Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an improvement in the structure of a refrigeration equipment with an ice maker. Background Art

[0002] Many existing refrigeration equipment with ice makers are equipped with ice dispensing and ice crushing systems, so that users can realize the ice making function through the refrigeration equipment, thereby enhancing the functionality of the refrigeration equipment;

[0003] The commonly used ice making machine structures configured in refrigeration equipment mainly include:

[0004] An ice storage box is provided with an ice storage space therein, an ice crushing motor and an ice pushing piece connected to the ice crushing motor are arranged inside the ice storage box, and the ice pushing piece is a spiral rod, which is transmission-connected to the ice crushing motor. When the ice crushing motor rotates, it can drive the ice pushing piece to spirally rotate, thereby pushing the ice cubes in the ice storage box outwards. An ice outlet is provided on the side wall of the ice storage box, which can be used to realize ice outlet.

[0005] However, currently, few ice-crushing motors in this type of ice-making base have stall detection. For ice-crushing motors without stall detection, once ice cubes are stuck, this state cannot be determined and cannot be automatically restored. Customers need to manually clean the ice cubes, which results in a poor user experience.

[0006] If we want to add stall judgment on this basis, such as judging whether the motor is stalled by collecting the current of the motor, it will not only cause major changes to the existing products, but also lead to a significant increase in costs.

[0098] The utility model provides an embodiment of a refrigeration device having an ice maker 200, the refrigeration device comprising:

[0099] Box 100, door, and refrigeration system arranged inside box 100

[0100] Specifically, a storage space 110 is formed inside the box 100;

[0101] The storage space 110 may be divided into a refrigerating chamber and a freezing chamber disposed below the refrigerating chamber.

[0102] A door body, configured to be rotatably connected to the box body 100 to open or close the storage space 110;

[0103] The door body includes a refrigerating door body arranged at the refrigerating chamber, and the refrigerating door body includes a first refrigerating door body and a second refrigerating door body.

[0104] The first refrigerating door body and the second refrigerating door body can both rotate relative to the cabinet body 100 to open or close the refrigerating chamber by cooperating with each other.

[0105] a compressor configured to compress a refrigerant;

[0106] a condenser configured to condense the refrigerant;

[0107] an evaporator configured to evaporate the refrigerant condensed by the condenser, wherein the refrigerant evaporated by the evaporator is configured to cool the storage space 110;

[0108] The refrigerant circulation loop allows the condensate to circulate in a loop consisting of a compressor, an evaporator, a condenser, a solenoid valve and a throttling device;

[0109] The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, a solenoid valve, an evaporator and a throttling device.

[0110] A refrigerant circulation loop is formed between the compressor, the condenser, the solenoid valve, the evaporator and the throttling device, so that the refrigerant can circulate among the compressor, the condenser, the solenoid valve, the evaporator and the throttling device.

[0111] The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve refrigeration of the items in the box 100.

[0112] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0113] The evaporator may cool the items in the cabinet 100 by using latent heat of evaporation of the refrigerant.

[0114] The ice maker 200 is disposed in the storage space 110 and assembled on the box body 100;

[0115] Specifically, the ice maker 200 is arranged in the refrigerating chamber and is assembled and fixed on the inner wall of the refrigerating chamber to achieve the ice making function.

[0116] The ice making machine 200 has a structure including:

[0117] The ice storage box 210 has an ice storage space formed therein and an ice outlet formed on the top thereof;

[0118] Ice crushing motor 220;

[0119] The ice pusher 230 is drivingly connected to the ice crushing motor 220 and arranged in the ice storage space. The ice pusher 230 can be rotated under the drive of the ice crushing motor 220 to push the ice cubes in the ice storage space to the ice outlet.

[0120] In some embodiments of the present application, a mounting opening is provided on the top of the ice storage box 210, and the ice crushing motor 220 is transmission-connected to the ice pushing member 230 via a connecting member.

[0121] The ice pushing member 230 is an ice pushing screw rod, which is arranged in a spiral shape along the height direction of the ice storage box 210 .

[0122] It can be used to push the ice cubes in the ice storage box 210 toward the ice outlet.

