[0002] Steam ironing equipment such as steam brush, steam iron, steam garment steamer and other laundry care steam products, usually with water tank and water level sensing device for detecting the liquid level in the water tank. The commonly used water level sensing device is generally a hall switch, a capacitive sensing device or a photoelectric sensing device, such as the water tank water level detection and early warning mechanism of the ironing machine with the application number CN202221732292.4, the water tank and flap type ironing machine with the application number CN201621440079.0, the water level detection assembly of the ironing device and the ironing device with the application number CN202123103700.8 disclose the above water level sensing device.

[0003] But the above-mentioned mechanical water level sensing device also has certain deficiencies, and the water level sensing device added on the water tank increases the cost of ironing products, especially, due to the influence of manufacturing precision, the stability of the mechanical water level sensing device will also have certain problems, so that after being installed on the ironing product, the sensitivity and stability of the water level sensing of the ironing product will also have great uncertainty.

[0004] Therefore, the existing steam ironing equipment needs to be further improved. INVENTION CONTENTS

[0005] The utility model solves the technical problem that the utility model wants to solve is according to the present situation of prior art, provide a kind of steam ironing equipment that can effectively reduce ironing product cost, and can guarantee the sensitivity and stability of water tank water level sensing.

[0006] The technical scheme adopted by the utility model to solve the above technical problem is: a steam ironing equipment, comprising:

[0007] Water tank;

[0008] Vaporization device, including vaporization chamber, the electric heating device for providing heat to gasification chamber and the temperature sensing device for identifying the temperature in the vaporization chamber, the vaporization chamber is communicated with the water tank;

[0009] Water pump, is located in the flow path between the water tank and the vaporization chamber, for transporting the water in the water tank to the vaporization chamber;

[0010] The controller and the timing module are electrically connected with the temperature sensing device and the water pump. The timing module starts timing when the water pump is in working state and the temperature sensing device identifies that the temperature in the vaporization chamber reaches a set temperature. The controller controls the water pump to be turned off and / or controls the alarm device to send a reminder of water shortage in the water tank when the time signal transmitted by the timing module reaches a set value.

[0011] The temperature sensing device of the vaporization device is used to sense the temperature in the vaporization chamber. When the temperature is lower than a set value, the electric heating device is turned on and starts heating to supply heat to the vaporization chamber. When the temperature is higher than the set value, the electric heating device is turned off and stops heating. This can ensure that the vaporization chamber always has enough heat to vaporize the water from the water tank and can also ensure that the temperature in the vaporization chamber and the whole product does not become too high. The "set temperature" in the "when the temperature sensing device identifies that the temperature in the vaporization chamber reaches a set temperature" should be understood as the temperature at which the temperature sensing device controls the electric heating device to stop heating.

[0012] As an improvement, the temperature sensing device is a mechanical temperature controller. The timing module starts timing when the water pump is in working state and the contact of the mechanical temperature controller is disconnected.

[0013] The temperature sensing device is an electronic temperature controller. The timing module starts timing when the water pump is in working state and the electronic temperature controller detects that the temperature in the vaporization chamber reaches a temperature at which the electric heating device stops heating.

[0014] Further improvement, the mechanical temperature controller is a bimetallic strip temperature controller, a liquid expansion temperature controller or a pressure temperature controller.

[0015] As another optional way of the temperature sensing device, the electronic temperature controller includes an NTC temperature sensor for detecting the temperature change in the vaporization chamber.

[0016] In order to reduce the interference of other factors and further improve the accuracy of detecting water shortage in the water tank, the vaporization device further includes a water inlet pipe connected with the vaporization chamber. The mechanical temperature controller is arranged on the vaporization chamber adjacent to the area where the water inlet pipe is located.

[0017] In order to timely and effectively remind the user to pay attention to the water shortage in the water tank, the alarm device is an alarm that can emit sound and / or light. It is conceivable that the alarm device can also remind the user of the water shortage in the water tank by flashing in the form of words or symbols on the display screen or touch screen of the ironing equipment.

[0018] As an improvement, the steam ironing equipment is one of an iron, a steamer and a steam ironing brush.

