Description

Technical Field

[0001] The invention relates to the field of dehumidifiers, and in particular to a dehumidifier structure capable of continuously preventing temperature rise. Background Art

[0002] Dehumidifiers are used to control the humidity in a specified space, and dehumidify by cooling and condensing the moisture in the air. When using a dehumidifier, since the dehumidifier is in the use space, according to the principle of heat conservation, the heat generated by the compressor and fan will continue to be dissipated into the use space, which will eventually cause the temperature of the space to become higher and higher, affecting the customer's use effect and experience.

[0003] In order to solve this problem, the Chinese patent with the prior art application number 202021502725.8: A dehumidifier anti-temperature rise structure discloses a dehumidifier structure composed of a compressor, an evaporator, two condensers, a solenoid valve, a centrifugal fan, and a heat dissipation fan, one of which is set outdoors, and heat is dissipated by adding an outdoor condenser to prevent temperature rise. However, when the dehumidifier is reversed to defrost, the outdoor condenser cannot dissipate heat and condense, so continuous temperature rise prevention cannot be achieved. Summary of the invention

[0004] The purpose of the present invention is to provide a dehumidifier structure capable of continuously preventing temperature rise, so as to solve the problem that the dehumidifiers in the prior art cannot continuously prevent temperature rise during defrosting.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A dehumidifier structure capable of continuously preventing temperature rise comprises a compressor, an evaporator, a first condenser, a second condenser and a solenoid valve, wherein the first condenser is arranged indoors, a centrifugal fan is arranged on the air outlet side of the first condenser, the second condenser is arranged outdoors, a heat dissipation fan is arranged on the air inlet side of the second condenser, the exhaust end of the compressor is connected to the air inlet end of the first condenser through a pipeline, the air outlet end of the compressor is also connected to the air inlet end of the solenoid valve through a pipeline, the air outlet end of the solenoid valve is connected to the air inlet end of the second condenser through a pipeline, the air outlet end of the evaporator is connected to the air inlet end of the compressor through a pipeline, and the throttling device is also included, and the first one-way valve is connected to the air outlet end of the compressor. A one-way valve rectifier bridge is formed by a first one-way valve, a second one-way valve, a third one-way valve and a fourth one-way valve, the one-way valve rectifier bridge having a common air inlet end, a common air outlet end and two middle ends, the air outlet end of the first condenser is connected to an middle end of the one-way valve rectifier bridge through a pipeline, the air outlet end of the second condenser is connected to the common air outlet end of the one-way valve rectifier bridge through a pipeline, a pipeline is led out between the air outlet end of the second condenser and the common air outlet end of the one-way valve rectifier bridge and is connected to the air inlet end of the throttling device, the air outlet end of the throttling device is connected to the common air inlet end of the one-way valve rectifier bridge through a pipeline, and the air inlet end of the evaporator is connected to the other middle end of the one-way valve rectifier bridge through a pipeline.

[0007] Furthermore, in the one-way valve rectifier bridge, the outlet ends of the first one-way valve and the second one-way valve are connected through a pipeline to form a common outlet end, the inlet ends of the third one-way valve and the fourth one-way valve are connected through a pipeline to form a common inlet end, the inlet end of the first one-way valve and the outlet end of the third one-way valve are connected through a pipeline to form an intermediate end, and the inlet end of the second one-way valve and the outlet end of the fourth one-way valve are connected through a pipeline to form another intermediate end.

[0008] Furthermore, a fifth one-way valve is provided between the outlet end of the second condenser and the outlet end connected to the one-way valve rectifier bridge. The air inlet end of the second one-way valve is connected to the outlet end of the second condenser through a pipeline, and the outlet end of the fifth one-way valve is connected to the outlet end connected to the one-way valve rectifier bridge through a pipeline.

[0009] Furthermore, the throttling device adopts a capillary tube.

[0010] Furthermore, the air inlet and outlet pipes of the throttling device are respectively connected to filters.

