Description

Food probe for refrigerator, food detection device and refrigerator

Technical Field

The invention belongs to the technical field of refrigerators, and particularly provides a food probe for a refrigerator, a food detection device and the refrigerator.

Background

Refrigerators are widely used as devices for freezing and refrigerating foods. When the refrigerator works, the ambient temperature of the environment in the storage compartment (such as a refrigerating compartment, a freezing compartment or a temperature changing compartment) is generally detected, and then the storage compartment is refrigerated according to the ambient temperature. Specifically, when the ambient temperature is higher than a preset temperature interval, the refrigerator is made to refrigerate the current storage compartment; when the ambient temperature is in a preset temperature interval, the refrigerator stops refrigerating the current storage compartment. For example, when the freezing compartment of a general refrigerator requires-20 ℃, the refrigerator stops refrigerating the freezing compartment when the ambient temperature of the freezing compartment is reduced to-20 ℃.

However, for most food materials, a certain time is needed for the cold energy to be transferred from the surface to the inside, so that the temperature of the inside of the food materials is different from the temperature of the environment of the storage compartment, the temperature of the inside of the food materials cannot be judged by the existing refrigerator, and the temperature of the inside of the food materials in the refrigerator is possibly too high or too low, and the fresh-keeping effect of the food materials is affected. For example, for steak to be fried, the center temperature of steak is optimal for the taste fried at 0 ℃. Therefore, the too high and too low temperature of the beefsteak during preservation can affect the taste of the beefsteak eaten by users.

As shown in FIG. 1, in some embodiments of the present invention, a food probe 100 includes a housing 110, a temperature measurement assembly 120, and a handle 130.

Wherein the housing 110 is integrally provided in a needle shape. The temperature measuring assembly 120 is disposed in the housing 110, and the temperature measuring assembly 120 is used to detect the temperature inside the food and transmit the detected temperature to the refrigerator 300 (shown in fig. 7). A handle 130 is provided at one end of the housing 110 for a user to grasp.

When the food probe 100 is used, a user holds the handle 130, inserts an end of the housing 110 remote from the handle 130 into food, so that the temperature measuring assembly 120 detects the temperature inside the food, and transmits the detected temperature to the refrigerator 300.

In the present invention, the food may be solid food (e.g., beef, pork, jelly, etc.) or liquid food (e.g., beverage, water, porridge, etc.).

As shown in fig. 1, the housing 110 is threadedly coupled to the handle 130. In addition, the person skilled in the art may also use any other possible connection method to fixedly connect the housing 110 and the handle 130 together, such as plugging, bonding, clamping, etc.

With continued reference to fig. 1, the temperature measuring assembly 120 is fixedly connected with the housing 110 and the handle 130, respectively, to prevent the temperature measuring assembly 120 from shaking in the housing 110.

The temperature sensing assembly 120 in some embodiments of the present invention is described in detail below with reference to fig. 1-4.

As shown in fig. 1-3, in some embodiments of the present invention, a temperature sensing assembly 120 includes a base 121, at least one food temperature sensing member 122, a communication module 123, and a power module 124. Wherein the base 121 extends along the length direction of the housing 110. At least one food temperature measuring member 122 is fixed to the base 121 and serves to detect the temperature inside the food. The communication module 123 is fixed to the base 121 and serves to transmit the temperature detected by the food temperature measuring member 122 to the refrigerator 300. The power supply module 124 is fixed to the base 121 and supplies power to the food temperature measuring member 122 and the communication module 123.

The substrate 121 may be a rod-shaped structure or a plate-shaped structure, and the material of the substrate may be plastic, wood or metal.

The food temperature measuring member 122 is a temperature measuring resistor, which may be a sheet structure, a plate structure, or any other feasible structure.

Alternatively, the food temperature measuring member 122 abuts the housing 110 such that the food temperature measuring member 122 detects the temperature of the food by detecting the temperature of the housing 110.

