Description

Technical Field

[0001] This invention belongs to the field of thermostat technology, specifically relating to a hotel bathroom thermostat. Background Technology

[0002] A thermostat is an automatic control element that, based on changes in the ambient temperature, undergoes internal physical deformation to produce specific effects, resulting in either switching on or off. It is also called a temperature switch, temperature protector, or temperature controller, and is often simply called a thermostat. Alternatively, the temperature protector transmits the temperature data to the temperature controller, which then issues a switching command to control the equipment's operation to achieve the desired temperature and energy-saving effect.

[0003] Thermostats are widely used in smart homes, hotels, and other similar locations. In the current technology, thermostats used in hotel bathrooms typically employ a simple display screen and control buttons to set the temperature threshold.

[0004] Chinese patent CN111966146B discloses a smart home bathroom thermostat, including a mounting plate and a thermostat body. The thermostat body is mounted on the surface of the mounting plate, and a protruding plate is integrally formed on the surface of the mounting plate. The surface of the protruding plate has an installation groove, in which the thermostat body is installed. A fixing shell is provided outside the protruding plate and is slidably connected to the outside of the protruding plate. A connecting groove is formed on the surface of the fixing shell and is connected to the inside of the installation groove. The length and width of the connecting groove are smaller than the length and width of the thermostat body. This smart home bathroom thermostat has a simple overall structure and ingenious design. When installing the thermostat body, there is no need to add or remove corresponding parts to the body, thus preserving its original form. Only one person is needed to install the thermostat body conveniently and quickly, saving labor and improving installation efficiency. The disassembly of the thermostat body is also very convenient and quick, greatly facilitating the maintenance of the thermostat body by repair technicians.

[0005] While this structure facilitates maintenance, it does not improve ease of use. In cold weather, the shower temperature in the bathroom needs to rise before the air temperature, and the display screen on the thermostat cannot heat up quickly enough, causing condensation on the control interface. Because the display screen cannot heat up quickly, even if the condensation is wiped away, it will fog up again quickly, affecting its usability. Summary of the Invention

[0006] The purpose of this invention is to provide a hotel bathroom thermostat to solve the problem in the above-mentioned background technology where water vapor continuously adheres to the surface of the display screen, affecting the ease of use of the thermostat's control interface.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A hotel bathroom thermostat includes a base, a control panel on one side of the base, a magnetic temperature probe on one side of the control panel, a self-winding mechanism for the magnetic temperature probe inside the control panel, a ventilation structure on one side of the control panel, a circuit board and a ventilation drive inside the base, and a heating and demisting component inside the control panel.

[0009] Preferably, the heating and demisting assembly includes heating elements, and two heating elements are provided. The two heating elements are respectively fixed to the inner walls on both sides of the control panel by screws. The heating elements are electrically connected to the circuit board. An insulation board is fixed inside the control panel by screws.

[0010] Preferably, the control panel includes a housing, a display screen, and control buttons. The display screen is fixed inside the housing with screws. The insulation board is U-shaped. The display screen is located between the insulation board and the housing. A heating cavity is formed between the display screen and the insulation board. A circuit protection structure is provided on the side of the insulation board away from the display screen.

[0011] Preferably, the ventilation structure includes an air inlet, an air outlet, and a guide vane, the guide vane being located between the air inlet and the air outlet, and both the air inlet and the air outlet being connected to the heating chamber.

[0012] Preferably, the ventilation drive includes a micro air pump, one end of which is connected to an air outlet.

[0013] Preferably, the line protection structure includes a protective sleeve, one end of which is bonded to the insulation board, and the other end of which is provided with a protruding ring. The outer walls on both sides of the protruding ring are provided with integrally formed limiting protrusions, and the protective sleeve is filled with absorbent cotton.

[0014] Preferably, the circuit protection structure further includes a boss, which is glued to one side of the circuit board. A circular groove is formed in the boss, and a limiting groove is formed in the groove. The protruding ring is inserted into the groove, and the limiting protrusion is inserted into the limiting groove.

