the utility model provides an anti-blocking drainage device which comprises a drainage pipe 1, a heating component 2 and a temperature detection component, wherein the heating component 2 can heat water flowing into the drainage pipe 1, and the temperature detection component is positioned in the drainage pipe 1 and can monitor the temperature in the drainage pipe 1 in real time.

The heating assembly 2 can heat the drain pipe 1, so that water flowing into the drain pipe 1 is effectively prevented from icing in the process of flowing out of the drain pipe 1, and the drain pipe 1 is prevented from being blocked due to icing. The temperature detection component can convey the temperature data acquired through the temperature measurement part to relevant equipment, and whether the heating component 2 is started or not is determined by acquiring the temperature condition of the drain pipe 1 and judging the relation between the temperature data and zero, so that the drain pipe 1 is prevented from being blocked due to untimely heating of the heating component 2.

In order to ensure that the temperature data obtained at the temperature sensing assembly is sufficiently accurate, as an alternative embodiment, the temperature sensing assembly is provided to include a water temperature sensing assembly 3 for sensing the temperature of the water flowing into the drain pipe 1 and a wall temperature sensing assembly 4 for sensing the temperature of the wall of the drain pipe 1. Therefore, the temperature of the drain pipe 1 can be comprehensively judged according to the temperature condition of the water temperature detection assembly 3 and the temperature condition of the wall temperature detection assembly 4, so that the working condition of the heating assembly 2 can be controlled more accurately.

The heating unit 2 may be disposed at various positions, and may be disposed in the drain pipe 1 or may be disposed outside the drain pipe 1.

The present embodiment will be described by taking an example in which the heating element 2 is located outside the drain pipe 1.

As shown in fig. 1, the heating unit 2 is located outside the upper end of the drain pipe 1. In order to ensure that heat generated by the operation of the heating assembly 2 can be effectively transferred to the drain pipe 1, the heating assembly 2 is arranged to be in contact with the drain pipe 1, and heat conduction can be conducted between the heating assembly and the drain pipe in a contact mode.

Specifically, the heating assembly 2 is sleeved outside the upper end of the drain pipe 1 and can be connected with the drain pipe 1 in a threaded connection manner.

Generally, the drain pipe 1 is used for being connected with the water receiving tray 5 for receiving defrosting water, a drain hole is arranged on the water receiving tray 5, and the drain pipe 1 is connected with the water receiving tray 5 through the drain hole so as to drain water falling into the water receiving tray 5. Because above-mentioned heating element 2 and drain pipe 1 threaded connection, consequently heating element 2 also is located near the wash port, when its during operation, except being used for heating drain pipe 1, can also carry out heating treatment to water tray 5 department to avoid the ice-cube to get into drain pipe 1 through the wash port as far as in, play preliminary effect that avoids drain pipe 1 to block up. Meanwhile, the temperature of the drain pipe 1 heated by the heating component 2 can be raised to a certain extent, and the water in the drain pipe 1 can be effectively prevented from freezing due to low temperature.

The heating component is connected with corresponding control equipment and power supply equipment through a wiring terminal 7.

In this embodiment, in order to ensure drainage efficiency while minimizing the space occupation of the drain pipe 1 as much as possible, as an alternative embodiment, a funnel-shaped water collecting member 11 is formed at one end of the drain pipe 1 near the water receiving tray 5.

In addition, in order to enhance the firmness of connection between the drain pipe 1 and the water receiving disc 5, the outer peripheral side of the upper edge of the water collecting piece 11 can be outwards protruded to form a supporting plate type structure which can play a good role in supporting the bottom wall of the water receiving disc 5, and the whole supporting plate type structure is of a hollow annular structure, and the water collecting piece 11 is located in the supporting plate type structure and integrally formed with the supporting plate.

In addition to the water collecting member 11 and the pallet structure, the water discharging pipe 1 further includes a water pipe line located below the water collecting member 11, and the water pipe line and the water collecting member 11 may be of a separate type or an integral type.

To further solve the problem of blockage of the drain pipe 1, to avoid larger ice cubes or other impurities from entering the drain pipe 1, as an alternative embodiment, a filter assembly 6 is further provided in the drain pipe 1, the filter assembly 6 being capable of filtering water flowing into the drain pipe 1.

Specifically, the filtering component 6 is located at the joint of the water collecting piece 11 and the water delivery pipeline.