In other embodiments of the present invention, a person skilled in the art may also provide a notch corresponding to the food temperature measuring member 122 on the housing 110 as required, so that the food temperature measuring member 122 is exposed to the outer surface of the housing 110 through the notch, thereby enabling the food temperature measuring member 122 to directly detect the temperature of the food. And optionally the food temperature measuring member 122 is provided as an infrared temperature measuring member.

In some embodiments of the present invention, the temperature measuring assembly 120 preferably includes two food temperature measuring members 122 spaced apart to detect temperatures at two different locations inside the food by the two food temperature measuring members 122, thereby allowing the refrigerator 300 to calculate an average temperature inside the food through the two temperatures.

Furthermore, in other embodiments of the present invention, one skilled in the art may also arrange the food temperature measuring member 122 in any other feasible number, such as one, three, five, etc., as desired.

In some embodiments of the invention, the communication module 123 is a bluetooth module or a WiFi module. Or the person skilled in the art may arrange the communication module 123 as any other feasible communication module, such as a ZigBee communication module, as desired.

As shown in fig. 1, the power supply module 124 is disposed at an end of the housing 110 remote from the handle 130. The power supply module 124 abuts against the housing 110, so that the power supply module 124 plays a role of fixing the temperature measuring assembly 120. Alternatively, the power supply module 124 abuts the peripheral wall and the tapered side wall of the housing 110.

In other embodiments of the present invention, those skilled in the art will appreciate that the power module 124 may be positioned at any other feasible location, such as, for example, the power module 124 may be positioned in the middle of the base 121 or near one end of the handle 130.

As shown in fig. 4, the power supply module 124 includes a heat insulating member 1241 and a battery 1242 provided in the heat insulating member 1241. The heat insulating member 1241 serves to insulate the battery 1242 to block heat/cold outside the power supply module 124 from being transferred to the battery 1242. Further, a vacuum chamber 124101 is defined within the insulating member 1241 such that the insulating member 1241 blocks heat/cold energy from outside the power module 124 from being transferred to the battery 1242 through the vacuum chamber 124101.

With continued reference to fig. 4, the insulating member 1241 includes an outer layer portion 12411 and an inner layer portion 12412, with a vacuum cavity 124101 formed between the outer layer portion 12411 and the inner layer portion 12412. Wires connected to the battery 1242 pass through the outer layer part 12411 and the inner layer part 12412 to electrically connect the battery 1242 with the food temperature measuring member 122 and the communication module 123, respectively.

Wherein the outer layer 12411 and the inner layer 12412 may be made of any feasible material, such as stainless steel. Vacuum cavity 124101 is evacuated.

As shown in fig. 1 to 3, the temperature measuring assembly 120 further includes an environmental temperature measuring member 125, and the environmental temperature measuring member 125 is used for detecting the temperature of the environment where the food is located. The environmental temperature sensing member 125 is a temperature sensing resistor, which may be a sheet-like structure, a plate-like structure, or any other feasible structure.

With continued reference to fig. 1-3, the ambient temperature measuring member 125 is fixedly connected to the base 121 and extends from the base 121 into the handle 130. And the ambient temperature measurement member 125 is electrically connected with the battery 1242.

It will be appreciated by those skilled in the art that by configuring the environmental temperature measurement member 125 for the physical probe, the food probe 100 is enabled to simultaneously acquire the temperature inside the food and the temperature at which the food is located, thereby determining the food cooling rate or heating rate according to the temperature difference between the two. The refrigerator 300 of the present invention can control the cooling rate of the storage compartment 311 (as shown in fig. 7) according to the cooling rate, so that the food can be cooled uniformly, and the outside of the food is prevented from being frozen while the temperature of the inside is still higher when the cooling rate of the storage compartment 311 is too fast.

As shown in fig. 1 to 3, the temperature measuring assembly 120 further includes a radial limiter 126 fixedly connected to the base 121, and the radial limiter 126 is configured to radially fix the base 121 and the housing 110.

