Detailed Description
The embodiment firstly provides a wine cabinet, can realize the high accuracy control to the inside temperature of wine cabinet, guarantees that refrigerating system opens in time, satisfies the storage demand of article. Fig. 1 is a schematic structural view of a wine cabinet 100 according to an embodiment of the present invention. As shown in fig. 1, a first temperature sensor 310 and a second temperature sensor 320 are respectively provided at different positions inside the wine cabinet 100.
In one particular embodiment, the wine cabinet 100 may generally include: a case 110 and a door 120. Wherein, the storage space 111 is defined inside the case 110. The number and configuration of the storage spaces 111 may be configured as desired. Each storage space 111 may be divided into a plurality of storage areas by a partition plate, and stores articles using racks or drawers. As a household electrical appliance for refrigerating wine, the wine cabinet 100 may be configured as a refrigerating space in which various kinds of wine can be stored. The storage space 111 is in fact a greenhouse of the wine cabinet 100, and the wine cabinet 100 shown in fig. 1 is provided with one storage space 111, i.e. with one greenhouse.
The door 120 is disposed on the front surface of the case 110 to close the storage space 111. The door 120 may be disposed corresponding to the storage spaces 111, that is, each storage space 111 corresponds to one or more doors 120. The number of the storage spaces 111 and the door 120, and the functions of the storage spaces 111 may be actually selected according to the specific situation. The door 120 may be pivotally disposed on the front surface of the case 110, and may be opened in a drawer manner, so as to realize a drawer-type storage space 111, where the drawer-type storage space 111 is often provided with a metal sliding rail, so that the effect of opening and closing the drawer is soft and noise is reduced.
The first temperature sensor 310 and the second temperature sensor 320 are respectively provided at different positions inside the wine cabinet 100, and in a specific embodiment, as shown in fig. 1, the first temperature sensor 310 and the second temperature sensor 320 are provided at different positions of the single storage space 111. In a preferred embodiment, the first temperature sensor 310 and the second temperature sensor 320 are both thermal resistance sensors. The principle of thermal resistance sensor temperature measurement is: the resistance of the thermal resistor changes along with the temperature change, and the temperature can be obtained by measuring the resistance of the resistor. And, the resistance and the temperature may be inversely related, i.e., the larger the resistance, the lower the temperature; the smaller the resistance, the higher the temperature.
Therefore, in this embodiment, the first temperature sensor 310 and the second temperature sensor 320 may obtain the resistance value of the resistor through the AD sampling circuit, so as to obtain the first temperature value and the second temperature value. Specifically, a first resistance value is obtained by using a circuit of the first temperature sensor 310, and the first temperature value is determined according to the first resistance value; the second resistance value is obtained by the circuit of the second temperature sensor 320, and the second temperature value is determined according to the second resistance value.
When the obtained resistance value is abnormal, for example, the resistance value is close to zero or close to infinity, it can be determined that the first temperature sensor 310 or the second temperature sensor 320 has failed. Specifically, if the resistance value is close to zero, the temperature sensor is indicated to be short-circuited; if the resistance value is close to infinity, the temperature sensor is indicated to be disconnected. If the first resistance value is close to zero, it may be determined that the first temperature sensor 310 has a short circuit fault; if the first resistance value is close to infinity, it may be determined that the first temperature sensor 310 is out of circuit. Likewise, if the second resistance value is close to zero, it may be determined that the second temperature sensor 320 has a short circuit fault; if the second resistance value is close to infinity, it can be determined that the second temperature sensor 320 has an open circuit fault. In the case where the first temperature sensor 310 fails and the second temperature sensor 320 operates normally, the refrigeration system may be controlled according to the second temperature value. In the case where the first temperature sensor 310 is operating normally and the second temperature sensor 320 is malfunctioning, the refrigeration system may be controlled according to the first temperature value.
As mentioned above, various wines may be stored within the wine cabinet 100, and in particular, the wine cabinet 100 is used to chill wine products, and the wine cabinet 100 further includes a refrigeration system to provide refrigeration to the storage space 111. The refrigeration system provides different amounts of cold to the storage space 111, so that the temperature of the storage space 111 is different to meet the storage temperature suitable for different wines. In a preferred embodiment, the refrigeration system comprises an evaporator and a compressor, and the evaporator is disposed at the upper middle portion of the rear side of the interior of the wine cabinet 100, the first temperature sensor 310 is disposed at the middle position of one side wall of the interior of the wine cabinet 100, and the second temperature sensor 320 is disposed at the lower position of the other side wall of the interior of the wine cabinet 100.