The arrangement of the above-described temperature detection assembly is explained below:

as shown in fig. 1-2, the temperature sensing assembly includes a water temperature sensing assembly 3 and a wall temperature sensing assembly 4. In order to ensure the accuracy of the detected data, the temperature measuring part of the water temperature detecting assembly 3 is arranged below the filtering assembly 6 and is not directly contacted with the water discharging pipe 1. In the same way, the temperature measuring part of the wall temperature detecting assembly 4 is arranged on the wall of the water delivery pipe, and in the embodiment, the temperature measuring part of the wall temperature detecting assembly 4 is arranged on the outer wall of the water delivery pipe.

In order to reduce the influence of the heating unit 2 on the detection data at the wall temperature detecting unit 4 as much as possible, in this embodiment, the temperature measuring part of the wall temperature detecting unit 4 is disposed on the water pipe.

Specifically, the temperature measuring part of the wall temperature detecting component 4 is located below the temperature measuring part of the water temperature detecting component 3, or the middle part of the water conveying pipeline of the temperature measuring part of the wall temperature detecting component 4 may be set.

It can be understood that under the cooperation of the above components, the device can determine the opening and closing time of the heating component 2 by acquiring the water temperature in the water drain pipe 1 and the temperature of the water drain pipe 1, thereby effectively avoiding the situation of icing and blocking at the water drain device, ensuring that the corresponding water drain equipment can still normally perform water drain operation in the outdoor low-temperature environment, and further ensuring that the corresponding unit can normally operate.

Example 2:

the embodiment provides an anti-blocking drainage method applying the anti-blocking drainage device, as shown in fig. 3, comprising the following steps:

step S1: acquiring an outdoor environment temperature t;

step S2: when the outdoor ambient temperature t is less than 0 ℃, the heating assembly 2 is activated.

In general, when the outdoor ambient temperature t is 0 ℃ or higher than 0 ℃, the inside of the drain pipe 1 is not frozen, and thus, it is not necessary to heat it; when the outdoor environment temperature t is lower than 0 ℃, the water discharge pipe 1 is extremely easy to freeze due to the fact that part of the structure of the water discharge pipe 1 is located outside the equipment and is influenced by the operation of the equipment, and therefore the water discharge pipe 1 needs to be heated by the heating component 2.

It should be noted that the above-mentioned acquisition of the outdoor ambient temperature t requires the passage of other temperature-sensing elements than those described above.

In order to achieve the energy-saving effect, the heating component 2 is prevented from working with high power for a long time, meanwhile, the drain pipe 1 is ensured not to be blocked due to icing all the time, and the working conditions of the heating component 2 under different conditions are required to be adjusted:

specifically, the heating component 2 is a heating element with adjustable heating power. In use, it has at least two different modes of operation, for example, a heating mode and a thermal insulation mode.

As an alternative embodiment, the temperature threshold t is obtained _x The temperature threshold t _x Greater than 0 ℃;

when the temperature detected by the temperature detection component does not exceed the temperature threshold t _x When the heating assembly 2 is adjusted to be in the heating mode.

Alternatively, when the temperature detected by the temperature detection assembly is higher than the temperature threshold t _x At this time, the heating assembly 2 is adjusted to be in the heat retaining mode.

Specifically, the temperature detected at the water temperature detecting unit 3 is set to be t ₁ The temperature detected at the wall temperature detection assembly 4 is t ₂ T is as described above ₁ And t ₂ Are all greater than t _x . In general, t ₁ ＞t ₂ ＞t _x 。

The temperature threshold t _x The acquisition mode of (a) is as follows:

temperature threshold t _x The length of the drain pipe 1 and the outdoor environment temperature t can be calculated according to the two parameters and by combining the corresponding coefficients.

Since the actual length of the drain pipe 1 may be affected by the installation situation, in the present embodiment, only the outdoor environment temperature t versus the temperature threshold t is considered _x The length of the drain pipe 1 is 1-2 m according to the conventional length.

Specifically, when the outdoor environment temperature t is lower, the temperature difference between the indoor and outdoor is larger, and the corresponding temperature threshold t _x Is high, i.e. the temperature threshold t _x There is a negative correlation with the outdoor ambient temperature t.

It can be appreciated that through the above-mentioned technical scheme, can control the operational aspect of heating element 2 according to outdoor temperature condition, guarantee through the temperature of control drain pipe 1 department that the water in the drain pipe 1 can remain liquid throughout the drainage process, effectively avoid drain pipe 1 to freeze.
