Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, and in particular to a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure. Background Technology

[0002] With social development and the improvement of people's living standards, the public is increasingly pursuing a healthy and comfortable indoor environment, especially air temperature and cleanliness. Traditional fresh air dehumidifiers have difficulty maintaining a constant air temperature when processing air, especially during the low temperature and high humidity season (plum rain season). The air temperature is very low after dehumidification, which makes the room too cold. Therefore, an electric heater needs to be added to the air outlet to ensure the indoor air temperature. Moreover, the dehumidifiers in the current technology do not recover the heat in the condenser to heat the fresh air, resulting in a certain amount of energy waste.

[0003] Therefore, a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure was designed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure.

[0005] The technical problem to be solved by this utility model is to provide a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure, which solves the problem of heat waste caused by the lack of a heat recovery device on the condenser of the existing dehumidifier.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure, comprising a dehumidification box, an air inlet slot, and an exhaust fan. Multiple air inlet slots are provided above the right side surface of the dehumidification box. An exhaust fan is installed through the left side surface of the dehumidification box. A water collection trough is installed through the center of the interior of the dehumidification box, and a drain pipe is installed through the bottom of the water collection trough. A coolant tank is fixedly installed at the bottom inner side of the dehumidification box. A delivery pump is installed on the side of the coolant tank. The drain end of the delivery pump is connected to a compressor via a pipe. A condenser is connected to the inner side of the compressor. An evaporator is connected to the right side of the condenser. A return pipe on the evaporator passes through the coolant tank.

[0007] Preferably, the condenser is located to the left of the evaporator, and both the condenser and the evaporator are located above the water collection tank.

[0008] Preferably, the drain pipe is L-shaped and extends through the right side surface of the dehumidification box. A rubber hose is fitted to the end of the drain pipe and is inserted into the sewer pipe.

[0009] Preferably, a first baffle is fixedly provided on the right side surface of the condenser, and a second baffle is fixedly provided on the left side surface of the condenser.

[0010] Preferably, the top horizontal height of the first baffle is equal to the top horizontal height of the condenser, and the bottom horizontal height of the first baffle is higher than the bottom horizontal height of the condenser.

[0011] Preferably, the bottom horizontal height of the second baffle is equal to the bottom horizontal height of the condenser, and the bottom horizontal height of the second baffle is lower than the top horizontal height of the condenser.

[0012] Preferably, an auxiliary heater is fixedly installed on the left side inside the dehumidification box.

[0013] Preferably, the auxiliary heater is located between the condenser and the exhaust fan.

[0014] Preferably, a temperature sensor is fixedly installed on the right side surface of the auxiliary heater, and a control switch for the auxiliary heater is installed inside the temperature sensor.

[0015] Preferably, dustproof nets are fixedly installed inside both the air inlet slot and the exhaust fan.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] 1. This utility model, by incorporating a condenser and an evaporator, dehumidifies the indoor environment. A pump draws gaseous coolant from the coolant tank to a compressor, which then delivers the coolant to the condenser for condensation. The condensation generates heat that is dissipated from the condenser. The condensed coolant is then transferred to the evaporator, where it vaporizes, absorbing heat and cooling itself. When the exhaust fan is activated, outside air enters through the air inlet. This air comes into contact with the cooled evaporator, causing water vapor to condense on its surface and drip into a collection tank, from where it is drained through a drain pipe. This process effectively dehumidifies the air. Furthermore, the heat radiated from the condenser as the air passes through it heats the dehumidified air, utilizing the heat from the condenser and reducing energy consumption.

[0018] 2. This utility model, by setting a first baffle and a second baffle, allows air to be dehumidified by the evaporator 8. The first baffle blocks the air, so that the dehumidified cold air can only flow in from the top and bottom of the condenser. The air flowing into the condenser is blocked by the second baffle and can only be discharged from the bottom of the second baffle. This increases the time that the air stays in the condenser, making it easier for the heat generated by the condenser 7 to be absorbed by the cold air, and further increasing the utilization of heat on the condenser.

[0019] 3. This utility model is equipped with an auxiliary heater. When the temperature sensor detects that the air temperature passing through the auxiliary heater is too low, the auxiliary heater is turned on by a control switch to heat the air, preventing the air temperature after dehumidification from being too low and ensuring a good user experience.

