Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 is a schematic block diagram of a dehumidifier 10 according to an embodiment of the present invention, referring to fig. 1, the dehumidifier 10 may include a refrigeration system, a fan 140, and a water-cooled pipe 123, wherein the refrigeration system may include a compressor 110, a condenser 120, and an evaporator 130 connected in sequence by refrigerant lines, the condenser 120 and the evaporator 130 being laterally spaced apart from each other to define an air flow path, the fan 140 being disposed at a side of the condenser 120 remote from the evaporator 130 and configured to controllably rotate such that an air flow flows from the side of the evaporator 130 to the condenser 120, and the water-cooled pipe 123 being configured to circulate cooling water to water-cool the air flow flowing through the condenser 120.

In the dehumidifier 10 of the embodiment of the present invention, the condenser 120 and the evaporator 130 are transversely arranged at intervals, and define an airflow channel therebetween, when the fan 140 works, the air can drive the airflow to flow from one side of the evaporator 130 to the condenser 120, and the condenser 120 is provided with the water cooling pipe 123. After the dehumidifier 10 enters the cooling and dehumidifying mode, the circulating cooling water may be introduced into the water cooling pipe 123, the heat exchange efficiency of the condenser 120 may be improved by the cooling effect of the cooling water, and the air flow flowing through the condenser 120 may be cooled. Thus, not only the cooling effect of the dehumidifier 10 is improved, but also the purposes of energy saving and consumption reduction are achieved, and the user experience of the dehumidifier 10 is enhanced.

In an alternative embodiment of the present invention, the water cooling pipe 123 may be located in a housing of the condenser 120 adjacent to the blower 140, and the condensation pipe of the condenser 120 may be located in a housing of the condenser 120 adjacent to the evaporator 130. By partially disposing the water cooling pipe 123 inside the condenser 120, not only is the fixing and installation of the water cooling pipe 123 facilitated, but also the cooling capacity loss of the water cooling pipe 123 can be reduced, and the water cooling effect can be ensured.

As shown in fig. 1, the evaporator 130, the condenser 120 and the blower 140 of the dehumidifier 10 are sequentially arranged at intervals from left to right, the condenser pipe is positioned at the left side inside the housing of the condenser 120, and the water cooling pipe 123 is positioned at the right side inside the housing of the condenser 120. When the water cooling pipe 123 is supplied with cooling water, the air flow blown out by the fan 140 is equivalent to the air cooling effect and the water cooling effect in sequence, so that the cooling effect is more remarkable.

Fig. 2 is a longitudinal sectional view of a condensing duct according to an embodiment of the present invention, and referring to fig. 2, an inner pipe 121 of the condensing duct is communicated with a water cooling pipe 123 for circulating cooling water, and an outer pipe 122 of the condensing duct is communicated with a refrigerant pipe for circulating refrigerant. In this way, under the condition that the cooling water circulation loop and the refrigerant circulation loop are not interfered with each other, the water cooling area of the water cooling pipe 123 can be increased, after the dehumidifier 10 enters the cooling and dehumidifying mode, the condenser 120 performs heat exchange with the evaporator 130, and the refrigerant in the outer pipe 122 of the condensing pipe also performs heat exchange with the cooling water in the inner pipe 121, so that the heat exchange efficiency of the condenser 120 can be further enhanced, the cooling effect of the dehumidifier 10 is more obvious, and the cooling effect and the energy-saving effect of the dehumidifier 10 in the cooling and dehumidifying mode can be greatly improved. It will be appreciated that the dehumidifier 10 provided with such a condenser tube and water cooling tube 123 is particularly suitable for users who are in hot and humid areas for a long period of time.

The condenser 120 of the invention is of a novel structure, the side of the condenser 120 close to the evaporator 130 is a double-pipe heat exchanger, the inner pipe 121 is a water flow path, the outer pipe 122 is a refrigerant (such as Freon) flow path, the right side is a water flow path (common hairpin pipe), and the right side is provided with fins, when the water flow path supplies water, air cooling and water cooling are simultaneously used, so that the heat exchange efficiency of the condenser 120 is enhanced, and the purposes of saving energy and reducing the air outlet temperature are achieved.

