[0002] Dryers can be divided into two types: industrial and civil. Industrial dryers are also called drying equipment or dryers. Civil dryers are a type of washing machinery. They are generally used to remove moisture from clothing and other textiles after washing and dehydration. Air energy heat pump dryers are also needed in the production process to dry vegetables.

[0003] When traditional drying equipment is in use, the hot air is directly discharged after circulating in the space. The hot air after circulating in the space often contains a certain amount of heat, which cannot be utilized if directly discharged. Traditional equipment lacks the ability to recover the waste heat in the hot air, which leads to a certain degree of energy waste. Utility Model Content

[0007] As a preferred technical solution of the utility model: one end of the connecting pipe is connected to the outlet of the condenser, and the other end of the connecting pipe is connected to the inlet of the evaporator.

[0008] As a preferred technical solution of the utility model: the inner cavity of the inlet pipe away from the end of the refrigerant pipe is communicated with the inner cavity of the input pipe, and the inner cavity of the outlet pipe away from the end of the refrigerant pipe is communicated with the inner cavity of the output pipe.

[0009] As a preferred technical solution of the utility model: the outer wall of the air duct passes through the outer wall of the shell, and the inner cavity of the air duct is communicated with the outer wall of the condenser.

[0010] As a preferred technical solution of the utility model: the inner cavity of the recovery bin is communicated with the inner cavities of the exhaust pipe and the drain pipe, and the bottom of the inner cavity of the recovery bin is inclined toward the drain pipe.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The heat recovery and condensate water recovery structure of the fan in the dryer is realized by setting a recovery bin at the bottom of the shell. The refrigerant with a lower temperature coming out of the evaporator will enter the inner cavity of the refrigerant pipe, and then the refrigerant pipe will fully contact with the hot air entering from the air inlet pipe to increase the temperature of the refrigerant.

After the hot air contacts the outer wall of the refrigerant pipe, the temperature of the hot air decreases, and then the water vapor in the hot air condenses on the outer wall of the refrigerant pipe and falls to the bottom of the recovery bin, and then is discharged under the action of the drain pipe. The temperature of the hot air after recovery decreases and is discharged from the equipment through the exhaust duct. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A heat recovery and condensate water recovery structure for a fan in a dryer comprises a shell 1, a condenser 2 is fixedly mounted in the inner cavity of the shell 1, an evaporator 3 is installed on the inner wall of the shell 1, a connecting pipe 4 is installed on the outer wall of the condenser 2, a compressor 5 is fixedly mounted in the inner cavity of the shell 1, an input pipe 6 is fixedly mounted on the top of the compressor 5, an output pipe 7 is installed on the outer wall of the compressor 5, an air duct 8 is fixedly mounted on the outer wall of the shell 1, an exhaust fan 9 is fixedly mounted in the inner cavity of the air duct 8, an air inlet pipe 10 is fixedly mounted on the outer wall of the shell 1, a recovery bin 11 is installed in the inner cavity of the shell 1, a drain pipe 12 is fixedly mounted on the outer wall of the recovery bin 11, an exhaust pipe 13 is fixedly mounted on the outer wall of the recovery bin 11, a refrigerant pipe 14 is fixedly mounted in the inner cavity of the recovery bin 11, an inlet pipe 15 is installed on the outer wall of the refrigerant pipe 14, and an outlet pipe 16 is installed on the outer wall of the refrigerant pipe 14.

[0022] By installing the refrigerant pipe 14 in the inner cavity of the recovery bin 11, when the circulated hot air enters the inner cavity of the recovery bin 11 through the air inlet pipe 10, the hot air will fully contact the outer wall of the refrigerant pipe 14, thereby transferring the heat in the hot air to the refrigerant in the inner cavity of the refrigerant pipe 14, thereby realizing the effect of heat recovery and utilization.

[0023] In a preferred embodiment: one end of the output pipe 7 away from the compressor 5 is connected to the inlet of the condenser 2, one end of the input pipe 6 away from the compressor 5 is connected to the outlet of the evaporator 3, and the other end of the input pipe 6 is connected to the inlet of the compressor 5.

[0024] Through the output pipe 7 set on the outer wall of the compressor 5, the refrigerant that has absorbed the heat in the air is converted into a high-temperature and high-pressure gas under the action of the compressor 5, and then the high-temperature and high-pressure gas is transmitted into the inner cavity of the condenser 2 through the output pipe 7, and the temperature is released under the action of the condenser 2.

