In the following, a heat pump mounting box 1 for a heat pump drier or washer-drier machine according to embodiments of a first aspect of the present invention will be described with reference to
As shown in
Specifically, the base 100 is provided with an air suction port 101, a two-device mounting chamber 110, a compressor mounting chamber 120, a cooling air supplement port 121 and a bypass orifice 131. The compressor mounting chamber 120 is in communication with the outside through the cooling air supplement port 121, and the two-device mounting chamber 110 is in communication with the compressor mounting chamber 120 through the bypass orifice 131. The air passage guide plate is mounted to the base 100 and defines, together with the base 100, an air guide passage 210 that has a drying air inlet 211 in communication with the air suction port 101 and a drying air outlet 212 in communication with the two-device mounting chamber 110. The cover plate 300 is mounted over the base 100 and at least covers the two-device mounting chamber 110.
The term “two-device” in “the two-device mounting chamber 110” refers to an evaporator and a condenser that constitute the heat pump drying system, and the evaporator and the condenser are mounted within the two-device mounting chamber 110 separately. The compressor mounting chamber 120 is configured to mount a compressor of the heat pump drying system to implement heat exchange between the drying air and both of the evaporator and the condenser. It can be understood that the heat pump drying system may further include a throttling device, a fan, a sealing member, a damping member and a filtering device.
It can also be understood that the description that “the cover plate 300 at least covers the two-device mounting chamber 110” includes the following four situations: the cover plate 300 only covers the two-device mounting chamber 110; the cover plate 300 covers the two-device mounting chamber 110 and the compressor mounting chamber 120; the cover plate 300 covers the two-device mounting chamber 110 and the air passage guide plate; the cover plate 300 covers the two-device mounting chamber 110, the compressor mounting chamber 120 and the air passage guide plate.
Consequently, the drying air enters the air guide passage 210 via the drying air inlet 211 and enters the two-device mounting chamber 110 via the drying air outlet 212; ambient air enters the compressor mounting chamber 120 via the cooling air supplement port 121 and enters the two-device mounting chamber 110 via the bypass orifice 131. In such a way, the ambient air of relatively low temperature is mixed with the drying air of relatively high temperature, and takes away part of heat of the condenser when passing across the condenser, so as to lower the temperature of the condenser and avoid the overheating of the heat pump drying system; moreover, since the humidity of the drying air is greater than that of the ambient air, the mixed air has a smaller humidity than the original drying air before mixing, so as to improve the clothes drying performance of the heat pump drier or washer-drier machine.
In conclusion, the heat pump mounting box 1 according to the embodiments of the present invention employs the cooling air supplement port 121 and the bypass orifice 131 to implement the function of supplementing cooling air, such that the dry ambient air of low temperature may enter the two-device mounting chamber 110 from the compressor mounting chamber 120 and be mixed with the drying air of high humidity and high temperature, so as to lower the temperature of the condenser and avoid the overheating of the heat pump drying system, thereby improving the clothes drying performance of the heat pump drier or washer-drier machine.
According to some embodiments of the present invention, as shown in
Therefore, the drying air in the air guide passage 210 enters the evaporator mounting section 111 through the drying air outlet 212, enters the condenser mounting section 112 after heat exchange with the evaporator in the evaporator mounting section 111, and then exchanges heat with the condenser; meanwhile, the ambient air directly enters the condenser mounting section 112 through the bypass orifice 131, or first enters the passage section 113 and then enters the condenser mounting section 112, or enters the condenser mounting section 112 and the passage section 113 separately, so as to lower the temperature of the condenser.

As shown in
Specifically, the base 100 is provided with the air suction port 101, the two-device mounting chamber 110, the compressor mounting chamber 120, the cooling air supplement port 121 and the bypass orifice 131. The two-device mounting chamber 100 includes the evaporator mounting section 111 and the condenser mounting section 112 communicated with each other, as well as the passage section 113 located between the evaporator mounting section 111 and the condenser mounting section 112. The compressor mounting chamber 120 is in communication with the outside through the cooling air supplement port 121; the condenser mounting section 112 and the compressor mounting chamber 120 are communicated with each other through the bypass orifice 131, and the passage section 113 and the compressor mounting chamber 120 are communicated with each other through the bypass orifice 131. The air passage guide plate is mounted to the base 100 and defines, together with the base 100, the air guide passage 210 that has the drying air inlet 211 in communication with the air suction port 101 and the drying air outlet 212 in communication with the evaporator mounting section 111. The cover plate 300 is mounted over the base 100 and at least covers the two-device mounting chamber 110, the compressor mounting chamber 120 and the air passage guide plate.
The two-device mounting chamber 110 and the compressor mounting chamber 120 are separated from each other by the partition plate 130 that extends on the base 100 in the left-and-right direction, and the partition plate 130 constitutes a rear wall of the compressor mounting chamber 120 and a front wall of the two-device mounting chamber 110. The bypass orifice 131 is disposed in the partition plate 130 and extends along the left-and-right direction, and is defined by the gap between the top of the partition plate 130 and the cover plate 300. The partition plate 130 is further provided with four pipe-through holes 132 running through the partition plate 130 along the thickness direction thereof; two pipe-through holes 132 at the left side lead to the evaporator mounting section 111 while two pipe-through holes 132 at the right side lead to the condenser mounting section 112; the two pipe-through holes 132 at the left side are in communication with the bypass orifice 131. The cooling air supplement port 121 is disposed in the front wall of the compressor mounting chamber 120 and right opposite the condenser mounting section 112; the base 100 is provided with the air guide flange 140 located at the exterior of the compressor mounting chamber 120 and surrounding the cooling air supplement port 121.
Consequently, the drying air enters the air guide passage 210 via the drying air inlet 211, enters the evaporator mounting section 111 via the drying air outlet 212, enters the condenser mounting section 112 after heat exchange with the evaporator in the evaporator mounting section 111, and exchanges heat with the condenser; meanwhile, the dry ambient air of low temperature enters the compressor mounting chamber 120 from front to rear via the cooling air supplement port 121, enters the condenser mounting section 112 and the passage section 113 separately through the bypass orifice 131 after passing across the compressor, to be mixed with the drying air of high humidity and high temperature, and then takes away part of the heat on the condenser when passing across the condenser, so as to cool down the condenser and avoid the overheating of the heat pump drying system.
In conclusion, the heat pump mounting box 1 according to the embodiments of the present invention employs the cooling air supplement port 121 and the bypass orifice 131 to implement the function of supplementing cooling air, so as to lower the temperature of the condenser and avoid the overheating of the heat pump drying system, thereby improving the clothes drying performance of the heat pump drier or washer-drier machine.