As can be seen in fig. 1 to 3, the radial stopper 126 is located at the middle of the base 121, and the radial stopper 126 includes a plurality of C-shaped claws 1261 having elasticity. The C-shaped claw 1261 is deformable by force in the radial direction of the housing 110.

In some embodiments of the present invention, the resilient C-shaped fingers 1261 can always abut against the housing 110, thereby enabling the temperature sensing assembly 120 to be closely abutted together radially by the housing 110 while also facilitating assembly of the temperature sensing assembly 120 into the housing 110 by an assembler.

Furthermore, in other embodiments of the present invention, one skilled in the art may arrange the radial stop 126 in any other viable configuration, such as a coil spring, a V-shaped spring, etc., as desired.

The handle 130 in some embodiments of the present invention is described in detail below with reference to fig. 1-3.

As shown in fig. 1-3, in some embodiments of the present invention, the handle 130 is provided with a hollow hanger bar 131 extending toward the temperature sensing assembly 120, the hanger bar 131 being fixedly connected to the base 121 and located within the housing 110.

Specifically, the end of the hanger bar 131 near the base 121 is provided with a fixing hole (not labeled in the drawing) so that the base 121 is inserted into the fixing hole and thus fixed together with the hanger bar 131 at least in the radial direction while the environmental temperature measuring member 125 is extended into the hanger bar 131.

As shown in fig. 1, in the assembled state of the food probe 100, the temperature measuring assembly 120 can be triple-fixed by fixing the base 121 and the housing 110 to the handle 130, abutting the C-shaped claw 1261 to the housing 110, and abutting the power supply module 124 to the housing 110, thereby fixing the temperature measuring assembly 120 to the housing 110 and preventing the temperature measuring assembly 120 from shaking.

As shown in fig. 1 to 3, the portion of the handle 130 exposed outside the housing 110 is tapered as a whole to facilitate the grip of the user, and at the same time, the handle 130 is prevented from being inserted into the food material along with the housing 110, and is not easy to be pulled out.

Furthermore, in other embodiments of the present invention, the person skilled in the art may arrange the handle 130 in any other feasible structure, such as a rod-like structure, a gourd-like structure, etc., as desired.

Alternatively, the end of the ambient temperature measuring member 125 remote from the base 121 may be located within the hanger bar 131 or may be located in a portion of the handle 130 exposed outside of the housing 110.

As shown in fig. 1 to 3, a power receiving terminal 132 is disposed on the handle 130, and the power receiving terminal 132 is electrically connected to the power supply module 124 to charge the power supply module 124.

Optionally, a power receiving terminal 132 is disposed at an end of the handle 130 away from the housing 110, and a wire connected to the power receiving terminal 132 extends into the housing 110 through the hanger bar 131 to be electrically connected to a battery 1242 of the power supply module 124.

As shown in fig. 1-3, the food probe 100 further includes an identity tag 140 that can be recognized by the refrigerator 300. The identity tag 140 is disposed on the handle 130.

In addition, the identity tag 140 may be provided on the housing 110 as desired by those skilled in the art. Except that the housing 110 is small in size and not easily arranged.

As shown in fig. 5, the identity tag 140 includes an RFID electronic tag 141 fixed on the handle 130, and an aerogel insulation layer 142 is coated on the outside of the RFID electronic tag 141.

Wherein, RFID is Radio Frequency Identification abbreviation, is a contactless automatic identification technology. The aerogel insulation layer 142 is used for insulating the RFID electronic tag 141, and preventing the RFID electronic tag 141 from being damaged at high and low temperatures.

In addition, since the aerogel has a certain plasticity, the identity tag 140 can be attached on the outer surface of the handle 130.

If the handle 130 is a structure having a housing, the identification tag 140 may also be attached to the inner surface of the housing of the handle 130.

In addition, although not shown in the drawings, in order to secure the communication capability of the food probe 100, an antenna may be further configured for the food probe 100 and connected to the communication module 123.

The antenna may be wound around the outside of the hanger bar 131 or may extend into the handle 130 to prevent food from shielding its signals.