[0123] In order to realize the connection between the ice-pushing screw and the ice-crushing motor 220, two raised columns are arranged at the end of the ice-pushing screw. The connecting piece is a connecting ear plate connected to the transmission shaft of the ice-crushing motor 220. The connecting ear plate and the two raised columns are cross-arranged at the installation port, so that when the ice-crushing motor 220 rotates, the ice-pushing screw can be driven to rotate accordingly.

[0124] The ice guide component 240 is located at the end thereof. The ice guide component 240 is an ice guide cylinder. Both ends of the ice guide cylinder are connected. The ice guide cylinder can be used to guide the ice cubes pushed to the position so that they can be sent out from the ice outlet.

[0125] An ice knife is provided at the ice outlet to crush the ice cubes.

[0126] In some embodiments of the present application, the ice maker 200 is also provided with an ice selection rod, which is connected to the ice selection rod through an ice selection motor to control whether the ice selection rod is pulled. In order to achieve the effect of producing whole ice, the ice selection rod is pulled up and the spiral rod is rotated to push the ice cubes towards the ice outlet.

[0127] The ice selection lever is connected to a shielding member. When the ice selection lever is pulled up, the shielding member opens the ice outlet. At this time, the area of ​​the ice outlet is larger than the ice cube. Under the push of the ice pushing screw, the entire ice cube can be pushed out to achieve the effect of discharging whole ice.

[0128] When the ice crushing mode is selected, the ice selection lever does not move, and it drives the shielding member to partially block the ice outlet. At this time, the opening of the ice outlet is small, and the ice cubes are continuously pushed toward the ice outlet through the ice guiding member 240 under the spiral force of the ice pushing screw. Since an ice knife is provided at the ice outlet, the ice cubes will be crushed due to the two forces of the ice knife and the ice pushing screw, thereby achieving crushed ice.

[0129] The connection structure of the ice selection pull rod, the ice selection motor and the shielding member can directly adopt the structure in the prior art, which will not be described in detail here.

[0130] When the ice maker 200 is in the whole ice mode, ice is usually not easily blocked. However, when ice cubes are stored in the ice storage box 210 for too long or ice cubes are melted and then condensed, ice cubes may stick together, which may block the ice outlet and cause the ice crushing motor 220 to stall.

[0131] When the ice maker 200 is in the ice crushing mode, the ice may be blocked by the forward thrust of the ice crushing motor 220 and the ice blades, thereby causing the motor to stall.

[0132] However, the current ice crushing motor 220 usually does not have stall feedback, and even if the ice crushing motor 220 is stalled, it cannot be detected.

[0133] In order to effectively detect the stall of the ice crushing motor 220, the structure of the ice maker 200 is improved. When setting, a detection protrusion 250 is correspondingly set on the outer surface of the ice guide component 240;

[0134] A sensing element 300 is arranged on the side wall of the ice storage box 210, which can be pressed and triggered to generate a trigger signal when the detection protrusion 250 rotates to a position corresponding to the detection protrusion 250;

[0135] Specifically, the sensing element 300 is mounted on the inner wall of the ice storage box 210 and is located in the inner space of the ice storage box 210 , and its position corresponds to the position of the ice guide component 240 .

[0136] When the ice crushing motor 220 rotates, the ice guide component 240 connected thereto will be driven to rotate, and the detection protrusion 250 on the outer wall of the ice guide component 240 will rotate circumferentially. When it rotates to the position of the sensing element 300, it will touch and press the sensing element 300, and the sensing element 300 will be touched to form a trigger signal.

[0137] The control element communicates with the sensing element 300, and is used to receive a trigger signal from the sensing element 300, and generate a detection result of the stalled state of the ice crushing motor 220 according to the trigger signal.

[0138] Every time the sensing element 300 is triggered by the detection protrusion 250 , it will send a trigger signal to the control element. The control element has a built-in timing module, which can be used to record the time interval between any two adjacent trigger signals.

[0139] When the user takes ice, the ice-pushing spiral rod rotates, and the ice-guiding component 240 rotates together. The detection protrusion 250 arranged on it rotates, and the sensing element 300 is fixed while the detection protrusion 250 rotates. By obtaining the state change of the trigger signal formed by the sensing element 300, it can be determined whether the ice-pushing component 230 and the ice-crushing motor 220 are rotating normally.