In another alternative embodiment of the present invention, the condensing tube may have a sleeve structure, an inner tube 121 of the condensing tube is connected to the refrigerant tube for circulating the refrigerant, and an outer tube 122 of the condensing tube is connected to the water cooling tube 123 for circulating the cooling water. In this way, after the dehumidifier 10 enters the temperature rising mode, the supply of the cooling water to the water cooling pipe 123 is stopped, at this time, no cooling water is in the water cooling pipe 123, no cooling water is in the outer pipe 122 of the condensation pipe, the outer pipe 122 can form the air heat insulation layer of the inner pipe 121, and the heat exchange efficiency of the condenser 120 can be reduced through the heat insulation effect of the outer pipe 122, so that the temperature rising effect of the dehumidifier 10 in the temperature rising and dehumidification mode is more remarkable. It will be appreciated that the dehumidifier 10 provided with such a condenser pipe and water cooling pipe 123 is particularly suitable for users who are in cold and humid areas for a long period of time.

The condenser 120 of the invention is of a novel structure, the side of the condenser 120 close to the evaporator 130 is a double-pipe heat exchanger, the inner pipe 121 is a refrigerant (such as Freon) flow path, the outer pipe 122 is a water flow path, when the air outlet temperature needs to be improved during clothes drying and the like, only air cooling effect is achieved, no cooling water exists in the outer pipe 122 at this time, the outer pipe 122 can form an air heat insulation layer of the inner pipe 121, the heat exchange efficiency between the condenser 120 and the evaporator 130 is reduced, and therefore the purpose of improving the air outlet temperature is achieved.

In the embodiment of the present invention, the portion of the water cooling pipe 123 in the condenser 120 may be bent into an S-shape that is disposed side by side from top to bottom, or may be bent into an S-shape that is disposed side by side from left to right, so as to increase the contact area between the water cooling pipe 123 and the air flow, thereby improving the cooling effect of the dehumidifier 10 in the cooling and dehumidifying mode. Of course, the bending form of the water cooling pipe 123 may be variously changed, and the present invention is not limited thereto.

In an alternative embodiment of the present invention, the dehumidifier 10 may further include a water tray 150 and a water tank 160, where the water tray 150 is disposed below the evaporator 130, and is mainly used for containing condensed water flowing down from the evaporator 130 during the operation of the refrigeration system, and in practical applications, the space below the evaporator 130 and the condenser 120 may be the water tray 150. The water tank 160 is disposed below the water tray 150, and is mainly used for receiving condensed water from the water tray 150. When the water tank 160 is full, the normal operation of the dehumidifier 10 can be maintained by manual drainage or water drainage of the water pump 170, so that the dehumidifier 10 is prevented from waiting for a long time due to full water shutdown, and the use experience of a user is prevented from being affected.

Specifically, a drain port may be provided at one side of the water tray 150, and the water tank 160 may be drawably provided below the drain port from one side of the water tray 150. In this way, the condensed water received by the water receiving tray 150 can continuously flow into the water tank 160 through the water outlet, and only the water tank 160 needs to be drained afterwards.

In an alternative embodiment of the present invention, a water pump 170 is disposed in the water tank 160, the water inlet end of the water cooling pipe 123 may be connected to the water pump 170, and the water outlet end of the water cooling pipe 123 may extend into or above the water tank 160. That is, the condensed water in the water tank 160 can be sent to the water cooling pipe 123 as the cooling water pump 170 to realize recycling of the condensed water, and the condensed water is used for assisting water cooling, so that the air outlet temperature of the dehumidifier 10 can be effectively reduced, and the purposes of energy saving and consumption reduction are achieved.

It will be appreciated that during operation of the dehumidifier 10, the refrigerant discharged from the compressor 110 in a high temperature and high pressure state dissipates heat in the condenser 120, and absorbs heat in the evaporator 130 to flow back to the compressor 110. Because the surface temperature of the evaporator 130 is lower than the ambient temperature, the indoor air is separated out by water after being cooled by the evaporator 130 to form condensed water, and the condensed water at the moment has lower temperature and can be directly used as cooling water in the water cooling pipe 123, so that the processing cost of the cooling water is saved.

In an alternative embodiment of the present invention, the water inlet end of the water cooling pipe 123 may be connected with a drain pipe 180, and a reversing valve 190 may be provided at the connection, and the reversing valve 190 may be configured to controllably switch the valve direction so that condensed water in the water tank 160 circulates through the water cooling pipe 123 or is drained out of the water tank 160 through the drain pipe 180.

When the water tank 160 is full, the drain pipe 180 may be switched in advance to drain the condensed water in the water tank 160 in order to maintain the operation state of the dehumidifier 10, thereby preventing the condensed water from overflowing the water tank 160. After the dehumidifier 10 enters the cooling and dehumidifying mode, the water pump 170 sends the condensed water in the water tank 160 to the water cooling pipe 123 and exchanges heat at the condenser 120, so that after the condensed water circulates for a period of time, the water temperature can obviously rise, and when the water temperature is greater than or equal to the ambient temperature, the water cooling effect cannot be achieved, and at the moment, the reversing valve 190 should be switched to the drain pipe 180, so that part of the condensed water in the water tank 160 is discharged.

