Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a refrigerator with an adaptive facial mask function and a control method thereof. Background Art

[0002] As people's living standards continue to improve, more and more families are equipped with refrigerators to meet the needs of daily life, and the functional requirements of refrigerators are getting higher and higher. For example, refrigerators are used to store facial masks. In order to maintain the elasticity and humidity of facial masks, a relatively temperature and humidity environment is now built in the refrigerator for facial masks to be stored.

[0003] An existing electronically controlled refrigerator with an adaptive facial mask function comprises a heater arranged at a door body, an infrared receiver, an infrared emitter, a facial mask storage area and the like.

[0004] However, due to the thickness of the door structure, if the heater is far away from the mask storage area, it cannot meet the actual needs; because the heater is 220V, it needs to meet the requirements of GB4706.1 (double-layer protection). If a DC heater is used, the power supply power needs to be increased, and the power supply cost will be greatly increased; therefore, an electronically controlled refrigerator with an adaptive mask function is needed to not only meet the requirements of creating an environment with appropriate relative temperature and humidity for mask storage, but also save energy consumption and reduce manufacturing costs.

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0038] Because in some technologies, the refrigerator with adaptive mask function is limited by the thickness of the refrigerator door structure, and the heater is far away from the mask area, which cannot meet the actual needs; because the heater is 220V, it is necessary to meet the requirements of GB4706.1 (double-layer protection). If a DC heater is used, the power supply power needs to be increased, and the power supply cost will be greatly increased; so it is necessary to have a refrigerator that can not only meet the requirements of the mask in a relatively temperature and humidity environment for the mask to be stored, but also save energy consumption and reduce manufacturing costs. In order to solve this technical problem, this application provides a refrigerator with adaptive mask function and a control method. The following is a description of a refrigerator with adaptive mask function and a control method:

[0039] Depend on Figure 1It can be seen that the first aspect of the present application provides a refrigerator with an adaptive facial mask function, including: a facial mask holding box 1, which is arranged in the refrigerator; an infrared sensor 2, which is arranged on the refrigerator door, and is configured to send infrared rays to the facial mask holding box 1 and determine whether there is a facial mask in the facial mask holding box 1, and transmit the information whether there is a facial mask in the facial mask holding box 1 as an instruction; a PTC heater 3, which is arranged in the facial mask holding box 1, and is configured to heat the facial mask holding box 1; a control board 4, which is arranged in the facial mask holding box 1, is communicatively connected to the infrared sensor 2, is electrically connected to the PTC heater 3, and is configured to receive the instruction of the infrared sensor 2 to determine whether to control the PTC heater 3 to heat; a display panel 5, which is arranged on the refrigerator door, is electrically connected to the PTC heater 3, and is configured to display the temperature in the facial mask holding box and whether the PTC heater 3 is turned on.

[0040] In this embodiment, the present application provides a PTC heater 3 to solve the problem that the existing aluminum foil heater cannot be installed in a refrigerator with an adaptive mask function due to structural limitations and the cost of using a DC heater will be greatly increased. By placing a mask in the mask holding box 1, the infrared sensor 2 emits infrared rays into the mask holding box 1 and receives them to determine whether there is a mask in the mask holding box 1, and transmits information instructions to the control board 4 to control the PTC heater 3 to heat the mask holding box according to the temperature in the mask holding box 1, thereby maintaining the humidity of the mask.

[0041] It can be understood that the PTC heater 3 can be arranged on the door of the refrigerator without being affected by the structure. Compared with the DC heater, it can not only achieve its heating efficiency but also be cheaper. Compared with the traditional refrigerator using aluminum foil heater, the PTC heater has the characteristics of high heating effect and long life.

[0042] Depend on Figure 1 It can be seen that the infrared sensor 2 includes: an infrared transmitter 21, configured to emit infrared rays into the mask holding box 1; an infrared receiver 22, configured to receive infrared information emitted by the infrared transmitter 21; a processing unit 23, which is communicatively connected to the infrared receiver 22, and is configured to determine whether a mask is placed in the mask holding box 1 based on the infrared information emitted by the infrared transmitter 21 received by the infrared receiver 22, and transmit the information on whether a mask is placed in the mask holding box 1 to the control board 4.

[0043] In this embodiment, the infrared transmitter 21 of the infrared sensor 2 is used to emit infrared rays into the mask holding box 1. The infrared rays emitted by the infrared transmitter 21 are received by the infrared receiver 22, and the infrared information of the infrared receiver 22 is received by the processing unit 23 to obtain whether a mask is placed in the mask holding box 1, and the information is transmitted to the control board 4 for the next operation.

[0044] Among them, the infrared transmitter 21 is an element on the infrared sensor 2 used to transmit infrared rays to the mask holding box 1, the infrared receiver 22 is an element used to receive infrared rays emitted by the infrared transmitter 21, and the processing unit is a program element used to receive the infrared information received by the infrared receiver 22, and determine whether a mask is placed in the mask holding box 1 and transmit it as instruction information to the control board 4.