[0015] Preferably, a humidity sensor is soldered to one side of the circuit board, the humidity sensor is electrically connected to the circuit board, and mounting holes are provided at both ends of the circuit board.

[0018] The hotel bathroom thermostat proposed in this invention has the following advantages compared with the prior art:

[0019] 1. This invention, by setting up a heating and defogging component and a ventilation structure, and by installing a heat preservation plate in the control panel, allows the heating and defogging component inside the thermostat to work first before the hot water in the bathroom is used. The heating chamber can be heated in advance to preheat the display screen, avoiding excessive condensation and water mist on the display screen surface when hot water is used. This heating structure can improve the ease of use of the display screen, eliminating the need to frequently wipe the display screen surface with water when adjusting the threshold.

[0020] 2. By setting up a ventilation structure, the present invention enables the thermostat to exchange air with the outside air of the bathroom, preventing water mist from entering the thermostat and not being quickly removed, which could cause water stains to corrode the wiring points on the circuit board. This structure can improve the service life of the thermostat. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figure 1-9 The hotel bathroom thermostat shown includes a base 1, a control panel 2 on one side of the base 1, a magnetic temperature probe 3 on one side of the control panel 2, a self-winding mechanism 4 for the magnetic temperature probe 3 inside the control panel 2, a ventilation structure 5 on one side of the control panel 2, a circuit board 6 and a ventilation drive inside the base 1, and a heating and demisting component inside the control panel 2.

[0033] In use, an installation opening is provided in the bathroom wall. The base 1 is fixed in the installation opening with screws, and the wiring in the bathroom is connected to the circuit board 6 through the wiring port. Then, the ventilation drive connection pipe is connected to the outside of the bathroom. The circuit board 6 and the display screen 1001 are connected by wires. The magnetic temperature probe 3 is manually pulled out when it is necessary to measure the temperature at a fixed point in the bathroom, and it is attached to the wall with a magnetic sheet. When it is not necessary to measure the temperature at a fixed point, it is kept on one side of the control panel 2. Figure 1 As shown, it can directly measure the temperature inside the bathroom;

[0034] The heating and demisting assembly includes a heating element 701. Two heating elements 701 are provided. The two heating elements 701 are fixed to the inner walls on both sides of the control panel 2 by screws. The heating elements 701 are electrically connected to the circuit board 6. An insulation plate 702 is fixed inside the control panel 2 by screws.

[0035] By setting up a heating element 701, the heating element 701 generates heat when powered on, which raises the temperature inside the heating chamber 1003, thereby gradually heating up the display screen 1001 and preventing the surface temperature of the display screen 1001 from being too low. When the water temperature in the bathroom is high, water vapor will condense on the surface of the thermostat due to pre-cooling. The insulation board 702 is made of non-combustible rubber insulation material, which reduces heat loss when the heating element 701 heats up.

[0036] The control panel 2 includes a housing 10, a display screen 1001, and control buttons 1002. The display screen 1001 is fixed inside the housing 10 with screws. The insulation plate 702 is arranged in a U-shape. The display screen 1001 is located between the insulation plate 702 and the housing 10. A heating cavity 1003 is formed between the display screen 1001 and the insulation plate 702. A circuit protection structure 8 is provided on the side of the insulation plate 702 away from the display screen 1001.

[0037] The control panel 2 is located outside the wall after the thermostat is installed. Threshold adjustment is performed via control button 1002, and the thermostat's operating status is displayed on screen 1001. The circuit protection structure 8 increases the distance between the display screen 1001 and the circuit board 6, and protects the wires within that distance.

[0038] The ventilation structure 5 includes an air inlet 501, an air outlet 502, and a guide plate 503. The guide plate 503 is located between the air inlet 501 and the air outlet 502. Both the air inlet 501 and the air outlet 502 are connected to the heating chamber 1003. The thermostat is set to timed internal ventilation. After a period of use, the micro air pump 504 automatically starts. The air inlet 501 is connected to an air pipe leading out of the bathroom, and the air outlet is connected to the micro air pump 504. The other end of the micro air pump 504 is also connected to the outside of the bathroom through an air pipe. By drawing air from outside the bathroom into the heating chamber 1003 and drawing air from inside the heating chamber 1003 out of the thermostat through the micro air pump 504, the air inside the thermostat is exchanged with the outside air, increasing the air flow speed inside the thermostat and preventing humid air from remaining inside the thermostat for a long time, which could cause the thermostat to become damp and damaged.