Referring to fig. 1, S1 is a reversing valve 190, where the reversing valve 190 may be a solenoid valve, an electric valve, etc., and the P port is an inlet of the reversing valve 190 and is connected to the water pump 170. The port A and the port B are two outlets of the reversing valve 190, and are respectively connected with the water cooling pipe 123 and the water discharging pipe 180, the port A is opened in the process of auxiliary water cooling, the port B is closed, and the port A is closed and the port B is opened in the process of water discharging.

Fig. 3 is a schematic structural diagram of a reversing valve 190 according to an alternative embodiment of the present invention, referring to fig. 3, the coil of the reversing valve 190 is currently in a de-energized state, the piston 1 opens the a port, the piston 2 closes the B port, and when the coil of the reversing valve 190 is in an energized state, the piston 1 closes the a port, and the piston 2 opens the B port, so that the conducting direction of the reversing valve 190 can be switched relatively easily by controlling the on-off state of the coil.

In other embodiments, a water pump 170 for draining water may be further provided in the water tank 160, and a water inlet end of the drain pipe 180 is connected to the water pump 170. When the drainage logic is performed, the water pump 170 may be activated to drain the condensed water in the water tank 160 through the drain pipe 180. When the water cooling logic is performed, the water pump 170 connected to the water cooling pipe 123 may be activated to pump the condensed water in the water tank 160 into the water cooling pipe 123. In this way, two water pumps 170 are required to be arranged in the water tank 160, which results in a reduced water storage space of the water tank 160 and an improved water discharge frequency, but the reversing valve 190 is not required, so that the control logic of the reversing valve 190 is omitted, and the control complexity is reduced.

It should be noted that, during the operation of the dehumidifier 10, if the water pump 170 and the reversing valve 190 are operated, it needs to be determined whether the water pump 170 is normally turned on or turned off, whether the reversing valve 190 is normally switched, and output a determination conclusion, for example, when the water pump 170 fails, an alarm prompt of the water pump 170 failure is output, and when the reversing valve 190 fails, an alarm prompt of the reversing valve 190 failure is output.

In an alternative embodiment of the present invention, a water level detecting device 161 is disposed inside the water tank 160, and the water level detecting device 161 may be a water level sensor, which is mainly used for acquiring the water level in the water tank 160, and when the water level rises to the full warning level, the reversing valve 190 may be controlled to switch to the drain pipe 180 for conduction, and the water pump 170 is started to drain water.

The water tank 160 is provided with a first temperature detecting device 162 inside, and the fan 140 is provided with a second temperature detecting device 163 on the outer circumference thereof. The first temperature detecting means 162 and the second temperature detecting means 163 may be temperature sensors, the first temperature detecting means 162 mainly detecting the water temperature of condensed water (cooling water) in the water tank 160, and the second temperature detecting means 163 mainly detecting the ambient temperature of the dehumidifier 10 so as to determine whether or not a water draining operation of the water tank 160 is required according to the water temperature of the condensed water and the ambient temperature.

Specific arrangement positions of the water level detection device 161, the first temperature detection device 162 and the second temperature detection device 163 may refer to fig. 1, wherein LT refers to the water level detection device 161, T1 refers to the first temperature detection device 162, and T2 refers to the second temperature detection device 163.

The water level determination and the water temperature determination are performed under control of the first-arrival person. For example, when the water level in the water tank 160 rises to the full guard height, the water pump 170 is directly activated to drain until the water level in the water tank 160 falls to the minimum guard height. When the water temperature in the water tank 160 rises above the ambient temperature and the water level in the water tank 160 is above twice the minimum protection level, the water pump 170 is restarted to drain until the water level in the water tank 160 drops to the minimum protection level.

Here, the water full guard height and the minimum guard height of the water tank 160 may be artificially set, for example, the water full guard height may be 80% of the height of the water tank 160, and the minimum guard height may be 20% of the height of the water tank 160. With the operation of the dehumidifier 10, the condensed water in the water tank 160 is continuously increased, when the water level rises to 80% of the water tank 160, the water discharge logic is triggered, the reversing valve 190 is switched to the water discharge pipe 180, the water pump 170 starts to discharge water, when the water level falls to 20% of the water tank 160, the water pump 170 is closed, and the reversing valve 190 is switched to the water cooling pipe 123.

