DETAILED DESCRIPTION

[0039] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] In the description of the present utility model, it should be understood that the wording "comprising" used in the present utility model specification refers to the presence of the features, integers, steps, operations, parts / components and / or assemblies, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts / components, assemblies and / or their groups. It should be understood that when we say that a part / component is "connected" to another part / component, it can be directly connected to the other part / component, or there can be intermediate parts / components. The wording "and / or" used here includes all or any unit and all combinations of one or more associated listed items.

[0041] As a common appliance in daily life, refrigerators are now widely used. Users can store food in refrigerators to prevent food from spoiling.

[0042] In this embodiment, the refrigerator includes a box body 1, a door body 2 and a shelf 3.

[0043] The box body 1 is used to form the overall appearance of the refrigerator. The box body 1 is roughly in the shape of a rectangular frame. The top of the box body 1 and the bottom of the box body 1 are opposite ends. From the top of the box body 1 to the bottom of the box body 1 is the height direction of the box body 1, the left side of the box body 1 and the right side of the box body 1 are opposite sides, from the left side of the box body 1 to the right side of the box body 1 is the width direction of the box body 1, the front side of the box body 1 and the back side of the box body 1 are opposite sides, and from the front side of the box body 1 to the back side of the box body 1 is the thickness direction of the box body 1.

[0044] A refrigerating chamber 11 is provided inside the box body 1, and the refrigerating chamber 11 is used to place goods. An opening 12 connected to the refrigerating chamber 11 is provided on one side of the box body 1, and the opening 12 is provided toward the front side of the box body 1. The refrigerating chamber 11 can be in a refrigerating temperature environment, a freezing temperature environment, or a normal temperature environment. A door body 2 is provided at the opening 12 of the box body 1, and the door body 2 is arranged in a straight plate shape at the front side of the box body 1. The door body 2 can be connected to the box body 1 in an openable and closable manner to open or close the refrigerating chamber 11.

[0045] The shelf 3 is disposed in the refrigerating chamber 11 and / or the inner side of the door 2 for storing items.

[0046] It can be understood that the refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed in the box 1, and the refrigeration system is used to provide cold air to the refrigeration room 11; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device and a refrigerant. Each component is distributed at different positions of the box 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and is cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0047] The air supply system is installed in the box 1 to provide power for the flow of cold air. The air supply system generally includes a fan and a guide cavity. In some embodiments, the air inlet end of the guide cavity is arranged close to the fan, and the air outlet end of the guide cavity is arranged away from the fan. In other embodiments, the air outlet end of the guide cavity is arranged close to the fan, and the air inlet end of the guide cavity is arranged away from the fan. The fan drives the air in the guide cavity, and the evaporator is correspondingly arranged in the guide cavity. The cold air cooled by the evaporator flows along the guide cavity through the driving part of the fan, and the cold air enters the cold storage room 11 to perform a cooling operation on the cold storage room 11.

[0048] Based on this, Figures 1 to 10 As shown, the utility model relates to a refrigerator, comprising:

[0049] The box body 1 has a refrigerating chamber 11 therein, and an opening 12 connected to the refrigerating chamber 11 is formed on one side of the box body 1.

[0050] The door body 2 is hinged to the box body 1 to open or close the opening 12.

[0051] The shelf 3 is arranged on the inner side of the refrigerating chamber 11 and / or the door body 2.

[0052] The detection device 4 includes a fixed seat 41, a movable seat 42, an elastic reset member 43, a first contact switch 44 and a controller. The fixed seat 41 is placed on the shelf 3. The movable seat 42 is arranged on the fixed seat 41 and can move in the height direction relative to the fixed seat 41. The movable seat 42 is used for placing the water storage member 100. The elastic reset member 43 is arranged between the fixed seat 41 and the movable seat 42. The first contact switch 44 is arranged on the fixed seat 41 and is located below the movable seat 42. The first contact switch 44 is electrically connected to the controller.

[0053] When the water level of the water storage member 100 is greater than a preset water level, the movable seat 42 can be pressed downward to press the first contact switch 44; when the water level of the water storage member 100 is less than the preset water level, the elastic reset member 43 pushes the movable seat 42 upward to disengage from the first contact switch 44.