[0140] Taking one detection protrusion 250 as an example, through experimental calculation, when the ice storage box 210 is full of ice, the time required for the detection protrusion 250 to rotate one circle from the first triggering of the sensing element 300 to the next triggering of the sensing element 300 is T2, and T3 is pre-stored in the control element, and T3 is greater than T2.

[0141] When the ice storage box 210 is empty, the time required for the detection protrusion 250 to rotate one circle from the first triggering of the sensing element 300 to the next triggering of the sensing element 300 is T1, which is pre-stored in the control element.

[0142] During the rotation of the ice crushing motor 220, if a stall occurs, there are two positions. One is that the ice pushing member 230 rotates to a position away from the sensing element 300 and a stall occurs. At this time, the detection protrusion 250 cannot trigger the sensing element 300, that is, the sensing element 300 is not triggered.

[0143] Alternatively, the ice crushing motor 220 just rotates to the position where the detection protrusion 250 triggers the sensing element 300 and stops rotating. At this time, the sensing element 300 is in a state of being triggered all the time.

[0144] If the sensing element 300 has not been triggered since the last time it was triggered, that is, at this time, the time interval between the two times the sensing element 300 is triggered will exceed T3, and the sensing element 300 has not been triggered after exceeding T3, it means that the change of the detection protrusion 250 is abnormal, and it has not been able to rotate to the sensing element 300 to trigger the sensing element 300, which means that the ice crushing motor 220 is blocked;

[0145] Alternatively, it is detected that the sensing element 300 is always in the triggering state, and the control element can always receive the triggering signal, that is, the detection protrusion 250 is always in the state of triggering the compression sensing element 300, which also means that the ice crushing motor 220 is blocked.

[0146] When the motor is stuck, continuing to run in one direction cannot relieve the jam. It is similar to a paper shredder. When you put paper in to shred it, if there is too much paper, it may get stuck. Forcing the motor to continue to rotate forward will not solve the paper jam. You need to reverse and exit first, and then try to rotate forward, which can usually solve the paper jam problem.

[0147] The same is true for the ice crushing motor 220. When the motor is blocked in forward rotation, it is first reversed by a certain angle and then tried to rotate forward, which can effectively solve the problem of ice jam.

[0148] When the control element can always obtain the trigger signal formed by the sensing element 300, or obtains that the time between two adjacent triggering of the sensing element 300 is longer than the pre-stored T3, it can be determined that the ice crushing motor 220 is blocked. At this time, the blockage problem can be solved by controlling the ice crushing motor 220 to rotate in the reverse direction.

[0149] If two adjacent triggering times of the sensing element 300 are within the normal time period between T2 and T3, it is determined that the ice crushing motor 220 is not blocked, and the ice crushing motor 220 is controlled to rotate normally.

[0150] The refrigeration device with the ice maker 200 in this embodiment can judge the rotation state of the ice crushing motor 220 by the cooperation of the detection protrusion 250 arranged on the ice guide component 240 and the sensing element 300 arranged on the wall of the ice storage box 210, thereby judging whether the ice crushing motor 220 is rotating smoothly as required, and thus judging whether the ice crushing motor 220 is blocked, thereby realizing the detection of the blockage of the ice crushing motor 220;

[0151] When it is detected that the ice crushing motor 220 is blocked, the ice crushing motor 220 can be controlled in its rotation direction, that is, the ice crushing motor 220 is controlled to rotate in the reverse direction to solve the problem of the ice crushing motor 220 blocking and release the ice crushing motor 220 blocking.

[0152] In terms of structural improvement, only a detection protrusion 250 is provided on the ice guide component 240, and a sensing element 300 is provided on the wall of the ice storage box 210. The ice pusher 230 is rotated to drive the detection protrusion 250 to trigger the sensing element 300. The overall structure is simple, and only a slight adjustment is made to the structure of the ice pusher 230. The overall change to the product is not significant. The cost of the adopted and improved components is low. Under the premise of very little cost increase, the reliability of the product is improved and the user experience is improved.

[0153] In some embodiments of the present application, the detection protrusion 250 is a protrusion formed from the outer surface of the ice guide component 240 or a protrusion assembled and fixed on the ice guide component 240;

[0154] That is, the detection protrusion 250 may be a protrusion formed integrally with the ice guide component 240 during molding;

[0155] Alternatively, the protrusion may be fixed to the ice deflector 240 along the circumference of the ice deflector 240 at a later time.