It should be noted that, if the dehumidifier 10 is in the cooling and dehumidifying mode at this time, the water pump 170 is kept in the closed state, the remaining 20% of the condensed water in the water tank 160 can prevent the water pump 170 from idling, so as to protect the water pump 170, meanwhile, the condensed water condensed on the surface of the evaporator 130 is continuously stored in the water tank 160, the remaining condensed water in the water tank 160 is cooled, the water level of the condensed water in the water tank 160 is raised, and when the water level is greater than or equal to the minimum protection level (i.e. 40% of the water tank 160), the water pump 170 is started to pump the cooling water (condensed water) to the water cooling pipe 123, so as to maintain the normal circulation flow of the cooling water.

In the drainage process, by controlling a part of the condensate water remaining in the water tank 160, the storage speed of the condensate water in the subsequent water tank 160 can be shortened, so that the water level of the condensate water can be raised to the minimum protection height twice as soon as possible, and when the dehumidifier 10 is in the cooling and dehumidifying mode, the water pump 170 is started to assist in water cooling, and the heat exchange efficiency of the condenser 120 is improved.

A filter 171 may be provided at the water inlet of the water pump 170. The filter 171 can prevent foreign matters falling into the water tank 160 from entering the water cooling pipe 123 through the water pump 170, avoid the problems of damage to the water pump 170 or blockage of the water cooling pipe 123, ensure the normal operation of the water pump 170, and improve the reliability of the operation of the water pump 170.

In the embodiment of the invention shown in the drawings, the fan 140 is a centrifugal fan 140. The centrifugal fan 140 can blow the air flow from the periphery to the room, thereby being beneficial to the uniform adjustment of the indoor temperature, preventing the local temperature from being too high or too low and ensuring the use experience of the user.

It should be noted that, without departing from the spirit and the essence of the present invention, a person skilled in the art may set the fan 140 as the axial flow fan 140, and the water cooling pipe 123 is partially disposed between the axial flow fan 140 and the condenser 120, or disposed at the front side of the axial flow fan 140, so as to achieve the dual cooling effect of water cooling and air cooling, but this falls within the scope of the present invention.

According to any one of the optional embodiments or the combination of multiple optional embodiments, the following beneficial effects can be achieved according to the embodiment of the invention:

in the dehumidifier 10 of the embodiment of the present invention, the condenser 120 and the evaporator 130 are transversely arranged at intervals, and define an airflow channel therebetween, when the fan 140 works, the air can drive the airflow to flow from one side of the evaporator 130 to the condenser 120, and the condenser 120 is provided with the water cooling pipe 123. After the dehumidifier 10 enters the cooling and dehumidifying mode, the circulating cooling water may be introduced into the water cooling pipe 123, the heat exchange efficiency of the condenser 120 may be improved by the cooling effect of the cooling water, and the air flow flowing through the condenser 120 may be cooled. Thus, not only the cooling effect of the dehumidifier 10 is improved, but also the purposes of energy saving and consumption reduction are achieved.

Further, in the dehumidifier 10 of the embodiment of the present invention, the condensation pipe is of a sleeve type structure, the inner pipe 121 of the condensation pipe can be communicated with the water cooling pipe 123 for circulating and flowing cooling water, and the outer pipe 122 of the condensation pipe can be communicated with the refrigerant pipeline for circulating and flowing refrigerant. In this way, after the dehumidifier 10 enters the cooling and dehumidifying mode, the condenser 120 exchanges heat with the evaporator 130, and the refrigerant in the outer tube 122 of the condenser tube exchanges heat with the cooling water in the inner tube 121, so that the heat exchange efficiency of the condenser 120 can be further enhanced, and the cooling effect of the dehumidifier 10 is more remarkable.

Further, in the dehumidifier 10 of the embodiment of the present invention, the condensation pipe is of a sleeve type structure, the inner pipe 121 of the condensation pipe can be communicated with the refrigerant pipeline, and the outer pipe 122 of the condensation pipe can be communicated with the water cooling pipe 123. In this way, after the dehumidifier 10 enters the temperature-increasing dehumidification mode, the supply of the cooling water to the water-cooling pipe 123 is stopped, and at this time, the outer pipe 122 of the condensation pipe is not cooled, the outer pipe 122 may form an air heat insulation layer of the inner pipe 121, and the heat exchange efficiency between the condenser 120 and the evaporator 130 may be reduced by the heat insulation effect of the outer pipe 122, so that the temperature-increasing effect of the dehumidifier 10 in the temperature-increasing dehumidification mode is more remarkable.
