In the description of the present invention, it should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected unless otherwise explicitly stated or limited. Either mechanically or electrically. Either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1 to 9, a microwave water heater 100 according to an embodiment of the present invention includes a main body 10, a microwave heating system, and a water pipe system.

The body 10 includes a thermally conductive bladder 11. The inner container 11 is formed with a heating chamber 111. The microwave heating system comprises a microwave generator 21. The microwave generator 21 serves to emit microwaves to the heating chamber 111. The water line system comprises a heat-conducting heating water line 31 arranged around an outer wall 112 of the inner container 11.

In the microwave water heater 100 according to the embodiment of the present invention, the heating water pipe 31 is wound around the outer wall 112 of the inner container 11, so that the structure inside the inner container 11 is simplified, and the difficulty in installing the microwave water heater 100 is reduced.

In operation, the inner container 11 conducts heat, and the heat-conducting heating water pipe 31 is wound on the outer wall 112 of the inner container 11, so that water in the heating chamber 111 can be heated by the microwave generator 21, and then the heat of the water in the heating chamber 111 is conducted to the water in the heating water pipe 31 by the heat-conducting inner container 11, thereby completing heating of the water in the heating water pipe 31.

The number of the inner containers 11 disposed in the body 10 may be set according to specific situations, for example, the number of the inner containers 11 may be 1 or 2. The heating mode of the water in the inner container 11 can be kept consistent. The microwave heating system can be a single set of microwave heating system or a double set of microwave heating system, and can be set according to specific conditions. For example, when the microwave water heater 100 includes two inner containers 11, the two inner containers 11 may be separately disposed, and then a dual microwave heating system is disposed outside the inner containers 11, and the two microwave generators 21 respectively heat the corresponding heating chambers 111.

Meanwhile, the inner container 11 is made of a heat conductive material, for example, the inner container 11 is made of a metal material. Of course, when the inner container 11 is made of a metal material, water may be contained in the heating chamber 111 for a long time, so that the water may be prevented from corroding the inner container 11 by coating a waterproof layer (not shown) on the inner wall of the heating chamber 111. The waterproof layer may be formed of a waterproof paint.

Also, it can be understood that if the inner container 11 is made of a metal material, the detection device 115 can be further configured to detect the ion concentration of the water in the heating chamber 111 to prevent the water from corroding the inner container 11, and particularly to prevent the water from electrochemically corroding the inner container 11.

For example, in the example shown in fig. 9, the microwave water heater 100 is provided with a detection means 115 for detecting the pH value of the water in the heating chamber 111 in real time. The microwave water heater 100 also includes a display device 116 electrically connected to the detection device 115. The display device 116 is used for displaying the value of the pH value of the water in the heating chamber 111 in real time. When the pH of the water in the heating chamber 111 is less than or equal to a first set threshold (e.g., pH less than or equal to 6), the user may directly replace the water in the heating chamber 111 to prevent electrochemical corrosion. Likewise, when the pH of the water in the heating chamber 111 is greater than or equal to the second set threshold (e.g., pH greater than or equal to 12), the user may also directly replace the water in the heating chamber 111 to prevent scaling in the heating chamber 111. Here, the first set threshold and the second set threshold may be set as appropriate, and may be set according to the type of metal material constituting the inner container 11, for example.

The heating water pipe 31 is made of a heat conductive material, and the heating water pipe 31 is made of a metal material, for example. It is understood that, in order to increase the contact area between the heating water pipe 31 and the outer wall 112 of the inner container 11, the side of the heating water pipe 31 contacting the outer wall 112 of the inner container 11 may be flat, so that the contact area between the heating water pipe 31 and the outer wall 112 is large, and thus a large heat transfer area is provided between the heating water pipe 31 and the outer wall 112. Also, it can be understood that a groove (not shown) matching the shape of the heating water pipe 31 may be formed on the outer wall 112 of the inner container 11, and the groove may form a half-wrapping shape to the heating water pipe 31, so that the contact area between the heating water pipe 31 and the outer wall 112 may be increased, and the heat loss between the heating water pipe 31 and the outer wall 112 may be reduced, thereby improving the heat conduction efficiency between the heating water pipe 31 and the outer wall 112. In one embodiment, the inner container 11 is of an integrally molded construction. Thus, the inner container 11 can be easily manufactured.

In one example, the inner container 11 is a cylindrical tank. Thus, the manufacturing is convenient, and the price is cheaper.