[0011] Further, the compressor is connected to the first condenser, the solenoid valve, and the evaporator through a four-way reversing valve, wherein:

[0012] The exhaust end of the compressor is connected to the first valve port of the four-way reversing valve through a pipeline, and a pipeline is led out between the exhaust end of the compressor and the first valve port of the four-way reversing valve and connected to the air inlet end of the solenoid valve, the second valve port of the four-way reversing valve is connected to the air inlet end of the first condenser through a pipeline, the third valve port of the four-way reversing valve is connected to the air outlet end of the evaporator through a pipeline, and the fourth valve port of the four-way reversing valve is connected to the air inlet end of the compressor through a pipeline.

[0013] In the present invention, the first to fourth one-way valves form a one-way valve rectifier bridge. No matter from which front-rectifier inlet or outlet of the one-way valve rectifier bridge the refrigerant flows in or out, the one-way valve rectifier bridge can always allow the refrigerant to pass through the throttling device in the same direction.

[0014] When defrosting, the one-way valve rectifier bridge automatically adjusts the direction of the refrigerant flowing through the throttling device, so that the refrigerant flowing through the second condenser is introduced into the throttling device and enters the system. At this time, the second condenser still discharges heat to the outdoors, which can effectively prevent indoor temperature from rising.

[0015] Therefore, the present invention can prevent the dehumidifier from continuously working and causing the indoor temperature to rise. At the same time, it can continue to prevent the temperature from rising when the dehumidifier is switching to defrost, thereby ensuring the customer's use effect and experience.

[0019] 3. The present invention has a simple structure, is easy to manufacture, and is safe and reliable;

[0020] 4. The present invention has a wide application range and can be widely used in dehumidifier equipment that can prevent temperature rise. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, the dehumidifier structure with sustainable temperature prevention of the present invention is actually improved on the basis of Chinese patent application number 202021502725.8: a dehumidifier temperature prevention structure, and a one-way valve rectifier bridge is added.

[0024] The present invention comprises a compressor 1, an evaporator 2, a first condenser 3.1, a second condenser 3.2, a solenoid valve 4, a throttling device 5, a four-way reversing valve 6, and a one-way valve rectifier bridge composed of a first one-way valve 7.1, a second one-way valve 7.2, a third one-way valve 7.3, and a fourth one-way valve 7.4, and further comprises a fifth one-way valve 7.5.

[0025] The first condenser 3.1 is arranged indoors, and a centrifugal fan 8 is arranged on the air outlet side of the first condenser 3.1. The second condenser 3.2 is arranged outdoors, and a heat dissipation fan 9 is arranged on the air inlet side of the second condenser 3.2. The exhaust end of the compressor 1 is connected to the first valve port of the four-way reversing valve 6 through a pipeline, a pipeline is led out between the exhaust end of the compressor 1 and the first valve port of the four-way reversing valve 6 and connected to the air inlet end of the solenoid valve 4, the air outlet end of the solenoid valve 4 is connected to the air inlet end of the second condenser 3.2 through a pipeline, and the second valve port of the four-way reversing valve 6 is connected to the air inlet end of the first condenser 3.1 through a pipeline.

[0026] In the one-way valve rectifier bridge, the outlet ends of the first one-way valve 7.1 and the second one-way valve 7.2 are connected together through a pipeline to form a common outlet end, the inlet ends of the third one-way valve 7.3 and the fourth one-way valve 7.4 are connected together through a pipeline to form a common inlet end, the inlet end of the first one-way valve 7.1 and the outlet end of the third one-way valve 7.3 are connected through a pipeline to form an intermediate end, and the inlet end of the second one-way valve 7.2 and the outlet end of the fourth one-way valve 7.4 are connected through a pipeline to form another intermediate end.

