[0025] For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0026] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Furthermore, it should be understood that although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other. For example, a first display may be referred to as a second display, and similarly a second display may also be referred to as a first display, which does not deviate from the scope of protection of this application.

[0028] The utility model embodiment provides a test box, such as Figure 1 As shown, it includes a box body 1, a water level sensor 2 and a temperature sensor 3 arranged in the box body 1, the box body 1 is open upward and includes a bottom wall 11 away from the opening and a side wall 12 perpendicular to the bottom wall 11, the water level sensor 2 is vertically arranged in the box body 1, and one end of the water level sensor 2 is in contact with the bottom wall 11; the temperature sensor 3 is arranged in the box body 1 and is located at the bottom of the box body 1.

[0029] One end of the water level sensor 2 is in contact with the bottom wall 11, and the water level sensor 2 is vertically arranged in the box body 1, and can accurately sense the liquid level of the water in the box body 1. The side wall 12 of the box body 1 is perpendicular to the bottom wall 11, so that the cross section of the box body 1 is always consistent. The area of ​​the cross section of the box body 1 is calculated in advance, and the volume of the water in the box body 1 can be obtained by measuring the liquid level of the water in the box body 1 through the water level sensor 2.

[0030] For example, the standard volume of the test box is 500 ml of water at a standard temperature of 60°C, and when the test box is used for low-temperature defrosting tests, the opening size of the test box body 1 is usually required to be 600 cm 2 , the error is 60cm 2 The opening size of the box body 1 is generally 540-660cm 2The box body 1 is usually set to be a square box with a length of 25 cm and a width of 24 cm. The height of the box body 1 does not exceed 5 cm, so that the water in the box body 1 will not reduce the evaporation efficiency due to the height of the box body 1 being too high, or evaporate too quickly due to the height of the box body 1 being too low. One end of the water level sensor 2 is in contact with the bottom wall 11, and the liquid level height can be detected when there is water in the box body 1. Under the aforementioned size of the box body 1, the water level sensor 2 detects that the liquid level height is 0.83 cm, which means that the water volume meets the standard.

[0031] It should be noted here that although the water level sensor 2 and the temperature sensor 3 are both arranged in the box body 1, the volume of the water level sensor 2 and the temperature sensor 3 are relatively small, and the standard water volume of the test box during testing allows a certain error. On the basis of 500ml of water volume, there can be an error of 50ml above and below. Therefore, the influence of the water level sensor 2 and the temperature sensor 3 on the measurement of the water volume in the box body 1 can be ignored.

[0032] The temperature sensor 3 is arranged at the bottom of the box body 1. On the one hand, it can be in contact with water to avoid temperature error. On the other hand, the temperature can be directly measured when there is water in the box body 1.

[0033] Preferably, the temperature sensor 3 is disposed at the bottom of the bottom wall 11 or the bottom of the side wall 12. Figure 1 In this embodiment, the temperature sensor 3 is arranged at the center of the bottom wall 11 of the box body 1. When the user adds water to the box body 1, he usually pours water towards the center of the box body 1. The poured water contacts the temperature sensor 3 at the first time, and the real-time temperature data is obtained.

[0034] The temperature sensor 3 is arranged on the bottom wall 11 so that it can contact the water in the box body 1 earlier than the temperature sensor 3 is arranged on the bottom of the side wall 12. If the temperature sensor 3 is arranged on the bottom of the side wall 12, there will be errors in the installation, and the distance between the temperature sensor 3 and the bottom wall 11 of the box body 1 may be greater than the liquid level of the water in the box body 1 at the standard volume, so that the temperature sensor 3 cannot directly contact the water, and there will be errors in the temperature measurement.

[0035] Furthermore, the test box provided in the embodiment of the utility model is also provided with a first display 4, a second display 5, and a first wire 6 connected to the first display 4 and a second wire 7 connected to the second display 5. The first display 4 is connected to the water level sensor 2 through the first wire 6, and the second display 5 is connected to the temperature sensor 3 through the second wire 7, so that the liquid level of the water in the box body 1 measured by the water level sensor 2 can be displayed on the first display 4, and the temperature of the water in the box body 1 detected by the temperature sensor 3 can be displayed on the second display 5.