[0019] Compared with the prior art, the utility model has the advantages that: directly using the temperature sensing device of the steam vaporizing device of the steam ironing product (a set of temperature sensing device required by basically all steam products) to sense the temperature change of the vaporizing chamber, when the temperature sensing device is in the off state and accumulates to a certain time t (the specific time will be different due to the product, and the time can be understood as that after enough time, the temperature control program of the product judges that the temperature of the vaporizing chamber does not obviously drop, and the heating condition is not reached), it is judged that the water pump does not pump enough water from the water tank into the vaporizing chamber when the water pump works, that is, the water pump is in the empty pumping state, and the water pump cannot pump water from the water tank, so that it is judged that the water tank is in the waterless state. At this time, the product starts the waterless protection program (such as automatically turning off the water pump, water tank waterless prompt and the like) to remind the consumer, so that the purpose of protecting the product is achieved. Since the temperature sensing device of the steam ironing product is directly used, a separate temperature sensing system is not needed to sense the temperature change in the vaporizing chamber, so that other costs are not needed, and the cost advantage of the product is greatly improved. Compared with the water level sensing device arranged on the water tank in the prior art, the water tank water level detection mode is not affected by the manufacturing precision, is less affected by external factors, and can guarantee the sensitivity and stability of the water tank water level sensing.

[0021] Fig. 2 It is a sectional view of the vaporizing device of the steam ironing equipment of the utility model embodiment. DETAILED DESCRIPTION

[0022] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0023] In the description and claims of the utility model, directional terms such as "front", "back", "up", "down", "left", "right", "side", "top", "bottom" and the like are used to describe various example structural parts and elements of the utility model, but these terms are used only for the convenience of description purposes, and are determined based on the example orientation shown in the drawings. Since the disclosed embodiments of the utility model can be arranged in different directions, these directional terms are only used for description and should not be regarded as limitation, for example, "up" and "down" are not necessarily limited to the direction opposite or consistent with the direction of gravity.

[0024] Figs. 1-2A preferred embodiment of the steam ironing apparatus is shown. The steam ironing apparatus can be one of an iron, a garment steamer, a steam ironing brush and the like steam products for garment care, which generally comprises a water tank 10, a vaporizing device 2 and a water pump 12.

[0025] The water tank 10 is used for storing water for the vaporizing device 2 to form steam, and the water tank 10 can be fixed or detachable. The water tank 10 is connected to the vaporizing chamber 20 of the vaporizing device 2 through a water supply pipe 11. The water pump 12 is arranged in the flow path between the water tank 10 and the vaporizing chamber 20 on the water supply pipe 11, and when the water pump 12 is started, the water in the water tank 10 can be delivered to the vaporizing chamber 20.

[0026] The vaporizing device 2 comprises a vaporizing chamber 20, an electric heating device 22 for providing heat to the vaporizing chamber and a temperature sensing device 23 for sensing the temperature in the vaporizing chamber 20. The electric heating device 22 can be a conventional electric heating pipe arranged on the bottom wall of the vaporizing chamber 20. The temperature sensing device 23 provided with the vaporizing device 2 is used to sense the temperature of the vaporizing chamber 20, when the temperature is lower than the set value, the electric heating device 22 is connected to start heating to supplement heat to the vaporizing chamber 20, when the temperature is higher than the set value, the electric heating device 22 is disconnected, and the electric heating device 22 stops heating, which can ensure that the vaporizing chamber 20 always has enough heat to vaporize the water from the water tank 10, and can also ensure that the temperature of the vaporizing chamber 20 and the whole product will not be too high. The steam formed by the vaporization of the water in the vaporizing chamber 20 can be discharged from the steam outlet 200.

[0027] The temperature sensing device 23 of the present embodiment can be a mechanical temperature controller or an electronic temperature controller, wherein the mechanical temperature controller can be a bimetallic strip temperature controller, a liquid expansion temperature controller or a pressure temperature controller. The electronic temperature controller comprises an NTC temperature sensor (i.e. a thermistor temperature sensor) for detecting the temperature change in the vaporizing chamber 20.

