Most refrigeration equipment manufacturers can test the water evaporation capacity of the evaporation dish of the new type of refrigeration equipment at present, and water needs to be injected into the evaporation dish or defrosting water in the evaporation dish needs to be extracted in the test. In the test, a mechanical arm and other devices are generally used, so that if water is injected into the evaporation dish or defrosting water in the evaporation dish is pumped by a manual mode, a great potential safety hazard exists. Meanwhile, when the evaporation capacity of the water in the evaporation pan is tested, the water can be possibly carried out in a more extreme testing environment, so that the manual operation is also very inconvenient.

The utility model provides a testing device for refrigeration equipment, which can be used for injecting water into an evaporation dish or extracting defrosting water in the evaporation dish under the condition that a safety distance is kept between the testing device and a mechanical arm, so that potential safety hazards are reduced. Meanwhile, compared with manually injecting water into or extracting defrosting water from the evaporation dish, the utility model has the advantages of more convenient, quick and accurate test.

As shown in fig. 1 to 6, the embodiment of the present disclosure provides a testing apparatus for a refrigeration device including a sensing assembly 10, a water storage assembly 20, and a pipe 30. The detection assembly 10 can be placed in an evaporation pan and comprises a stabilizing block 101 and a first sensor 103 arranged on the stabilizing block 101; the water storage assembly 20 comprises a water pumping device 201 and a water storage tube 202 communicated with the water pumping device 201; the first end of the pipeline 30 is arranged in the stabilizing block 101 to be relatively fixedly arranged in the evaporation pan, and the second end is communicated with the water pumping device 201 to inject water into or pump water from the evaporation pan. Wherein the detection assembly 10 is disposed in the evaporation pan, the first sensor 103 is operable to detect the water level in the evaporation pan.

Specifically, the water pumping device 201 is a two-way water pump, and includes a first water pumping port communicated with the pipeline 30 and a second water pumping port communicated with the water storage tube 202, and the water pumping device 201 can pump water in the evaporation pan into the water storage tube 202 or pump water in the water storage tube 202 into the evaporation pan. The first end of the pipeline 30 penetrates through the stabilizing block 101 and is placed in the evaporation pan together with the stabilizing block 101 to be communicated with the evaporation pan and the first water pumping port of the water pumping device 201, and the arrangement can prevent the first end of the pipeline 30 from shifting in the evaporation pan, so that water pumping or water injection quantity is affected. The first sensor 103 is a water level sensor, and is disposed on a side wall surface or a lower end surface of the stabilizing block 101, and is used for detecting the water level in the evaporation pan.

Optionally, stabilizer block 101 is made of a corrosion resistant material such as stainless steel to avoid corrosion of stabilizer block 101 in extreme environments or water, and to increase the useful life of stabilizer block 101.

As shown in fig. 5 and 6, in some embodiments, the stabilizer block 101 is provided with mounting holes 1011 penetrating the upper and lower end surfaces; the first end of the pipeline 30 is penetrated from the upper end surface to the lower end surface of the stabilizing block 101, and the port of the first end is lower than the lower end surface of the stabilizing block 101.

Specifically, the mounting hole sets up in the center department of stable piece, and the first terminal surface of the first stable piece of port of mounting hole and first end is worn to locate to the first end of pipeline, so set up can prevent that stable piece from interfering the pipeline and draw water.

In some implementations, the stabilizer block 101 has a circular cross-section, and the mounting hole 1011 is disposed concentrically with the stabilizer block 101.

In other practical applications, the cross section of the stabilizing block 101 is square, and the center of the mounting hole 1011 coincides with the center line of the square.

Optionally, a second sensor is provided within the water reservoir 202, which can be used to detect the water level within the water reservoir 202.

In some embodiments, the test device for a refrigeration device further includes an alarm device. The warning device is disposed on the water storage component 20 and is electrically connected to the first sensor 103. Wherein, when the first sensor 103 detects that the evaporation pan is in a water-free state and/or the water level is higher than a preset water level, the warning device can be triggered.

Specifically, the first sensor 103 includes one or more signal output ends, and the warning device is electrically connected with the signal output ends of the first sensor 103, and when the first sensor 103 detects that the evaporation dish is in a water-free state, a water-free signal can be transmitted to the warning device to trigger the warning device, and the warning device can give an alarm to remind a user, so that the user can take measures in time. When the first sensor 103 detects that the water level in the evaporation pan is higher than the preset water level, a high water level signal can be transmitted to the warning device to trigger the warning device, so that potential safety hazards caused by water overflow in the evaporation pan are avoided. Similarly, the second sensor includes one or more signal outputs, and the warning device is electrically connected to the signal outputs of the second sensor, and is triggered when the second sensor detects that the water storage tube 202 is in a water-free state or a high water level state.

