Description
- The present invention relates to the field of heating and dehumidifying of heat pumps, and in particular to a heat pump system, a washing-drying integrated machine and a clothes dryer.
- Clothes dryers in the existing art include a direct-drainage type clothes dryer and a condensation type clothes dryer; both the direct-drainage type clothes dryer and the condensation type clothes dryer are prepared in a way that an air inflow passage and an air outflow passage are communicated with a drum in a tank body; a difference between the direct-drainage type clothes dryer and the condensation type clothes dryer is that a heater for heating air flowing into a washing drum is mounted in the air inflow passage of the direct-drainage type clothes dryer; the air inflow passage and the air outflow passage of the condensation type clothes dryer are communicated to form an air duct; not only a heating device for heating the air flowing into the washing drum and a fan for feeding the air heated by the heating device into the drum are mounted in the air duct, but also a condensing device for cooling a high-temperature gas flowing out of the washing drum is mounted; and similarly, drying systems of existing washing-drying integrated machines are same as those of the clothes dryers.
- In the existing art, many direct-drainage type clothes dryers or washing-drying integrated machines adopt a heat pump drying mode in a drying process; heat pump systems in the washing-drying integrated machines or clothes dryers adopting the heat pump drying mode are used for dehumidifying and heating the air flowing through the air duct; the heat pump system includes an evaporator, a compressor, a condenser and a throttling device; the evaporator, the compressor, the condenser and the throttling device are sequentially communicated through a pipeline to form a refrigerant circulating loop; the evaporator of the heat pump system is arranged at an air inlet of the air duct; the evaporator evaporates a liquid refrigerant into a gaseous refrigerant when refrigerant in the heat pump system enters the evaporator; in this process, the evaporator absorbs surrounding heat, as a condensing device in the air duct used for condensing the air flowing through the air duct; the condenser of the heat pump system is located in the air duct between a fan and the evaporator; the condenser changes a high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure gaseous refrigerant when the refrigerant in the heat pump system enters the condenser; and at the moment, the condenser releases heat to the outside, as a heating device in the air duct used for heating the air flowing through the air duct.
- However, for a drum type washing-drying integrated machine or clothes dryer adopting the heat pump drying mode in the existing art, since the temperature of water for rinsing clothes is only slightly higher than 0 DEG C in a low-temperature environment such as 0 DEG C environment, the temperature of the air blowing out from a washing/drying drum is close to 0 DEG C at a stage of starting to dry; in this case, a saturation temperature under a refrigerant saturation pressure in the evaporator of the heat pump system is much lower than 0 DEG C, a load of a compressor system is low, and an input power is small; but the heat for drying the air comes from power input of the compressor system, so the rise of the temperature in the washing/drying drum is extremely slow, which is adverse to the efficiency of drying clothes; and when a evaporation temperature is kept below 0 DEG C for a long time in the low-temperature environment, the evaporator is in contact with moist air blown out of the drum, a large number of frost may be condensed on surfaces of fins of the evaporator, an effective area of the evaporator is reduced, and the circulation of the air in a circulating air duct may be blocked, causing that the refrigerant in the compressor system cannot be completely vaporized, and a liquid-state refrigerant enters the compressor along an air suction pipe of the compressor, leading to a failure of the compressor.
- Existing solutions are that (1) an auxiliary heating pipe (wire) is added behind the condenser, and the air heated by the condenser continues to be reheated by the heating pipe (wire), to obtain a higher drying temperature in the low-temperature environment, but an energy consumption level may be increased; (2) a frequency conversion compressor is adopted to operate at a higher operation frequency at a low temperature or when the drying needs to be accelerated, but costs are increased greatly; (3) a high-capacity compressor is adopted, but energy consumption of the high-capacity compressor may be higher at room temperature; and (4) a multi-exhaust-chamber compressor is adopted, but this solution may also increase operation costs.
- In view of the above descriptions, there is an urgent need for a new heat pump system to solve problems that a drying efficiency of clothes is low and the compressor is easy to have a failure in the existing art.
- In view of this, an objective of the present invention is to provide a heat pump system which can increase a load rise rate of a compressor in a low-temperature environment.
- A further objective of the present invention is to provide a washing-drying integrated machine in which the above heat pump system is arranged to increase the drying efficiency of clothes.
- Another objective of the present invention is to provide a clothes dryer in which the above heat pump system is arranged to increase the drying efficiency of the clothes.
- Embodiments of the present invention adopt the following technical solutions:
- A heat pump system includes an evaporator, a compressor, a condenser and a refrigerant regulating subsystem; where the evaporator, the compressor, the condenser and the refrigerant regulating subsystem are sequentially communicated through a pipeline to form a refrigerant circulating loop; and the refrigerant regulating subsystem includes a first branch and a second branch connected in parallel between the evaporator and the condenser;
the first branch includes a first throttling device having an outlet connected with a pipe inlet of the evaporator, and a liquid storing device located between the first throttling device and the condenser; and

- Preferably, the first throttling device is a first capillary tube; the second throttling device is a second capillary tube; and the length of the first capillary tube is smaller than that of the second capillary tube.