[0025] In a preferred embodiment, one end of the connecting pipe 4 is connected to the outlet of the condenser 2 , and the other end of the connecting pipe 4 is connected to the inlet of the evaporator 3 .

[0026] By setting a connecting pipe 4 at the outlet of the condenser 2, the condenser 2 and the evaporator 3 are connected using the connecting pipe 4. The high-temperature and high-pressure gas in the inner cavity of the condenser 2 will release heat after passing through the condenser 2, and then enter the inner cavity of the evaporator 3 through the connecting pipe 4, and the temperature of the refrigerant is reduced under the action of the evaporator 3.

[0027] In a preferred embodiment, the inner cavity of the inflow pipe 15 away from the refrigerant pipe 14 communicates with the inner cavity of the input pipe 6 , and the inner cavity of the outflow pipe 16 away from the refrigerant pipe 14 communicates with the inner cavity of the output pipe 7 .

[0028] Under the action of the inflow pipe 15, the refrigerant coming out of the inner cavity of the evaporator 3 is introduced into the inner cavity of the refrigerant pipe 14. At this time, the temperature of the refrigerant is relatively low after passing through the evaporator 3. When the hot air after circulation enters the inner cavity of the recovery bin 11, the hot air will contact the outer wall of the refrigerant pipe 14, thereby transferring heat to the refrigerant in the inner cavity of the refrigerant pipe 14, and then transferring the refrigerant to the inner cavity of the output pipe 7 through the outflow pipe 16.

[0029] In a preferred embodiment, the outer wall of the air duct 8 passes through the outer wall of the housing 1 , and the inner cavity of the air duct 8 communicates with the outer wall of the condenser 2 .

[0030] Through the air duct 8 arranged on the outer wall of the shell 1 and the multiple exhaust fans 9 arranged in the inner cavity of the air duct 8, a large amount of heat will be released under the action of the condenser 2, so that the air temperature around the condenser 2 will increase. At this time, under the action of the air duct 8 and the exhaust fans 9, the hot air is drawn out from around the condenser 2 for utilization.

[0031] In a preferred embodiment, the inner cavity of the recovery bin 11 is communicated with the inner cavities of the exhaust pipe 13 and the drain pipe 12 , and the bottom of the inner cavity of the recovery bin 11 is inclined toward the drain pipe 12 .

[0032] Through the drain pipe 12 and the exhaust pipe 13 arranged on the outer wall of the recovery bin 11, after the hot air contacts the outer wall of the refrigerant pipe 14, the heat is transferred to the refrigerant in the inner cavity of the refrigerant pipe 14. During the heat transfer process, the water vapor contained in the hot air will condense on the outer wall of the refrigerant pipe 14, and then fall to the bottom of the inner cavity of the recovery bin 11, and then be discharged from the inner cavity of the recovery bin 11 through the drain pipe 12.

[0033] Working principle: During the use of the above-mentioned equipment, the refrigerant is converted into a high-temperature and high-pressure gas under the action of the compressor 5, and is released into the inner cavity of the condenser 2 under the action of the output pipe 7. At this time, the heat is released outward under the action of the condenser 2, so that the temperature of the air around the condenser 2 increases, and then the hot air near the condenser 2 is drawn into the inner cavity of the air duct 8 under the action of the exhaust fan 9, so as to be utilized to dry the material. After passing through the condenser 2, the high-temperature refrigerant will enter the inner cavity of the evaporator 3 under the action of the connecting pipe 4, and then the temperature of the high-temperature refrigerant will be reduced under the action of the evaporator 3. After passing through the evaporator 3, it will enter the inner cavity of the compressor 5 through the input pipe 6 to achieve the refrigerant temperature control. The hot air will fully contact the refrigerant pipe 14 after being discharged from the evaporator 3 in the inner cavity of the refrigerant pipe 14, and the heat will be transferred to the refrigerant to increase its temperature, and then enter the inner cavity of the condenser 2 through the outflow pipe 16 to recover the heat in the hot air. In the process of temperature transfer, the water vapor in the hot air will condense on the outer wall of the refrigerant pipe 14 and fall to the bottom of the recovery bin 11, and then be discharged through the drain pipe 12. The air after heat recovery will be released to the outside through the exhaust pipe 13.