As shown in fig. 4, the testing device for a refrigeration apparatus described above optionally further includes a display device 50. The display device 50 is disposed on the water storage assembly 20 and electrically connected to the signal output terminals of the first sensor 103 and the second sensor. The first sensor 103 and the second sensor can respectively convert water level parameters in the evaporation pan and the water storage tube 202 into electric signals in real time and transmit the electric signals to the display device 50, and the display device 50 can display the water levels in the evaporation pan and the water storage tube 202 in real time after receiving the electric signals. By the arrangement, the water level in the evaporation pan and the water storage tube 202 can be observed more conveniently and intuitively by an operator.

In an actual application scenario, the preset water level can be properly adjusted according to the size of the evaporating dish, which is not limited herein.

In some practical applications, the warning device may be an alarm that may draw the attention of the user, such as a sound emitting device and/or a light emitting device.

As shown in fig. 3, in some embodiments, the end face of the first end of the conduit 30 is provided as a bevel. Wherein the angle of the inclined plane is greater than or equal to the first angle theta 1 and less than or equal to the second angle theta 2.

Specifically, the bevel angle of the first end of the pipe 30 is a preset angle θ, which is greater than or equal to 2 ° and less than or equal to 10 °. For example, the preset angle θ may be 2 °, 4 °, 6 °, 8 °, or 10 °.

It will be appreciated that in the test of the evaporation capacity of the water in the evaporation pan, the closer the first end of the pipe 30 is to the bottom of the evaporation pan, the smaller the residual amount of water in the evaporation pan is, and the more accurate the detection result is. Setting the first end of the pipe 30 to be inclined can prevent the pipe 30 from being blocked by the bottom surface of the evaporation pan due to the fact that the first end of the pipe 30 is too close to the bottom surface of the evaporation pan.

In some embodiments, the diameter of the conduit 30 is greater than the diameter of the mounting bore 1011.

Specifically, the diameter of the mounting hole 1011 may be 5/6, 4/5 or 3/4 of the diameter of the pipe 30. So set up, when pipeline 30 wears to locate mounting hole 1011, be interference fit between pipeline 30 and the mounting hole 1011, can avoid pipeline 30 to break away from with stabilizing block 101 and influence the test result, as shown in fig. 3.

It can be understood that, generally, in the testing process, the pipeline 30 penetrating into the refrigeration equipment can reach 1 meter, if the pipeline 30 is in interference fit with the mounting hole 1011, the detection assembly 10 can be directly lifted up by the pipeline 30 and taken out from the refrigeration equipment after the testing is completed, so that the convenience of operation is improved.

As shown in fig. 3, in some embodiments, the lower end surface of the stabilizing block 101 is provided with a support block 102 such that the port of the first end of the tube 30 is disposed lower than the lower end surface of the stabilizing block 101 and can be a set distance from the bottom wall of the evaporation pan.

Specifically, the volume of the support block 102 is smaller than the volume of the stabilizing block 101, and when the detection assembly 10 is disposed in the evaporation pan, water can flow to the pipe 30 through the gaps between the support block 102. The height of the supporting block 102 is greater than or equal to the length of the first end of the pipeline 30 exposing the lower end face of the stabilizing block 101, so that deformation caused by contact between the first end of the pipeline 30 and the bottom of the evaporating dish can be avoided, and the water pumping or water injection efficiency is reduced.

Alternatively, the bottom surface of the stabilizing block 101 is provided with a plurality of support blocks 102, and the plurality of support blocks 102 are symmetrically disposed.

Specifically, symmetrically disposing the plurality of support blocks 102 on the bottom surface of the stabilizer block 101 may increase the stability of the support blocks 102.

In some practical applications, the number of the supporting blocks 102 is three, one supporting block 102 is disposed at a midpoint of a first edge of the bottom surface of the stabilizing block 101, and the other two supporting blocks 102 are symmetrically disposed at a second edge of the bottom surface of the stabilizing block 101. Wherein the first edge is disposed opposite to the second edge, as shown in fig. 5.

In other practical applications, the number of the supporting blocks 102 is four, two supporting blocks 102 are symmetrically arranged at the first edge of the bottom surface of the stabilizing block 101, and the other two supporting blocks 102 are symmetrically arranged at the second edge of the bottom surface of the stabilizing block 101. Wherein the first edge is disposed opposite to the second edge as shown in fig. 6.

In some embodiments, the testing apparatus for a refrigeration device described above further comprises a control assembly. The control assembly is electrically connected with the water pumping device 201 and can be used for controlling the water pumping device 201 to be opened or closed.