In the present invention, the food probe 100 may be configured on the refrigerator 300 as a part of the refrigerator 300; can also be used as a matching part of the refrigerator 300 and be arranged on the refrigerator 300 when needed.

In still other embodiments of the present invention, as shown in fig. 6, the present invention also provides a food detection device 200 comprising a housing 210 and the food probe 100 described in any of the previous embodiments.

As shown in fig. 6, the base 210 is provided with a plurality of receiving locations 211, and each receiving location 211 is used for receiving one food probe 100.

Further, a charging terminal (not shown) matched with the power receiving terminal 132 is further disposed on the base 210, so that the base 210 abuts against the power receiving terminal 132 through the charging terminal and charges the food probe 100.

Further, the base 210 may be further configured with a battery, so that the base 210 can charge the food probe 100 at any time and any place.

Still further, the base 210 may be further configured with a wireless communication module, so that the base 210 is connected with a terminal device such as a refrigerator 300 and a mobile phone through the wireless communication module, thereby enabling a user to obtain the number of food probes 100 placed on the base 210 and obtain the electric quantity of each food probe 100.

As shown in fig. 7, in other embodiments of the present invention, the present invention also provides a refrigerator 300 including a cabinet 310, a door 320, a controller 330, and a wireless communication module. Wherein, a plurality of storage compartments 311 are defined in the case 310. The door 320 is installed on the case 310 to shield the storage compartment 311. The controller 330 is communicatively coupled to a wireless communication module that is configured to receive information from the food probe 100 and transmit the information to the controller 330.

The storage compartments 311 may be one, three, four, five, or any other possible number, in addition to the two shown in fig. 7.

Further, the refrigerator 300 is provided with an RFID reader 340 for each storage compartment 311 thereon, and the RFID reader 340 is electrically connected to the controller 330. The RFID reader 340 is used to read the RFID electronic tag 141 on the food probe 100.

In the present invention, the refrigerator 300 may be a direct-cooling refrigerator 300 or an air-cooled refrigerator 300.

The method of using the food probe 100 and the method of controlling the refrigerator 300 based thereon in the present invention will be described in detail with reference to the following.

First, the user takes the food probe 100 out of the food detection device 200 and inserts the food probe 100 into food.

Then, the user brings the RFID electronic tag 141 on the food probe 100 close to the RFID reader 340 corresponding to the current storage compartment 311 to be read by the refrigerator 300 before placing the food inserted with the food probe 100 into the storage compartment 311.

Subsequently, the controller 330 of the refrigerator 300 determines which storage compartment 311 is filled with food materials by the RFID reader 340 reading the data, and is communicatively connected to the communication module 123 of the food probe 100 by its wireless communication module. So that the controller 330 acquires the internal temperature of the food detected by the food probe 100 in real time and controls the cooling of the storage compartment 311 according to the temperature. The control includes raising the cooling power, lowering the cooling power, and stopping the cooling. For example, when the difference between the temperature measured by the environmental temperature measuring means 125 and the temperature measured by the food temperature measuring means 122 is too large, the cooling power is reduced, and when the difference between the temperature measured by the environmental temperature measuring means 125 and the temperature measured by the food temperature measuring means 122 is too small, the cooling power is increased.

The communication connection between the refrigerator 300 and the food probe 100 may enable the refrigerator 300 to obtain connection information of the food probe 100 from the RFID electronic tag 141 when the RFID reader 340 reads the RFID electronic tag 141, thereby actively establishing a communication connection with the food probe 100.

Based on the foregoing description, it can be understood by those skilled in the art that by configuring the refrigerator 300 with the food probe 100, the refrigerator 300 can detect the temperature inside the food through the food probe 100 and correspondingly control the refrigeration of the corresponding storage compartment 311, thereby improving the fresh-keeping effect of the refrigerator 300 on the food and improving the taste of the food.

Thus far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present invention is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present invention, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present invention will fall within the protection scope of the present invention.
