting value, the controller controls the gas valve to open and continues to burn. Although this can control the maximum temperature and prevent the temperature from being too high, the temperature rises and falls, making it difficult to form a continuous and stable temperature, and the drying efficiency is low. Moreover, only a flue gas thermostat is arranged in the combustion chamber, and only the temperature of the combustion chamber can be detected, and the actual temperature in the clothes drying barrel cannot be detected. When the flue gas thermostat fails, the temperature cannot be effectively controlled, and the reliability and accuracy are not high. Summary of the Utility Model

[0018] Referring to Figure 1 , a gas dryer of the present utility model includes a controller 11, a gas proportional valve 12, a burner 13, a combustion chamber 14, a blower 15, and a drying drum 16. The gas proportional valve 12 is arranged on the gas pipe, the gas pipe is connected to the burner 13, the combustion chamber 14 is located between the burner 13 and the blower 15, the air outlet end of the blower 15 is communicated with the drying drum 16, a temperature sensor 20 is arranged in the drying drum 16, the controller 11 is electrically connected to the temperature sensor 20 and the gas proportional valve 12 respectively. The temperature sensor 20 detects the real-time temperature information in the drying drum 16 and feeds back the real-time temperature information to the controller 11. The controller 11 can control the opening degree of the gas proportional valve 12 according to the real-time temperature information, so as to control the fire power size and keep the temperature in the drying drum 16 stable. Since the gas proportional valve 12 is adopted, the controller 11 can adjust the opening degree of the gas proportional valve 12 in real time according to the real-time temperature information detected by the temperature sensor 20, control the fire power size, so that the real-time temperature in the drying drum 16 is maintained within a small temperature range, avoid large temperature differences, keep drying without interruption, and achieve rapid drying.

The limit thermostat 21 and the temperature sensor 20 act together without interfering with each other. When the temperature sensor 20 fails, the limit thermostat 21 plays a role of backup protection, that is, when the temperature in the drum rises to the maximum value, the controller 11 closes the gas valve and the burner 13 stops burning. When the temperature in the drum drops to the starting value, the gas valve opens and continues to burn.

[0020] Furthermore, a flue temperature controller 22 for limiting the maximum temperature in the combustion chamber 14 is provided in the combustion chamber 14. The controller 11 is electrically connected to the flue temperature controller 22. When the temperature in the combustion chamber 14 rises to the limit value of the flue temperature controller 22, the controller 11 cuts off the gas proportional valve 12 to prevent unsmooth smoke exhaust.