In one embodiment, the volume of the heating chamber 111 is less than or equal to 10L. In this way, the volume of the heating chamber 111 is appropriately sized, so that the amount of water filled in the heating chamber 111 is appropriate, thereby allowing the microwave generator 21 to complete heating of the water in the heating chamber 111 in a short time. This ensures that the microwave generator 100 can be heated more quickly by the action of the microwaves.

It should be noted that before the microwave water heater 100 is operated, a certain amount of water may be filled in the heating chamber 111 in advance, and then the microwaves may be directly emitted into the heating chamber 111 through the microwave generator 21 to heat the water in the heating chamber 111. Thus, heat generated by the water heated by the microwave can be directly conducted to the heating water pipe 31 through the liner 11, so that the water in the heating water pipe 31 can be heated in real time. The heating chamber 111 may be filled with water, or a part of the water may be filled in the heating chamber 111, which may be set according to specific situations, and only needs to be enough to sufficiently heat the water in the heating water pipe 31.

In one embodiment, the volume of the heating chamber 111 ranges from 4L to 8L. Thus, the microwave generator 21 can heat the water in the heating chamber 111 in a short time, and the water in the heating chamber 111 heated by the microwaves can be sufficiently heated in a short time.

In some examples, the heating chamber 111 has a volume of 4L, 5L, 5.5L, 6L, 7L, 7.5L, or 8L. It should be noted that the volume of the heating chamber 111 is not limited to the values listed in the above examples.

In one embodiment, the number of turns of the heating water pipe 31 around the outer wall 112 of the inner container 11 is greater than or equal to 2. In this way, the flow path of the heating water pipe 31 is long, and the contact area with the outer wall 112 is large, so that a large heat conduction area is provided between the heating water pipe 31 and the outer wall 112, thereby being capable of ensuring that the water in the heating water pipe 31 is sufficiently heated. Meanwhile, the heating water pipe 31 and the outer wall 112 have a large heat conducting area, so that the water flowing in the heating water pipe 31 can be heated quickly.

In some examples, the heating water pipe 31 is wound around the outer wall 112 of the inner container 11 for 2, 3, 4 or 5 turns. It should be noted that the number of turns of the heating water pipe 31 around the outer wall 112 of the inner container 11 is not limited to the values listed in the above examples.

In one embodiment, the water conduit system includes thermally conductive connecting water conduits 32. The connection water pipe 32 penetrates the heating chamber 111. One end of the connection water pipe 32 is located outside the heating chamber 111 and connected to one end of the heating water pipe 31. The other end of the connection water pipe 32 is located outside the heating chamber 111 and connected to the other end of the heating water pipe 31.

Thus, water can enter the connection water pipe 32 from one end of the heating water pipe 31, and can enter the other end of the heating water pipe 31 from the connection water pipe 32. Meanwhile, since the portion of the connecting water pipe 32 that conducts heat is located in the heating chamber 111, the water passing through the connecting water pipe 32 is heated by the microwave, so that the heating efficiency of the water in the heating water pipe 31, that is, the heating speed of the microwave water heater 100 can be improved.

In one embodiment, the connecting water tube 32 is closer to the top end 113 of the inner container 11 than the heating water tube 31.

Thus, the heating water pipe 31 can be ensured to be sufficiently wound on the outer wall 112 of the inner container 11 from bottom to top along the outer wall 112 of the inner container 11. Meanwhile, the connecting water pipe 32 has little influence on the structure of the inner container 11, and does not influence the water filled in the heating chamber 111. For example, when the connecting water pipe 32 is inserted into the heating chamber 111 so as to form a hole in the wall of the top end 113 of the inner container 11, the hole has a small influence on the water filling capacity of the heating chamber 111 because the hole formed in the inner container 11 is formed in the top end 113.

It should be noted that the "up and down" is based on the position state of the inner container 11 in the normal use state, for example, the position state shown in fig. 1.

In one example, one end of the connection water pipe 32 is connected to one end of the heating water pipe 31. The other end of the connecting water pipe 32 is an outer wall 112 penetrating one side of the inner container 11, then extends into the heating chamber 111, then penetrates out of the outer wall 112 of the other side of the inner container 11, and then is connected with the other end of the heating water pipe 31. A waterproof sealing element (not shown) is provided between the connecting water pipe 32 and the outer wall 112 of the inner container 11. The sealing member seals a gap between the water pipe 32 and the outer wall 112 of the inner container 11.

In one embodiment, the water line system includes a first inlet line 33 and a first outlet line 34. One end of the first water inlet pipe 33 penetrates through the side plate of the inner container 11 and is communicated with the heating chamber 111. One end of the first water outlet pipe 34 penetrates through the side plate of the inner container 11 and is communicated with the heating chamber 111. The microwave water heater 100 includes a first valve 40 and a second valve 41. The first valve 40 is installed on the first inlet pipe 33. A second valve 41 is mounted on the first outlet pipe 34. The first valve 40 is used to open or close the first inlet pipe 33. The second valve 41 is used to open or close the first outlet pipe 34.