That is, the first temperature sensor 310 and the second temperature sensor 320 may be spaced apart from each other by a relatively long distance, so as to detect the temperatures of different locations in the same storage space 111 in real time. This is because the temperatures within the wine cabinet 100 are typically unevenly distributed, such as where a large temperature deviation may occur between a middle location of one side wall and a lower location of the other side wall within the wine cabinet 100. The first temperature sensor 310 and the second temperature sensor 320 are arranged according to the specific positions, so that the temperature control accuracy of the whole wine cabinet 100 can be effectively improved. And when one temperature sensor fails, the other temperature sensor which works normally can be utilized for temperature control, so that the occurrence of accidents of freezing wine is avoided, and further, larger economic loss is avoided. In other embodiments, the first temperature sensor 310 and the second temperature sensor may be disposed at other positions, so long as the first temperature sensor and the second temperature sensor are not disposed at one position and are far apart, and may detect temperatures at different positions inside the wine cabinet 100.
In a preferred embodiment, the first temperature sensor 310 and the second temperature sensor 320 may also each be provided with a protective housing. The protective case may effectively prevent condensation from occurring on the surfaces of the first temperature sensor 310 and the second temperature sensor 320. For perfect cooperation with wine cabinet 100, first temperature sensor 310 and second temperature sensor 320 may be embedded, avoiding additional storage volume. In order to visually observe the temperature change of each area inside the wine cabinet 100, the wine cabinet 100 may be further provided with a display device for displaying the first temperature value and the second temperature value detected by the first temperature sensor 310 and the second temperature sensor 320 in real time.
The wine cabinet 100 is also provided with signaling means configured to: in case of failure of the first temperature sensor 310 or the second temperature sensor 320, a first prompt message is outputted to remind the user of timely maintenance. In addition, whether the first temperature value or the second temperature value is smaller than or equal to a preset temperature threshold value is judged, if yes, the refrigeration system is controlled to stop working, and the signal device is controlled to output second prompt information so as to remind a user of preventing the occurrence of wine freezing. Wherein the preset temperature threshold is a temperature threshold at which the wine is susceptible to freezing. The signal device can remind the user of the occurrence of the fault of the temperature sensor and can also effectively remind the user of the occurrence of the pre-freezing wine condition.
In a specific embodiment, the signaling device may be a display device as mentioned above, i.e. the relevant prompt information is output via the display device. In other embodiments, the signaling device may also be an audible device, such as a buzzer, that alerts the user by outputting a beep. When different conditions of the first prompt information and the second prompt information are output, different beeps can be emitted to distinguish.
The wine cabinet 100 may further include a control device 200, and fig. 2 is a block diagram of the control device 200 of the wine cabinet 100 according to one embodiment of the invention. The control device 200 comprises a processor 210 and a memory 220, wherein the memory 220 stores a control program 221, and the control program 221 is executed by the processor 210 for implementing the method for controlling the temperature of the wine cabinet according to any of the embodiments described below.
The embodiment also provides a temperature control method of the wine cabinet, and fig. 3 is a schematic diagram of the temperature control method of the wine cabinet according to one embodiment of the invention. The method of controlling the temperature of the wine cabinet may be performed using the wine cabinet 100 of any of the embodiments described above. As shown in fig. 3, the temperature control method of the wine cabinet sequentially performs the following steps:
step S302, a first temperature value detected by a first temperature sensor 310 and a second temperature value detected by a second temperature sensor 320 are obtained;
step S304, judging whether the first temperature sensor 310 and the second temperature sensor 320 are both working normally, if yes, executing step S306;
step S306, determining the actual temperature inside the wine cabinet 100 according to the first temperature value and the second temperature value, and controlling the refrigeration system of the wine cabinet 100 according to the actual temperature.