[0029] Example:

[0030] like Figures 1-6As shown, an embodiment of this utility model provides a variable frequency heat pump all-season fresh air dehumidifier with a condensation heat recovery structure, including a dehumidification box 1, an air inlet slot 2, and an exhaust fan 3. Multiple air inlet slots 2 are provided above the right side surface of the dehumidification box 1. An exhaust fan 3 is installed through the left side surface of the dehumidification box 1. A water collection trough 101 is installed through the center of the interior of the dehumidification box 1. A drain pipe 102 is installed through the bottom of the water collection trough 101. A coolant tank 4 is fixedly installed at the bottom of the inner side of the dehumidification box 1. A transfer pump 5 is installed on the side of the coolant tank 4. The drain end of the transfer pump 5 is connected to a compressor 6 through a pipe. A condenser 7 is connected to the inner side of the compressor 6. An evaporator 8 is connected to the right side of the condenser 7. A return pipe on the evaporator 8 passes through the coolant tank 4.

[0031] In this embodiment, the condenser 7 is located to the left of the evaporator 8, and both the condenser 7 and the evaporator 8 are located above the water collection tank 101, so that the water droplets condensed on the evaporator 8 can fall into the water collection tank 101 for collection and be discharged through the drain pipe 102.

[0032] In this embodiment, the drain pipe 102 is L-shaped and extends through the right side surface of the dehumidification box 1. A rubber hose is fitted to the end of the drain pipe 102 and is inserted into the sewer pipe to facilitate the water in the water collection tank 101 to flush the drain pipe 102 into the sewer pipe.

[0033] By incorporating a condenser 7 and an evaporator 8, during indoor dehumidification, the gaseous coolant in the coolant tank 4 is pumped to the compressor 6 by the delivery pump 5. The compressor then delivers the gaseous coolant to the condenser 7 for condensation, turning the coolant into a liquid state. The heat generated during condensation is dissipated from the condenser 7. The condensed coolant in the condenser 7 is then delivered to the evaporator 8, where it vaporizes the coolant, absorbing heat and cooling the evaporator 8. When the exhaust fan 3 is turned on, outside air enters through the air inlet slot 2. The air comes into contact with the cooled evaporator 8, causing water vapor in the air to condense into water droplets on the surface of the evaporator 8 and drip into the water collection tank 101, which is then discharged through the drain pipe 102, achieving the effect of dehumidifying the air. As the air passes through the condenser 7, the heat emitted from the condenser 7 heats the dehumidified air, thus utilizing the heat from the condenser 7 and reducing energy consumption.

[0034] In this embodiment, a first baffle 701 is fixedly provided on the right side surface of the condenser 7, and a second baffle 702 is fixedly provided on the left side surface of the condenser 7.

[0035] In this embodiment, the top horizontal height of the first baffle 701 is equal to the top horizontal height of the condenser 7, and the bottom horizontal height of the first baffle 701 is higher than the bottom horizontal height of the condenser 7, so that the dehumidified air can only flow in from the lower right side of the condenser 7.

[0036] In this embodiment, the bottom horizontal height of the second baffle 702 is equal to the bottom horizontal height of the condenser 7, and the bottom horizontal height of the second baffle 702 is lower than the top horizontal height of the condenser 7, so that the air in the condenser 7 can only be discharged from the upper left side of the condenser 7.

[0037] With the first baffle 701 and the second baffle 702 installed, after the air is dehumidified by the evaporator 8, the first baffle 701 blocks the air, so that the dehumidified cold air can only flow into the condenser 7 from the top and bottom. The air flowing into the condenser 7 is blocked by the second baffle 702 and can only be discharged from the bottom of the second baffle 702. This increases the time that the air stays in the condenser 7, making it easier for the heat generated by the condenser 7 to be absorbed by the cold air, and further increasing the utilization of heat on the condenser 7.

[0038] In this embodiment, an auxiliary heater 9 is fixedly installed on the left side inside the dehumidification box 1.

[0039] In this embodiment, the auxiliary heater 9 is located between the condenser 7 and the exhaust fan 3, which facilitates heating the dehumidified air.

[0040] In this embodiment, a temperature sensor is fixedly installed on the right side surface of the auxiliary heater 9, and the control switch used by the auxiliary heater 9 is installed inside the temperature sensor.

[0041] By incorporating an auxiliary heater 9, when the temperature sensor detects that the air temperature passing through the auxiliary heater 9 is too low, the auxiliary heater 9 is turned on via a control switch to heat the air, preventing the dehumidified air temperature from being too low and ensuring a good user experience.

[0042] In this embodiment, dustproof nets are fixedly installed in both the air inlet slot 2 and the exhaust fan 3 to prevent impurities from entering the dehumidification box 1.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
