Detailed Description
The embodiment provides a refrigerator, which can timely find out the internal water leakage condition of the refrigerator, avoid water leakage to threaten the use safety of a user and ensure clean environment, and promote the use experience of the user. Fig. 1 is a schematic overall structure of a refrigerator 100 according to an embodiment of the present invention, and fig. 2 is a schematic structure of a water leakage detecting device 130 in the refrigerator 100 according to an embodiment of the present invention. As shown in fig. 1 and 2, a refrigerator 100 may generally include: the case 110, the door 120, and the water leakage detecting device 130.
Wherein, the interior of the case 110 defines a storage space. The door 120 may be disposed on a front surface of the case 110 to close the storage space. The water leakage detecting device 130 may be disposed at the bottom of the case 110, and the water leakage detecting device 130 includes: the first and second wires 131 and 132 are configured to determine an internal water leakage condition of the refrigerator 100 by detecting a resistance between the first and second wires 131 and 132.
In the prior art, the refrigerator has internal water leakage, and the water leakage can have unpredictable results when flowing to the ground. For example, the use safety of the user is possibly threatened, in addition, when the water leakage condition is serious, a large amount of water is spread, the water possibly flows out of the area where the refrigerator is located, even the floor in the user home is damaged by infiltration, and the use experience of the user is seriously affected. The refrigerator 100 of the embodiment can detect all internal water leakage conditions by providing the water leakage detection device 130, because the water leakage detection device 130 at the bottom can be found in time as long as the interior of the refrigerator 100 leaks, and the water leakage detection device must pass through the bottom of the refrigerator 100. The water leakage can be effectively avoided, the use safety and the clean environment of the user are threatened, and the use experience of the user is improved.
In a specific embodiment, the water leakage detecting device 130 may further include: a third wire 133 and a fourth wire 134, and one end of the third wire 133 is connected to the first wire 131 and the other end is disconnected from the second wire 132; one end of the fourth wire 134 is connected to the second wire 132, and the other end is disconnected from the first wire 131. In other embodiments, one end of the third wire 133 may be connected to the second wire 132, and the other end may be disconnected from the first wire 131; one end of the fourth wire 134 is connected to the first wire 131, and the other end is disconnected from the second wire 132. That is, the third wire 133 and the fourth wire 134 ensure that one end is connected to the first wire 131 or the second wire 132 and the other end is disconnected, so that the first wire 131 and the second wire 132 are in an open state.
In fact, in the absence of internal water leakage, no water flows through the bottom of the refrigerator 100, and the first and second wires 131 and 132 are open-circuited, and the resistance therebetween is infinitely large. In case that the refrigerator 100 is leaked internally, water passes through the bottom of the refrigerator 100, and a path is formed between the first wire 131 and the second wire 132 due to the water having conductivity, having a specific resistance value, not infinity. Therefore, it is possible to effectively and accurately determine whether or not the refrigerator 100 has an internal water leakage by detecting the resistance value between the first wire 131 and the second wire 132.
As shown in fig. 2, in a preferred embodiment, the third wire 133 and the fourth wire 134 are each provided in plurality to form a mesh structure 135 together with the first wire 131 and the second wire 132. The third conductive wire 133 and the fourth conductive wire 134 are disposed at intervals, and the density of the mesh structure 135 is equal to or greater than a predetermined threshold. The third wire 133 and the fourth wire 134 are arranged at intervals, so that one side of the first wire 131 is separated from the third wire 133 and the fourth wire 134 in a connecting and disconnecting way, and one side of the second wire 132 is separated from the third wire 133 and the fourth wire 134 in a disconnecting and connecting way, so that a longer section of disconnection blank is avoided at the positions of the first wire 131 and the second wire 132.
The density of the mesh structure 135 is equal to or greater than a preset threshold value, and by setting the preset threshold value, the density of the mesh structure 135 can be ensured. The specific value of the preset threshold value can be set according to practical situations, for example, the magnitude of water leakage, the accuracy of water leakage detection and the like are considered. Through realizing the mesh structure 135 that density is great, combining third wire 133 and fourth wire 134 interval setting, avoid first wire 131 and second wire 132 department to have longer one section to break off the blank, can effectively avoid appearing leaking the condition of examining to leaking, effectively guarantee the whole operational reliability who detects leaking.
In addition, the water leakage detecting device 130 may further include: the substrate 136 is attached to the bottom of the case 110, and the substrate 136 is made of an insulating material. In one particular embodiment, the substrate 136 may be a PVC material, i.e., a polyvinyl chloride material. PVC is white powder with amorphous structure, has smaller branching degree, better mechanical property, tensile strength of about 60MPa and impact strength of 5-10 KJ/m 2 Has excellent dielectric properties. PVC is very widely used as a versatile plastic that has been the most productive worldwide.