[0156] The protruding member may be a protruding block or a protruding strip, and no specific limitation is made here.

[0157] The sensing element 300 is a contact detection switch mounted on the wall of the ice storage box 210 , and the sensing element 300 is located on the rotation path of the detection protrusion 250 .

[0158] The contact detection switch can directly adopt the contact switch in the prior art, and will not be described in detail here.

[0159] The sensing element 300 is arranged on the rotation path of the detection protrusion 250 , so that when the detection protrusion 250 rotates, the sensing element 300 can be triggered to send a trigger signal, thereby accurately judging the rotation state of the ice crushing motor 220 .

[0160] The contact detection switch has two different position states. One position is that it is in the pressed down position. At this time, it is triggered and sends a high level signal.

[0161] Another position is that it is in the raised position, at which time it is not triggered and it sends a low level signal.

[0162] In some embodiments of the present application, a plurality of detection protrusions 250 are provided and arranged along the circumference of the ice guide component 240 , and the intervals between adjacent detection protrusions 250 are the same or different.

[0163] For the convenience of description, the present embodiment is described by taking four detection protrusions 250 as an example. There are four detection protrusions 250, namely C1, C2, C3, and C4.

[0164] Assuming that the speed of the ice crushing motor 220 is n, the detection protrusions 250 at the end of the ice guide component 240 are C1, C2, C3, and C4. According to the speed n of the ice crushing motor 220, it is usually calculated experimentally that when the ice box is empty, the time required from one detection protrusion 250C1 to the next detection protrusion 250C2 is t1;

[0165] When the ice box is full of ice, the time required from one detection protrusion 250C1 to the next detection protrusion 250C2 is t2.

[0166] When the detection protrusion 250 rotates to contact or sense the sensing element 300, it is set to a high level, and when it leaves the sensing range, it is set to a low level.

[0167] The user presses the ice taking lever to start taking ice. In the initial state, the state of the sensing element 300 is a low level. When the state changes to a high level, the timing starts;

[0168] Continue to take ice, and keep timing when the level becomes low, until the level of the sensing element 300 changes from low to high again, and then obtain the time interval tk, and make a judgment on tk.

[0169] Since the rotation speed of the ice crushing motor 220A is known, when there is more ice in the ice storage box 210, the load on the ice crushing motor 220 is greater and the rotation speed is slower at this time. When there is less ice or no ice in the ice storage box 210, the motor load is small and the rotation speed is fast. Due to the change in its rotation speed, the time interval between two adjacent triggerings of the detection protrusion 250 on the ice guide component 240 and the sensor element 300 will also change. Therefore, the length of the time interval between two adjacent triggerings of the sensor element 300 can also be used to judge the amount of ice in the ice storage box 210, and the user can be prompted when there are fewer ice cubes.

[0170] If 1.2 t2>tk>0.8 t2, it means that the ice crushing motor 220 is not blocked and the ice box is relatively full;

[0171] When 0.6 t2>tk>0.4 t2, it means that the ice crushing motor 220 is not blocked and the ice quantity in the ice box is medium;

[0172] When 1.3t1≥tk>1.2t1, it indicates that the ice crushing motor 220 is not blocked and the ice box is nearly empty.

[0173] The amount of ice cubes in the ice storage box 210 can also be determined by the time between two adjacent high-level trigger signals of the sensing element 300 .

[0174] In some embodiments of the present application, the detection protrusion 250 includes:

[0175] A protrusion body section 251, wherein the surface of the protrusion body section 251 opposite to the detection protrusion 250 is a smooth arc surface;

[0176] A first guide section 252 is arranged on one side of the protruding body section 251, and the first guide section 252 has a first guide surface 253 smoothly transitionally connected to the arc surface;

[0177] A second guide segment 254 is arranged on the other side of the protruding body segment 251, and the second guide segment 254 has a second guide surface 255 which is smoothly transitionally connected to the arc surface.