Specifically, in some embodiments, when the heating chamber 111 is filled with water, the first inlet pipe 33 may be opened through the first valve 40, and the first outlet pipe 34 may be closed through the second valve 41, so that the water may enter the heating chamber 111 from the first inlet pipe 33. When the water level in the heating chamber 111 reaches the set water level, the first valve 40 may be directly closed. Microwaves are then emitted by the microwave generator 21 to heat the water in the heating chamber 111.

When the water in the heating chamber 111 needs to be discharged, the water in the heating chamber 111 can be discharged only by opening the first water outlet pipe 34 through the second valve 41. In this way, control of the inlet and outlet of water in the heating chamber 111 is achieved in a relatively simple manner. The "set water level" may be set as appropriate, and for example, in one example, when the heating chamber 111 is filled with water, the water level in the heating chamber 111 reaches a set position.

It will be appreciated that in order to avoid excessive water being retained in the first inlet pipe 33 or the first outlet pipe 34 and affecting the heating effect, a first valve 40 may be mounted on the end of the first inlet pipe 33 adjacent to the inner container 11, and a second valve 41 may be mounted on the end of the first outlet pipe 34 adjacent to the inner container 11.

The opening and closing modes of the first valve 40 and the second valve 41 may be manually or by program control, and may be set according to actual application conditions. When water enters the heating chamber 111, a vent hole (not shown) communicating with the outside may be formed at the top of the heating chamber 111 to allow the water to enter smoothly.

In one embodiment, the microwave water heater 100 includes a control device 50. The control device 50 is electrically connected to the first valve 40 and the second valve 41. The control device 50 controls the opening and closing states of the first valve 40 and the second valve 41. The control device 50 is electrically connected to the microwave generator 21. The control device 50 is used for controlling the operating state of the microwave generator 21.

Specifically, in some embodiments, when the heating chamber 111 is filled with water, that is, the microwave water heater 100 enters a water filling state, the control device 50 controls the first valve 40 to open so that water can enter the heating chamber 111 from the first water inlet pipe 33, controls the second valve 41 to close so that the first water outlet pipe 34 is disconnected from the heating chamber 111, and controls the microwave generator 21 to be in a closed state, that is, the microwave generator 21 cannot emit microwaves to the heating chamber 111. At this time, the water may directly enter the heating chamber 111 from the first water inlet pipe 33, and may not be discharged from the first water outlet pipe 34. When the water level in the heating chamber 111 reaches the set water level, the control device 50 controls the first valve 40 to close to disconnect the first water inlet pipe 33 from the heating chamber 111, and controls the second valve 41 to keep a closed state, at which time the heating chamber 111 stops water inlet, that is, the microwave water heater 100 exits the water filling state.

At this time, the control device 50 controls the microwave generator 21 to be turned on, that is, the microwave generator 21 may emit microwaves to the heating chamber 111. In this way, the control of the water inlet and outlet in the heating chamber 111 is achieved in a relatively simple manner, and the intelligent control of the two valves and the microwave generator 21 is achieved. It should be noted that the "set water level" may be set according to specific situations, for example, in one example, when the heating chamber 111 is filled with water or filled to half capacity, the water level in the heating chamber 111 reaches the set water level.

In one embodiment, the microwave water heater 100 includes a key 51. The control device 50 is electrically connected to the button 51. The control device 50 controls the microwave water heater 100 to enter the water filling state through the button 51. After the microwave water heater 100 enters the water-filling state, the control device 50 is used for controlling the first valve 40 to open so that the first water inlet pipe 33 is communicated with the heating chamber 111, and for controlling the second valve 41 to close so that the first water outlet pipe 34 is disconnected from the heating chamber 111.

Specifically, in some embodiments, after the user activates the button 51, the microwave water heater 100 enters a water-filled state, i.e., starts to fill the heating chamber 111 with water. At this time, the control device 50 controls the first valve 40 to be opened so that water can enter the heating chamber 111 through the first water inlet pipe 33, controls the second valve 41 to be closed so that the first water outlet pipe 34 is in a disconnected state from the heating chamber 111, and controls the microwave generator 21 to be in a closed state, that is, the microwave generator 21 cannot emit microwaves to the heating chamber 111. The water can now enter the heating chamber 111 directly from the first inlet pipe 33 and not flow out of the first outlet pipe 34. In this way, the control device 50 controls the water inlet state of the microwave water heater 100 through the key 51, so that the operation of the user is facilitated, and the operability of the microwave water heater 100 is improved.