In a preferred embodiment, the mesh structure 135 is entirely printed on the substrate 136. That is, the printing of the web 135 entirely on the substrate 136 may be accomplished in a printed circuit board-like process. A printed circuit board, also referred to as a printed circuit board (Printed circuit boards, PCB) is a provider of electrical connections for electronic components. The main advantage of using a printed circuit board is that wiring and assembly errors are greatly reduced, and the automation level and the production labor rate are improved. The advantage of printing the mesh structure 135 entirely on the substrate 136 in this embodiment is utilized to greatly increase the production efficiency.
In a more preferred embodiment, the area of the substrate 136 is the same as the bottom area of the refrigerator 100, and the first and second conductive lines 131 and 132 are disposed at two opposite edges of the substrate 136 such that the mesh structure 135 covers the bottom of the case 110. That is, on the basis of ensuring that the density of the mesh structure 135 is equal to or greater than the preset threshold, it is further ensured that the mesh structure 135 covers the bottom of the case 110. This makes it possible to form a passage between the first and second wires 131 and 132 in time through water flowing through the bottom of the refrigerator 100 when water leaks, so that the internal leakage of the refrigerator 100 can be found in any case.
It should be noted that the shape of the substrate 136 may be adapted to the shape of the bottom surface of the refrigerator 100. If the bottom surface of the refrigerator 100 is generally rectangular, as shown in FIG. 2, the substrate 136 may be rectangular to conform to the shape of the bottom surface of the refrigerator 100. In other embodiments, if the bottom surface of the refrigerator 100 is of other shapes, the substrate 136 may be provided in other shapes as long as it is adapted to the shape of the bottom surface of the refrigerator 100. This ensures that the area of the substrate 136 is the same as the bottom area of the refrigerator 100 to some extent. In addition to the successful efficiency of detecting water leakage and the production cost, the arrangement of redundant detection parts is avoided, and the substrate 136 can be prevented from exceeding the bottom surface of the refrigerator 100, so that the overall attractiveness of the refrigerator 100 is ensured.
As shown in fig. 2, the water leakage detecting device 130 may further include: the resistance sensor 137 is disposed between the first wire 131 and the second wire 132, and configured to detect a resistance value between the first wire 131 and the second wire 132. And, the water leakage detecting device 130 is further configured to: in the case where the resistance sensor 137 detects that the resistance value between the first wire 131 and the second wire 132 is equal to or less than the preset resistance threshold, it is determined that there is an internal water leakage condition of the refrigerator 100. The resistance sensor 137 may be any type of sensor as long as a resistance value can be detected. Specifically, the resistance sensor 137 may determine the type based on comprehensive consideration in terms of detection accuracy, volume size, service life, and the like.
Specifically, if the resistance sensor 137 detects that the resistance value between the first wire 131 and the second wire 132 is infinite and cannot detect a specific value, it is determined that the first wire 131 and the second wire 132 are in an open state, and no water flows through the bottom of the refrigerator 100, thereby determining that there is no internal water leakage of the refrigerator 100. If the resistance sensor 137 detects that the resistance value between the first wire 131 and the second wire 132 is less than or equal to the preset resistance threshold, it may be determined that the first wire 131 and the second wire 132 are in a communication state, and water flows through the bottom of the refrigerator 100, thereby determining that there is an internal water leakage condition of the refrigerator 100.
In a preferred embodiment, the refrigerator 100 may further include: and an alarm device configured to output alarm information to alert a user after determining that there is an internal water leakage condition of the refrigerator 100. Specifically, a display device 121 may be provided on the door 120 of the refrigerator 100 to output alarm information. I.e. the display device 121 may be used as an alarm device. The display device 121 may output voice information, video information, picture information, etc. to prompt the user that the refrigerator 100 has a water leakage phenomenon inside. In other embodiments, the alarm device may be a buzzer, and the buzzer outputs sound information to prompt the user that the refrigerator 100 leaks water.
In a specific embodiment, the interior of the case 110 may define a plurality of storage spaces, and the number and structure of the storage spaces may be configured according to requirements. Fig. 1 and 2 show the case of three storage spaces sequentially arranged from top to bottom, wherein each storage space may be respectively provided as a refrigerating space, a freezing space, a temperature changing space or a fresh keeping space. The interior of each storage space can be divided into a plurality of storage areas by a partition plate, and the storage areas are stored by utilizing racks or drawers.