[0054] In the present invention, the detection device 4 is installed on the shelf 3 of the refrigerator. The detection device 4 is used for placing the water storage member 100 and detecting the water level of the water storage member 100. Specifically, the water storage member 100 is placed on the movable seat 42. When the water level of the water storage member 100 is greater than the preset water level, the weight of the water storage member 100 can overcome the elastic force of the elastic reset member 43, press the movable seat 42 to move downward, and finally contact the contact of the first contact switch 44, so that the first contact switch 44 can be turned on. 44 sends a signal to the controller to reflect that there is enough water in the water storage part 100. When the water level in the water storage part 100 is lower than the preset water level, the elastic force of the elastic reset part 43 can offset the gravity of the water storage part 100, so that the movable seat 42 is separated from the first contact switch 44, thereby reflecting that the water storage part 100 is in a state of lack of water. Therefore, when the refrigerator of the present application detects the water level of the water storage part 100, there is no need to use a liquid level sensor for detection, thereby reducing equipment costs and making the detection method more reliable.

[0055] In this embodiment, the fixed seat 41 includes a first bottom plate 411 and a first side plate 412, the first side plates 412 are provided on the four sides of the upper part of the first bottom plate 411, an accommodating cavity 413 is formed between the four first side plates 412 and the first bottom plate 411, the elastic reset member 43 and the first contact switch 44 are both provided on the first bottom plate 411, the movable seat 42 is provided in the accommodating cavity 413, and the four sides of the movable seat 42 are close to the four first side plates 412 one by one.

[0056] The fixed seat 41 includes a first bottom plate 411 and a first side plate 412, and an accommodating cavity 413 is formed between the four first side plates 412 and the first bottom plate 411, and the movable seat 42 is arranged in the accommodating cavity 413, and the four sides of the movable seat 42 are close to the four first side plates 412 in a one-to-one correspondence, so that the fixed seat 41 can guide the movable seat 42, allowing the movable seat 42 to move stably in the height direction without deviation, thereby ensuring the detection of the water storage component 100.

[0057] Preferably, the elastic return member 43 is a return spring, the lower end of the return spring is connected to the first bottom plate 411 , and the upper end of the return spring abuts against the bottom of the moving seat 42 .

[0058] By setting the return spring, when the movable seat 42 moves downward under the action of the gravity of the water storage component 100, the movable seat 42 can compress the return spring. When the movable seat 42 is not affected by the gravity of the water storage component 100 or the water level in the water storage component 100 is lower than the preset water level, the return spring can push the movable seat 42 to move upward, so that the movable seat 42 is disengaged from the first contact switch 44, thereby realizing the function of detecting the water level in the water storage component 100.

[0059] Furthermore, a limiting column 414 is provided on the first bottom plate 411 , and the lower end of the reset spring is sleeved on the outer side of the limiting column 414 , thereby fixing the position of the reset spring to ensure that the reset spring can stably abut against the bottom of the moving seat 42 .

[0060] Specifically, there are four return springs and four limit columns 414. The four limit columns 414 are located at the four corners of the first bottom plate 411 in a one-to-one correspondence. The four return springs are mounted on the outside of the four limit columns 414 in a one-to-one correspondence, so that the elastic force applied to the moving seat 42 is more uniform, which is conducive to making the movement of the moving seat 42 more stable.

[0061] In other embodiments, only one relatively large return spring may be disposed on the first bottom plate 411 , and the return spring is disposed in the middle area of ​​the first bottom plate 411 , so as to stably support the moving seat 42 .

[0062] In this embodiment, a receiving cavity 415 is defined at the bottom of the fixing seat 41 , the first contact switch 44 is disposed in the receiving cavity 415 , and a contact of the first contact switch 44 extends upward to the first bottom plate 411 .

[0063] The first contact switch 44 is accommodated by providing an accommodating cavity 415, and only the contact of the first contact switch 44 extends out from the first bottom plate 411, so that when the movable seat 42 is pressed down, the movable seat 42 will only press against the contact of the first contact switch 44, and will not hit the first contact switch 44, thereby preventing the first contact switch 44 from being damaged. Moreover, the power cord of the first contact switch 44 is also in the accommodating cavity 415, which can hide the power cord.