In one embodiment, the microwave water heater 100 includes a water level sensing element 60. The water level detecting element 60 serves to detect the water level within the heating chamber 111. In this way, the actual water level in the heating chamber 111 can be detected by the water level detecting element 60, so that the condition of the water level in the heating chamber 111 can be grasped more accurately in a simpler manner.

In the embodiment shown in fig. 8, the control device 50 is electrically connected to the water level detecting element 60. The water level detecting element 60 can detect the real-time water level in the heating chamber 111 and can feed back the detection result to the control device 50 in the form of an electric signal. When the water level detecting element 60 detects that the water level in the heating chamber 111 reaches the set water level, the control device 50 can control the first valve 40 to close according to the detection result of the water level detecting element 60 so that the first water inlet pipe 33 is in a disconnected state from the heating chamber 111. At this time, the heating chamber 111 stops water feeding, i.e. the microwave water heater 100 exits the water filling state. It should be noted that the "set water level" may be set according to specific situations, for example, in one example, when the heating chamber 111 is filled with water or filled to half capacity, the water level in the heating chamber 111 reaches the set position.

In one embodiment, the water level detection member 60 includes a flow sensor (not shown). The flow sensor is mounted on the first inlet conduit 33. The flow sensor is used to detect the flow rate of water in the first water inlet pipe 33. The water level detecting member 60 detects the water level in the heating chamber 111 through a flow sensor. In this manner, the water level inside the heating chamber 111 can be determined by detecting the flow rate of water entering the heating chamber 111, thereby achieving detection of the water level inside the heating chamber 111 in a simpler manner. Meanwhile, the accuracy of the value of the water level in the heating chamber 111 obtained by the detection means of the flow sensor is high.

For example, when the flow sensor is installed on the first inlet pipe 33 and water enters the heating chamber 111 through the first inlet pipe 33, the flow sensor can detect a real-time flow rate of water entering the heating chamber 111 through the first inlet pipe 33 and can accumulate the amount of water entering the heating chamber 111 according to the real-time flow rate of water entering the heating chamber 111 through the first inlet pipe 33, so that the water level in the heating chamber 111 can be determined.

In one embodiment, the water level detecting element 60 includes a liquid level sensor (not shown). The level sensor is mounted within the heating chamber 111. The water level detecting element 60 detects the water level in the heating chamber 111 by a liquid level sensor. In this way, the level sensor can directly detect the water level inside the heating chamber 111, which enables detection of the water level inside the heating chamber 111 in a simple manner.

In one embodiment, the water line system includes a second inlet line 35 and a second outlet line 36. The second water inlet pipe 35 is connected to one end of the heating water pipe 31. The second water outlet pipe 36 is connected with the other end of the heating water pipe 31. The microwave water heater 100 includes a third valve 42 and a fourth valve 43. A third valve 42 is mounted on the second inlet conduit 35. A fourth valve 43 is mounted on the second outlet pipe 36. The third valve 42 is used to open or close the second inlet pipe 35. The fourth valve 43 is used for opening or closing the second outlet pipe 36.

In this manner, the second water inlet pipe 35 may be opened by the third valve 42 to allow water to enter the heating water pipe 31 (as indicated by a dotted arrow of fig. 1), so that the water may flow along the heating water pipe 31 and absorb heat generated from the water in the heating chamber 111. Meanwhile, the second water outlet pipe 36 can be opened through the fourth valve 43 so that the water in the heating water pipe 31 flows out through the second water outlet pipe 36 (as shown by the dotted arrow in fig. 1), thereby realizing the utilization of the water. This allows the water in the heating water pipe 31 to be introduced and removed in a relatively simple manner.

It will be appreciated that in order to avoid excessive water being retained in the second inlet pipe 35 or the second outlet pipe 36 to affect the heating effect, the third valve 42 may be installed at one end of the second inlet pipe 35 adjacent to one end of the heating water pipe 31, and the fourth valve 43 may be installed at one end of the second outlet pipe 36 adjacent to the other end of the heating water pipe 31.

It should be noted that the opening and closing manners of the third valve 42 and the fourth valve 43 can be realized manually or by program control, and can be set according to actual application conditions.

In one example, the plumbing system includes a thermal water jacket (not shown). The heat preservation water jacket is sleeved on the second water outlet pipe 36. Therefore, heat loss of the heated water in the heating water pipe 31 when the water flows through the second water outlet pipe 36 can be effectively prevented.

