[0063] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0064] Example 1

[0065] The storage devices currently on the market can only heat the left and right doors at the same time when condensation occurs on the double-sided glass doors. They cannot selectively heat according to the actual condensation situation, which results in high power consumption.

[0066] In view of the problem that the storage device in the prior art can only heat the left and right doors at the same time and cannot selectively heat according to the actual condensation situation, resulting in high power consumption, this embodiment provides an electric heating device applied to the storage device. Figure 1 is a structural diagram of a storage device according to an embodiment of the present invention, such as Figure 1 As shown, the storage device includes a body 1 , a first cabinet door 21 , and a second cabinet door 22 .

[0067] Figure 2 is a structural diagram of an electric heating device according to an embodiment of the present invention, as shown in Figure 2 As shown, the electric heating device comprises:

[0068] The first electric heating film 31 is arranged on the first cabinet door 21 of the storage device, and its first terminal is connected to the positive pole of the power supply, and its second terminal is connected to the first terminal A of the switching module 4, and the first electric heating film 31 is used to heat the first cabinet door 21; the second electric heating film 32, whose first terminal is connected to the negative pole of the power supply, is arranged on the second cabinet door 22 of the storage device, and its second terminal is connected to the second terminal B of the switching module, and the second electric heating film 32 is used to heat the second cabinet door 22; the switching module 4, whose third terminal C is connected to the positive pole of the power supply, and its fourth terminal D is connected to the negative pole of the power supply, is used to control the power supply of the first electric heating film 31 and / or the second electric heating film 32.

[0069] The electric heating device of this embodiment is provided with two electric heating films, which are respectively arranged on the two cabinet doors of the storage device. When the condensation value on one of the cabinet doors exceeds the first threshold value, the corresponding electric heating film is controlled to be powered on by controlling the conduction state of the switching module. When the condensation values ​​on the two cabinet doors exceed the first threshold value, the two electric heating films are controlled to be powered on at the same time. It is possible to control the power-on of the corresponding electric heating film according to the actual condensation situation, avoid unnecessary consumption of electric energy, and achieve the purpose of saving energy.

[0070] When the condensation values ​​of the two cabinet doors exceed the first threshold and the condensation situation is serious, it is necessary to increase the voltage of each electric heating film, that is, control the two electric heating films in parallel to achieve rapid condensation removal; and when the condensation values ​​of the two cabinet doors exceed the first threshold and the condensation situation is relatively mild, applying a smaller voltage to each electric heating film can meet the condensation removal requirements, that is, control the two electric heating films in series, which can save electricity to the greatest extent. Therefore, the above-mentioned switching module is also used to control the connection relationship between the first electric heating film and the second electric heating film.

[0071] The working principle of this embodiment is as follows:

[0072] Single door heating mode:

[0073] When the condensation value of the first cabinet door 21 exceeds the first threshold value, the conduction relationship inside the switching module 4 changes, so that the first terminal A and the fourth terminal D are connected, and the second terminal B and the third terminal C are disconnected, and the first electric heating film 31 on the first cabinet door 21 is controlled to be energized separately;

[0074] When the condensation value of the second cabinet door 22 exceeds the first threshold, the internal conduction relationship of the switching module 4 changes, so that the second terminal B and the third terminal C are conductive, and the first terminal A and the fourth terminal D are disconnected, and the second electric heating film 32 on the second cabinet door 22 is individually controlled to be energized.

[0075] Double door heating mode:

[0076] When the condensation values ​​of the first cabinet door 21 and the second cabinet door 22 both exceed the first threshold value, and the door condensation sensor 5 recognizes that the condensation value has not reached the second threshold value, the circuit switch is controlled so that the first terminal A and the second terminal B are connected, and the third terminal C and the fourth terminal D are disconnected, and the first electric heating film 31 on the first cabinet door 21 and the second electric heating film 32 on the second cabinet door 22 are energized in series;

[0077] When the condensation values ​​of the first cabinet door 21 and the second cabinet door 22 both exceed the first threshold value, and the door condensation sensor 5 recognizes that the condensation value reaches the second threshold value, the circuit switch is controlled to make the first terminal A and the fourth terminal D conductive, the second terminal B and the third terminal C conductive, and the first electric heating film 31 on the first cabinet door 21 and the second electric heating film 32 on the second cabinet door 22 energized in parallel.

