Description

[0002] When operating in low-temperature environments, electrical equipment such as air conditioning heat pump systems and heat pump water heaters are prone to frost formation on their heat source-side heat exchangers. When frost accumulates to a certain degree on the heat source heat exchanger, it is necessary to defrost it and drain the resulting water. During the defrosting process, the melted frost flows into a drain pan and is discharged through a drainpipe. Due to the low ambient temperature, ice easily forms in the drain pan, which can clog the drainpipe and affect the unit's normal operation. In severe cases, this can even damage the fan blades and the unit, leading to equipment failure and downtime.

[0003] To address this issue, the traditional approach is to heat the water tray. This is done by placing a heating pipe on the tray to prevent it from freezing. However, in extremely low outdoor temperatures, the drain pipe may freeze and become clogged, preventing it from draining properly.

[0004] Therefore, in order to solve the above problems, it is necessary to develop an anti-blocking drainage device, an anti-blocking drainage method and an electrical appliance having the same, which can ensure that the drain pipe can drain normally in a low temperature environment.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

[0041] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly.

Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0042] Example 1:

[0043] The present invention provides an anti-blocking drainage device, which includes three parts: a drain pipe 1, a heating component 2 and a temperature detection component. The heating component 2 can heat the water flowing into the drain pipe 1, and the temperature measuring part of the temperature detection component is located in the drain pipe 1, and can monitor the temperature in the drain pipe 1 in real time.

[0044] The heating component 2 can heat the drain pipe 1, thereby effectively preventing the water flowing into the drain pipe 1 from freezing during its outflow through the drain pipe 1, thereby preventing the drain pipe 1 from clogging due to freezing. The temperature detection component can transmit the temperature data obtained by the temperature measurement unit to relevant equipment. By obtaining the temperature of the drain pipe 1 and judging the relationship between the temperature data and zero, it determines whether to activate the heating component 2, thereby preventing the drain pipe 1 from clogging due to untimely heating by the heating component 2.

[0045] To ensure that the temperature data obtained by the temperature detection component is sufficiently accurate, as an optional embodiment, the temperature detection component in this embodiment includes a water temperature detection component 3 for detecting the temperature of water flowing into the drain pipe 1 and a wall temperature detection component 4 for detecting the temperature of the wall of the drain pipe 1. Therefore, the temperature of the drain pipe 1 can be comprehensively determined based on the temperature conditions at the water temperature detection component 3 and the temperature conditions at the wall temperature detection component 4, thereby achieving more precise control over the operation of the above-mentioned heating component 2.

[0046] The heating component 2 can be arranged in various positions. It can be set inside the drain pipe 1 or outside the drain pipe 1.

[0047] This embodiment is described by taking the example that the heating component 2 is located outside the drain pipe 1 .

[0048] like Figure 1 As shown, the heating component 2 is located outside the upper end of the drain pipe 1. In order to ensure that the heat generated by the heating component 2 can be effectively transferred to the drain pipe 1, the heating component 2 is set in contact with the drain pipe 1, and heat conduction can be carried out between the two by contact.

[0049] Specifically, the heating component 2 is sleeved on the outer side of the upper end of the drain pipe 1 and can be connected to the drain pipe 1 by a threaded connection.

[0050] Generally speaking, drain pipe 1 is connected to a water pan 5 that receives defrost water. The water pan 5 is provided with a drain hole, through which drain pipe 1 connects to the water pan 5, draining water that falls into the water pan 5. Because the heating assembly 2 is threadedly connected to drain pipe 1 and is located near the drain hole, when operating, it not only heats drain pipe 1 but also heats the water pan 5, thereby minimizing ice from entering drain pipe 1 through the drain hole and initially preventing blockage of drain pipe 1. Furthermore, the temperature of drain pipe 1 heated by the heating assembly 2 is also elevated, effectively preventing the water in drain pipe 1 from freezing due to low temperatures.

[0051] The heating components are connected to corresponding control devices and power supply devices via the wiring terminals 7 .

[0052] In this embodiment, in order to ensure drainage efficiency and minimize the space occupied by the drainage pipe 1, as an optional implementation, a funnel-shaped water collecting member 11 is formed at one end of the water receiving pipe close to the water receiving tray 5.

[0053] In addition, in order to enhance the firmness of the connection between the drain pipe 1 and the water collecting pan 5, the outer peripheral side of the upper edge of the above-mentioned water collecting member 11 can be arranged to bulge outward and form a support plate structure that can better support the bottom wall of the water collecting pan 5. The support plate structure is a hollow annular structure as a whole, and the water collecting member 11 is located in the support plate structure and is integrally formed with the support plate.

[0054] In addition to the water collecting member 11 and the supporting plate structure, the drain pipe 1 further includes a water supply pipeline located below the water collecting member 11 . The water supply pipeline and the water collecting member 11 may be a separate structure or an integrated structure.