The door 120 may be disposed at a front side of the case 110, so that a user can open or close the storage space of the refrigerator 100, and the door 120 is disposed corresponding to the storage space, i.e. each storage space corresponds to one or more doors 120. The door opening mode of the storage space can be pivoted to open, and drawer type opening can also be adopted to open so as to realize the drawer type storage space. In a specific embodiment, the door body of the refrigerating space is pivoted to open, and the door body of the freezing space is drawer-type to open.
The refrigerator 100 may further include: the refrigeration system may be a refrigeration cycle system including a compressor, a condenser, a throttle device, an evaporator, a refrigeration fan, and the like. Wherein the compressor can be installed in the compressor bin, and the evaporator and the refrigerating fan can be arranged in the cooling chamber. In another embodiment, the evaporator and the refrigeration fan may also be disposed within the supply air duct, which may then be considered a cooling chamber.
The refrigeration system provides different amounts of cold to the refrigerated space and the refrigerated space such that the temperatures within the refrigerated space and the refrigerated space are also different. Wherein the temperature in the refrigerated space is generally between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. The temperature in the refrigerated space is generally in the range of-22 ℃ to-14 ℃. The optimal storage temperatures of different kinds of foods are not the same, and thus the storage spaces suitable for storage are not the same. For example, fruit and vegetable foods are suitable for storage in a refrigerated space, while meat foods are suitable for storage in a frozen space.
A water pan can be arranged below the evaporator and used for receiving condensed water generated by the evaporator. The front section bottom wall and the rear section bottom wall of the water receiving disc are inclined planes which incline downwards along the directions of the front section bottom wall and the rear section bottom wall. The front section diapire and the back section diapire of water collector all have certain contained angle with the horizontal plane, can make the comdenstion water that the evaporimeter produced get into the water collector smoothly to can guarantee whole discharge, effectively guarantee the operational reliability of evaporimeter.
The bottom of the water pan may be provided with a drain opening below the evaporator. And the inclination of the bottom wall of the front section of the water receiving tray is larger than that of the bottom wall of the rear section, so that the water outlet is close to the front end of the evaporator in the horizontal direction. The external air can pass through the evaporator after entering the cooling chamber through the water outlet, and adverse phenomena such as frosting, icing and the like can not be directly formed on the air cooler.
It is emphasized that a heating wire may be provided at the evaporator for heating the evaporator to defrost the evaporator. And after the evaporator is normally heated for defrosting, the heating wire can fully melt residual ice cubes, so that the residual ice cubes are prevented from blocking the water outlet, the defrosting of the evaporator is ensured to be complete, and the refrigeration efficiency of the evaporator is effectively improved.
The interior of the case 110 may also define a compressor compartment disposed at the bottom of the case 110 and behind the cooling chamber. A condenser, a heat rejection fan, and a compressor may be disposed in the compressor compartment. In a specific embodiment, the refrigerator 100 may further include: the evaporation dish is arranged below the condenser, so that the moisture in the evaporation dish is evaporated by utilizing the heat of the condenser, and the moisture is taken away by the heat dissipation fan to fully dissipate heat.
The refrigerator 100 may further include: and one end of the drain pipe is connected with the drain outlet of the water receiving disc, and the other end of the drain pipe is communicated with the evaporation dish so as to transmit condensed water in the water receiving disc to the evaporation dish. Specifically, the drain pipe is placed in an inclined mode, one end of the drain pipe, which is connected with the drain outlet, is higher than the other end of the drain pipe, and an included angle between the drain pipe and the horizontal plane is larger than or equal to a preset angle. The inclined angle of the drain pipe is matched with the inclined surface angle of the water receiving disc, so that condensed water in the water receiving disc can be smoothly discharged.
Because the water receiving tray of the refrigerator in the prior art is affected by low temperature or the evaporator is affected by high temperature, the condition of aging cracking or breaking often occurs. The refrigerating space of the refrigerator is not cleaned for a long time, food scraps flow into the drain holes, the drain pipelines are blocked, and water after defrosting of the evaporator cannot be led into the water receiving tray. When the indoor temperature is too high, such as when the south enters a continuous high temperature period, the condensation process of frost gas on a condensation pipe of the refrigerator is accelerated, and water dripping is easy to become more serious. The various possible situations can lead to internal water leakage of the refrigerator, and the water leakage can have unpredictable effects on the ground. For example, the use safety of the user may be threatened, in addition, when the water leakage condition is serious, a large amount of water is spread, the water may flow out of the area where the refrigerator is located, and even the floor in the user's home is damaged by infiltration, so that the use experience of the user is affected.
The refrigerator 100 of the embodiment can effectively detect that condensed water and defrosting water in the water receiving tray cannot be normally discharged, and the water leakage phenomenon in the refrigerator 100 occurs.