[0078] Figure 3 : is an internal structure diagram of a switching module according to an embodiment of the present invention, such as Figure 3 As shown, the switching module 4 includes: a first switch S1, a first end of which is connected to the first terminal of the switching module, and a second end of which is connected to the fourth terminal of the switching module; a second switch S2, a first end of which is connected to the second terminal of the switching module, and a second end of which is connected to the third terminal of the switching module; a third switch S3, a first end of which is connected to the first terminal of the switching module, and a second end of which is connected to the second terminal of the switching module.

[0079] When the condensation value of the first cabinet door 21 exceeds the first threshold, the switch S1 is controlled to be closed, and the switches S2 and S3 are disconnected, so that the first terminal A and the fourth terminal D are connected, and the second terminal B and the third terminal C are disconnected, and the first electric heating film 31 on the first cabinet door 21 is controlled to be energized separately;

[0080] When the condensation value of the second cabinet door 22 exceeds the first threshold, the control circuit switch S2 is closed, and the switch S1 and switch S3 are opened, so that the second terminal B and the third terminal C are connected, and the first terminal A and the fourth terminal D are disconnected, and the second electric heating film 32 on the second cabinet door 22 is controlled to be energized separately;

[0081] Double door heating mode:

[0082] When the condensation values ​​of the first cabinet door 21 and the second cabinet door 22 simultaneously exceed the first threshold value, and the door condensation sensor 5 recognizes that the condensation value has not reached the second threshold value, the control circuit switch S3 is closed, and the switches S1 and 2 are disconnected, so that A and B are connected, C and D are disconnected, and the electric heating films 3 of the first cabinet door 21 and the second cabinet door 22 are energized in series;

[0083] When the condensation values ​​of the first cabinet door 21 and the second cabinet door 22 simultaneously exceed the first threshold value, and the door condensation sensor 5 recognizes that the condensation value reaches the second threshold value, the control circuit switches S1 and S2 are closed, and the switch S3 is opened, so that the first terminal A and the fourth terminal D are conductive, and the second terminal B and the third terminal C are conductive, and the electric heating films 3 of the first cabinet door 21 and the second cabinet door 22 are energized in parallel.

[0084] In order to detect the condensation state of the first cabinet door 21 and the second cabinet door 22 respectively, Figure 3 As shown, the electric heating device further includes: a first condensation sensor 51, which is arranged on the first cabinet door 21 of the storage device, and is used to detect whether the condensation value of the first cabinet door 21 exceeds a first threshold value; a second condensation sensor 52, which is arranged on the second cabinet door 22 of the storage device, and is used to detect whether the condensation value of the second cabinet door 22 exceeds the first threshold value; wherein, the condensation value is used to characterize the severity of the condensation, and the larger the condensation value, the higher the severity of the condensation.

[0085] If used to open the door, the electric heating film continues to perform electric heating, which may cause burns to the user. Therefore, when the cabinet door is opened, the heating should be stopped. In order to detect whether the cabinet door is opened, the above-mentioned electric heating device also includes: a first door opening sensor 61, which is arranged on the contact surface between the first cabinet door 21 and the storage device body, and is used to detect whether the first cabinet door 21 is opened; a second door opening sensor 62, which is arranged on the contact surface between the second cabinet door 22 and the storage device body, and is used to detect whether the second cabinet door 22 is opened.

[0089] Example 3

[0090] This embodiment provides a control method, which is applied to the above-mentioned electric heating device. Figure 5 is a flow chart of a control method according to an embodiment of the present invention, as shown in Figure 5 As shown, the control method includes:

[0091] S101, detecting whether the condensation values ​​of a first cabinet door and a second cabinet door of a storage device exceed a first threshold.

[0092] S102, controlling the conduction state of the switching module according to the detection results of the condensation values ​​of the first cabinet door and the second cabinet door, and further controlling the power-on state of the first heating film and the second heating film.

