Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the attached figures 1-3, the dance room with adjustable temperature and humidity comprises a room main body 1, wherein the main body 1 comprises side plates 2 which are enclosed into a columnar structure and a heat conduction plate 3 connected to the lower ends of the side plates 2, a cavity 4 is formed in the heat conduction plate 3, and a heat exchange device 5 is arranged in the cavity 4 and used for adjusting the temperature and humidity in the main body 1; the heat exchange device 5 penetrates through the side plate 2 and extends to the outside of the main body 1; the inside of main part 1 is equipped with a plurality of warm and humid acidimeters 6 that connect in parallel electricity on the direction of height, and warm and humid acidimeters 6 electricity connection controller 7, a humidifier 8 is connected to controller 7 electricity, and humidifier 8 is located main part 1 and is close to the upper end position.
This device is through setting up main part 1 into columnar structure to avoid appearing the corner shape, thereby solved the air current in main part 1 inside because the problem that the interior temperature inequality of main part 1 that local vortex leads to influences dancer's comfort level. Then, in order to achieve uniform heat exchange, the heat conducting plate 3 is arranged at the lower part of the main body 1, and the heat exchange device 5 is arranged in the heat conducting plate 3, so that the function of adjusting the temperature in the room in a convection-heat conduction-convection mode is realized. According to the inverse proportion relation of temperature and humidity, when the temperature is low in the main body 1, the indoor humidity can correspondingly rise, and the comfort level of people can be influenced when the temperature is low, so that the plurality of thermo-hygrometers 6 are arranged in the height direction of the main body 1, and the temperature and the humidity in the main body 1 can be measured timely. When the user feels heat in the main body 1 and makes the heat exchange device 5 heat supply for a period of time so that the indoor humidity is reduced, the humidifier 8 which is automatically opened can be used for improving the indoor humidity, and the purpose of improving the indoor temperature and humidity is achieved.
The heat exchanging device 5 comprises a heat exchanging coil 51 positioned inside the heat conducting plate 3 for adjusting the temperature inside the main body 1 through the heat conducting plate 3; the heat exchanging device 5 further comprises a heat pump 52 for transporting heat into the heat conducting plate 3 through a heat exchanging coil 51.
In the setting process, the condensation end of the heat pump 52 is arranged in the heat conduction plate 3, so that the purpose of heating the inside of the main body 1 is achieved by utilizing the heat release of the condensation end of the heat pump 52 in the operation process. The specific working principle is as follows: when the heat pump 52 works, heat is released from the condensation end, and then the heat is released from the interior of the heat conducting plate 3 to the upper part, and the purpose of heating the indoor is achieved according to the characteristic that hot air flows upwards. In this process, since the heat conductive plate 3 is a material which is easily heat conductive, the heat released from the heat pump 52 can be released from the heat conductive plate 3 into the main body 1 by heat conduction.
The heat pump 52 is provided outside the main body 1, and a protective cover that can be opened is provided outside the heat pump 52.
Since the heat pump 52 is a device including a compressor, a condenser, a throttle valve, an evaporator, and the like in the prior art, and the compressor is the core of the heat pump, in order to reduce the influence of different outdoor weather conditions, a protective cover is provided, so as to achieve the purpose of reducing the maintenance frequency of the device and further prolonging the service life of the device.
The hygrothermograph 6 is embedded in the main body 1, and a display screen for displaying temperature and humidity is arranged on the hygrothermograph 6.
When setting up hygrothermograph 6 on main part 1, adopt and inlay the mode of establishing in main part 1 with it to can prevent that the problem that hygrothermograph 6 appears in being located main part 1 is being met to the in-process mistake that the dancer took exercise at carrying out the dance. The purpose of facilitating the reading of the temperature and humidity in the main body 1 can be achieved by using the hygrothermograph 6 with a display screen.
The humidifier 8 is connected with a water delivery pipe which is used for delivering water to the humidifier 8 in time, and the water delivery pipe penetrates through the side plate 2 of the main body 1 and is communicated with a water source.