In the above steps, the first temperature sensor 310 and the second temperature sensor 320 are respectively disposed at different positions inside the wine cabinet 100 in step S304 to detect the actual temperatures at the different positions. Moreover, the first temperature sensor 310 and the second temperature sensor 320 may be thermal resistance sensors, and the principle of measuring temperature of the thermal resistance sensors is that: the resistance of the thermal resistor changes along with the temperature change, and the temperature can be obtained by measuring the resistance of the resistor. And, the resistance and the temperature may be inversely related, i.e., the larger the resistance, the lower the temperature; the smaller the resistance, the higher the temperature.
Therefore, in this embodiment, the first temperature sensor 310 and the second temperature sensor 320 may obtain the resistance value of the resistor through the AD sampling circuit, so as to obtain the first temperature value and the second temperature value. Specifically, in step S302, acquiring the first temperature value detected by the first temperature sensor 310 and the second temperature value detected by the second temperature sensor 320 may include: obtaining a first resistance value by using a circuit of the first temperature sensor 310, and determining a first temperature value according to the first resistance value; the second resistance value is obtained by the circuit of the second temperature sensor 320, and the second temperature value is determined according to the second resistance value.
When the obtained resistance value is abnormal, for example, the resistance value is close to zero or close to infinity, it can be determined that the first temperature sensor 310 or the second temperature sensor 320 has failed. Specifically, if the resistance value is close to zero, the temperature sensor is indicated to be short-circuited; if the resistance value is close to infinity, the temperature sensor is indicated to be disconnected. Therefore, the determining in step S304 whether the first temperature sensor 310 and the second temperature sensor 320 both operate normally may specifically include: judging whether the first resistance value or the second resistance value is close to zero or infinity; and if not, determining that both the first temperature sensor 310 and the second temperature sensor 320 are operating normally. For example, if the first resistance value is close to zero, it may be determined that the first temperature sensor 310 has a short circuit fault; if the first resistance value is close to infinity, it may be determined that the first temperature sensor 310 is out of circuit. Likewise, if the second resistance value is close to zero, it may be determined that the second temperature sensor 320 has a short circuit fault; if the second resistance value is close to infinity, it can be determined that the second temperature sensor 320 has an open circuit fault.
In the case where the first temperature sensor 310 fails and the second temperature sensor 320 operates normally, the refrigeration system may be controlled according to the second temperature value. In the case where the first temperature sensor 310 is operating normally and the second temperature sensor 320 is malfunctioning, the refrigeration system may be controlled according to the first temperature value.
The step of determining the actual temperature inside the wine cabinet 100 according to the first temperature value and the second temperature value in step S306 may include: according to t=k 1 *T 1 +k 2 *T 2 Calculating to obtain an actual temperature, wherein T is the actual temperature, k 1 For the first preset coefficient, T 1 At a first temperature value, k 2 For the second preset coefficient, T 2 Is the second temperature value. A first preset coefficient k 1 And a second preset coefficient k 2 The preset parameters are preset, specifically, the two preset coefficients can be determined through multiple experiments, so that the obtained actual temperature is closer to the average temperature in the wine cabinet 100, and the actual temperature condition in the wine cabinet 100 can be reflected.
The temperature control method of the wine cabinet of the present embodiment, wherein the first temperature sensor 310 and the second temperature sensor 320 are respectively disposed at different positions inside the wine cabinet 100, and the temperature control method includes: acquiring a first temperature value detected by a first temperature sensor 310 and a second temperature value detected by a second temperature sensor 320; judging whether the first temperature sensor 310 and the second temperature sensor 320 are both operating normally; and if so, determining the actual temperature inside the wine cabinet 100 according to the first temperature value and the second temperature value, and controlling the refrigerating system of the wine cabinet 100 according to the actual temperature, wherein compared with the scheme of arranging a sensor inside the wine cabinet 100, the double-sensor is arranged inside the wine cabinet 100, and the comprehensively obtained temperature is closer to the actual temperature inside the wine cabinet 100, so that the temperature control reliability of the wine cabinet 100 is effectively improved, the high-precision monitoring of the temperature inside the wine cabinet 100 can be realized, the refrigerating system is ensured to be timely started, and the storage requirement of wine products is met.