[0093] The control method of this embodiment, when the condensation value on one of the cabinet doors exceeds the first threshold value, controls the corresponding electric heating film to be powered on by controlling the conduction state of the switching module; when the condensation values ​​on both cabinet doors exceed the first threshold value, controls the two electric heating films to be powered on at the same time, thereby enabling the power-on of the corresponding electric heating film to be controlled according to the actual condensation situation, avoiding unnecessary consumption of electric energy, and achieving the purpose of saving energy.

[0094] Specifically, in order to save energy, the conduction state of the switching module is controlled according to the detection results of the condensation values ​​of the first cabinet door and the second cabinet door, and then the power-on state of the first heating film and the second heating film is controlled, including: if only the condensation value of the first cabinet door exceeds the first threshold value, the conduction state of the switching module is controlled to switch to the first conduction state, and then the first heating film is controlled to be powered on alone; if only the condensation value of the second cabinet door exceeds the first threshold value, the conduction state of the switching module is controlled to switch to the second conduction state, and then the second heating film is controlled to be powered on alone.

[0095] When the condensation values ​​of both cabinet doors exceed the first threshold and the condensation situation is serious, it is necessary to increase the voltage of each electric heating film, that is, control the two electric heating films in parallel to achieve rapid condensation removal; and when the condensation values ​​of both cabinet doors exceed the first threshold and the condensation situation is relatively mild, applying a smaller voltage to each electric heating film can meet the condensation removal requirements, that is, control the two electric heating films in series, which can save electricity to the greatest extent. Therefore, in order to control the voltage applied to the electric heating film according to the severity of condensation, and then control the heating temperature, if the condensation values ​​of the first cabinet door and the second cabinet door both exceed the first threshold, the connection relationship between the first heating film and the second heating film is controlled according to the condensation value, wherein the condensation value is used to characterize the severity of condensation, and the larger the condensation value, the higher the severity of condensation.

[0096] Specifically, the connection relationship between the first heating film and the second heating film is controlled according to the condensation value, including: judging whether the condensation value reaches the second threshold value; if not, controlling the conduction state of the switching module to switch to the third conduction state, thereby controlling the first heating film and the second heating film to be energized in series; if yes, controlling the conduction state of the switching module to switch to the fourth conduction state, thereby controlling the first heating film and the second heating film to be energized in parallel.

[0097] As described above, the switching module 4 includes: a first switch S1, a first end of which is connected to the first terminal A of the switching module 4, and a second end of which is connected to the fourth terminal D of the switching module 4; a second switch S2, a first end of which is connected to the second terminal B of the switching module, and a second end of which is connected to the third terminal C of the switching module; a third switch S3, a first end of which is connected to the first terminal A of the switching module 4, and a second end of which is connected to the second terminal B of the switching module. Therefore, controlling the conduction state of the switching module to switch to the first conduction state includes: controlling the first switch S1 of the switching module to be turned on; controlling the conduction state of the switching module to switch to the second conduction state includes: controlling the second switch S2 of the switching module to be turned on; controlling the conduction state of the switching module to switch to the third conduction state includes: controlling the third switch S3 of the switching module to be turned on; controlling the conduction state of the switching module to switch to the fourth conduction state includes: controlling the first switch S1 and the second switch S2 of the switching module to be turned on at the same time.

[0098] If used to open the door, the electric heating film continues to perform electric heating, which may cause burns to the user. Therefore, when the cabinet door is opened, the heating should be stopped. Therefore, the conduction state of the switching module is controlled according to the detection results of the condensation values ​​of the first cabinet door and the second cabinet door, and then the power-on state of the first heating film and the second heating film is controlled. The above-mentioned control method also includes: judging whether the first cabinet door and the second cabinet door are opened; if the first cabinet door is opened, controlling the first switch to be disconnected; if the second cabinet door is opened, controlling the second switch to be disconnected; if the first cabinet door and the second cabinet door are both opened, controlling the first switch, the second switch, and the third switch to be disconnected.