- Preferably, the first throttling device and the second throttling device are a same electronic expansion valve; and an opening degree of the electronic expansion valve is adjustable.
- Preferably, both the first throttling device and the second throttling device are electronic expansion valves; and opening degrees of all the electronic expansion valves are adjustable.
- Preferably, check valves are respectively arranged on the first branch between the liquid storing device and the first throttling device and the second branch between the second throttling device and the electromagnetic valve.
- A washing-drying integrated machine includes an outer drum, an air duct and an inner drum arranged in the outer drum; an air inlet and an air outlet of the air duct are respectively connected with a rear part and a front part of the outer drum; the air duct and the outer drum form a closed loop; a fan is arranged in the air duct; the washing-drying integrated machine further includes the heat pump system according to any of the above; the evaporator of the heat pump system is arranged at the air inlet of the air duct, for condensing air flowing through the air duct; and the condenser of the heat pump system is located in the air duct between the fan and the evaporator, for heating air flowing through the air duct.
- A clothes dryer includes a tank body, an air duct and a drying drum mounted in the tank body; an air inlet and an air outlet of the air duct are respectively connected with a rear part and a front part of the drying drum to form a closed loop together with the drying drum; a fan is arranged in the air duct; the clothes dryer further includes the heat pump system according to any of the above; the evaporator of the heat pump system is arranged at the air inlet of the air duct, for condensing air flowing through the air duct; and the condenser of the heat pump system is located in the air duct between the fan and the evaporator, for heating air flowing through the air duct.
- Preferably, an auxiliary electric heating device is arranged in the air duct between the fan and the air outlet of the air duct.
- The technical solutions proposed by embodiments of the present invention have beneficial technical effects that
- (1) the refrigerant regulating subsystem of the heat pump system includes the first branch and the second branch connected between the evaporator and the condenser in parallel; the first branch includes the first throttling device having the outlet connected with the pipe inlet of the evaporator, and the liquid storing device located between the first throttling device and the condenser; the second throttling device is connected with the second branch in series; a flow direction of the refrigerant is the compressor, the condenser, the first branch (the liquid storing device and the first throttling device), the evaporator and the compressor when an environment temperature is high; the flow direction of the refrigerant is the compressor, the condenser, the second branch (the second throttling device), the evaporator and the compressor when an environment temperature is low; therefore, when the temperature is high, the liquid storing device enables a space for accommodating the refrigerant to increase, and pressure load does not increase rapidly; while at a low temperature, the refrigerant enters the evaporator only through the second throttling device from the condenser, since the space for accommodating the refrigerant is reduced, a compressor load may rise rapidly, thereby increasing a load rise rate of the compressor in the low-temperature environment.
- (2) the length of the first capillary tube is smaller than that of the second capillary tube, i.e., the length of the second capillary tube is longer, and the capillary tube is set to be longer at the low temperature in order to match a superheat degree of the evaporator in this environment, avoid incomplete evaporation since a pressure rises rapidly and excessive refrigerant enters the evaporator, and avoid a problem of a failure of the compressor since a liquid-state refrigerant enters the compressor along an air suction pipe of the compressor.

electromagnetic valve 116 can also be arranged on the first branch 11 between thecondenser 2 and theliquid storing device 114, and a secondelectromagnetic valve 122 is arranged on thesecond branch 12 between thesecond throttling device 121 and the pipe outlet of thecondenser 2; both the firstelectromagnetic valve 116 and the secondelectromagnetic valve 122 are connected with the controller; the controller controls the flow direction of the refrigerant flowing out of thecondenser 2 by controlling opening or closing of the firstelectromagnetic valve 116 or the secondelectromagnetic valve 122, and controls the refrigerant to flow through the first branch 11 or thesecond branch 12; and therefore, the purpose of adopting the electromagnetic valves is also to control refrigerant to switch between two flow directions. - An operation process of the heat pump system is described below:
- When an environment temperature is high, the flow direction of the refrigerant is that high-temperature and high-pressure gaseous refrigerant flowing out of the
compressor 4 flows through thecondenser 2 and is changed into a liquid condensing agent after being condensed by thecondenser 2; in this process, thecondenser 2 releases heat to the outside; the liquid condensing agent enters theliquid storing device 114 through the reversing valve; theliquid storing device 114 temporarily stores the refrigerant; then the refrigerant enters theevaporator 3 from theliquid storing device 114 through thefirst throttling device 111; theevaporator 3 evaporates the liquid refrigerant into gaseous refrigerant; in this process, theevaporator 3 absorbs the surrounding heat; and the gaseous refrigerant enters thecompressor 4 along the pipeline. - When the environment temperature is low, the flow direction of the refrigerant is that high-temperature and high-pressure gaseous refrigerant flowing out of the