[0045] have Figure 1 It can be seen that the control board 4 includes: a receiving unit 41, configured to receive the command information of the infrared sensor 2; a judgment unit 42, which is communicated with the receiving unit 41 and is configured to judge whether to control the PTC heater 3 for heating according to the command information of the infrared sensor 2 received by the receiving unit 41, and generate an instruction for adjusting the heating mode of the PTC heater 3 according to the temperature in the facial mask storage box 1; a sending unit 43, which is communicated with the judgment unit 42 and is configured to receive the command information of the judgment unit 42 and send it to the PTC heater 3.

[0046] In this embodiment, the receiving unit of the control panel 4 is used to receive the command information of the infrared sensor 2, and the judging unit 42 is used to make a judgment based on the command information of the infrared sensor 2 received by the receiving unit 41. If the information indicates that there is no mask in the mask holding box 1, the judging unit 42 controls the PTC heater 3 not to heat. If the information indicates that a mask is placed in the mask holding box 1, the judging unit 42 controls the PTC heater 3 to heat, and adjusts the heating mode of the PTC heater 3 according to the temperature in the mask holding box 1 and generates a control instruction, which is sent by the sending unit 43 to the PTC heater 3 to heat the mask storage box 1.

[0047] Among them, the receiving unit 41 is a component in the control board 4 used to receive the command information of the infrared sensor 2, the judging unit is a program component used to judge whether to control the PTC heater 3 for heating according to the command information of the infrared sensor 2 and generate command information used to control the heating of the PTC heater 3, and the sending unit 43 is a component used to send the command information of the judging unit 42 to the PTC heater 3.

[0048] Depend on Figure 1 It can be seen that the refrigerator with adaptive mask function also includes: a buzzer 6, which is arranged on the refrigerator door, communicates with the infrared sensor 2, and is configured to alarm according to the instruction information of the infrared sensor 2. If there is no mask in the mask holding box 1, the buzzer 6 will sound an alarm and turn off the PTC heater 3.

[0049] In this embodiment, the buzzer 6 is a device for detecting whether there is a fault in the equipment. Under normal circumstances, if all the masks in the mask holding box 1 are taken out, the infrared sensor 2 determines that there is no mask placed in the mask holding box 1, and the buzzer 6 will sound an alarm to prompt and turn off the PTC heater 3. If a mask is placed in the mask holding box 1, the buzzer 6 also issues a warning, which proves that the device in the refrigerator with adaptive mask function may be damaged and determines whether the PTC heater 3 is damaged based on whether the PTC heater 3 displayed on the display panel 5 is turned on.

[0050] Depend on Figure 2 It can be seen that the second aspect of the present application provides a control method for an electronically controlled refrigerator with an adaptive facial mask function, which is applied to the refrigerator with an adaptive facial mask function, and includes:

[0051] S110, sending an information instruction acquired by the infrared sensor to the control board to determine whether a mask is placed in the mask storage box;

[0052] S120, if a facial mask is placed in the facial mask storage box, the control board generates an instruction for adjusting the heating mode of the PTC heater according to the temperature in the facial mask storage box;

[0053] S130, heating the inside of the facial mask containing box based on the instruction information received by the PTC heater from the control board;

[0054] S140, if the temperature inside the mask holding box is higher than 15°C, the PTC heater heats for 6 minutes, stops for 4 minutes, cycles 3 times, and then turns off the heater; if the temperature inside the mask holding box is lower than 15°C, the PTC heater heats for 5 minutes, stops for 4 minutes, cycles 3 times, and then turns off the heater.

[0055] It can be understood that the PTC heater 3 adjusts its own heating mode according to the temperature in the mask holding box 1, which can maximize energy saving while ensuring that the temperature in the mask holding box 1 is met to maintain the humidity of the mask.

[0056] Depend on Figure 2 It can be seen that the control method of the electronically controlled refrigerator with an adaptive facial mask function further includes:

[0057] S150, based on the instruction information obtained by the infrared sensor, if there is no mask in the mask storage box, the buzzer will sound an alarm and turn off the PTC heater.

[0058] It can be understood that, through the cooperation of the buzzer 6 and the display panel 5, the PTC heater 3 can be self-checked to prevent the mask from losing moisture due to the PTC heater 3 being damaged without knowing it.

[0059] In this embodiment, the infrared sensor does not perform infrared transmission and reception when the refrigerator door is opened, and the PTC heater 3 also stops working. This is because when the refrigerator door is opened, heat in the refrigerator will be lost. Even if the PTC heater 3 heats the mask holding box 1, heat will be lost. Therefore, to ensure efficient use of energy, when the refrigerator door is opened, the infrared sensor 2 does not work, and the PTC heater 3 does not heat either. It waits until the refrigerator door is closed before reheating, thereby reducing energy consumption.

[0060] In this embodiment, the PTC heater has two heating modes. One heating mode is that when the temperature inside the mask holding box is higher than 15°C, the PTC heater heats for 6 minutes, stops for 4 minutes, cycles 3 times, and then turns off the heater. The other heating mode is that when the temperature inside the mask holding box is lower than 15°C, the PTC heater heats for 5 minutes, stops for 4 minutes, cycles 3 times, and then turns off the heater. By setting two different heating powers, energy consumption can be saved to the maximum extent.

[0061] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