[0027] The gas outlet of the first condenser 3.1 is connected to the middle end between the second check valve 7.2 and the fourth check valve 7.4 in the check valve rectifier bridge through a pipeline, the gas outlet of the second condenser 3.2 is connected to the gas inlet of the fifth check valve 7.5 through a pipeline, the gas outlet of the fifth check valve 7.5 is connected to the common gas outlet of the check valve rectifier bridge through a pipeline, the lead-out pipeline between the gas outlet of the fifth check valve 7.5 and the common gas outlet of the check valve rectifier bridge is connected to the gas inlet of the throttling device 5 through the first filter 10.1, the throttling device 5 adopts a capillary tube, the gas outlet of the throttling device 5 is connected to the common gas inlet of the check valve rectifier bridge through a pipeline with a second filter 10.2, and the middle end between the first check valve 7.1 and the third check valve 7.3 in the check valve rectifier bridge is connected to the gas inlet of the evaporator 2 through a pipeline.

[0028] The gas outlet end of the evaporator 2 is connected to the third valve port of the four-way reversing valve 6 through a pipeline, and the fourth valve port of the four-way reversing valve 6 is connected to the gas inlet end of the compressor 1 through a pipeline.

[0029] The cooling fan 9 blows air to dissipate heat to the second condenser 3.2, accelerates the condensation and cooling of the refrigerant in the second condenser 3.2, and strengthens the heat exchange between the second condenser 3.2 and the outside air. The solenoid valve 4 controls whether the refrigerant in the dehumidifier can enter the second condenser 3.2. It can control the flow direction of the refrigerant in the system as required, control the heat discharge path, and achieve the effect of controlling the temperature. The fifth one-way valve 7.5 is one-way, and the refrigerant in the second condenser 3.2 is introduced into the air inlet end of the throttling device 5, while preventing the refrigerant from reversely entering the second condenser 3.2, which plays the role of making the refrigerant one-way, so that the refrigerant can only flow from the air outlet end of the second condenser 3.2 to the air outlet end, and the reverse direction is automatically cut off. The one-way valve rectifier bridge allows the refrigerant to enter the throttling device 5 in the same direction. When the dehumidifier is reversing to defrost, the one-way valve rectifier bridge automatically adjusts the direction of the refrigerant flowing through the throttling device 5, so that the refrigerant flowing through the second condenser 3.2 is introduced into the throttling device 5 and enters the system. At this time, the second condenser 3.2 still discharges heat to the outdoors to prevent the indoor temperature from rising.

[0030] The working process of the present invention is as follows:

[0031] (1) When the dehumidifier continues to work, causing the indoor temperature to rise, the solenoid valve 4 and the heat dissipation fan 9 are opened respectively.

[0032] (2) A portion of the high-temperature and high-pressure gas refrigerant compressed by the compressor 1 enters the second condenser 3.2 through the solenoid valve 4.

[0033] (3) The heat dissipation fan 9 dissipates heat, cools and condenses the refrigerant entering the second condenser 3.2.

[0034] (4) The refrigerant after cooling and condensation enters the system through the fifth one-way valve 7.5 and the one-way valve rectifier bridge and enters the air inlet end of the dehumidifier throttling device, merges with the refrigerant in the first condenser 3.1, and then enters the dehumidification system.

[0035] (5) According to the principle of heat conservation, part of the heat in the refrigerant is dissipated to the air on the outdoor side through the second condenser 3.2, thereby reducing the heat of the air on the indoor side, thereby preventing the temperature on the indoor side from continuing to rise.

[0036] (6) When the indoor temperature drops, the solenoid valve 4 and the cooling fan 9 are closed respectively. At this time, all the refrigerant enters the first condenser 3.1, and the heat in the refrigerant is not dissipated to the outside through the second condenser 3.2, thus maintaining the indoor heat and preventing the indoor temperature from dropping further.

[0037] (7) When the dehumidifier is reversed to defrost, the one-way valve rectifier bridge automatically adjusts the direction of the refrigerant flowing through the throttling device 5, so that the refrigerant flowing through the second condenser 3.2 is introduced into the throttling device 5 and enters the system, thereby continuously preventing the temperature on the indoor side from rising when the dehumidifier is defrosting.

[0038] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the protection scope of the present invention.
