Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, and in particular to a refrigeration module. The utility model also relates to a semiconductor dehumidifier. Background Art

[0002] As people pay more and more attention to healthy living, dehumidifiers are rapidly becoming one of the indispensable home appliances in many families, with broad market prospects and market potential.

[0003] At present, the common semiconductor dehumidifier refrigeration modules on the market mainly include cooling fans, air duct front covers, heat dissipation aluminum blocks, semiconductor refrigeration plates, air duct rear covers, condensing aluminum blocks and other components. The heat dissipation aluminum block is close to the hot end surface of the semiconductor refrigeration plate, and the condensing aluminum block is close to the cold end surface of the semiconductor refrigeration plate. The cooling fan forces air to cool the heat dissipation aluminum block, and the heat released by the hot end surface of the semiconductor refrigeration plate is discharged to the outside of the machine on both sides through the air duct. At the same time, the surrounding air flows through the surface of the condensing aluminum block by natural circulation. When the temperature of the air drops below its dew point temperature, the water vapor in the air will condense on the surface of the condensing aluminum block, and then gather and flow into the water tank, thereby achieving the purpose of reducing the absolute water content in the air.

[0004] The current refrigeration module mainly relies on air convection generated by the cooling fan to draw air. The amount of air flowing through the surface of the condensing aluminum block per unit time is small, the dehumidification amount per unit time is limited, and the dehumidification efficiency is not high. Utility Model Content

[0005] In view of the technical problems in the prior art, the utility model provides a refrigeration module. On the basis of the existing refrigeration module, a condensing fan is added to force the air around the machine to flow through the surface of the condensing aluminum block through the condensing fan, thereby increasing the amount of air flowing through the surface of the condensing aluminum block per unit time, thereby achieving the purpose of increasing the dehumidification amount per unit time at a lower cost.

[0006] The technical solution includes a heat dissipation fan, a heat dissipation aluminum block, a semiconductor refrigeration plate and a condensation aluminum block. The heat dissipation aluminum block is close to the hot end surface of the semiconductor refrigeration plate, and the condensation aluminum block is close to the cold end surface of the semiconductor refrigeration plate. The heat dissipation fan is installed on the side of the heat dissipation aluminum block away from the hot end surface. The heat dissipation fan is used to blow air to cool the heat dissipation aluminum block. It also includes a condensation fan. The condensation fan is installed above the condensation aluminum block. Under the action of the condensation fan, the surrounding air flows through the surface of the condensation aluminum block to form condensed water.

[0007] Furthermore, a refrigeration module also includes an air guide cover, one end of which is connected to the air outlet of the condensing fan, and the other end of which is sleeved on the condensing aluminum block.

[0008] Furthermore, the air guide cover does not completely wrap the condensation aluminum block.

[0009] Beneficial effects:

[0010] 1. In the utility model, by setting a condensing fan, the surrounding air can be forced to flow through the surface of the condensing aluminum block, increasing the amount of air flowing through the surface of the condensing aluminum block per unit time, thereby achieving the purpose of increasing the dehumidification amount per unit time at a lower cost.

[0011] 2. In the utility model, the wind blown out by the condensing fan can be guided by the setting of the wind guide cover, thereby further increasing the amount of air flowing through the surface of the condensing aluminum block per unit time; by the setting that the wind guide cover does not completely wrap the condensing aluminum block, it is possible to ensure that the dried air flows out from both sides of the condensing aluminum block under the premise of guiding.

[0012] The utility model also provides a semiconductor dehumidifier, comprising any one of the above-mentioned refrigeration modules.

[0013] Furthermore, a semiconductor dehumidifier also includes a casing and a water tank, the casing is provided with a circulating air inlet, a heat dissipation air inlet and an air outlet, a water collecting plate is installed inside the casing, a refrigeration module and a water tank are respectively arranged above and below the water collecting plate, the condensing fan (5) is connected to the circulating air inlet, the water collecting plate is provided with a water hole connected to the water tank, and the condensed water flows into the water tank through the water hole.

[0014] Furthermore, the circulating air inlet is located at the top of the casing, the heat dissipation air inlet is located at the back of the casing, and the air outlet is located at both sides of the casing.

[0015] Furthermore, a filter is detachably installed in the heat dissipation air inlet.

[0016] Furthermore, a water collecting trough which is low in the middle and high around is provided on the top of the water collecting plate, and the water through hole is located in the middle of the water collecting trough and connects the water collecting trough and the water tank.

[0017] Furthermore, a semiconductor dehumidifier also includes a water level detection mechanism, which includes a magnetic switch, magnetic beads and a suspension block. A suspension basket is fixedly installed in the water tank, and the suspension basket is located on the side wall of the water tank near the top end. The magnetic switch is connected to the control system of the refrigeration module, and the magnetic switch is fixedly installed on the casing. The magnetic beads are fixedly installed on the suspension block, and the suspension block is slidably placed in the suspension basket. When there is no water in the water tank or the water level does not exceed the suspension basket, the suspension block does not move, the magnetic beads and the magnetic switch are attracted, the magnetic switch is closed, and the refrigeration module works. Otherwise, the suspension block moves with the water surface, the magnetic beads and the magnetic switch are separated, the magnetic switch is disconnected, and the refrigeration module does not work.

[0018] Furthermore, the water level detection mechanism also includes an alarm, and the alarm is connected to a control system. The control system controls whether the alarm sends an alarm signal according to the signal of the magnetic switch being opened or closed.

[0019] Beneficial effects:

Specifically, when the water tank is not installed or not installed in place, the magnetic beads and the magnetic switch are in a separated state. At this time, the magnetic switch is disconnected and the refrigeration module does not work. In addition, when the condensed water in the water tank exceeds the maximum water level of the water tank, the suspension block will drive the magnetic beads to move up and separate them from the magnetic switch. At this time, the magnetic switch is disconnected, the refrigeration module does not work, and the continued generation of condensed water is avoided. Through the setting of the alarm, the user can be reminded in time. BRIEF DESCRIPTION OF THE DRAWINGS