In some alternative embodiments, the wine cabinet 100 can achieve higher technical effects by further optimizing and configuring the above steps, and the following describes in detail the temperature control method of the wine cabinet according to this embodiment in combination with the description of an alternative execution flow of this embodiment, where this embodiment is merely illustrative of the execution flow, and when implementing, the execution sequence and the operation condition of some steps may be modified according to the specific implementation requirement. FIG. 4 is a detailed flow chart of a method of controlling the temperature of a wine cabinet according to one embodiment of the invention. The temperature control method of the wine cabinet comprises the following steps:
step S402, a first resistance value is obtained by using a circuit of the first temperature sensor 310, a first temperature value is determined according to the first resistance value, a second resistance value is obtained by using a circuit of the second temperature sensor 320, and a second temperature value is determined according to the second resistance value;
step S404, judging whether the first resistance value or the second resistance value is close to zero or infinity, if yes, executing step S414, otherwise, executing step S406;
step S406, determining that both the first temperature sensor 310 and the second temperature sensor 320 are operating normally;
step S408, judging whether the first temperature value or the second temperature value is less than or equal to a preset temperature threshold, if yes, executing step S416, otherwise, executing step S410;
step S410, calculating an actual temperature according to t=k1×t1+k2×t2;
step S412, controlling the refrigeration system of the wine cabinet 100 according to the actual temperature;
step S414, determining that the first temperature sensor 310 or the second temperature sensor 320 fails, and outputting a first prompt message by the control signal device to remind the user of timely maintenance;
and S416, controlling the refrigeration system to stop working, and controlling the signal device to output second prompt information so as to remind a user of the occurrence of wine freezing.
In the above step, in step S404, it is determined whether the first resistance value or the second resistance value is close to zero or infinity, and if yes, step S414 is performed if the first resistance value or the second resistance value is close to zero or infinity: it is determined that the first temperature sensor 310 or the second temperature sensor 320 is malfunctioning, and the control signal device outputs first prompt information to remind a user of timely maintenance. Specifically, if the first resistance value is close to zero or infinity, it may be determined that the first temperature sensor 310 is malfunctioning. Likewise, if the second resistance value is close to zero or infinity, it may be determined that the second temperature sensor 320 is malfunctioning. The temperature sensor with the fault can be reminded to the user by outputting the first prompt information so as to maintain in time. In case of a failure of one temperature sensor, the temperature control can be performed according to the other temperature sensor that is operating normally. If both temperature sensors fail, the first prompt message output is emergency message, and the emergency prompt user cannot perform normal temperature control on the wine cabinet 100, so that the user can find out measures in time.
In step S408, it is determined whether the first temperature value or the second temperature value is less than or equal to the preset temperature threshold, and if yes, step S416 is performed: and controlling the refrigeration system to stop working, and controlling the signal device to output second prompt information so as to remind a user of preventing the occurrence of wine freezing. Wherein the preset temperature threshold is a temperature threshold at which the wine is susceptible to freezing. And under the condition that any one of the temperature sensors detects that the temperature value is smaller than or equal to a preset temperature threshold value, the condition that wine is frozen is indicated to be likely to occur, and the refrigeration system is controlled to stop working at the moment so as to avoid the condition that wine is frozen. And the second prompt information is output through the signal device so as to remind the user of preventing the occurrence of the frozen wine condition, and the measures are convenient to take in time. The signal device can remind the user of the occurrence of the fault of the temperature sensor and can also effectively remind the user of the occurrence of the pre-freezing wine condition.
If the determination result in step S408 is no, step S410 is executed: the actual temperature is calculated as t=k1×t1+k2×t2. Wherein T is the actual temperature, k 1 For the first preset coefficient, T 1 At a first temperature value, k 2 For the second preset coefficient, T 2 Is the second temperature value. A first preset coefficient k 1 And a second preset coefficient k 2 The preset parameters are preset, specifically, the two preset coefficients can be determined through multiple experiments, so that the obtained actual temperature is closer to the average temperature in the wine cabinet 100, and the actual temperature condition in the wine cabinet 100 can be reflected.
Step S412 specifically may include controlling the refrigeration system of the wine cabinet 100 according to the actual temperature: judging whether the actual temperature is greater than or equal to a preset starting temperature; and if so, controlling the refrigeration system to start working. The step of controlling the refrigeration system of the wine cabinet 100 according to the actual temperature may further include: judging whether the actual temperature is less than or equal to a preset shutdown temperature; and if so, controlling the refrigeration system to stop working.