Referring to fig. 8, in one embodiment, a microwave water heater 100 includes a control device 50. The control device 50 is electrically connected to the third valve 42 and the fourth valve 43. The control device 50 is used to control the open/close states of the third valve 42 and the fourth valve 43.

Specifically, in some embodiments, when the water level in the heating chamber 111 reaches the set water level, the control device 50 controls the third valve 42 to be opened so that water can enter the heating water pipe 31 from the second water inlet pipe 35, and controls the fourth valve 43 to be opened so that water can flow out from the second water outlet pipe 36. The cold water can absorb heat generated from the water in the heating chamber 111 when flowing along the outer wall 112 of the inner container 11 in the heating water pipe 31. Since the water flowing through the heating water pipe 31 is less, the water in the heating chamber 111 can be heated in real time, i.e. the microwave water heater 100 can achieve the heating effect of instant heating and instant heating.

It should be noted that the "set water level" may be set according to specific conditions, for example, in one example, when the heating chamber 111 is filled with water or filled to half capacity, the water level in the heating chamber 111 reaches the set position.

In the present example, the control device 50 is electrically connected to the key 51. The control device 50 is electrically connected to the first valve 40 and the second valve 41. The control device 50 is electrically connected to the third valve 42 and the fourth valve 43. The control device 50 is electrically connected to the water level detecting element 60.

When the microwave water heater 100 is installed, water may be filled in the heating chamber 111. The working principle of the microwave water heater 100 is as follows: after the user activates the button 51, the microwave water heater 100 enters the water-filling state. At this time, the microwave water heater 100 can automatically perform the next operation, that is, the control device 50 controls the first valve 40 to be opened to make the first water inlet pipe 33 communicate with the heating chamber 111, controls the second valve 41 to be closed to make the first water outlet pipe 34 and the heating chamber 111 in a disconnected state, and controls the microwave generator 21 to be in a closed state, that is, the microwave generator 21 cannot emit microwaves to the heating chamber 111. The water can now enter the heating chamber 111 directly from the first inlet pipe 33 and not flow out through the first outlet pipe 34.

When the water level detecting element 60 detects that the water level in the heating chamber 111 reaches the set water level (i.e., the heating chamber 111 is full of water), the control device 50 can control the first valve 40 to close according to the detection result of the detecting element 60 so that the first water inlet pipe 33 is in a disconnected state from the heating chamber 111. At this time, the heating chamber 111 stops water feeding, i.e. the microwave water heater 100 exits the water filling state. At this time, the control device 50 can control the microwave generator 21 to be turned on, i.e., the microwave generator 21 can emit microwaves to the heating chamber 111. Since the water in the heating chamber 111 is small, the water in the heating chamber 111 can be rapidly heated by the microwave emitted from the microwave generator 21.

Meanwhile, when the water level in the heating chamber 111 reaches the set water level, the control device 50 controls the third valve 42 to be opened so that water can enter the heating water pipe 31 through the second water inlet pipe 35, and controls the fourth valve 43 to be opened so that water can flow out through the second water outlet pipe 36. When the water in the heating water pipe 31 flows along the outer wall 112 of the liner 11, the water in the heating water pipe 31 can absorb heat at a relatively high speed, so that the water in the heating water pipe 31 can flow out of the second water outlet pipe 36 at a relatively high temperature in real time, and the microwave water heater 100 can achieve an instant heating effect.

In one embodiment, the microwave water heater 100 includes a display screen 61. The display screen 61 is electrically connected to the control device 50. The display screen 61 is used for displaying the operating state of the microwave water heater 100. In this way, the user can directly read the operating status of the microwave water heater 100 from the display screen 61, thereby facilitating the user operation and improving the intelligence of the microwave water heater 100.

For example, in one example, after the user activates the button 51, the microwave water heater 100 enters the water-filled state, and the display screen 61 displays the microwave water heater 100 in text form to prompt the user that the water-filled state has been entered. In another example, when the water level detecting member 60 detects that the water level in the heating chamber 111 reaches the set water level, the display screen 61 displays the water level in the heating chamber 111 in text to prompt the user.

In one embodiment, an appliance compartment 12 is formed within the body 10. The appliance chamber 12 is located at one side of the inner container 11. The microwave generator 21 is installed in the appliance chamber 12. In this way, the electric chamber 12 has a protective effect on the microwave generator 21, so that substances such as external ash layers or water vapor are not easy to enter the microwave generator 21.