[0064] In this embodiment, the detection device 4 also includes a fixing member 45, and at least one of the first side panels 412 is fixedly connected to the shelf 3 via the fixing member 45. The fixing member 45 is specifically a fixing bolt, and the fixing bolt fixes the first side panel 412 to the shelf 3, thereby securing the fixing seat 41 on the shelf 3.

[0065] In this embodiment, the movable seat 42 includes a second bottom plate 421 and a second side plate 422, and the second side plates 422 are provided on the four sides of the upper part of the second bottom plate 421, and a placement cavity 423 for placing the water storage component 100 is formed between the four second side plates 422 and the second bottom plate 421.

[0066] The movable seat 42 forms the placement cavity 423 through the second bottom plate 421 and the four second side plates 422, so that after the water storage component 100 is placed in the placement cavity 423, the four second side plates 422 are enclosed outside the water storage component 100 to make the position of the water storage component 100 more stable. At the same time, through the setting of the second side plate 422 and the close proximity of the second side plate 422 to the first side plate 412, it is also beneficial to strengthen the limiting effect between the movable seat 42 and the fixed seat 41, so that the movable seat 42 can stably move along the height direction.

[0067] Preferably, one side of the second bottom plate 421 extends outward to form an extension plate 424 , and the first side plate 412 is provided with a buckle 416 , which is used to abut against the upper part of the extension plate 424 to limit the movable seat 42 from detaching upward from the fixed seat 41 .

[0068] The buckle 416 of the fixed seat 41 abuts against the upper part of the extension plate 424 of the movable seat 42, thereby limiting the movable seat 42 from continuing to move upward after moving to a preset height. Therefore, when the user takes out the water storage component 100, the movable seat 42 can be quickly pushed upward under the thrust of the return spring. Therefore, the buckle 416 is provided to abut against the movable seat 42, which can limit the movable seat 42 from upwardly detaching from the fixed seat 41 and ensure smooth use.

[0069] Specifically, an inclined guide surface is provided on the top side of the buckle 416, so that when installing the movable seat 42, it is only necessary to press down the movable seat 42 to allow the movable seat 42 to move down along the guide surface, and finally allow the buckle 416 to be clamped on the upper part of the extension plate 424 to complete the installation of the movable seat 42. The installation method is simpler and faster.

[0070] Furthermore, the inner wall of the first side plate 412 of the fixing seat 41 facing the extension plate 424 is provided with a ridge 417 along the height direction, and the extension plate 424 is provided with a groove 425 in the area corresponding to the ridge 417 , and the ridge 417 fits into the groove 425 .

[0071] Through the matching arrangement of the convex strip 417 and the concave groove 425 , a guiding function can also be played between the movable seat 42 and the fixed seat 41 , so as to further enable the movable seat 42 to move more stably along the height direction.

[0072] In this embodiment, a plurality of ribs 426 are provided at intervals on the inner side of the second side plate 422 along its length direction, and the ribs 426 extend along the height direction, so as to strengthen the structural strength of the second side plate 422. Therefore, after the user takes in and out the water storage component 100 multiple times and causes the water storage component 100 to collide with the second side plate 422 multiple times, the second side plate 422 is not easily damaged and has a longer service life.

[0073] In the present embodiment, a first avoidance opening 418 for the water storage component 100 to enter and exit is provided in an upper area of ​​the first side plate 412 at the front side of the first bottom plate 411, and a second avoidance opening 427 for the water storage component 100 to enter and exit is provided in an upper area of ​​the second side plate 422 at the front side of the second bottom plate 421. Specifically, when the water storage component 100 is not placed on the movable seat 42, the lower edge of the first avoidance opening 418, the lower edge of the second avoidance opening 427 and the upper edge of the shelf 3 are flush, so that the user can conveniently place the water storage component 100 on the movable seat 42. After the water storage component 100 is placed on the movable seat 42, the movable seat 42 moves downward, so that the second side plate 422 and the shelf 3 on the front side of the fixed seat 41 can block the water storage component 100, and then the water storage component 100 can be stably placed on the movable seat 42 under non-human conditions, which is convenient for users to use and has higher practicality.