[0055] In order to further solve the problem of blockage of the drain pipe 1 and prevent large ice cubes or other debris from entering the drain pipe 1 , as an optional embodiment, a filter component 6 is further provided in the drain pipe 1 , and the filter component 6 can filter the water flowing into the drain pipe 1 .

[0056] Specifically, the filter assembly 6 is located at the connection between the water collecting member 11 and the water delivery pipeline.

[0057] The arrangement of the above temperature detection components is described below:

[0058] like Figure 1-2 As shown, the temperature detection assembly includes a water temperature detection assembly 3 and a wall temperature detection assembly 4. To ensure the accuracy of the detection data, the temperature measurement portion of the water temperature detection assembly 3 is located below the filter assembly 6 and does not directly contact the drain pipe 1. Similarly, the temperature measurement portion of the wall temperature detection assembly 4 is located on the wall of the water supply pipe. In this embodiment, the temperature measurement portion of the wall temperature detection assembly 4 is located on the outer wall of the water supply pipe.

[0059] In order to minimize the influence of the heating component 2 on the detection data of the wall temperature detection component 4, in this embodiment, the temperature measurement part of the wall temperature detection component 4 is located on the water supply pipeline.

[0060] Specifically, the temperature measuring portion of the wall temperature detection component 4 is located below the temperature measuring portion of the water temperature detection component 3 , or the temperature measuring portion of the wall temperature detection component 4 can also be located in the middle of the water pipeline.

[0061] It can be understood that with the cooperation of the above components, the device can determine the timing of turning on and off the above heating component 2 by obtaining the water temperature in the drain pipe 1 and the temperature of the drain pipe 1, thereby effectively avoiding ice blockage in the drainage device, ensuring that the corresponding drainage equipment can still perform drainage operations normally in a low-temperature outdoor environment, and thus ensuring that the corresponding unit can operate normally.

[0062] Example 2:

[0063] This embodiment provides an anti-blocking drainage method using the above-mentioned anti-blocking drainage device, such as Figure 3 As shown, the following steps are included:

[0064] Step S1: Obtain outdoor ambient temperature t;

[0065] Step S2: When the outdoor ambient temperature t is less than 0°C, start the heating component 2.

[0066] Generally speaking, when the outdoor ambient temperature t is 0℃ or higher than 0℃, no ice will form in the drain pipe 1, so it does not need to be heated. However, when the outdoor ambient temperature t is lower than 0℃, since part of the structure of the drain pipe 1 is located outside the equipment and is affected by the operation of the equipment, ice is very likely to form in the drain pipe 1, so the heating component 2 is required to heat it.

[0067] It should be noted that the acquisition of the outdoor ambient temperature t requires other temperature sensing elements besides those mentioned above.

[0068] In order to achieve energy saving, avoid long-term high-power operation of the heating component 2, and ensure that the drain pipe 1 is never blocked by ice, it is necessary to adjust the working conditions of the heating component 2 under different conditions:

[0069] Specifically, the heating assembly 2 is a heating element with adjustable heating power. When in use, it has at least two different working modes, for example, a heating mode and a heat preservation mode.

[0070] As an optional implementation, obtain the temperature threshold t x , the temperature threshold t x Greater than 0℃;

[0071] When the temperature detected by the temperature detection component does not exceed the temperature threshold t x , adjust the heating component 2 to be in the heating mode.

[0072] As an optional embodiment, when the temperature detected by the temperature detection component is higher than the temperature threshold t x , adjust the heating component 2 to be in the keep warm mode.

[0073] Specifically, the temperature detected by the water temperature detection component 3 is set to t1, and the temperature detected by the wall temperature detection component 4 is set to t2. Both t1 and t2 are greater than t x Generally speaking, t1>t2>t x .

[0074] The above temperature threshold t x The way to obtain is as follows:

[0075] Temperature threshold t xIt is related to the length of the drainage pipe 1 and the outdoor ambient temperature t, and can be calculated based on the above two parameters in combination with the corresponding coefficients.

[0076] Since the actual length of the drainage pipe 1 may be affected by the installation conditions, in this embodiment, only the effect of the outdoor ambient temperature t on the temperature threshold t is considered. x In order to avoid the influence of the above-mentioned drainage pipe, the length of the drainage pipe 1 is set at a conventional length of 1 to 2 meters.

[0077] Specifically, when the outdoor ambient temperature t is lower, the temperature difference between indoor and outdoor is greater. Correspondingly, the temperature threshold t x The higher the value, that is, the temperature threshold t x There is a negative correlation between the outdoor ambient temperature t.

[0078] It can be understood that through the above technical solution, the working condition of the heating component 2 can be controlled according to the outdoor temperature conditions, and the temperature at the drain pipe 1 can be controlled to ensure that the water in the drain pipe 1 can always remain liquid during the discharge process, effectively preventing the drain pipe 1 from freezing.
