[0017] The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings.

[0018] Example:

[0019] The specific embodiment of the constant temperature heating drying room of the utility model is shown in the accompanying drawings. Figure 1It mainly includes a heating water tank 1. The upper left end of the heating water tank 1 is connected to a water inlet pipe 101, and the lower front end is connected to a water discharge pipe 102. Water can be replenished through the water inlet pipe 101 and drained through the water discharge pipe 102. A plurality of heating pipes 106 are provided in the heating water tank 1 for quickly heating water. A temperature probe 105 is connected to the lower front end of the heating water tank 1. The temperature probe 105 is located above the water discharge pipe 102 and is used to detect the water temperature and control the heating pipe 106 to start or stop heating, so that the water temperature is maintained within a certain range. The lower left end of the heating water tank 1 is connected to a hot water outlet pipe 103, and the top is connected to a hot water return pipe 104. Hot water is output through the hot water outlet pipe 103 and returned to the heating water tank 1 through the hot water return pipe 104 for circulation and heating.

[0020] The hot water outlet pipe 103 is equipped with a main hot water switch 107, a water pump 108, and a flow control valve 109. The main hot water switch 107 controls the flow of hot water, the water pump 108 circulates water, and the flow control valve 109 controls the flow rate of hot water. The hot water outlet pipe 103 and the hot water return pipe 104 are each connected to the heat exchanger 2. Hot water is introduced into the heat exchanger 2 as a heat exchange medium. After heat exchange, the hot water returns to the heating water tank 1 for heating and then continues to circulate back to the heat exchanger 2 for use.

[0021] A fresh air inlet pipe 201 is connected to the top of the heat exchanger 2, which is used to allow fresh air to enter and heat it. The left and right sides of the heat exchanger 2 are respectively connected to a first ventilation pipe 202 and a second ventilation pipe 203. The first ventilation pipe 202 and the second ventilation pipe 203 are respectively connected to the drying room body 4, and are used to pass the heated fresh air into the drying room body 4 for circulating blowing.

[0022] Specifically, the drying room body 4 includes four side wall panels, a bottom panel and a top panel connected to the four side wall panels. The left and right side wall panels are evenly distributed with a number of hot air return vents 401 for circulating air. The first ventilation duct 202 is connected to the left wall panel of the drying room body 4 through the circulation fan 3, and the second ventilation duct 203 is connected to the right wall panel of the drying room body 4. When the circulation fan 3 blows in the forward direction, the air flow direction is as follows: Figure 1 As shown by the hollow arrow in the figure, the heated fresh air is blown out from the hot air outlet and return air port 401 on the left wall panel of the drying room body 4 through the first ventilation pipe 202, and then flows into the heat exchanger 2 from the hot air outlet and return air port 401 on the right wall panel to the second ventilation pipe 203, thus realizing the automatic circulation of the left air supply in the room. When the circulation fan 3 blows in the reverse direction, the flow direction of the gas is as follows: Figure 1As shown by the dotted hollow arrows in the figure, the heated fresh air is blown out of the hot air outlet and return air vent 401 on the right wall panel of the drying room body 4 through the second ventilation duct 203. From the hot air outlet and return air vent 401 on the left wall panel, it is collected by the first ventilation duct 202 and circulated into the heat exchanger 2, thus realizing automatic right-side air circulation in the room. By setting the cycle time of the forward and reverse blowing, the temperature on both sides can be more evenly distributed, and the temperature throughout the drying room can also be more uniform.

[0023] Second temperature collection probes 403 are respectively provided at the four corners of the top wall panel of the drying room body 4. The four second temperature collection probes 403 are used to detect the temperature of the hot air outlet and return air outlet 401 on the left and right side wall panels. When the temperature at any point is too high, the blowing is stopped and the room temperature is allowed to wait for heating.

[0024] A first temperature probe 402 is located in the center of the top wall panel of the drying room body 4, and an exhaust fan 5 is also installed on the top wall panel. The first temperature probe 402 is used to detect the main temperature inside the drying room body 4. If the detected temperature is too high, the exhaust fan 5 automatically turns on to exhaust the high-temperature air, restoring the room temperature to normal.

[0025] A double door 404 is installed on the front wall of the drying room body 4 to facilitate people to enter and exit.

[0026] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included within the scope of protection of the present invention.