In one embodiment, the inner bladder 11 includes a mounting plate 13. The mounting plate 13 separates the heating chamber 111 and the appliance compartment 12. The microwave generator 21 is mounted on the mounting plate 13.

In this way, the mounting plate 13 is provided to avoid interference between the heating chamber 111 and the appliance chamber 12 and to facilitate mounting of the microwave generator 21.

Specifically, in some embodiments, the mounting plate 13 is a side plate of the inner container 11 and can be detachably mounted on the inner container 11. When the microwave generator 21 needs to be installed, the microwave generator 21 may be installed on the installation plate 13, and then installed together with the other side plates of the inner container 11. Moreover, a sealing element (not shown) such as a silicone ring may be disposed at a connection portion between the mounting plate 13 and the other side plates of the inner container 11, so as to improve the sealing effect of the inner container 11.

In other embodiments, the microwave generator 21 may be directly welded to the inner container 11.

In one embodiment, the mounting plate 13 is a one-piece structure. Therefore, the structure is simple and the manufacture is convenient.

It will be appreciated that the microwave generator 21 may be mounted on the upper, lower, left or right side of the mounting plate 13, as the case may be.

In one embodiment, microwave heating system 30 includes a power supply device 70. The power supply device 70 is installed in the appliance room 12. The power supply device 70 is electrically connected to the microwave generator 21. The power supply device 70 is used to supply power to the microwave generator 21 to excite the microwave generator 21 to emit microwaves into the heating chamber 111.

In this way, the electric appliance chamber 12 has a protective effect on the power supply device 70, so that substances such as dust or moisture from the outside are not easily introduced into the power supply device 70. Meanwhile, because the power supply device 70 and the microwave generator 21 are both arranged in the electric appliance chamber 12, the distance between the power supply device 70 and the microwave generator 21 is short, and the arrangement of electric connection between the power supply device 70 and the microwave generator 21 is convenient.

In one example, the control device 50 is an electronic control board. The control device 50 is electrically connected to the power supply device 70. The control device 50 controls the operating state of the microwave generator 21 by controlling the operating state of the power supply device 70. When the control device 50 controls the power supply device 70 to be in the off state, the power supply device 70 does not operate. At this time, the microwave generator 21 is also in an off state, that is, the microwave generator 21 cannot emit microwaves to the heating chamber 111. When the control device 50 controls the power supply device 70 to be in the on state. At this time, the microwave generator 21 is turned on, i.e., the power supply device 70 supplies power to the microwave generator 21. The microwave generator 21 may emit microwaves to the heating chamber 111 at this time.

In some examples, the frequency of the microwave generated by the microwave generator 21 ranges from 900MHz to 3000MHz. In this way, the water in the heating chamber 111 can be heated rapidly in a short time by the microwave generated by the microwave generator 21.

It should be noted that the power supply device 70 may include a line frequency transformer or an inverter. If the power supply device 70 uses a line frequency transformer, an auxiliary device 71 (shown as a component in a dashed box in fig. 1) for assisting the microwave generator 21 needs to be added, wherein the auxiliary device 71 comprises a high-voltage capacitor or a high-voltage diode. If the power supply device 70 employs an inverter, an auxiliary device for assisting the microwave generator 21 does not need to be added.

In one embodiment, the microwave heating system includes a microwave excitation device 22 and an insulating, wave-transparent device 23 mounted on the liner 11. The microwave excitation device 22 is connected to the microwave generator 21. The microwave generator 21 emits microwaves to the heating chamber 111 through the microwave excitation device 22. The wave-transparent device 23 houses the microwave excitation device 22 and extends into the heating chamber 111. The wave-transparent device 23 separates the microwave generator 21 from the heating chamber 111.

In this way, after the microwave generator 21 emits the microwaves, the microwave excitation device 22 can sufficiently emit the microwaves and can reduce the reflection of the microwaves to the microwave generator 21, thereby preventing the microwaves from damaging the microwave generator 21. Meanwhile, the insulating wave-transmitting device 23 can ensure that the microwave generator 21 is separated from the heating chamber 111, so that water and electricity separation is realized. Meanwhile, the wave-transparent device 23 covers the microwave excitation device 22 and extends into the heating chamber 111, so that the heating efficiency is high and the structure is simple.

In the embodiment shown in fig. 1, the microwave generator 21 is mounted on the mounting plate 13. The wave-transparent device 23 houses the microwave excitation device 22 and is mounted on the mounting plate 13 and within the heating chamber 111. The wave-transparent device 23 separates the microwave excitation device 22 and the microwave generator 21 from the heating chamber 111. The microwave water heater 100 includes a seal (not shown). The sealing member seals the gap between the wave-transparent device 23 and the mounting plate 13. Thus, the sealing effect between the wave-transmitting device 23 and the mounting plate 13 can be ensured, and water in the heating chamber 111 can be prevented from leaking. The seal is made of, for example, a silicone material or a rubber material.