It is understood that the control assembly includes a chip with logic capability and a circuit corresponding to the chip, and the control assembly includes one or more signal inputs and one or more signal outputs.

In one specific application, the testing device further includes a control switch 40, as shown in FIG. 4. The control switch 40 is electrically connected with the signal input end of the control component, the pumping device 201 is electrically connected with the signal output end of the control component, and an operator can control the pumping device 201 to pump water in the water storage tube 202 into the evaporation pan, pump water in the evaporation pan into the water storage tube 202 or close the pumping device 201 through the control switch 40.

Optionally, the control switch 40 includes a first pumping switch, a second pumping switch and a stop switch, the first pumping switch controls the pumping device 201 to pump water in the water storage tube 202 into the evaporation pan, the second pumping switch controls the pumping device 201 to pump water in the evaporation pan into the water storage tube 202, and the stop switch controls the closing of the pumping device 201.

In another specific application, the first sensor 103 is electrically connected to a signal input terminal of a control assembly, and the control assembly controls the water pumping device 201 to be closed according to the detected water level information in the evaporating dish by the first sensor 103. Similarly, the control assembly controls the water pumping device 201 to be closed according to the detected water level information in the water storage tube 202 by the second sensor.

In some implementations, an operator controls the pumping device 201 to pump water in the water storage tube 202 into the evaporation dish through the first pumping switch. If the second sensor detects that the water level in the water storage barrel 202 is lower than the preset water level, the detection signal can be transmitted to the control component, and the control component can control the water pumping device 201 to be closed after receiving the water storage barrel 202 anhydrous signal so as to avoid the water pumping device 201 from idling, thereby prolonging the service life of the water pumping device 201; or, if the first sensor 103 detects that the water level in the evaporation pan is higher than the preset water level, the detection signal can be transmitted to the control component, and the control component can control the water pumping device 201 to be closed after receiving the evaporation pan high water level signal so as to avoid water overflow in the evaporation pan.

In other implementations, the operator controls the pumping device 201 to pump water from the evaporation dish into the water storage tube 202 via the second pumping switch. If the first sensor 103 detects that the water level in the evaporation pan is lower than the preset water level, a detection signal can be transmitted to the control component, and the control component can control the water pumping device 201 to be closed after receiving the water-free signal of the evaporation pan so as to avoid the water pumping device 201 from idling, thereby prolonging the service life of the water pumping device 201; or, if the second sensor detects that the water level in the water storage tube 202 is higher than the preset water level, the detection signal can be transmitted to the control component, and the control component can control the water pumping device 201 to be closed after receiving the high water level signal of the water storage tube 202 so as to avoid water overflow in the water storage tube 202.

In some embodiments, the conduit 30 is provided in a telescoping configuration.

Specifically, the conduit 30 is a flexible hose having a length greater than or equal to 2 meters and less than or equal to 4 meters when the conduit 30 is extended to a maximum length, for example, the maximum length of the conduit 30 may be 2 meters, 2.5 meters 3 meters, 3.5 meters, or 4 meters. The arrangement can enable operators and equipment such as a mechanical arm to keep enough safety distance, and potential safety hazards are avoided.

In some embodiments, the water withdrawal device 201 and the water storage cartridge 202 are of unitary construction.

Specifically, the second water pumping port of the water pumping device 201 and the water storage tube 202 are integrated, so that the manufacturing process can be simplified, and meanwhile, the leakage condition of the water pumping device 201 when water is injected into the water storage tube 202 or water in the water storage tube 202 is pumped can be avoided.

In some embodiments, the test device for a refrigeration appliance further includes a power source. The power supply is electrically connected with the water pumping device 201, can be used for supplying power to the water pumping device 201, and is provided with a waterproof structure.

Specifically, the power source may be provided independently, or may be provided to the water storage assembly 20. When the power supply is arranged on the water storage component 20, a waterproof structure such as a waterproof box or a waterproof coating layer is arranged on the outer side of the power supply.

In practical applications, the detection assembly 10 is placed in the evaporation pan, and an operator can control the pumping device 201 to pump water in the water storage tank 202 into the evaporation pan or pump water in the evaporation pan into the water storage tank 202 through the control assembly at a remote place, and then observe the water levels in the evaporation pan and the water storage tank 202 in real time through the display device 50 arranged on the water storage assembly 20. When the water level in the evaporation pan and/or the water storage tube 202 is higher than a preset water level or in a water-free state, the warning device can warn to prompt an operator to take relevant measures, and the control assembly can also automatically close the water pumping device 201.

Compared with a manual water pumping mode, the utility model reduces the potential safety hazard in the testing process and improves the convenience and accuracy of the test.