[0178] The protruding body section 251 with a smooth arc surface can ensure that the detection protrusion 250 can be smoothly pressed onto the sensing element 300 and trigger the sensing element 300 during the rotation process;

[0179] The first guide surface 253 can play a guiding role when the detection protrusion 250 rotates toward the sensing element 300;

[0180] The second guide surface 255 can guide the detection protrusion 250 when it is separated from the sensing element 300 .

[0181] In some embodiments of the present application, the distance between the first guide surface 253 of the first guide segment 252 and the outer side surface of the ice guide component 240 gradually increases along the rotation direction of the ice guide component 240;

[0182] The distance between the first guide surface 253 and the outer surface of the ice guide member 240 is initially small, which can facilitate the detection of the protrusion 250 rotating to the position of the sensing element 300. The distance increases along the rotation direction, so that the sensing element 300 starts to be compressed and triggered when it is close to the protrusion body section 251.

[0183] The distance between the second guide surface 255 and the outer side surface of the ice guide component 240 gradually decreases along the rotation direction of the ice guide component 240 .

[0184] The second guide surfaces 255 are arranged with a gradually decreasing distance therebetween, so that when the detection protrusion 250 is separated from the sensing element 300 , the distance therebetween gradually decreases, so that the two can be separated quickly.

[0185] In some embodiments of the present application, the first guide surface 253 is a first guide inclined surface or a first guide arc surface;

[0186] The second guide surface 255 is a second guide inclined surface or a second guide arc surface.

[0187] The use of a guiding inclined surface or a guiding arc surface can ensure that the detection protrusion 250 can smoothly press the trigger sensing element 300, thereby achieving the guiding effect of the first guiding surface 253 and the second guiding surface 255.

[0188] In some embodiments of the present application, a mounting portion 211 is formed on the inner wall of the ice storage box 210, and the mounting portion 211 has an opening 212, and the opening 212 faces the inner space of the ice storage box 210;

[0189] The sensing element 300 is mounted in the mounting portion 211 and at least partially extends out of the opening 212 .

[0190] In order to achieve the installation and fixation of the sensing element 300, a mounting portion 211 is provided on the inner wall of the ice storage box 210. The mounting portion 211 is a mounting groove formed on the inner wall of the ice storage box 210. An insertion hole is provided on the bottom wall of the mounting groove. The sensing element 300 is inserted into the insertion hole of the mounting groove. The sensing element 300 is a contact detection switch that can be reset after being pressed.

[0191] The contact detection switch includes a switch body and an arc-shaped switch pressing cap. The switch pressing cap has an arc-shaped pressing surface, and the top portion of the switch pressing cap extends out from the opening 212 .

[0192] The switch pressing cap is configured as an arc-shaped pressing surface to ensure that the detection protrusion 250 is in smooth contact with the sensing element 300 when rotating through it, and the detection protrusion 250 will not be stuck during the rotation process, thereby ensuring that it can smoothly rotate through the sensing element 300.

[0193] When the detection protrusion 250 rotates and passes by, the contact detection switch can be pressed and triggered.

[0194] When the detection protrusion 250 is away from the contact detection switch, the contact detection switch is reset to the initial position.

[0195] In some embodiments of the present application, a guide limiting portion 213 is formed at the opening portion 212 and extends toward the inner side of the mounting portion 211 , and can at least partially limit the detection matching portion to prevent it from escaping from the mounting portion 211 , and a guide curved surface 214 is formed on the outer side of the guide limiting portion 213 .

[0196] The guide limiting portion 213 is a guide limiting claw, which is arranged at the opening portion 212 to limit the sensing element 300 and prevent the sensing element 300 from escaping and falling from the mounting portion 211 .

[0197] The guide curved surface 214 formed on its outer side surface is used to ensure that when the detection protrusion 250 passes by, it contacts the detection protrusion 250 smoothly and does not hinder the rotation of the detection protrusion 250.

[0198] In some embodiments of the present application, the guide curved surface 214 is an arc-shaped guide surface, which extends from the outer edge of the opening portion 212 to the inner space of the mounting portion 211 to guide the detection protrusion 250 to the position of the sensing element 300 .