compressor 4 flows through thecondenser 2 and is changed into the liquid condensing agent after being condensed by thecondenser 2; in this process, thecondenser 2 releases heat to the outside; the liquid condensing agent enters thesecond branch 12 through the reversing valve, enters thesecond throttling device 121 along thesecond branch 12, and then flows to theevaporator 3; theevaporator 3 evaporates the liquid refrigerant into gaseous refrigerant; in the process, theevaporator 3 absorbs the surrounding heat; and the gaseous refrigerant enters thecompressor 4 along the pipeline. - Therefore, when the temperature is high, pressure load would not rise rapidly since the refrigerant is accommodated in a space of the
liquid storing device 114; while at a low temperature, thecompressor 4 is started, the reversing valve is first closed to return the refrigerant in theliquid storing device 114 to a refrigeration system under an effect of thecompressor 4; then the reversing valve is communicated with thesecond branch 12, so that the refrigerant is subjected to circulation of the drying process; and the load of thecompressor 4 would rise rapidly since the space for accommodating the refrigerant is reduced. - In the present embodiment, as a preferred solution, the
first throttling device 111 is a first capillary tube, and thesecond throttling device 121 is a second capillary tube. - In the present embodiment, as a preferred solution, the length of the first capillary tube is smaller than that of the second capillary tube, and the second capillary tube is set to be longer in order to match a superheat degree of the
evaporator 3 in a low-temperature state, thereby avoiding incomplete evaporation since a pressure rises rapidly and excessive refrigerant enters theevaporator 3. - Definitely, selection of the
first throttling device 111 and thesecond throttling device 121 is not limited to this; electronic expansion valves may be used respectively as thefirst throttling device 111 and thesecond throttling device 121; the electronic expansion valves on the two branches are respectively connected with the controller; the electronic expansion valves regulate respective opening degrees according to command signals sent by the controller; and the opening degree of the electronic expansion valve on the first branch 11 during normal operation is greater than that of the electronic expansion valve on thesecond branch 12 during normal operation. - The same electronic expansion valve may also be used as the
first throttling device 111 and thesecond throttling device 121; the electronic expansion valve is connected with the controller; the electronic expansion valve regulates the opening degree according to the command signal sent by the controller; when the system uses different branches, opening degrees of the electronic expansion valve are also different; normally, the opening degree of the electronic expansion valve when the first branch 11 is operated normally is greater that of the electronic expansion valve when thesecond branch 12 is operated normally. - In the present embodiment, as a preferred solution, a
first check valve 112 is arranged on the first branch 11 between theliquid storing device 114 and thefirst throttling device 111; and thefirst check valve 112 plays a role of preventing the refrigerant from flowing back into theliquid storing device 114 during operation in a low-temperature mode. - In the present embodiment, if a distance from the second
electromagnetic valve 122 on thesecond branch 12 to the second capillary tube is large, a second check valve may also be arranged on the second branch 113 between thesecond throttling device 121 and the secondelectromagnetic valve 122, to avoid accumulating the refrigerant or lubricating oil in the pipeline in a state of high environment temperature. - In the present embodiment, as a preferred solution, the
liquid storing device 114 is a liquid storing tank, but certainly is not limited hereto; and the liquid storing device may also be selected. - The present invention also provides a clothes dryer, as shown in
Fig. 2 ; the clothes dryer includes atank body 6, anair duct 5 and adrying drum 7 mounted in thetank body 6; anair inlet 51 and anair outlet 52 of theair duct 5 are respectively connected with a rear part and a front part of thedrying drum 7; theair duct 5 and thedrying drum 7 form a closed loop; a fan 54 is arranged in theair duct 5; the clothes dryer further includes the above heat pump system; theevaporator 3 of the heat pump system is arranged at theair inlet 51 of theair duct 5, as a condensing device in theair duct 5, for condensing air flowing through theair duct 5; and thecondenser 2 of the heat pump system is located in theair duct 5 between the fan 54 and theevaporator 3, as a heating device in theair duct 5, for heating the air flowing through theair duct 5. - In the present embodiment, as a preferred solution, an auxiliary
electric heating device 53 is arranged in theair duct 5 between the fan 54 and theair outlet 52 of theair duct 5, for further heating the air flowing through theair duct 5. - In the present embodiment, as a preferred solution, a

air duct 5 and the dryingdrum 7 in a circulation manner, while thecondenser 2 of the heat pump system heats the air flowing therethrough; hot air enters the dryingdrum 7, to evaporate out and take away water vapor in clothes; then the air containing the water vapor passes through theevaporator 3 of the heat pump system; theevaporator 3 absorbs the surrounding heat to cool the surrounding air so that the water vapor in the hot air is condensed into liquid water and is drained out of a machine along with tap water; dry air from which the water vapor is removed is reheated by thecondenser 2 of the heat pump system and re-enters the dryingdrum 7 to dry the clothes; and this process is continuously circulated until the clothes are dried. - The present application further provides a washing-drying integrated machine; the washing-drying integrated machine includes an outer drum, an air duct and an inner drum arranged in the outer drum; an air inlet and an air outlet of the air duct are respectively connected with a rear part and a front part of the outer drum; the air duct and the outer drum form a closed loop; and a fan is arranged in the air duct.
