Description

Technical Field

[0001] This utility model relates to the field of high and low temperature rapid control technology, and in particular to a rapid heating and cooling high and low temperature cycling device. Background Technology

[0002] Rapid temperature change devices are widely used in various industries. The general working process is as follows: a certain temperature or constant temperature for a period of time, then a certain rate or a certain time to reach a low temperature, a certain temperature and a constant temperature for a period of time, and then a certain rate or a certain time to reach a high temperature again.

[0003] In general, rapid temperature change devices generate a certain amount of condensate when switching internal temperatures. This water remains in the insulation box and is reheated as the temperature changes. Repeatedly heating this water leads to energy waste. To improve energy efficiency, we propose a rapid heating and cooling high and low temperature circulation device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid heating and cooling high and low temperature cycling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A door is rotatably installed on the front side of the insulated box, and a back plate is fixedly installed on the rear side of the insulated box. An internal heating and cooling component and a dehumidification mechanism are arranged inside the insulated box. The dehumidification mechanism includes a supporting drain pipe that passes through to the outside of the back plate and is fixedly connected to the back plate. A water collection tank is connected to the upper side of the supporting drain pipe. An inverted cone air chamber is arranged above the water collection tank. An exhaust pipe and a vent pipe are respectively connected to both sides of the inverted cone air chamber. Both the exhaust pipe and the vent pipe pass through to the outside of the insulated box. An air pump is fixedly installed on the side wall of the insulated box, and the output end of the air pump is connected to the vent pipe.

[0007] Furthermore, an air intake pipe is connected and installed on the air pump inlet end, and the support drain pipe is set at an angle.

[0008] Furthermore, a number of connecting columns are fixedly connected between the inverted cone air cavity and the water collection tank.

[0009] Furthermore, the internal heating and cooling assembly includes several sets of evaporators and several sets of electric heating tubes, which are distributed alternately. The electric heating tubes are fitted with heat insulation grooves on their outer sides. An inner lining plate is fixedly installed on the inner side of the insulation box. The several sets of evaporators and several sets of electric heating tubes are fixedly installed between the inner side of the insulation box and the outer side of the inner lining plate.

[0010] Furthermore, a compressor, a refrigerant inlet equalizing pipe, and a refrigerant return equalizing pipe are fixedly installed on the side wall of the insulation box. A condenser is fixedly installed on the upper side of the insulation box. The compressor is connected to the condenser.

[0011] Furthermore, a temperature sensor is fixedly installed on the inner wall of the lining plate.

[0012] Furthermore, a handle and a controller are fixedly installed on the door, a window is opened through the door, double-layered vacuum transparent glass is installed on the inside of the window, and a heat insulation layer is provided on the outside of the exhaust pipe and the vent pipe.

[0013] Compared with related technologies, the rapid heating and cooling high and low temperature circulation device proposed in this utility model has the following beneficial effects:

[0014] In this invention, a rapid heating and cooling high and low temperature circulation device is provided. This device incorporates a dehumidification mechanism, which includes a supporting drain pipe, a water collection tank, an inverted cone air chamber, and an air pump. During heating in the insulation box, the air pump is simultaneously activated to inject flowing air into the inverted cone air chamber, thus providing ventilation and heat dissipation. Since the surface of the inverted cone air chamber is relatively stable and low inside the insulation box, water vapor inside the insulation box adheres to the surface of the inverted cone air chamber and accumulates as condensate. The accumulated condensate slides down the inclined surface of the inverted cone air chamber and drips into the water collection tank, subsequently being discharged from the supporting drain pipe. This avoids the repeated heating of condensate in the insulation box, preventing resource waste and improving the energy efficiency of this invention. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figure 1-5 A rapid heating and cooling high and low temperature circulation device includes an insulated box 1, a door 2 rotatably mounted on the front side of the insulated box 1, a back plate 3 fixedly mounted on the rear side of the insulated box 1, an internal heating and cooling component 7 and a dehumidification mechanism 8 arranged inside the insulated box 1; the dehumidification mechanism 8 includes a supporting drain pipe 81, which passes through to the outside of the back plate 3 and is fixedly connected to the back plate 3, a water collection tank 82 is connected to the upper side of the supporting drain pipe 81, an inverted cone air chamber 83 is arranged on the upper side of the water collection tank 82, an exhaust pipe 85 and a vent pipe 86 are respectively connected to the two sides of the inverted cone air chamber 83, both the exhaust pipe 85 and the vent pipe 86 pass through to the outside of the insulated box 1, an air pump 87 is fixedly mounted on the side wall of the insulated box 1, the output end of the air pump 87 is connected to the vent pipe 86, and a heat insulation layer is arranged on the outside of the exhaust pipe 85 and the vent pipe 86.

