Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1 to 6, an air duct system 100 of a drying apparatus according to an embodiment of the present invention includes a drying chamber 1, a heat supply air duct 2, a fan 3, and a variable frequency plate assembly 4.

The drying chamber 1 is provided with an air inlet and an air outlet, one end of the heat supply air duct 2 is communicated with the air inlet, the other end of the heat supply air duct 2 is communicated with the air outlet, and the fan 3 is arranged in the heat supply air duct 2 to drive air to flow. It can be understood that the drying chamber 1 can prevent the objects to be dried, the fan 3 can drive the air to circularly flow in the drying chamber 1 and the heat supply air duct 2, specifically, the air in the heat supply air duct 2 flows into the drying chamber 1 through the air inlet, and the air after moisture absorption flows into the heat supply air duct 2 through the air outlet.

Further, as shown in fig. 1-6, at least a portion of the inverter board assembly 4 is disposed in the heat supply air duct 2, and the inverter board assembly 4 is used for controlling the operation of the inverter compressor 7 of the drying apparatus. It can be understood that the operation of the inverter compressor 7 controlled by the inverter board assembly 4 generates heat, and the heat can be directly transferred to the heat supply air duct 2 through the part of the inverter board assembly 4 located in the heat supply air duct 2, so that the heat loss is reduced.

The inventor finds that the frequency conversion plate of the drying equipment in the related art is arranged outside the air duct, the fan needs to be separately arranged for heat dissipation of the frequency conversion plate, the equipment cost is increased, and heat is dissipated to the environment and is not utilized. And this application is through changing the position that sets up of converter panel subassembly, is about to the at least part of converter panel subassembly and stretches into the air feed passageway, can reduce the fan and set up quantity, makes the heat energy of effluvium directly absorbed by the air in the heat supply air flue simultaneously.

According to the air duct system of the drying equipment, at least part of the frequency conversion plate assembly is arranged in the heat supply air duct, so that heat generated by the frequency conversion plate assembly can be directly absorbed by air in the heat supply air duct, heat loss is reduced, drying efficiency is improved, the number of fans is reduced, and cost is saved.

Further, as shown in fig. 1-6, the duct system 100 of the drying apparatus further includes an evaporator 5, the evaporator 5 is disposed in the heat supplying air duct 2, and the portion of the variable frequency plate assembly 4 located in the heat supplying air duct 2 is located behind the evaporator 5 in the flowing direction of the air.

In other words, the air discharged from the drying chamber 1 into the heat supply duct 2 flows through the evaporator 5 and the inverter board assembly 4. It should be noted that after the air flows into the drying chamber 1, the air absorbs the water vapor of the object to be dried to form medium-temperature high-moisture-content air, the high-moisture-content air flows to the evaporator 5 to complete dehumidification, the low-temperature low-moisture-content air formed after dehumidification is heated by the frequency conversion board assembly 4, and the heated air continuously flows to the drying chamber 1 along the air duct to dry the object to be dried.

Further, as shown in fig. 1-6, the air duct system 100 of the drying apparatus further includes a condenser 6, the condenser 6 is disposed in the heat supply air duct 2, the condenser 6 is located behind the evaporator 5 in the air flowing direction, and the fan 3 is located behind the condenser 6 and the variable frequency board assembly 4 in the air flowing direction. From this, condenser 6 can further heat the air after 5 dehumidifications of evaporimeter cooling, and the heat that condenser 6 and converter board subassembly 4 produced can heat the air after the dehumidification cooling jointly promptly, guarantees that the air that gets into drying chamber 1 is the low humid air of high temperature, improves drying efficiency.

In addition, the fan 3 is positioned behind the condenser 6 and the frequency conversion board assembly 4 in the flowing direction of the air, so that the fan 3 can drive the air to circulate, meanwhile, the fan 3 cannot be placed in the air with high moisture content, and the internal elements of the fan 3 are prevented from being damaged.

Further, as shown in fig. 1, the portion of the inverter board assembly 4 located in the heat supply duct 2 is located between the condenser 6 and the evaporator 5 in the flow direction of the air. From this, when the empty air after 5 dehumidifies the cooling of evaporimeter was through frequency conversion board subassembly 4, frequency conversion board subassembly 4 can fully the heat transfer with the air, improves the radiating effect to frequency conversion board subassembly 4, guarantees the reliability of the operation of frequency conversion board subassembly 4.

In addition, the position where the portion of the inverter board assembly 4 located in the heat supply duct 2 is disposed is not limited to that shown in fig. 1, and for example, as shown in fig. 2, the portion of the inverter board assembly 4 located in the heat supply duct 2 is located behind the condenser 6 in the flow direction of the air. Under this kind of mode of arrangement, the air after 5 dehumidifies the cooling of evaporimeter flows through condenser 6 earlier to can make condenser 6 fully exchange heat with the air, be favorable to protecting compressor system and reduce compressor system power consumption. Specifically, the setting position of the inverter board assembly 4 may be determined according to actual requirements.

In some embodiments, as shown in fig. 3 and 6, the condenser 6 includes a first condenser 61 and a second condenser 62, and the portion of the variable frequency board assembly 4 located in the heat supply duct 2 is located between the first condenser 61 and the second condenser 62 in the flow direction of the air. From this, the air after 5 dehumidifies and cools down firstly heats along the direction of first condenser 61, inverter board subassembly 4 and second condenser 62 step by step, can avoid inverter compressor 7 to load too high, can guarantee inverter board subassembly 4's radiating efficiency again.

The air duct system 100 of the drying device with the two structural forms does not affect the arrangement of the frequency conversion board assembly 4.

In some embodiments, as shown in fig. 5, the size of the evaporator 5 in the width direction of the heat supply air duct 2 is smaller than the width size of the heat supply air duct 2. That is, a space is provided between the evaporator 5 and at least one side wall of the heat supply air duct 2, so that a part of the air flowing out of the drying chamber 1 can directly flow to the frequency conversion board assembly 4 or the condenser 6 along the space, and the air dehumidified and cooled by the evaporator 5 is mixed, so that the temperature and humidity of the air flowing through the evaporator 5 are moderate.

In some embodiments, the distance between the portion of the inverter board assembly 4 located within the wind tunnel and the condenser 6 is less than the distance between the portion of the inverter board assembly 4 located within the wind tunnel and the evaporator 5. That is, the frequency conversion board assembly 4 is arranged adjacent to the condenser 6, so that the air preheated by the frequency conversion board assembly 4 can exchange heat with the condenser 6 after a short distance.