[0036] The first display 4 and the second display 5 are both arranged on the outside of the side wall 12, that is, the first display 4 and the second display 5 are both arranged on the side of the side wall 12 away from the water. On the one hand, it can prevent water from pouring on the first display 4 and / or the second display 5, or water from splashing on the first display 4 and / or the second display 5 when adding water into the box body 1, which may easily cause the first display 4 and / or the second display 5 to be damaged by contact with water; on the other hand, it can facilitate the user to observe the liquid level height and the real-time temperature of the water in the box body 1 in real time during the pouring process, so as to make adjustments.

[0037] Preferably, in this embodiment, the cross section of the box body 1 is in the direction, and the first display 4 and the second display 5 are arranged on the same side wall 12, which is more conducive to observation.

[0038] Of course, the cross-section of the box body 1 can also be circular or in other shapes. It is preferred to arrange the first display 4 and the second display 5 on the same side wall 12 or adjacent side walls 12 so that the first display 4 and the second display 5 face the same direction as much as possible, or the angle difference between the directions of the first display 4 and the second display 5 is small. If the cross-section of the box body 1 is circular, the first display 4 and the second display 5 are arranged as close as possible so that the angle difference between the directions of the first display 4 and the second display 5 is small.

[0039] Furthermore, the number displayed on the first display 4 may be the liquid level of the water in the box body 1, or a chip may be installed in the first display 4 to multiply the liquid level of the water in the box body 1 by the pre-calculated cross-sectional area of ​​the box body 1 to convert it into volume. Displaying the result in terms of volume is more conducive to users judging the amount of water.

[0040] Furthermore, the fonts displayed on the first display 4 include three colors, namely red, green and blue. When the water volume in the box body 1 meets the preset water volume, the first display 4 displays green fonts; when the water volume in the box body 1 is lower than the preset water volume, the first display 4 displays blue fonts; when the water volume in the box body 1 is higher than the preset water volume, the first display 4 displays red fonts.

[0041] Green is usually used as a color to indicate "pass", "OK", etc. When the amount of water in the box body 1 just meets the preset amount of water, the font color on the first display 4 turns green to remind the user that the amount of water in the box body 1 has met the requirement; red is usually used as a warning color. When the amount of water in the box body 1 exceeds the preset amount of water, the font color on the first display 4 turns red to warn the user and inform the user that the amount of water in the box body 1 exceeds the preset amount of water. Before the amount of water in the box body 1 meets the requirement, the font on the first display 4 is a relatively gentle blue.

[0042] Furthermore, the fonts displayed on the second display 5 also include three colors, namely red, green and blue. When the water temperature in the box body 1 meets the preset water temperature, the second display 5 displays green fonts; when the water temperature in the box body 1 is lower than the preset water temperature, the second display 5 displays blue fonts; when the water temperature in the box body 1 is higher than the preset water temperature, the second display 5 displays red fonts.

[0043] Similarly, when the water temperature in the box body 1 just meets the preset water temperature, the font on the second display 5 turns green to remind the user that the water temperature in the box body 1 has met the requirement; and when the water temperature in the box body 1 exceeds the preset water temperature, the font color on the second display 5 turns red to warn the user that the water temperature in the box body 1 exceeds the preset water temperature. Before the water temperature in the box body 1 meets the requirement, the font on the second display 5 is a relatively gentle blue.

[0044] Changing the font color to indicate the water volume and / or water temperature in the box body 1 under different conditions can assist the user in obtaining information about the water volume and / or water temperature in the box body 1. The naked eye has a higher degree of color discrimination than numbers, and can obtain corresponding information more quickly and accurately.

[0045] In addition, the first display 4 is also provided with a first signal light 41 and a second signal light 42. When the water volume in the box body 1 just meets the preset water volume, the first signal light 41 displays green and the second signal light 42 is turned off; when the water volume in the box body 1 does not meet the preset water volume (lower or higher than the preset water volume), the second signal light 42 displays red and the first signal light 41 is turned off. The second display 5 is also provided with a third signal light 51 and a fourth signal light 52. When the water temperature in the box body 1 just meets the preset water temperature, the third signal light 51 displays green and the fourth signal light 52 is turned off; when the water temperature in the box body 1 does not meet the preset water temperature (lower or higher than the preset water temperature), the fourth signal light 52 displays red and the third signal light 51 is turned off.

[0046] The aforementioned settings regarding the font color change and the signal light on the first display 4 and the second display 5 can be set either one of them or both at the same time.

[0047] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0048] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