[0039] The ventilation drive includes a miniature air pump 504, one end of which is connected to an air outlet 502.

[0040] The line protection structure 8 includes a protective sleeve 801. One end of the protective sleeve 801 is bonded to the insulation board 702. The other end of the protective sleeve 801 is provided with a protruding ring 802. The outer walls on both sides of the protruding ring 802 are provided with integrally formed limiting protrusions 803. The protective sleeve 801 is filled with absorbent cotton 804.

[0041] By setting up a protective sleeve 801, when connecting the display screen 1001 and the circuit board 6, the wires on the circuit board 6 are passed through the protective sleeve 801, and water-absorbing cotton 804 is filled inside the protective sleeve 801 to reduce the water mist in the heating chamber 1003 from contacting the circuit board 6 through the protective sleeve 801.

[0042] The circuit protection structure 8 also includes a boss 805, which is glued to one side of the circuit board 6. A circular groove 806 is formed in the boss 805, and a limiting groove 807 is formed in the groove 806. A protruding ring 802 is inserted into the groove 806, and a limiting protrusion 803 is inserted into the limiting groove 807. By setting the boss 805 structure, it is easy to align the housing 10 with the base 1 when they are connected.

[0043] A humidity sensor 808 is soldered to one side of the circuit board 6 and is electrically connected to the circuit board 6. Mounting holes 601 are provided at both ends of the circuit board 6. By setting the humidity sensor 808, when the humidity in the space where the circuit board 6 is located reaches the set value, the circuit board 6 automatically displays the data on the display screen 1001 and notifies the maintenance personnel to disassemble and maintain it.

[0044] One side of the base 1 is provided with an integrally formed rim 101. One side of the rim 101 is provided with a screw hole 102 for fixing to the housing 10. An integrally formed pad 103 is provided on the inner wall of the rim 101. The circuit board 6 and the pad 103 are fixedly connected by screws. The screw hole 102 facilitates the connection between the rim 101 and the housing 10.

[0045] The self-winding mechanism 4 includes a housing 401, with a wire inlet groove 402 at one end. A helical torsion spring 403 is fixed inside the housing 401, and a wire 404 is wound around the outside of the torsion spring 403. One end of the wire 404 is fixed to the housing 401, and the other end of the wire 404 passes through the housing 401 and is fixedly connected to the magnetic temperature probe 3. This structure is an automatic winding structure, which is the same as the internal structure of a measuring tape in the prior art. The internal helical torsion spring 403 enables the wire 404 to be automatically wound up. When the magnetic temperature probe 3 needs to be pulled out for use, its magnetic head can be fixed to the wall with a magnetic block, thus realizing fixed-point temperature measurement.

[0046] In use: Within 5 minutes of using the bathroom, prioritize turning on the heating element 701 via the control button to allow it to heat up automatically, heating the air in the heating chamber 1003 and thus the display screen 1001. When using hot water in the bathroom, since the display screen 1001 has already reached the bathroom's indoor temperature, water vapor will not quickly condense on it, affecting its use. When the magnetic temperature probe 3 needs to measure temperature at a fixed point, its magnetic head can be directly pulled out and attached to the wall, improving the accuracy of temperature measurement at that point. The thermostat is set to timed internal ventilation. After a period of use, the micro air pump 504 automatically starts, drawing air from outside the bathroom into the heating chamber 1003 and then drawing air from the heating chamber 1003 out of the thermostat, thus exchanging air inside the thermostat with outside air. This increases the internal airflow speed and prevents humid air from remaining inside the thermostat for extended periods, which could cause moisture damage. This design improves the lifespan of this type of thermostat.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