In one embodiment, the thickness of the walls of the wave-transparent device 23 ranges from 1mm to 3mm. Thus, the pressure-bearing capacity of the wave-transmitting device 23 is large.

It should be noted that the thickness of the wall of the wave-transmitting device 23 cannot be too large, and it is necessary to ensure that the microwave generated by the microwave generator 21 can smoothly penetrate through the wave-transmitting device 23.

In some examples, the wall of the wave-transparent device 23 has a thickness of 1mm, 2mm, or 3mm. It should be noted that the thickness of the wall of the wave-transparent device 23 is not limited to the values listed in the above examples.

In some examples, the wave-transparent device 23 is constructed of a non-metallic material, such as glass or ceramic. Preferably, the wave-transparent device 23 is made of a glass material.

In one embodiment, the microwave water heater 100 includes a cooling device 80. The cooling device 80 is installed in the appliance compartment 12. The cooling device 80 is used for forming cold air to cool the components in the electric appliance room 12.

Thus, because cooling device 80 can form cold wind and cool down the components in electrical apparatus room 12 to can guarantee that the temperature of the components in electrical apparatus room 12 can not overtemperature, and then guarantee the safety in utilization of the components in electrical apparatus room 12.

In the embodiment of the present invention, the components in the electric appliance chamber 12 include the microwave generator 21 and the power supply device 70, that is, both the microwave generator 21 and the power supply device 70 are installed in the electric appliance chamber 12. The power supply device 70 is electrically connected to the microwave generator 21. The power supply device 70 is used to supply power to the microwave generator 21 to excite the microwave generator 21 to emit microwaves into the heating chamber 111. Thus, when the microwave water heater 100 is operated, the cooling device 80 can take away heat generated by the microwave generator 21 and the power supply device 70 through cold air, thereby improving the heat dissipation efficiency of the microwave generator 21 and the power supply device 70.

It is understood that, in order to improve the safety of the components and the cooling device 80 in the electric chamber 12, a waterproof layer (not shown) may be coated on the surfaces of the components and the cooling device 80 in the electric chamber 12.

In one embodiment, the body 10 includes a housing 14. The housing 14 is formed with a mounting space 141. The inner container 11 is located in the installation space 141. In this way, the outer shell 14 has a certain protective effect on the inner container 11.

In one embodiment, the microwave water heater 100 includes an insulating element (not shown). The insulating element separates the outer shell 14 from the inner container 11. Thus, the heat insulation element can effectively prevent the heat in the inner container 11 from losing, thereby ensuring the heating effect of the microwave water heater 100.

In one example, the insulating element includes a foaming agent. Thus, the heat insulation element has a better heat insulation effect and a certain sound insulation effect, thereby reducing the noise generated when the electric water heater 100 works.

Referring to fig. 2, in one embodiment, the microwave water heater 100 includes a water jacket structure 81 and a first circulating water pipe 83. The water jacket structure 81 surrounds a heat generation region (not shown) of the microwave generator 21. The first circulation water pipe 83 communicates the water jacket structure 81 and the heating chamber 111.

Therefore, as the first circulating water pipe 83 is communicated with the water jacket structure 81 and the heating chamber 111, water in the heating chamber 111 can enter the water jacket structure 81 through the first circulating water pipe 83 and directly cool the microwave generator 21, which is beneficial to heat dissipation of the microwave generator 21, improves the heat dissipation efficiency of the microwave generator 21 and ensures normal operation of the microwave water heater 100. Further, the water heated by the microwave generator 21 can be returned to the heating chamber 111, so that the temperature of the water in the heating chamber 111 can be increased more quickly.

In the example shown in fig. 2, the first circulation water pipe 83 forms a circulation loop with the heating chamber 111 and the water jacket structure 211, and the first circulation water pipe 83 enables water in the heating chamber 111 to flow into the water jacket structure 211 through one side of the first circulation water pipe 83 and to flow back into the heating chamber 111 through the other side of the first circulation water pipe 83.

In some examples, the first circulating water pipe 83 is formed of one or more of a metal pipe, a temperature-resistant plastic pipe, and a metal-clad plastic pipe.

It will be appreciated that the microwave generator 21 may be grounded in order to improve the safety of use of the microwave generator 21.