[0028] The controller 3 of the steam ironing device of the present embodiment is electrically connected with the temperature sensing device 23, the water pump 12 and the electric heating device 22 as described above. The controller 3 is provided with a timing module (not shown) configured to start timing when the water pump 12 is in the working state and the temperature sensing device 23 identifies that the temperature in the vaporization chamber 20 reaches the set temperature. When the time signal transmitted by the timing module reaches the set value (this specific time may vary for different products, and this time set value can be understood as that after enough time, the temperature control program of the product judges that the temperature in the vaporization chamber 20 does not decrease significantly and does not meet the heating condition), the controller 3 controls the water pump 12 to be turned off and / or controls the alarm device to issue a reminder that the water tank 10 is out of water. It can be understood that the "set temperature" in the "temperature sensing device 23 identifies that the temperature in the vaporization chamber 20 reaches the set temperature" should be understood as the temperature at which the temperature sensing device 23 sets to control the electric heating device 22 to stop heating.

[0029] When the temperature sensing device 23 adopts a mechanical temperature controller, the timing module is configured to start timing when the water pump 12 is in the working state and the contact of the mechanical temperature controller is disconnected. When the temperature sensing device 23 is in the disconnected state and accumulates a certain time t, it is determined that the water pump 12 does not pump enough water from the water tank 10 into the vaporization chamber 20 when it is working, i.e. the water pump 12 is in the empty pumping state, and the water pump 12 cannot pump water from the water tank 10, thereby determining that the water tank 10 is in the waterless state. At this time, the product will start the waterless protection program (such as automatically turning off the water pump 12, water tank 10 waterless prompt, etc.) to remind the consumer, thereby achieving the purpose of protecting the product. Since the temperature sensing device 23 of the vaporization device 2 of the steam ironing product is directly used in the present embodiment, there is no need to separately set a set of temperature sensing system to sense the temperature change in the vaporization chamber 20, thereby not needing to increase other costs and greatly improving the cost advantage of the product. Compared with the water level sensing device provided on the water tank 10 in the prior art, this water level detection method of the water tank 10 is not affected by the manufacturing precision and is less affected by external factors, and can ensure the sensitivity and stability of the water level sensing of the water tank 10.

[0030] Referring to Fig. 2 The top of the vaporization device 2 includes a water inlet pipe 21 connected with the vaporization chamber 20, which is used to connect with the water supply pipe 11 as described above. The mechanical temperature controller is arranged at the bottom of the vaporization chamber 20 and adjacent to the area where the water inlet pipe 21 is located. Since the temperature controller is arranged adjacent to the water inlet end of the vaporization chamber 20, it directly detects the temperature of the water inlet end area of the vaporization chamber 20, so as to reduce the interference of other factors as much as possible and further improve the accuracy of detecting the water shortage of the water tank 10.

[0031] It is conceivable that the temperature sensing device 23 can also adopt an electronic temperature controller. When the electronic temperature controller is adopted, the timing module is configured to start timing when the water pump 12 is in operation and the electronic temperature controller detects that the temperature in the vaporization chamber 20 reaches the temperature at which the electric heating device 22 stops heating (i.e. the temperature control relay of the NTC is opened). When the relay of the electronic temperature controller is in the open state for a certain time t, it is determined that the water pump 12 does not pump enough water from the water tank 10 into the vaporization chamber 20 when it is in operation, i.e. the water pump 12 is in the empty pumping state.

[0032] In order to effectively remind the user to pay attention to the water shortage of the water tank 10 in time, the ironing device can be provided with an alarm device. The alarm device can adopt an alarm that can emit sound and / or light, such as a horn that emits a buzzing sound or an indicator light that can flash. Of course, for the steam ironing device with a display screen or a touch screen, the alarm device can also be to remind the user that the water tank 10 is short of water by "flashing in words or symbols on the display screen or touch screen of the ironing device".

[0033] Since the steam ironing device of the present embodiment directly uses the temperature sensing device 23 of the vaporization device 2 of the steam ironing product itself to obtain the temperature signal, it is not necessary to separately set a set of temperature sensing system to sense the temperature change in the vaporization chamber 20, thus no additional cost is needed, and the cost advantage of the product is greatly improved. Compared with the water level sensing device provided on the water tank 10 in the prior art, this water level detection method is not affected by the manufacturing precision and is less affected by external factors, and can ensure the sensitivity and stability of the water level sensing of the water tank 10.