[0074] The refrigerator also includes a second contact switch 5, which is electrically connected to the controller. The second contact switch 5 is used to contact the water storage component 100 when the water storage component 100 is placed on the detection device 4. When the shelf 3 is arranged in the refrigerating chamber 11, the second contact switch 5 is arranged in the refrigerating chamber 11 and is located above the detection device 4. When the shelf 3 is arranged on the inner side of the door body 2, the second contact switch 5 is arranged on the inner side of the door body 2 and is located above the detection device 4.

[0075] By providing the second contact switch 5, when the water storage component 100 is placed on the detection device 4, the water storage component 100 can abut against the contact of the second contact switch 5, so that the second contact switch 5 can send a signal to the controller to indicate that the water storage component 100 is placed on the detection device 4 at this time, in conjunction with the detection function of the first contact switch 44, it can be judged more accurately whether the water in the water storage component 100 is sufficient.

[0076] In this embodiment, the fixed seat 41 and the movable seat 42 are both made of plastic material, so they are easier to process and manufacture, and the cost is also lower.

[0077] The utility model also relates to a refrigerator, comprising:

[0078] A box body 1, wherein a refrigerating chamber 11 is provided in the box body 1, and an opening 12 connected to the refrigerating chamber 11 is formed on one side of the box body 1;

[0079] A door body 2, the door body 2 is hinged to the box body 1 to open or close the opening 12;

[0080] A shelf 3, wherein the shelf 3 is disposed on the inner side of the refrigerating chamber 11 and / or the door body 2;

[0081] The detection device 4 includes a movable seat 42, an elastic reset member 43, a first contact switch 44 and a controller. The movable seat 42 is placed on the shelf 3 and can move relative to the shelf 3 in the height direction. The movable seat 42 is used for placing the water storage member 100. The elastic reset member 43 is arranged between the shelf 3 and the movable seat 42. The first contact switch 44 is arranged on the shelf 3 and below the movable seat 42. The first contact switch 44 is electrically connected to the controller.

[0082] When the water level of the water storage member 100 is greater than a preset water level, the movable seat 42 can be pressed downward to press the first contact switch 44; when the water level of the water storage member 100 is less than the preset water level, the elastic reset member 43 pushes the movable seat 42 upward to disengage from the first contact switch 44.

[0083] That is, the movable seat 42 is directly arranged on the shelf 3, and when the water storage part 100 is placed on the movable seat 42 and the water level of the water storage part 100 is greater than the preset water level, the weight of the water storage part 100 can overcome the elastic force of the elastic reset part 43, press the movable seat 42 downward, and finally contact with the contact of the first contact switch 44, so that the first contact switch 44 can send a signal to the controller to reflect that there is enough water in the water storage part 100. When the water level of the water storage part 100 is less than the preset water level, the elastic force of the elastic reset part 43 can offset the gravity of the water storage part 100, so that the movable seat 42 is separated from the first contact switch 44, thereby reflecting that the water storage part 100 is in a state of lack of water. Therefore, when the refrigerator of the present application detects the water level of the water storage part 100, there is no need to use a liquid level sensor for detection, thereby reducing equipment costs and making the detection method more reliable.

[0084] In summary, in the refrigerator of the present invention, there is no need to use a high-cost liquid level sensor to remind whether the water level of the water storage part is sufficient. Specifically, when the water level of the water storage part is greater than the preset water level, the weight of the water storage part can overcome the elastic force of the reset spring and press the movable seat to contact the contacts of the first contact switch, indicating that there is sufficient water in the water storage part. When the water level of the water storage part is lower than the preset water level, the reset spring can overcome the gravity of the water storage part and push the movable seat to move upward to separate the movable seat from the first contact switch, indicating that there is a lack of water in the water storage part. Therefore, the refrigerator of the present application does not need to use a liquid level sensor to detect the water level of the water storage part, can reduce equipment costs, and the method of using the first contact switch is more reliable.

[0085] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