[0199] In some embodiments of the present application, a refrigeration device having an ice maker 200 is provided, comprising:

[0200] A box body 100, wherein a storage space 110 is formed inside the box body 100;

[0201] A door body, configured to be rotatably connected to the box body 100 to open or close the storage space 110;

[0202] a compressor configured to compress a refrigerant;

[0203] a condenser configured to condense the refrigerant;

[0204] an evaporator configured to evaporate the refrigerant condensed by the condenser, wherein the refrigerant evaporated by the evaporator is configured to cool the storage space 110;

[0205] The refrigerant circulation loop allows the condensate to circulate in a loop consisting of a compressor, an evaporator, a condenser, a solenoid valve and a throttling device;

[0206] The ice maker 200 is disposed in the storage space 110 and assembled on the box 100, and includes:

[0207] The ice storage box 210 has an ice storage space formed therein and an ice outlet formed on one side thereof;

[0208] Ice crushing motor 220;

[0209] The ice pusher 230 is connected to the ice crushing motor 220 and arranged in the ice storage space. The ice pusher 230 can be driven by the ice crushing motor 220 to rotate to push the ice in the ice storage space to the ice outlet. The ice pusher 230 includes:

[0210] The ice guide member 240 is located at the end thereof, and a detection portion is provided on the outer side surface of the ice guide member 240;

[0211] The detection matching part is arranged on the side wall of the ice storage box 210, and can sense the detection part and generate a trigger signal when the detection part rotates to a position corresponding to the detection part;

[0212] or being sensed by the detection unit so that the detection unit generates a trigger signal;

[0213] A control element, communicating with the detection cooperation part, for receiving a trigger signal of the detection cooperation part, and generating a detection result of the stalled state of the ice crushing motor 220 according to the trigger signal;

[0214] Alternatively, it is used to receive a trigger signal from the detection unit and generate a detection result of the stalled state of the ice crushing motor 220 according to the trigger signal from the detection unit.

[0215] That is, in this embodiment, detection can also be achieved by providing a detection part on the ice guide component 240 and a detection matching part on the wall of the ice storage box 210, and the detection part and the detection matching part are mutually coordinated detection sensing components, and the two are triggered by mutual induction rather than contact triggering.

[0216] The detection unit and the detection matching unit generate a trigger signal for the control element, and the control element determines whether the ice crushing motor 220 is blocked according to the state of the received trigger signal.

[0217] If the trigger signal is in a state of being continuously sent, or is not sent again for a maximum preset time pre-stored in the control element, it means that the ice crushing motor 220 is blocked.

[0218] In addition, the use of a contactless induction detection method allows the detection part and the detection matching part to accurately detect the rotation of the ice crushing motor 220 without contact. Compared with contact detection, there will be no problem of poor detection accuracy due to contact wear after long-term use, and the reliability is better.

[0219] During assembly, the detection matching portion can be directly fixed on the buckle of the wall of the ice storage box 210 through the buckle structure to achieve buckle fixation.

[0220] The detection part may be a triggering member for triggering the detection matching part, and the detection matching part is used to form a trigger signal, that is, when the detection matching part detects the detection part, it is triggered and forms a trigger signal and sends the trigger signal to the control element;

[0221] Alternatively, the detection matching portion may be set as a trigger element, and when the sensing element 300 rotates to the detection matching portion, it is triggered and generates a trigger signal that is sent to the control element.

[0222] When arranged, the sensing element 300 may be arranged on the ice guide member 240 or on the wall of the ice storage box 210;

[0223] Correspondingly, the detection matching portion is arranged on the wall of the ice storage box 210 or on the ice guiding component 240 .

[0224] In some embodiments of the present application, the detection part and the detection matching part are photoelectric detection switches, the detection part corresponds to a photoelectric detection receiving switch, and the detection matching part is a photoelectric detection sending switch.

[0225] In some embodiments of the present application, the detection portion is a magnetic sensing component, and the detection matching portion is a Hall induction sensor.

[0226] The magnetic sensing component is assembled on the ice guide component 240, and the Hall sensing sensor is assembled on the wall of the ice storage box 210. When the ice crushing motor 220 rotates, the ice guide component 240 and the magnetic sensing component can be driven to rotate. After rotating to the right position, they correspond to the Hall sensing sensor on the wall of the ice storage box 210. After the Hall sensing sensor is triggered, a trigger signal is sent.