[0023] With the above-mentioned configuration, the heat insulation layer on the outside of the exhaust pipe 85 and the vent pipe 86 provides heat insulation for the exhaust pipe 85 and the vent pipe 86. As a result, when the exhaust pipe 85 and the vent pipe 86 are ventilated and dissipated, the temperature of the outer wall of the pipe is not affected, and the temperature of the outer wall is the same as that of the inner wall of the heat preservation box 1. This prevents water vapor from condensing and accumulating on the exhaust pipe 85 and the vent pipe 86 and dripping down, and allows the water vapor to be concentrated and condensed on the inverted cone air chamber 83.

[0024] In this method, a handle 4 and a controller 5 are fixedly installed on the door 2, and a window 6 is opened through the door 2. Double-layered vacuum transparent glass is installed on the inner side of the window 6.

[0025] By using the above method, double-layered vacuum transparent glass has thermal insulation properties.

[0026] In this configuration, an air intake pipe 88 is connected to the air inlet end of the air pump 87, and the drain pipe 81 is inclined.

[0027] With the above configuration, the air intake pipe 88 provides an air inlet for the air pump 87, and the support drain pipe 81 is set at an angle so that the water flow can be quickly discharged by the support drain pipe 81 after it gathers in the water collection tank 82.

[0028] In this configuration, a number of connecting columns 84 are fixedly connected between the inverted cone air cavity 83 and the water collection tank 82.

[0029] With the above-described configuration, the connecting column 84 provides support for the inverted cone air chamber 83.

[0030] In this method, the internal heating and cooling assembly 7 includes several sets of evaporators 72 and several sets of electric heating tubes 73, which are staggered. The electric heating tubes 73 are fitted with heat insulation grooves 71. An inner lining plate 9 is fixedly installed inside the insulation box 1. The several sets of evaporators 72 and several sets of electric heating tubes 73 are fixedly installed between the inner side of the insulation box 1 and the outer side of the inner lining plate 9. A temperature sensor 10 is fixedly installed on the inner wall of the inner lining plate 9. A compressor 11, a refrigerant input equalizing pipe 13, and a refrigerant return equalizing pipe 14 are fixedly installed on the side wall of the insulation box 1. A condenser pipe 12 is fixedly installed on the upper side of the insulation box 1. The compressor 11 is connected to the condenser pipe 12. The refrigerant input equalizing pipe 13 is connected to the inflow end of several sets of evaporators 72. The refrigerant return equalizing pipe 14 is connected to the outflow end of several sets of evaporators 72. The refrigerant return equalizing pipe 14 is connected to the compressor 11.

[0031] With the above setup, compressor 11 is started, drawing in low-pressure refrigerant gas. After compression, it becomes high-temperature, high-pressure refrigerant gas. The high-temperature, high-pressure refrigerant gas enters condenser 12 and releases heat to the surrounding environment (usually air) through the heat dissipation effect of condenser 12, causing the refrigerant gas to cool and condense into high-pressure liquid. The high-pressure liquid flows into refrigerant input equalization pipe 13 and is subsequently injected into each evaporator 72 simultaneously after throttling and pressure reduction. The low-temperature, low-pressure refrigerant liquid enters evaporator 72 and, with the heat inside the insulation box, quickly evaporates into low-temperature, low-pressure refrigerant gas, which then flows back into refrigerant return equalization pipe 14, forming a refrigeration cycle and lowering the temperature in insulation box 1.

[0032] The working principle of the rapid heating and cooling high and low temperature circulation device provided by this utility model is as follows:

[0033] When heating the insulation box is required, the heating element 73 is activated, and the air pump 87 is activated simultaneously. Air is injected into the inverted cone air chamber 83 through the vent pipe 86. The air in the inverted cone air chamber 83 is discharged through the exhaust pipe 85. The surface temperature of the inverted cone air chamber 83 is low, and water vapor inside the insulation box 1 will adhere to the surface of the inverted cone air chamber 83 to form condensate. The condensate drips down the inclined surface of the inverted cone air chamber 83 into the water collection tank 82 and is discharged outside the insulation box 1 through the support drain pipe 81, avoiding the waste of resources caused by repeated heating of condensate. When cooling is required, the compressor 11 is activated to draw in low-pressure refrigerant gas and compress it into high-temperature and high-pressure gas. After releasing heat in the condenser pipe 12, it cools and condenses into high-pressure liquid, which is then introduced into the refrigerant input equalization pipe 13. Subsequently, the high-pressure liquid is injected into each evaporator 72 after throttling and pressure reduction, absorbs heat from the insulation box 1 and evaporates into low-temperature and low-pressure gas, which flows back into the refrigerant return equalization pipe 14, completing the refrigeration cycle.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