It is understood that the following modifications can be made on the basis of fig. 2. Specifically, please refer to fig. 3. The microwave water heater 100 includes a power supply unit 70 and a thermally conductive housing 84. The power supply device 70 is electrically connected to the microwave generator 21. The power supply device 70 is used to supply power to the microwave generator 21 to excite the microwave generator 21 to emit microwaves into the heating chamber 111. The power supply device 70 is thermally connected to the housing 84. The power supply unit 70 is sealed within the housing 84. The power supply device 70 and the housing 84 are both located within the heating chamber 111.

Thus, because the power supply device 70 is located in the heating chamber 111, the water in the heating chamber 111 can directly cool the power supply device 70 through the shell 84, thereby improving the heat dissipation efficiency of the power supply device 70 and ensuring the normal operation of the electric water heater 100.

The thermal connection means that the power supply device 70 and the housing 84 can exchange heat effectively, that is, the power supply device 70 can dissipate heat generated by itself through the housing 84. For example, in some examples, the power supply device 70 and the housing 84 are filled with an insulating heat transfer medium 841 (shown in fig. 3). Wherein, the insulated heat-conducting medium can be heat-conducting silica gel, gum or transformer oil, etc.

It is understood that the following modifications can be made on the basis of fig. 3. Specifically, please refer to fig. 4. The microwave water heater 100 includes a second circulating water pipe 85 communicating with the heating chamber 111 and passing through the interior of the housing 84. Wherein an insulating heat conducting medium 841 is filled between the power supply device 70 and the housing 84. A second circulating water pipe 85 is penetrated through the case 84 and a portion of the second circulating water pipe 85 is located in the case 84. The portion of the second circulation water pipe 85 located within the housing 84 may exchange heat with the heat transfer medium 841. In this way, the circulating water pipe 85 can guide the water in the heating chamber 111 into the housing 84 to take away the heat of the power supply device 70, which improves the heat dissipation efficiency of the power supply device 70. Wherein, the second circulating water pipe 85 has a better temperature-resistant effect.

It is understood that the following modifications can be made on the basis of fig. 4. In the example shown in fig. 4, 4 holes (not shown) need to be formed in the inner container 11. Two holes are respectively formed in two ends of the first circulating water pipe 83 to be communicated with the heating chamber 111, and another two holes are respectively formed in two ends of the second circulating water pipe 85 to be communicated with the heating chamber 111). It is contemplated that too many openings may affect the sealing effect of bladder 11.

Therefore, in the example of fig. 5, 4 holes (not shown) required for opening the inner container 11 in the example of fig. 4 are simplified into 2 holes. One end of the first circulating water pipe 83 is inserted into one of the two holes and is communicated with the heating chamber 111. One end of the second circulating water pipe 85 is perforated through the other of the two holes and communicates with the heating chamber 111. Meanwhile, the other end of the second circulation water pipe 85 communicates with the other end of the first circulation water pipe 83. That is, the water in the heating chamber 111 may first enter the first circulation water pipe 83, then may enter the second circulation water pipe 85 along the first circulation water pipe 83, and finally may flow back into the heating chamber 111 from the second circulation water pipe 85.

The water in the heating chamber 111 cools the microwave generator 21 through the first circulating water pipe 83, and then flows directly into the second circulating water pipe 85 to cool the power supply device 70. Therefore, the electric-heat conversion efficiency of the microwave water heater 100 is improved, the number of holes formed in the inner container 11 is reduced, and the water leakage risk of the inner container 11 is reduced.

It is understood that the following modifications can be made on the basis of fig. 5. To further avoid the formation of holes in the inner container 11, the water pipe can be optimally designed as shown in fig. 6. In fig. 6, one end of the second circulation water pipe 85 is directly set to be in communication with one end of the first circulation water pipe 83, and the other end of the second circulation water pipe 85 is communicated with the second inlet pipe 35 and the other end of the first circulation water pipe 83 is communicated with the second inlet pipe 35.

That is, in the operation of the microwave water heater 100, after the cold water enters the second water inlet pipe 35, the cold water may first enter the first water circulation pipe 83 along one end of the second water inlet pipe 35 and may absorb heat generated by the microwave generator 21, then may enter the second water circulation pipe 85 through the first water circulation pipe 83 and may absorb heat generated by the power supply device 70, then may flow to the other end of the second water inlet pipe 35 through the second water circulation pipe 85, and may finally enter the heating water pipe 31. Therefore, the opening on the inner container 11 is not needed, and the water entering the heating water pipe 31 is equivalently preheated, so that the overall heat conversion efficiency of the microwave water heater 100 is further improved. Wherein the flow path of water is shown by the dotted arrows in fig. 6.

Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.