[0227] Since the ice guide component 240 is constantly rotating, a magnetic induction component is provided on the ice guide component 240, and a Hall induction sensor is provided on the wall of the ice storage box 210. Since the Hall induction sensor needs to be wired, arranging it on the wall of the ice storage box 210 can avoid the problem of wiring entanglement caused by the rotation of the ice guide component 240, and installing the Hall induction sensor on the wall of the ice storage box 210 is more convenient for wiring installation.

[0228] In some embodiments of the present application, the detection part is a laser receiving sensor, and the detection matching part is a laser emitting sensor, and the two are used in combination.

[0229] In some embodiments of the present application,

[0230] A detection protrusion 250 is provided on the outer side of the ice guide member 240 at the end of the ice pusher 230;

[0231] The elastic pressing member 400 is mounted on the wall of the ice storage box 210 and is located on the rotation path of the detection protrusion 250;

[0232] In some embodiments of the present application, an installation groove 215 is provided on the inner wall of the ice storage box 210 and penetrates the wall of the ice storage box 210. Both ends of the installation groove 215 are open, one end is connected to the internal space of the ice storage box 210, and the other end is connected to the external space of the ice storage box 210. The installation groove 215 can be formed by providing an installation enclosure on the wall of the ice storage box 210.

[0233] The elastic pressing member 400 is assembled in the installation slot 215 , and two ends thereof extend out from openings at two ends of the installation slot 215 .

[0234] The elastic pressing member 400 is located on the rotation path of the detection protrusion 250 . When the ice guide component 240 rotates, the detection protrusion 250 can be driven to rotate, thereby pressing the elastic pressing member 400 located on the rotation path.

[0235] In some embodiments of the present application, the elastic pressing member 400 includes a pressing member body 410 and an elastic member 420 sleeved on the pressing member body 410 .

[0236] A first clamping portion 411 is disposed on the pressing member body 410 , a second clamping portion 216 is formed on the inner wall of the installation slot 215 , and one end of the elastic member 420 abuts against the first clamping portion 411 , and the other end abuts against the second clamping portion 216 .

[0237] When the elastic pressing member 400 is pressed by the detection protrusion 250 , the elastic member 420 is pressed. After the force on the elastic pressing member 400 is eliminated, the elastic member 420 can return to the position of the pressing member body 410 .

[0238] The trigger switch 500 is assembled and fixed on the inner wall of the box body 100, corresponding to the position of the elastic pressing member 400, and can be pressed by the elastic pressing member 400 to form a trigger signal;

[0239] The trigger switch 500 may directly adopt a contact detection switch, which may be triggered to form a trigger signal after being pressed.

[0240] The control element is connected to the trigger switch 500 for communication, receives the trigger signal of the trigger switch 500, and generates a detection result of the stalled state of the ice crushing motor 220 according to the trigger signal.

[0241] When the ice crushing motor 220 rotates, the detection protrusion 250 rotates to the elastic pressing member 400 and presses the elastic pressing member 400. The elastic pressing member 400 moves in the installation groove 215 and contacts the pressing trigger switch 500. The trigger switch 500 is triggered and sends a trigger signal to the control element.

[0242] When the detection protrusion 250 leaves the elastic pressing member 400 , the elastic pressing member 400 rebounds to its original position and leaves the trigger switch 500 , and the trigger switch 500 is disconnected.

[0243] As the detection protrusion 250 rotates, the trigger switch 500 is sometimes turned on and sometimes turned off, thereby determining the stalled state of the ice crushing motor 220 .

[0244] When a plurality of detection protrusions 250 are provided, the angle between adjacent detection protrusions 250 and the rotation speed of the ice-crushing motor 220 are known, thereby the interval time of the intermittent triggering of the trigger switch 500 can be known, and the interval time can be pre-stored in the control element. If the control element can always receive the trigger signal of the trigger switch 500 which is sometimes connected and sometimes disconnected, it means that the ice-crushing motor 220 is operating normally, otherwise it means that it is stalled.

[0245] By providing a detection protrusion 250 on the ice guide component 240, providing an elastic pressing member 400 on the ice storage box 210, and installing a trigger switch 500 on the inner wall of the box body 100, the ice storage box 210 can be made into a purely mechanical structure without electrical signal components and without the need for wire connection. The overall structure of the ice storage box 210 is simpler and easier to implement.

[0246] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0247] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
